IPC: G03B27/52
Abstract: 1,052,838. Photo-copying apparatus; electro-photographic apparatus. AGFA-GEVAERT A. G. Oct. 1, 1965 [Oct. 24, 1964], No. 41773/65. Headings G2A and G2H. In a photo-copying apparatus, an illumination aperture 16 in a reflector 15 carried by a support 8 is movable past a transparent support plate 2 on which an original, e. g. a page of an open book, is placed, the original being illuminated by tubular lamps 13 and 14 also mounted on the carriage 8 which further carries a first-mirror mirror arrangement 12 to reflect the normal scanning beam parallel to the scanned area. Further reflection by a mirror arrangement 10, 11 on a carriage 9 reverses the beam so as to allow it to pass through a rotationary lens 4 onto a moving copy sheet 24, the optical distance of successive scanned areas of the original from the area of the sheet 24 being maintained constant by movement of the mirrors as the illumination aperture moves. The carriage 9 is moved at half the speed of the carriage 8 by means of a wire 47 and pulley 48, one end of the wire being attached to the carriage 8 and the other end to an eccentric 49a, rotation of which effects the focusing of the optical system. When a sheet 24 is inserted into slot 1a, it is traversed past the exposure point by continuously rotating rollers. The leading end of the sheet closes a microswitch 45a just before reaching the exposure point, the switch operating a magnetic coupling 41 to reel in wire 35 and hence move the carriages 8, 9. Variations in the ratio of the speed of the sheet 24 to the speed of the carriage 8 correspond to variations in the optical reproduction scale selected. The above exposure apparatus may be used in connection with electro-photographic copying apparatus and apparatus for the execution of a silver salt diffusion process.

IPC: F16K5/06
Abstract: 1,054,270. Valves. A. M. MOEN. June 27, 1963 [June 27, 1962], No. 25709/63. Heading F2V. In a rotary spherical fluid control valve, the ball is located within a removable insert of resilient material, e.g. rubber or P.T.F.E., through which an integral operating stem projects. The assembly formed by longitudinal insertion of the integral handle, stem and ball assembly 31 through retainer cap 12 into the rubber valve seat insert 21 is sealingly retained within valve body 10 by compression of the insert flange 27 to the body 10 by the cap 12 attached thereto by screws 13 and 14 which also act as stops for the limiting position of handle 11. The flange 27 is moulded for retention within the square cap 12 to enable disassembly from the body 10 upon rotating the cap 12 by a wrench, with opposite corner areas of the flange cut away for clearance for the screws 13, 14. The cap 12 may be replaced by a flat plate interlocked with the insert by downwardly projecting fingers or by projections extending upwardly from the insert into the plate. Alternatively, the insert (Fig. 16, not shown) may be assembled around the ball and stem assembly in two halves with 0-ring seals, for the stem, within an internal groove 71, and between the insert and valve body bore, within groove 69. The inserts may also be slit along one side only for assembly about the ball and stem. The ball and stem has a cross passage and an intersecting axially extending passage enabling the insert assembly to be utilized on bodies having either straight-through or 90-degree passage intersections. The passages may be of circular or elliptical cross-section and with the latter, with the major axis parallel to the stem axis, a greater area of flow is provided. The insert (Fig. 14, not shown) may be longitudinally tapered.

Patent GB-1095601-A (GB)
IPC: F25B31/02
Abstract: 1,095,601. Compressors. CARRIER CORPORATION. April 30, 1965 [July 27, 1964], No. 18336/65. Heading F1N. An hermetically sealed compressor 1 driven by an electric motor 8 comprises a crank-case compartment 10 and a motor compartment 7 separated by a partition 4 having a lubricant overflow passage 62 which allows excess lubricant collected in the crank-case 10 to be forced by the pressure therein into the motor compartment 7 where some is entrained with the suction gas flowing therethrough. The pressure in the crank-case 10 is always higher than in the end of the compartment 7 adjacent the passage 62 since suction gas admitted to the motor compartment 7, through an inlet 49, decreases in pressure after flowing through restricted passages in the motor 8 to the end adjacent the passage 62 which communicates with the compressor suction chamber 30. The pressure of suction gas at the inlet 49 is communicated to the crank-case 10 through a passage 60 in the driving shaft 20. The passage 62 may contain a variable orifice device, Fig. 4 (not shown) which automatically increases the effective area of the passage 62 when lubricant is returned to the crank-case 10 during compressor shutdown. Compressors constructed as above, when provided with common inlet and outlet conduits do not experience lubricant starvation as a result of lubricant collecting in an idle compressor, especially if the crankcase of each compressor is interconnected.

Abstract: 1,113,416. Sectional boilers. "WEMAC". 9 Aug., 1965, No. 34032/65. Heading F4A. A boiler 10 is composed of rectangular sections 11, bolted together, which in their lower part define a water enclosed firebox 12 and in their upper part two or more horizontal flue chambers 15 leading to a chimney (not shown). Water to be heated circulates through headers 16, 41 and passages 17 defined by the hollow cores of the sections 11. Gases from a forced or natural draught burner (not shown) pass along the firebox 12 and though a series of uptakes 21 and passages 21<SP>1</SP> and 21<SP>11</SP>, defined between adjacent sections 11, to horizontal passages 26, and then through a slidable apertured baffle plate 25 to the flue chambers 15 and the chimney. The baffle plate apertures 25a vary in size throughout the length of the boiler 10 to produce the desired gas flow distribution depending on the type of burner used. Adjacent sections 11 are formed with grooved lands 30, 31 packed with asbestos rope to provide a gastight seal. In modifications, the baffle plates may be vertically disposed between the horizontal passages and the flue chambers (Fig. 6, not shown), and the flue chambers may be situated at the sides of the sections, the gas uptake passages being located in the centre (Fig. 7, not shown).
