Abstract: 678,800. Filling bottles. BARFORD (AGRICULTURAL), Ltd. May 8, 1951 No. 10791/51. Class 125(ii). [Also in Group XXIX] In a bottling valve in which the liquiddelivery valve opening 11 is formed between an annular valve seat 5 on a vent tube 6, and a sleeve 4 slidable on a supply tube 1 and carrying the bottlemouth seating 12, a valve 9 controlled by movement of the seating 12 shuts off the supply to the tube 1 when the delivery opening is closed in order to prevent leakage between the sleeve and supply tube. Upward movement of the bottle 13 first moves the seating 12 and sleeve 4 away from the seating 5 against the spring 15.

Abstract: 1384624 Dryers for sheet material PAKO CORP 8 March 1972 [15 March 1971] 10836/72 Heading F4G  Individual sheets S (e.g. of photographic prints and film), are transported by a walking beam conveyer 22-29 through a drying chamber 10, 11, heated air being directed on to the upper surfaces of the sheets S. Sheets S are fed into the drying chamber between sponge rubber rollers 15, 16 so driven from the main shaft 21, that the speed of the sheets through the rollers 15, 16 is lower than on the walking beam conveyer 22-29. The excess moisture thus removed drains into the store of sheets awaiting drying. The walking beam conveyer comprises fixed channels 22 and moving channels 23 coated with heat insulating and corrosion-resistant plastics. The moving channels 23 are mounted on a frame 24 supported at slots 24a on pins 28 mounted eccentrically on discs 29 carried on shafts 26 driven through gears 27 by a main drive shaft 21 driven by a variable-speed motor M. Warm air circulation is provided by a blower 31 which maintains a positive air pressure on the top of the sheets S and a partial vacuum on the bottom by drawing air downwards between the channels 22, 23, and circulating the air past heaters 30, through ducts 32 along each side of the drying chamber 10, 11, and via baffles 33 to the upper side of the sheets S.

In the separation of one or more condensible components of a gas mixture e.g., the water and carbon dioxide content of air by cooling in a heat exchanger the latter comprises a plurality of fins or vanes 16, Fig. 1, projecting laterally from a carrier 15 connected at one end 14 to a thermal sink e.g., a known gas refrigerator, the mean temperature of the vane or vanes on which deposition of a component begins being maintained at not more than 20C. below the highest temperature at which deposition can occur and also the temperature difference between successive vanes in the direction of gas flow being not greater than 20C. In operation air enters an aperture 23 of an insulating screen 22 and traverses staggered apertures 17 of a group 18 of vanes 16 which serve to freeze the water vapour content. Dry air at 60C. then traverses a second group 19 of vanes where it is cooled to about -140C. without further deposition and finally traverses a group 20 of vanes where carbon dioxide ice is deposited at a temperature of between -140 and -180C. The wall thickness and hence the thermal conductance of the carrier 15 varies from zone to zone. The so purified air is liquefied by contact with the base 14 and is discharged through duct 21. In a modification an ice depositing set of apertured vanes 35, Fig. 2, carried by tubes 33, 42 surround non- depositing vanes 37 and carbon-dioxide depositing vanes 35 carried by tubes 32, 31, 39.
