Filed: 1974-01-31
Abstract: 1417673 Antiskid braking systems GENERAL MOTORS CORP 31 Jan 1974 [19 March 1973] 04525/74 Heading F2F An antiskid braking system comprises means to provide a signal representing speed of a braked wheel, a differentiator 26 responsive to the speed signal to produce a signal representing wheel acceleration, means arranged to provide a vehicle deceleration reference signal including means connected to the differentiator and responsive to the maximum positive wheel acceleration signal during each cycle to provide a continuously variable vehicle deceleration estimate signal comprising a portion of the reference signal for each succeeding cycle, an integrator responsive to the acceleration signal and the deceleration reference signal to produce a velocity error signal representing the difference between wheel speed and an estimated vehicle speed and means responsive to the velocity error signal to produce an output signal causing brake release when the error signal exceeds a predetermined threshold value and causing reapplication of the brakes when the error signal drops below a second lower threshold value. Tachogenerators 12, 12<SP>1</SP> provide wheel speed signals which are fed to frequency/voltage converters 16, 16<SP>1</SP> and thence to a maximum speed selector 20. The differentiator circuit 26 provides outputs on lines 28, 30, 32 and an acceleration follower circuit 46 senses the signal on line 30 and provides an output on line 48 to a release integrator 34 in line 28 having an output connected to a release comparator 38 connected in turn to a solenoid driver 42 operating the brake release valve 68. The wheel speed signal on the output line 22 is connected via a variable threshold-with-speed circuit 44 to comparator 38. An acceleration switch 50 sensitive to the acceleration signal on line 32 contributes to the signal on line 48 a pulse representing 0À58 g. when the positive wheel acceleration exceeds a predetermined value (2À3 g.) during each brake release. A minimum g.-level circuit 52 continuously supplies a small signal to line 48 representing a value of about 0À1 g. A delayed g.-level circuit 54 adds to the signal line 48 a contribution representing 1À16 g. a delayed time after brake application the time constant being 0À6 second. The air brake system includes a compressed air source 56 connected through a regulator valve 60, operated by a pedal 64, and solenoid valve 68 having an exhaust 72 to a relay valve 78 connecting a source 80 of compressed air to an actuator 88. In operation integrator 34 compares the deceleration signal on line 28 with the reference signal on line 48 and integrates the difference, the output on line 36 representing the velocity error which is compared with the threshold from circuit 44 to obtain a signal to release or apply the brake.

Title: An improved method for the production of hollow moulded articles from polystyrol
IPC: B29C48/90
Filed: 1935-02-12
Abstract: 445,974. Moulding polystyrol tubes. SIEMENS - SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Feb. 12, 1935, No. 4555. Convention date, Feb. 13, 1934. [Class 87 (ii)] In moulding continuous tubular lengths of polystyrol so as to give reduced brittleness and increased flexibility, a tube 13 of crosssection smaller than that desired is extruded and gradually expanded while still thermoplastic by means of internal fluid pressure. It may then, if necessary, be cooled. A tube extrusion press 12 may co-operate with a moulding conduit 16 having a gradually increasing cross-section. Compressed air may be introduced by a pipe 14 so as to expand the tube 13 against the conduit 16. An intermediate tube 15, which may be cooled, may support the tube 13 between the press and the conduit. Alternatively, the tube 13 may be allowed to expand, unconfined, between the press and the conduit and the initial cross-section of the conduit accordingly enlarged. A cooling tube 17 may be provided at the outlet end of the conduit. The tube 13 may be corrugated or indented by the conduit 16 or by separate devices, and it may be fed forward by caterpillar devices. The tubes 15, 16 may be lubricated. The Specification as open to inspection under Sect. 91 comprises also the use of substances similar to polystyrol in the polyvinyl or other hydrocarbon groups and also a method wherein a preformed body of polystyrol or like substance is placed on a blowing nozzle within a hollow mould and is expanded by compressed air into contact with the mould. The body may be heated prior to blowing or by using hot compressed air. A partial vacuum may be produced in the mould. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the treatment of tows of textile material
Inventor: MARSH ARTHUR EDWARD LEE
IPC: D01D10/04
Filed: 1952-02-21
Abstract: A continuous tow of artificial filaments is treated as described in the parent Specification and one or more streams of gas are introduced into the treating bath below the accumulated tow so that bubbles of the gas rise through the liquid and through the mass of convolutions of the tow.  Air bubbles may be introduced into the bath by a system of interconnected perforated tubes arranged below one of the supports described in the parent Specification and connected to a compressed air supply. Alternatively the system of tubes may form the support for the tow.  The movement of the gas bubbles through the liquid improves the buoyancy of the tow, in some cases to such an extent that it is possible to dispense with a support for the tow and to support the tow in the liquid, and at the same time maintain a free liquid space below the tow, by the air bubbles alone.  In addition the gas bubbles serve to circulate the bath and ensure a more even treatment of the tow, thus rendering it unnecessary to provide additional means for circulating the bath liquid such as that shown in Fig. 1 of the parent Specification.ALSO:In the apparatus for the treatment of a continuous tow of textile material as described in the parent Specification means are provided for introducing one or more streams of gas into the treating bath below the accumulated tow so that bubbles of the gas rise through the liquid and through the mass of convolutions of the tow.

