Title: Improvements in rotating cylinder engines
IPC: F02B75/26
Filed: 1927-05-02
Abstract: 292,738. Wright, A. H. May 2, 1927. Two-stroke-cycle engines; driving-gear.-In a rotating cylinder engine the pistons 11 reciprocate in a cylinder 10 which reciprocates in cylinders 9, the three bodies rotating in a fixed casing 15, 16. The pistons are rigidly connected by a bar 12 on which is formed a bearing for a journal 36 carried bv a rod 35; the reciprocating cylinder has a bearing 10<a> for a similar journal on the rod. The rod forms part of a swash-plate gear; its ends are received by a ring 32 carrying the inner member 32a of a ball-race, the outer member 34 being carried by the centre part 16 of the fixed casing. The bearings reciprocate in slots in the cylinders 9 and 10 and constrain the three bodies to rotate with the swash-plate, the piston and cylinder 10 reciprocating in opposite directions; the cylinders 9 &c. revolve in shafts 14 attached to the cylinder heads. Mixture is drawn from a carburettor 23 into an annular chamber 16<a>; it passes thence through passages 22 formed on the cylinders 9 to inlet ports controlled by automatic valves 20. The interiors of the cylinders 9 with the cylinders 10 form precompression pumps, the mixture being delivered to the combustion chamber in the cylinders 10 through valves 28. Terminal exhaust ports 26 in the cylinders 10 register with ports 24, Fig. 5, in the cylinders 9 at the end of the power stroke, the exhaust passing to a spiral outlet passage 25 formed in the fixed casing. The sparking-plugs are mounted in the pistons. Cylinders, cooling.-Spiral ribs 30 on the cylinders circulate air through the casing, the air entering through the channel 25 after the exhaust has ceased. Pumps.-Vanes 19 formed on the cylinders 9 near the entrance to the passages 22 assist in forcing the mixture into the. cylinders, and blades 31, Fig. 5, help to withdraw the exhaust from the cylinders.

Abstract: 1, 046, 983. Automatic speed control. SEQUENTIAL ELECTRONIC SYSTEMS, Inc. March 19, 1965 [March 23, 1964], No.11716/65. Heading G3R. To provide retroactive speed control of a rotary element down to zero speed a speed and angular position signal is used to effectively amplitude modulate a carrier frequency, and one of the sidebands only is compared with a reference signal in a phase comparator that produces a signal which, upon amplification, drives the rotary element. The arrangement is such that the element follows the reference (which may be produced by a second rotary element) exactly in r.p.m., with a phase displacement sufficient to produce the required power. In Fig. 1 (not shown) an unspecified optical device 12 produces sine and cosine signals of the angular position of an electric motor shaft 13, to facilitate side band selection in a transistor modulator 16 (which is described, Fig. 2, not shown). In alternative arrangements modulation is effected in the optical device, either by energizing the lamp at carrier frequency, or by rotating a grating at a speed corresponding to carrier frequency.

Abstract: 376,855. Control of D.C. motors. BRITISH-THOMSON HOUSTON CO., Ltd., Crown House, Aldwych, London, and CANSDALE, J. H., 40, Murray Road, Rugby. April 24, 1931, No. 12172. [Class 38 (iii).] The transfer from regenerative to rheostatic braking of a tramway &c. motor E is effected by a contactor which opens contacts 16c to interrupt the normal circuit for the shunt field H and closes contacts 16 to connect the shunt field across the supply or in a modification, Fig. 3 (not shown), direct across the motor armature. During motoring and regeneration control is effected by the controller C. In the first position of the controller C, coils 1a, 1xa are energized to close line contactors 1, 1x, an interlock 1g also closing so as to allow further movement of the controller to exclude armature resistance B by energizing coils 2a .. 5a of contactors 2 .. 5 and thereafter to include field resistance J by de-energizing coils 6a .. 12a of contactors 6 .. 12. Depression of the rheostatic braking pedal K, by opening contacts 14 ensures opening of line contactors 1, 1x and if controller C has been returned to its "off" position energizes (1) coil 15a over interlock 1b, which closes when line contactors open, to close contactor 15 and so complete a braking circuit through resistance L, (2) coil 16a over interlock 12x, which closes when contactor 12 opens, and so operates the transfer contactor 16, and (3) coils 6a .. 11a and so excludes sections of the field resistance J. Further depression of the controller K causes energization of coils 2a .. 5a and exclusion of armature resistance B. Overvoltage during braking causes sufficient energization of coil 19a to open the circuit of field contactor coils 9a &c. at the point 19.

Filed: 1925-05-11
Abstract: 254,057. O'Connell, J., and K.err, H. H. May 11, 1925. Butter. - A rotary churn, more particularly intended for treating cream in the manufacture of butter comprises a horizontally arranged barrel 1 having an opening 3 in one end 14 which is supported by peripherally disposed bearings so that free access may be had to the inside of the barrel during its operation, the other end of the barrel being supported by an axially arranged shaft rotating in a fixed bearing. The end 14 is flanged at 13 to run on rollers 12 carried by rockers 5, Fig. 8, on shafts 6 on tne two sides of the barrel. Workers 59 within the barrel are operatively connected to an annular rack which is mounted on the axially arranged shaft and fitted with band-brake control; they may thus remain stationary or be caused to turn relatively to the barrel. Change-speed gearing is interposed between the driving-shaft and the barrel so that the barrel may be driven rapidly or slowly as desired. The driving-shaft 24 carries a fixed pulley 30, a loose pulley 31, and a pulley 32 upon a loose sleeve 33 carrying a pinion 34. and the belt 81 is shifted by fingers 52 upon a slide 50 which has rack teeth 53 in mesh with a pinion 54 on a shaft 55 provided with a hand-wheel 58. When the belt is on the pulley 30 a direct drive is imparted by a bevel-wheel 23 on the shaft 24 and the barrel is driven rapidly through the gearing 22, 19, 18, Fig. 4; if, in these circumstances, a brake band 71 has been tightened upon the flange 70 of an internally and externally toothed ring 67 in gear with pinions 66 on the shafts 61 of the workers, these workers are not turned. For slower movement of the barrel the belt 81 is shifted on to the pulley 32, and as this is being effected a projection 49, Fig. 6, on the slide 50 passes over the bend in a lever 46 so that under the influence of a weight 47 levers 45. 43 are actuated to slide along a clutch part 42, keyed to the shaft 24, into engagement with a clutch part 41 on a freely mounted pinion 40. The drive is then imparted to the shaft 24 and bevel-wheel 23 through the gearing 34, 35, 39, 40. In operation, the barrel is first rapidly rotated, and then as the butter is being formed the speed is reduced, and finally the workers are put into action by application of the brake 71 by the use of a hand-lever 78.
