Title: Interlocking control means
Inventor: POLLARD LEONARD ARTHUR
IPC: F16P7/00
Filed: 1958-01-30
Abstract: 848,824. Change-speed and clutch control; locking rotary elements. TRIANCO Ltd. Jan. 20, 1959 [Jan. 30, 1958], No. 3190/58. Classes 80 (2) and 80 (4). A shaft 1 is prevented from rotating beyond a predetermined angle by abutment means 5a, 5b which are disengaged by hydraulic pressure on pistons 9a, 9b at a predetermined value of the pressure, the fluid system being controlled by initial rotation of the shaft. Initial movement of the shaft 1 controls the admission of fluid pressure to pressure-operated clutches for " Ahead " or " Astern " drive of a propeller shaft, and subsequent rotation controls the engine throttle. When the shaft is rotated initially the appropriate clutch is engaged and the shaft is restrained by the abutments 5b, 7b; as.the clutch engages the fluid pressure in the system rises and is led through timing restrictor 13b to act on piston 9b. At a predetermined pressure the force on the piston 9b overcomes the spring 4 and releases abutment 5b to allow further rotation of the shaft to open the engine throttle. On closing the throttle the system is unloaded rapidly through a spring-loaded checkvalve 14a.

Patent GB-489117-A (GB)
Title: An improved method of and apparatus for the quantitative analysis of a mixture of gases
IPC: G01N7/02
Filed: 1937-02-08
Abstract: <PICT:0489117/III/1> A gas mixture is passed at substantially constant temperature and pressure through a succession of transparent calibrator tubes separated from one another by absorbers for extracting individual constituents of the mixture, and the rate of flow through each calibrator is measured by timing the passage along the tube of a soap film introduced therein.  The film is destroyed at the end of the tube by electrolysis, a chemical reagent, or mechanical means.  The Figure shows a single absorber 33 situated between two calibrators 26.  The gas is introduced at 10 under a constant pressure determined by a liquid seal 13 containing a liquid of low vapour pressure such as butyl phthalate.  The soap films are produced by raising the solution contained in tubes 17 into the gas current by rotating Archimedean screws 24; their passage between calibration marks 41, 42 is timed, and they are destroyed by contact with glass spirals 28.  The absorber contains a fixed helix of glass rod 34 down which absorbent liquid flows from a nozzle 35.  An alternative method of forming the soap films consists in raising them into the gas current on a wire loop on which it has previously been formed.  The Provisional Specification is not restricted to the use of soap films and includes all methods of measuring the velocity of flow before and after each stage of absorption.

Abstract: 538,771. Optical sound recording. RADIO CORPORATION OF AMERICA. Feb. 28, 1940, No. 3695. Convention date, March 31, 1939. [Class 40 (ii)] In recording audio frequencies optically, the high and low frequency components are separated, the low frequency components are recorded as a variable-area track, and the high frequency components are recorded as a variable-density track located in the otherwise transparent part of the variable-area lowfrequency track. As shown in Fig. 2, light passes from a lamp 15 through lens 16, masks 17, 18, lens 19, 20 to mirror 21 of galvanometer 29, and thence through lens 22, mask 23 and lens 24 to film 25. Mask 17 has two apertures 27, 28 producing penumbras which are oscillated over slit 26 of mask 23 by galvanometer 29 energized by the high-frequency components of the sound, whereby the variable density pushpull tracks 13, 14, Fig. 1, are formed on the film. Mask 18 has a single aperture and is actuated by coils 30, 31 energized by the low-frequency components of the sound, thereby producing the variable area push-pull tracks 10, 11. In another arrangement, the variable area track is produced by a three-ribbon light valve close to a double slit in a mask. In still another arrangement, both tracks are produced by means of mirror galvanometers, one preceding the other. " Ground-noise " may be reduced by varying the amplitude of one track, in which case volume compensation is required for the other track.
