Abstract: 961,975. Electron beam parametric amplifiers. WESTERN ELECTRIC CO. Inc. Oct. 27, 1960 [Nov. 19, 1959], No. 36882/60. Heading H1D. An electron beam parametric amplifier comprises means, e.g. cavity resonator 19 or a Kompfner-dip helix, for causing pump frequency energy to propagate along the beam as a fast space charge wave, means for causing signal frequency energy to propagate along the beam as two growing fast space charge wave having different velocities which means comprise a slow wave circuit 21 in coupling relationship with the fast modes of the beam and the fast space charge wave pump frequency energy, wherein the slow wave circuit periodically with respect to distance introduces to and extracts from the fast modes of the beam the signal energy and noise energy, the transferrals of the signal energy and noise energy being substantially 180 degrees out of phase with respect to distance, whereby substantially all of the noise energy exists on the beam at a position at which substantially all the signal energy exists on the slow wave circuit, means 42 being located at such a position for extracting amplified signal energy from the amplifier. The pump frequency is preferably twice the signal frequency, and the transferrals of the signal energy and the noise energy between the beam and the slow wave circuit are produced by causing the two growing waves to beat together. The slow wave circuit 21 may be a helix as shown, or a series of coupled resonators. Specification 832,172 is referred to.

Title: Apparatus for returning empty bottles or other returnable wrappings
IPC: G07F7/06
Filed: 1955-12-23
Abstract: 820,024. Coin-freed apparatus. SERV-O-MATIC A. B. Dec. 23, 1955 [Dec. 23, 1954], No. 36957/55. Class 27 Apparatus for receiving empty bottles or other returnable wrap pings and issuing a coir or receipt or the like in return has a pivotec jaw cradle or grab 4, 5 connected by a cable 37 to a pneumatic dashpot 42, the cradle falling under the weight of ar inserted bottle anc opening automatically to deposit the bottle Access to the cradle is obtained through a pivoted shutter 56 which is operable only on insertion of a toker supplied when the filled bottle was sold. An inserted toker forms an abutment con necting a push-button slide to a slide 68 from a notch 70 on a shutter plate 61 which moves rearwards to release a pawl and to bring an abutment 130 into the path of a pawl 89 engagable with a ratchet 86 connected to a spring-loaded level 79. The shutter 56 can then be opened and a roller 65 carried by the plate 61 moves the lever 79 rearwardly until the abutment 130 moves the pawl 89 to lock the shutter in open position. Until the bottle is inserted far enough to rest wholly on the cradle, it lifts a pivoted plate 94 and a stop 96 is placed in front of the roller shaft 64 to prevent closing of the shutter. Release of the push-button releases the pawl 89 and the shutter is then closed by the spring loaded lever 79. The cradle descends until it hits the bottom of the container and the inertia of counterweights 14 on shafts 11 rotate the shafts to release latches holding the jaws 4, 5 closed. Cam surfaces 19 on the jaws prevent them from wedging between any bottles there may be at the bottom of the container and thus failing to open. As the cradle descends, the cable 37 rotates a worm shaft 39 and a springy tongue 46 engaging the worm 45 is moved to close a switch 49, thus operating a device D which delivers tokens from tubes 53, 54 into a tray 55. The emptied cradle rises again under the action of the closely fitting weight 43 in the dashpot 42. To prevent lowering of the cradle while the shutter is open, the lever 79 acts on a rod 31 and through an arm 33 and shaft 97 rotates a pair of wings 98, 99 into a horizontal position under a pin 34 on the cradle. To prevent opening ofthe shutter when the cradle is descending, a lever 83 normally resting on top of the cradle interposes, at its other end, a stop 83a in the path of a pin 82 on the lever 79.

Abstract: 1,194,586. Gas turbine plant-fuel supply. MOTOREN-UND TURBINEN-UNION MUNCHEN G.m.b.H. Aug. 14, 1967 [Sept. 27, 1966], No.37338/67. Addition to 1,138,165. Heading F1G. In a gas turbine plant, an endothermic reaction between the starting fuel and water takes place in a vessel separate from the combustion chamber, the reaction effecting a continuous conversion of liquid or gaseous hydrocarbon fuel with water in its liquid or gaseous phase to carbon monoxide and hydrogen, the combustible gas mixture so produced being supplied to the combustion chamber. The heat required for the reaction is taken from the working fluid of the turbine after it has been partially expanded, the gas extraction point being between two turbine stages, the gas temperature being as low as possible but sufficiently great to effect the endothermic fuel reaction. In the embodiment shown the hydrocarbon fuel and water mixture passes fron tank 1 to the heat exchanger 48 wherein the endothermic reaction occurs, the resulting combustible gas mixture passing to the combustion chamber 10 where the fuel is burned with air under pressure supplied by the compressor 23 and preheated in the air preheater 22. The combustion gases pass to the turbine 12 which drives the compressor 23, thence to the separate power turbine 14 which drives a generator 15. The turbine exhaust gases then pass to the air preheater 22 and finally discharge to atmosphere. A portion of gases is tapped from the turbine 12 and passed through line 29 to the heat exchanger 48 thus supplying the heat for the endothermic reaction, the portion of gases being returned to the turbine 12 through line 30.

