Title: Improvements relating to centrifugal hydro extractors
IPC: D06F49/00
Filed: 1943-05-06
Abstract: 563,801. Switches. JONES, F. S. May 6, 1943, No. 7174. [Class 38 (v)] [Also in Group II] In a machine for centrifugally extracting water from wasted articles, electrical means are used (a) to prevent the hinged lid from being raised until the cage-driving has been shut off, and until the speed is very low, (b) to prevent the machine from being started before the lid is closed. The cage within the body 10 of the machine is geared to a horizontal shaft 11 carrying fast and loose pulleys. A starting handle 13, for moving the belt from one to other of the pulleys, obstructs the raising of the lid 14 when the machine is being driven. A centrifugal switch, associated with part of the driving gear, controls the current to a locking device 31 mounted on top of the body 10. In one form, Fig. 3, slip rings 17, 18 insulated from one another, are placed within the driving pulley 12 and are supported by terminal posts 20, 21 mounted on a fixed plate 22. A switch arm 23 is pivotally mounted in the pulley and, under centrifugal action, bridges the slip rings to complete the circuit through the locking device. When the pulley is stationary, an adjustable spring holds the arm 23 clear of the slip rings. The arm may be weighted, the weight being adjustable. The looking device 31 contains a solenoidoperated pin or latch which moves into an opening in a bracket 34, secured. to the lid 10, when the .solenoid is energized. A cover may enclose the bracket 34, to prevent interference with the pin. When the machine is driven electrically, the fastening means for the lid comprises a latch 61, Fig. 7, on a bar 57 which on being moved to secure the lid by sliding the latch under a hook 63, closes a switch 64 in the contactor circuit permitting power to be switched on. A driving motor 37 is controlled. by a centrifugal switch mounted at the upper end of the motor shaft 38. The switch has a stem 39, mounted in an insulated bush 40 and supports a swinging lever 42 at the end of an arm 41. A brush 43, under centrifugal action, engages a metal ring 46 mounted on an insulating disc 48. Alternatively, a metal disc may be provided with insulating bushes through which pass the securing screws. The electrical circuit is completed through a spring finger 51. The locking device comprises a solenoid 53, connected in series with the centrifugal switch, which actuates a pin 54 to enter a hole in a block 56 carried by the slidable bar 57 extending across the top of the lid 14. The rod is supported in bearings 58, 59, and is hinged at 60. The rod actuates a switch 64 of the push type connected in circuit with the contactor secondary circuit. The motor 37 cannot be started until the switch 64 is closed.

Title: Method for the production of iron-silicon alloys
IPC: C21D8/12
Filed: 1959-03-03
Abstract: Transformer silicon iron alloys with 2-5% silicon, less than 0.01% nitrogen, oxygen, sulphur and phosphorus and less than 0.002% titanium and aluminium, are cold reduced at least twice and heated above 700 DEG  C. between each cold deformation, the last deformation step being between 50 and 80%, and heated above 1100 DEG  C. in a medium controlled in such a manner than silicon oxide is not formed and/or that silicon oxide which may be present on the surface is eliminated.  The first cold deformation step may be 10-20%, followed by annealing at 750-950 DEG  C. in an atmosphere of dry hydrogen with a dew point of - 30 DEG  C. at a vacuum of at least 10-2 Torr. Deformation effected from the second to the penultimate step may be 50-90%.  Before the last deformation heating may be at 850-1000 DEG C. and the final heating at 1200-1300 DEG  C. carried out in hydrogen with a dew point of - 70 DEG  C. and a vacuum of 10-5 Torr. Alternatively, the vacuum may be reduced while heating by allowing the diffusion of hydrogen at a dew point of - 30 DEG  C. until the original vacuum is not lower than 10-1 Torr, or the heating may be performed in an inner furnace zone purged with hydrogen at a dew point of - 70 DEG  C. and at a lower pressure than a surrounding zone purged with hydrogen at a dew point of - 30 DEG  C.  During heating the rolled strip may be protected by a screen of iron, iron alloy or iron-nickel alloy which acts as a getter.  The silicon iron alloy may solidify from its melt by unidirectional cooling to produce columnar crystals elongated in the direction of rolling.  Reference has been directed by the Comptroller to Specification 807,809.
Patent GB-492265-A (GB)
Title: Manufacture of thyroxin
Filed: 1937-03-13
Abstract: In manufacturing thyroin from iodinated proteins by a hydrolytic decomposition, the iodination is carried out in feebly alkaline aqueous solution at a moderately raised temperature by gradually adding iodine, insufficient in quantity for complete iodination of the protein, hydrolysing the iodinated protein with alkali, treating the hydrolysate with acid, e.g. hydrochloric, sulphuric or acetic acid to obtain an acid-insoluble product containing thyroin and purifying this product by recrystallization from sodium carbonate solution and by precipitation by acid from a solution in alkaline alcohol.  The product obtained by treating the hydrolysate with acid may be purified by dissolution in alkali and reprecipitation with acid prior to purification by recrystallization.  In examples: (1) purified serum globulin is heated in dilute sodium bicarbonate solution and finely pulverized iodine is added gradually with stirring.  The iodinated globulin is centrifuged, dissolved in water, dialysed, frozen and dried.  It is then boiled in barium hydroxide solution, and the hydrolyzate filtered hot, cooled, and filtered to remove barium hydroxide.  The filtrate is acidified and the precipitate (A) allowed to deposit.  The precipitate from the hot filtration of the hydrolysate is treated with acid, the insoluble residue separated by centrifuging, and extracted with hot alkaline sodium sulphate solution.  Precipitate (A) is then dissolved in this solution which is then filtered and acidified while boiling with dilute sulphuric acid.  The whole is then cooled and filtered and the filtrate washed with dilute acetic acid.  This product is then recrystallized from sodium carbonate solution, dissolved in alkaline alcohol and again precipitated by acid; (2) thyroin is similarly obtained from casein.

