Title: Improvements in or relating to method of and apparatus for classifying particles
IPC: B04C1/00
Filed: 1949-04-21
Abstract: 675,365. Centrifugal separators. SHARPLES CORPORATION. April 21, 1949 [April 24, 1948], No. 10598/49. Class 23 In a cylindrical zone having sectional areas decreasing towards the centre, particles are classified by the opposing action of centrifugal force and the drag of an inflowing fluid. The end walls of the zone are so shaped that the opposing forces on a particle of critical size are balanced at any radius. The Specification gives formulae for the shape of the end walls which are ideally parabolic although conical or spherical approximate forms may be used. As shown in Fig. 1 the particles to be classified are introduced by pipes 14 into main airstreams which enter the zone 13 tangentially. Adjustable blades 22 are provided at each entry to regulate the flow to the zone. The lighter particles and air leave the zone through an axial pipe 16, and the heavier particles fall into a hopper 10. In the modification shown in Fig. 3 particles from a hopper 30 are urged by a feed screw 31 through a pipe 33 to the classifying zone 13. Air cleaned by a filter 41 traverses an annular passage 43 where it is whirled by vanes 51 and passes through the zone to carry the lighter particles through the central outlet 35. The lighter particles are separated from the air by a cyclone or filter 38, the air outlet of which is connected to a fan 37 which sucks the air through the apparatus. The heavier particles are collected in a container 49. In a further modification the feed for the air to the zone may be through tangential pipes.

Patent GB-107034-A (GB)
IPC: C10G11/00
Abstract: 107,034. Rostin, H., and Forwood, G. F. May 15, 1916. Mineral oils.-Unsaturated hydrocarbons are converted into saturated hydrocarbons by bring- ing them, together with sulphuretted hydrogen, into contact with a substance, such as copper, which generates nascent hydrogen from the sulphuretted hydrogen. Unsaturated hydrocarbons formed by cracking may thus be hydrogenated during the cracking operation. For example, vapours of heavy oils are passed, together with sulphuretted hydrogen, over copper heated to above 500‹ C., a saturated cracked hydrocarbon being obtained. Unsaturated hydrocarbons are hydrogenated without cracking by treatment at 300‹ C. The sulphuretted hydrogen may be obtained by cracking oils containing sulphur, or by passing hydrogen, produced say in cracking oils, over copper or other sulphides. Accordingly, the operations of saturating hydrocarbons with nascent hydrogen, and regenerating the copper and the sulphuretted hydrogen, may be effected alternately in the same apparatus.

Abstract: 993,860. Regulating. BORG-WARNER CORPORATION. March 20, 1962 [March 27, 1961], No. 10711/62. Heading F1B. A fuel injection pump control rod 50 is controlled by a cam 12 connected to intake manifold and atmospheric pressure responsive devices 32, 42, the cam surface having a depression 16 for completely cutting off the fuel when the cam follower 17 engages therein e.g. at overrunning. The atmospheric pressure responsive device 42 may comprise a diaphragm enclosing a space 41 subject to a reference vacuum provided by a pump 46, or it may comprise an aneroid bellows. The cam 12 is carried on a carriage 19 which rolls on a guide rail 20. During normal running conditions the cam follower engages the inclined portion 21 of the cam to set the fuel supply in accordance with manifold vacuum. When, at over-running, the manifold vacuum exceeds the normal idling vacuum, the cam moves so far to the left that the follower 17 drops into the depression 16 and the fuel supply is cut off. The step on the depression 16 prevents return of the follower 17 to the normal running portion 21 of the cam until the vacuum reaches a lower value than that at which the follower engages in the depression 16. Specification 943,200 is referred to.

[Also in Groups XXIV and XXXVIII] A master compass M, including a north-seeking element, normally drives a repeater R and a slave repeater SR, having no indicator, through an amplifier A, e.g. as in Specification 647,206, [Group XXXVIII]. When the aircraft carrying the compass is to effect a turn, switches 10, 11 are opened to disconnect the master compass, and the slave repeater SR is clutched electromagnetically to the frame of a gyro G so that during the turn, the slave repeater functions as a master compass to drive the repeater R, being connected to the amplifier input over a switch 12 closed as 10, 11 open. The electromagnetic clutch and the switches 10, 11, 12 may be actuated manually or automatically by the appropriate turn control element of the aircraft, and are returned to normal on the completion of the turn. In a modification, Fig. 2 (not shown), the slave repeater is dispensed with and the gyro frame adapted to be clutched to the repeater R. The gyro used has no precessional control and such a gyro may be used as a gyro compass, Fig. 4, driving its indicator I through a friction clutch FC. Deviations of the indicator I due to gyro wander are corrected periodically, e.g. at halfminute intervals, when a switch 30 is closed to connect a repeater R to a master compass M through an amplifier A. The repeater then corrects the setting of the indicator I, the clutch FC slipping meanwhile. Specification 647,235, [Group XL (c)], also is referred to.
