Title: Process of producing one-end-closed double pipe
Inventor: ITO MAKOTO
IPC: B21C23/20
Filed: 1993-04-26
Abstract: The process produces a one-end-closed double pipe (31) comprising an outer tube (32) and an inner tube (33). The gap between the tubes is closed at one end (34) of the pipe. The process comprises the steps of: providing a die (37, 38) having a molding cavity (39), a tubular punch (42), and a centre pin (40) disposed along the centerline of the punch; placing a piece of metallic material (35) in the molding cavity of the die; and pressing the metallic material with the tubular punch to force the metallic material to plastically flow separately into both a first space between the die and the tubular punch and a second space between the tubular punch and the centre pin to form the outer and inner tubes. The relative quantities of the separate flows of the metallic material into the first and second spaces are determined by the shape of the front portion of the tubular punch (42), thereby producing a desired ratio of the lengths of the outer and inner tubes. For example, the front surface (46, 47) of the tubular punch (42) may be tapered and/or side lands (43, 44) may be provided. These characteristics are adjusted to produce a smooth forging action. <IMAGE>

Title: An interpolator
Inventor: WALKER GAVIN ALEXANDER
IPC: H04N7/26
Filed: 1993-05-17
Abstract: An interpolator, for deriving output values representative of data points intermediate a set of values for reference data points at predetermined intervals, determines (at 42, 44) an increment value d for successive intermediate values as a fraction of a difference value derived by subtracting a value for a first reference data point of an adjacent pair of reference data points from a value for the second reference data point of the pair and derives (at 60 - 66) a plurality of respective interpolated values from the pair of reference data values, including at least one output value for a data point outside the interval between the adjacent reference data points. The interpolator finds particular application in the address generator of a digital video effects generator. For a 4-point interpolator, the prior art need to multiply the increment d by 3 is avoided. <IMAGE>

Title: Design and manufacture of utility poles in fibre-reinforced plastics
Inventor: HOSFORD GREGORY S
IPC: E04H12/02
Filed: 1994-12-02
Abstract: A hollow, step-wise-tapered, fibre-reinforced plastics utility pole 10 is designed by a computer-modelling technique that simulates applying resin-coated reinforcing strands over the outer surface of a mandrel. A plurality of test stations 26A - 26E are incrementally spaced from the tip portion 18 to the butt portion 22 of the simulated pole. The thickness-to-diameter ratio must be equal to or greater than an established constant at each station, and additional circuits of strands are deemed to have been applied as required. The stress resistance at each station is calculated to determine if it is acceptable. Whatever additional circuits of strands are necessary are then deemed to have been applied. The projected failure load in response to the deflection calculated to occur in response to the rated load at each station is calculated to determine if the actual loading to be applied to the pole in relation to the projected failure load at that station is acceptable. The acceptable stress is modified by a binary chopping routine until the relation of the projected failure load and the rated load differ by an acceptable amount. All tests are recalculated until no further changes are required. The pole may then be laid up on a mandrel, and the resin cured to complete the pole. The strands may be made of glass. <IMAGE>

Title: A low fat spread
Inventor: MAGUIRE JOHN
IPC: A23D7/005
Filed: 1995-10-23
Abstract: A low fat spread which has a relatively low stabiliser content is prepared using a margarine process from a fat phase which includes a fat liquid at room temperature and a fat firm at room temperature and an aqueous phase. The aqueous phase is dispersed in the fat phase to form a water-in-oil emulsion which is subsequently pasteurised and cooled to a temperature of 6 DEG C to 20 DEG C. The water-in-oil emulsion is then subjected to vigorous shearing in a high speed pin mixer at a mixer speed of approximately 700 rpm prior to packaging. By subjecting the water-in-oil emulsion to vigorous shearing, it has been found that the spread can be stabilised with a significantly lower level of stabiliser than is required for low fat spreads known heretofore.

Title: Diagnosing degradation of a limiting current oxygen sensor.
Inventor: MIZOGUCHI TOMOMICHI
IPC: G01N33/00
Filed: 1996-06-04
Abstract: An oxygen sensor, such as a solid electrolyte sensor, is operated in a limiting current region by application of a voltage V p and determination of limiting current I p which is used as a measure of air-fuel ratio of a combustion gas. To test for degradation of the sensor, a second voltage V a or V b which is outside the limiting current region, is periodically applied, and the peak value of the resulting current I a or I b id determined. The peak value is compared with a normal range, and when it falls outside the range, it is judged that the oxygen sensor is degraded. The sensor is heated, and the system produces an alarm light when degradation has occurred.
