Title: Data processing apparatus
Inventor: GRAZEBROOK ROBERT FRANCIS NEED
IPC: G06V30/224
Filed: 1964-02-06
Abstract: 1,040,580. Automatic character reading. ENGLISH ELECTRIC-LEO-MARCONI COMPUTERS Ltd. Feb. 3, 1965 [Feb. 6, 1964], No. 5171/64. Heading G4R. A typewriter adapted to type legible characters readable also by machine has sensing means for automatically sensing the characters and produce representative signals. The paper carriage used in the typing operation is also used to move the characters past the sensing head. Alternatively, the sensing head may move, or flexible light guides may be used, the sensing end moving over the characters and the photo-cell end being fixed. In the form described the head comprises two halves 20, 21, Fig. 3 (not shown), each consisting of a transparent body. Light is shone on to the surface of the paper on lines A and B and is reflected on to photo-cells 22, 23. The character is formed of seven vertical bars two of which are wide and five narrow according to a code. Each half of the head is the width of one of the narrow bars or the spaces between. The outputs from the two photo-cells are subtracted so that when the head senses blank paper there is zero output. When one is on a bar and the other on a space a maximum output is obtained. When both are on a wide bar the output is again zero. The waveform obtained from the subtractor is used to set and reset a trigger as it crosses upper and lower threshold levels close to the zero. The output then consists of seven pulses of which two are long corresponding to the wide bars, and the rest are narrow. This signal is used to frequency-modulate a carrierwave which is transmitted to a distant receiver where it is demodulated. At the receiver the signal is applied to a circuit which gives a signal on one lead for a short pulse and a signal on a second lead for a long pulse and these are entered at " 1's " and " 0's " into a shift register under the control of the seven leading edge pulses suitably delayed. The seven parallel outputs are applied to a decoding matrix to identify the character, as a marking on one of a group of leads. These are passed through a control unit to another typewirter, a punch or a magnetic tape recorder. At the end of a line a special symbol causes the control unit to send a signal back via the H.F. link to the control unit at the transmitter to initiate sensing the next line.

Abstract: 938,738. Moulding refractory powders. GENERAL DYNAMICS CORPORATION. Feb. 14, 1961 [Feb. 29, 1960], No. 5493/61. Class 87(2). A method of forming finely divided particles of a refractory material of an electrical conductivity approximating that of graphite, e.g. graphite, conductive ceramics, metal powders, carbides or oxides, into a very dense body comprises compressing the particles in excess of 5000 p.s.i. in a hollow-walled die 16, the die being continuously cooled by circulation of liquid between the hollow wall, and simultaneously heating the confined particles to a temperature above their fusion point by an electrical current, so that the particles are compressed into a uniformly strong dense, non-porous body, the cooling of the die 16 allowing continuous repetition of the method in a single apparatus. The particles are compressed by two plungers 22 of graphite fixed to conducting plates 20 e.g. of copper. Pressure is applied from hydraulic cylinders 24 through non-conducting plates 18. The die 16 is made of poorly conducting material e.g. a suitable carbon. A hollow-walled jacket 10 surrounds the die 16, the cooling liquid being circulated through this jacket. With currents of 3000 amps at 20 volts the temperature reached is 2500‹C. and with a pressure of 5000 lbs./sq. inch the compacted body has a density of up to 2À03 g./cm<SP>3</SP>. in the case of graphite containing 10% pitch. In an alternative embodiment, Figs. 3, 4 (not shown) induction heating is used and a water cooled coil surrounds the die and water jacket and is supplied with a high frequency alternating current, the water jacket and the plungers being fitted with conducting plates e.g. of metal on their ends to concentrate the field in the die. A longitudinally extending partition (not shown) of a thermal insulator e.g. alumina is disposed between the walls of the water jacket in such a position with respect to the fluid inlet and outlet orifices to ensure circulation of the coolant round the die.

Mixtures may be used.  Specified polyalkylene glycols may be prepared from one or more cyclic oxides, e.g. ethylene, propylene or butylene oxides, tetrahydrofuran or oxacyclobutane, using a catalyst, e.g. KOH, in the presence of an initiator having two active hydrogen atoms, e.g. water or diethylene glycol. Polyisocyanates specified for polyurethane formation are: hexamethylene diisocyanate, tolylene-2,4 and 2,6-diisocyanates, diphenylmethane - 4,41 - diisocyanate, 3 - methyldiphenylmethane - 4,41 - diisocyanate, m- and p-phenylene diisocyanates, chlorophenylene - 2,4 - diisocyanate, dicyclohexylmethane diisocyanate, 2,4,6-triisocyanatotoluene, 2,4,41 - triisocyanatodiphenyl ether and isocyanurate trimers and uretdione dimers of tolylene - 2,4 and 2,6 - diisocyanates.  Mixtures of isocyanates may be used.  1-10% water is used.  Other additives may be: catalysts, e.g. tertiary amines, iron and manganese acetylacetonates, dibutyltin dilaurate, and stannous octoate; surface-active agents, e.g. oxyethylated phenols and fatty alcohols, sulphonated methyl oleate, alkyl and aryl polysiloxanes and siloxane-oxy-alkylene copolymers, flame retardants, e.g. tri-b -chloroethyl phosphate and antimony oxide, plasticizers, e.g. tricresyl phosphate and dioctyl phthalate, colouring, fillers, e.g. carbon black, and silica, colour stabilizers, whitening agents and antioxidants, e.g. tert-butyl catechol and sterically hindered phenols.  In Example (1) a polyether prepared by interacting polypropylene glycol and trimellitic acid under nitrogen in the presence of tetraorthobutyl titinate, was treated with water and tolylene-2,4 and 2,6-diisocyanate in the presence of 4-dimethylaminopyridine, dimethylbenzylamine, stannous octoate and a siloxane-oxyalkylene block copolymer.  The reactants were allowed to foam in a mould. In Example (2) the carboxyl derivative used was pyromellitic dianhydride.
