Title: Liquid Treatment of Metal Strip
IPC: B65G51/03
Filed: 1979-03-01
Abstract: An apparatus for the liquid- treatment of a metal strip without the aid of conventional support and squeeze rollers used for contacting and guiding the strip, thus preventing carryover of liquid between the treatment tanks of the apparatus comprises successive treatment tanks 7, 8 having horizontally elongate chambers 11 with two rows of oppositely disposed and horizontally aligned nozzles 20, 21, between which the metal strip 6 travels on a liquid bed that is created by the nozzles which direct streams of liquid under pressure,, against the strip at angles that are less than 90 DEG  relative to the plane in which the strip travels. A liquid seal 35 and conventional blowoff device 44, 45 are utilized at each opening through which the strip enters and exits the chambers, as a means of maintaining the liquid within the chamber and preventing it from being carried away by the travelling strip into an adjacent chamber. <IMAGE>

Title: Force limiting device for an actuator rod
IPC: F15B15/14
Filed: 1979-04-04
Abstract: In a force limiting device for an actuator rod having a valve actuator rod 76 coupled to a piston 66 slidable in a cylinder 64, one side of the piston being loaded by high pressure gas in a chamber 46 and the other side of the piston supplied with or exhausted of hydraulic fluid, the force applied to the actuator rod 76 when the valve has been moved by the hydraulic fluid from its closed position to an open stop position is arranged to be less than the initial valve opening force. The piston includes an interior cylindrical bore 70 which slidably receives a piston head 82 integral with the actuator rod 76. Atmospheric pressure communicates with the bore 70 through a passage 98 to act on the larger side 106 of the piston head, the smaller side 84 being in communication with the cylinder 64 through a clearance space around the rod 76. During valve opening the hydraulic fluid produces a force on the piston head 82 due to the pressure acting on the large area of the piston 66 but when the piston 66 forcibly abuts a piston stop 110 the hydraulic fluid becomes effective primarily only on the smaller piston head side 84 thereby limiting the maximum tensile force on the actuator rod when the valve reaches its fully open stop position. <IMAGE>

Title: Improvements in or relating to display processors
IPC: G06T15/40
Filed: 1980-01-25
Abstract: In order to enable an image of a scene, comprising one or more regions each enclosed by a respective set of planes defined by a boolean expression relating the planes of the set one to another, to be generated on a raster scan display, a processor is used to produce, from the boolean description of the scene, an electrical signal capable of generating that image. The processor is adapted to determine what is to be shown in each part of the display from depth values indicative of the distance of each plane from the display screen, first and second increment values respectively indicative of depth value changes between two raster points in two mutually non-parallel directions, and property codes indicative of whether each plane is a front surface or a back surface of the image and of the positions of the planes in the boolean expression of the set of planes including that plane. The processor may be used to generate a projection of a three-dimensional image on the screen, or alternatively it may be used to generate a cross-section through such an image.

Abstract: In a process for achieving heat exchange in a latent heat store 10, between a heat storage medium 14 and a heat vehicle medium 37, by way of a heat transfer surface 30 separating the two media, the heat storage medium 14 (e.g. a grit) is brought into a fluidized state by a fluidizing medium e.g. a paraffin oil 16 (or air or an inert gas, Fig. 3) which is substantially immiscible with the heat storage medium. A temperature sensor 39 may control a pump 20 to regulate the degree of fluidization. The heat vehicle medium 37 may be a water-glycol mixture circulated through a solar heat collector 36 or through the evaporator of a heat pump (e.g. 56, Fig. 2). The heat store 10 may provide heat for a heating or hot water system (e.g. via a circuit 40, 42, 44). Supplementary heat for the heat store may be provided by an electric heater 48 or by an oil burner (.e.g. 70, Fig. 2) in the circuit 40, 42, 44. <IMAGE>

Title: Controlling the grey levels represented by a video signal
Inventor: COATES PHILIP VALENTINE
IPC: H04N5/14
Filed: 1980-09-03
Abstract: A digital buffer store 25 stores digitised samples of a video signal. A circuit 206 determines the mean grey level (f(b)) of the stored signals and a circuit 28 forms a histogram indicating the number of pixels having various ones of 8 possible grey levels. Circuit 29 determines the dispersion of the histogram about the mean grey level. In principle, circuit 29 could determine from the mean level and the histogram the statistical distribution of pixels amongst the grey levels and from that determine the standard deviation as a measure of dispersion. In practice, the circuit 29 determines an empirical approximation to the dispersion,   <IMAGE>  where  n = number of binary bits = 3  Ni = number of pixels having a grey level i  A = f(b) = mean grey level  NA = number of pixels having the mean grey level. This equation is advantageous as it operates on powers of 2. The determined values of f(a) and f(b) are compared with empirically derived desired values and servo the gain and D.C. Offset applied to the video signals in a circuit 20. <IMAGE>

Title: Moving band press
IPC: B30B9/20
Filed: 1980-10-01
Abstract: A method and apparatus for dehydrating slurry 15a supplied onto an endless filter belt 10 involves pressing the slurry between cooperating rolls 1, 4 arranged above and below the endless belt. In order that the slurry passes through the gap at a rate as large as possible while being effectively dehydrated, the upper roll is positively driven at a peripheral speed which is at least equal to that of the lower roll but does not exceed a speed 30% higher than that of the lower roll. The upper roll 1 is advantageously provided on its peripheral surface with double oblique grooves which urge the slurry to the central area of the endless belt. Further, a plurality of rows of elastic soft endless belts 18 may be arranged between the endless filter belt and the lower roll to promote the discharge of the water squeezed out of the slurry, thereby improving the dehydration effect and increasing the throughput. <IMAGE>

Patent GB-2064717-A (GB)
Title: A pneumatic spring for vehicles
IPC: B60G11/27
Filed: 1980-12-12
Abstract: A spring has a casing 310 containing a closed volume formed by two coaxial roll bellows 302, 303 which, in conjunction with a partition 318 in the form of a diaphragm, form two part volumes 319, 320. The roll bellows 304, 305 are each supported on respective pistons 304, 305 which consist of two opposed cup-shaped members secured together by a rod 306 and spacer 309 which passes through the partition 318. Variation in the pressures in the two part volumes 319, 320 around the nominal or mid position of the spring is compensated by the flexibility of the partition 318 but for greater deflection or movement of the spring the partition is stretched tight so it cannot provide compensation so that progressive hardening of the spring towards its limit positions is achieved. <IMAGE>
