Abstract: 960,121. Mechanically treading grapes. F. J. CLARKE, and J. H. SMITHES. Jan. 11, 1962 [Jan. 12, 1961], No. 1414/61. Heading A4C. In mechanically treading grapes and aerating and stirring the expressed juice, the grapes are placed in a vat 1, Figs. 1 and 3, and squeezed by a platen 16, e.g. provided with perforations 61, secured, together with stirring paddles 55 and 56, to a vertical shaft 15, which is oscillated, vertically and rotatably, by mechanism mounted on the base 4 of a carriage 3, which can be traversed, continuously or intermittently, e.g. in two directions at right angles to each other, across the open mouth of the vat. Two parallel tubular axles 5 may pass through the base 4, so that the carriage 3 may be slid to and fro, by hand, along them. These axles may carry doubleflanged wheels 6 engaging rails 2 along the top of the vat. The carriage may be moved, to and fro, along the rails by a chain-andsprocket drive 57, actuated by a handle 58. Two platens (not shown) reciprocating vertically 180 degrees out of phase may be provided. In an alternative construction, the wheels may be mounted on the carriage to engage a circular track around the mouth of the vat.

Title: Improvements in variable-speed power-transmission mechanism
IPC: F16H47/10
Filed: 1938-01-15
Abstract: 509,763. Hydraulic power transmitters. SINCLAIR, H. Jan. 15, 1938, No. 1417. [Class 69 (ii)] [Also in Group XXIV] A power transmitting mechanism comprises . a hydraulic torque converter 2, which is provided with an auxiliary coupling device 15 for a direct drive, in combination with a mechanical change - speed gear 4 srranged between the driving engine 1 and the torque converter and adapted to be changed while running. A hydraulic coupling 3 is arranged between the engine and the driving shaft 5 of the gear 4 which comprises an epicyclic train, the planets being carried by the shaft 5, the annulus 7 being connected to the driven shaft 9 which is also the power input shaft of the converter, and the sun 8 being adapted to be held stationary by an electromagnetic brake 13 or clutched to the sun 7 by an electromagnetic. clutch 12. The shaft 9 carries the impeller 14 of the torque converter, the turbine element 36 of which is coupled to the final driven shaft 16 and the reaction element 37 being carried by the casing 38 which is free to rotate in a forward direction but prevented from backward rotation by a Legge synchro-coupling , 39-42. The direct drive coupling device 15 is also a Legge synchrocoupling of the type described in Specification 410,083, [Group XXIV], and comprises a locking sleeve 30 operated by a solenoid 56 through a lever 33 and pins 31. The ratio of the higher to the lower speed of the mechanical gear is substantially that of the speed ratio:of the.torque converter when the torque ratio is 1 to 1, for example about 1.5/1, and is controlled together with the direct drive coupling 15 by a switch 45 to enable the converter to work under conditions of maximum efficiency as long as possible. In starting from rest the lever 45 is moved from neutral to position Gl in which the sun 8 is held and the mechanical unit put into high gear, the speed of the output shaft of the converter increasing until the torque ratio thereof, of output to input, is about 1.5 to 1. The system is then changed to direct drive throughout by moving lever 45 to G2, the clutch 12, 11 being energised and the coupling 15 engaged on slowing down of the engine. The engine and driven shaft can then be speeded up in the direct drive until an overdrive is desired which can be obtained by moving lever 45 to G3 and changing the mechanical gear to its high ratio whilst maintaining the converter in direct drive. The mechanical change-speed gear may be a planetary gear with a triction clutch and brake electromagnetically operated as shown or it may be of the synchro-self-shifting type with positive gear-selecting clutch and stop devices as described in Specification 486,589.

