Abstract: 1,269,014. Centrifugal casting processes. PLEUCO-G.m.b.H. CARL PLEUS & SOHNE AND DAIMLER-BENZ A.G. 20 Feb., 1970 [21 Feb., 1969], No. 8402/70. Heading B3F. [Also in Division C7] In a process for centrifugally casting hollow cylindrical bodies, e.g. cylinder liners, from a eutectic or hypereutectic cast iron melt having a total carbon content of at least 3À7%, the melt is superheated after the addition of alloying elements required for the formation of a pearlitic structure to provide a solution supersaturated with carbon and thereafter causing graphite to separate out either by inoculation of and/or reduction of the temperature of, the solution to form a heterogeneous mixture of graphite and liquid iron which is cast so that the hollow body produced has at its bore surface at least 3% of graphite in a pure pearlitic structure. The said inoculation or reduction in temperature may take place in the ladle or in the mould. The hollow bodies produced may contain several zones of variable structure or there may be a continuous graphite enrichment towards the bore. Peripheral speeds below 5 metres per second yield coarse graphite whereas speeds above this yield fine to punctiform graphite of dendritic formation.

Abstract: 568,542. Fuzes for aerial bombs, flares, &c. HEBARD, H. C., and IMBER RESEARCH, Ltd. May 31, 1943, No. 8667. [Class 9 (i)] A fuze which will prevent explosion or ignition of an aerial bomb, flare or the like if it is dropped inadvertently from a low height, as for example a bomb which failed to drop through freezing of the release gear and becomes released as the plane descends to land, comprises a wind-vane driven electric generator f which supplies current to a primer h and ignites a delay fuze j in a tube k ; this ignites a pellet l of propellant explosive and thereby moves a plunger to the left until a recessed part m thereof comes opposite a pin o on a resilient switch-arm p ; the switch then closes a circuit t, r, s through a primer rand initiates ignition of the main fuze u of the bomb &c. In the event of inadvertent dropping from a low altitude, the bomb or the like strikes the ground before the delay fuze k has ignited the pellet l, and as the wind-vane e then ceases to drive the generator f, no current is supplied to the circuit t, r, s and the primer is not ignited.

Title: Improvements in or relating to the Manufacture of Hollow Glass Articles.
IPC: C03B9/22
Filed: 1917-06-18
Abstract: 112,258. Westlake European Machine Co., (Assignees of Kadow, A.). Dec. 28, 1916, [Convention date]. Blowing.-In a machine for making electriclamp bulbs &c. and of the type described in Specification 26222/11, in which sets of glass-forming apparatus are carried by an horizontally rotating support and the blowing-spindles after receiving the gathers are turned over to complete the blowing, the blank hanging downwardly from the spindle is elongated by imparting to it a series of reciprocating movements in the direction of its length. Each hollow blowing-spindle 11, Fig. 2, receives a solid blank from the gathering-ram while in the vertical position with the blank-holding means 12 upwards. The blank is blown into hollow form while the spindle is rotated through pinions 28, 27 and bevel-wheels 25, 24 from a shaft 21 rotated through a worm gear and rack from a stationary cam as the support rotates. The spindle is then inverted to the position shown by a gear wheel 34 meshing with a gear wheel 35 keyed to a sleeve 36 forming part of the spindle support 23, the wheel 34 being rotated through a spiral pinion and a rack actuated by a stationary cam. The spindle is then reciprocated longitudinally to elongate the blank 55 by a bell-crank lever 45 having a forked arm 46 with rollers 48 engaging a grooved collar 49 on the spindle and adapted to bear against a stop-nut 50. The other arm 51 of the bell-crank lever 45 is in the form of a fork having rollers 52 engaging recesses 53 in a sleeve 43, which is reciprocated on the shaft 21 by a disk 40, Fig. 4, provided with a roller 39 engaging a stationary cam-way 38 having a series of bends 54 for this purpose. Bends 57, 58 on the cam-way 38 act respectively to raise the spindle 11 when it receives the blank from the gathering- ram and to lower it when it is enclosed by the finishing-mould. The reciprocation of the spindie may be accompanied by the controlled admission of compressed air.

