Title: Improvements in fluid actuated reciprocating pumps
Inventor: BENT WILLIAM HAROLD
IPC: B60T8/40
Filed: 1957-12-03
Abstract: 904,001. Hydraulic brakes. DUNLOP RUBBER CO. Ltd. Nov. 21, 1958 [Dec. 3, 1957; April 2, 1958], Nos. 37559/57 and 10546/58. Class 103 (1). [Also in Groups XXVI, XXVIII and XXIX] A pump piston 26 is actuated by a motor piston 17 the motor chamber 19 being connected permanently to a source of vacuum and the chamber 21 being alternately connected to the vacuum source and atmosphere by the valve 22, the piston being moved on the suction stroke by a spring 33. The pump outlet is connected to an accumulator comprising a piston 43 slidable in a cylinder 44 and connected to a piston 39 subjected on one side to air pressure in the chamber 41. In a modification (Fig. 3, not shown), the motor is doubleacting and a quick-throw plate distributing valve is used to apply vacuum and atmospheric pressure alternately to opposite sides of the motor piston. In this embodiment oil pressure may be used to actuate the motor piston. The pump assembly 12 may be installed on a motor vehicle the engine inlet manifold or the lubricating oil pump providing the source of vacuum or oil pressure for the motor piston. The assembly 12 supplies liquid pressure for the braking system which includes a reservoir 16, power valve 10 and anti-skid valves 15. Specification 902,187 is referred to.
Patent GB-376297-A (GB)
Abstract: 376,297. Cash registers. NATIONAL CASH REGISTER CO., Ltd., 225, Tottenham Court Road, London.-(National Cash Register Co. ; Dayton, Ohio, U.S.A.) Feb. 7, 1931, No. 3968. [Class 106 (i).] Voucher-issuing.-In a key-set and operated machine the voucher strip is partly fed out of the casing and the machine becomes locked against use until the strip is manually drawn out to the full extent of the voucher. The voucher strip from a roll 195, Fig. 1, passes between rubber gripping blocks on a pair of arms 290, 291, pivoted at 295, and thence over a table and between feed and tension rollers 201, 202 to the knife-edge 199 and the outlet from the casing. The tension roller 202 is normally raised out of contact with the strip by a cam on the feed roller until feed occurs. The arms 290, 291 constitute a frame and are normally kept raised as in Fig. 3 by a stud 296 on a spring-controlled arm 297. When the key coupler rocks due to depression of a key a lever 158 moves clockwise about its pivot 159 and a dog 300 passes idly by the nose of the arm 297. On the return stroke however this arm is displaced to the right to free the frame which thereupon falls and withdraws a pawl 315 from a pin 316 on a latch 317. The latter then moves under spring action into the path of the end of lever 158 so that this, and therefore also the coupler and keys, are locked. During the descent of the frame 290, 291, the grip on the paper strip must be relaxed and for this purpose the rubber block 337, Fig. 11, is carried by a pair of links 325 slidably mounted on the frame and supported by a bell-crank 328 in turn controlled by a pawl 331. As the lever 158 makes its clockwise stroke the dog 300 rocks the bell-crank 328 to free it from the pawl 331 which then snaps behind it to hold it and the links 325 displaced, the block 337 consequently being kept separated from the fixed block 293. When the frame descends, on the return stroke of the coupler, the pawl 331 meets the stop 311 to free the bell-crank so that springs 338 may restore the links and the blocks again grip the strip in readiness for exercising the unlocking function when the strip is manually pulled forward. When it is desired to disable the voucher-issuing mechanism the usual knob may be turned and this positions a stud 368, Fig. 3, to act as a stop to maintain the frame raised and the latch 317 ineffective. If the frame should fall, through incomplete withdrawal of the paper strip, it may be manually replaced by manipulation of an external finger-lever. Specifications 10213/93 and 8678/98, [both in Class 106, Registering &c.], are referred to.
Patent GB-637099-A (GB)
Title: Improvements in or relating to high-frequency coil systems
IPC: H01F17/04
Filed: 1946-12-23
Abstract: 637,099. Inductances. PHILIPS LAMPS, Ltd. Dec. 23, 1946, No. 37681. Convention date, Oct. 27, 1943. [Class 38 (ii)] A high-frequency coil system, the inductance of which is adapted to be pre-set, comprises a tubular iron shell 5 (Fig. 3) magnetically open at least at one end a coil winding 1 contained within the shell and itself containing a hollow iron core 4 coaxial with the shell and an iron plunger 7 movably arranged within the hollow core so that the plunger partly projects from the core at the open end of the shell, whereby as the plunger is moved further out of the core the inductance of the coil is increased. The core and shell are supported by a flanged non-magnetic insulating body 6. This construction ensures that the iron losses, and consequently the Q of the coil system, are practically constant notwithstanding tuning adjustments. The plunger may be as long as, or short compared with, the length of the core. Fig. 6 shows a transformer comprising two such coil systems in a screening tube 9 and separated by an insulating spacer 8, the length of which almost exclusively controls the coupling between the coils. The various components may be preliminarily attached to one another by wirelike condensers 12, or an adhesive, to allow provisional adjustments on the transformer before fitting it in the tube 9. Specifications 450,286 and 637,098, [Group XL (c)], are referred to.

