Title: Improvements in the manufacture of iron alloys of very low carbon content
IPC: C21C7/00
Filed: 1933-07-25
Abstract: In a process for the manufacture of iron alloys, particularly ferro-chromium and ferromanganese, with a very low carbon content but still containing a relatively high proportion of the reducing agent, such as silicon used in the reduction of the ores, the reducing agent is eliminated from the iron alloy by a violent intermixing of the molten metal with a very fluid molten slag capable of oxidizing the reducing agent present in the alloy.  The molten metal may be run rapidly from a considerable height, e.g. 2 1/2 to 3 metres in a thick jet into the slag or the metal and slag may be run simultaneously into a ladle.  The slag which is highly basic may be melted separately or may be run from the furnace in which the alloy was produced.  In the Specification as open to inspection under Sect. 91 it was stated that the intermixing may be effected by means of a gas injected into the mass of molten metal and fluid slag.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the forming of coils
IPC: H02K15/04
Filed: 1969-04-24
Abstract: 1,215,425. Winding stators, coiling helices. OFFICINE MECCANICHE PAVESI & C. S.p.A. and MECBAR S.p.A. 24 April, 1969 [1 Aug., 1968], No. 21104/69. Headings B3A and B2E. A method of winding a coil comprises winding successive turns of a coil on a former having at least one axially tapered outer peripheral surface so shaped that the tension in the wire causes the turns formed on the former to be displaced axially over the tapered surface towards its narrowest part, causing the turns to pass from the former to a coil transfer or inserting tool. A tubular mandrel 22 is located within a mandrel 21, to which it is splined, and the wire 6a passes through the mandrel 22 to a rotary winding flyer 7 which is connected to the mandrel 21 for rotation therewith. The former 5<SP>1</SP> is positioned axially with the required tapered portion disposed so as to receive wire from the flyer. The mandrels are then rotated to drive the flyer and as the turns are formed they slide on to rods 10 of a transfer tool 9 mounted on a rotary head 36. Successive concentric coils are wound by advancing the former 5<SP>1</SP> and mandrel 22 by means of an actuator 27. When the winding is completed, expelling rods 14 are advanced by an actuator 28 and the last turns on the former 5<SP>1</SP> are pushed on to the transfer tool 9. The former is retracted together with the rods 14 by the actuator 27 and the tool 9 is indexed through an angle corresponding to the angular separation of adjacent sets of rods 10, which corresponds with the number of coils of the stator, whereupon a further set of coils is wound. On completion of a full revolution of the tool 9, the wire 6a is severed and the head 36 rotated through 180 degrees to bring a transfer tool 9<SP>1</SP> into the working position, while the windings are removed from the tool 9. The former may be provided with only one tapered surface where groups of coils are not required. A ferrule (16) may be provided on one of the rods 14, which, when extended by advancing the rods half a step, catches the wire of the last turn and thus allows winding to proceed in the opposite direction, Fig. 5 (not shown).

Abstract: 294,539. Aktiebolaget Separator- Nobel. July 25, 1927, [Convention date]. Void. [Published under Sect. 91 of the Acts]. Mineral oils, purifying.-In refining mineral oils and distillates by treatment with a liquid such as sulphuric acid, the mixed oil and refining agent are separated in a centrifugal machine. The refining agent may be admixed with the oil in fractions, which are separated in a centrifugal machine before addition of a further fraction. Oil and sulphuric acid are admitted continuously to a tank 4 fitted with a stirring device 12 through valves 9 from tanks 5, 6, provided with overflows 7, 8, float-regulated valves or other devices to maintain a definite level, and the mixture is discharged through valves 13 leading by a pipe 14 to centrifugal separators. The mixture may be effected by passing the liquids through emulsifying devices comprising revolving discs, atomizing nozzles, &c. The operations are carried out in the absence of air, either by the use of closed vessels or by passage of inert gas. The subsequent washing and treatment with alkali, if necessary, may be carried out in a similar manner. The liquids leaving a distillation apparatus may be refined before cooling.

Abstract: 571,118. Gas-blast switches. ENGLISH ELECTRIC CO., Ltd., BROWN, J. K., PRESCOTT, J. A., and ROWLAND, F. G. Dec. 16, 1943, No. 21116. [Class 38 (v)] The exhaust gas from a nozzle contact 2 is passed through a tube 4 into a chamber 6, the top 5 of which has one or more small-bore tubes 7 having a replaceable small-apertured vent cap 8. A .further cover 9 and perforated wall 10 may be added for use outdoors. The arrangement economizes blast-gas because once the chamber 6 reaches maximum pressure, which it may be arranged to do after only two cycles of current, flow ceases notwithstanding the inlet valve may still be open. The venting from chamber 6 may be delayed by a valve operated in response to opening of the breaker or series isolator, or to operation of a protective device controlling the breaker. The arrangement is also applicable to the operating mechanism of circuit-breakers.

