Abstract: Individual parts, such as glass fibres (41, 42) are connected by means of memory-shape alloy connection elements (20); a, for example, sheet- or plate-shaped body (10, 20, 51) with at least one virtually cylindrical perforation (30), is used as the connection element, the perforation running approximately perpendicular to the surfaces of the body (10, 20); the smallest dimension of the surfaces of the body is greater by a multiple than the diameter of the perforations. The bodies (10) are deformed (20) at (T) Mf, into the major plane, under two-axis expansion, and at (T) Af they spring back approximately into the shape (51) before deformation. The individual parts (41, 42) are inserted in the perforations (30) at (T) Mf and are held in a force- fit in the connection (51) by the springing back of the bodies (20) into their original form (10, 51) at (T) Af. <IMAGE>

Abstract: A multiported memory module (11) permits memory access by a plurality of requestors (10) via requestor ports (13a, 13b; 16a, 16b) and has a priority circuit 100 for determining priority of access requests. A status register (21) within the memory module (11) stores lock-out values to control the communication between the memory module (11) and the requestors (10). The status register (21) may be written into or read from by the requestors (10). Each bit position (305 to 312) of the status register (211) is dedicated to a corresponding requestor port (13a, 13b; 16a 16b). If a bit position represented by a flip-flop (305 to 312) contains a binary zero, the corresponding requestor port (13a, 13b; 16a, 16b) operates normally, but if it contains a binary one, disabled gating means (411 to418) prevent the memory module (11) from honouring an access requests via the corresponding requestor port. Thus one or more of the requestors (10) may be locked out in response to software instructions.

Abstract: High concentration polymer slurries contain up to 60 weight % to 75 weight % xanthan gum in a solvent base treated with suspending agents, dispersants, and thinning agents. Mineral oil, diesel oil, kerosene, alcohols (six to twelve carbons), vegetable oil, ester-alcohols, polyol ethers, and the like may be used as the solvent. The preferred suspending agent is either an organophilic clay or hydroxypropyl cellulose. The preferred dispersant is either an ethoxylated linear alcohol or a fatty acid ester of vegetable , oil or aminal oil. The preferred thinning agent is lecithin. These slurries greatly improve the dispersibility of xanthan gum or any other hydrophilic colloid, such as guar, hydroxypropyl guar, cellulosics, polyacrylamides, and the like.

Abstract: Hospital patient temperatures are monitored by providing each patient with a battery powered transmitter (10) containing a thermistor (48) and reference resistor which is positioned over the patient's carotid artery. A receiver (20), carried by a nurse, includes an actuator (24, 26, 28) for closing a reed switch in a transmitter near which it is positioned to activate that transmitter. Upon actuation of the transmitter, the patient's temperature varies the duty cycle of a high frequency transmitter output. The outputs of a number of transmitters, each associated with a different patient are elicited, one by one, and monitored by the receiver (20) which contains a demodulator connected to a microprocessor coupled to a visual display (30). The microprocessor calculates patient temperature selectively in Fahrenheit and Celsius conventions. The microprocessor also detects low battery condition in the transmitter. The receiver (20) includes a self-calibration test and low battery indication circuits.

Abstract: The invention relates to a method for making decorative emblems, plaques, and panels, having an ultrathin coating of plastics material. 
     In one embodiment, the coating is provided by flow coating a clear, fluent plastics material onto the surface of a decorated substrate (31). The coated substrate is then pressed between surfaces of a pressure fixture (12) to produce the ultrathin coating. The upper surface (28) of the pressure fixture is smooth and does not stick to the plastics material so that no imperfections are introduced into the finished coating. After curing, the coated substrate is then formed by cutting and trimming operations into a finished emblem, plaque, or panel.

Inventor: SICKLER KENNETH HAROLD
IPC: F16K17/04
Filed: 1980-11-06
Abstract: Pressure relief apparatus for an internal combustion engine compression relief enginge brake is disclosed. Normally an existing pushrod (74) is used to drive a master piston (66) which in turn controls the motion of a slave piston (50) which opens an enginge exhaust valve (60). The problem of assigning such additional function to the pushrod is that an increased load may be experienced which may exceed the design capacity of the pushrod. The invention solves this problem by providing a bi-stable relief valve (106 in figures 2 and 3) located in a high pressure hydraulic fluid circuit which interconnects the slave and master pistons together with damping means (112 or 122 in figures 2 and 3) adapted to damp out rapidly the oscillations of the valve during the period of its opening so as to maximize the flow of hydraulic fluid through the bi-stable valve and minimize the time required to relieve the pressure in the high pressure hydraulic system of the compression relief engine brake. The damping means comprise a spring controlled valve guide (116 or 125 in figures 2 and 3) which inhibits premature reseating of the bi-stable valve and maximizes the average opening of the valve during its operating period.

These rail holders are provided at their attachment or fastening side with at least two respective centering protuberances or nubs or the like which engage into corresponding centering openings provided in the side plates to which the rail holders are fastened. The rail holders possess, at their rail contact side, a dovetail clamping device which, in cooperation with a dovetail profile or section extending along the underside of the travel rail or track, to reliably and easily releasably holds the travel rails and the rail holders by virtue of a clamping action which is exerted at all sides of the dovetail profile. The side plates, and, in particular, the position of their centering openings are produced true or exact to size and with narrow tolerances so that in cooperation with the related centering protuberances and the rigid dovetail clamping there is automatically ensured parallelism and alignment of the travel rails or tracks required for a quiet escalator or stair running. The guiding apparatus can be assembled without the need to resort to assembly fixtures or jigs and without subsequent adjustment from individual mass-produced parts.
