Patent GB-262958-A (GB)
Abstract: 262,958. British Synthetics, Ltd., and Higgins, E. B. Dec. 28, 1915. Arylamides of 2 : 3-oxynaphthoic acid are prepared by the interaction of 2 : 3-oxynaphthoyl chloride and aromatic amines not containing electronegative substituents in the presence of a weak alkali and in one of the following ways : -(1) the amine is mixed with a weak alkali and sufficient water to form a paste and the 2 : 3- . oxynaphthoyl chloride, either solid or in solution or suspension added with vigorous mixing; (2) the amine, oxynaphthoyl chloride, and weak alkali are mixed and then water added; (3) the mixture of the amine and oxynaphthoyl chloride is added slowly to water. The reaction temperature should not exceed about 60‹ C., otherwise internal condensation of the 2 : 3-oxynaphthoyl chloride may occur; the latter should also be free from thionyl chloride, so that when it is prepared from thionyl chloride and 2 :3-oxynaphthoic acid the latter should be used in slight excess which passes unchanged through the reaction. According to examples (1) aniline or #-napthylamine is mixed to a paste with sodium bicarbonate and a little water and a benzene solution of the oxynaphthoyl chloride added; (2) sodium bicarbonate, aniline or alpha-naphthylamine, and the oxynaphthoyl chloride or a benzene solution thereof, are ground together and water added gradually to the mixture: (3) o-toluidine or o-anisidine is mixed with the oxynaphthoyl chloride or a benzene solution or suspension thereof, and the mixture added to a paste of sodium bicarbonate and water.

Title: Process for the preparation of carrier-bound proteins
IPC: C12N11/08
Filed: 1972-06-07
Abstract: 1357861 Carrier-bound proteins; polymerizing enzyme compounds BOEHRINGER MANNHEIM GmbH 7 June 1972 [9 June 1971] 26556/72 Headings C3H and C3P Carrier-bound proteins (enzymes) are produced by reacting the protein in aqueous solution with a compound containing at least one epoxy group and at least one further functional group capable of producing a bond with a carrier substance and then reacting this further group with the carrier substance. The carrier is preferably produced within the aqueous reaction solution by the polymerization of a monomer or monomer mixture. Thus, the reaction of the protein with the epoxy compound may take place in the presence of a polymerizable monomer, whereafter polymerization is carried out with the polymerizing in of the epoxy compound-protein product. Alternatively, the polymerizable monomer may be added and polymerized after the epoxyprotein intermediate has been formed. Preferred epoxy compounds for use in conjunction with olefinically unsaturated monomers are of the general formula wherein R 1  is a mono- or poly unsaturated alkenyl radical, an alkenyloxy radical or an unsaturated acyl radical, preferably one containing a CO group conjugated with a carboncarbon double bond, R 2  is a hydrogen atom or a lower alkyl radical (up to C 4 ) and n is 0, 1 or 2. Many compounds are particularly mentioned. Preferred monomers are the water-soluble derivatives of vinyl alcohol, acrylic acid and methacrylic acid including the amides, nitriles and esters of acrylic and methacrylic acid. The carrier may be crosslinked either during its formation or after its reaction with the epoxy compound-protein product. The examples are directed to the preparation of carrier-bound proteins from the following constituents: glucose oxidase, uricase or hexokinase; acrylic acid - (2,3 - epoxy - propyl ester), 1 - (allyloxy)- 2,3 - epoxypropane or 1,2 - epoxybut - 3 - ene; acrylamide (carrier substance); N,N<SP>1</SP> - methylene - bis - acrylamide (crosslinking agent); and 3 - dimethyl - amino - propionitrile and ammonium peroxydisulphate (polymerization initiator combination). The polymerizates are forced through a metal sieve of 0À5 mm. mesh size and washed to remove adsorptively bound enzyme.

