Title: Improvements in or relating to amplifier circuits
IPC: H03F1/36
Filed: 1951-01-08
Abstract: 687,683. Valve amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 8, 1951 [Jan. 11, 1950], No. 523/51. Class 40 (vi). In a multi-stage amplifier in which an impedance in the cathode circuit of the output valve has produced across it a negative feed-back voltage, which is applied to at least one preceding stage, a Wheatstone bridge circuit is connected between the penultimate and final stages so that distortion produced by that component of the current flow through the cathode feed-back impedance which is caused by the input capacity of the output tube is substantially eliminated. The Figure shows in schematic form a three-stage amplifier in which negative feed-back is produced by feeding back the voltage produced across the impedances Za, Zb in the cathode circuit of the output valve 5 to the grid-cathode circuit of the first valve 3, The impedances Z3, Z4, Za, Zb constitute a Wheatstone bridge circuit and are such that Za : Z4=Zb : Z3, thus the current flow into Zb via the input current flow into Zb via the input impedance Z4 is compensated for by the current flow into Za via the impedance Z3 so that the current flow through the feed-back impedance Za, Zb is proportional only to the current flow in valve 5. Preferably the impedances Z1, Z2 should also fulfil the bridge relationship Za : Z2=Zb : Z1.

Abstract: 1321582 Aerials; radio signalling SUMITOMO ELECTRIC INDUSTRIES Ltd 6 Jan 1971 [26 Jan 1970 1 Feb 1970] 615/71 Headings H4A and H4L A leaky coaxial cable has in its outer conductor a radiating slot array in which each slot is arranged periodically at a fixed axial interval, or integral multiple thereof, and in which the shapes or sizes or other radiation factors of the slots are changed discretely from one slot to another in another periodicity. A substantially sinusoidal variation of radiation intensity is obtained along the cable, a plurality of slots being comprised in each half of said other periods. As described, a leaky coaxial cable comprises an inner conductor 1, and an outer conductor 2, equal length straight slots 4 1 , 4 2  ... &c. being cut in the latter at regular pitch intervals p 0 . In order to obtain a substantially sinusoidal distribution of radiation intensity over each section p of eight pitch intervals p 0  the slots therein are rotated by discrete amounts one after the other. Thus, considering the slots 4 1  to 4 9 , the slots 4 1 , 4 5 , 4 9  corresponding to zero values of radiation intensity are parallel to the axis of the cable. The slots 4 2 , 4 7  are rotated by maximum amounts in opposite senses, corresponding respectively to the positive and negative maxima of the said sinusoidal distribution. The slots 4 2 , 4 4  and 4 6 , 4 8  are similarly rotated, by lesser amounts. In a second embodiment the ineffective slots 4 1 , 4 5 , 4 9  are omitted (Fig. 5, not shown) and this applies for the equivalent slots in all other embodiments. In a third embodiment straight slots which are equally inclined to the axis but which have different lengths are used (Fig. 6, not shown), and in a fourth embodiment straight slots having differing lengths and inclinations are used (Fig. 7, not shown). A fifth embodiment features the use of folded line-shaped slots having portions 5, 6, Fig. 8, respectively perpendicular to and parallel to the axis, and of differing sizes, to obtain the required sinusoidal distribution of radiation intensity. In a sixth embodiment folded lineshaped slots of differing sizes are also used, but are angularly displaced by differing amounts relative to the axis (Fig. 9, not shown). It is stated that the cables described have broad hand characteristics particularly suitable for vehicular communication systems.

Abstract: 906,589. Photographic printing from a luminescent screen. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 1, 1959 [Jan. 9, 1958], No. 880/58. Class 98 (2). In apparatus in which image forming radiation excites a luminescent screen, the luminous image formed is modified by a like image formed on the screen by quenching radiation and the modified image is contact or projection printed on to light-sensitive material. The two images may be formed by episcopic or, preferably, by diascopic projection. As shown, mercury vapour ultra-violet and infra-red radiation sources 3 and 4 form coincident images of photographic negative 2 on a zinc sulphide luminescent screen 7 carried on a support 6. The intensities of the sources 3 and 4 are adjustable so as to vary the contrast of the luminous image which is contact printed on to a bromide paper 9. The screen 7 carries a protective layer 8 which may be in the form of a ultra-violet absorbing layer. For sharp masking, the negative 2 may be placed in contact with the support 6 or alternatively the lens 5 may be designed to focus sharply both the ultra-violet and the infra-red images. For unsharp masking, a conventional enlarger lens may be used and focused for the ultra-violet image. The ultra-violet range may be extended by using a quartz lens. The luminescent material may include cobalt, nickel or iron and be activated by copper or silver.
