Title: Improvements in or relating to the purification of gases by cooling
IPC: F25J3/02
Filed: 1922-07-22
Abstract: 184,787. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. Aug. 13, 1921, [Convention date]. Separating gaseous mixtures by liquefaction and solidification.-In the purification or drying of air or gases by cooling in heat-exchange apparatus, rime or solid deposit formed on the walls of the tubes is detached by temporarily reversing the direction or flow of the air or gas to be cooled so that the incoming warm air &c. meets first the parts of the tubes coated with rime &c. The detached rime falls by gravity, or is blown by the current of air &c., to a chamber at the end of the tubes, where it is melted after normal working has been resumed, and serves to cool the incoming air. The invention is applicable to the cooling of compressed air by nitrogen in air-liquefying processes, or to the separation of helium from gases by freezing out solidifiable constituents. The apparatus comprises a nest of tapered tubes A in a casing B fitted with baffles C, nitrogen or other cooling-medium being circulated around the tubes from an inlet E to an outlet F. A multiple-way inlet and outlet cock I arranged at the top of the apparatus is set in normal working so that the air &c. to be cooled enters through a passage 0, and passes through a port T, passage O2 and pipe P to the bottom of the tubes, and leaves the apparatus through a central port V and passage O3. For detaching the rime &c. the valve is set so that the gas to be cooled enters the tubes at the top by the central port and leaves at the bottom by the pipe P. The taper of the tubes facilitates the release of the rime &c., which collects on a grating R and is melted by the incoming air when the normal flow is resumed.

Abstract: 203,639. Haddan, A. J. H., (National Cash Register Co.). June 9, 1922. Dating railway tickets and the like. -In cash registers adapted to print upon a detail strip, a check, and upon an inserted slip, and comprising two sets or lines of type-wheels, arranged one above the other, which are set by key-controlled differential mechanism and are moved against stationary platens, hand-set type-wheels for dates and ledger numbers are arranged on each line of type. The upper line of type-wheels is loosely mounted on a shaft 539, Fig. 13, carried by arms 540 secured to arms 542 pivoted on the shaft 509 and forming parts of a yoke 544. The lower line of typewheels is loosely mounted on a shaft 545 carried by arms fast upon the shaft 509. In each line there are nine amount wheels and three wheels for clerks, departments, and transactions, set from the differential segments of the various key-banks. Date wheels 567, Fig. 14, are mounted on a stud 566 in line with the upper type. and on the shaft 545, and are set by hand-moved wheels 571 which project through the casing and also gear with discs 560 in mesh with the wheels 567. The date wheels are held in alignment by pawls 574. The upper date wheels are carried by an arm separate from the arms 540 and extending beyond the shaft 509 and carrying a roller engaging a cam disc on the shaft 515. This arm carries a lug 800 between which and a lug 801 on the arm 621 is a spring 799 which presses the extension 795 against a stop 798 on the arm 621, thus holding the date wheels in alignment with the other type-wheels. Clockwise movement of the arm 621 causes the date wheels to move with the other wheels carried by the arms 540 against the platen. When the high point on the cam 767 engages the arm 621, the high point on the cam 797 engages the roller 796 and prevents the date wheels moving up with the others. The lower type line is swung by cam and link gear from the shaft 515, an aligning yoke being introduced into the linkage so that the movement causes the yoke to engage the typewheels when free from their setting-wheels.

Title: A new solid synthetic resin material and method of its manufacture
IPC: C08J3/00
Filed: 1955-07-14
Abstract: A solid synthetic resin material suitable for use as an electric insulating material in transformers, high-frequency apparatus, switch-gear, &c., is obtained by forming an emulsion of a normally liquid substance in an irreversibly-hardenable liquid resin of the epoxy or unsaturated polyester type and hardening the resin to form a solid body containing the liquid in unchanged condition finely dispersed therein.  The liquid is preferably a liquid dielectric, e.g. a mineral oil, a transformer oil, a silicone oil or a fluorocarbon oil.  The emulsification of the oil is preferably carried out under vacuum in an atmosphere of a gas of high dielectric strength, e.g. sulphur hexafluoride.  Castings of the material may be encased in a casing made of the resins alone.  Epoxy resins specified are glycidyl ethers of polyhydric phenols or alcohols liquid at 20 DEG  C. and hardenable by admixture with the usual hardeners such as polyamines and polycarboxylic acids and their anhydrides, ethers of phosphoric acid and Friedel-Crafts type catalysts.  Polyesters of glycols and unsaturated dibasic acids copolymerized with vinyl-type monomers are specified and may be hardened with peroxides &c. Fillers, e.g. mineral or metallic powders or fibres, may be added. In examples an ethoxylin resin liquid at room temperature is mixed with triethylene tetramine and emulsified with a transformer oil containing a non-ionic emulsifier.  The emulsion hardens to a solid when heated at 50 DEG  C. for 4-5 hours.  (2) A transformer oil is emulsified with an unsaturated polyester by means of a "shock-stirrer" rotating at 10,000 revolutions per minute.  1 per cent of methylethylketoneperoxide and 0.3 per cent cobalt naphthenate solutions are added and the material solidified in an oven heated to 100 DEG  C.
