Title: Electronic circuit units and methods of making them
IPC: H01L23/538
Filed: 1966-03-10
Abstract: 1,144,741. Welding by pressure. SPERRY RAND CORP. 10 March, 1966 [22 March, 1965], No. 10625/66. Heading B3R. [Also in Division H1] An integrated circuit chip 28 has terminal areas on its lower surface which are bonded by ultrasonic welding to raised conductive pedestals 22 at terminal portions of printed wiring 20 on a transparent insulating substrate 10. The substrate 10 is made of glass or transparent plastics material; a layer of A1 or other metal is deposited by evaporation on one face thereof and photo-etched to produce the pedestals 22, after which the rest of the wiring 20 is deposited through a mask (Figs. 3a, b, c, not shown). Alternatively, the pedestals 22 are also deposited by evaporation through a mask. The substrate 10 is held by suction on a support 16, the position of which is adjustable by an X-Y micromanipulator 38, and a circuit chip 28 is transferred from a tray 30 to the substrate 10 by a pivoted holder 40 which is provided with a suction source 46 to enable the chip to be picked up and held. The positioning of the chip 28 on the substrate 10 is monitored visually by means of a lens system 53, a mirror 55 and an aperture 18 in the support 16. The chip 28 is welded to the pedestals 22 by a welding instrument 54 supplied with ultrasonic energy from a source thereof 52 through a suspension system 56 which acts as a harmonic suppressor. The welding instrument 54 may have a pointed tip (Fig. 5a, not shown) or a tapered tip with a recessed end (Fig. 5b, not shown).

Title: Improvements in or relating to methods of terminating electrical transmission lines and circuits therefor
IPC: H03F3/28
Filed: 1940-06-21
Abstract: 542,035. Valve amplifying circuits. BAIRD TELEVISION, Ltd., and McCONNELL, E. D. June 21, 1940, No. 10697. [Class 40 (v)] An electrical transmission line is terminated by a push-pull amplifier so arranged that more than half the signal is fed to each valve and wherein the cathode coupled impedance of the valves is equal to or greater than the characteristic impedance of the line. The Fig. 4 shows an arrangement in which the grids and cathodes are cross connected and the output is taken from load resistances 14, 15. Padding resistances 18A, 19A are connected between each side of the line and earth to reduce the terminating impedance to a desired value. If the valves are triodes the resistances 14, 15 may be used to increase the cathode coupled impedance to the requisite value. Resistances 20, 21 may, in addition, be provided so that the effect of unbalanced input signals and spurious voltages may be balanced out

Title: Improvements in or relating to fluid pressure relief valves applicable to high flow rate fuelling systems
IPC: G05D16/10
Filed: 1950-05-02
Abstract: 695,368. Fluid-actuated valves. ANGLOIRANIAN OIL CO., Ltd., and BREAR, N. H. Mav 1, 1951 [May 2, 1950], No. 10759/50. Class 135 A valve for relieving excessive pressure in a pipe line, whilst permitting unobstructed flow therethrough, comprises a valve body 4, Fig. 1, having a through passage 4A and a transverse bore 4C housing a valve member 2 urged towards closure by a spring 10 and formed with a hollow piston 6 of smaller effective diameter than that of the member 2. A rod 9 connects the member 2 to a control piston 3 slidable in an extension 4D of the bore 4C. Inner and outer rings of holes 14, 18 respectively through the member 2 connect opposite sides of the hollow piston, the inner ring 14 co-operating with a spring-pressed disc 13 so that when the valve member 2 is moved towards closure the inner ring is covered to provide a dashpot effect. The control piston 3 is subjected on its upper face to fluid pressure in the passage 4A and on its lower face to fluid pressure in the pipe some way downstream of the valve and communicated through a sensing line 21 so that the action of the spring 10 is supplemented when a pressure difference exists on its two faces. In a high flow rate system, e.g., for refueling an aircraft, having a fuel supply tank 31. Fig. 2, pump 33, filter 34, air separator 35, meter 39 and a stop valve 40 disposed in a pipe 38 which is connected to a supply hose 41, the relief valve 37 is placed between the air separator and the meter and its sensing line 21 connected to the delivery end of the hose where an appreciable fall in pressure occurs. Under no flow conditions, when a shut-off valve sited in the hose beyond the sensing point is closed, the pressures on the opposite sides of the piston 3 are equal and the valve 2 opens to relieve pressure when the spring 10 and the pressure of the fuel in the hollow piston 6 are overcome by fuel pressure in the passage 4A. Under flow conditions, a substantial pressure drop occurs between the valve and the delivery end of the hose with a corresponding pressure difference on opposite faces of the piston 3 assisting the spring 10 to hold the valve 2 closed which will not now open to relieve pressure until the pressure in the passage 4A has reached a considerably higher value than that under the no flow conditions. On a slow rise of pressure in passage 4A fuel will be expelled slowly from the hollow piston 6 and the inner ring of holes will remain covered. On a rapid rise of pressure, fuel will be expelled from the piston 6 through all the holes, the valve then opening more rapidly.

