Title: Device for measuring the doubling time of a quantity which has a substantially exponential variation
Inventor: LACOUR JACQUES
IPC: G21C17/14
Filed: 1964-03-23
Abstract: 1,020,349. Selective signalling systems. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 23, 1964 [April 2, 1963], No. 12213/64. Headings G4H and G6C. [Also in Divisions G1 and H3] In a system for measuring the doubling or halving time of a variable, e.g. the output current of an ionization chamber 1 measuring the power of a nuclear reactor, an amplifier 4 is associated with a plurality of binary-weighted resistors R 1 -R 5 , the connections of which may be altered by a switching unit 13. At any time the conductance between contacts 6, 10 is equal to that between contacts 6, 11, R 0  being equal to R 1 . As the input rises to double its value, the output of amplifier 4 rises until it reaches the same potential as contact 11, at which point a threshold device 32a, Fig. 6, allows a pulse from a clock source 36 to reach counter 33, the stepping of the counter in the forward direction being controlled by line C. A decoding matrix 37 energizes the next one of relays 38 to change the connections so that the resistor which was across contacts 6, 10 is connected between contacts 6, 11 in parallel with all the preceding resistors, and the following resistor is connected across contacts 6, 10. The process repeats when the input has again doubled. If the input is falling, threshold device 32b steps counter 33 in the reverse direction each time the output of amplifier 4 reaches zero. The time interval between successive switching operations is measured by the circuit shown in Fig. 7. When either of threshold devices 32a, 32b produces an output, the contents of counter 41, which is continuously supplied by clock source 42, are transferred to a register 43 and the counter is reset. Register 43 may be connected to a printer to record the successive doubling or halving periods.

Title: An Improved Relay for Electric Circuits.
Inventor: CHRISTIAN DAVID ADAM
IPC: H01H47/14
Filed: 1918-07-26
Abstract: 131,413. Christian, D. A. July 26, 1918. Automatic exchange systems.- A relav for testing if a line of a telephone system is engaged has two equal opposing windings 1, 2; the winding 2 is connected to an armature contact 4 normally closed and operated prior to the other contact or contacts 14, 15, the common junction 3 of the windings being connected to the controlling circuit. In the arrangement shown in Fig. 3, the test lead 11 of the outgoing line is connected to battery 12 through a resistance 13 which is equal to the resistance of the winding 2 of relay A<1>. When the circuit of the test lead is closed, if the line 11 is free the current through the winding 1 will be strengthened and that through winding 2 weakened so that the armature 14, 15 will be attracted to connect the speaking leads through to the leads 16, 17 of the outgoing line. If connexion is now made between a point 18 on the engaged multiple of the outgoing line 11 and a point 3 of relay A<2> no change will occur in the relay as these points are now points of equipotential, and consequently relay A<2> will not operate to connect its speaking leads through the leads 16, 17. The relay may also be used in the private branch exchange systems described in Specification 131,487, in which a number of lines extend from the connector bank contacts to a subscriber's station, the wipers of the connector rotating automatically to find an idle one of such lines. As used in this system, the test relay has three windings, two of which are differentially wound as described above and the third, which is of lower resistance than the other two, is shortcircuited until the relay is fully operated.

Title: Improvements in or relating to processes for the bronzing of copper and copper alloys
IPC: F16K31/46
Filed: 1935-04-24
Abstract: Copper and copper alloys, especially brass, are bronzed by first rubbing the polished surface, freed from grease if necessary, with a swab which has been moistened with a solution of water, hydrochloric acid and copper sulphate, then removing any residues adhering to the slightly corroded surface and then treating with a stream of gas containing ammonium sulphide so that the gas sweeps over the metal surface.  The acid solution is made up of 1000 c.c. of water, and 20 c.c. of concentrated hydrochloric acid in which is dissolved 20 grams of crystallized copper sulphate.  To produce the stream of gas, air or other gas which does not decompose ammonium sulphide is led from a compressed air &c. container or a hand-blower through a 10-20 per cent solution of ammonium sulphide.  To eliminate any cloud or spot formation in the bronzed surface, the latter is rubbed down lightly with a polishing powder or again treated with the acid solution.

Abstract: 706,856. Lathe details. WALDRICH, 0. May 28, 1951 [May 26, 1950], No. 12469/51. Class 83 (3) A lathe according to the parent Specification with a cylindrical bed extending about the spindle axis is modified by the provision of carriage guideways inclined downwardly towards the rear of the machine, tailstock being supported on the front and back of the cylindrical part of the bed. The bed 5, Fig. 1, extends approximately for 120 degrees around the spindle axis and the tailstock 10 is supported on guide surfaces at the base and rear including T-slots 13, 14. Clamping is effected in these slots by strips such as 44, Fig. 2, tightened by bolts 43 and spring discs 46. The spring pressure is released during adjustment by operating a handwheel 15 which moves a piston 40 and transmits pressure through a ,plastic semi-fluid synthetic medium to pistons 47 pressing on the .clamping bolts 43. Similar clamping and hydraulic releasing means are stated to be applicable to the carriage, crossslide and tool clamping means. The carriage 20, Fig. 1, is inclined downwardly towards the rear and carries a tool 22. Tailstocks.-The tailstock 10 is roughly adjusted by a motor 51, Fig. 1, driving, through worm gearing 50, Fig. 2, a screwed bush 29. The rough adjustment may be automatically halted when the centre 39 touches the work and fine adjustment effected through the handwheel 16. The latter comprises a piston operated by a screw 31 which transmits pressure to a larger piston 34 acting through spring discs on an end pad 36 of a bearing assembly carrying a " live " centre 39. In an alternative arrangement with an entirely hand drive a ratchet may be incorporated by which the rough adjustment becomes inoperative when the centre engages the work and further movement of the handwheel operates the hydraulic clamping arrangement similar to the above.

Abstract: 797,775. Latches. PARKES & SONS. Ltd., J., and BUTTER, F. J. Oct. 1, 1956 [April 25, 1956], No. 12615/56. Class 44 Relates to tubular mortice latches operable by a spring-loaded retractor which can be actuated by either of two roll backs associated with knobs on opposite sides of a door and in which, when a push button on the inside knob is operated, prevents the outside knob from being turned, the outside knob being releasable by turning the inside knob or by pushing on the latch bolt. According to the invention, in such a latch in which normal operation of the retractor by either knob-actuated roll back directly. withdraws the bolt against the combined load of bolt and retractor springs, but direct forcing in of the bolt as by riding over the usual striking plate when slamming the door, does not impose the spring loading of the retractor upon the bolt, such permitted inward movement of the latch bolt independently of the retractor, is utilized in the event of the outside knob being locked against turning by pressing the button in the inside knob, to operate a spring-loaded catch so as to release the outside knob for turning, the catch being carried by the retractor whereby the knob-locking mechanism may also be released by turning the inside knob and thereby operating the retractor to retract the latch bolt. As shown, a spring-loaded retractor 10, which is actuatable by either of two roll backs 11, 12 associated with outside and inside knobs 13 and 14 respectively, is formed with claws 20 which engage a bolt tail 21 of a forwardly spring-loaded latch bolt. A push-button 23 in the knob 14 is fixed to one end of a slidable spindle 24, the other end of which carries a non- circular block 25 engaged in a non-circular hole in a fixed stop plate 26.
