Title: Improvements in or relating to magnetic slip devices
IPC: F16D37/02
Filed: 1951-07-03
Abstract: 687,549. Delivery flyer arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. July 3, 1951 [July 12, 1950], No. 15764/51. Class 120(ii) [Also in Groups XIX, XXIV and XXXIV] In a slipping brake device for use in handling relatively fine wire, a wire 4 is unreeled from a spool 2 by pulling it through the eye of a flexible flyer 6 connected to a member 9 fixed to an armature 26 rotatable in bearings 23. The armature 26 lies within a stationary permanent ring magnet 14 supported between pole pieces 15, 16 and a ring 19 of non-magnetic material, the whole being surrounded by an internally threaded magnetic sleeve 21 which can be screwed up and down on the pole piece 16. The armature 26 and magnet 14 are separated by a narrow annular gap 27, filled with a magnetically susceptible mixture such as finely-divided iron suspended in oil. The flux from the magnet 14, follows two alternative paths, one, 31, through the armature 26 and the magnetically susceptible mixture, which is thereby caused to solidify and couple armature 26 to magnet 14, and the second, 32, through a shunt path formed by the magnetic sleeve 21. By screwing the magnetic sleeve up and down on the pole piece 16, the reluctance of the circuit 32 can be varied and the flux passing through circuit 31 and the magnetically susceptible mixture thereby altered to adjust the coupling effect between the relatively rotatable parts. In operation, the tension resulting from unreeling the wire 4 causes the flyer 6 to revolve around the spool 2 against the coupling force tending to prevent the armature 26 from rotating within magnet 14, this force being constant regardless of the speed of rotation of the armature; accordingly the tension of wire 4 is constant. Reference has been directed by the Comptroller to Specification 649,553, [Group XXIV].

Abstract: 794,916. Reciprocating pumps. GASKELL & CHAMBERS, Ltd., [trading as NON-DRIP MEASURE CO.]. May 9, 1956 [June 2, 1955 ; July 5, 1955], Nos. 15815/55 and 19416/55. Class 102(1). An apparatus for dispensing measured quantities of liquid such as upper cylinder lubricant comprises a piston 6 working in cylinder 1, the piston rod 7 being formed with a duct 20. On pressing the piston rod by hand, liquid is discharged through passage 15 past non-return valve 19, of nozzle 18 the duct 20 allowing atmospheric air to enter the cylinder 1 above the piston 6. The piston is returned under the action of spring 10 and liquid is drawn from the container through pipe 13, past non-return valve 14 into the cylinder. The duct 20 allows the air above the piston to escape until the duct is closed by the end cap 8 when the small amount of air trapped above the piston 6 acts as a cushion whereby the piston is arrested smoothly and progressively. Alternatively, the duct 20 may be formed as an axial passage in rod 7 communicating at its upper and lower ends with transverse passages to operate as above. The member 2 is adapted to fit directly to the liquid container. The end delivery nozzle 18 is inserted in a socket 21, when not in use, which communicates with the interior of the container to allow for the priming of the pump. The cylinder 1 may be made of a transparent material. The pump unit may be mounted horizontally across the liquid container outlet and constitute a carry handle for the apparatus, in this case the delivery nozzle is mounted directly on the end of the pump cylinder. A stand or base may be provided for holding the liquid container. Specification 718,303 is referred to.

Title: Improvements in forming compounds from acetylene
IPC: C07C209/60
Filed: 1931-05-30
Abstract: The reaction of acetylene with other organic compounds, such as phenols, alcohols, amines, ethers, or esters, is effected under substantially anhydrous conditions in the presence of a catalyst comprising a mercuric compound and a fluoacid, or a mercuric salt of a fluoacid.  Suitable acids are fluoboric and fluosilicic acids, and these may be used in the form of the mixture of free acid and alkyl borate or silicate obtained by passing boron fluoride or silicon fluoride into methyl or ethyl alcohol.  In the examples, (1) dry acetylene is passed at a temperature up to 100 DEG  C. into a dry mixture of glycerol, mercuric oxide, and a solution of boron fluoride in methyl alcohol; glycerol acetal and dimethyl acetal are obtained; (2) ethylene glycol ethyl ether is treated with dry acetylene at a temperature up to 100 DEG  C. in the presence of mercuric oxide and a solution of silicon fluoride in ethyl alcohol; the acetal of the glycol ether is obtained; (3) ethyl lactate is treated with acetylene as in example (1), giving a product of uncertain constitution; (4) aniline is treated as in example (1), yielding ethylidene aniline; (5) phenol is treated as in example (1), yielding, probably, vinylphenols.  The process may be effected in a solvent, e.g. chlorobenzene, benzene, or toluene, although the hydrocarbons mentioned may react to some extent with the acetylene to form ethylidene derivatives.  The application of the process to the manufacture of acetals of the alkyl ethers of diethylene glycol is excluded.  Specification 318,980, [Class 2 (iii), Dyes &c.], is referred to.

