Abstract: 1,092,848. Watches. E. PIQUEREZ. June 29, 1966 [July 14, 1965; Jan. 31, 1966], No. 29106/66. Heading G3T. A watch case comprises a case band 1 and a watch glass 13, below which is mounted a toothed ring 9 capable of being rotated by a control member consisting of a knob 4 and a rod 5 which bears a pinion 7, the control member being movable from one position in which it is non-rotatably locked to another position in which it may be rotated so that the pinion rotates the ring. The rod 5 is mounted in a tube 3 driven in a hole 2 in the case band 1. Projecting flutes 11 on the rod engage flutes 10 on the tube thereby locking the knob against rotation. On pulling the knob 4 outwards until a shoulder 12 of the rod abuts the tube 3, the flutes are disengaged so that the knob may be rotated which in turn rotates the ring 9 via the pinion 7. The ring carries a guide-mark with reference to which the hands of the watch may be set. In a modification, Fig. 5 (not shown), the flutes (18) on the tube (20) are formed on the end (19) of the tube close to the knob (14) and engage flutes (17) formed on a threaded sleeve (16) of the knob into which the rod (15) screws. In a second modification, Fig. 6 (not shown), the flutes (51) are formed on the external surface of the tube and engage flutes (41) on the inside of the outer sleeve (101) of the knob (24).

Title: A vacuum switching apparatus
Inventor: OHWADA KATSUO
IPC: H01H33/666
Filed: 1969-06-10
Abstract: 1,263,375. Vacuum switches. TOKYO SHIBAURA ELECTRIC CO. Ltd. 10 June, 1969 [10 June, 1968; 10 Sept., 1968], No. 29236/69. Heading H1N. A vacuum switch 3 has an opening spring 19 and a closing electromagnet 22 whose forces are so related to the pressure differential tending to close the contacts, that, if the evacuated vessel should be broken with the contacts open they cannot subsequently be closed, and if with them closed they are not opened until the electromagnet is de-energized. The spring 19 and magnet 22 act in opposition upon a lever 15 pivoted at 16 and which acts on an extension 14 of an operating rod 10 to open the contacts and on a spring 10 to provide additional contact pressure. The initial attractive force of the magnet is less than the force of spring 19 and therefore prevents closure unless the differential pressure assists closing. The force of the magnet in engagement with the armature 18 is greater than the force of spring 19 so that the contacts are not opened if the differential pressure disappears.

Abstract: 813,509. Multiple-ply paper-board-making machines &c ST. ANNE'S BOARD MILL CO. Ltd. Oct. 8, 1956 [Oct. 14, 1955], No. 29256/55. Class 96. Pulp supplied from a flow-box 12 to a travelling wire-cloth 1 is formed into a web 14 and may be inverted whilst it is carried between the wire 1 and a coacting wire 4, the wire 1 being then directed by rolls 6 to bridge over a second flow-box 11 feeding a layer of pulp to the wire-side of the web 14, the wires converging so that water is expressed through the wire 1, its momentum carrying it up a shoot 9 and into a channel 13 for removal. Further plies are likewise formed, on opposite sides of the composite web, by successively inverting the web and wires and raising the wires 4 and 1 alternately to accommodate further flow-boxes 11. Formation may be aided by suction zones 3A in rolls 3. In modifications: (1) suction boxes are used under horizontal runs, or adjacent vertical runs of the wires etc.; (2) each reversal of the wires occurs about a single roll 3 and pulp is fed into spaces where the wires converge at the beginnings of horizontal runs; (3) two supplies of pulp are arranged at each of a number of horizontal runs; or (4) there may be one supply at the middle and one at the beginning of a run; and (5) supplies may be above and below a single horizontal run. Webs thus made have longer fibres at and near their outer surfaces than those of the remainder of the outer plies.

Filed: 1930-10-02
Abstract: 358,271. Slicing-machines. GOMEZ, A., 17 bis, Rue Charles Lecoq, Paris. Oct. 2, 1930, No. 29529. Convention date, Oct. 3, 1929. [Class 28 (ii).] Apparatus for slicing and distributing soap, cooked meats, and the like, of the kind in which a reciprocating cutter is arranged under or at, the end of a casing containing the soap &c., is characterized by the provision of a ring-shaped recessed cutter which receives the material in the recess and cuts off a slice by the action of its inner upper edge. In the illustrated construction a block of soap falls by gravity in the casing 2 so that its lower end abuts against a hand-operated pivoted member 9. In one extreme position of this member the block registers with the recess 13 so that it enters therein and contacts with an adjustable stop 17. Movement of the member to its other position then causes the upper inner cutting-edge -of the recess to remove a slice from the block, the thickness of which is regulated by the position of the stop. The top of the casing is closed by a plug 3 provided with bayonet slots 4, and a cap 6 which springs over the balls 5. The casing may be arranged horizontally and the material fed by means of springs or counterweights, or by a mechanical intermittent feed operated by the movement of the cutter.

