Abstract: PAINT CAN AND BRUSH RECEPTACLE             Abstract of the Disclosure A receptacle for a paint can and brushes is mounted for quick release to a support bracket, which in turn is pivotally attached to a clamping bracket, adapted to be clamped to the side rail of the ladder.  The pivotal attachment between the ladder clamping bracket and the receptacle support bracket insures that the paint can remains level regardless of ladder inclination.  In addition, the brush well is conveniently posi-tioned between the paint can support housing and the clamping mechanism to provide a depository for brushes when not in use.          A passageway between the brush well and the paint can housing allows excess paint to drip back into the housing and, because of the construction of the bottom wall of the paint can housing, be kept out of contact with the bottom of the paint can.

Abstract: ABSTRACT OF THE DISCLOSURE A programmable manipulator apparatus employs a memory for storing digital representations corresponding to different position of the programmable manipulator in a number of different axes, The manipulator apparatus in-cludes encoders for developing position signals representing the position of the manipulator in each of the axes. During repetitive work cycles, the stored digital signals in the memory are utilized as command signals and are compared with the encoder signals to move the manipulator to each set of positions in sequence corresponding to the various recorded position as they appear in the memory.         A program modification apparatus is provided to modify or steps during the repetitive work cycles. The operator selects the program steps to be modified along with the desired positional modifications of the manipulator both determined by his observations and/or results of the work cycle.

Abstract: ABSTRACT OF THE DISCLOSURE      A high voltage type photoflash lamp filled with a filamentary combustible material and oxygen and having a beadless ignition structure comprising a pair of spaced apart lead-in wires with spherically shaped terminations, a glass frit coating over the lead-in wires with scraped-off portions exposing the bare metal of the wire adjacent each termination, and a coating of primer material over the frit-coated terminations and bared portions of the wires.  The primer may bridge the wire terminations or comprise separate spaced apart coatings on the respective terminations, with the filamentary combustible being in contact with both terminations to provide a conducting path therebetween.  The frit coating is thick enough to prevent preignition short circuits. Also disclosed is a method of making the lamp including the steps of applying a flame to melt down the ends of the lead-in wires to provide smooth and rounded terminations, dipping the wires in a liquid suspension of glass frit, air drying, passing a blade between the wires to scrape away portions of the frit coating and expose bare wire adjacent the terminations, sealing the lead-in wires into one end of a length of glass tubing, dipping the coated lead-in wires into a primer cup to provide a coat of primer over the terminations and scraped portions, and then finishing the lamp.

Abstract: DEPTH-OF-CUT MECHANISM FOR ROUTERS                 ABSTRACT OF THE DISCLOSURE    A portable electric router comprising a base having a dust chamber formed below a motor mounted to the base to be axially adjustable therein. A pair of handles are connected to the base with a passage formed in one of the handles in communication with the dust chamber.  A blower is formed on the top side of the motor with the router connected to and driven by an extension from the motor armature shaft.  A flexible conduit interconnects the handle passage and the blower, and a dust bag collects the dust and debris from the blower discharge.  The con-duit which interconnects the handle and blower is flexi-ble to permit axial adjustment of the motor within tile base.    The motor is journaled in a housing the lower half of which is threaded to receive an internally threaded ring member having outer and inner rings.  The outer ring has a flat bottom which sits upon an annular flange formed at the top of the base.  Rotation of the outer ring will raise or lower the motor housing to adjust the depth-of-cut.       The inner ring is rotatably mounted in the outer ring and is calibrated to correspond to the vertical adjustment of the router bit.  A pointer is cast on the base to permit the inner ring to be set to zero prior to rotation of the outer ring to the desired depth-of-cut dimension.  A base clamp secures the motor housing within the base at the adjusted position.

Abstract: ROTARY ATOMIZATION MEANS FOR THE PRODUCTION OF METAL POWDER                        ABSTRACT           A rotary liquid metal atomizer is positioned to receive a stream of molten metal on the top thereof.  The atomizer is formed as a hollow disc means having a concave top surface and mounted for rotation at high R. P. M.'s on the top of a hollow drive shaft.  A circular coolant baffle is located in the hollow disc means, for cooling fluid to flow around, and is mounted on the top of an inlet cooling tube located within the drive shaft.  Cooling fluid is directed through the inlet cooling tube to the top of the water baffle where it flows through a hole in the center thereof and around the space between the baffle and the interior of the hollow disc means and down between the inlet cooling tube and drive shaft.  The top of the disc means over the coolant baffle is formed of copper.  A metal rim is placed around the upper outer periphery of the copper disc forming a recessed center portion. A ceramic coating is placed in the recessed portion with its outer edge against the inside of the rim.  The metal rim acts to hold the coating against centrifugal force and to provide a material for the liquid metal to melt and form a fusion weld therewith to firmly attach a controlled solidified metal skull to the atomizer.
