Title: Vehicle steering system

Filed: 1975-10-31
Abstract: 1519063 Power steering T R W Inc 31 Oct 1975 [6 Nov 1974] 45511/75 Heading B7H In a vehicle steering system comprising a steering control valve 14 manually operable to. direct fluid from a variable source 44 to a steering motor 20 via a metering device 18, a hydraulic system is provided which is responsive to the fluid pressure demand for steering by the metering mechanism to vary the fluid pressure output of the source to the metering device to effect steering. As shown in Fig. 1, actuation of control valve 14 causes fluid from conduit 72 to be ported to operating chamber 68 of motor 20 via metering device 18. Fluid discharged from chamber 78 is directed to a variable size size orifice 82 and to a flow compensator valve 30. The size or orifice 82 varies directly with the rate of rotation of the steering wheel 64. Thus the pressure signal through conduit 32 varies as a function of the size of orifice 82 and hence the compensator valve 30 varies the output of a variable swash plate pump via a motor chamber 100 according to the demand for steering fluid made by torque applied to steering wheel 64. The variable orifice 82 is preferably formed between the valve spool (152) Fig. 2A (not shown) and the valve housing and forms the subject of Specification 1,519,062. In a modification of the steering system the variable orifice (270) Fig. 5 (not shown) is provided on the pump side of metering device (18b). Alternatively, conduit means may conduct a relatively large fluid flow from the pump to the metering device (18a) Fig. 3 (not shown) and by means of constriction (200) conduct a relatively small flow to variable orifice (202).

A machine for forming a wall in the ground by excavating a trench and filling it with material to form the wall, comprises a box having side walls interconnected by transverse walls 3, 6, the latter dividing the box into a forwardly open front chamber housing. Trenching machinery, a rearwardly open rear chamber for receiving the material, and at least one intermediate chamber housing hydraulic rams 18 adapted to press against the erected part of the wall to move the machine forwardly. The trenching machinery, which may be an airlift pump but is preferably an endless belt device 14, is disposed in a box 11 housed in the front chamber for movement forwardly thereof by rams 12, the box 11 having step plates 13 and the fronts of these and of the box 11 having cutting edges for loosening the earth ahead of the machine. The rams 18 actuate a common pressure foot 19 to press against the last-formed section 20 of the wall to move the machine forwardly, machine being supported by wheels or rollers 16 on a track 17. A shallow trench which may have concrete walls 21 is first excavated along the line of the wall before the machine is used, and holes 24 may be bored in this trench to guide the machine. A thixotropic agent may be used to fill the holes 24 to lubricate the sides of the machine. Instead of the holes 24 a steel pile may be driven into the earth ahead of the machine to loosen the earth, Fig. 9 (not shown). If water is present one or more of the intermediate chambers may be flooded to counteract uplift. The box 11 may be dispensed with, the device 14 being mounted directly in the front chamber which is provided with the step plates 13 and which has front cutting edges, Fig. 8 (not shown). If the wall is curved the machine may be in parts interpivoted for movement about a vertical axis, Fig. 7 (not shown). The device 14 may be removable from the front chamber to allow access for the removal of obstacles such as large stones. The material used for the wall may be in the form of prefabricated members or material which sets after it is poured into the rear chamber.

Title: Stereoscopic display device

Filed: 1974-10-25
Abstract: 1448520 Polarization stereoscopy STANDARD TELEPHONES & CABLES Ltd 25 Oct 1974 46259/74 Heading G2J Stero images are displayed alternately and sequentially on a common surface e.g. CRT 10 or cinema screen and are separated for observation by right and left eyes 13, 14 by an optical system including fixed polarizers and one or more liquid crystal cells acting as electrically controllable optically active elements operable at the image alternation frequency.  In one embodiment Fig. 1a a linear polarizer 11 is placed in front of, or forms part of a CRT screen 20. In front of polarizer 11 is a twisted nematic liquid crystal cell 12 having a 90 degree twist and the display is observed through linearly polarizing spectacle elements 13, 14. In the absence of an electric field across cell 12 as in Fig. 1a, the cell is optically active and rotates the plane of polarization by 90 degrees; hence the display is seen only by the left eye 15. When an electric field is applied the optical activity of the cell 12 is destroyed so that the display is seen only by the right eye 16. The application of the electric field is synchronized with the presentation of alternate images at a rate such that persistence of vision gives the illusion of a 3-D image. Separate polarizers 11 and cells 12 may be provided for each eye. In another embodiment Fig. 2a CRT 20 is covered with linearly polarizing material 21 in front of which is birefringent #/4 plate 27 oriented with 21 so that a circular polarizer is formed. Between 21 and 27 is placed a 90 degree twisted nematic liquid crystal cell 22 with one of its alignment directions parallel to the plane of polarization of 21. When no field is applied Fig. 2a cell 22 reverses the handedness of the circularly polarized light; when a field is applied the original handedness is unchanged. The display is observed through spectacle elements 23, 24 which are lefthanded and right-handed respectively. Cells 12, 22 comprise a thin layer of a nematic liquid crystal medium (e.g. a mixture of cyanobiphenyl hydrocarbon derivatives) sandwiched between electroded glass plates whose inner surfaces are treated so that the molecules of the liquid crystal medium that are in contact with the surfaces are aligned at right angles to one another. Other liquid crystal devices (cholesteric or smectic) or combinations of them may be used.
