Title: Improvements in devices for controlling the fuel supply of internal combustion engines
IPC: F02M37/00
Filed: 1931-05-01
Abstract: 378,025. Fluid-actuated valves. SOC. GENERALE DES CARBURATEURS ZENITH, 26, Rue de Villiers, Levallois- Perret, Seine, France. May 1, 1931, No. 12932. Convention date, May 1, 1930. [Class 135.] A fuel control valve 3 moves in a chamber 1 having inlet and outlet passages 2, 4 respectively, one element of the wall of the chamber being constituted by a deformable membrane 5 the inner face of which is bathed by the fuel. This membrane is actuated by another membrane 7 subjected to a pressure difference produced by the working of the engine. For example, suction may be transmitted to the chamber 6 through a pipe 12, the outer face of the membrane being exposed to atmospheric pressure. The membranes are loaded by a spring 8 which is sufficiently stiff to prevent the valve 3 from being opened by fuel pressure on the diaphragm 5. In a modified construction, Fig. 2, the rod 9 does not positively connect the membranes as in Fig. 1, but acts through a lever 18 pivoted at 19. The spring 8 does not therefore force the valve to its seat, with consequent possibility of hammering, as in the construction shown in Fig. 1. Further, the valve 3, which is loaded by a light spring 16, tends to be closed by the pressure of fuel on the membrane 5. To avoid pulsations being transmitted to the membrane 7, a constricted orifice 23, or a series thereof, is inserted in the pipe 12. The unidirectional control between the membranes 7, 5 is produced in a modification, by means of a head on the valve spindle 9 engaging, with lost motion, a fork on the rod connected to diaphragm 7. In a further modification, Fig. 4 (not shown), the two membranes form opposite walls of one large chamber, and the space between the membranes is connected to a compressor which supercharges the engine. The Specification as open to inspection under Sect. 91 (3) (a) describes also a still further modification wherein the larger membrane is subjected to the pressure of the engine lubricating oil and carries a spindle which actuates the spindle 9 of the valve 3 with a certain amount of lost motion. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in paper cutting machines
IPC: B26D1/38
Filed: 1925-05-18
Abstract: 253,342. Lerner, F. May 18, 1925. Rotary-blade type.-In a paper cutting machine a straight-edged rotary knife inclined to its axis of revolution and constituting in any of its positions a generatrix of one system of generatrices of a hyperboloid of revolution co-operates with a stationary straight-edged knife, the edge of which constitutes one of the generatrices of the other set of generatrices of the same hyperboloid. The rotary knife 2, Fig. 6, is held on spring-urged arms 14 pivoted on pins 13 to blocks 16 spaced by washers 17 on a boss 12 on the knife shaft. The knife is adjusted as a whole round an axis in its plane perpendicular to the axis of the shaft by adjusting nuts 19 engaging bolts secured to the blade, and round an axis perpendicular to its plane by mounting the knife 2, arms 14, and blocks 16 in transverse slots in the boss. The stationary knife 5, Fig. 10, is adjustable on a plane parallel to the axis of the knife shaft to vary the angle between the edge and the axis by mounting the knife 5 on a support 21 secured on transverse slots in the cutter frame. The distance between the edges 6 of the blade and the axis is varied by securing the blade on bolt 27 passing through transverse slots on the cutter and arranging adjusting bolts 26 contacting with the back of the blade. The web is fed by feed and drawing off rolls and the rotary cutter is operated through a speed gear. Specification 251,579 is referred to.

