Title: Solid electrolyte for a leclanche cell
IPC: H01M6/22
Filed: 1973-07-19
Abstract: 1391044 Solid electrolyte for a Leclanche cell CENTRALNE LABORATORIUM AKUMULATOROW I OGNIW 19 July 1973 [21 July 1972] 34348/73 Heading H1B The solidifying agent of an electrolyte contains an etherified starch which is subsequently remodified by the addition of a reaction product of a saturated alcohol or an organic acid with ethylene oxide. The saturated alcohol may be cetyl alcohol or stearyl alcohol and the organic acid may be palmitic acid or stearin acid. The etherification may be performed by treatment of the starch with epichlorohydrin, propylene dichloride or ethylene oxide. Preferably, the mole ratio of the saturated alcohol or organic acid to the ethylene oxide is 1 : 30 and the reaction product is present in an amount of from 0À2 to 2% by weight of the etherified starch. In one example of electrolyte, the electrolyte additionally contains NH4Cl, ZnCl2, CaCl2, HgCl2, H2O and wheat flour.

Title: Fuel control for gas turbine engine
IPC: F02K3/10
Filed: 1956-11-09
Abstract: 830,007. Gas-turbine jet-propulsion plant. BENDIX AVIATION CORPORATION. Nov. 9, 1956 [Dec. 15, 1955], No. 34358/56. Class 110 (3). [Also in Group XXIX] Control apparatus for gas-turbine engines with afterburner fuel control means 44 comprises a fluid-operated device 109 controlling fuel supply through the control means 44, and two devices controlling fluid supply to the device 109, one 65 being manually actuated and the other 79 being actuated in response to engine speed to permit fluid flow for a range of speeds above a predetermined value. A pump 36 supplies fuel through a main fuel control 34 to the main burners 26 and also up to a piston valve 64 and past a pressure regulator 126 to a cylinder 122 having a leak-off valve 120. A manual throttle lever 54 for the control 34 opens the valve 64 through a cam 56 allowing the pump discharge pressure to pass to a normally closed piston valve 79. On the engine speed reaching a predetermined minimum value set by an adjustment 140, an engine speed sensitive flyweight 112 acts through lever 116 to close the leak-off valve 120 whereby the piston 129 spring connected to the leak-off valve, moves upwards and through its cam 134 closes a leak-off valve 96 whereby the pump discharge pressure builds up beneath a piston 80. As the piston moves up, direct pump pressure is suddenly applied via passage 86 and opens the piston valve 79 to allow pump discharge pressure to pass to the left-hand side of a piston 103 which moves to open the valve 107 allowing fuel to pass through a pump 48 and fuel control 44 to after burners 50. The piston valve 79 is hydraulically locked in its raised position regardless of subsequent engine speed changes. When the lever 54 is moved to allow the valve 65 to close, pump discharge pressure is cut-off at 76 and 86 and spring 82 moves the piston valve 79 downwards to close line 98 and connect both sides of the piston 103 to pump intake pressure via pipe 110 so that spring 105 closes valve 107.

Title: Improvements in or relating to telephone circuits for two-way transmission
IPC: H04B3/20
Filed: 1955-12-09
Abstract: 797,770. Two-way transmission. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 9, 1955 [Dec. 14, 1954], No. 35403/55. Class 40(4). In a two-way arrangement at a radio station, the transmit path 11 is normally conductive and the receive path 16 is blocked, transmission being possible only when no signals are received. A control signal generator 31 blocks suppressor 8 and makes suppressor 19 conductive only in response to speech received in the frequency range 700-900 c/s. A pentode 34 in the generator 31 is tuned to this range by a series resonant circuit 36, 37 in the cathode lead and discriminates against noise. A normally conducting pentode 43 is cut off when pentode 34 responds to an incoming signal and produces a positive control signal. To ensure that speech signals received are not circulated nor transmitted, the bias batteries 44, 45 are chosen so that suppressor 8 is cut off before 19 becomes conductive. Capacitor 41 in the grid circuit of pentode 43 has a charging time of about 1 millisec. and discharges through resistor 40 in about 200 millisec., thereby providing the necessary hang-over between syllables. The minimum signal level required to hold the suppressor 19 conductive no less than that necessary to make it conductive as the resistors 28, 30 are short circuited by rectifier 24, 26. The embodiment shown includes a hybrid 2 and a level control 6. An acceptor circuit 46, 47, tuned to the speech frequencies, guards against circulation of noise of the same frequency during transmission.

A microfilm sound and projection apparatus for instructing students has a pneumatically actuated system which selects a frame from a film strip for projection on to screen 11, and includes a hand-held wand 12 which is pressed against screen 11 at a point chosen by the student to generate an electric signal corresponding to the position of that point. Identical double-row film strips 20, 21 are stored in cells 15, 16 which are movable horizontally and vertically for strip selection by means of a pneumatic binary adder mechanism comprising piston driven adding actuators 25, 26, 27 and positioning actuators 28, 29 each controlled by electrically operated valves. Actuators 35, 36 provide vertical positioning for upper or lower row projection. Each cell contains 64 film strips each having five frames thereon one of which is then selected by means of further binary actuators 40, 41, 42, 43 driving straps 50, 51 to which the selected film strip may be attached by pickers 60, 61 of the kind described in Specification 880, 277. The selected frame on strip 20 is projected on to screen 11 by lamp 80, lenses 81, 82 and mirrors 83, 84, 85, 86, while the identical frame on strip 21 is scanned by a flying light spot provided by rotating mirrors 73 and lamp 70, the transmitted light being sensed by photo-cell 77. A central processing unit is programmed by the output of photo-cell 77 for a chosen frame to respond in a given way to the positional signals due to the students wand 12. These signals are provided when a photo-sensitive element in the wand sense lines of light 100, 101 scanning screen 11 in synchronism with a counter as mirrors 93, 94 rotate in front of lamp 90. The output of the photo-sensitive element gates the instantaneous count of the counter to give rectangular coordinates. An optical pointer for indicating chosen parts of screen 11 consists of lamp and lens 130 and vertical and horizontal positioning means 131, 132. An audio system comprises multi-track magnetisable belt 110, magnetic transducer 113, amplifier 114 and speaker 115. The transducer is positioned at the required track by apparatus 120 described in Specification 819, 790. A modification without the flying spot scanner is used when the central processing unit is selfprogramming. Cells 15, 16 now contain different film strips having separate optical systems which project a different image on to the right and left sides of screen 11 as in Fig.2 (not shown). Pneumatically operated shutters 250-257 shield selected parts of the screen from either projection beam.
