Abstract: 324,078. Guggenheim, C. July 17, 1928. Divided on 324,060. Kinematograph apparatus.-In projectors comprising two or more lenses having a common shutter for simultaneously projecting colourrecord images, the shutter is so constructed and arranged that obturation is effected by a single shutter section having parallel leading and trailing edges, movements of the shutter being such that these edges remain parallel to themselves and the section passes completely through the beam. As shown the beam from a lamp house 7 passes to a three-picture gate 4 by way of a cylindrical lens 8, a mirror 9, and a second mirror 10, a cylindrical shutter 6, having two blades with parallel edges 50, being provided around the mirror 10, and being rotated so as to make one turn per picture shift. The mirrors are carried by brackets 91 angularly adjustable in arms 93 extending from a carrier 92. The images are projected in superposition by lenses 1, 2, 3, prisms 11, 12, and a glass block 13; the film is fed one picture at a time, and a rotary filter disc 5, having filters so arranged that each image is projected through a filter 8 of its appropriate colour in each of its three positions, is housed in a casing 61. The mechanism is driven from a motor through belt pulleys 63, 64, and the gear train comprises a shaft 71 driving the shutter shaft 54 through bevel gears 72, shaft 73, skew gears 74, shaft 75, skew gears 76, sleeve 77, and bevel gears 78. The filter disc is mounted on a shaft 81 within the sleeve 77, and is driven at three times the speed of the shutter; it may be constructed as described in Specification 323,218 so as to permit the use of the projector for monochrome projection, its shaft 81 being connected to the sleeve 77 by a coupling 80, which may be disconnected during monochrome projection. The form of the shutter may be modified, and it may consist of a single reciprocating member. Specification 2136/14 also is referred to.

Title: Refrigerant compressor control
IPC: F25B31/02
Filed: 1965-03-01
Abstract: 1,067,395. Compressors. LENNOX INDUSTRIES Inc. March 1, 1965 [Oct.19, 1964], No. 8662/65. Heading F1N. [Also in Division G3] In a hermetically sealed refrigerant compressor unit (10), Fig. 1 (not shown), in which the compressor (18) and its driving motor (44) are mounted in an inner shell (50, 20, 26) itself mounted in a sealed outer shell (12, 13), an unloading device (86) is disposed within the outer shell and is operable to direct some or all the compressor output to the space between the inner and outer shells. The unloading device (86) is controlled by a pilot valve (88) operated by a thermostat or by suction pressure. In the inoperative position of the pilot valve (88) a conduit (93) connected to the unloading device (86) is subjected to the discharge pressure communicated thereto through the valve (88) and a conduit (92) leading to the discharge manifold (78). The discharge pressure in the conduit (93) urges a valve member (109), Fig.3, (not shown) into engagement with a seat (111) whereby the gas discharged from the cylinder (30C) passes through a passageway (77) and conduits (104, 108) to an annular muffle chamber (78a) (shown developed in Fig.3) which communicates through an opening (98) with the discharge manifold (78) which has an outlet (102). Operation of the pilot valve (88) causes connection of the conduit (93) to suction pressure in the space between the inner and outer shells whereby the valve member (109) moves away from the seat (111) and the gas discharged from the cylinder (30C) passes through the conduit (104) and an outlet (106) to be returned to the suction space between the inner and outer shells. The compressor (18) has four radially disposed cylinders, two of which (30A, 30C) are provided with unloading devices (86), (86') and hence one quarter or one half of the compressor output may be unloaded. Gas enters the outer shell through an inlet (82) and flows through apertures in a mounting flange (27) before entering the inner shell through an aperture (51) to cool the motor (44) and pass to openings (84) in communication with the cylinder suction valves.

Organic waxes specified are beeswax, paraffin wax, carnauber wax, ceresine, coca butter, ozokerite, candelilla, spermaceti, hydrogenated castor and palm kernel oils, montan, microcrystalline waxes, lanolin alcohols and waxes from the Fischer-Tropsch synthesis. Numerous examples of cosmetic solvents and colouring agents are given. Flavours and/or perfumes may also be added. In a typical Example (1) a lipstick was made by melting and mixing a siloxane carnauber wax copolymer, a liquid dimethylpolysiloxane, cetyl alcohol, isopropyl myristate and a red dye, until a homogeneous mixture resulted, and the mixture was then poured into a mould and cooled. Uses: for making a lipstick rouge, chapstick, eyebrow stick, mascara, epilating wax, solid perfume and styptic crayon.

Abstract: A thixotropic emulsion comprises a stable suspension of one or more water-insoluble alkaline-earth metal salts in an aqueous vehicle, up to 5 per cent of a water-soluble citrate of an alkaline base and up to 40 per cent of one or more oils, fats or water-insoluble material or artificial resins.  Citrates of alkali-metals, ammonia, amines, alkanolamines and quaternary ammonium bases may be added as such or formed in situ from citric acid and the base.  The fat or oil may be of mineral, animal or vegetable origin and includes hydrogenated fats and numerous examples are given.  Specified resins, which may be added as a solution in an organic solvent with the addition of emulsifiers, if desired, are oleo-resins, e.g. benzoin, gum resins, e.g. myrrh and synthetic resins, e.g. vinyl, phenol-formaldehyde and urea-formaldehyde.  The suspension of the alkaline-earth metal salt in respect of which reference is made to Specification 635,559 may be prepared by agitating a solution of a water-soluble sulphate, borate, chromate, phosphate, carbonate, silicate, aluminate, molybdate or malate with a solution of a water-soluble alkaline-earth metal salt at any temperature, preferably approaching 0 DEG C. and then concentrating by filtering, pressing or hydroextracting, with or without washing.  Additional finely-divided inorganic salts of Al, Bi, Cu, Fe, Ni, Ti and Zn may be added.  Ph range extenders such as water-soluble carbohydrates or aliphatic polyhydroxy alcohols may be added.  To increase or decrease the conversion time of the emulsion from a rigid to a free-flowing state phytates and ortho, meta and pyrophosphates and their polymers and polymers of metaphosphoric acid may be added.  The emulsions are applicable to various arts but particularly to pharmaceutical and therapeutical preparations (see Group VI).

Title: Improvements in or relating to looms
IPC: D03D45/50
Filed: 1963-03-05
Abstract: Immediately a bobbin has been transferred into the shuttle, a suction-type tip bunch stripper operates on the next bobbin in the magazine.  The stripper is brought into action by bringing a projection on it into the path of a projection on one link of a continuously-driven endless chain; as the link passes round a sprocket at the inner end of its travel, the projections disengage, leaving the stripper in engagement with the tip of the bobbin.  When the projection on the chain leaves the sprocket, it encounters another projection on the stripper, whereby it pushes the stripper away from the bobbin to its position of rest.
