Patent GB-2183850-A (GB)
Title: Fluid flow sensor
Inventor: HAYNES JOEL ERWIN
IPC: G01F1/20
Filed: 1986-10-23
Abstract: A fluid flow sensor comprises a housing having a fluid inlet (2) and a fluid outlet (3), a measuring chamber (4) in the housing (1) connected at opposite ends to both the fluid inlet and the fluid outlet, a member (10) in the chamber, movable between opposite ends of the chamber, and a valve assembly (15) operable solely by fluid pressure for controlling fluid flow through the housing. The valve assembly (15) is movable between a first position in which it cuts off one end of the chamber from the outlet so that fluid in that end of the chamber acts on the movable member to urge it to the other end of the chamber, and a second position in which it cuts off the other end of the chamber from the outlet so that the member is urged back in the opposite direction. The member oscillates back and forth at a rate proportional to the flow rate. The sensor can be used with fluids having a wide range of viscosities including petrol and syrup for milk shakes and icecream dispensers. <IMAGE>

Patent GB-2226889-A (GB)
Title: Circuit testing
Inventor: MCKEON ALICE
IPC: G01R31/28
Filed: 1990-01-08
Abstract: An analogue circuit or unit under test (34) is tested utilising automatic test equipment (30) and an interface unit (35) to apply stimuli to the circuit (34), the stimuli including supply potentials. A computer (32) analyses the circuit (34) as a network of nodes and modules to deduce a set of ranges of values at selected nodes, the ranges being determined from the set of the stimuli and a resultant set of test measurements, taken from nodes of the circuit by means of the interface (35) and automatic test equipment (30), taking into account tolerances in the stimuli, the measurements and the nominal parameters of components of the circuit. If there is inconsistency among the derived ranges the computer (32) treats as potentially faulty any module which could remove the inconsistency if the constraints imposed by that module were suspended. The computer (32) controls an iterative, hierarchical process involving repetition of the sequence of steps using different sets of stimuli and/or measurements and/or different analyses of the circuit into nodes and modules, in particular with analysis in terms of successively smaller modules. In this way, the location of faults can be progressively narrowed down and corresponding output information can be given in a device (40) such as a VDU or printer.

The color image signal controlled by this controller (40) is displayed on a display panel (42) having a plurality of discharge paths two-dimensionally arranged. Each discharge path displays one of a plurality of predetermined colors. The display controller (40) permits those discharge paths of the same color of the display panel (42) to be connected to the same ballast, and performs lighting control through time-division of a lighting time of these discharge paths of the same color. <IMAGE>

Title: Monitoring condensate traps
Inventor: CARMICHAEL RICHARD Q
IPC: F16T1/48
Filed: 1990-05-03
Abstract: A condensate trap (such as a steam trap) is monitored by means of a sensor chamber 4, disposed upstream of the trap. The chamber 4 is divided by a partition 10 pierced by a pressure equalising aperture 16, into inlet and outlet compartments 6, 8. A level sensor 18 extends into the inlet compartment 6 and a thermoelectric (eg Peltier effect) generator 20 is disposed on the wall of the outlet compartment 8. In use, the status of the steam trap is displayed as a function of the temperature and level of condensate in the monitor, electrical power for operating the monitor being generated by the thermoelectric generator 20. The monitor is thus self-contained and requires no external power source. In alternative embodiments, the peltier generator 20 may be located in the steam trap or the level sensor may comprise a float carrying an actuating element which operates switches. <IMAGE>
