Title: Improvements in or relating to grinding mills
IPC: B02C19/10
Filed: 1947-11-27
Abstract: 629,916. Grinding-mills. HARDTMUTH (GREAT BRITAIN), Ltd.. L. & C., and ZUCKERT, R. Nov. 27, 1947, No. 31452. [Class 59] A mill, particularly for grinding a mixture of graphite and water, comprises a cylindrical casing a, having an inner peripheral wall with an arcuate insert q of hard ceramic material, and a cylindrical rotor m mounted on an eccentric-driving shaft n and carrying grinding blocks s which are slidable radially under the action of centrifugal force. The casing is provided with inlet and outlet pipes c and d communicating with chambers e and f which are separated from the grinding chamber by a plate g formed with an inlet passage j and outlet passage k, the latter extending for 20 degrees up to the position where the peripheries of the rotor and casing are tangential to one another, and the former for about 120 degrees as shown in Fig. 3. The operative faces of the grinding blocks have the same curvature as the periphery of the casing, and their leading ends t are of reduced radius as shown in Fig. 2. The eccentric mounting of the rotor causes it to act as a pump so that material is drawn in through the passage j and expelled through the passage k. If desired, this pumping action may be supplemented by positive and negative pressure means operated so that impulses occur when the spaces between adjacent blocks are opposite the entrance and exit passages. The grinding blocks may be pressed outwardly by springs. The ground material may pass to a storage vessel in which it is agitated, and then returned to the mill for regrinding. Alternatively, a number of mills may be arranged in series. The mill casing and/or storage vessel may be water-cooled.

Abstract: 454,817. Insulators. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Nov. 15, 1935, No. 31698. Convention date, Nov. 16, 1934. [Class 36] [See also Group XL] An arrangement for the insulated attachment of metal parts in vacuum discharge apparatus, such as gas- or vapour - filled rectifiers, comprises an insulator lying wholly between and secured at each end to the metal parts and surrounded by one or more screens of conductive or nonconductive material, each screen being arranged closely adjacent to the insulator, but only in contact therewith at one end, to which it is rigidly secured. The screens protect the insulator from metal particles deposited by the discharge, and, when conducting o r rendered conductive by such particles, determine the field at the surface of the insulator. In the form shown in Fig. 1, metal parts 5, 6 are bolted to an insulator 4 and the screen 1 has a flange which is clamped between the shoulder 9 and the metal part 5. In a modification, Fig. 2, two screens 11, 12 are connected to opposite ends of the insulator 10 by pressing them into grooves 13, 14. The screens are spaced sufficiently closely to avoid a discharge between them. Connection to the metal parts is by bolts 15, 16 held loosely in recesses in the insulator by extensions of the screens. The size of the bolts is chosen so that they just fill the recesses at the highest working temperature. The bolts may be displaced from the axis of the insulator to permit overlapping. In a further modification, Fig. 4, the corrugated insulator 24 is secured to end caps 27, 28 by transverse bolts 29, 30. The screen 26 is held within the cap 27. The caps have screw-threaded extensions for securing to the metal parts.

Title: Improvements in or relating to sheet detectors
IPC: B65H7/08
Filed: 1945-11-26
Abstract: 604,486. Feeding sheets and webs. STEVENS, A. H. (Harris-Seybold-Potter Co.). Nov. 26, 1945, No. 31810. [Classes, 100(i) and 100(ii)] A sheet detector, which is used to control the operation of a printing or other machine in the case of improper feed, or which can be applied to effect transverse guiding of a web, is constructed so that detector is held by magnetic action against movement by the sheet or web. In Figs. 1 and 4, a detector 16 of magnetic material is pivoted to an oscillating arm 19 and as sheets are moved to engage front stops 12 they engage the lower end 15 of the detector which is lowered into a slot 14 in the feed board 10. The detector is thus moved to the dotted line position, Fig. 4, against the action of a horseshoe magnet 21 which is adjustably mounted in the arm 19, and is moved out of engagement with a projection 29 on a trip arm 27. If no sheet is fed the end 16 engages the projection 29 and in so doing causes the machine to be tripped. The magnet 21 is preferably arranged so that the arm 15 engages only one of its edges; and the magnet is adjustable in position and is controlled by a stop 26 which prevents it from swinging over. As shown in Fig. 6 the detector 16 is arranged adjacent to rollers 42, 43 which register a sheet 44 against side gauges after it is registered by front stops 45. An adjustably mounted magnet 52 controls the motion of the detector 16 which as in the prior case is moved out of the way of a projection 29 when engaged by the side edge of a sheet. In a further modification for adjusting the transverse register of a web a pair of detectors are pivotally mounted so as to engage the side edges of a moving web, and if the web deviates to either side a relay is operated to throw in a motor for restoring the position of the supply feed roll. The detector is held in normal position by magnetic action, and the relay is operated by a circuit which normally passes through the detector and through the magnet.
