Title: Self-lubricating bearing
IPC: F16C33/04
Filed: 1965-08-17
Abstract: 1,106,794. Bearings. EBAUCHES S.A. 17 Aug., 1965 [17 Aug., 1964], No. 35138/65. Heading F2A. A self-lubricating bearing material comprises a first mixture 6 of a self-lubricating lamellar material and a ductile metal, and a second mixture 7 of a self-lubricating material and a binder. The first mixture is divided into granules 6 which are contained in the second mixture 7. The crystallites of the self-lubricating lamellar material of the second mixture are smaller than those of the first. A suitable self-lubricating lamellar material is a metallic sulphide, selenide telluride, or halide in which the metal is Ti, Cr Co, Cu, Zn, Zr, Nb, Mo, Ag, Cd, In, Sn, Sb, W, or U, or the material is graphite or a nitride, e.g. boron nitride. A suitable ductile metal is Sn, Cd, In, Pb, Cu, Ag, Zn or An or an alloy of one of these with another metal. A suitable filler is a polyurethane or epoxy resin or an inorganic binder. In Fig. 2 the material 10 lines a bush 9 and a self-lubricating lamellar material 11 is adhered to a shaft by a metal layer 12 or is formed directly on the shaft surface.

Title: Improvements in electric cable systems
IPC: H02G15/26
Filed: 1938-12-02
Abstract: 522,030. Cable systems. OKONITE-CALLENDER CABLE CO., Inc. Dec. 2, 1938, No. 36172. Convention date. Dec, 8, 1937. [Class 36] In a cable system comprising a sheathed or non- sheathed insulated conductor disposed in a fluid-filled pipe and terminating in a fluidfilled terminal member connected to the pipe the fluidfilled spaces within the pipe and the terminal member communicate through automatic means, such as a spring-loaded valve, which prevents movement of fluid from the pipe to the terminal member but allows fluid to flow in the reverse direction when the pressure within the terminal member exceeds that in the pipe by a predetermined value. The transmission to the terminal member of excessive pressure which may build up in the pipe, and the building up of excessive pressure in the terminal member, are thereby avoided, whilst drainage of the system of fluid in event of damage to the terminal member is also prevented. As shown in Fig. 1 a partition 26, making a fluid-tight connection with the sheath of a cable 6 passing from a fluid-filled pipe 8 to a fluid-filled pot-head 10, separates the two fluid-filled spaces, the partition having a port 34 containing a check-valve 36 which permits fluid to pass from the pot-head into the pipe when the pressure within the former exceeds a predetermined value. A needle valve 32, which is normally closed is provided to allow the pot-head to be initially filled with fluid from the pipe. In a modified construction the partition is of conical form and is employed with a non-sheathed cable. Fig. 3 shows a construction wherein the pot-head 51 is carried by a fluid-filled riser 52 connected to a pipe 53 leading from a semi-stop joint 55 in the cable system. A check valve 61 provided in the end wall 58 of the joint casing allows fluid to pass from the pot-head and riser into the joint casing when the pressure in the riser exceeds by a predetermined amount the pressure in the joint casing, whilst a manually operable valve 59, which is normally closed and is of construction similar to that described in Specification 462,287, is provided for controlling movement of fluid from the casing. Specification 409,678 also is referred to.

Title: Improvements in or relating to high pressure steam accumulator locomotives
IPC: B61C1/04
Filed: 1946-11-27
Abstract: 640,235. Power generating systems. RUTHS INTERNATIONAL ACCUMULATORS, Ltd. Nov. 27, 1946, No. 35207. Convention date, Aug. 14, 1940, [Class 122(iii)] [Also in Group XXXI] In a high pressure steam accumulator locomotive in which accumulator steam passes through a hand-operated high pressure throttle valve, a receiver and a low pressure throttle valve to the locomotive engine, the throttle valves are connected by coupling means so that both valves are moved in the same sense, e.g. to open or to close. The coupling means may be so arranged that the low pressure throttle begins to open and is fully open before the high pressure throttle and the low pressure throttle begins to close later and is fully closed after the high pressure throttle. As shown in the Figure, the steam accumulator is connected to a shut-off valve 2 and the high pressure throttle valve 3 mechanically coupled to the low pressure valve 6 between which steam passes through a superheater 4 and the receiver 5. An auxiliary, reducing valve 8, preferably automatic, admits steam to the receiver 5 for operating auxiliaries of the locomotive when the valve 3 is closed. An automatic reducing valve 7 is interposed between the valve 3 and the superheater to maintain the receiver pressure close to the allowable maximum. The operating gear for the valves 3, 6 may be fitted with a hydraulic damper to operate in the opening stroke and a friction brake to prevent vibrational movement. A pressure gauge for the receiver 5 is preferably placed in or near a window in the line of the driver's vision. Specification 522,279 is referred to.

