Title: Improvements in or relating to door locks
IPC: E05B63/20
Filed: 1937-01-27
Abstract: 482,364. Door latches. ARMSTRONG, F. G. G. Jan. 27, 1937, No. 5962/36. [Class 44] A door lock is fitted with a trip member resilientlv loaded and movable in a direction normal to the path of movement of the bolt, to hold the latch bolt in a partially shot position until the door is fully closed, together with a safety catch loaded and movable in the direction of bolt movement, which is displaceable against its load whilst the latch bolt is held by the trip member. The latch bolt 22 retracted by the follower 28 is prevented from returning to the fully shot position by the trip member 56, a tongue 57 of which engages a recess 61 in the bolt. This member is released on fully closing the door by the projection 37 of the keeper plate 36. A spring controlled catch 63 mounted in the keeper 36 allows the latch bolt 22 to pass when it is in the partially shot position during closing movement of the door but prevents re-opening unless the latch bolt is withdrawn. In a modification in which the catch 66 is embodied in the bolt head, Fig. 5, the keeper member 36 has an auxiliary notch 42 formed in it to co-operate with this catch. A rubber pad or buffer 33 carried by the rib 25 of the fixed guide 21 co-operates with the rib 24 of the bolt to ensure silence when the bolt is shot under the action of spring 26.

Title: Improvements in or relating to phosphor combinations
IPC: G21K4/00
Filed: 1951-03-13
Abstract: 687,231. Luminescent screens and materials. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 13,1951 [April 27, 1950], No. 5979/51. Class 39(i) [Also in Group XL(b)] A composite phosphor for scintillation counters of gamma and X-ray radiation comprises a polycyclic organic phosphor and an inorganic phosphor disposed in contact therewith, the combined phosphors giving non-directional light output characteristics and having a more uniform correlation between light output and the roentgen rate when exposed to the radiation than either phosphor alone. The organic compound may be anthracene, naphthalene, phenanthrene, stilbene or a poly carbocyclic compound. Suitable inorganic phosphors are cadmium tungstate, calcium titanium silicate, calcium titanium stannate and cocrystallisation products of lanthanum silicate-cerium oxide, calcium ortho-phosphate-stannate and calcium ortho-phosphate-cerium oxide. Both phosphors may be single crystals. A scintillation counting device has a light tight housing containing the holder 14 for the composite phosphor and a multiplier phototube with a high amplification, e.g. one million. The electrical recording apparatus may also be enclosed or be remotely controlled. The holder 14 comprises an opaque shell 30 made of a moulded plastic such as phenol-formaldehyde resin or hard rubber, the material having been heavily pigmented. Alternatively, a metal penetrable by the radiation is used. In a recess 32 is an organic phosphor crystal or crystals 34. A smaller amount by weight of an inorganic phosphor 36 is positioned on the lower face of the crystal 34. A single inorganic phosphor crystal is desirable but it may be powdered and applied to the face or disposed inside the crystal 34, e.g. as a thin layer between two pieces of the crystal 34. A greater weight of phosphor is required when it is powdered. A bent light transmitting member 38 closed by a cover 44 is used to calibrate the device. The material may be quartz, polymethyl methacrylate, polystyrene or a polyester resinous polymer, each having the necessary high index of refraction for transmission of light when the cover 44 is removed. In the examples, the composite crystal, comprises (1) anthracene 99.5 per cent and cadmium tungstate 0.5 per cent, each as a single crystal and (2) anthracene 92-97 per cent and a cocrystallised product of 98 mols. calcium ortho-phosphate and 2 mols. tin oxide 3-8 per cent. The light output is constant from -50‹C to +50‹C. The inorganic phosphor may be cocrystallised from a common solution by gentle heating to drive off the solvent, long periods of time, e.g. several weeks, being required.

