Abstract: 1,066,876. Friction clutches; controlling clutches; springs. SOC. ANON. FRANCAISE DU FERODO. April 2, 1965 [April 3, 1964], No. 14125/65. Headings F2C, F2L and F2S. A diaphragm spring for a friction clutch (Fig. 1, not shown) has radial slots, forming spring fingers 23, which slots are each formed with an inner portion 22, adjacent the spring axis, having a lesser width than a second portion 40 formed adjacent, or extending from (Fig. 4, not shown), the spring pivot pin mounting holes 24, the arrangement providing improved contact between the spring fingers 23 and the contacting rib of a release member (27) (Figs. 1 and 7, not shown), the holes 40 additionally improving ventilation of the clutch. The rigidity of the spring fingers may be increased by deformed raised edges (41a) (Figs. 4 and 5, not shown) of enlarged ventilation holes extending from the mounting holes 24, or, by curving or cambering the levers 23 in crosssection. In Fig. 7 (not shown), the inner narrow portions (43) are punched out and completed by a sanding operation or a chemical, electrolytic or electro-chemical treatment to remove burrs. Clearance for the spring fingers may further be obtained directly, by retaining several slots cut out along their full length (Fig. 7, not shown). The diaphragm spring may be polished or ground to improve contact between the spring fingers and the release member (27). In Figs. 4 to 6 (not shown), the inner ends of the spring fingers have forged chamfers (42). The fulcrum rings (25), Figs. 9 to 11 (not shown), arranged one each side of the diaphragm spring may be mild steel closed strips or wires having their ends joined by a weld (45), the flash burr of which is limited to a square circumscribing the cross-section of the wire, the burr (45) being reduced to size by forging and trimming, after which the fulcrum rings (25) are cyanide hardened. Alternatively, the fulcrum rings may be nylon. The rotary outer race of the usual clutch-release ball-bearing (34), or carbon block, acts on the diaphragm spring fingers 23 through a ribbed case-hardened steel ring (27) secured to the clutch cover (17) by tangential strips (28) and carrying a bonded friction facing (33) of asbestos impregnated with resin or Teflon, or of nitrided steel.

