Abstract: 575,836. Air cleaners. LEYLAND MOTORS Ltd., and WARING, G. J. April 4, 1944, No. 6268. [Class 8 (ii)] Air from an internal-combustion engine inpinges on an oil bath, flowing down through a channel bounded on one side by a baffle 10 terminating at or about the oil level, and under the edge of this baffle then rising through a second channel bounded internally by a baffle 11 which dips a little more deeply below the oil surface; as the rate of air flow increases the oil level is depressed outside baffle 11 and rises within this baffle till it overflows the top and increases contact with the air. Further increase of speed causes the air to flow under the lower edge of baffle 12 to a channel bounded by baffle 13 the oil overflowing this baffle at still higher speeds. The air is cleaned by passage through an annular labyrinth 6 from which oil flows back to the main body. A bell 3 secured to the outlet pipe supports the laby- 'rinth.

Title: New or improved precision registering or indexing mechanism for machine tool parts such as milling machine tables, jig boring tables, milling machine dividing heads, andthe like
IPC: B23Q16/02
Filed: 1944-04-06
Abstract: 572,529. Indexing. HANCOCK, W. A. April 6, 1944, No. 6454. [Class 83 (iii)] Dividing or indexing mechanism for machine tools such as milling-machines and jig-boring machines, comprises a circular series of rolls or balls of uniform diameter closely juxtaposed, a detector roll or ball supported by a longitudinally movable rod, and urged by a spring against the circular series of rolls or balls, a worm-wheel annulus fastened to the indexing table or head and a worm engaging with the annulus. A circular work-table d is rotated by means of an annular worm-wheel b bolted to the underside of the table and engaging a worm c operated by a hand wheel r. The worm-wheel revolves in a groove or channel a<2> in a base member a and, if desired, the groove may be filled with lubricant. To a depending central hub d<1> of the table d is keyed a member f which serves as a holder for the circular series of rollers h. In the example described, twentyfour rollers are employed and are held in position by a ring j, one roller of the series being held by a bolt h<1> against movement around the member f. The series of rollers is engaged by a smaller roller o mounted at the end of a rod m longitudinally movable through two ball races carried in a slideway k and urged forwardly into contact with the rollers h by means of a spring incorporated in an indicator or gauge p whose operating rod p<1> engages a hardened end m2 of the rod m. As shown in Fig. 3, rotation of the rod m is prevented by means of a ball n engaging a longitudinal V-groove in the rod and in an adjustable race bar n. The indications of the gauge pointer will show when the roller o is exactly in the bight between two rollers h and also when it is exactly on the crest of one of the rollers h, thus giving forty-eight accurately adjustable positions for the table d. Intermediate readings of the gauge may also be used if desired. Clamping plates (not shown) carried by the base a may engage the wormwheel b to hold the table in any required position. Detent means may be provided for holding the rod m out of contact with the rollers h for rapid coarse adjustment. The wheel b may have 180 teeth and the pitch of the worm c may be such that one revolution gives a onetooth feed or a two degree rotation of the table. A graduated dial q which rotates with the worm shaft co-operates with a vernier scale on a fixed dial t.

Abstract: 848,685. Electric copying-machines. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 19, 1957 [March 2, 1956], No. 6553/56. Class 38 (6). [Also in Group XXXVI] In apparatus for cutting a profile according to a predetermined pattern in which the centre of a milling cutter is moved according to a recorded programme, an analogue computing device for determining correcting signals is incorporated in the interpolator to enable a cutter of different radius from that for which the programme was made to be used. In Fig. 2 the signals from the record are represented by x and y. From these dx dy subsidiary signals - and - are derived and fed dt dt to mutually-perpendicular stator coils 7 and 8 of a resolver. The output from rotor coil 9 excites a motor 11 via an amplifier 12 to drive-shaft 10 so that the output from coil 9 is reduced substantially to zero and hence the tapped inductance sine and cosine potentiometer 13 (Fig. 3, not shown) is positioned in accordance with the angle # (Fig. 1). This potentiometer 13 is excited by means of a reference voltage from a further potentiometer 15 which is adjusted according to the value of #r which is the difference between the nominal radius and the actual radius of the cutter. The outputs from potentiometer 13 are respectively added to the x and y signals by means of transformers 18 and 19 to form the modified signals x<SP>1</SP> and y1 for controlling the operation of the tool. A mathematical explanation of the manner in which Fig. 2 functions is given in the Specification. Specifications 796,994, 830,461 and 848,411 are referred to.
