Patent GB-2246718-A (GB)
Title: Fluid control apparatus
Inventor: DYSON EDWARD HUGH
IPC: F04B43/12
Filed: 1990-07-06
Abstract: A fluid control apparatus (50) which may be used for kidney dialysis comprises a blood delivery line (51) for delivering blood from a patient to one side of a dialyser (53). Blood is returned to the patient via line (56). An occlusive peristaltic pump (60) is arranged to drive fluid, from a dialysate supply (80), to another side of the dialyser (53), via line (61). The one side and the other side of the dialyser are separated by a filtration membrane. An occlusive peristaltic pump (65) is arranged to drive fluid from the dialyser (53), along line (62), to a waste vessel (66). A fluid line (70) communicates with the line (62), a pump (71) being arranged to drive fluid therealong to a filtrate collection vessel (73). Occlusive pumps (60, 65) are mechanically linked to pump fluid at the same rate. In use, a blood is pumped in lines (51, 56) and fluid is circulated by pumps (60, 65) to and from the dialyser. In this arrangement, no net flow of fluid passes from the blood side of the dialyser (53) to the other side. A net flow of fluid across the filtration membrane may be achieved by pumping fluid to vessel (73) using pump (71). In this case, fluid flows across the dialyser (53) from the patient in dependence upon the volume of fluid removed by pump (71). Thus, volumetric control of fluid removed from the patient may be achieved. Alternatively volumetric control of removed fluid can be achieved only by controlling the difference of speed of rotation of pumps (60 and 65) and collecting the resulting ultrafiltrate. The apparatus may be of general use in filtration or for dialysis treatment. The apparatus may be modified so that haemofiltration may be effected.

Title: Panoramic imaging system
Inventor: BAUMGARTEN KLAUS
IPC: H04N3/08
Filed: 1990-10-08
Abstract: Vertical and horizontal swivels 4, 6 enable a camera 2 of relatively narrow field of view, e.g. 3 DEG  x 2 DEG , to cover a wide field, e.g. 60 DEG  x 30 DEG ; successive narrow views 26i...26x are transmitted to a memory at positions corresponding to the camera direction and reproduced therefrom in corresponding positions on a display screen, for example as four stacked strips of joined narrow views, each strip 3 DEG  high and 15 DEG  wide (Figure 1B). A second screen may show a close-up of one narrow view. If the camera is in a moving aircraft or ground vehicle, absolute displacement of views may be prevented by control of the swivels in response to signals from fixed-spaced orientation detectors. Residual stabilisation errors may be detected by correlation of corresponding views of successive sweeps, and corrected electronically by image displacement. The swivels may displace the camera and/or a mirror in front of the camera. The memory may be a digital frame store or involve afterglow.   <IMAGE>

Title: Intersection solution method for drill bit design
Inventor: FISCHER JOHN G
IPC: E21B10/43
Filed: 1991-02-07
Abstract: A process for distributing cutters along the profile of a drill bit and a drill bit produced by such a process is provided by which at least during one stage of bit design the cutters are distributed in a manner providing that each cutter traces a path of predetermined area. Two methods for determining that area are presented. The cutter distribution process provides for accurate cutter placement by taking into account each cutter's radial distance from the center line, respective placement along the profile, and intersection with other cutters. The placement of each cutter element along a conventional bit profile is determined by defining the bit profile in terms of a continuous line of alternately facing acute isosceles triangles the legs of which are equal to the cutter radius. The development of this geometry is achieved by the mathematical solution of the intersections of circles with lines and of circles with circles. <IMAGE>

Title: Ceramic particles
Inventor: DAVIES PETER
IPC: C01B21/06
Filed: 1991-09-09
Abstract: The invention provides a method of making a concentrated supply of ceramic particles which are readily wettable when added to an aluminium-based melt. The method companies forming a dispersion of ceramic particles (preferably titanium diboride) in a metal melt (preferably aliuminium) such that the ceramic particles are thoroughly wetted by the melt, solidifying the melt, and extracting metal from the solidified dispersion (preferably by caustic soda treatment where the melt comprises aluminium). The resulting supply of ceramic particles can then be dispersed in an aluminium-based melt under easily producible conditions (generally under ambient atmosphere, and at less than 1000 degrees C), with full wetting of the particles. The preferred method of producing the initial dispersion is by an in situ reaction of titanium and boron, which are preferably formed by reaction of aluminium in the melt with salts containing boron (preferably KBF4) and titanium (preferably K2TiF6).
