Title: Improved process for immunising yarns of vegetable origin to direct dyeing dyestuffs
IPC: D06P1/651
Filed: 1929-09-23
Abstract: 319,584. Soc. of Chemical Industry in Basle. Sept. 21, 1928, [Convention date]. Yarns, treating with liquids, gases, and vapours.-Textile materials of vegetable origin, such as cotton,' linen or regenerated cellulose artificial silks, are immunized to direct dyestuffs in a single operation, without weakening the fibres, by treating the material without any preliminary treatment with alkalies or acids, with an anhydride or chloride of an aromatic carboxylic acid, such as phthalic anhydride, benzoyl chloride or phthalyl chloride, in the presence of a tertiary base, such as pyridine, quinoline, triethylamine or diethylaniline. In an example, cotton is treated with phthalic anhydride and pyridine; the product is immune to direct and acid dyes, but has a strong affinity for basic dyes. Specification 284,358 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to a similar use of the anhydrides and chlorides of the aliphatic dicarboxylic acids, such as maleic and succinic anhydrides. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in locking washers for use with nuts or other screw threaded members
IPC: F16B39/24
Filed: 1938-10-04
Abstract: 519,459. Locking nuts. GUEST, KEEN & NETTLEFOLDS, Ltd., and CHAPPUIS, J. A. Oct. 4, 1938, No. 28826. [Class 89 (i)] A hard metal locking washer 10 has ratchetshaped teeth over part or whole of both faces. There are relatively few teeth 13 on one side to enable the teeth to indent the adjacent surface when the nut 16 is being screwed up. The inclined sides 12 of teeth 11 are inclined in the same direction as the screw thread but more steeply to provide a wedging action when the nut is unscrewing. On the reverse face, the sides 14 of teeth 13 are inclined opposite to the thread. The washer is reversible and may be gapped radially or otherwise. The end may be displaced from the plane of the washer to provide a spring lock. Specification 514,923, is referred to.

Abstract: 305,085. Beatty, W. E., (Bell Telephone Laboratories, Inþ.). Oct. 29, 1927. Extrusion niachines.-Means for impregnating tyre cords, fabrics, braids or servings on wires, or electric conductors with insulating and protective compounds, comprises a chamber containing viscous or pressure-equalizing fluid at atmospheric pressure, and a tubular channel formed with a small orifice leading to an extrusion chamber where a gutta-percha covering is applied under high pressure. In the embodiment, an electric conductor 10 passes through an open reservoir 12 and a long friction tube 13 to an extrusion chamber 14 where a. layer of plastic material is applied over the flux layer at high, pressure. The insulated conductor is passed through a cooling bath to set the insulation, and is wound on a take-up reel. The reservoir 12 contains semi-fluid viscous material 20, and the chamber 14 is filled with heavy plastic insulation 21 such as gutta-percha or rubber. The channel 13 is designed so as to develop pressure at the orifice 22, to overcome the back pressure in the extrusion chamber. Resistance heaters 26, 27, 28 regulate the temperature and viscosity in the tube 13, reservoir 12, and extrusion chamber 14, respectively. Specification 242,814 is referred to.

IPC: C07C51/363
Filed: 1957-09-13
Abstract: The invention comprises a :a -dichloroisovaleric acid and its salts. The acid may be prepared by treating a -chloroisovaleric acid at elevated temperatures with chlorine in the presence of a phosphorus-containing catalyst.  The reaction takes place in the range 150-185 DEG  C. and good results are obtained using at least one mol. of chlorine per mol. of chloroisovaleric acid and about 3-7 per cent by weight of catalyst.  Phosphorus trioxide, trichloride and pentachloride and phosphoric acid are found to be suitable catalysts; a -chloroisovaleric acid may be obtained by treating isovaleric acid with chlorine under similar conditions in the temperature range 100-130 DEG  C.  The monochloro product may be isolated or the reaction mixture used directly for chlorination to the dichloro compound.  The salts may be prepared by treating the acid with the base in ether or a lower alkanol in the temperature range 10-70 DEG C. and the sodium, potassium, calcium, magnesium, barium, strontium, nickel, copper, zinc, cadmium, iron, aluminium, ammonium, methylammonium, ethylammonium, diethylammonium, triethylammonium, butylammonium, dodecylammonium, ethanolammonium diethanolammonium, triethanolammonium, monoethanol - di - isopropanolammonium, anilinium, naphthylammonium, diphenylammonium, piperidinium, pyrrolidinium and pyridinium salts are mentioned.

Class 39(i) A cathode ray tube of the type having a flared envelope and a transparent end face is provided with an external transparent shield of a synthetic resin covering at least the end face so as to provide protection against the effect of implosion of the tube when in use, which shield, or a frame supporting the shield, extends around the periphery of the end face and overlies a part of the side of the tube envelope so as to be supported by the flared part of the envelope. A space may be left between the shield and the end face of the tube and filled with a transparent liquid or jelly. To improve the contrast ratio the shield may be coloured, preferably a neutral grey, or it may have a light-absorbing film or coating over its inner or outer surface. The shield may be of the material known by the Registered Trade Mark " Perspex " and may be shaped by using the tube as a male mould. A flange may be left on the finished shield and provided with fixing holes to assist in supporting the cathode ray tube. The shield, or its securing frame if one is used, may be shaped so as to spring over the region of maximum diameter of the envelope and may be clamped or cemented to the envelope.

Title: Tailstocks for lathes and the like
Inventor: WOOD FRANK
IPC: B23B23/00
Filed: 1955-10-11
Abstract: 823,845. Lathe details. ARNFIELD Ltd., J. & E. Jan. 11, 1957 [Oct. 11, 1955], No. 28991/55. Class 83 (3). A tailstock for a lathe &c. is of the type provided with spring means for taking up the expansion that occurs in a workpiece when being machined. The centre 3 is carried in a non-rotatable sleeve 2 fed by a rotatable spindle 4 screw threaded at 5 where it connects with the sleeve. A compression spring 12 is interposed between a collar 11 on the spindle and the inside of the housing. When the centre is fed forward by rotation of the spindle and meets the resistance of the work, spring 12 is compressed as the spindle is forced back, and a trip 13 secured to the spindle operates a switch 14 which stops the motor (not shown) driving the worm 7. The trip 13 engages a projection 15 on the switch mounting if the spring 12 fractures, and thus prevents the work being completely released. Drive 7 is reversed for retraction of the centre, and the motor is stopped by a finger 8 on the sleeve engaging a switch 10. Forward movement of the sleeve is halted when there is no work in the machine, by the finger 8 and switch 9. An electrical interlock may be provided so that the tailstock cannot be released while the machine is running and a workpiece is held by the tailstock.

Diamond powder can also be included with the BN. The hot pressing is preferably effected in a reaction vessel 14 comprising salt, talc, pyrophyllite or Al 2 O 3  cylinder 19 in which is positioned graphite resistor 20 and salt liner 21. The reaction vessel is seated in a die 12 and the charge assembly comprising the BN and cemented carbide enclosed in a Zr, Ti, Ta, W or Mo sheath is placed in the cavity 31 of the reaction vessel. A number of separate charges may be loaded in the sheath, each charge being separated by spacers of the sheath metal.
