Abstract: 537,677. Photographic film cameras. KODAK, Ltd. Aug. 26, 1940, No. 13473. Convention date, Jan. 31. [Class 98 (i)] The film numeral aperture of a roll-film camera is covered by a light-shielding member carrying film type designations, and adjustable by means secured to it and extending to the outside of the camera so that the designation of the film in use is visible either through the numeral aperture or another, means being provided to retain the member in the adjusted position. As shown, a disc 10 is secured to a stud slidable in a slot 12 in the camera back and having an external slotted head 13 so that by inserting the edge of a coin the disc may be turned to exhibit in the slot 12 any one of a number of film designations carried on the face of the disc. The film shields the film from light passing through the film-number window 5, but when the film is to be wound the stud carrying the disc is slid to the top of the slot 12 so that the disc uncovers the window. A spring 17 engages notches in the edge of the disc to return it in its adjusted position, and also to urge it to its normal lowermost position. The film designations may be visible through the window 5 instead of through the slot 12.

Title: Coreless induction furnace melting of metals
IPC: H05B6/24
Filed: 1961-04-17
Abstract: 962,989. Induction furnaces. G. G. TURNER (Ajax Magnethermic Corporation). April 17, 1961, No. 13708/61. Heading H5H. A coreless induction metal melting furnace includes a refractory container encircled by a coil which is itself surrounded by a metal barrel, and laminated structures mounted between the coil and the barrel side wall and between the bottom of the container and the bottom of the barrel, respectively, for guiding the magnetic flux about the coil, the side structures being magnetically continuous with, but movable independently of, the bottom structures, for tightening the coil against the side of the container. The coils 3, 4 and 5, Fig. 1, cooled by interior water circulation, are wound about the refractory container 2 for molten metal 1, the section 4 extending beyond the container bottom, and only the middle section 3 being energized. Mounted on the detachable base 7 of the metal barrel 6 are laminated magnetic members 11 and 12, Fig. 5, on which a corresponding number of similar members 8, Fig. 4, can slide. Members 8, which are of laminated silicon steel or iron, with a central reinforcement of ordinary steel of reduced width, 15, are movable radially in either sense between the coils and the wall of barrel 6, by screws 9 and 10, whereby resilient insulating material packed into the channel defined by strip 15 can be pressed against the outside of the coils. The furnace can be attached to a tilting mechanism (Fig. 9, not shown). A system of wedges may alternatively be employed for moving members 8, and container 2 may be cylindrical, elliptical, conical, or rectangular with or without rounded corners. A modification employs, instead of members 8, two semicylindrical members together surrounding the container, and movable towards one another. A further modification (Figs. 12 and 13, not shown) employs instead a single arcuate member almost closed upon itself to form a cylinder, which member can be deformed by screw pressure to grip the coils. The method of assembling the furnace is described. Specification 962,988 is referred to.
Patent GB-597338-A (GB)
Title: Mineral oil composition
IPC: C07F9/04
Filed: 1945-05-31
Abstract: Mineral oils, particularly viscous mineral lubricating oils such as solvent-refined motor oils, are improved with regard to their resistance to oxidation, corrosion of corrosion-susceptible bearings, and piston ring sticking and sludge forming tendencies in internal combustion engines, by the addition of a minor proportion (usually 0.01-1.0 per cent.) of a phosphorus and sulphur-containing reaction product obtained by reacting a phosphorus sulphide with a dicyclic terpene, or an essential oil predominantly composed of a dicyclic terpene.  In examples, either pinene or American turpentine, either alone or mixed with about equal proportions of a refined viscous mineral oil, are reacted with phosphorus pentasulphide in the proportion of 4 mols of the terpene to one of phosphorus pentasulphide, at temperatures between about 100 DEG C. and 160 DEG C., a small proportion of decolorising clay added, the resultant mixture filtered, and any unreacted pinene removed by distillation under reduced pressure. Monocyclic terpenes and olefinic hydrocarbon terpenes are unsuitable.ALSO:Hydrocarbon derivatives containing phosphorus and sulphur employed as antioxidants for lubricating oils are prepared by reacting a phosphorus sulphide with a dicyclic terpene, or with an essential oil predominantly composed of a dicyclic terpene.  In an example, either pinene or American turpentine are reacted with phosphorus pentasulphide in the proportion of 4 mols. of the terpene to one of phosphorus pentasulphide at temperatures of about 100-160 DEG  C. without a catalyst.  Unreacted pinene is subsequently removed by vacuum distillation.  Little or no sulphuretted hydrogen is evolved and the reaction product contains phosphorus and sulphur in substantially the same proportions as in the phosphorus sulphide used.  It is a dark orange viscous oil soluble in mineral lubricating oils.  The reaction ingredients are preferably first mixed with an inert solvent, such as a mixture of substantially saturated aliphatic hydrocarbons.  This may conveniently be the same as the motor oil which is to be stabilized against oxidation.  Monocyclic terpenes such as dipentene and olefinic hydrocarbon terpenes such as myrcene react in a different manner with considerable evolution of sulphuretted hydrogen, the formation of much insoluble sludge and a viscous cloudy oil low in phosphorus and sulphur and not completely soluble in mineral oils.

