Title: Bistable relay circuit
Inventor: MCARDLE JOE
IPC: G05B19/042
Filed: 1992-10-13
Abstract: In a heating controller, each of ports 1 and 5 of microprocessor 7 is able to operate two functions, namely the temperature sensing of one location and also the switching on and off of e.g. the boiler or the pump. This is achieved by bi-stable relays 8 and 9 arranged so that the other ports can effect reverse polarity of the relays. In this way, six ports can achieve the operation of two appliances and the temperature sensing of two locations, this conventionally requiring ten ports. <IMAGE>

The spigots are located in the cylindrical bore (5) and a bore (55) of the connection piece (17) to define therewith sealing surfaces (72). Radial expansion of the spigots (51, 53), caused by the pressure medium flowing through the body (39), causes the relatively thin walls of the spigots to be pressed against the surrounding wall of the cylinder liner (3) and the connection piece (17), respectively, thereby to improve the sealing. <IMAGE>
Patent GB-939693-A (GB)
Abstract: 939,693. Measuring rotor unbalance electrically. P. RAIMBAULT. Aug. 17, 1960 [Sept. 17, 1959], No. 28476/60. Class 40 (1). Apparatus for measuring the unbalance of a rotating workpiece comprises strain-gauge resistors mounted on vertical leaf - springs supporting the bearing-blocks, wheieby the magnitude and angular location of the unbalance at each bearing can be ascertained. The rotor to be balanced is supported between bearings 2 (Figs. 1, 2) having interchangeable bushings 1, and supported from suspensions 10 which can be adjusted for vertical height and horizontal spacing. Each bearing 2 abuts against two leaf-springs 5, each carrying two strain gauge resistors 6. The rotor is driven by a motor, producing vibrations which unbalance the resistances of the strain gauges 6. As shown (Fig. 9), each group of strain gauges m. n, p, q is connected into a D.C. bridge, giving a sinusoidal output signal indicative of the unbalance component at that bearing. These signals are fed through amplifiers 66, incorporating a bandpass filter of selectable frequency, to a C.R.O. 31 whose time base is synchronized with the unbalance signal by means of a pulse derived from a preset mark 17 and a mark 16 rotating with the rotor. The synchronizing pulse causes the C.R.O. spot to return to zero, and the angular position of the rotor unbalance at the selected bearing is determined' by bringing the flyback line on to the X axis of the screen. The unbalance signals are also rectified at 26 and fed to meters 27, indicating their peak values. The longitudinal position of the total unbalance is determined by two gauged potentiometers 34, 35 each fed with the unbalance signal from one bearing, the two sliders 37, 38 being jointly moved until a voltmeter joining them reads zero, when their position relative to the ends of the potentiometer represents the position of the total unbalance relative to the two bearings. To determine the components of the total unbalance in two predetermined compensating planes, a third potentiometer 41 is fed with the unbalance signal from each bearing through sliders 42, 43 positioned in accordance with the locations of the compensating planes, and a further slider 63 is ganged to the previous sliders 37, 38. The readings on voltmeters 44, 45 connected between the sliders 42, 63, 43 represent the unbalance components in the individual compensating planes.

Title: Controlling idling of an engine during load changes
Inventor: MIZUTANI KOUICHI
IPC: F02D29/02
Filed: 1996-06-03
Abstract: An idling speed control valve 11 disposed in an idle passage 10 communicates with the intake passage 2 downstream and upstream of the throttle valve 8 to control the amount of the airflow supplied to the idling engine. Neutral start switch 30 outputs an instruction signal to ECU 41 when shift lever S is moved from its neutral range to a drive range. Based on the instruction signal, the ECU 41 computes a duty factor to increase the airflow amount through the idle speed control valve 11 by a predetermined amount. The increased airflow amount is subsequently attenuated to a predetermined magnitude with an attenuation factor (* small Greek alpha *) based on a rate of change (AEN) of the engine speed or on the rate of change of manifold intake pressure measured by pressure sensor 24.
