Title: Refrigeration
IPC: F25J1/00
Filed: 1972-02-23
Abstract: 1374167 Refrigerators L'AIR LIQUIDE SOCIETE ANONYME POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 23 Feb 1972 [26 Feb 1971] 8440/72 Heading F4H A refrigerator comprises two thermal regeneration columns 3, 4, each having a permeable metallic packing which is a poor conductor of heat in the longitudinal direction a capillary tube 6 joining the two lower ends and conduits joining the upper ends through valves 11-14 to the input of compressor 15 and the output of pre-cooler 16, the valves being operated cyclically so that column 3 is connected to the output of pre-cooler 16 while column 4 is connected to the input of compressor 15, or viceversa, alternately. The circuit is charged with a refrigerant mixture having as main constituents a number of substances condensable to the liquid state at the working pressure and temperature of the columns. The charge is compressed and passed first through column 3. The top of the column is hot and the bottom cold so that different fractions of the charge condense along the column 3. A mixture of gas and liquid enters the capillary under pressure and the liquid evaporates, cooling plate 7 and the object 8 to be cooled. The cold vapour passing into column 4 cools the bottom end and vaporizes the liquid condensed in the previous cycle; carrying them back to the compressor. When the greater part of the liquids are removed, the valves 11 and 14 close and those 12 and 13 open to allow the compressed charge to enter the upper end of columns 4 and the process is repeated. The charge may be a mixture of nitrogen, ethylene, propane and butane. Neon, hydrogen or helium may also be present. The metallic filling may consist of stacks of bronze mesh discs, separated at intervals by insulating discs of a plastics material. Alternatively the filling may consist of metal powder, balls, turnings or filaments. The columns are enclosed in an evacuated casing. In another form there is no precooler or valves 11-14. The compressor consists of a double acting piston applying pressure to alternate columns on alternate strokes. Two single-acting pistons may be used instead. Traces of oil from the compressor may enter the refrigerant mixture without harm, the oil merely acting as one of the fractions. Alternatively, a dry compressor may be used.

Filed: 1943-05-26
Abstract: 565,855. Self-tapping screws. AMERICAN SCREW CO. May 26,1943,No. 8441. Convention date, June 25, 1942. [Class 83 (iii)] Relates to self-tapping screws, more particularly for use in synthetic plastic materials, and consists in forms with the crests of threads following a polygonal contour, in crosssection, with rounded corners. The pilot holes in the plastic material have a diameter equal to the maximum diameter A at the root of the threads. Figs. 1 and 3 show a screw of substantially square cross-section with rounded corners 14, the thread being of V-section 16 and of uniform depth. The thread is formed by rolling between dies shaped either to conform to or to produce the polygonal cross-section. In a modification, the thread is cut on the polygonal blank by ordinary circular dies, resulting in the production of flats 23, Fig. 5, at the middles of the sides of the polygon. In a further form, the core may be circular at the bottom of the thread which varies in depth to give the polygonal effect over the crests. The number of sides may vary. A screw of elliptical crosssection may give the effect of two corners. The leading end of the screw is tapered to facilitate entry, the crests in the tapered part being flattened.

Abstract: 1287642 Clocks and watches EBAUCHFS S A 23 Feb 1970 [17 March 1969] 8614/70 Heading G3T An electric timepiece having a first base-plate 4, which carries a vibrator 6 and ratchet wheel 36, and a second base-plate 1, which carries hands and motionwork, is so arranged that the plates 1, 4 may be separately fitted with their respective components and tested before being assembled in the timepiece. The two sub-assemblies are connected by an intermediary which comprised a wheel 58, meshing with a pinion 57 on the ratchet wheel 36, and an elongated pinion 59 which meshes with a wheel 62 of the motionwork. When the subassemblies are separate, the pinion 59 is supported by a bearing 60 in a plate 37 carried by the baseplate 4. The ratchet wheel 36 is driven by a pawl 39, fixed to one arm 11a of the vibrator 6, and is restrained by a second pawl 42 mounted on an adjustable plate 43. The adjustment is carried out using a gauge (49) Figs. 4 and 5 (not shown) substituted for the ratchet wheel 36 and which is kept in a compartment 50 of the plate 4 and becomes available when the plates 1, 4 are separated. Electronic blocks 21, 22 are carried by the plate 4 and are connected respectively to a battery contact plate 20 and to the mass of the movement. The latter connection, via a pin 27 and springs 28, is only made in the inner (rest) and intermediate (date-setting) positions of a setting stem (34) Fig.1 (not shown). In the outer (hand setting) position of the stem (34), the spring 28 is moved inwardly away from the pin 27 by a displaceable member 29. During hand setting, slipping occurs at a friction clutch formed by an arched, resilient washer 69 which urges a wheel 69 against a disc 70 which is rigidly connected to a pinion 71. A similar friction clutch, formed by a washer 63, a wheel 62, and a pinion 64, protects the ratchet mechanism 36, 39 when seconds hand 56 is being placed in position. A wire spring 66 bears on a pulley 67 to act as a brake for the seconds hand.

Class 98(2) An exposed silver halide emulsion, preferably of high contrast silver chloride type, is maintained in contact with a transfer material containing colloidal hydrated copper sulphide as nuclei in presence of a developer containing a silver halide solvent for a time sufficient for transfer and reduction of silver halide in the unexposed areas and thereby production of an image, usually a positive. in the transfer material. The transfer material may contain, additionally, a high energy developer such as hydroquinone or this with metol. a silver halide solvent such as hypo, a restrainer such as a soluble bromide, a colour improver or toning agent such as mercaptobenzthiazole and a plasticizer such as glycerin. In one form of the invention a proportion, or all, of the high energy developer may be incorporated in the negative material. Preferably the copper sulphide for the transfer material is made by precipitation in presence of a protective hydrophilic colloid; thus in example 1 copper sulphate in solution in water with gelatin is precipitated with a slight excess of sodium sulphide and a portion of the suspension with more gelatin and a little formalin diluted with water is coated onto paper and dried to form the transfer material; and this, along with an exposed photographic paper carrying a silver chloride emulsion containing a proportion of hydroquinone equal to one quarter of the silver nitrate used in preparing the emulsion. is immersed in a water solution of caustic soda and sodium sulphite and the two papers in face to face contact are passed.through a pair of nipping rollers and separated after one or two minutes to leave a positive image on the transfer paper. A second example describes an aqueous composition comprising colloidal hydrated copper sulphide, sodium thiosulphate. hydroquinone, glycerin and formalin for preparation of the transfer paper and aqueous caustic soda, sodium sulphite and potassium thiocyanate for the immersion solution, leading to a dark brown or black positive image on the transfer paper.