Title: Method and apparatus for handling continuous strands and the like
Inventor: SLAYTER GAMES
IPC: D01D10/04
Filed: 1955-09-16
Abstract: In the manufacture of a bulky, looped, continuous, flexible, filamentary strand, a strand of continuous filaments is fed longitudinally to, and is deflected before reaching, a looping zone wherein the strand is interrupted by relative transverse movement of a strand-engaging member so that serially connected loops of strand are formed by and become suspended on either side of the member and the looped mass is continuously removed from the zone.  As shown in Figs. 1, 4 and 5, filaments 21 drawn from streams emerging from nipples 22 in a melter 23 optionally receive an application of binder or coating material from a spout 25 and are formed by a guide 24 into a strand 20 which passes through driven pulling wheels 27 and 28. The strand 20 impinges on, and is thereby opened by, a deflector plate 128, then projects into the path of a rotary peg-spinner 50 comprising <PICT:0824223/IV (a)/1> <PICT:0824223/IV (a)/2> <PICT:0824223/IV (a)/3> <PICT:0824223/IV (a)/4> <PICT:0824223/IV (a)/5> a shaft 124 mounting a disc 123 carrying pegs 55 which are straight and parallel to the axis of rotation of the spinner or have their tips curved inwards towards such axis and which form the filaments into randomly varying loops and entanglements, Fig. 2 (not shown).  The looped material is concentrated into a "roving," as at 76, which is withdrawn through an adjustably mounted gathering eye 65, as by means of pulling and winding mechanism 80 or a stapling means or "chopper" (not shown).  As shown in Fig. 6, the spinner rotates about a hollow axle 132 through which a strand, web, cord, filament, ribbon, thread, rope, sliver or roving of natural fibres, e.g. jute, hemp, cotton, flax or regenerated or synthetic materials, e.g. a thermoplastic film, is introduced and forms a constituent or core of the "roving" 76; the filaments may be sprayed with a liquid or liquid carrier from a head 137 and/or the "roving" may be coated with a natural or synthetic wax, resin, glue or size and heated as by lamps 140. In a modification, Fig. 7, the entangled loops of a strand 20 are withdrawn through the axle 132.  Specification 824,224 is referred to.

Title: Improvements in and relating to the moulding of soap
IPC: C11D13/16
Filed: 1931-09-24
Abstract: 394,365. Casting soap. BAKER PERKINS, Ltd., Hythe Road, Willesden, London, WEBB, E. T., Westwood Works, Peterborough, and A N C I E N S ETABLISSEMENTS A. SAVY, JEANJEAN, ET CIE, Avenue Dubonnet, Courbevoie, Seine, France. Sept. 24, 1931, No. 26642. [Class 87 (ii).] In the moulding of soap by an endless chain of moulds travelling under filling means and through a cooling chamber, the moulds are preheated approximately to the temperature of the liquid soap, and preferably are formed with four hinged sides which are opened out to release the moulded cakes, and in addition the cooling is effected gradually and progressively to prevent sudden chilling of the cakes, while the filling may take place in a vacuum chamber. In the plant shown in Fig. 1 the moulds 10 pass over burners or electric heaters 14 or alternatively through a hot-air chamber, and are filled by the nozzles 16. In the baffled cooling-chamber 18, air supplied by the fan 22 passes to the exit 21 in counterflow to the run of the moulds. At the discharging point the inverted moulds are opened and the cakes delivered to the conveyer 23. The pivoted mould walls are opened and closed by the combined axial and rotary movements of bars 27, Fig. 4, moved by fixed ramps sliding each pair of bars simultaneously in opposite directions. The sliding movement opens the end walls 25 through the engagement of collars with the pins 38, and in addition couples the projections 30 with forks 31 on the front and rear walls so that the subsequent rotation of the shafts by fixed pins opens these walls. A vacuum chamber may be provided to surround the feeding-nozzle 16 and may be flanked on either side with similar vacuum chambers operating at an intermediate pressure. Flexible strips 50 on the feeding chamber walls cooperate with the moving walls 39 between the moulds to provide these chambers. The feeding-nozzles 16 may be raised gradually by a crank 44 as the filling progresses. The moulds mav in some cases be formed with fixed walls and a movable bottom which acts as an ejecting-plunger.

