Title: Apparatus for controlling the motion of a rotary member
IPC: F16H37/00
Filed: 1964-09-18
Abstract: 1,026,918. Epicyclic gearing. NUOVA SAN GIORGIO S.p.A. Sept. 18, 1964 [Sept. 18, 1963], No. 38292/64. Heading F2D. [Also in Division D1] A drive mechanism, particularly applicable to the control of the vertical movements of spinning machine carriages (see Division D1), includes a planetary gear unit driven through a one-way clutch, the arrangement being such that the transmission ratio is different for forward and reverse drive. As shown, the ring and eyelet carriages are operated by bands 34, 38 respectively connected to discs 33, 37, the former being connected to the output sun pinion 31 of the planetary gear, of which the input sun pinion 5 is driven by a pulley 3 on an input shaft 4 through a jamming roller clutch 21. The sun pinions 5, 31, which have slightly differing numbers of teeth, e.g. forty-nine and fifty respectively, are meshed by spaced identical planet pinions 25 carried by a yoke 27 mounted on a central idler shaft 1. The yoke also carries a rod 28 on which is mounted the arm 29 of a brake band 24 engaging the drum 23 of clutch 21. When the pulley 3 rotates in the direction F clutch 21 and band 24 lock the gear solid, the carriages thus being operated at the same speed. When a band C is slackened to release pulley 3 yoke 27 tends initially to rotate faster than input sun pinion 5 until a pin 12 on a disc 13 is arrested at the end of a slot 7 in a stop disc 6 to hold the clutch drum 23 stationary. Yoke 27 is thereupon held by band 24 and owing to the differing numbers of teeth on pinions 5, 31 disc 33 rotates slightly less in the reverse direction and the ring carriage is thus given the desired increment of lift. The extent of lift may be varied by circumferential adjustment of stop member 6 by a control knob. At the end of the wind, to facilitate doffing, the eyelet carriage is held in its raised position by a pawl 50 engaging a recess 51 in a member 39 integral with disc 37.

Title: The production of manganese hydroxide
Inventor: BARENT MARK
IPC: C01G45/02
Filed: 1956-12-20
Abstract: Liquors containing manganous salts are brought to a pH of 8.0-8.5, filtered and subsequently pure manganous hydroxide precipitated therefrom by adding a basic oxide or hydroxide whereby the pH is raised to not greater than 9, the precipitation being performed in the presence of an ammonium compound.  The oxide or hydroxide must be capable of giving a pH value of at least 10 when added to water and must not form an insoluble salt with any acid radical present in the liquor.  Specified precipitants for the manganous hydroxide are oxides and hydroxides of alkali metals (e.g. sodium) or alkaline earth metals (e.g. calcium), magnesium, ammonium and organic bases: with chloridecontaining liquors, any of these may be used; with sulphate-containing liquors alkaline earth hydroxides cannot be used. The ammonium salt content need not be equivalent to more than 1 per cent of ammonia in the liquor and is preferably added after the first filtration.  As starting liquors there may e.g. be employed the product of oxidation of aniline with manganese dioxide ore and sulphuric acid, after separation of benzoquinone, or a liquor obtained from the oxidation of ferrous chloride with manganic oxide. In one embodiment a liquor containing one or more ammonium compounds, e.g. a sulphate is first neutralized at a pH of 4 with lime to remove excess acid and precipitate iron and calcium sulphate; the mixture is preferably filtered and is then further treated according to the invention.  The liquor from which the bulk of the manganese has been precipitated may be treated with a water-soluble carbonate and the precipitated manganese carbonate returned to a fresh batch of the original liquor for treatment in accordance with the invention.

Title: Method and Apparatus for Crimping Electrical Connectors
IPC: H01R43/048
Filed: 1967-08-24
Abstract: 1,169,293. Stamping. DIAMOND DIE & MOLD CO. 24 Aug., 1967 [21 Nov., 1966], No. 38984/67. Heading B3Q. A method of crimping electrical connectors to conductors comprises continuously decreasing the rate of increase in the crimping pressure until a maximum crimping pressure is attained, slightly reducing the pressure and again increasing it to the maximum before releasing the connector. Apparatus for carrying out the method comprises a ram 106 suspended by toggle links 76, 78 from a stroke-displacement screw (88), Fig. 5 (not shown). A second set of toggle links 66, 70, connected between the first and a fixed point 62, are operated by a connecting-rod 72 driven by a pin 60. This is mounted on a crankshaft web 58 formed as a cam for operating a connector-feed, through a spring-pressed follower 124. The crank-shaft 30, Fig. 4, is driven through a one-revolution clutch by a motor 24. One part of the clutch is formed by openings in a gear 28 driven by the motor-pinion 26, and the other by a dog 38 slidable in a collar 34 fixed to the shaft. The dog is normally held against the pressure of a spring 44 by a lever 50 which may be raised, to release the dog, by energization of a solenoid (54), Fig. 6 (not shown), for example by discharge from a condenser. Location of the toggles is such that the central pivot 74 of links 76, 78 passes through the in-line position and slightly retracts the ram before the links 66, 68 are straight. Thus, a re-strike operation results as the links 76, 78 again straighten for the return stroke of the ram. The dog 38 is withdrawn by a cam on the lever 50 and arrested by engagement with an abutment (56) on the lever. Specification 1,151,182 is referred to.

Abstract: 1,100,007. Dynamo electric machines. AMPEX CORPORATION. 14 Sept., 1965 [6 Oct., 1964], No. 39120/65. Heading H2A. In a control system for a stepping motor, the motor windings are energized sequentially under control of a system of logic circuits responsive to forward and reverse command signals and to further signals indicative of the shaft position. Fig. 1 (not shown) relates to a motor, e.g. of the type described in Transactions of the American Institute of Electrical Engineers, Application and Industry, March, 1962, having a permanent magnet rotor and coupled via a clutch or gearing to the capstan of a tape-recording transport system. The shaft position is determined by means of a toothed wheel carried by the shaft co-operating with a pair of lamps and photo-cells so as to provide four signals indicative of four discrete shaft positions. Alternatively, the shaft position may be determined by means of a disc having alternate magnetic and non-magnetic sections. The signals indicative of the shaft position are fed to a system of AND, OR gates (Fig. 3, not shown), which steer command pulses relating either to forward or reverse rotation, to four respective stator windings so that the motor increments one step for each command pulse. An OR circuit and inverter is used to provide holding currents in the absence of both forward and reverse command signals. Alternatively, continuous rotation in either direction may be achieved by use of D.C. command signals. Each command signal pulse may be terminated by means of an additional photo-electric cell and lamp co-operating with the toothed shaft position sensing disc. Each stator winding is provided with a resistance-capacitance circuit which increases the build up of current in the winding.
