Patent GB-217367-A (GB)
Title: Automatic lock
IPC: E05B63/12
Filed: 1923-04-07
Abstract: 217,367. Lanphere, C. W. April 7, 1923. Spring locks; sliding bolts; striking plates and staples for locks. - An arc-shaped follower-retracted spring-shot sliding; bolt is held in its fully retracted position by a detent which is released by a trigger when the door is closed. The bolt 24 has a tail 46 and an arc-shaped spindle 48 carrying the shooting spring 47. Guides 27 are formed on the casing. In the position shown in Fig. 1, the bolt is held fully retracted against the spring 47 by the engagement of the arm 32 of the detent 28 in a slot 31 in the bolt. On slamming the door, the trigger 35 is forced inwards by the striking plate, moving the rod 29 against its spring 36 which results in the removal of the detent arm 32 from the notch 31, when the bolt shoots out under the action of its spring 47 into the staple. A member 42 rises under the action of a spring to engage a shoulder 43 on the detent to hold it in the inoperative position. To release the bolt, a follower operated by a key from outside the door, engages a projection 37 on the bolt and retracts it until arrested by the stop 38. The end of the bolt 24 then presses the member 42 downwards and allows the detent to spring forward to engage the projection 32 in the notch 31 when the door is opened and the trigger 35 can spring outwards. A spring 65 restores the follower to its original position. In the modification shown in Fig. 7, the trigger 35 is shown cut away and an additional spring catch 57 is shown engaging a notch 62 in the end of the bolt to prevent its being forced back. When release is desired, the handle follower 33, or the lock follower. engages a tail 61 to withdraw the catch 57 before engaging the projection 37 on the bolt. A rod 39<1> may also be provided to hold the bolt in its retracted position by engaging a recess 40<1>, a push button 40 connected to the rod 39<1> by a lever 19 ensuring release of the rod on closing the door. The staple has a part 42<1> round which the bolt 24 engages. A plate 64 curved to fit the bolt may also be provided in the staple. The staple has bevelled ends 66 and can be raised by packing, to compensate for sagging of the door.

Title: Improvements in or relating to spigot-and-socket joints
IPC: F16L25/06
Filed: 1953-04-09
Abstract: 730,339. Pipe joints. VICKERS-ARMSTRONGS, Ltd., and MOBSBY, P. G. Feb. 23, 1954 [April 9, 1953], No. 9659/53. Class 99 (1). A joint for connecting hollow cylindrical members 13, 14 comprises a socket ring 11 having an internal annular groove 15 in which a split ring 17 can be wholly accommodated, a spigot ring 10 provided with an external annular groove 16 which is aligned with the groove 15 when the rings 10, 11 are assembled together, and a series of screws 21 mounted in radially-extending screw-threaded holes in the wall of the ring 11. The screws 21 engage the ring 17 at intervals around its periphery and force the ring partially out of the groove 15 and into the groove 16 to lock the rings 10, 11 together. The groove 16 may have a chamfered side 19 which co-operates with a corresponding chamfer 18 on the ring 17 to enable a wedging action to be obtained when the ring is projected into the groove. Relative rotation between the rings 10, 11 may be prevented by providing inwardly directed dowels 22 on the ring 11 and for engaging in longitudinal, open-ended slots 23 in the ring 10. In a modification, a split torsion ring 25, Fig. 6, substantially cylindrical in shape and held at 28 between the rings 10, 11 is twisted to engage in the groove 27 of the ring 10.

