Abstract: In a transmission system having range shift levers mechanically linked to couplers and shiftable between first and second positions to select ranges of gears and electro-hydraulic powershift clutches for selecting a gear within the range selected by the range shift lever, the powershift clutches are located on each side of at least one of the couplers, between the input shaft and the coupler and between the output shaft and the coupler. A dump solenoid is controlled by operation of a clutch pedal to release fluid from the powershift clutches as the clutch pedal is depressed but before it reaches the fully depressed position so that the coupler is not being driven when coupler shifting takes place.

Abstract: A method of controlling an inching clutch in response to movement of an inching clutch pedal between up and down positions in a power shift transmission comprises, for clutch pedal positions below a limiting position, applying to the clutch a control signal which is non-linearly dependent upon the position of the pedal and, for clutch pedal positions above the limiting position, applying to the clutch a control signal which linearly increases with time and is entirely independent of clutch pedal position. Within one range of clutch pedal positions below the limiting position, the magnitude of the control signal applied to the clutch is constant when a high gear speed ratio has been selected, and varies linearly with the clutch pedal position when a low gear speed ratio has been selected. Within a range of pedal positions adjacent the fully down position, the control signal remains constant regardless of the position of the pedal.

Abstract: In order to polish a zone (9) of a surface (2) so as to leave visible marks, the zones of the surface which are not being worked on are covered by a mask (4) having an adhesive face and a face covered with an abrasion-resistant metal layer (7) with the total thickness (e) of the mask not exceeding 40 .mu.m so that the non-polished margin along the edge (8) of the mask (4) has a width (l) of less than about 0.1 mm, thereby making it invisible to the naked eye so that adjacent zones appear to come directly into contact without a visible separating margin.

Abstract: In a process for starting a high pressure gas discharge lamp (GDL) of a motor vehicle of a type for which an alternating voltage is developed from a direct voltage, the alternating voltage being fed to an ignition device to ignite the high pressure gas discharge lamp, a lamp voltage and/or a lamp current is measured, an actual value based on lamp current and/or lamp voltage is compared with a desired value and after ignition of the high pressure gas discharge lamp for a predetermined time span, or period, an additional power is added to an operational power of the high pressure gas discharge lamp by means of changes in the alternating voltage which, on the one hand, is limited by a maximum permissible lamp current and on the other hand is terminated at the end of the predetermined time span.

Abstract: This method for establishing blood pressure in an artery employs the measurement results from two non-invasive sensors (5, 6) of artery diameter at two closely spaced locations (3, 4) separated by a distance .DELTA.x. The method provides for measuring the time spread .DELTA.t(7) between each pair of diameter measurements and establishing the propagation velocity of the pressure wave (9). Next, this value is compared with an expression (11) of the form c(D)= c(D, .alpha., .beta., .gamma., . . . ) which takes into account the physical behavior of the artery. This comparison permits one, following adjustment (12) based on a mathematical procedure for minimizing spreads, to calculate the parameters .alpha., .beta., .gamma., . . . of the relation given hereinabove. By replacing the parameters .alpha., .beta., .gamma., . . . by their values in a relation (10) D(p)= D(p, .alpha., .beta., .gamma., . . .

Abstract: An apparatus and method for detection of icing onset and ice thickness upon an accretion surface utilizing ultrasonic echo ranging techniques, including propagation of ultrasonic waves through a buffer block. A portion of the wave energy is reflected by reference reflection means and another portion of the wave energy is propagated to the ice accretion surface and to a reflecting interface. The reflecting interface is represented either by the accretion surface in absence of icing, or by a thin ice layer at the icing onset, or by the ice/air interface of an ice layer accreted upon the accretion surface. Reflected waves are transduced to electrical signals. Relative signal amplitudes and time delays provide measures of particular icing conditions upon the accretion surface, and are appropriately resolved into calibrated signals indicating icing onset, ice thickness, and ice accretion rate.

Abstract: A reciprocating pump comprises a plurality of pump sections, each pump section having a suction inlet and a discharge outlet, the inlets all connecting with a common passageway through which the pumped fluid is supplied and the outlets all connecting with a common discharge passageway through which the pumped fluid is discharged. Each pump section includes a bellows which reciprocates to alternately produce suction and discharge strokes, with a change-over period between strokes. A drive control for the bellows delays the start of strokes by the bellows so that when one pump section is in a suction stroke or a change-over period, at least one other pump section is in a discharge stroke. The arrangement reduces variations in pressure in the discharge from the pump.
