Title: Improvements in or relating to coin-freed table shooting apparatus
IPC: G07F17/38
Filed: 1946-08-07
Abstract: 625,437. Targets. GEISER, W. Aug. 7, 1946, No. 23441. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 8, 1947]. [Class 20(i)] [Also in Group XVIII] In a coin-freed miniature shooting range, the target is carried by an electrically-driven trolley running on rails extending the length of the range so that the trolley can be brought up to the firing point for the target to be inspected. The trolley is normally located at the firing point and a coin is inserted into it to release its driving mechanism for a predetermined number of runs to and from the far end of the range. The trolley shown is driven by a reversible motor w controlled by forward and reverse switches i l and a main switch e. Initially, with the trolley at the firing point, all three switches are open. An inserted coin passes down a chute a and pushes aside a detent b to release a spring-actuated arm d which thereupon closes the main switch e. A pivoted finger lever g is then depressed which closes the switch i so that the trolley runs down the range to the far end where the finger lever g is knocked back by a ramp h to break the motor circuit and stop the trolley. The target backing k is pivoted at m and connected to the reverse drive switch l so that, when the target is hit, switch l closes and the trolley returns to the firing point where it is stopped by a ramp o which engages an extension n of the target backing k to restore it and open switch l. After inspecting the target the trolley is returned for the next shot by again pressing the finger lever g when the cycle is repeated. Each time the lever g is actuated it turns a nine-tooth ratchet wheel p clockwise by one tooth and, on the third actuation i.e. after two shots have been fired, one of three pins u on a disc fast with the ratchet wheel restores the arm d and one of three teeth q on the disc opens. the switch e. A further coin must then be inserted to operate the apparatus. The number of shots allowed for each coin can be altered by changing the ratchet wheel p and its disc. A lamp f illuminates the target whilst the main switch e is closed. If the bullet fails to rock the target the switch l can be closed to return the trolley by pulling a hand lever r which is connected by a cable s with a pivoted arm t adapted to engage over the target extension n when the trolley is at the far end of the range.

Title: Improvements in and connected with selfacting alarm and signal systems in fire sprinkler installations
IPC: A62C35/60
Filed: 1922-08-31
Abstract: 207,610. Murray, N. L. Aug. 31, 1922. Fire-alarm systems and apparatus.- In self acting sprinkler fire-extinguishing systems means are provided for transmitting an alarm signal when a fire occurs or when the system is deranged. A pipe 5 leads to a sprinkler and when this is in action a valve 7 opens and allows water to flow through a pipe 8 and drive a Pelton wheel 9 which operates a gong 10. Connected to the pipe 8 is a tube 12, Fig. 2,. which is annularly arranged in a casing 11, Fig. 1, and acts as a Bourdongauge tube. It is connected by adjustable members 18, 19 to a finger 17 so that on a variation of pressure occurring in the tube 12 the finger 17 moves to alow a fan 16 of a clockwork motor to rotate. This motor drives a wheel 13 having wipers which engage a projection on a bar 19a pivoted at 18a, and so cause it to break an electric circuit through a blocks 25. The wheel 13 may be loosely mounted on its shaft and driven by a pin 21 which allows rotational play; a spring 22 also connects the wheal 13 to its shaft and is arranged to take some torque when the wheel begins to revolve to prevent a wiper remaining in engagement when the motor stops. Another pressure tube may be connected by a tube 23, Fig. 1, to a point below the valve 7, and a waste pipe 24 ensures that if the main cock 6 is turned off, reduction of pressure in the pipe 23 will also cause the apparatus to send an alarm.

Patent GB-240164-A (GB)
Abstract: 240,164. Aktieselskapet Krystal. Sept. 17, 1924, [Convention date]. Crystallizing. - Coarsely granular crystalline material is obtained by circulating a saturated solution containing suspended crystals in a closed circuit through means for supersaturating the solution either by cooling or by heating and evaporation, means for removing superfluous small crystals either by separating them or by adding an unsaturated solution and means for separating large crystals. As shown in Fig. 2, the saturated solution containing suspended crystals is circulated by a propeller b through a heater o and a channel p in which evaporation takes place. Part of the liquid containing small crystals is withdrawn from an enlargement r through a settling chamber t by a pump s which returns the liquid through a pipe u. Large crystals fall through an opening g up which a current oi liquid withdrawn from the enlargement r by a pump v is passed to prevent the falling of the small crystals. Large crystals are removed by a conveyer k. Fresh solution is introduced into the circuit through an inlet n<1>. If the solution does not form a sufficient number of new small crystals, these are introduced through an inlet n<2>. Instead of separating small crystals by settling in the chamber t, a filter or centrifugal separator may be used or unsaturated solution may be introduced. In a modification, the heater o and evaporating chamber p are replaced bv a cooler, and solution containing small crystals is withdrawn through a funnel placed in the centre of the channel below the propeller b, and is passed into a settling-chamber, the liquid from which rises through the outlet g for the large crystals. Specifications 132,787 and 171,370 are referred to.

Abstract: 488,517. Current meters. SIEMENS &. HALSKE AKT.-GES. Sept. 3, 1937, No. 24136. Convention date, Nov. 23, 1938. [Class 37] [Also in Group XL] In a device for the audible detection and of unmodulated high-frequency currents, a low frequency audible detector 6 and a measuring instrument 5 are connected through a rectifier 4 across the secondary windings 3 of a transformer 2 which is excited by the high-frequency currents through the primary windings 1 and by an audio-frequency current through the second primary windings 10. the arrangement being such that the limiting value of the rectifier is exceeded, causing the detector 6 to respond, only when high-frequency currents are being received. The limiting value of the rectifier may be increased by applying a direct potential. If the apparent impedance of the second primary winding is equal to the resistance of the low frequency source, the response of the detector 6 will be independent of the magnitude of the highfrequency current, but if it is smaller than this resistance the response varies with the magnitude.
