Title: Improvements in or relating to methods of jointing surfaces by heat-hardenable resins
Inventor: REES JOHN
IPC: B29C65/36
Filed: 1952-12-16
Abstract: 778,684. Laminates. BRISTOL AIRCRAFT, Ltd. Dec. 4, 1953 [Dec. 16, 1952], No. 31913/52. Drawings to Specification. Class 140. [Also in Group XI] A surface of fully cured heat-hardenable resin is joined to another surface of the same or a different material by introducing between the surfaces a heat-hardenable resin adhesive and a plurality of electric conductors which either consist of strips of metal foil, or are supported in a pre-arranged pattern by a sheet of insulating material, pressing the surfaces together, and causing an electric current to pass along the conductors to generate heat to harden the adhesive. The fully-cured resin of which one or both surfaces is formed may be phenol-, cresol-, aniline-, urea-, or melamine-formaldehyde. The heat-hardenable - resin adhesive, which may be an epoxy resin, may be in the form of a solid film which is employed as the support for the electric conductors, e.g. the conductors may be arranged between two sheets of thin felted or woven fibrous material impregnated and stuck together with a partlycured, water-soluble, phenol-formaldehyde resin. If the adhesive process employs a heathardenable resin in conjunction with a thermoplastic substance, the latter may be in the form of a film carrying the electric conductors. Alternatively, the conductors may be carried by a film of polythene, which is dispersed out of the joint during the heating operation. The electric current may be caused to flow in the conductors by applying a difference of potential to the ends of one or more conducting paths, or the conductors may form one or more closed circuits in which current is generated by an alternating electromagnetic field. Mouldings may be joined to form the aircraft wings described in Specification 778,681, [GroupXXXIII]. Specification 778,683, [Group V], also is referred to.

Title: Device for use in taking blood samples
IPC: A61B5/15
Filed: 1972-07-07
Abstract: 1389871 Taking blood samples PRO MEDICAL ENG AB 7 July 1972 [5 Oct 1971] 31952/72 Heading A5R [Also in Division F2] A device for taking blood samples comprises a part 1, Fig. 1, for carrying a hollow needle, and a junction part 11, Fig. 2, for fitting together with part 1 and for connection to an evacuated vessel, the part 1 having a duct 3 for communicating with the needle bore, a valve member 2 with a vent hole 4 leading to duct 3 and a resilient sleeve 7 which can seal hole 4, the part 11 having a bore 14, 15, 16 in which a sleeve 13, sealingly engageable with member 2, is movable between first and second limit positions, a vent hole 22 from a passage 21 in sleeve 13 communicating with the atmosphere in said first limit position, the second limit position allowing, when parts 1 and 11 are connected together and to the needle and evacuated vessel, a passage from the needle bore via duct 3, hole 4, passage 21, hole 22 and bore 16 into said vessel. When the parts 1 and 11 are assembled, sleeve 13 engages sleeve 7, which is thereby pushed partly onto a tapering base 6 of member 2, hole 4 remaining sealed by sleeve 7 until fins 8 thereon engage the ends of slots 9 in part 1. Prior to opening of hole 4, any air compressed by the assembling movements is vented via hole 22 and via grooves 25 in sleeve 13. Further movement of parts 1, 11 together causes sleeve 13 to engage between sleeve 7 and member 2 to uncover hole 4, relative movement between sleeve 13 and member 2 being stopped when the end 2' engages a stop surface 24 of sleeve 13. Continued assembly forces a bead 20 on sleeve 13 past projections 18 until bead engages a shoulder 17 defining the second limit position. During disassembly of parts 1 and 11, the sleeve 13 is initially pulled to a position at which bead 20 abuts the sides of projections 18 nearer to shoulder 17, hole 22 then being closed by a portion 14 of part 11. In alternative embodiments movement of sleeve 13 between its limit positions is effected by relative rotation between the sleeve 13 and the junction part 11, Figs. 4, 6 (not shown). The communication between the needle bore and the passage in the junction piece sleeve may alternatively be established by relative rotation between the valve member and its resilient sleeve, Fig. 6. The part 1 and sleeve 7 may be made of transparent plastics material.

Title: Improved interlocking mechanism for machinery guards
Inventor: HOWE WILFRED
IPC: F16P3/08
Filed: 1949-12-17
Abstract: 677,280. Machinery guards; screw-and-nut gearing. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd. March 16, 1951 [Dec. 17, 1949], No. 32408/49. Classes 80 (iii) and 80 (iv). In a locking device for machinery guards wherein the guard is mechanically locked by an element coacting with a micro-switch in the circuit of the driving motor, the device is operated by screw-and-nut means. The micro-switch 11 is operated by a rod 39 which is slidably mounted in a partition 4 and a block 5 of a casting 1, and which carries collars 40, 41 engaged by a collar 50 on a screw-threaded member 43. The member 43 has a handle 48 and coacts with a quickrelease nut formed by two spring-pressed L- shaped members 25, 26, Fig. 2, pivotally mounted in slots in the block 5 so that the handle 48 may be pushed to close the switch 11. Secured to the guard is an extension 56 having a hole 57 through which may pass the rod 39, thereby locking the guard before switch 11 is closed. To release the guard, the member 43 must be unscrewed, thereby first opening the switch 11 and subsequently, after considerable further rotation, by which time the moving parts have come to rest, releasing the extension 56. If the guard is then opened and the extension 56 retracted, a spring-pressed slide 34 covers the hole in the partition 4 and prevents upward movement of the rod 39. A sleeve 54 encloses the mechanism which is attached to the machine frame. Alternatively the mechanism may be attached'to the guard and the rod 39 coact with the frame. In a modification the member 43 itself constitutes the locking element. According to the Provisional Specification the device is applicable to guards for the knives and gearing of rotary tobacco-cutting machmes.

