Abstract: 1,109,991. Seals. BRISTOL SIDDELEY ENGINES Ltd., and SIR F. WHITTLE. 9 July, 1965 [10 July, 1964], No. 28663/64. Heading F2B. A shaft-sealing assembly particularly for welldrilling equipment comprises inner sleeves 26, 27 and an outer sleeve 31 mounted between a tubular shaft 20 and a casing 22, the sleeve 31 being formed with a face sealing surface 34 which is engaged by a counter face sealing surface 35 on a ring 36 rotatable with the sleeve 26 to form a high-pressure seal which is separated by an inter-seal space 41 from a low-pressure seal consisting of a pair of lip seals 45 arranged in a sleeve 46 axially slidable in the sleeve 31, the low pressure seal being urged against the pressure in the space 41 by a leaf-spring 49 and oil leaking from bearing cavity 10 into the space 41 is returned by a pump system comprising plungers 50 operating in cylinders 51 formed at equal angular spacings in a flange part of the sleeve 31, the plungers being urged against a cam surface 52 formed on a flange part of the sleeve 27. The plungers 50 are normally held out of engagement with the cam surface 52 by the head portion 53 of the sleeve 46 but when oil leaks from the bearing cavity 10 into the space 41 the low pressure seal is driven to the right against the spring 49 sufficiently far to give the plungers a working stroke which just returns the leakage to the bearing cavity. The pumps each have inlet and outlet bores 56, 57 respectively leading to the seal surface 34. The seal surface 35 is provided with alternate recesses on its inner and outer edges and these recesses cooperate with the bores 56, 57. In a modification, Figs. 8 to 12 (not shown), any lubricating oil escaping from the bearing cavity into the inter-seal space is returned via a groove 75 in the outer sleeve. Means are provided for bypassing the pump inlet valves to prevent the entry of grit past the low-pressure seal. Instead of the pump cylinders being fixed in a sleeve in fixed relation to the casing, they may be fixed in a sleeve in fixed relation to the shaft. In another modification, Fig. 13 (not shown), the pump cylinders are formed in one of the face-seal rings. In a further modification, Fig. 14 (not shown), a valve-controlled liquid transmission is provided between a cam follower piston and a pump piston.

Title: Reinforced carbon bodies
Inventor: MARIN G R
IPC: C01B31/00
Filed: 1971-06-22
Abstract: 1358869 Reinforced carbon bodies CARBORUNDUM CO 22 June 1971 [22 June 1970] 29139/71 Heading C1A [Also in Division F2] A reinforced carbon body comprises an underlying network of reinforcing carbon fibres and a matrix of carbonized binder, the fibres of the network being arranged so that they wind spirally around an axis passing through the centre of the body and are caused to overlap irregularly by compressing the wound fibre in a direction parallel to the winding axis before carbonizing the binder. The perimeter of the body may be indented and the winding of the fibre conform to these indentations. The body may be an annulus when the internal or the external circumference may be indented or both. The body is preferably a disc which is adapted to be used as a brake disc which may accordingly have an indented or a scalloped periphery. The reinforcing carbon fibres used may have been coated with from 10% to 30% by wt. of a refractory material, e.g. silicon carbide. Other additives, e.g. B, Nb, Si, Ta,T,W and Zr, borides of Nb, W, Si, Ta, Ti, and Zr, carbides of B, Nb, Si, Ta, Ti, W and Zr and nitrides of Al, B, Nb, Si, Ta, Ti, W and Zr, particularly tungsten diboride, may be incorporated in the carbon body preferably in an amount of 0À25-5% by volume of that portion of the body containing the additive. WB 2  is particularly favoured at those points of the disc that are subject to friction from adjacent discs, and boron is favoured at those areas not subject to such friction. The carbon fibre may be used in the form of a cloth, the initial width of the spirally wound cloth being wider, e.g. in a ratio of 1À25 to 1, to 3 : 1, than the final carbon body. The structure of the body may be arranged so that the fibre density throughout any radially irregular body is approximately the same. This may be achieved by inserting extra carbon, e.g. as fibre into those areas of extra radius. In a brake disc these areas are preferably those in frictional contact with adjacent discs. Alternatively fibre may be removed from those locations of lesser radial depth. In another embodiment, comprising an annulus, the inner periphery of the annulus is shaped so as to balance the fibre distribution in the non-uniform thickness of the radial section. Furthermore, the fibre density may be increased at given points in the body by causing the fibres to fold at these points.

Filed: 1926-11-22
Abstract: 261,790. British Thomson-Houston Co., Ltd., (Assignees of Jackson, J. A.). Nov. 21, 1925, [Convention date]. Master control systems; electric braking.-In controlling a slip-ring induction motor working hoists, lifts, and the like, acceleration in hoisting is obtained by progressively shortcircuiting secondary resistance which is also used, under automatic conditions, to retard the lcwering; further retardation in lowering is obtained by reversing the torque and ultimately short-circuiting all the secondary resistance. The arrangement shown in the drawing has a manually operated master controller C and contactors 15 - - 18 for short-circuiting resistances R<1> - -R<4> in the secondary circuit of the induction motor 10 under the control of two current-limit relays CLR<1>, CLR,<2> acting alternately. During hoisting the resistance is short-circuited in steps as the right-hand segments of the master controller are brought into their successive contact positions, the progression being subject to pauses due to the action of the current limit relays. For lowering the load the master controller is moved to the point e, passing over the points g and h without effect, whereupon the lowering contactor is closed and the motor drives the load slowly in the downward direction with all resistance in the secondary circuit. If with the controller on the point e the load should overhaul the motor and drive it as a generator, a centrifugal switch 14 automatically sbort-circuits the resistances R<1> - - R<4> one after another. The controller is next moved to the point f, where it brings about the closing of all the resistance contactors. To slow down the load considerably, a backward movement of the master controller to the point e reverses the power connections, and still further backward movements short-circuit the resistance to increase the retarding torque up to stopping point.
