Abstract: 987,724. Moulding lampshades. WARD & GOLDSTONE Ltd. March 18, 1964 [April 3, 1963], No. 13131/63. Heading B5A. A lampshade is formed from a pleated tubular blank 16 of a thermoplastic material, e.g. stiff polyvinylchloride, by placing the blank over a hollow stem 5, between a fixed concave former 9 and a slidable concave former 10, heating the blank, and then moving member 10 towards member 9 to force the heat softened blank outwards into contact with the formers as in Fig. 3.

Title: Amplifier for television system
IPC: H04N5/265
Filed: 1938-05-03
Abstract: 517,666. Television; valve amplifying circuits. PHILCO RADIO & TELEVISION CORPORATION. May 3, 1938, No. 13157. Convention date, May 25, 1937. [Classes 40 (iii) and 40 (v)] A video signal amplifier has its gain varied by a control signal and by manual means and is so arranged that the control signal together with any component thereof is eliminated from the output. The control signal may be a blanking out signal and a synchronizing signal may be combined with the amplifier output during the blanking out period. A composite signal amplifier may effect the combination and may be fed from a plurality of video signal amplifiers with common manually operable gain control means to provide a fade-over control. The Figure shows an amplifier which provides blanking out and fading control comprising identical valves, V1, V2, an auxiliary valve V3 and a phase inverter V4. In this way the output across the common load resistance R2 is unaffected by the gain control signal. The input signal may be applied only to the valve VI or to both V1, V2 in push-pull and the blanking-out signal to the valve V3 so that the common cathode resistance R1 reduces the gain of both valves VI, V2 to zero. Gain control by varying the bias applied to the valve V3 may be from a remote point and the time constant of the circuit RC is preferably such that the control is only effective in an appreciable interval. The gain or fading control may be effected by directly varying the bias of valves V1, V2 and the time of fade in may be different from the time of fade out. Specification 493,289 is referred to.

The cable arrangement 11 is controlled by a cable 14 wound one way on a larger drum 15 of the winch 16 while the cable arrangement 17 is controlled by a cable 23 wound the other way on a smaller drum 26 of the winch 16. Thus, when the jib 5 is raised it contracts and when lowered it extends. A desired track for the load hook 27 can be obtained, for example substantially horizontal, Fig. 3 (not shown), by varying the ratio of the diameters of the drums 15, 26 and the number of falls in the cable arrangements 11, 17. The load hook 27 is supported by a cable 28 wound on a separate winch drum 33, independent of the winch 16, which may be operated simultaneously with the winch 16 to vary the trajectory of the load hook 27, if desired.

[Also in Division H1] An aperiodic high frequency amplifier is provided with negative feedback by means of a pair of capacitors 6, 7, Fig. 1, which include, and may comprise only the valve capacitances, connected in series across the output and with the grid connected to their common point. Capacitors 6, 7 form, together with a pair of inductors 8, 9 also connected in series across the output, a balanced bridge network, points a, b being at the same potential. Inductor 9 comprises the outer of a length of coaxial cable, the inner conductor of which is connected to point a to supply signal to the grid; the output signal does not appear on this conductor, owing to the balanced nature of the bridge network. A screened resistor may be connected between points (a, b), (Fig. 2, not shown), to terminate the cable, and where the latter is short and may be regarded as lumped capacitance it may be built out with series inductance at both ends: inductance may likewise be added between the point (a) and the cable end corresponding to compensate for the capacitance 7. In a pushpull modification, Fig. 3, a transformer is used, the centre-tapped main winding 18 of which is connected between the valve anodes, while the grids are fed over two auxiliary windings 17, 17<SP>1</SP> each of which comprises a length of concentric cable.

An additional coil SP1 or a permanent magnet may be used with the coil SP. Condensers Ci, Ce shunt the resistance W and coil SP. The double-sided cathode K is surrounded by a split anode 81, S2, connected to an adjustable Lecher wire system. By using large condensers the stabilization is made sluggish. Curves with description are given to explain the working.
