Title: Improvements in or relating to riveting
IPC: B21J15/10
Filed: 1937-08-06
Abstract: 498,059. Riveting; punching. CONSOLIDATED PNEUMATIC TOOL CO., Ltd., and WILLIAMS, C. V. Aug. 6, 1937. Nos. 21705/37 and 9329/38. [Class 83 (iv)] In a method of riveting together two or more pieces of thin metal, the rivet itself is used as a cutting tool and the metal cut out by the rivet is blown away by compressed air. The apparatus for carrying out the method comprises a yoke e provided at the bottom with a cup-shaped abutment f and spring actuated jaws h for holding the rivet and at the top with a compressed air nozzle s and a slidable bush m within which is mounted a set k surrounded at its lower end by a die l comprising two semicircular sleeves secured to the set by a cross-pin w. In operation, one part to be riveted is drilled to serve as a template and the parts r are together placed over a rivet as shown in Fig. 3. The set k is then moved downwardly by means of a lever c and a roller b operated by compressed air entering a chamber a. At first the die l bears on the metal and presses it down over the shank of the rivet ,g held in an adjustably mounted dolly f. At this stage the nozzle s has been depressed by the lever c so that its inlet t communicates with an auxiliary compressed air line u and the piece of metal punched out by the rivet is removed by a blast through a transverse passage q in the die. The set k then descends further and forms the protruding shank of the rivet into a head, the two sleeves of the die separating to allow the passage of the set.

Title: Improvements in or relating to light emitting transistor systems
IPC: H01S5/30
Filed: 1964-05-26
Abstract: <PICT:1062202/C4-C5/1> An inter metallic compound junction transistor with a thin (<\>tl m ) base region, and consequently a high "b ," is used as a light source. For such use a control signal current applied, as shown in Fig. 1, across the emitter base junction 14 causes an amplified current across the base collector junction 15 of sufficient strength to produce visible or infra-red radiation, which may be transmitted through a glass "light-pipe" 26.  The transistor of Fig.1 comprises a gallium arsenide or gallium arseno-phosphide body of N conductivity with alloyed or diffused zincdoped emitter and collector regions 12,13. Except where the electrodes 16,18,20 and the light-pipe 26 are attached, the surface of the semi-conductor is covered by an insulating layer 19 which may consist of a silicon dioxide film surmounted by a glaze produced by the method of Specifications 992,044 and 994,814. Figs. 2 and 3 (not shown) depict modifications. The transistor of Fig. 3 is a planar transistor whose body (the collector region 13) of telluriumdoped gallium arsenide has been further doped with zinc to form a base region (11) and subsequently with sulphur, selenium or tellurium to form an emitter region (12), using a silicon masking technique as disclosed in Specification 1,052,379. The device is completed by an insulating coating 19, as in Fig. 1, and the collector region may (as in Fig. 3) but need not (as in Fig. 2) be etched away on the lightemitting side to provide a short optical path between the base-collector junction (15) and a transparent, e.g. glass, window (30) through which the light emerges.  The associated circuitry for producing light is as shown in Fig. 1, but with the control signal and bias potential of opposite polarity. missing page 150

IPC: G06F7/38
Filed: 1963-05-31
Abstract: 1,094,263. Transistor blocking oscillators. ENGLISH ELECTRIC CO. Ltd. May 29, 1964 [May 31, 1963], No. 21917/63. Heading H3T. A monostable blocking oscillator comprises a transistor 10 having regenerative feedback via a transformer 15, the load being connected in series with the secondary winding so that the pulse duration is independent of the load impedance. As described, the circuit is triggered by a short-duration pulse at 22 which drives transistor 10 into saturation giving a linear rise in collector current, controlled by inductor 14 and which continues until transistor 10 is no longer saturated when it becomes rapidly turned off by regenerative feedback by transformer 15. The constant voltage developed across the secondary of transformer 15 during the pulse is more than sufficient to keep the transistor saturated. Any load current taken from terminal 20 causes a corresponding increase in the primary current of transformer 15 which would tend to advance the instant at which transistor 10 becomes unsaturated. The load current in emitter resistor 11, however, allows the collector current to rise to a higher limiting value so as to compensate for the effect of the load current. A short-duration output pulse is obtained by differentiating at 16, the leading edge of the collector current pulse.

