Abstract: A heater preform (100) comprised of a layer of magnetic material on a layer of nonmagnetic conductive metal comprises a self-regulating heater, and the heater preform is wrapped around or against a solder preform (54) within a length of heat recoverable tubing (52). A conductor wire (70) is inserted into one end (62) of the tubing and a terminal solder tail (14) into the other end (60); when radio frequency current is induced in the heater preform (100) by a surrounding coil, the heater generates thermal energy melting the solder (54) within the tubing (52), terminating the terminal (10) to the wire (70), or two wires together. With sealant preforms (56,58) at the ends (60,62) of the tubing, the sealant preforms melt and the tubing (52) shrinks to conform to the wire (70) and terminal (10) therewithin, sealing the termination simultaneously with forming the solder joint.

Abstract: A gas fired direct contact water heater 2 comprising a casing 4 divided into upper and lower chambers 10 and 12 by a funnel shaped partition 14. The lower chamber 12 defines an annular, water reservoir 24 surrounding a heat conducting wall 18 of a combustion chamber 16 in which gas from a burner 54 is burnt. An outlet conduit 38 with an open upper end 40 below water level S in the reservoir can convey heated water to satisfy user demand when user's valve 46 is opened. Conduit 38 includes a continuously running water pump 42. If valve 46 is closed water from the pump is re-circulated to the reservoir 24 via a conduit 48 and distribution means 50 above heat transfer means 26 extending across the horizontal cross-section of the chamber 10. The heat transfer means 26 comprises metal defining a plurality of interconnected voids which form part of a flow path between the distribution means 50 and the reservoir 24. As the water passes down the flow path the water becomes heated by making direct contact with the hot products of combustion emerging from the flue 20 and passing upwards along the flow path to the flue 6. Conduit 48 includes a valve 52 which is opened   automatically when subjected to slight pre-determined water pressure engendered in the conduit 48 by the pump 42. Seated water is run off when the user's valve 46 is opened. That water is replaced by mains water supplied through a ball-cock 30 and distribution means 28 which is independent of the distribution means 50.

The arithmetic device (9) uses the stored data (Mn-2, Mn-1, Mn, M+1 and Mn+2) to perform arithmetic operations for cancelling crosstalk components (Pn-2, Pn-1, Pn+1 and Pn+2) which come from the adjacent tracks (Tn-2, Tn-1, Tn+2 and Tn+1) to the signal (Pn) read from a track (Tn) which is being traced and then for estimating a true signal recorded on the track (Tn) which is being traced. In this manner, the recorded-information reading apparatus eliminates the crosstalk components by processing the signals recorded on the recording medium (5) without the need to use any special detecting mechanism.

Abstract: A refrigeration system (10) having a modulation valve (54) which controls refrigerant flow to a compressor (14) according to a control algorithm. The need for a compressor throttling valve is eliminated by a load control circuit (118) which operates the modulation valve (54) to perform the function of the throttling valve when load reduction is required. An overload condition of a compressor prime mover (11, 13) overrides the control algorithm and selects a predetermined load control position of the modulation valve. A timer (174) ensures that a predetermined recovery time is provided, before switching back to the control algorithm. The timer also selects the load control position of the modulation valve upon start-up. A heating or defrost mode automatically selects the load control position of the modulation valve for the duration of the mode, as does an ambient air temperature sensor (132) when the ambient exceeds a predetermined value.

Abstract: A packet data communication system employs a congestion avoidance method in which each node measures the round-trip delay occurring when it sends data to a destination and receives an acknowledgement. This delay is measured for dif­ferent load levels, and a comparison of these delays is used to determine whether to increase or decrease the load level. The load level can be adjusted by adjust­ing the window size (number pf packets sent in to the network) or by adjusting the packet rate (packets per unit time). The objective is operation at the knee in the throughput vs. traffic curve, so that the data throughput is high and the round trip delay is low. Control is accomplished at each node individually, without intervention by the router or server, so system overhead is not increased.

Abstract: A three-wire wiring harness to accomplish;
     1) communication from switches in a vehicle door to an on-board microprocessor and   2) transmitting current for energization of actuators to accomplish the respective switch commands.    The switches (26-32) each generate a unique impedance which is characteristic of the respective switch position. The switches (26-32) are connected in parallel such that a change in impedance of any individual switch will produce a change in impedance of the total collection of switches. The net impedance of the collection of switches is recognized by the microprocessor (22) as a result of a change in the resonant frequency of an oscillator. Upon recognition of this impedance, the microprocessor correlates the impedance to respective switch positions and corresponding commands and then implements the respective commands by energizing one of several relays (R1-R4) that define paths for flow of current to respective actuators.

Abstract: A method is described for encoding a first image to produce a second, lower resolution image. For each superpixel group in the first image, a prediction class is formed, based on the values of the pixels in two adjacent superpixels. This prediction class is used to access a table, to obtain a prediction for the corresponding pixel in the second image. If the prediction matches the actual pixel pattern of the superpixel, the corresponding pixel in the second image is set to the predicted colour. If the prediction does not match, then the corresponding pixel in the second image is set to the inverse of the predicted colour, and the actual pixel pattern is stored in a supplementary file. If no prediction is provided, the actual pixel pattern is stored, and the pixel in the second image is set to the colour of the majority of the pixels in the superpixel. The result is a compressed, low-resolution image, along with a supplementary file containing the information necessary to reconstruct the high-resolution image from the low-resolution image. The method may be applied repeatedly so as to form a series of images of progressively lower resolution.