Title: Improvements in or relating to delay action or timing devices, particularly suitablefor use in connection with electric control apparatus
IPC: H01H47/18
Filed: 1936-07-31
Abstract: 474,310. Electromagnetic switches and controllers. SCOTT, W. H. July 31, 1936, No. 21253. [Classes 38 (iii) and 38 (v)] In an electromagnetic timing device of the character described in Specification 370,148, each magnet core is provided in addition to the retarding slug with a pilot and holding coil arranged for successive excitation in the operation of the device, the pilot coil being adapted to effect an initial movement of the armature, when free, and the holding coil being adapted to ensure protracted retention of the armature in the position into which it is moved under the influence of the pilot coil. As shown in the Figure employed in the control of a reversible motor, the pilot coil 5 or 5<1> is energized on movement of the controller to the " forward " or " reverse " positions in series with a variable resistance 11 or 11<1> and contactor 10 or 10<1>. The current is not strong enough to operate the corresponding contactor end if the armature is held in the opposite position the pilot coil cannot attract its armature. If, however, the armature is free it is at once attracted and just before it touches the core 1 or 2 causes the engagement of contacts 8, 8<1> and 9, 9<1>. This connects the corresponding holding coil 7 or 7<1> directly across the mains in series with the corresponding contactor 10 or 10<1>, the increased excitation of the latter causing its operation and closing corresponding contacts 16, 16<1> or 17, 17<1> to establish an alternative energizing circuit for the timing device for steps of the controller subsequent to the first step. If now the control circuit is broken a delay which may amount to several seconds occurs before the armature is released from the corresponding core owing to the action of the copper slug 6. Thus, if the controller is moved in the opposite direction before this delay ceases and the armature is released, the opposite weakly-energized pilot coil will be unable to attract the armature to produce a change-over operation and thus sufficient time is allowed for the motor to be braked to rest before the reverse running circuit is completed. This delay is protracted by reason of the slow dying down of the flux initially created by the pilot and holding coils 5 and 7 and the consequent enhanced value of the eddy currents in the member 6 tending to maintain such flux. Should the coils be re-excited after an interval, for example, for inching the motor in the same direction, any delay is avoided as the armature 3 is either already held by the corresponding core or is free to be pulled on to this core immediately.

Abstract: 592,182. Altering physical structure. BAILEY, R. W., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Nov. 2, 1944, No. 21489. [Class 83 (iv)] Stretching and shrinking hoops.- Cylindrical or substantially cylin drical annular metal forgings of sub stantial dimensions are strain hardened by being subjected to circumferential extension or com pression or both, through the medium of a relatively thin-walled hydraulically expanded shell, while maintaining its cylindrical or substantially cylindrical form. Fig. 1 shows an apparatus for circumferentially extending an annular forging or casting 1, comprising a central cylindrical block 4 and upper and lower cover members 2 and 3 having axial flange portions 2a, 3a formed with conical faces between which the work is clamped. The conical faces take up the axial contraction or expansion of the work consequent upon a circumferential extension or compression. The expanding pressure is applied by means of hydraulic fluid forced through a duct 7 in the block 4 and acting on the work through a relatively thin shell 6 of annealed copper, soft iron or steel, welded to the block 4 at its ends as indicated at 6a. To prevent damage to the shell, the corners of the axial portions 2a, 3a of the covers are rounded and rounded fillets 8 are secured to the edges of the work. An outer annular cylinder 5 may be provided and may carry a flexible shell for subjecting the work to compression (Fig. 3, not shown). In a modified form, the central portion of the shell 6 may comprise an annulus of rubber cemented at its ends to relatively short tubular metal members welded to the circumferential edges of the cylinder. Alternatively, the pressure may be applied through a doublewalled annular rubber member 6e shown in Fig. 5. In another form, the double-walled member may be of metal of bellows formation. In order that the apparatus may be readily adjustable for work of various axial lengths, the covers 2, 3 may be replaced by members in screw-threaded engagement with the outer wall of the cylinder 4 as shown in Fig. 7. Alternatively, or in addition, the ends of the axial extensions 2a, 3a of the members 2, 3 may be screw-threaded as at 20 to receive annular shoes 19.
