Title: Improvements in carburettors for internal-combustion engines
IPC: F02M19/08
Filed: 1939-05-17
Abstract: 528,939. Spray carburetters. WHITEMAN, J. L. May 17, 1939, No. 14772. Convention date, May 27, 1938. [Class 7 (iii)] Fuel is metered and discharged through a central passage in a suction-actuated air valve which opens into a mixing chamber with helical projections on its walls for whirling the charge. A suction-actuated air inlet valve 13, supported by a spring 14 the tension of which is adjustable by a rack 35 and pinion 38, closes the entrance to a mixing chamber 2 and is bored axially for the passage of fuel which is metered by a needle valve 16. This valve is carried by a forked lever 26 controlled from the dashboard and normally used to make the setting of the valve appropriate to the fuel used, but adapted to depress the needle valve to close the fuel passage and then on further movement to open the valve 13 to admit air to the engine during overrunning. A spring 32 holds the head of the needle valve 16 against a pin 30 adjustable by a screw 31 or otherwise. The valves are mounted in the leg if an L-shaped bracket 24 and the upper face of the valve 13 is coned to di ect the air stream over the walls of the mixing chamber 2, opposed spiral ribs 19, 20 on the walls producing turbulence by directing this stream at an angle on to the stream which has traversed the centre of the chamber as the streams pass through the outlet 37 of the chamber. The fuel may be aerated by air drawn through passages 33 in the valve 13, these passages also providing the air necessary for idling when the valve 13 is closed.

Title: Improvements in colour photographic processes and materials
IPC: G03C7/18
Filed: 1949-06-02
Abstract: 668,642. Colour photography. KODAK, Ltd. June 2, 1949 [June 2, 1948], No. 14781/49. Drawings to Specification. Class 98 (ii). To produce a multicoloured record incorporating a colour-correction mask a film has three superimposed silver halide emulsion layers sensitive respectively to the red, green and blue regions of the visible spectrum and containing colour couplers adapted on colour development to give colours complementary to the sensitivities of the emulsion layers, the bluesensitive layer not being between the red and green-sensitive layers, and there is present between any two of these emulsion layers a silver iodide emulsion layer. The iodide emulsion is not light-sensitive and is prepared very simply by reaction of silver nitrate with potassium iodide and the other emulsions may be those of Specification 541,589. In a preferred form the film has a yellow filter layer of dye or colloidal silver beneath the blue-sensitive layer and the silver iodide layer beneath this, and this film is exposed in a camera to a coloured subject, colour developed, treated in a stop bath, bleached, fixed in hypo ; and is then exposed to white light through the originally red and green sensitive layers after a sensitizing treatment for the silver iodide layer with sodium sulphite or sodium carbonate, developed in a high energy (hydroquinone) developer to produce the mask in the silver iodide layer and fixed in an ammonium thiosulphate bath to remove residual silver iodide. The masked colour negative so produced may be printed on to a similar sensitive material but not provided with the iodide layer and which may have a paper base to provide, after processing, a picture which duplicates the coloured subject. The silver iodide emulsion layer may, if desired, be incorporated in the yellow filter layer, or may lie between the red and green-sensitive layers which themselves may be in either order; or it may contain colour couplers and may be subjected to, development with a high energy coupling developer, or coupler may be added to a high energy developer used for developing the mask, and in these cases the silver may be removed so as to provide the mask in colour, such as yellow. No substantial latent image development is effected in the iodide layer by the first developer and the iodide is not fixed out by the hypo in the time required to fix the light-sensitive layers. Specifications 524,557, 541,298, 561,674 and 577,804 also are referred to.

Title: Electric signal transmission systems
IPC: H04B3/00
Filed: 1939-05-19
Abstract: 529,011. Wide band transmission. STANDARD TELEPHONES & CABLES, Ltd. May 19, 1939, No. 14983. Convention date, June 11, 1938. [Class 40 (iv)] [Also in Group XL] In a system for transmitting a wide frequency band in which a carrier of a frequency greater than or equal to the highest frequency is modulated with the lower frequencies and is transmitted simultaneously with the higher frequencies, the amplitude and phase relations of the combined waves are so adjusted that the resultant envelope curve reproduces in one half the original wave form. The transmitted signals can therefore be reconstituted by the use of a simple detector at the receiver. As shown, the lower frequencies pass through a filter 3 to a modulator 10 and thence through a band-pass filter 12 to an output valve 13. The whole band is fed through a valve 1, delay network 2 equivalent to the filter 3 and a valve 4, and a valve 5 fed by the filter 3 is adjusted to neutralise the lower frequencies in the output of the valve 4, which supplies a phase-inverting output valve 7 through a delay network 6 equivalent to the filter 12. It is shown that if the amplification of the valves 7, 13 is suitably adjusted in relation to the depth of modulation produced by the modulator 10, the envelope of the combined output waves is of the form shown in Fig. 7, in which the lower half corresponds to the original signal. At the receiver, therefore, the signal wave passes through an amplifier which produces a phase reversal to a linear detector, and thence to a demodulator.

Abstract: 612,294. Extracting tobacco from rejected cigarettes. LEGG, O. May 23, 1946, No. 156,66. [Class 130] In a machine for extracting tobacco from rejected cigarettes, the cigarettes are arranged upwards from a hopper by a conveyer 2 to longitudinal channels in a shoot 3 and thence to a conveyer 6 over which they pass by gravity beneath rotary knives 8 which rip open the cigarettes lengthwise and pass the tobacco and papers to a rotary tubular sieve 9 through which the tobacco passes to discharge belt 11 while the papers are retained by the sieve and discharged from the lower end thereof. The conveyer 2 may be driven by a separate motor and comprise a belt fitted with cross slats 21. The shoot 3 has longitudinal channels into which the cigarettes are deflected by camshaped members 22 spaced across the shoot and extending through the base thereof. The members 22 are coupled by rods 23, 24 to a shaft carrying a hook member 26 secured to a hammer 27. The latter coacts with a pin on a sprocket wheel 28 so that at each rotation of wheel 28 the hammer is caused to strike the base of the shoot and the members 22 are actuated to assist in arranging the cigarettes horizontally on the shoot 3. From the rotary knives 8 the tobacco and cut papers are delivered down shoots 34, 35, to the sieve 9 mounted in a casing 39. Tobacco passing through the sieve falls on to a reciprocating sieve 10 which allows the tobacco to pass to the belt 11 and discharge shoot 12. Paper from the sieves 9, 10 passes down shoots 14, 15 respectively to sieve 13 which is vibrated by a cam. Any tobacco still adhering to the paper is thus separated and passes along shoots 50 and 51 to a hopper 52 connected to a blower 16 and discharge pipe 17. Another blower removes dust from other parts of the machine. Preferably an electro magnet 74 is located at the end of shoot 3 to remove any metallic substance from the tobacco.
