Title: Improvements in or relating to regulating transformers
IPC: H01F29/06
Filed: 1935-04-09
Abstract: 453,569. Transformers. SHEVLIN, J. T., 15, South Street, Finsbury, London.-(Naamlooze Vennootschap Machinerieen-en Apparaten Fabrieken Meaf; 30, Croeselaan, Utrecht, Holland) April 9, 1935, No. 11413/36. Divided out of 446,455, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 19, 1935. [Class 38 (ii)] In a transformer regulated by movement of a current collector over the turns of the regulating winding, the collector is in the form of a copper ring d surrounding the winding c and contacting with the bare turns thereof at a point which may be varied along the whole length of the winding, the ring being embraced at intervals along its circumference by iron cores f which serve to increase its self inductance. The ring d is carried by eccentrically-mounted spindles h geared together for simultaneous rotation whereby the point of contact between the ring and winding is varied. The ring may be guided in its axial displacement either by the turns of the winding or by screw-threads on the spindles h of the same pitch as the winding. Two collector rings movable in opposite direction may be used as the terminals of the regulating winding. The ring or rings may include a number of turns surrounding each of the auxiliary cores f.

Title: Improvements in or relating to box crimping of tow or yarn bundles
Inventor: HEINJNIS JAMES WATT IJSBRAND
IPC: D02G1/12
Filed: 1965-03-18
Abstract: In a stuffer-box crimper, the feed rollers are so profiled as to deform a tow or yarn bundle (passing therethrough and forced thereby into the compression chamber) and thus impart to the tow &c., a toothed, zig-zag, undulating, or curved profile extending in a plane parallel to the rollers' axes.  The resultant complex, three-dimensional crimp may be further promoted by moving the tow &c., to and fro between the rollers in an axial direction thereof.

Title: Improvements in or relating to fluid pressure system unloading valves
IPC: F16K17/10
Filed: 1959-04-08
Abstract: 918,102. Fluid-pressure servomotor control systems. HYDRAULIK A.S. April 8, 1959 [April 12, 1958], No. 11843/59. Class 135. A pump unloading valve for a fluid-pressure system including a fluid-pressure motor 13, Fig. 1, controlled by a manual control valve 12 and pressure and return conduits 11, 14 connected respectively to the outlet and inlet sides of a pump 10, comprises a valve body 15 having inlet and outlet chambers 16, 17, a check valve 20 and an unloading valve 22 controlling communication between the chambers. The valve 22 comprises a main valve member 25, Fig. 2, slidable in a fixed sleeve 24 and loaded by a light spring 30 and a pilot valve member 33 slidable in an axial bore in the main valve member, loaded by an adjustable spring 37 and guided in the base 29 of a second fixed sleeve 28 supported by a body cover 31. Pressure of the liquid in the inlet chamber 16 is transmitted through an interchangeable orificed plug 43, Fig. 3, the axial bore 33a and a lateral port 44 in the pilot valve member to a space 24a to act on the larger rear face of the main valve member to urge the main valve member assisted by the spring 30 leftwardly to close lateral ports 26 in the sleeve 24. On pressure in the inlet chamber overcoming the loading of the spring 37, the pilot valve member 33 moves rightwardly to unseat a conical shoulder 34 and unmask lateral pilot valve member ports 45 and recesses 46 to allow the escape of liquid from the space 24a and rightward movement of the main valve member to uncover the ports 26 and unload the pump. Movements of the pilot valve member 33 to more or less unmask the ports 45 and recesses 46 will constantly adjust the pressure in the space 24a to maintain pump discharge pressure substantially constant. Interchangeability of the orificed plug 43 permits of variation in the time taken for the valve to be returned to its closed position.

Title: Improvements in and relating to the manufacture of condensation products from n-substituted carbazoles and ªÐ-nitrosophenol and its derivatives
IPC: C07D209/88
Filed: 1922-05-02
Abstract: The condensation of halogen-free N-substituted carbazoles, such as N-ethylcarbazole, with halogen-free nitrosophenols, such as p-nitrosophenol and its homologues, in the presence of a condensing agent is effected by bringing the reacting bodies together at a temperature below-10 DEG  C. and maintaining the same below -5 DEG C.; a temperature of -20 DEG  to -25 DEG  C. is preferred and is kept constant throughout the reaction.  One component may be added in a finely divided solid state to a sulphuric acid solution of the other or solutions of each may be mixed; the products are preferably isolated by pouring into dilute ammonia.  In an example N-ethylcarbazole is condensed with p-nitrosophenol at -20 DEG  C. The products yield sulphide dyestuffs of greater purity than those from indophenols prepared at higher temperatures. Specification 9689/09 is referred to.
