Abstract: 640,098. Rotary pumps or engines. MINISTER OF SUPPLY, and NICHOLSON, S. G. Oct. 16, 1947, No. 27691. [Class 110 (ii)] The pump or engine has a number of inner arcuate elements coaxially arranged with respect to the rotor and spaced apart so as to leave a gap between their ends, a stator ring movable in part or wholly positioned between the rotor periphery and the arcuate elements and a number of crossheads attached to the stator ring and slidably mounted between the gapped ends of the elements whereby the gap between the rotor and the ring is adjustable. Figs. 1, 3 show a pump or engine having outwardlysliding radial or curved vanes, or rollers, with a stator made up of two or more segments 26, 27 which are movable through cross-heads 28, 29 to vary the capacity of the working chamber or chambers. In one form diagonal gaps 25a between adjacent ends of segments 26, 27 allows inward movements of the latter. The cross-heads are moved by means of a rocking lever 50 secured to parts 49, 49a which lift one roller 45, and depress the other 44, the rollers being mounted on pins 43 which are guided in slots 47. Fluid is supplied from the working chambers to a cylinder 52 and acts on the underside of a piston 23 to balance the downward force on a roller 45. For a pump rotating in anti-clockwise direction inlet and outlet ports 40, 39 are connected to passages 42, 41 respectively. To give no delivery from the pump, the cross-head 28 is moved to the left in Fig. 1 so that the rotor 32 and segments 26, 27 become concentric. Another chamber 66 contains fluid to the level 61 and some of this may pass into the working chambers through one of the non-return valves 64. Vanes 35, preferably of self-lubricating material, slide in slots 36, the undersides of the slots being vented through bores 38. The segmental ports 26, 27 are narrowed in the vicinities of the ports 39, 40. End ports 16, 17 of the casing may be of light alloy, and two side plates 18, 19 of hardened steel. Bolts 31 pass through ports 16, 17 and plates 18, 19 and also through clearance holes 31a. The rotor shaft 33 rotates in anti-friction bearings 34, and has end seals 67. The inner end radii of the ports 26, 27 are equal to the radius of the rotor so that when the ports are closest together effective sealing is provided. A sealing plate or cover 59 moves with the lever 50 when the latter is rocked over. In a modified arrangement, Fig. 10 (not shown), the stator comprises one rigid element and the balance pistons 23, 24 may be dispensed with. Curved vanes or rollers may be used instead of the straight vanes.

Title: Process for producing pure iron powder and product thereof
IPC: C21B15/00
Filed: 1966-06-23
Abstract: 1,137,525. Iron powder; iron oxide. CENTRO SPERIMENTALE METALLURGICO S.p.A. 23 June, 1966 [23 June, 1965], No. 28156/66. Heading C1A. Crystalline, heptahydrated iron sulphate is dried, and its grain size increased, in a fluidized bed reactor, dehydrated and dissociated by heating whilst maintaining the grain size, and then heated in a fluidized bed reactor to 900 to 1200‹ C. prior to reduction, preferably also in a fluidized bed reactor, with reducing gases at 800 to 1200‹ C. In a modification the reduction is carried out by using a solid reducing material, such as carbon black, charcoal, graphite, or mineral oil coke, instead of the reducing gas. The grain size may be increased to 0À2 to 1À0 mm. by drying at 60 to 100‹ C. and almost pure hematite is obtained after dehydrating at 200-300‹ C. and dissociating at about 800‹ C. in a fluidized bed reactor. The iron powder produced by reduction may be heated to 1000 to 1100‹ C. for 10 to 30 minutes in an inert or reducing atmosphere to reduce its pyrophoricity and may be subsequently subjected to crushing and screening operations. The reducing gas may travel countercurrent to the ferrous compounds in which case it is heated to the temperature required for the reduction by heat exchange with the hot iron powder and the iron oxide is heated to the temperature required for the reduction by combustion of the spent reducing gas. The spent reducing gas may however be collected after the reduction stage and enriched to make it reducing and recycled. The iron sulphate may be suitably obtained by crystallization of exhausted pickling baths for steel sheets.

Patent GB-680636-A (GB)
Title: Improvements in or relating to machines for treating hosiery or other articles of knitted or textile fabric
IPC: D06C5/00
Filed: 1949-11-03
Abstract: A machine for pre-boarding, drying or analogously treating hosiery and other articles of knitted or textile fabric, comprises a rotary table carrying an upstanding wall and means for supporting at least two sets of forms on which articles to be treated can be drawn, with one at least of these sets on each side of the wall, a heating chamber normally open on one side but adapted to be closed by the wall, and means for bringing together or separating the wall and the chamber.  The machine may comprise a base 1 carrying a frame 2 supporting a pair of <PICT:0680636/IV (c)/1> rails 19 on which the heating chamber 3 may be moved.  The rails 19 may be brought successively into register with pairs of rails 20, 21 on either side of the wall 13, mounted on the rotary table 9 which is supported on a spider 10, and is manually rotatable about a bearing 8, by means of handles 14.  Hose forms 18 are individually pivoted on spindles 16 carried by pairs of brackets 15 on either side of the wall 13.  The rails 19 and 20 or 21 being brought into alignment, an abutment on the table 9 closes a switch on the frame 2, thereby actuating a solenoid which locks the table against further rotation and starts a timing gear 43.  This starts an electric motor 27 and causes the chamber 3 to be moved by chain connections 28, 38 and 31, 33 until it contacts the wall 13, when a micro-switch 51 is operated by a projection 50 on the wall, and causes the timing gear 43 to break the supply circuit of the motor 27 and to apply an electromagnetic brake thereon.  A flange 53 on the edge of the chamber closes against a rubber sealing strip on the wall 13, and the chamber is locked in position by a fastening means 57 having a cylinder connected to the inside of the chamber, and a plunger which is integral with a piston moving in the cylinder, and is forced into a boss 79 when the internal pressure is raised.  A valve controlled by the timing unit 43 now admits steam to the chamber 3, for a predetermined period, after which the steam is cut off and a vacuum applied.  When the pressure has fallen sufficiently, a pressure switch communicating with the interior of the chamber acts to reverse the direction of the motor 27, which is next started by the timing device 43, to retract the chamber 3, and is then arrested, the solenoid locking the table 9 being de-energized, to permit rotation of the latter.  The apparatus may be adapted for drying hose or other articles, with or without a previous plasticizing operation, by providing the chamber with a supply of hot air; radiant heat may also be used.

