Title: Improvements in electronic fuel control systems
IPC: F02D41/06
Filed: 1971-05-27
Abstract: 1292771 Fuel injection systems BENDIX CORP 27 May 1971 [16 June 1970] 17548/71 Heading G1N In an I.C. engine fuel injection control system, a circuit is provided to produce a single pulse to control, in dependence upon engine temperature below a selected value, the actuation of injection valve means during starting to provide a quantity of fuel sufficient therefor, the circuit being automatically disabled when the temperature has reached said selected value. As shown, Fig.1, the system includes a transistor 20 which, for each injection synchronized with engine rotation, provides two sequential control pulses, the first being derived from a monostable multivibrator 28, 30 in synchronism with engine rotation and of duration dependent upon intake air pressure (sensor 12), and being applied to transistor 20 via resistor 22, and the second pulse being derived via diode 50 and transistor 46 in dependence upon the charge on capacitor 40 being applied to transistor 20 via resistor 24, the second pulse having a duration dependent upon the duration of the first pulse and upon engine temperature (thermistor 14). The cold start circuit 100 Fig.2, is connected  at point A, and upon energisation, when starting the engine, applies a single pulse at 102 to an additional injector situated independently of the main injectors. Upon energisation, the circuit 100 immediately initiates the pulse, (except when engine temperature has reached said value), whose duration is determined by the time taken for the charge on a capacitor 120 to reach the voltage at point A (dependent upon engine temperature below said value). A zener diode 104 is provided to compensate for supply voltage variations and the circuit is arranged such that, after the supply has been removed, a pulse at 102 cannot be provided upon re-energisation until capacitor 120 is fully discharged. Thereby, flooding is prevented.

Abstract: 1,163,390. Powder metallurgy. CRUCIBLE STEEL CO. OF AMERICA. April 11, 1968 [May 24, 1967], No. 17719/68. Heading C7D. In a process of producing sintered metal articles such as tool steel, the metal powder is placed in a container and heated to a compacting temperature below the fusion temperature of the metal, and the heated container and charge are then compacted in a fluid-pressure vessel such as an autoclave, to a density of at least 95%, the compaction being compacted before the temperature falls below the selected compacting temperature. The powder used is preferably finer than 30 mesh (U.S. sieve) and it may be precompacted to e.g. 60% density in the container and outgassed during the heating step by connecting to a vacuum. For tool steel the powder is heated to 1300‹ -2200‹ F. and compacted with helium in an autoclave at 10,000-30,000 p.s.i. The time of heating must be sufficient to ensure that the whole powder charge is at the desired temperature.

Title: Conductor having distributed capacitance and method of making same
IPC: H01B11/18
Filed: 1964-05-01
Abstract: 1,062,242. Conductors; capacitors; delay lines. GLOBE-UNION Inc. May 1, 1964 [July 30, 1963], No. 18129/64. Headings H1A, HIM and HlW. An elongate conductor with distributed capacitance has an oxide insulating layer formed between an inner main conductor and an outside conducting layer. The inner conductor comprises an oxidizable metal such as nickel, titanium, aluminium, or tantalum and may have a core of copper or silver. As described, the inner conductor is coated with a conductive, oxygen-permeable silver paint and is heated in an oxygen-containing atmosphere to form the oxide layer. The inner conductor may be bent to shape before the treatment and the oxygenpermeable silver paint may be applied only in selected sections and other sections may be covered with masking paint to inhibit their oxidation. When the conductor is used, for example, in a T.V. tuner, its distributed capacitance provides a by-pass for unwanted high frequencies. The distributed inductance of the conductor may be increased, if required, by forming it into a helix, which may be coated with, or embedded in ferromagnetic material, and the conductor may then be used as a delay line.

