Filed: 1976-05-06
Abstract: 1536604 Transverse web registering POLYGRAPH LEIPZIG KOMBINAT FUR POLYGBAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB 6 May 1976 [12 May 1975] 18595/76 Heading B8R [Also in Division G3] A transverse web registering apparatus for correcting longitudinal edge misalignment selectively at two different speeds comprises sensing means 7, 8 producing signals corresponding to the transverse misalignment and acting on setting means 5, 6, to displace the web 2 transversely at a speed corresponding to a signal derived via a regulator 9. The two signals are associated with two different transverse displacement ranges. The means 7, 8 may be photo-electric cells spaced at two different distances and effective to produce two signals which when applied to the regulator 9 produce fast or low speed displacement of the web roll 1, respectively, by the piston cylinder assembly 5, 6. In a modification the means 7, 8 may be replaced by a single photoelectric cell associated with four Schmitt trigger circuits. In a further modification the means is replaced by a pneumatic sensing member (18, Fig. 3) associated with a fluid control circuit which causes a pair of pivotal rollers (16) to be displaced angularly at a selected speed.

Title: Electron beam deflection circuit
IPC: H04N3/20
Filed: 1969-04-11
Abstract: 1,260,375. Cathode-ray tube deflection circuits. R.C.A. CORPORATION. 11 April, 1969 [15 April, 1968], No. 18631/69. Heading H3T. [Also in Division H2] In a deflection circuit for a cathode-ray tube, a first bi-directional switching means 24 is arranged to be conductive during the forward stroke so as to connect deflection coil 22 across an energy supply device 23 and a second switching means 46 arranged to become conductive towards the end of the forward stroke, the switching means 24, 36 being coupled via a T- network comprising capacitors 29, 30 and inductor 28. As described, diode 26 is arranged to be conductive at the beginning of each trace so that a deflection current is driven by the large capacitor 23 through the deflection coils 22. Soon after the beginning of each forward stroke, a pulse is induced in winding 31 and fed to the gate of thyristor 25 so that the anode/cathode path becomes conductive when the deflection current passes through zero midway through each forward stroke 8 Ás before the end of each forward stroke, thyristor 37 is turned on by a pulse from the horizontal oscillator 19 so that energy which has been stored into capacitors 29 and 30 is circulated resonantly via circuits including components 24, 29, 28, 36 and 36, 28, 30. This provides a reverse current in thyristor 25 so that after the stored carriers have been dissipated, thyristor 25 becomes turned off, terminating the forward stroke. The resonant current now continues via diode 26 until a further reversal occurs when that diode is also turned off. Energy is thus returned to capacitor 23. Further current reversal similarly turns off thyristor 37 and (later) diode 38 so that a further forward stroke can start. The flyback pulses induced in transformer 43 (tuned to approximately the third harmonic of the flyback frequency) are rectified at 44 to provide E.H.T. for the cathode-ray tube. Circuits 46 ... 50 protect the circuit against E.H.T. flash-over. Capacitor 30 is arranged to resonate with its associated inductance at twice the flyback frequency. Stabilizing image width.-The exchange of energy between transformer 43 and the rest of the circuit is arranged so that, following variation in cathode-ray tube current, the corresponding change in deflection current is approximately one half the change in E.H.T. voltage so that the image width remains constant.

Title: Improvements in or relating to the manufacture of filaments, foils and similar articles from polymerised vinyl compounds
Filed: 1945-07-25
Abstract: Filaments, threads, slivers, fibres, bristles, films, foils and other like products made by extrusion are manufactured by extruding concentrated solutions of copolymers of vinyl chloride and vinyl acetate in moist acetone containing not more than 5 per cent of water and applying to the threads and like products a stretching of at least 300 per cent at a temperature at which they are plastic and in the absence of swelling agents.  The concentration of the spinning solution may be more than 30 per cent and the temperature of the spinning chamber 85-160 DEG  C.  The threads are stretched at 85-100 DEG  C. by passage through hot water, oil or other heating medium. The stretching may be carried out immediately the material leaves the spinning chamber or at any later stage in the processing.  Both the stretched and unstretched material can be finished in any of the usual ways.  The stretched product can be fixed under tension or allowed to retract to any desired extent.  In an example, 46 parts by weight of a copolymer of vinyl chloride and vinyl acetate of approximate molecular weight 25,000 (determined by viscosity measurements) is kneaded for several hours at ordinary temperatures with 56 parts by weight of acetone containing 2 per cent of water. The solution is filtered and spun at 75 DEG  C. into a steam-jacketed spinning chamber at 130 DEG  C.  Cold air enters the chamber near the spinning jet and is drawn off near the base of the chamber.  The thread after passing through a finishing apparatus is wound and doubled by applying a torsion of 200 left-hand turns, passed through water at 90 DEG  C. and stretched 450 per cent.  Specifications 323,846, [Class 2 (ii)], and 451,675 are referred to.

Title: Improvements in or relating to skis
IPC: A63C5/12
Filed: 1947-07-18
Abstract: 662,635. Skis. GOMME, E. D. July 19, 1948 [July 18, 1947], No. 19335/47. Class 132 (i). A laminated ski has an integral or composite layer at the top and an integral or composite. layer at the bottom, these two layers being spaced apart sufficiently to provide a conventional longitudinal flexibility and a high ratio of longitudinal flexibility to torsional rigidity, and being so fashioned as to have a shear modulus of at least 0.4x10<SP>6</SP> pounds per square inch per radian. When the ski is placed in an unloaded condition on a flat surface, it rests on two locations spaced apart along its length and is concavely curved on its under surface. A measure of its longitudinal flexibility is obtained by freely supporting the ski at these two locations, applying a load of 106 lbs. at the point of attachment of the toe iron and measuring the deflection at this point; a conventional longitudinal flexibility is represented by a deflection of 2¥-6¢ inches. A measure of the torsional rigidity of the ski is obtained by clamping a 10 inch lever arm to that one of the abovementioned locations situated at the toe end of the ski, clamping the ski at a distance of 8 inches from the lever arm to a support, applying a weight of 10 lbs. to the end of the lever arm and measuring the deflection in inches of the end of the lever arm. A high ratio of longitudinal flexibility to torsional rigidity is represented by a value of not less than 3À75 when longitudinal flexibility and torsional rigidity are measured by the above-mentioned methods. The outer layers of high shear modulus may comprise ply wood in which the grain in any one ply is arranged at an angle to the longitudinal axis of the ski and to the grain of an adjacent ply. Alternatively they may be of metal, for example the metal known under the Registered Trade Mark " Duralumin," or of plastic sheet, a suitable plastic sheet comprising fabric or paper impregnated with or embedded in phenol-formaldehyde resin. The top and bottom layers may be of different materials while the intervening layers may be of ordinary plywood. The top layer may be shaped so as to provide ribs extending transversely to the longitudinal axis of the ski, preferably in an inclined manner. Thus, as shown in Fig. 2, the top layer may be cut away to provide apertures 24 and crossbars 25. As shown in cross-section in Fig. 4, the top layer 21 may have a hollow rib 22 pressed in it in a similar manner to that described in Specification 631,879. The bottom layer 20 may be provided with a longitudinal groove 26, also as shown in Fig. 4.
