Patent GB-735412-A (GB)
Title: Apparatus for the driving control of a motor vehicle
Filed: 1953-10-02
Abstract: 735,412. Change-speed control. DAIMLER-BENZ AKT.-GES. Oct. 2, 1953 [Oct. 2, 1952], No. 27088/53. Addition to 689,125, [Group XXXI]. Class 80 (2). [Also in Groups XXIX and XXXI] Means for automatically controlling the change-speed gearing, engine throttle, and brakes of a motor vehicle as in the parent Specification is subject also to control by means sensitive to acceleration and deceleration of the vehicle. A piston control valve b 1  controls the passage of pressure fluid through conduits 32, 33, a change-over valve C which permits operation with engine braking, conduits 81, 83 and an engine-speed limiting valve D to a servomotor G for controlling the change-speed gearing which is preferably gradually variable. The valves C, D differ from the corresponding valves in the parent Specification in that the valve C is positioned according to whether the engine is driving or being driven by the pressure from a pump N between the driving and driven members n 1 , n 2  of a hydraulic coupling, and the valve D is actuated directly by an engine-driven centrifugal governor K. The valve b 1  also controls conduits 34 ... 37 leading through the valve C to a servomotor E for controlling the engine throttle F, and a conduit 31 leading to the vehicle brakes. The valve b 1  is connected by a lever 1 to a centrifugal governor I responsive to vehicle speed and to a pedal A and hand-lever A1 by either of which the required speed is set. A sleeve b 2  surrounding the valve b 1  is slidable by an inertia weight m 1  in such manner that when the valve b 1  is reset for a different speed the sleeve is moved in the same direction by the consequent acceleration or deceleration to cause the acceleration or deceleration to be proportional to the difference between the required speed and the instantaneous speed. The control apparatus may be hydraulically or pneumatically operated, or electrically operated utilizing contacts sliding over resistances.

Title: Improvements in apparatus for controlling the application of power
IPC: B60T13/18
Filed: 1939-10-04
Abstract: 537,373. Fluid-pressure servomotor controlsystems. ROCKWELL E. A. Oct. 4, 1939. No. 27189. Convention date, Nov. 19, 1938. [Class 135] [Also in Group XXXIV] A valve device for the control of hydraulic power apparatus suitable for operating motor vehicle brakes comprises a tubular valve member adapted to be closed at one end and to be moved axially by an exhaust valve to unseat a supply valve provided on the peripheral surface of the tubular member whereby pressure liquid is supplied through the tubular member to the operating cylinder. The valve device may be connected between two parts of a link extending from the pedal to mechanical connections by which the brake &c. is operated. The casing 17 of the control valve is mounted on a bracket 12 to which is secured a rod 13 connected to the rock shaft 72 which is operated by the piston rod 66 of the hydraulic cylinder 50 pivoted at 55 on the chassis frame 4. The shaft 72 carries levers 73, 74 connected to the brakes. The forked end 8 of a rod 7 extending to the pedal 5 is connected to the bracket 12 by a link 10 and a lever 11 which operates the valves within the casing 17. The hydraulic pressure supply, exhaust and the cylinder 50 are connected respectively to passages 34, 35, 36, Fig. 4, in the casing. A slidable tubular valve member 31 is provided with a supply valve 41 which is normally seated at 40 by a spring 29 which extends into the member 31 and seats on a shoulder therein. An exhaust valve 25 operated by the lever 11 through a rod 20 is normally unseated from the end of the member 31 as shown by a spring 27 extending through that member. The cylinder 50 is thus normally open to exhaust passage 35, through the member 31. When the pedal is depressed the valve 25 seats on the end of member 31 to close the exhaust and moves this member to unseat the supply valve 41 permitting the supply of pressure liquid to the cylinder 50 through passage 34, holes 43 in member 31, and through member 31 to passage 36. When the pressure in the cylinder acting on the member 31 and on the valve 25 is sufficient to overcome the pedal pressure the valve 41 is reclosed. The pressure can thus be graduated in accordance with the pedal pressure. Graduated release is similarly obtained upon decreasing the pedal pressure. Pressure can also be applied to the brakes mechanically through the rods 7, 13 and the valve. The pressure liquid is supplied by pipe 84 from an accumulator 78 the pressure in which is maintained by a gear pump driven by an electric motor 83 as described in Specifications 473,568 and 490,450. The exhaust liquid returns to the accumulator by pipe 77.

Title: Thermoplastic films and method and apparatus for obtaining the same
IPC: B29C48/08
Filed: 1961-07-31
Abstract: In a method for producing sheet film of thermo plastic material the cumulative effect of straight line gauge variation, due usually to small defects in the extrusion die lips, on the appearance of a roll of the film is overcome by introducing a controlled gauge variation over the film in such a manner as to avoid the magnification <PICT:0934773/IV(a)/1> effect.  In the apparatus illustrated molten film 5 is discharged downwardly from die lips 3, 4 between hollow chill roll 11, cooled by refrigerated liquid entering hollow shaft 11a and leaving hollow shaft 11b, and water roll 12 in trough 21 provided with weir 22 and overflow cup 23 having discharge connection 24. Nozzle 34 directs a stream of water downwardly against sheet 5 at a pressure of from 1/2 to 10 p.s.i.  To produce a gauge variation greater than the average gauge the stream is at least 3 DEG C. below the water bath temperature and is directed 1/4 inch above the water bath level.  For a smaller gauge variation the stream is at least 3 DEG C. above the water bath temperature and is directed 1/4 inch below the water bath level.  Nozzle 34 is reciprocated by motor 39 driving block 33 reversibly on rods 37, 38 thus generating a sine-wave gauge variation which masks any straight-line gauge variation.  Specification 914,100 is referred to.
