Patent GB-1179942-A (GB)
Title: Improvements relating to Mixing Valves.
Inventor: PARKINSON RICHARD G
IPC: F16K11/078
Filed: 1967-02-02
Abstract: 1,179,942. Valves. AMERICAN STANDARD Inc. 2 Feb., 1967, No. 46448/69. Divided out of 1,179,941. Heading F2V. A readily removable and replaceable plastics cartridge 50, which is adapted to contain all the moving parts of a hot and cold water mixing valve and to be mounted in the brass body 100 of the valve, comprises a generally U-shaped casing 55, a ceramic valve seat 70 fixed against rotational movement within the casing, a valve member 80 rotatably and slidably movable relative to the seat, and a pivot race 35 by means of which movement may be imparted to the valve member 80, the pivot race being retained within the casing by a cap 60, and the combined cartridge being secured to the body 100 by two bolts (49, Figs. 2-5, not shown). With the cartridge assembled in the body as shown, inlet passages (43a, Fig. 26, not shown) and 43b and outlet passage 45, all formed in the valve body 100, communicate with corresponding passages formed both in the casing bottom and valve seat, the two inflow passages terminating in proportioning recesses (75a) and 75b, both of which recesses are formed in that face of the seat which faces the valve member 80. In operation, rotation of the handle 33 about a pin 95 secured in the pivot race, places either one or both of the proportioning recesses in communication with the outlet passage 45 via a longitudinal recess 81 formed in the underside of valve member 80. Alternatively, rotation of the handle about an axis normal to the seat 70, causes similar rotation of the valve member 80 and hence proportioning of the relative volumes of hot and cold water passing from the proportioning recesses to the outlet 45. Leakage between the seat and valve member is inhibited by the provision of a resilient ring 65a in each of the inflow passages and a similar ring 65b in the outflow passage, such rings, together with the varying diameter of portions of each passage, serving to tightly bias the seat against the closure member.

Title: Cutting Device for Cigarette Rod or the like
IPC: A24C5/28
Filed: 1967-10-16
Abstract: 1,171,548. Continuous rod cutting guide. HAUNI-WERKE KÍRBER & CO. K.G. 16 Oct., 1967 [3 Nov., 1966], No. 46976/67. Heading A2C. A rod guide for a continuous cigarette rod cutting device of the type in which a cutting tube 9 is supported on the two sides of a cutting point by means of elongated spring members 4, 5 fastened to the cutting tube 9 and to support means 8 to allow for movement of the cutting tube 9 in the direction of the rod, is characterised in that the spring members 4, 5 are so arranged that orthogonal projections thereof in a plane perpendicular to the direction of the rod diverge in the direction towards the support means 8. As shown, the projections of the spring members 4, 5 diverge by an angle 7 of 180‹. This results in the substantial elimination of the latteral displacement of the reciprocated cutting tube 9 that would occur if the tube 9 were supported by two substantially parallel springs from the same side, and its replacement by a swing movement about the cutting point. The tube 9 consists of two parts 11, 12 comprising two cylindrical guide members 15, 16, approximately equal to a cigarette diameter in length, and tapered end regions 49, 50, the angles of taper 18, 17 being at least equal to the angle of swing of the cutting tube 9, e.g. 1‹. The springs 4, 5, which comprise spring packets of resin bonded glass fibre blades, are stressed one towards the other by oblique fastening to the support 8 by an angle equal to the angle of swing of the tube 9. Reciprocation of the support 8 is effected by a crank drive 19. Since the tube is slightly displaced on the support 8, Fig. 2, a small component of latteral displacement remains, but this is eliminated with an in-line method of mounting, (Figs. 5, 6 not shown). In another embodiment, the divergence angle is 120‹ which results in a considerable reduction, but not complete elimination of the latteral displacement of the reciprocating tube 9.

Filed: 1970-10-05
Abstract: 1322557 Automatic circuit breakers WESTINGHOUSE ELECTRIC CORP 5 Oct 1970 [6 Nov 1969] 47251/70 Heading H1N An automatic circuit breaker has closing springs 79, Fig. 1 charged by means of a motor 101 the output shaft 133, Fig. 3, of which has a roller arm 137 driven by the shaft to actuate the charging mechanism. The three-pole circuit breaker has a housing structure 7, Fig. 1, supporting the circuit breaker 9, the housing comprising a base plate 11, side plates 13 and a pair of metal centre plates 17. The bearing support for the shaft 133, Fig. 3, is fixed in one centre plate and, as the shaft rotates, the arm 137, carrying roller 139 engages the reciproeating pawl 78 which advances the ratchet 75 and crankshaft 71, thus tensioning the spring 79. A limit switch, coinciding with a missing tooth portion of the ratchet wheel, de-energises the motor drive when the spring is fully charged. In Fig. 2, the contacts 23, 21 are shown in the open position with the springs 79 charged. The latch 85, when pivoted anticlockwise, releases the roller 67 fixed to cam 51 and allows the springs to discharge and cause the contacts to close, through linkage 41, 33, 31. A latch 53 is released on rotation of the trip shaft 63 on the occurrence of an overload in any of the pole units. Compressed contact springs 93 and opening spring 99. Fig, 1, open the contacts and also cause rotation of shaft 35, which is common to all the units. If the springs 79 are recharged in the contact closed position, then, on tripping, the spring 59 connected to the latch 53 resets the circuit breaker so that immediate reclosure is possible. Alternatively, the springs 79 are recharged in the tripped position by means of the motor drive, this also resetting the latch 53. Manual operation mechanism is also provided for tensioning the springs 79.

