This fixture holds the PC board on three sides and a quick acting cam clamp is actuated to retain and release a PC board. Another fixture is adapted to hold and retain a PC board that is warped or likely to warp. Vacuum is used with a plurality of standoffs to establish the desired holding plane of this PC board.

Abstract: A plastic heating tool unit is provided for cutting, sealing and like working of a relatively thin or film-like plastic element. The tool unit may function to sever a plastic element from a web and create firm thermal attachment thereof to another member. The tool unit includes an appropriately shaped annular or circular tool element formed of appropriate material which is responsive to an inductive field for self-generation of heat within the material. An annular radio frequency induction coil unit is coupled to the tool element. A heat transfer member is secured to the tool element and to a forced cooled heat sink which cools the transfer member and thereby the tool element. The transfer member creates a selected retarded cooling rate of the tool element to provide an improved interaction of the tool member and the plastic element and for more effective heating and cooling thereof.

Abstract: The present machine tool is constructed for an automatic tool exchange and includes a double column (11, 12) in which a spindle unit (15) and a tool magazine (22) are separately guided for moving jointly. A grapple claw mechanism includes an angular double claw. These features satisfy the hitherto contradictory requirements for a minimal idle time for the tool exchange and for a high machining accuracy by the elimination, among others, of the positioning tolerance.

Abstract: An electronic sensing device, operates to actuate a household lighting fixture in response to a sensed environmental condition such as sound or movement within a room. The device is provided with a receiver for sensing the particular environmental condition, a timer responsive to the output of the receiver, switching apparatus for switching on the household lighting fixture in response to the timer, and a power-providing circuit. The timer provides that the lighting fixture will remain on for a preselected time after sensing the environmental condition, and continually resets in the continued presence of the environmental condition. The switching apparatus switches the light fixture on in response to the timer output and further provides circuitry for varying the switched-on duty cycle of the lighting fixture in order to provide a dimmer control. The power-providing circuitry applies a portion of the leading edge of each half cycle of line current to power the circuitry of the sensing device.

The grid is preferably fabricated of metal wire, and the openings are square. Two grooves in the base open in opposite directions and accommodate two opposite edges of a grid opening. A bracket fits through one of the openings to mount the grid on a wall.

Abstract: The present crankshaft milling machine comprises at least one milling unit which may be controlled in its feed advance drive by a copying mechanism operating in synchronism with the rotation of the work piece. The copying mechanism is movable back and forth along a guide extending in parallel to the longitudinal axis of the work piece along a guide. The guide for the copying mechanism defines a plane which extends substantially vertically on one side of the work piece or crankshaft and in parallel to the crankshaft axis. Each milling unit is tiltably supported on a tilting axis located below the work piece axis and extending in parallel to the work piece axis. The feed advance drive is arranged on the side of the tilting axis facing away from the work piece. The feed advance drive reaches over the work piece, whereby a closed force flow around the work piece is established and the milling forces need not be introduced into the machine bed.

Abstract: A shear-fusion bond method is provided to create a direct fusion joinder or bond over an extended interface between like thermoplastic elastomeric elements of a block copolymer having a rubber-like center or mid-block and styrene end blocks. Such material has a high melt viscosity and does not readily flow. The interface surfaces are coupled to a heat source and heated to a fusion bonding temperature, thereby softening the interface material so that it flows under pressure. The elements, with the surfaces in pressurized engagement, are rotated relative to each other about an axis which is normal to the interface. Rotation is through an angle of at least 10 degrees to subject the softened interface material to a high rate shear force movement substantially in the plane of the interface. This decreases the viscosity and causes the interface material to bondably flow.
