Abstract: Foundry mould-sections are made from a refractory composition comprising 1/2 to 3 per cent of a thermo-setting resin and 1/2 to 5 per cent of a high temperature binder which becomes effective above 500 DEG C. to cause the refractory particles of the composition to bind into hard self-supporting structures, and to join an assembly of sections along their mating surfaces. Suitable refractories for the composition are zirconium silicate, zirconia, beryllium oxide, aluminium silicate, alumina, ground quartz, flint, silicon carbide, and mixtures thereof. Thermosetting resins quoted are phenol-urea-melamine-formaldehyde, alkyd and polyester resins and phenolic furfural.  High temperature binders are metal fluorides, with or without a boron compound such as boric acid or boric oxide, metal borates, silicates, or aluminates, ammonium phosphate, and compounds which yield phosphoric acid on heating, calcium sulphate zirconium oxychloride, magnesium oxychloride, and boric acid.  The addition of a liquid solvent for the resin ingredient to cause the individual refractory particles to become coated, permits the use of a refractory as fine as 325 mesh.  Without the solvent, refractory as fine as 150 mesh may be used.  Solvents quoted are acetone, ethyl alcohol, methyl ethyl ketone, and ethyl acetate.

Abstract: 1,262,611. Electromechanical delay devices. CHU ASSOCIATES Inc. 10 March, 1970 [6 Oct., 1969], No. 11381/70. Heading H3U. A device for compressing a frequencymodulated input pulse, e.g. in "chirp" radar, comprises a single-crystal rod 1<SP>1</SP> of YIG disposed in a cylindrical hole extending through a sphere 1 of polycrystalline YIG. The optically flat end faces of the rod 1<SP>1</SP> carry, respectively, an input shear-wave electrostrictive transducer 2 and an output longitudinal-wave electrostrictive transducer 4. The sphere 1 is uniformly wound with a solenoid coil 3 energized by a ramp generator 5, the entire structure being magnetized to saturation by a permanent or electromagnet N-S. The current I supplied by generator 5 has the waveform shown to produce a substantially uniform spatial magnetic field which varies in time. The generator 5 is turned on for each successive chirp pulse applied to the transducer 2 whereby at a certain value of the generator current I the magnetic field causes conversion of the elastic shear-wave to a spin wave and then to an elastic longitudinal-wave. The high-frequency components of the input pulse are delayed in the rod 1<SP>1</SP> more than the lowfrequency components whereby a compressed pulse is generated at the output transducer 4. Moreover, since the ratio of the propagation velocities of the longitudinal waves and shear waves is about two to one, the pulse compression factor is improved by a factor of about two.

Title: Improvements in and relating to the production of artificial threads, fibres, filaments and the like
Inventor: HANBY WILLIAM EDWARD
IPC: D01F4/00
Filed: 1950-05-10
Abstract: Artificial threads, fibres, filaments and the like are obtained by extruding a solution of a protein in di- or tri-chloracetic acid, or in a mixture of these acids, into a coagulant bath consisting of a liquid, or mixture of liquids, which is miscible with the acid of the spinning solution but is a non-solvent for the protein.  The protein may be milk casein, peanut protein, soya-bean protein, castor-bean protein or natural silk.  The coagulant liquid may be water, methanol, ethanol, or ether, or a mixture of these liquids.  The spinning solution may contain 5-20 per cent by weight of protein. After withdrawal from the coagulant bath, the threads may be stretched 100-300 per cent, preferably in the presence of hot water. In an example, a solution of lactic-casein in dichloracetic acid is extruded into water at 20 DEG  C.  The thread obtained is passed through a drier and then stretched in water at 70-100 DEG  C.  In another example, the protein used is peanut protein which has been extracted with sodium aluminate by the method of Specification 653,188, [Group IV (b)].  In another example, the spinning solution is prepared by stirring degummed natural silk in dichloracetic acid at 40 DEG  C. The solution is extruded into water at 20 DEG  C. and the threads are stretched 300 per cent after leaving the coagulant bath. Specifications 606,427 and 626,542 also are referred to.ALSO:Solutions of proteins in di- or tri-chloracetic acid, or in a mixture of these acids, are used for the production of artificial threads (see Group IV (a)).

