Title: Improvements relating to the manufacture of paper cartridges
IPC: B31C1/00
Filed: 1921-12-24
Abstract: 186,275. LachaussÚe, L. Dec. 24, 1921. Paper pipes and tubes.-Relates to the manufacture of the paper cases of sporting cartridges by winding a paper strip on to a rotary mandrel and consists in providing a cylindrical socket surrounding the mandrel, and means for interrupting the relative rotation between the mandrel and socket when the wound paper makes contact with the inner surface, of the socket. In the form shown in Figs. 1 and 2, the mandrel 3 is rotated, through a friction clutch 4 controlled by a spring 23, by a power shaft 5, so that, with a predetermined friction between the paper and the socket 6, the mandrel ceases to rotate. A shaft 25 carries cams 7, 8, 13, L9, and makes one revolution in a time greater than that required for the winding of a case. After one revolution of the shaft 25 the cam 7 disconnects the coupling 4, the cams 8, 13 operate respectively the cutter 11 to sever the strip, and the ejector 15, and the cam 19 locks the mandrel in position to receive the strip for the next winding. The completed cases are ejected into receptacles 16 in the revolving plate 17. and may then be. subjected to a further compression between two stamps (not shown). Alternative forms are described wherein the socket 6 is rotated when the predetermined frictional force is attained to actuate a positive uncoupling of the mandrel and the shaft 5. In this case the rotation of the socket assists the action of the cutter 11.

Title: Tester for Testing Internal Combustion Engine Ignition Circuits or Components or Parts Thereof
IPC: F02P17/12
Filed: 1967-08-02
Abstract: 1,190,438. Testing ignition circuits. R. G. LEDGER and A. BOOTH. Oct. 7, 1968 [Aug. 2, 1967], No. 35395/67. Heading G1U. A tester for engine ignition circuitry or components or parts thereof incorporates a contact breaker system 9, driven by a motor 7 operating from a relatively low voltage supply e.g. the vehicle battery (which is connected at 1, 2), which enables the primary winding of a transformer 10 to be intermittently energized from the supply to provide a relatively high voltage signal (of the order of 200v) on the transformer secondary. This signal is applied to a continuity testing circuit in which it is rectified at 18 and to which a circuit or component to be tested is connected via a jack plug 21. Continuity is indicated by illumination of the neon 14. The tester has facilities for carrying out tests other than the high voltage continuity test. Low voltage continuity may be tested by connecting a single lead to the jack plug 5. When this lead is connected to an earth in the ignition circuit, lamp 3 brightens, and when it is connected to conductors at the supply voltage, lamp 4 brightens. Ignition coils may be tested by connecting them across a jack plug inserted at 11, with a spark plug connected at 23 via a spark gap 22. When the motor 7 is operated the coil in intermittently energized and a spark should appear across the gap 22. The whole ignition circuit is tested by simply connecting a plug lead to 23, whereon operation of the spark gap shows that it is in order. The tester may be adapted to an alternative input supply by shorting out the resisters 8, 12 using the switch 13.

Title: Improvements relating to fire extinguishing sprinkler systems and alarm devices therefor
IPC: A62C35/64
Filed: 1928-12-03
Abstract: 327,676. Woosnam, A., (Automatic Sprinkler Co. of America). Dec. 3, 1928. Alarms operated by expansion of gases and by flowing liquid in sprinkling systems. - In a sprinkler system, an alarm is given by flowing fluid when the main valve opens, and an alarm is operated at an earlier stage in the occurrence of a fire by the expansion of air in a supplementary piping system. In addition, an alarm is given by the latter means even if the normal supply of pressure fluid has been accidentally cut off. As shown applied to a wet-pipe system, when the main valve 5 opens owing to the fusing of a head 9, water flows by pipes 7, 18, and 45 to operate the fluid motor 46 of a gong 50. and a diaphragm 39 which acts to close a switch 40 in the circuit of an electric bell 44. The flow is controlled by a retarding device 10 in which a drip pipe 17 is controlled by a valve 13 and a diaphragm 11 which is not responsive to momentary surges at the valve 5. The water motor 46 and diaphragm 39 can also be operated by water from the distributing pipe 8 passing through a pipe 25, which is normally closed by a valve 27. The pipe 25 can also be supplied with water from an additional piping 22, for example the piping of a domestic supply, check valves 21, 24 being provided in the connecting pipe 23. The valve 27 is opened by a weight 31 controlled by a diaphragm 34 which is acted upon by air expansion in a supplementary piping 60 and air bulbs 36. By this means, heating of a bulb 36 by an incipient fire may open the valve 27 and permit the alarms 50, 44 to operate before the main valve 5 has opened. The lever carrying the weight 31 has a tail 51 adapted to close a switch 52, 53 in the circuit of the bell 44. By this means, an alarm is given even if, for any reason, the water supply from both pipes 1 and 22 should be cut off. As applied to a dry-pipe system, the retarding device 10 is omitted from the pipe 7, which in this case leads from the neutral chamber of the dry-pipe valve. The pipe supplying the valve 27 is carried from the water main below the drypipe valve. Specifications 326,140 and 330,254 are referred to.

Title: Apparatus for preventing self-excitation of capacitively loaded synchronous machines
IPC: H02K19/36
Filed: 1957-11-20
Abstract: 828,117. Protective arrangements for capacitively loaded synchronous machines; alternators. MASCHINENFABRIK OERLIKON. Nov. 20, 1957 [Dec. 12, 1956], No. 36215/57. Classes 35 and 38 (4). Apparatus for preventing the self-excitation of capacitively loaded synchronous machines and thereby prevent the occurrence of excessive voltages comprises current and voltage transformer arranged to excite a relay in such a manner that the relay only operates to prevent self-excitation of the machines when the value of the ratio between the capacitive reactance of the load and the inductive reactance of the machines falls below a predetermined value. A synchronous machine 5 is connected to the three phase lines R, S, T of a polyphase system over a switch 20, the operating coil 19 of which is energized when a relay 9 of the wattmetric type operates to close its contact 18. The relay 9 has two operating coils, one a voltage coil 8 fed from the series connected secondary windings of two voltage transformers 6, 6<SP>1</SP>, the primary windings of which are connected to the phase lines R, S, T. The other operating coil of the relay 9 is a current coil 16 and this coil is fed from the secondary winding 15 of a current transformer 12. This current transformer 12 has two primary windings 13, 11, the winding 13 being fed from a current transformer 14 placed in one of the phase lines S so that the primary winding 13 is responsive to the capacitive load current I c  whilst the other primary winding 11 is fed from the secondary winding of the voltage transformer 6 over a reactor 10, the reactance of which is chosen to simulate the inductive reactance of the machine 5. Thus the primary winding 11 is responsive to a current I L  which is a measure of the inductive reactance of the machine 5. When the ratio of the currents I C , I L  falls below a predetermined value the output of the secondary winding 15 is such as to cause the relay 9 to operate to trip the switch 20 so to disconnect the capacitive load from the machine 5. As an alternative to disconnection the switch 20 may be arranged to switch in compensating reactors. In a further embodiment each reactor 10 may be divided into two coils, one with and one without a saturation characteristic. When more than one machine is used, they are connected in parallel and in this case each machine has a corresponding reactor 10 also connected in parallel, means being provided to disconnect the corresponding reactor.
