Title: An improved motor train for operating switches
IPC: H01H53/10
Filed: 1928-04-11
Abstract: 292,062. Landis et Gyr Soc. Anon. June 11, 1927, [Convention date]. Electrically -actuated valves.-A gas or water cock is actuated step by step by an electric motor 6 which drives through parallel shafts 8, 9 a casing 16 rotatable on a shaft 10 and connected thereto by a spiral spring. After half a revolution of the casing, an eccentric 18 thereon withdraws a lever 20 from engagement with a port 20' and allows the shaft 10 to snap round half a revolution until the lever engages another port 20". Between the lever and the shaft a strong spring 22 is interposed so as to give a resilient stopping to the motion of the shaft 10. The end 21 of the lever is brought into engagement with the end of a bar 33, which is thus displaced and interrupts the circuit of the motor. A pawl 13 prevents reverse rotation.

Abstract: 1,091,426. Centrifugal separators. OY TAMPELLA A.B. March 11, 1966 [March 12, 1965], No. 10855/66. Heading B2P. In a centrifugal steam separator 6 a film 11 of clean water is formed on the interface between a steam-water mixture and separated steam so that as the steam separates from the mixture, it undergoes thorough cleaning by penetrating the film 11 while crossing the interface. The steam-water mixture is supplied via riser tubes 3 into a collector channel 5 inside a boiler steam drum 1 and is fed tangentially into a number of separators such as 6. The film 11 is formed by spraying clean water into each separator by means of one or more nozzles 8 arranged in the top wall, as shown, or side wall of the separator. Alternatively, the feed water spray is fed through a pipe which passes through the water space of the separator. The clean steam on leaving the separator passes through a coalescer 12 into the steam space and thence via a drier 7 into discharge pipes such as 13. The water leaves the bottom of the separator and enters the water space 2 from which it passes back to the boiler through pipes 4.

Abstract: 215,774. Soc. Veuve Bonnet, A¯nÚ et ses Fils. May 9, 1923, [Convention date]. Shaking and jigging machines; delivery. - Relates to automatic ejection apparatus in machines for moulding concrete &c. blocks, of the type comprising a frame a within which works vertically, by means of a cam b, a piston c terminating in a plate c<1> on which rests a mould d having a movable base e and a cover d<11> provided with a locking device. The ejection apparatus comprises a shaft i, driven by a pulley i<11>, which carries a worm j actuating a worm wheel j<1> mounted on a shaft j<11> capable of engaging a further shaft l through a clutch k, k<1>. The member k<1> is normally held in engagement with the member k by a spring l<1>, while the shaft l is provided at its outer end with a crank-disc o carrying an eccentric pin o<1>, and formed with a cam o<11> on its periphery. The crank o operates a bell-crank lever p" to raise a slide block f, which effects the raising of the base e through rods e<1>, while the cam o<11> produce abrupt rocking of a lever r, r<1>, which is connected by rods s, t to horizontal bars u<1> provided with rollers u<11> mounted thereon. In operation, after compression of the substance in the mould by the cam b, &c. through a pulley h, the driving-belt is transferred to the pulley i<11> and the cover d<11> of the mould is lifted. A lever n is then pushed, which raises a pin m<1> temporarily out of engagement with the clutch member k', which is then pressed by the spring l<1> into engagement with the member k<1>, allowing the shaft l and disc o to rotate once. The block e and the moulded block thereon are thus raised by the block f, and, after a half rotation of the disc o, the cam o<11> causes the bars u<1> to move forward and engage grooves x in the base c below a plate z which carries the moulded block. The block is then pushed on to an adjacent roller-way, after which the bars u<1> are pushed back and another block moulded. Specification 151,991 is referred to.

Title: Improvements in and relating to driving mechanisms of electrically-propelled road or rail vehicles
IPC: B60K1/02
Filed: 1947-04-29
Abstract: 628,051. Electrically-propelled vehicles. HINDMARCH, T., and MENSFORTH, T. April 29, 1947, No. 11478. [Classes 79 (ii) and 79 (iii)] In a road or rail electric vehicle deriving its current from an outside source there are provided one or more pressure fluid operated clutches having a manually controlled slip for acceleration or deceleration of the vehicle. The clutch may directly couple the motor and the rail or road wheel or wheels. The clutch or a number of them may be incorporated in a change speed gear box between the rail or road wheel or wheels. Upon accelerating the vehicle and the slip of the clutch becoming zero the field excitation of the motor may be reduced for further acceleration. With at least two motors they may be connected at will in series or parallel with the supply. The motor or motors may be separately excited. As shown in Fig. 1 the motors a, a<SP>2</SP> supplied from outside source d each drive an axle b<SP>1</SP>, b<SP>2</SP> through clutches f and reduction gearing. In Fig. 2 the motor shaft e carries the driving portion i of the clutch f driving a driven portion m carried on a splined sleeve h, which is rotatably carried on the shaft e. Keyed to the sleeve h is a pinion i meshing with a gear k carried on the driven shaft b<SP>1</SP>. Guards o, n are rotatably mounted on the shaft b<SP>1</SP>. To accelerate the vehicle the motors may be run up using resistors on light load, and then the clutch may be let in at approximately 1/10th of full speed or at 1/5th full speed where a series of clutches is employed. The field excitation may be reduced to obtain approximately half speed, and the motors may be connected in parallel to the supply with consequential adjustment of field excitation to avoid jolting, and then the field excitation reduced until full speed is obtained. On deceleration the excitation is increased causing the motors to act as generators until approximately half speed, the procedure for acceleration is then reversed and the vehicle finally brought to rest by mechanical brakes. Specification 599,887, [Group XXIV], is referred to.
