Abstract: 793,525. Heat exchangers. IMPERIAL CHEMICAL INDUSTRIES, Ltd., and WARD, T. H. May 20, 1955 [May 21, 1954], No. 14970/54. Class 64(3) In a heat exchanger, e.g. a radiator or oil cooler comrpising a plurality of plates separated by spacing means and defining therewith fluid pasages at least some of which are connected to header tanks, each header tank is bonded by a lap joint 30 (Fig. 3) to bent-up terminal portions of spacing elements 3. In the apparatus shown, the elements 3 are of channel-shaped crosssection, are disposed in alternate spaces between the plates 1 and define therewith passages 28 extending at right angles to and alternating with other passages 26 which communicate with headers 25, 27. Each passage 26 is defined by a pair of the plates 1 spaced apart by a re-entrant flange 21 extending along one edge of each plate (see Fig. 2). The side walls 7, 9 of each spacing element 3 are bonded to neighbouring plates 1 and the end walls or terminal portions of the element, e.g. as indicated at 13 in Fig. 3, are each secured by the aforesaid lap joint 30 to the header tank.

This central finger moves beneath the covering strips but two stroking arms 10 on the slider move along the top of the covering strips. The front faces of the elements slope down towards the stringer tape.

[Also in Group XXXVII] A dashpot 65 for controlling an electric circuit breaker (see Group XXXVII) and immersed in oil in the breaker tank comprises a discharge valve 120 biased by a spring 127 towards a seat 122 and movable to the open position by a rocker 128 engaging the valve stem 121. The rocker is operated by a cam 129 fast on a shaft 69 a lever 68 fast on the shaft being operated by a cam member 70 pivoted at 71, clockwise rotation of the cam 70 permitting the valve to close. Thus if the valve is closed, downward movement of the piston 66a is controlled by a port 131, whereas if the valve is open no delay is imparted to the piston. Upward movement of the piston is controlled by a port 133. To permit free passage of oil into the dashpot on downward movement of the piston, ports 136 are provided closed by a disc 137 biased by a spring 138, this disc moving down on downward piston movement. In a modified dashpot, Fig. 5 (not shown), the lower end of the dashpot has a further discharge valve which opens automatically under excess pressure ; also, the valve stem 121 is hollow and the spring 127 situated inside.

May 21, 1930, No. 15600. Convention date, June 11, 1929. [Class 40 (iii).] In a television receiving system in which the picture elements are reproduced on a screen two or more times from a single set of received signals applied to an appropriate number of receiving lights sources with a time interval between successive reproductions of the same elements, the picture reproducing points from the different light sources are arranged to move across the receiving screen in the same direction. The picture signal output of an amplifier 3 is applied to a glow lamp 1, and, at a later time, to a glow lamp 5 with a delay corresponding to half a revolution of an aperture or lens disc 11, and produced by a delay arrangement 7. A lens system 17 co-operating with the lamp 5 is arranged so that scanning picture points 19, 21 move in the same direction across the receiving screen 9. In modified arrangements signals of all frequencies are applied to the lamp 1 and the low frequency components only are applied to the lamp 5, or, as described for Fig. 2 (not shown), the components of high and low frequencies are applied to the lamps 1, 5 respectively. The lens or aperture disc 11 may be replaced by a drum disc or a mirror disc. Specification 311,353 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the scanning device may be a vibratory reflecting member which is vibrated in two planes at right-angles to each other.

Filed: 1936-06-04
Abstract: 476,179. Valve amplifying circuits. REDIFFUSION, Ltd., and ADORJAN, P. June 4, 1936, No. 15638. [Class 40 (v)] A valve amplifier operating on a curved part of its characteristic has its anode supply voltage reduced at low signal input by means of a variable-impedance valve the grid voltage of which is determined by the rectified signal voltage. The variableimpedance valve V3 is connected in the plate supply circuit of the push-pull pair of amplifying-valves V1, V2. The grid of the valve V3 is biassed by the voltage arising across a resistance R1 when the signal is applied thereto through a rectifier R. When there is no signal, the impedance of the valve V3 is high, and the heat dissipation in the valves VI, V2 is small. As the signal strength rises, the impedance of the valve V3 is reduced. The valve V3 is shunted by a condenser C1 and a resistance R2. The condenser C1 byepasses signal frequencies, and the resistance R2 shunts part of the direct supply current and enables the variation in the voltage drop in the supply rectifier and smoother to be compensated.

Filed: 1942-11-11
Abstract: Easily soluble therapeutic compounds are prepared by reacting a 2 - sulphanilamido-1 : 3 : 4-thiodiazole which is substituted in the 5-position by an alkyl or an aryl group, with ammonia or an aliphatic amine.  The amount of ammonia or amine added is preferably such as to bring the pH of the resulting solution in the range 7.0-7.4.  The concentration of the solution is preferably arranged such that the resulting solution is of about 4 per cent strength in which case it is suitable for application to the eye or to mucous membranes.  If a more dilute solution than 4 per cent is used, an addition of neutral salts may be made to bring the total concentration of salts to the point where the solution is isotonic with body fluids.  In examples: (1) To 2-sulphanilamido-5-methyl-1 : 3 : 4-thiodiazole (5.5 grams) is added aqueous ammonia to form a solution of pH 7.05.  (2) Ammonia is added to the 5-ethyl compound to form a solution of pH 7.2-7.5.  (3) Monoethanolamine is added to 2-sulphanilamido-5-methyl-1 : 3 : 4-thiodiazole to form a solution of pH 7.2-7.4.

Abstract: 594,031. Locking nuts. DZUS, W. June 22, 1945, No. 15993. [Class 89 (i)] A self-locking nut or similar threaded member has an extension in the form of a collar 14 which may be separate from the main part 12 of the nut and is slotted and tapered in thickness towards the outer end to permit deformation into arcuate longitudinal form with the point of minimum diameter at an intermediate position 17. The resilience may be increased by a helical spring 18. In the contracted position the edges of the segments adjacent the slots 16 do not bear against the threads so that the nuts may be used on coated bolts, such as those cadmium plated, without damaging the surface. In a modification, the minimum diameter may be adjacent the outer end. The invention may be applied to linkwork such as that shown in Fig. 7 where a threaded rod 23 screws into a sleeve 21 and a stud 24 into a boss on a link 19.
