Abstract: 1,051,937. Finishing yarns MONSANTO CO. Nov. 12, 1964 [Nov. 12, 1963], No. 46139/64. Heading D1F. Intermittently textured yarn is produced by underdrawing a thermoplastic continuous filament yarn so that it exhibits alternate thick and thin portions along the length thereof, subjecting the yarn to a texturing operation which may be accompanied by heating or preheating and subsequent cooling of the yarn, and stretching the yarn to complete the draw and so that the thin portions remain textured and the thick portions are untextured or straight. The yarn may be dyed before it is finally stretched so that textured and untextured portions show different shades of colour. The yarn filaments may be of a polyamide (nylon-6 or-66), polyester (polyethylene terephthalate), polyurethane, polyurea, polyacrylonitrile, polyethylene, polypropylene, polyvinyl chloride, or cellulose ester or ether, of circular, X or Y cross-section and/or tubular and/or have discontinuous voids therein. Texturing is by one or more passages of the yarn between toothed crimping wheels or gears, twist or false-twist curling or crimping, compressive crimping in a stuffer-box, knitting the yarn into a fabric which is then heat-set and unravelled, or hot plasticizing fluid-jet looping treatment. The yarn may be heat-relaxed before or after take-up on a package to enhance the crimp &c. and/or it may be stapled. Yarn production, i.e. from the filament-forming apparatus to the final take-up of stretched, textured yarn, or two or more stages thereof, may be continuous.

Abstract: 1,233,746. Anti-skid systems; testing braking systems. KELSEY-HAYES CO. 18 June, 1968 [19 June, 1967], No. 28921/68. Headings F2E and F2F. An anti-skid hydraulic control system for a vehicle includes a pressure modulating valve 24 which is caused to be cycled automatically each time the vehicle driver operates the vehicle ignition switch SW, a valve checking electrical circuit also being connected with the modulating valve 24 and responsive to a preselected deviation from the predetermined cycle of the valve 24 which is indicative of valve malfunction to provide an electric warning signal. As particularly described, the modulating valve 24 is connected between a master cylinder assembly 20 and the rear wheel brake cylinders 12. A solenoid 48 of the valve 24 is energizable by the output from wheel sensors 28 indicative of a skid condition to cause one side 50 of a diaphragm assembly 42 in a vacuum chamber housing 40 to be disconnected from vacuum and connected to atmosphere via line 56; this causes an hydraulic piston 46 to move within its cylinder housing 44 to increase the volume of cylinder housing 44 and simultaneously to close a check valve 76 to disconnect cylinder housing 44 from the master cylinder assembly 20. The pressure in cylinder 12 is thereby relieved. Cycling the valve: The coil 104 of solenoid 48 is also connected between earth and the positive terminal B+ of a battery via a transistor Q1 and switches SW1, SW2 of ignition switch SW. Switch SW2 and a further switch SW2a are closed when the ignition is turned on, and switch SW1 is also closed when the engine of the vehicle is started; hence when the engine is started the coil 104 is energized and the valve 24 is cycled. Checking the valve cycle: A switch SW3 is maintained open by contact with diaphragm assembly 42 when its side 50 is connected to vacuum and is closed when the assembly 42 moves a predetermined distance. Closing of switch SW1 on starting the engine causes a capacitor C1 of a first timing circuit to be charged and the charge after a pre-set time will cause a normally non-conductive uni-junction transistor UJ1 to conduct to trigger a siliconcontrolled rectifier SCR1 to light a warning lamp L. However, this will only happen if the switch SW3 has not closed-if this has occurred a transistor Q3 is rendered conductive through which the capacitor Cl will discharge. Thus in this part of the cycle ignition of the lamp L indicates that the assembly 42 has not been displaced or has been displaced too slowly. To check that the assembly 42 returns in a preset time a capacitor C2 of a second timing circuit is charged through a transistor Q2 from terminal B+ from the moment switch SW1 is opened and coil 104 is de-energized. After a preset time the charge on capacitor C2 will cause transistor UJ2 and rectifier SCR2 to conduct to lamp L, if a transistor Q4 is not rendered conductive in this time by re-opening of the switch SW3. Additionally the output from deceleration sensor 28 is connected to these circuits via a control module 26 to check the operation of the valve each time the sensor 38 transmits a signal.

