A low temperature method of forming a circuit pattern on a plastic substrate which comprises applying a slurry of a vaporizable solvent, metal particles and a small quantity of binder in the shape of the circuit pattern desired to a removable layer, vaporizing the solvent, covering the powdered metal and binder with an adhesive to hold the powdered metal and carrier in place on the removable layer, laminating the hydrocarbon containing substrate with pressure and heat to cause compacting of said powder and bonding of said compacted powder to said substrate by adhesive layer, said heat being insufficient to destroy said adhesive, substrate and removable layer, and separation of the removable layer. A circuit pattern held on a removable layer by an adhesive overlying same is also disclosed.

Method of making high metal content circuit patterns on plastic boards

This invention describes a platable plastic material that uses a phosphide compound as a filler at levels of 5 to 40 weight percent. The phosphide filler used in this way has good dielectric properties and is non-conductive, but the phosphide provides coupling sites for a conductive plating to initiate and to bond to the filler and thus to the plastic. Surface treatment of the plastic may be needed to expose the particles but this invention removes requirements for catalytic treatment with noble metal chlorides and relies on bonding mechanisms other than the mechanical grip on a rough surface.

Article formed by electroless plating

An electrically powered log splitter has a frame carrying a pair of mutually spaced fixed splitting components with a carriage mounted movable splitting component movable in opposite directions therebetween. A reversible electric drive motor is mechanically connected to the carriage to propel the carriage in opposite directions. A control switch is electrically connected between a power source and the drive motor. The switch has a first closed setting at which the drive motor is energized to move the carriage and its movable splitting component in one direction toward one of the fixed splitting components, a second closed setting at which the drive motor is energized to move the carriage and its movable splitting component in the opposite direction towards the other of the fixed splitting components, and a third normally open setting at which the drive motor is deenergized to halt movement of the carriage. An operating handle is provided to manually adjust the switch from its normally open third setting to either of its first or second closed settings. A shuttle rod is formed integrally with the operating handle and is engageable by the carriage to adjust the switch from either of its first or second closed settings to its normally open third setting in order to limit carriage movement in either direction. With minor modifications, essentially the same arrangement can be employed to operate a single-acting log splitter wherein the carriage mounted movable splitting component coacts with a single fixed splitting component.

Electrically powered log splitter

A double acting log splitter has a longitudinally extending frame with a pair of mutually spaced fixed splitting components located along the length thereof. A movable splitting component is mounted on a carriage which is movable in opposite directions along the length of the frame between the fixed splitting components. The movable splitting component is arranged to coact with either of the stationary splitting components to split a log placed longitudinally therebetween. The carriage is driven in opposite directions by an operating mechanism which includes a nut carried by the carriage for movement therewith and a screw having one end fixed axially by and rotatably supported in bearings located at one end of the frame. The screw extends through the nut in threaded engagement therewith, with the opposite end of the screw preferably extending in an unsupported cantilever fashion beyond the nut and carriage. A reversible drive motor is connected to the supported end of the screw for rotatably driving the screw in one direction to move the carriage towards one of the fixed splitting components, and in the opposite direction to move the carriage towards the other of the fixed splitting components.
