The lid 3 includes a transparent window so that the position of the marker 11 can still be viewed with the lid shut.
Patent GB-2312255-A (GB)
Title: Cartridge seal
Inventor: CARMODY CHRISTOPHER JOHN
IPC: F16J15/34
Filed: 1996-04-20
Abstract: A cartridge seal for providing a seal between the rotatable shaft 1 of a centrifugal pump having an impeller 3 which is removably secured to the shaft 1 and a pump housing 5 in which the cartridge is in use located. The cartridge comprises a sleeve member 15 at one end of which a seal 51, 59 is arranged around the sleeve member 15, the seal comprising an axially outer rotating portion 59 which in use engages, and rotates with, the impeller 3 and an axially inner non-rotating portion 51. The sleeve member 15 is adapted to be secured to the shaft 1 for rotation therewith and against longitudinal movement relative thereto. The non-rotating and rotating portions 51, 59 are mounted for limited longitudinal movement relative to a ring 31 which is longitudinally fixed with respect to the sleeve member 15 and which in use abuts a shoulder 41 of the housing. The non-rotating portion 51 is biased away from the ring 31 by biasing means 57, whereby the distance between the shoulder 41 and the impeller 3 may be varied. This allows the cartridge seal to cater for machining variations in the dimensions of the shaft and impeller. If the impeller is nearer the housing 5 then spring 57 is compressed.

Title: Sludge thickening apparatus
Inventor: COLLINS ANTHONY WILLIAM
IPC: B01D33/067
Filed: 1996-04-23
Abstract: A sludge thickening apparatus 10 comprises a rotatable drum (12) formed from a wall 16. The wall 16 comprises a first section 28 onto which the sludge can be directed and a second section 30 downstream of the first section. The first section is either solid or defines apertures which are finer i.e. smaller than those defined by the second section. The apparatus 10 further includes feed means 22 i.e. inlet pipe to feed a sludge to be thickened to the drum (12). The inlet pipe 22 includes pumping means (21A), a flocculating tank 32 and flocculant supply means (35) (Fig. 4). The inlet pipe 22 is provided with a bend 24 to enable the sludge to be directed towards the wall 16 at feed region (26), via a feed head (27). The direction of motion of the wall at the feed region is the same as the direction of motion of the sludge at said region (Fig. 2). In an alternative embodiment these motions are in an opposite direction with respect to each other (Fig. 3). The second apertured region 30 is also provided with diverting means in the form of fins 36. The apparatus is used in sewage and other industries which require sludge to be thickened.
Patent GB-2301955-A (GB)
Title: Pre-heat circuit for a discharge lamp
Inventor: YANG THIEN SIUNG
IPC: H05B41/04
Filed: 1996-06-10
Abstract: The pre-heat circuit 8 comprises a series circuit of a PTC thermistor and a SIDAC high voltage bilateral trigger device connected in series with the filaments 6, 7 of a fluorescent or other discharge lamp 9. A capacitor C3 may be connected in parallel with the series circuit of the PTC thermistor and the SIDAC. In operation, the voltage across capacitor C3 builds up to the breakover voltage of the SIDAC to provide a current path through the PTC thermistor to heat up the lamp filaments 6, 7. Heating of the PTC thermistor subsequently causes the voltage across the lamp 9 to increase sufficiently to strike the lamp. The voltage across the lamp then falls below the breakover voltage of the SIDAC which therefore blocks to prevent current flow through the thermistor during lamp operation, thus increasing efficiency. Additional components (10, Fig.4) - such as capacitors, resistors and/or inductors - may be connected in series with the SIDAC and the thermistor for ideal conditioning of the pre-heat circuit current and voltage levels. The values of such additional components may be varied according to lamp size/current, required pre-heat time, and the current and voltage ratings of the SIDAC and thermistor.

