Abstract: This invention comprises a driven conveyor for transporting work pieces into one or more flood plating cells for electroplating a metal onto the planar surfaces and surfaces of the through holes of the work piece. An electrolyte solution is pumped by one or more recirculating pumps into the flood cell at such a rate as to maintain the liquid at a desired level covering the anodes and work pieces while work pieces are moved through the cells. One or more power sources provide direct current to the anodes and to the electrified contactors to transmit electrical current to the work pieces. The electrified contactors are positioned across the path of the work piece and spaced outside of the flood cell such that the electrolyte solution does not contact the contactors. Plating will occur so long as the work piece is in contact with one or more of the electrified contactors and the electrolyte.

Abstract: A method to make volumetric additions of dilute aqueous acid solutions to a colloidal catalyst bath that will retard the salt crystallization. The process includes the steps of measuring the volumetric loss of water by physical measurements and adding dilute aqueous acid solution to the bath in the amount of the loss or by measuring the density or specific gravity of the solution and adding dilute aqueous acid solutions to maintain the specific gravity in the desired range.

Abstract: This invention is a process to rejuvenate the depleted metal salt oxidizing agents used in microetch cleaning compositions and to maintain the desired etch rate. This process comprises the steps of: (1) measuring the reduced metal salt oxidizing agent in the microetch cleaning composition, (2) adding a rejuvenating agent in a stoichiometric or sub-stoichiometric quantity, and (3) mixing and allowing the rejuvenating agent to react with the reduced metal salt oxidizing agent to restore the concentration of the metal salt oxidizing agent to its approximate concentration in the original microetch cleaning composition.
Abstract: This invention is a device to specifically develop certain muscle groups and techniques for golfers by utilizing a variable resistance means which may be attached to an object such as a door and utilizes a simulated golf club, D-handle or waist belt to permit free rotational movement of the users limb or torso through a series of exercises. The D-shaped handle having a stirrup and a roller located between the stirrup to allow axial movement of the roller and the stirrup relative to the variable resistance means. The waist belt having teeth on the rubber liner to prevent slipping of the belt upon the user turning their body. The variable resistance means being lengths of rubber tubing which vary the resistance as the user pulls against it.
Abstract: This invention relates to a weight lifting belt which includes grips for a trainer to assist in training a lifter the proper techniques for lifting.
Abstract: A safety device for firearms having trigger interrupting means operably connected to the trigger mechanism of the firearm. The code generating means worn by the user or operated by the user generates a signal which is detected by detection means on the weapon to disengage the trigger interrupting means to permit the weapon to selectively be fired by an authorized user.
Abstract: A removable extension for a circular table saw comprising a pair of removable arms extending outwardly coaxially with the existing arms and an adapter for supporting the material to be cut which fits over the existing fence for the table saw.
Abstract: The invention briefly comprises apparatus for protecting the finish of a vehicle having a door along the side thereof comprising a wire rope detachably secured to the first end bumper on the vehicle and stretched through a center post trapped by the lip of the door between the opening in the door and spacing said wire rope from the side of the vehicle. A tensioning device is detachably secured to the second end of said wire rope to attach to the other bumper on the vehicle to form a rigid wire surface spaced from the vehicle to prevent objects from striking the vehicle.
Abstract: A device for illuminating a liquid drink for use at a party or a social event to give the appearance of an illuminated liquid. The device has a light adapted to colimate a beam of light through the transparent bottom of the glass receptacle into the liquid and be dispersed therein. Rechargeable or non-rechargeable batteries are secured within the base to act as a power source for the light. A switch means comprising of upwardly contacts to contact a conductive ring of the base of the glass receptacle forms the on or off means for the switch. A modified form would utilize a coaster which may be used with stem ware and would be activated by the weight of the glass upon the coaster. The still modified form would be formed by a manual operated switch which may be used with the light formed in a chamber formed in the box under the glassware. A charger base utilizing inductive principles is used to recharge rechargeable batteries if used in that particular embodiment.
Abstract: A battery tester for testing individual batteries on an electrically driven vehicle such that as the vehicle is in motion, the condition of each battery in a series connected power source maybe analyzed. The device briefly comprises indicator device such as the meter and connection devices to isolate individual battery to determine the voltage of each battery as the vehicle is being driven.
