Title: Improvements in or relating to the production of cuprous chloride
IPC: C01G3/05
Filed: 1933-09-19
Abstract: An aqueous solution of cuprous chloride is prepared by reduction of a cupric chloride solution with copper or a copper alloy, at at least 80 DEG  C., in the presence of sufficient alkali metal chloride to retain the cuprous chloride in solution, and in the absence of ammonium salts.  Chlorine may be passed into a solution containing dissolved copper, e.g. cupric or cuprous chloride or cupric sulphate, and say sodium chloride, in the presence of metallic copper and preferably at 80 DEG  C. or above. The flow of chlorine is then stopped and the solution allowed to stand until the cupric chloride is reduced.  Alternatively the alkali metal chloride and copper are added to a previously prepared cupric chloride solution.  The solution may be neutral or acidified, and oxygen is preferably excluded during the reduction. The copper salt concentration may be as low as 1 per cent initially while that of alkali chloride is preferably at least 10 e.g. 15--30 per cent.  Solid cuprous chloride may be recovered p  from the solutions for example by dilution with water. Specification 4626/88 and 13336/93, [both in Class 1], are referred to.  The Specification as open to inspection under Sect. 91 includes the use of lower temperatures, e.g. 25 DEG  C., for carrying out the reaction.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1284517 Transistor pulse circuits INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [30 April 1970] 26434/71 Heading H3T [Also in Division G1] Pulse shapes.-A pulse train from the breaker contacts 10 (Fig. 3) of an I.C. engine is fed through a unit 24, comprising a filter 100 (Fig. 5) and a multivibrator having a normally blocked transistor 95 which is opened by each input pulse to produce a negative output pulse 105 on line 92. The output pulse duration is determined by the time taken for capacitor 104 to charge to a potential which opens transistor 108 and blocks transistor 95, and is made to coincide with the input pulse duration. Delay circuits.-A potential on line 96 (Fig. 5) controls the extension of each pulse 60 fed to a monostable multivibrator comprising transistors 41, 45. The input potential charges capacitor 31. Each pulse 60 blocks diode 34, opens transistor 41 and blocks transistor 45, to start the output pulse 61. Capacitor 31 discharges through transistor 50 at a rate determined by manually adjustable bias potential applied on line 26. When the capacitor potential applied is sufficiently low, diode 144 conducts and opens transistor 45 to end the output pulse 61. The leading edge of pulse 61 on lead 68 (Fig. 4) opens transistor 71 to produce a negative pulse at 84 which is blocked by diode 75. The trailing edge blocks transistor 71 to produce a positive pulse which is amplified at 78, 80 to form output pulse 62.

Abstract: 793,360. Valves. MULLER, J. Sept. 13, 1954 [May 19, 1954], No. 26447/54. Class 135. An automatic regulator for regulating the pressure of a fluid for a given flow in a duct connecting a source of fluid pressure to a consuming apparatus, comprises a duct 1 which includes in series a first venturi passage 2 co-operating with a valve regulating member 3 connected by a linkage 22, 20, 19 to a hermeticallysealed bellows 12 and a second venturi passage 4, 5 co-operating with a valve regulating member 6 connected by a linkage 45, 43, 42, 40, 39 to a hermetically sealed bellows 32. The bellows 12, 32 are subjected externally to the pressures in chambers 7, 8 downstream of the valve members 3, 6, respectively and loaded by springs 14, 34. The pressure in the chamber 7 and the position of the valve member 3 are determined by an adjustable screw-threaded spindle 16 whilst the pressure in the chamber 8 and the position of the valve member 6 are similarly determined by a screw-threaded spindle 36. The spindle 16 also through a linkage 24, 25, 26, 28 adjusts the venturi flow passage 4 to give a flow rate corresponding to the position of the valve member 3. Pressure in the chamber 8 is transmitted through a line 53 to act on a spring- loaded diaphragm 55 which acts as a damper to absorb hammer effects, a scale 58 giving an indication of this pressure. A lever 40 besides being part of the linkage 45 ... 39 coacts with a switch 52 and with a spring-loaded button 50 to open a normally closed valve 49 so that in the event of a sudden increase in pressure in the chamber an electric motor driving the supply source is stopped and the valve member 3 closed.

