Patent EP-0288252-A2 (EP)
Inventor: HAWKER MICHAEL JOHN
IPC: B60T15/02
Filed: 1988-04-20
Abstract: A solenoid operated control valve for use as an inlet and/or exhaust valve in pressure modulator has a flat valve element (30) cooperating with a flat valve seat (28) to control the flow of fluid through the valve. At least a portion of the solenoid armature (10) has opposed parallel flat surfaces and is disposed within a gap (12) defined between parallel faces for movement axially within the gap (12) to operate the valve. The flat valve seat (28) is disposed in the plane of one of the parallel faces and one of the parallel faces is a face (16) of the stator (18). All required settings more particularly magnetic reach, the energised gap and excess valve travel to compensate for wear are set automatically by spacers (t₁, t₂, t₃). The spacers give the required settings directly from their own thickness and not through other component dimensions in combination. This has very important implications for production since the direct spacer automatically gives the required dimension, whereas indirect ones can only be chosen by assembly measurement or selective assembly both of which are expensive.

Abstract: A digital weighing scale is compensated for the effects of off-center loading by determining the position of the load and calculating a corrected weight value according to such position. Position sensing transducers (16,17) are mounted on the load cell to provide information regarding the position of the load on the weighing scale. An expression for corrected weight as a function of load position and magnitude is determined for the particular scale and stored. The expression is used to calculate corrected weight according to the magnitude and position of each weight placed on the scale. The load cell may include a counterforce of substantially any type including single bending beam, dual bending beam or capacitive structure, and the load magnitude and position sensors may be of substantially any type including strain gages and capacitive sensors.

Abstract: A vehicle cab (10) with a window aperture (11) closed by a pivotable glazing panel (12). The window aperture is of vertically tapering form such that the width 'W' of the lower regions of the aperture is less than higher regions of the aperture and the glazing panel (12) is of a similar vertically tapering form. A glazing panel mounting structure (13) allows the glazing panel to be moved from a generally upright closed position to a generally horizontal open position (12′) by raising the panel in a vertical sense so that the lower narrower portion of the panel is in alignment with a wider higher portion of the aperture and then pivoting the lower narrower portion of the glazing panel about a first generally horizontal axis (21) through the wider higher portion of the aperture to its generally horizontal open position. The locus (60) of the glazing panel as it moves between its closed and open positions may be controlled to a predetermined pattern by a linkage (42, 49, 50, 51, 52) which inter-connects the movements of the mounting structure and glazing panel relative to the cab.

Abstract: The invention relates to a method for making a concrete structure having a lower surface approximately horizontal and separated from the ground. Formwork panels (1) are horizontally disposed and supported by a shoring structure (10,11). These panels are provided, on the one hand, with demountable means for solidly attaching each with its neighbours and, on the other hand, on their lower part, with stiffening elements solidly attached to the panels forming parallel girders. After the concrete has set, the formwork is lowered slightly in order to lay it down onto rolling or sliding means carried by the shoring structure and the entire formwork is moved horizontally until the panels can be demounted without being obstructed by the concrete structure. <IMAGE>

Abstract: Waveform data obtained in a borehole by a tool having a sonic source and an array of sonic detectors is analyzed to obtain an image of formation features within several tens of feet of the borehole, such as fractures, bed boundaries and other boreholes. A value of background sonic slowness is derived from the data and used to determine the sonic energy transit time from the source to each detector via each point in a grid of points extending into the formation and along the borehole. The time for a particular detector/point pair is used to extract the amplitude of the waveform from that detector at that time relative to operation of the source. Such amplitudes for the same point and for different detectors and tool positions are cumulated. The final values for all points are plotted as a variable density display which provides the desired image.

Abstract: The receivers (E1, En) connected to a bus line (BL1, BL2) each contain a clamping circuit by means of which the input voltage is clamped to the signal level which occurs at one of the two states of binary signals on the bus line (BL1, BL2). A comparator (T3) outputs a signal indicating the second state of the binary signals when the difference between the clamping potential and the signal level occurring on the bus line exceeds a predetermined value. The output signal of the comparator (T3) is used for controlling a transformer (U2) fed with high-frequency clock pulses. The invention is used in bus systems, the receivers of which are DC-isolated from the bus line by means of a transformer. <IMAGE>

The apparatus for chemical analysis comprises a detector arrangement (8) which contains at least one light source for transmitting light onto the temporarily separated substances of the sample and onto the carrier substance, and which contains a receiver arrangement for measuring the intensity of the light affected by the substances over a prescribed spectral range and over a prescribed period. Moreover, an evaluation unit (12) is present which combines in a data matrix X the spectral values of each measurement that are determined in the detector arrangement (8), and which determines the concentration values of a substance by estimation after a singular value decomposition of the data matrix X. The evaluation circuit (12) further computes the concentration values of the carrier substance by means of approximation through a linear temporal characteristic, and computes from this the spectral values of the substances of the sample and of the carrier substance. <IMAGE>

Abstract: A method and apparatus for controlling operation of a heating system (particularly a central heating system) including a boiler directly heating and passing water to a pipe network provides for sensing the temperature of the pipe network at a position therein remote from the boiler and controlling operation of the boiler in accordance with that sensed temperature. 
     The apparatus includes switch means (42') (operational amplifiers or comparators) - responsive to a voltage output by a device including a transducer (132) sensing the temperature of the pipe network and - operable to allow the boiler to fire until the sensed temperature reaches a first level and then prevent the boiler firing until the sensed temperature falls below a second level less than the first. 
     The two temperature levels may be varied, and the second level may be varied in dependence upon an ambient temperature remote from an area being heated. 
     An SCR is provided controlling operation of a relay in the power supply to a fuel control valve for the boiler - the SCR being controlled in response to the difference between the voltage output of the temperature sensor and a reference voltage. 
     Operation of the relay may be further controlled by a transistor itself controlled in response to the difference between the voltage output of the temperature sensor and a reference voltage. 
     The apparatus may include an LED illuminated when the boiler is disabled so as to provide an indication thereof. 
     Temperature sensing may be effected by a thermistor or a transducer which passes a current proportional to the temperature thereof and which is connected in series with resistor.