Title: Resistance-heated electric oven or kiln
IPC: A21B1/22
Filed: 1961-10-20
Abstract: 940,465. Mounting electric heating resistances in ovens or kilns. H. J. M. JERU. Oct. 20, 1961 [Oct. 27, 1960], No. 37729/61. Heading H5H. In an electric oven or kiln comprising heating resistances constituted by thin metal strips which form at least a part of the inner walls of the oven or kiln and support an outer thermally insulating lining, the resistances are supported by suspension means attached to an outer framework, the said means producing longitudinal tensioning of the resistances and allowing them to expand when heated. As shown in Fig. 1, heating elements in the form of parallel metal strips 1 are arranged transversely of the oven so as to form a vault 2 and side walls 3, 4. The strips are attached to a framework 7 by means of ties 6 and support a layer of thermal insulation 9 which may be constituted by comminuted refractory bricks covered with comminuted rock. Additional support for the strips is provided by an air inlet sheath 17, details of which are illustrated in Fig. 9 (not shown). The ties 6 are attached at their inner ends to stainless steel T-shaped members 10 (Fig. 4), the lateral arms 11, 12 of which support adjacent strips 1 with the aid of insulating tubes or rollers 13 and insulating washers 15, 16. Compensation for expansion of the strips is provided by springs 8 mounted on the members 10. Three alternative means for attaching the strips 1 to a supporting framework are described and illustrated in Figs. 5, 8, 10 (not shown). In a second example shown in Fig. 7, an oven is constituted by heating elements in the form of metal strips 70 mounted side by side on carrier bars 71 which are supported at their ends by ties 74, the upper ties incorporating springs 75 to produce tension in the strips. In a third example (Fig. 3, not shown), a kiln is constructed in a somewhat similar manner to the oven shown in Fig. 1, and differs mainly in the arrangement of the supporting framework. Means are also described and illustrated in Figs. 6a, 6b (not shown) for reinforcing the insulating material 9 (Fig. 1) by means of metal strips provided with projecting points which engage with the insulating material, pressure being applied to the strips by means of springs.

Title: Improvements in or relating to carbon electrode joints
IPC: H05B7/14
Filed: 1959-11-06
Abstract: 876,301. Furnace electrodes. SIEMENSPLANIAWERKE AKTIENGESELLSCHAFT FUR KOHLE-FABRIKATE. Nov. 6, 1959 [Nov. 7, 1958], No. 37770/59. Class 39(3). A carbon electrode joint includes two carbon electrodes 1, 2, Fig. 5, held in abutment by a double-conical screw threaded nipple 3 in screw threaded engagement with sockets in each of the electrodes, there being spacer means 4 located on, or at the apex of, a flank of the nipple thread, which flank faces away from the abutting faces of the electrodes, the other flank of the said nipple thread being thus forced into abutment with the adjacent flank of the thread in the socket of the electrode. Thus in one form one or more spacer members 4, Fig. 1, in the form of graphite or metal rings are located between the threads of the nipple and socket as shown. In a modification one flank of the thread teeth of the socket is widened so that a particular part of nipple thread is in abutment with both faces of the adjacent socket thread. Alternatively one of the threads of the nipple may be suitably widened. In a further embodiment a spacer 4c, Fig. 4, is cut into the tip portion of the nipple thread. This portion may break off under excessive stresses, but does not cause the electrode to burst and in order to ensure that breakage will occur at a predetermined location the spacer portion 4c may be provided with one or more undercuts 6.