Title: Improvements in and relating to copying subtractive colour photographic films
IPC: G03C7/26
Filed: 1957-04-23
Abstract: 865,186. Copying colour films. CIBA Ltd. April 23, 1957 [April 23, 1956], No. 12983/57. Drawings to Specification. Class 98(2) Colour separation records are formed from a subtractive colour photographic film and the images therein, or to avoid damage of the original film in repetition work the images of a further set of separation records prepared from the first set, are formed into grainless dyestuff images in relief or tanned colloid material, and a copy of the subtractive colour film is formed from the latter images using light of very small aperture. The procedure avoids the scatter effect in copying silver images and has advantage of sharpness of outlines in the final copy as result particularly, of the images being in relief. Many methods of making such dye-relief or dye-tanned images are described briefly. A protective layer having a flat outer surface and of a material having a refractive index different from that of the material of the relief or tanned image may be provided, but this is described only with reference to Figures (not shown). Example 1 describes production of the records from a colour film using a pyrodeveloper, tanning bleaching bath, and dyestuff treatment; and the successive printing of these records with a bulb 33 centimetres therefrom on to positive three-layer film. Example 2 indicates production of three black and white colour separation negatives from a subtractive colour film, copying of the blue separation on to a fine grain bromide film, and then details the production of a colour relief image from the latter by a modification of the dye destruction process, with repetition of this for the original red and green separations, and successive printings in the manner of Example 1 for a final copy.

Title: Improvements in or relating to erection devices for gyroscopes
IPC: G01C19/44
Filed: 1947-05-14
Abstract: 633,954. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. May 14, 1947, No. 13013. Convention date, May 16, 1946. [Class 97 (iii)] A gyrovertical having a stabilized rotorbearing frame is provided with an erection device of the kind in which a container 13, Fig. 5, is mounted for continuous rotation on the frame about a normally vertical axis and contains a mass or masses such as the free ball bearings 14, 15, 16, &c. which when the container tilts with tilt of the frame are carried in a peripheral zone of the container from the low side to the high side, whereby an effective gravity force acting at the average centre of gravity P<SP>1</SP>, Fig. 6, of the mass or masses serves to apply an erecting torque to the gyro to erect the frame. The container is characterized in that the mass-supporting surface is parabolic, 18, Fig. 4, or spherical, 17<SP>1</SP>, Fig. 4, so that when the axis of the container is vertical, the tendency of the mass or masses to move towards the periphery under the action of centrifugal forces due to the rotation of the container is substantially balanced by the tendency of the mass or masses to move inwards due to the inclination of the surface. The container is driven from the rotor at a reduced constant speed by gearing 17 so arranged that the container is driven about a normally vertical axis although the rotor spin axis may be forwardly inclined as in Specification 619,939. During a tilt, the balls roll towards the lower periphery where they are retained by pins 21, 22, 23 and transported to the upper edge from whence they roll to the lower periphery. The gravity torque of the balls acting through the centre of gravity P<SP>1</SP> has one component in quadrature to the tilt which serves to erect the gyro and during a turn this component precesses the gyro spinaxis, due to its forward tilt, at the correct rate to maintain its direction relative to the changing direction of travel of the craft whereby the indications of the gyro-vertical are substantially unaffected by the turn, and the other component can, by suitable construction and design, be made to compensate for the effect of the centrifugal accelerations during the turn on the pendulosity of the instrument for a prescribed rate-of-turn. The gyro may be such that, if the mass or masses were removed, it would be in substantially neutral equilibrium.

Abstract: 709,997. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Ltd., and LEE, R. W. SEYMOUR-. Aug. 29, 1952 [June 1, 1951], No. 13069/51. Class 97(3) In order to produce precession of the gyroscope about an axis at a rate proportional to a primary control voltage irrespective of changes in rotor speed; a torque is applied to it that is proportional to the primary control voltage and to a voltage that is a measure of the rotor speed. The gyroscopic apparatus shown has a rotor-bearing frame 1 pivoted about the orthogonal axes 2-2, 3-3 in a support 10 by a gimbol 4, the rotor spinning about axis X-Y in frame 1. An electrical tacho-generator 6 on the frame 1 is driven by the rotor and the output voltage therefrom is fed to an amplifier 7 and thence to an electrical multiplier 8. Also supplied to the latter is a control voltage from a device 9. The output from the multiplier 8 is fed to a torque motor 5 so that the torque applied thereby is proportional to the speed of the rotor and also to the control voltage from devices 9 and the precession rate produced for a given control voltage is independent of the rotor speed. The control voltage and the output voltage of the tacho-generator 6 may be converted into mechanical movements which are multiplied together by a linkage to produce a resultant movement, this movement being applied to a potentiometer to produce a direct current signal which is applied to the torque motor 5.

