Title: Improvements in fluid actuated rotary tools
IPC: B23B45/04
Filed: 1924-05-05
Abstract: 232,046. Marks, E. C. R., (Ingersoll-Rand Co.). May 5, 1924. Drilling-machines.-In a fluid-actuated rotary tool for drilling, reaming, tapping, flue rolling, stud setting, bolt tightening, running-down screw spikes, setting valves, &c., comprising a casing A, a crank cover B. and a crank shaft H actuated by a fluid-operated reciprocating motor within the casing, one or more passages communicating with the interior of the casing A and with the atmosphere are provided in the crank shaft H and crank pins W, whereby, while the crank casing is vented, the centrifugal force occasioned by the rotation of the crank shaft separates the lubricant suspended in the air current passing through the passages and forces this lubricant through radial holes c to the crank pin bearing surfaces. The hollow bores of the crank pins W, which are fixed in a slotted centre web V by pins X and a bolt h, communicate at one end with the crank chamber and at the other end with hollow shaft ends a, Y by passages j in the end webs, the end a being open directly to the atmosphere and the end Y being in communication with the atmosphere through a. vent q in a cap p. In a modification the shaft end Y is not hollow, and a single continuous passage, which is open to the crank case at the web k adjacent the end Y, extends through the crank pins and end a, to the atmosphere. The tool spindle E, carrying the tool in a socket D. is driven from the crank shaft through gearing R. S. A rotary valve Q, controlling the distribution to the cylinders of the motive fluid, which enters through one of the handles F of the machine, is driven by al gear U meshing with a gear T integral with the gear S. The feed screw z works in a sleeve v mounted in the casing, and an extension 6 of the sleeve carries the inner race of a ball or roller bearing 5, the outer race of which is mounted in the gear T. This bearing transmits the thrust of the tool spindle E to the feed screw centre 3. The tool is ejected from the socket D by a pin 7 when the feed screw is screwed down.

Filed: 1940-07-02
Abstract: 542,326. Artificial filaments. TAYLOR, W. I., and POOL, W. July 2, 1940, No. 11150. [Class 2 (ii)] In the dry-spinning of artificial filaments. the spinning jet is first filled with a liquid compatible with the spinning solution and is then applied, while still full, to the source of supply of the spinning solution. Spinning then proceeds, optionally with the preliminary application of vibrating pressure to the surface of the spinning jet, to assist in freeing the orifices. As shown, the spinning jet fitting 4, Fig. 2, has a flanged metal disc 6 with orifices 7 having a layer of filter material 9 and a perforated plate 10. The upper part of the jet fitting contains a ball 13, which is operated by a spring 14 to fit the conical seat 12 and to close the opening therein when free to do so. The jet fitting is attached to a member 61 which is screwed on to the supply pipe 17 for the spinning solution and has a ball valve 19 operated by gravity. The nut 15 is unscrewed to release the jet fitting from the supply pipe, and the fitting is connected to the header 25, Fig. 4, through a pump 24 so that spinning solution or some other compatible liquid is forced through it for a period. It is then removed, the liquid being retained by the ball valve 13, and connected again to the supply pipe 17, which has been kept closed by the valve 19, and both valves are opened by the apertured washer 22, which presses both balls 13, 19 from their seats. Normal spinning then proceeds. A small pneumatic tool 26, Fig. 5, can be connected by a flexible hose 27 to an air supply. The tool has a wooden peg 29 which can be applied to the face of the jet to cause rapid vibration and so clear the orifices of obstructions.

Title: Improvements in or relating to the heat treatment and concentration of copper ores
IPC: C22B15/00
Filed: 1925-05-02
Abstract: 255,961. Moulden, J. C., Taplin, B., and Metals Production, Ltd. May 2, 1925. Flotation processes.-In the heat treatment and concentration of copper ores described in Specification 250,991, [Class 82 (i), Metals, Extracting &c.], in which the ore is heated with solid carbonaceous matter in the presence of halogen, the copper obtained is separated from the treated material by froth-flotation. Particles of a size such as to interfere with the flotation are eliminated by screening or water-classification, or the material may be ground to reduce the coarse particles to the required fineness. The size of the particles to be removed may be determined by experiment, but, in general, particles greater than one fortieth of an inch in diameter should be removed. When the heat treatment is carried out with agitation, as for example in a rotating retort., the copper tends to collect into aggregates, which may be wholly or partially disintegrated by grinding or agitation, when the coarse barren material may be removed by screening and the remaining fines subjected to flotation. Alternatively the material may be screened so that the copper aggregates are retained in the screen while still whole and may then be disintegrated and concentrated by flotation.

