Title: Improvements in and relating to moisture absorbing devices for jars and other receptacles
IPC: B65D51/30
Filed: 1924-10-06
Abstract: 233,231. Alexander, A. E., (Panay Horizontal Show Jar Co.). Oct. 6, 1924. Internal fittings; special shapes.-In jars and other receptacles having stoppers or covers provided with moisture absorbing devices, an absorbent pad in a holder C, Fig. 2, is removably held in place by a perforated casing H detachablv secured to the cover 3 by means such as a bolt 13 which passes through substantially central apertures in the casing and holder. To adapt the device for adjustment to different positions on the cover, the bolt 13 and nut 15 co-operate with a slot 14 in the casing H. The pad C, comprising a mixture of asbestos, charcoal and calcium chloride contained in a foraminous casing, rests betweeen ribs on the cover 3 and pressed-out lugs 22 on the casing H, the arrangement permitting air to circulate behind and in front of the pad. As shown, the cover 3 which is hinged to a metal fitting 1 on a horizontal confectionery jar A is held closed by a spring 5 and is provided with a flap 9 which prevents spilling of the contents when the jar is opened. In a modification, spring arms 24, Fig. 5, clip the holder K to the hollow stopper S of a vertical jar J, the absorbent pad Q being secured thereto by a bolt 28 and nut 33. A tray 27 prevents any particles that may drop through the perforated sides 25 of the pad casing from reaching the contents of the jar.

Abstract: 603,253. Photographic projection-printing apparatus. DRUCKER, S. Sept. 13, 1945, No. 23674. Convention date, Sept. 18, 1941. Drawings to Specification. [Class 98 (i)] A projection printer which has a displaceable light filter of a non-actinic colour is characterised by the use of an opaque support for the light-sensitive material, which support is of the same non-actinic colour as the filter. The opaque support may be constituted by the baseboard of the printer, or by an enlarging easel. The filter may be red, and focusing may be effected with the red light, which provides a visible image on the support of the same colour. During exposure, reflex fogging which might occur if a white baseboard was used, is prevented.

Abstract: 518,078. Controlling valves &c. UNITED GAS INDUSTRIES, Ltd., SMITH, E. W., CHARLES, A., and CHRISTIAN, A. J. Aug. 11, 1938, No. 23717. [Class 27] Valve contral.-Valves, switches &c. for gas or like meters are controlled by two or more mechanisms one of which is a master control. Fig. 1 shows a gas valve a swinging about a shaft c to the outer end of which is fixed a disc f which is pulled by a spring j so that the valve tends to open. Loosely mounted on the shaft c are independent arms g, i which engage pins f<1>, f<2> projecting from the disc f. A spring h coiled around the shaft c engages the pin f<1> and a screw g<2> on the arm g, and tends to turn the disc f clockwise when the arm g moves clockwise, and to open the valve. The arm g is turned clockwise by a coin mechanism cum metering mechanism disc k, and the arm i bears against the pin f<1> of the disc f to prevent opening of the valve till a basic rate cam disc l rotates to swing the arm i upward to the position shown in dotted lines. The cam groove in the disc l has concentric portions to allow for payment of arrears. Electro-magnetic operation may be employed, and the master control may be a time control mechanism.

Filed: 1946-08-12
Abstract: <PICT:0639713/III/1> In the production of phosphatic fertilizers wherein crude phosphates are melted with or without other materials, e.g. sand, lime, but not alkali metal compounds, in a rotary kiln and the outside of the kiln wall in the melting zone is cooled to cause a layer of the molten mass to solidify to form the lining, the kiln has a melting zone shaped both to retain a pool of molten material and to cause this pool to change its shape during the rotation. Thus, the melting zone may be non-circular, e.g. elliptical, in cross section, or (Fig. 3) the axis of the melting zone 2 may be inclined to the axis of rotation of the whole kiln.  The melting zone is lined with silica bricks, which may be replaced by a less resistant material near the feeding end 1.  A burner 7, discharge opening 10, and water spray 13 are shown.  The melting zone in this embodiment may be circular or elliptical in cross section.

The monomer or the fusible polymer may be mixed with pigments, fillers and dyes. Specified catalysts are benzoyl, acetyl, acetone and tetrahydronaphthalene peroxides, and the resinate, naphthenate or linoleate of cobalt, manganese or lead.  The moulded products may be used as electric insulators.ALSO:Diesters of a 3 : 6-endoxa-1 : 2-cyclohexanedicarboxylic acid or the 3-hydrocarbon derivative thereof, e.g. methyl and ethyl, and an alcohol of the formula CH2=CR-CH2OH, where R is hydrogen, halogen or a hydrocarbon group, are made by condensing the alcohol and the acid anhydride by heat alone, or in the presence of sodium silicate, or dissolved in a solvent in the presence of benzenesulphonic acid.

Abstract: 1375466 Cooling cables SUMITOMO ELECTRIC INDUSTRIES Ltd 26 May 1972 [28 May 1971 11 June 1971] 25110/72 Heading F4U An evaporative cooling system using either an halogenated hydrocarbon (freon) or sulphur hexafluoride for cooling an electric power transmission assembly, includes means for supplying liquid phase coolant along a cooling path within or in cooling relationship with a conductor of a cable of the assembly, to return to the supply means as liquid and vapour along separate incoming paths or as a liquid/vapour mixture along one or more incoming paths; and a valve device provided to control the flow in the incoming path or paths in response to the amount of one of the coolant phases in the cooling path and/or in said incoming paths. In Fig. 7, the cables 1 having cooling paths 5, are disposed in a steel pipe 6 which forms an incoming path Ra for vapour phase coolant. A return pipe RT forms an incoming path Rb for liquid phase coolant. A float valve SP is provided to separate the liquid and vapour phases. The embodiment shown in Fig. 9, differs in that the float valve enables the vapour phase to return in pipe RT, and the liquid phase in Rb. Both the above embodiments have cooling paths S within the cable, the vapour formed through the cooling of the cable passing through the insulation 3. In the embodiment shown in Fig. 11, the insulation is impervious to the vapour and a control valve FC is provided to regulate the amount of circulating coolant flow in proportion to the amount of vapour phase coolant.
