Title: Apparatus for determining direction of signals in lines
Inventor: LEMAN HUGH SPENCE
IPC: H04M9/00
Filed: 1961-07-28
Abstract: 969,916. Telephone transmission systems. STANDARD TELEPHONES & CABLES Ltd. July 28, 1961, No. 27511/61. Heading H4R. In an arrangement for determining the direction of a signal in a line, an attenuating resistance R is provided therein and the signals on each side of the attenuator are differentially amplified by transistors TR1, TR2 whose outputs each of which are determined by the difference in the input signals voltage are then compared. As shown, the outputs from the transistors are applied to voltage doublers D1 D4 and D2, D3 whose outputs, which are of opposite polarity, are combined to produce an output OP. By suitable choice of R in relation to the other parameters of the circuit, it can be arranged that for any direction of transmission only one of the transistors provides an output. The output OP is then positive or negative according, to the direction of the signal. The arrangement may operate over a wide range of amplitudes, the doubler circuit for one transistor operating as a voltage limiter for the other. In a modification, Fig. 3 (not shown), the transistor outputs are taken off, via transformers in the collector circuits, and fed to bridge rectifiers. '

[Class 2 (iii)] In the alkylation of tertiary saturated hydrocarbons with olefines in the presence of a liquid catalyst such as sulphuric acid, a mixture of the initial hydrocarbons is introduced into a circulating emulsion of tertiary hydrocarbon and catalyst so as to give a ratio in the mixture of tertiary hydrocarbon to olefine (by volume) of at least 30:1, the mixture being passed through a reaction zone after which a part is drawn off and the remainder recycled. Preferably the ratio of tertiary hydrocarbon to olefine in the feed is at least 4:1, the ratio of catalytic liquid to olefine is at least 50:1 and the ratio of catalyst to total hydrocarbon is between 1:3 and 3:1.

Abstract: 1432463 Bearings HUGHES TOOL CO 11 June 1973 [12 June 1972] 27751/73 Heading F3A [Also in Division C7] In the manufacture of earth-boring drill bits having a cutter rotatably mounted on a journal by a friction type bearing having steel mating surfaces one or both of those surfaces is gas carburized in an atmosphere having a carbon potential such that free carbides are produced and is then quenched directly from a carburizing atmosphere without loss of carbides. The quenched component may then be tempered and/or coated with an anti-galling solid lubricant, particularly a metal or metallic compound such as iron sulphide or manganese iron phosphate. As particularly described the bearing surfaces were carburized at 1700-1710‹ F. in an atmosphere with a potential of 1.35 for nine hours, cooled in the same atmosphere to below 800‹ F. and air cooled. It was then reheated to 1500-1510‹ F. in an atmosphere of potential 1À00, held for 30-45 minutes and oil quenched. at 70-140‹ F. before tempering at 325-340‹ F. The product had a surface carbon of 1À21%. In a particular form of bit the cutter head 15 rotates on journal 11 about an axis 21, and the bearing surfaces 39 are carburized. Lubricant is supplied through passage 25 to annular cavity 26 where it is retained by 0-ring 27. In a further embodiment (Fig. 2, not shown) the head is supported by a combination of ball and friction bearings.

Abstract: 279,456. British Thomson-Houston Co., Ltd., (Assignees of Rich, T. A.). Oct. 19, 1926, [Convention date]. Electromagnetic current and pressure meters having fixed and movable magnetic vanes 11, 12 are energized by a pair of coils 10<a>, 10<b> placed one inside the other and connected to produce fluxes in opposite directions through their axes and in the same direction in the annular gap between the coils. The coil 10<b> may be slightly eccentric to the coil 10<a> so that a crescent-shaped annular airgap is provided between them, in the larger portion of which the vanes 11, 12 are situated. The coils 10<a>, 10<b> may be so proportioned that the flux inside the inner coil 10<b> is reduced to zero. The stationary vane 11 is of tapering width so that the movable vane 12 is repelled against the action of a spring 14 with a force varying according to its position. The instrument is stated to have low inductance and small frequency error. The same principle may be applied to instruments of the attraction type having the relatively movable vanes arranged axially instead of radially with respect to each other.

Abstract: 709,256. Gas turbine plant. GENERAL MOTORS CORPORATION. April 30, 1951 [May 15, 1950], No. 28056/52. Divided out of 709,210. Class 110(3) [Also in Group XXIV] A gas turbine plant, comprising a plurality of combustion chambers disposed in a circle around a shaft connecting a compressor to a turbine with the longitudinal axis of the combustion chambers parallel to the shaft, has two spaced coaxial cylindrical casings situated between the combustion chambers and the shaft so as to form a passage for the forced now of coolant fluid parallel to the shaft. Air is supplied from a compressor 22 through combustion chambers 26 to a turbine 40 which drives the compressor through a shaft 10 mounted in bearings 12, 14, 80. The combustion chambers are supported in extensions 36 of the compressor casing 16 and by an annular support 42. A cylindrical wall 32 extends from the casing 16 to the partition 30. A second cylindrical wall 34 concentric with and spaced from the wall 32 forms an annular cooling passage and heat shield around the shaft within the combustion chambers 26. A coriduit 38 secured to the support 36 supplies air to the annular passage between the walls 32, 34. The air leaving the annular passage 32, 34 flows through ducts 56 to the space between the first of the turbine rotor discs 54 and the partition 30. An annular baffle 58 directs the air inwards adjacent the bearing 14 and shaft 10 after which the air moves outwards to the blades 62 of the fan 60. A part of the air discharged by the fan 60 passes between the baffle 58 and fan housing 64 through openings 68 and over the combustion chambers and turbine stator to an atmospheric vent 48. The remainder of the air passes through apertures 72 and moves radially inwards to a passage 74 leading to an annular passage formed between the inside of the turbine shaft 21 and a thin sleeve 76. This air after cooling the oil in the supply conduit 81 in the bolt 82 and the return conduit formed between the bolt 82 and the sleeve 76 passes through the passage 84 to the space between the last rotor disc and the partition 118 and thence into the turbine exhaust stream. The Specification also refers to the subject-matter of Specification 709,210.

A brake for a vehicle comprises a manually actuatable brake means which engages a common brake drum 7 independently of the foot brake, in which the manually actuatable brake means includes a wedge section brake segment 15 co-operating with friction surfaces 17, 18 arranged on the circumference of the brake drum 7 and inclined to each other at an angle. The wedge segment 15, spring mounted between web portions 19, 20 of a sheet metal cover 21, is actuated by a lever 26 having a bifurcated leg 33, 34 and being pivoted on a bar 29 and a Bowden cable 42 acting through an intermediate lever 40 and spring- loaded ball 46. The actuating levers are restrained by a spring 30. Lever 26 incorporates a wear-adjustment device comprising a disc 37 frictionally held on bar 29 by a spring washer 38 and one arm 34 of lever 26 carrying a projection 35 which cooperates with a recess in disc 37. When no wear has taken place the projection 35 moves in the recess but does not engage the disc. When wear has taken place, however, on applying the brake, projection 35 engages disc 37 and rotates it against the force of washer 38 and, on release of the brake, disc 37 remains in its adjusted position. Spring-loaded ball 46 moves upwardly in grooves 47, 48 of levers 40, 26 to compensate for the greater separation of these levers. The foot brake comprises brake shoes 10 acting on friction surfaces 8, 9 on the drum 7 and is actuated by a link 11 and hydraulic piston 12.