Title: Improvements in valve gear for fluid pressure percussion tools
IPC: B25D9/20
Filed: 1930-05-27
Abstract: 355,378. Valve-gear for percussive tools. KNIBBS, R. A., 29, Wood End Park Crescent, Haves, Middlesex, and WAKEFORD, L. S., 126, Abercromby Avenue, High Wycombe, Buckinghamshire. May 27, 1930, No. 16366. [Class 122 (ii).] A percussive tool is provided with a pair of concentric sleeve valves 1, 2 arranged in a chamber 12 surrounding the upper end of the cylinder and in engagement with corresponding diameters thereof. The valves have parts with differential areas 1b, 2b, 1c, 2c respectively. The parts 1d, 2d, opposed to the actuating - areas 1b, 2b are put to atmosphere by vents 18. The valves are opened in succession, and closed simultaneously to permit expansion. The valve ends 1c, 2c engages seats 13, 14 respectively to control the admission, and their lower adjacent ends control exhaust ports 9, 9a respectively. The actuating areas 1b, 2b are formed upon external collars 1a, 2a respectively, which collars may be arranged in the same or in separate chambers. The collars during the supply of pressure fluid to either end of the cylinder abut, and when the piston passes one or the other of two ports 5, 6, fluid pressure passes from the cylinder to the opposed collars and cuts off the fluid-supply. The compression in the cylinder ends together with the pressure of the fluid supply on the valve seats effects the reversal of the valves. When the piston in rising uncovers port 6, pressure fluid passes to the chamber 3, closes valve 2, and opens the exhaust from the forward cylinder end through passage 11, 19, and ports 9a. Fluid beneath the piston expands until the exhaust ports 9 are uncovered. When the piston passes relief ports 2, 3 in valve 1 in communication with the atmosphere through auxiliary ducts 18, the compression acts on the upper end of the valve 1 to reverse it. Some of the cushioned air may pass by vents 23 and vents 18 to the area 1d and help throw the valve 1. Ducts 25 communicating with the space between the areas 1b, 2b release some of the cushioned air and accelerate the closing of the valves. The valve action can be regulated by a screw 27 in the passage leading to the chamber containing the valve collars.

Title: Hydrostatic extrusion method
IPC: B21C23/00
Filed: 1974-04-11
Abstract: 1466575 Extruding KOBE STEEL Ltd 11 April 1974 [11 April 1973 29 May 1973 4 June 1973 24 Aug 1973] 16410/74 Heading B3P In a method of hydrostatically extruding a tubular billet 14 using a mandrel 17 the mandrel is advanced into the billet to effect a seal between the nose 15 of the billet and the die and mandrel before extrusion. The mandrel 17 has a mandrel ring 16 which abuts a supporting sleeve 22 to position the mandrel tip 19 in the die 13. The initial advance of the mandrel enlarges the frusto-conical nose of the billet to effect the sealing. The mandrel may have an elliptical cross-section tip (37), Fig. 4A, to produce tubes having a non-circular bore. Alternatively the mandrel may be provided with a pair of parallel core tips, 47, Fig. 5, forward of a frusto-conical sealing surface 45. When extruding tubes in which the bore is asymmetric or non-circular the mandrel may be prevented from rotating relative to the die. This is achieved by using a position aligning member 57, Fig. 8, provided with a rear recess in which a key 60 is provided to engage a slot on the mandrel end 56a. Grub screws 59 are used to retain the member 57 at the desired angular and axial position on the rear end 65 of the mandrel supporting sleeve 58. The mandrel 56 is supported in bores 61, 62 which may be of square cross-section if the key 60 is not provided. The relative angular positioning of the die and mandrel may alternatively be produced by rotation of the die. The mandrel may be formed in two parts 96, 97, Fig. 14, which are brazed together by a softer material than the parts which need not be of the same material. A ring (105), Fig. 16, may be provided over the brazed joint. In a final arrangement to produce smooth inside wall tubes the mandrel has a shaped tip 110, 111, Fig. 17A, so that a void is provided between the billet and part of the tip during extrusion. The void may have vent passages (119), (120), Fig. 18 (not shown).

Abstract: 1,184,165. Reactive dyes. FARBENFABRIKEN BAYER A.G. 5 April, 1968 [7 April, 1967], No. 16484/68. Heading C4P. The invention comprises reactive dyes containing at least one pyridazine containing at least one eliminatable fluorine substituent. (Eliminatable means the fluorine substituent will react with OH or amide groups of fibre material and will split off to form a covalent bond between dyestuff and fibre.) The preferred dyes have the general formula wherein D is a dye radical, e.g. of the mono-, di- or poly-azo which may be metallized, anthraquinone, phthalocyanine, stilbene or nitro series, R is H, C 1 -C 5  alkyl or hydroxyalkyl and R 1  is H or a substituent atom or group, D preferably containing at least one sulphonic acid group. They are prepared by introducing by known methods, e.g. condensation of an amine with a tetrahalopyridazine at least one fluoropyridazine radical into a dyestuff or dyestuff intermediate and when an intermediate is used, converting this, e.g. by diazotization and coupling, acylation or sulphonation, into the final dyestuff. Many dyes are prepared which give all shades on wool, silk, synthetic polyamides and polyurethanes and natural and regenerated cellulose.

Abstract: 628,421. Pencil holders. WHITE, P. S. June 23, 1947, No. 16520. [Class 146 (iii)] [Also in Group XX]  A pair of compasses is provided with an adjustable lead pencil and a lead-sharpening device. The pencil leg 17 has a lead holder 19 comprising a barrel 21 internally threaded to receive a lead adjusting screw 22 which exerts pressure on the lead 18 through a spring 23. The pressure is adjusted by means of a finger piece 34 which forms a conical friction clutch with a part 36 attached to the head of the screw 22 and which is urged into engagement by a spring 38 encircling the reduced diameter shank 35. On adjusting the length of the screw the clutch 34, 36 will slip when a predetermined spring pressure is reached. The sharpening device comprises a flat file 24 held in a dove-tailed groove 25 so that it may be reciprocated along the inside of the leg 17. The channel 25 is held by a yoke 26 screwed to the leg and bears at its upper end a pair of finger pieces 29. The upward movement of the channel 25 is limited by a stop 31 and the downward movement by the engagement of the part 32 connecting its finger pieces against the upper edge of the yoke 26. The lead abuts against the lower end of the file 24 which is plain to form a stop for the lead. In a modification the channel 25 is dispensed with, the finger pieces 29 being attached to the file 24 which reciprocates in a dovetailed slot provided on the inside of the leg 17.
