Patent GB-449954-A (GB)
IPC: G03C7/14
Abstract: 449,954. Copying lenticular films. I. G. FARBENINDUSTRIE AKT. - GES., Frankfort-on-Main, Germany. Jan. 7, 1935, No. 531. Convention date, Jan. 9, 1934. [Class 98 (ii)] Lenticular films to be reproduced by projection printing are produced by exposure through a multicolour filter arranged beyond the focal point of the taking objective and, during reproduction, are illuminated through the embossed side so that the trace of the rays passing through the centre of the surface of each lenticular element and through the centre of the image of the colour filter formed behind the element on exposure, intersect on the emulsion side of the film at a point corresponding to the point of intersection during exposure. Preferably, the point of intersection of the rays on the side of the lenticular blank film is chosen so that its distance from the blank film corresponds with the required distance of the projection filter. To avoid the use of an objective of large aperture a filter having the colour sequence repeated entirely or partially on each side of the central sequence may be used. In this case a mask composed of a central rectangle and a rectangle of smaller height on each side may be used, such a mask is shown in Fig. 3. For printing, a light source having illuminated apertures arranged in the form of steps or a source as described in Specification 399,977 is used. Fig. 6 shows one form of printing device. The original film W is illuminated by the light source Lr, Lg, Lb through the condenser J and projected by the objective O on the lenticular blank K. The distance G between O and N is equal to the distance between the original film and the plane conjugate with the plane of the filter during taking. Specifications 356,701, 364,559, 369,262, 395,124, and 399,984 also are referred to.

Abstract: 1,085,290. Knotting. M-ASSEY-FERGUSON-PERKINS Ltd. Oct. 27, 1964 [Nov. 19, 1963], No. 45529/63. Heading D1C. A knotting mechanism for a baling machine comprises a concentric bill hook 12 and cord disc 22 operated by a segment gear from an input shaft 5 which is turned periodically by the plunger of the machine so that during one revolution of the shaft 5 the bill hook is turned through one revolution and the cord disc, being driven from the bill hook shaft 11 by an epicyclic gear, is turned through a fraction of a revolution in a part of the time taken for a revolution of the input shaft. The cord disc, Fig. 1 (not shown) comprises three concentric discs with notches 26 and diametrically opposite notches 27. Initially the free end of the twine passes through the notches 27, over the top disc and through the notches 26 to be gripped therein by a series of spring loaded fingers 28; from there it passes under the bracket 8 and around the bale. The needle 4 lays the other end 7 in the notches 26 so that on revolution of the shaft 5 the bill hook knots together the ends 6 and 7. The part of the twine 6A lying beyond the end 7 is located in the notches 27 in readiness for the next knotting operation. In a modification Fig. 9 (not shown) the cord disc has a two pairs of closely adjacent notches 27A, 27B, 26A, 26B in order that for each knotting operation only one part of the twine is severed and no loose ends are left in the knotting machine.

Abstract: 1,184,148. Injection lasers. INTERNATIONAL BUSINESS MACHINES CORP. 26 Sept., 1968 [26 Oct., 1967], No. 45665/68. Addition to 1,097,023. Heading H1C. In an injection laser in which the contacts are so shaped that as the current applied to them varies there results a change in the portion of the laser which emits coherent light a further contact having a constant length in the direction of lasing is provided, the arrangement being such that the sum of the products of current and length in the lasing direction of individual contacts is in excess of a threshold value for lasing. A PN junction laser, Fig. 1, is provided with three contacts 13, 14, 15 on one side thereof and a common contact on the opposite side. Contact lengths of contacts 13, 14 are co-ordinated with half rectified cosinusoidal and sinusoidal current signals I 1 , I 2  so that scanning of the line along which lasing may take place will occur when the condition of the laser is above a threshold level. The threshold level is controlled by the length of contact 15 and its current signal I 3 . In one arrangement the current signal I 3  is in the form of a pulse code modulated input, the amplitude of the pulses in conjunction with the length of contact 15 and with the lengths of contacts 13, 14 and their respective currents being such as to exceed the threshold condition and produce a scanning light beam. The light beam will only be produced during the duration of the pulses. In an alternative arrangement the lengths of the contacts, and the input currents I 1 , I 2 , I 3  are sufficient to cause the lasing threshold to be exceeded. By amplitude modulating the signal I 3  the intensity of the output beam is correspondingly modulated while it continuously scans. In a second embodiment, Fig. 3, the laser body is in the form of a cylindrical body and is provided with three contacts 39, 40, 41 on its suppermost surface, contacts 39, 40 being shaped to have sinusoidal and cosinusoidal lengths as a function of the angle while contact 41 has a constant length as a function of angle. The laser operates in the same manner as Fig. 1 except that the output beam sweeps radially between 43 and 46.

