Abstract: This invention relates to vehicle seats. 
     The vehicle seat comprises a back rest (11) mounted for substantially vertical movement relative to a base part (1), and a seat rest (10) movable simultaneously with the back rest but also arranged to tilt relative to the back rest as the seat rest rises and falls. Such tilting is about horizontal transverse axes such that the seat occupant's ankles remain stationary whereas his knees swing about an axis through his ankles. (See Figure 1). 
     The invention is applicable to heavy duty vehicles and more particularly to vehicles designed to move over rough terrain.

Abstract: A voltage regulator circuit for a liquid crystal display in which compensation for the temperature dependent nature of the operating characteristics of the display is achieved using integrated circuit components. This is achieved by utilising the temperature-dependent characteristics of a forward bias PN junction diode (323, 324), the number of diodes providing selection of the temperature gradient of the output voltage. The PN junction diode may be formed, effectively, by an NPN transistor 305 with its base and collector terminals common. Alternatively the temperature dependent element may be formed as an integrated resistor (362, 366). The entire circuit is made as an integrated circuit, preferably using MOS technology, and adjustment of the temperature gradient of the output voltage and the voltage level thereof are provided for by techniques compatible with integrated circuit structures. In one embodiment a non-volatile memory device (461, 462) is used to control a set of analogue switches (421-424; 451, 454) in series with respective integrated resistors (401, 404; 431, 434). The output voltage is stabilised by providing a standard voltage source within an operational amplifier, for example utilising the difference in the threshold voltage between two MOSFET, so that the output voltage is not affected by variations in the supply voltage. In order to reduce the power consumption to a minimum the operational amplifiers may be cyclically activated by a periodic clock signal and a sample and hold circuit (396, 397) is provided.

Abstract: A downflow evaporator for concentrating a descending stream of liquid containing solids comprises a bundle of downflow tubes having open upper ends affixed to an upper tube sheet and open lower ends affixed to a lower tube sheet, the tubes receiving the stream of liquid through the upper ends and discharging it through the lower ends. The liquid is caused to cascade over the entire surface of the upper tube sheet whereby the liquid is distributed thereover and over the open upper tube ends. A covering is placed over the upper end of each downflow tube and spaced therefrom so as to prevent the liquid from dripping into the central portion of the tube whereby the stream of liquid descends peripherally along the inner surface of the tube.

Depending on the direction of rotation of the central drive wheel the fast-mode idler arm is pivoted from an inoperative position into a first or second operative position respectively. In a first position control means which are adjustable to two positions limit the pivotal movement of the switching lever to movement into a first, partly pivoted operating position, in which first position of the control means the fast-mode idler arm is uncoupled from the switching lever so that the fast-mode idler arm is pivoted. In the second position of the control means the switching lever is pivotable into a fully pivoted second operating position, the fast-mode idler arm then occupying the inoperative position through the coupling of the fastmode idler arm with the switching lever and the normal-mode idler arm being pivoted into the operative position. In both operating positions the switching lever is also coupled to the head slide.

Abstract: The invention resides in utilizing a servo motor (9) to drive the label feed and employing a control system for the servo motor which is responsive to the rate of feed or speed of the surface to be labelled (2) as it is advanced to the labeller. The control system on receiving an instruct to label signal accelerates the servo motor smoothly from zero to the desired labelling speed while the surface to be labelled is advanced toward the labeller a predetermined distance and on receiving an end to labelling signal decelerates the servo motor smoothly from labelling speed to zero while the label feed is advanced a predetermined distance. The arrangement is such that upon an instruct to label signal being fed to the control system at a predetermined position of advance of the surface relative to the labeller the labeller will accelerate a label from a predetermined start position and deliver same to touch down on the surface to be labelled at the precise desired point with the label moving at the same speed as the surface and upon an end to labelling signal generated by a label feed sensor being fed to the control system the labeller will decelerate to bring the next label to be delivered to said predetermined start position in preparation for the next instruct-to-label signal.

Abstract: A fuel-air metering system functioning according to precise flow and geometrical equations. An air throttle valve (42) and fuel valve (80) are positively linked with the flow crossectional area of each valve proportional to that of the other. Fuel pressure drop across the fuel valve is regulated in precise proportion to the pressure drop across the upstream orifice of a two orifice in series (48,50) air flow system which bypasses the air throttle (42). Careful shaping (142 143) of the air throttle (42), the bypass system orifices (48,50) the fuel valve (80) passage geometry, and the servo valve fuel regulation system (91,95,99,66,68,70) results in an accurate proportioning of fuel flow to air flow.

Abstract: The invention overcomes the problem of excessive dilation of the introitus, and also permits the interior of the vagina to be dilated independently of the introitus. 
     Essentially, the vaginal speculum (1) comprises an introitus engaging ring member (2) and a pair of vagina engaging members (3,4) of arcuate shape slidable through the ring member (2). The introitus engaging ring member (2) is inserted into the introitus and the vagina engaging members (3,4) are moved through the ring member (2) in the direction of the arrow A. As the vagina engaging members (3,4) are moved through the ring member (2) into the vagina, ends 9 and 10 move apart, thereby dilating the interior of the vagina. 
     In another embodiment of the invention the vagina engaging members (3,4) are pivotally connected (30, 31) to the introitus engaging ring member (2).

Abstract: Test apparatus enables the relative timing of two signals picked up by probes 16, 18 to be determined. The two signals are fed, via switchable polarity and level changing circuitry 10, 11, 13,14 to a simple flip-flop 12, which comprises two cross-coupled transistors plus two input transistors. With both inputs at 0, the flip-flop is in an abnormal state with both cross-coupled flip-flops in the same state. The first input signal to go to 1 causes the flip-flop to enter a corresponding one of its two normal states (the cross-coupled flip-flops in opposite states). Detection circuitry 24 and display means 15 signal this state. 
     A low frequency bias oscillator 20 shifts the sloping transitions of one signal up and down relative to the other, changing their relative timing. For a part of each slow cycle dependent on the relative timings of the two signals, their effective timings at the flip-flop will be reversed. Hence the mean output from 24 will be dependent on the time difference between the two signals.
