Title: Trackerball arrangement
Inventor: VEEL CHRISTOPHER JAMES
IPC: G06F3/0354
Filed: 1988-07-20
Abstract: A trackerball arrangement consists of a solid rotatable ball mounted within a housing and supported by a pair of orthogonal rollers 4, 5, which run in bearings. Rotation of the ball causes corresponding rotation of optical encoders attached to the rollers so that electrical signals are generated representative of the x and y rotation of the ball. The supports and bearings are prone to damage from vertical shocks received via the ball. To limit shock damage an additional resilient support allows the ball to move away from the bearings and absorb the shock. This resilient support consists of a rotatable wheel 10 on a pin 11 supported on a pair of guide rails 12. A pair of leaf springs 13 urges the wheel 10 against the trackerball.   <IMAGE>

Title: Identifying flow conditions (eg distribution of different fluid phases in a pipe)
Inventor: XIE CHENG-GANG
IPC: G01N27/22
Filed: 1988-08-31
Abstract: Unknown flow conditions are identified in terms of their similarity to simulated conditions for which computed sensor output values have previously been stored. Variations from standard flow patterns (eg core, annular and stratified distribution of fluid phases) can thus be identified. An array of eight capacitive electrodes 1-8 may be used, giving twenty-eight capacitive output values that can be combined to form a vector representative of actual flow conditions for comparison with a "fingerprint" vector representing standard flow conditions. <IMAGE>

Title: Grain refining of copper-based alloys
Inventor: NIXON R RICHARD CHARLES CAMERO
IPC: C22C1/03
Filed: 1989-08-18
Abstract: The invention provides a method of grain refining a copper-based alloy, especialy one having a beta phase as the primary phase on solidification, by arranging that a melt of the metal to be grain refined contains boron, and casting the boron-containing melt to produce grain refinement of the copper-based alloy. The invention is characterised by arranging that the melt which is cast also contains a reactive material (preferably calcium) which is more reactive with boron than boron is with iron. It has been found this makes the grain refinement process more tolerant of the presence of iron impurities, and that it also reduces the occurrence of hard spot defects in the cast product; and it has further been discovered that the incidence of hard spots can be eliminated, by casting from a sufficiently high temperature, e.g. from above about 1020 degrees C in the case of an alpha-beta brass. Grain refiners for practising the method are also disclosed.

Title: Sampling devices for stimulated radiation analysis
Inventor: MOULD HENRY MANIFOLD
IPC: G01N21/51
Filed: 1990-02-19
Abstract: A spherical sample cell bears an external inwardly specular layer defining a hollow imaging mirror 11D and an optical aperture 11E. The mirror acts as an integrator of both the exciting radiation for irradiating the sample and the resulting stimulated radiation to be analysed, the former entering and the latter exiting through aperture 11E. Integration resulting from multiple internal reflections of both radiations provides multifold increase in stimulated radiation compared to bare cells, which is of particular advantage in Raman spectrophotometry. Alternatively, the mirror may be provided in two complementary halves in a two-part cell-holder, in which case any conventional sample cell that fits within the mirror may be used. Spectrophotometers adapted for use with the sample cell or the cell holder as well as methods based on them are described. <IMAGE>

Title: Printing head
Inventor: IKEHATA TSUTOMU
IPC: B41J2/275
Filed: 1990-08-23
Abstract: A printing head which comprises solenoids (3) arranged in an annular array for driving needles (7) which are arranged in a zigzag array of two vertical columns (A, B). Solenoids corresponding to needles (7i) forming one of the columns (A) are arranged on a semicircle (C) of the annular array in the same order as that of the needles (7i) on the needle column (A), and two solenoids respectively corresponding to needles (723, 724) disposed at lower ends of the two needle columns (A, B) are designed to generate magnetic fluxes whose directions are the same to each other. During underline printing where these two solenoids (323, 324) are alternately energized, the magnetic flux generated by one of the solenoids never acts to increase an effective magnetic flux of the other solenoid at an initial stage of the excitation period thereof, so that the needle concerned reaches its forward most position at an appropriated time point, and the needle is rapidly restored, with its tip end prevented from being caught by the ink ribbon. After the forwardmost position being reached by the needle associated with the former solenoid, the magnetic flux generated by the latter solenoid never acts to increase the magnetic flux of the former, permitting rapid restoration of the needle. <IMAGE>

