Title: Improvements in or relating to machines for the manufacture of moulded articles from plastic moulding compositions
IPC: B29C48/475
Filed: 1932-07-11
Abstract: 401,428. Extruding plastic substances. ROCKHARD RESINS, Ltd., Abbey House, Baker Street, London, and JONES, F. W., 19, Park Hill Road, Croydon. July 11, 1932, No. 19588. [Class 87 (ii).] Rods, tubes, beading &c. of thermo-setting plastic materials are made by extruding the material against a definite and predetermined pressure. The material is fed into a hopper C communicating with a mould A<1> in which reciprocates an hydraulically actuated ram D, forward movement of which is effected by a plunger D<1> while the return stroke is effected by the plunger rod D<4>. The material is extruded through a die A<2> of the required cross section and the extruded column may, during its movement, be gripped by magnetically actuated pivoted clamps E, carried by a ram F<4> which slides on guides F<2> against predetermined hydraulic pressure. In a modification, clamps E Fig. 3 are mechanically engaged with the extruded bar by cam actuated linkage N<2>, N<3>, the ram D also being crank driven in this case. In a further modification, the extruded bar is passed into a guide tube in which it abuts against a co-axial plunger which moves rearwardly with the bar against hydraulic pressure. The counter-pressure may also be applied by a weight, spring or electro-magnetic means. The mould and die may be cooled at J<1> and J, and electrical heating may be applied at K.

Title: Adhesive composition
IPC: A61K6/00
Filed: 1971-06-10
Abstract: 1343790 Cyanoacrylate adhesives JOHNSON & JOHNSON 10 June 1971 [11 June 1970] 19898/71 Heading C3P Cement compositions comprise a polymerizable monomeric cyanoacrylate ester of the formula CH 2  = C(CN)-CO-OR wherein R is C 1 -C 16  alkyl, cyclohexyl or phenyl; 1-4 parts by weight (per part of monomeric ester) of a finely divided filler; and from 5-25% by weight (based on the total cement composition) of finely divided sodium fluoride. Suitable fillers include fused silica, quartz, alumina and finely divided polyethylene, and preferably 25-75% by weight of the filler has particle sizes in the range 40-50 microns and 75-25% by weight 90-100 microns. The filler may contain an amine activator and can be stabilized against loss of activator activity by treating with triphenyl silane or a non-catalytic trialkoxysilyl compound. The sodium fluoride preferably has particle size in the range 10-100 microns. The compositions are particularly useful as dental cements and for this purpose can optionally be pigmented, e.g. with finely divided carbon. They are also suitable for filling or bonding materials such as ceramics, glass, metal, wood and rubber.
Patent GB-673474-A (GB)
Title: Improvements in and relating to automatic electric circuit opening devices
IPC: H01H75/04
Filed: 1949-07-29
Abstract: 673,474. Automatic circuit - breakers. BRITISH THOMSON-HOUSTON CO., Ltd. July 29, 1949. [July 31, 1948] No. 19987/49. Class 38 (v). Branch and sub-branch circuit-breakers, suitable for use in the system described in Specification 667,068, comprise a modification of the breaker of Specification 650,509, the release of the holding means being blocked until a predetermined one of a number of current impulses. The blocking means comprises a lever 62, biassed clockwise by gravity, but normally held in the shown position by a latch 65 held in this position by the engagement of its other end with the smooth periphery of a ratchet wheel 95. Full upward movement of the armature 34 is prevented by the engagement of a pin 82, carried by extensions 46 thereof, with the lever 62. The upper ends of the extensions 46 are joined by a plate 48 upon which rests a thrust bearing 59 and a plate 57 frictionally engaging a flywheel 61, the plate 57 also having a slot engaging a fixed screw 56. On upward movement of the armature, the flywheel is raised and on de-energization of magnet 31, it falls slowly due to its rotational inertia. The upward movement of the armature also causes a pin 81 to raise a lever 73 so that a spring-pressed pawl 72 thereon engages and rotates the wheel 95, which is prevented from returning by a pawl 76 on a spring-controlled lever 78 normally held out of engagement with the wheel 95 by a rod 79 held down by the fly-wheel. Thus, due to the slow fall of the flywheel, the pawl 76 is allowed to remain in contact with wheel 95 and subsequent energizations of magnet 31 cause the wheel 95 to be stepped round until the tail of latch 65 engages a V-notch 71 therein, thereby releasing the lever 62 which moves clockwise when the armature drops and allows the armature to rise to its full extent on the next impulse to trip the circuit-breaker. The flywheel eventually returns to its normal position and thereby disengages the pawl 76 by means of rod 79, and resets the lever 62 and latch 65, the wheel 95 being returned to its normal position by a spring 68.

Title: Improvements in fluid heater cleaners
Inventor: TOLLOW FREDERICK SIDNEY
IPC: F28G3/16
Filed: 1961-06-02
Abstract: 986,134. Soot blowers. BABCOCK & WILCOX Ltd. June 1, 1962 [June 2, 1961], No. 20086/61. Heading F2N. In a fluid heater cleaner having an elongated lance or nozzle tube axially reciprocable to advance the tube from a retracted position and to withdraw the tube to the retracted position, there are means arranged to automatically rock the nozzle tube during reciprocation thereof in a manner tending to compensate sagging of the discharge end of the nozzle tube under the force of gravity acting laterally on the tube. As shown, the nozzle tube 1, extends through a support 6 fixedly mounted on a track member 7 and is supported by a rear support 8 and extends also through an intermediate support 10. The supports 8, 10 consist of wheeled carriages 24, 11 capable of movement along the track 7, and include inner members which allow rotation of the nozzle tube; the latter moves longitudinally relatively to the support 10 on rollers 15. A steam feed tube 31 secured to a support 32 extends coaxially of and within the tube 1 and is supported by rollers 42 on a wheeled carriage 34. A reversible electric motor 45 advances and retracts the nozzle tube and is arranged to drive, through a speedreducing gear 48, a shaft 47 coupled to a chain 53, the two runs of which respectively are attached to the carriage 24 of the support 8 and engageable with a sprocket 61 on a spindle 62 carrying a bevel gear 63 which meshes with a bevel gear 64 secured to the inner member 28 of the support 8 to rotate the nozzle tube. The chain 53 engages a sprocket 54 on a shaft 55 which drives by means of a chain a shaft 67 carrying a bevel gear 68 in mesh with a bevel gear 70 formed as a nut 71 and engaging a screwed shaft 73 coupled by a link 82 to bellcrank levers 84 on a cross-shaft 85 and connected by links 87 to brackets 88 on fixed supports; the frame 7 is also supported by a pivot 89. In operation the motor 45 is started in the appropriate direction and drives the chain 53 to project and rotate the nozzle tube, the steam valve 43 being then opened so that steam is discharged from the nozzle 3. As the chain advances the tube, the shaft 73 is moved longitudinally and through the link 82 effects rotation of the levers 84 to rock the frame 7 downwardly. As the tube 1 advances more and more the length of the unsupported part thereof beyond the support 6 bends more and more and the rear end of the frame is increasingly lowered with respect to the front end of the frame so that the forward end of the nozzle tube is more and more raised in opposition to the sag of the said forward end; the reverse obtains when the nozzle tube is retracted. As shown in Fig. 7, the supports 8 and 10 are moved to the forward end of the track 7 when the nozzle tube is fully advanced. In a modification, the frame 7 is pivoted at the front end thereof, but the rear end of the frame is suspended by a system of wire rope and pulleys forming a speed-reducing hoist. Specifications 636,052 and 769,593 are referred to.
