Title: Improvements relating to the shaping of leather
Inventor: HOLMES NORMAN LIMON
IPC: C14B1/00
Filed: 1957-10-22
Abstract: 869,285. Dielectric heating of leather. HODGSON & SONS Ltd., RICHARD, and GENERAL ELECTRIC CO. Ltd. Oct. 14, 1958 [Oct. 22, 1957], No. 32916/57. Class 39(3). [Also in Groups VII and XVI] A method of shaping leather comprises the steps of dielectrically heating leather having a moisture content of between 13%. and 21% moisture by weight of air dry leather to a temperature in the range 90 to 60‹C. to render the leather pliant, shaping the leather as required, any loss of water by evaporation from the leather during heating being substantially avoided, and cooling the shaped leather. The leather is heated dielectrically by placing it for a period of from 20 seconds to 3 minutes in an electric field applied at frequencies of up to 100 megacycles. A generator providing a power density ranging between 10 and 100 watts per cubic inch may be used. The electric field is applied between two parallel plates on one of which the leather rests; an air space may be left between the leather and the other plate or a layer of electrically insulating material such as mica may be inserted therebetween in contact with the leather to prevent evaporation of the freed water from the leather. The leather may be coated with a resin or other similar material to prevent loss of moisture. The moulding may be effected in a water-cooled mould or the heating plates may be in the form of a press in which the leather is moulded after heating.

Title: Improvements in semi-conductive alloys and devices utilizing them
IPC: H01L21/24
Filed: 1948-12-21
Abstract: A photosensitive device of the face illumination type (see Group XL(b)) comprises a main body of p- or n-type material, having a thin film of the opposite type material on one face, the photo-voltaic barrier being between the body and the film. Electrical contact is provided by a metallic ring and a metallic film secured to opposite faces of the body, and the metallic film may be made from a heat cured silver paste comprising finely divided silver, a small amount of binder, and a volatile solvent. p  The photo-cell element may be made from a piece of p-type silicon containing an acceptor impurity such as boron, by surface treatment with a donor impurity such as phosphorus, as by sealing the p-type silicon in an evacuated silica tube with some yellow phosphorus and heating.  The body thus treated exhibits a bluish film which has n-type rectification properties. Alternatively p-type silicon containing boron and phosphorus is polished and heat treated in water saturated air or steam and the resulting oxide layer etched off with a hydrofluoric acid solution, boron being removed by selective oxidation from the surface of the material.  Several such treatments may be required to produce an n-type film on the surface.

Abstract: 1435047 Interrupt arrangements HONEYWELL INFORMATION SYSTEMS ITAWA SpA 25 July 1974 [22 Aug 1973] 32994/74 Heading G4A In a computer system in which a plurality of input/output channels are serviced by and receive data from or transmit data to a central processing unit, interrupt wires 47-54 (Fig. 7) are scanned under the control of a counter 73 and a decoder 74, the arrangement being such that (1) an interrupt signal on lines 51-54 results in AND gate 83 being inhibited via OR gates 94, 95 to prevent scanning continuing until the interrupt request is serviced and (2) an interrupt signal on lines 47-50 additionally results in bi-stable 96 being reset to reset counter 73 to zero so that scanning restarts with the first line 47. The interrupts on lines 47-50 relate to service requests whilst the interrupt on lines 51-54 relate to data exchange. The interrupt signal is only passed to an associated gate 109-116 if signal 71 is "1" indicating that higher priority interrupts (121, 122, 23-28, Fig. 6, not shown) are not present. Interrupts on three of these lines (122, 23, 24) are mutually non-interruptable (a control network inhibiting a priority register (57) when an interrupt request exists on the output of one of the leads (56-57, 58) of priority assigning network (65)). Further interrupt requests (on lines 25-28) may also be made non- interruptable. The overall system comprises a memory (2, Fig. 1, not shown) and central processing unit (1) linked via controllers (14-22) to peripherals such as card readers, punches, printers and magnetic disc or tape.

Punching.-Record blanks 28, Fig. 10, in a hopper 25, are separated one by one by a roller 38 and passed to a forwarding band, which moves the blank into engagement with the drum 120, the speed of the band being greater than the speed of the drum. The end of the blank is checked by contact with finger 121 until a pin 124 on the drum enters one of the feed-holes 18, Fig. 1. The blank is then drawn round the drum, being held in contact with it by a spring- tensioned band 122. The blank passes from drum 120 between guide-plates 125, 126 into similar engagement with a second drum 128 which is so spaced that the pins engage the holes 18 in the blank. The drums are advanced synchronously in steps there being a punching operation at each step performed by a row of vertical punches 140 between the drums. The punches are selected by magnets 171 which, when energized release hook levers 175 to engage the ends of levers 168. These levers are lifted by a cam 161 to operate the punches. Those levers whose ends are engaged by levers 175 rotate about the point of engagement to raise the punches. The levers which are not engaged by their associated hook levers move idly about the right-hand end and do not operate their punches. After punching, the record is advanced by drum 128 into a shoot 131 by which it is conveyed to hopper 132. Specification 906,296 is referred to.

Patent GB-344874-A (GB)
Title: Improvements in the manufacture of artificial silk
IPC: D01F2/28
Filed: 1929-11-08
Abstract: Artificial silk of high tensile strength and improved flexibility is obtained by spinning, accompanied or followed by stretching, threads having a tensile strength above 2 gms. per denier, from cellulose esters other than nitrates, and then removing the ester groups completely, or to the extent of at least 10 per cent, from the formed threads.  It is stated that spaces are thereby created between the cellulose crystallites. The threads of high tensile strength may be produced from an acetone solution of cellulose acetate by passing the spun threads through a solvent or swelling agent and subjecting to extension, or alternatively the solution of cellulose acetate may be spun into a mixture of a solvent with a non-solvent or coagulant, or into a swelling agent or a mixture of a swelling agent with a non-solvent or coagulant, and thereafter stretching the threads whilst in the plastic or semi-plastic state.  These high tensile threads are then deacetylated, for example, by digesting with a solution of caustic soda for several hours, whereby they become finer in denier without appreciable loss in strength. Specifications 309,053, [Class 2 (ii), Cellulose &c.], and 344,873 are referred to.
