Filed: 1929-02-25
Abstract: 329,404. Browne, C. Feb. 25, 1929. Clutches, free-wheel.-A universal joint, applicable to gramophone and other low power drives, for connecting two shafts one of which is wholly supported in bearings whilst the other is supported at one end in an end bearing and at the other end on the adjacent end of the first shaft length, comprises interengaging cupped and rounded or pointed parts between the adjacent shaft ends and a tubular resilient drive-transmitting member gripping the shaft ends with or without positive connection thereto. The Joint takes lateral and end thrust and the rounded orpointed part may be formed on one of the shaft ends to engage a hemispherical or conical cylindrical hollow in the adjacent end. The resilient member may be a rubber tube or a coil spring. As shown in Fig. 1, there is a spherical member- C and a coil spring D, which when not positively connected to the shafts allows slip or overrunning of the driven shaft. In this form, end thrust will be in part due to contraction in length of the spring. As applied to a gramophone, Fig. 4, an electric motor G drives a worm shaft H' supported in a screw-adjustable end bearing J and a flexible joint D<1>. In order to adjust the position of the worm H' relative to its wheel K to obtain correct mesh, the motor is pivoted on a vertical axis in a U-shaped frame F<1>. and can be locked in the adjusted position. The Provisional Specification states that the spring D may be soldered to the shafts.

Title: Improved treatment of lead chloride and the application thereof to the treatment of lead ores or the like
IPC: C01G21/00
Filed: 1924-03-15
Abstract: Lead chloride or oxychloride or a double salt containing one of these salts is converted into lead sulphite by treatment with a sulphite or bisulphite or with an oxide or carbonate and sulphur chloride.  In an example, lead chloride is suspended in ammonia solution and sulphur dioxide is passed in.ALSO:Lead chloride or oxychloride or a double salt containing one of these salts is converted into lead sulphite by treatment with a sulphite or bisulphite or an oxide or carbonate and sulphur dioxide.  After the separation of the lead sulphite, the mother-liquor may be divided, a part being treated to recover the chloride such as ammonium chloride, and the rest being made up for use in the next operation by adding the necessary materials.  The treatment of the lead chloride may be by a counter-current process. The process may be employed in conjunction with the treatment of lead zinc ores by known processes.  For example, a lead-zinc ore may be roasted so as to convert the lead into sulphate and the zinc into oxide; the zinc is extracted as bisulphite, and the lead is extracted from the insoluble residue by a chloride solution, which may be acidified; the lead chloride is recovered from the solution by dilution, and is then treated with the zinc bisulphite solution, and if there is not enough zinc present, zinc oxide or carbonate is added and sulphur dioxide is passed ino the mixture; after the separation of the lead sulphite, zinc chloride solution remains.  Or the lead-zinc ore may be treated with a fused chloride to chloridize the lead while the zinc sulphide, which is unattacked, is separated and roasted to oxide, which together with the lead chloride is suspended in water and treated with sulphur dioxide.  Examples describe the treatment with sulphur dioxide of a suspension of magnesium carbonate and lead chloride and of a suspension of lead chloride in ammonia solution.

Title: Improvements relating to lever operating mechanism particularly adapated for vehiclebraking systems
Inventor: MASON FRANCIS RICHARD
IPC: B60T7/04
Filed: 1958-03-04
Abstract: 910,747. Vehicle brakes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 27, 1959 [March 4, 1958], No. 6945/58. Class 103 (1). [Also in Group XXIV] In a lever-operating mechanism, for example for vehicle brakes or electrical switch gear, the mechanical advantage is automatically increased on a predetermined increase in resistance to movement. In Fig. 1, an actuating lever 1 pivoted on a shaft 2 is connected by a link 3 to one end of a lever 4 having its midpoint connected to an output member comprising an hydraulic cylinder 5, and its other end connected by a link 6 to a follow-up member 7 which is also pivoted on the shaft 2 and is normally urged by a spring 8 into contact with the actuating lever. Initial depression of the actuating lever against a low resistance will cause the lever system to move as a whole, but on increase of resistance the force of spring 8 will be overcome and a stop 11, which normally holds a spring-loaded pivoted rack 13 out of engagement with a pawl 14 on the member 7, will be caused to slide down an arm on the member 7 by virtue of a connection with a lever 10 integral with the actuating arm, so that the pawl 14 engages the rack 13 and holds the member 7 stationary, thus increasing the mechanical advantage of the lever 4. The lever 1 is returned under the action of a spring 16. In Figs. 2 and 3, an actuating lever 1 is keyed to a shaft carrying sun-wheel 21 and a disc 24 having a projecting lug 25, which is urged by a spring 36 into contact with a lug 26 of an annulus 23 rotatable in a casing 32. Providing the resistance through the system is less than the force of the spring 36, the sunwheel 21, annulus 23, planet wheels 22 and a planet carrier 28, connected to an output lever 27, move as a whole, but with increasing resistance the spring 36 yields, the lugs 25, 26 move out of contact and a pin 33 on the disc 24 allows a spring-biased pawl mounted on the annulus 23 to engage ratchet teeth 31 in the casing and hold the annulus against rotation so that the epicyclic train increases the mechanical advantage of the system. Releasing the actuating lever will allow the disc 24 to rotate and cause the stud 23 to disengage the pawl from the rack and allow the gear to return to its initial state as a solid unit.
