Title: Volume measurement in mixed fluid phases
Inventor: UNGERER PHILIPPE
IPC: G01F22/02
Filed: 1996-09-26
Abstract: A two-chamber containment cell in a thermostatically controlled enclosure is used to measure separately and at given pressure levels the volumes separately occupied by fluid phases before measuring the volume occupied by the mixture at the same pressure levels, so as to derive the excess volume (v E ) and the density of the mixture. By minimising an error function (F) which takes account of volume values such as the excess volume (v E ) or the density of the mixture and phase equilibrium data of the mixture such as saturation pressures (Psat), these data being determined in the cell, the coefficients of the equation of state linking the thermodynamic parameters of the mixture (P, V, T) can be determined to a high degree of accuracy and hence fined down for reservoir models, for example.

Title: Electronic caliper using a low power inductive position transducer
Inventor: MASRELIEZ KARL G
IPC: G01B7/00
Filed: 1997-05-09
Abstract: In an electronic caliper 100 which includes a slider assembly 120 mounted on an elongated beam 102 with first and second measuring jaws 108,110 projecting from the beam and cooperating with jaws 116,118 on the slider assembly, the position of the slider assembly on the beam being indicative of the distance between the measuring jaws, relative movement of the jaws is determined by an inductive read head 164 mounted on the slider assembly, and the magnetic flux produced and sensed by the read head is modulated by a set of elements 170 spaced along the beam. Alternatively the read head may be on the beam and the flux modulating elements on the slider. As shown the read head 164 includes a transmitter winding 180 and a pair of phase-displaced sinusoidal receiver windings 178,179 carried by a common printed circuit board 162. The flux modulators, which can be conductive flux disrupters and/or soft magnetic flux enhancers, are carried by the beam and modulate the magnetic fields produced by the transmitter winding 180. Thus, the receiver windings produce output voltages corresponding to the overlap between the modulators and the receiver windings. Signal processing electronics are connected to the read head and determine the relative positions of the jaws by monitoring the output of the receiver windings, the result being shown on digital display 138. The relatively insensitive nature of the low power induced current position transducer to industrial contaminants allows the caliper to function with improved reliability when operating in traditional work environments.

Patent GB-2328844-A (GB)
Title: Portable appliance power supply
Inventor: CORBRIDGE MARK
IPC: H04B15/00
Filed: 1997-09-02
Abstract: When a GSM cellular mobile radio telephone is operating in transmit mode with high transmitter power, too great a voltage and current is required to enable an RF power amplifier 10 to be satisfactorily supplied from a lithium ion battery 14. When the required amplifier power exceeds a threshold, the CPU of the telephone therefore activates a voltage boosting switch mode power supply integrated circuit 12 to charge a capacitor 13 from the battery 14. Transmission occurs in bursts, and the IC 12 is activated between bursts so that sufficient energy is stored in the capacitor 13 between bursts to sustain proper operation of the amplifier 10 during each burst. Disabling of the IC except when the phone is in a high power transmission mode ensures that the power taken from the battery 14 is minimised, and disabling the IC 12 during the actual transmission bursts ensures that interference is avoided.

Title: Terminal connectors
Inventor: RUSSELL GEOFFREY EDWARD
IPC: H01R12/58
Filed: 1998-08-29
Abstract: A terminal connector for use in mounting an electrical component such as the frame (6) of an inductance winding bobbin, on a printed circuit board (9), is formed by a pressing operation, such as from brass. The terminal connector comprises a first portion (8) in the form of a toothed finger, which may be inserted securely into a receiving aperture (7) of the electrical component, and a second portion (10) for insertion into the receiving aperture (16) of a printed circuit board (8). The second portion (10) is resiliently compressible in one cross-sectional dimension, and is initially oversized in relation to the dimensions of the aperture (16), such that on insertion of the portion (10) into the aperture (16), the portion (10) is radially compressed, and by virtue of the resilience of the material from which it is formed, maintains good contact with the soldered walls bounding the aperture (16). In this way it has been found that a connection may be made with the printed circuit board without the requirement subsequently to solder the terminal connector to the printed circuit board.

Title: Mounting ancillary units, eg pumps, on the lateral flange of a structural engine block
Inventor: PIERRO ENZO
IPC: F02B75/18
Filed: 1998-10-09
Abstract: The engine block 10, eg of a structural engine for a tractor, has a flange 12 which projects laterally from the rear end of the block 10. The flange 12 has apertures (22, 24, fig. 3) for mounting ancillary units, eg a fuel pump 14 and an hydraulic pump 16. Adapter plates 30,32 are bolted to the rear face of the flange 12 overlying the apertures. The surfaces of the adapter plates 22, 24 facing the apertures are machined to mate with the respective pumps 14, 16 which are disposed on the other side of the flange and secured to the plates 30, 32 through the apertures. The pumps 14, 16 can thus be mounted on the flange 12 without machining the front surface of the flange 12 which would be hampered by the structural ribs 18, 20 of the block 10 - the rearward facing surface of the flange 12 is readily machined at the same time as the gearbox-mating surfaces of the block. Different types of pump may be mounted by fitting different adapter plates and the axis of a pump may be offset from its aperture. The adapter plates 22, 24 may have extensions 40, 42 on their sides remote from the engine lateral flange 12 to accommodate an oil-fed bushing or an anti-friction bearing to support the projecting end of the pumps 14, 16.
