Title: Electroluminescent Storage CRT Display Device and Operating Method
IPC: H01J29/10
Filed: 1980-04-25
Abstract: In a direct viewing electroluminescent storage CRT display system, an electron beam is used both to directly write and selectively erase information on an a.c. thin film EL panel that constitutes the CRT's storage target. The target consists of electrodes 42, 34, dielectric layers 40, 36 and an EL layer 38 consisting of material which exhibits voltage/luminance hysteresis. Writing and erasure of information are accomplished by scanning the beam over the rear surface of the target (which has an inherent memory characteristic), in synchronization with a train of alternating polarity pulses 44 that is applied across the electrodes. Information is written on the panel when it is addressed by the (pulsed) beam during the application of either a positive or negative pulse. Erasure occurs when the panel is addressed in the interval following the application of a positive pulse to the rear electrode. <IMAGE>

Title: Optical weighing
IPC: G01G3/12
Filed: 1980-06-05
Abstract: For weighing a succession of small items rapidly and accurately, each of a number of weigh members, moved in sequence in a continuous path, receives at one location an item 14 to be weighed and carries it to a weighing location on a member 13 which is movable in response to the weight of the item 14. The journey to the weighing location, while short, is sufficient to permit oscillation of the member 13 to substantially cease by the time it arrives at the weighing location where radiation from a laser 26 is impinged upon a boundary edge 15 of the member 13 and on a fixed edge 18. A resultant pattern of radiation 28, characterised by the displacement of the member 13 in response to the weight of the item 14, is scanned by a sensing system 27, the result being analysed by a micro-computer to give a measure of the weight of each successive item. <IMAGE>

Title: Force transducer with multiple measuring sections
IPC: G01L1/26
Filed: 1980-10-22
Abstract: A force transducer comprises a force receiver (22) connected to a fixed support (14) by at least two serially connected superimposed measuring sections constituted by for example pairs of flexure strips (10, 12 and 18, 20) with strain gauges (24, 26) provided for producing an electrical measure of the force (F) applied to the force receiver (22).

Title: Lift height control for a bandsaw
Inventor: TURNER P
IPC: B23D47/08
Filed: 1982-08-26
Abstract: A chain 6 is fastened to a side 8 of the frame 4 carrying the blade. The frame 4 swings about pivot 5 and is raised by means of ram 10. As the frame lowers onto a workpiece 3 chain 6 is drawn-off from a pulley 9.

Title: Method of determining corrosion properties of zirconium alloys
Inventor: CHENG BO-CHING
IPC: G01N33/20
Filed: 1982-12-15
Abstract: Means for discriminating the corrosion susceptibility of alloys of zirconium in an environment of a water cooled, nuclear fission reactor comprises the steps of: a) subjecting a specimen of an alloy of zirconium to an atmosphere of steam at a temperature of 300 to 420 DEG C for a period of at least 5 hours; b) thereupon subjecting the specimen of an alloy of zirconium to an atmosphere of steam at a temperature of 490 to 520 DEG C for a period of at least about 12 hours; and c) ascertaining any corrosion formation on said steam exposed specimen of alloy of zirconium. A weight increase of 300 to 400 milligrams per square decimeter or nodular corrosion covering more than 20 to 30% of the total surface area indicates that the alloy is susceptible to damaging corrosion.

Abstract: A shaft seal device is provided for inhibiting any fluid flow through between two relatively rotating members, for example, between a casing (3) and a rotary shaft (1) extending through the casing. A cylindrical seal ring member (11) made of elastomeric material is disposed between a rotary ring (5) fluidtightly fitted onto the rotating member (1) and a stationary ring (6) fluidtightly fitted into the stationary member (3) in such a manner that one end face thereof comes in contact with a face of the stationary member (3) and the other end or a progressive sealing ring 17 carried thereby comes into contact with the rotating member (1). The seal ring member has at least two annular grooves (12, 13) formed on its outer surface and ring-shaped resilient means (14, 15) are fitted into said annular grooves (12, 13) so that an axial force is produced in the seal ring member (11) under the influence of contractive force of the resilient means (14, 15) to bring the sealing faces into engagement and thereby ensure fluidtightness therebetween. The progressive seal ring (17) may be made of fluororesin and have a frusto-conical sealing face. The rotary ring 5 may be of a ceramic material. <IMAGE>

Title: Improvements relating to cable connectors
Inventor: DAVIES ROY WELLESLEY
IPC: H01R11/12
Filed: 1983-10-13
Abstract: A cable connector used to interconnect two cable portions 1 and 2 comprises separable portions 7, 16 and 14. The cables 1 and 2 are intended to connect a terminal of a car battery to electrical parts of the circuitry for operating parts of the car. The connecting member can be broken by separating two of the parts so as to isolate the battery. Separation is achieved by removing a spigot 15 or 18 from a respective slotted sleeve on the members 16 and 7. Removal of the intermediate link 16 prevents the cable connector from being interconnected as the spigot 15 is larger than the sleeve within the connecting member 7 and this can act as an anti-theft device. Conductive wires 5 of the cables are fixed to parts of the cable connector by screwthreaded members 8 pressing on olives 6. <IMAGE>
