IPC: F16F9/348
Filed: 1962-03-20
Abstract: 981,915. Hydraulic shock absorbers. ARMSTRONG PATENTS CO. Ltd. April 19, 1963 [March 20, 1962], No. 10569/62. Heading F2S. A telescopic hydraulic shock-absorber has a cylinder 10 with a valve-plate 36 in the foot valve 30 which admits fluid from a reservoir into the cylinder and a piston 16 with a valveplate 40 which permits flow through the piston towards the foot valve 30, each valveplate being associated with a leak-notch which permits flow in a direction opposite to that through the valves. In Fig. 1 the leak-notches for the two valves are indicated at 46 and 48. That at 48 may be replaced by an axial channel in the piston-rod 20 opening in front of the piston-head and venting through a short radial channel into the space behind the piston (Fig. 2, not shown). Figs. 3 and 4 show alternative foot-valves 60 and 70 in which, in addition to the leak-notches respectively at 70 and 80, means are provided to relieve excess pressures on the valve-plates 66 and 86. In valve 60 any excess pressure will cause the centre of the valve-plate 66 to depress so that fluid can escape through the central aperture 67 into a recess 63 having an outlet 72. In valve 70 the valve-plate 86 has holes 88 which are normally masked by an inner plate 82 having ports 84. In the latter instance excess pressure depresses the plate 82 so that fluid can escape through to a radial groove 78 in the valve.

Title: Automatic correction circuit of the mean dc level of electrical signals
IPC: H04L25/06
Filed: 1961-03-23
Abstract: 910,064. Pulse level-correction circuits. STANDARD TELEPHONES & CABLES Ltd. (Bell Telephone Manufacturing Co. S.A.). March 23, 1961, No. 10698/61. Class 40 (3). A circuit for the correction of mean the D.C. level of pulse signals comprises an amplitude comparator circuit G and a delay V. Pulses 18, 19, Fig. 2, have a D.C. level b which differs by #E from the correct level a. When such pulses are applied to the comparator G capacitors 4, 6 charge to potentials (E/2+ #E) and (E/2 - #E) respectively. Discharge is arranged to be slow, and the potential formed across resistor 10 is thus #E. This potential is fed to one side of a bi-stable device 17, e.g. a telegraph relay. The pulses 18, 19 are also passed to a delay circuit V which delays the pulses by half a pulse period before being passed to the other side of the telegraph relay. In this manner the relay changes from one state to the other at the points of intersection with the true zero level.

Title: Improvements in or relating to gaskets
IPC: B65D53/02
Filed: 1962-03-20
Abstract: 955,439. Joint-making packing. W. R. GRACE & CO. March 20, 1962 [April 14, 1961 (2)], No. 10705/62. Heading F2B. [Also in Division B8] A gasket e.g. for a crown or screw cap comprises a foamed plastic disc 1 e.g. of foamed polystyrene, with an outer elastomeric coating 2 e.g. of puffed polyvinyl chloride; the disc is of greater rigidity than the coating and provides a support therefor, and when the cap 3 is pressed on to a bottle 4 the coating provides a seal whereas the disc is compressed more or less permanently to a thickness substantially the same as, or less than, that of the coating. Instead of a disc, the foamed plastic may be in the form of a ring to the outer circumference of which the elastomeric coating is applied. The gaskets may be cut from a pre-formed rod of foamed plastic coated with an elastomeric substance. The latter may be applied by dipping or by placing a preformed sleeve of elastomeric material over the rod. The rod may be extrusion moulded and then cut or ground to size; an adhesive coating may then be applied to which an elastomeric coating is applied by extrusion. The gasket of Fig. 7, for sealing a porthole in a vacuum chamber, comprises a supporting member 11 of foamed plastic to which are attached sealing elements 12. The member 11 is more rigid than that of the elements 12 and serves to retain the shape of the gasket during its handling. It has bolt holes 13 and may be sliced from a block of foamed plastic which has been cut to the desired shape, drilled, and dipped into rubber latex.

