Title: Processing of resilient materials
Inventor: REES WILLIAM GERAINT
IPC: C08L97/02
Filed: 1996-07-22
Abstract: A chemically bonded medium is obtained from a resilient organic macromolecular material, in cut elongate of finely divided form (such as grass or peat). The material is dried (3, 4) under conditions permitting escape of water vapour, such that the dried material has a predominantly hydrophobic surface and a water content of not more than 10 % by weight; and then optionally flashed. The surface properties of the dried material are then equilibrated, under conditions inhibiting escape of water vapour and other volatiles, such that the predominantly hydrophobic surface is rendered predominantly hydrophilic. The product is then mixed (5) with a lignosulfonate, with application of heat in an amount sufficient to maintain the lignosulfonate in fluid form, such that the lignosulfonate forms a coating film on the surface. The lignosulfonate is caused to undergo partial polymerisation (6) (typically by heating and/or treatment with oxygen) on the surface of the dried material to produce a flowable, substantially non-resilient and non-tacky, chemically bonded medium. The bonded medium may be stored or shaped (8) under pressure to form agglomerates.

Title: Liquid ring pump with conical ports
Inventor: HAAVIK HAROLD K
IPC: F04C19/00
Filed: 1998-06-24
Abstract: A conically ported liquid ring pump 10' has one or more port structures 42,44 with cone angles ALPHA in the range from 15 degrees to 75 degrees. These cone angles are substantially greater than previously used cone angles (most commonly about 8 degrees). The large cone angles of this invention give the fluid flowing between the cone and the rotor 70 significant components of both radial and axial velocity. Large cone angles also allow the port structures 42,44 to be made axially shorter (P, fig 4), which has a number of important advantages such as shortening the unsupported length of the rotor shaft. These attributes of the present pumps are helpful for such purposes as allowing the length-to-diameter ratios of the pumps to be economically increased. In addition, the pumps of this invention retain many of the desirable attributes of conically ported pumps.

Title: Cylindrical beam former
Inventor: IINO HIROSHI
IPC: G01S15/42
Filed: 1999-01-28
Abstract: A transducer is constructed of a plurality of transducer elements which are arranged in multiple layers and columns forming as a whole a generally cylindrical shape. A scanning sonar employing the transducer thus constructed can be switched between horizontal scan mode in which a vertically focused beam having a narrow horizontal beam angle (high horizontal directivity) is steered around the transducer using all the transducer elements and vertical scan mode in which a horizontally focused beam having a narrow vertical beam angle (high vertical directivity) is steered in a vertical plane directed in a specified scan azimuth to find out the angle of incidence of a received signal. The horizontally focused beam is formed by using the transducer elements of specific columns centered on the specified scan azimuth. A vertical scan signal obtained in the vertical scan mode is multiplied by a chirp signal. A correlator provided in a succeeding stage converts the amount of Doppler shift into time data and determines the angle of incidence of the received signal.

Title: Infusion pump having automatic means for tube loading and opening slide clamp
Inventor: DANBY HAL
IPC: F04B43/12
Filed: 1997-02-27
Abstract: A slide clamp 895 has a closed position for clamping a tube (5, fig 17) and an open position. An infusion pump (10, fig 1) has automatic tube loading means that also drives crank (650, fig 19). On this crank rides bushing 802 which runs in raceway 813 to cause linear motion of traveller 815 and clams 820,830 which then close onto clamp 895, and draw it into groove 856, tube stops 844 retaining the tube, thereby opening the clamp 895. Shield 811 prevents accidental removal of the clamp 895. The infusion pump is then operable to pump fluid through the tube. This arrangement further assures that the clamp 895 is closed before the loading means allows removal of the tube. Locating pins 824A,824B combine with the asymmetry of the clamp 895 to orientate the clamp. Two optical sensors (fig 28) detect positions of clamp 895 in groove 856.
