Title: Improvements in or relating to carburetors
IPC: F02D9/00
Filed: 1930-06-13
Abstract: 363,339. Valve components. WEYMANN, C. T., 18, Rue Troyon, Paris. June 13, 1930, No. 18194. Convention date, June 14, 1929. Void [Published under Sect. 91 of the Acts]. [Class 135.] Closure members.-The pressure existing at the spraying nozzle 7 of a carburetter is maintained substantially constant throughout all engine speeds by varying the air passage at the nozzle in accordance with the engine suction. The air passage is produced by moving two sliding blocks 5, 6 in opposite directions by means of a servomotor under the control of the suction existing at the nozzle. The outer surfaces of the blocks are curved to fit the mixing tube 1, the inner surfaces being grooved to accommodate, in the closed position of the blocks, the transverse nozzle 7. A tube 8, Fig. 1, transmits the suction at the nozzle to a diaphragm 10 connected through a link 11 to an arm 12 adapted to move between contacts 14, 15. According to the contact in use, a source of electrical energy 13 drives a motor 16 in one direction or the other. This motor is connected through a pinion 17 with a sector 18 pivoted at 20, and connected on opposite sides of its pivot through links 21, 22 with the blocks 5, 6. In a modification, the blocks are moved by the rotation, by the servomotor, of a sleeve 27, Figs. 2 and 4. Each block is provided with a projecting stud 23, 24 adapted to move in slots 25, 26 in the wall of the mixing chamber. Between the sleeve 27 and the wall are bushes 30, 31 pressure on which is exerted by springs 32, 33, which bear against the heads of the studs. Around the nozzle 7, Fig. 4, is an annular passage 45 through which, and a tube 8, suction is transmitted to the diaphragm 10. This diaphragm, through mechanism 14 .. 19 and arm 34, is adapted to rotate the sleeve 27 which is provided with helical slots 28, 29 through which pass the studs 23, 24. Rotation of the sleeve therefore produces axial movements of the blocks, and variation of the passage around the nozzle.

Title: Brake system
IPC: F16D65/22
Filed: 1964-05-05
Abstract: 1,059,484. Hydraulic brakes; vehicle brakes. ROCKWELL-STANDARD CORPORATION. May 5, 1964 [July 3, 1963], No. 18566/64. Headings F2E and F2F. A master cylinder 11 in a vehicle hydraulic braking system of the kind wherein pressure applied in a primary hydraulic circuit applies the brakes on one or more wheels and the drag forces on said brakes generate pressure in a secondary hydraulic circuit to apply brakes on other wheels, comprises a reservoir 266, a single piston movable in a bore of the master cylinder between brake applied and brake re-  leased position defining a first pressure chamber 176 having first and second ports 13 and 194 connected to said primary circuit and reservoir respectively, and defining a second chamber 196 having third and fourth ports 192 and 258 connected to said reservoir and secondary circuit respectively, and a check valve 278 for selectively opening and closing said fourth port, which valve is engaged by said piston in the brake released position to hold it in the open position. On movement of the piston to the left to apply the brakes, port 194 is immediately closed by a cap 190 of the piston to isolate the primary circuit. Simultaneously, valve 278 is closed by a spring 274 to isolate the secondary circuit. After the pressure in the primary circuit has built up to sufficiently apply the brakes associated therewith, the pressure in the secondary circuit is increased by the torque reaction of said brakes. This pressure additionally acts on a flange 276 of the check valve to maintain it closed. As  illustrated in Figs. 1-7 (not shown), the braking system apart from the master cylinder is as described in Specification 1,014,963. The primary circuit operates the front brakes of the vehicle, the torque reaction of said brakes pressurizing the secondary circuit to operate the rear brakes. The Specification also states that the torque reaction of the rear brakes may be used to actuate the brakes of a trailer vehicle in a similar manner. The check valve isolating the secondary circuit when the piston of the master cylinder is moved from the brake released position, permits the secondary circuit to be maintained filled from reservoir when adjustment for shoe wear is made, and allows excess fluid to flow back to the reservoir. In the embodiment of Fig. 5 (not shown) the primary brake actuator (91) may enclose a wedge/roller mechanism as disclosed in Specification 862,439.

