Title: Method and apparatus for making deep drawn metal shells
IPC: B21D22/24
Filed: 1973-06-08
Abstract: 1432704 Cupping D C GRIGORENKO 8 June 1973 27464/73 Heading B3Q A deep-drawn metal shell having a bottom wall and a side wall is made by drawing a flat workpiece in one direction to form a cup shaped blank, immediately redrawing it in the opposite direction to turn it inside out and form a shell longer and narrower than the blank and immediately ironing the shell to elongate it and further reduce its wall thickness. As shown, strip 76 is fed vertically downwardly between flanges 75 of a guide 70 and hydraulic fluid is supplied to a pair of rams (26), Fig. 6 (not shown) to allow springs 83 to draw a die plate 39 secured to piston rods 37 to the right, Fig. 8. A die 63 carried by the plate cooperates with a punch 65 to punch a circular workpiece from the strip. Scrap is stripped from the workpiece by the return of the guide 70 which is spring-mounted on a guide plate 68. Further advance of the piston rods 37 causes a drawing die 57, within the die 63, to force the workpiece over the end of a hollow mandrel 60 mounted over a fixed bolster plate 22 to form a cup. As the rams (26) reach the end of their stroke a ram (29), Fig. 6, is energized to advance a punch 54 into engagement with the centre of the cup base to turn the cup inside out and redraw it through the cavity 59 of the mandrel 60. Movement of the punch further to the right carries the blank through ironing dies 98-100. A hemi-spherical head 46 at the rear end of the punch engages in a complementary recess in a guide plate 43 mounted on the piston rod 30 of ram (29) to allow limited floating movement of the punch to ensure its coaxial alignment with the ironing dies. As the punch reaches its fully extended condition, the plate 43 trips a switch (not shown) which reverses the ram (29) and energizes a solenoid (118), Fig. 16, to cause notched portions 112 on stripper blocks 109 to engage the rear edge of the shell as the punch is withdrawn. The apparatus comprises fixed bolster plates (21), 23 through which pass four rods 25, one at each corner. Slidable on the rods between plates (21), 22 are a guide plate (36), the guide plate 43, the die plate 39, a plate 68 which guides the die 65 and work guide 70 and a plate 77 which is fixed to the die plate 39 by rods 79 and urged away from the plate 68 by springs 83. Movement of the plate 77 towards plates 22 and 68 respectively is limited by stops 88 and 87. Between bolster plates 22 and 23 the ironing dies are fixed to rods 25. When the ram (29) is almost fully retracted the plate 43 engages the plate (36) which retracts the piston rods of the rams (26) and thus the plates 39, 68 and 77. The final portion of the movement compresses the springs 83 in readiness for the next operating cycle. The work guide 70, punch 63 and die 65 may be replaced by a holding mechanism for pre-cut circular blanks.

Abstract: 732,893. Luminescent screen. PRINGLE, R. W., ROULSTON, K. I., and BROWNELL, G. M. Nov. 10, 1950 [Nov. 10, 1949; Jan. 12, 1950], No. 27528/50. Class 39 (1). [Also in Group XL (b)] intensity of gamma and neutron radiation is determined by detecting photo-electrically the scintillations of a single crystal receiving the radiation. Crystal and mounting.-Examples of crystals which scintillate when bombarded with gamma rays are napthaleno, anthracene, stilbene, chrysene, calcium or cadmium tungstate, or potassium or sodium iodide activated with thallium. As shown in Fig. 2, the crystal 1 is secured by a transparent cement upon the roughened end of a photo-multiplier tube 2. The crystal is in the form of a truncated cone and is covered bv a shield 11 of foil adhesively secured to the crystal this shield serving both to exclude moisture from the crystal and to reflect the scintillations into the tube. In a modification (Fig. 4, not shown), the crystal is situated near the cathode of an image dissector, the cathode emitting in response to the scintillations and the electrons being accelerated by a grid and allowed to impinge on a fluorescent screen the scintillations of which are detected by a conventional photo-cell. Circuit (Fig. 1).-The scintillations received at the cathode of the multiplier 2 or the image dissector referred to above produce current pulses in an inductance in the anode circuit of the multiplier. A damped oscillatory voltage of longer duration than the scintillations is developed across the inductance 221, this voltage being fed through a screened lead 19 to a cathode follower 15 and a pair of resistance capacity coupled valves 17, 17<SP>1</SP>. If the amplification of the multiplier is adequate these valves may be omitted. The output of the second valve is rectified by a germanium diode 5 and used to trigger a conventional flip-flop circuit comprising valves 23 and 24 the magnitude of the pulse which triggers the circuit being preset by varying the bias on the valve 23. A microammeter 26 is connected in the anode circuit of valve 23<SP>1</SP> and is shunted by a condenser C10 to smooth out statistical fluctuations. Resistance R19 in series with the meter permits variations of the averaging period of the instrument. In modifications a pulse dividing circuit with earphones might be used.