Title: Improvements in the continuous production of phthalodinitriles
Inventor: KROEPER HUGO
IPC: C07C255/51
Filed: 1958-04-25
Abstract: The invention comprises a process for the continuous production of a phthalodinitrile, wherein a solid phthalic acid is fluidized by means of an inert gas current, with a dehydration catalyst, having a grain size of 0.1-1.0 mm. diameter, and the resultant fluidizable mixture is then conveyed by means of ammonia into a reaction zone, in which it is reacted at 250-500 DEG  C. in a fluidized layer.  Any of the isomeric phthalic acids may be used as starting materials.  Examples of catalysts which may be used are aluminium oxide, boron phosphate, aluminium phosphate, silica gel, molybdic acid, titanium dioxide, mixtures thereof, or a silica gel impregnated with phosphoric acid. The ratio of the initial material to the catalyst is preferably 1 : 20 to 1 : 3. This mixture is fluidized by means of an inert gas stream in a preliminary vessel.  Air or nitrogen may be used as the inert gas. The mixing vessel is preferably kept between room temperature and the melting-point of the initial material, e.g. 50-150 DEG  C., and the fluidization may be carried out at normal or increased, e.g. 1-2 atmospheres, pressure.  The fluidizable and flowable mixture obtained is then conveyed by a stream of ammonia into the actual reaction zone in such a way that the amount of catalyst in the reaction zone remains constant.  The mol. ratio of initial material to ammonia during the reaction in the fluidized layer may be 1 : 3 to 1 : 20.  Ammonia may also be additionally introduced directly into the fluidized layer.  It is preferable to withdraw a part of the catalyst continuously from the reaction chamber and return it into the mixing vessel, where the substance to be reacted is mixed therewith by fluidization with an inert gas stream.  A circulatory system for the unreacted ammonia is also preferably present.  The end products are obtained, for example, by cooling from the gases leaving the reaction chamber.  Examples are given of the preparation of terephthalonitrile and isophthalonitrile.

Patent GB-799907-A (GB)
Title: Method of alkylating organo-polysiloxanes
IPC: C07F7/08
Filed: 1956-04-30
Abstract: Siloxanes of the formul  (RSiO1.5)x, (R2SiO)x and (R3SiO0.5)2 or mixtures or copolymers thereof, wherein R is a monovalent hydrocarbon radical and x is an integer greater than 2, are alkylated by reacting them at 100 DEG  to 250 DEG  C. with aluminium compounds containing at least one aluminium bonded alkyl radical, e.g. aluminium trialkyls, etherates, alkylhalogenides and alkyl-alcoholates.  The reaction may be effected at normal or super atmospheric pressures and in the presence of absence of solvents or catalysts such as boron, zinc or cadmium alkyls or zinc halogen alkyls.  In the first stage of the reaction splitting of the siloxane bond occurs with simultaneous transfer of alkyl radicals from A1 to Si to give a siloxane more highly alkylated but of a lower degree of polymerization, and which in the second stage by reaction with further (a) siloxane yields an aluminium-silico-alcoholate, which may be hydrolysed, purified and fractionated to give a siloxane containing at least twice the number of Si atoms per mol; or (b) aluminium alkyl to give a siloxane of still lower degree of polymerization.  In examples, aluminium triethyl is reacted in the above manner with (1) dimethyl polysiloxane, (2) a mixture of dimethyl siloxane cyclic trimer and tetramer, (3) methylsiloxane (RSiO1.5), and (4) a dimethylsiloxane elastic gel.