It carries fast and loose driving belt pulleys 21, 22, pulleys 15, 18 for belt drives 16 and 19 (Fig. 1, not shown) to the leather roller and pusher board crankshaft respectively; it also carries, inwards of the machine frame 13, an eccentric 23 coupled by a connecting rod 24 to a crank 25 on the beater shaft 26. Since the interior of the machine is substantially empty, ginned seed can drop uninterruptedly into a conveyer or receptacle beneath the machine.

In another embodiment, Figs. 14 and 15 (not shown), air is inducted through one end of the cylinder and ejected through one end of the piston. In a further embodiment, Figs. 16 to 18 (not shown), air is inducted through lateral ports (66) in the cylinder and ejected through one end of the piston, said ports being covered with perforated plates (67) to support the vanes. Yet another embodiment, Figs. 19 to 23 (not shown), is usable as an expander and comprises lateral inlet and outlet ports (86, 87) in the piston and sliding blades, or fixed fins, on the piston to effect radial sealing between the vanes in the region where the piston is closest to the cylinder, the piston and cylinder being synchronized by intermeshing pegs (93). The vanes may be made of silicon rubber reinforced with carbon fibres and may have an axial-sealing bead at each end furnished with PTFE inserts (2), Fig. 1 (not shown), to reduce friction.

Title: A process for separating chlorosilanes
IPC: C07F7/20
Filed: 1955-12-19
Abstract: Diorgano- and triorgano-chlorosilanes are separated from trichlorosilanes and silicon tetrachloride by adding to a mixture thereof formamide or dimethyl formamide in an amount at least equivalent to the total trichlorosilane and tetrachloride.  These latter compounds form crystalline complexes of the general formula RnSiCl4-n.XHCONR12, where X is 2 to 4, R1 is methyl or hydrogen, n is 0 or 1, and R is a monovalent hydrocarbon radical containing less than 7 carbon atoms or a halogenated monovalent hydrocarbon radical. The complexes may be removed by filtration or decantation or the di- and tri-organosilanes may be distilled off.  The reaction may be effected continuously by passing the silanes through a column containing the amide absorbed on a carrier such as charcoal or asbestos, or by extracting the trichlorosilane and/or SiCl4 from the mixture by liquid interchange.  In the examples: (1) dimethyldichlorosilane is separated from methyltrichlorosilane by adding formamide and distilling.  The residue is MeSiCl3.4HCONH2. (2) Me2SiCl2 is separated from SlCl4 by the addition of dimethyl formamide.  (3) Ne3SiCl is similarly separated from SiCl4.  (4) Vinylmethyldichlorosilane is separated from vinyltrichlorosilane using dimethyl formamide, the complex having the formula ViSiCl3.3HCONMe2.  (5) Phenylmethyldichlorosilane is separated from phenyltrichlorosilane, the complex being PhSiCl3.HCONH2.  (6) Chlorotrifluorocyclobutylmethyldichlorosilane is separated from chlorotrifluorocyclobutyltrichlorosilane using dimethylformamide, the complex being <FORM:0777319/IV(a)/1>ALSO:Complexes of silicon tetrachloride and trichlorosilanes with formamide or dimethyl formamide are formed by adding the amide to a mixture of chlorosilanes containing the tetrachloride and/or trichlorosilane. The complexes have the general formula RnSiCl4-n.XHCONR12, where X is 2 to 4, R1 is H or methyl, n is 0 or 1, and R is a monovalent hydrocarbon or halogenated hydrocarbon radical, and are crystalline compounds insoluble in di- and tri-organosilanes, thus permitting the separation of these compounds (see Group IV (a)).  The examples disclose the preparation of SiCl4.3HCONMe2 and other complexes of organotrichlorosilanes.