Title: Blow-moulding machines
IPC: B29C49/28
Filed: 1975-05-03
Abstract: 1507551 Blow moulding ILLINOIS TOOL WORKS Inc 3 May 1975 18618/75 Heading B5A A continuously operating blow moulding machine for tapered preforms comprises a carriage 10 intermittently rotated about a horizontal axis and carrying at equally spaced intervals a series of heated mandrels 25 tapered to match the preforms, a preform loading means 11 supporting a horizontally disposed stack of preforms and arranged to feed them in turn on to a mandrel projecting horizontally from the carriage 10 by means which grip the rim of the leading preform, a split blow-mould 12 mounted to close about a mandrel 25 projecting vertically downwardly from the carriage, and take-off means 13 for reciprocating along a downwardly inclined mandrel to grip a blown article and withdraw it from the mandrel. Two carriages 10 (one behind the one shown in Fig. 1) are rotated on the same shaft and each is fed from a separate stack, Fig. 8, by the same loading device 105 carrying fingers 120 which engage behind the rims of the leading preforms. The device 105 is moved forward by a ram 108 to load preforms on to the mandrels. The rest of the stack is urged forward by continuously running belts 130 on which they rest, but other fingers 110, 111 (Figs. 6, 7, not shown) hold them back. The blown articles are discharged down suction tubes 156, Fig. 9, after fingers 161 are forwarded by a ram 142, cammed into engagement with the articles by surfaces 162a, and retracted to the dotted line position. The preforms are held on the mandrels 25 by suction applied through passages 224 to 228, Fig. 10. The tapered portion 204 of the mandrel is heated by cartridge heater 210 and neck portion 208 is insulated from this by sleeve 216. Thus as the preform body expands the neck portion does not expand and can slide up the cool portion 208. Also an initial gap 205 at the step assists in preventing the end of the preform losing contact with the mandrel during expansion. The blow moulds, Fig. 3, are cooled through passages 88 and have a bottom plunger which is spring biased downwardly to disengage the blown article on mould opening. A pair of moulds is opened and closed by raising and lowering a shaft 50 connected to one half of each mould by arms 66. The pivoted mould mounts 67, 70 of opposite halves of different moulds are connected by links 71, 72 so that the two halves of each mould operate in synchronism.

Abstract: 595,887. Spring upholstery. HODGES, F. G. July 20, 1945, No. 18666. [Class 52(iv)] Spring assemblies comprising upholstery springs 31 secured together in succession and also to upper and lower sheets 151, 150 of sisal or other material by staples 201, 202, Fig. 14, are produced automatically by a machine having a transverse battery of pairs of feeding-chains 41, 42, Fig. 4, which receive gravity-fed springs from hoppers 30. Pegs 60 on the chains convey the springs to troughs with resilient sides 95 and transversely reciprocating end plates 101 which push the springs against similar plates 105, Fig. 6, and a retractable rotary stop 136 then turns the spring to bring the end knot into a predetermined position in which it will not obstruct the stapling operation. A vertically reciprocating frame 16, 17 18, Fig. 1 actuated by a connecting rod 23 has pairs of dependent plates 91, 92, Fig. 4, mounted thereon which carry each spring downwardly and inserts it between the fabric sheets 150, 151 and in contact with the preceding spring. Claws 161, 162 descend and feed the fabric downwardly until the spring arrives at the stapling position, Fig. 9, and cam-operated stapling-heads 167 then insert staples through the sheets and around the abutting end turns of the springs, the plates 91, 92 serving as stapling anvils. In this position arms 157, 158 open the claws and the cycle of operations is repeated. The feeding chains 41, 42 are ratchet-operated by a rack 46 on the upstroke only of the reciprocating frame and by omitting feed pegs 60 a gap is left between a desired sequence of springs to facilitate severance into squabs by a blade 207 at the outlet. The main drive is continuous, the pulley 27 being geared to the wheel 22 actuating the connecting rod 23. Separate motors drive the transversely moving plate 101 and the spring-turning device 136 and timing is effected by lugs on the moving parts which operate limit switches to start, stop and reverse the motors. The stapling devices are continuously driven by separate motors 172, 173 and a single cycle operation is performed when clutches 180, 181 are actuated by trip levers 190 and projections 182, Fig. 1, on the vertically reciprocating frame.
