Title: Improvements in or relating to the cooling of internal-combustion engines
IPC: F01P7/02
Filed: 1941-09-22
Abstract: 552,164. Cooling cylinders, charge, oil &c. READ, J. R., and GREATRIX, F. B. Sept. 22, 1941, No. 12262. [Class 7 (ii)] [Also in Groups XXXIII and XXXIV] In an air-cooled aircraft or other engine having one or more banks of cylinders extending lengthwise of the crankshaft, an air-cooled cooling device, for example for oil or charging air, is mounted at one or each end of the bank of cylinders with its cooling-air passages normal to the length of the bank, and a flow of air is directed transversely of the bank through the cooler and in parallel between the cylinders. The cooling device may cool oil for lubricating the engine or for operating mechanism in the aircraft, or may cool the air supply to the engine between or after the stages of a multi-stage supercharger. In one form, Figs. 1 and 2, the engine has four banks of cylinders 11 and a cooling device 26 of substantially the same dimensions as a cylinder is arranged at the rear end or at each end of each bank. The engine is enclosed in a nacelle 12 and baffles 15 along each bank of cylinders divide the space around the engine into upper and lower passages 16 and side passages 17 closed at the ends by bulkheads 14, 21. Air entering through passages 23 in the wing 13 flows over a supercharger 19 in the compartment 18, through the passages 16, cooling devices 26 and passages 17 to outlets 24 controlled by adjustable flaps 25. The air also passes between the cylinders from the passages 16 to the passages 17. Exhaust manifolds 27 are arranged in the passages 17 and discharge through the outlets 24. In a modification, the air is admitted through the nose of the nacelle and through the lower passage 16 and compartment 18 to the upper passage 16 ; from both passages 16 it flows to the passages 17 through the coolers and between the cylinders. In another form, Fig. 4, an inverted V-engine has a single air-entry passage 16 from which the air flows through the coolers 26 and between the cylinders to an outlet space 17.

Filed: 1929-04-20
Abstract: 327,590. Ashworth, W. E., and Linney, J. E. April 20, 1929. Diaphragms. - A conical diaphragm for loudspeakers or gramophones is formed from hatmakers twill or muslin which is steeped in a solution of or otherwise impregnated with shellac and allowed to dry. The saturated fabric is stretched over a conical block of wood or metal covered with felt and is shaped to the contour of the block by the application of a heated iron or by a heated press. After shaping, the cone is further coated with shellac solution, thoroughly dried and again well ironed to the shape of the conical block to give it pliability and the necessary smooth facing. The base of the cone may be strengthened by a strip of fabric held in position by the shellac and incorporated either before or after the preliminary steeping of the fabric. Instead of or in addition to the strengthening strip, a flange may be formed around the base of the cone during the blocking thereof and this flange may be used to attach the cone to the supporting strip of fabric.

Title: Improvements relating to predicting devices
Inventor: ROSTON BENJAMIN
IPC: F42C13/02
Filed: 1957-04-16
Abstract: 1298931 Proximity fuzes EMI Ltd 9 April 1958 [16 April 1957] 12481/57 Heading F3A The fuze of a missile is fired by a predicting device responsive to the position of the target relative to the missile. The instant of fuze operation is determined from target position information received continuously during the final period of missile approach to the target. The position information consists of signals representing the rate of rotation of the sight line between the target and missile and is determined by an infra-red detector sensitive to the radiation from a jet plume. The succesive instant at which the line of sight rotation has the values ¢, 1, 2 radians per second are recorded and the time to reach the point of nearest approach is computed from them by means of an equation of specified form. The rate of sight line movement in space is measured by gyroscopes mounted on the infra-red detector, the outputs from which are added and applied simultaneously to three thyratrons which conduct successively when the rate of rotation of the infra-red detector reaches the three predetermined values. Each thyratron, when commencing to conduct, inititates the operation of an integrating circuit corresponding to a term of the specified equation, the outputs from which are applied to summing and comparator circuits which produce a signal to operate the fuze at the appropriate instant. The missile warhead may be of the blast type or may be ejected laterally towards the target. In the latter type a correction is necessary to allow for the separation of target and missile for low speed ejection and for the time between the instant of nearest approach and the instant at which the sight line coincides with the direction of ejection for high speed ejection.

