Title: Improvements in methods of moulding rubber and similar materials
IPC: B29C37/00
Filed: 1952-03-31
Abstract: 709,378. Moulding rubber tyres &c. UNITED STATES RUBBER CO. March 31 1952 [June 21, 1951], No. 8109/52. Class 87 (2) During the shaping of rubbery material, it is subjected to stresses in a direction transverse to the residual stresses, the transverse stresses being of such a magnitude that the effect of the residual stresses is reduced. As applied to the moulding of tyres, strips of rubber 13. 14, Fig. 1, are extruded from a twin extruder 10, 11 and the strips cut longitudinally into two parts 18, 19, Fig. 2, by a rotary knife 16, and transversely into tyre lengths by a rotary knife 21. The part 13 is made of abrasion resistant material and the part 14 of crack resistant material. The ends of a length are spliced together to form annular bands which are then stretched and applied to a core 28. The bands are then moulded under heat and pressure between mould halves 24, 25, Fig. 4, to form of a tyre. The mould is heated by passing a heating medium through channels 45, 46 and' the core and the bands may be preheated. In order to neutralize stresses induced in the material due to the compression moulding, the bands are given a shear stress by rotating the core 28 by means of a hydraulic motor 50 which drives a pinion 51 engaging teeth 32 on a flange 31 of the cores. The Specification gives details of the magnitude of the shear stresses employed. The mould halves are then opened, and by making the core surface of, e.g. polished chromium plate, so that its adhesion to the rubber is relatively small the bands remain in the mould halves. To provide the necessary friction between the core and the bands to produce the shear stress, the core may have slight ridges on its surfaces. A shaped tyre carcass 55, Fig. 6 containing a curing bag 56 is then inserted in the mould and the mould halves closed to within #in. of each other, the bag 56 is then inflated through an opening 57 to expel the air from between the moulds. The mould halves are then closed and the tyre and tread moulded under heat and pressure. The mould halves are then opened and the tyre assembly and curing bag placed between mould halves 60. 61, Fig. 8. having a tread pattern forming design 63. The mould halves 60, 61 have a slightly bigger mould cavity than the previous mould halves. The tyre assembly is then moulded under heat and pressure to form the finished tyre. Alternatively the tyre assembly may be vulcanized in a vulcanizer of the McNeill or Demattia type. The mould surfaces may be of matte surfaced chromium or nickel plated. Specifications 703,973 and 709,387 are referred to.

Title: Improvements in and relating to apparatus for Positioning Covers on Substrates
IPC: H05K13/00
Filed: 1967-02-22
Abstract: 1,168,353. Making microminiaturized electronic components; stamping. INTERNATIONAL BUSINESS MACHINES CORP. 22 Feb., 1967 [24 Feb., 1966], No. 8335/67. Headings B3A and B3Q. Apparatus for positioning a cover on a substrate comprises means for conveying substrates to a first station, an inclined shoot for supplying covers successively to the first station, means disposed to exert a downward force on covers emanating from the shoot, and guide means positioned initially to abut and subsequently slidably to support a leading edge portion of a cover emanating from the shoot. Substrates 12 of microminiature electronic modules are fed by carriers 20 which are engaged by a belt 32 to a capping station 26. Covers 18 are fed down a shoot 40 to pass under a pressure pad 43 on to the surface 48 of a guide rail 46. A current of air flowing through a perforated plate 49 pro. vides a gentle downward force on the substrates 12 to maintain them in position without physical contact and without disturbing a tacky layer of encapsulating material 16. As the carrier 20 moves forwardly the leading edge of the module contacts the inside edge of the cover which is then drawn out from the shoot. A spring 45 on the pad 43 snaps the cover in posi. tion on the substrate. A malfunction device 60 comprises a pivoted arm which contacts unseated covers only and which co-operates with a photo-cell to stop the conveyer by means of an associated switch when such a cover is detected. To detect a missing cover a photo-cell 64 is provided on one side of the conveyer with a light source on the other, a missing cover allowing light to illuminate the cell. The modules are then conveyed to a crimping station 31, where a locator punch 70 is cammed downwardly and a lower punch is then moved upwardly by a cam 80. The punches 70, 71 are then cammed upwardly to position the module between crimping punches 72. A cam 73 is moved downwardly to move levers 75 outwardly thereby forcing the punches inwardly to crimp the cover 18 into engagement with the substrate 12. The substrate may comprise any suitable element to be assembled with a cover, including filled portions of medical capsules.