Title: Improvements in and relating to baking ovens
IPC: A21B1/46
Filed: 1932-04-14
Abstract: 401,687. Bakers' ovens. POINTON, J. E., BEANES, W. H., Westwood Works, Peterborough, and BAKER PERKINS, Ltd., Hythe Road, Willesden, London. April 14, 1932, No. 10735. [Class 51 (ii).] In a baker's oven of the endless-conveyer type in which the goods are fed to the oven below, and are baked in, an atmosphere of steam, the flow of steam within the oven is controlled so that it follows the course of the conveyer, and escapes over the baked goods. As shown in an oven in which the conveyer moves in a number of superposed laps, feeding and discharging take place where the conveyer passes over chain wheels 17 arranged outside the oven proper but within a housing 18 having a door 19. Adjacent the wheels 17 is a fixed baffle 24 having a slidable counterweighted extension 23 which regulates the level at which the steam escapes. The return lap of the conveyer passes to the charging and discharging station over chain wheels 20, and the feed lap passes first downwards and then upwards along guide rails 21, at the lower part of a curved baffle 22, a pit or cavity 16 being provided to afford clearance for the swinging trays. Steam is supplied at various points through nozzles 34, and the baffles 13 between the laps and the curved baffle 22 ensure that the steam will follow the same course as the conveyer and will escape over the outgoing goods. The extension 23 of the fixed baffle 24 is formed with stops which contact with a fixed angle bar when the extension is in its lowest position, and on this bar are screwed studs which press the moving and fixed parts together to make a steam-tight joint. Specification 314,456, [Class 51 (ii), Furnaces and kilns for applying &c.], is referred to.

[Class 100 (ii).] In a printing-machine having multi-plate printing-cylinders, clamping-devices are provided which clamp the plates yieldingly and whereby the plates after being clamped may be independently adjusted in position upon the cylinder in the lateral and circumferential. directions. The plate A is gripped by clamps b, c, slidably mounted on a shaft d which is arranged in a groove a<3> in the cylinder parallel to its longitudinal axis. The inner end of the shaft d is screw-threaded to engage in a fixed block a<4>, a collar d<2> being secured on the shaft to limit the movement of clamp c in this direction, and the outer end of the shaft projects beyond the usual clamping-up plate e, passing freely through a sleeve e<1> which is adjustably mounted in the plate e and serves for the adjustment of a helical spring f mounted on the shaft d and bearing against the sleeve e<1> on one side and against the outer clamp b on the other. 'The printing-plate A is clamped by movement of the plate e. when the clamp b is pressed against the plate A by the spring f, the pressure being transmitted by the printing- plate to the clamp c which is held in adjusted position by the collar d<2>. The inner plate B is provided with similar clamps b<1>, c<1>, mounted on a shaft d<1>, pressure from the spring f<1> being transmitted to the outer clamp b<1> through a sleeve g. Lateral adjustment of the plates A, B is effected by rotating the shafts d, d<1>, whereby the two clamps on each shaft move simultaneously, without change in their relative positions. For effecting the circumferential adjustment of the plates, a shaft h is provided and carries at its outer end a loose sleeve i. Adjusting stops j, k are provided for the plates A, B, respectively, and each stop is formed with a diagonally-disposed groove j<2>, k<2>, in which is received a correspondingly disposed rib, provided upon an adjusting block l, m, which are screw-threaded to engage the sleeve i and the shaft h, respectively. Upon rotation of the sleeve i, the block l is moved axially to advance or withdraw the stop j, and similar rotation of the shaft h adjusts the stop k. Stops may be provided at both edges of the plates. Other plates may be carried by the right-hand half of the cylinder, the clamping and adjusting mechanisms being positioned for operation from the other end and being staggered in position to clear the mechanisms for the plates A, B.

Title: Improvements relating to input apparatus for pattern recognition devices
Inventor: FROGATT ROBERT JUSTIN
IPC: G06V30/146
Filed: 1968-03-06
Abstract: 1,270,801. Pattern recognition. EMI Ltd. 21 May, 1969 [6 March, 1968], No. 10816/68. Heading G4R. Input apparatus for a pattern recognition device comprises a first pick-up tube (e.g. vidicon or flying-spot scanner) for scanning a predetermined area, a plurality of further pick-up tubes for scanning different portions of the predetermined area, and means responsive to signals from the first pick-up tube for selecting a region of the predetermined area and for passing to the pattern recognition device signals from the or each of the further pick-up tubes scanning the selected region. As described, the pattern is postal code on a letter to be sorted. At a pre-scan station, a pick-up tube feeding an analyser locates the lower right portion of the address (which presumably includes the postal code) and selects one (or more) of a matrix array of pick-up tubes at a second station to which the letter is conveyed to feed the scanned signal to a pattern recognition device controlling a sorter. The fields-of-view of the pick-up tubes in the matrix may overlap so that the whole postal code occurs within the field of one of them. Embodiments are described using lenses, mirrors, screens and flash-tubes to reduce the number of pick-up tubes for a given number of selectable fields, by energizing a selected flash-tube as well as selecting a pick-up tube, a given tube seeing more than one field of the letter but only one of these being illuminated. In the case of flying-spot scanners, selection of a flash tube is replaced by selection of a photocell.
