Title: Improvements in microwave oscillators employing lasers
Inventor: DUNSMUIR ROBERT
IPC: H01S5/32
Filed: 1963-04-11
Abstract: 1,077,026. Lasers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 3, 1964 [April 11, 1963], No. 14615/63. Heading H1C. The components of radiation of different wavelengths emitted from a semi-conductor laser are caused to beat together to generate a microwave radiation of beat frequency which modulates the current flowing through the laser to inject a microwave radiation into a microwave resonator associated with the laser. As shown in Fig. 1 a gallium arsenide/phosphide PN junction laser is connected between the inner conductor 3 and outer conductor 2 of coaxial type microwave resonator 1 and has one edge D of the PN junction coated with a non- reflecting layer so that radiation emitted from the junction may pass through a hole in the resonator, lens 6 and be reflected back by plane mirror 7. The components of the stimulated radiation beat together to produce a microwave radiation of frequency corresponding to the separation of the components and this microwave radiation modulates the current from battery 3<SP>1</SP> flowing through the diode 5. The resulting microwave radiation is injected into the resonator 1 where it is extracted by loop 4. In the arrangement of Fig. 2 (not shown) the inner conductor (11) is hollow and the optical system is located within the hollow conductor. The PN junction extends parallel with the axis of the resonator. A waveguide type of resonator may be used instead of the coaxial type and the laser may be used without the optical components.

Patent GB-686583-A (GB)
Title: Improvements in or relating to quantized signal transmission systems
IPC: H04B14/06
Filed: 1951-06-26
Abstract: 686,583. Pulse code modulation systems. WESTERN ELECTRIC CO., Inc. June 26, 1951 [June 29, 1950], No. 15122/51. Class 40 (v). In a communication system in which the signals are sampled and variably quantized, the size of the quantum, or difference in level between successive quantized samples, is made relatively small for signals of slowly varying amplitude and relatively large for signals of rapidly varying amplitude. The embodiment described comprises a system in which the changes of level of successive quantized signals are transmitted rather than the levels themselves. The difference 14 between the input signal 11 and the reconstituted signal 13, derived from the output of the integrator 23, is produced in the subtractor circuit 12 and fed to a level control circuit 16. The output 17 therefrom is sampled and quantized in circuit 18 producing a signal 19 which operates coder 25 feeding coded signals to the transmission path 27. The output of quantizer 18 is also passed through a second level control circuit 21 producing an effect on the quantized signal which is the inverse of that of the first control circuit 16, so that the output 22 is a quantized replica of the signal 14. Signal 22 is applied to the integrator 23 which provides a decoded version 13 of the original signal 11, for application to the subtractor 12. Signal 22 also provides a control voltage for circuits 16 and 21 after a delay in circuit 24 of one sampling period. This causes the gain of circuit 16 to depend, at any sampling instant, on the amplitude of the preceding restored sample which produces the desired quantum level control. The receiver, at the other end of transmission path 27, comprises a decoder 28 followed by level control circuit 31, controlled through delay circuit 32, and integrator 34 which correspond to the circuits 21, 24, 23, respectively, at the transmitter. Typical related waveforms of signals 11, 13, 14, 17, 19 and 22 are given, Fig. 2 (not shown) Amplifiers, with controlled feed-back paths, for use as level control circuits 16, 21, 31, are described, Figs. 3, 4 (not shown). Specification 652,212 and U.S.A. Specification 2,605,361 are referred to.