Abstract: 1417444 Preparation of hydrogen SULZER BROS Ltd 1 March 1973 [2 March 1972] 9946/73 Heading C1A Hydrogen having a natural deuterium concentration is produced by supplying steam 3 having a natural deuterium concentration and a hydrocarbon feedstock 4 to a thermal hydrogen production plant A and recovering the hydrogen 12; excess water (of increased deuterium concentration) is recycled via isotope exchange column 15 to increase the concentration of deuterium in at least a portion of the steam supplied. The invention also comprises the corresponding apparatus. The plant A comprises a primary reformer 1 which contains a catalyst, e.g. Ni oxides surrounded by a combustion chamber 2 receiving fuel and air. Steam from fresh water at approximately 600‹ C. is supplied to reformer 1 through line 3 and hydrocarbons at approximately 300‹ C. are supplied to reformer 1 through line 4. The mixture, at approximately 700‹ C., passes to secondary reformer 5 via line 6 and is catalytically oxidized over nickel oxides with the aid of air from line 7 to H 2  and CO. The gas mixture at approximately 1100‹ C. is cooled in heat exchanger 9 and enters converter 10 which has an upper catalyst in the form of Cr oxides and lower catalyst in the form of Cu and Sn oxides. CO and H 2 O react exothermically to give H 2  and CO 2  and converter 10 has a cooling jacket 11. The mixture leaves the H 2  production plant via line 12 after excess water has been removed in condenser 13. The H 2  in this mixture has a deuterium concentration approximating to a natural concentration.

Title: Rubber containing compositions and method of preparation thereof
Inventor: STOBER KENNETH ELMER
IPC: C08L21/00
Filed: 1959-03-23
Abstract: Non-agglomerative compositions consisting of natural or synthetic rubber particles coated uniformly with the dust of a vinyl aromatic polymer, e.g. polystyrene, preferably include 1 to 30%, more suitably 2 to 10%, by weight of the polymer dust, at least 50% of which is finer than 100 mesh, U.S. Standard Sieve, at least 50% by weight of vinyl aromatic compound being contained in the polymer molecule.  The polymer dust may be obtained by grinding, or spray-drying latex emulsions of, materials such as styrene or vinyl-toluene polymers or their copolymers with methyl styrene or acrylonitrile, polymers or copolymers of halo-styrene, and interpolymers of styrene with styrene-butadiene copolymers. Suitable rubber particles to be coated with the dust may be obtained by grinding or comminuting rubber, or alternatively, crumbs coagulated from latex emulsions may be used, and the polymer dust may be blended directly therewith, or added during the comminution process thereby preventing the adhesion of already subdivided particles.  Besides polystyrene dust, of molecular weight preferably not less than 20,000, the dust of styrene-buatadiene copolymer may be used and the dusted particulate rubber compositions are particularly suitable for blending with liquid vinyl aromatic polymers, e.g. styrene, in the preparation of graft co-polymers.

Inventor: SUMMERS GEORGE ROBERT
IPC: A61L9/16
Filed: 1998-04-17
Abstract: A lightweight portable germicidal air filter for home and personal use is disclosed. The air filter includes a cabinet which houses an electrostatic air filter, an ultraviolet lamp and a parabolic reflector or a convex lens for focusing the ultraviolet radiation emitted by the lamp on an upstream side of the air filter. The reflector or the lens are constantly oscillated to systematically sweep the upstream side of the filter with germicidal levels of radiation. A fan located adjacent the downstream side of the filter draws air through the filter and impels it out through areas for air outlet in the sidewalls of the cabinet. The advantage is a simple, lightweight germicidal air filter with few moving parts which is inexpensive to manufacture.

Filed: 1989-01-09
Abstract: PURPOSE:To display a picture with fidelity to color reproducibility on a monitor screen by applying a sweepout pulse to a solid-state image pickup element on the way of storing a signal charge in at least one color field among R, G, B fields. CONSTITUTION:When R, G, B enable signals are inputted to a charge storage time control signal generator 19, the information relating to the application timing of an inverse transfer pulse RP is read out of a charge storage time setting device 18 and inputted to a timing pulse generating circuit 11. The inverse transfer pulse RCP is inputted to a CCD 9 to sweep out the charge stored so far to the drain. Then a photodetection section stores the charge again and a transfer pulse TP is applied at the vertical blanking period VB and the signal charge stored in the photodetection section is transferred to the storage section. Thus, the color reproducibility of a reproduced picture is remarkably improved, white saturation is improved and coloring of the picture at a dark place or an intermediate light part is not caused.