Title: Scanning microwave waveguide aerial
Inventor: FULLER KEITH LEWIS
IPC: H01Q3/22
Filed: 1969-07-28
Abstract: 1,247,270. Aerials. MULLARD Ltd. 28 July, 1969, No. 37785/69. Heading H4A. A wideband aerial comprises an axially extending row of equally spaced radiating holes along a hollow waveguide, and an elongate dielectric member inside said waveguide. The length and breadth of each hole are substantially equal (e.g. they are circular or generally square) but their relative sizes may be systematically varied along the row, to reduce side lobes or otherwise modify the radiation diagram. The dielectric member effectively lowers the waveguide wavelength below the corresponding free space wavelength so that grating lobes may be controlled and eliminated, mathematical formula which must be satisfied being given. The dielectric member is made of a low-loss material, such as polystyrene, and may wholly or partially fill the waveguide under the array of holes, and be tapered for matching at the fed end. As described, the waveguide has a rectangular cross-section. A single row of holes may be provided along the centre line of a narrow wall (Fig. 4, not shown) or along a line parallel to the centre line of a broad wall (Fig. 5, not shown) or two rows of symmetrically staggered holes may be provided on lines parallel to, and at equal distances on each side of the centre line of a broad wall (Fig. 6, not shown). In all cases, the spacing between adjacent holes of a row is Xgo, where ygo = wavelength in the waveguide when the beam is perpendicular thereto. Dielectric material, generally having a dielectric constant higher than that of the material in the waveguide may be provided for the holes to increase the power radiated therefrom. This may take the form of a continuous slab outside the waveguide covering the holes (Figs. 8a, 8b, not shown) or of such a slab including stud-shaped pieces entering the holes (Fig. 7, not shown), or separate disc or stud-shaped pieces may be provided for each hole (Fig. 8c, not shown). Scanning by frequency modulation may be provided, and Specification 1,105,758 is mentioned.

Title: Improvements in or relating to pressure-sensitive adhesive tapes
IPC: C09J7/21
Filed: 1962-10-05
Abstract: 978,566. Adhesive tape. JOHNSON & JOHNSON. Oct. 5, 1962 [Oct. 6, 1961], No. 37789/62. Heading B2E. A pressure-sensitive adhesive tape 10 comprises a woven fabric backing 11, e.g. of rayon, regenerated cellulose or cellulose acetate having an adhesive coating 12 on one side from which hollow "pins" 14 of adhesive, made by forcing areas of the coating into the backing, project into the backing fabric, the walls of the pins being porous and act to filter air passing through the tape via these porous areas and also to bond together adjacent threads in the backing. The pins may be distributed throughout the tape including the edges at points not more than 0À25 inch from each other. Preferred adhesives, especially for rayon backings, are pressure-sensitive adhesive polymers of alcohol esters of acrylic acid and copolymers thereof with other copolymerizable monomers having strongly polar groups. The tape may be made by coating the backing with adhesive conventionally and then passing the coated backing through the nip of a pair of rollers one of which (18) is a cooled, hard supporting roll and the other (19) has blunt projections 20 which are preferably heated to about 280- 400 F. and which force the adhesive into the backing.

Title: Thermostatically controlled clutch
IPC: F01P7/08
Filed: 1957-12-09
Abstract: 863,318. Friction clutches. BORG-WARNER CORPORATION. Dec. 9, 1957 [Dec. 13, 1956], No. 38255/57. Class 80 (2). [Also in Group XXVII] A clutch between a driving-shaft 1 and a cooling fan 18 in a motor-car is engaged when increasing temperature causes a bimetallic strip 55 fast at one end in a cup 64 attached to the driving-shaft to screw a nut 43 along a thread 42 and engage a nylon buffer-ring 49 with the hub of the fan, the nylon ring then screwing the nut firmly into engagement with a clutch disc 31 having a lost-motion connection with the driving-shaft. Air from the motor car radiator passes through holes 66 to flow over the bimetallic strip 55, and the end 58 of the bimetallic strip is circumferentially adjustable with respect to the cup 64 in order that variation of the temperature at which the clutch engages may be effected. If the radiator cools down, and the bimetallic strip 55 accordingly tends to unscrew the nut 43, full clutch engagement is maintained until the car engine is slowed down, when the nut tends to unscrew, aided by the moment of the bimetallic strip, and turns the clutch disc 31 against the bias of a spring 27 to take up its lost motion with respect to the driving-shaft. This sufficiently reduces the force engaging the clutch to enable inertia effects to complete the unscrewing movement of the nut 43 for clutch disengagement.
