Title: Improvements relating to slide valves
IPC: G01F3/22
Filed: 1936-03-04
Abstract: 471,675. Slide valves; gas meters. PARKINSON & COWAN (GAS METERS), Ltd., and BUTTERWORTH, E. March 4, 1936, No. 6576. [Classes 54 and 135] Slide valves such as those used in gas meters are operated by mechanism which varies the path of oscillation of the valve over its seat so that foreign matter thereon is ejected. For this purpose, the valves a, b, Fig. 2, are pivotally connected to connecting rods c, d respectively so as to be rigid therewith for movements in a horizontal plane. The valves therefore experience the angular or " waggle " movements of the rods c, d imparted by a crank-shaft e. The paths of oscillatory movement of the valves are arcuate as shown in Fig. 2, due to the pivotal connection of the valves to their respective links j, k which in turn are pivoted on a fixed pin m. In the modification shown in Fig. 5, the fulcrum pins h, i on the valves engage slots p, q, Fig. 5, in fixed brackets. The slots may have any desired shape, straight or curved, and may be in the valve seats f, g. Alternatively, slots on the valves may engage fixed fulcrum pins.

Title: Stripline antenna arrays
IPC: H01Q1/38
Filed: 1975-02-17
Abstract: 1529361 Stripline antenna array DEFENCE SECRETARY OF STATE FOR 4 Feb 1976 [17 Feb 1975] 6691/75 Heading H4A A stripline antenna array comprises a conducting pattern on a dielectric substrate with a conducting backing, the pattern including strip elements each connected at one end to a point along a feeder strip, the other end being an open circuit termination at which, in use, most of the power is radiated or picked up. In the Fig. 1 embodiment the array comprises five sub-arrays branching from feeder 5. Each sub-array has #/2 long elements 4a-4e spaced # apart along a feeder 3. The elements towards the ends of the feeders 3 are narrower than those near the centres, to provide shading for side-lobe reduction, and in consequence need to be slightly longer than those near the centres (necessitating a slight curvature of feeders 3, as in Fig. 2 not shown) to make their electrical length #/2. Each feeder 3 supports standing waves and is terminated by an open circuit (or a ring resonator, Fig. 4, not shown) #/2 from element 4e. Troughs may be cut in the substrate adjacent the radiating ends of elements 4a-4e (Fig. 3, not shown) to inhibit the launching of surface waves into the substrate. Fig. 5 shows a travelling-wave "fish-bone" array having two sets 54a-54j and 54k-54t of #/2 long elements branching from a feeder 53 terminated by a carbon-doped fabric absorber 58a (or by a matched impedance, Fig. 5a, not shown). The inter-element spacing in each set is # and the two sets are mutually staggered by #/2, whereby plane polarized waves are transmitted or received. For transmitting or receiving circularly polarized waves the two sets would be staggered by #/4 and the elements would extend obliquely from feeder 53, those of one set being orthogonal to those of the other set (Fig. 7, not shown). To reduce the length of array 5 the single elements 54a etc. may be replaced by compact groups of elements (Fig. 6, not shown). The feeder may be of zig-zag form rather than straight (Fig. 8, not shown).

Title: Improved method of producing a covering layer on a film adapted to receive a mechanically - produced record of sound or other oscillations
IPC: G11B11/00
Filed: 1938-03-08
Abstract: An opaque covering layer for films intended for mechanical recording and optical reproduction of sound is provided by forming a metal sulphide in a protective colloid (e.g. gelatine) solution and then increasing the covering power of the mass by further heating, preferably in the presence of a substance in which the metal sulphide particles are soluble.  The sulphide is produced directly in a solution which already contains the protective colloid by adding small amounts of the metal ion and sulphide ion intermittently.  The covering power is then increased by heating in the presence of a substance capable of dissolving the metallic sulphide.  For sulphides of mercury, molybdenum, tungsten and metals of the platimum group, a substance capable of liberating a sulphide ion, such as sodium sulphide in alkaline solution, is used.  For sulphides of lead, iron, nickel or cobalt, a substance capable of liberating hydrogen ions, such as hydrochloric acid, is suitable.  Potassium cyanide may be used to dissolve copper sulphide.  Specification 433,250 is referred to.
