Title: Improvements in or relating to speedometers
IPC: G01P3/12
Filed: 1923-10-23
Abstract: 205,832. Suffit, R. Courtois-. Oct. 23, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Impulse and momentum speed indicators.- The shaft or reciprocating member whose speed is to be measured drives a rotary member 4, Fig. 1, having teeth or a friction surface over part of its periphery engaging teeth or a friction surface of a wheel 1, which is advanced during the engagement of surfaces and returned during disengagement by a spring 2. Tappets 38, 39 on the wheel 1 engage a rod 40 on the index hand 3, which is mounted on an axis independent of and in alignment with the shaft of the wheel 1, and is retained by a blade spring 37 in a position corresponding with the mean position of the oscillating wheel. The wheel 1 may be returned by a spring-actuated sector 41, Fig. 8, the spring 42 of which, owing to its angular position, acts with increasing force as the speed increases; or a number of springs coming into action successively may be employed. The transmission shaft may be in alignment with the axis of the wheel 1, as shown in Fig. 9. In this arrangement the actuating pinion 4 is carried by an arm 43 on a driven shaft 7, and rolls freely on the wheel 1, except when an arm 46 on the pinion engages internal projections 45 on an enclosing ring 44, during which time the wheel 1 is advanced. The wheel 1 or the pinion 4 may be yieldingly mounted to prevent jamming during engagement. Speed-indicator transmission mechanism.-The member 4 may be rotated by a connecting-rod 23, Fig. 5, on an armature 21 of electromagnets 20, the circuits of which are closed by a rotary switch 16 on the speed shaft 15. Or one electromagnet and a return spring may be used. In another arrangement, a piston 26, Fig. 6, is reciprocated by pneumatic impulses transmitted from a speed shaft, and rotates the member 4 by a connecting- rod 27, while in a further arrangement, a cam 28, Fig. 7, on the speed shaft 15 rocks an arm 29 connected by an enclosed cable 31 with a connecting rod 36, the return being effected by a spring 35. The effect of dead centres is eliminated by means of a cam 14 on the member 4 engaged by spring pawl 12. A complete speed indicator with distance registering mechanism driven from the wheel of a bicycle is referred to in the Specification, but this subject matter is not illustrated.

Title: Improvements appertaining to the production of yarns or threads of fibrous substances
IPC: D02G3/14
Filed: 1928-09-19
Abstract: 326,786. Green, A. Sept. 19, 1928. Special yarns, producing; spindle apparatus; stopapparatus, non- automatic; brake arrangements; rollers. - Compound yarns comprising a core of horse hair or the like, alone or accompanied by a thread, and a binding-thread which may be artificial silk, are formed by means of a rotary tube or flyer 4 carrying a centrally disposed cop b<1> of binding-thread b, which is led through an eccentrically disposed guide c, Fig. 9, around the lower end of a funnel-shaped member 4<c> or beneath a spring on a disc to impart drag, and back to the axis of the tube or flyer where it encircles the core, the resulting yarn a<2> being led outside the tube and back again to the axis and wound in cop form by a rotary flyer 31, or in bobbin or cheese form on a bobbin rotated by two rollers. A false twist is imparted to the core between the feed rollers 2, 3 and the neck b<1> where the binding-thread engages the core; this action in conjunction with subsequent twisting action due to rotating the flyer 31 in the same direction and at half the speed of the tube 4, ensures an effective binding of the core. The tube 4 is provided with ribs engaging the interior of a driven tube 6 and is connected thereto by a cross pin 4<a> which also supports the hub 5<a> of the cop spindle 5, the hub being connected to the tube 6 by a spring-controlled ball. The bracket 8 which carries the tube 6 is mounted on a pivot 8<a> and is normally held in operative position by a latch 11. The apparatus is stopped by means of a hand lever 12, which releases the latch 11 and thereby enables the bracket 8 to tilt and slacken the driving.band and bring the wharl against a brake 26, and at the same time, operates a lever 10 whereby the corefeeding mechanism is disconnected by the link lOb, the feed rollers 2, 3 are separated by the link 13, and the delivery rollers 20, 21, which are used when winding the yarn into bobbin or cheese form, are separated by the link 17. The feed and delivery rollers are normally maintained in contact by springs 16, 22. The hairs are fed to the rollers 2, 3, by the mechanism described in Specification 316,116, [Class 142 (ii), Looms, Kinds &c.].

