Abstract: The individual fibres of the inorganic yarn are in particular glass fibres, carbon fibres or metal fibres. Customarily, the fibres of the inorganic yarn are wrapped in another yarn, in particular a thermoplastic yarn, to form a composite yarn. This prior art method is very expensive. The invention, then, provides that the fibres of the inorganic yarn are passed together with the tensionless bundle of adjacent thermoplastic fibres through the intermingling zone of a gas jet for conjoint intermingling. The adjacent fibres interpenetrate the main fibre bundle. By means of subsequent softening and melting of the adjacent-fibre bundle the fibres of the main fibre bundle are bonded together to form a compact yarn. <IMAGE>

Abstract: A manifolded (6), multiple-pin die (9) apparatus and method processes potentially explosive material to form longitudinally perforated cylindrical pellets for use as gun propellants. A main entrance passage formed in mating manifold blocks gradually changes in cross-sectional configuration from circular to figure-eight (12), and then branches in a gently curved manner. The divergent branches formed then further branch in the same manner and feed circular cross-section passages leading to extruding dies wherein a series of die pins extend axially through a discharge passage. Each die comprises a central core member supporting an outer shell via radial ribs which are configured to form flow passages of hour-glass configuration. No change of flow direction in the entire apparatus exceeds fifteen degrees.

Title: Fluid flow control arrangement
Inventor: OXLEY MICHAEL DAVID
IPC: F16L37/127
Filed: 1989-06-19
Abstract: A control assembly 6 is described for controlling the flow of gas from a gas generating cartridge 21 into a gas bottle (not shown) to be charged and whose neck is inserted into a recess 16. The bottle cannot be inserted until a latch 44 has been pushed upward by means of a button 50 and until an operating lever (not shown) has been rotated sufficiently to turn a spindle portion 64 through 90 o  into a recess 66. The button is then released to latch the bottle and the operating lever closes a micro-switch in series with a second micro-switch which is only closed when the neck of the bottle is in recess 16. These micro-switches electrically energise an ignition unit in the cartridge 20 and gas generation starts. Gas passes through a sintered metal filter 28 and through a bore in a piston 78 and a pin 80 into recess 16, escaping around the outside of the gas bottle neck thus purging contaminants. The gas pressure moves piston 78 and pin 80 to the right and the distal end of the pin sealingly enters the bottle. Gas pressure opens a check valve in the bottle neck and charges the bottle. When peak pressure is reached, the check valve automatically closes. The operating lever then moves spindle portion   64 clockwise which opens a depressurising valve 82, allowing any still-present gas in manifold 74 to pass via bore 85 to the underside of piston 78, thus withdrawing pin 80. Button 50 can now be depressed to enable the charged bottle to be removed.

Abstract: A method for performing oversampled analog-to-digi­tal conversion of an input signal to generate a conversion result signal essentially free of systematic errors in accor­dance with the invention includes the steps of: performing oversampled analog-to-digital conversion of the input signal to generate a preliminary conversion result signal accompa­nied by systematic error, performing oversampled analog-to-­digital conversion of a zero-valued signal to generate a cor­rection signal essentially consisting of a corresponding sys­tematic error, and differentially combining the correction signal and the preliminary conversion result signal to gener­ate the conversion result essentially free of systematic errors. In a structural embodiment of the invention the sys­tematic error in an oversampled analog-to-digital converter (ΔΣ1) provided with a reference voltage (V REF ) that may be inconstant is suppressed by subtracting (SUB) from the conversion response the response of a similar oversampled analog-to-digital converter (ΔΣ0) to the reference voltage applied as its analog input signal.
