IPC: B21C23/01
Filed: 1956-12-04
Abstract: 853,188. Making turbine blades; extruding; destructible cores. WIGGIN & CO. Ltd., H. Nov. 27, 1957 [Dec. 4, 1956], No. 37050/56. Classes 83 (2) and 83 (4). An extrusion billet has one or more blind holes filled with a removable material which flows during extrusion and at the inner end of each hole there is provided a small plug of a material of different density to the billet metal. In the extrusion of turbine blades the billet is of a creep-resisting nickel-chromium or nickel-chromium-cobalt base alloy, the filler is of an ironmanganese-titanium alloy and the plug is of molybdenum or a molybdenum-titanium alloy. The billet is first extruded through a die of aerofoil profile and the solid end is then upset to form the root; alternatively the root may comprise a non-extruded part of the billet. After extrusion, and before or after upsetting, the workpiece is examined radiographically whereby the denser material of the plugs shows the inner ends of the holes and enables further holes to be drilled through the root to intersect the filled holes. The leading end of the aerofoil part may be subsequently upset to form a shroud.

Title: Improvements in or relating to apparatus for feeding gas and air to hot blast stoves
IPC: F23N1/02
Filed: 1958-11-20
Abstract: 910,886. Controlling gas burners. ZIMMERMANN & JANSEN G.m.b.H. Nov. 20, 1958 [Nov. 20, 1957], No. 37438/58. Class 75 (1). A control apparatus for a hot blast stove comprises a gas regulating member GRBV and a gas safety valve GSBV in the gas supply pipe GM of the burner and a switch SBVPS which closes when the pressure in the air pipe AM supplying the burner drops below a predetermined value to de-energize the motor ELDRO of the gas safety valve GSBV so that the valve closes, the arrangement being such that the gas regulating valve GRBV must be first closed and then opened before the motor ELDRO can be re-energized to open the gas safety valve GSBV. In normal operation the contactor ELDRO energizing the motor ELDRO is closed by an electromagnet having terminals 1, 11 included in a circuit from a mains line R back to a mains line O through a switch SBVCS closed when the gas regulating member GSBV is open, a switch WTC closed when the temperature of the combustion chamber is above the ignition temperature of the gas/air mixture and contacts 3, 13 of an auxiliary relay SBVAR. If the air pressure in the air pipe AM drops the switch SBVPS closes its contacts to energize the auxiliary relay SBVAR which therefore opens its contacts 3, 13 to de-energize the contactor ELDRO and stop the motor ELDRO, and closes contacts 2, 12 to keep the relay SBVAR energized. The gas regulating member GRBV is then closed manually or by a motor to open the switch SBVCS to de-energize auxiliary relay SBVAR to re-close contacts 3, 13 thereof. When the gas regulating member GRBV is again opened the switch SBVCS closes and the motor ELDRO operates to open the safety valve GSVB. The system also includes a timing relay SBVTR which opens its contacts 2, 12 after a predetermined time to de-energize the motor ELDRO. If, however, an air regulating member ARBV in the air pipe opens within the predetermined time a switch SBVIS closes and shunts the contacts 2, 12 of the timing relay SBVTR, making the latter ineffective to stop the motor ELDRO.

