Title: Improved electric signalling device
IPC: G08B25/14
Filed: 1953-02-05
Abstract: 729,358. Electric signaling . apparatus. ALGEMENE KUNSTZIJDE UNIE N.V. Feb. 5, 1953 [March 5, 1952], No. 3260/53. Class 118 (1). In an electric alarm system comprising a plurality of circuits which when suitably actuated cause respective lamps to light at a central station and also cause a common audible alarm, drawing attention to the lighting of a lamp, to sound, means are provided for restoring the audible alarm circuit shortly after each actuation thereof so that it is available to respond should a further circuit be actuated. The audible alarm is actuated by a relay 9 in the anode circuit of a gas-filled valve 1, the valve being triggered to cause an alarm to sound when any one of the circuit links 15, is broken or when the link 28 is closed, by virtue of the alternating voltage developed across the respective temperature-sensitive resistor 13, the corresponding lamp 27 being simultaneously lit. The resistors 13 have negative temperature coefficients so that after current has passed through one for a short while, the drop in its resistance due to the heating effect of the current passing through it is such that the gas-filled valve is no longer controlled by the potential developed across the resistor 13 and by momentarily opening the switch 7 the audible alarm may be made to cease sounding.

Title: Improvements in and relating to advertising devices
IPC: G09F23/16
Filed: 1924-02-08
Abstract: 234,870. Leon, K. O. Feb. 8, 1924. Illuminating, means for.-A clock mechanism has its characteristic function of showing time periodically interrupted to show advertisemants. A grandfather clock is described in which by optical projection, with the aid of mirrors 24, 25, an advertisement and a shadow of clock hands &c. are in turn shown on a screen b of translucent glass &c. The advertisements may be carried by a disc or a band c, preferably endless, certain links of which, e.g. every third, are blank. The band c passes over a hexagonal roller c driven intermittently from a chain o through Geneva stop mechanism l, k, h so as to position each link in turn in the light beam. The band c is steadied by a slotted guideway 45, preferably of staggered formation. Each advertising transparency is removably held in the band links which are of metal with an opening 39, Fig. 8, the transparency being slipped under flanges 43 and positioned between rides 44. The hands of the clock t, Fig. 2, are mounted at right angles to an extension 11, and may be adapted to be swung into the light beam at the intervals when the blank links are in place. This is effected by pivoting the clock t at u and controlling its gravitational or spring-influenced tendency to raise the hands into display position by a cam p on the shaft g of the roller e. The clock numerals may be marked on the blank transparency of the band on the screen b, or on a ring around the hands. This ring and the hands only are brought into focus, the necessary supporting framework and gear wheels being not reflected. To secure accurate focusing the clock trunnions u have pins which engage oblique slots in their bearings and move the clock laterally to bring the hands when displayed into the plane of the band. In modified forms the clock is stationary and a mirror may be swung into position to reflect the clock hands, illuminated by a second mirror, through the objective. Or the objective and the mirror 24 together, or a single mirror, may be pivoted to transmit light from the band and from the clock in succession. Or the band c may travel horizontally, and each blank link be provided with a mirror arranged to reflect the clock, the remaining links being preferably shielded by an overhanging flange. The spaces between mirrors and lenses may be enclosed by casings. An audible signal may be given and the source of light may be extinguished or masked during each change.

