Title: Improvements in dynamo electric machines
IPC: H02K9/06
Filed: 1919-02-10
Abstract: 137,635. Mossay, P. A. H., Jacoby, H. C. E., and Enclosed Motor Co. Feb. 10, 1919. Dynamos and motors, cooling. - Relates to totally enclosed dynamo-electric machines of the type described in Specifications 110,269, 119,505, and 120,241, in which the internal hot air of the machine is circulated through channels beyond the field periphery in contact with the walls of other channels through which cooling-air is passed, and consists in providing an end cover so constructed as to render the bearing easily accessible and free to be cooled by the air passing to the exterior channels. The end cover 9 is formed with an annular chamber 10 for accommodating the fan 13, and with conduits 11 which connect the chamber 10 with the cooling-channels 2 in the machine casing. The air is drawn in through the spaces between the conduits 11. The machine is provided with an end shield 4 with openings 5 corresponding with the. cooling-channels 2, and against which abuts an annular chamber 12, preferably of semicircular cross-section. A sheetmetal plate 15 may wholly or partly close the end of the cover. The end shield 4, cover 9, and bearing casing 8 may be formed in one casting.

Title: Logarithmic amplifier
IPC: G06G7/24
Filed: 1956-02-01
Abstract: 798,423. Electric analogue calculating systems. HUGHES AIRCRAFT CO. Feb. 1, 1956 [Feb. 2, 1955], No. 3231/56. Class 37. [Also in Group XL (c)] In a multi-stage amplifier comprising a number of pairs 10, 11 of stages and an output stage 12 providing an output logarithmically related to the input, a pair of stages 10 comprises discharge tubes T1, T2, the grid current from the tubes being combined in a common load circuit 62, the gain of each stage 10 being controlled by grid currents in the second stage 11. The anode circuit of each tube is impedance-capacitor coupled to the grid circuit of the next and the final tube T5 feeds a diode rectifier 46 associated with a tuned circuit 48. The grid circuit of tube T1 includes an inductor 16 earthed for signal frequencies by capacitor 18 and a grid resistor 50 connected to the common load 62. Similar provision is made for the remaining tubes and the anode connection of diode 46. Diodes 64, 66, 68 are also provided between the earthy ends of the grid coils in each stage. For a small input the tubes T1 ... T5 operate in a linear manner and current passes only through diode 46 and thus through resistor 60 and the combination of resistor 58 and diode 64 in parallel. By this means the tube T5 tends to be biased more negatively thereby altering its response. With increased signal, tube T5 is ultimately driven into grid current. The process is continued in a similar manner in the pairs of stages 11 and 10 until the tube T1 is also driven into grid current.

Title: Improvements in the manufacture of tubes of aluminium and aluminium alloys, either as the sheaths of electric cables or otherwise
Inventor: HOLLINGSWORTH DOUGLAS TAFT
IPC: B21C23/32
Filed: 1950-02-08
Abstract: 686,776. Drawing tubes. BRITISHINSULATED CALLENDER'S CABLES, Ltd. Feb. 7, 1951 [Feb. 8, 1950], No. 3285/50. Classes 83 (ii) and 83 (iv). In drawing aluminium or aluminium alloy tubes to size, e.g. closing a sheath on to an electric cable, a lubricant which subsequently forms a permanent part of a corrosion-resistant layer is applied at the die. Examples of suitable lubricants used in drawing down aluminium sheaths over electric cables are bitumen, which may be heated, and basic zinc chromate suspended in linseed oil. The same lubricant may also be applied to the die used for circularizing the tube before the insertion of a cable. The thin coating produced may be built up to the required thickness with the same or different materials.

