Title: Flame-Resistant Copolymers of Acrylonitrile
IPC: C08F20/42
Filed: 1968-06-28
Abstract: 1,182,035. Flame-resistant acrylonitrile copolymers. JAPAN EXLAN CO. Ltd. 28 June, 1968 [26 Sept., 1967], No. 31144/68. Heading C3P. Flame - resistant acrylonitrile copolymers, which are highly receptive to acid dyestuffs, comprise (a) 5-15% by weight of vinylidene chloride units, (b) 1-5% by weight of units of an amino-ester of the formula (where R<SP>1</SP> is H or methyl, R<SP>2</SP> and R<SP>3</SP> each is methyl or ethyl, and n is 2, 3 or 4) and (c) as the balance, acrylonitrile units. In a modification, 1-15% by weight of the acrylonitrile units (based on total copolymer units) are replaced by units of at least one neutral monomer (other than vinylidene chloride) copolymerizable with acrylonitrile. The optional neutral monomer component may be an alkyl, aryl or aralkyl (meth)acrylate, styrene, a-methylstyrene or other substituted styrene, a vinyl ester, e.g. acetate or formate, an unsaturated aldehyde or ketone, an alkacrylonitrile, or (meth)acrylamide or an N-substituted derivative thereof. The copolymers are prepared by polymerizing the corresponding monomers in the presence of a free radical-liberating catalyst or radiation, e.g. azobisisobutyronitrile, benzoyl peroxide, potassium persulphate, sodium chlorate/sodium sulphite or light radiation. Polymerization may be effected in bulk, emulsion, solution or suspension and can be performed batchwise or continuously. The copolymers can be dissolved in solvents such as dimethylformamide or y-butyrolactone to form spinning solutions. When the copolymer contains a relatively large proportion of vinylidene chloride units, the copolymer is suitably dissolved in an aqueous solution of an alkali metal, alkaline earth metal or ammonium thiocyanate having a concentration satisfying one of the following relationships:- (a) 5À3 # x # 7À4 and 47 # y #60; or (b) 7À4 # x # 12À0 and 0À8x + 41À1 # y # 60 where x is the content (per cent by weight) of vinylidene chloride units in the copolymer and y is the concentration (per cent by weight) of the thiocyanate in the aqueous thiocyanate solution. There may also be incorporated into the copolymers, during the course of polymerization or in the preparation of the spinning solutions, a conventional flame-resisting agent such as antimony trioxide or tricresyl phosphate.

Filed: 1961-08-30
Abstract: 967,586. Photo-electric chemical analysis control. C.C. HACH. Aug. 30, 1961, No. 31236/61. Heading G1A. [Also in Division B1] In the continuous automatic analysis of a fluid sample, the fluid sample and a test reagent each flow uniformly through metering passages at constant and predetermined heads respectively, to be mixed and dripped into a mixing cell wherein any reaction between the sample and reagent is detected. In the automatic analyser shown, a constant head of the fluid sample flowing in at 11 is established in overflow tube 27. The fluid sample then passes through filter 45 to be mixed with the reagent 12, flowing in through a metering capillary passage 31 and kept at a predetermined head in chamber 37 by float needle valve 39. The mixture then passes through a second metering capillary passage 21 to drip into a transparent cell formed of inner and outer tubes 50 and 51 for any reaction between the fluid sample and the reagent to be detected by photo-cell 64 receiving light from lamp 60 passing through the fluid mixture and colour filter 63, an indication being given on meter 10 or on a recorder,via plug 66. When used in a water softener process the reagent 12 may be EDTA (ethylene diamine tetra acetic acid) plus pH buffer and Erio Chrome Black T indicator and a red filter 63 may be used. The output of the photo-cell may be used to trip a relay or actuate an alarm. The apparatus is also suitable for detecting pH, chlorine on fluoride levels in water. The apparatus may be modified to perform automatic titration by the addition of a second reservoir tank and metering capillary tube to deliver an indicator to the titrant/sample mixture at a constant rate,the titrant being housed in chamber 33 with the float needle valve adjustable up and down an indicating scale by means of a nut working on a threaded rod rotated by a servomotor controlled by the output of the photo-cell, the float needle valve oscillating about the level of titrant giving the end point reaction in the cell 50/51, Fig. 2 (not shown).

