Title: Positioning Device for a Rubber-Blanket Cylinder
Inventor: THUENKER NORBERT
IPC: B41F13/28
Filed: 1996-03-26
Abstract: The invention relates to a positioning device for a rubber-blanket cylinder (1) held in doubly eccentric bearing arrangements (8, 8'), said rubber-blanket cylinder (1) cooperating with a plate cylinder (2) and an impression cylinder (3) of a printing unit of an offset printing press each with location-fixed rotation axes (4 and 5).

Title: Electrostatic discharge protection circuit
Inventor: WAGNER GLEN R
IPC: H01L27/04
Filed: 1994-08-16
Abstract: A device for protecting an integrated circuit (IC) against electrostatic discharge (ESD) includes a self-triggered silicon controlled rectifier (STSCR) coupled across the internal supply potentials (Vcc, Vss) of the integrated circuit.  The STSCR exhibits a snap-back in its current versus voltage characteristic which is triggered at a predetermined voltage during an ESD event.  As large voltages build up across the chip capacitance, the predetermined voltage of the SCR (30) is triggered at a potential which is sufficiently low to protect the internal junctions of the IC from destructive reverse breakdown.  The STSCR comprises a pnpn semiconductor structure which includes an n-well disposed in a p-substrate.  A first n+ region (62) and p-type region (64) are both disposed in the n-well (60).  The n+ and p-type regions are spaced apart and electrically connected to form the anode of the SCR.   The ESD protection device also includes diode clamps (26, 27) between the periphery and internal power supply lines, and a novel well resistor which provides a distributed resistance further protecting sensitive output buffer circuitry.

IPC: A61K6/838
Filed: 1995-10-31
Abstract: Methods for producing a room temperature stable, phase pure .alpha.-C3P  product, and compositions derived therefrom, are provided. In the subject method, a tricalcium phosphate source is heated to a temperature sufficient to convert substantially all of said tricalcium phosphate source to a substantially phase pure .alpha.-C3P product. The temperature of the resultant product is rapidly cooled to a temperature below about 700 ~C, resulting in a room temperature stable, reactive .alpha.-C3P product. The resultant .alpha.-C3P product may be milled to provide an .alpha.-C3P composition which may find use in the preparation of calcium phosphate cements.

Title: Finger angle adjustment of a pickup reel of a crop harvesting header
Inventor: TALBOT FRANCOIS
IPC: A01D57/03
Filed: 1996-07-05
Abstract: A crop harvesting header includes a reel mounted on a pair of forwardly extending arms carried on a header frame above a table and cutting knife. The reel is rotatable about a longitudinal axis and includes bats with fingers which pivot each about a respective bat axis so the angle of the fingers varies as the reel rotates. The angle of the fingers can be varied to increase and decrease the angle at the knife. The arms include a forward portion which is arranged at an angle to a main portion so as to be inclined downwardly and forwardly therefrom. As the reel supports on the arms is moved forwardly along the arms and engages onto the forward portion, the reel is moved downwardly and forwardly which simultaneously changes the angle to provide a more aggressive action as the reel is moved forwardly of the knife.

Patent CA-2184313-A1 (CA)
Inventor: DOSMANN ANDREW
IPC: G01N21/47
Filed: 1996-08-28
Abstract: A diffused light reflectance readhead is disclosed. The readhead employs an improved light emitting diode (LED) providing a more strongly collimated beam of light around a beam axis onto a reagent test pad. The reagent test pad is supported on a strip guide at an angle .alpha. of 5 degrees with respect to the perpendicular of the beam axis. It has been discovered that when .alpha. is between 3 and 8 degrees that specular reflection is dramatically reduced in relation to the small reduction in reflected light received by a sensor. The diffuse reflected light travels to the sensor by passing through a staircase optical baffle at an angle of 45 degrees to the perpendicular of the beam axis. The sensor converts the optical signal into an electrical one for processing and analysis. One embodiment of the present invention can detect the presence of glucose in a blood sample.

Abstract: An apparatus (40, 50, 60) and method (100, 101, 102, 104, 106, 108, 108a, 109, 110) for directing the operations of multiple geography-altering machines (14) on a common work site (12) relative to one another. Position information from several machines (14) is shared to generate a common, dynamically-updated site database (66) showing the machines' relative positions and site progress in real time. The common site database (66) is used to direct the operation of one machine (14) with respect to another machine or machines (14) for example by generating an operator display (22) of the site (12) showing relative machine position and total machine work on the site (12). The operator can accordingly adjust the machine's operation to avoid interference with other machines (14) or unnecessary overlap of work on the site (12). The information can also be used to coordinate the operations of several machines (14) in complementary fashion Machine position information can be broadcast from the machines (14) to the site database (66) to create a common, dynamically-updated database (66) which is then shared with one or mote of the machines (14). In a particular embodiment each machine (14) is provided with its own dynamically-updated database (66) and operator display (22), and machine position information is shared on a continuous, real-time basis between the machines (14) so that they effectively share a common site database (66).

Inventor: OHKAWA HIROYASU
IPC: G01S5/18
Filed: 1996-09-23
Abstract: A system for generating three-dimensional position data is so adapted as to make it comparatively easy to obtain accurate three-dimensional data representing the three-dimensional coordinates of one or a plurality of measurement points.  Ultrasonic transmitters are deployed at a plurality of measurement points on an object of interest and ultrasonic receivers are deployed at the apices of a frame surrounding the object.          Ultrasonic waves are emitted from one of the ultrasonic transmitters and a counter starts counting from the moment ultrasonic waves are transmitted.  When the ultrasonic receivers receive the emitted ultrasonic waves, the count data in the counter are latched in corresponding latch circuits.  The data that have been latched in these latch circuits are accepted by a controller/processor, which computes three-dimensional coordinate data of the measurement point based upon these items of latched data.
