Title: Improvements in heating systems
IPC: F24D17/00
Filed: 1921-08-13
Abstract: 169,961. Mills, B., Row, R. R., and Davis, H. C. Oct. 7, 1920, [Convention date]. Heating liquids.-Viscous substances, such as congealed or thickened liquids, e.g. heavy oils, asphalt, molasses, &c., in storage tanks 14, 14<a> are heated so as to render them more mobile by circulating in the first instance a certain amount contained in a smaller tank 1 by means of a. pump 2 through a coil 6 surrounded by steam in a jacket 7 by way of pipes 3, 5, 10. When this amount is fluid, by adjustment of cocks, a proportion of the hot fluid is introduced through pipes 9, 13 into any or all of the main storage tanks the circulation being completed by the pipes 15, 16 or 16a. At a later stage distant parts of the tanks 14, 14a may be heated by introduction of hot fluid through pipes 22, 22<a>. Fluid for use is taken from the tank 1 which is kept warm when the installation is fully working by a small proportion of circulating liquid controlled by the cocks 4, 11. The system can be applied to the unloading of tank cars. The Specification, as open to inspection under Sect. 91 (3) (a), referred to the use of a liquid in the small tank different from that in the storagetank. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to reversing valves
IPC: F01L15/08
Filed: 1960-06-20
Abstract: 948,454. Liquid-pressure engines. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. June 20, 1960 [June 22, 1959], No. 21546/60. Heading F1A. A valve for automatically reversing the supply and discharge of pressure liquid to and from the opposite sides of a double-acting piston 2, Fig. 1, comprises a stationary housing 8 having a pressure supply port 19, exhaust ports 17, 21 and ports 18, 20 connected to cylinder spaces 12, 13 respectively, a valve body 22 slidable within the housing co-operating with the ports and a valve control member 7 operably connected to the piston 2 and having a collar 26 slidable in an axial bore in the valve body. To maintain the stroke of the piston 2 substantially constant irrespective of variations in engine load a port 30 controlled by a pressure-responsive throttle element 36 is formed between lands 23, 24 of the valve body. The throttle element 36 loaded by a spring 39, Fig. 4, is subjected at opposite ends to supply and exhaust pressures. In the position shown in Fig. 1, the piston 2 is nearing the end of its rightward stroke and an abutment 4 on the piston rod 3 has engaged a lever 6 to move the control member 7 leftwardly to open a space 27 to the left of the collar 26 to exhaust through a groove 31 and a space 28 to the right of the collar 26 to supply pressure through the port 30 whence the valve member 22 immediately moves to the right to reverse the valve connections to the cylinder spaces 12, 13. The piston 2 now commences to move leftwardly until the abutment 4 engages a lever 5 to again reverse the control member 7 so that the space 28 is opened to exhaust through a groove 32 and the space 27 to pressure supply. Should for any reason, e.g., increased loading on the piston 2, the supply pressure decrease, the throttle element 36 will move rightwardly to increase the opening of the port 30 to compensate for any time lag which might otherwise occur in reversing the valve member 22. Conversely an increase in supply pressure would reduce the opening of the port 30. The valve member 22 shown as a piston valve, could if desired, be replaced by a flat slide valve and the throttle element 36 operated by a diaphragm subjected on opposite faces to exhaust and supply pressures. Specification 858,265 is referred to.

Title: Infinitely-variable adjustment device and brakes incorporating such devices
Inventor: BUTLER HENRY JAMES
IPC: F16D65/54
Filed: 1957-07-10
Abstract: 883,416. Friction clutches; linkwork. DUNLOP RUBBER CO. Ltd. June 25, 1958 [July 10, 1957], No. 21806/57. Classes 80 (2) and 80 (3). [Also in Group XXXIV] Infinitely-variable adjustment devices, to take up wear especially in brakes and clutches, comprise two relatively movable members associated with opposed flat surfaces, wedges located in pairs between said surfaces and the sides of a housing containing the two said members, and springs to press the wedges into frictional engagement with the surfaces so that relative movement occurs in one direction, and jamming in the other direction. In a disc brake having friction pads 13 moved against disc 1 by pivotal movement of pressure plates 3 and 4 about pins 10, the pressure plates 3 and 4 have recesses 17 therein receiving the ends 18 of arms 19. Under normal conditions, the friction pads 13 are spaced away from the disc 1 by a gap 21 and the clearance of the ends 18 in recesses 17 is such as to allow this movement. If, however, due to wear of the pads 13, the spaces 21 are increased much above the normal, the application of the friction pads against the disc causes deformation of the arms 19 to impart to them a permanent set. Release of the brake-applying pressure allows the arms 19, by reason of the clearance of ends 18 in recesses 17 to reflex to reset the spaces 21. The arms 3 and 4 are prevented from moving apart by the one-way locking device comprising sprags 15 in the housing 14 which engage the end of the operating rod 6, which is pivoted to the lever 7. Specifications 708,748, 709,305 and 883,417 are referred to.

