Title: Integrated circuit arrangements
IPC: H03F1/30
Filed: 1969-06-26
Abstract: 1278298 Transistor amplifying circuits PHIL. IPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 June 1969 [29 June 1968] 32371/69 Heading H3T [Also in Division H1] Drift occurring during operation of an IGFET, and thought to arise as a result of ion migration in the gate insulation, is offset by varying the operating temperature of the transistor. These temperature variations are occasioned by varying the current fed to a heating resistor associated or integrated with the substrate. The heating current is derived from the drain of a transistor T 2  identical to that being stabilized (amplifier T 1 )-identical in characteristics and in source and drain loading and equally affected by the heater-the transistors being co-integrated. As shown the output V 0 <SP>1</SP> of the stabilizing transistor is compared with a reference voltage V r  by an amplifier comprising bipolar or insulated gate transistors and which may be co-integrated on the same substrate, the amplifier controlling the current to the heater W. In a particular embodiment (Fig. 2, not shown) the identical drain resistors Rd lie outside the controlled temperature area so that heat generated therein will not affect the transistors. The source resistors may also lie outside the controlled area. Many identical transistors may be placed in the controlled area to stabilize their characteristics.

Title: Thread controlling mechanism for sewing machines
IPC: D05B49/02
Filed: 1919-12-29
Abstract: 160,295. Fairweather, W., (Singer Manufacturing Co.). Dec. 29, 1919. Sewing-machines; loop stitching; governing needle thread.-In a machine making a stitch as shown in Fig. 9 by means of an eyed needle 1 and a hooked needle 2 and more particularly intended for straw-plait sewing, the stroke of the take-up lever and the timing of the thread lock are varied automatically as the length of feed is varied. The take-up arm 26, Fig. 3, is integral with a lever 28 pivoted near its middle on the free end of a lever arm 30. The lower end of the lever 28 is connected directly to an eccentric-rod 32 and the upper end is connected by a link 34 with an eccentric sheave 37 which actuates the feed shaft. As explained in Specification 159,701, the feed is varied by swinging the eccentric sheave 37 and its rod about the eccentric itself and in doing this the amplitude and the field of the take-up vibration is varied. A thread lock, Fig. 4, comprises an eccentric-actuated member 38 and a spring-pressed member 48 the position of which is determined by a containing sleeve 50. The sleeve has an oblique slot engaged by a pin 44 and is so connected to the feed regulator that the sleeve is turned and consequently moved axially as the feed is varied. The combined effect of the adjustment of the take-up and the thread lock is to cause the take-up to operate as a pulloff when the stitches are long and as a take-up when the stitches are short.

Title: Shutter button assembly for a photographic camera
IPC: G03B17/42
Filed: 1971-07-12
Abstract: 1340374 Photographic cameras ASAHI KOGAKU KOGYO K K 12 July 1971 [16 July 1970] 32639/71 Heading G2A In a camera, a non-rotatable shutter button 1 housed in a seat 2 co-operates with a rotatable member 4 coupled with a film transport lever 5 such that in one position, an engaging piece 4a on the rotatable member engages a projection 1a on the button to prevent depression of the latter. The lever 5 is movable from this one position, i.e. a storage position, to another position in which it is actuable to move the film through co-operation of member 4 with a gear (14), Fig. 1, (not shown), through a ratchet wheel (13) and ratchet (11). Button 1 is restrained from rotation in seat 2 by stops 3a, 3b and rotatable member has a groove 3b on its lower side for engagement with one end of a leaf spring 6, rotatable about a pin 20, in the storage position. To actuate film movement, lever 5 is moved anti-clockwise against a spring (9) whereby member 4 engages a projection 7a on ratchet support (7) to move gear (13). This motion disengages projections 1a and 4a so allowing depression of the button on demand. The spring (9) restores the position of member 4 on completion of film movement whereby a stop 7b engages a control plate 8, and projections 1a and 4a engage again, to lock the button when the lever 5 is further rotated clockwise, and leaf spring 6 engages in groove 4b, the stop 7b preventing any film movement during this movement. A notch on the button 1 co-operating with an engaging piece 4a may also lock the button, alternatively the button may have a projection engaging with a notch on member 4 so allowing depression of the button when the two are aligned.

