Title: Engine brake for internal combustion engines, in particular such of powered vehicles
IPC: F01L13/00
Filed: 1957-03-04
Abstract: 822,078. Engine braking. HALLER, R. March 4, 1957 [March 2, 1956], No. 7171/57. Class 7(6) A brake valve which, during engine braking, opens at a predetermined cylinder pressure to permit the escape of the compressed charge comprises a valve 10 connected to a spring-loaded piston 8 with a larger working face exposed to the pressure of the escaping gas than that of the valve 10, which piston holds the valve 10 open until the pressure in the cylinder has dropped to a value below that necessary to force valve 10 off its seat 4. During normal running a remotely operated eccentric 19 forces a spring abutment 16 down to increase the load of spring 17 so that the. valve 10 remains closed. For braking the abutment 16 is released so that valve 10 opens at a predetermined compression pressure, the pressure of the escaping gas immediately forcing piston 8 upwards to open escape ports 7 and holding it raised so that valve 10 recloses at a lower pressure than its opening pressure. In a modification the piston 8 is replaced by a membrane loaded by springs or fluid pressure.

Title: Angular propagation lenses and reflectors
Inventor: HORST ROBERT LEE
IPC: H01Q15/08
Filed: 1969-02-11
Abstract: 1,262,356. Aerials. ARMSTRONG CORK CO. 11 Feb., 1969, No. 7245/69. Heading H4A. An angular propagation lens structure comprises a plurality of substantially cylindrical dielectric lenses of equal diameter stacked one upon the other, each of said lenses exhibiting a dielectric gradation in radial directions, said gradation varying from lens to lens of the stack, with consequent variations of electrical lengths to incident energy passing through said lenses in directions generally parallel to their interfaces. As described, a radio lens structure comprises a plurality of dielectric lens discs 10, Fig. 1, which are stacked one upon the other with conductive interfaces 11 between them, such as metallic foil or paint, to form a cylindrical whole. In each disc 10 there is a gradation of dielectric constant from its centre to its periphery. A natural or artificial dielectric material may be used for the discs, for example, a low-loss polystyrene foam matrix supporting needle-shaped aluminium slivers in varying concentrations. The dielectric constant (K) of the uppermost disc may vary in accordance with the Luneberg law K=2 - (r/R)<SP>2</SP> (where r = radius at the point considered and R = outside radius of the disc) but the variations of dielectric constants in other discs are modified from the said law so that for waves passing through the discs phase delays are experienced which increase regularly from the lowermost to the uppermost disc. If a line source illuminates the lens structure at the left, a plane wave is produced at the right which is tilted upwards from the horizontal. A curved reflector may be provided over part of the cylindrical lens structure so that an incident radio beam is reflected back with an upward tilt, and an omnidirectional effect may be provided by three vertically disposed reflectors 21, 22, 23, Fig. 3, which are angularly spaced by 120 degrees (or a helical reflecting band may be disposed around the lens structure). Reference is made to Specification 1,041,411.

Title: An improved method of carrying out catalytic reactions, chiefly designed for use in the treatment of hydrocarbon oils
IPC: B01J38/12
Filed: 1940-04-25
Abstract: 538,697. Cracking oils ; catalysts. STANDARD OIL DEVELOPMENT CO. April 25, 1940, No. 7449. Convention date, June 3, 1939. [Classes 1 (i) and 32] In the regeneration of catalysts contaminated with carbonaceous deposits, e.g. catalysts used in the conversion of hydrocarbon oils, by circulating therethrough oxygenating gases, e.g. air mixed with diluent gases such as those obtained in the cracking process, the supply of oxygencontaining gases is discontinued during the final stage of the regeneration and the regeneration completed in the presence of the products of the regeneration containing oxygen with or without continuation of the circulation of the diluent cracking gases alone. The final content of oxygen in the regenerating gases is thus reduced to about 2 per cent. and it is unnecessary to purge the catalyst chamber before bringing it on stream again. Catalytic reaction chambers 10, 11 adapted to be alternately on regeneration and reaction cycles are supplied through manifold 12 and branch lines 13, 14 with the pre-heated vaporized oil and the cracked products are withdrawn through lines 15, 16. Regenerating medium comprising diluted air is passed through line 18, 19, 20 and the products of regeneration are withdrawn through lines 21, 22, 23 and in part, after cooling in heat exchanger 25, are recycled to mix with and dilute the air fed through line 27. At the end of the regeneration period the valve in the air line 27 is closed and the recycled regeneration products are alone passed through the regeneration chamber.