Abstract: 1,212,085. Resiliently mounted seats. H. C. FLINT. 23 Jan., 1968 [10 March, 1967], No. 3421/68. Headings A4J and A4U. In a seat supported by frontally pivoted arms 38 and weight-bearing leaf springs 58, the back-rest 16 can be moved into a tilted position, by reversing links 86 about pivot pins 30. In the upright position of the backrest, the pivot pins 30 lodge in the crooks at the ends 40 of arms 38, so that the arms oscillate thereabout. On moving handle 98 anti-clockwise, cam 26 lifts the links 86, so that rearward pressure on the back-rest can bring it into the inclined position, in which links 86 engage stops 88 and the rear ends of arms 38 abut the springs 58 near their pivotal connections 62 to plate 46. In this position, pins 86 become the effective pivots of arms 38. A tension spring 90 assists the return of the back-rest to the upright position. The back-rest is pivoted at 74 to the plate 46, so as to be foldable over the seat.

Filed: 1972-01-25
Abstract: 1368351 Using masks in vapour deposition or sputtering HOCHVAKUUM DRESDEN VEB 25 Jan 1972 3506/72 Heading C7F Coating patterns 8 are produced on a substrate 6 by means of vapour-coating or cathode sputtering, jets 7 of the material to be applied being directed through a mask resting on the substrate, said mask consisting of a sieve fabric 1 on which a masking structure 3 has been applied by photochemical methods. The fabric may have mesh size 60-100Á, and wire thickness 30-50Á, and the mask 3 is applied photographically either by applying a negative photo-chemical structure 3, or by applying a positive photo-chemical structure, blocking the remaining sieve parts, e.g. electrolytically, and then removing the photochemical material. The mask may be covered with a protective layer 4 such as Cr applied by vapour deposition; this facilitates cleaning of the pores of a used mask by etching. In an example, a substrate of phenolic resin 5 plus adhesion-promoter 6 is coated with Cu by vapour deposition. A large area or moving jet source is preferably used; the substrate may move relative to the source.

Title: Direct current regulation with control rectifiers, in particular for rail motor-vehicles
IPC: H02M7/15
Filed: 1933-02-08
Abstract: 419,434. Converting. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Feb. 8, 1933, No. 3891. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 10, 1933]. Drawings to Specification. [Class 38 (ii).] Relates to grid-controlled rectifiers provided with groups of anodes which may be connected to various tappings on the supply transformer to render possible a large range of voltage regulation and consists in permitting the anodes connected to the low voltage tapping to function while current flow through the anodes connected to the high voltage tapping is being regulated. Each low voltage anode will thus conduct current for that part of the half cycle during which the high voltage anode is blocked. By this means the P.F. at which the arrangement operates is improved. Over the lower part of the voltage range the higher voltage set of anodes are permanently blocked. In addition groups of anodes can be connected to operate in parallel. The Specification describes the arrangement of a distributer for the grid potentials and gives the sequence of operations necessary to raise the voltage from zero to the maximum.

Abstract: 813,946. Electromagnetic switches. BRISTOL CO. Feb. 5, 1957 [Feb: 10. 1956], No. 3942/57. Class 38 (5). A synchronous contactor similar to that of Specification 703,772, wherein a pair of contactcarrying armatures 24, 25 are energized by a magnet structure 15, 16, 19 and electromagnet 20, 21 energized by A.C. so as to oscillate between contacts of respective pairs 32, 34 and 33, 35, is provided with a closed loop 37, around one of its armatures 24 so as to delay its operation with respect to the other. The loop may alternatively comprise a winding in series with an adjustable resistance to allow variation of the amount of contact lag. With the moving contacts 26, 27 interconnected by external means and the operating coil 21 energized through a phase-shifting transformer (Fig. 9, not shown) it is possible to arrange the circuit as in Fig. 6 such that with an input voltage applied to terminals E, a measure of the peak voltage of the wave is obtained as a series of pulses at terminals C. The contacts 32, 35 may be connected to separate terminals A, B (Fig. 2) so that positive and negative output may be separated. In Fig. 7 the loop 37 delays the contact 26 so the contactor acts as a single-pole, make-before-break, change-over switch. The moving contact structure is connected to a terminal H whereby output circuits are closed alternatively between H, F and H G with a slight overlap due to the delay.
