Filed: 1974-09-25
Abstract: 1451021 Tyre underinflation indicating system GOODYEAR TIRE & RUBBER CO 25 Sept 1974 [12 Oct 1973] 41630/74 Heading B7C A pulse generator 58 coupled to a first, 34, of "n" conventional individual circuits in a vehicle provides pulses of insufficient power to affect normal circuit operation which are accumulated by circuit means C1, D1 coupled to the first circuit to provide a continual source of D.C. power to at least one condition monitoring circuit. A gating circuit intercoupling the monitoring circuit or circuits, the first circuit and a second, 48, of the "n" circuits, gates pulses from the first circuit to the second circuit in response to the output of the monitoring circuit or circuits, and circuit means D2, C2, R2 coupling a warning indicator 80 to the second circuit detects the presence or absence of pulses to provide an input to the warning indicator indicative of the monitored condition or conditions as reflected by the presence or absence of the pulses. As illustrated an articulated vehicle comprises a system for indicating underinflation of the tyres of the trailer. The system utilizes the braking and direction indicating circuits which includes battery 18, brake-operated switch 22, flasher unit 38, direction indicator switch 40 and brake lights 28, 30 and direction indicator lamps 46, 52. Pulses from pulse generator 58 are transmitted via brake line 34 to (a) capacitor C1 which supplies voltage to condition monitors 62-68, (b) transistors Q3, Q5 and (c) transistors Q6, Q7. A pressure sensor on each of the four wheels (not shown) remains closed while the pressure is at or above a predetermined value and transmits, on each revolution, a pulse to the respective condition monitor. These pulses are stored in the condition monitor and cause the latter to render the associated transistor conductive. If the pressure of a tyre is below the predetermined value its transistor will be non-conductive.  When the transistors Q4, Q5 are both conductive, the transistor Q7 will also be conductive and will cause pulses from the generator 58 to be returned along lines 54, 44 to charge a capacitor C3 which supplies a voltage to a "normal condition" lamp 86. Similarly a "normal condition" lamp 82 is illuminated when transistors Q2, Q3 are both conductive. "Abnormal condition" lamps 84, 88 are illuminated when transistors Q6, Q7, respectively, are non-conductive. Pulses supplied by generator 58 and passing along lines 34, 48, 54 are not sufficient to illuminate lamps 28, 30, 46, 52, but are sufficient to slightly heat their filaments. The system may utilize the main light circuit lines.

Abstract: 1,160,428. Non-woven fabric, yarns, finishing fabrics, paper. IMPERIAL CHEMICAL INDUSTRIES Ltd. 15 Sept., 1967 [20 Sept., 1966], No. 41859/66. Headings D1R, D1S, D1W, D2A and D2B. A bonded fibrous material is made by forming composite "fibres" into a fibrous structure and heating to render one of the fibre components adhesive so as to bond the fibres to each other. The composite fibres comprise at least two immiscible polymers, at least one of which is dispersed in the other(s) and at least one of which, but not all, is rendered adhesive by heating under conditions which leave the other polymer(s) unaffected. The polymers may be polyolefins, polyamides, polyesters, poly (epsiton caprolactam), poly (aminoundecanoic acid) and copolymers thereof. Pigments, brightners, stabilisers and dispersing agents may also be present in the fibres. The term "fibres" includes staple and flock fibres and continuous filaments. The heating may be by air, hot plates or rolls, radiant heat, ultrasonic or dielectric treatment, or steam. The composite fibres may be blended with non- activatable fibres, e.g. wool, silk, flax, cotton, regenerated cellulose, asbestos, rock wool, polyamides and polyesters. The fibrous structure may be a non-woven, woven or knitted fabric, yarn, plied cord or paper if the fibres are less than 0.5" long. The heating stabilises the yarns and fabrics and prevents fibre slipping or laddering. Yarns containing the composite fibres can be used to make scrims or reinforce sheets of plastic. The non-woven material can be formed from (a) fibres by carding, garnetting or cros slapping or air-laying or wet-laying onto a flat or shaped screen, or (b) filaments by collection on a stationary, oscillating, rotating or advancing surface. The non-woven web can be needled.