Filed: 1961-10-24
Abstract: 1,019,902. Hydrodynamic transmissions. V. J. SIMPSON. Oct. 24, 1962 [Oct. 24, 1961], No. 38077/61. Heading F2C. A hydrodynamic torque converter .comprises an impeller 36 having axially disposed sets of blades 40, 41, and axially slidable to selectively position either set of blades in the working circuit or to withdraw both sets of blades from the circuit. The torque converter has a secondary member 21 fast with a shaft 23 which is connected through a one-way clutch 62 with a gear-wheel 61 which is geared to an output shaft 64 for forward drive, and a further member 31 which is fast with a sleeve 32 which is connected by a one-way clutch 68 to a gear-wheel 67 which is selectively stationed for forward drive and released and geared to the output shaft 64 for reverse drive, at which time the gear-wheel 61 is stationed. The impeller 36 is fast with a sleeve 37 which is supported by ball bearings 38 on the sleeve 32 and which is shifted axially by means of a servo ram (not shown) acting through a linkage and a bearing 53 on the end of the sleeve 37. The servo ram is subject to spring loading and to hydraulic or pneumatic pressure and urges the sleeve 37 and impeller 36 to the left to insert the sets of blades in the working circuit. The impeller 36 carries follower rollers 47, 48 which are engaged in helical tracks 45, 46 in a casing 8 which is fast with an input shaft 3. The helical tracks subject the impeller to a force tending to retract the blades from the working circuit. Under idling conditions the blades 40, 41 are withdrawn from the working circuit as shown in the lower half of the Figure. Wide opening of the throttle will cause the torque converter to go to a high torque condition in which blades 41 are inserted in the working circuit so that the vehicle will rapidly accelerate, and as the vehicle speed increases blades 40, which have different exit and entry angles to the blades 41, are inserted in the working circuit to give a low torque condition. During low torque working the blades 41 of the impeller are accommodated inside the core of the converter. In the extreme left-hand position of the impeller the torque converter is bridged by the frictional engagement of coned surfaces 59, 58 formed on the impeller and secondary member 21. A gear pump 11 is geared to the input casing 8 and supplies liquid to the working circuit, and a second combined gear pump 12 supplies hydraulic pressure to the servo ram. The gears 61, 67 are selectively meshable with a gear 63 slidably splined to the output shaft 64, detents associated with the gear shift mechanism engaging the gears 61, 67 to station them when the gear 63 meshes the other gear.

Abstract: 936,602. Extruding. SCHLOEMANN A.G. Oct. 26, 1961 [Nov. 18, 1960], No. 38328/61. Class 83 (4). A tube extrusion press has means for releasing and withdrawing the mandrel 8 and for inserting and securing therein a fresh mandrel. The mandrel 8 is secured to its holder 6 by a sleeve 7 which may include a bayonet joint. For changing the mandrel a double-acting cylinder 12 first raises a slide arm 11 which is then moved inwardly towards the press axis by a doubleacting cylinder 13. Fluid-actuated gripper jaws 16 carried by the arm then clamp the mandrel whilst a spanner 14 is rotated by a motor 15 to release the mandrel. Cylinders 12, 13 are then reversed to withdraw the mandrel and move it outwardly to a rotary carrier 19 which transfers it to an inspection and treating station 20. Fresh mandrels are collected by a further carrier 19a which supplies them to a second pair of gripping jaws and spanner on another arm 11. This is moved inwardly and upwardly to insert the new mandrel into sleeve 7, and secure it therein. The removal and insertion of the mandrels may take place automatically by electrical, hydraulic or mechanical control means initiated by retraction of the mandrel after each or every second and third extrusion strokes. Hand control may also be used. The arms 11 may be pivoted instead of slidable or a single arm may be used for both the removal and insertion operations.
