Title: Pens having rotatable members
IPC: B05C17/00
Filed: 1979-03-27
Abstract: A pen has a rotatable member 7 in the shape of a torus held between the flanges of two bushes. This unit is mounted on a pen body 11, to project from the body 11 so that it can contact a surface to be painted. One part 14 of the body 11 supports a container 15 for paint. Paint issues from a nozzle 19 of the container 15 and makes contact with a bundle of bristles 16 housed in a second part 12 of the body 11. These bristles abut onto the rotatable member 7 to transfer the paint to the member and hence to the surface. In this way, a narrow line of paint may be applied to the surface to be painted. A holder 21 is attached to part 12 of the body 11. <IMAGE>

Title: Improvements in or relating to a turbine
IPC: F01D1/34
Filed: 1980-11-04
Abstract: A turbine 1 comprises a rotatably mounted rigid disc 2. Channels 4, equi-spaced around two pitch diameter circles extend through the disc 2. The axis of each channel lies at an angle to the plane of the disc, but not perpendicularly to the plane of the disc, and in a plane which is both perpendicular to the plane of the disc and tangential to the pitch diameter circle at a point where the axis of the hole 4 crosses the pitch diameter circle. The channels may be extended by tubes 7, which may be straight or curved. When the disc 2 is placed in a flow of fluid, e.g. water, the fluid passes through the channels 4 and the disc 2 rotates. In an alternative embodiment, the tubes lie between two coaxial radially spaced annular members, the inner annular member being attached to a central boss by three inclined arms. <IMAGE>

Patent GB-2073382-A (GB)
Title: Method of compensation for target location changes when firing ballistic missiles
IPC: F41G7/00
Filed: 1981-04-03
Abstract: Changes in the location of targets when firing ballistic missiles from firing devices aligned with respect to a particular target position can be compensated for without the need to realign the firing devices by establishing trajectory correction values which take into account the relation between the firing direction of the firing device and the expected position of the target when a missile fired in the firing direction will reach the position the firing direction was set for the missile to reach. These correction values are introduced before or at firing into an electronic storage means of the missile and after a predetermined time of flight cause the trajectory of the missile to be altered so that it is redirected towards the target's expected position by release of signals from the electronic storage means to trajectory adjusting means of the missile, such as fins, auxiliary rockets or jet-deflecting devices.
Patent GB-2076127-A (GB)
Title: Thermostatically controlled mixing valves for hot and cold water
IPC: G05D23/13
Filed: 1981-05-20
Abstract: The mixing valve controls the mixed temperature by means of a stainless bimetallic thermostatic spiral 146 which acts on a rotary slider 147 to affect the inflow of cold and hot water for the purpose of temperature control. The controlling and shut-off actions occur in a volume control cartridge 104 and in a separate temperature control cartridge 131. The volume control cartridge 104 comprises two packets each consisting of two relatively rotatable ceramic discs 121, 122 and 121', 122'. The cold water and the mixed water are controlled simultaneously by relative rotation of the ceramic discs. Approximately 90% of the housing wall is immersed in cold water. <IMAGE>
Patent GB-2077562-A (GB)
Title: Harvesting machines
IPC: A01D57/20
Filed: 1981-06-05
Abstract: A harvesting machine is provided with a reversible conveyor (5) which is mounted below the harvested crop discharge means and is arranged to convey the harvested material transversely to the direction of travel of the machine to discharge it at one end or the other of the conveyor arrangement. The conveyor has one discharge end that is outboard of one wheel and an opposite discharge end that is inboard of the other wheel. By operating the machine with the conveyor arrangement discharging material at one end during one operative run of the machine, and at the opposite end during the next run in the same direction, two closely adjacent swaths are formed which may be picked-up later in a single operation. The close spacing of the swaths is enhanced by mounting the conveyor arrangement for bodily movement in its conveying direction whereby the operative positions of the two discharge ends can be effectively brought closer together.   <IMAGE>
Patent GB-2100008-A (GB)
Title: Testing the matching of the deviations of frequency or phase modulated carriers
Inventor: SUSANS DONALD ERNEST DR
IPC: G01R23/00
Filed: 1981-06-09
Abstract: To test the matching of two frequency or phase modulated signals with different carrier frequencies the combined signal is applied to a non- linear device (9) which provides a difference frequency signal. This is selected by a bandpass filter (10), limited (11) and demodulated (12). The resultant is displayed on an oscilloscope. As a reference signal for the oscilloscope one of the two modulated signals is filtered out (4) and demodulated (6). If the signals are perfectly matched there will be no output from the measurement chain (9 to 13) and departures from this are manifested in different ways on the oscilloscope. The signals can be two stereo sound channels of a TV broadcast. <IMAGE>

Patent GB-2110888-A (GB)
Title: Oil filled electric cable system
Inventor: HOLDUP HENRY WILLIAM
IPC: H02G15/24
Filed: 1982-05-11
Abstract: In an oil-filled electric cable system, a joint between two cables includes an insulator 11 formed with a channel 18 extending to a region adjacent the jointed ends of the cable conductors and serving to facilitate initial impregnation of the joint insulation at that region. Oil feed to the cable in service of the cable system is not carried out through this channel, but is instead carried out directly into the space below the sheath 3 of each cable, for example through a lead 19 extending through the joint casing and into a closure 6 applied to the end of the cable sheath within the joint. Cable conductor 1 is mechanically and electrically connected to a joint ferrule 4 which also closes the end of the oil duct in the conductor. This ensures that little or no oil flows through the joint insulation in service of the system so avoiding weakness in the insulation caused e.g. by conducting particles. <IMAGE>