[Also in Group XXXVI] A ferro-electric data storage device comprises a plate of ferro-electric material, coated on one side with a material having a non-linear impedance characteristic, between two electrodes. The preferred form of the invention is as an array of data storage elements, as shown in Fig. 3, where 1 is a plate of ferro-electric material 1 cm. square and 0.01 cm. thick, 3 is the non- linear impedance material, and 200 to 249 and 400 to 449 the electrodes, one data storage element being formed at each intersection of an electrode of the series 200 to 249 with an electrode of the series 400 to 449. The ferro-electric material may be barium titanate, preferably a slice from a single crystal. The " non-linear impedance " material being, e.g., cadmium sulphide activated with gallium settled on the face of the element from a solution of benzene or amyl acetate containing ethyl cellulose as a binder or dusted on to the surface after the surface has been wetted with a suitable binder. Alternatively the layer may be of a powdered semi-conductor, e.g. silicon carbide, in a binder. The electrodes are preferably of gold evaporated on to the surface through a suitable mask. The ferro-electric plate may be coated on both sides with the non-linear impedance material and additional electrodes may be placed between the ferro-electric plate and the non-linear impedance material. The addition of the non- linear impedance material is said to increase the ratio of the value of the voltage pulse that will just not change the state of polarization of the dielectric to that value that just will.

Class 38 (iii) [Also in Group XXXVIII] A control system for a constant field D.C. motor, which is intended to run at a speed proportional to the applied voltage, comprises a bridge one arm of which contains the motor armature 11. A moving coil or equivalent current-responsive device has a centre-tapped winding 15 constituting second and third arms of the bridge, the fourth arm of which is comprised by resistor 13. The current-responsive device has a moving arm 16 which co-operates with potentiometer resistor 17. A battery is connected across the resistor 17, the supply-points of the bridge being indicated at S<SP>1</SP>, S<SP>2</SP>. For use, the bridge is adjusted to balance with the motor armature held against rotation. In operation, the potentiometer 17, and so the supply voltage between S' and S<SP>2</SP>, is adjusted automatically in accordance with the unbalance current in the winding 15, so that, in the absence of any additional influence tending to actuate the voltage adjusting means, the supply voltage tends to become and remain at zero. For applying an additional influence tending to actuate the voltage adjusting means and increase the supply voltage the device 15, 16 may have its moving assembly unbalanced mechanically so as to respond to acceleration as well as unbalance current, the number of revolutions of the motor in a given time corresponding to the integral of the acceleration. The moving assembly may be balanced mechanically, the motor speed being dependent upon the magnitude of a force applied to the assembly by means of an additional winding. In a modification, Fig. 2 (not shown) a centre-tap of the resistor 17 is connected to point S<SP>1</SP>, the motor being so adapted for reversal.

Title: Improvements in and relating to rubber-containing compositions
Inventor: KROMOLICKI ZYGMUNT
IPC: C08F279/06
Filed: 1959-04-15
Abstract: Mouldable rubber-containing compositions are obtained by polymerizing a mixture of a styrene and methyl methacrylate in the presence of a diene synthetic rubber which constitutes at least 5% by weight of the final product, and subjecting the product so obtained to a hot rolling or mastication treatment.  Rubbers specified are butadiene-styrene copolymers and polychloroprene. Styrenes specified are styrene itself, alpha-methyl styrene, vinyl toluene and chlorostyrenes.  The polymerization may be carried out with the rubber in solution in the monomer mixture, in solution in a common solvent with the monomer mixture, or in dispersion.  In the example a butadiene-styrene rubber is dissolved in a mixture of styrene and methyl methacrylate and subjected to prepolymerization until the mixture contains 30% polymer, the resulting dope, with the admixture of lauroyl and benzoyl peroxides, is dispersed in water with the aid of polyvinyl alcohol and the polymerization is completed.  The resulting product is milled at a temperature of 160 DEG C. Specification 893,084 is referred to.
