Title: Improvements in coin-freed game apparatus
IPC: G07F17/32
Filed: 1922-07-18
Abstract: 205,566. Jofeh, J. July 18, 1922. Boxing games, mechanical.-A game apparatus, preferably coin-freed, comprises two boxing figures adapted to be oscillated towards each other by two competitors, either of whom, by skilful manipulation of mechanism for directing a blow, can cause his figure to knock his opponent's figure completely over on its pivot. Each boxer 10, 11 is rocked towards the other about its pivot 12 by pressing down the handle 50 to cause the spring-controlled catch 35 to act on the pin 31 on the arm 15, the catch 35 being connected to the handle 50 through the spring-returned slide 57, link 55 and lever 52. The slide 57 is reciprocated in guides 58 on a spring-controlled frame 40 pivoted at 41 to a standard 59 and provided with a catch 61 also engaging with the pin 31, the figures 10, 11 being counter-weighted or spring-controlled to return them to their normal position. The arm 17 of each figure is given an up-and-down motion about its pivot 21 by connecting a pin 22 on the crank arm 23 to a crank arm 28 on a motor-rocked shaft 29. Members 70, each pivoted at 71 to a bracket 72 and connected by a link 76 to the shaft 29 so as to be rocked in unison with the arms 17 of the figures, carry guides 69 in which slide spring-controlled plungers 65 connected by links 66 to the lower end of the lever 52. With this arrangement each competitor endeavours to press his handle 50 so as to cause the arm 17 of his figure to give a blow to his opponent's figure in such a direction that such movement of the handle 50 causes the oscillating plunger 65 to engage in the recessed end of a plunger 64 carried in an arm 63 on the frame 40 of the opposing figure to tilt the frame and release the catches 35, 61 from the pin 31 of the opposing figure so that this figure is knocked over by the blow given by the arm 17. A knocked-over figure is restored to its normal position after a given time from the commencement of the fight by timed motor mechanism, the arm 15 of each figure being connected by a cord 81, Fig. 2, to a link 80 freely mounted on the motor operated shaft 77 on whidh is fixed a disc 78 carrying a crank pin 79, the link 80 lying in the path of the pin 79. To provide a more yieldable figure each arm 15 may be divided intotwo portions 15, 120, the portion 120 being integral with the figure and the portion 15 mounted freely on its pivot 12, a spring 121 connecting the portion 120 with an extension 122 of the portion 15 which has a stop 123 to limit the movement of the portion 120 in one direction.

Title: Improvements in or relating to distortion-correcting circuits
IPC: H03F1/20
Filed: 1954-07-06
Abstract: 754,365. Equalizing networks. WESTERN ELECTRIC CO., Inc. July 6, 1954 [July 9, 1953], No. 19756/54. Class 40 (8). A distention-correcting circuit for correcting imperfections in the loss or delay of a signal transmission system comprises input and output delay lines 6, 7, which may be multisection low-pass wave filters, each terminated by a matching impedance 19, 22, and a series of adjustable transmission paths 26, 27, 38 between corresponding selected points in the lines. Each path may include a thermionic tube 41 or transistor to act as an isolating or amplifying device. In the operation of the circuit shown in Fig. 1, where the paths comprise variable capacitances 35, 36, 37 ganged together, the main part of the signal from the source 13 passes through path 26 substantially without delay and the amplitude and polarity of the signal is adjusted by adjusting the capacitances. A first harmonic " shape " is obtained by the portion of the signal which passes through the next path 27 which signal suffers a phase shift (# 1 +# 2 ). The polarity and amplitude of this signal are similarly adjusted. Similarly the nth harmonic " shape " is derived from the portion of the signal which suffers a phase shift n(# 1 +# 2 ). Thus any desired transmission loss or gain characteristic may be obtained. In a modification, Fig. 2, the loss and delay corrections may be independently corrected. In this circuit, each delay line comprises two halves 50, 50<SP>1</SP> and 60, 60<SP>1</SP>, the ganged capacitances of each corresponding branch being mechanically coupled to the other through either of two linkages 79, 80. When the circuit is used for loss correction the linkage 79 is used, the capacitances in the branches being so adjusted that the amplitude factor in the paths 95, 95<SP>1</SP> are changed by equal amounts in the same direction, and for delay correction the linkage 80 is used, the amplitude factor being changed in opposite directions. A mechanical device is shown in Fig. 5 (not shown), for controlling the choice of linkages 79 or 80 and for adjusting the capacitances. Alternative connecting paths which do not require the use of thermionic tubes are shown in Figs. 3 and 4 (not shown). In a further modification, Fig. 6 (not shown), the connecting paths comprise variable inductors. This circuit may be used to provide simultaneous or independent loss or delay correction depending upon whether the end or the middle inductors are adjusted to take the main signal path. The Specification contains a mathematical explanation of the circuits. U.S.A. Specification 2,348,572 is referred to.

Abstract: 1,006,743. Gas turbine plant; gas turbine combustion chambers; turbines. ESSO RESEARCH & ENGINEERING CO. May 12, 1964 [June 20, 1963], No. 19776/64. Headings F1G, F1L and FIT. To decrease the amount of harmful deposits and corrosion in a gas turbine engine, fuel is burned with not more than 3 % excess air and the resulting combustion products are cooled by recycled turbine exhaust gases, which have themselves been cooled, before being injected into the turbine. In the plant shown, preheated compressed air and fuel in substantially stoichiometric proportions are fed into combustion chamber 37 through conduits 51 and 39 respectively. Cooled turbine exhaust gases pass from conduit 33 through the combustion chamber cooling jacket 35 and conduits 41 and 43 to be mixed with the combustion products from chamber 37, the resultant mixture driving the turbine 3. A portion of the cooled exhaust gases may bypass the cooling jacket 35 via conduit 43. The combustion chamber may communicate with the cooling jacket through holes which facilitate the passage of cooled exhaust gases from the cooling jacket to the combustion chamber along the length of the latter. The turbine 3 drives an air compressor 1, an exhaust gas compressor 7 and drive mechanism 13. The turbine exhaust gases are fed through heat exchanger 47 to preheat the compressed air from compressor 1. A portion of the exhaust gases leaving heat exchanger 47 is exhausted at 57, the remainder being fed through conduit 55 to be cooled in heat exchanger 25, compressed at 7, further cooled in heat exchanger 27 and fed through conduit 33. Heat exchangers 25 and 27 are fed with air from a blower 17 which is driven from the drive mechanism 13. During start-up, i.e. before cooled exhaust gases are available to cool the combustion products from chamber 37, either water or an inert gas may be mixed with the combustion products before the latter reach the turbine 3. Alternatively a valve 60 in conduit 59 may be positioned so that the compressor 7 circulates air rather than cooled exhaust gases during this start-up period.