Patent GB-1301605-A (GB)
IPC: F02C7/30
Filed: 1971-04-19
Abstract: 1301605 Axial-flow compressors UNITED AIRCRAFT CORP 19 April 1971 [28 April 1970] 26868/71 Heading F1C A gas turbine engine having its fuel regulated to control the steady state operation and limit the acceleration and deceleration of the engine, has a control system which opens and closes bleeds of the engine compressor in accordance with corrected engine speed and with deviation from said steady state operation. A pistonoperated actuator 34 for opening and closing the compressor bleeds is shown in the bleeds open position. A three-dimensional cam 122 is moved axially in accordance with compressor speed and is angularly adjusted in accordance with compressor inlet temperature so as to be representative of corrected speed. When the latter reaches a predetermined value, e.g. 78%, lever 119 is moved clockwise by cam 122 sufficiently to cause valve 77 to vent pressure fluid from the right of piston 68 via lines 90, 86, 76. Thus spool valve 42 moves rightwards and reverses the high and low-pressure fluid connections to the opposite sides of actuator piston 36 whereby the latter moves rightwards to cause closure of the compressor bleeds. If now the deviation above or below the engine steady state condition exceeds a certain percentage within the confines of the  acceleration and deceleration limits, as sensed by comparison of the movement of lever 140 of the fuel regulating means and the movement of cam - actuated lever 150, then lever 134 is pivoted about pin 152 to throttle either one of valves 115, 116 which normally vent pressure fluid supplied via lines 102, 104, 106. Thus the space at the right of piston 68 is repressurized via lines 110, 90 and selector valves 162, 108, causing reopening of the compressor bleeds. When the corrected speed exceeds a high predetermined value, e.g. 95%, the consequent clockwise movement of lever 119 caused by cam 122 is sufficient, via plunger 178 and bellcrank 136, to move the lever 134 away from the valves 115, 116 and thereby avoid any throttling of those valves and consequent reopening of the compressor bleeds. Roller 172 on rod 170 associated with actuator 34, co-operates with the bell-crank 136 to ensure that the fuel regulating means does not allow the engine to operate at the acceleration or deceleration limits prior to opening of the compressor bleeds.

Filed: 1968-06-06
Abstract: 1,199,370. Lubricating. TECUMSEH PRODUCTS CO. 6 June, 1968 [12 July, 1967], No. 26894/68. Heading F2A. [Also in Division F1] A rotatable body, such as a shaft 22 of a motor-compressor unit, has an axial bore 28 through which lubricant is forced, the axial bore having a first discharge port 62 through which lubricant is centrifuged and directed within a predetermined angular range when the body rotates at a first speed, and the axial bore having a second discharge port 60 through which lubricant is also centrifuged when the body rotates at a second speed. The combined discharges of lubricant when the body rotates at the second speed are together directed within the same predetermined angular range as the predetermined angular range through which lubricant from the first discharge port is directed, that is when the body rotates at a first speed. A compressor 20, Fig. 1, and a motor 18 are mounted within a sealed shell 16. The compressor shaft 22 is mounted in bearings 23, 24, has an extension 25 which serves as a shaft for the motor 18, and has a pump 26 mounted at its lower end. The shaft 22 has a concentric bore 28, Fig. 2; an eccentric bore 32, a port 38 and a helical groove 40 for lubricating the bearing 23; a radial port 50, Fig. 3, for lubricating the bearing 24; and a port 46, Fig. 5, for lubricating a piston and cylinder 42, 44, Fig. 1. Excess lubricant, which does not pass through the ports 38, 46 and 50, passes through the bore 32 and through a port 62, Fig. 3, when the shaft is rotating at a first speed or passes through both the port 62 and a port 60, Fig. 2, when the shaft is rotating at a second speed. The arrangement and construction of the ports 60 and 62 ensures that the excess lubricant leaves the shaft 22 in a predetermined direction so that substantially all the excess lubricant contacts the shell 16 and is thereby cooled.

Title: Improvements in or relating to selenium rectifiers
Inventor: GILBERT JOSEPH
IPC: H01L21/10
Filed: 1959-08-07
Abstract: 880,367. Selenium rectifiers. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Aug. 5, 1960 [Aug. 7, 1959], No. 27030/59. Class 37. A method of making a selenium rectifier comprises forming on a base electrode a layer of material which forms a rectifying contact with Se, depositing thereon a first substantially halogen-free layer of vitreous Se, a second halogenated vitreous Se layer, and another electrode, the structure so formed being subjected to heat treatment to convert the vitreous Se to crystalline Se. The base electrode may be of steel, and the layer which forms a rectifying contact with Se may be Sn, Pb, Bi, &c., or may be Cd or a Cd alloy, to which 0.001-0.1% of Tl, In, Sb, As, Bi, or a mixture thereof may be added; a layer of lacquer may be used in producing the rectifying contact. An additional barrier layer of T1, Cd, Se, CdS, In, or a mixture of two or more of these materials, to any of which Se may be added, may be applied to a Cd layer. The first Se layer, which may contain additives such as Sb, As, Bi, S, Te, In may be evaporated on to the unheated base electrode, and a further layer or layers of Se with impurities such as In or Tl may be provided between first and second Se layers. The second Se layer may have a halogen content between 200 and 700 parts per million. An ohmic contact to the Se may be made by deposition of a thin layer of Te, Co, Ni, Fe, or an alloy thereof, to which a relatively thick layer of metal, such as Sn, may be applied, as by spraying. The heat treatment, which may be by progressive stages, is carried out at temperatures between 180‹ C. and the melting point of Se. The rectifier is electroformed in known manner; this may be combined with the heat treatment. As shown, Fig. 1, a base electrode 1 has one face plated, as by electroplating in a cyanide bath, with a layer 2 of Cd. A first Se layer 3 is substantially free of halogen, while a thicker second Se layer 4 has a Cl content of about 300 parts per million. A vaporized film 5 of Te forms the ohmic electrode, to which a layer 6 of Sn is sprayed. Fig. 2 (not shown) is a graph of the voltage-current characteristic of the rectifier.
