Title: Method for the transmission and projection of video images, in particular aerial photographs, with a reduced frequency in the image sequence
IPC: H04N7/00
Filed: 1981-05-06
Abstract: A method is provided for the transmission and reproduction of video scenes, particularly by aerial photography, in which there is reduced image frequency within a sequence of images and there is relative movement between a pick-up sensor and an object to be detected. The method consists in the production on the reproduction side of intermediate images by interpolation and/or extrapolation compatible with the reproduction system with respect to two transmitted images for each intermediate image, the introduction of the intermediate images into a transmitted sequence of images, and determining image point positions of the two transmitted images to be combined by interpolation or extrapolation by correlation of image point positions which are known for at least two object points situated in different vertical and horizontal coordinates within each of the two transmitted images. <IMAGE>

Title: Device for supplying current to a movable print head
IPC: H01R35/00
Filed: 1981-06-18
Abstract: To avoid the use of a single flexible plate cable, which supplies electricity to a moving print head carriage 20, and which because of its weight may tend to kink or impose a drag on the carriage a pair of cables 23, 23' are used. These need have only half the number of leads and so avoid the above disadvantages. <IMAGE>

Title: Fuel filter assembly and cartridge
IPC: B01D27/06
Filed: 1981-06-23
Abstract: A fuel filter assembly and cartridge (1) for filtering, coalescing and separating solids, liquids, and gases from a liquid fuel flow including a housing (4) adapted to receive a removable cartridge (40). The cartridge (40) is in the form of an annular member having an outer annular filtering section (51) to remove solids and an inner annular coalescing section (52) to cause emulsified liquids, e.g. water, to form readily removable droplets in the flow.

Title: Electronic ignition systems for internal combustion engines
Inventor: HAWKINS JOHN STUART
IPC: F02P3/045
Filed: 1981-11-26
Abstract: Electrical control signals for determining the generation of ignition pulses are derived by way of a fibre optic system in which a light beam is led from a light emitting device (20) to an actuating device such as a disc (10) or a vane (16) which rotates at a speed related to the prevailing engine speed. The light beam is arranged to be modulated by the actuator (10) or (16) in dependence upon engine speed and the number of engine cylinders before being led to a light receiver (24) which provides a trigger signal for controlling the generation of the ignition pulses. Preferably, the trigger signals are initiated at a fixed angle of advance in relation to the engine operating cycle, and a control voltage (42) is generated for delaying the initiation of ignition pulses for a duration determined in dependence upon the prevailing engine speed and a predetermined engine speed/advance characteristic. <IMAGE>

Title: Controlled rectifier bridge converter
Inventor: FINNY DAVID
IPC: H02M7/49
Filed: 1982-10-08

Title: Improvements in road cones or the like
Inventor: MILLS BARRY
IPC: E01F9/012
Filed: 1983-02-09
Abstract: A road cone which includes a closed ballast cavity in its base portion 2 is formed by dip-moulding from a flexible polyvinyl chloride. The bottom wall 2b of the base portion 2 is moulded integrally with a tubular wall 2c which initially extends externally of the base portion, downwardly away from the conical body portion 1 to enable the cone to be stripped from its internal mould. After stripping, the tubular wall 2c is flexed and folded into the body portion to cooperate with the interior of the body portion 1, and is sealed thereto to form a generally annular ballast cavity. The cavity may be filled with a low cost ballast, for example sand or water, before sealing, through the gap between the upper end of the tubular wall 2c and the interior of the body portion 1, whereafter sealing is effected to permanently close the cavity. <IMAGE>

Title: Lighting system for cycles
Inventor: SKINNER VINCENT JOSEPH
IPC: B62J6/00
Filed: 1983-02-10
Abstract: Cycle lights 16 and 17 are energised by a battery 15 when the output from a generator 10 is low. Switchover circuitry, 11 to 14, may be responsive to the frequency of the generator output. Alternatively, switching may be in dependence on the generator output voltage, a series diode (28, Fig. 3, not shown) connecting the battery (29) to the lights 16 and 17. The generator may charge the battery via a resistor (27) in parallel with the diode (29). The generator output may be limited by a Zener diode 24. The battery and control circuitry can be located in a housing (40, Fig. 4, not shown) which clips to the cycle frame and has a multiple connector for connection to the generator and lights.

Filed: 1983-02-11
Abstract: An instrument for sensing a characteristic of a fluid by its effect on a vibrating tuning fork exposed in the fluid comprises a non-magnetic wall (4) forming in use a boundary to the space occupied by the fluid; a W- shaped magnetic yoke the three legs (1,2) of which extend through the wall in use into contact with the liquid with the base part of the W on the outside of the wall; the end of the central leg (2) being bifurcated to form tuning fork tines (3) each spaced from, and facing in its direction of vibration, a respective adjacent one of the outer legs; and a coil (5) associated with the base part of the W and arranged to be energized with an oscillating electrical current whereby periodic magnetic flux (6) is produced in the yoke to cause the tines to be vibrated as a result of the periodic magnetic attraction between each tine and the adjacent outer leg. A piezoelectric crystal detector (7) is connected to the base of the yoke to sense oscillation of the tuning fork. Associated circuitry is connected to the coil (5) and detector (7) to derive the density, viscosity, or the presence or absence of particular fluids from the resonant frequency of vibration or the attenuation in the vibration of the tuning fork. <IMAGE>

Title: Purification of sugar syrups
Inventor: GUDNASON GEIR VALBERG
IPC: C13B20/12
Filed: 1983-03-15
Abstract: Color, turbidity, flavor, and odor are removed from impure, high Brix, sugar syrups by entrapping the sugar impurities in an insoluble, primary calcium phosphate or aluminum hydroxide floc at neutral pH, dividing the sugar syrup into a small and large portion, aerating the small portion of the syrup at a specific Brix, recombining the small portion and the large portion; adding a polyelectrolyte to convert the primary floc into a secondary floc to which the air bubbles easily adhere and to cause flotation of said secondary floc, thus forming a scum mat at the top of the vessel. The purified sugar syrup is then filtered with or without activated carbon and small amounts of a filter aid to produce a sugar syrup with reduced color, turbidity, flavor, and odor. The sugar in the scum is recovered by mixing it with water and allowing a second flotation to take place without any further aeration or chemicals addition.