Title: Invalid lift apparatus
IPC: A61G7/10
Filed: 1972-07-04
Abstract: 1376964 Invalid lifting devices J W SPIVEY 4 July 1972 [16 July 1971] 31254/72 Heading B8H An invalid lift apparatus comprises head and foot frames 16, 17 on which are mounted vertically movable supports 19, 20 respectively to which a rectangular lift frame 18 is attached, the frame 18 having a sheet 114 detachably secured thereto, on which a patient is supported. The support 19 is connected to a tube 32 which is slidingly mounted on a tube 26 mounted in the interior of the head frame 16, movement of the tube 32 and thus the support 19 along the tube 26 being effected by means of a cable 42 which passes about a movable pulley 36 mounted on the tube 32 and also about stationary pulleys 38, 40 on the head frame 16. Similarly the support 20 of the foot frame 17 is mounted on a tube 70 adapted to slide along a tube 66 under the action of the same cable 42 which is attached at one of its ends to a motor driven winch 82, passing first about stationary pulleys 68, 81 from which it passes to the stationary pulleys 40, 38 on the head frame 16 and then passes about the movable pulley 36 to extend vertically and pass through a boom 21 rotatably mounted on the head frame 16, the end 42a of the cable 42 which depends from the end of the boom 21 having a lift bar 22 attached thereto. When it is desired to raise the frame 18 relative to the frames 16, 17 the cable end 42a is anchored, for example to the boom 21 or head frame 16, the winch 82 is actuated to draw in the cable 42 which, because of the arrangement of stationary pulleys on both frames 16, 17 causes the pulleys 36, 78 and thus the tubes 32, 70 and supports 19, 20 to be raised. If it is desired to raise only one end of the frame 18 the other end of the frame is prevented from making vertical movement on actuation of the winch 82 by means of one of two drift pins (161, 159), Figs. 1, 4 respectively (not shown), which is inserted into its associated tube 66 or 26 just above the associated respective tube 70, 32. If both said pins are inserted into their respective tubes, operation of the winch 82 does not result in a raising or lowering of the supports 19, 20, instead the length of the cable depending from the end of the boom 21 is either increased or decreased. This is of advantage when it is desired to lift an invalid completely out of the bed B. In this case a further lift bar 22a is connected by cables 162 to the lift bar 22, Fig. 11, the bars 22, 22a being attached to the end and an intermediate part respectively of the sheet 114 which then sets as a sling to support the invalid on raising the bars by means of the winch 82, and as the invalid is lifted from the bed the boom 21 can be swung to either side of the bed to position the invalid over a wheel chair for example. Stabilizing frames (144, 152), Fig. 1 (not shown), having ground engaging castors (151) are mounted on the foot and head frames respectively, the head and foot frames each being provided respectively with castors 136, 138.

Title: Process for the emulsion polymerisation of unsaturated compounds and the polymers so produced
IPC: C08F2/24
Filed: 1950-12-27
Abstract: Olefinically unsaturated compounds which are practically insoluble or only partly soluble in water are polymerized to stable polymer dispersions in an aqueous phase in the presence of emulsifiers and of catalysts or catalyst systems which yield radicals in the aqueous phase by a process characterized by a flow of drops of the compound or compounds to be polymerized through the aqueous phase, the movement of the monomer drops with regard to the aqueous phase being caused mainly by the difference in the specific gravity of the two phases.  Preferably the monomer is p  allowed to separate as a layer distinct from the aqueous phase after its passage through this phase, the monomer being withdrawn from this separated layer and again passed through the aqueous phase, or a separate aqueous phase.  The aqueous phase may contain some preformed polymer when the process is initiated, and fresh water phase may be fed to the reaction space and the polymer dispersion drained off, feed and drain preferably being balanced. The Specification describes the preparation of polyvinylidene chloride, polyvinyl chloride, polybutadiene and of copolymers of vinylidene chloride with methyl methacrylate, methacrylonitrile, vinyl acetate or vinyl chloride, and of butadiene and styrene, and the process is also applicable to the preparation of polyethylene and of copolymers of butadiene and acrylonitrile. Ingredients of the aqueous phase specified are potassium and ammonium persulphates, sodium sulphite, sodium mersolate, potassium oleate, sodium bicarbonate and tertiary dodecyl mercaptan.

Title: Improvements in grinding or reducing apparatus
IPC: B02C19/00
Filed: 1939-12-05
Abstract: 535,123. Impact pulverizers TEXAS GULF SULPHUR CO., Dec. 5, 1939, No. 31549. Convention date, Jan 7. [Class 59] In grinding apparatus wherein the material to be ground, e.g. sulphur, is thrown by centrifugal force against impact or grinding surfaces, a vertical shaft 15 carries superposed spaced rotatable discs 18 alternately disposed with respect to superposed spaced fixed discs 17, and material fed to the uppermost rotatable disc from a feed shoot 43 is thrown against an impact or surface shell 16, falls on to the stator disc below, and passes by the central opening therein on to the next rotatable disc lower down; the stator discs are carried by the shell 16 and all these parts are gradually raised and then suddenly dropped under the action of a slowly rotated cam 2:1. The upper discs 17 carry upstanding bands or barriers 37, Fig. 9, and depending walls 32, the walls 32 being fitted with ribs 33 and with adjustable bands 35 of aluminium or other non-sparking material.