[Class 98 (ii)] A spreading-agent for incorporation in a sensitive emulsion or in any other predominantly aqueous solution of gelatine or other hydrophilic colloid to be applied to a photographic support comprises a water-soluble (sulpho) salt of an aliphatic ester of sulphosuccinic acid. From 0.001-0.5 per cent of the salt by weight may be employed. The sodium or other alkali metal, ammonium, alkylammonium, or alklyolammonium salt may be employed. The salt may be of an alkly or alkyloxyalkyl di-ester of sulphosuccinic acid or of an alkyl or alkyloxyalkyl mono-ester in which the unesterified carboxyl group is present in the free state or in the form of the sodium or other alkali metal, ammonium, alkylammonium, or alkylolammonium salt. A salt of an alkyl or alkyloxyalkyl mono-ester in which the esterifying-group contains from 8-18 carbon atoms or of a di-ester in which at least one of the carboxyl groups is esterified with an alkyloxyalkyl group may be employed. Examples specified are sodium dioctyl sulphosuccinate, sodium diamyl sulphosuccinate, sodium di-(methylamyl) sulpho succinate, sodium dihexyl sulphosuccinate, sodium ethyl lauryl sulphosuccinate, sodium di-n-butyl sulphosuccinate, sodium dicyclohexyl sulphosuccinate, sodium di-(ethoxyethyl) sulphosuccinate, sodium methoxyethyl lauryl sulphosuccinate, sodium p-methoxybenzyl octyl sulphosuccinate, sodium methoxyethoxyethyl lauryl sulphosuccinate, sodium monolauryl sulphosuccinate, sodium monolauroxyethyl sulphosuccinate, or sodium mono-lauroxyethoxyethyl sulpho-succinate. The sensitive emulsion or other solution containing the salt may be applied to the support and set by chilling, and before drying, a predominantly aqueous solution of gelatine or other hydrophylic colloid may be applied over the layer produced. Salts containing at least one hydrophilic group in addition to the sulphonic group must be used in this case, and an increased quantity is preferable. If more than one predominantly aqueous solution of gelatine or other hydrophilic colloid is applied to the support, any or all of the layers may contain the salt. The emulsions are more readily wetted by the developer. Other hydrophilic colloids referred to are water soluble cellulose derivatives such as wellhydrolysed cellulose acetate, cellulose esters of lactic, glycollic, and other hydroxy-monocarboxylic acids, and salts of cellulose esters of dicarboxylic acids such as phthalic acid; polyvinyl alcohol such as hydrolysed polyvinyl acetate ; and watersoluble polyvinyl acetals. The salts may also be used as dispersing agents for the sorbitol monoesters in the process described in Specification 547,632. Specifications 531,579, 536,680, 540,367, 542,703 and 542,704 also are referred to.

Title: Improvements in tank filling valve assemblies
Inventor: JR EVERETT HASTINGS BADGER
IPC: F16K31/34
Filed: 1960-02-01
Abstract: 906,456. Fluid-pressure servomotor-control systems. PARKER-HANNIFIN CORPORATION. Feb. 1, 1960, No. 3542/60. Class 135. A tank-filling valve assembly, particularly for aircraft fuel tanks, comprises a main valve and a pilot valve 40, the main valve having a housing 4 provided with an inlet 5 and outlet 12, a valve member 14 operated by diaphragm 9 which forms one wall of a pressure chamber 32, a restricted aperture 18 connecting the inlet with the chamber and a vent connecting the chamber with the pilot valve, and a pressure relief valve 51 connected by a passage means 26 to the inlet and chamber respectively in order to relieve the pressure in the chamber when a pressure surge occurs in the inlet. As shown in Fig. 3, the main valve, for safety reasons, is provided with a second diaphragm 10 which, together with a cover-plate 7 of the valve housing, forms a second chamber 29 in communication with the inlet 5 by means of a restricted port 28 and passage means 26, 30; the diaphragm 10 acts on the diaphragm 9 via a member 23. The two chambers 29, 32 are connected to their respective pilot valves 40, 41 through pipes 35, 36 and each provided with a relief valve 51. In operation, in the position shown in Fig. 1, in which the tank is full, the pilot valves are closed, thereby permitting a build up of pressure in both chambers via the restricted passages 18, 28 and thereby maintain the valve 14 closed. When the level in the tank falls and the pilot valves open, the pressure in the chambers 29, 32 is vented and thus permits the valve 14 to be opened under then pressure of the liquid so as to refill the tank. In order to prevent a surge of pressure in the inlet 5 at the moment of closure of the valve and a consequent excess build up of pressure in the two chambers, the spring-loaded ball relief valves 51 are fitted. In the modification shown in Fig. 5, applied to a single diaphragmoperated main valve, the ball relief valve 51 is replaced by a diaphragm-operated valve 84, 90 communicating with a chamber 79 by a pipe 92. In operation, any surge in pressure in the inlet 74 is communicated to one side of the diaphragm 84 via port 83, thereby allowing the consequent increase in pressure in the chamber 79 to be relieved through the pipe 92, valve 90 and port 86a. The latter diaphragm relief valve may be used to replace the ball relief valve in the embodiment previously described.
