IPC: F28G3/16
Abstract: 533,609. Soot blowers. BABCOCK & WILCOX, Ltd., and WEEKS, E. G. Oct. 25, 1939, No. 28675. [Class 99 (ii)] In a soot-blower of the kind in which a valve 24 controlling the admission of cleaning-fluid to the blower tube 3 is connected to a piston 22, the pressure above which may be released by opening a pilot valve 49, whereupon the pressure of the cleaning-fluid beneath the piston causes the piston and valve 24 to be raised, means are provided for cushioning the movement of the piston by preventing or limiting the escape of fluid from above the piston during the latter part of the opening movement of the valve 24. In the form shown, a tapered plug 37 on the piston enters the aperture 35 through which the fluid escapes. The blower may be constructed as described in Specification 532,692.

Patent GB-547822-A (GB)
Abstract: 547,822. Miners' electric lamps. PORTABLE LAMP EQUIPMENT CO., Inc. March 10, 1941, No. 3267. Convention date, March 9, 1940. [Class 39 (ii)] [Also in Group XXXVI] A two-filament miner's head-lamp consists of a moulded casing 20 hinged to the clip 26 by which it is secured to the helmet, so that the beam may be angularly-adjusted, and provided with a bayonet socket connection 55 to receive the usual plug connector from the battery ; when the plug is inserted into the T-shaped bayonet slot the contacts 96 carried by a sleeve in the plug come into engagement with an insulating part of a fixed contact-carrying member 65 in the socket. Not until the plug has been rotated with the pin 84 engaging one or other of the horizontal parts of the T-slot (according to which of the two filaments is to be bought into use) is contact effected. This arises because in making the mechanical joint a triangular recess in a sleeve 70 on the fixed member 65 is engaged by a correspondingly-shaped pin 99 on a rotatable contact-member in the plug and  rotation of the plug causes relative rotation between this member and its counter contacts removing the contacts 100 from the insulated recesses 103 on to its contact parts. At the same time, the rotation swings the contacts 96 on to one or other of the contacts 68 on the member 65 connected with the contacts 69 with which the terminals of the two-filament lamp socket are in engagement. Thus the electrical circuit is broken at two places in the act of disconnecting the plug before it can be detached from the socket. The lamp is carried in a bayonet holder in a spring arm 50 held in the casing ; it bears against the front glass cover .of the casing so that if either lamp or glass cover should break the circuit is broken by the spring- arm which is thus released to lift the lamp away from its fixed contacts 69. The plug connection from the, battery enables the battery to be connected up to a charging circuit in which sockets similar to those described are used.

Abstract: 1378765 Draw-twisting machines MASCHINENFABRIK RIETER AG 1 Dec 1971 [1 Dec 1970] 55688/71 Heading D1D In a draw-twisting machine waste filament is fed through a traveller, sliding on a fixed ring, and onto a rotating waste spool, and is traversed along the spool by an upwardly inclined guide.

Title: Injection method for engines operating with controlled ignition, and apparatus for carrying out the said method
IPC: F02D41/30
Filed: 1967-12-12
Abstract: 1,213,290. Fuel injection engines; valve gear. SOC. DES PROCEDES MODERNES D'INJECTION SOPROMI. Dec. 12, 1967 [Dec. 19, 1966], No. 56446/67. Heading F1B. [Also in Division G1] A fuel injection system for an I. C. engine is electronically controlled so that in addition to the main fuel charge an auxiliary constant fuel charge is delivered into the combustion cylinder near the ignition point immediately prior to the ignition spark formation so that even weak mixtures are ignited by the spark. Synchronization between the main injections and rotation of the camshaft is obtained by a pulse generator Fig. 3 comprising a magnetic sector 38, mounted on the camshaft, which passes through a gap 37 in a core 33 once per revolution. Three windings 34-36 are wound on the core, the first being energized with D. C. Thus a positive and negative pulse is produced in each winding as the sector 38 passes through the core gap. Four such pulse generators are used with a four cylinder engine to control four fuel injectors with control windings 112-115, Fig. 4 supplying both the main and auxiliary fuel charges. Thus the first pulse generator (101), Fig. 7 (not shown) produces positive pulses at 16, 19 which fire thyristors 117,137 to energize injection winding 113 to supply the main fuel charge to its cylinder. The third pulse from generator 101 is fed to a timing circuit Fig. 8 comprising uni-junction transistor 107 whose output circuit through transformer 108 is closed at 8, 10 by relay 110 energized by the current through winding 113. After a preset delay, transistor 107 produces a pulse at 12 which fires thyristor 123, to quench thyristor 137, charge capacitor 124 and quenchthyristor 117, thereby stopping the main fuel injection via winding 113. The next pulse generator (103) fires thyristors 121, 119 to energize injection winding 115, a similar sequence of events being followed, with the charge on capacitor 124 acting to augment the initial current through the injection winding to produce rapid opening of the injection valve. Similar circuitry produces energization of the injection windings for the auxiliary fuel charges. Synchronizing pulses 25 are derived from a relay energized by the current through the primary of the induction transformer (190), Fig. 6 (not shown) of the I.C. engine. Thus, where injection winding 115 is supplying a main fuel charge it energizes relays 315, 361 which become self-holding, and closes contacts 261. When a synchronizing pulse 25 arrives, it fires thyristor 127 and energizes injection winding 112. Thyristor 127 also shortcircuits relay 315, and when pulse 25 is finished, thyristor 127 and injection winding 112 return to normal.

Abstract: 1367525 Variable-speed friction gear GKN TRANSMISSIONS Ltd 1 Dec 1972 [8 Dec 1971] 56892/71 Heading F2D A steplessly variable friction drive comprises a first torus disc 28 driven by an input shaft 13, adjustably inclined first rollers 43 between the disc 28 and a second torus disc 41, and a combined thrust bearing and differential mechanism comprising raceways 75, 74 connected respectively to the first and second torus discs, second rollers 73 between the raceways and rotatable on bearings whose axes lie on an imaginary conical surface whose axis is the rotary axis of the discs, and a carrier 72 for the second rollers transmitting drive to the output shaft 14. Each reaceway 74, 75 is a surface of revolution generated by a straight line or a circular arc about the rotary axis of the discs, and the second rollers are correspondingly conical or, as shown, barrel shaped. In the transmission shown a Belleville washer 31 and oil pressure supplied by a pump 35 to a cylinder 34 apply axial thrust to the first disc, and the reaction is taken through the rollers 43, second disc 41, rollers 73 and race member 76, by an abutment 76a on the input shaft. The inclination of the axes of the first rollers 43 is adjusted, e.g. manually and/or automatically in dependence on power or torque of a prime mover coupled to the transmission, by a mechanism comprising a series of three-armed levers 49 which are turned about pivotal mountings 68 by angular adjustment of a sleeve 55 which has an operative connection 59, 62 with a hydraulic jack. The rollers 73 are carried by needle bearing 79 lubricated by oil flung from the shaft 13 and directed by catchers 81 into bores 80. The drive from the carrier 72 to a member 69 on the output shaft is transmitted through teeth 70, 71. A member 97 is engageable with teeth 96 to serve as a parking brake. Since the output shaft rotates in the opposite direction to the input shaft, it may be desirable for automative use to incorporate drive reversing means. This may be done by providing a step-up and reversing gear at the input side, or a planetary friction gear between the member 69 and the output shaft.
