Patent GB-2052034-A (GB)
Title: Heating and Cooling Systems Including Heat Pumps
IPC: F25B13/00
Filed: 1979-06-11
Abstract: Heat is extracted from the environment (typically a house or building) and, by a heat pump (10, 12, 14), is imparted to the earth or a volume of water the temperature of which is thereby increased. However, since the mass of the earth or the volume of the water concerned is so great the temperature rise is very small. In a reverse mode of operation, heat from the earth or volume of water is extracted by the heat pump installation and injected into the environment (house or building) so that the temperature of the latter is raised and as a consequence the temperature of the earth or volume of water is lowered. The heat is imparted to or from the ground (or water) by a coil (10) embedded therein at a depth of at least one metre with the axis of the coil being substantially vertical or horizontal. The system may be reversible. <IMAGE>

Patent GB-2068110-A (GB)
Title: Secure optical communication system
IPC: G02B6/24
Filed: 1980-01-22
Abstract: The intelligence on an optical communication system is made secure by launching an intelligence modulated optical beam into the input end of an optical waveguide (1) at a small angle with respect to the longitudinal axis of the waveguide, and launching a masking signal modulated optical beam into the input end of the waveguide at a large angle (r1) with respect to the axis. At the output end of the waveguide, only the intelligence modulated optical beam is transmitted to an optical detector 13. The masking signal is blocked by a member 3 having an aperture so located as to pass the intelligence modulated beam. This prevents an intruder from separating the intelligence signal from the masking signal when observing the waveguide radially. <IMAGE>

Title: Improvements in and relating to feed assemblies
IPC: A01C9/02
Filed: 1980-02-01
Abstract: Existing potato planters are constrained to operate at relatively low planting rates in order to ensure adequate inspection and correction of the tuber distribution in the feed assembly of the machine prior to planting. By contrast, the present invention provides a relatively high-throughput feed assembly comprising two slow-moving feed belts 10, 11 (Fig. 1) which laterally convey rows of tubers from a supply hopper 13 and over an inspection/correction area to downwardly- inclined cross-transfer belts 16, 17. These latter discharge the tubers at planting locations 19, 20 (Fig. 2). Having the tubers closely packed on the two slowly moving feed belts maximises the available inspection and correction time whilst the row by row discharge on to the cross-transfer belts ensures a relatively high planting rate. <IMAGE>

Filed: 1980-03-17
Abstract: Digital simulation apparatus, e.g. a digital coastline generator, for simulating a terrain-representative display of the kind produced by a movable scanning-type display device, e.g. a radar display device, comprises a main store 12 for storing digital data representative, in Cartesian co-ordinate form, of terrain features such as contours and buildings in an area, known as the playing area, typically 256 nautical miles by 256 nautical miles. The data is divided into groups relating to contiguous zones each typically 2 nautical miles by 2 nautical miles. The apparatus further comprises means for producing a signal representative of the current position of the display device in the playing area, means for producing successive signals representative of successive segments of scan of the display device, and means 14 responsive to these signals to select from the main store those groups of data corresponding to zones intersected by the current scan segment. The selected groups of data are applied to co-ordinate conversion means 16 which converts them into polar co-ordinate form, in which form they are then used to generate the simulated display. The selection process greatly reduces the computational burden of the co-ordinate conversion means. <IMAGE>

Title: Friction pad guide device for disc brake
IPC: F16D65/095
Filed: 1980-08-20
Abstract: A friction pad guide device for a disc brake, in which the liners (13, 14) of friction pads are bent perpendicularly at both side ends toward the back surface sides to form vertically bent portions (13a, 13b, 14a, 14b), which are slidably engaged with inner vertical guide surfaces (9a, 10a, 11a, 12a) respectively extending elevationally of a torque retainer, and the upper portions of which are bent perpendicularly toward the opposite side directions to form laterally bent portions (13c, 13d, 14c, 14d), which are slidably engaged with the inner lateral guide surfaces (9b, 10b, 11b, 12b), respectively of the torque retainer, thereby slidably suspending the friction pads from the torque retainers. The length (L) of the vertically bent portions (13a, 13b, 14a, 14b) is formed to be greater than the thickness (l) of the liners (13, 14), whereby damage to the guide is prevented by the increased sliding area. If the configuration is such that the guide portion ends at the disc portion, the liners (13, 14) are prevented from dropping from the guide when the friction pads are worn out. Further, it becomes unnecessary to finish the side end surfaces of the disc in the guide after casting the torque retainer.