Title: Improvements in the refining of hydrocarbons
Inventor: SPENCER DONALD
IPC: C07C7/171
Filed: 1958-04-11
Abstract: A process for acid-refining hydrocarbon fractions by removing non-aromatic unsaturated hydrocarbons and sulphur compounds comprises passing the hydrocarbon fractions and <PICT:0932938/III/1> sulphuric acid into a column provided with dispersion means and applying a pulsating pressure at one end of the column.  An example of a hydrocarbon fraction is crude benzole which may be refined to motor, nitration or synthesis grade.  The process is more efficient when fractionation precedes the refining treatment than when the acid-refining precedes fractionation. Suitable dispersion means are baffles, packing or plates.  The hydrocarbons and acid are preferably introduced in countercurrent flow.  Suitable pulsations have a frequency of 1 to 4 cycles/sec. and an amplitude of 4 to 20 mms. Suitable contact times are 5 to 20 minutes at 25 DEG  to 50 DEG C. for the conversion of materials containing not more than 2% by weight of non-aromatic unsaturates and not more than 0,5% thiophene sulphur to products containing less than 0,1% sulphur.  In Fig. 1 crude hydrocarbon from line 1 passes through preheater D to the bottom of packed column B and rises therein in countercurrent to 98% sulphuric acid from line 5.  Pulses of frequency 1,7 cycles/sec. and 14 mm. amplitude (in the column) are applied by piston 3.  Refined hydrocarbon and acid sludge are removed by line 4 from separation zone A and by line 2 from separation zone C respectively.

Title: Explosive-actuated fastener driving tools
IPC: B25C1/18
Filed: 1961-03-30
Abstract: 977,616. Cartridge-actuated tools. OLIN MATHIESON CHEMICAL CORPORATION. March 30, 1961 [April 12, 1960], No. 11733/61. Heading B4C. [Also in Division F3] An explosive-actuated tool for driving a fastener comprises a barrel 22 having a bore 27 along which a piston portion 2 carrying the fastener 1 travels, the tool being provided with a pair of jaws 203, 204 which, when the tool is thrust, during operation, against a workpiece, form an abutment means for the piston 2 so as to prevent the fastener from travelling more than a predetermined distance, the jaws being moved by a spring 201 into a position in which free passage of at least the fastener is permitted when the tool is in an inoperative position. The barrel 22 is mounted within a housing tube 54 connected to a collar 51, the latter being formed with lugs 51b providing a bayonet joint with the handle 20. A sleeve 202, mounted on the front end of the barrel, is adapted to hold the jaws 203, 204, the sleeve being urged by the spring 201 into a position in which the jaws are held together as shown in Fig. 1; the front ends of the jaws are formed with a taper 90 for co-operation with a corresponding taper 91 on a sleeve 200 slidable in a tube 70. A shield 24 is mounted on the front end of the tube 70, the rear end of the latter being adapted to abut a ring 82 slidably mounted on the barrel. A spring 26 acts between a flange 82a on the ring and a number of locking segments 80 urged inwardly by a spring 85. In normal operation, when the shield is pressed against a workpiece 100, as shown in Fig. 2, the tube 70 forces the ring forwardly so that an extension 82b thereon engages in projections 80, 81 on the segments, thereby allowing the barrel to move in order to cock the trigger mechanism. If, for any reason, the shield, together with the tube 70, were not fitted to the tool and the sleeve 200 pressed against the workpiece, the barrel would be prevented from moving to the cocked position since the segments would engage in a groove 22e formed in the barrel. The piston 2 is provided with a tapered abutment surface 5 so that, at the end of the stroke, the surface strikes a corresponding surface formed on the jaws, thereby halting the movement of the piston. The firing mechanism comprises a striking pin 34 in which is mounted a spring-loaded sear 42. When the tool is in the position shown in Fig. 2, a pin 40 on the breech-block 37 secured to the barrel, acts against the sear so as to depress the striking pin against the action of a spring 35. When the trigger 46 is then actuated the sear is depressed so as to release the striking pin. In a modification, the sleeve 200, jaws 203, 204 and sleeve 202 are held together as a unit by a synthetic plastic tube; alternatively, the spring 201 may be screwed on to the sleeve 202 and a releasable connection provided between the latter sleeve and the barrel 22. Specifications 756,942, 757,005 and 952,311 are referred to.
