Abstract: 1,203,025. Railway systems; electric railways; air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 6 Sept., 1967 [6 Sept., 1966], No. 39891/66. Headings B7L and B7K. A gas-cushion vehicle having a body 1, Fig. 3, is supported for movement along a track 3, 4 and is driven by a linear-induction motor comprising stator structures 10 movably carried by the body 1 and co-operating with an aluminium rail 4b of the track portion 4, the stator structures 10 being adjustable in position relative to the vehicle body and the rail, as the vehicle moves over undulating track, in a direction across the face of the rail. As shown the body is supported by gas cushions 2 having flexible walls 6 and a peripheral slotted base 5, the cushions being supplied with air under, pressure from the vehicle by pipes 9. The stator structures 10 are carried by a yoke 11 pivoted at 12 to a cross-member 13 supported from the body by tension springs 14 and forming the bottom of an air chamber 16 having a flexible wall 15 and supplied with air under pressure by a pipe 16<SP>1</SP>. The member 13 is pivoted at 21 to the end of a rod 19 of a double acting piston 18 in a cylinder 17 carried by the body 1. The cylinder 17 is connected by pipes 26. 28 with a two-position valve 27 in turn connected by pipes 29, 31 with a cylinder 22 within a cushion 2. The cylinder 22 has a double acting piston 23 having a rose 24 pivotally connected at 25 to the base 5 of the cushion 2. The cylinders on both sides of the pistons and the pipes are filled with hydraulic fluid and when the cushions are to be supplied with compressed air the valve 27 is positioned to connect the pipes 26, 28 together and the pipes 29, 31 together. Air is then supplied to the cushions 2 to raise the body and thereafter air is supplied to the chamber 16 and the valve 27 moved, manually or automatically so that the pipes are connected as shown. As the vehicle is moved over an undulation via the track the cushions 2 are flexed to move the members 5 towards the body which at this time does not move relative to the rail 4b. Consequently the piston 23 is moved upwardly to cause upward movement of the piston 18 and thus upward compensating movement of the stator structures 10. In another embodiment both cushions are provided with hydraulic piston and cylinder systems. The vehicle may be guided by additional air cushions and the stators may co-operate with horizontal rail portions and be adjusted both vertically and horizontally.

Title: Improvements in and relating to machines having parts located by hydrostatic bearings
IPC: B23Q1/38
Filed: 1962-10-23
Abstract: 1,073,981. Machine tool slides; spindle mountings. PRODUCTION ENGINEERING RESEARCH ASSOCIATION OF GREAT BRITAIN, and G. P. KEARNEY. Jan. 23, 1964 [Oct. 23, 1962], No. 40161/62. Heading B3B. [Also in Division F2] A machine has a part which is movable and/or subjected to a load which changes in position and/or value and/ or direction and is located by hydrostatic fluid bearings, some of which are master bearings which directly respond to any tendencies of the machine-part to depart from its correct location and others of which are slave bearings which respond to the thrust demanded on the master bearings; all of the bearings however constitute a stable determinate system in which the load is shared between them. A machine tool way 11 and a pad 12 have pressurized fluid therebetween. The fluid from a main supply 16 is passed to a pressure-pocket 13 in the pad 12, via a valve 18 and to a probe-pocket 14 in the pad via an hydraulic resistance 17. The valve 18 is subjected to pressures acting on its opposite ends, one of the pressures being a reference pressure and the other the pressure in the probe-pocket 14 which depends on the escape gap between a probe surface 15 and the way 11. The arrangement acts to restore the probe escape gap to a fixed value. The reference pressure may be maintained constant by means of hydraulic resistances 21, 22 which are in series and have one end connected to the supply 16 and the other end of the series constituting a leak. In modifications, an extension of a pad (12), Fig. 2 (not shown), carries a probe-pocket (14) which coacts with a surface of the way (11), this surface facing an opposite direction to the surface of the way (11) which coacts with the pad (12); a pair of oppositely-facing probepockets (14a, 14b), Fig. 3 (not shown), may be provided; hydraulic resistances are used to cause a differential pressure; and an electricallyactuated valve supplied with electrical signals through an amplifier from an electro-mechanical transducer, for example, may replace the hydraulically-actuated valve.

Abstract: 1,027,168. Signal generators. L. ROHDE, and H. SCHWARZ, [trading as ROHDE & SCHWARZ]. Nov. 8, 1962 [Nov. 14, 1961], No. 42252/62. Headings H3A and H3F. In a variable frequency signal generator in which the output frequency is equal to the sum or difference of a harmonic of a fixed standard frequency and a continuously variable frequency covering the range between harmonics, obtained from an internal oscillator, the internal oscillator may be replaced by an interval generator having the same frequency range which supplies an output frequency equal to the sum or difference of the interval oscillator frequency divided by a given factor and a further standard frequency adjustable in steps. The signal generator may operate on either the frequency synthesis or frequency analysis method. In the frequency analysis method shown in Fig. 4, the oscillator 28 supplies the signal generator output frequency FA and also provides one output to a mixer 24 which is also supplied with the output of a turnable filter 23 which selects a harmonic of a source 21 operating at a standard frequency FN1. The difference frequency from the mixer is selected by filter 25 and compared in phase comparator 26, when the switch is in position A, with the output of an interval oscillator 101 to provide a signal for the control via variable reactance element 27 of oscillator 28. When a more accurate frequency setting is required the switch is moved to position B and the interval oscillator 1 is replaced by interval generator IG1. This comprises an oscillator 28<SP>1</SP> controlled in a similar manner to oscillator 28 by a source of standard frequency FN2, being the frequency FN1 of source 21 divided by N and the output of interval oscillator 101 divided in unit 31 by a factor N. The output of oscillator 28<SP>1</SP> provides the comparison frequency for application to phase comparator 26. Where the frequency of source 21 is e.g. 1 Mc/s., the interval oscillator range is 0-1 Mc/s. and factor N = 10, the number of megacycles is set by turnable filter 23, the number of 100 kc/s. is set by filter 23<SP>1</SP> and the remaining figures are read from the scale of oscillator 101.