[Class 1 (i)] [Also in Group IV] In the vapour phase conversion of carbonaceous materials in the presence of a ferrous metal and a catalyst susceptible to contamination by iron, which catalyst is periodically regenerated by oxidation, there is maintained in the feed to the conversion zone from 0.0006 to 0.015 per cent. of sulphur in the form of elemental sulphur or a reducible sulphur compound, thereby inhibiting the contamination of the catalyst by iron. Reducible selenium and tellurium compounds may be similarly used. Preferred compounds are carbonyl sulphide, sulphur trioxide, thiophenic compounds, mercaptans, dialkyl sulphides and organic polysulphides. The process is applicable to the dehydrogenation of hydrocarbons, particularly of propane and butane, at temperatures above 500‹F. using supported chromium oxide catalyst in a chrome steel converter.
Patent GB-775766-A (GB)
Title: Process for dyeing and printing fibres of polyacrylonitriles
IPC: D06P3/72
Filed: 1954-04-22
Abstract: Polyacrylonitrile fibres are dyed or printed with a triphenyl-methane dyestuff which is free from sulphonic acid groups and which contains a secondary phenylamino group in at least one of the three phenyl nuclei in para-position to the central carbon atom, the dyestuff molecule containing as substituted amino groups only secondary phenylamino groups.  The three phenyl nuclei or the external phenyl residues may contain other substituents such as alkyl, alkoxy or other amino groups or halogen atoms.  The dyestuffs are applied as their salts with, for example, hydrochloric, sulphuric, phosphoric, amino - sulphonic, acetic, propionic, chloracetic, benzoic or salicylic acid.  When the triphenyl - methane contains an acid salt-forming substituent such as carboxylic acid or sulphonic acid amide group, they may be employed in the form of their so-called inner salts.  If desired the dyestuffs may be applied in the form of their carbinols and converted into salts on the fibre by the action of acids previously or subsequently applied.  Sparingly soluble dyestuffs may be applied by the dispersion dyeing technique.  Dyeing is preferably effected in a weakly acid bath at a raised temperature and, if desired, under pressure, and the dyeings may be subsequently steamed or subjected to a heat treatment.  Numerous examples are given.

Abstract: 1501262 Control of D.C. motors ROSEFAIR ELECTRONICS Ltd 22 March 1976 [20 March 1975 17 Oct 1975] 11739/75 and 42758/75 Heading H2J To maintain the continuity of contact between a contactor on a model vehicle driven by an A.C. or D.C. motor and a fixed conductor supplied with power to energize the motor, the conductor is supplied with an oscillating signal whose amplitude and frequency are such that the voltage breaks down a dielectric layer on the conductor, formed, for example, by dust, grease or metal oxide. Embodiments of the invention relate to a model railway whose track is supplied with direct current to drive the D.C. motor of the locomotive. In Fig. 3 the output of a transformer/rectifier unit 20, 21 is applied to the railway track at C through a transistor TR1 and also to oscillator 22 and members C1-C3, D1 forming a multivibrator, whose mark/space ratio is varied by adjustment of a resistor RV to produce corresponding control of the transistor TR1 and so vary the locomotive speed in a direction determined by a reversing switch S1. The track is also connected to the output of a high frequency oscillator 23 consisting of members T2, TR2, R2, C5 and 24, the oscillator output being damped by the relatively low impedance presented to its output when there is a good electrical connection between the locomotive and the track. This condition also produces charging of a capacitor C7. When the locomotive encounters dielectric on the track presenting a high impedance to the oscillator, the capacitor C7 discharges to cause the oscillator to produce an output to break down the dielectric, the consequent current flow through resistor R3 and reduction in voltage applied to the oscillator causing its output amplitude to decrease, until it is again damped and the capacitor C7 is recharged. A shorting switch S2 and neon tube L shunt the oscillator output, the tube L indicating the presence of dielectric on the track. In other embodiments the oscillator output is always present, one embodiment consisting of a rectified supply (1, 2) fed to the track through an adjustable resistor (7) in parallel with a capacitor (8) feeding the oscillator output to the track, Fig. 1 (not shown), and another embodiment consisting of a multivibrator (12) controlling, through an adjustable resistor (14), the mark/space ratio of a transistor (13) switching a rectified D.C. supply (11) to the primary winding of a transformer having two secondary windings, one (16) being connected directly to the track and the other through a rectifier bridge (15), Fig. 2 (not shown). Suitable ranges are specified for the amplitude and frequency of the oscillator output.
