Patent GB-2265915-A (GB)
Title: Bending and shaping MDF
Inventor: PRATT DAVID PIERS ROSS
IPC: B27K5/00
Filed: 1993-04-02
Abstract: MDF, or medium density fibreboard, is a common replacement for wood. It is usually manufactured as flat sheets, and is a stiff, rigid, inflexible material that is difficult to bend into the sort of complex shapes often required. It has now been found that by impregnating MDF with ammonia (used in anhydrous - that is to say, dry gaseous - form) the MDF can be made relatively plastic, and in its plasticised state can quite easily be pressed or bent into almost any shape required.

Title: External compensator of current transformers
Inventor: XU QIFENG
IPC: G01R15/18
Filed: 1993-08-02
Abstract: Nominal ratio and phase angle error between the fundamental component of current in the primary and the secondary of a Current Transformer Tn is due to its magnetising current, which is a non-linear function of primary current and burden Z2n. Based on the principle of physical similarity a specially designed model T1m (a small CT) which has the same magnetisation characteristics as the CT to be compensated is wired in the secondary circuit of this CT. The excitation current is obtained from the model and sent to the burden Z2n of the main CT so that its errors are compensated. It is suitable for new CT's and for CT's already installed in power systems. The model T1m is associated with an active zero magnetic flux sensor including a second transformer T2m and a high gain amplifier supplying a compensating current to burden a load Z2n of the main current transformer. <IMAGE>

Title: Metal sheet structures;permanent shuttering
Inventor: GALLOCHER STEWART
IPC: E04B2/86
Filed: 1994-12-21
Abstract: Metal sheet (10) is folded to form a hollow body (11) which is elongate and of constant cross-section along its length. The cross-section has a first face (11C) which defines a re-entrant profile and a second face (11A) containing the edges of the sheet (10) which defines a protrusive profile. The re-entrant and protrusive profiles are geometrically similar which enables adjacent similar sheets to be interlockingly engaged to one another, e.g. for use as permanent shuttering for a concrete wall as in Fig.2. <IMAGE>
Patent GB-2288346-A (GB)
Title: Machine for shredding brush
Inventor: BRAIN HENRY
IPC: B02C18/24
Filed: 1995-03-16
Abstract: A wood shredder (1) has a flywheel (22) mounted on an axle (10), the flywheel carrying L-section paddles (24) which in use urge brushwood fed down a feed chute (30) against the cutting edge of a knife (28). Because there is a flywheel the machine rotates at much slower speeds than conventional machines, and this results in there being less noise produced by the shredding machine. Furthermore, because the cutting blade is stationary it is easier to maintain. The axle (10) is usually connected in use to the power take-off of a tractor. The cutting machine usually has a support frame (16) which has a three-point linkage (40). <IMAGE>

Abstract: Anion-exchange materials having high affinity for plutonium anions such as plutonium (IV) and technetium anions such as pertechnetate are highly divinylbenzene-crosslinked polyvinylpyridine resins exhibiting a macroreticular bead form, which have been quaternized to contain a substantial amount of 1-alkyl-pyridinium groups wherein the alkyl group has 4 to 8 carbon atoms. The inventive resins can be used in preferred processes for recovering plutonium and/or technetium anions from aqueous mediums, for example nuclear waste streams or groundwater related to civilian or defense-related nuclear operations.
Patent GB-2304226-A (GB)
Title: Method for discriminating between different types of optical disk
Inventor: JEONG JEONG-JOO
IPC: G11B19/12
Filed: 1996-06-28
Abstract: Optical disk type in a machine capable of playing a range of types is determined by estimating disk thickness and/or track pitch. A thickness value is obtained by moving a laser pickup (6, figure 1) towards the disk at constant velocity and measuring the time taken to reach the focusing error minimum point. Track pitch is estimated by moving the pickup at constant velocity across the disk and finding the tracking error minimum points. The method reduces the lead in time between insertion of the disk and the start of reproduction.
Patent GB-2306661-A (GB)
Title: ECG Pace Pulse Detection
Inventor: HERLEIKSON EARL C
IPC: A61B5/366
Filed: 1996-08-06
Abstract: A flexible ECG monitoring system using pace pulse detection includes a portable monitor (102) that can be worn by a patient (120) or connected to a docking station (104). Tile portable monitor (102) includes an A/D converter and a digital signal processor. ECG signals are digitized and the digital signal processor derives a signal that is an estimate of the slope of the ECG signal. Pace pulses are detected by processing the slope signal, including use of a threshold that is dynamically updated based on the recent history of the slope signal. In particular, a pace pulse is detected when a positive slope which has been identified as exceeding the threshold is measured within a particular time of a negative slope occurring, which also exceeds the threshold. Detected pace pulses are removed prior to certain ECG filtering and reinserted following such filtering.
