Title: Wrap spinning
Inventor: HUNT ROBERT JOHN
IPC: D01H13/18
Filed: 1984-04-18
Abstract: A sliver 2 forming the core of a yarn passes through drafting mechanism 4, 6, 10, 12, 20, 22, and wrapping mechanism for wrapping the core with one wrapper yarn drawn from a package 26 mounted on a rotary hollow wrapping spindle 24 and a second wrapper yarn from a package 36 on a spindle 34. Delivery rollers 44, 46 pass the wrapped yarn through an enclosed guide 52 passing under an operator platform 58 to a winder 60. A stop motion comprises electronic detectors 72, 74 to detect the presence or absence of the wrapping yarn at each wrapping spindle and a further detector 76 which monitors the thickness of the yarn. In the event of a broken or missing yarn component, these detectors:   (i) remove the drive to the back feed roller 6 of the drafting mechanism to stop the feed of the sliver 2; (ii) disrupt the forward travel of the yarn to the winding spindles by operating a cutter 42, and   (iii) dis-engage the wrapping spindles 24, 34 from their drives.   <IMAGE>

Title: Metal working oils
Inventor: KUWAMOTO HIROSHI
IPC: C10N20/04
Filed: 1984-05-30
Abstract: A metal-working oil composition comprises (a) one or more lube-oil components selected from oils and fats, mineral oils and fatty acid esters; and (b) one or more water-soluble polymers selected from homopolymers of acrylic amide, copolymers of acrylic amide and other monomers, and salts of the homopolymers and copolymers, the molecular weights of which homopolymers, copolymers and salts fall within the range of from 1,000 to 1,000,000. The incorporation of the specific water-soluble polymer allows a lube-oil component to disperse stably as large droplets in water and hence, several advantages including thick and strong lubricating film suitable for use under severe machining conditions can be obtained.

Title: Coaxial line pulse-shapers
Inventor: JILBERT PHILIP HARVEY
IPC: H01P9/00
Filed: 1986-04-04
Abstract: A pulse-shaper for generating very short pulses, eg down to 100 ps, from a fast input step-voltage, comprises first and second coaxial transmission lines 1, 2 having the same characteristic impedance z, and an open-ended stub coaxial transmission line 5 of one-way propagation-time  tau  connected between one or each pair of similar conductors (ie the inner and outer conductors respectively) of the first and second lines at one end of each line. As shown one such stub line is connected between the pair of inner conductors and the characteristic impedance is 2z; alternatively such a stub line, of characteristic impedance z, can be connected between each pair of similar conductors. When fed from a step-waveform generator G of output impedance z and into a load L of impedance z, a voltage pulse of half the step height and of duration 2 tau  is produced across the load. In practice, the several lines are arranged coaxially with one another to alleviate the effect of stray capacitance. A unit for producing pulses of selectable duration is described. <IMAGE>

Title: Testing digital audio systems
Inventor: GILCHRIST NEIL HENRY CHARLES
IPC: H03M1/00
Filed: 1986-05-02
Abstract: A low frequency test signal, e.g. 30 Hz, from a generator (10) is applied to a digital audio system (11) under test comprising an analogue to digital converter (12) and a digital to analogue converter (13). The analogue output is applied to an amplifier (14) and a high pass filter (15) which removes the test signal frequency and passes just the quantizing error and distortion components. These are passed through an amplifier (16) to a low resolution analogue to digital converter (17) providing error value samples to a computer (19). Each such sample is accompanied by a value from another low resolution analogue to digital converter (18) responsive to the unfiltered signal. These second values indicate the segment of the transfer characteristic of the system (11) under test. The computer (19) processes the inputs to ascertain the peak to peak amplitude of the quantizing error plus distortion signal for each segment of the transfer characteristic. In another embodiment (Fig. 3, not shown) a single high resolution analogue to digital converter is used and the computer performs digital filtering to form the error value samples and truncation to form the segment values. <IMAGE>

Title: Preparation of phosphonic acid derivatives
Inventor: ETHERINGTON TERENCE
IPC: C07F9/38
Filed: 1986-05-16
Abstract: Phosphonic acid derivatives are prepared by reacting 2-chloro-ethane phosphonic acid-bis-(2- chloroethyl) ester with phosphorus pentachloride. The resultant 2-chloroethane phosphonic acid dichloride may then be hydrolysed to produce 2-chloroethane phosphonic acid or subjected to dehydrohalogenation to produce vinyl phosphonic acid dichloride. The vinyl phosphonic acid dichloride may then be hydrolysed to form vinyl phosphonic acid. It is particularly preferred for the 2-chloroethane phosphonic acid-bis-(2- chloroethyl) ester to be a crude material produced by subjecting tris(2-chloroethyl) phosphite to thermal isomerisation. The phosphonic acid derivatives are particularly useful as plant growth regulators or flame retardants and the vinyl substituted derivatives can be polymerised for use in lithography and the manufacture of dental compositions.
