A dynamo-electric machine has a plurality of poles 10 and a squirrel-cage amortisseur winding comprising at each pole a pair of axially extending flanking bars 20 adjacent opposite circumferential sides of the pole and rigidly connected at their axial ends to respective. end rings 22, 24 of the winding, and a plurality of axially extending bars 18 spaced circumferentially between the flanking bars 20 and retained radially by extending through or partly into the end rings 22, 24 but being free to expand axially with respect to the end rings to which they are electrically and mechanically connected by respective flexible connectors 38 which permit differential thermal expansion of the bars 18 during machine operation. The winding is as is provided for starting synchronous motors and damping alternators, and the end rings shown are each divided into segments 26, 28, 30 interconnected by plates 32 and bolts 36. The connectors 38 shown in Fig. 2 are L-shaped laminations brazed to the ring segments and bars 18, but in modifications comprise bifurcated S- shaped members and flexible auxiliary segments.

Abstract: 1356323 Schottky barrier devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Aug 1971 (29 Aug 1970] 40092/71 Heading H1K A metal layer adherent to and forming a Schottky barrier with one face of a semi-conductor body extends in all directions beyond the edge of the face. Diodes embodying such a layer can be made in multiple from a 111 orientated wafer of 0À008 ohm. cm N-type silicon with a 7Á thick 0À8 ohm. cm. epitaxial layer on one face by depositing on said layer a 0À1Á layer of palladium, a 0À5 Á layer of gold and a copper (or silver or aluminium) support layer to form a Schottky contact, reducing the wafer to a thickness of 50 Á by etching and then applying similar palladium and gold layers to form an ohmic contact on the etched face. Isolated areas of the face are then masked with photoresist and the unmasked parts of the ohmic contact and silicon etched away to provide tapered mesas 2 (Fig. 8) of silicon. The copper support is next subdivided to provide individual diodes and the undercut edges 11 of the ohmic contacts removed by a blast of compressed air. Each diode is then soldered via its copper support to the header of a metal ceramic encapsulation. If thicker layers of palladium and gold, which may be replaced by a single layer of nickel or palladium, are used no copper support is necessary. If beryllia is used as a support a contact must be attached to the extending part of the Schottky contact layers. When gallium arsenide is used as semi-conductor titanium is used for the Schottky contact. The described Schottky barriers may also be used as the collector of a transistor and in thyristors.

Plastic material is fed from hopper 15 by conveyer screw 16 and is discharged through injection nozzle 13. Conveyer 16 has three parts namely 22, 23 and 24. The root diameter of the thread is greater at 22, less at 23, and greater again at 24. The material fed by part 22 only part-fills the thread when it reaches part 23, thus permitting a high-speed of rotation of the screw, the material then being compressed at part 24 and passing through apertures in piston 17 and past valves 19 into chamber 12. As material fills chamber 12 the screw 16 is forced backwards by the material and thereafter screw 16 is moved bodily forward to inject the material through nozzle 13.

Abstract: 964,894. Electrical selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 1, 1960 [Dec. 29, 1959], No. 41278/60. Heading G4H. A printing apparatus operating from a binary pulse input, comprises a plurality of print elements e.g. a series of hammers 16 actuated to print a character by striking a type element 12 carried on an endless band 10, a first memory means for storing an indication that one of said elements is to be actuated, a second memory means for storing an indication that one of said elements has been actuated, and compare means for comparing the first and second memory means to check that the correct element has been actuated. The printing elements are each controlled, and operate to print, upon the coincidence of electrical signals derived from a first storage e.g. a magnetic drum 46 whose speed of rotation is in synchronizm with the type band 10 which stores an indication of which type element 12 is opposite which hammer 16 as the band is moving, and electrical signals from a second storage device which stores an indication of the characters of a line to be printed As described this second storage device is a three dimensional array of magnetic core storage elements 20 and information is written into different positions from a data input channel 22 under control of a plurality of X switches 24 and Y switches 26 which selectively energize the X<SP>1</SP> and Y' lines wired through the cores, B and A memory rings 28, 30, clock 32, oscillator 33, and inhibit latches 36 through inhibit lines 37 to determine whether a core position is written when the X and Y lines are energized. Readout from the core storage elements 20 is associated with a compare counter 42 operated by a scan counter 44 from the first storage shown as the drum 46. The output of the compare counter 42 is fed into a compare circuit 48 and compared in response to a print scan signal, clock signal with the output from the incoming signals. The compare circuit 48, a regeneration circuit 50, and the memory rings 28, 30 ensure that the right hammer 16 is operated when, during a print scan operation an equal condition exists between a character in the storage 20 and a character on the type-band 10 for a particular print position. At the same time as a hammer 16 is fired an equal check plane 60 resets a corresponding core and the corresponding cores in a hammer fire check core is set. An error check scan is made on the next print scan cycle and if all the cores are not set in one position an error signal is produced and stored in a third memory means so that the printing apparatus will stop.

[Also in Division H2] A voltage regulating rectifier circuit comprises A. C. input terminals 1, 2, a controllable rectifier bridge including thyristors SCR1, SCR2, a smoothing filter L, C, and D. C. output terminals 3, 4, a series circuit constituted by a resistor R3, a saturable reactor SR and a voltage reference source Vr being connected across the output of the rectifier bridge. The junction of R3 and SR is connected via resistors R1, R2 to the triggering electrodes of SCR1 and SCR2 respectively. The output voltage, or a sample thereof, and the reference voltage are applied in opposition to the winding of the reactor SR, saturation of which causes triggering of the rectifier circuit; for this arrangement, the Specification shows that pre-setting of the reference voltage to a given fixed value presets the output voltage to the same value. Several modifications are described with reference to Figs. 3 to 18 (not shown). For example, the reference voltage may be derived by way of a Zener diode from the A. C. supply or from the D.C. output of the rectifier bridge; to reduce the power requirements of the reference source a split saturable reactor may be employed, or further thyristors may be used in the triggering circuit; and a current limiting circuit may be provided.
