IPC: B21B39/32
Filed: 1946-12-18
Abstract: 626,356. Rollerway conveyers. ALUMINUM CO. OF AMERICA. Dec. 18, 1946, No. 37253. Convention date, Jan. 30, 1940. [Class 78 (i)] A work handling apparatus for use with a scalping machine of the type disclosed in U.S.A. Specification 2,326,847 comprises a normally horizontal conveyer table which is adapted to be inclined in either direction for delivery of workpieces there along and has component parts which are adapted to be moved in opposite directions with respect to each other to and from a co-operative, off-vertical position for inverting a workpiece deposited on the conveyer table by a co-operating work turning member or arm angularly movable with respect to the table. Ingots 12 are transferred from a tilting work table 15 to a scalping machine and later returned to the table for reversal by arms 25 which are pivoted about a shaft 26 by a piston and cylinder device 34. Mounted on these arms are a series of rollers 27, 28, 29, 30, arranged so that when the arms are vertical the ingot is engaged by the roller 28 which is adjustable and serves to locate the ingoton blocks 56 which are mounted on retractable fingers 36 controlled by a piston and cylinder device 40. The reversing arms 42 and 43 have rollers 16 on their upper surfaces and, when horizontal, form the surface of the table 15 the slope of which is controlled by a piston and cylinder device 22. Shafts 44 and 45 which are operatively secured to said reversing arms, are rotated by a piston and cylinder device 47 through a mechanism comprising a piston rod 49 a lever 50, a crank 51 a link 52, a crank 53 and gear segments 54 and 55, the arrangement being such that the two arms are rotated to a position in which they are parallel and in an off-vertical position so transferring an ingot from one arm to the other so that when the arms have been lowered the ingot has been turned over. Fully machined ingots are tipped from the table 15 on to a fixed receiving platform 5 from which they are removed by known means. The inclination of the arms 25 is controlled by members 66 which abut against stops 65 which are adjustable by means of gearing operated by a handwheel 67.

Title: Improvements in or relating to electro-pneumatic brake systems for rail vehicles
IPC: B60T13/68
Filed: 1960-10-31
Abstract: 904,355. Fluid-pressure brakes. KNORRBREMSE G.m.b.H. Oct. 31, 1960 [Nov. 6, 1959], No. 37333/60. Class 103 (1). An electro-pneumatic brake system for rail vehicles is of the kind comprising a manuallyoperated pneumatic pressure regulator 5 whose regulated pressure is directed to a cylinder 9 containing a double piston 17, 27 for setting the switching position of an electric switch 13, and also to a brake valve 53 and magnetic release valve 55 controlled by the electric switch and arranged respectively for filling a brake cylinder 63 from a compressed-air source and venting it to atmosphere, the arrangement being such that the brake cylinder pressure acts on the double piston 17, 27 for resetting the brake system wherein the electric switch has at or adjacent the ends of a switch arm 33 contacts 35, 37 between which are a fixed pivot 39 and a movable pivot 31 which is movable by the double piston to operate the brake system. In operation, compressed air from a supply pipe 1 charges cylinder spaces 9 and 19 and a reservoir 71 through the regulator 5, and when braking is required the pressure in a pipe 7 is reduced by movement of a handle 3 of the regulator. Since the pressure in the space 9 falls but that in space 19 does not due to a non-return valve 21, the piston 17, 27 moves to the right and rotates the arm 33 about the pivot 39 to close the contacts 35. This closes a circuit including a solenoid 51, and a shut-off valve 67 of the valve 55 closes off the brake cylinder 63 from an atmospheric vent 65. Further movement of the pivot 31 inwardly closes the contacts 37 and a solenoid 49 causes the valve 61 of the braking valve 53 to open and admit air from the brake pipe 1 to the brake cylinder 63. At the same time this air enters a space 29 and moves the piston 17, 27 to the left when the pressure is greater than the value of the initial fall in pressure in the space 9. The contact 37 is broken and the valve 61 therefore closed, giving a brake-holding position. For brake-release the pressure in the pipe 7 is increased by the regulator, the piston 17, 27 moves to the left and the contact 35 is broken to open the valve 67 and hence vent the brake cylinder to atmosphere. In a modification, the regulator 5 may also control the pressure level in a main air pipe which serves to control a brake control valve connected through a double non-return valve to the brake cylinder 63. The actuating device 11 may be connected to a pressure regulator for directly actuating compressed-air brakes and also other magnetic means for controlling and venting brake cylinders may be connected to the conductors 57 and 59, using relays if necessary.

