Abstract: 1391994 Photographic processes FUJI PHOTO FILM CO Ltd 20 April 1972 [20 April 1971] 18461/72 Heading G2C A process for producing a coloured image comprises (i) uniformly heating a material comprising a support having thereon a hydrophilic binder in which is dispersed fine particles of an organic halogen which generates free radicals on exposure and a compound which reacts with the exposed halogen to form a colour and (ii) imagewise exposing to U.V. or visible light, x- or gamma-rays or electron beams. The material may also be subsequently heated if an image does not appear on exposure. The colour-forming compound may be an arylamine, N-vinyl indole or carbazole or a leuco dye. The binder may be gelatine, casein,  starch, gum arabic, carboxy- or hydroxy-methyl cellulose or polyvinyl alcohol or pyrrolidone. The material may also contain a sensitizer (e.g. a dye, an anthraquinone, a metallocene, a hydrasine or an aromatic amine N-oxide), a stabilizer (e.g. a hydroquinone, thiourea or an amide) and an image toner (e.g. a furfurylidene).

Abstract: 1387028 Waveguide filters FERRANTI Ltd 24 April 1973 [25 April 1972] 19108/72 Heading H1W A bandstop filter for a waveguide transmission system comprises an array of identical resonant circuits. As shown, the array is made up of a number of apertured plates or irises, all the apertures having the same width a equal to the width of waveguides 18. Each resonant circuit comprises an iris 12 of height l bounded by two irises 11 of height c where l>c and c<b (the height of the waveguides 18). In addition, two end irises 13 of height m, where m is the mean of band c, forms impedance-matching elements between the array and the waveguides. The resonant circuits are tuned to a harmonic band of the desired pass band of the system, and where it is desired to attenuate more than one harmonic band, a number of arrays with different values of l are used. An iris 11 between resonators in different arrays may be stepped to provide two apertures each appropriate to the adjacent resonant circuit. Alternatively, a single aperture of constant height corresponding to the mean of the two admittances may be used. In a filter designed to attenuate 2fo and 3fo, the part effective at 2fo may be divided into two portions located one on either side of the part effective at 3fo.

[Class 103 (i).] Automatic vacuum brakes for railways comprises a supplementary vacuum reservoir adapted to be connected to the lower chamber of the brake cylinder to accelerate release whilst the vacuum train pipe is isolated from the lower chamber and the supplementary reservoir is isolated from the upper and lower chambers during brake application. In brake application, air from the train pipe 10 acts on an abutment 5 to open a valve 6 and admit this air to the lower chamber 8 of the brake cylinder, simultaneously a ball valve 17 is allowed to close the supplementary reservoir 18. On release, when train' pipe and lower chamber pressure has been reduced a predetermined amount a spring 15 closes the valve 6 and opens the valve 17. The brake cylinder is eventually evacuated through a non-return valve 14 and by-pass passage 13. On one side of the abutment 5 exists the pressure in the upper cylinder chamber or the atmosphere. In the latter case the spring is arranged on the right of the abutment 5. The valve 6 may be replaced by an obturator fitting with slight play in a port.

Title: Self checking means for apparatus for comparing the impedance of two electric circuits
IPC: B61L1/18
Filed: 1948-07-21
Abstract: 642,495. Indicating presence of railway vehicles. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. July 21, 1948, No. 19499. Convention date, Sept. 6, 1947. [Class 105] [Also in Group XXXVI] A relay in the output diagonal of a Wheatstone bridge and released when the bridge is balanced, is arranged so that when released it causes the bridge to become unbalanced so that the relay is then again energized, whereby the unbalancing is removed to drop the relay again, these actions being repeated and the consequent periodic actuation being shown by an indicator. The invention is described with reference to detecting the presence of a vehicle on a stretch of railway track. A loop L, the inductance of which is altered by the presence of a vehicle, is arranged in an A.C. bridge circuit 1, 2, 3, 4 whose output is amplified at V3, V4, V6 and applied to gas-filled valve V5 whose anode circuit is fed with A.C. and includes a direct current relay CF. The bridge is balanced only when arm 4-2 includes a resistor R1 placed in circuit by a front contact b of the relay CF. Accordingly, when relay CF is energized, the bridge becomes balanced to cause the relay CF to drop and thereby to unbalance the bridge to re-operate the relay CF which thus continues in periodic operation. The periodic operation of relay CF controls slow release relays FP, CD to light lamp G. With a vehicle present in the loop L, the bridge remains permanently unbalanced and relay CF thus remains actuated so that while relay FP remains up the relay CD drops, thus lighting lamp R. A fault produced by ageing of valve V5 results in relay CF remaining unenergized and the lighting of lamp R. The resistance R1 is such that the periodic change of potential in the bridge arm is less than that arising on the minimum change of loop impedance required to be detected. The relay CF is made to respond to this smaller change, arising from the periodic action of R1, by adjustment of the cathode voltage on the valve V5. In a modification, the resistance R1 is connected between point 1, 4 instead of 4, 2, Fig. 2 (not shown), but over a back contact of the relay CF and giving an unbalancing effect. The rails 1a, 1b may be connected by low resistances or condensers to reduce leakage of any current induced in the rails through the ballast. The invention is applicable to the detection of movable objects on a road or an airfield..
