Title: Improvements in the manufacture of moulded articles
IPC: H01B3/36
Filed: 1936-11-10
Abstract: In the preparation of moulded articles from heat-hardenable phenolic resin mixes, "non-volatile detrimental substances" as defined below are excluded, and the mixes or the moulded articles are heated so that the pressed articles have a dielectric loss factor, tan d , of less than 175 X 10-4 measured at 200 m. "Non-volatile detrimental substances" means such a proportion of one or more substances giving rise to dielectric loss and non-volatile under the conditions of the process, that the final product would have the factor tan d  equal to or greater than 175 X 10-4, measured at 200 m., in the absence of substances, e.g. water, formaldehyde, ammonia, which are volatile under the conditions of the process and would increase the dielectric losses in the product.  "Non-volatile detrimental substances" specified are fibrous filling materials (e.g. wood pulp or paper), stearic acid, castor oil.  Permitted fillers are mica, quartz, and plasticizers such as tricresyl phosphate and paraffin.  In examples: (1), (2) a cresol-formaldehyde resin and montan wax mix was heated before or after hot-pressing; (3), (4) a mix of cresol-formaldehyde resin, mica powder, and montan wax, with or without tricresyl phosphate is heated before hot-pressing. Specification 416,847 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the avoidance of the addition of volatile and non-volatile detrimental substances to such a degree that the pressed articles have a tan d  less than 175 X 10-4, and examples in which (a) a mix of cresol-formaldehyde, magnesium oxide, montan wax and tricresyl phosphate is heated before hot-pressing, and (b) articles prepared from a mix of cresol-formaldehyde resin, mica powder, montan wax, and tricresyl phosphate are after-heated. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to friction clutches
IPC: D05B69/22
Filed: 1959-09-10
Abstract: 913,905. Controlling clutches. BARRING- TON, J. L., and EMMANS, G. V. Dec. 12, 1960 [Sept. 10, 1959], No. 30864/59. Class 80 (2). The driven member of a clutch is stopped in a predetermined position on disengagement of the clutch in order, for example, to stop a sewing- machine with the needle either in or out of the material according to the work being done. A multi-plate clutch having friction plates c of copper and plates s of steel, is engageable to connect a driving pulley 1 to a driven sleeve 3 by a thrust-collar 7 having a cam face 8 for actuation by a nose on an arm 10. The arm 10 is fast with a sleeve 11 which is also fast with a treadle arm 13 and a stop-arm 18. The treadle arm 13 is depressed to engage the clutch and to remove a stop 19 on the arm 18 from the path of a projection 22 on a disc 21 fast with the driven sleeve 3. In the engaged position a roller 28 on a tail 18x of the arm 18 engages the top of a spring-pressed plunger 29. On release of the treadle 18 the arm 13 is urged upwardly by a spring 14, but is prevented from moving by a roller 24 carried by the end of the arm 18 engaging the periphery of a driven cam disc 25. When the roller 24 engages a recess 26 in the cam disc, the arm 10 disengages the clutch and stop 19 engages the projection 22 to stop the driven sleeve in a predetermined position. The roller 24 in the cam recess prevents rebound of the driven member, aided by the roller 28 riding off the plunger 29. If it is desired to stop the machine in both the needle in and the needle out positions two cam recesses and projections 22 are provided.

Title: Improvements in and connected with steam turbine installations
IPC: F01D1/02
Filed: 1920-11-02
Abstract: 171,036. Chittenden, J. P. Nov. 2, 1920. Axial-flow type; motor power plant; working- fluid supply.-In a motor power plant comprising a main turbine M and an auxiliary turbine A, the exhaust steam from the auxiliary turbine is delivered through special nozzles D into an intermediate stage of the main turbine. The nozzles D are so designed that they work with a pressure ratio equal to or greater than the critical value over a considerable portion of the range of working conditions. In this manner the exhaust pressure of the auxiliary turbine is to a large extent rendered independent of the pressure at the intermediate stage of the main turbine into which it is delivered so that the conditions in the auxiliary turbine may for a large range of load of the main turbine be practically independent of that load. Instead of the concentric arrangement of the nozzles D with the ordinary nozzles a segmental arrangement may be adopted, and although the turbines shown are of the impulse type the invention is not limited thereto.

Filed: 1929-10-14
Abstract: Benzanthronepyrazolanthrone derivatives.-Bromo Bzl.Pyl1-2.21-benzanthronepyrazolanthrones obtained according to the process of the parent Specification are condensed with such amounts of a single organic compound containing a replaceable hydrogen or metal atom attached to a nitrogen, oxygen or sulphur atom that substantially all bromine present in the initial material is replaced by the same organic residue.  The amino derivatives produced by this process may be further alkylated, acylated or condensed by means of acid or alkaline condensing agents.  The first condensation is preferably effected in presence of high-boiling diluents, acid-binding agents and catalysts such as copper, copper oxide, nickel, nickel carbonate and silver oxide.  The subsequent carbazolization may be effected by means of sulphuric acid to which manganese dioxide may be added, aluminium chloride alone or with common salt, or caustic alkali.  In examples, (1) dibromo-Bzl1-Py1-2.21 -benzanthronepyrazolanthrone (prepared according to Example 1 of the parent Specification) is condensed with 1-aminoanthraquinone (dyes grey), 2-aminoanthraquinone (dyes bluish-grey), 1-amino-4 - benzoylaminoanthraquinone or 1.4 - diaminoanthraquinone followed by benzoylation of the product (dyes greenish-grey); these products may be carbazolized by fusion with alcoholic potash, or by treatment with aluminium chloride with or not sodium chloride and an oxidizing gas present : (2) monobromo - Bzl.Pyl1 - 2.21 - benzanthronepyrazolanthrone (prepared by bromination in chlorsulphonic acid at 80-90 DEG  C. in presence of iodine as catalyst) is condensed with 1-aminoanthraquinone (dyes blue-grey to blue-black), and with phenol (dyes navy blue): (3) dibromo-Bzl.Pyl1 - 2.21 - benzanthronepyrazolanthrone (prepared according to example 5 of the parent Specification) is condensed with benzamide (dyes green-blue); substituted benzamides, naphthalene carboxylic acid amides, anthraquinone carboxylic acid amides or acid amides of higher molecular weight may replace benzamide; using p-toluenesulphonamide or potassium phthalimide products are obtained which may be saponified by acids to the free amino compounds: (4) the dibromo derivative of (1) is condensed with 4-amino-Bz.3.5-dichloroanthraquinone-2-1-benzacridone (2 mols.) (dyes green-grey); if this acridone (4 mols.) is condensed with a tetrabromo derivative (prepared by bromination of the benzanthronepyrazolanthrone in oleum in presence of a catalyst) a product dyeing olive shades is obtained.  Specifications 318,180, 324,079, and 327,734, [all in Class 2 (iii), Dyes &c.], also are referred to.  4-Amino-Bz.3.5 - dichloranthraquinone - 2.1 - benzacridone is prepared by treating the unhalogenated acridone in nitrobenzene in presence of iodine with chlorine, converting the 4.Bz.3.5-trichloro derivative to the Bz.3.5-dichloro derivative by means of reducing agents, nitrating the latter in nitrobenzene and reducing.