Abstract: 1,204,518. Grinding; lead screw drives. LANDIS TOOL CO. 15 Sept., 1967 [16 Sept., 1966], No. 42063/67. Headings B3B and B3D. The feedscrew 20 in a grinding machine is rotated by rotatable positioning means 53 before a machining operation and by feed actuating means 40 during a machining operation, transmission means 52 being provided to connect the feedscrew to both the positioning means and the actuating means such that the feedscrew is rotatable independently by each of the two means. The machine may be operated by dial switches or punch-card, to grind a series of different diameters on a workpiece W with a grinding wheel 16. Rapid feed movement of the grinding wheel is first effected by a piston 21  which moves the feedscrew 20 axially, the grinding feed then being effected by a piston 30 or a hand wheel 29; if the work has not yet been ground to the desired dimension, the feed actuating means 40 (a ratchet mechanism) is initiated by pistons 47, 49 to rotate the feedscrew incrementally. When a caliper 18 signals that the workpiece W has been ground to size, the pistons 21, 30 and the ratchet mechanism 40 are reversed to retract the grinding wheel. For grinding widely varying diameters, rapid rotation of feedscrew 20 is effected by the positioning means 53 (hydraulic motor 58 and electrical brake 68). The transmission means 52 consists of differential gearing, Figs. 4 and 5 (not shown), the output drive shaft 37 for rotating the feedscrew 20 being rotated either by an input shaft 54 driven by the motor 58 or by a worm gear 42 of the ratchet mechanism 40 when the shaft 54 is locked against rotation. Control of the brake 68 and motor 58 is through an electrical control panel 88 and a solenoid-operated valve 60 in the hydraulic circuit. Push buttons PBA and PBR may be used to control the valve 60 and position the grinding wheel, the position being read on an indicator 86; if desired, this position may be obtained by setting dial switches 85. A selector 110 is provided to change the control from the dial switches 85 to a punch-card reader.

Filed: 1970-09-04
Abstract: 1319819 Television RCA CORPORATION 4 Sept 1970 [11 Sept 1969] 42390/70 Heading H4F Telecine apparatus, particularly when used with monochromatic film comprising spatially encoded colour information, e.g. in the form of a fine structure of colour representative strips oriented vertically and/or obliquely to the horizontal dimension of the film frames, requires that images of successive frames are identically registered on the pick-up tube. In the apparatus described, which is for use with a film bearing a lateral reference position window 15 for each frame, and ensures correct lateral positioning of the image, the film is driven intermittently through a gate 11 and an image thereof is swept sideways across the face 28 of a vidicon or storage type camera tube 29 by a deflector 25 so that at one instant it is correctly registered thereon. Only at this instant will light emitted from a continuous source 33 and reflected by a dichroic 22 through a window 15 to the deflector 25 be reflected by a dichroic 26 so as to fall on a photodetector 37, which then triggers a xenon flash lamp 21, the light therefrom being such as to be transmitted via diohroic 22, the gate 11 and dichroic 26 to the face 28. It is arranged that the image sweep, and thus the flash from lamp 21, occur during the vertical blanking period, after the vertical retrace, and the gate 11 and deflector 25 are driven synchronously from a motor 18, the camera scanning also being synchronous therewith as both the motor 18 and deflection coil 31 are driven from the same A.C. source 19. The deflector 25 may be a mirror or refractor and may be rotated or merely moved by a cam mechanism sufficiently to compensate for the largest expected lateral error. The positions of the detector 37 and source 33 may be reversed. The light from lamp 21 will normally be visible light and must differ from the light provided by source 33. A shutter is provided for source 33 to prevent actuation of the lamp 21, e.g. by sprocket holes 13 when the film is moved during a television field period. The apparatus may be used for colour film if a suitable striped colour encoding filter is placed before the tube 29.
