Abstract: A method of monitoring the efficiency of a liquid pump (10) uses the temperature drop across the pump (10). Closely matching thermocouple junctions (13,14) of copper/constantan from the same respective alloy batches are bonded to suction and discharge conduits (11,12) using a low-viscosity "super-glue" to attain close thermal coupling. Each thermocouple junction (13,14) is thermally insulated by covering with a silicone rubber diaphragm (18) the rim of which is attached to the conduit by adhesive to enclose the junction in an air-tight pocket (17). Further thermal insulating and protective boxes (19) enclose the diaphragms (18). The thermocouple output is connected by copper wire to a thermally insulated voltage measuring instrument (16). The method produces useful accuracy for relatively low cost.

Abstract: A workpiece (W) transfer assembly (10) is provided for a progressive die type punch press. The assembly (10) includes a first crank bar (28) driven to oscillate about a first rock shaft (24) by the press ram, and a second crank bar (36) driven to oscillate about a second rock shaft (32) by the press ram. A horizontal linkage (40) extends between the first crank bar (28) and a workpiece engaging jaw (18). A vertical linkage (42) extends between the second crank bar (36) and the horizontal linkage (40). A linear bearing (48) interconnects the vertical linkage (42) and the horizontal linkage (40). A plate (44) having a vertically elongated slot (46) disposed therein is attached to the horizontal linkage (40). The first crank bar (28) extends through the slot (46) and thereby imparts motion to the jaw (18). The combination of elements allow horizontal jaw (18) movement into and out of engagement with the workpieces (W), and lost motion transmission in the vertical direction for raising and lowering the jaw (18) relative to the stations.

Abstract: The current limits of resolution of multi-element optical systems are exceeded by reducing the number of elements while introducing at the critical aperture a blazed transmission grating (60) having grating rings of low bending power defined by multiple plateaus. By illuminating the optical train with monochromatic light that constitutes a multiplicity of distributed sources having a substantial temporal coherence but spatial incoherence and by varying the slopes and widths of the grating rings, local phase delays are introduced that adjust aberrations in the optical system, providing an aligned composite wavefront. The system and method may be used for presenting an image, as for a wafer stepper, or for viewing an image, as in a microscope.

Abstract: The invention relates to a method and a device to restore a staircase. The restoration is effected with the aid of new tread elements (14) which are laid on top of the old steps (11, 12) and are fixed thereto with the aid of tread profiles. The cavities remaining between the old steps, the new tread elements and the profiles are filled with an assembly foam (18) which has a reaction time of several hours and during this time undergoes at most a twofold increase in volume. As a result, it is possible to foam the old steps, the profiles and optionally the tread elements in place, subsequently to assemble and align the different parts precisely, and finally to allow the assembly foam to harden. The tread profile (1) possesses three legs (2, 3, 4) arranged above one another and parallel to one another and a profiled part (6) connecting the latter, which is provided on its visible side with at least one receiving groove (9) intended to receive a cover layer (7). <IMAGE>

Title: A packet switch protocol and apparatus as for a parallel processing machine
Inventor: BRANTLEY WILLIAM CAIN JR
IPC: H04L13/08
Filed: 1989-07-08
Abstract: Packet switch protocol and circuitry for implementing it are disclosed. According to this protocol, a message transmitter of a first node in the network may send data through a data transmission link at a pre­determined rate until it is signalled, via a control signal generated by a message receiver in a second node, to suspend its transmissions. The message transmitter may also be signalled to resume trans­mitting data. The message receiver includes a buffer memory in which messages are temporarily stored if their selected path is blocked as they pass through the network. When the amount of available space in the buffer is less than a preprogrammed threshold value, the message receiver generates the control signal to suspend message transmission. This threshold value leaves sufficient space in the buffer to store any data which may be in the pipeline between the transmitter and the receiver. When the amount of available space rises above this threshold, the message receiver indicates to the transmitter to resume transmission. A message spanning an interface during transmission may be suspended without losing spatial contiguousness. The message transmitter also transmits a signal which marks the last portion of a message. This signal is stored in the buffer with the message data and is used to delimit messages in the buffer, allowing multiple messages to be stored in one buffer without extra delimiting values.

IPC: B29C45/28
Filed: 1989-07-31
Abstract: A valve gated injection molding system having a double acting pneumatic rack and pinon valve pin actuating mechanism. The melt passage branches in a manifold (14) from a central inlet (12) and flows along the valve pin (28) in a central bore (16) in the nozzle (18) to the gate (20). A pneumatically driven piston (96) pivots a toothed pinion member (84) mounted in a slot (74) in the manifold (14). The pinion member (84) engages a toothed rack member (76) which reciprocates along a straight line in the slot (74) in the manifold and engages an enlarged head (66) of the valve pin (28) in a slot in the rack member (76). Lateral forces from the pinion member (84) are absorbed by sliding contact of surfaces of the rack member (76) against matching surfaces of the slot (74) and/or a valve pin bushing (26), and are not transmitted to the valve pin (28). This avoids uneven wear and buildup of melt deposits around the valve pin which can otherwise result in leakage and malfunction.

Abstract: This invention relates to photosensitive compounds that generate free radicals upon exposure to light. 
     Halomethyl-1,3,5-triazines are known to be initiators for a number of photochemical reactions. An activator is a compound which, in the presence of a photoinitiator, is not significantly directly excited by activating radiation, but instead forms a free radical in response to the exposure of the photoinitator. It would be desirable to combine a photoinitiator as an activator within the same molecule. 
     This invention provides a radiation-sensitive organo-halogen compounds having a photo-labile halomethyl-1,3,5-triazine moiety and at least one amine-containing moiety within one molecule. The compounds serve the dual purpose of photoinitiation and polymerization acceleration, thereby eliminating the need for the use of two separate compounds. The compounds of this invention are good photoinitiators, and compositions containing them are useful in printing, duplicating, copying, and other imaging systems.

Abstract: The simulated engine characteristic control system for transmission transient performance tests for automotive vehicles comprises a motor (2) for driving an input shaft of the tested transmission (1). A pick-up (5) detects revolution of the motor. A simulating circuit (not shown) simulates either an opening angle (O) of the throttle of the engine to be associated with the tested transmission or the intake manifold pressure of the engine. An engine characteristic generator (4) generates a torque command signal (T*) according to predetermined engine revolution/torque characteristic curves, in response to the signals (N,ϑ) from the pick-up (5) and the simulating circuit. A torque/current transducer (11) transduces the torque command signal (T*) to an analog current command signal (I₁) according to a predetermined torque/current characteristic. Means (12,16) are provided for compensating the current command signal (I₁) in consideration of a torque component occurring at an axial moment of inertia of the rotating member of the motor (2) during acceleration or deceleration of the motor, and a field characteristic of a field coil of the motor, representing the output torque/revolution of the motor. The motor (2) is drivingly controlled in response to a current command signal (I*) compensated through the compensating means (12,16).