The plates are then connected together by welding, as shown at 6, Fig. 1, or by riveting or additional bolts. The fluid-tight nature of the structure may be maintained by welding around the base of the nuts 15. In the construction of a tank which is formed in an excavation in the ground as shown in Fig. 6, the outer shuttering 16 comprises a removable wood or metal framework, and the inner shuttering consists of metal plates 4, 5 connected to the reinforcement 2, 3, the opposite metal plates being connected by guy cables 17 attached to apertured projections 11 on the nuts 15. The projection 11 on the nut 15 is provided with an additional aperture 14 to receive the end of the bolt 7. All the plates constituting the shuttering may be first erected and the concrete then cast, or additional plates may be added as the concrete is cast. The plates may be vibrated during the casting operation. When the metal plates are left in position, they may be covered with a layer 21 of mortar, concrete or other material reinforced by lattice work or other material 20 secured to the nuts 11 as shown in Fig. 7. An additional protective layer 22 may be provided on the layer 21. The metal shuttering may be provided on either the inner or outer side of a structure or on both sides. The ties 10, 13 may be connected to the tension or compression reinforcement or to the stirrups connecting them. When the shuttering is intended to be removable, the metal members 12a are bolted to the plates 4, 5, and the plates are bolted together by ordinary bolts, in addition to the bolts 7.

Title: Programmable graticules
IPC: F41G3/06
Filed: 1975-03-18
Abstract: 1496155 Lighting MARCONI CO Ltd 18 March 1975 [16 May 1974] 21862/74 Heading F3C [Also in Divisions G4 and G2] A programmable graticule comprises two arrays of light emissive diodes each adapted to produce a display in the form of parallel stripes of light, means for selectively energizing the stripes in the two arrays, and means for optically combining the light emitted by a stripe from each array to produce an illuminated cross. The arrays may be adapted to produce stripes by virtue of using elongated light emmissive diodes, or the elongation may be achieved by a cylindrical lens in front of each array. The selected stripes from the two arrays are combined by a halfsilvered or dichroic mirror to form the cross. The cross produced is combined in a further such mirror with the view through the view finder or gun sight of a weapon. A "1" bit is inserted, each cycle, into a clock-pulsedriven shift register which scans the anodes of the diodes of each array, the two arrays together via drive transistors, each array having a respective switching transistor to which the cathodes of its diodes are connected in common, the required diodes being illuminated each cycle by suitably timed enabling pulses to the switching transistors.

Title: Improvements in electric motors
IPC: H02K17/26
Filed: 1921-08-18
Abstract: 172,603. Yamamoto, T., and Kawarada, M. Dec. 7, 1920, [Convention date]. Alternating-current motors; exciting.-In order to increase the starting torque of a synchronous motor which is started as an induction motor with its secondary winding S connected in series with a continuouscurrent series generator A, the rotor is also provided with a high resistance squirrel cage.winding K, Fig. 2. The rotor of the induction motor and the armature of the series generator are coupled mechanically. In the case of a motor having a three-phase secondary winding S, in addition to providing the rotor with a squirrel cage winding, or instead of doing so, the field winding of the series generator is divided into three separate sections F<1>, F<2>, F<3>, connected each in series with one of the three-phase windings, the connections of one of the sections being reversed so that the three field-winding sections may act cumulatively. The field winding acts as a high reactance winding and limits the current at starting. Starting resistances R, Fig. 1, may be included in the secondary circuit. These resistances R may serve for voltage regulation when the motor has reached synchronism. In a modification, the starting resistance instead of being inserted directly in the secondary circuit is connected to a coil coupled inductively to the field windings F<1>, F<2>, F<3>.

