A process for the continuous production of alkaline earth metal hydroxide by continuously providing an aqueous alkaline earth metal halide solution to the anode compartment and an aqueous alkaline earth metal hydroxide solution or water to the cathode compartment of an electrolytic cell in which an anode and a cathode are maintained in separate anode and cathode compartments, respectively, by a stable, hydrated, cation selective, hydraulically impermeable, electrically conductive membrane interposed between said anode and said cathode; electrolyzing the alkaline earth metal halide solution; and continuously removing alkaline earth metal hydroxide solution and hydrogen from the cathode compartment and halogen from the anode compartment. The membrane is a film of a fluorinated polymer with pendant side chains containing sulfonyl groups present as ion exchange sites and attached to carbon atoms which have at least one fluorine atom attached thereto. In another embodiment the membrane is a laminate of two such polymers differing in equivalent weight.

An arrow rest for use with archery bows includes an arrow supporting launcher that provides vertical movement to dampen any up and down movement of the arrow shaft when it is shot from the bow, such as up and down vibrational movement which occurs as a result of using a mechanical arrow release aid. The launcher includes a V-groove to support and guide the arrow. The rest also includes a pair of flippers which extend generally upwardly and in the direction of arrow travel along opposite sides of the arrow shaft supported on the launcher to lessen the chance that the arrow shaft will slide off the launcher. Either feature of the rest can be used alone without the other.

A method for forming a silica coating on at least a portion of the surface of alkaline earth metal carbonate particulates in aqueous suspension and the silica-coated alkaline earth metal carbonate so produced are claimed. The claimed method consists of allowing soluble silicate ions in the aqueous phase to slowly react with the alkaline earth metal carbonate surface to form silica micro-particulates on the surface. This silica coating confers upon the composition unique properties among which are pronounced thixotropic behavior when incorporated into an aqueous suspension and increased oil absorption when dry. The pigment produced by this method is especially suited for use as a filler in paper.

An archery bow stabilizer is made up of a plurality of blocks of a solid resilient material such as a rubber material joined together in end-to-end relationship. Threaded sleeves in each end of each block allow the blocks to be joined together and the joined together blocks to be secured to the handle riser of a bow in normal manner using threaded studs. Usually three to four joined blocks will provide satisfactory stabilization for most bows but more or less blocks may be used when desired. The invention also contemplates stabilizers with rubber or similar resilient material exterior surfaces to eliminate most noise created by the stabilizer during knock-around in the field.

An archery broadhead has twelve broadhead blade receiving slots to receive a plurality of broadhead blades in selected slots. A variety of different orientations of two blades, three blades, four blades, or more can be used to assemble a desired broadhead. By providing blades of different weights and a selection of different weight points and collars, the archer is given the opportunity to create a broadhead of blade configuration and weight as desired. A spearhead point with only two cutting blades and convex faces between the blades provides improved cutting and penetration of a target.

Archery broadhead

A special tuning point for archery arrows for use in tuning a bow, target shooting, and non-big game hunting has a weight approximately equal to a broadhead selected for use by an archer using and tuning the bow and has a balance point position ahead of the arrow shaft to which the point is secured approximately equal to that of the selected broadhead. The tuning point is secured to the forward end of an arrow shaft substantially identical to that used with the selected broadhead to form a tuning arrow. The tuning arrow is used in tuning the bow. In this manner, the bow is properly tuned for not only the tuning arrow, but also for the arrows with the selected broadhead.

Archery arrow tuning, practice, and field point

An archery bow is tuned by making a tuning arrow that either has a tuning point rather than a broadhead, wherein the tuning point compensates for the weight and balance of the broadhead, weight at the rearward portion of the arrow instead of fletching and which compensates for the weight and balance of the fletching, or both. This produces a tuning arrow having substantially the same weight and balance point as the arrows to be shot from the bow during normal shooting. The tuning arrow is used to tune the bow and because the weight and balance point are substantially equal to the weight and balance point of the arrows normally shot from the bow, the tune obtained using the tuning arrow is the correct tune for the normal arrows also.

A granular product for use as a raw material for glass manufacture is composed of at least one alkaline earth metal silicate intimately admixed with at least one alkali metal carbonate or hydroxide. Glass containing fewer gas bubble inclusions and undissolved-particle defects can be produced more readily.

Alkaline earth metal silicate compositions for use in glass manufacture

A novel alkaline earth metal carbonate product for use as a raw material in the glass manufacturing process is disclosed. The alkaline earth metal carbonate becomes a part of the liquid phase in the glass furnace more readily and at a lower temperature; it decomposes to release carbon dioxide gas more rapidly so that all of the gas can escape from the molten glass more easily. Using these alkaline earth metal carbonate compositions, the production capacity of a glass furnace is increased.

Dense, granular alkaline earth metal carbonate and alkali metal salt

A process is provided to react anhydrous carbonate with a particle size between 300 and 74 micrometers and hydrogen peroxide containing a hydroxyalkylidene diphosphonic acid to produce sodium carbonate perhydrate containing 13% to 141/2% active oxygen. The process differs from the prior art in that reaction mixture is substantially dry at all times. The product is stable even without added stabilizers.

Sodium carbonate perhydrate process

A glass manufacturing process using a granular, free-flowing form of alkaline earth metal carbonate, e.g., barium or strontium carbonate, is disclosed. The alkaline earth metal carbonate has a relatively high bulk density and is made without sintering, grinding, or briquetting. The carbonate is prepared from a fine particle size material by the following steps:

Glass manufacture using dense, unsintered, granular alkaline earth metal

A method of converting fine particle size alkaline earth metal carbonate, e.g., barium or strontium carbonate, into a free-flowing granular form with relatively high bulk density, without sintering, grinding, or briquetting, is disclosed. It involves the following steps:

Method of forming dense, unsintered, granular alkaline earth metal

A strontium or barium carbonate product that is better suited for use as a glass ingredient is obtained by sintering the powdered carbonate in a kiln lined with fused amorphous silica. The carbonate picks up fewer harmful contaminants from the amorphous silica lining than it does from, say, a refractory silica-alumina brick lining or a kiln having a metallic inner surface.
