Title: Process for the saturation of lime containing or lime treated sugar juices or syrups by gaseous sulphur dioxide or carbon dioxide
IPC: C13B20/06
Filed: 1932-02-22
Abstract: <PICT:0396136/III/1> The saturation of sugar juices or syrups with gases such as sulphur dioxide or carbon dioxide is effected by introducing the gas into the liquid in a closed boiler kept under pressure.  The pressure may be one atmosphere for the treatment of beetroot juices.  The pressure on the liquid is obtained either by the excess of reacting gas being evolved or by the introduction of inert gas into the closed vessel.  The sugar juices are made alkaline with lime before the treatment.  The process may be carried out continuously in a boiler A, the liquid flowing in from a tank R and a pipe T and leaving through an overflow P and siphon tube U.  The gas enters through a pipe V and is distributed by an inverted shallow pan N having serrated peripheral edges.  A perforated plate X further divides the gas stream.  Excess of gas escapes through a safety valve I. According to a modification the gases are passed from the boiler to another boiler containing liquid through a downwardly extending tube.  The head of liquid in the second vessel puts the pressure on the first.  The liquid in the second boiler may be liquid which has passed from the first by a tube which enters the second vessel at a point below the introduction of the gas.  The liquid passes from the second vessel through a lateral outlet.  The process may also be conducted discontinuously.  The Specification as open to inspection under Sect. 91 comprises also the application of the above process to the treatment of liquids with gases in general particularly to the manufacture of soduim bicarbonate by the Solvay process.  This subject-matter does not appear in the Specification as accepted.

Title: Method of producing electros and the like
IPC: B41C3/08
Filed: 1923-02-24
Abstract: 193,864. Dresdensia Matern-und Stereotypie-Anstalt C. W. Woehler. Feb. 24,1922, [Convention date]. Electrotype; stencils. -- Printing-surfaces are prepared by the following process. A thin layer of a soft resist such as a mixture of wax, paraffin, ceresine, turpentine, asphalte, and graphite, is laid over a metal or other base, and the design is drawn on this with a stylus, the layer being removed down to the background. Metal is then deposited electrolytically so as to form when detached a plate with raised lines. The base should be of a material not attacked by the electrolytic bath, e.g. a lead alloy. When the base is of insulating material, the resist is rendered conducting, the resulting deposit being in the form of a stencil. The mould may be " built-up " by applying wax to the parts of the layer not removed. The deposit is removed by heating. Several plates may be made from the same mould. Reference has been directed by the Comptroller to Specifications 2681/92 and 24567/97, [both in Class 101, Printing other than letterpress &c.].

Abstract: 525,579. Reciprocating-rake conveyers. GIBBS, H. H. Feb. 23, 1939, No. 6058. [Class 78 (i)] In conveyers of the type in which reciprocating racks are connected to driving cranks for conveying hay step-by-step to the top of an incline, means are provided for increasing the stroke of the rake without a corresponding increase in the throw of the driving crank. Fig. 2 shows the rake 7 which is carried by cranks 2, 12 so as to move in a closed curve, propelling the material during the forward stroke and being raised prior to the return stroke so as to miss the material. In the present construction the rake is pivoted at 8 to a lever 3 carried by the crank 2 ; the upper end of the lever being connected by a pivoted rod 4 to a fixed bar 5. In operation, as the crank 2 turns clockwise, it moves the lever 3 bodily towards the right thus advancing the rake. In addition, the restraint of the lever 3 by the link 4 causes the lever to pivot on the crank and the lower end thus moves forward to impart an additional forward movement to the rake. This additional movement is taken up at the upper end of the rake by the member 9 sliding in the bracket 10 attached to the crank 12. A guard 13 prevents the lifted hay from falling back over the top of the rake.