Title: Improvements in or relating to the roasting of ores especially zinc sulphide ores containing lead and/or cadmium
IPC: C22B19/02
Filed: 1936-05-21
Abstract: 478,642. Treating ores. ROBSON, S., GYLES, T. B., and NATIONAL SMELTING CO., Ltd. May 21, 1936, No. 14386. [Class 82 (i)] In a method of sintering ores, particularly of zinc sulphide, on the travelling grate of a blast roasting apparatus, the charge is delivered on to the grate in three or more layers of such differing characteristics that on completion of the sintering an intermediate layer constitutes zone of cleavage enabling the comparatively pure sintered top layer to be separated from the bottom layer and delivered separately therefrom. The intermediate layer may be formed of inert material, or of material differing from that of the other layers as regards grain size, fuel value, or sulphur content. In the plant shown, the materials are fed to the grate by three shoots f, g, h, the contents of the pans are ignited at i, and the sintered product is met by the edge of an adjustably mounted knife c which divides the layers and discharges them separately at d and k. Specifications 119,223, 306,569, [both in Class 82 (i)], 358,039, and 433,861 are referred to.
Patent GB-586017-A (GB)
Title: Improvements in or relating to the stretch-breakage of artificial filaments
IPC: D02J1/22
Filed: 1944-07-28
Abstract: <PICT:0586017/IV/1> <PICT:0586017/IV/2> <PICT:0586017/IV/3> A tow of continuous cold-drawable and/or cold-drawn artificial filaments, e.g. nylon filaments, is converted into a spinnable top without destroying the continuity of the tow or the substantial parallelism of the fibres by subjecting the plurality of filaments to stretching and breaking between pairs of rolls, the stretch being simultaneously applied in varying amounts to the individual filaments.  Varying degrees of stretch are given to adjacent filaments, prior to breakage, by positioning one pair of rolls at an angle to the other pair, or by employing as the second pair rolls having frusto-conical surfaces.  As shown in Fig. 1, the drawing rolls 10, 12 are set at an angle to the retaining rolls 6, 8.  Rolls 6 and 10 are driven, the peripheral speed of 10 being greater than that of 6.  The reach between the retaining and drawing rolls varies in length from end to end and varying amounts of stretch are therefore applied to adjacent filaments in the tow passing therebetween, some of which are broken. The top passes from the drawing rolls through a condenser 14 and condensing rolls 16, 18.  Either the retaining rolls or drawing rolls may be set at right angles or at any other angle to the tow of filaments.  In a modification, Fig. 6, two pairs of drawing rolls 44, 46 are employed to one pair of retaining rolls 40, 42.  In Fig. 7, the drawing rolls 54, 56 have frusto-conical surfaces and their axes may be parallel to or set at another angle to the axes of the retaining rolls 50, 52.  The non-uniformities in fibre lengths may be further accentuated by varying the relative speeds of the retaining and drawing rolls or by intermittently stopping the retaining rolls. The tow may be made up of undrawn, partially drawn or fully drawn filaments or a combination thereof and may comprise filaments of varying denier. The tow may be subjected to a preweakening treatment such as by partial fusion or partial solution at intermittently spaced points.  A top is produced by the process from which yarn can readily be spun and in which the individual fibres have varying affinities for dyestuffs so that variagated shades may be obtained by dyeing in a single bath.  The Specification as open to inspection under Sect. 91 comprises also the application of the process to other filaments, whether cold-drawable or not, such as viscose rayon or cellulose acetate rayon.  This subject-matter does not appear in the Specification as accepted.
Patent GB-496270-A (GB)
Title: Improvements in and relating to processes for obtaining metals from their ores
IPC: C21B13/04
Filed: 1937-05-24
Abstract: Metals, especially iron, are obtained from their oxydic and sulphidic ores and compounds by causing the ores &c. to react at an elevated temperature with carbon or carbon monoxide or both and with lime in a closed reaction vessel, in which such a pressure is maintained that, at the reaction temperature, the partial pressure of the carbon dioxide formed is higher than the dissociation pressure of calcium carbonate so that the carbon dioxide former combines with the time forming calcium carbonate and the ore &c. is reduced to metal.  The mixture is first heated to a temperature sufficiently high to start the reaction which is then allowed to proceed without external application of heat.  In the case of magnetic metals, the metal-limestone mixture is cooled and the metal separated by a magnetic separator.  The limestone is then calcined to lime and used again.  The reaction vessel is preferably a heat-insulated pressure vessel.  In addition to iron, other metals, such as copper, lead, molybdenum, tungsten zinc and nickel may be obtained.

Title: Improvements relating to frequency filters

Abstract: 722,054. Electric filters. HOHNER AKT.-GES. M. June 9, 1952 [June 9, 1951], No. 14508/52. Class 40 (8). An electrical frequency filter having series and parallel branches is provided with switching arrangements whereby at least one impedance may be transferred from one branch to a gap in another branch previously short-circuited or occupied by another impedance, the gap left by such transference being shortoircuited or filled by another impedance. Each of various impedances 1 to 4 can be connected by switches either in the series branch 5-7 or in the transverse branch 7-6, the gap left in either branch being short-circuited. Associated with each impedance are six on-off switches, e.g. switches 8-13 with impedance 1. The closing of switches 8, 10 and 13 and opening of switches 9, 11 and 12 places impedance 1 in the series branch, while the reverse proceedure places impedance 1 in the transverse branch. In a modification the six switches are combined together in three change-over switches, excepting those associated with the last impedance, for which two change-over switches suffice, Fig. 2 (not shown). As shown in Fig. 3, element 24 in the series branch comprises an inductance 34 whose value may be altered by switching, and condensers 28, 29 and ohmic resistance 30 which may be switched in or out of the circuit. All components may be short-circuited by switch 39. By means of switches 26, 27 element 24 may be interchanged with element 25. The filter may be employed in electrically-operated musical instruments.
