Title: Pattern identification apparatus
IPC: G06V10/24
Filed: 1965-05-10
Abstract: 1,074,858. Pattern recognition. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 10, 1965 [June 18, 1964], No. 19556/65. Heading G4R. A sample contour pattern such as a finger print is compared with a stored reference pattern to obtain an identification by scanning the sample pattern to produce a train of electrical pulses, the scanning means being controlled first to search for a known crosssection through the sample pattern by going through a predetermined sequence of scans, and, when it is found, then to make a series of radial scans covering the pattern, the trains of pulses produced being compared with trains of pulses corresponding to the reference pattern. The preliminary search for the reference position is effected by a group of 21 radial scans, Fig. 3 (not shown), spread over 20 degrees of arc. The signals from each scan are compared with stored reference signals representing the scan A. If no match is found in the first group of scans the centre is stepped to a new position and the scans repeated. The centres successively tried are arranged in a rectilinear spiral, Fig 4. (not shown). If all centres are tried without finding a match the finger is indicated as unknown. If the line A is matched by a crosssection in the reference store searching stops and the centre and angular position of the scan in which it is found become the fixed references for the identification phase which follows. For identification, a series of radial scans are made, separated by 10 degrees, Fig. 5 (not shown), and, if necessary, covering the full 360 degrees. Each scan is compared with the corresponding scan in the reference store. If the predetermined probability is reached before all the scans are made, the scanning is stopped. The finger may be placed roughly in the correct position by a fixed top stop and movable side plates which are spring loaded to grip the finger. The scanner may consist of a C.R.T. or a matrix of photo-cells. The reference store may comprise a magnetic tape, discs, drums or cards, a photographic record or an electrostatic store. The comparator comprises an And gate and a counter which counts the number of pairs of pulses which coincide in the pulse trains from the scanner and the reference store. The output of the counter is compared with the number set into a probability level setter and a decision made according to whether or not this number is exceeded. The apparatus may be used as an identity check, the individual, having stated his name, has his fingerprints compared with reference patterns associated with that name.

Patent GB-381956-A (GB)
Title: Process for coating metals to be submitted to cold deformations
IPC: C23C26/00
Filed: 1931-07-08
Abstract: To facilitate mechanical working in the cold, e.g. cold rolling or cold drawing, a metal object, e.g. of iron or steel, is coated with a thin and easily removable layer of lead by immersing the object in a solution of a mercury salt at about room temperature, i.e. not above about 20 DEG  C., and for not longer than one minute, so that no effective amalgamation occurs, and then applying the lead in a powdered, dispersed, or dissolved state in the cold or with only slight heating.  The lead may be applied by rubbing or projecting powdered lead on the mercury-coated object, by immersing the object in a colloidal suspension or solution of lead, by precipitating lead on to the object by the addition of a metal such as zinc to a lead salt, or by immersion in an acidified solution of an organic salt of lead, e.g. lead acetate acidified with acetic acid at a temperature of from 25-37 DEG  C.  The mercury salt used may be bichloride of mercury.  After the mechanical working the coating is removed by warming gently which volatilizes the mercury and breaks the lead coating which is then removed by pickling.

Abstract: 1,057,214. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. May 11, 1965, No. 19806/65. Heading H1K. Semi-conductor devices are made in which at a PN junction between a layer of one conductivity type and a layer of the opposite conductivity type which is of relatively high resistivity the surface of the latter layer and the emergent PN junction include an acute angle. Although applicable to diodes and transistors the invention is mainly described with respect to a silicon controlled-rectifier. (Germanium is also a suitable semi-conductor for such devices). The thyristor shown has a main body in the form of a circular disc of 20-40 ohm cm. N-type silicon. The gate region 6 and main part 3 of the anode region are formed by gallium diffusion and the enhanced conductivity part 2 of the anode region is formed by boron diffusion. Phosphorus diffusion is used to form the annular cathode region 8. Genetic silicon oxide masking is used during these diffusion stages. The three electrodes are applied by electroless nickel plating followed by plating with gold. An abrasion treatment, for example using alumina particles in a stream of compressed air, is now used to shape the surface of the high resistivity region 4 at the junctions 9 and 10, the device being rotated rapidly during the process. The abrasion nozzle may be formed as a rectangular slot having a main dimension lying in a plane parallel to the major faces of the device. The angles α and # produced are preferably about 30 degrees but they need not be made equal.

Abstract: 907,618. Valves. BECHEREAU, L. June 10, 1959 [June 14, 1958; Feb. 19, 1959; May 27, 1959], No. 19846/59. Class 135. [Also in Group XXXII] A double-acting valve for use in an hydraulic shock-absorber comprises annular oppositely facing valve seats in different planes against which opposite faces of a deformable annular diaphragm comprising a tubular resilient element, an internal cylindrical sleeve forming one piece therewith and a metal part at its outer periphery normally bear and wherein on the flow of liquid in either direction the diaphragm is axially deformed with its lateral cylindrical surfaces remaining parallel to one another. As shown in Fig. 1, a deformable diaphragm comprises an annular rubber member 20 of gradually increasing thickness from its outside to its inside bonded to metal rings 24, 25 and a sleeve 21. The diaphragm normally engages an annular seat 11 on a piston 1 and the inner margin of a ring 7. When liquid flow is in direction f2, the liquid passes through an annular gap between the sleeve and the piston hub. As shown in Fig. 2, the deformable diaphragm comprises a resilient member 41 bonded to internal and external sleeves 41a, 41b. The whole is secured by a circlip 43a to a member 42 having a radially and outwardly projecting flange 42 formed with a seat 43. The pressure of the liquid acting in either direction on the diaphragm is in part balanced by pressure acting on the flange. As shown in Fig. 3, a thick rubber diaphragm 41 is bonded to a sleeve 41a and a member 41b having an inwardly tapered extension 43. The piston 1 which is made in two parts 2a, 2b is formed with orifices 49 and orifices 47 controlled by an auxiliary diaphragm 45. During the pre-lifting period, elastic overpressure tending to build up in chamber 4 is prevented by flow through the orifices 49 and an annular throttling gap 31d to establish a differential pressure on the two sides of the piston 1. Extreme overpressure in the chamber 4 is relieved by the diaphragm 45.
