Abstract: 1471551 Thiophosphates COURTAULDS Ltd 14 Aug 1974 [15 Aug 1973] 39559/73 Heading C2P [Also in Division C3] Flame-retardant compounds have the general formula where R 1 , R 2  and R 3  (which may be the same or different) each represent an alkyl or alkoxyalkyl group having from 4 to 6 carbon atoms and each substituted with 2 to 4 bromine atoms. These compounds may be prepared by reacting an appropriate brominated alcohol (or mixture of such alcohols) with phosphorus trichloride to give a phosphite triester which is reacted with elemental sulphur to give the corresponding thionophosphate. The example illustrates the preparation of tris-(2,3-dibromo- 1-butyl)thionophosphate by this route. Alternatively the thionophosphate can be prepared from an unsaturated alcohol and then brominated. The compounds are used to render regenerated cellulose flame-resistant and are incorporated into the viscose spinning solution.

Abstract: 1484711 Automatic control systems MASCHINENFABRIK HEID AG 13 Sept 1974 [13 Sept 1973] 40102/74 Heading G3N In a method for correcting positional errors in a slide mounted cutting tool of a machine tool using a reflectable sensor, measurement is first made of positional errors in the mounting of the sensor, and then measurement and correction made of positional errors in the cutting tool. In this first stage, the slide is moved to a given position so that the sensor is engaged and deflected by one of a plurality of cams on the slide, the error in the deflection of the sensor being measured and used to eliminate positional errors of the sensor. These may be corrected by moving the slide whilst keeping the sensor stationary, moving the sensor whilst keeping the slide stationary, or by storing the measured error so as to use it in a numerically controlled system e.g. for a lathe, for correcting the second stage. In this second stage, the sensor is engaged and deflected by the cutting tool, the second error in the deflection of the sensor then being measured and corrected.

Title: Variable piezoelectric delay line
Inventor: SCHAFFT HUGO WILLY
IPC: H03H9/38
Filed: 1969-08-12
Abstract: 1,268,853. Acoustic delay lines. MOTOROLA Inc. 12 Aug., 1969 [26 Aug., 1968], No. 40264/69. Heading H3U. A delay line, Figs. 1, 2, comprises a piezoelectric crystal shaped as a tube 10, the mean diameter of the tube being less than one-half the wavelength of the highest frequency to be propagated. The input electrode structure comprises pairs of electrodes 12, 15 and 13, 16 provided on the outer and inner surfaces of the tube, the opposite end of the tube carrying corresponding pairs of output electrodes 18, 21 and 19, 22. The tube 10 is polarized circumferentially and the input signal from source 30 is connected to the electrode pairs 12, 15 and 13, 16 as shown, to produce an axial field therebetween, this axial field interacting with the circumferential polarization to propagate torsional waves through the tube. These torsional waves generate a corresponding output signal across the electrode pairs 18, 21 and 19, 22 connected to an output circuit 31 in a manner similar to the connections of the circuit 30. The delay time is variable by varying a D.C. supply 33 connected to a pair of electrodes 25, 26 provided on the outside surface of the tube, these electrodes co-operating with a cylindrical inner electrode 28 and functioning as a pair of seriesconnected capacitors. The field developed in the piezo-electric material by the electrodes 25, 26, 28 alters the velocity of propagation of the torsional waves and hence alters the delay. In a modification, Fig. 5, the piezo-electric crystal tube is axially polarized and the input signal circuit 43 develops a circumferential field by using a phase inverter 44 and connecting the input electrode pairs 37, 41 and 38, 40 as shown. In another embodiment, Figs. 6, 7, the piezo-electric crystal tube 50 is radially polarized and the input electrode structure, which produces a circumferential field, comprises electrodes 47, 48 on the outer tube wall connected to an input circuit 46 and a circular electrode 51 on the inner wall. The outer electrode structure is similar and comprises electrodes 53, 54 connected to output circuit 56 and an inner circular electrode (not shown). Control electrodes 57, 59, 58 correspond to electrodes 25, 26, 28 of Fig. 1. To prevent reflections from the crystal ends the ends of the tube 63 may be shaped as shown at 64, 65 in Fig. 8; alternatively, as shown in Fig. 9, the tube ends may have lead plating 93, 94. In a modification of Figs. 1, 2 (Figs. 10-13, not shown) a rectangular slab-shaped piezo-electric crystal is used equivalent to making a longitudinal cut through the cylindrical crystal and then flattening it out. In all the embodiments torsional waves are propagated between the input and output electrodes because the field produced by the input electrodes is orthogonal to the polarization field.

Abstract: 904,382. Pumping volatile liquids. CONCH INTERNATIONAL METHANE Ltd. Nov. 23, 1960, No. 40276/60. Class 102(2). In apparatus for pumping liquefied gases the pressure in a gas/liquid separation 3 is reduced either by refrigerating plant connected to the gas outlet 4 or by a compressor 5, whereby gas and liquid is drawn from a tank 2. In the latter case liquid is drawn from the separation by a pump 9 and passes through a heat exchanger 7 to an: outlet; the outlet from the compressor 5 is cooled in the exchanger 7 and returned to the separation through a throttle 13. The outlet from the compressor may also be connected to the tank 2 through a valve 15 to prevent negative pressure in the tank. Where the pressure is reduced by refrigerating plant the outlet therefrom is connected directly to the separation and the pump 9 delivers directly to the outlet. An inlet/outlet pipe 10 is connected to the vapour space in the tank. Reference has been directed by the Comptroller to Specification 869,080.

The alkaline medium may be sodium hydroxide of IN concentration and hydrolysis is continued for 4 days at room temperature, followed by neutralization to a pH from 6À5 to 7À5. Hydrochloric acid may be used for neutralization to a pH of from 7 to 7À5 or acetic acid may be used for neutralization to a pH of from 6À5 to 7. The crude precipitated glucopeptide may be dissolved in sodium chloride solution, the solution clarified by centrifuging, a precipitant then being added to the supernatant, removing the resultant precipitate, dissolving the precipitate in sodium chloride solution, clarifying the solution by centrifuging, adding alcohol to the supernatant and separating the final precipitate by filtering or centrifuging. The precipitant may be Cetrimide, trichloracetic acid or cetyl pyridinium chloride. Preferably the crude glucopeptide is purified by drying, mixing and pulverizing with cellulose powder or diatomaceous earth, charging a chromatographic column with the mixture, passing a solvent through the column, eluting the glucopeptide with a phosphate buffer at pH 7À8 and precipitating the glucopeptide with two volumes of alcohol, and filtering the purified glucopeptide. The purified glucopeptide may be dried, ground and screened.

In an extraction apparatus wherein material loaded into a series of adjacent receptacles is successively subjected to the action of solvents of varying strengths for the purpose of removing therefrom soluble substances the bottom of a receptacle is mounted on a cross member 2 which is attached to the lower edge of one of the side walls 4 of the container. The bottom is pivoted on the spindle 6 carried from member 2 and comprises a filter 8 which has associated therewith a deflector plate 10 for drawing away solvents which pass through filter 8 after having percolated through the miscella. In one embodiment of the invention the filter plate 12 shown in Fig. 2 is integrally connected for instance by welding to the bar 14 which forms part of the pivot. The bar is rotationally mounted beneath the lower edge of one of the side walls 4 of the receptacle and its axis of rotation is parallel with that lower edge. Only a small clearance between bar 14 and the lower edge of the wall from which it is pivoted exists and prevents raw material from passing therethrough during discharge. In Figs. 3 and 4, not shown, other modifications of this principle are disclosed.
