Title: Variable ratio power transmission system
Inventor: LAMBURN ALAN SALISBURY
IPC: B60K17/08
Filed: 1964-03-25
Abstract: 1,100,333. Change-speed gears. AXEL WICKMAN TRANSMISSIONS Ltd. 25 March, 1965 [25 March, 1964], No. 12520/64. Heading F2D. [Also in Division B7] In a power transmission system for a motor vehicle, a main change-speed gear 24 and an auxiliary two-speed planetary overdrive or underdrive gear 40 lie on opposite sides of a transfer gear whose output gear 35 is coaxial with, and drives, oppositely extending output shafts 33 parallel to the output shaft 27 of the main gear 24, which shaft 27 extends coaxially through the input pinion 36 of the transfer gear to drive an input planet carrier 39 of the auxiliary gear, an output ring gear 43 of which drives the pinion 36. Two arrangements are described. In the first, Fig. 1, a transverse engine 10 drives the main change-speed gear 24 through a frictionclutch 14 and a gear train 32. The transfer gear 35 drives half-axle road wheel shafts 33 through a bevel differential 34. The second arrangement, Figs. 3 and 4 (not shown), has a longitudinal engine in front of the clutch and main gear, and the transfer gear pinion (36) drives, through a two-speed parallel shaft gear, aligned shafts (75, 76) driving respectively the rear and front axles of a four-wheel drive vehicle. The rear axle drive shaft (75) is directly driven and carries a transmission brake (91), whilst the front axle drive shaft (76) is driven through a lockable one-way clutch. The two-speed gear (92) has a wheel (82) splined on an output shaft (80) and slidable to mesh a wheel (78) on the input shaft for low or to clutch an intermediate wheel (79) on the output shaft for high. The auxiliary planetary overdrive gear 40 is controlled by a conical clutch/brake member 49, moved axially by hydraulic pressure, supplied by a pump 61 driven by the input shaft 38 of the gear 40, acting through a spring-opposed piston and a thrust race 57, to clutch the sun gear 42 and the ring gear 43 together for direct drive, or to hold the sun gear 42 for overdrive. The ring gear 43 is splined to a sleeve 45 carrying the pinion 36 and a speedometer drive 65. A one-way clutch 55 between the shaft 38 and the ring gear 43 unloads the clutch 53/54 once direct drive is established. The auxiliary gear 40 (Fig. 1) or (94) (Fig. 3) may form an optional replacement for a power take-off shaft driven from the shaft 27. The disclosure of Figs. 1 and 2 is also the subject of Specification 1,100,334.

Filed: 1917-09-10
Abstract: 166,174. Sch÷nberg, W. Sept. 10, 1917. Web feeding and cutting arrangements.-In machines having the paper-carriage provided with web-feeding devices operated by a hand-lever, a transversely movable cutter for the web is operated by a reverse movement of the hand-lever. A frame 1, secured to the paper-carriage, supports a delivery-roller 8, a feed-roller 10, and the feeding and cutting-devices. The feed-roller is provided with a pinion 16 gearing with a pinion 17 which carries a pawl 24 engaging a ratchetwheel 22. The hand-lever 23 engages a lug 29 on an arm 21 secured to the ratchet-wheel. On depressing the hand-lever the web is fed, the movement being limited by an adjustable stop 30 in the path of the hand-lever. A serrated cutter-wheel 72, Fig. 5, is mounted in a carriage 64, described below, which is drawn to the right or left by a cord 57 wrapped at one end on a drum 40 and at the other end on a spring-drum. The shaft 39 of the drum 40 is provided with a pinion 38 gearing with a rack 34 secured to a plate 33 which is guided on a pillar 35. The hand-lever is formed with an arm 31 carrying a roller 32 engaging the plate 33, and on rocking the hand-lever to the rear the plate is depressed and causes the drum 40 to pull the carriage 64 to the left, the spring-drum returning the carriage when the hand-lever is released. The car riage consists of a slide 65 mounted on a bar 61 and provided with a pivoted frame 68 carrying a shaft 73 to which are secured the cutter-wheel 72 and rollers 76. The frame also carries pivoted arms 70 provided with rollers 71. The cutterwheel projects into the space between tracks 48 for the rollers, springs 78, 81 pressing the rollers against the tracks. The rollers engage the web at points adjacent to the cut and thus render unnecessary a counter-cutter. Only one roller 76 may be employed, and the pivoted frame 68 may be replaced by a yielding bearing for the shaft 73. To permit of lateral adjustment of the cutterwheel, the rail 61 and the tracks 48 are secured at the ends to laterally adjustable brackets 45, which are secured by bolts passing through slots in ledges 50. The rail 61 is vertically adjustable in slots 63 in the brackets 45 and is secured by screws 62.