Title: Improvements relating to automatic control of railway car retarders
IPC: B61L17/02
Filed: 1954-10-01
Abstract: 746,735. Railway car retarder brakes. GENERAL RAILWAY SIGNAL CO. Oct. 1, 1954 [Oct. 1, 1953], No. 28376/54. Class 103 (1). In a track retarder control mechanism for railway sorting yards using car retarders such as that described in Specification 303,446, [Class 103 (i)], wherein a car or cut of cars passing from the single approach track to any of a number of classification tracks 1-12 will pass through successive retarders such as Nos. 1-5, as shown in Fig. 1, the weight registered by the cars in passing over the weighting rail WR is successively passed in advance to weight storage means for successive retarders along the route, each retarder being arranged to determine in dependence on the weight registration stored thereby the extent of the braking to be applied by the appertaining retarder. The retarder control system includes the use of radar speed detecting apparatus, which actuates speed registration means for use in conjunction with the weight storage means for determining the extent of braking to be applied, and provision is also made for correcting for the curvature effects in different tracks and for cancellation of weight storages should there be insufficient spacing between the cars. As shown in Fig. 3A, the weighing rail WR operates a shaft 20 which closes contacts between finger 30 and fingers 31, 37 or 39 according to whether the car passing is of light, medium, or heavy weight classification, thus actuating weight relays 1LW, 1MW, and 1HW. Figs. 3B, 3C and 3D show part of the circuits by means of which the weight registrations are passed to relays 2W1, 2W2, 3W1-1, 3W1-2, 3W2-1, 3W2-2, 8W1, 8W2, 10W1-1 and 10W2-1 for storing weight information that is transferred from one storage unit to another as each associated car progresses, such transfers being governed by the transfer relays 2TN, 2TNP, 3TN-1, 3TN-2, 3TNP, 8TN, 10TN-1. Figs. 7 and 8 illustrate schematically by block diagram the manner in which speed control and other relays 4CK, 4XR, 4TN2, 4TNP, 5CK, 5XR, 5TN, 5TNP are governed by speed responsive apparatus associated with car retarders Nos. 4 and 5. Such block diagrams include units providing correction on account of variations in the track resistance due to curves. The high-pass electronic filters control relays 4LS, 4MS, 4HS, 5LS, 5MS and 5HS for indicating relative low, medium and high speeds of cars progressing within a speed range requiring retardation. The block diagrams also include the radar speed responsive apparatus. Fig. 11 shows a block diagram illustrating the manner in which correction is made for curves in the track according to the destination of a car. Fig. 12A illustrates by track diagram the progress of a car from the hump to classification tracks 1 and 2 in Figs. 1 and 13A is a sequence chart showing the mode of operation of the control apparatus for respective stages of progress of a car towards the tracks. U.S.A. Specifications 2,038,112 and 2,194,353 also are referred to.

Title: Improvements in and relating to the protection of three-phase and polyphase networksfrom disturbances caused by short-circuits due to arcing
IPC: H02H3/06
Filed: 1939-10-21
Abstract: 538,265. Fluid-pressure servomotor control systems. AKT-GES. BROWN BOVERI & CIE. Oct. 21, 1939, No. 28417. Convention date, Nov. 17, 1938. Addition to 522,206, [Group XXXVII]. [Class 135] [Also in Group XXXVII] The invention of the parent Specification is modified in that a longer pause between disconnection and reconnection of one conductor is allowed in the case of a single-phase fault than in the case of an interphase fault, to allow for complete de-ionization of the arc on the line, the pause being controlled by an additional timeelement controlled so as to be responsive only to a single-phase fault. The time-element may be a clockwork mechanism or mechanical or electrical damping, and the control may be effected, as shown, pneumatically, or electropneumatically, by distant control. When an earth fault occurs on, say, line l, relay r 1  energizes a relay s 1  which opens a valve V1 and admits air-pressure from reservoir d to move piston K to the left, open main valve HI, and admit air to the cylinder a1 to open line switch L1. Air at the same time passes through an adjustable throttle valve V2 into a timing cylinder Z1 which, after a delay, opens valve V3 and restores piston K. With a fault on all the lines l 1  - l 3 S, relays R1 - R3 are all energized by relays r1 - r3 and energize a relay R11, which opens valve V4 and, through the medium of shaft W, opens all the valves HI - H3. When relay R11 is de-energized, it opens the piston k to atmosphere and valves H1 - H3 reclose at once, the timing members ZI - Z3 being inoperative.
