Title: Dry process for the finishing or organic material continuous dry transfer-printing process on textile webs made from organic material and appar
IPC: C08J7/00
Filed: 1972-12-21
Abstract: 1425579 Transfer coating process CIBAGEIGY AG 21 Dec 1972 [7 April 1972] 59182/ 72 Heading B2E [Also in Divisions B5 and D1] A "dry" process for finishing an organic material comprises contacting the organic material with an inert carrier, the surface of which has been treated with at least one "textile finishing agent" capable of transferring in the vapour state at atmospheric pressure at at least 80C to the organic material, heating to at least 80C to transfer the finishing agent, and separating the carrier from the material. The carrier may be aluminium, steel, plastics, paper, paper coated with vinyl resin, ethyl cellulose, polyurethane or PTFE. "Textile finishing agent" is the active chemical in any chemical operation to which fabrics may be subjected to make them marketable, but does not cover dyestuffs and optical brighteners. However, dyes and brighteners can be applied together with the finishing agents. The term "dry" means that no liquid is present during the step of transferring the finishing agent from the inert carrier to the organic material. The finishing agent may be or comprise C 17 H 35 NCO, C 8 H 17 CH 2 CH.CH 3 .OCOCHCH 2 , or CH 2 C.CH 3 .COO(CH 2 CH 2 O) 7 CH 3 . These compounds may have bateriostatic, fungistatic, fungicidal, antistatic, oil and water repelling, handle-improving-or fire proofing-effects. Mixtures of finishing agents can be applied simultaneously. Different finishing agents can be applied to opposite surfaces of one fabric. The finishing agent and a bonding agent may be applied to the inert carrier in water or specified organic solvent solution by spraying, coating or printing Only a part of the carrier may be treated. The bonding agent may be alginate, tragacanth, polyvinyl alcohol, muoin, starch ether, oarubin, dextrin, etherified or esterified mucilage, carboxymethyl cellulose, polyacrylamide, nitre-cellulose, cellulose acetate, methyl-, ethyl-, propyl-, isopropyl-, benzyl-, or hydroxethyl-cellulose. The treated inert carrier and organic material may be brought into contact in an oven, on a hot drum or hot plate, optionally under pressure and vacuum These devices may be heated by steam, oil, infra-red or microwave radiation. The organic material being treated can be cotton, wool, silk, cellulose esters, nylon 66, poly-#-caproolactam, poly-#-aminoundecanoic acid, polyurethane, polyethylene glycol terephthalate, polyacrylonitrile, polypropylene, viscose, mixtures thereof, leather, leather substitute, paper, cardboard or wood. The organic material may be in the form of fibres, films, sheets, slubbing, woven, non-woven, knitted or looped fabrics, needled felts or yarns. Specification 1425580 is referred to.
Patent GB-594984-A (GB)
Abstract: 594,984. Scaffold clamps. SALOPIAN ENGINEERS, LTD., and BURN, R. M. G. April 5, 1945, No. 8377. [Class 20(ii)] A clamp assembly, m o r e especially for scaffolding and like tubular structures, for connecting at right angles the ends of tubes or rods up to six in number, comprises members of three kinds viz. a separate socket member A, a separate bracing bar B, and a bracing bar and sockets (or socket) integral with one another, C. The members A have clevices a, with bolt holes, to receive the ends of the members B, and a pair of lugs a<1> at the two sides of a longitudinal split a2, the lugs also having holes to receive clamping bolts. When two members A are joined by a member B the end edges b2, b<3> of the latter engage against the shoulders a<5> and relieve the bolts of shear stress. An example is shown of a clamp assembly for four tube ends, utilising two members of the kind C and three separate bracing bars B. Four members A and five members B could be used for the same purpose, and it is possible in clamp assemblies for any number of tube ends from two to six to be constructed of members of kinds A and B only. Tubes of different diameters may be joined by using appropriate sockets. The Specification also states that it is possible to form a clamping member consisting of a number of sockets with integral bracing bars as a single diecasting.