Title: Planographic printing plate
IPC: B41N3/03
Filed: 1957-01-14
Abstract: 852,468. Printing surfaces. TICKNER, A. (Columbia Ribbon & Carbon Manufacturing Co. Inc.) Jan. 14, 1957, No. 1422/57. Class 100(2) A process of making a planographic printing plate comprises applying to at least one side of a sheet of paper having sufficient wet strength to withstand printing stresses under moistened conditions a solution of a water soluble starch glycolate compressed in film forming concentration, drying the film to form a continuous coating of a water soluble starch glycolate and subsequently treating the coating to render it insoluble. The starch glycolate compound may be sodium or ammonium carboxymethyl starch, and the insolubilizing solution may be a solution of a salt or salts of a divalent or trivalent metal. Preferably the metal salts solution comprises 3 % by weight of copper sulphate, 1 % aluminium sulphate, ¢% ferric chloride, ¢% chromium trioxide, and 95 % water. The sodium or ammonium carboxymethyl starch is applied in solution at a concentration of 2% to 6% by weight. Mineral filler, such as china clay, is suspended in the starch glycolate solution and a small quantity of a plasticiser, such as glycerine, can be added to render the resulting film more pliable. Wet strength may be added to the paper foundation by the inclusion during manufacture of a urea-formaldehyde resin or a melamine-formaldehyde resin. The plate may be provided with an oleophilic image (a) prior to the application of the coating, (b) after the application of the water soluble starch glycolate compound but before it is rendered insoluble or (c) after the coating compound has been rendered insoluble. In the latter case the image may be formed photographically after coating the plate with a lightsensitive film. In an example, paper having a weight of about 60 lbs. per ream, and impregnated with a melamine-formaldehyde resin was coated with a composition made up of 3 parts by weight of sodium carboxymethyl starch, 150 parts water and 15 parts of china clay. The coating was dried and the coated paper then washed with a solution of 3% by weight of copper sulphate, 1 % aluminium sulphate, ¢% ferric chloride, ¢% chromium trioxide and 95% water. After drying and calendering the plate was coated on its rear surface with a 20% solution of polystyrene resin in ethyl acetate to form a water impervious film. The plate was then provided with a printing image.

Title: Bleaching process using hydrogen peroxide as bleaching agent
IPC: D06L4/18
Filed: 1947-01-24
Abstract: Articles are bleached by damping them in a bath containing hydrogen peroxide, preferably 4 to 8 per cent and at a temperature up to 50 DEG  C., then treating them with steam in a separate chamber, whereby their temperature is raised to 90-95 DEG  C. in about 1 minute, and finally adding an alkaline catalyst to effect decomposition of the hydrogen peroxide; the supply of steam is continued for about the 30 seconds needed to decompose the peroxide and for a further minute thereafter to complete the bleaching; the catalyst may be gaseous ammonia or a finely divided solid or liquid material, e.g. sodium carbonate.  Articles so treated may be flax, hemp, jute, straw, grass, wool, cotton, feathers, sponges, hair, felt, silk, horse-hair or leather.  The correct degree of bleaching may be obtained by using a measured quantity of hydrogen peroxide of known concentration, or by removing the excess before steaming, e.g. by centrifugal separation, pressing or dripping.  The process may be continuous.ALSO:The Specification as open to inspection under Sect. 91 states that articles such as bones, horn and ivory may be bleached by a two-step process, the articles being first damped with hydrogen peroxide and then brought into contact with an alkaline catalyst for the decomposition of the peroxide.  The bleaching bath may contain from 4 to 8 per cent of hydrogen peroxide, stabilised with phosphoric acid, and the articles are soaked for a very short time, e.g. 1 to 2 minutes, at a temperature up to 50 DEG  C.  The main bleaching process is then effected in a closable vessel, the temperature of the articles being raised to 90 - 95 DEG  C. with steam.  The alkaline catalyst is then introduced, which may be gaseous ammonia or a finely atomised liquid or solid compound, and bleaching is effected in a very short time.  The process may be continuous.  This subject-matter does not appear in the Specification as accepted.
