Title: Valve assembly for a gas trap
Inventor: SCHMID MECHTILDE
IPC: F02M55/00
Filed: 1988-02-24
Abstract: A valve assembly for a gas trap, required for an operating system of a diesel engine, especially in conjunction with measurement of fuel consumption, allows the separated gas to escape directly into the atmosphere under normal operating conditions (Fig. 3) but, in an inclined position of the automobile (Fig. 5) or under faulty functioning of the float-controlled valve situated in the gas trap (Fig. 4) prevents escape of fuel. In a valve chamber (31), a ball (36) of high density and a valve bail (37) able to float on diesel oil, are disposed. The geometry of the valve chamber (31) and the diameters of the balls (36 and 37) are so chosen that the ball (36), in an inclined position of the automobile and therefore of the gas trap and valve chamber, rolls along chamber wall (32) and presses the valve ball (37) into the valve seating (33) to close outlet (35), which is formed in a threaded insert (34, Fig. 2) which can be fitted to the gas trap (13, Fig. 2). In the normal orientation, if the fuel level in the tank of the gas trap is too high, the valve ball (37) floats on the oil and closes outlet (35) (Fig. 4). <IMAGE>

Patent GB-2240335-A (GB)
Title: Ferroelectric materials
Inventor: SHORROCKS NICHOLAS MARTYN
IPC: H01L37/02
Filed: 1989-11-20
Abstract: Compositional modifications are provided for the ferroelectric material lead scandium tantalate (PST), which improve its performance as an electronic material. PST is of particular use in infrared detection applications, in the form of the sensitive material of a dielectric bolometer, but its optimum performance occurs at about 50 DEG C. The compositional modifications described enable this optimum temperature to be adjusted, to match a particular application, without loss of peak sensitivity. One modification provides the substitution of a bismuth/potassium mixture for a proportion of the lead to lower this optimum temperature. for example, to achieve the best performance at typical ambient conditions, near 20 DEG C. A second modification increases this temperature by substituting niobium for a proportion of the tantalum. This allows detector operation over a wide range of external temperatures with stabilisation by heating, but without any requirement for cooling. Both compositional modifications provide for a valence balance between substituting and substituted elements. This ensures that the electrical resistivity of the material is not lowered significantly by either modification. This is of particular importance for low noise, dielectric bolometer detectors. The material may be prepared by hot pressing/sintering methods or by thin layer deposition methods.