Title: Colour television camera

Abstract: 1357190 Colour television camera SONY CORP 22 Dec 1971 [26 Dec 1970] 59681/71 Heading H4F [Also in Division H1] A multi-diode target for a colour image pickup tube comprises a pair of comb shaped electrodes 25A, 25B (Fig. 3) each connected to the diodes of alternate rows, and a pair of index electrodes running generally parallel to the columns of diodes and connected to respective bus-bars 32A, 32B, colour filter elements 37 being provided in front of each diode. Referring to Fig. 4 an N-type silica substrate 20 is provided with P-type regions 22 each having an N- type region 23 on its front surface to form a diode. This surface is covered with a transparent insulating layer 24 except over the regions 23, and the conductors 25 (not shown in Fig. 4) extend across the insulating layer; this side of the target is completed by the filter layer 36 containing the colour filter elements 37, and the glass face-plate 35. The other side of the substrate is covered with an insulating layer 28, except over the regions 22, on which the index electrodes 29 are provided. Each index electrode comprises square portions surrounding areas 22 in alternate rows, joined by neck portions which pass between the diodes of the intervening rows (Fig. 5, not shown). In operation anti-phase square waves at line frequency are applied to electrodes 25A, 25B so that whilst one line is being scanned adjacent lines of diodes are inoperative and there is no undesired signal from them. Anti-phase square waves at field frequency are applied to the index electrodes so that the index signal reverses in phase at field frequency in order to cancel any hue distortion resulting from index signal phase changes caused by interference between the luminance and index signals; the colour signal reverses in phase at line frequency because of the staggering of the diodes in adjacent rows. Thus the output at terminal 44, Fig. 1, comprises a luminance signal which is separated by a filter 50, a colour signal reversing in phase at line frequency, and an index signal reversing in phase at field frequency. The index and colour signal separated by filter 51 is passed directly and through a one line delay 52 to an adding circuit 53 and to a subtracting circuit 54 which recover the index and colour signals respectively. The index signal is passed directly and through a phase inverter 56 to a switch 55 operated at field frequency, thereby removing the change of the phase at field frequency. The resulting index signal is then subjected to phase reversal at line frequency by means of a phase inverter 58 and a switch 57 operated at line frequency. This signal provides the three reference signals for the synchronous detectors 61 which recover the individual colour difference signals R-Y, G-Y and B-Y which are combined with the luminance signal in the matrix circuit 62.

Title: Determination of the shape of analog waveforms
IPC: G01R19/04
Filed: 1970-12-16
Abstract: 1328834 Determining waveform shape TEXAS INSTRUMENTS Inc 16 Dec 1970 [2 Jan 1970] 59752/70 Heading G4C The form of an electrical signal, e.g. the distorted signal read from a magnetic tape, is determined by comparing the relative signal levels at time spaced locations along the waveform and generating signals indicative of the shape of the wave in response to the results of the comparisons. The signal is passed through a series of delays 22, 24, 26, the relative signal levels at the input and output terminals of each delay being compared by comparators 28, 30, 32. The letters A, B, C, and D represent four spaced locations (in time) on a waveform. If B > A, C < B and D < C then the waveform has a positive peak. In this case the outputs of the comparators will be X, Y, Z. A NAND gate 36 will thus produce an output pulse indicating a positive peak and NAND gate 38 a pulse indicating a peak. In an embodiment, Fig. 7, the signal is passed to a delay line via a noise filter 202. The delay line has a number of taps which are connected to comparators in a fashion analogous to that shown in Fig. 2. In addition the input signal is biased to a level V+E (where V is the input signal and E is constant) and to a level V-E by means of the first two amplifiers 228, 230 and the transistors 224, 226. The shifting of the signal at the first time delay point allows the peak detector to ignore signals below a critical threshold, e.g. due to noise. The NAND gates 256, 258 are analogous to gates 36, 34 in Fig. 2 and provide peak indication signals. The remaining gates and the corresponding outputs provide signals indicative of the slopes of the signal between adjacent peaks. These outputs are generated in response to various sequences of compared signals, e.g. (using the same rotation as above) B > A, C > D and D > C which indicates a continuously rising signal level.

Abstract: 748,923. Ignition systems. NAPIER & SON, Ltd., D. Nov. 12, 1954 [Nov. 19, 1953], No. 32069/53. Class 7(4) [Also in Group XXXVII] In an electric spark generator such as an ignition system there is provided means for ionizing a main spark gap 10 by a H-F H-V discharge of low energy and means for then passing a high-energy discharge at L.V. across the gap 10, the energy for ionizing the gap and for the L.V. discharge being stored in the same main condenser 21. The condenser 21 is continuously charged, except when a pair of contacts 20 are closed by a 350 volts hand-operated D.C. generator 24; the latter drives a cam 25 at a slow speed, which cam has an acute drop to ensure a quick make and break of the contacts 20 (see also Group XXXVII). During each short period when the contacts 20 are closed energy from the condenser 21 flows to earth through the primary 15 of a H.V. transformer 16 and another condenser 22, which is shunted by a leak resistance 23; the consequent energization of . the secondary 17 produces a spark across an auxiliary spark gap 18 which in conjunction with a H.F. autotransformer 12 causes a H.F. low-energy discharge to ionize the main gap 10 whereupon the bulk of the charge on the main condenser 21 passes through the gap 10 to earth. When the contacts 20 are closed the generator 24 is shorted across the gap 10 and upon the contacts re-opening the. condenser 21 is recharged; the condenser 22 prevents the D.C. generator from being shorted through the winding 15. In a modification, the contacts are actuated by an electromagnet in series between the D.C. source, such as a battery or rectified A.C. mains supply, and the main condenser so that when the condenser charging current is high the energization of the electromagnet is sufficient to hold open the contacts which close as the charging current decreases. Specification 608,324 is referred to.