Title: Testing cell designed to detect phase changes in a fluid mixture
Inventor: BEHAR EMMANUEL
IPC: G01N27/07
Filed: 1996-08-08
Abstract: A mixture containing substances susceptible to deposit formation or flocculation is introduced into a chamber 1a within a body 1 and the mixture is circulated in closed circuit by means of a homogenising turbine 8 driven in rotation by a motor 28 via a magnetic coupling 11,27. As a function of the pressure and the temperature, measurements are taken on the one hand of variations in the conductance of the mixture by measuring the impedance between a cylindrical electrode 8 and the body 1, and on the other hand of variations in the apparent viscosity of the mixture by measuring the driving torque applied to the turbine using a sensor 29. As shown, the chamber is defined partly by a piston 18 and the mixture is injected into the chamber from a tank 25 via a passage 22. Pressure is applied to the piston by a pump P and the displacement of the piston is measured by an optical sensor 32. The invention can be applied to the study of deposit formation conditions or flocculation of asphaltenes in petroleum crudes, for example.
Patent GB-2304444-A (GB)
Title: Safety device for a diver
Inventor: SMITH MICHAEL CHARLES
IPC: B63C11/26
Filed: 1996-08-19
Abstract: The safety device includes means for monitoring the breathing of the diver and causing release and inflation of a surface marker buoy 52 attached thereto by a line 54 if it detects he has stopped breathing. The monitoring means may cause release of a cover 60 of the device allowing the surface marker buoy to rise or the cover may be a simple friction fit pushed aside by the inflating marker buoy. The monitoring means includes a transducer 26 monitoring the pressure of gas breathed, or the flow of gas inhaled or exhaled, by a diver. Various forms of electrical and electro-mechanical logic circuits are described, each of which provides for the comparison over pre-set or pre-settable time intervals of measurements made of gas pressure or flow rate values with pre-set values or with earlier recorded values. The line has a breaking strain enabling a diver to be pulled to the surface by any associate or assistant on the surface. A radio beacon may be activated and a marker dye released when the buoy is deployed. Switches 32, 40, 42 are provided disabling operation of the device at less than a predetermined depth and allowing the diver to prevent and/or trigger operation of the device.

The saturation magnetization of the first magnetic film exceeds that of the second magnetic shield film. A method of manufacturing the head is also disclosed.
Patent GB-2312227-A (GB)
Title: A seal for a wellbore annulus
Inventor: BAUGH JOHN LINDLEY
IPC: E21B33/00
Filed: 1994-10-14
Abstract: A seal useful for high temperature and high-differential pressures, particularly in sour gas wells, is disclosed. The preferred embodiment of the seal (56) is an elongated member having features akin to a chevron-type seal (70) at, at least one end, coupled with at least one interference seal (64). A pocket (68) is created in between these two elements (70,64) which can trap atmospheric pressure, thereby enhancing the ability of downhole well fluids to compress the seal against a mandrel (10) for facilitating its installation in a liner bore. The additional structural rigidity provided by the variety of alternative designs presented overcomes the tendency of the chevron portion (70) of the seal to fail due to downhole fluid pressures, displacing the chevron portion (70) out of shape prior to its insertion into a liner bore.

Title: Release assembly for wire cutting apparatus
Inventor: YANKAITIS MICHAEL J
IPC: B21F1/02
Filed: 1998-05-29
Abstract: A release assembly for wire cutting apparatus. The present invention provides a release assembly for wire cutting apparatus which allows for dynamic alternation of the cut parameters. The release assembly allows for the length of the wire to be cut to be altered, allows for the biasing force to be increased or decreased to thereby reset the release assembly for a wide range of wire gauges, and allows for the stroke length to be altered to thereby either increase or decrease the cut frequency. By allowing these parameters to be dynamically altered, and therefore by not requiring the machine to be shut down with each alteration, the present invention provides for a wire cutting machine which is more efficient and which is able to produce a greater quantity of cut wires than has heretofore been possible with prior art wire cutting apparatus. The release assembly comprises a housing 50, plunger tube 48, gauge rod 44 and spring 98 which biases the plunger tube towards proximal end 66. Proximity switch 52 senses the movement of the plunger tube and transmits a signal to cutting mechanism 40.
