Title: Improvements in indicators and warning signalling devices for indicating the direction of motion of rotation of ships' propellers
IPC: G01P13/04
Filed: 1922-03-21
Abstract: 198,483. Grimmett, A. J. March 21, 1922. Revolution-direction indicators.-In apparatus for indicating the direction of rotation of ships' propellers, contacts are controlled by two gear wheels, one driven by the engine and the other meshing with the first and having some axial play so as to he moved to close different contacts according to the direction of rotation. As shown in Fig. 1, a spiral or helical wheel A is driven by the engine through a clutch, flexible shaft, &c. and gears with a similar wheel B having axial play. When the engine is working, contact spring G or H is forced into contact with member D or E according to the direction of revolution so as to light lamp I or J. To provide a means for counting the revolutions, the lamp circuit is interrupted once in a revolution of the wheel B by projections N co-operating with fixed projections O. In a modification, the direction of revolution is indicated by means of a pointer rotated by a fluid such as oil circulated in a closed cycle by a pump driven by the engine.

Title: Improvements in or relating to the manufacture of transparent cellulosic sheets and films
IPC: C08J7/04
Filed: 1936-03-18
Abstract: Cellulosic sheets and films having improved resistance to the effects of low humidity and having good surface properties are made by incorporating in the sheet or film such a high proportion of softener as would normally cause surface tackiness and adhesion, and applying to the surface an aqueous suspension or emulsion which comprises predominantly a soap and/or a wax, with or without a smaller proportion of a resin.  The proportion of softener, which is preferably glycerol, may be from 15 to 25 per cent of the weight of the sheet or film.  In a modification, there is applied to cellulosic sheets to increase their slipperiness one over another, an agent which comprises predominantly a soap, with or without a normally solid wax, and with or without a smaller proportion of a resin.  The process is applicable to sheets of regenerated cellulose and to sheets obtained from aqueous cellulosic dispersions including cellulose ethers such as glycol cellulose, lowly substituted methyl and ethyl cellulose, cellulose glycollic acid, cellulose phthalic acid, and lowly esterified cellulose esters and ether-esters. Suitable soaps are sodium and potassium stearates, oleates, laurates, and ricinoleates, triethanolamine soaps, sodium sulphuric acid esters of stearyl, oleyl, lauryl, cetyl and myristyl alcohols, and sodium petroleum sulphonate.  Waxes specified are hydrogenated oils, higher fatty acids, wax-like fatty acid esters; higher alcohols, paraffin wax, montan wax, and shellac wax, and suitable resins are natural shellac, cumar resin, rosin, and sodium salts of abietic acid. The anti-sticking agents may be applied together with or after the softening agent.  A number of examples are given.  Specification 472,265 is referred to.

Title: Improvements in selecting systems particularly adapted for controlling a plurality of electric motors
Inventor: PRIEST HAROLD
IPC: H02P1/58
Filed: 1960-03-14
Abstract: 906,136. Control of several motors. HOPKINSONS Ltd. Feb. 28, 1961 [March 14, 1960], No. 8840/60. Class 38 (3). Relates to a system for automatically controlling the operation of a plurality of electric motors for actuating sootblowers, any number of which may be selected for operation, the motors being energized in a predetermined sequence. The system comprises a programme store unit PS with a number of selector switches arranged in columns and rows so that the operator closes those switches which are appropriate to ensure the operation of a master valve and to select those section valves and sootblowers which are to be actuated. A push-button PBS is pressed to bring stepping relays Y and X to their first positions, a master relay Z then operating to complete a circuit for relay M11 so that motor E is connected in series with saturable reactor SR. The control winding of the reactor is afterwards excited, the motor E driving a section valve to its fully-open position, whereupon the control winding is de-energized to stop the motor. This is followed by the de-energization of relay M11 to drop the master relay Z thereby permitting the stepping relay X to move to its second position whereupon the relay Z is again actuated. A second motor relay M12 is then energized to connect motor A to the saturable reactor which is afterwards saturated for full energization of the motor, so actuating a master valve. When this valve reaches its crack position, the reactor is desaturated to stop the motor A. At this point, a drain valve and the section valve are opened whereby low-pressure steam is supplied to a blower head valve. Closure of the drain valve prepares the relay X for the next step, the master valve being driven from the crack position to the fully-open position at which the motor A is stopped. The relay Z is then de-energized and the relay X steps to its third position to pick up the master relay. Relay M13 is energized, the motor F driving a sootblower towards its fully-projected position at which the motor is stopped and reversed by relay RR until the sootblower is fully retracted. Further stepping of the relay X to its eleventh position energizes relay C to move the relay Y one step, whereupon the relay X returns to its first position. Relay M21 is energized and motor E is reversed to close the section valve. Relay X is stepped to its second position in which relay M22 is energized and motor A closes the master valve. When the relay X reaches its third position, the system is prepared for another cycle of operations. The number of selector switches in the programme store may be increased in relation to the number of sootblowers to be actuated.

Abstract: 695,905. Photographic process. FARBENFABRIKEN BAYER. April 16, 1951 [April- 15, 1950], No. 8855/51. Class 98 (ii). Photographic positive silver images are produced by developing an exposed silver halide emulsion layer in close contact with a receiving layer containing development nuclei in the presence of a silver halide solvent and a mercaptotetrazole, e.g. 1 - allyl - 5 - mercapto - 1 : 2 : 3 : 4 - tetrazole and 1 - phenyl - 5 - mercapto-1:2:3: 4-tetrazole. The emulsion and receiving layers may be carried by supports of paper, cellulose acetate or nitrate, or polyamide, or a strongly hardened receiving layer coated on a support may be overcoated with an unhardened or slightly hardened emulsion layer removable in hot water. The emulsion may be a silver chloride or chlorobromide emulsion. The developing agent and the silver halide solvent may be incorporated in the alkaline developing solution, or at least one may be incorporated in the emulsion layer or in the receiving layer or in both of them. The mercaptotetrazole may be incorporated in the emulsion layer, the receiving layer, or the developing solution, or in more than one of these. The binders for the emulsion and receiving layers may be gelatine, a non-gelatine colloid, or a mixture of both. Positive silver images may be produced in receiving layers coated on both sides of a support. For use in reflex printing, a support may be coated on one or both sides with a receiving layer containing a dispersion of opaque colloidal particles (e.g. colloidal zinc oxide) removable by the developing bath or a separate bath and with a silver halide emulsion layer. In an example, an exposed silver chlorobromide emulsion on a paper support and a receiving layer of gelatine containing colloidal silver and 1-phenyl-5- mercapto-1: 2: 3: 4-tetrazole on a paper support are both impregnated with an aqueous developer containing hydroquinone, sodium sulphite, sodium hydroxide, hypo, and potassium bromide and are pressed together for about 1 minute.