Title: Improvements in or relating to the heating of gases
Filed: 1940-05-16
Abstract: 553,333. Fluid-pressure servomotor-control systems ; turbines. SULZER FRERES SOC. ANON. May 16, 1940, No. 8780. Convention date, July 7, 1939. [Class 135]. [Also in Group XXVI] An apparatus for transmitting heat from gases of combustion to another gas has the quantity of fuel supplied to the chamber in which combustion takes place regulated in accordance with the pressure in that chamber so that the quantity is increased as the pressure rises. In the form shown in Fig. 2 the fuel regulator 24 for the burner of the heat exchanger 27 is actuated by three power devices 33, 46, 51 coupled to the regulator by a bell-crank lever 39, floating levers 37, 38 and links 35, 36, and each provided with a control valve 33<SP>1</SP>, 46<SP>1</SP>, or 51<SP>1</SP> fitted with floating lever follow-up devices. The valve 33<SP>1</SP> is actuated by a bellows 32 subject to the pressure in the combustion space 30, the valve 46<SP>1</SP> by a diaphragm 45 subject to the pressures in the inlet and outlet pipes to and from the heating coil and the valve 51<SP>1</SP> by a bellows 50 connected to a thermal feeler 49 in the outlet pipe 28. An increase of pressure in the combustion chamber or an increased flow through the heater increases the full supply while an increase of temperature in the pipe 28 reduces the fuel supply. To keep down the temperature of the gases of combustion part of them is returned by a blower 22 to the air inlet pipe 20. The motor driving this blower is controlled by a regulator 25 coupled by a crank arm 41 and link 40 to the bell-crank lever 39 and independently by a servomotor 53 controlled by a slow-acting expanding- rod thermostat 54 in the pipe 28. The invention is particularly adapted for use in the air turbine plant shown in Fig. 1. A compressor 1 fitted with an intermediate cooler 2 delivers air through a preheater 3 to a heat exchanger 4 from which it passes to a turbine 5 driving the compressor 1.  The exhaust from the turbine 5 passes through a heat exchanger 6 to a second turbine 7 driving a generator 16. The exhaust from the turbine 7 divides into two parts, one passing through the preheater 3 and cooler 9 to the intake of the compressor 1 the other passing to the combustion chambers of the heat exchangers. The products of combustion pass through the preheater 3 to an auxiliary turbine 12 which assisted by a motor 15 drives a compressor 13 delivering make-up air through a cooler 14 to the compressor 1.

Class 57 [Also in Group XXVII] A centrifugal governor a is connected to a fuel pump control bar c by a lever d pivoted on a manually operable lever e and provided with projections h arranged to come succesively into engagement with corresponding steps j as the engine speed rises, the stop being provided on one end of a lever i which may be moved to an inoperative position by a manually-operable push piece k so that the lever d can be moved to a position in whch the pump provides extra fuel for starting. The lever e is connected by a pair of blade springs g to a lever f which is moved downwardly from the position shown to bring the upper projection h into contact with the upper stop j and move the bar c to increase the fuel supply. Further movement of the lever f deflects the upper blade spring g so that as the engine speed increases the lever d is moved-in the same direction to effect a further increase in fuel until the spring g returns to its normal position. Further increase of speed causes the lever d to move in the opposite direction and reduce the fuel supply. If the lever f is moved still further, the above action is repeated with the lower projections h and stops j. The push piece k preferably acts through a catch piece m loaded by a spring n. On depressing the push piece a grooved part of the catch piece engages and is held by the edge of a hole p and thus holds the lever i in a downwardly deflected position against the action of a spring q until the lever d strikes the catch piece and thus allows it to be returned to its initial position. A manually-operable lever r adapted to en. gage a shoulder s on the bar c is used to bring the engine to rest.