Title: Improvements in internal combustion opposed-piston engines
IPC: F01B7/14
Filed: 1943-08-27
Abstract: 564,691. Opposed piston internalcombustion engines. FORD MOTOR CO., Ltd. Aug. 27, 1943, No. 14050. Convention date, Sept. 12, 1942. [Class 7 (ii)] An internal - combustion opposed - piston engine has an integral cast block providing at its end parts bearings for a pair of inter-geared crank-shafts, a detachable head including valves mounted therein being secured along the middle line of the block. In one form, the'integral block 11 includes four cylinders 12 with waterjackets 13 and has flared portions 14 forming crank-shaft housings which are completed by members 15. The cylinders have each a pair of opposed pistons 18 connected to two crankshafts 20 carrying herring-bone pinions 21, both engaging a central drive gear 22 connected by a spider 24 to a shaft 23. The spider also carries a pinion 25 driving the gear 26 on camshaft 27 which operates inlet valves 28 and exhaust valves 29 mounted in a head bolted to a seating 16 on the block. A plate 30 gives access to the valves. To prevent oil leaking from the cam-shaft into the cylinders due to the manifold vacuum, channels 34 lead from the exhaust ports into recesses 36 in the valve guides, thus maintaining, pressure in said recesses. The valves are as described in U.S.A. Specification 2,235,871. The gearing is enclosed in a front housing 38 and shaft 23 is connected ,to transmission 39. The generator and starter are preferably attached one to each crank-shaft housing as at 41, Fig. 1. The keyed end of the crank-shaft receives a direct drive distributer. Vibration is reduced by a flexible coupling between crank-shaft 20 and pinion 21. For this purpose a plate 61 on the crank-shaft carries four segmental dogs engaging between corresponding dogs 63 of a spider plate 64, the dogs 63 being keyed to the pinion 21. Springs 66 are arranged to cushion a limited movement between the dogs. The outer surface of the spider plate which is urged outwardly by a spring 70 is engaged by a friction plate 68 keyed to the plate 61. The torsional flexibility permitted by springs 66 is positively limited by the dogs arid vibration between the dogcarrying parts is damped by the friction plate. The cam-shaft gears 25, 26 serve as an oil pump. In a modification, Fig. 9, the main block is extended to remove the seating surface 316 from the hotter parts of the engine. The valve assembly 328 is secured by threaded retaining- ring 336. In another modification, Fig. 7, the valve housing is formed integral with the cylinder block and the removable head 117 is secured to a part-cylindrical seat 116. By ' varying the inner surface 129 of the head, different compression ratios may be obtained. The valves in this form are parallel to the cylinder axes. Specifications 553,893 and 558,222, [Group XXXV], are referred'to.

Abstract: 759,152. Fire-extinguishing. PYRENE CO., Ltd, May 17, 1954 [May 19, 1953], No. 14074/53. Class 47 [Also in Group XXVIII] A fire-extinguisher comprises a bottle for a fire-extinguishing medium stored under a high pressure produced by forcing gas into the bottle through an inlet opening, controlled by a filler plug which is constructed so that while in position but not fully home it will allow the gas to be forced into the bottle and when fully home will seal the inlet opening and retain the gas, and which embodies a pressure-indicating device. Liquid is poured into the bottle 6 and the plug comprising a neck 5 partly, screwed into a bush 4. Gas is then forced in through grooves 34 and the collar screwed home against a washer 36. A metal bellows 12 extends from the collar to a cap 14 from which extends a plunger 16, which by the pressure in the bottle on the cap 14 is forced against the action of a compression spring 20 through an aperture in an inner plug 8 screwed into the collar. The protruding end of the plunger indicates that sufficient pressure exists to eject the liquid, e.g. at least 50 lbs. per sq. inch. When the pressure rises sufficiently high to endanger the bottle, e.g. 850-900 lbs. per sq. inch, a diaphragm 26 bursts and liquid passes out through a, bore 24 in the cap, a bore 28 in the plunger, lateral openings 30 in the plunger, and holes 10 in the inner plug 8, the plunger then being retracted by the spring.

Title: Improvements in or relating to air compressing systems or apparatus
IPC: F04C29/02
Filed: 1943-08-30
Abstract: 567,510. Rotary compressors. CLAYTON DEWANDRE CO., Ltd., and RODWAY, J. Aug. 30, 1943, No. 14125. [Class 110 (ii)] An outwardly-sliding vane compressor delivers air to a reservoir through a filter and oil separator, for use in braking, steering and other purposes on vehicles, and has valve means to maintain the supply of sealing and lubricating oil to the compressor under control of air pressure (a) directly from the compressor, or (b) from the reservoir. The compressing system includes an air leak for the purpose of allowing the pressure in the reservoir to fall when no demand is made upon it, thereby enabling 'the compressor to re-charge the reservoir. The compressor is of the type described in Specification 563,454, having radial vanes 1 in an eccentric rotor 2 on a shaft 3, with spring-loaded end-sealing plates 7 which do not rotate. Cam rings 12 cause outward movement of the vanes. Oil seals 15, 16 are provided. Lubricating oil passes through an inlet F, filter 17, and passages 18, 19, leading to the shaft bearings. Oil-laden compressed air passes through a filter 22, and the cleaned air is led upwards through a passage 23 past a non-return valve 25 into conduit G leading to the reservoir. When the latter is fully charged, air pressure unseats a valve 26, presses on a piston 27 causing a piston-rod 29 to open a valve 30 to allow the air to escape from a chamber 24 to atmosphere through ports 31, 32. The space behind the piston has a leakoff passage leading to atmosphere, and is regulated by a needle valve. A spring-pressed valve may be included, to raise the leak-off pressure. The valve 26 is opened against the action of a bellows device 37, which, as the air pressure in the reservoir falls, re-seats the valve 26 and cuts off the piston 27. A spring 38 returns the piston and allows the valve 30 to re-seat so that compressed air from B can again pass the non-return valve 25 to re-charge the reservoir.
