Abstract: 1536405 Touch responsive switching systems TEXAS INSTRUMENTS Ltd 18 Dec 1975 51854/75 Heading G1N [Also in Division H2]  A switching system for controlling the current flowing in a load 1 from an A.C. source comprises a gated semi-conductor switch e.g. a triac 4 connected in series with the load, gating signals for the triac being developed by a control circuit which includes a plurality of touch plates 33. Pulses are developed in a transformer 10 whenever the A.C. source voltage passes through zero such pulses being transmitted to a further transformer 9 to gate the triac 4 whenever a transistor 22 is conductive. Assuming the transistor 22 to be non-conductive and a transistor 27 in a bi-stable flip-flop conductive the load 1 will be de-energized. A touch on one of the plates 33 will cause a field effect transistor 28 is momentarily switched off thus causing a transistor 29 to be switched on whereby a negative going pulse to be generated which is applied to the flip-flop causing it to change state. Transistor 27 thus becomes non-conductive, transistor 22 becomes conductive to gate the triac 4 and the load is energized. A further touch on one of the plates 33 acts in a similar manner to again change the state of the flip-flop so de-energizing the load. Leakage injection for the touch plates 33 is provided by way of a resistor 21 which is made adjustable to suit the length of the inter-connecting leads for the touch plate system.

Title: Improvements in or relating to sealing rings
Inventor: THOMAS ROBERT VICTOR
IPC: F16J9/28
Filed: 1968-11-07
Abstract: 1293906 Piston rings; shaft seals WELLWORTHY Ltd 5 Nov 1969 [7 Nov 1968] 52842/68 Headings F2B and F2T [Also in Division C3] Sealing rings are made from a length of synthetic plastics material which has a cross-section generally corresponding to that of the rings, is wound around a mandrel a plurality of times to form a helix and then cut to form separate rings, the plastics material being treated to retain its ring shape. In the embodiment shown in Fig. 1 for making a split piston-ring, granulated or powdered, filled or unfilled, P.T.F.E. 1 is compressed and sintered in a press 2 prior to extrusion by a ram 3, the P.T.F.E. being heated by heaters 4. The P.T.F.E. is continuously extruded through a die 5 to form a bar 6 which is coiled whilst still hot around a mandrel 7. After cooling, the coiled P.T.F.E. bar is cut by a cutter 8 so that separate rings are formed by each coil 6a, 6b &c. The external surface of the coiled bar may be machined to the finished size before or after cutting. Instead of coiling the bar 6 around the mandrel 7 whilst still hot it may be allowed to cool and, before or after reheating, coiled around the mandrel and then heat treated, e.g. by induction heating the mandrel by a fluidized heating medium, so that the rings retain their form when cut and removed from the mandrel. To form a circumferentially continuous ring, a split-ring 11, produced as previously described, is inserted in an outer metal ring 12 and urged outwardly by an inner split-metal ring 13. The P.T.F.E. ring 11 is then heated to a temperature between 200‹ and 390‹ C. to cause it to plasticize and expand so that its free ends 15 abut and weld together. The ring is then cooled rapidly and removed from the rings 12 and 13. In a further embodiment, a bar of extruded P.T.F.E. is wound when cold to an undersize diameter and then cut, the undersize diameter being selected so that the ring after cutting tends to pause during opening at the desired finished ring diameter. In another embodiment, the rings may be formed from strips cut from a sheet of extruded P.T.F.E. The P.T.F.E. bar may incorporate a core of springy material. The invention may be applied to spiral or helical seals and may be used for sealing between relatively reciprocable and/or rotatable members.

Title: Optical data transmission system
IPC: H01S3/081
Filed: 1972-11-20
Abstract: 1399908 Lasers RCA CORPORATION 20 Nov 1972 [22 Nov 1971 (2)] 53453/72 Heading H1C The resonator of a mode-locked laser contains an active medium 106, Fig. 1, a polarizer 104 such as a Glan or Wollaston prism, and a polarization shifter 114 controlled from a data source 118, the polarizer causing the resonator to support radiation of one linear polarization P 1  only, and any radiation of an orthogonal linear polarization P 2  being deflected by the polarizer out of the resonator along an upward path if directed towards the polarizer from one resonator mirror 100 and deflected along a downward path if directed from the other resonator mirror 102. Mode locking is produced by a phase modulator 112 consisting of an electro-optic crystal, an acousto-optic element, or a signal responsive absorber, controlled by a periodic signal generator 116 operative at a mode-locking frequency NC/21, where l is the reflector spacing. The data source 118 is binary and is synchronized with the signal generator to control the polarization shifter 114 which may be an electro-optic crystal. The shifter 114 changes incident radiation from the active medium into two linearly polarized and orthogonal components P1 and P2, and by arranging the shifter to normally delay P2 relative to P1 by an integral number of wavelengths in the double pass of radiation through the shifter, only linearly polarized radiation P1 passes through the phase modulator 112 to the polarizer 104 in the absence of data input. When, however, a data bit representing a binary one is applied to the shifter from the source 118, the phase delay is changed and the polarizer receives both components P1 and P2 of which P2 is deflected out of the resonator along a downward output path. In a modification, Fig. 1a (not shown), a single D.C. biased electrooptic crystal effects both mode locking and polarization shifting. A second resonator may be formed by providing a further reflector 330, Fig. 3, in the upward path from the polarizer 304, the two resonators formed by reflectors 300, 302 and 300, 330 supporting the linear and orthogonal polarizations P1 and P2, respectively. Each resonator includes a modulator 310, 332 consisting of a phase modulator 112 and a polarization shifter 114 as in Fig. 1, which are controlled by a mode locking source 316 and a binary data source 318. With this arrangement two outputs are produced, in a common path, each separately modulated by respective data, one output being in the linear polarization mode P1 and the other in the othogonal linear polarization mode P2. In a modification of Fig. 3, Fig. 4 (not shown) the mode locking control is omitted and the data input is analogue. The laser active medium may be Nd.YAG.

Abstract: 1286955 Signal discriminators UNITED KINGDOM ATOMIC ENERGY AUTHORITY 12 Nov 1969 [12 Nov 1968] 53522/68 Heading H3T A level discriminator for providing outputs 21, 22 such as to enable discrimination of a signal of amplitude between low and high levels from signals of amplitudes outside these limits has two comparators 17, 18 for comparing an input signal 19 with two derived reference potentials (at R11, R12) defining the high and low levels, the two derived reference potentials are produced from two basic reference potentials RV1, RV2 by two amplifiers 13, 15 one of which 15 is connectable to subtract the basic reference potentials and the other of which 13 is connectable to add the basic reference potentials. The amplifiers 13 and 15 have feedback so as to operate as unity gain summing and subtracting amplifiers. With the switches S1A and S1B as shown adjustment of RV1 moves the centre threshold (C, Fig. 2, not shown), and adjustment of RV2 symmetrically expands the channel or threshold range by increasing the upper threshold and decreasing the lower threshold. With the ganged switches in position 2 asymmetric channel mode is obtained (Fig. 3, not shown), in which the low level threshold is set by RV1 and the channel width is set by RV2 which independently adjusts the high level. In the position 3 of these switches both the high and low level thresholds are adjustable independently by RV2 and RV1. A detector circuit (not shown) senses when the high level threshold is exceeded and when the low level threshold goes through zero and is arranged to provide a visual warning that the unit is operating outside the permissible range and also to inhibit output signals from the unit. The basic reference potentials from RV1, RV2 are obtained from a stabilized reference supply at 11.