Title: Lens stabilization arrangement
IPC: G03B19/18
Filed: 1966-07-20
Abstract: 1,145,795. Optical sights. BELL & HOWELL CO. 20 July, 1966 [29 July, 1965], No. 32583/66. Heading F3C. [Also in Divisions G1 and G2] The line of sight of optical instruments such as cameras, binoculars, telescopes or gunsights is stabilized by mounting a lens 12, Fig. 2, on a rotor 14 which has a spherical surface thereon and rotatably driving the rotor 14 by a device 56 which only contacts a portion of the spherical surface. As shown applied to a cine camera lenses 8, 12, form a variable optical wedge in front of the camera objective 26, lens 8 being fixed with respect to the camera. On rotating drive shaft 74 by a motor (not shown), rubber ring 72 causes rotation of device 56 which frictionally drives the rotor 14. When the camera vibrates, the spin axis of rotor 14 tends to remain fixed in space so that lens 12 moves relative to lens 8 to compensate for such vibration. On panning the camera, however, the frictional forces tend to precess the rotor axis into alignment with the camera axis. To vary the rate of such alignment a circular spring element 116 threadedly engaged with the support 50 may be moved towards or away from the rotor 14. Alternatively, Fig. 1 (not shown), a series of screws (100) may be rotated to vary the pressure exerted by a series of springs (114) on a ring (106) contacting the rotor (14). In another embodiment, Fig. 9 (not shown), the spherical surface of the rotor (120) is contacted on opposite sides of its medial plane by a pair of members (132), (134), adjustably screwed together to vary the frictional forces exerted on the rotor (120). In a further form, Fig. 10, the rotor 164 has an internal spherical surface 165 which is engaged by a knife edge 172 on the rotatably driven member 168. In each embodiment provision is made for balancing the rotor about the intersection of the spin, drive and precession axes which is also the centre of curvature of the spherical surface of the rotor and the outer surface of the lens.

The channel may be sub-divided into smaller compartments by radially disposed grids 18, such as a series of bars, extending from the central support 17 to the inner surface of the casing. The grids retain the carrier bodies in the sub-compartments but permit the passage of partially dried material from one compartment to another.  In a modification, the material to be dried and the carrier bodies progress together to the discharge outlet where a grid 27, Fig. 3, is arranged of sufficient size to permit passage of the dried material only, the carrier bodies being admitted through an aperture 28 to the hollow central support 24 which provided with an independent worm conveyer 24<a> returns them to the charging end of the apparatus.  In a further modification, the central support 24 is of conical form, the smaller end being disposed at the discharge end of the apparatus.  The carrier bodies may comprise spherical or cylindrical solids, apertured hollow cylinders, ring-shaped elements, rectangular sectioned helical elements or chains.  The apparatus may be combined in one structure with a rotary kiln, the dried material being fed thereto.

Abstract: 659,765. Powder metallurgy. SKODA WORKS, NATIONAL CORPORATION. Dec. 17, 1948, No. 32713. Convention date, Dec. 19, 1947. [Classes 83 (ii) and 83 (iv)] Making drills and lathe and like tools.-A shaped body of sintered hard metal alloy consisting of one or more carbides of titanium, zirconium, hafnium, vanadium, niobium, tantalum, tungsten and molybdenum and of a binding metal of the iron Group, comprises outer zones having a lower proportion of the binding metal than the inner portions. In a WC-Co alloy the core contains 11-13 per cent cobalt and the surface zone 5 per cent. The core may thus have a tensile strength of 220 kg./mm<SP>2</SP> and the surface 120 kg./mm<SP>2</SP>. The body may consist of a number of different layers of powder pressed together. Alternatively, the layers may be sintered individually and joined by intermediate layers having a higher proportion of binding metal, e.g. 13 per cent Co in layers joining parts of 4 per cent Co. The sintering is carried out in a reducing atmosphere. Thus a twist drill may have a centre R, Fig. 1, having a higher cobalt content than the outer zones. A tool tip, Fig. 2, has an outer surface A of WC-TiC with 4-5 per cent Co and a centre portion R of WC and 11--13 per cent Co.

The temperature of the mixture is maintained below the inverse critical solution temperature of the amine to yield a solid and a single liquid phase; the solid phase is then separated from the liquid. After separation, the liquid temperature is preferably allowed to rise above the critical solution temperature and the amine and water phases formed are separated. The preferred amine is triethylamine. Preferred materials for dewatering are aerobic and anaerobic sewage sludges and a hydrated alum sludge, which is a waste product from potable water treatment processes.
