Title: Speckle-free hologram recording apparatus
IPC: G03H1/32
Filed: 1968-08-02
Abstract: 1,218,813. Holography. R C A CORPORATION. Aug.2, 1968 [Aug. 23, 1967], No.36939/68. Heading G2J. Apparatus, for recording a hologram by simultaneously exposing a given area of a hologram recording medium to an information carrying beam and a reference beam of coherent radiation to produce an interference pattern from which an image can be reconstructed with a predeterminable ultimate resolution limit, comprises means for producing a given amount of redundant information about an object in orderly fashion in the information beam while concomitantly introducing into the recorded hologram interference pattern hologram noise having a maximum spatial wavelength no greater than and preferably less than said resoluion limit. The redundant information is formed by forming the information beam 218 as a multiple beam with a zero order component and two first order components symmetrically angularly displaced from the zero order an angle #. This is preferably achieved using either one-dimensional or two-dimensional pattern phase diffraction grating 214. The beam after passing through grating 214 passes a lens 214 and then a transparency 216, which is focused on a recording medium 220 having a surface area of 1 to 10 sq. m. m. The line spacing of the diffraction pattern is such that the maximum point of the first order components coincides with respective opposite ends of the recording medium 220, and that the noise interference pattern generated has a maximum spacing no greater than the resolution limit of the hologram. The phase diffraction grating may have a substantially sinusoidal variation function, a generally triangular or a generally trapezoidal variation. If desired the phase diffraction grating may be replaced by beam splitters or optical tunnels.

Title: Improvements in apparatus for reading human language
IPC: G06K9/64
Filed: 1959-11-03
Abstract: 885,930. Automatic character reading. GENERAL ELECTRIC CO. Nov. 3, 1959 [Nov. 4, 1958]. No. 37246/59. Addition to 796,579. Class 106 (1). In the parent Specification, characters are sensed to derive a waveform signal which is passed through a tapped delay line, resistive correlation circuits for each character being connected to the tappings and arranged so that each gives a higher signal than the rest at the instant its corresponding waveform is properly positioned in the delay line. The circuit having the highest output signal is determined by comparison with the signals on all other lines. In the present invention this determination is facilitated by so arranging the resistors of the correlation circuits that the output for all waveforms except the one to be recognized is substantially zero. A simplified system is shown in Fig. 1 having a delay 10 with only three tappings and the same number of circuits 14, 15 and 16, each capable of recognizing a different character. The waveforms of the three different characters are shown in Fig. 2 and the values at the tappings are indicated on vertical lines A, B and C. If circuit 14 is designed to recognize waveform WS-1 it is adapted to give an output for this waveform only and to produce a zero signal for the other two. The signal produced by the summing resistors of circuit 14, 34, 35, 36 is to have a value greater than zero, say 1 volt for waveform WS-1 and zero for the other two. The signals at the tappings may be represented as A1, B1, C1 for the first waveform; A2, B2, C2 for the second and so on. If the ratios of the potential dividers are x, y, z, then the summed outputs are represented as follows: From these three equations, knowing the expected signal values the values of x, y and z can be determined. This is repeated for each circuit 15, 16, negative resistances such as the feed-back amplifier 47 being used where necessary. The terminals 40 are applied to comparators as in the parent Specification.

Title: Improvements in or relating to the manufacture of moulding mixtures and articles moulded therefrom
IPC: C08G8/00
Filed: 1930-12-19
Abstract: Relates to moulding mixtures of the kind comprising a filler and a potentially reactive artificial resin of the phenol-aldehyde, urea-aldehyde or polyhydric alcohol-polybasic acid type.  According to the invention the binder is produced by the conversion of the resin in the A stage dissolved in a B-resin solvent into the B state while so dissolved.  The solution may be mixed with the filler either before or after the conversion of the resin into the B state.  The A resin may be dissolved as such or the resin forming components may be dissolved in a B-resin solvent, the solution then being heated, either before or after being mixed with the filler, to form the A resin.  The solvent may be wholly or partly removed from the mixture before the final hardening.  Suitable solvents are (a) for phenol-aldehyde resins, furfural, hydrogenated phenols such as cyclohexanol, methyl hexanol (or commercial mixtures thereof with cyclohexanone and methylcyclohexanone known respectively as hexalin and methylhexalin) and hexahydro-b -naphthol, (b) for urea-aldehyde resins, dichlorhydrine and (c) for polyhydric alcohol polybasic acid resins, oxalic acid ethylesters, phthalic acid dibutyl or diethyl esters and corresponding lactic acid esters.  In examples (1) 80 kg. of phenol aldehyde resin in the A stage are dissolved in 20 kg. of cyclohexanol and heated for from 15-60 minutes to 110 DEG  C.: the solution is then mixed with 100 kg. of wood dust and the mixture is moulded under heat and pressure; (2) 75 kg. of the initial condensation product from phthalic acid and glycerine are dissolved in 25 kg. of ethylester of oxalic acid and the solution is heated until the separation of water is terminated; the solution is then mixed with 25 kg. of asbestos and the mixture is moulded under heat and pressure.  Other examples are given. Specifications 295,335, [Class 22, Cements &c.], 347,611, and 368,807, [both in Group III], are referred to.

Abstract: 852,086. Two-way writing telegraph. MERO, P. G. S., [trading as ELECTROWRITER CO.]. Nov. 28, 1958, No. 38449/58. Class 40 (1). In a two-way writing telegraph the same styli transmit and receive, the position of the receiving stylus being made to correspond to that of the transmitting stylus by a motor-driven self-balancing potentiometer system. As shown in Fig. 1, the " Y " co-ordinate of stylus 37 at station 10 determines the output of secondary 27 of transformer 16, this output is added to that from winding 31 and transmitted by lines 18 to the receiving station. At station 11 the transmitted signal is rectified and compared with a similarlygenerated local signal and the error signal fed to amplifier 84 to drive motor 61 and stylus 70 which moves to reduce that error voltage. The " X " co-ordinate transmission is by means similar to those described earlier. The pressure exerted on pad 12 by the operator at station 10 closes the circuit of coil 181 bringing stylus 70 down on to the pad at station 11. Transmissions may be made from station 11 to station 10 after changing over the signal line switches. The primaries of all the transformers are fed from a common source thereby, it is stated, compensating for attenuation of signals on the lines. By adapting the circuits shown in Figs. 2 and 3 the number of lines linking the stations may be reduced to four.
