Abstract: 612,725. Grinding-mills. COMBUSTION ENGINEERING CO., Inc. Feb. 18, 1946, No. 4984. Convention date, Aug. 25, 1944. [Class 59] In a mill wherein the material is pulverized in a rotating bowl and the fine material is removed by an air current passing upwardly between the bowl and an outer casing, uniform distribution of the air around the bowl is ensured by fixed vanes arranged between the bowl and the casing. As shown, rollers 21 are urged by springs 27 against a grinding ring 20 in the bowl 17 which is rotated by gearing 19. The sleeves 24 carrying the rollers 21 project upwardly through the top face of the casing 16, means being provided to prevent the escape of air. Air is supplied through a duct 37 to the space around the bowl 17, and turbulence in the passage past the edge of the bowl is prevented by fixed vanes 38 which may be welded to the casing and are arranged at an angle of about 45 degrees to the vertical in overlapping relationship. Vanes are arranged in the upper part of the mouth of the duct 37 in continuity with the vanes on the casing, the vanes in the duct being carried on a baffle plate 39 arranged tangentially to the bowl, and on a plate secured to the upper side of the duct. The spaces between the vanes are such as to permit large pieces of waste material, e.g., tramp iron tc pass to the space beneath the bowl for removal to a discharge shoot 36 by scrapers 35. Oversize particles, of materials being pulverized. are deflected back into the bowl by members 16a, and a further separation of coarse and fine particles is effected centrifugally at the ports 32 and pipe 33, the coarse particles passing through the opening 34 back into the grinder. The bottom opening between the casings 30, 31 is non-annular in section and is of considerable area, so that relatively little air passes upwards through the opening 34.

Patent GB-511503-A (GB)
Title: Improvements relating to the tuning of radio receivers
IPC: H03J5/14
Filed: 1938-02-18
Abstract: 511,503. Electric control systems. COLE, Ltd., E. K., and MARTIN, A. W. Feb. 18, 1938, No. 5063. [Class 40 (i)] [Also in Group XL] In a radio receiver having press-button motor tuning and manual tuning, the motor circuit is opened automatically during manual tuning. In the arrangement shown, M and L are two pushbuttons which energize motor 1 from the supply transformer 4 over a split contact device 7, 8, 9, of known kind which arrests the motor at the position of the tuning shaft corresponding to the required station. With this arrangement, if a button is left depressed and the operator turns the tuning knob by hand, the motor is again energized and must be overcome by the manual control. The present invention avoids this by providing that any push-button depressed (as shown at 6) first energizes the motor momentarily to cause a holding contact 5 to be closed by the motor armature, and then the contact 6 breaks so that the motor runs until its circuit is interrupted by 7 and the contacts 5 then reopen. Manual operation of 'the tuning element can no longer energize the motor, as contacts 5 and 6 are both open. The latter contact is energized by the hinged latch-bar on the pressbutton frame. Specifications 474,682, [Group XL], and 497,774 are referred to.
