Abstract: 724,981. Reciprocating electric motors. GLAS-COL APPARATUS CO., Inc. March 26, 1953, No. 8453/53. Class 35. [Also in Group XI] A reciprocating electric motor comprises a magnetic plunger 52 on the base of an electrically heated container 24 for a milk bottle (see Group XI), said plunger being moved in one direction by a solenoid 54 and in the opposite direction by a helical spring 56. A pin 64 on the plunger engages a pivoted arm 62 actuating a switch 60 intermittently energizing the solenoid and thereby agitating the bottle. In Fig. 8 the magnetic plunger 102 is horizontal and has pins 104 engaged by a forked extension 108 on the container. The plunger is attracted by a solenoid 112 and is returned by springs 110, the end of the plunger moving a pivoted arm 116 of a switch 114 for the solenoid. The return motion of the plunger may be slowed by a dashpot arrangement with an air leak.

Title: Improvements in or relating to smoke detector circuits

Abstract: 1,009,271. Semi-conductor circuit. ASSOCIATED FIRE ALARMS Ltd., and B.J.L. WHITE. March 2, 1964 [March 4, 1963], No. 8549/63, Heading H3T. [Also in Division G1] The voltage at a point 17 between an ionization gauge 10 responsive to the amount of smoke in the atmosphere, and a resistor 11, which may be a second ionization chamber closed to the atmosphere, is applied to the modulator of a field effect transistor 14 fed from an LT source 16, and when as a result of smoke the voltage drops below that at point 18 current through transistor 14 ceases and point 20 which is set to become positive with respect to point 19 eventually renders transistors TR1 and TR2 conductive, diode D3 making the arrangement bi-stable. The larger current drawn from the source by the transistors actuates a relay in the supply lead. Capacitor C ensures that transistor TR1 does not conduct immediately on reset. A number of such circuits may be connected to a single LT power source, and the relay may be responsive to the total current drawn. Transistor 14 may be coupled to point 17 by a capacitor to make the circuit responsive only to rapid changes. Component values are exemplified.

Title: Improvements in or relating to machines organised for applying pressure to shoe bottom parts
IPC: A43D95/02
Filed: 1951-04-13
Abstract: 702,282. Boots &c. BRITISH UNITED SHOE MACHINERY CO., Ltd., and KESTELL, T. A. April 15, 1952 [April 13, 1951], No: 8591/51. Class 17(1) In machines in which pressure is applied to shoe bottoms such as in sole moulding, sole laying and levelling and lasted bottom ironing, and where the power means act through mechanical connections a yieldable hydraulic device is provided which causes the pressure to be applied first at a low value and then at a predetermined higher value at which the device yields. As applied to the shoe bottom press described in Specification 216,937, [Class 17(i)], the device replaces the heavy spring power transmission unit and is arranged to prevent full load falling on the operating toggles until the levers are 20 degrees from the straight. The device comprises a cylinder 101 which slides over a piston 111 having a valve unit 113 in its end. The valve has a ball 129 held seated on a shoulder 127 against a spring 143 by a rod 163 loaded by a spring 161 and arranged to be lifted by a lever 171 actuated by a rod 177 controlled by a cam on the main driving shaft. A spring 109 tends to keep the device extended. The device is pivotally connected to the machine frame by the engagement of screws in holes in projecting bosses 153 of the piston 111. In operation, the power transmitting toggles of the prior machine engage an abutment 103 with the valve 113 open so that the cylinder 101 moves up the piston 111 withlittle resistance so that the shoe is engaged by a low pressure until the toggle links are within 20 degrees of straight at which point the lifting lever 171 is actuated to allow the spring 161 to close the valve 113 thus locking the piston and cylinder together until the pressure is sufficient to blow the valve 113 against the spring 161. The arrangement is such that the device operates for both pads of the prior machine and the rapid return of the cylinder 101 is facilitated by ports 117 in the upper part of the piston which allows the fluid to enter the part of the cylinder and to return through passages in a sleeve 185 as the device again extends. The pressure at which the valve 113 blows determines the pressure applied to the work and is set by tensioning the spring 161 through a handwheel 159 the setting being indicated by a pointer 221 moving over a plate 223.

Abstract: 1,260,792. Regulating reactor cooling system. SIEMENS A.G. 23 Feb., 1970 [1 March, 1969], No. 8656/70. Heading B1X. [Also in Divisions G4, G6 and H1] A system for indicating when a liquid is boiling, and possibly supplying a control signal for a heater, comprises an inverted funnel 2 inserted in the liquid. As boiling commences bubbles are entrained causing an upward flow in the liquid, the funnel magnifies the flow velocities and causes fluid to gush out of the top of the funnel. The presence of the liquid is detected by the liquid (which may be molten metal), shorting out contacts 3 and energising a relay 32. In alternative embodiments the liquid sensor may comprise:- (1) A resistance thermometer which unbalances a bridge on being cooled by the liquid; (2) An orifice out of which gas flows and which is blocked by the liquid to produce a pressure change; (3) A pair of resistance wires arranged as the arms of a bridge, the wires detecting the level of the liquid by the amount of resistance not shorted out in the arms. In the pressure vessel 8 of a nuclear reactor (Fig. 5), detectors 7 are mounted above funnels 2 which dip into the coolant flowing around fuel channels 11. The detectors are connected to indicating device 73 which forms part of the regulating system for the reactor.
