Title: Improvements in or relating to dynamo electric machines
IPC: H02K19/24
Filed: 1959-12-01
Abstract: 914,648. Alternators; automatic voltage control systems. MACFARLANE ENGINEERING CO. Ltd., and MACFARLANE, W. I. Nov. 9, 1960 [Dec. 1, 1959], No. 40738/59. Classes 35 and 38 (4). Machine construction.-Between the stator output winding 24 and the stationary exciting field winding 12 of an alternator an interdigitated rotor rotates with shaft 22. The interdigitated poles 17, 16 extend radially from pole-rings 18, 18A and then axially 17A, 16A in opposite directions in the air gap between the exciting and output coils, non-ferrous spacers 19, 19A mechanically couple pole-ring 18A to the driven pole-ring 18. The exciting coil support tube 13 which has a passage for wires 23 is separated by small air-gaps 20, 21 from both pole-ring 18A and shaft 22 to ensure adequate mechanical clearance. Flux passing along shaft 22 is prevented from causing circulating currents in the bearings by bushing coils 26. To eliminate axial flux in the shaft two stators carrying common windings and co-operating with a double rotor having two exciting windings producing opposing m.m.f.'s and supported from opposite ends of the frame, may be employed. Construction of a machine having a planar air-gap and having the exciting winding attached to the outer yoke are also described. In special cases laminated poles and/or an amortisseur winding may be used. Control circuit.-The alternator may be of the self-regulating type having the alternating current supplied to field 80 controlled by varying the voltage applied to points GC on the controlled silicon rectifier 81. A reference voltage appears at the mid-point of one limb of a bridge comprising a resistor 87 and Zener diode 88, while the voltage appearing at the midpoint of a choke 91 and resistor 90 comprising the other limb varies linearly with alternator output 89. The voltage difference between the mid-points of the bridge controls rectifier 81 and the current in field 80, discharge of the field through rectifier 83 gives some continuity of field current. The supply 82 may be derived from either a transformer across the output of the alternator or from a pole face winding in the armature slots.

Abstract: 1408183 Brushgear WESTINGHOUSE ELECTRIC CORP 4 Sept 1972 [29 Oct 1971] 40868/72 Heading H2A In a brush assembly for a dynamoelectric machine, two brush parts 12 are joined together by a resilient member 15 whose unstressed shape is curved, as in Fig. 2, so that when the brush is mounted in a holder 10 the parts 12 are subjected to opposed forces 17 and are urged against the inner surfaces 16 of the holder. In the arrangement of Figs. 5, 6 '(not shown), a corresponding resilient member (48) is planar when unstressed, but is bent into a curve when in the holder. In the arrangements of Figs. 3, 4 (not shown), the brush parts are acted on by a part of coil springs (28) or by a leaf spring (42).

Title: Acylation of amines
IPC: C07C233/00
Filed: 1958-12-19
Abstract: A process of acylating an aminoaryl sulphide comprises a Schotten-Baumann reaction in which an aminoaryl sulphide is reacted with a mononuclear aromatic acyl chloride in an aqueous medium containing alkali and providing in the medium at least during the acylation of the last 10%-15% of the amine a chloride ion concentration of at least 1.5 gm. ions/litre.  The high chloride ion concentration is said to reduce the hydrolysis of the acyl chloride. The desired chloride ion concentration may be provided by adjusting the initial water content of the reaction with respect to the soluble metal chloride formed in situ or by the addition of a water soluble chloride to the aqueous medium. In examples o,o1-diamino-diphenyldisulphide is benzoylated.

Abstract: 1,263,127. Integrated circuits. INTERNATIONAL BUSINESS MACHINES CORP. 19 Aug., 1969 [5 Sept., 1968], No. 41319/69. Heading H1K. An individual isolation wall surrounding each component in an I.C. is produced by diffusing a first region of the opposite conductivity type into a substrate, depositing a first epitaxial layer of the same conductivity type as the substrate, diffusing a frame region of the opposite conductivity type through the layer to contact the first region, depositing a second epitaxial layer, and diffusing a second frame region through this layer to contact the first frame region. An N--type Si wafer (10) is thermally oxidized and the oxide photolithographically processed to provide openings into which an impurity is diffused to form P-type isolation regions (12), Fig. 2a (not shown). The surface is reoxidized and all the oxide removed and an N--type epitaxial layer (16) is deposited by the hydrogen reduction of SiCl 4 , Fig. 2b (not shown). The surface is oxide masked and impurities are diffused-in to form an annular P-type region (18), Fig. 2c (not shown), and an N<SP>+</SP>-type subcollector region 20, Fig. 2d (not shown). A second N--type epitaxial layer 22 is then deposited and a P-type annular region 28, and N<SP>+</SP>-type collector contact region 24, a P-type base region 26 and an N<SP>+</SP>-type emitter region 32 are formed by diffusion. During subsequent epitaxial growth and diffusion steps the impurities in P-type regions 12 and 18 and in N-type region 20 diffuse into the overlying layers so that the transistor is completely surrounded by a P-type isolation region and the region 24 contacts the sub-collector region 20. The N<SP>+</SP>-type collector contact region 24 and the emitter region 32 may be doped with phosphorus. The base region 26 may be formed simultaneously with the P-type isolation region 28. A low resistance cross-over may be provided in the wafer by forming a P-type "column" simultaneously with the three isolation region diffusions, conductive tracks in one direction passing over the "column" on an insulating layer while a track extending at right angles to the first direction is broken and has its ends in contact with spaced parts of the top of the "column" which completes the circuits, Fig. 3 (not shown).

Closure means for an opening in a pressure vessel comprise two portions 1 and 2 which can move relatively in a direction axial to the opening, and locking members 5 which are withdrawn when the portions are fully apart but are extended when the portions are approached, an interlocking means 14 being also provided which indicates by its position when the members 5 are extended in locking position. In the construction of Fig. 1 the hooks of a lifting grab are engaged under a surface 12 at the upper end of the closure means. Movement of the interlocking means 14 will prevent the grab being disengaged until the members 5 are fully extended in the locking position for the closure means. In the arrangement shown in Fig. 3, the lifting mechanism is operated by lowering a member 26 to permit wheels 28 and 29 to engage and operate a control shaft. Member 26 is restrained by an interlock plate 32 which is locked against movement by dowel pegs on member 22 (which corresponds to portion 2 in Fig. 1) when this is moved away from portion 1. A further safety interlock is shown in Fig. 3. A member 41 is connected to portion 1 and a further member 44 sliding in member 41 is connected to portion 22. A grab hook 46 can only be connected or disconnected when the members 1 and 22 are together and the members 41 and 44 are therefore at their maximum separation. In the construction shown in Fig. 6 sealing arrangements are operated by an actuator member 54. A grab cannot be inserted into portions 1 and 2 for lifting, unless balls 71 can be pressed back into the apertures they are seated in, and interlocking members 70 can move past a waist portion 72 in member 54. Specification 874,640 is referred to.
