Title: Improvements in roll winding mandrels or rollers
Inventor: SHAW WILLIAM
IPC: B65H75/24
Filed: 1963-10-09
Abstract: 1,009,466. Rollers. WOOD & CO. (BLACKBURN) Ltd. Oct. 8, 1964 [Oct. 9, 19631, No. 39749/63. Heading F2U. A winding mandrel for cloth or the like comprises a tube 1 having an axially slidable blade 3, projected radially through a longitudinal slot 2, by the action of pins 5 on inclined slots in the blade. The end pins are provided with bushes 6 firmly supporting the blade to minimize wear on the blade and the edges of the slot 2. The blade is slid axially by a rod 13, acting, through a bearing 8 on a washer 7 abutting the blade, the other end of the blade abutting a spring- biased washer 14. The rod 13 can be locked in position by a screw 17 in a bracket 18 of the machine. The mandrel is driven by a driving shaft engaging an end plate 12. In operation material is wound on to the mandrel with the blade extended and the blade is then retracted to permit removal of the roll of material. Specification 614,090 is referred to.

Abstract: 1,079,759. Bearings. GLAENZER SPICER SOC. ANON. Sept. 30, 1964 [Oct. 2, 1963], No. 39786/64. Heading F2A. In a ball or roller bearing having a non- rotatable inner race 12, compensation for distortion of the outer race 11 when a radial force P is applied thereto is effected by shaping the inner race so as to render the radial distance between the two races uniform and the loads carried by the balls or rollers 13 ... 16<SP>1</SP> substantially similar to one another, the shape of the inner race being substantially elliptical when a single radial-force is applied to the bearing. When a plurality of radial forces are applied to the bearing, the radii of curvature of the profile of the inner race are determined in accordance with the magnitudes and directions of said forces so as to effect uniform loading of the balls or rollers. The inner race may be constituted by a solid shaft or hollow resilientlydeformable shaft (32), Fig. 4 (not shown). The hollow shaft may be rendered elliptical by insertion of an elliptical auxiliary member therein before a grinding operation, said member being removed when said operation has been completed. Alternatively, the inner race may be constituted by a ring mounted on a shaft. It is stated that the balls or rollers may be omitted, the outer race being in direct contact with the inner race.

Title: Photographic camera for use with multilamp flashcubes of the percussive type
IPC: G03B15/04
Filed: 1968-08-23
Abstract: 1,243,843. Photographic flash-cube. apparatus. GTE SYLVANIA Inc. Aug.23, 1968 [Aug.23, 1967], No.40503/68. Heading G2A. A photographic camera has a mechanism which is designed to fire a percussive type flash-lamp, forming part of a flash-cube, in synchronism with the uncovering of a film exposure aperture. If a flash-cube is to be used, a button 142 on the camera front is depressed so as to displace a locking finger (30) Fig. 9 (not shown) to allow insertion of a flash-cube into a socket 28, release of the button causing the finger (30) to lock into a groove (5) of a lamp (3). The film is then advanced, actuation of the film advancing lever also cocking the shutter 52, rotating the socket 28 through a link and cam, and cocking a flash-lamp firing hammer 62 by means of rotation of a shaft connected to the socket 28. The linkage system is arranged by means of a two piece sleeve (100) Fig.4 (not shown), to allow of further actuation of the film advancing lever without disturbing the rotated flash-cube and the cocked hammer. The lower component (102) of the sleeve (100) rests on a leaf-spring (104) which normally biases the two sleeve pieces into contact. As the hammer 62 approaches its cocked position, it displaces a pin 90 to the lower end of a slot 88, and this rotates a lever (130) so that a tab (134) thereof depresses the leaf-spring (104) thereby disengaging the components (102), (98). To take a picture, the operator depresses a shutter release plate 40 thereby rotating an arm 42 to free a detent 46 from a finger 48 of the shutter striking plate. However, this plate does not, as yet, trip the shutter as it still held by a detent 82 of a shutter tripping lever 78. Rotation of the arm 42 displaces a hammer latch 70 thereby releasing the hammer 62 which advances a firing pin (38) into engagement with the primer cup (1) of the lamp (3). As the hammer approaches the end of its stroke, the detent 82 is displaced freeing the finger 48 and allowing the shutter striking plate to trip the shutter.