Title: Improvements in or relating to Systems for the Control of Gas Flow Ratios.
Inventor: LITTLER ROY MARSHALL
IPC: G05D11/13
Filed: 1965-09-01
Abstract: 1,173,591. Automatic flow ratio control. HAWKER SIDDELEY DYNAMICS Ltd. Dec. 1, 1966 [Sept. 1, 1965], No.37362/65. Heading G3R. In a system for automatically controlling the air/fuel ratio of a gas engine, differential pressure devices responsive to the rates of flow of air and fuel act on an adjustably pivoted lever associated with an electromagnetic pick-off controlling the flow of air. As described, variations in the rates of flow of air and gas to a spark ignition gas engine are detected by differential pressure diaphragms associated with restrictions in the respective supply conduits. The diaphragms exert forces in opposite directions on a pivoted lever which influences an E-type pick-off controlling a two-phase servomotor through a push-pull transistor amplifier. The servomotor, which is supplied from a Scott-connected transformer, adjusts, through reduction gearing, an air valve associated with a turbo-charger by-pass so that the air/gas ratio is maintained constant at a valve determined by the setting of adjustable pivot points of the lever. Springs and/or a dashpot are provided to damp movements of the lever.

Abstract: 939,045. Electronic calculating apparatus. GENERAL PRECISION Inc. Oct. 30, 1961, No. 38777/61. Class 106 (1). Auxiliary equipment designed for use with a general-purpose digital computer to enable " real time " type calculations, especially those involved in missile guidance, to be carried out comprises a track XO on the magnetic drum store 10 of the main computer (Fig. 1) for recording increments in certain variables which are periodically added in to up-date the values of these variables recorded in a second track. In addition the variables may be integrated with respect to time, and provision is made for outward transmission of the data, and for certain analogue-digital calculations. A crystalcontrolled oscillator is used to provide timing pulses of 800 and 200 sec. necessary for the integration &c. so that the drum need not be run synchronously. Fig. 2 shows the make-up of a word in the XO register, having six bits allocated to represent accumulated increments in each of the velocity components along rectangular axes #X, #Y, #Z and further bit positions for time increments based on the oscillator pulses. Lines A, B, C, D associated with spaced read heads on the XO track enable #X &c. to be read synchronously with separate words on the YO track containing X, Y, &c. so that the increments may be added in and the up-dated values re-written by 38 in successive word times. This is referred to as " phase 1 " operation. Phases 2 and 3 are utilized for integration, e.g. of the numbers representing X, Y, &c. with respect in time, pulses #t 200  occurring at 200 sec. being utilized to control the adding in of the appropriate word (X, Y, &c.) in YO to the contents of an X, Y, &c. word also in YO and re-written by 38 in its up-dated form; phases 2 and 3 are used for single- and doublelength word operations respectively. Phase 4 uses a shift technique to read out the bits of a selected word in YO in succession to a data transmission unit. Other phases are used for entry of data via analogue-digital converters, re-circulation of data, counting down of functions, and carry operations in doublelength words. Logical circuits and their equations for entry of data from an inertial platform, of word counters and incremental adder/subtractors are given.

Abstract: 1437617 Gas turbine rotor blades - cooling GENERAL ELECTRIC CO 16 Aug 1973 [1 Sept 1972] 38822/73 Heading FIT The invention relates to a gas turbine rotor and blade assembly in which the blades are formed with passages for flow of liquid coolant, means being provided for discharge of the coolant from the blades whereby it may impart a useful torque on the blades. The blade shown in Fig. 1 comprises a core portion 12 and an outer skin 11, the core being formed with a series of longitudinallyextending grooves 13a whereby a series of coolant passages 13 are formed between the core and the skin. Each blade carries a blade platform at its inner end and a shroud portion 16 at its outer end. Manifold grooves 17, 17a are formed adjacent the shroud 16 and passages 21, 21a extend from the manifolds to a chamber 22 formed in the shroud, a convergent-divergent discharge nozzle 23, 24, 26 extending from the chamber. The discharge nozzle is aligned with an opening 18 formed in the stator casing 19. Thus coolant liquid supplied at the inner ends of the passages 13 flows radially outwardly therethrough, thence through the manifolds 17, 17a to discharge through the nozzle 26 into the discharge passage 18, the liquid exerting tangential thrust, also radial inward force on the blade. The shroud is formed with seal ribs 28, 29 and coolant liquid discharging from the passages 13b, 13c adjacent the leading and trailing edges of the blade acts as sealing fluid as it discharges past the seal ribs. The blade root comprises a series of tines 31 which are received in circumferential grooves 34 formed at the periphery of the rotor disc 33, the disc being formed with inwardly facing annular grooves 41, 41a to which coolant liquid is supplied and from which it passes through bores 43, 43a to passages 38 formed on the inner surface of the platform 37, the liquid flowing from the passages 38 to the blade passages 13. In Fig. 4 no blade shroud is fitted, there being manifold grooves 51, 5 1a formed adjacent the blade tip, the coolant passages 13 opening into the grooves; the groove 5 1a connects with the groove 51 at 52 and the groove 51 then opens to a convergent-divergent coolant discharge nozzle 53 which opens at the blade trailing edge. Coolant discharges from the nozzle to a passage 54 formed in the stator casing, the discharge comprising tangential and axial components.