Abstract: 425,241. Door-operating appliances. ADAMS, J. S., 3, Emerald Street, Bloomsbury, London. Sept. 28, 1933, No. 26737. [Class 65 (i)] A door closing and checking device comprises a spindle, carrying the door, rotatable in a cylinder in which slides a piston - carrying member having a pair of cam surfaces engaging a pair of anti-friction members carried by the spindle so that rotation of the spindle causes sliding of the spindle, a spring being provided to oppose motion in one direction and the usual valve-controlled passage being also provided. In the form shown, the cylinder 3 is fixed to the hinge post of the door and the spindle 6 is squared at the top for non-rotary attachment to a member fixed to the door. The lower part of the spindle carries a transverse pin on which is mounted a pair of rollers 4, Fig. 6, engaging between a pair of face cam surfaces 1<a>, 5<a> on a hollow member 1, the upper cam surface 1<a> being formed on an integral part of the member 1 while the lower is formed on a member 5 fixed in the lower end of the member 1. A piston 2 is fixed to the top of the member 1, and has packing 12 to prevent leakage of oil along the spindle 6. Rotation of the member 1 is prevented by keys 15 thereon engaging slots in a bearing cup 14 fixed in the bottom of the cylinder 3, so that rotation of the spindle 6 causes sliding of the piston along the cylinder, upward movement of the piston being opposed by a compression spring 7, bearing on the top of the piston, which returns the piston and closes the door. The cylinder 3 is filled with oil, and a byepass passage (not shown) in the cylinder wall connects the space above the piston to one of the slots in the cup 14, whereby oil can flow from one side of the piston to the other. A ball valve in this passage allows free flow of oil when the piston is moving upwards, but restricts the flow in the reverse direction, the resistance to flow being regulated by a screw preventing complete closing of the valve ; this screw is arranged horizontally, and has an inclined end engaging an inclined upper end of a vertical pin against the lower end of which the valve ball seats.

Title: Fluid-pressure servo-motor control valves
IPC: F15B13/043
Filed: 1954-09-15
Abstract: 795,237. Fluid-pressure servomotor controlsystems. EX-CELL-O CORPORATION. Sept. 15, 1954 [Sept. 21, 1953], No. 26745/54. Class 135. A slide valve 10 in a bore 20, which determines the fluid flow through passages 11, 12 to and from opposite sides of a ram 52, has four lands 14-17 and is positioned by control and supply pressures applied, respectively, to the ends Ac and As, the latter being half the area of the former due to an extension 18; a threelanded valve co-operating with a single control port, not shown, may alternatively be used. Fluid from a supply S traverses a passage 70, the centre of the bore 20, passages 19, 25, a porous metallic filter, and a passage 26 leading to the valve end As; the passage 25 also leads via restrictions 29, 30 and a passage 28 to the valve end Ac whilst a branch 40 from passage 28 conducts fluid through magnetic and porous metallic filters to a nozzle 27, the outflow from which regulates the control pressure. Discharge passages 22, 23 from the bore 20 lead to a reservoir or accumulator R, to which fluid from the nozzle returns via a restriction 32 or a relief valve, not shown. Fluid through the nozzle 27 is controlled by a flap 33 arranged as the armature of a polarized torque motor 34; the flap 33 is pivoted by a torsion spring 35 between two opposed polepairs 36, 37 supported by end plates 38, 39 intermediate which is a permanent magnet 41. Two differential motor coils 43, 44 are provided to magnetize the flap ends according to the current direction and hence to move the flap towards or away from the nozzle 27. The valve extension 18 engages the centre of a pivoted beam 45 which is urged against the extension by a spring 46, the outer end of the beam being connected to the lower end of the flap by a spring 48 which causes a force proportional to the slide valve deflection to be fed back to the flap 33, which force opposes that produced by the motor 34. Finaly adjustment of the flap is effected by another spring 50. The application of a signal current in the coils 43, 44 causes the flap to adjust the control pressure on the valve end Ac whereupon the slide valve 10 is deflected until the force of the spring 48 on the flap 33 balances the electrical torque on the latter thereby tending to relieve the control pressure and restore system balance: the deflected valve position being proportional to the magnitude and direction of the input differential current. If the slide is moved from its equilibrium position it will act on the flap 33 to correct the error and restore the equilibrium. The flap 33 may be replaced by a diaphragm or other non-pivoted member, now shown.