Abstract: 1,074,956. Printing-surfaces. J. A. BRUN. Oct. 20, 1964 [Nov. 20, 1963], No. 45805/63. Heading B6C. A series of members (9), Figs. 4 and 5, each formed with a character or design (10), only in the area of which light can pass through, and with long and short shoulders (17, 16). In use, a row of members (9) are assembled with the face (12) downwards on a rail (14), Fig. 2, comprising two rail members (23, 24) for supporting the shoulders (17, 16). The rail includes end flanges (25) which can be accommodated in recesses (20) in side members (18, 19), Figs. 1 and 2, of a frame (15). A plurality of rails (14) each with a row of members (9) is assembled in the frame (15) so as to form a column, the shoulder (17) of each member (9) extending partly over the rail member (24) of the adjacent rail, as shown in Fig. 6. The frame also comprises members (21, 22) with recesses to accommodate the outside shoulders of the end lines. The members (9) are held on the rails by small springs. Short lines are completed by metal blanks, and large blanks (27) with shoulders can be used with half-length rails aligned therewith, as shown in Fig. 1. The individual members (9) may be of transparent plastic or glass coated on the face (12) with an opaque material such as plastic, a metal foil or photographic negative, or a thin metallic film sprayed on, the design being formed in the opaque material by cutting, etching, or engraving; or the members (9) may be of opaque metal or plastic with the design cut out thereof.

Abstract: 1,061,986. Cathode-ray storage tubes. WESTINGHOUSE ELECTRIC CORPORATION. Nov. 21, 1963 [Dec. 3, 1962], No. 46027/63. Heading H1D. The target of a fast response storage tube includes a porous insulating layer-e.g. of 1- 5% of the bulk density-having one face exposed to a potential stabilizing reading electron beam, and the other contacting an electron - transmissive conductive film upon which a writing electron beam impinges to produce secondary electrons in the porous material. As operated, a charge pattern corresponding to the written information is produced on the exposed surface by a combination of secondary emission from that surface, and of " secondary electron conduction," i.e. the movement of secondary electrons through the porous layer by way of the voids rather than by solid state conduction in the insulating material. The electron image produced by a caesium/antimony photocathode 14 (Fig. 1, not shown) is focused upon the aluminium film (34) which is supported in a nickel, iron, or cobalt ring (32) and itself supports a porous layer (36) of potassium chloride, magnesium chloride, or magnesium oxide. A nickel grid (40) collects the secondary electrons emitted from the surface of layer (36), which is scanned by a low-velocity electron beam from gun (20) to stabilize it at gun cathode potential, whereby a positive bias voltage applied to layer (34) maintains a low field across the porous layer such that the remaining secondary electrons produced in layer (36) are collected by layer (34). A further grid (Fig. 3, not shown) may be introduced between collector grid (40) and layer (36), to prevent the surface of the latter from attaining a potential with respect to the gun cathode greater than the first cross-over point of the layer material, with consequent breakdown and destruction of the latter in the resulting high field. The porous layer may be produced by evaporation of potassium chloride in argon at reduced pressure. Modifications referred to include the substitution of a scanning electron beam for the photo-cathode (14), to provide a scan converter tube, and the disposition of both read and write electron guns on the same side of the storage target. Reference has been directed by the Comptroller to Specifccation 911,560.

Title: An improved process and device for the hot fixing of webs of synthetic textile
Inventor: BRUCKNER KARL
IPC: D06C7/02
Filed: 1965-11-02
Abstract: In a process for hot-fixing webs of synthetic textile material by means circulating air containing water vapour, the circulating air is indirectly heated by heating gases and water vapour produced by heat transfer from the heating gases is injected into the air.  Heat transfer from the heating gases to water for producing the water vapour may take place in the zone of maximum heating gas temperature. The water may also be pre-heated in the zone of minimum heating gas temperature.  In one embodiment (not shown) a flat web (2) passes between nozzles (4a, 4b) to which air is supplied by fan (3) which circulates the air through heat exchanger (7) in the direction of (5, 6).  In heat-exchanger (7), the air is heated by passage over a tube provided at one end with burner (8), as a source of heating gases, and at its other end, with gas exhaust flue (9).  Water, preheated in coil (13) adjacent flue (9), is vapourised in coil (10) adjacent burner (8), and is injected into the circulating air by injection device 12 disposed between the heat-exchanger (7) and fan (3).  The water vapour introduced into chamber (1) causes a slight excess pressure within it, thus preventing outside air from entering, and ensuring that the web is fixed in an atmosphere containing water vapour and poor in oxygen.

