Title: Compact pulsing pump for irrigation handpiece
Inventor: GRULKE DAVID H
IPC: A61C17/028
Filed: 1990-01-12
Abstract: COMPACT PULSING PUMP FOR IRRIGATION HANDPIECE    ABSTRACT OF THE DISCLOSURE A surgical pulsed irrigation handpiece comprises a pistol-like housing having a handle and a barrel extending forwardly from the top of the handle.  A finger actuable trigger is provided on the handle front edge.  An axially elongate pulsing pump extends longitudinally in the handle. An outlet tube extending from the top of the pump bends forwardly toward the front end of the barrel.  The trigger controls pulsed liquid outflow from the pulsing pump through outlet tube.  A preferred pulsing pump provides a piston axially slidable in a casing and a poppit axially slidable with respect to the piston.  A first spring urges the piston rearward in the casing.  A second spring urges the poppit forwardly with respect to the piston.  A pumped liquid chamber in the casing ahead of the piston responds to piston reciprocation to provide a pulsed liquid outflow. The poppit responds to both piston travel and gas pressure in a motor chamber to pop open a gas exhaust port to ter-minate an irrigant liquid pulse and return the piston to a starting position.

Title: Throttle holding device for better heater performance
Inventor: JENSEN LOUIS T
IPC: F02D11/02
Filed: 1990-02-12
Abstract: ABSTRACT OF THE DISCLOSURE         A throttle holding device is disclosed that allows an operator to hold open the throttle of the vehicle when the vehicle is not being driven.   This  increases  the amount  of  available heat  to  the heating system of  the vehicle cab and will allow the vehicle cab  to be more quickly and efficiently heated.  The throttle hold device of the present invention acts in conjunction with the parking brake and is actuated upon engagement  of  the  parking  brake  through  a  pneumatic  circuit.   Upon actuation a piston is moved against a spring bias and causes the throttle cord of the vehicle to further open the throttle thus raising the idle speed of the vehicle.  A shut-off switch is included on the pneumatic circuit to disconnect the system should the operator not desire that the higher idle be obtained.  The shut-off switch is particularly useful in the summer months or whenever it is more important to conserve gasoline than to adequately heat the vehicle cab.

Title: Fiber optical triangulation gage
Inventor: REDING BRUCE W
IPC: G01S17/46
Filed: 1990-05-10
Abstract: Abstract of the Disclosure Methods and apparatus for determining the curvature of a surface by use of multiple discrete triangulation sensors are described.  Robustness in the face of an extreme manufacturing environment is achieved by placing a triangulation light source and a detector at a remote, environmentally controlled location.  Light is relayed from the remote source to each sensor head by a single mode optical fiber, which then projects a spot onto the surface under consideration.  An image of the spot is formed in each sensor head, and is relayed back to the remote detector by a coherent bundle of fibers.  Range to the surface at each sensor head is inferred by the position of each image as relayed by the coherent bundles, while curvature of the surface is determined by comparing ranges as measured at each sensor head.  The optics contained in each sensor head are adapted to work well with specular, diffuse, opaque or transparent surfaces.

Abstract: Abstract of the Disclosure In an optical fiber ribbon fusion-splicing device, a TV camera is set such that the horizontal direction of an image sensor contained in the TV camera in which direction a horizontal scanning is carried out and the resolution of the image sensor is higher than that in the vertical direction in which a vertical scanning is carried out is a direction perpendicular to the coaxial direction of a pair of grooved supporting members for supporting fibers of a pair of optical fiber ribbons to be fusion-spliced. Thus, when the fibers of the pair of optical fiber ribbons are set on the supporting members in the coaxial direction thereof, the horizontal direc-tion of the image sensor is perpendicular to the coaxial direction of the fibers of the optical fiber ribbon. Since, therefore, misalignment of the fibers is involved in the high resolution direction, the misalignment can be detected with high precision, without decreasing the power factor of the image sensor.