Abstract: 1284480 Measuring projectile velocity WERKZEUGMASCHINENFABRIK OERLIKON-BUHRLE AG 4 Aug 1970 [12 Aug 1969] 37502/70 Heading G4H Apparatus for measuring the velocity of a projectile as it leaves the barrel (K), Fig. 1 (not shown), of a gun, comprises two rings L 1 , L 2 , of coiled wire through which a projectile (G) is in use, adapted to pass, the coils being spatially separated by rods (S) and electrically connected in series with a D.C. supply, a pulse being generated in each coil consecutively as the projectile passes through, and a thermistor R Th  in one of the rods S adapted to compensate for changes in the spatial distance between the rings owing to temperature change. Pulses induced in the coils L 1 , L 2  are passed through a transformer T, amplified at OP 1 , applied to a squaring circuit, preferably a Schmidt trigger JF, inverted and amplified at NV and applied to the input of a monostable MMF, an input pulse causing this circuit to attach its quasi-stable state for a time # which time depends upon the voltage input U k  from a potential divider containing the thermistor R Th , the output B from the monostable being applied to one input of an AND gate U 2 , the other input being supplied from the right-hand side G 2  of a flip-flop FF preset so that the output voltage of the righthand side G 2  is of the same sign and magnitude as that of the circuit MMF in its stable state, thereby causing the gate U 2  to be opened at the end of the output pulse of the circuit MMF, i.e. after a time #, the voltage flank produced being fed to a second monostable MF via an OR gate O causing the circuit MF to attain its quasistable state for a particular period, the rising flank of this pulse opening a gate T admitting clock pulses from a quartz oscillator QG to a counter Z, the output pulse of MF also being fed to the symmetrical input of the flip-flop FF to change the state of the latter applying a voltage to the AND gate G 1  of the same magnitude and polarity as the input pulses at E. The gate G 1  is opened on receipt of a second pulse from the point E and the rising flank of the resulting pulse from MF closes the gate T and the falling flank resets the flip-flop FF to its former condition. Thus the time interval between pulses at the point A is shortened with respect to that between pulses at point E by the amount # dependent upon the temperature in the vicinity of the apparatus.

Title: Improvements in and relating to fuel injection devices for internal combustion engines
IPC: F02M59/00
Filed: 1928-12-31
Abstract: 327,183. Hemmingsen, T. V. Dec. 31, 1928. Actuating by liquid pressure; two pumps in series; regulating delivery by by-passes and by opening suction valves.-apparatus for supplying internal-combustion engines, with liquid fuel comprises a primary pump 3 drawing from a tank 1 and feeding through pipes 10, 11, 45 a number of feed pumps 25, one for each engine cylinder. The pump 3 has an adjustable relief valve 8 for regulating the pressure in the pipe 10, and adapted when open to permit part of the pump delivery to return to the tank 1. The pump 25 comprises a differential plunger 26, 27, of which the smaller end works in the pump chamber 30 supplied by the pipe 45, while the larger end works in a chamber 38 supplied with fuel by the pipe 11 through a valve 40 and pipe 39. The valve 40 is reciprocated by an eccentric 41 and is rotated by an eccentric 55 through a lever 52 and links 51, 49 engaging the square spindle 47 of the valve. The valve has a peripheral recess 46 which, during the descent of the valve, opens the pipe 11 to the pipe 39 and admits pressure fuel to the chamber 38 to effect the delivery stroke of the plunger 26, 27. During the rotation of the valve a vertical edge of the recess 46 cuts off the pipe 11 and at the same time connects the pipe 39 to a release pipe 44, thereby stopping the delivery of the pump 25 to the engine valve 35. The moment of stopping the delivery and the stroke of the pump may be varied by hand or governor adjustment of an eccentric on which the lever 52 rocks, thus varying the moment of closing the pipe 11 by the vertical edge of the recess 46. In the form shown in Fig. 6, the supply from the pump 3 to the chambers 30, 38 of the pump 25 is controlled by a piston valve 40 which is operated on the downstroke by the engine pressure through a pipe 57, and during this stroke closes the release pipe 44 and the pipe 11<b> supplying the chamber 30, and opens the connection between the pipe 11<a> and the pipe 39 supplying the chamber 38. Delivery by the plunger 27 is stopped when a by-pass pipe 31 controlled by an inclined edge 27a on the plunger opens the end 31a of the pipe. The moment of opening may be varied by turning the plunger by means of an arm 61 connected to the governor &c. In another form, separate slide valves control the admission to the chambers 30, 38, that controlling the admission to the chamber 30 having an inclined edge controlling the supply pipe 11, so that, by angular adjustment of the valve, the amount of fuel admitted to the chamber 30 during the suction stroke of the plunger 27 may be varied.
