Title: Drill grinding machine
Inventor: SCHROEDER RICHARD
IPC: B24B3/26
Filed: 1991-04-19
Abstract: A drill grinding machine employs independent servo motors for drill rotation, drill lift, and drill feed which are connected through respective drive mechanisms to a tubular spindle that is rotatably mounted within a work head. The work head contains a hydraulic clamp for selectively chucking and releasing a drill holder in which a drill is gripped such that the drill point is proximate a grinding wheel. The drill rotation, lift and feed motors are actuated to rotate the drill about its longitudinal axis and to move the drill point along a predetermined cyclical path of contact with the grinding wheel to grind a selected point. Combinations of points may be ground on a single drill by suitably controlling the lift and feed motors. A timing pad adjustably mounted to the machine housing cooperates with the lift and feed motors and the work head clamp to enable the drill to be manually timed prior to a grinding cycle. Drill rock is selectively available through spring loaded contact between the work head and a hardened strip that is rotatably mounted in the machine housing. <IMAGE>

Title: Insulated lampholder pin
Inventor: CHAMBERLAIN STEPHEN WILLIAM
IPC: H01R33/46
Filed: 1995-11-06
Abstract: Two insulated lampholder pins are mounted in an existing type of bayonet lampholder. The pins are designed to be electrically disconnected until a bulb is installed into the lampholder. Each pin has an electrically conducting outer body to which a wire is screw attached and a spring-urged metal Y and insulating X inner body. When a bulb is absent, the outer body makes contact with the insulating part of the inner body at point X and hence the metal end Y of the inner body is isolated. An inserted lamp pushes the inner body against the spring so that the outer body contacts the inner body at point Y to interconnect it with the cable. The spring pressure would be such that it would allow a lamp to be inserted into the lampholder but would be too great as to allow a finger to push the pin in.
