Title: Improvements in or relating to internal combustion engines employing liquid fuel injection and compression ignition
IPC: F02B19/08
Filed: 1936-02-13
Abstract: 470,404. Oil engines. RICARDO, H. R. Feb. 13, 1936, No. 4367. [Class 7 (iii)] The spherical combustion chamber of a compression ignition engine communicates with the cylinder through similar parallel or slightly inclined cylindrical passages F, in a hot plug C. The axis of the fuel injector D lies in a particular plane and at a certain perpendicular distance from the centre X of the combustion chamber, the axis of the fuel jet meeting the wall of the combustion chamber at a point situated near the orifices of the passages in the plug. The passages are preferably arranged so that the air streams through them blend into a common stream before reaching the injector. The direction of the fuel jet may be such that the main portion of the fuel is carried by the rotating air agains t the hot plug. The combustion chamber may be arranged in the cylinder head or at the side of the cylinder and it may be offset from a radial plane containing the cylinder axis. The invention is applicable to engines in which the whole or only part of the combustion space is formed by the spherical chamber. For starting purposes, the combustion chamber is provided with a heating plug E. Specifications 371,025, 384,340, 431,345, and 439,426 are referred to.

Patent GB-414435-A (GB)
Title: Process for the production of lacquers containing artificial resins and of materials for making such lacquers
Filed: 1933-02-13
Abstract: In the production of lacquers containing artificial resins, particularly phenol-formaldehyde condensation products, soluble and heathardenable resins or soluble resins capable of being hardened in the presence of hardening agents are mixed with fillers and pigments, in the absence of solvents, under pressure and at a temperature sufficiently elevated to drive off volatile constituents and to render the resin plastic or liquid, but not high enough to convert the resin into its final condition.  The process may be carried out in a heated masticator, or with the aid of heated kneading rollers, or the finely powdered mixture may be passed through heated nozzles under pressure.  The powdered final product is then mixed with any suitable solvent, and, owing to the penetration of the resin into the grains of the filler or pigment, the resulting lacquer remains permanently homogeneous.

Patent GB-215470-A (GB)
Title: Improvements in or relating to the manufacture of ammonium compounds
IPC: C01C1/247
Filed: 1923-02-16
Abstract: A mixture of ammonium sulphite and sulphate is prepared by introducing ammonia and water vapour or ammonia, water vapour and water in a fine state of subdivision into a mixture of sulphur dioxide and air, the proportions being such that the temperature does not rise above 100 DEG  C. and that the product is obtained in a substantially dry condition.  Slight excess of water vapour beyond the quantity theoretically required is employed however in order to obtain the product in an active condition capable of rapid oxidation wholly to sulphate.  The mixture of sulphite and sulphate is exposed to air in heaps which are gently raked mechanically or by other means.  Part of the air may be introduced together with the ammonia and water vapour and the ammonia may be used in slight excess.  Most of the ammonium sulphite-sulphate mixture is precipitated on cooling the gaseous reaction mixture to a temperature not exceeding 40 DEG C., but a further quantity is recovered by means of a Cottrell precipitator.  A filter consisting of ammonium sulphate supported on perforated trays may also be employed and the issuing gases are finally passed into a tower and scrubbed with water, ammonia being recovered from the resulting solution of ammonium salts.

Abstract: 433,311. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, EVEREST, F. J., 2, Brookside Close, Dunchurch Road, Rugby, and OLDHAM, T. J. F., Aldersey, Crick Road, Hillmorton, near Rugby. Feb. 13, 1934, No. 4770. [Class 38 (iii)] In a Ward Leonard system, the motor M is stopped by means of a condenser C adapted to discharge into the field F1 1 of the generator G momentarily to reverse its polarity. After coming to rest the motor armature may be prevented from reaccelerating by a mechanical brake, or alternatively, a switch or rectifier may prevent recharging of the condenser. The resistance of the condenser discharge circuit may be sufficiently high to render negligible the effect of recharging. With the motor exerting a load torque under stopping conditions, a compensating field winding F2 may be provided on the generator to correct for the voltage drop in the armature loop circuit, and the armature reaction. This compensating field may be supplied from an additional generator B excited by the motor armature current, a choke L being included in circuit with the field F2 to keep it constant over the stopping period, and to minimize its damping effect on the main generator field. The condenser C may be charged during normal running from the exciter Ex directly or through a potentiometer, and it may be charged in two parallel sections which are discharged in series.

Title: Improvements in and relating to knitting machines
IPC: D04B11/00
Filed: 1941-04-19
Abstract: 548,713. Knitting-machines. COTTON, Ltd., W., WILDERS, G., and LYNAM, J. E. April 19, 1941, No. 5077. [Class 74 (ii)] The speed regulating apparatus of a straight-bar or other knitting-machine comprises a speed controlling member 12 controlled manually to determine the normal working speed and automatic control means operating upon the member 12 to give at least two different speed reductions from the speed set by the manual control. The automatic control may effect speed reduction for one course, as for fashioning, speed reduction for a number of courses, as for plating, and reduction to a still lower speed for welt-turning or carrier-changing. Automatic stop mechanism operated by the machine pattern mechanism may also be provided. The automatic control means may be constructed as a unit. The speed control member 12 is in the form of a quadrant engaging a pinion 11 which rotates the commutator of a variable brush commutator motor 10; the pinion is spring-biased in a speed increasing direction so that an arm 13 of the quadrant is held up against an adjustable stop 25 upon a rod 15 forming part of the manual control. The rod 15 is secured to a lever operated by the usual power rod of the machine. The arrangement permits the quadrant being rotated in speed-reducing direction by the automatic control without interfering with the manual control. The quadrant 12 supports a sleeve 26 mounted upon a longer sleeve 27 in turn mounted upon a rod 28 of the automatic control; the sleeve 27 is arranged between an adjustable stop 29 on the rod 28 and a slidable collar 30 urged by a spring 33 against the end of the sleeve 27. The automatic control means, which operates by moving the rod 28, comprises a shaft 35 having left and right handed worms 36, 37 and a cam 39. Plungers 42, 43 are moved by pattern controlled means, e.g. from the timing chain, to engage the worms 36, 37, and a truck 51 is also pattern controlled so as to be movable into and out of the path of the cam 39. The cam 39 and truck 51 serve to reduce the machine speed for a single course as, e.g. in fashioning; the worms 36, 37 are used for very low speeds as, e.g. during welt turning, the arrangement permitting the decrease and increase in speed to be effected gradually throughout the whole of a single course. The plungers 42, 43 are mounted upon a sliding block 40 connected by a link 49 to a bell-crank lever 50 which bears against a lever 31 to which the rod 28 is secured. The truck 51 is slidably mounted upon the lever 31. Stop motion. A cam 38 is provided upon the shaft 35 and acts through a lever 58, rod 59, and lever 60 to operate a stop switch 81. The lever 58 is normally held away from the cam 38 by a catch 62 which is tripped at the appropriate time, e.g. at the completion of a stocking blank, by a lever 63 under pattern control.
