Title: Improvements in or relating to circular knitting machines with electrical or/and electronic patterning systems
Inventor: SUTTON JACK
IPC: D04B15/66
Filed: 1968-05-17
Abstract: 1,204,424. Knitting-machines. STIBBE MACHINERY Ltd. 6 May, 1969 [17 May, 1968], No. 23508/68. Heading D1C. Each of a bank of selector levers 130 is either projected into or withdrawn from engagement with the jack butts at a corresponding level by the influence of electro-magnets appropriately energized to cause the appropriate movement of the lever whereby selection of the needles for patterning purposes can be achieved on a circular machine. In a multifeed cylinder and dial machine the selector levers 130 are pivoted at 139 to an arm 133a of a generally U-shaped frame, the two arms 133a, 133b support electromagnets having coil windings 146. A lever 142 pivoted at 147 to the frame is coupled by a link 141 to the selector lever 130. The lever 142 carries a permanent magnet 143 which extends between the electromagnets. Consequently depending on the pattern a suitable pulse to the electromagnets causes the lever 142 to be pivoted in one direction or the other and the toggle connection with the selector lever causes it to project into or be retracted from the path of the butts on the jacks whereby selection is achieved by missing or pressing the jacks inwardly whereby the operative ones are raised to elevate the needles. An arm 150 limits the movement of the selector levers. The electromagnets can be adjusted to vary their effectiveness. Stop bolts 163 can also be used to determine the limits of movement of the lever 142. The series of selector levers each with its control electromagnets can be secured in a block and mounted as a unit on the underside of the machine bed ring 112 surrounding the needle cylinder. A manually operated slide 151 mounted at the bottom of the assembly can be projected to move the jacks inwardly irrespective of the selection and to render all of them inoperative whereby the needles remain in a non knitting position. Suitable programme means supplies pulses to the electromagnets according to the desired pattern.

Title: An improved method of coating surfaces with an aqueous protein composition or photographic silver halide emulsion
Filed: 1952-09-24
Abstract: 721,064. Protein coated paper, film, or fabric. KODAK, Ltd. (Eastman Kodak Co., and Jones, J. E.). Sept. 24, 1952, No. 23968/52. Class 140. [Also in Group XX] Gaseous ammonia is used to cause setting of a layer formed by coating a surface with an aqueous protein composition containing formaldehyde, acrolein or glyoxal. Chilling is unnecessary and the layer may be dried without melting. 0.2 per cent by volume of ammonia in the gas of a fuming chamber is effective, 0.5 per cent is preferred and such gas may be warm. Setting may take place in one second and thus minimize penetration of the aqueous composition into the surface, which latter may be paper, cellulose ester sheeting, glass cloth, metal foil or baryta paper. The protein may be gelatin or modified gelatin, or soy, casein, blood albumin and similar proteins which do not set on cooling alone, and the protein may constitute 20-80 per cent of the protein composition mixed with 80-0 per cent of a polymer such as styrene-butyl acrylate-methacrylamide, acrylonitrile-ethyl acrylate, acrylonitrilebutadiene, styrene-butadiene, styrene-acrylonitrile, styrene - ethyl acrylate, styrene - butyl acrylate or polyvinyl acetate. Examples are mainly directed to photographic compositions (see Group XX), but examples 6-9, 11-16 and 23 are concerned with non-photographic compositions usually containing baryta or for use with baryta coated paper. Volatile amines may replace the ammonia. Specifications 648,927 and 649,545, [both in Group XX], are referred to.

Title: A method of recovering hydrochloric acid from aluminium etching or pickling baths
IPC: C23G1/36
Filed: 1961-07-05
Abstract: Hydrochloric acid and aluminium oxide are recovered from aluminium pickling bath liquors by a three-stage process involving first a distillation to remove hydrochloric acid which may be accompanied by a concentration of the remaining aluminium chloride solution.  The aluminium chloride solution is then admixed with aluminium oxide to form a solid mass which is roasted in the third stage to yield hydrogen chloride and water vapour, which are condensed to give hydrochloric acid.  The dilute hydrochloric acid obtained from the distillation stage may be used for washing out the hydrochloric acid from the vaporous products of the roasting stage.  The aluminium chloride solution may be crystallized prior to admixture with the aluminium oxide.  The crystallization may be effected by the addition of hydrogen chloride from the roasting stage to the aluminium chloride solution.