[Class 29] [Also in Group XXXV] The food compartment 22 is cooled by air drawn by a fan 38 over the evaporator 32, 34 surrounding a freezing compartment 26 separated from the food compartment by a glass shelf 24, the cold air passing through passages 36 around the food compartment and returning to the evaporator and the speed of the fan is controlled by a vibrator 62 responsive to the temperature in the storage compartment. A common door 28 provides access to the compartments, and the freezing compartment 26 is cooled through its bottom wall by serpentine tubing 32 supplied with refrigerant from a condenser 46 through a restrictor 52. The second portion of the evaporator comprises finned tubes 34 located in the air passage way beneath the fan 38 driven by a motor 40. Operation of the compressor 44 is controlled by a thermostat 56 in the freezing compartment, the temperature being adjusted by a knob 58. The fan motor 40 is controlled by a thermostat 62 in the food compartment, comprising a bimetal strip 74, Fig. 2, upon which is mounted an electric heater 72 in the motor circuit. A contact 76 on the bimetal strip engages a fixed contact 68 when the strip. is heated,. to short circuit the heater 72 whereupon the upward bending of the strip opens the contacts. The cycle of opening and closing the contacts is repeated rapidly and the speed of the fan motor is controlled in accordance with the percentage of time the contacts are closed, which is governed by the temperature of the food compartment 22. The, bimetal strip is adjusted by a screw 80.

The opening means preferably comprises a tear string 18 attached to the under surface of the sheet 16. In one example (Figs. 1 and 2) sheets 12, 14 of transparent plastics material coated on the surfaces 12c, 14c (Fig. 3) with thermoplastics material, e.g. polyethylene, are heat sealed at 26, 28 to a third sheet 16 coated on both sides with thermoplastic. The sheets 12, 14 are then heat sealed at 30 and after folding back flaps 20, 22 to prevent them being heat sealed to each other one of the seals 32 is made. The bag is then filled with the pasty material, any trapped air evacuated and the second seal 32 made. Transverse or longitudinal cuts 34 are made in the seals 32 so that the tear string 18 may be pulled without damaging the seals 32. In a second embodiment the envelope is formed from one sheet of film (Fig. 7, not shown) folded upon itself with a tear strip sealed adjacent the inside of the fold, the seal equivavalent to the seal 28 being set spaced sufficiently from the free edges parallel to the fold to permit the flaps so formed to be folded back against the bag sides and extend beyond the fold. In a third embodiment (Fig. 9, not shown) two sheets are sealed together to form an envelope as in Figs. 1, 2 but with one sheet providing both walls 14 and 16 and there being no flap 22. In both these embodiments tear limiting cuts are formed as before. The envelopes may be made by securing together webs corresponding to the sheets and forming them into tubes about a filling nozzle, filling and sealing them as in the usual tubular package forming process.
