Title: Mechanism for maintaining constant tension in the bearing cable or cables of cable cranes movable on arcuate tracks
IPC: B66C21/00
Filed: 1952-08-19
Abstract: 722,563. Cranes. GES. FUR FORDERANLAGEN E. HECKEL. Aug. 19, 1952 (Sept. 20, 1951], No. 20782/52. Class 78 (4). To maintain a constant tension in the bearing cable or cables of cable cranes adapted to be moved on an arcuate track, the cable anchorage position is displaced according to the movement or position of a movable tower or the like on the arcuate track. As shown in Fig. 1, two bearing cables A, B have anchorages 3, 4 and towers 1, 2 moving along an arcuate track. As shown in Fig. 2, the bearing cable 6 is anchored to a movable trolley 7. A spindle 12 is driven by a gear 13, connected to the crane drive. The spindle carries a nut 14 the position of which therefore depends on the position of the crane and to which is pivoted a lever 18 having a roller 20 engaging the trolley 7. The lever also has a toothed sector engaging a gear 17 on a spindle 21, the movement of which controls a valve 23 supplying fluid to an hydraulic cylinder 10, the piston-rod 8 of which is connected to the trolley and controls the position of the trolley to maintain constant tension in the cable. As the nut 14 is moved, the lever 18 swings and rotates spindle 21 to operate the valve. Alternatively a motor drive may transmit the movement to the trolley. The trolley has nuts engaging a pair of spindles each having a gear engaging a common gear, which is driven by a motor in either direction. The shaft 21 as before controls a device to operate the motor in either direction and so move the trolley to maintain the tension constant in the cable 6.

Title: Arrangements for keying radio transmitters
IPC: H04L27/04
Filed: 1936-07-28
Abstract: 479,034. Wireless transmitting systems. STANDARD TELEPHONES & CABLES, Ltd. (Western Electric Co., Inc.) July 28, 1936, No. 20873. [Class 40(v)] In an arrangement for switching on and off the carrier in a high power radio transmitter, reversal of grid current due to secondary emission, causing unstable operation, is prevented by shunting the grid circuit resistance with a rectifier. The telegraph signals from source 2 operate relays 10 and 11 which connect the grids of amplifiers 5, 6 normally blocked by bias sources 14, 18, to suitable operating potentials over resistances 13, 17 and associated condensers 22, 23. Secondary emission from the grids of amplifier 6 may cause reversal of grid current in this stage, and resulting positive bias is prevented by shunting the resistance 17 with a rectifier 24 suitably of the mercury vapour type, which effectively short circuits the resistance 17 for reverse current. The rectifier also carries the main current when the relay contact breaks, and so prevents excessive sparking.

Abstract: 721,740. Semi-conductor devices. WESTERN ELECTRIC CO., Inc. Nov. 29, 1950 [Nov. 30, 1949], No. 21282/53. Divided out of 721,671. Class 37. A transistor comprises a semi-conductor body of one conductivity type having a zone of different or opposite type conductivity which forms a restricted path for the transfer of electric charges between the emitter and collector electrodes. Figs. 1 and 2A show a transistor comprising a block 20 of strong N-type germanium or silicon having a zone 21 which consists of weak N-type material, which may be produced as described in Specification 721,671. The base electrode 22 of copper or rhodium is plated on one end of the body 20 and the emitter 23 and collector 24 consists of point contacts engaging zone 21. Signals applied between the emitter and base electrodes provide output signals in load 28. Zone 21 offers a low-resistance path to holes injected at emitter 23 and hence restricts their path to reduce electron-hole recombination effects and equalize the transit times which facilitates operation at high frequencies. Alternatively, zone 21 may consist of P-type material, and collector 24 is then placed on the N-type body adjacent the P-type zone so that current multiplication is increased. An additional electrode may also be provided in contact with zone 21, so that an electric field may be provided between this and the base electrode to modify the transit time of holes flowing between the emitter and collector as described in Specification 700,236. Modifications are described in which the zone 21 is curved and is provided with a plurality of collector electrodes, or of emitter electrodes, or the zone may be arranged to branch into two portions each having a collector or an emitter electrode. Such arrangements may be used for mixing signals, or to provide control of amplification or a plurality of output signals. A magnetic field may be used to direct the flow of carriers to a selected collector electrode. N-type or weak P-type zones may also be produced on a P-type semi-conductor body. Further modifications are described in which the emitter and collector connections are provided by parallel zones of P-type material extending across the weak N-type zone 21, or by pointed or chamfered bodies of P-type material engaging the zone 21. The zone 21 may be situated in a corner of a triangular prism of strong N-type material, the emitter and collector then consisting of wires across the edge of zone 21, Fig. 5 (not shown). The collector and emitter electrodes may be on opposite sides of a semiconductor body, as described in Specification 700,232, the zone 21 extending between them, and with the base electrode being either at one end of the body or surrounding one of the other electrodes. Specifications 592,260, 592,303, 632,942, 632,980, [Group XL (c)], 694,021, 694,041, [Group XL (b)], and 700,241 also are referred to.

Title: Improvements in and relating to hydraulic power transmission means
IPC: B23Q5/26
Filed: 1931-07-28
Abstract: 380,212. Hydraulic transmission of power. JONES & LAMSON MACHINE CO., Springfield, Vermont, U.S.A.-(Assignees of Flanders, R. E. ; Cherry Hill, Springfield, Vermont, U.S.A.) July 28, 1931, No. 21588. Convention date, Aug. 26, 1930. [Class 69 (ii).] Hydraulic power transmission means for actuating mechanism has a pair of continuously driven pumps, and an accumulator in connection with the pumps for controlling the delivery of liquid to the driven motor, by operating means for byepassing one or both pumps. The pump structure comprises two gear-wheel pumps with a common inlet 65, Fig. 2, and separate outlets 70, 71, leading past check valves 72, 73 to a chamber 100, Fig. 5, and the inlet pipe 14 of a control valve 13, Fig. 1. The chamber 100 communicates with a hydraulic accumulator cylinder 102, the plunger of which is connected to a crosshead 115 loaded by springs 123 and is provided with a pin 111 acted on by a spring 108. The mechanism has a motor cylinder 6 and a metering device 17, which may be constructed as in Specification 352,809, and is adapted to be byepassed by a valve 20. When the valve 13 is operated to open one end of the cylinder 6 to the exhaust and the metering device is byepassed, the piston 7 moves, thus relieving the pressure in the accumulator. The loading springs then move the crosshead and plunger 104 to their extreme left-hand positions shown in Fig. 12 ; the crosshead compresses a spring 190 and moves a bar 126 having a rack 135, Fig. 6, engaging a pinion on the spindle of a valve 85. The valve is thus turned into a position such that both pumps deliver liquid to the motor. When the valve 20 is closed so that the metering device is in operation, there is resistance to the movement of the piston which lowers the rate of use of liquid in the cylinder 6. The excess liquid passes into the accumulator and moves its plunger to the right, so that the valve 85 is operated to byepass one pump. The other pump has a discharge greater than the rate of discharge of the metering device, so that the accumulator plunger is gradually forced farther to the right, until the valve 85 is operated to byepass this pump also. Following this, liquid is supplied to the motor from the accumulator only, its plunger then moving to the left and again bringing the second pump into action. In order to prevent hunting or flutter of the valve 85, the rack 135 has a lug 145 engaging a roller 146 carried by a spring-pressed member.
