Title: Improvements in or relating to the surface conditioning of metal bodies by electron beams
IPC: H01J37/305
Filed: 1966-12-13
Abstract: 1,148,683. Removing metal by electron beams. AIR REDUCTION CO. Inc. 13 Dec., 1966 [10 Jan., 1966], No. 55796/66. Heading B3V. [Also in Division H1] Surface or sub-surface defects are removed from a solid metal body 21 by melting the surface to a predetermined depth using an electron beam, and then allowing it to solidify in a controlled manner. A workpiece 21 such as a slab, ingot, or continuous casting, is moved, preferably continuously on a continuous roller conveyer 21, through a vacuum lock chamber 13 into an evacuated chamber 12 connected at 12a to a high vacuum source, where its upper surface is melted to a predetermined depth by an electron gun 18 and then allowed to solidify from the inside under control of a lowerpowered electron gun 18a. The workpiece is then reversed and its other surface is conditioned by further electron guns 19, 19a. Finally the workpiece passes to atmosphere through another vacuum lock chamber 14. Alternatively the workpiece may be passed in and out through the same vacuum lock. Each electron gun assembly 18, Fig. 3, comprises a pair of guns 22, 23 whose beams are caused to scan the workpiece 21 between A and B. The beam produced by filament 25 and electrode 26 is first directed upwardly to prevent accumulation of condensed metal vapours thereon. A magnetic field produced by electromagnets such as 28 bends the beam through 180 degrees and further electromagnets, such as 34, supplied with alternating current, produce the scanning movement. Cooled side rails 35 are used to confine the molten surface metal and extrapower may be supplied or an additional electrode gun used to compensate for any heat loss; alternatively the scanning may be restricted to prevent melting of the side edges. Where cast slabs are produced under vacuum in electrode beam furnaces, the surface conditioning may be performed before removal of the cast slab from its vacuum system. References are made to the treatment of titanium, zirconium, iron, bronze alloys of tantalum, columbium, molybdenum; examples are given of the power used when conditioning nickel and cobalt base alloys, columbium and tantalum; specific examples are given for conditioning.

Abstract: 1,152,360. Automatic tuning of amplifiers; testing radio receivers. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 12 Dec., 1967 [12 Dec., 1966], No. 56476/67. Headings H3A and H4L. The tuned circuits 11-14 of an I.F. amplifier 5 are aligned in response to the output signals produced by the amplifier when test signals are applied to its input. In Fig. 1 a signal generator 30 produces outputs at, for example, ten frequencies f 1  to   f n  spaced through the pass-band of the amplifier, the frequencies being fed sequentially via switching means 31 to the input terminal 20, and corresponding outputs derived from a detector 21 are fed via a second switching means 33 to storage means 34. The signals stored in the cells H1-Hn of the storage means are coupled directly and/or through an inverter P1-Pn to a combining circuit 37, which may be a resistance matrix (Fig. 6, not shown) and which provides four output signals for driving the motors 48-51 which adjust the tuning means of the tuned circuits 11-14 to produce a desired amplitude/frequency characteristic determined by the combining circuit 37.

Title: Torque exchanging coupling
IPC: F16D43/21
Filed: 1971-12-06
Abstract: 1349267 Friction clutches BENDIX CORP 6 Dec 1971 [28 Dec 1970] 56566/71 Heading F2C A friction clutch which disengages on overrun comprises a driving clutch plate 13 splined to the clutch housing formed by flanges 5 and 6 (around which is the drive gear 7) and biased to a disengaged position by springs 14 and 39, and two presser plates 16 and 17 mounted on carriers 31 and 32, the right carrier 32 being axially movable on helical splines 30 on the output shaft 18. This carrier 32 is axially movable by being rotated by a clutch actuating sleeve 46 through pins 45 which protrude through slots in the shaft 18. A Belleville spring 35 acts against teeth 34 of the left presser plate to hold it clear of its carrier 31. In operation a control rod 55 serves to move the actuating sleeve 46 leftward which, due to the interaction of helical surfaces on teeth 47 of the sleeve with teeth 49 of a member secured to shaft 18, causes rotation, and axial movement of the carrier 32 and so brings plate 17 into contact with driving plate 13. The resultant interaction therebetween moves the carrier 32 yet further leftwards so that presser plate 16 is contacted. Due to the configuration of teeth 47 and 49 (Fig. 3, not shown) the leftward movement of carrier 32 is limited so that presser plate 16 is not held against its carrier, but only against spring 35 so that this spring determines the torque transmitted by the clutch when it is first engaged to prevent stalling of the prime mover. When synchronization is complete, output shaft at speed of input gear ring 7, the control rod is moved to the right which moves the actuator 46 and so disengages teeth 47 and 49 which allows the carrier 32 to move further to the left, hold plate 16 against its carrier, and increase the torque capacity of the clutch. If overrunning occurs the helical splines 30, aided by springs 35 and 14, serve to disengage the clutch. The clutch can be between the gas turbine engine and rotor of a helicopter.

An MHD generator comprises a conductive gas, vapour or liquid caused to rotate within a magnetic field in a vortex chamber by a propellant fluid. The conductive medium may be a liquid sodium-potassium mixture and the propellant may be helium or sodium vapour. The vortex chamber 10 disclosed is formed by a conductive jacket 11 and insulating base and cover plates 10, 13 respectively. The jacket 11 forms one electrode and a central post 21 the other. The propellant is directed tangentially into the working medium through one or more pipes 14. The propellant leaves the chamber through an aperture in plate 13. The magnetic field is created by superconducting coils. The voltage produced may be varied by changing the supply of propellant using valves 30, 31, Fig. 1 (not shown), or by varying the speed of the propellant. A poly phase generator may be obtained, Figs. 3, 4 (not shown), by arranging two or more vortex chambers such that they have a common supply of propellant and directing the propellant alternately to the different chambers. The propellant outlet may be a duct having oppositely disposed conductive sides 111, 121, Figs. 5, 6 (not shown), connected to a source of voltage so as to create a transverse field in the duct producing a downwards force on any working medium in the duct and so serving to retain the working medium in the vortex chamber.

In the illustrated embodiment the contact 16 is a disc which, together with the adjacent part of the diaphragm 14, is slidable along a spindle 13 fixed in the body 1 and mounting the spring 17.

In alternative methods of producing resinfibre composites a film of the ethylene copolymer is melt coated on to the fibrous material; powdered copolymer is sprinkled over the fibrous material and radiant heat is applied to fuse the copolymer; finally powdered copolymer may be dispersed in the uncross-linked thermosetting resin.
