Abstract: 1,266,084. Lasers. WESTERN ELECTRIC CO. Inc. 10 June, 1970 [16 June, 1969], No. 28085/70. Headings H1C and H1K. [Also in Divisions C4 and G1] In a laser communications system, a semiconductor laser is operated under conditions of temperature and pumping energy such that self-induced spontaneous pulses occur in its output, and the pulse repetition frequency (PRF) is controlled by incident low power microwave energy. The equivalent circuit of Fig. 1 shows a PN junction laser 10 biased by a pumping source 11 which supplies a continuous current of 1À1-3 times the lasing threshold current. At temperatures of 77-110 K spontaneous pulses occur for GaAs diodes, and the PRF is locked on to microwave signals from a source 12. The lazer diode 10 forms the termination of a transmission line connected to the source 12, and the PRF varies according to information from a modulator 13 which controls the microwave frequency. Several lasers may be operated at the same basic PRF, Fig. 2 (not shown), each laser having a phase slightly different from the others to prevent the pulses overlapping. This forms the basis for a time multiplexed communications system, the receiver being a P-I-N or Schottky barrier photodiode or an array thereof. Laser having differing output frequencies may be used. The control of the PRF by microwaves is stated also to be applicable to electron beam or optically pumped semiconductor lasers.  Diode manufacture.-The N-type diode sub strate is a slice of Te doped GaAs having a free electron concentration of 3-4À5 x 10<SP>18</SP> electrons/cc. A P-type region is diffused into the substrate by the box method, a 2% solution of Zn in Ga saturated with GaAs acting as the source. A diffusion time of 4 hours at 800 C. forms a junction of 1À8 microns. The substrate is then covered with a protective SiO 2  layer and heated with pure As in a quartz ampoule at 850 C. for 4 hours before quenching to 0 C. Windows are then etched in the oxide covering the P-type side and the areas exposed are doped by a ZnAs source using the box method. Electrical contacts are applied to the doped regions, the contacts comprising 500  Ti, 5000  Ag and 1000  Au. The N-type side is then lapped to 105 microns and electrical contacts of 2000  Sn, 4000  Ni and 4000  Au applied. Scribing and cleaving forms individual Fabry-Perot cavities, and the finished laser comprises one of these mounted on a copper heat sink in a microwave package which is connected to a transmission line.

Abstract: 1288373 Valves TRIANGLE VALVE CO Ltd 15 Sept 1969 [24 Sept 1968] 45244/68 Heading F2V  In a sliding gate valve having two seating assemblies each comprised of an annular ring 16 which is disposed within a recess 18 and is spring-biased towards the gate, retention of the rings in their respective recesses is effected, when the valve is open, partially by the gate itself and partially by a formation on each of the recesses. At a location opposite to a slot (14, Fig. 1, not shown), into which the gate is retractable to open the valve, each recess has formed integrally therewith an arcuate lip 21 which co-operates with a corresponding rebate 23 in the ring 16 to so limit the inward movement of that part of the ring. In the fully open state of the valve, the terminal portion of the gate also serves to limit inward movement of each ring (Fig. 4, not shown). However, upon complete removal of the gate, those parts of each ring 16 which are not restrained by the lip 21 are spring urged into a position from which they can be readily removed from the valve via the gate slot (14). Each ring carries a P.T.F.E. seal 19 and a ring seal 20 and furthermore has an axial extension 25 which prevents foreign material entering behind the ring.

The clutch is re-engaged after engagement of the coupling. In a preferred embodiment, Fig. 1, a four way control valve 14 is set to supply fluid pressure via shuttle valve 30 to a single-acting ram 10 to disengage the clutch. At the same time fluid which may be air is supplied via a delay device 18 to double acting ram 12 to engage the coupling after disengagement of the clutch, Subsequently, since device 27 has a greater delay than 18, shuttle valve 24 is displaced to vent ram 10 to atmosphere through a further delay device 30 and the clutch re-engages under the action of a return spring. The coupling is disengaged by pressure applied along line 32 from a further setting of control valve 14. As a safety measure release of handbrake mechansim connected to valve 14 causes disengagement of the coupling via lines 32, 34. To ensure that the clutch is also disengaged as the coupling is disengaged the additional connections shown in dotted lines are made. In an alternative arrangement, Fig. 2, fluid is supplied from valve A via manifold B, line 3 and shuttle valve C to the ram E to thus disengage the clutch. At the same time fluid via delay device D is supplied to reposition the shuttle valve C to subsequently connect line 3 to ram G thus engaging the coupling. Clutch ram E is, at the same time vented to atmosphere via delay device H so that the clutch re-engages by its return spring. The coupling is disengaged via line 8. Emergency release buttons may be provided for releasing the coupling.
