A foam glass aggregate slicing and reduction machine and system which rapidly, effectively, and economically reduces large pieces of aggregate to required sizes with minimal powdery waste. The machine comprises a foam glass aggregate collection chute having a bottom outlet section for discharging foam glass aggregate onto a holdbar located adjacent to the outlet section. A rotating roller supports a plurality of rotating roller knives which slices large pieces of foam glass aggregate to reduce the aggregate to fragments, with minimal powdery waste. A foam glass aggregate guide member directs foam glass aggregate towards the rotating roller. A foam glass aggregate filtering bar having rows of intervening spaces is located below the guide member and adjacent to the rotating roller.

A ladder mounting and retaining system for use on building parapets utilizes a parapet support member secured to the parapet of a building, a ladder support member for retaining the sides of the lengths of a ladder, and a connecting member in the form of a threaded rod, interconnecting the parapet support member and the ladder support member for maintaining these members at a given distance from each other. The parapet support member is secured in position by locking nuts threaded around the connecting member and the ladder support member is secured over the outboard edge of the parapet by retention members. Ladder supports are adjustable on the ladder support member to accommodate ladders of different widths.

A pick-up truck bed toolbox system utilizes a tool storage box which, in its stored, stationary position, rests on the floor of the bed of a pick-up truck such that it is parallel to the side wall of the truck. Electric motors, which can be remotely operated, are utilized to rotate dual, upstanding screw shafts which are connected via laterally extending cantilever arm members to the front and rear ends of the toolbox. The screw shafts raise the toolbox from its resting position on the floor of the bed of the pick-up truck, to an elevated position over the floor, and the shafts then operate to move the arm members laterally to extend the tool box to a position passed the side wall. The screw shafts can then be activated to lower the tool box to a lowered position outside the truck, adjacent to and alongside the sidewall, thus providing easy and ready access to the toolbox. The same system is utilized to return the toolbox from this lowered position outside the truck, to the floor of the truck bed.

Planning organizer

An intrauterine device providing a membrane to cover substantially the entire surface of the uterine cavity, said device having a Y- and or V-shaped resilient member with two diverging arms, a membrane covering the entire area between the diverging arms and, in addition, extending above an imaginary line passing through the terminal ends of the arms, and a flexible tail or string connected to the intersection of the arms for aiding in the removal of the device from the uterus when desired. Optionally, the arms may having a plurality of flexible spurs extending therefrom for maintaining the intrauterine device in position within the uterus.

A chemically reactive electro-fluidized bed gas purification arrangement and method for cleaning a dirty gas stream including chemically reactive materials and entrained particulate materials wherein means are provided to impose a selected electrical charge upon the entrained particulate materials, and wherein the dirty gas stream is contacted with at least one fluidized bed of particulate purification material including reagent material of selected chemical composition receptive to combination with the chemically reactive materials of the dirty gas stream where the reactive bed can be electro-fluidized and the dirty gas stream is passed through at least one electro-fluidized bed where the electrical charged particulate matter entrained in the dirty gas stream adhers to particles of the electro-fluidized bed which act as electro-static collection sites for the particulate material.

An intrauterine device providing a membrane to cover substantially the entire surface of the uterine cavity, said device having a Y- or V-shaped resilient member with two diverging arms, a membrane covering the entire area between the diverging arms and, in addition, extending above an imaginary line passing through the terminal ends of the arms, and a flexible tail or string connected to the intersection of the arms for aiding in the removal of the device from the uterus when desired. The ends of the diverging arms have enlarged end portions and the arms are of unequal length so that the arms may be resiliently collapsed and placed in a tubular inserter with the enlarged end portions longitudinally spaced in the inserter.

A continuous moving bed filter arrangement including a generally vertical vessel defining a gas cleaning chamber therein, having granular filter media inlet opening means located in the upper portion thereof, granular filter media outlet opening means located in the lower portion thereof, at least one first gas conduit means communicating with the upper end thereof, at least one plenum means surrounding a portion of the circumference of a segment of the vessel adjacent the lower portion of the vessel; at least one second gas flow conduit means to conduct gas between the plenum means and the gas cleaning chamber defined by the vessel; at least one third gas conduit means communicating with the plenum means; filter media inlet tube means extending downwardly from the media inlet opening a selected distance into the gas cleaning chamber defined by the vessel for selective admission of granular filter media to the chamber defined within the vessel whereby media flows downwardly through the vessel from the filter media inlet opening to the media outlet opening while gas flows between the first gas conduit means and the second gas conduit means through the bed of media flowing downwardly within the vessel.

The dust collecting efficiency of a gravel bed filter system in which a plurality of filter modules receive dirty gas from and dischage backflush gas and collected dust into a plenum chamber is enhanced by continuously drawing gas from a downstream end of the plenum chamber, passing the withdrawn gas through a cyclone separator, and returning the gas to the upstream end of the plenum chamber.