Filed: 1937-03-15
Abstract: 492,269. Clockwork - actuated valves. PHILIP, J. March 15, 1937, Nos. 7471, 8937, and 13989. [Class 135] [Also in Group XXXVII] A clockwork device for actuating valves comprises a main spindle 3 rotation of which by a setting knob 29 serves to wind the clock spring 7, start the mechanism through a clutch 6, and rotate concentric hour and minute discs 12, 9 through a set amount according to the rotation of the knob 29. The discs 9, 12 have peripheral notches 13, which, in the zero position, Fig. 2, are engaged by parts 15 pivoted on a lever 14 pivoted at 21 and biassed anticlockwise by a spring 32. Setting of the mechanism causes disengagement of the pawls 15 to tilt lever 14 clockwise. The pawls 15 ride on the peripheries of the discs 9, 12 until the clockwork returns the discs to zero when re-engagement of the pawl in the notches 13 allows lever 14 to snap downwards into its initial position. For controlling a valve, a lever 30 loosely mounted on spindle 3 and independent of knob 29 is provided and can be rotated through 90‹ to operate the valve through pins 31. Lever 30 is held in this position against the action of a return spring 24 by a latch (not shown) which is moved to its operative position by a pin 18 on lever 14 engaging a member 19 connected to the latch. When lever 14 returns to its zero position, Fig. 2, the latch is disengaged and the valve returns to its original position.

Title: Improvements in and connected with the Employment of Pulverised Fuel in the Furnaces of Steam Generators.
Inventor: ROBINSON JOHN GEORGE
IPC: F23K3/00
Filed: 1916-05-26
Abstract: 109,063. Robinson, J. G. May 26, 1916. Pulverulent-fuel furnaces; fuel, feeding; baffles.-A locomotive or other steam-generator is fired by pulverulent fuel by means of an air-current feeder operated at first by an auxiliary motor, such as an internal-combustion engine, and afterwards by the steam from the boiler; means for regulating the supplies of fuel and air are fitted. The fuel is taken from a ventilated hopper 1, Fig. 2, by two screw feeders 5 and is blown into tubes 12 by annular blasts from the pipes 11 and blower 9. The tube 12 conducts it to a nozzle 13, Fig. 1, and air inlet 16 controlled by a valve 17, and the mixed fuel and air pass closable ignition apertures 23 and enter the fire-box beneath a perforated crown or arch 30, additional air being supplied by apertures 27, above and below the arch, in the lining of the furnace. This additional air is induced by the draught, or may be injected by a steam nozzle. The blower 9 and conveyers 5 are normally driven by a steam turbine; at starting, they are driven by an internal-combustion engine 39. The turbine and the engine 39 are connected to the shaft of the fan 9 by clutches. which are connected by bell-cranks and links arranged so that one or both may be connected to the fan shaft. The supplies of fuel and air are regulated by varying the speed of rotation of the screw 5 and by means of a valve 10 in the air-pipe 11. These are affected simultaneously by operating a handle 58, which moves the valve 10 by means of the spindle of the bellcrank 52, and also, by means of the bell-crank 62, alters the stroke of a variable-stroke pump 54. This drives an hydraulic motor 53 which rotates the worm 6 and the worm-wheel 56. This hand-gearing may be replaced by a spring-pressed piston which is moved automatically by variations in the steam pressure or in the pressure in the smoke-box.