Title: Flow control apparatus suitable for use with liquid fuel nozzles
IPC: F02M69/00
Filed: 1955-09-27
Abstract: 797,552. Supplying liquid fuel to burners CHRYSLER CORPORATION. Sept. 27. 1955, No. 27530/55. Class 75(1) [Also in Groups XXVI and XXIX] Fluid flow control apparatus such as a fuel supply system for a gas turbine engine consists of a principal fuel pump 43 feeding fuel from a metering device 10 through a conduit 48 to spill nozzles 132 the return line 130 from which passes through'a cooler 128 and thence to ports 116 in a sleeve containing a slidable valve member 70 having ports 110 which coact with the ports 116, and ports 104 coacting with ports 102 in the sleeve which communicate through a passage 92 with a discharge conduit 84 from one or more secondary pumps 44. The interior of the valve member 70 communicates through a passage 80, 78 with the inlets to the pumps 43, 44. The conduits 84, 48 communicate with each other through a check valve 88 which is closed by pressure in the conduit 48 when the pump 43 is working normally. The valve member 70, due to its connection 78 with the inlets to the pumps and to a connection 124 with the inlet to the metering device 10, is movable in response to the pressure difference across the metering device. Thus, e.g. if the pressure drop across the metering device increases, the valve member 70 moves downwardly to increase the opening of the ports 110 and thereby reduce the amount of fuel discharged at the nozzles. During normal operation the pump 44 discharges back to the inlet through the open ports 104. Should the pump 43 fail the pressure on its upstream side will tend to increase thereby causing upward movement of the valve member 70 to close the ports 104 whereby the pump 44 is caused to discharge into the conduit 48 to supply the nozzles, the ports 110, 116 remaining partially open for controlling the return flow. The metering device 10 is fed with fuel by a booster pump 38 and a transfer pump 39 and includes a regulating valve 11 actuated by air and fuel diaphragms, and further valves 28, 30 actuated respectively by temperature responsive means and manually. A dumping valve 142 is positioned by an overspeed governor 144 driven by the turbine.

Each housing is generally cylindrical in form, includes three co-operating rolls 7, 8 and 9, and is held against surfaces 2 and 3 of its saddle by a spring- loaded block 19. The housings being so closely spaced, the driving shafts, and also the separate motors and gear-boxes, of each are staggered. Housing H 1  is driven by a shaft 11 from a gear-box 38 and motor output shaft 37, while the next housing H 2  has its drive shaft 33 at a higher level. Rolls 7 and 9 are driven by bevel gearing from roll 8. For removing or changing the roll housings a pivoted clamp C, common to all the housings, is rotated to the chain dotted position to release the block 19 from clamping engagement. The clamp is rotated by piston rods 30 acting through bell crank levers 27 and links 24. For each housing, a pivoted arm A, situated beneath the housing and in a slot in the saddle S, can be rotated clockwise by a piston rod 54 to shift the housing on to a waiting car R. The cars can be moved on rails 65 and 66 clear of the mill base and, if desired, further cars D carrying replacement housings can be moved on transverse rails 73 towards the mill. In an alternative form the pivoted arms A for shifting the housings may be mounted on the cars R themselves, and similarly on the cars D.

Abstract: 1,011,751. Steering vehicles. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. July 19, 1962, No. 27846/62. Heading B7H. [Also in Division F2] An hydraulic pressure control valve comprises a valve housing 1 with a chamber arranged for communication with a supply passage 8, a return passage 6, and a passage 10 requiring supply of hydraulic medium at a controlled pressure for application to an actuator 4, and a valve member 2 slidably mounted in the housing so as to control the degree of communication between the chamber and the return passage in dependance on the valve travel, the housing being provided with a control edge 21 and the valve member with two control edges 20, 23 formed by transition portions of a fraction of a millimetre adjacent a reduced diameter portion 9 of the valve member-that is to say in the example shown the diameter of the cylindrical portion 9 is smaller by a fraction of a millimetre than the diameter of the remaining piston portion 2, the control edges 20, 23 co-operating with edge 21 of the housing whereby in predetermined regions of the valve travel, different pressure rises are effected. In modifications, the control edge 20 is chamfered on four sides, or the portion 9 is made conical. In another form, the valve is of rotary sliding type. The device may be used in power-assisted steering systems for motor vehicles to give good " road feel." Thus in the plot, Fig. 2, of pressure against valve travel or force applied to the steering wheel, points A and B correspond to the respective control edges 20, 23 being aligned with control edge 21. In normal curve travel, the valve operates up to point B, whereas in parking, when the point B is passed, amplification of the force applied to the steering wheel assumes a much higher ratio.
