Title: Improvements relating to the separation of intermixed metals
IPC: C22B7/00
Filed: 1937-11-24
Abstract: 506,284. Separating mixed metal borings by crushing and sifting. EVANS, A. J., and WADDLE PATENT FAN & ENGINEERING CO., Ltd. Nov. 24, 1937, No. 32424. [Class 59] A method of separating mixed metals in borings or turnings comprises heating the mixed metal borings in an oil bath to a temperature below the melting point of either or any of the borings, but at which one Of the metals becomes brittle and then subjecting all the borings to a crushing or breaking action so that the more brittle borings are broken into small pieces, and thereafter separating the smaller pieces from the other larger metal borings by a sieving action. White metal borings may be separated from borings of gun metal, brass, copper, &c. by heating in a bath of mineral oil to a temperature of say 200‹ C. or to a temperature below that at which the white metal would become pasty or at which the white metal would turn into a powdered form. The borings may be classified into different sizes and each class fed through a hopper 4, Fig. 1, to a rotating, perforated, sheet-metal sieve 1 containing rollers 2 and mounted in bearings 9 carried by a cover 10 of a container 3 forming an oil bath heated by burners. The rollers 2 are maintained in the inclined sieve 1 by partitions 11 and a bar or bars may lie or bear on the top of the sieve to clear the apertures therein. The crushed white metal borings fall through the sieve into the bottom of the oil container and are removed by a screw conveyer 7, the other metal borings passing out through the end of the sieve into a part of the container bounded by a partition 5. The white metal from the container 3 may be further sifted on a perforated plate in order to remove any brass &c. borings which fall through the sieve 1 with the white metal. The sieve may be rotated by a handle 8 or may be power driven and elevators may be provided to remove the separated borings. Oscillating or combined rotary and oscillating sieves may be used instead of a rotary sieve and means other than balls or rollers may be used for breaking up the white metal. Several sieves in one tank lying parallel to one another may be used.

Abstract: 447,273. Automatic control of a body in motion. RADIO NAVIGATIONAL INSTRUMENT CORPORATION, 270, Madison Avenue, New York, U.S.A. Nov. 12, 1934, No. 32555. Convention date, Nov. 10, 1933. [Class 38 (iv)] [See also Groups XL and XXXVIII] Waves radiated from a single source or beacon station are received on at least two separate and similar directional aerials or pick-up devices, set at a fixed angle to each other on a craft to be navigated, and the received signals are separately amplified and measured by two instruments, which determine their ratio and thereby indicate the direction of the source. The craft may be automatically steered on a predetermined course, in dependence on the movement of the point of intersection of the two needles along the median line of a calibrated dial. The invention is applicable to sound and light, as well as to wireless waves. The pick-up from two frame-aerials 51, 52, Fig. 19, set at an angle to each other, is applied after amplification and detection to two voltmeters 17, 18, the indicating-needles of which show the direction of the beacon station by their point of intersection on a dial of the kind shown in Fig. 7. The output from the amplifiers may be fed to, or paralleled with a differential relay 123, Figs. 14 and 15, which in turn energizes other relays 127, 133 to control the rudder 134 of the craft, and so keep it automatically on a set course. The segments 125, 131 are geared to rotate with the rudder, say to the right as shown in Fig. 15, or to the left, until the armature is disconnected, whereupon the rudder swings back to its original position. This operation is repeated until the craft is again heading on its correct course.

Title: New guanidine compounds, process for their preparation and their use as analytical reagents
Filed: 1954-11-11
Abstract: The invention comprises salts of guanidinophenyl alkyl ethers of formula <FORM:0773410/IV(b)/1> where R is an alkyl radical having more than 4 carbon atoms and A- is a radical of an acid such as carbonic, nitric, sulphuric or tartaric acids or hydrohalogenic acids and excepting chromic, permanganic, perchloric and peroxy acids.  The compounds are prepared by reacting a salt of a p-aminophenol alkyl ether with cyanamide preferably in a solvent or solvent mixture having a boiling point between 50 DEG  and 150 DEG  C.  The cations of the compounds form picrates of very low solubility, and the compounds are therefore used for the estimation of picric acid or picrates and also to convert picrates of organic bases into the free base or another salt by metathesis.  In examples: (1) the concentration of picric acid in aqueous solutions thereof is determined by the addition of a solution of the compound wherein R=octyl and A-=Cl-, the insoluble picrate being precipitated and weighed; (2) the picrate contents of murexine dipicrate (i.e. b -4(5)-imidazylacryl-choline dipicrate), hercynine dipicrate, choline picrate and glycine picrate are determined by the procedure of (1); (3) hercynine is obtained from hercynine dipicrate by reaction with a compound wherein R= dodecyl and A-= 1/2 CO3- -, tyramine hydrochloride is obtained by the reaction of tyramine picrate and a compound wherein R=dodecyl and A-=Cl-, murexine chloride hydrochloride is obtained by the reaction of murexine dipicrate with a compound wherein R=octyl and A-=Clin hydrochloric acid solution and glycine is obtained from glycine picrate by reaction with a compound wherein R=octyl and A-= 1/2 CO3- -; (4) (a) p-guanidinophenyl isoamyl ether carbonate is prepared by reacting p-aminophenyl isoamyl ether hydrochloride with cyanamide and treating the resultant hydrochloride in solution with sodium bicarbonate, (b) p-guanidinophenyl isoamyl ether sulphate is prepared by treating the carbonate with sulphuric acid, (c) p-guanidinophenyl octyl ether carbonate is prepared as in (a) and the corresponding hydrochloride and nitrate are also prepared, (d) p-guanidinophenyl dodecyl ether hydrochloride is prepared as in (a) and the corresponding carbonate and tartrate are also prepared, (e) p-guanidinophenyl hexadecyl ether hydrochloride is prepared as in (a).  p-Aminophenyl octyl ether hydrochloride is prepared by the reduction of p-nitrophenyl octyl ether with hydrogen in the presence of Raney nickel, followed by the addition of hydrochloric acid.  p-Nitrophenyl hexadecyl ether is prepared by reacting potassium p-nitrophenate with cetyl bromide.

Abstract: 294,824. Armstrong, J. J. V., (Union Special Machine Co.). Dec. 5, 1927. Seams; work guides; presser-feet. - In a machine for sewing overlapping fabric sections and joining them by covering stitches, a guiding channel between fixed and re. silient sections of the presser-foot receive the edges of the fabric in such a way that one edge is vertical and the other inclined, and extensions of the parts of the presser-foot cause the edges to overlap ready for stitching after trimming. The stitching is effected by three needles, the middle one only of which penetrates both edges. A surface thread c is carried across the seam laid by a thread-carrying member and a hook co-operating with the needles beneath the work support is a single looper of the thread carrying type. The presser-foot 23 has a main section 24 and an auxiliary section 26, yieldingly held down by a spring 27. The sections a.re spaced apart to form the guide channel 28 for the edges of the material, one part of which has a vertical edge and passes under the section 24, Fig. 7, and the other an inclined edge and passes under the section 26, A fixed trimming blade 29 is mounted on the section 24 and a movable blade 32 on the resilient section 26. As the work is fed to the needles the edges are trimmed and extensions 34, 35 on the presser foot sections trim the. edge f under the edge f<1>. The resilient part 26 enables the machine to take materials of varying thicknesses. The projecting part 35 of the resilient presser-foot section carries two stitch fingers 36, 37.
