Title: Improvements in or relating to the manufacture of desizing compositions
IPC: D06L1/14
Filed: 1949-12-09
Abstract: A desizing composition for textiles comprises amylase from animal and/or bacterial sources, common salt (preferably 20-50 per cent), and one or more vegetable albumin-containing substances, in particular, vetch flour, lupin flour, bean flour, or soya flour.  The composition preferably also contains calcium sulphate, e.g. in the form of gypsum.  In an example, 100 grams of vetch flour and 200 grams of common salt are added to 700 grams of an amylase containing culture liquid of a suitable Bac. Subtilis culture.  In other examples the amylase-containing constituent is degreased pancreatin powder or a paste of pulped pancreatic gland.  In the latter case the paste is mixed with twice its weight of lupin flour and the mixture dried in an air stream.  It is then finely ground and, if desired, degreased with acetone.  The resulting powder is then mixed with common salt and with sufficient gypsum to give the composition a gypsum content of about 25 per cent.  Specification 682,878 is referred to.

Abstract: 661,122. Crackers. SMITH & CO., Ltd., T., and HARRISON, E. Dec. 5, 1949 [Dec. 8, 1948], No. 31757/48. Class 132 (i). A machine for making paper crackers comprises a pair of axially aligned rotating cylindrical formers 33 around which a flat paper pack 95 is adapted to be rolled into cylindrical form 68 by means of said formers as they are mechanically rotated in unison and a mechanism, including loops of string 69, operating synchronously with the formers 33, for forming two waists simultaneously in the paper cylinder by crimping of the paper, said formers supporting the paper cylinder 68 at opposite ends during the waist crimping operation and at least one of them being subsequently displaced endwise to release the waisted cylinder. The formers 33 reciprocate between a position at the edge of the plate 70, where the paper pack is picked up and held on the former by pneumatic or other means, and a position above slots 67 in a table 66 where waists are formed in the cylinder, which is rolled as the formers rotate in passing from one position to the other. The waist crimping is effected by two pairs of string-connected arms that are projected through slots 67, the arms of each pair being then swung in opposite directions so as to loop the associated string 69 around' the paper cylinder. The finished cracker is released after waisting and ejected by levers, two examples of which are described. The formers and the string-carrying arms may be moved inwardly as the waists are formed to consolidate the centre and compensate for the shortening of the cylinder. A hopper or the like may be used for feeding a " centre " into the cylinder as it is rolled. All the various parts of the machine are connected with an electrically driven mains shaft by linkages and cams, the cams being arranged to cause the operations in their correct sequence. Specification 457,422 is referred to.

Title: Improvements in or relating to the production of crystalline anhydrous sodium metasillicate
IPC: C01B33/32
Filed: 1934-11-05
Abstract: Crystals of anhydrous sodium metasilicate are obtained by forming a solution of sodium metasilicate containing say at least 50 per cent of metasilicate at temperatures above 72 DEG  C., and heating the solution, say to 90--120 DEG  C. or above.  By stirring and evaporating continuously all the water may be removed and a dry product be obtained directly.  The metasilicate solution may be obtained by treating a water-glass solution with caustic soda, or by treating ground silicate of soda glass or finely ground silica with caustic soda in the presence of added water.  By having present in the metasilicate solution substances such as sodium carbonate, sodium hydroxide, other alkaline salts, or a soap, mixtures of crystals in intimate association may be obtained, and the additional substance may combine with any residual water.  An example is given of the production of a mixture of sodium hydroxide monohydrate and anhydrous sodium metasilicate.  The products are suitable for use as detergents.

Title: Data processing system
IPC: G06F13/38
Filed: 1969-06-25
Abstract: 1,260,341. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 25 June, 1969 [11 July, 1968], No. 31976/69. Heading G4A. In a data processing system, an I/O channel uses a control unit for communication with peripheral devices, the control unit having at least two parallel interfaces adapted to be operated either separately or jointly for connecting the peripheral devices thereto, the control unit receiving data and commands from the system, recognizing that a message is directed to it, decoding commands received for specified peripheral devices connected to it, transmitting commands to a specified peripheral device, setting up data paths between the peripheral device and system, and signalling the system that a requested task has been completed by the peripheral device. A System 360 selector (or multiplexer) I/O channel is connected to a series of control units, each control unit including two transmission channel sections (each connected to up to 16 peripheral devices) and a common portion. Each transmission channel section includes an address assignment register (specifying the address of the section and loadable from a connected peripheral device or manual switches), a device address register, command register and 2-bit transmission control register (all loaded from the I/O channel), a sense register and a status register (to feed the I/O channel), and two 2-byte data buffers (one feeding the other, and usable for both input and output). The common portion includes a 4-bit common control register permitting the transmission channel sections to operate independently or for either to borrow the input or output data paths of the other from/to the peripherals (as well as its own). Each of these paths may also carry selectively one or two bytes in parallel. A peripheral connected to one transmission channel section of a given control unit may communicate data with a peripheral connected to the other transmission channel section of the control unit via the common portion and the data buffers in the transmission channel sections, provided the commands in the sections are compatible, the system I/O channel not being involved (and being free for other uses) except for starting the operation and transmitting ending status. Data, address, tag, (operation) select, and control lines between the control unit and its peripherals are described in detail, being different from the lines between the control unit and the system I/O channel (which are conventional System 360). The peripherals may include digital processors, A-D converters, magnetic tape units, plotters, displays and communication equipment.

Title: Improvements in and relating to patterned metal stencil screens
IPC: H05K3/00
Filed: 1953-11-20
Abstract: 752,090. Stencils. ROTHSCHILDS CONTINUATION, Ltd., and FREUDENHEIM, H. Nov. 11, 1954 [Nov. 20, 1953], No. 32253/53. Class 100 (2). An all-metal screen stencil is made by first forming a metal stencil part on a temporary support by forming a resist image on the support and depositing a metal foil on the parts left bare by the resist image, a layer of solder is then applied to the free face of the metal foil and after removing the resist, a metal mesh screen is bonded by soldering to the soldercoated face of the foil and the temporary support is removed. The temporary support may be stainless steel, the resist image being formed by photography. The metal foil and the layer of solder are deposited electrolytically. In the Provisional Specification other methods of making metal stencil screens are described. In one, a foil of metal such as copper is detachably deposited on an etch-resistant support and coated with an adhesive. A resist image is formed over the adhesive and the exposed parts of the adhesive and metal foil are etched away. The resist is then removed and the metal foil is made to adhere to a mesh screen by means of the adhesive layer and the temporary support is removed. In another method a foil of etchable metal is soldered to an etch-resistant screen mesh and coated with a photographic layer. The photographic layer is exposed and developed and parts washed away to make a resist image. Those parts of the foil exposed by the image are then etched away. In a further method the openings in a screen mesh are filled by electroplating with an etchable metal which is etched away to form a pattern as before, or alternatively the screen mesh may be formed with a resist image and filled up in those parts which are exposed by electrodeposition. In a further method an image in resist is formed on a support and metal is deposited on the exposed portions. A conductive image is then formed corresponding to a screen mesh pattern and extending over the whole area and further metal deposited. The metal pattern and screen are then stripped off the support together.