Title: Improvements in or relating to water tube steam generators
IPC: F22B35/10
Filed: 1931-10-27
Abstract: 375,178. Fluid-actuated valves. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. Oct. 27, 1931, No. 29788. Convention date, Nov. 12, 1930. [Class 135.] Valves controlled by pilot or relay valves.-In water-tube boilers in which the working medium is fed both to the inlet end of a continuous tube from the end of which steam is discharged and also at an intermediate point or points, both supplies are regulated in accordance with the outgoing steam temperature by inter-related means whereby the latter tends to be regulated first and movement of one valve-actuating means affects the conditions determining the actuation of the other valve. In operation the additional and main supplies are adjusted in sequence, the additional supply then being readjusted to its normal value ; under abnormal changes however the regulators function simultaneously. The outlet pipe 8 of a boiler comprising a tube system 5, 7, in which superheating commences at the point 6 and with main and intermediate feed inlets 4, 13 regulated respectively by throttles 14, 15 has a temperatureresponsive control 16 influencing the pressure of liquid in a column 17 which in turn controls the pistons 22, 23 of two actuating devices 18, 19. The flow of pressure fluid admitted through ports 20, 21 to servomotors 39, 27 and the discharge therefrom through outlets 47, 46 are governed by the position of the pistons. On a rise of temperature in pipe 8, the pistons rise, port 21 opening first as the central portion of piston 23 is shorter than that of piston 22. Throttle 15 is accordingly opened and feed supplied to the intermediate point 13. Movement of the throttle valve stem however rocks a lever 29 about a pivot 30 and causes a linked lever 32 to compress a spring 25 tending to lower the piston 23. Pressure on the spring 24 of piston 22 is at the same time relieved through the agency of links 33, 36 and levers 35, 37 and the parts are so chosen that when throttle 15 is opened a given amount piston 22 rises sufficiently to bring servomotor 39 into operation to open throttle 14 and so increase the main feed. Pressure on spring 24 is now increased through the action 'of levers 41, 37, and by means of rod 44 lever 32 is turned about a pivot 45 to compress spring 25 thus depressing piston 23 and connecting servomotor 27 with the discharge port 46, throttle 15 returning to its starting position. When an abnormally rapid rise of temperature occurs the increased pressure in pipe 17 raises both pistons 22, 23 to increase both feeds practically simultaneously. In the case of several intermediate feeds the supply nearest the boiler outlet is preferably regulated first.

Abstract: 1,117,088. Dispensing articles. TATEISI ELECTRONICS CO. 14 July, 1965 [20 July, 1964], No. 29827/65. Heading A4T. Vending apparatus in which the validity of credit cards is checked comprises means for receiving a card and reading its identification number to produce signals corresponding thereto, means for dispensing an article selected by a purchaser and producing a signal corresponding to its price, recording means receiving the number and price signals, and AND elements connected to means for transmitting said number signals to said recording means such that said number signals are applied to the input to one of said AND elements when said number is one memorised as invalid. The genuineness and date validity of the card may also be checked. The credit card shown in Fig. 2 has a label 12 containing magnetic material to distinguish the card from forgeries. It also has an opening 19 whose position indicates period of availability and two openings 17, 18 representing the identification number. Signals from a detector 23, Fig. 5, which detects the magnetic material and from photosensitive element 42 which detects opening 19 pass through an AND element 92 and via INHIBIT element 107 to the dispensing mechanism. Identification signals from photosensitive elements 30 to 41, which read the position of openings 17, 18, pass through lines 50 to 61 to a recorder. Invalid numbers are memorised by connecting diodes e.g. 121 to 124 across lines 50 to 61 to lines 104 and 105 which connect to the input of an OR element 111. If an invalid number is read, an inhibit signal passes via the OR element to element 107 so that the article dispensing mechanism will not be actuated.
