Title: Improvements in or relating to the manufacture of hollow rubber articles
IPC: B29C65/74
Filed: 1925-04-08
Abstract: 233,676. Roberts, F. T. May 12, 1924, [Convention date]. Moulding hollow rubber &c. articles. - Comprises a method of making hollow articles of plastic material wherein a plurality of marginal seams are simultaneously formed between different pairs of layers. The invention is illustrated in connection with a toy elephant which is formed from four layers of rubber, the first and fourth layers being united marginally to form the body, and the first and second and third and fourth being respectively united to form the legs. An upper, fixed platen 10 carries a cutting frame 20 of suitable outline and co-operates with a lower, hydraulically-actuated platen 11. Layers of rubber are fed between the platens from rolls adjacent the press, and comprise an upper layer 45, an intermediate folded layer 43 extending just beyond the region of the legs as indicated at 46, Fig. 5, and a bottom layer 42. The edges of the cutter 20 are bevelled at 23 to press the marginal portions of the severed article together and form seams. To prevent adhesion except when under pressure, the rubber layers are treated with starch, soapstone, &c., and the two portions of the folded layer 43 are separated by a sheet 44 of paper, or the contacting faces may be vulcanized to prevent adherence. The layer 42 is associated with a layer of paper 41 which lies on the platen 11 and ensures cutting of the layer 42. After the severing operation, the platen 11 is lowered, fresh stock is drawn from the rolls and the severed biscuit is removed and vulcanized after first removing the separator 44..The sides of the article are then printed and a suitable inflating-nozzle fitted, e.g. a vulcanized tube B, Fig. 11, having a flattened valve portion b is secured to the trunk by a rubber band b'. Fig. 9 shows the finished toy.
Patent GB-635414-A (GB)
Title: Improvements in or relating to the manufacture of water gas
IPC: C10J1/213
Filed: 1948-04-05
Abstract: 635,414. Gas-producers. HUMPHREYS & GLASGOW, Ltd., and COHEN, H. T. April 5, 1948, No. 9477. [Class 55 (i)] In the manufacture of carburetted water gas, the peak capacity of the plant is raised by admixture with the run gases of stored blow gases which are passed to storage during the blow period whilst the stack valve is open. Part of the blow gases are thus diverted to storage without introducing a backpressure resistance to the flow of air through the generator, as would be the case if the stack valve were closed during a part of the blow period. Preferably the blow gases to be stored are withdrawn before the point of secondary air admission, the maximum pressure being thus available for forcing it through the washer into the storage system. A steam ejector or fan may be used for assisting the flow through the washer. The length of the blow period may be increased to compensate for the loss of heat in the carburetter and superheater due to the withdrawal of unburnt blow gases, or, a part of the blow gas may be burnt and the combustion products released through the stack valve, or tar or oil may be burned in the carburetter, superheater and/or generator top during the blow period. If steam is supplied with the air to the generator, the calorific value of the blow gas is maintained substantially constant by decreasing the supply of steam progressively as the blow proceeds, thus permitting the best use to be made of the air available for secondary combustion. As shown, a valved pipe 7 conveys a part of the blow gases from the top of the generator 1 to the wash box 4, a pipe 4a leading the gases to storage. A steam-ejector 9 assists the flow. The down-run gas pipe 6 connects with a pipe 5 connecting the top of the superheater 3 with the wash box 4, and the pipe 7 may be replaced by a connection, as shown in dotted lines, with the pipe 6, or alternatively, the pipe 7 may branch from the generator-carburetter connection, before the secondary air supply 12, as shown at 7a. Burnt blow gas is discharged through the stack valve 3a, or through a pipe 8 and a waste-heat boiler and a stack valve beyond. The stored heat may be augmented by either or both of the oil tar sprays 10, 10a, the atomization of the oil being effected by steam. In a modification, the blow gases are withdrawn for storage at a point beyond the superheater 3, i.e.. after the gases have been burned to supply air to the carburetter 2 and superheater 3, a steam ejector or other device being provided to effect the withdrawal. The pipe 7, which branches from the valve 3a, or from the off-take 5, is led to a separate wash box 4 and a gas holder designed to offer small resistance to the gas flow.

Filed: 1957-03-22
Abstract: 842,907. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd., SIMMONS, A. W., and WASHBOURN, J. March 7, 1958 [March 22, 1957], No. 9531/57. Class 103 (1). In a fluid-pressure braking system having variable load valves and operatively combined with a vehicle weighing mechanism, a calibrated spring 6 is interposed between one of the vehicle springs 2 and the vehicle under frame 3 and a lever 4 forms a connection between one end of spring 2 and the vehicle underframe 3 and a proportion of the vehicle weight acts down on one end of the lever through trunnions 5 by means of which the lever is mounted on the vehicle underframe 3, this load being balanced by the calibrated spring 6 acting downwards on the other end of the lever together with a control spring 7 of a variable load valve 8 such that the thrust of the calibrated spring 6 is taken by the vehicle frame whilst the thrust of the control spring 7 is against the controlling diaphragm 9 of the variable load valve 8. Thus movement of the calibrated spring 6 due to variations in the load carried by the vehicle, is used to determine the setting of the control spring 7 of the variable load valve 8.

Abstract: 123,469. Ghijsen, H. C., and Naamlooze Vennootschap Vitrite Works. June 11, 1918. Addition to 122,558. Electric lamps.-In making contactplates for lamp-caps, each pair of contactplates in the form of a single blank is fed into a plunger head and the connecting- strip is torn apart, at a weak place at or near its centre, as the contacts are forced down into the mould, the chisel and hammer described in the parent Specification being omitted. A slide 6 pushes the blank from a guide channel 15 into the plunger head 11, in which is a vertical passage of cross-section similar to the shape of the blank. A stationarv cylinder 8 in which the plunger head works has a projection 55 to support the blank as it enters the head, and two plates 54 secured within the plunger guide the corners of the blank. When fully inserted, the blank drops so that the connecting strip enters a groove in a bridge 30 across the passage in the plunger. The bridge has sides curved to correspond with the inner edges of the individual contacts. A fork 25, the prongs of which also correspond in shape to the contacts, supports the plunger by a spring 21 within a tube 51. This tube screws on to the plunger, which is open at opposite sides 10 intermediate its ends. On lowering the fork, the plunger head is carried down until arrested by the mould 16. The fork then descends further, pushes the contact blank on to pointed pins 18 within the mould, and severs them across the bridge 30, the parts of the connecting strip being bent upwards against the sides of the bridge.