Title: Graphics accelerator area fill system
Inventor: NEAVE JOHN WALTER
IPC: G06T17/00
Filed: 1991-01-09
Abstract: A graphics accelerator system which provides improved image rendering speed. One significant bottleneck in such systems is the step of filling in a defined area, i.e. identifying every pixel in the interior of a given polygonal shape. One commonly used operation of this type is a "fill area set" operation. In a first mode of operation, the disclosed system very rapidly calculates the interior of a complex bounding polygon, by performing sequential XOR operations on shapes which are complementary to the various boundary elements of the polygon. An important advantage of this is that such XOR operations can be highly parallel. If two bounding polygons in the fill area set intersect, this mode of operation will not correctly identify points which are interior to both bounding polygons. In some applications this is generally recognized as acceptable; but in other cases this is not acceptable. Conventionally, where overlapping polygons must be precisely handled by fill area set calculations, winding number calculations are used to distinguish between pixels which are not in the interior and pixels which are doubly in the interior. In a second mode of operation, the disclosed system performs rapid fill area set calculations, even if winding number calculations are necessary. This embodiment differs from the first embodiment in that binary arithmetic operations are used instead of XOR operations, but this embodiment too permits the use of a very high degree of parallelism. The boundary elements of the bounding polygon do not have to be strictly limited to line segments, but may include curves. <IMAGE>

Title: Method and apparatus for the automatic assembly of venetian blinds
Inventor: KNIKKENBERG CARL ANDREUS
IPC: E06B9/266
Filed: 1991-02-28
Abstract: A venetian blind assembly machine in which slat material 20 is fed by rollers 22 onto a feed table 10, via a sensor 23 positioned upstream of a guide roller 23A. An adjustable end stop 28 is positioned downstream of ladder lacing stations 26, 27, each lacing station having a combined stop and lifting fork assembly 31. Each lifting fork assembly is positionable in any one of three different positions and can be retracted from a partially raised position either towards a lowered position or lifted into a further raised position. The sensor is adapted to interrupt operation of the feed rollers 22 when it senses that the slat material is buckled into or out of contact with the sensor, as a result of the leading edge of the slat material having been stopped by a fork assembly 31 or end stop 28. Alternative forms of sensor are disclosed. The sensor is preferably connected to a control system, whereby the occurrence of a sensor impulse and its count is predefined as either a signal to punch or a signal to cut off the slat material and to subsequently operate the lifting fork assembly 31. Guides 29 may prevent excessive downward bowing of the slat material between the stations. <IMAGE>

Abstract: A baker's oven has an oven compartment with a vertical drive shaft (16) supporting two pairs of carriers (18). The compartment is heated by electrical heating elements (27, 28, 30) each shaped to form an elongate U, with parallel arms extending across the compartment. The elements are arranged, by their respective spacing to the drive shaft (16), and by their spacing in each series of elements (27, 28, 30) so that if the carriers (18) are held at rest for some time in a first position and then rotated through 180 DEG  and held at rest for the same time in a second position, no part of the carriers (18) will be directly over, or directly under, an arm of a heating element (27, 28, 30) in both positions, to thereby avoid the likelihood of "hot spots", or overbaking in the bakery products supported by the carriers (18). <IMAGE>

Patent GB-2252553-A (GB)
Title: Plant growth medium
Inventor: WILSON FRANCIS NEIL
IPC: C05F5/00
Filed: 1992-01-06
Abstract: An alternative to peat as a plant growth medium is formed using a mixture of lignite, for example in the form of washed brown coal, together with a fibrous vegetable material, such as rice or peanut husks, coconut fibre, cocoa bean hulls, or sugar cane bagasse, which decompose slowly when exposed to bacteria. The lignite reduces the pH to an acceptable range, typically 7.5 to 4.5, and increases the cation exchange capacity of the plant growth medium. The fibrous vegetable material should be high in lignin, typically in excess of 60% by weight of lignin, and less than 15% of cellulose by weight of the dry matter. The plant growth medium may be made using a tumbling bed conveyor, or a hammer mill to produce a particulate material of appropriate size to encourage root growth and retain water.