Title: Improvements in or relating to time alarm mechanisms
IPC: G04B25/04
Filed: 1936-09-29
Abstract: 483,378. Alarm mechanism. MAW, T. F., and AGAR, M. F. Sept. 29, 1936, No. 26457. [Class 139] A silent alarm mechanism intended to be worn on the person comprises an indicator element which, when released, presses upon the wearer. In the application shown, the alarm mechanism is embodied in a wrist watch, the indicator being a metal loop 12 pivoted on pins 13, 14 and pressed, when released, against the wrist of the wearer by a coil spring 15. The alarm mechanism is situated between the dial 18 and the front movement plate 19. The alarm setting dial 20 is substantially coplanar with the dial 18, is rigid with a ratchet wheel 21, and is frictionally mounted on the hour hand arbor so as to be driven thereby but adjustable relatively to the hour hand for alarm setting. This setting is achieved by repeatedly depressing a plunger 32 which causes a pawl 30 to rotate the ratchet tooth by tooth anticlockwise until the time mark at which the alarm is desired, is beneath the hour hand. The dial 20 and hour hand then rotate together until the hour marks on dial 20 register with the hour marks on the dial 18, and at the moment of registration the alarm is released by the following means. A cam 34 associated with the dial 20 has a point 35 for actuating a member 49, 48 which is controlled by a spring 50 and lugs 51, 52 coacting with lug 53 and shoulder 54 on a bridge 151 fixed to the front plate 19. A notch 47 in member 48, 49 actuates an arm 37 rigid with an arbor 38 which also carries an arm 36 normally latching a lug 41 on the alarm indicator 12. As the dials 20 and 18 become registered with one another at the alarm time, point 35 rocks member 48, 49 counterclockwise, stretching spring 50. Lug 51 comes behind shoulder 54 and lug 52 is raised free of lug 53. At the exact moment of registration, point 35 wipes past point 49 and spring 50 causes lug 51 to move free of shoulder 54, after which the spring moves part 48 slidably upwards along bridge 151 so that notch 47 rocks parts 37, 38, 36 whereby the latter releases lug 41 on indicator 12 and the latter is pressed by its spring 15 against the wearer's wrist. To reset the mechanism, indicator 12 is raised against spring 15 so that a piece 46 on it restores arm 36 and therefore parts 37, 47, 48, to latched position. The lug 41<1> and piece 46 are on a plate 42. which is slidably mounted on indicator 12 by pin and slot 44, 45 so that by sliding this plate 42 downwards, the lug 41 is locked in a recess 43 and the indicator can not be released. In a modification, Figs. 8 and 9 (not shown), the ratchet wheel 21 is subtantially larger than the alarm setting dial 20 and the indicator 12 is of horse-shoe shape across which is fixed a plate for contact with the wrist. The indicator may be formed as a false back for the watch movement. Reference has been directed by the Comptroller to British Specifications 16418 /92, and 218,200, [both in Class 139], and U.S.A.

Abstract: 777,589. Internal shoe-drum brakes. HUNTON, A. W. Oct. 26, 1955 [Sept. 14, 1954], No. 26636/54. Class 103 (1). In an adjusting and locking device for an internal shoe-drum brake, a screw 9 having a conical head 8 adapted for wedge action on members 4 pivoted at 3 to the brake shoes 2, engages in an internally screw-threaded sleeve 10 secured to the brake back plate 1 adjacent to the pivoted ends of the brake shoes 2, whereby rotation of the screw results in movement on the shoes relatively to the brake drum it being possible if desired to lock the shoes in braking position. The sleeve 10 is provided with a slot 14 which houses the straight side of a D-shaped locking clip 13. Hence adjustment on the brake shoes 2, 2 is achieved by moving the square cross-sectioned screw 9 inwardly or outwardly such that as the screw rotates, a corner of the square cross-sectional portion bears against the upright of the D-shaped locking clip 13 and forces it outwardly, the clip springing back into position against the then presented flat face of the screw until the desired adjustment is obtained. When the vehicle is to be parked, the screw 9 can be screwed sufficiently to force the shoes 2, 2 against the brake drum so that the brake is locked and undesired movement of the vehicle is prevented irrespective of any movement of the brake operating mechanism 20.
