[Also in Division F2] A composite material comprises at least two layers of molecular orientated high density polyethylene fused together with a binding layer of low density polyethylene between successive layers of high density polyethylene. The high density polyethylene can be stretched at 116-126‹ C. with a pronounced effect of molecular orientation and has a crystallite melting temperature of 127-131‹ C., and the melting temperature of the low density polyethylene is 110-115‹ C. The layers of high density polyethylene and low density polyethylene may be fused together with the application of pressure at the fusing temperature of the low density polyethylene with the aid of rollers, the layers of high density polyethylene preferably being kept under mechanical tension in the direction of their molecular orientation while fusion is effected. The layers of high density polyethylene may have differing molecular orientations cross-wise to each other. The composite material may be in the form of a foil, plate, hose or tube.

Abstract: 816,727. Band-pass filters. STANDARD TELEPHONES & CABLES Ltd. Oct. 4,1957 [Oct. 5, 1956], No. 31160/57. Class 40 (8). A band-pass filter for operation within a range of 50 to 500 Mc/s. comprises a number of resonant pi-sections formed by strip transmission lines and capacitors, the sections being capacity-coupled in tandem. The line sections comprise narrow conductors 2, 3 spaced by a solid dielectric sheet 20, e.g. of glass, from a broad conductive plate 21. Each capacitive connection between the sections takes the form of a condenser 7 having several pairs 7a, 7b of fixed plates mounted on posts which are supported by the dielectric sheet 20 and electrically connected to the adjacent ends of the lines. The rotor plates 7c are insulated from ground so that the line to ground capacitance remains constant as the coupling capacity is varied. Tuning capacitors, e.g. 13, 14, are of similar construction, the stator plates 13a, 14a being mounted on earthed posts and the rotors 13b, 14b connected to the adjacent ends of the line sections.

Title: Improvements in or relating to bistable trigger circuit arrangements employing transistors
IPC: H03K3/352
Filed: 1957-10-04
Abstract: 877,412. Transistor two stable state circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 4, 1957 [Oct. 9, 1956], No. 31166/57. Class 40(6) In a circuit employing transistors 1, 2 of the current-amplifying type, in which the bases are connected through resistors 3, 4 to a point of constant potential, the emitters are connected through separate resistors 5, 6 and a common resistor 7 to a second point of constant potential, the emitters being inter-connected by a capacitor 12. Assuming transistor 1 to be conducting, the flow of current through resistor 5 is such that the potentials of the emitter and base are lowered below that of the supply 9 and the potential drop across the common resistor 7 together with that of the supply 9 is such as to hold the transistor 2 biased off at its emitter. A positive input pulse applied over isolating diode 11 is effective to raise the potentials of both emitters so that transistor 2 is rendered conducting. At the termination of the input pulse, the charge existing on capacitor 12 is such that the emitter of transistor 1 is negative with respect to emitter of transistor 2 so that the transistor 2 remains conducting while transistor 1 is cut off. The transistors may be of the point contact type or may be PNPN type. Where the potential drop across resistor 7 is sufficient to bias off the non- conducting transistor, the supply 9 may be omitted. Specification 730,892 is referred to.

Title: Improvements relating to deflection coils
Inventor: SAMPEYS ALFRED MARCOS
IPC: H01J29/76
Filed: 1968-06-28
Abstract: 1,270,943. Electron beam magnetic deflecting systems. EMI Ltd. 20 June, 1969 [28 June, 1968], No. 31168/68. Heading H1D. A deflection coil for a cathode-ray tube is formed by a film of insulating material bearing a pattern of printed conductors, the film being folded and wound to follow the surface of a cone, and the exposed surface of the pattern of conductors being covered by an insulating layer. In the simplest case, a conductive path 2, Fig. 1, is formed around the periphery of the insulating film 1, which is folded along lines 3, 4, 5, and 6 to give the structure of Fig. 2, which is then coiled up, Fig. 3, to give a conical insulating surface with, at diametrically opposed positions on its surface, the coils 7 and 9 superposed and the coils 8 and 10 superposed in such a manner that, in each pair, the magnetic fields reinforce one another. In more elaborate arrangements, instead of a single current path 2, a spiral path, e.g. of 50 turns, may be formed on the film (Fig. 8, not shown), which is of sufficient length, and folded a sufficient number of times, to provide 10 overlying layers, for example, whereby each deflection coil consists of 500 turns. Uniformity of the deflection field may be improved by modifying the shape of the conductive spiral (Figs. 9, 10, 11 and 12, not shown); a cone of any desired angle may be produced by suitably choosing the angle of the folds with respect to the median line of the strip; cones of elliptical or rectangular rather than circular cross-section may be produced; and the spacing between the folds may increase from one end of the strip to the other to allow for the increasing radius of curvature produced by the coiling process. A combined line and field deflection coil system may be produced by forming on the same insulating film suitable conductive patterns together with conductive areas between them to serve as electrostatic shields (Fig. 26, not shown). The insulating film may be of flexible polyester resin 0À001 to 0À002 inch thick, and the conductive patterns may be produced by a printed circuit technique, by etching, or by sticking conductive strip to the film.

Abstract: 484,719. Optical sound - recording. LEER, J. O. VAN. Nov. 14, 1936, No. 31184. Convention date, Nov. 14, 1935. [Class 40 (ii)] When photographically recording sound by displacing a spectrum of the recording light beam relatively to a slit whereby a film whose sensitivity varies according to the wave length of the light, is variably blackened in correspondence with the recorded sounds. the contrast in blackening is increased by using a spectrum, the intensity of different portions of which varies very rapidly with the wave length over the wave length range used for recording. The light source may be a mercury-vapour or other lamp, filters such as Wratten filiters being used when necessary so that the light is intense only over a limited range of wave lengths. The film emulsion is preferably chosen so that the wave length range used for recording is that for which the emulsion is most sensitive. The invention is not limited to the use of a visible spectrum, the references to light including any electromagnetic waves, e.g. those in the ultra-violet region, having similar properties.
