Title: Machine for moulding under pressure metal connecting members of rotors of electric motors
IPC: B22D17/00
Filed: 1969-01-09
Abstract: Into a machine for assembling rotors by casting squirrel cage bars B, Fig. 1, and end rings 9, 10 (which may have cooling fins) in and on stacks R of laminations 5, such a stack is allowed by a device 86, Fig. 8, to drop from a shoot 85, into a cleft 90, 91 (of a feed-slide 87, 88) adju stable to accommodate the stack diameter , and is carried sideways to align its axis with the horizontal axis 106 of hydraulic jacks 61, 62, Fig. 12, and of a sleeve 22 or 23 into which the stack R is pushed by the hollow rod 64 of the jack 62. The sleeves 22, 23 are mounted in a plate 19 which can be swung through 180 degrees by a rack-and-pinion 40, 39, Fig. 6 (or by gearing or an hydraulic motor) about a horizontal bar 16b of the machine, so that their positions, in the same horizontal plane, can be interchanged. Thus, while the sleeve 23 containing a stack R 1 , Fig. 12, is clamped between a fixed die 26 and a movable die 32, metal is injected by a plunger 30 through one or more gates 28 into annular cavities 27, 34 in the die faces and into helically arranged channels 8, Fig. 1, for casting the bars in the rotor. Meanwhile, from a completed rotor R1 in the sleeve 22, a temporary spindle 7, on which the rotor laminations have been stacked, is pushed out into the hollow piston rod 64 by an extension 65 of the piston rod 63 of the opposed jack 61 which, being of greater thrust, also causes the completed rotor to be pushed out of the sleeve 22, breaking the sprue C. The spindles 7 are pushed successively through the rod 64 until they fall into a shoot 82. The freed rotor R1 falls into a discharge shoot 80 on retraction of the rod 63. A lowerable stop 70 prevents retraction of the rotor with the rod 63. While the assembled rotor is still in the sleeve 23 between the dies, with the cast metal cooling, a fresh rotor stack R, Fig. 8, is carried into the machine and inserted in the sleeve 22. Then the injection plunger 30 and the die 32 are retracted and the sleeve-carrying plate 19 is moved off the fixed die 26 by a jack 43 and swung through 180 degrees by the rack-and-pinion 40, 49 to interchange the positions of the assembled rotor and the fresh stack, ready to start a new cycle. In a modification, Figs. 18-24 (not shown), an assembled rotor is pushed by a part-hollow piston rod (111) on to the opposed piston extension (116) to remove a temporary spindle (112) and against stops (117) to break the sprue while the metal is being injected into the stack in the other sleeve. The stop (70) is fixed on the side of a plate carrying the fixed die (26) opposite the hollow-rod jack and on which side the assembled rotor falls and is discharged.

Title: Electrically connected remote control for automatically tuned receiver
IPC: H03J9/00
Filed: 1969-08-12
Abstract: A remote control device for a radio receiver such as is disclosed in Specification 1,160,684, using electronic tuning means, and particularly automatic tuning and scanning means, comprises a combined on-off switch 51, Fig. 3, and volume control 52, a tone control 53 and a band selection control C, Fig. 4, which switches in frequency modulation tuner FM or amplitudemodulation tuner AM, two bands being covered in the latter by rendering conductive or non- conductive diodes, e.g. D2 shunting inductors L2: tuning is by means of varactor diodes, e.g. D 1. The arrangement also includes controls for manual tuning and for switching over from manual to automatic tuning, comprising a potentiometer 61, Fig. 5, and three-position switch 60, which in a first position provides manual tuning, the automatic tuning unit RA being connected to earth while the sliding contact of manual tuning potentiometer 67 is connected over emitter-follower transistor T1 to electronic tuning means comprising varactor diodes D3. In a second " auto " position of switch 60, automatic tuning occurs, the base of transistor T1 being connected by lead 64 to the automatic tuning unit RA, while a third position of switch 60 provides for scanning to commence. Unit D provides for switching between " distant " and "local" " station reception: for " local " reception on A.M. bands a low value resistance 108 is shunted across receiver filter circuit 112 during scanning, by means of diode 106 which is rendered conductive from the bistable circuit BS, becoming non-conductive when scanning ceases. On the F.M. band, the bi-stable circuit BS switches the collectoremitter path of transistor 136 in shunt with tuned circuit 142. In addition, on both bands the amplification of an R.F. amplifier transistor 170 is reduced by the application of a potential from bi-stable circuit BS to the base of transistor 160, rendering it non-conductive: the collectoremitter path of this transistor shunts the emitter-circuit resistor 172 of transistor 170.

Patent ES-428855-A1 (ES)
Title: Contact system for high-voltage power circuit breakers
IPC: H01H1/38
Filed: 1974-08-01
Abstract: A contact system for high-voltage power circuit breakers which includes at least one stationary, hollow, nozzle-shaped contact, comprising an electrically conducting tube made from copper or copper alloy and a nozzle body of arc-resistant material, such as graphite which is joined to the tube at the end face thereof. In the closed position the stationary contact is surrounded by a movable, tubular switching member with resiliently supported contact elements. The nozzle body has a larger outside diameter in the region of the joint compared with the diameter of the tube. When the switching member is drawn across the joint, the larger diameter of the nozzle body results in an increased pressure being applied thereto by the resilient contact members. Because of the characteristics of graphite the increased pressure results in a reduction of the resistance of graphite thereby improving the commutation of electric current from the tube to the nozzle and reducing the tendency to arc.
