Abstract: A heating system providing an instantaneous source of hot water to either a water sink or to a source of heat or to both includes a hot water source (10) for receiving cold water and converting it to hot water, where the cold water is converted to hot water essentially instantaneously, obviating the need for a water storage tank. The heat in the water is converted to a source of space heat utilizing a water to air heat exchanger (20). The system also includes means (25) for directing the flow of hot water to the water to air heat exchanger (20) in response to a demand for heat signal, and means (21) for directing the flow of hot water to hot water sinks (19). A flow rate detector (30) monitors the flow to the sinks and provides a signal indicative thereof. In response to this signal, means (22) for controlling the flow of hot water to the water to air heat exchanger (20) allows hot water to flow only to the hot water sinks (19) when the flow rate exceeds a predetermined threshold rate, as determined by the flow rate detector (30), by interrupting the demand for heat signal.

Abstract: A linearity correction circuit for television transmission operates at intermediate frequency to introduce appropriate pre-distortion into the amplitude envelope to compensate for non-linearity in the power amplifier stages. An array of parallel current sources (11), each of which is independently adjustable in response to the perceived requirement for pre-distortion over a corresponding amplitude band, to inject a current sufficient to introduce an appropriate differential voltage at the output. The circuit provides for the independent correction of each amplitude band, so that it is capable of operation under microprocessor control in real time.

Abstract: A voltage to current converter circuit manufactured with a MOS process generates a linear reference current over a wide bandwidth and operates with an input signal (3) that varies to either supply rail (1,2). A voltage divider network (6,7) scales an input voltage for conversion to a linear current by a cascode current mirror (11) and a gain resistor (14). The value of the gain resistor (14) determines the transconductance of the conversion from voltage to current. A second current mirror (12) provides feedback to keep the reference current accurate. An output stage makes available high impedance source and sink current output terminals (35,34) wherein a source current and a sink current relative to the reference current are provided. Several voltage to current converter circuits (10,10′) may be coupled together to provide addition, subtraction, multiplication, and other circuit and system functions.

IPC: G01J5/00
Filed: 1989-04-19
Abstract: Dual pyrometric detectors (10,12) and method measure the temperature of a remote heated object (17) in the presence of ambient radiation. One detector (10) measures emitted radiation from both the remote object (17) and from the environment, and the other detector (12) measures radiation predominantly from the environment alone. The output signals from the two detectors (10,12) are processed electronically to yield the detected radiation from the remote object alone. The result can then be electronically processed to display the pyro­metrically-measured temperature of the remote object.

Abstract: A process for the preparation of a catalyst for the copolymerisation of ethylene by the gas-phase fluidised bed process involves absorbing a titanium- and magnesium-containing active component which has been reacted with an alcohol as complexing agent, in the presence of a polysiloxane, from homogeneous solution onto a finely divided silicon dioxide by evaporation of the solvent, and subsequently preactivating the resultant homogeneous catalyst precursor by treatment with the alkylaluminium compound and the Lewis base in an inert hydrocarbon solution. Copolymers prepared using the above catalyst are used to produce films having a low tendency to block.

Abstract: A fluid motor (97) is set into the return flow of a hydraulic or pneuma-machinery. This fluid motor (97) has a relatively large consumption capacity to revolve at low speed, but it can be a low pressure motor. The motor (97) is utilized to revolve or oscilate one or more control devices which may be used to control the operation of the machinery with the return flow whereinto the fluid motor (97) is set. Specific additional matters are then proposed to secure the smoothly timed and reliable operation of the fluid motor and of the controller(s) which it drives. 
     This control arrangement with the fluid motor (97) in the return flow fluid line may be utilized to control the operation of a high pressure pump. This pump may have medial pressure (8, 9) and high pressure (5, 6) pistons, reciprocating in respective cylinders, as well as inner- and outer- chambers with deflectible separators (58) between these chambers in order that the outer chamber may contain a lubricatious fluid while the inner chamber can then contain a non-lubricative fluid, as for example, water. 
     The fluid motor (97) in the return fluid line may be replaced by another motor, for example, an electric motor with a reduction gear, to enforce a low speed operation of the control device(s). If the apparatus of the invention is a complete use of all details of the invention, a pump can provide a flow of water with pressures in excess of 30 000 psi.

Abstract: An HDTV picture is transmitted in a 625/50 MAC channel using bandwidth reduction techniques. In an 80ms coding branch motion compensation is provided by generating motion vectors for each block of the picture. The motion estimation is performed on a downfiltered and subsampled signal, and peaks in the phase correlation surface are estimated by an inverted-V interpolator function. Vectors are assigned to the blocks by determining the assignment error over both a field period and a frame period and summing the two. A "menu" of eight vectors is available for each block. 
     To assist compatibility, samples are repositioned before transmission by calculating the average motion per field for each block, rounding the resultant to the nearest even number of pixels and picture lines per field period, and displacing the samples in dependence upon the resultant displacement value and upon the field number from which the sample is derived. Furthermore, a filter is selectively included to provide an attenuating dip centred on 12.5 Hz.
