Title: Improvements in or relating to rotary fluid cleaners
IPC: B04B5/00
Filed: 1967-08-11
Abstract: 1,137,309. Centrifugal separator. N. D. S. WILLIAMS. 11 Aug., 1967, No. 36924/67. Heading B2P. In a centrifugal separator for removing impurities from engine oil the rotor 13 is adapted to be rotated independently of any driving force obtained from the oil to be cleaned and includes a number of separate containers 13 mounted in a stack on a common shaft 9, each container being connected to an adjacent container through one or more openings so that the oil flows sequentially from one container to another in the course of separation. The shaft 9 may be at any angle to the horizontal and is supported in bearings . 6, 7 secured in apertures in a casing 1 and has a central passage 10 through which oil is fed through a union 18 and from which the oil escapes via ports 11, 12 into the lowermost chamber, as shown. The containers 13 are separated by washers 21 and are held together by the force exerted by a spring 15 acting between fixed collars 14. The arrangement is such that when the centrifugal force or the oil in the containers nears the rupture strength of the containers, oil pressure on washers 21 acting through ports 22 causes the containers to separate from the washers against the constraint of spring 15, thus allowing oil to discharge into the interior of the casing 1. A baffle 16 is mounted in the lowermost chamber above ports 17 in the base therefore. The shaft 9 may be rotated by an electric, hydraulic or air motor or by being coupled to a fan or water pump drive of an engine either directly or by means of a flexible shaft. When the rotor is stationary, oil fed through the shaft 9 into the lowermost chamber passes under the baffle 16 through the ports 17 into the interior of the casing 1 and is returned to the engine sump. When the rotor rotates, the oil is flung from the upper surface of the baffle towards the wall of the lowermost chamber against which the impurities separate out. The oil passes upwardly from one chamber to another and clean oil is discharged through the uppermost openings 20 into the casing 1 to 'be returned to the engine sump.

Abstract: 523,280. Indicating faults. NALDER BROS. & THOMPSON, Ltd., CARR, J. L., and SHACKLETON, H. Dec. 30, 1938, No. 37840. [Class 37] Faults in a distribution circuit are indicated by means of a rectifier carrying a current proportional to the current in the circuit or in a neutral lead common to a number of circuits and connected to inductive means by which a current depending on the rate of change of the current in the rectifier operates an indicating instrument. The secondary winding of a current transformer 1 in the neutral 2 of a three-phase system 3, 4, 5 is connected to a rectifier bridge 6 which supplies the primary winding 7 of a transformer, of which the secondary winding 8 is connected to a moving- coil measuring instrument 9. The moving member 11 engages contacts 10 when the current from the secondary 8 rises to a predetermined value in either direction and thus closes the circuit of an indicating or signalling device at a generating station or sub-station. A large current change in the neutral taking place rapidly is thus indicated, giving warning of conditions resulting in one or more phases being open circuited, for instance, when one or more of the fuses 14 are blown.

As the ball joint is recharged with fresh lubricant under pressure through the fitting 30, old and dirty lubricant present in the fitting is discharged therefrom between the lips 26 which separate to permit the lubricant to pass. The shank 38 of the ball stud is secured to a vehicle steering knuckle 25. Lubricant flows from the nipple 30 past the ball stud and into a space 23 within the resilient cover 10. The cover 10 retains the lubricant and shields it from dirt and comprises a flexible annular portion 11 with opposite sealing edges in flange 12 and in portion 14, respectively, the flange 12 being secured to the socket 33 by a metal band 41 and a spring 42 and the portion 14 engaging the stud shank 38.

Title: Means for indicating the liquid level in diving bells of dynamo-electric machines working under liquids
IPC: G01F23/24
Filed: 1930-12-18
Abstract: 366,663. Indicating and regulating liquid levels. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Dec. 18, 1930, No. 38214. Convention date, Jan. 27. [Class 123 (i).] A dynamo-electric machine working under liquid, e.g. a pump unit having a motor 11 and pump 12, is provided with a bell 14 surrounding the suction pipe 15. The bell contains a tube 16 preferably of quartz filled with hydrogen, and having an iron wire resistance 19 within. The resistance is connected by wires 20 to one arm of a Wheatstone bridge, and is heated by the passage of a current to an extent determined by the amount of immersion of the tube 16. The resistances of the other arms of the bridge are so proportioned that the galvanometer deflection is proportional to the level of liquid in the bell, and information is thus given as to the working conditions of the submerged motot, so that compressed air may be supplied to the bell if required. The resistance 19 may alternatively be connected in series with a galvanometer or electric lamp, which are affected by the variation in current due to a change of resistance, or the latter may control a relay which automatically regulates the supply of compressed air to the bell. In the Specification as open to inspection under Sect. 91 (3) (a) the bell 14, Fig. 3 (Cancelled) contains a closed U-tube 30 provided with an electric lamp 33 at the upper end. The bend of the U-tube contains mercury, and the space in the limb 31 contains hydrogen. The expansion of the hydrogen due to the heating of the lamp 33 normally maintains the mercury level between the contacts 36, 37, but if the liquid rises in the bell the limb 31 is cooled and the contacts 36, 37 are bridged so that a signal or the like can be operated. The apparatus can also be used for indicating the liquid level in inaccessible containers. This subject-matter does not appear in the Specification as accepted.

In a disc brake having a floating caliper 3 and directly and indirectly actuated friction pads 12, 11, the directly actuated pad is arranged to move towards the disc with a motion comprising both translation along and rotation about the axis of the pad to provide a selftightening effect. The pads 11, 12 are provided with backing plates 13, 20 having tongues 13<SP>1</SP>, 20<SP>1</SP> engaging in support members 14, 21. Member 14 has slots 15, 16 of different depths, one of which is manually selected, according to the wear of the pad, to align with and abut one arm 17 of the caliper. A biasing spring 19 is provided. The member 21 co-operates with ball- and-ramp mechanism 24-28 and is rotatable by a lever 22 connected to a brake lever by linkage adjustable for pad wear. A return spring 29 acts on the lever. The sliding surfaces of the mounting bracket 5 and the caliper 3 are provided with grease retained by a seal 10. A tapped hole 35 in the caliper allows a screw to be inserted to centralize the caliper when the brake is being fitted. The screw is then removed to allow the caliper to float, shortened and used as a grease retaining screw. Brackets for fitting the brake to the front forks of a motor cycle are described.