Filed: 1974-07-29
Abstract: 1446514 Automatic choke valves FORD MOTOR CO Ltd 29 July 1974 [6 Aug 1973] 33365/74 Heading F1B An automatic choke system for use with a carburetter having an air/fuel induction passage and an unbalance mounted choke valve comprises a first temperature responsive spring means which urges the choke valve towards the closed position with a force which increases as the temperature of the spring decreases from a first predetermined temperature, power means adapted to be connected to engine manifold vacuum to move the choke valve towards an open position in opposition to the action of the first spring means and second temperature responsive spring means connected to the power means for controlling the effect of the power means on the choke valve as a function of the temperature changes of the second means from a second predetermined level. Choke valve 28 is mounted on a spindle 30 and at one end has a lever arm connected by link 52 to arm 48 on shaft 44 which carries arm 58 attached to the outer end of coiled bi-metal strip 60. When cold, strip 60 turns choke valve 28 to its closed position. Hot gas is drawn through housing 42 by manifold vacuum to heat strip 60 and turn choke valve 28 towards its open position. At the other end of spindle 30 is fixed a second lever 90 which is engaged by pin 92 carried by one arm 94 of bellcrank 96, fixed on shaft 98 which is mounted in bearings 100 in bracket 102. A second coiled bi-metal strip 122 has its inner coil fixed to the other end of shaft 98. Freely mounted on shaft 98 is a yoke 112 which carries a screw 108 which can engage the other arm 106 of bell-crank 96. Yoke 112 also carries a pin 114, which passes through the eye of a pull rod 118 and is attached to the outer end of coiled strip 122. Pull rod 118 is attached to diaphragm 128 of a vacuum operated motor. One side of diaphragm 128 is open to atmosphere through a restricted orifice 140 and a check-valve 144. Tension spring 134 connects the first diaphragm to a second diaphragm 130, one side of which is connected by passages 152, 154, 156 to the intake manifold, downstream of throttle valve 26. Operation. In cold weather, strip 60 shuts choke valve. Screw 108 is adjusted to separate lever 96 from finger 110 to unwind spring 122 by an amount sufficient to provide an initial load opposing movement of pull rod 118 so that manifold vacuum during engine cranking will not move diaphragm 130 against the force of coiled strip 60. As soon as the engine starts, the increased manifold vacuum will be sufficient to move diaphragm 130 downwardly (to the position shown in Fig. 4) and through spring 134 will pull diaphragm 128 downwardly at a rate determined by the passage of air through orifices 149 and 148, thus opening the choke valve by a small amount e.g. 6 degrees. As the engine temperature increases, the force exerted by coiled strip 60 decreases and allows the choke valve to open. When the ambient temperature is above a predetermined level, coiled strip 122 will rotate lever 106 to open the choke valve in accordance with the ambient temperature.

Abstract: 366,568. Wireless receiving systems. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.- (Tournier, M. C. ; 46, Avenue de Breteuil, Paris.) Nov. 6, 1930, No. 33368. [Class 40 (v).] The carrier wave and the side bands are separated by a mechanical vibrator, e.g. a piezo crystal, at the receiving-station, and are recombined in the detector after separate amplification. As shown in Fig. 1, the incoming signals are amplified in a valve 4 and are then applied in parallel to amplifiers 8, 10. The amplifier 8 is not selective to a particular frequency, and in consequence amplifies the side-bands. The amplifier 10 is made very selective by the use of a crystal input coupling 7 or a magneto-strictive or other electromechanical oscillator which passes practically only the carrier wave. The outputs are recombined in the transformer 11 and applied to a detector 12 followed by an audio amplifier 14. In the modification shown in Fig. 2, the incoming signals are received on a broadlytuned aerial, and are combined with oscillations from a local source 18 which is tunable. The supersonic beats appearing in the plate circuit 19 of the valve 16 are applied (1) to a screengrid valve 20 the plate circuit of which is coupled through a crystal coupling 7 to the grid circuit of another amplifier 10, which has its tuned plate circuit 21 coupled to the plate circuit of a detector valve 12 and (2) to the grid circuit of the detector valve 12. The beat wave and its side bands are thus separately amplified and are recombined in the detector to produce audio-signals in the amplifier 8, 14 and telephone 15.
