Abstract: The present invention relates to the automatic checking of images and finds particular application in the checking of images recorded on microfilm. 
     In common with known equipment the checking device comprises a scanning array, a field of view and means for providing relative movement between the two. In the known equipment, scanning of the image is carried out in a direction orthogonal to the direction of relative motion, this results in poor data collection for image edges orthogonal to the direction of relative motion. In order to improve the quantity of data in respect of these edges, in the present invention the scans are inclined with respect to the direction of relative motion. 
     In order that the images may be checked at a speed in excess of that possible by the known analysis of the images in real time, the present invention provides for the use of sampling windows along each scan to track the edges of the images. This tracking is significantly improved by allowing for the displacement of a sampling window by a preset distance along the scan in accordance with the analysis of the data within that window in the previous scan if that analysis failed to detect the image edge.

Abstract: A wind energy device uses an airfoil section 1 to generate a vortex 25 at its tip, thus concentrating the wind energy incident on the leading edge of the airfoil 1 in the tip vortex. To increase the wind energy in the vortex 25, a wind deflector 14 is mounted close to the airfoil tip and is arranged so that it deflects wind incident on it into the vortex 25 in a generally tangential direction and in the direction of rotation of the vortex 25. A rotary device 24, preferably a Savonius rotor, is mounted in the path of the vortex 25 so as to be rotated by the wind in the vortex 25, and drives an electricity generator.

Abstract: A vehicle speed control system is disclosed which is primarily intended for heavy vehicles and which is arranged to 'anticipate' an uphill section of road immediately following a downhill section, so as to prevent loss of momentum gained on the downhill section. A comparator 20 compares an actual speed signal Vs with a driver-settable desired speed signal Vr, and produces an error signal Ve by means of which an output unit 30 adjusts the engine power to reduce any speed error to zero. A level changing circuit 27 produces an output equal to Vr in normal circumstances, but which follows Vs when the vehicle accelerates downhill. This output is fed through a memory 29 via a switch 28 which is open when an acceleration-deceleration unit 110 detects that the vehicle has reached the foot of the hill. Memory 29 therefore stores a signal Vr' representing the speed at that time, and comparator 20 therefore increases the engine power when the vehicle speed has fallen below this augmented reference speed, instead of waiting for the speed to fall to the original reference. A comparator 108 detects when the vehicle speed on the uphill section has fallen to the original desired speed and closes switch 28 so that the reference reverts to Vr. Unit 109 closes switch 28 to ensure that the reference is brought back from Vr' to Vr if the vehicle speed increases (such as if the downhill section is followed by a level section instead of an uphill section).

Abstract: Method of bringing gases into contact with compostible or partially composted material, by which the material resting in the form of a mass on a layer of particulate material is traversed by a gas, preferably air, this air being introduced into the mass by gas-distributing means, e.g. a main pipe (1) and a plurality of perforated branch pipes (2), embedded in or covered by the layer of particulate material, and in which the layer comprises a first-part layer (8) of relatively coarse particulate material, intended to serve as a protection for the gas-distributing means and as a distributing filter for the through-flowing gas, and a second-part layer (9) arranged upon the first-part layer and comprising relatively fine particulate material, the second-part layer being intended to distribute the through-flowing gas before the gas is introduced into the compostible or partially composted material. The second-part layer of the layer comprises a mixture of the relatively fine particulate material as ballast material, as well as a binding agent, it having such a particle size distribution and the ingredients being present in such mixing proportions that this second-part layer acquires an open-pore structure having a pressure drop suitable for uniform gas distribution while, at the same time, it is able to withstand the weight of heavy vehicles.

Title: Liquid fuel system.
Inventor: PEFLEY RICHARD KRAMER
IPC: F02B13/08
Filed: 1980-08-01
Abstract: System for improving performance of spark ignition, internal combustion engines using fuels such as liquified petroleum gas (LP-gas), which have conventionally been stored as a liquid and delivered to the engine as a vapor. This system stores such fuels as liquids (10) and delivers the fuel to the engine inlet air stream as a liquid. The absorption of heat by the vaporizing fuel lowers engine inlet air temperature, increasing its density and permitting more fuel to be burned in each cycle. Vaporizing heat in a pilot line (17) provides the cooling to the liquid fuel in the main fuel line (20) and provides fuel to maintain the engine idling. A member (27) slides within a fuel delivery chamber (25) for covering or uncovering a series of orifices (26) through which the liquid fuel passes into the inlet air stream of the engine.

Abstract: Device for controlling the temperature of any medium heated by a heating resistor and in particular of the contents of a heating case for soil-less cultivation. So as to avoid both the overheating of the contents of the case and of the bottom of the case, the control device comprises both a first probe (13) consisting of a variable resistor with negative temperature coefficient combined with a first circuit (Z3, D10, Z2) for regulating the interruption of heating of (Z1) by commanding the triacs (D2 and D1), so that the temperature of the medium contained in the case cannot exceed the temperature T1 displayed by the potentiometer (17), and a second probe (23) consisting of a variable resistor with positive temperature coefficient inserted in the circuit for command of (D2 and D1), so that as soon as the impedance of (23) rises to a specified value when its temperature reaches a value T2, the triac (D2) disconnects the conductor of (D1) and thereby interrupts the AC voltage-fed heating of (Z1). Thus, the element (Z1) cannot damage the wall heated during the rise in temperature of the contents of the case. <IMAGE>