Title: Improvements in telegraphic transmitters
IPC: H04L27/12
Filed: 1941-06-13
Abstract: 549,979. Wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and WASSELL, H. J. June 13, 1941, No. 7522. [Class 40 (v)] In a radio or carrier-current telegraphic transmitter, the oscillation frequency is varied progressively by the succession of keying impulses. These impulses pass through a relay EM which attracts its armature PL and gives a reciprocating motion to two pawls PW1, PW11. The upper one engages a ratchet-wheel RW1 and by means of a worm WW rotates a vertical shaft SH11 carrying a pulley PU for driving a tuning-element of the transmitter and so varying the frequency. The pulley may be freed from its shaft by rotating a thumb screw to ease the clutch CL. In order to reverse the drive after a semi-rotation of the shaft SH11, a cam CM is provided with oppositely-directed humps HP11 at opposite ends of a diameter. These co-operate with pivoted levers LVI, LV11 and a bow spring to rock a lever AM and lift a rod BA which carries stops ST1, ST11 for lifting one pawl out of gear and allowing the other to be raised by a spring HS into operative relation with a second ratchet for driving in the opposite direction. Instead of reversing the drive, the cam may be arranged to indicate that resetting by hand should be effected, or it may itself initiate automatic resetting. The frequency-changing apparatus may be put out of action when desired.

Filed: 1976-02-25
Abstract: 1480997 Coffee aroma frost GENERAL FOODS CORP 25 Feb 1976 [26 Feb 1975] 07530/76 Heading A2B A coffee aroma frost is produced from a coffee aroma bearing carbon dioxide containing gas by entraining said gas with a steam of non-condensable gas and cooling the combined stream to condense out the CO, and coffee aromitics in the form of a frost, the remaining non-condensable gas being vented through a filter element which traps entrained particles of frost on its surface. The preferred method used a scraped wall heat exchanger as shown in Fig. 1. The gas stream enters at 16 and is condensed on wall 14 where the frost is scraped off by rotating scrapers 18, to fall into flask 22 for collection. The non- condensed gas exits at 19 through filter 21, which is periodically cleared of the frost which forms thereon. The feed gas stream is suitably that from a coffee grinder and the frost product may be mixed with a liquid glyceride and then padded to soluble coffee powder.

Title: Rotary end-mills
IPC: B23P15/34
Filed: 1937-03-15
Abstract: 483,944. Grinding milling - cutters. WOODLING, G. V. March 15, 1937, Nos. 7584 and 7585. Convention dates, March 14, 1936 and Sept. 21, 1936. [Class 60] [Also in Group XXII] An end-milling cutter has a number of spiral fillets 18 separated by flutes 17, the bottoms of which constitute outer surface portions of the body each fillet having a cutting- edge with a clearance surface extending therefrom and lying wholly outside the body of the tool. Each fillet has a narrow arcuate undercut side 25 extending from the flute and a wider side 26. The end of each fillet carries a short cutter edge 20 with a sloped clearance region 21. The area 22 between the cutting edges is of concave formation. A sloping recess 14 is cut in the body portions in the bottom of each flute and a clearance portion 23 extends from each part 21 to the recess 14 where it converges to the flute 17. In making the tool the central concave portion may be formed by rotating the work against a grinding-wheel 30, Fig. 4. The recesses 14 are then cut by means of a grinding-wheel 30, Fig. 6. The next step is to grind the cutting clearance on each fillet by means of a cup-shaped grinding- wheel 32, Fig. 9, the axis of the work being slightly inclined to that of the wheel to obtain the required relief. The final step is to grind the clearance surfaces 23 by a cup-shaped grinding-wheel, Fig. 11, the work axis being tilted both in the plane of the paper, as shown, and also at right-angles to this plane. In a modification, Fig. 14, the cutter has a centring hole 27 and a concave portion 22 and the cutting edges 20 lying outside the body portion have a clearance surface 21 and a clearance portion 23 extending to a point 29 on the edge of the concave portion. The line 30 is perpendicular to a tangent to the spiral of the undercut side 25 and cuttings tend to be forced along this line onto the side 26 and then along the flute away from the cutting end. In another modification, the central depressed part of the cutting end may be of conical form or in some cases a short axial wall, Fig. 19, may separate the depressed portion from the outer cutting portion of the tool. In making these forms, a blank may first be formed with a concave central portion by means of a rotary profiling tool. The spiral fillets and flutes are then formed and the cutting edges with their clearances 21 formed with a cup-grinder 32, Fig. 2. The clearances 23 are then ground on the ends of the fillets in a similar manner to that shown in Fig. 11. In some cases the clearance 23 may be a continuation of the clearance 21 and a separate grinding operation to form the clearance 23 is not required. The concave part may be polished to remove burrs by a wheel 41, Fig. 26, rotating on an axis parallel to the cutter.