Abstract: 1,145,436. Laser-recording on thermoplastic records. NATIONAL CASH REGISTER CO. 24 Oct., 1967, No. 48281/67. Heading G5R. [Also in Divisions G2 and H4] Information is recorded by causing an amplitude-modulated laser beam 2 to scan a thermoplastic record 18. As shown, a linearly polarized laser beam 2 is focused on a mirrored polygon 13 rotated about axis C and oscillated about axis D, the reflected beam being focused by lenses 14, 17 to scan the record 18. Electrical information is fed to a polarization rotator 6, e.g. a Pockels cell, while a modulation converter 4, e.g. an analyser, converts the rotational polarization into amplitude modulation. A document 30 may be recorded by splitting the laser beam at 3 and focusing a portion 2b (e.g. 10%) to scan the document 30. The reflected light is sensed by a photodetector 38 whose output supplies the rotator 6. Vertical and horizontal synchronizing pulses V 1 , V 2  and H 1 , H 2  are obtained by photo-cells 36, 37 adjacent lens 14 and photo-cells 34, 35 illuminated by a separate source 32 reflected from the polygon 13. Readout is effected by illuminating the record 18 by Schlieren optics 19-22 and projecting the image on to a screen 23, the record being shifted by adjusters 40. Record details.-A suitable thermoplastic comprises 75% nitrocellulose binder and 25% dye, e.g. nigrosine dye having a high absorption at the laser wavelength. The thermoplastic material is deposited on to a glass substrate and when solvents have been evaporated, the film is 2 microns thick. Successive scans produce grooves 1-3 &c. (Fig. 4) due to localized heating. The scan line spacing may be 4 microns and the complete record 18 contains a matrix of discrete records, each 3 mm. square (Fig. 2, not shown). Erasing is accomplished by scanning the record with a reduced line spacing, e.g. 1 micron. Circuitry (Fig. 6, not shown).-The sync. pulses produced by the photo-cells 34-37 operate AND gates and flip-flops (62), (72) to control passage of the information signal (e) from photo-cell 38 to the rotator 6. The polygon 13 is arranged to produce a 1 micron scan line spacing, i.e. that for erasing, so that during recording the circuit operates via a 4-counter (64) to allow every fourth scan to be recorded to give the 4 micron spacing required for recording. Erasure may be conducted over the entire record or selected portions by suitable choice of the waveform of the erase signal (70) fed via a gate (75) to the rotator 6.

A postage stamp on an envelope is checked as regards colour and dimension by a pair of optical systems directed at points spaced by the longitudinal dimension of the coloured area, the systems each including a light source, two or more different colour filters with a corresponding number of detectors the outputs of which are analyzed to give a stamp colour indication. In an arrangement using red, green and blue filters, the pulses from corresponding colour detectors in the two systems as the points pass from stamp edge to colour and from colour to stamp edge are applied to level comparison circuitry and the outputs are differentiated to provide pulses from monostable multi-vibrators which are coincident in the case of a correctly dimensioned stamp, and which are passed via respective "and"and "or not' gates to a circuit which gives a coded colour indication output in accordance with the input from all the detectors, and showing the presence or absence of red, blue and green respectively on six output terminals. The logic circuits may include insertable delay circuits whereby compensation may be introduced for stamps affixed with their other dimension across the points. In a modified colour analyzing arrangement pulses are developed when the compared outputs from pairs of detectors exceed certain limits. Tables of outputs for various coloured stamps are included. The stamps may be illuminated at each inspection point by one or two lamps and the reflected light is passed through apertured diaphragms and a number of half-silvered mirrors to the filters and respective detectors. Polarization filters may be included to eliminate specular reflection, one in the illumination path and one in the path of the reflected light, or multi-layered thin films forming an interference polarizing mirror may be provided in common to both paths. Control of the investigation apparatus by a photo-cell or photo-cells which respond(s) to the edges of the envelope and permit(s) scanning of a limited envelope area is also described. The machine may sort different classes of mail.