Title: Improvements relating to the interfitting of close-fitting machine parts such as cylinder linings
IPC: F16J10/04
Filed: 1933-08-04
Abstract: 423,518. Jointing by shrinking. EDMUNDS, D. H. O., The Hermitage, Thames Ditton, Surrey, DOBSON, C. R., Swiss Cottage, Harold Wood, Essex, and SOLVENT PRODUCTS, Ltd., Bush House, Aldwych, London. Aug. 4, 1933, No. 21942. [Class 83 (iv)] [See also Group XIII] In a process for assembling close-fitting machine parts by shrinking the inner part by means of " dry ice," commercial alcohol cooled by " dry ice' is used as a lubricating medium and for the prevention of the formation of hoar frost, and may also be used as the medium for shrinking the part. The shrunk conditions of the inner part may also be maintained during insertion into the outer part by means of an internally fitting device serving as a reservoir for intense cold. The process is stated to be applicable to the assemblage of close-fitting cylindrical parts of guns, locomotive wheels, ball bearings, bushes, &c., and particularly hardened or toughened steel liners in internal-combustion engine cylinders. The internally fitting device may consist of a close fitting perforated metal cage containing " dry ice " or a thin metal container filled with " dry ice "-cooled alcohol, and remains within the inner part until it has been placed in position. For cylinder liners, each liner is preferably cooled by immersion in a bath of cooled alcohol or in an externally cooled container and is transferred as a unit with its inner cooler to the cylinder, after which the inner cooler is withdrawn. The cooled liners may be contained in a cabinet and moved by a transfer gear to a succession of cylinders, or the cabinet may travel or rotate to bring each liner into position for transfer. The cabinet may consist of a heat-insulated chamber containing a number of boxes kept cool by " dry ice," the liners with their internal coolers being located in the boxes, and the liners may be lowered directly into cylinders arranged vertically beneath. The liners may be lubricated by means other than cooled alcohol. Each bore may contain a quantity of alcohol such that when the liner and internal cooler are placed therein, the alcohol will rise about the liner to lubricate it during insertion and prevent the formation of hoar frost. Small bushings and rings may be transferred from the cooler by means of a metal plug frictionally fitting inside the rings and provided with an insulating handle, the action of dipping the plug into the alcohol serving to cool it so that it will maintain the ring shrunk during transfer.

Abstract: 706,184. Pressure gauges. KENT, Ltd., G. Aug. 30, 1951 [Sept. 6, 1950], No. 21988/50. Class 106 (2) A differential fluid pressure gauge wherein variation of fluid pressure is translated into variation of height of a liquid column comprises two liquid vessels with liquid connection between their lower parts, means for applying each differential pressure to the upper part of a vessel, means for fixedly mounting one vessel and a resiliently flexible cantilever for mounting the other vessel such that the extent of movement thereof is a measure of the weight of the liquid column therein. A vessel 1 mounted on a fixed support 2 is connected by a resilient flexible pipe 3 to another vessel 4 solely supported by the pipe 3 and a similar pipe 5 which is adapted to feed one differential pressure to the top of vessel 4 the other being fed by a pipe 6 to the top of vessel 1. A pipe 7 cross-connects pipes 5, 6 and cocks 8, 9, 10 are fitted in pipes 5, 6, 7 and an air release valve is fitted to the top of vessel 4. A flange 11 on the side of vessel 4 is connected by a link 12 with a pointer 13 moving over a scale 14. A sealing liquid 15, e.g. oil, mercury or water, fills pipe 3 and partially fills vessels 1, 4. In use the cock 10 is opened to equalize the pressures in the vessels and the pointer indicates zero, then the cock 10 is closed and the differential pressures in the vessels causes fluid to move in or out of vessel 4, changing its weight and more or less deflecting the pipes 3, 5 so that the pointer 13 moves to indicate the differential pressure on the scale 14. Alternatively the deflection of the pipes may be translated into movements of integrating recording or controller mechanism. The flexible support for the vessel 4 may comprise flat or other section leaf springs or a coil spring either distinct from the ducts or pipes conveying fluid or combined therewith, e.g. a coil spring of piping for the passage of fluid.