Abstract: 421,508. Air-compressors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. March 16, 1934, No. 8347. Convention date, March 17, 1933. [Class 8 (i)] An air-compressor of the kind having a rotary cylinder and double acting piston and wherein a passage connects the ends of the cylinder which when open unloads the compressor is provided with means such as an oil pump actuated by the compressor for forcing lubricant into the connecting passage to seal it and load the pump. In a refrigerator the compressor comprises a fixed body 25 with cylindrical bore within which is mounted a rotary core 27 driven by the shaft 27a of the electric motor. The rotary member is provided with a transverse cylinder 29 in which is fitted the pump piston 30, the ends of which are curved to conform to the sides of the bore of the cylinder walls. The piston is connected by means of a transverse slot 33 therein engaging a lug 32 on a shaft 31 not in line with that of the driving shaft 27a, whereby reciprocation of the piston relative to the cylinder is effected. The compressor has an intake port 34 in the form of a groove which communicates through a passage 36 and check valve with the intake coil of the refrigerator. The intake 34 and delivery 38 are covered and uncovered at the appro. priate times by the piston. The ends of the cylinder 29 are connected by a longitudinal groove 55 which is intersected by a circum. ferential groove 49 forming part of the circuit of the lubricating pump. When starting up the groove is free and the compressor is unloaded, but on attaining a given speed the oil pressure rises sufficiently to form a seal which checks the communication and the compressor becomes loaded. The pump is constituted by a vane 45 at the bottom of the shaft 31 moving in a cylinder 44 at the bottom of the body 25. The pump is immersed in the oil sump and delivers through a channel 47 in the shaft 31 to the groove 49 and thence to the other parts to be lubricated.

Title: Improvements in and relating to vehicle clutches
IPC: B26B21/18
Filed: 1932-03-21
Abstract: 381,094. Clutches for vehicles. VOITH, W., VOITH, H., and VOITH, H., (trading as VOITH, J. M.), Heidenheim, Wurtemburg, Germany. March 21, 1932, No. 8416. Convention date, March 20, 1931. [Class 80 (ii).] Clutches for vehicles are of combined friction clutch and hydraulic flow clutch type in which the shut-off valve for the fluid clutch is integral with the movable friction clutch member, so that when the friction clutch is disengaged the fluid clutch device can be gradually shut off and as the friction clutch is moved to position for engagement the fluid clutch gradually takes up the drive and at the same time supplies fluid pressure to maintain friction clutch engagement. The actual engagement of the friction clutch is controlled and its disengagement effected by manual control of an auxiliary valve in a forced supply of fluid to the space between the friction clutch elements. A fluidclutch blade-wheel 3 of the F÷ttinger type is secured to the driving-flywheel 2, the driven blade wheel 4 being secured to the driven shaft 6. The shut-off valve 5 of the clutch is integral with the friction-clutch member 18 splined to the shaft 6 and controlled by the main clutch pedal, the co-operating clutch member 19 being secured to the flywheel 2. Fluid is pumped to nozzles 16, 17 supplying respectively the fluid clutch and the space between the clutch members, the latter having escape-orifices 22. A spring 11 tends to close the clutch 18, 19, but its strength is insufficient to produce engagement while fluid is pumped to the interclutch space. Similarly, the pedal cannot disengage the clutch against the pressure produced by the fluid clutch until fluid is supplied through the auxiliary valve to the interclutch space. With the friction clutch closed and the fluid clutch operating, the pedal is lowered for declutching and in its first movement opens the auxiliary valve, which supplies pressure to the interclutch space to enable the friction clutch to be opened and the valve 8 to be closed to stop the drive. On release of the clutch pedal, the spring 11 returns the clutch member 18 to proximity to the member 19, at the same time gradually bringing the fluid clutch into driving condition. Near the end of the pedal movement, the auxiliary clutch is closed and fluid escapes through the orifices 12, so that the friction clutch is closed by the action of the spring and the fluid-clutch pressure.

A socket contact especially for a valve-holder is formed from a beryllium copper blank of rectangular shape, by cutting a longitudinal slot therein and bending the blank back upon itself to form a pair of V- or U-shapedlegs 1, 2, interconnected by bridge-pieces 3, 4, constituted by the ends of the blank. The space between the apices of the legs 1, 2 forms the socket mouth, the contact-pin engaging surfaces comprising a pair of tongues 5, 6 projecting respectively from the legs 2, 1, each tongue extending towards that leg to which it is not attached. Hence on insertion of a contact-pin the tongues 5, 6 are forced apart and exert a twisting movement on the legs 1, 2. The bridge-pieces 3, 4 are bent into a V to provide an opening into which the contact-pin may pass after being inserted into the socket mouth. An extension 7 on one end of the blank serves as a terminal tag. In a modification, Figs. 3, 4 (not shown), suitable for a larger size contact-pin, the bridge-pieces are bent into arcuate shape and the tongues 5, 6 are bent to define a square-shaped opening. A valve-holder, Figs. 5-7 (not shown), comprises seven socket-receiving apertures, circularly arranged, six apertures being intended to receive the socket of Figs. 1, 2, and one aperture the socket of Figs. 3, 4. The sockets are inserted by pressing together the lower parts of the legs 1, 2, the legs then automatically springing outwardly in the apertures which are shaped so that the sockets are retained and held against rotational movement.