Filed: 1973-10-15
Abstract: 1445891 Moulding building elements from clay R S CLARK 15 Oct 1973 47949/73 Heading B5A A method for the production of building elements, e.g. panels or pipes from clay comprises grinding the clay to give particles of a size corresponding to the output of a hammer mill set to produce pieces of maximum dimension 1¢ inches, filling a graphite mould having walls at least ¢ inch thick with the ground clay, heating the clay in the mould for up to 2¢ hours to a temperature of 1800-2500‹ F. to form the clay into an adherent mass, commencing cooling of the mould and the clay mass substantially immediately the said temperature is reached, and removing the mass from the mould. The mould is protected from oxidation during heating, e.g. by using a reducing atmosphere where the mould is heated in a kiln, or by wrapping in ceramic fibres where induction heating is used. The clay used is preferably montmorillonite, and the product has a vesicular structure. To produce panels, the mould is formed from graphite slabs; to produce pipes, inner and outer graphite pipes are used to define an annular mould cavity. To produce a decorative effect on the moulded article, sand or quartz may be scattered on the mould surface before charging of the mould, and become embedded in the moulded body.

Abstract: 1,059,252. Comparison photo-meters photo-electric calibration. INTERNATIONAL POLAROID CORPORATION. Nov. 25, 1965 [Dec. 9, 1964], No. 50196/65. Headings G1A and G1P. [Also in Division G2] A method of calibrating a comparison photometer in a camera in which method the diaphragm blades 13, 14, double-apertured at 16, 17, are manually adjusted until photo-metric balance is obtained at the target 27 which is illuminated on the one side by external light through aperture 17 and on the other side by light from standard lamp 28, the fixed speed shutter 24 is then operated to cause light through aperture 16 from objective 12 to fall upon a light integrating device in the film place 23 whereby the overexposure error is measured, and a neutral density light attenuator is then inserted between lamp 28 and target 27 to give correct exposure on a film of selected speed when the photo-meter is re-balanced and the shutter operated. The light integrating device may be a photoconductor in series with a capacitor, and a step voltage is applied to the circuit when the shutter opens, the voltage across the capacitor when the shutter closes being a measure of the time integral of light falling on the photo-conductor. Eye fatigue due to repeated photo-meter balancing is avoided by monitoring the photo-meter target by means of a television camera and kinescope to provide the operator with an enlarged view of the target with increased brightness or contrast. Alternatively, the balance condition may be displayed on a meter (58) using the circuitry shown schematically in Fig. 7 (not shown).

Title: Improvements in or relating to a Device for Automatically Supplying Rods to Spray Guns
IPC: B23K9/12
Filed: 1967-11-06
Abstract: 1,191,912. Spray producers. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 Nov., 1967 [24 Nov., 1966], No. 50399/67. Heading B2F. A device for automatically supplying rods to a spray gun comprises a feed device, a presenting device, a transfer device, a thrust device, a pneumatic detector and a timing device responsive to the detector to control successively the transfer device and the thrust device. Rods B are stored vertically above each other in the feed device which comprises two parts 6a, 6b mounted on a support 1. Below the feed device is a longitudinally grooved presenting device 3 provided with an inclined face (3c) (Fig. 3, not shown), on which each rod rests in turn. As a rod BC is consumed in the spray gun C, air from a conduit 28 enters an opposed inlet 17 to a pneumatic detector 16 which causes two jacks 13a, 13b to operate to push the next rod (B1) off the inclined surface (3c) of the presenting device into the groove (4) which is in alignment with the spray gun. The detector 16 also triggers two time-delay devices 21, 22 such that as the trailing end of the preceding rod BC enters the spray gun it is wetted by a jet of water from a nozzle 18 operated by the delay device 21. Then the delay device 22 passes air to a thrust nozzle 19 via a distributor valve 20, to exert an axial thrust on the rod (B1) now lying in the groove (4) of the presenting device. Some of the air to the thrust nozzle also operates a time-delay device 23. As the rod passes to the spray gun the air to the detector through inlet 17 is interrupted, the jacks 13a, 13b retract under spring action to allow the next rod to drop from the feed device on to the inclined surface (3c), the water spray ceases and the thrust ceases. Thereafter the delay device 23 operates to reset the distributor valve 20 to its original position ready for the next cycle. The rods are fed through the spray gun, by rotating rollers M1, M2.
