IPC: H02K13/00
Filed: 1926-09-02
Abstract: 257,935. Urbinati, M. Sept. 3, 1925, [Convention date]. Brushes; brushholders. - A rotating brush-gear for a dynamo-electric machine comprises brushes s bearing upon the vertical plane surface of the commutator c and pivoted to arms b, the other ends of the arms being pivoted to a sleeve m on the shaft a. The brush-pressure is given by the component z<1> of the centrifugal force, and this pressure may be regulated by axial movement of the sleeve m. According to the Specification as open to inspection under Sect. 91 (3) (a), the commutator surfaces may be slightly conical, and both plane surfaces may be utilized. This subject-matter does not appear in the Specification as accepted.

Abstract: 770,206. Cables; cable joints. SIEMENS BROS. & CO., Ltd. July 22, 1955 [July 23, 1954], No. 21610/54. Classes 36 and 38 (1). In a high-voltage cable, a smooth equipotential surface is provided between the stranded conductor and the surrounding plastic insulation by applying a layer of conducting or partly conducting paint or varnish to the inner surface of the insulation and/or the conductor surface as the insulation is extruded over the conductor. The paint or varnish may comprise a suspension of carbon or metallic powder in a mineral oil, silicone fluid or synthetic organic polymer. In a joint between two such cables, a layer of conducting material is applied to the jointed conductors to waste the equipotential surfaces of both cables before the joint is insulated, and this layer may either comprise a paint or varnish, or a helicallyapplied tape of rubber, silicon rubber, polyvinyl chloride, polythene or polyethylene terephthalate coated on one or both sides with such paint or varnish.

Abstract: 399,960. Distributers for manures, seeds, &c. CARGILL, A. W., Waitawa, Canterbury, New Zealand. Aug. 10, 1932, No. 22422. Convention date, Sept. 3, 1931. [Class 6 (i).] Apparatus for distributing lime, manure, mixtures of manure and seeds, &c. comprises a hopper 1 adapted for mounting upon or incorporating in a vehicle or implement and having its two longer sides converging towards the bottom, a rotary spindle 2 extending longitudinally through the lower part of the hopper, a series of right and left-hand wire helices 5, 6 mounted alternately end to end on the spindle to rotate therewith and co-operating in pairs to convey the material to the spaces between the two helices of each pair, and outlet openings 7 in the bottom of the hopper vertically below the spaces. The spindle 2 carries a gear wheel 4 which is driven from a travelling wheel or other rotating part. The openings 7 may be formed in a tube 8 within which is a tube or round rod 9 having corresponding through openings 10. The tube 9 is angularly adjustable by a handle 11 for adjusting the effective areas of the openings 7. The helices have radially bent ends 12 secured in radial holes in the spindle 2 by cross pins. Each pair of helices may be made from a single length of wire with a loop 14 at the junction, which loop sweeps across the corresponding opening 7 at each revolution. Alternatively the helices may be made separately and arranged so that the radial ends of both pass across the outlet at each revolution. A boss 15, Fig. 4, having radial projections 16 may be mounted between the two helices of a pair and may be driven by the engagement of the loop 14 with one of the projecting arms 16. The spindle may be steadied at intermediate points by upper bearings 17. Broadcasting or drilling appliances may be mounted below the outlet openings 7.

Abstract: 1,262,082. Endless conveyers in mines. MAVOR & COULSON Ltd. 10 July, 1969 [11 May 1968], No. 22452/68. Heading B8A. [Also in Division E1] In a loader in which material ahead of the loader is transferred across a ramp 1 to a conveyer 2 by the chain-mounted flights of oppositely operating, endless conveyers 3, 4, the frontal runs of the conveyers 3, 4 can be independently or simultaneously varied in length whilst the tensions of the chains are maintained constant. To permit of such adjustment of a conveyer 3, 4, the outer, front and rear guide sprockets 7, 9 for the flighted, endless chain of the conveyer are mounted at opposite ends of a lever 11 pivoted at a point nearer its rear end than its front end in a guide roller 12 slidable in a longitudinally extending guide channel 14 in the ramp and the rear sprocket 9 is so constrained by a guide 10 that, when the link is caused, by a ram 18 extending between the link and the ramp, to swing about the axis of the guide roller 12 then the sprocket 9 will move along a path at right angles to the channel 14. The mounting of the drive sprocket 16 and the coaxially associated drive motor of each of the conveyers 3, 4 on and eccentrically of a circular plate rotatably supported in the face of the ramp facilitates initial fitting and tensioning of the conveyer chain.

The moulding wheel 1 may have cavities 9 in its periphery. The moulding material is injected through a channel 15 in the mouth portion 13 of the nozzle 12. The insert 17, which may be a plurality of wires or bands of metal or plastics material, is fed through channels 16 provided with seals 18. In order to locate the reinforcing wires 17 correctly they may be fed, as shown in Fig. 3, through an opening 20 in the nozzle mouth 13, an additional opening for the moulding material being provided at 21. Alternatively, the teeth 8 on the wheel 1 may have projections (19), Fig. 6 (not shown), to locate the wires 17. The moulding wheel 1 comprises a central profiled disc 6 and two side discs 7 provided with shoulders (10) for locating the endless band 2. In Figs. 4, 5 (not shown) a corrugated endless band 22 is used to produce a toothed belt which also has teeth at the rear side. In Fig. 7 (not shown) the endless band (24) has openings (25) covered by caps (26) at the side remote from the moulding wheel thereby producing teeth on both sides of the belt. The invention may be used for making driving belts, conveyer belts or the like, the inserts being filaments, wires, cords, ropes or bands of plastics material or metal.

Title: Improvements in plant for generating, storing and supplying acetylene gas
IPC: C10H15/12
Filed: 1928-08-07
Abstract: 321,234. Simonis, O., and Liquid Air, Ltd. Aug. 7, 1928. Solid supply to liquid; removing sludge from generators.-To prevent access of air to an acetylene generator during the charging with carbide or the removal of sludge, the carbide hopper has a double closure including an internal sell-closing valve operated bv the weight of the carbide charge, and the sludge valve is associated with means for supplying gas to the generator during the removal of sludge. As shown, the carbide hopper b is supported on a water container a and is closed at the top by a lid c and also by a valve: m pressed upwards by a spring n. The spring n is supported by a tube n<1> suspended from the top of the hopper. The hopper is charged from a bucket p, Fig. 3, closed at the bottom by a valve q, the bucket being superposed on the hopper after the lid c has been removed. The weight of the carbide then depresses the valves q, m, but the valve m returns to its seat as soon as the bucket empties or is removed. The carbide is discharged intermittently from the hopper by a bucket wheel f driven through mechanism (not shown) operated by the rise and fall of the gas holder or bell. The unnecessary free spaces in the hopper are filled with concrete r moulded so as to provide guiding surfaces for the carbide. The carbide is received by a screen t and the evolved gas passes through a pipe h, water seal j, and pipe k to a holder; a siphon l acts as a safety device. The sludge is withdrawn through a valve u mounted in a stem u<1> which passes through a tray v containing water. The valve u is pressed against its seat by a lever w and weight w<1>, and a link z connects the lever w with a cock y on a pipe x leading from the gas pipe k back to the generator. The arrangement is such that when the valve, u is opened and the sludge is discharged, acetylene flows back into the generator to maintain the pressure.