Abstract: 234,875. Higgins, C. F. Nov. 24, 1924. Separating by gravity.-The constituents of a mixture, such as oil and water, are separated during passage through a tank divided into compartments so that liquid flowing upwards in one compartment passes over a weir into the next in which the flow is downwards and the lighter liquid separates on the surface. The tank B is divided lengthwise by partitions D. E, and laterally by weirs F<1>, F<2>, F<3>. The mixture enters the compartment H through an inlet G at the bottom and flows over the weir F<1> into the compartment J. Oil separate on the surface and is directed by a guide plate L to an outlet K the area and depth of which can be regulated, the rest of the liquid flowing into a channel formed at the bottom by a plate N, which directs it through an orifice 0' into the next upwardflow compartment P. The later downwardflow compartments R, V are provided with outlets K to which the lighter liquid is directed by guide plates S, W, and the heavier liquid is finally discharged over a weir X. The sump into which the lighter liquid enters through the outlets K is provided with outlets B<1>, C<1> at different levels so that a further separation can take place there. Steam admitted through a nozzle D<1> and rising in a pipe G' draws liquid from the compartment J and causes it to pass again over the weir F'. Liquid may be withdrawn in this manner from any of the downwardflow compartments and re-circulated over one or more of the weirs.

Filed: 1940-03-16
Abstract: 538,813. Treating artificial yarns and threads. CARBIDE & CARBON CHEMICALS CORPORATION. March 16, 1940, No. 4914. Convention date, April 22, 1939. [Class 2 (ii)] The elongation of stretched yarn or thread made from vinyl resins is set or increased by passing the fibres under tension through a heated zone, so that the yarn is raised to a temperature below its softening point for a sufficient time to set the stretch so that there is no appreciable contraction when the tension is released. Apparatus is shown by which the yarn is set continuously as it is passed from one bobbin to another, and it is at the same time flexed to give it a soft feel. The stretched, but otherwise untreated yarn 10 may be supplied direct from the stretching apparatus, or, as shown, from a wound bobbin 11 frictionally driven by a roller 12 so that the yarn is fed forward at a constant rate. It passes round a roller 13 and round flexing rollers 14 of small diameter making a suitable number of laps, and is then wound upon a bobbin 15 with a traversing mechanism 17. The bobbin 15 is frictionally driven by the roller 16 which runs at the same peripheral speed as the rollers 12, 13. The roller 13 is partly submerged in a liquid, such as water, in a tank 18 maintained at the desired setting temperature. The Specification includes description showing the effect upon a vinyl resin yarn spun from a conjoint polymer of vinyl chloride with vinyl acetate of different periods of exposure to the setting bath. The differing periods are obtained by varying the number of laps round the rollers 13, 14. Specifications 518,555 and 518,710 are referred to.
