Patent GB-2126829-A (GB)
Title: Image correction
Inventor: GROVES PHILIP RANGECROFT
IPC: H04N5/217
Filed: 1982-09-09
Abstract: Conventionally image defects arising in a camera tube have been corrected by the application of a standard correction signal predetermined from mainly theoretical considerations. This invention measures the values of a parameter from each of the picture elements, calculates a correction signal from the parameter values and applies the correction signal to correct the image defects. Calculation of the correction signal preferably includes multiplying each of two adjacent line or field parameter values (VALUE 1, VALUE 2) by a respective reference signal (V REF. 1, V REF. 2) which has a frequency equal to half the frequency of occurrence of the picture elements whose values are being multiplied, the reference signals (V REF. 1, V REF. 2) being in anti- phase with each other, and summing the multiplied values, whereby calculation of the correction signal includes a smoothed interpolation. The scaling function of digital to analog converters (10, 12) is used to effect the multiplication and in this case the parameter values are converted to digital form prior to multiplication. <IMAGE>

Title: Apparatus for measuring the delay time of electrical pulse signals
Inventor: FRANK PETER
IPC: G01S7/4865
Filed: 1983-05-04
Abstract: An apparatus for measuring the delay time interval between electrical pulse signals, particularly in conjunction with electrooptical range finders. A coarse measuring counter counts clock pulses from a quartz oscillator during the interval and a fine measuring interpolator determines the residual time from the end of the interval to the next clock pulse. Residual time at the start of the measuring interval is avoided by exactly synchronizating the start of measurement with a timing pulse front (n+2) of the quartz oscillator.

Title: Feed bin
Inventor: ROBERTS BURFORD ALAN
IPC: A01K39/012
Filed: 1983-08-08
Abstract: A feed bin has a steeply, typically 39 DEG  to the horizontal sloping base 4 for directing feed into a deep, wide trough 2 whence it can be removed for use. Since feed is removed from the bottom of the bin it does not become stale there. The steep slope ensures that poorly flowing feeds such as bran will flow without requiring agitation. The deep, wide trough provides depth for internal friction build up in freeflowing feeds such as linseed to prevent spillage thereof. <IMAGE>

Title: Temperature control of fluidized bed reactors using heat pipes
Inventor: MCCALLISTER ROBERT A
IPC: F28D15/02
Filed: 1983-08-26
Abstract: A fluidized bed reactor system for introducing heat energy into or removing heat energy from fluidized reactants undergoing reaction includes, in a first embodiment, a fluidized bed reactor for fluidizing a particulate material in a fluidizing medium and a heat generator for supplying heat energy to the fluidized bed. A plurality of heat pipes interconnect the heat generator and the fluidized bed reactor with the evaporator portions of the heat pipes extending into the heat generator and the condenser portions thereof extending into the fluidized bed. Thermal energy from the heat generator is absorbed by the evaporator portions of the heat pipes and conveyed through the heat pipes to the condenser portions where the thermal energy is transferred to the fluidized bed. Since heat pipes transfer thermal energy at a relatively constant temperature throughout a wide range of thermal flows, heat energy can be introduced into endothermic fluidized reactions at a relatively constant temperature to achieve preferred reaction rates. In a second embodiment, the evaporator portion of the heat pipes extend into the fluidized bed and the condenser portions extend outwardly of the fluidized bed to a heat sink.

Title: Liquid change detector
Inventor: TOLCHARD ADRIAN CAREY
IPC: G01N29/024
Filed: 1983-08-26
Abstract: A liquid change detector 44 (70) incorporates an ultrasonic transducer 30 coupled to the outside of a wall of a container 12. The transducer 30 is adapted to operate in a pulse/echo mode, so as to generate an ultrasonic pulse and to receive ultrasonic echo pulses after propagation through the liquid 42 in the container 12. Amplified return signals from the transducer are supplied to a gated signal analyser 54, (72) which is gated to operate during a predetermined time interval in which an echo pulse is expected to be received if the velocity of sound in the liquid has a first value, but in which no echo pulse is expected if the liquid changes so that the velocity of sound has a second value. The output of the gated signal analyser 54,72 may be used to give a visual indication that the liquid 42 has changed, or may be used to operate valves so as to control flow of the liquid 42 appropriately. The detector may be used in a brewery to distinguish between cold beer and hot water with which pipelines are cleaned. <IMAGE>

Title: Regulating the temperature intake air drawn in by I.C. engines
Inventor: BENDIG LOTHAR
IPC: F02M31/06
Filed: 1983-11-10
Abstract: The unfiltered air pipe 17 of an air filter is divided into two conduits 21,22. A first control valve 32 has vanes 34,35 which are influenced by a thermostatically-controlled, vacuum- operated setting-motor (31), Fig. 1 (not shown). Vane 34 in first conduit 21 controls the through-aperture 23 in a heated air pipe 19, and vane 35 in second conduit 22 controls an unheated air pipe 18. A second control valve 50 disposed downstream of the vane 35 of the first control valve 32 is operated by a wax thermostat 54 exposed to the mixed air temperature. In each of its end positions, the valve 50 closes the unheated air pipe 18 or the through- aperture 24 in the heated air pipe 19, respectively. During idling and partial- loading operations, the thermostatically controlled vacuum regulation permits intake air to be supplied at a relatively high temperature. During full-load operation, the valve 50 regulates the supply of intake air at a lower temperature. The apparatus prevents full-load icing and facilitates rapid warm-up. <IMAGE>