Title: Improvements in or relating to flux cored solders
IPC: B23K35/02
Filed: 1939-02-23
Abstract: 525,583. Soldering. BARNETT, J. Feb. 23, 1939, No. 6064. [Class 83 (iv)]. In making a flux-cored solder, flux such as rosin is extruded from a nozzle to form a flux cored solder containing a single core of flux which constitutes at least 7 per cent. of the total weight thereof and one or more plain solder wires are then twisted together with the cored wire to reduce the weight of flux to the normal 3 to 5 per cent. Preferably two plain wires are used each of half the cross-sectional area of the cored wire, where cross-sectional area of flux is half the total cross-sectional area, so that the flux comprises 10 per cent. of the total weight of the cored wire. The core may be non-circular with a periphery at least 25 per cent. greater than the periphery of a core of circular crosssection of the same cross-sectional area. It may consist of three limbs or eight or twelve radiating fingers connected to a central portion. Interruptions in the flux constituting the core are thus avoided. Specifications 476,697, 484,988 and 494,906, [all in Group II], are referred to.

Title: Apparatus for determining the speed of moving strip material
IPC: G01P3/26
Filed: 1973-02-08
Abstract: 1402204 Speedometers DAVY-LOEWY Ltd 16 April 1974 [8 Feb 1973] 6212/73 Heading G1K [Also in Division G3] Apparatus for determining the speed of strip material 5, Fig.1, moving in the direction of its length comprises a sleeve 1 which is supported in spaced relation to a stationary core 2 by pressure gas supplied through passages 4 and is rotated by engagement with the strip. A further passage 8 in the core receives the pressure gas from the space 3 and is connected to means for detecting variation of the gas pressure. One or more axial grooves 6 in the sleeve create sudden drops in pressure in passage 8 at a frequency which is dependent on the rotational speed of the sleeve. These pressure drops are picked up by the detecting means and hence the linear speed of the strip can be determined. The detecting means may be a transducer which produces an electrical signal representative of pressure. A respective apparatus of the invention may be arranged upstream and downstream of a mill for rolling metal strip, with the latter driving the respective sleeves, Fig.2 (not shown). Thus by comparing the number of pressure reductions occurring in the two apparatus, the ratio of ingoing and outgoing strip speed is determined and consequently the elongation of the strip as it passes through the mill can be found.

Abstract: 1,156,776. Coating apparatus. C. PRICE CO. 13 Feb., 1967 [20 June, 1966], No. 6800/ 67. Heading B2L.  In coating the surface or a pipe or elongated member with a thermosetting synthetic resin initially in in powdered form, the surface is heated to a temperature at least equal to the minimum temperature at which the powdered resin is rendered fusible but below the minimum curing temperature of the resin, the powder is entrained in an air-stream and is discharged thereby against the surface which the latter as at the treating temperature and while the pipe or member is rotated about its longitudinal axis, whereby the resin adhers to the surface, land the temperature of the resin adhering to the surface is elevated to at least said minimum curing temperature for sufficient time to cure .the coating. Preferably the surface is cleaned prior to heating by air blasting with a particular abrasive substance and directing a fluid under pressure at the surface. With the apparatus shown, pipe 62 after being cleaned and pre-heated to approxima- 'tely 350‹F is supported for rotation and a lance 26 mounted on a carriage (12) on tracks (18) (Fig. 2 not shown) and having an electrostatic discharge head 46 is inserted through the pipe 62. resin powder is carried in a fluidized state in a reservoir on carriage (12) and is fed at the lance via conduit 42. The lance is surrounded by a jacket 28 through which cooling medium is circulated to prevent the powder fusing in the tube 26 and the jacket 28 carries guide rollers 84. The discharge lead may be such as to cause the resin carrying air stream to flow over the internal surface of the pipe in a helical or conical path as the lance moves through the pipe. The lance carriage (12) may have control arrangements to effect automatic insertion and withdrawal of the lance assembly at a desired speed and in synchronism with the delivery of successive pipes. After the coating operation the pipe is conveyed to a soaking oven where the temperature of the coated surface is raised to approximately 450‹F for curing the coating. Subsequently the external surface of the pipe may be coated' by an exterior electrostatic coater and then conveyed to a water quencher.
