Title: A water trap for a respiratory airline
Inventor: HICKS RICHARD BANFIELD
IPC: A61M16/08
Filed: 1990-06-08
Abstract: A water trap for a respiratory airline comprises a top 10 and base 20 the respective openings of which mate when they are releasably connected e.g. by a bayonet-joint. The opening of the top 10 is partially spanned centrally by a disc 15, leaving an annular pathway for water around the periphery of the disc. A resilient annular sealing member 18 connected at its outer periphery to the top 10 makes sealing contact with the disc 15 when the base 20 is removed, but when the base 20 is connected to the top 10 the upper periphery 19 of the base raises the sealing member 18 to allow water to fall from top 10 and be collected in base 20. <IMAGE>

Title: Spanner
Inventor: WALMSLEY ADRIAN VICTOR SURTEES
IPC: B25B13/08
Filed: 1991-01-23
Abstract: A spanner has a head comprising two jaws mounted on a handle, each jaw having an inner face opposed to and parallel to that of the other jaw. One of the jaws is reversibly movable in a direction at a small angle to the inner faces of the jaws so as to alter the gap between the faces, thus allowing free rotation of the spanner from one pair of opposed flats on a nut or bolt past one or more opposed pairs of apexes to another pair of flats. The spanner can thus re-engage the nut or bolt without having to be completely disengaged from the fastener. The movable jaw is preferably biased towards the operating position. <IMAGE>

Title: Generating elliptical objects
Inventor: OLIVE GRAHAM JOHN
IPC: G06T15/00
Filed: 1991-04-16
Abstract: Elliptical features are described in an image generator database in terms of an origin and major and minor axes defined by reference to a world or model space coordinate system. Image data is assembled for display by transforming the database contents into screen space and assessing for each of an array of sampling points distributed across screen space which features are to contribute to the portion of a final image in which the sampling point is located. In the case of elliptical features, data is transformed into eyepoint space and each sampling point is projected into eyepoint space to determine the point of intersection between a line drawn through the sampling point from the eyepoint and a plane defined by the axes. The coordinates of the intersection point in a coordinate system defined by the origin and axes, are used to determine whether or not the feature contributes to the sampling point.
Patent GB-2246036-A (GB)
Title: Clock recovery circuit
Inventor: YOSHIDA SHOUSEI
IPC: H04L7/02
Filed: 1991-06-26
Abstract: In a clock recovery circuit, a received APSK signal is sampled at (1) at a frequency N times higher than the transmitted clock in response to a first clock from a local clock source (2), and quantized into orthogonal digital APSK samples. An envelope of the orthogonal APSK digital samples is detected (3) and phase correlations are detected (5) between the envelope and locally generated orthogonal sinusoidal signals and averaged by a low-pass filter (6). The arctangent between the low-pass filtered orthogonal signals is detected (7) and applied to a subtracter (8). A threshold comparator (9) compares the subtracter output with N successive values. A digital V.C.O. (10) is supplied with an output signal from the comparator (9) to generate a sample clock fc at a frequency 1/N of the frequency of the first clock fs for sampling the digital samples from the A/D converter (1). A phase difference is detected by a phase comparator (12) between the second clock fc and the sample clock fc, the phase difference being applied to the subtracter (8) in which the difference between it and the arctangent is determined. The V.C.O. (10) controls the timing of the sample clock in response to the first clock fs in accordance with the output of the threshold comparator (9). The output of sampler (1) may be further sampled (13) and then applied to an interpolator. <IMAGE>

Title: Child-resistant closures for containers
Inventor: KING ROGER MILNER
IPC: B65D41/48
Filed: 1991-09-23
Abstract: A child-resistant closure comprises an inner closure part (50) which is rotatable and axially movable in an outer closure part (10). Leaf springs (24), ratchet ramps (64) and engagable castellations (22, 60) on the closure parts allow the closure to be screwed down easily, but require the outer part to be depressed axially to enable the closure to be unscrewed. The leaf springs also bias the outer closure part rotationally away from each angular position in which it can be depressed. At no time can the closure be left in a condition which would allow the outer closure part to be depressed immediately. The leaf springs have cross-sections tapering towards their free ends, and are radiused at the acute angle with the outer closure part. There are sixteen castellations on each closure part so that the closure does not have to be rotated through more than 22.5 DEG before it can be depressed. The closure and the container neck have four-start, fully engaging square-section threads. Once depressed, the closure can be unscrewed by rotation through about 90 DEG  or less. <IMAGE>

Title: In printed wiring board manufacturing use of waste etchant as copper ion sourcefor electroplating bath
Inventor: OTANI YASUAKI
IPC: C25D3/38
Filed: 1992-04-02
Abstract: To stabilise the plating film and to even the thickness thereof in the case where through holes of printed wiring boards are subjected to copper plating, there is used as a copper ion suply source for the plating bath a solution obtained from waste process etchant by neutralisation and dissolution of the resulting compound. Copper recovered from the etching waste liquor produced in the general manufacture of the printed wiring boards is supplied from a powder feeder 21 into a dissolution tank 23 to obtain a copper ion solution. For copper plating, a substrate 1 acting as a cathode is arranged facing anodes 28 within a plating tank 28. The dissolution tank 23 supplies the copper ion solution into a plating tank 28 to maintain at a predetermined value the concentration of copper ions of a plating solution 27. This allows the insoluble polar plate to be used as the anodes 28, which leads to a stable current density. <IMAGE>
