Patent GB-1223451-A (GB)
Title: Binary arithmetic circuits employing threshold gates
IPC: G06F7/50
Filed: 1968-02-05
Abstract: 1,223,451. Parallel adder. R.C.A. CORPORATION. 5 Feb., 1968 [24 Feb., 1967], No. 5595/68. Heading G4A. A binary adder stage for indicating the sum of at least two bits has a plurality of threshold gates, each of which has inputs receiving in parallel binary signals indicative of a plurality of bits to be added, and at least one output, and are operative in parallel to produce on certain of the outputs a group of binary signals indicative of the binary sum of the applied bits and for producing on at least one other of the outputs a binary signal indicative of a carry bit. Fig. 1 shows a full adder 10 composed of two threshold gates 14, 16, each having three inputs of weight 1 and producing a " 1 " out if a majority of inputs are " 1 " and a " 0 " out if a majority of inputs are " 0." Gate 14 has an output C indicating a carry and an inverted carry output C and gate 16 has an output D. The sum is given by the majority signal on lines C, D, X 1 . A truth table for adder 10 shows that two of lines #C, X 1 , D carry " 1 " when only one of X 0 , X 1 , X 2  is " 1 " or when all X 0 , X 1 , X 2  are "1" and otherwise two of the lines carry " 0." Thus adder 10 acts as a full adder. In a similar manner adder 12 adds bits X 3 , X 4  to sum S to produce a new sum Sa and carry Ca. An alternative circuit (Fig. 3) is a four-bit adder but can be adapted to include more bits. For n bits n threshold gates are required. One of the n bits is represented by the majority signal on an n-line input A and the others by bits on single lines. Each gate receives all inputs with weights of 1. One gate, for instance the leftmost gate, has a bias signal 0 applied with weight 2 [n/2] where [x] is an integer, and the largest integer greater than X if X is fractional. The next gate has a bias signal 0 applied with weight 2 [n/2] - 2 and so on until the [n/2] + 1 gate which has no bias input. The next gate has a bias 1 applied with weight 2, the next a bias 1 with weight 4 and so on to the nth gate which has bias 1 applied with weight 2n - 2 [n/2] - 2. Carry signals are generated by the second, fourth &c. gates counting in the reverse direction, e.g. from the right, and the sum output is provided by the outputs of the first, third, fifth &c. gates and the complemented outputs of the second, fourth &c. On the sum lines [n/2] "1's" represent a "0" and [n/2]+ " 1's " represent a " I." No other possibilities occur.

Patent GB-725142-A (GB)
Title: Improvements in or relating to method and means for magnetic reproduction of pictures
IPC: G03G19/00
Filed: 1952-03-05
Abstract: 725,142. Printing processes. ATKINSON, R. B. March 5, 1952 [April 14, 1951], No. 5745/52. Drawings to Specification. Class 100 (2). [Also in Group XL (b)] Images are reproduced by first forming a magnetic record of the image and then applying a material having magnetic properties to the record in such a manner as to cause the material to be selectively distributed in accordance with the magnetic pattern and thereby to reproduce the image visibly. The magnetic record material comprises a sheet of plastic coated with a magnetic material such as iron oxide, the record being built up by scanning the surface with a magnetic recording head, and the material for reproducing the image visibly comprises a magnetic powder, such as iron, carbonyl iron or iron oxide, which is either dusted over the magnetized sheet or mixed with oil and flown over the sheet, the oil being removed subsequently by a solvent such as carbon tetrachloride or gasolene. The magnetized sheet with its coating of powder may form the final reproduction, in which case the powder is selected to have a colour which contrasts with the sheet. Alternatively the powder may be transferred to another support, such as paper, by coating the paper with an adhesive in the form of gelatine or a sizing and pressing the paper into contact with the magnetized sheet. As a further alternative, the magnetic powder may be coated with a pigment which is transferred by pressing to a final support moistened with a solvent for the pigment. These last two processes permit the magnetic record to be used for repeated reproduction. Colour images are reproduced by combining a plurality of component colour reproductions. In the particular embodiment disclosed, the magnetic reproduction is produced from an original image by apparatus operating in a conventional manner to effect synchronous helical scanning of the original and the magnetic sheet. The original is scanned photo-electrically although the apparatus may also be arranged with a magnetic pick-up head in order to reproduce from magnetic records. It is stated that the recording part of the apparatus may be located at a distance from the image analyser. Specification 686,009, [Group XL (b)], is referred to.

Patent GB-549149-A (GB)
Title: Improvements in or relating to laminated fabric
IPC: D06M17/00
Filed: 1941-05-05
Abstract: 549,149. Artificial silk etc.; compound fabrics. BRITISH CELANESE, Ltd. May 5, 1941, No. 5806. Convention date, May 4, 1940. [Class 2 (ii)] [Also in Group VIII] A fabric containing yarns of a thermoplastic material is rendered suitable for use as a laminating fabric for adhesively uniting the components of a laminated fabric, by applying a plasticizer for the thermoplastic material, ageing the fabric, and then subjecting the aged fabric to a short intensive heat treatment. In making a laminated fabric, the fabric containing the plasticized thermoplastic yarns is assembled with the other component layer or layers of fabric and secured thereto by the application of heat and pressure. The ageing and short intensive heat treatment of the laminating fabric increase the proportion of plasticizer absorbed by the thermoplastic yarns and, when non-thermoplastic yarns are also present, result in a transference of plasticizer from the non-thermoplastic yarns to the thermoplastic yarns, thus removing greasiness. The heat treatment may be effected at 250-300‹F. e.g. by passing the fabric through a heated chamber or over a heated surface. The thermoplastic yarns may be of cellulose acetate or other cellulose ester or ether or of a synthetic linear polyamide such as poly-hexamethylene adipamide. The non-thermoplastic yarns may be of cellulose. The fabric may be made by weaving, knitting, knotting, or netting. The plasticizer may be incorporated by dipping, coating, or spraying, a solution of the plasticizer in an organic solvent, preferably containing a penetrating agent. Dibutyl tartrate, triphenyl phosphate, dimethyl and diethyl phthalates, and alkyl toluene and xylene sulphonamides, are specified plasticizers for cellulose acetate. The penetrating agent may be Turkey red oil, xylene, toluene, Monopol oil (Registered Trade Mark), pine oil, sulphonated pine oil, cyclohexanol, cyclohexanone, diacetone, and tetrahydronaphthalene. Ageing may be effected by leaving the fabric for at least five days in a chamber heated to 85-160‹F. In an example, a fabric containing cellulose acetate and cotton yarns is dipped in a solution of dimethoxyethyl phthalate in ethanol and is then passed through nip rollers to remove excess solution. The fabric is dried by passing it through a heated chamber. It is rolled and placed in a room maintained at 120‹F. for five days. After the ageing, it is unrolled and passed round a cylinder heated to 265‹F., the time of contact being about 10-20 seconds.
