Title: Onmidirectional doppler navigation system
IPC: G01S1/40
Filed: 1972-12-06
Abstract: 1402285 Radio navigation INTERNATIONAL STANDARD ELECTRIC CORP 6 Dec 1972 [7 Dec 1971] 56303/72 Heading H4D In a Doppler V.O.R. navigation system a frequency f 0 , modulated by device 7, is transmitted from antenna 12, the system being characterized in that at least two sidebands, e.g. f 0  + f 1 , f 0  + f 2  are transmitted simultaneously from antennas 11(1) ... 11(n) the two sidebands being switched to the antennas so that they are transmitted in opposite senses of rotation. A clock 10 synchronizes the switching devices 13, 9 which feed hybrids 8(1) ... 8(n). Generators 1, 2, 3 supply the frequencies f 0 , f 1 , f 2  respectively and generators 4, 5 produce the sidebands. Sidebands f 0 -f 1 , f 0 -f 2  may also be transmitted and the switching is then arranged so that these sidebands are switched to the antenna at the location opposite to the antenna carrying the other corresponding sideband. In the receiver (Fig. 3, not shown) the phase difference between the sideband signals of opposite rotation is measured by device (30) to give azimuth indication. The phase difference between the signal at frequency f 0  and f 0  + f 1  or f 0  - f 1  is used to determine if the aircraft is approaching or receding from the antennas. The polarity of the azimuth indicator (31) is accordingly altered automatically to remove ambiguity.

Title: Straddle carriers
IPC: B62D33/067
Filed: 1973-12-20
Abstract: 1488810 Straddle carriers RUBERY OWEN MECHANICAL EQUIPMENT Ltd 19 Dec 1974 [20 Dec 1973] 59266/73 Heading B8H [Also in Division B7] The operator's cab 22 of a straddle carrier is movable from an upper position to a lower position (shown in phantom) in which it is available for access and servicing. The carrier may be controlled from the cab when the latter is in either of its positions. The cab is supported on a boom 27 which is pivoted to one of the front pillars 23 of the carrier and is lowered or raised by the extension and retraction of an hydraulic jack 31. Links 29 form a parallelogram linkage with the boom 27 so that the cab remains upright during its movement. When the cab is in its upper position, a pair of hydraulic locking units can lower locking plates which imprison cab plates 38 against plates 37 on the carrier structure. When the cab is in its upper position a switch 61 is closed to operate a relay 67<SP>1</SP> and thereby close contacts 67 to energize an indicator 98. Locking the cab in its upper position closes a further switch 95 (Figs. 4 and 6) which operates a relay 68<SP>1</SP> to close indicator contacts 68 and also to close contacts 73. The closed contacts 73 allow powered to be supplied to the normal drive and hoist circuits of the carrier then a can switch 64 is placed in the position shown in Fig. 6. When the cab is in its lower position, a switch 71 (Figs. 2 and 6) is closed and, via a relay 69<SP>1</SP>, energizes an indicator 100 and closes contacts 74 which are in parallel with the contacts 73. Thus the drive and hoist circuits of the carrier can only be operated from the cab when the latter is in its upper or its lower position. The carrier is steered by a pair of double acting piston and cylinder units (118, 123), Fig. 7 (not shown), included in an hydraulic circuit which has a control valve (106) and associated pump both controlled by a steering wheel in the cab. To raise or lower the cab, the switch 64 is moved to a position in which contacts 63 and 76 are bridged. This in turn operates solenoid valves 80 and 82 to disconnect the steering piston and cylinder units from the hydraulic pressure supply and to connect instead the cab jack 31. Operation of the control valve (106) then raises or lowers the cab. So long as the "down" switch 71 is not closed, the locking assemblies 39 will be operated by a solenoid valve 75 when the switch 64 is returned to its illustrated position. In an emergency, a solenoid valve 89 may be actuated from either inside or outside the cab. The valve opens a by-pass line to connect one end of the cab jack cylinder to the other. The cab then falls under its own weight at a speed determined by a variable orifice in the by-pass. In modifications (not shown), the position of the cab when it is raised or lowered may be adjusted, the cab may be rotatable about a vertical axis to improve the operator's field of view, and the cab may be mounted at the rear of the carrier.

The thickness of the abrasive layer 4 is between approximately 0À3 mm. and 0À6 mm. The grain size of the abrasive particles is in the range 10-125 microns, the major proportion being between 20 and 40 microns. The abrasive layer contains approximately 65-75% by weight of abrasive material and approximately 35-25% by weight of binder. The abrasive material may be carborundum, corundum (Al 2 O 3 ), ground pumice, silicon carbide, zirconium sand (ZrO 2 ), powdered glass, quartz, chromic oxide or mixtures of these individual substances. The binders preferably consist of one or more thermosetting resins for example two-stage resins on a phenol basis or one-stage resins. The hardener binder of the abrasive layer 4 has a temperature resistance equivalent to the temperature resistance of the binder of the friction lining 3, and the minimum of the temperature resistance of the abrasive layer 4 is determined by the fact that less than approximately 7% of the binder disintegrates at a temperature of 500C. and no measurable disintegration fraction of binder can be determined at the operating temperature of the brake. The abrasive layer 4 is preferably applied to the friction lining after the latter has been pressed. The abrasive layer 4 cleans the coacting surface of the disc or drum when the brake shoe 1 is used for the first time, and grinds the surface smooth.

Abstract: 1325188 Automatic position control NIPPON SELFOC K K 30 Dec 1970 [30 Dec 1969] 61804/70 Heading G3R In a multiplex light transmission system in which a plurality of light beams, e.g. laser beams of different wavelengths, are transmitted over long distances through a succession of lenses spaced at single or double focal distances, a plurality of fibrous light guides, e.g. of glass, are provided at points where the beams are parallel to each other to detect and correct positional, deviations of the beams, e.g. due to temperature effects. Each light guide is converging, i.e. has a refractive index which decreases approximately parabolically in dependence on the distance from its axis, and deviation in the position of a beam applied to one of them, 701 Fig.8, is detected by unbalanced illumination of a four segment photosensitive ring 704 the signals from which cause controller 706 to adjust the position of lenses 702, 703 and the end of the light guide until the original position of the beam relative to the guide is restored. Then any deviation in the angle of incidence of the beam is detected by the unbalanced illumination of a further photo-sensitive ring 707 signals from which cause a controller 709 to tilt lenses 702, 703 and the end of the light guide, as shown dotted, until the original angle of incidence is restored. In a modification, Fig.7, a controller 633 (a) adjusts the position of the end of a light guide 621 in dependence on signals from a photosensitive detector 631 to restore the relative position of beam and light guide and (b) tilts the end of the light guide, to restore the angle of incidence, in dependence on the angle at which the beam emerges from the other end of the light guide as determined by photo-sensitive detector 637. Matching of beam sizes inside and outside the light guides by tapering the guide ends or using supplementary lenses is described.

Title: Data transmission method and apparatus
IPC: H04B7/005
Filed: 1978-09-19
Abstract: In a data transmission system in which a first station can call up a second so as to receive a data signal from the second station, the first station causes its receiver to accept the data signal only after a predetermined time VZ since the first station has sent a call-up signal to the second station. Thus the effects of mis-synchronisation of the first station receiver due to interference signals preceding the data signal, can be avoided and the synchronising word SY2 preceding the data signal can be much shorter than in known systems so saving transmission time. The synchronisation of the receiver is held in dependence on the enabling for data signal reception so that, during the latter, correct synchronisation is assured. <IMAGE>
