IPC: H03G5/10
Filed: 1964-07-09
Abstract: 1,105,610. Compensating amplitude/frequency line distortion. RANK-BUSH MURPHY Ltd. 9 July, 1965 [9 July, 1964], No. 28329/64. Headings H3T and H4R. The amplitude/frequency characteristic of a signal is varied by feeding it in parallel to two transistors whose relative mean currents gain are variable by means of a direct potential, and applying the transistor outputs to the two ends of a delay line, one end of which is unterminated and the other end of which is terminated by its characteristic impedance. In Fig. 4 the input signal passes via transistor 2 to one end of the line 11 and via transistors 5 and 23 to the other end of the line. At the frequency for which the line provides a delay of 180 degrees the signal inverted by transistor 23 will be in phase with that which has passed along the line, and the overall gain for this frequency will be increased. By omitting the inverting transistor 23 the two signals will be out of phase and the gain will be reduced at the same frequency. The shape of the overall amplitude/frequency characteristic is stated to be a cosine function. The output is taken through an emitter-follower 33. The amount of variation of gain with frequency is varied at 8 by the base bias on transistor 5. The peak on the amplitude/frequency curve can be shifted by tapping into the line with switch 31. The invention may be used for balancing the characteristics of signal channels whose outputs are combined, e.g. in multi-path communication systems and in recording systems using a plurality of transducers in succession.

Filed: 1949-11-07
Abstract: 665,423. Spray-producers. DEHN, S.G. (Sunbeam Corporation). Nov. 7, 1949, No. 28481/49. Class 69 (iii). The reaction of water leaving orifices 30-33 in tubes 27, 28 rotates the sprinkler head 25 which in turn, drives through reduction gearing, rollers 51, 52 which grip between them the water supplying hose 21. A rear wheel 53 engages the hose and guides the machine therealong. Means for cutting off the water supply when the machine reaches a predetermined position, includes a valve 110 held in the open position by a spring- controlled lever . 123 engaging an annular ledge 121 of the valve and connected to a trip rod 130. When reaching the required position. a member 135, Fig. 1, forces the rod rearwardly, and a spring 116, Fig. - 3, forces the valve upwardly against a seating 97 to prevent the water flow to the sprinkler head via a hollow rotatable stud 26. By forcing the head downwardly the valve is re-engaged by the lever 123. The direction of the spray and hence the distance covered by it is adjusted by rotating a member 40 which turns the tubes 27, 28 about their axes. The roller supporting shaft 72, driven through gearing by the sprinkler, carries compression springs forcing the ridged curved parts of the rollers against the hose, and wheels 70 keep the upper ends of the rollers apart. In a modification, Fig. 8, the water supplied at 151 passes to the sprinkler head through radial channels 160 in the rotating stud 155, and the supply is cut off when a rod 190 engages an obstruction such as 135, Fig. 1, which forces the rod rearwardly so as to disengage it from a latch 193, and allows a spring 196 to lift the rod and the sprinkler head and close valve seatings 163, 164. In a further embodiment a reduction gearing drive to one hose gripping roller is described. Specification 549,456 is referred to.

Class 100(4) In an apparatus of the type in which a character is formed by the relative movement between the ends of a group of wires, the wires 20 are held in a group and movable towards and away from a recording material so that the selectively displaced wires undergo impact with the recording material to effect printing impression, perforation or embossing. As shown the wires 20, in their flexible tubes 22, are held by a clamping screw 105 in a printing head 24 vertically slidable on studs 108 fixed on a member 106 which is slidable transverse of the record material 14 so the printing head 24 may be dispersed in different printing positions with respect to the record 14. The head 24 is moved to effect impression by a flexible drive wire 128 actuated by a cam mechanism 148, 150, and a lever 132, whose action is adjustable by the device 138, 140, 142, 144. The setting of the wires 20 is under the control of electromagnets A-F and a longitudinally and rotatively settable control bar 32, in a manner described in Specification 729,064. The control bar 32 is moved to set the wires by the action of cams 60, 61 on a frame 30 and restoration is by a bail 84, controlled by a cam 94 so that it moves rightwardly with the setting action, so as to prevent overthrow, and leftwardly after printing, to restore the wires to original position. Movement of each print wire is at all times limited and stabilized by heavy slugs 74 slidably carried in a fixed guide housing 26.

Abstract: 1,055,947. Thermal insulation. SULZER BROS. Ltd. July 6, 1965 [July 6, 1964], No. 28634/65. Heading F2X. [Also in Divisions E1 and F4] Extensible sheet material is so formed as to have edges 2, Fig. 1, bounding oblique-angled parallelogram surfaces 3 which are inclined relative to the general plane 4 of the material. The surfaces 3 may be formed by rhombs having acute and obtuse angles meeting at corners 5 and 6, respectively. When tension is exerted in direction X, the panel shortens in direction Y, the distance between the planes containing the corners 5, 6 respectively, remaining substantially the same. The surfaces 3 may be formed by rhomboids with two acute and two obtuse angles meeting at each upper and lower corner of the sheet which then, expands in directions X and Y when subjected to tension in direction X. A rigid sheet which may be used as a supporting structure and extends to the same amount per unit length in both directions X and Y has parallelogram surfaces with non-parallel sides of very different lengths the angles of the parallelogram being 60 degrees and 120 degrees and the angle between the parallelogram surface and the general plane of the material being 45 degrees. In Fig. 6, extensible panels 15, 16 formed of rhomboids 19 of equal size are connected to each other at right-angles by equilateral triangles 17 and by a seam 18 which cannot be forced out of position by compression in direction Y. In a further modification, the seam is eliminated by the provision of a strip 20 (Figs. 7 and 8, not shown). The sheets may be made by pressing, drawing or rolling or by making thin depressions and subsequently telescoping the sheet to produce the folds which may be slightly rounded instead of sharp. The sheets may be connected to flat articles by a transitional zone in which the parallelogram surfaces gradually become smaller. The casing behind the tube wall of a steam generator having superatmospheric pressure in the combustion chamber may be lined with the material, mineral wool being provided in the space behind the material and thin anti-radiation sheeting in the space between it and the tube wall.
