Title: The manufacture of signs
IPC: B44C1/16
Filed: 1978-09-21
Abstract: A method of making a sign is described which comprises taking a transfer material and a temporary support sheet, the transfer material comprising a transparent or translucent carrier sheet bearing on one side a plurality of transferable indicia, which are either sufficiently adhesive as such to enable their transfer to the support sheet or which bear a layer of adhesive on their face remote from the carrier sheet, or which are non adhesive but transferable by virtue of a coating of adhesive on the temporary support sheet, the adhesive if present being adapted to adhere the indicia to the temporary support sheet more strongly than they adhere to the carrier sheet, and wherein the material of the indicia is adhesive under the application of heat and pressure, transferring indicia from the transfer material to the temporary support sheet in the desired order to build up the desired legend for the sign, and applying the transferred indicia under heat and pressure to the surface of a transparent or translucent sheet, e.g. of acrylic plastics, to form the sign. After such transfer the indicia may be overcoated, e.g. with a contrasting colour background. The legend is read through the transparent or translucent sheet which protects it against abrasion or other damage.

Patent GB-2009472-A (GB)
Title: Method of and apparatus for checking signal generation for digital transmission system
IPC: H04B17/40
Filed: 1978-11-23
Abstract: In generating checking signals for locating faults in a digital transmission system, having a predetermined frame bit period length, by means of loop switching in intermediate regenerators of the system, a test signal is scrambled before transmission as are other signals for transmission in order to enhance the energy distribution in the transmitted signal. Problems then exist in generating an appropriate test signal by means of a multi-stage pseudo-random generator such that the test signal will be readily recoverable at the receiving end. A pseudo-random generator having a stages and a period of 2<a>-jbits is used to produce the test signal so that the checking signal period (with a predetermined scrambling mode) is equal to substantially a whole number of frame periods of the transmission system. The pseudo-random generator provides insertion of a frame code word into the test signal so as to avoid overlap with a loop closure command in the checking signal. <IMAGE>
Patent GB-2011141-A (GB)
Title: Temperature sensitive switching arrangements
IPC: G08B17/06
Filed: 1978-12-14
Abstract: A switch such as a thyristor Th or a triac is biassed by a voltage e.g. 350 mV or current which will not turn it on at a normal temperature. As temperature increases, the bias required to turn on a thyristor reduces, so eventually it turns on in response to its bias. Once on, the thyristor stays on unless current through it becomes less than the minimum holding current value. Simple threshold circuits in which the thyristor turns on at a set temperature are described as well as &cirf& a rate-of-rise sensitive circuit. <IMAGE>

Patent GB-2082701-A (GB)
Title: Brake slack-adjuster
IPC: F16D65/56
Filed: 1981-08-26
Abstract: A thrust-plate (11) transmits force to the discs of a multi-disc brake (not shown) via an adjustable force transmission bolt (41) of a telescopic two part plunger (14, 15). The need for adjustment is sensed by a known arrangement comprising a friction ring (21) which limits the retraction of an outer part of the plunger (14). After wear, the inner- part (15) of the plunger retracts further than the ring-limited outer-part (14). However, the parts are maintained in force-transmitting relationship by the follow-up motion of the bolt (41), which motion maintains the bolt (41) in frictional contact with part (14) via surfaces (23,24) and with part (15) via clutch surfaces on its helical thread (fig. 2, not shown). <IMAGE>

Title: Inserting needles into body spaces
IPC: A61B17/34
Filed: 1981-09-08
Abstract: An instrument for detecting penetration of the epidural space comprises a barrel 1 within which a plunger 2 is urged forward by a resilient strap 3. The barrel 1 has a nose 10 on which a Tuohy needle 12 is mounted. The inner surface of the barrel has a groove 13 that extends along the barrel, being spaced from the nose 10. In operation the assembly is pushed forward until the tip 13 of the needle 10 contacts the spinal ligaments. The plunger 2 is then pulled rearwardly past the end of the groove 13 so that air enters the barrel 1 and becomes trapped when the plunger is released and urged forwards by the strap 3. Penetration of the epidural space by the tip 13 of the needle 12 allows the trapped air to escape through the needle thereby providing an indication of penetration of the epidural space by causing the plunger to be moved forwards. <IMAGE>