Abstract: 795,500. Refrigerating. RUHRGAS AKT.- GAS. July 19, 1956 [July 20, 1955], No. 22398/56. Class 29 [Also in Groups XXVI and XXVIII] To recover energy from heat freed during the cooling of gases compressed in one or more stages, a vapour employed as cooling means in heat exchangers arranged subsequent to the compression stages is superheated in the heat exchangers and conveyed to an expansion machine. The heavy line indicates the course of the compressed gas, i.e. it passes through the first compression stage 1, is cooled in the heat exchanger 1a, passes through compressor 2 and is cooled in heat exchanger 2a, is further cooled in deep-cooler 3 and then heated in precooler 10 where it cools the compressed gas being fed to the deepcooler. The cooling means (CF2Cl2, carbondioxide, propane, isobutane, or ethane) passes at a pressure above the critical pressure from the pump 4 into the heat exchangers 1a and 2a where it is evaporated and highly superheated, performs work in the expansion machine 5, is liquified in the water-cooled condenser 6 and returns to pump 4. A portion of the condensate passes through a choke nozzle 7, expands, passes through the deep-cooler 3 for the compressed gas, being transformed into a gaseous condition in which it is compressed by a compressor 9 and fed into the line leading to the condenser 6.

Title: Improvements in and relating to synchronizing systems for oscillators
IPC: H04N5/12
Filed: 1950-09-12
Abstract: 677,492. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 12, 1950 [Sept. 28, 1949], No. 22427/50. Class 40 (vi). A synchronizing system for an oscillator which has a frequency determining resonant circuit comprises means for deriving from the synchronizing signals and an output voltage from the oscillator a periodic wave which has an energy content which changes in accordance with changes in phase between the synchronizing signals and the voltage derived from the oscillator. The periodic wave is applied to the resonant circuit of the oscillator to maintain the oscillator in synchronism with the synchronizing signals. Fig. 1 shows a television receiver which may be conventional other than the line scanning oscillator unit 9, the saw-tooth output voltage of which is amplified in unit 10 and applied to the line deflecting coils 12. The line oscillator comprises a valve 22 and a tuned circuit 18, 19 which are connected in a Colpitts type circuit so that valve 22 is rendered non- conducting by grid current flow charging capacitor 20 as shown during all but a short period of each oscillatory cycle. Capacitor 29 is charged from the H.T. source 28 via resistor 27 and is discharged through the valve 22 during those short periods in each cycle when the valve is conducting. Thus a sawtooth voltage appears across capacitor 29 and is amplified in unit 10. The resistor 30 has produced across it a negative going pulse waveform which is applied via resistor 33 to the control grid of valve 15 to which negative going line synchronizing signals derived from synchronizing signal separator 8 are also applied. Valve 15 is effectively in shunt with the tuned circuit 18, 19 and is also rendered conducting during the positive going half cycles of the voltage swings across the tuned circuit. During the negative going synchronizing signals valve 15 is cut-off or its conductivity substantially reduced so that energy is effectively added to the tuned circuit at the frequency of the synchronizing signals, the negative pulses applied from resistor 30 are not effective to change the oscillator frequency so that as shown in Fig. 3 it is only during the overlapping portion 42 (shown shaded) of the synchronizing signal 37 and the oscillator output signal 36 that energy is fed'into the circuit 18, 19. Thus the energy fed into the oscillator by the composite pulse 40 is proportional to the phase difference between pulses 36 and 37 so that as this phase difference increases more energy is fed in to bring the oscillator back into synchronism with the synchronizing pulses 37. The control valve 15 may be energized from an additional H.T. supply and capacitively coupled to the tuned circuit 18, 19. Specifications 677,478 and 677,481 are referred to.
