IPC: B21D47/00
Filed: 1969-12-18
Abstract: 1,258,830. Welding by pressure. BOEING CO. 18 Dec., 1969 [27 Dec., 1968], No. 61786/69. Heading B3R. A method of welding a cellular core component to face sheets sandwiching the core comprising spacing at least one sheet from the core component by heat yieldable spacer means in a furnace and elevating the temperature so that the spacer means yield and the components are brought into mutual engagement for bonding. As shown in Fig. 2 a cellular titanium core 10 is bonded between an upper sheet 12 and a lower sheet 14. The upper sheet 12 is initially supported on heat yieldable borosilicate glass spacer means 16 which space the sheet 12 from the core 10 resting on a further sheet 14. Alternatively both face sheets may be spaced from the core by glass spacer means. The sheets 12, 14 are formed of Ti-6A1-4V. Borosilicate pads 22, 24 are employed for even distribution of the pressure by a dead weight 26. The furnace is evacuated and the temperature raised until the glass supports yield so that the upper face sheet 12 contacts the core 10. The furnace is additionally heated to secure a uniform diffusion bond between the core and two sheets. The sheet 12 may be further supported by a wire 28 spot welded to the sheet and the other end hooked to a supported glass rod 30 which softens and yields with the supports 16. To prevent the glass pads 22, 24 adhering to the sheets 12, 14 the sheets are coated with a water slurry of boron nitride, zirconia or other ceramic oxide. Guides 36 having guide arms 38 may be positioned to prevent dislodgement of the cellular core 10 and upper sheet 12. Alternative pressure applying means to the dead weight 26 may be employed such as a pneumatic diaphragm, electromechanical solenoid, hydraulic ram or mechanical leverage. An inert gas such as argon may be introduced into the evacuated furnace before bonding so that the gas is trapped at a high pressure in the cells of the bonded structure. Other materials such as beryllium, stainless steel, molybdenum, niobium, tungsten may be used for the core 10 which may have hexagonal, square, rectangular, or pentagonal cross-sectional configuration. Core 10 may further comprise a sponge-like metallic matrix.

Abstract: 1288990 Colour television PHILIPS ELECTRONIZ & ASSOCIATED INDUSTRIES Ltd 16 Dec 1970 [19 Dec 1969] 59703/70 Heading H4F In a PAL switch circuit arrangement in which a direct voltage is produced in response to erroneous phase operation of the PAL switch, this voltage being supplied to the switch to stop it, a delayed direct voltage is derived from the switch when in its stopped condition which is supplied to the circuit arrangement in a sense such as to suppress the stopping action of the switch. Thus the switch always restarts after which both direct voltages disappear until an incorrect switching phase again occurs. This circuit arrangement prevents the switch being permanently stopped when a continuous direct voltage is produced due to an erroneous reference oscillator-burst signal phase relationship occurring when the switch is stopped. As shown, a reference subcarrier signal is supplied to terminal 9, and received colour synchronizing (swinging burst) signals in opposite phases are supplied to terminals 1 and 2. The phase of the reference signal is changed in synchronism with the change in phase of the swinging burst by means of the PAL switch which operates at halfline frequency. If the switch is operating in the correct phase a negative voltage appears across output capacitor 11 and transistor 13 is cut-off. The PAL switch, which may be externally synchronized, comprises transistors 14 and 15 which form a multivibrator, their bases and collectors being crossconnected in a supply network 16 so that a square-wave is produced. If transistor 13 is turned-on by a positive direct base voltage, transistor 14 is cut-off and the multivibrator stops. As a result the phase of the switch is corrected, the positive input voltage to transistor 13 disappears and the multivibrator continues to operate in the correct phase. However if the phase relation between the burst signals and the reference signal differs from the desired value a positive direct voltage may appear across capacitor 11 even when the multivibrator is stopped, and this voltage will drive transistor 13 continuously thus permanently stopping the multivibrator 14, 15, 16. To overcome this, the emitters of transistors 14 and 15 are coupled with each other via large capacitor 19 and to earth via individual resistors 20, 21. In normal operation with transistors 14 and 15 alternately conducting no voltage appears across capacitor 19. This situation is not changed in any way if the switch is stopped for a short time for phase correction. But if the switch is stopped for any length of time capacitor 19 charges causing a negative baseemitter voltage to be applied to transistor 13 so that it is cut-off and the multivibrator is restarted.

As shown the operating lever 3 pivots on a pin 25 and is connected by way of a connecting lever 26 and a pin 31 to a hinge joint 15, spring-loaded by a spring 29, this joint coacting with the roller 27 which is mounted on pins in grooves 22 of a yoke 13 connected to the diaphragm, and which fits into a tooth 23 in a hollow valve lifter 10, spring-loaded by a spring 12 and having a spring within it which acts on the valve cone 8. In operation the lever 3 is moved up, there being teeth in the body 1 of the gun to hold the lever in this position, this movement causing, through the hinge joint 15, the roller 27 to open the valve, the roller being in tooth 23 of the valve lifter 10. The flow of liquid draws air from the chamber 18 through the passage 19, which air is replenished by air from the orifice 16 supplied through the tube 17 unless the orifice 16 is immersed in the liquid, in which case a vacuum is created in chamber 18, the diaphragm lifts the yoke 13 and the roller 27 thus releasing the roller 27 from the tooth 23 and allowing the valve to close due to the action of spring 12. The apparatus can be used in refuelling stations.

Abstract: 1339776 Press brakes HURCO MFG CO Inc 11 May 1971 [25 May 1970] 14208/71 Heading B3E A guage bar 27 of a press brake is pivotally mounted on supports 23 and 24 by a pair of connectors 28 and 29 and is counter-balanced with respect to the pivot axis so that interference between the guaging bar and a flange 64 already formed on the workpiece 61 being bent is prevented by the upward pivoting of the guage bar. The gauge bar has a vertical flange 31 and is mounted in a slot 30 in each of the connectors 28 and 29 such that the gauge bar is prevented from reaching the end of the slot by a spring-loaded ball plunger 41. During adjustment of the supports 23 and 24 towards and away from the press brake, the gauge bar can squeeze under the ball plunger and so allow a small amount of skew between the supports. Each support has a slot 48 supporting a shaft 52 for pivotally supporting a connector. The shafts are vertically slidable in the slots so that the raising of the supports one at a time is facilitated. In another embodiment a pair of fingers 84, each having a flattened end portion 101 (Fig. 5), are clamped on to the flange 31 of the gauge bar. Ball plungers 91 engage a pair of detents 88 in each of the fingers so that the fingers can be pivoted upwardly. The flattened end portion 101 may be positioned horizontally by manually rotating the fingers through 90 degrees so that the plunger 91 engage a pair of detents 86 in each finger.

To overcome this a slit aperture 5 is placed at the prime focal point of the lens 1, the slit running parallel to the grating lines, such that all light rays, irrespective of their origin (distance of object 2) have to pass through the slit whereby of a lens of constant focus is simulated. To increase the angle of view of lens 1 a plurality of parallel slits, Fig. 2 (not shown), may be provided admitting light beams from various angles via lens 1. A mirror may also be used to direct additional light through the lens, Fig. 3 (not shown).