Title: Improvements in or relating to Solid Jacket Centrifuges
IPC: B04B1/14
Filed: 1967-07-10
Abstract: 1,180,627. Centrifugal separators. MASCHINENFABRIK BUGKAU R. WOLF A.G. 10 July, 1967 [20 Aug., 1966], No. 31724/67. Heading B2P. In a centrifuge for treating liquid suspensions, e.g. of a granular plastics substance, and comprising a drum having a peripheral discharge aperture defined between parts 3, 4 of the drum, the discharge aperture is opened or closed by means of a resilient sealing member which is actuated by liquid fed into an annular chamber 12 in the drum part 4 through at least one passage such as 14 or 16 and discharged through at least one outwardly extending passage 15 the cross-sectional area of which is smaller than that of the passage 14 or 16. The drum has a jacket consisting of a fixed part 2 secured by bolts 5 to the bottom 4 of the drum and an axially displaced part 3 which in its closed portion bears on a stop 2a to define a gap 11 with the bottom 4, the gap being of such width as to allow the passage of liquid but not of solids. The drum bottom 4 is mounted by means of webs 6 on a hub, and is provided with a central aperture, the edge of which is spaced from a closure cone 9 by means of a narrow gap 10. In the operation of a centrifuge having only one feed passage 14, the suspension is introduced into the separating chamber 8 with the jacket part 3 in the closed position. When the chamber is filled to such an extent that the liquid reaches the mouth of the passage 14, liquid will flow through the latter into the chamber 12 where under the effect of centrifugal force it will force the sealing ring 13 against the face 3a of the jacket part 3 so as to close the discharge aperture. A small quantity of liquid will flow continuously from the chamber 12 through the passage 15. Separated solids will accumulate in the chamber 8 and clarified liquid will discharge through the gap 10. When the level of accumulated solids has reached such an extent that the liquid flowing out of the gap 10 becomes turbid, feeding of further suspension into the drum is stopped and the centrifuge empties itself except for the accumulated solids. Since then less liquid enters the chamber 12 than leaves it, the ring 13 is no longer under pressure and opens the discharge aperture through which liquid still present in the chamber 8, i.e. in the interstices between the accumulated solid particles, is centrifuged out as it passes through the gap 11. When the remaining liquid has been centrifuged, the jacket part 3 is displaced upwardly by mechanism not shown to allow for discharge of the separated particles. Washing liquid may be introduced into the drum to wash the particles before displacement of the jacket part 3. The feed passage 14 may be dispensed with and the drum bottom 4 may be provided with a concave pocket communicating with the chamber 12 through one or more passages 16 so that the liquid on discharging through the gap 10 is caught in the pocket and part of it flows through the passages 16 into the chamber 12. Reference has been directed by the Comptroller to Specification 969,179.

Title: An improved method of, and apparatus for, operating self-synchronous motors and the application thereof to the measurement of rotational velocity
IPC: G08C19/06
Filed: 1936-11-19
Abstract: 477,114. Control of two motors. SUBMARINE SIGNAL CO. (LONDON), Ltd. (Submarine Signal Co.) Nov. 19, 1936, No. 31740. [Class 38 (iii)] [Also in Group XXXVIII] Periodic unidirectional pulses are used to operate interconnected synchronous motors, the pulses being supplied to the motor windings. The apparatus is used to indicate speed by delaying the pulse in a delay network. Shaft 1, the speed of which is to be indicated, is suitably geared to the rotor of transmitter 4. Periodically, the cam 5 closes the contact 6 so that an impulse passes to the rotors of both transmitter 4 and indicator 8. As the pulse is delayed by network 12, the rotor of transmitter 4 has moved through a distance proportional to its speed before the pulse reaches it and as the pulse causes the rotor of the indicator to assume the same position as the rotor of the transmitter, the pointer 9, connected to the indicator rotor, indicates the speed of shaft 1. A frictionally operated switch and a suitable relay enable the indicator 9 to move in the same direction irrespective of the direction of rotation of the shaft, a " backing " signal being operated when the shaft is rotating in one direction.
