Patent GB-2153074-A (GB)
Title: Multisensor
Inventor: STEWART ROBERT E
IPC: G01C19/574
Filed: 1984-11-16
Abstract: A multisensor of the vibrating- mass type comprises accelerometers (10, 12) mounted in parallel beam suspensions with their input axes (22, 24) substantially colinear. Forces are applied to the accelerometers through piezoelectric elements mounted to the suspensions to induce vibration so that coriolis rate information is included in the output of the system. Output circuitry discriminates between rate and linear acceleration information so that enhanced sensitivity to each parameter is obtained without confusion between coriolis and linear acceleration forces even when the frequency of linear acceleration is close to the modulation vibration frequency. Rate of rotation is sensed about axis (82). <IMAGE>

Title: Measuring or monitoring the level of liquid in a vessel
Inventor: ABBOT NEIL DAVID
IPC: G01F23/26
Filed: 1985-11-18
Abstract: In order to measure or monitor the level of liquid in a vessel there are provided first and second electrical conductors each extending between a first and a second level in the vessel. The conductors are electrically insulated from each other. The electrical capacitance between the conductors varies with liquid level and is a measure of the level of liquid in the vessel. In determining the volume of beer in a metal keg of which the walls are lined with electrically insulating plastics material, the capacitance is measured between the keg wall and the beer which is electrically conductive and in contact with the inlet/outlet spear. Apparatus for carrying out the method may be arranged also to measure the electrical resistance between the spear and the wall, this enabling the integrity of the lining to be categorised. The apparatus may operate electronically and store successive measurements for subsequent transfer to a computer. Electronic components are mounted in housing (1) having a collar 2 surrounding three spring loaded contacts (4). When the housing (1) is placed on top of the key a control contact (4) contacts the spear which acts as one of the conductors and the other contacts make contact with the side wall of the keg which forms the other conductor. <IMAGE>

Abstract: The irrigator or sprinkler for liquid or slurries shown has a rotatable boom 1 at the ends of which are angled regions 2. The angled regions 2 are directed on opposite sides of the longitudinal axis of the boom 1 to cause rotation thereof when effluent or water is pumped to the boom 1. The regions 2 may have rubber or the like nozzles 3 chosen so that larger pieces of effluent can be pumped therefrom. The boom 1 may be two lengths of galvanised or PVC 50mm pipe joined at the centre by a T-junction 4. The boom 1 is supported by an upper part 5 of an upstand 6. The upper part 5 can rotate relative to the wheeled frame 7 on which it is supported. The part 5 has on the periphery thereof at least one cam surface 8. In the example a single cam is shown. If varying travelling speeds are required then two cams on opposite sides of the part 5 can be included to increase the number of times the cam means operates per revolution of the boom 1 or the teeth on the ratchet wheel can be changed to adjust the speed of revolution of the boom. <IMAGE>

Patent GB-2211557-A (GB)
Title: Low drag peristaltic pump
Inventor: HOOD ROBERT GORDON
IPC: F04B43/12
Filed: 1988-09-28
Abstract: A nip is created in a resilient tube 16 by compressing the tube between a housing and a roller 20. The roller is rotatable about its own axis only so that the "nip" magnitude is stationary and the rotation of the roller acting on the tube at the nip volume forces fluid along the tube. The pump shown includes five driven rollers 20 spaced around the housing to define five stationary nips. The rollers are each coupled by a friction drive to a single central drive roller 18 so that the rollers 20 are driven simultaneously in the same direction. The housing has a removable lid (22, Fig 1) and the lid, housing and rollers define the nip at which uncontrolled deformation of the resilient tube 16 is limited in order to maximise pumping action, fluid flow rate and fluid pressures developed by the pump. <IMAGE>