IPC: C08J5/06
Filed: 1963-10-21
Abstract: The bonding of polyethylene terephthalate fibres to natural or synthetic rubber, e.g. cispolymers of butadiene and isoprene, polymers of chlorobutadiene and copolymers of these monomers with styrene, acrylonitrile, methyl methacrylate, ethylene, propylene or isobutylene, is improved by treating the fibres with an aqueous adhesive system comprising a butadiene/vinyl pyridine copolymer and a resorcinol-formaldehyde resin solution and with an aqueous suspension of an isocyanate generator prepared by the reaction of a polyisocyanate-polyhydric alcohol reaction product with a phenol. The dispersion of the isocyanate generator may be mixed with the aqueous butadiene/vinyl pyridine latex and resorcinol-formaldehyde resin solution and the fibres impregnated with this dispersion and heated for a short time at temperatures above 140 DEG C. Alternatively the fibres may be impregnated with the p  isocyanate generator and with the latex and resorcinol-formaldehyde resin solution separately in either order, the fibres optionally being heated between the two impregnation treatments.  The isocyanate generator may be prepared by the reaction of 2,4-or 2,6-tolylene diisocyanate with ethylene glycol, diethylene glycol or glycerol followed by reaction with phenol or with a substituted phenol.

The auxiliary boilers and turbines are of lower capacity than the main boilers and turbine. A high temperature helium cooled nuclear reactor comprises core 12 within, and cavities 30, 38 arranged around the periphery of, a concrete pressure vessel 14. The turbines 20, 26 respectively drive a main alternator 22 and two auxiliary alternators 28. Main boilers 16 have economizer and evaporator section 32 and a super heater section 34. Coolant pumps 36 circulate coolant down through the core 12 and up through the main boilers. Coolant pumps 42 circulate coolant down through the core, down through economizer, evaporator and superheater sections 40 of auxiliary boilers 24 and then upwards through a central duct (50) Fig. 4 (not shown) to the top of the core. Water is fed downwards through the main boilers and upwards through the auxiliary boilers to achieve counter-flow within the boilers. The main turbine 20 is a multicylinder turbine with high and low-pressure stages, reheaters 18 being provided between the stages and arranged in the cavities 30 to be heated by the coolant. Alternatively steam from the main boilers may be used to heat the reheaters 18 and subsequently to heat the feed-water heaters of the main boilers 16. During periods of large fluctuations in load demand the main turbine and generator are run at a constant rate, the auxiliary turbines and generators being run under varying load. After shut-down the auxiliary boilers and turbines may be continued to run using the residual heat of the core. The feed water heaters are heated by steam bled from the main turbine.

Title: Improvements in and relating to gas blast circuit breakers
IPC: H01H33/82
Filed: 1964-10-15
Abstract: 1,049,497. Gas blast switches. BROWN, BOVERI & CO. Ltd. Oct. 15, 1964 [Oct. 17, 1963], No. 42073/64. Heading H2B. In a gas blast circuit breaker of the kind having two nozzle contacts 1, 2 separable in a chamber permanently filled with compressed gas and each associated with an outlet blast valve, the nominally fixed contact 2 is resiliently mounted and its follow-up action is employed to operate the associated blast valve obviating the need for transmission pipes or rods between the contacts and reducing the chance of creepage currents. As contact 1 is drawn upwards by a conventional linkage (not shown) contact 2 follows under the action of a spring 22 and the resultant internal gas pressure acting on a valve member 4. As the member 4 rises away from seat 10 a blast of gas escapes through an outlet 6a. In its upper position an abutment 4c on member 4 drives a valve member 20 upwards cutting off chamber 21 from channels 14a, 12 and outlet 6a and connects it through channels 15, 14b and 5a to the high pressure gas in the contact chamber 27 which drives valve member 4 back to the position shown. Towards the end of this last movement a ring 25 on member 4 draws the contact 2 back downwards to increase the gap, a damping piston 24 preventing rebound. During reclosure of the contacts, contact 1 drives contact 2 and thus valve member 20 back to the position shown.