The sprue 1 is extracted from the inlet channel of an injection mould by first exposing the sprue by removing a member 2 which forms an extension of the mould channel, then gripping the sprue and removing it by means of a pair of jaws 11, 12. The member 2 is carried by a lever 3 which is pivoted about a pin 4 when a projection 5 is engaged by a lever 17 carried by a cylinder 6. The jaws 11, 12 are pivoted on a pin 10 carried by a ram 9 in the cylinder 6. The cylinder 6 is moved by an hydraulic cylinder 7. When an abutment 16 on a rod 14 secured to ram 9 engages a stop 8, the ram 9 is stopped and the cylinder 6 continues its travel, thereby closing the jaws 11, 12 on the sprue 1. When the cylinders 6, 7 are reversed, the jaws 11, 12 remain closed until a second abutment 15 engages the stop 8.

Abstract: 1,234,245. Automatic steering control systems. JERVIS B. WEBB CO. Aug. 8, 1968 [Aug. 9, 1967], No.37788/68, Heading G3R. In a vehicle guidance system for regulating the operation of the vehicle steering mechanism to follow a guide path defined by an energized wire on or beneath the surface on which the vehicle travels, comprising left and right hand sensing units 26<SP>1</SP>, 27<SP>1</SP> each producing an error signal proportional to the extent of the deviation to the left or right of the guide path; a supply voltage 74; means 60, 61, 62 and 64, 65, 66 for amplifying the error signals; and means e.g. reversible motor 22, for controlling the steering mechanism in accordance with the difference between the amplified error signals, variations in the field intensity of the wire along its length are compensated by means of a summation network R1, R2 which produces a voltage at 70 proportional to the sum of the error signals, a circuit arrangement e.g. transistor Q1 which compares the summation voltage 70 with a reference voltage divided off by resistors R4, R5 from a supply 74, 75 and produces a control signal proportional to the difference in summation and reference voltage which is used to control the gain of the two error signal producing circuits so that the summation voltage is maintained constant. As shown, each sensing unit e.g. coil 26<SP>1</SP> produces an error signal which is amplified by A, C, amplifier 60, detector 61 and D.C. amplifier 62 to produce a D.C. voltage on motor 22. When the summation voltage at 70 is less than the reference voltage at base 76 of transistor Q-1, transistor Q-1 conducts, a portion of the output being divided off by resistors R7, R8 to produce a control signal proportional to the difference between the reference and summation voltage at terminal 78. This control voltage is applied to the gates of left and right hand field effect transistors QL, and QR. When the control voltage is negative i.e. the reference voltage exceeds the summation voltage, the transistors QR, QL are progressively turned off so that less current from the sensing coils 26<SP>1</SP>, 27<SP>1</SP> is shunted through them. When the summation voltage exceeds the reference voltage transistor Q-1 becomes positive, and the fluid effect transistors QL-QR, which act as voltage variable resistors, are progressively turned on thereby shunting more of the error signals and tending to maintain the summation voltage constant. When the reference voltage exceeds the summation voltage by an amount determined by variable resistor 91 relay CR will be energized through amplifier 90 to open contacts CR-1 in the drive motor 16 circuit of the vehicle, thereby stopping the vehicle. This happens when the vehicle deviates more than a predetermined amount from the guide path. The axes of the sensing coils 26<SP>1</SP>, 27<SP>1</SP> are inclined to the guide path and at about 10 degrees to the horizontal.

[Also in Division A6] A propulsion unit for a flying toy comprises a substantially cylindrical shaft, a drive spring 2 being helically wound around the shaft and connected to it at one end of the spring 3. The other end of the spring abuts against a flange on the shaft at 5 and is connected to the casing 9 of the unit at 7. A cap 11 fits on to the lower part of the easing 9 and is held in position by tongues and recesses, the cap providing a bearing 21 for the lower end of the shaft. The upper end of the shaft is ratchet-shaped to engage a corresponding ratchet surface on a propeller blade of a toy, while the lower end of the shaft carries a ratchet which engages a pawl 27. The pawl 27 is biased by flexible projections 32 of the pawl which abut against the casing 9, and is supported in the casing by parts 28 and 29 which mate with recesses in the casing, so that when pressure is applied at 28 the pawl disengages from the ratchet and when the part 28 is released the ratchet re-engages the pawl. The toy is fitted on to the upper end of the drive shaft and manually rotated to tension the drive spring, this rotation being allowed by the ratchet. When the part 28 is operated the spring rotates the shaft, rotating the propeller of the toy which lifts the toy from the shaft. In a further embodiment, a pedal lever is used to release the ratchet; the pedal lever is pivoted to the casing 9 and attached by a tie rod to a pawl, so that depression of the pedal moves this pawl, and a projection on this pawl co-operates with a projection on the lower face of the pawl 27, allowing the drive shaft to rotate. Varying numbers of the propulsion units may be mounted on a common base to power several toys. The unit may also be permanently attached to the propeller blade of the toy. In a further embodiment, the unit and the flying toy may be used in a shooting game, the toy being shot at in flight (see Division A6).