Title: Improved apparatus for tempering glass articles
IPC: C03B27/03
Filed: 1936-06-30
Abstract: 477,414. Tempering glass; furnaces for treating glass. CORNING GLASS WORKS. June 30, 1936, No. 18167. Convention date, Sept. 24, 1935. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 2, 1937.] [Class 56] [Also in Group XII] Apparatus for tempering glass articles comprises a heating-device, means for immersing the articles in a chilling bath composed of molten inorganic salt, and means for transferring the chilled articles to a water bath. The glass articles, such as dishes, are shaped by a press 12, Fig. 1, from molten glass delivered from a tank furnace 11. On removal from the mould, each article is delivered by a conveyer 14 on to a shelf 76 in front of the opening 30, Fig. 3, in a heating-kiln 15, and is thrust into the kiln by a pneumaticallyoperated pusher 33. The kiln consists of an annular muffle 26 heated by gases in the tunnel 25 and provided with an annular floor 28 carried by a rotating vertical shaft 74. In order to prevent the articles from sticking to the floor 28, it is covered with a layer of pulverulent refractory material such as hydrated alumina, or potassium sulphate, or a mixture of 23 per cent of hydrated alumina with 70 per cent of diatomaceous earth and 7 per cent of felspar. The article is carried through the muffle to an exit opening through which it is withdrawn by a pneumatically-operated fork, and it drops into a molten mixture of inorganic salts contained in an annular trough 41, Fig. 7. Instead of the kiln 15, a bath of molten inorganic salt may be used to equalize and adjust the temperature of the articles removed from the press moulds. Compositions of the baths, both for heating and chilling, are given in Specification 477,585. The article is received in a perforated container 52 formed of wire mesh, a number of which are attached to a spider frame 47. The spider is secured to a rotating shaft 46 which is inclined to the vertical at such an angle that each container is dipped into and raised out of the annular trough 41. The articles are chilled in the molten salt, and when a container reaches its highest position, the bottom 54 is opened by a cam and the contained article is discharged on to a rotating table 78, Fig. 1, and is deposited on a conveyer 64. This conveyer carries the articles through a housing 63 in which they are submitted to an air blast to cool them, and they are then immersed in water in a trough 17 through which they are carried by a conveyer 70. The water washes off the articles any salt from the chilling bath. The washed articles are then carried by a conveyer 71 through a housing 72 into which steam is introduced. The steam completes the cleaning of the articles and heats them sufficiently to cause rapid drying on the inspection conveyer 20.

Filed: 1948-07-07
Abstract: 657,694. Looms with stationary weft supply. COLIBERT, R. R. F., and BOURLET. E. July 7, 1948, No. 18263. Convention date, July 12, 1947. [Class 142(ii)] Weft is inserted from each side of a warp alternately by a dummy shuttle comprising a thread gripping member and a member which is propelled through the shed by a picking stick and carries the gripping member. The gripping member comprises a soft iron portion 25 and a stud 26 which grips the weft 31. A piece of spring wire 29 causes the gripping action. The stud stud 26 is raised to grip the weft by the plunger of an electromagnet positioned beneath the shuttle race. The carrying member 32 comprises a wooden body in the shape of the usual shuttle and carries a permanent magnet 34 having poles 35. After picking, the member 32 passes over the gripping member and an electromagnet positioned above the gripping member causes the magnet 34 to attract the gripping member and carry it through the shed. The gripping member is stopped after it leaves the shed by a stop and is held against this stop, and immediately above the finger which raises the stud 26, by a finger operated by an electromagnet. The gripping member is held down on the shuttle race during the raising of the stud 26 by an electromagnet positioned beneath the shuttle race or by the gripping member entering a groove or by mechanical means. The weft is presented to the gripping member by a transfer device 48 which is rocked by an electromagnet 59 to grasp one of the wefts projecting from a thread guide box 46. The guide box 46 is reciprocated in the direction of the double-headed arrow A according to which weft is to be grasped by the transfer device. While the device 48 is moving towards .the guide box, a cam 55 moves a sliding member to open the jaws 49. The jaws are closed on a weft end when the end 54 of the sliding member engages a notch on the cam. The inserted weft is cut by movable blades 65 operated by an electromagnet. The various electromagnets are operated by cams keyed on the main shaft. A selvedge is formed by directing a current of compressed air on to the weft end and blowing it into the shed. The compressed air may be obtained from a bellows attached to the slay. The gripping, cutting, and positioning mechanism may be adjusted laterally to allow the weaving of fabrics of different widths.

Abstract: 1,187,569. Fixing developed images. ARLSIDE Ltd. April 24, 1967 [April 28, 1966], No.18684/66. Heading G2H. Electro-photographic apparatus includes a heater unit as disclosed in Specification 1,083,692 and is characterized in that a temperature sensitive switch 52 is arranged to regulate the temperature within the heater unit except when a sheet of copy material is within the unit. The copying process is effected in the same manner as that of the above Specification. The elements 41 of the heater unit which are connected in series with the thermostat 52, are energized by the closing of a main switch of the apparatus or by the tripping of a first micro-switch MS1 on insertion into the apparatus of an original to be copied. A micro-switch MS5 is tripped by the original just before the leading edge of the sheet of copy material enters the heater unit and in turn actuates a further switch to by-pass the thermostat 52. A second thermostat 53 acts as a safety switch, and opens when the temperature in the heater unit exceeds a set upper limit. The thermostat 52 becomes operative again when the trailing edge of the original frees the micro-switch MS5. Air is supplied by a fan to the main space within the heater unit whenever the heater elements 41 are thermostatically controlled by the switch 52.