Abstract: 199,392. Ingersoll-Rand Co., (Assignees of Haight, H. V.). June 19, 1922, [Convention date]. Percussive drills.- In a machine for opening out the holes in drill-shanks and other hollow articles, having a fluid actuated double-ended hammer piston, the hammer is adapted to drive in or retract the punch according as it strikes one or the other of a pair of anvil blocks in one of which the punch is mounted. The hammer J is mounted in a cylinder B to either end of which fluid may be admitted by an oscillating or other type of valve O. The anvil block R carrying the punch Z is allowed a limited outward movement in the cylinder after which it engages a crosshead S rigidly connected by bolts W to a rear crosshead U in which a second anvil block T is mounted. The work Y is held manually or clamped and rests in a guide X<1> which is pivoted in the crosshead S and operates the fluid pressure control valve j. After delivery of the driving blow, the work and attached punch are drawn forward to bring the rear anvil block T within range of the hammer which is then actuated to withdraw the punch by depressing the guide X<1>. The valve j may be actuated by a treadle in which case the guide X<1> is rigidly secured to the crosshead S. The apparatus may be independently mounted or may form part of a drill-sharpener &c.

Title: Improved bottle washing machine
IPC: B08B9/44
Filed: 1925-06-12
Abstract: 246,020. Marks, E. C. R., (Aktieselskabet Althuon & Nielsen). June 12, 1925. Bottles, washing.-A combined bottle washing and rinsing machine is provided with an endless conveyer 6 having rows of bottle-holding cups 5 which are adapted to pass through cleaning liquid in a container 1. The conveyer is intermittently driven by a single set of chain wheels 4 and is guided by a rail 8. The cups 5 are filled with bottles from a tray 5 during the times when the conveyer is stationary. The bottles after insertion are moved upwardly and become subjected to hot liquid from jets 10. Preferably the bottles pass several times through the cleaning liquid at the bottom of the container. Subsequently they pass out of the container through an opening normally closed by a hinged flap 14 and fall into pivoted cups 16 which are afterwards moved into a position in alignment with a row of cups 11 in a rinsing wheel disposed in the rinsing device 2. Each cup 16 comprises a cylinder with a longitudinal slit 17 and is adapted to co-operate with a pivoted bottom 18 having a corresponding slit. The bottles are pushed into the cups 11 by knife-shaped levers 20 which pass through the slits. The return movement of the bottoms 18 lags behind that of the cups 16 to permit pieces of broken bottles, if any, to fall out of the cups. The bottles carried round by the rinsing wheel are rinsed with clean water and eventually fall into a pivotally-mounted receiver 26 which is moved to deliver the bottles on to a tray 27. Three cam discs on a common shaft 31, acting in conjunction with links and levers, provide the means for opening the flap 14, for moving the cups 16, bottoms 18 and feed levers 20, and for actuating the receiver 26.

Title: Improvements in or relating to a process for producing pure carbides of the metals tungsten, chromium and molybdenum
IPC: C01B31/30
Filed: 1955-05-27
Abstract: Tungsten chromium or molybdenum carbide substantially free from uncombined carbon, is produced by heating of the metal or decomposable compound of the metal in a mixture of a hydrocarbon and hydrogen, sufficient hydrogen being present to prevent decomposition of the hydrocarbons and deposition of carbon.  The maximum ratio of hydrocarbon to hydrogen permissible is calculated by assuming that in the case of hydrocarbons other than methane, decomposition and recombination to form methane takes place and by ignoring the additional hydrogen required for such conversion.  The maximum percentage of methane permissible at 800 DEG C. is ca. 8 per cent. Carbides specified are W2C, WC, Cr3C2 and Mo2C.  The carbides are reckoned to be pure if the analysis shows less than 0.05 per cent. carbon. Elements other than carbon may be present.  Metal compounds which may be used as WO3, MoO3, Cr2O3; H2WO4, H2MO4, H2CrO4; Am2WO4, Am2 CrO4, Am2MO4. Hydrocarbons specified are methane, ethane, propene, propane, butenes, butanes, heptanes and benzene. Hydrocarbons which are gaseous at room temperature are preferred. The temperature preferably exceeds 950 DEG C.  The product is preferably rapidly cooled.  Alternatively the percentage of hydrocarbon in the gaseous mixture may be increased as the temperature is lowered.