Filed: 1942-09-15
Abstract: 559,026. Cracking oils. ARNOLD, J. C. (Standard Oil Development Co.). Sept. 15, 1942, No. 13016. [Class 32] Heavy hydrocarbon oils, e.g. the residum produced by distilling off the fractions boiling up to 850‹F from a crude oil, are reduced in viscosity to produce a gas oil by spraying the heated oil, at least partly in the liquid phase, into a chamber into contact with a solid granular material, e.g. hydrocarbon coke, pumice, silica, alumina, " Super filtrol," previously heated to 900-1200‹F., conducting converted products to a separating chamber to separate the powdered material from the vapours, then suspending the separated material in an inert gas and passing it to a regenerating chamber where absorbed hydrocarbons are burnt off by admixture with air, the regenerated material being returned to the reaction chamber. Residuum of an East Texas oil heated to 850-950‹ F., together with steam from line 2, is discharged through a manifold 4 into a reactor 5 where it mixes with coke from a pipe 70. The suspension passes through a pipe 8 to a separator 10 from which the vapours pass through line 14 for further treatment. The separated coke falls through a pipe 12 into a chamber 15 where it is mixed with steam, flue gas or carbon dioxide. Heavy particles are withdrawn through line 20 and the suspension passes to a regenerating chamber 24 to which air is supplied by a pipe 23. Combustion of the hydrocarbon material takes place in the chamber 24 and the suspension passes to a cyclone separator 40 from which the coke particles are fed through a pipe 45 to a dispersion chamber 60 for return to the reactor 5. Specifications 525,443, 538,383, [Group XXXVI], 542,989, and 544,366 are referred to.

IPC: F02B25/00
Abstract: 131,592. Buchi, A. Aug. 17, 1918, [Convention date]. Valves. - In a twostroke-cycle engine, combustion products are withdrawn and a fresh charge induced by the ejector action of gases exhausted from the cylinder before the completion of the expansion stroke. According to the construction shown in Fig. 2, terminal inlet and exhaust ports are provided at c, d respectively, the combustion products being withdrawn by the ejector action of gases escaping through a nozzle i. The gases discharged through the nozzle i are supplied to a reservoir h through a valve g which is opened mechanically during the expansion stroke and closed before the piston uncovers the exhaust port. A modified construction is described in which, in a multicylinder engine, combustion gases are discharged into the storage reservoir through ports uncovered by the piston and controlled by a longitudinally-adjustable rotary cylindrical valve. In an engine having oppositelymoving pistons, the ports leading to the storage reservoir are controlled by a flat slide valve.

Abstract: 555,255. Soldering aluminium. MASCHINENFABRIK OERLIKON, and BOLLER, W. Sept. 18, 1942, No. 13207. [Class 83 (iv)] Parts of aluminium are soldered together by first soldering to each part a coating of a metal or alloy different from the solder and subsequently soldering the two coatings together. Copper coatings may first be soldered to the aluminium parts by tin solder and the coatings then united by tin soldering. The copper coatings may be tinned during the first operation and the parts stored in this form. Parts such as aluminium coil ends may thus be provided with soldered metal coatings before assembly in an electrical machine and the ends soldered together after mounting in the machine. The soldered coatings may be in the form of perforated or other foils or in the form of wires or bands wrapped round the parts. In another form the aluminium parts after removing the superficial layer of oxide may be coated with a solder and the coating applied in powder form while the solder is still liquid. Tin or cadmium solders may be used. The coatings before application to the aluminium parts may be coated With solder in a fused bath.
