Patent GB-632527-A (GB)
Title: Method of and apparatus for de-gassing lubricating grease
IPC: C10M177/00
Filed: 1947-07-01
Abstract: <PICT:0632527/III/1> <PICT:0632527/III/2> <PICT:0632527/III/3> <PICT:0632527/III/4> Entrapped air is removed from lubricating grease by dividing the grease into small streams or particles and subjecting the streams or particles to a vacuum.  In the illustrated example, grease which has been cooled to below its melting point and which may be a mixture of two greases having different soap bases, is delivered to a hopper 1 from which it is conveyed by the screw-conveyor 2 to a pump 3 which forces it through conduit 4, fine-mesh screen 5 and conduit 7 to the T 8, where the grease is divided into two streams 9 and 10 which are forced into opposite ends of the mixer 13.  The mixer 13 is provided with a series of perforated baffle-plates 14 and 15 staggered so that the grease is forced to travel in a sinuous path in its passage through the mixer to the conduit 16.  The grease passes through conduit 16 and the perforated plate 18 to the evacuated chamber 17.  In its passage through the plate 18 the grease is divided into small streams and the liberation of air trapped in the grease thereby facilitated. The air thus released is withdrawn from the vacuum chamber 17 through the perforated plates 24 and 25 and conduit 20 by means of vacuum pump 21.  The grease is allowed to accumulate in chamber 17 for 2 to 10 hours, the vacuum pump 21 is then stopped, the vacuum in chamber 17 broken and the grease pumped out through conduit 28 by the pump 29.  Plates 24 and 25 act as barriers to prevent the passage of any grease into the suction conduit 20 in the event of the accumulated grease in the chamber 17 foaming up.  The process is said to be suitable for the de-aerating of a grease made from an oil having a viscosity of approximately 85 S.U.S. at 210 DEG  F., the grease containing 4 per cent of soap and being a mixture of 75 per cent of a soda base grease and 25 per cent of an aluminium base grease, both cast in pans.ALSO:A mixer used in an apparatus for deaerating lubricating greases (see Group III) comprises a longitudinal vessel provided with a series of perforated staggered baffles and with means for feeding the material to be mixed simultaneously to the opposite ends of the vessel and for withdrawing it from the centre of the vessel.  The baffles are so arranged that the material to be mixed travels in a sinuous path through the mixer.

Interlocking.-All the points and signals for a given route are operated by means of a single route lever which operates a sliding member to close electric contacts connecting up the relays or magnets for setting-up the route. The sliding member B is connected to a contact-carrying bar D by a cam slot c; the contacts d<1>, d<2>, are arranged to connect the source of energy to the leads k<1>, k<2> which extend throughout the locking frame and supply current to the double-coil relays K which control a set of points. The relay K is of the type deseribed in Specification 24003/10 having interlocking armatures. The locking slide B has a check locking bolt withdrawn by the magnet E. When the route is to be set, the lever A moves the slide B to position 2, and the magnet K<2> is energized and closes contact k<2> in the circuit to the motor M. The points being fully operated, the switch m<4> is reversed and current is supplied to the relay L<2> which closes contact l<1>. Current then passes to the contacts g<2> and magnet E, releasing the lever A, which is then moved to position 4 so that current passes to magnet H controlling the signal circuit. The signal is then set to clear by its motor I. On replacing the lever A, it is stopped at position 3 until the relay T is energized by the passing train closing its circuit. At position 1 the lever is stopped until the signal is restored to danger position. Lamps or other indicators r<1>, r<2>, r<3>, r<4> are provided to indicate the condition of the apparatus. For each point, a lever P is provided, interlocked with the route levers, to enable the points to be operated individually.

Abstract: 613,312. Pipe couplings. THOMAS, P. E., and STERLING INDUSTRIES, Ltd. June 18, 1946, No. 18277. [Class 99 (i)] In a self-sealing pipe coupling of the spigot- and-socket type, wherein, on coupling, a fixed valve part of one member displaces a movable valve part of the other member so as to open. the pipes to fluid flow, and on uncoupling, each member is automatically sealed against outlet of fluid, the predominating, material of the coupling is a light metal or light metal alloy, while one of the co-operating valve parts is made of iron, steel, bronze or other hard metal heavier than the said light metal or alloy. Fig. 1 shows two members A and B coupled together by a nut C. Member A has a movable seating formed by a ring 24 in sealed slidable relation with the body part 1a of the member, and a fixed valve part 16 attached to the member A by the spider 15. Member B has a movable valve part 9 and fixed seatings 3, 4. The assembled coupling is shown wherein the ring 24 has been displaced by the action of the seating 3 of member B against the spring 23 which normally holds the ring 24 against the seat 17 of the valve part 16. Valve part 9' is normally held against the seating 3 of member B through the intermediary of a resilient ring 11, but in the coupled: position shown it is displaced against the action of the spring 14 by the pressure of valve part 16 of member A on a metal seating ring 12 attached to the resilient ring 11 and thus to the valve part 9. This part 9 is carried on a spindle 7 slidable in a tube 6 attached to the member B by a spider 5. When the nut C is unscrewed, the parts are automatically restored to closed positions by means of the springs. Preferably, the ring 24 is made of the hard, heavy metal so that it can be machined to give an accurate seating surface resistant to wear. The invention is described as being applicable to the couplings of Specifications 585,038 and 591,743.
