IPC: C21D1/10
Filed: 1970-04-16
Abstract: 1297067 Heat-treatment by induction AEG-ELOTHERM GmbH 16 April 1970 [18 Dec 1969] 18277/70 Heading C7N [Also in Division H5] In induction heating apparatus of the type comprising an inductor 6 having two conductors 7 extending along a workpiece 1 and inter-connected to form a loop 8, the inductor 6 being supplied with medium frequency A.C. through feeders 9, a second current input is provided through connections 12 on loop 8 via feeders 14 and switching means, Fig.2 (not shown), allows the inductor 6 to be supplied with current through both pairs of feeders 9, 14, simultaneously or only through one pair. The temperature distribution along the workpiece is thereby optimized. A supplementary loop 15 pre-heats the flange 5 of the workpiece. In a further embodiment, Fig. 5, Fig. 4 (not shown), where shaft 29 of the workpiece merges into a bearing 31 of greater diameter and then a flange 30, the loop 35 in the region of the fillet 32 is spaced from the supplementary loop 40 as shown. The workpiece 1 is held between centres 2 of spiders 23 for rotation between indexed positions 25, (a body station), 26, (a heating station by inductor 6), and 28, (a quenching and unloading station). Reference is made to heating workpieces of substantially constant diameter such-that the heat penetrates to different depths in different zones. When supplied via two inputs the heating current in loop 8 is higher and in the conductors 7 lower than when current is supplied through only one imput. Similarly, the heating current in loop 35 is higher and in the conductors 34, Fig. 4, (not shown), lower when supplied via two inputs.

Preferably the treatment is in acid aqueous solution e.g. pH 3 to 6 at temperatures above 60‹C especially 95‹C to the boiling point. The fibres are then dyed, padded or printed with e.g. acid milling or premetallised dyes. Glyoxal and sodium pyrosulphite may be used to produce the glyoxalsodium bisulphite in the pretreatment process.

Title: Fluid pressure operable brake control valve apparatus
IPC: B60T17/20
Filed: 1970-06-09
Abstract: 1306708 Brake control valve apparatus WESTINGHOUSE BRAKE & SIGNAL CO Ltd 19 May 1971 [9 June 1970] 27923/70 Heading F2F A fluid pressure operable brake control valve apparatus for controlling in response to brake pipe pressure the supply of fluid under pressure into an out of a brake cylinder comprises a pressure responsive member 40 separating a chamber p at brake pipe BP pressure from a chamber q at a quick action chamber QAC reference chamber pressure. A choke arrangement 62, 63 is connected in series between the chambers p, q and is so dimensioned as to render the member movably responsive only to at least a predetermined change of brakepipe pressure in a given time to open a brake cylinder valve 50 to provide in operation, a communication between a fluid pressure reservoir, e.g. an emergency reservoir, and a brake cylinder. Movement of the member in the brake actuating direction effects the closure of a choke varying valve 58 whereby the choke resistance between the two chambers is increased. In the construction shown the choke arrangement consists of two chokes 62, 63 one 62 of which is by-passed by the choke varying valve 58 during the initial movement of the member 40. Movement of the member 40 from its rest position also operates a valve 44 which vents the brake pipe to atmosphere. On release of the brakes the member 40 moves past its rest position against a spring 65 thereby opening an emergency accelerated release valve 47 to connect the brake cylinder and an auxiliary reservoir to the brake pipe. The valve 47 in conjunction with its spring 48 operates as a check valve such that it recloses when the auxiliary reservoir and brake cylinder pressures have attained values within approximately 10 p.s.i. of the brake pipe pressure. A pressure responsive member controlled emergency inshot valve 53 is provided which remains-open to allow a rapid build up of pressure in the brake cylinder up to a predetermined pressure whence the valve closes further buildup of pressure in the brake cylinder being then restricted by a throttle 56. The service portion of the apparatus is similar to that disclosed in Specifications 1,280,263 and 1,287,972 and comprises a pressure responsive member 1 which controls a brake cylinder inlet valve 4, a brake cylinder exhaust valve 5, an auxiliary reservoir charging valve 6 and an associated emergency reservoir valve 7. The central stem 2 of the pressure responsive member is coupled to a quick service and inlet exhaust valve assembly 9. A brake cylinder inshot valve 20, a brake cylinder maintaining valve 24 and a retarded recharge valve 30 are also provided.

Patent GB-1320345-A (GB)
Title: Centrifugal separators
IPC: B04B11/04
Filed: 1970-05-13
Abstract: 1320345 Centrifugal separators JACO ENG DEVELOPMENTS CO Ltd 9 Aug 1971 [13 May 1970] 23066/70 Heading B2P Solids are separated from a liquid by passing a mixture thereof through a rotating centrifuge drum to deposit the solids on the drum wall, and intermittently reversing the direction of rotation of the drum to open one or more valves controlling the opening or closing of one or more apertures in the drum wall and eject the solids through the aperture or apertures. A pair of centrifuges may be mounted side by side to treat dirty water pumped to them from a pit or tank to which the water is delivered from a motor vehicle chassis cleaning apparatus. Each separator, Fig. 2, comprises a drum 20 mounted fast with a shaft 22 driven by a reversible motor 24. Alternatively, the shaft may be driven by a chain transmission with a torque limiting clutch in the transmission. Dirty water is delivered to one end of the drum through a manifold 30 and an inlet aperture 28. A discharge aperture 34 at the opposite end opens into a collector 60 which has an outlet spout 62 and is clamped to a ram of a fluid pressure cylinder 64 so as to be movable between the full line and the chain dot line positions to move the outlet spout 62 from a position above a clean water tank 72 to a position above a dirt tank 74. A series of solids discharge ports are formed in the drum wall in the form of circumferentially and axially spaced slots 40. A closure valve associated with each slot comprises a plate 42 backed by a panel 44 of resilient sealing material which extends around the periphery of the slot and is secured to the drum adjacent one lateral edge of the slot to form a hinge for a valve. A plate 46 secured to the panel 44 has an inwardly directed scoop portion 48. A tension spring 54 secured between the scoop 48 and a plate 50 clamped to the portion of the panel fixed to the drum tends to move the valve to the open position shown in Fig. 4. A stop is provided at 52. In operation, when the drum is rotated in the direction of the arrow A, dirty water is introduced into the drum and, due to the rotation of the latter, is swirled and thrown outwardly by centrifugal force so as to move the valve plates 42 to the closed position of Fig. 5. Dirt is deposited on the wall and clean water delivered to the tank 72. After the dirt has accumulated on the wall, the drum is stopped and rotated in the reverse direction and the collector 60 is moved by the cylinder 64 to the chain dot position shown in Fig. 2. The dirty water supply to the drum is continued during these operations. The water swirling in the tank as a result of the contrarotation then engages the scoops 48 to assist the opening of the valves by the springs 54. The swirling water then discharges through the slots and washes the deposited dirt from the drum wall into the dirt tank 74.
