Abstract: 1320694 Electron microscopes ASSOCIATED ELECTRICAL INDUSTRIES Ltd 17 Sept 1970 [17 June 1969] 30657/69 Heading H1D An electron microscope includes stores 8 and 9, Fig. 3, for unexposed and exposed photographic plates separated by a wall 10 from the microscope chamber, means for feeding the plates to and from an operative position via an aperture 11 in the wall, and shutter means (not shown) for interrupting the electron beam when a closure member 12 is moved to allow passage of the plates through the aperture 11. A plate is moved to the operative position by means of a steel tape 15; when the spool 19 is unwound the tape pushes an unexposed plate 13 over a support 21 (which is then in the position shown by dotted lines) and over side supports 22 to the support 23. After exposure the tape is again unwound until a hook underneath the engagement member 14 on the end of the tape engages a slot 50 in the plate, after which the tape is re-wound and pulls the plate underneath the supports 22 and into the store 9. The stores 8 and 9 may be provided with a separate vacuum pumping system so that any water vapour evolved from the plates is kept out of the microscope. The shutter means (Figs. 6 and 7, not shown) may comprise a fixed aperture co-operating with a rotatable disc provided with four apertures and four pins which co-operate with two movable stop members. The disc is biased for rotation by means of a spring, which can be re-wound periodically by means of an electric motor, and the two stop members are retracted alternately by electro-magnetic devices so that the disc rotates step-wise from positions where it covers the fixed beam aperture to positions where an aperture in the disc is aligned with the fixed aperture.

Title: Graphite structures
IPC: C04B35/83
Filed: 1971-04-27
Abstract: 1343773 Fibre reinforced graphite structures UNITED KINGDOM ATOMIC ENERGY AUTHORITY 27 April 1971 [5 May 1970] 21655/70 Heading C1A Carbon fibre reinforced graphite articles are produced by impregnating a bundle of aligned carbon fibres with a liquid comprising a heat curable resin, heating the impregnated bundle to convert the liquid resin to a viscous material which binds the fibres together, shaping the resultant mass, heating it to completely cure the resin, and then carbonizing and graphitizing in non-oxidizing atmospheres. Before the initial resin treatment, the surfaces of the fibres used may be oxidized possibly by heating in air, e.g. at 400-600‹ C., or by immersing in a solution of an oxidizing agent, e.g. an aqueous solution of nitric acid or sodium hypochlorite. If desired before resin impregnation, and before or after surface oxidation the fibre may be immersed in a solution of a carbide forming element e.g. B, Be, Na or Si. The fibre bundle may be compression moulded and the shaping pressure may be maintained during the heating step required to hard cure the resin. Suitable resins are given and include coal tar pitch. The carbon body formed may be further impregnated with resin which may be cured and carbonized. If desired, after hard curing, the bundle may be further heated in air, e.g. at 200‹ C. to substantially eliminate volatile materials without any substantial loss by oxidation. Graphite powder or carbon black may be dispersed in the uncured resin.

Title: Hydraulic power assisted steering system
IPC: B62D5/24
Filed: 1971-04-19
Abstract: 1345352 Vehicle power steering V LANGEN [trading as LANGEN & CO] 19 April 1971 9759/71 Heading B7H  In a vehicle power steering apparatus a pump 1 supplies fluid under pressure to chamber 17 of power steering ram 14 and to operating valve 12. Valve 12 comprises a body 21 to which is rigidly attached steering column 19, 20 and which is rotatable inside casing 25 which is rigid with the vehicle body. Body 21 houses a piston 41 and an operating piston 42 of unequal areas 58, 47 which are slidable in bores 27, 29 and which may be operated by a pivotal two-armed lever 38 (which is part of column 19) by means of tappets 39, 40. Connections to pump 1 at valve 12 are made to: (a) bores 57, 59, 60 of piston 41 and (b) groove 53 in piston 42. Chamber 15 of ram 14 is connected to bores 49, 48, 46 while groove 52 of piston 42 is open to sump 2. Straight ahead operation (as in Fig. 3).-Pump pressure exists above piston 41 and the pressure of chamber 15 of ram 14 exists above piston 42. The effective areas f, F of piston 16 are, however, in the same ratio as areas 58, 47 of pistons 41, 42 so that lever 38 is balanced. Piston 16 is fixed in ram 14 by grooves 53 being blanked off so that the steering gear is held in the ahead position. Steering right (clockwise, Fig. 3).-The lever 38 is turned by shaft 19 forcing piston 41 up and allowing piston 42 to fall which connects bores 49, 48 (connected to chamber 15) to groove 52 (connected to sump). Piston 16 therefore moves to the right (Fig. 1) assisting the steering. Steering left (anticlockwise, Fig. 3).-Lever 38 is turned forcing piston 42 up which connects bores 49, 48 (connected to chamber 15) to groove 53 (connected to pump 1). Therefore ram 14 has equal pressures in both chambers and piston 16 moves left (Fig. 1) assisting the steering. The piston 41 of smaller area may assume the functions of the control piston as described above for piston 42. The piston 41, 42 may alternatively be of equal areas, the lever 38 having arms of unequal length.

Abstract: 1345736 Spindle feed; drilling heads; milling headstock; screwing headstock WAVIS ENG DEVELOPMENT CO Ltd 2 July 1971 31011/71 Headings B3B B3C B3K and B3N An automatic screw feed unit head, e.g. a plurality of which may form a machining centre around a work-table, in which a drive motor 27 rotatably drives a spindle 24 and the said spindle is fed axially by a screw and nut 30, 33 relative to a base member 20, is characterized in that a first element of the screw and nut feed, e.g. the nut 33, is rotatable and axially translatable relative to the base member but is non- translatable relative to the spindle, a second element, e.g. the feed screw 30, is fixed against both rotation and displacement relative to the base member, and wherein drive means is provided for transmitting rotary drive from the spindle through clutch means to the first element to translate the latter and the spindle relative to the base member at a feed speed, and a quick traverse motor is provided for rotating the first element in either direction to translate the spindle more rapidly, the clutch means then permitting rotation of the first element independently of the spindle. The spindle 24 is adapted to carry a drilling, milling or boring tool or a multi-spindle head. The drive means may be in the form of a removable drive unit 35 bolted to a sliding body 23 that carries the spindle 24. The drive unit 35 has a first input 37 from the spindle drive, a second input from the quick traverse motor, and a single output 36 connected to the rotary nut 33 via worm gear 53 and a sleeve 31. The drive unit 35 also includes the clutch means which may be electromagnetic or hydraulic, and a pair of gears (40), (41) (Fig. 4, not shown) which may be changed to alter a gear ratio without removing the drive unit from the body 23. In an alternative embodiment the feed screw is rotatably mounted in a thrust block 29 on the base member and the nut is rotationally and axially fixed to the body 23, the drive unit 35 being mounted in the thrust block 29, the feed screw then being driven either from the spindle drive for a feed motion or from a rapid traverse motor in the drive unit 35. Alternatively a separate, e.g. a third motor may be provided for the feed motion. The clutch has a torque override so that when the body 23 abuts a stop the clutch slips, e.g. to allow dwell at the finish of a drilling operation. Fig. 1 (not shown) shows a prior art unit head in which a spindle 9 is driven rotatably by motor 11 and also axially by the same motor via gearing to a rotatable nut 16 engaging a feed screw 4. For fast traverse a separate motor 6 rotates the feed screw 4, and an electromagnetic brake 8 is used to hold the feed screw rotationally fixed during a slow feed of the spindle.
