Patent GB-2063806-A (GB)
Title: Improvements in and relating to sailing craft
IPC: B63H9/06
Filed: 1980-11-24
Abstract: In a sailing craft, particularly a yacht, having a hull (2) and a rig which includes a mast (8), a boom (18) and a sail (24), a permanent or sustained bend is induced into the portion (10) of the mast (8) above the hull by a pair of ties (20, 22), while the lower extent (12) of the mast is pivotally mounted in a bearing arrangement (14, 16) in the hull (2) such that the centreline of said arrangement, about which the mast (8) pivots, when extended above the hull, passes substantially through the centre of gravity (G) of the rig. The ties (20, 22) are such as to retain the mast (8) in a rigid bent condition, thus obviating the need for supplementary rigging, while the angled nature of the pivotal mounting of the rig provides a degree of mechanical and dynamic balance thereto which reduces the forces necessary to control movement of the craft. <IMAGE>

Abstract: A brush making machine (1) Fig. 3, has a carrier (7) provided with at least one brush body clamping means (5) with processing stations (11,8) arranged around the carrier including at least one filling device (11) for the brushes (4). The carrier (7) is rotatable about a transport axis (6), enabling the brushes (4) to be moved between processing stations, and about a pivot axis (S) eg by rotation of mounting 12 on bolt 20, which enables the bristles to be arranged in an inclined manner on the filling face (14) of the brush (4). Feeding of brush bodies to magazine (8) at different orientations about axis S may be effected through flexible tube 33, Fig. 6. <IMAGE>
Patent GB-2070872-A (GB)
Title: Receiver tuning arrangement
IPC: H03J1/00
Filed: 1981-01-28
Abstract: In a receiver having an automatic channel selecting function determined as the result of a comparison at 7, Fig. 1 of the field strength of a received signal with a reference 9, a tuned circuit 21 is coupled to an antenna input stage and is controlled so that its tuning frequency may be accorded with a selected frequency. Closing SW3 provides automatic channel selection by a microprocessor 12 which controls a divider 13 of a PLL 11 until comparator 7 indicates a received signal of sufficient strength. If the received signal becomes lower than the reference 9 the receiving frequency is automatically switched to another frequency. The microprocessor 12 also switches the input tuned circuit 21 by D1 to keep the sensitivity of the receiver constant and suppress fluctuation of automatic channel selecting performance. Data corresponding to desired frequencies may be read out of a read only memory in microprocessor 12 by operation of SW1 or SW2 so as to control the divider 13 of the PLL 11. <IMAGE>

Patent GB-2107148-A (GB)
Title: Distinguishing signals from noise
Inventor: GODDARD GRAHAM CLIVE
IPC: G01S13/524
Filed: 1981-03-20
Abstract: A signal receiver, for use on a Doppler radar system for example, disciminates between coherent received signals and background or other noise, on the basis only of the phase of the input signal, rather than its amplitude. The received signal is supplied via a hard limiter to a frequency disciminator, which will give a steady output when a coherent signal (i.e. of regular frequency) is received and a noisy output when the input is more random. A d.c. blocking filter reduces any such steady output to approximately zero, and a window detector provides a logic 1 level when the amplitude of the filter output lies within a small band centred on zero. Thus when a coherent signal is present the logic 1 level will persist for some time, and this condition is detected by a video integrator and threshold detector. Doppler information may be extracted by sampling the frequency discriminator output when a coherent signal is detected. A further window detector, responsive to the discriminator output may be used to prevent response to certain frequencies. <IMAGE>

Title: Improvements Relating to Hot- box Signalling Devices
IPC: G08B17/04
Filed: 1981-08-04
Abstract: A hot-box signalling device for indicating the presence of an overheated bearing in a vehicle such as a rail car includes means defining a closed compartment containing a fluid and pressure-sensitive means communicating with said compartment. The compartment is arranged in thermal communication with the bearing of the vehicle so that an increase in the temperature of the bearing causes an increase in the pressure exerted by the fluid. The pressure-sensitive means is adapted to produce a signal when the pressure exerted by the fluid exceeds a predetermined threshold representing an over-temperature condition in the bearing. Preferably, the pressure- sensitive means takes the form of a plug 24 normally closing an opening in the compartment, and a marker material 23, the plug and marker material being expelled when the pressure in the compartment reaches said predetermined threshold. Provision may be made to compensate for ambient temperature variations. The invention also provides a system for detecting the signal produced by the hot-box signalling device or by a tyre deflation signalling device (for use in a truck). <IMAGE>

Patent GB-2106306-A (GB)
Title: Improvements in electric cables and installations
Inventor: BALL EDMUND HUGH
IPC: H01B7/26
Filed: 1982-07-20
Abstract: A single-core electrical power cable for use at 400 kV for example has a relatively high-resistance inner shield located between and insulated from the central core of the cable and its low resistance metallic outer sheath. The inner shield is kept continuous throughout the cable run of installations where, for avoidance of currents circulating in the cable sheath, the sheath continuity is broken at spaced-apart locations. By virtue of such continuity, the inner shield provides a continuous path for surges developed in the cable as the result of lightning strikes or switching operations thereby preventing the development of corresponding high transient overvoltages at the outer cable sheath and particularly at the discontinuities therein. It is thus possible to dispense with the surge voltage limiters previously required to be coupled to the outer cable sheath at intermediate positions of cross-bonded systems.

Title: Optical display with excimer fluorescence
Inventor: NIGHAN WILLIAM LEO
IPC: H01J17/20
Filed: 1982-11-03
Abstract: A gas discharge display device, e.g. matrix or 7-segment, contains one or more gas species which react under the discharge to form excited molecules (excimers) which emit radiation as they decay. The radiation may be visible or in the UV, usable with a phosphor. The most efficient systems are mixtures of rare gases and halogen at pressure approaching 1 atmosphere, e.g. 20% Xe, 0.1% Cl2, remainder Ne. The gas space is 100 ???m deep between MgO electron- emissive coatings on 25 ???m glass dielectric layers over the crossed electrodes: at a total pressure of 2/3 atmosphere, pulses of 250 ns duration, repeated at 100 KHz, of the order of 500 V cause the formation firstly of XeCl*, followed by Xe2Cl* which dissociates with the emission of intense blue-green radiation (peak 226); making negligible the XeCl* peak (222) in the UV and the Ne peak (224) in the orange. Buffers other than Ne may be used, Cl may be added as HCl or CCl4 etc. Other excimers radiating in the visible are XeO*, KrO*, ArO*, Xe<2>Br*, XeF*; with the last, F may be added as F2 or NF3. <IMAGE>
