Abstract: 546,679. Fountain pens. EVERSHARP, Inc. March 26, 1941, No. 4085. Convention date, July 1, 1940. [Class 146 (iii)] The feed-bar has an ink-feed passage in its upper surface, and a pocket 34, Fig. 2, in its underside for accommodating overflow ink conducted to it by slots from the upper forward portion of the feedbar. The slots are out of communication with the ink-feed passage, and the pocket has a restricted path of communication with the reservoir to lead excess ink back thereto when the pen is inverted. The bar is formed with ink-feed grooves 18, Fig. 5, on either side of a rib 19. The rib has a narrow kerf 20, Fig. 2, terminating short of the top of the bar, and is formed with a depression 19a, beyond which the top of the rib approaches the upper surface of the feed-bar, so as to leave a restricted air passage 23 to the reservoir. A second air passage is formed by a bore 21 communicating with a tube 24, which extends into the barrel and is formed with a curved leader-strip 25. In the sides of the feed-bar are formed upper and lower overflow recesses 28, 28, Fig. 1, which terminate within the barrel and are connected by passages 29a, 29b. The underside of the bar has grooves 30 separated by a wall 31, which is cut away to form the pocket 34. Diagonal slots 36 lead from the top of the feed-bar to the grooves 30. The forward end of the barrel has a gutter 37 and grooves 17, which surround the feed-bar. The rear end of the reed-bar fits closely within the end of the barrel, except for narrow crevices 16, Fig. 5, formed between it and the wall of the barrel by the lower margins of the nib, these crevices being in communication with the grooves 17. Excess ink can enter the recesses 26 owing to the flexing of the nib in writing, and may enter the diagonal slots 36, from which it can pass to the grooves 30 and the pocket 34. When the pen is inverted, the excess ink drain into the grooves 17 and through the crevices 16 to the reservoir.

Filed: 1958-02-10
Abstract: 849,340. Ball mills. PODMORE & SONS Ltd., W. Feb. 10, 1959 [Feb. 10, 1958], No. 4212/58. Class 59 A method of grinding consists in introducing air at the base of a grinding chamber whose lower portion at least is conical, the grinding chamber containing grinding media and the charge of the material being ground, subjecting the grinding chamber to a vibratory action which is communicated thereby to the grinding media, and the air flow being mixed with the charge, air loss from the charge at its surface being replaced by air entering at the base, so that the movement of the media and the fluidization of the charge by the air rising through it combine to facilitate the grinding action. Apparatus for carrying out the method comprises a chamber 10 containing grinding media and mounted on a platform 12 carried on springs 13 attached to a platform 14 vibrated by a unit 15. The chamber has one or more air inlets 16 and one or more flexible outlet ducts 20. Each duct 20 leads to a classifier 21 from which a valve-controlled pipe 22 returns oversize material to the chamber 10. The finer material from the classifier passes to a separator such as filter bags or, as shown, to a cyclone 27 where fine particles are collected in a bag 28. The air stream and dust passes from the cyclone to a dust collector 30 and dust deposited in a bag 31. The material to be ground is fed from a hopper 37 by means of a vibratory or other feeder 36 into an inlet shoot 35 having a perforated bottom plate. One or more slidably mounted tubes 40 opening to the atmosphere control the velocity of the air flows. Each air inlet may incorporate a pressureresponsive valve controlling an electrically-driven apparatus for feeding the material to be ground either along with the air or through a separate inlet

IPC: B61L1/16
Filed: 1932-02-13
Abstract: 379,983. Axle counting apparatus. VEREINIGTE EISENBAHN - SIGNALWERKE GES., Siemensstadt, Berlin. Feb. 13, 1932, No. 4357. Convention date, May 23, 1931. Addition to 372,436. [Class 105.] An axle-counting device comprises two stepby-step motors 41, 42 actuated by axles entering and leaving a section of track and interconnected through a differential gear 45 to drive a counting mechanism 48. The mechanism 48 closes a control contact 50, 51, 52 when in the zero position. A permanent magnet N, S polarizes the stator polepieces to hold the motor armatures in the position to which they were last moved. The motor armatures are stepped by the momentary energization of the stator poles by condenser current pulses when treadles 73, 74, 75 actuate the circuits shown in Fig. 3. In the normal state the condensers 76, 77 are charged but when a wheel reaches treadle 73 contact 73b opens and contact 73a closes so that winding 71 is energized from condenser 76 to step the armature ; winding 70 is also energized but in the direction to reduce the flux arising from the polarizing magnet and is therefore ineffective. When the treadle 74 is reached the contact 74a is closed to re-charge the condenser 76 directly. When treadle 75 is reached contact 75b opens and contact 75a closes so that winding 72 is energized from condenser 77 to step the armature again. When the wheel passes beyond the treadle 75 the condenser 77 is re-charged over the winding 70 which in this case is energized in the direction to increase'the flux and therefore to step the armature further to complete a half turn.
