Filed: 1970-12-21
Abstract: 1339550 Multiple exposure apparatus XEROX CORP 21 Dec 1970 [22,Dec 1969] 60518/70 Heading G2A Imaging apparatus, as shown a photoelectrophoretic copier, comprises a rotatable drum 36 for an original 34; an injecting electrode 1 in the form of a rotatable cylinder; a plurality of optical means, as shown two, each of which images a separate area of the drum 36 on to separate area 10, 24 of the electrode 1; and means aligning the optical means so that the same position of the original appearing successively at each separate area of the drum 36 is imaged in superposition with itself at each separate area of the electrode 1. The original 34, illuminated by lights 40-43, passes through the object planes of lenses of the optical means, as shown the lenses 38, 39. Plane mirrors 50, 51 and roof mirrors 52, 53 are utilized so that a first area of the original is imaged on to the electrode 1 at the area 10 by the lens 39 and mirrors 53, 51, and the first area is then imaged by the lens 38 and mirrors 52, 50 on to the same portion of the rotating electrode 1 at the area 24 in superposition with the first image thereof. The lens 25, 38, 39 are mounted so that their axes 48, 49 do not coincide with the prinicipal rays 45, 46 of the respective optical means. In another arrangement Fig. 2, (not shown) the lenses (74, 76) are parallel, but still their axes do not coincide with the principal rays, one lens (74) has a plane mirror (61) before it in the ray path, and a roof mirror (63) after it while the other lens (76) has a roof mirror (60) before it and a plane mirror (62) after it. The distances between the mirrors and the focal planes of the arrangement may be varied by means of hanging jacks (68- 71), so as to compensate for deviations in the super positioning of the images of the same area of an original. This superpositioning enhances the final image.

Patent GB-673496-A (GB)
Abstract: 673,496. Dynamo electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. May 16, 1950 [May 25, 1949], No. 12204/50. Classes 35 and 38 (ii). Commutation is effected in electric motors and generators without the use of contacts by means of the Hall effect. Flux from a permanent magnet rotor is passed through a conducting plate, which may be of germanium or bismuth and is referred to as a Hall plate, whilst an exciting current is passed laterally through it to produce an E.M.F. between its ends. In its simplest form, Fig. 1, a generator having a permanent magnet rotor 1 and stator windings 3, 4, has the Hall plates 5, 6 extending across the stator pole faces so that the working flux passes through them. The Hall plates have terminals at each of their four edges and the lateral terminals 7, 8 are fed by the stator coils. The effect of the simultaneously-reversing current and flux passing through the plates is to produce a Hall voltage between its ends which are connected at terminals 9, 10 to the D.C. output circuit. In the D.C. motor shown in Fig. 3, Hall plates 17, 18 are energized by current from a source 19 and are cut by flux from horse-shoe magnets 14, 15 revolving on shaft 13. The Hall voltages are connected, through a switch 20R for reversing the rotation of the motor, to the coils of a stationary winding 20 which drives a magnetic rotor 16 also mounted on the shaft 13, the Hall plates effecting commutation. In a modification, the functions of the driving magnet and commutating magnets are performed by a single magnet, the Hallplates being placed in quadrature with the driving coils. In a further modification a series of Hall plates, connected to driving coils, are spaced around a magnetic rotor having one or two magnetic discs so that a smooth torque is produced. The Hall plate voltage may be amplified before feeding the driving coils, if required. This is shown, in Fig. 6, for a servomotor in which the Hall, plates 27 are fed with an A.C. error voltage at 28, the output of the plates controlling the supply to the driving coils 32 from A.C. source 29 by means of valves 31, the magnet 26 and Hall plates 27 acting as a commutating device as before. The supply 29 and error signal appearing at 28 are derived from a common A.C. source and the phase and magnitude of the signal voltage controls the current in coils 32 and thus the motor speed. The device is shown as operating a recorder 33 and indicator 34 for a thermocouple 35 whose voltage is compared with that of a standard cell 37, the balance being maintained by a potentiometer 36 driven by the motor, and the error signal being converted to A.C. at 38 for feeding the winding 28.through amplifier 39.
Patent GB-2002871-A (GB)
Title: Improvements in and relating to flexible ducting
IPC: F16L3/015
Filed: 1978-08-25
Abstract: A flexible ducting element is described which can form a separate unit adapted to be secured to another length of ducting or may comprise an integral section at one end of an overall length of ducting. The ducting is formed from a flexible sleeve 28 and includes a flared insert 30 on at one end through which air is drawn and a supporting ring 32 at its other end. The flexible sleeve is formed from a plastics or similar sheet material having bonded thereto a helical spring. The sleeve will normally occupy an in-line configuration but can be deflected relative to this in-line condition. The invention provides for one or more stay-put springs or similar devices (58) to be secured between the elements 30 and 32 either internally or externally of the sleeve 34 so as to cause the flexible ducting to occupy a deflected position to one side or the other. A complete fume extraction system is described which may be portable and includes support arms for locating the flexible hose/ducting 28 at any convenient point within a working zone or may be wall mounted.   Air filtering such as electrostatic and/or carbon is incorporated into the extraction equipment to allow cleaned air to be recirculated into the working environment if desired. <IMAGE>

Title: Fabric Decoration Apparatus and Method
IPC: D04H18/02
Filed: 1978-12-15
Abstract: Decorated fabrics comprise a decorative pattern in the form of at least one fibrous strand consolidated into the fabric in a predetermined area by needle punching. Apparatus for producing fabrics decorated in this way comprises a reciprocating array of needles (14), means for advancing a fabric in a controlled manner (32) and one or more guides or feeders (20) for supplying the decorative strand or strands (22) to the fabric in the working zone (26) where the needles operate. The array of needles is preferably of restricted width comparable to that of the strands being applied and the apparatus is most conveniently provided as a modification of a conventional sewing machine. The strands and perhaps also the basic fabric preferably comprises wool fibres and the decorated fabric may be milled to further consolidate the decoration. The invention enables fibrous decoration to be applied at a late stage in fabric production or even to finished garments. <IMAGE>

Title: Adjusting leak paths in telescopic hydraulic shock absorbers
IPC: F16F9/46
Filed: 1979-01-24
Abstract: Relative rotation of a cam 48 causes it to move axially relative to the remainder of the piston assembly in order to vary the cross-sectional area of a rebound leak path (58,60,62) provided across the piston. The axial displacement of the cam member 48 may if desired be additionally used to vary the biasing force of a spring 44 acting on valve element 40. To adjust the damping, the cam 48 is locked to the cylinder and the piston rod is rotated, causing lugs 50 on the piston nut 26 to engage a different pair of surfaces on the cam 48. <IMAGE>

Title: Arc butt welding of porous metal sheet
IPC: B23K9/23
Filed: 1979-03-19
Abstract: A porous metal sheet, e.g. for a gas turbine combustion chamber, made by bonding two sheets face to face after forming intersecting channels 18, 20 and holes (22), 24 in them, is then bent and its edges 26, 28 joined by arc welding.
