Title: Apparatus for sludge collection and sludge removal in longitudinal settling tanks
Inventor: KNAPP CHARLES ALBERT
IPC: B01D21/04
Filed: 1955-10-17
Abstract: 784,602. Gravity separation of solids from liquids. DORR-OLIVER, Inc. Oct. 17, 1955, No. 29504/55. Class 46. [Also in Group XXXVII] In a settling tank having at opposite ends an inlet and an outlet for liquor, at the bottom thereof an outlet for sludge &C and thereon a driving mechanism for reciprocating rakes over the full length of the bottom with automatic reversal at the ends of the tank, a control system is provided to limit the reciprocation to the immediate vicinity of the sludge outlet. An electric motor M reciprocates a rake carrier 14 along a tank 10, limit switches 22, 23 at the end of the tank effecting reversal of the motor through a relay 24 and reversing switch 25 (see Group XXXVII). Brackets 19 on the carrier 14 support rakes 20, 21 through pivoted arms 17, 18 and the rakes have blades which displace the sludge laterally as well as longitudinally. The limit switch 23 may be short-circuited by a manual switch 60 to reverse the carrier when the rakes have just cleared the sludge outlet 13, several of these short reciprocations being made if desired before the next full, automatically controlled stroke. A timing clock may actuate the switch 60 periodically. U.S.A. Specification 2,670,080 is referred to.

Abstract: 300,006. Willcox & Gibbs Sewing Machine Co., Ltd., and Berrisford, R. Nov. 4, 1927. Work - supports, - The needle-throat plate C of a vibrating needle machine moves synchronously with the needle bar and has its upper surface below that of the work-support to avoid any tendency of the work to follow its movements. The work support A is secured to a block B by a screw and has the usual slot a<1> for the fourmotion feed dog and a slot a<2> for the needle which enters the hole c in the throat-plate C. The throat-plate slides in a groove in the block B and is reciprocated by a link D suitably connected to the driving mechanism. The operative part c<2> of the throat plate is reduced in thickness and projects somewhat above the main portion, but is below the level of the upper surface of the work support surface A.

Flat extended surfaces, surfacing and polishing; tools.-In a machine for grinding, smoothing and polishing plates of glass, marble, &c., the plate is traversed or reciprocated beneath grinding &c. tools which are moved in a direction at right angles to that of the movement of the glass &c. On a frame 1 are supported vertically adjustable counterbalanced parts 3, to which are pivotally connected frames 8 carrying a rail 11, on which are mounted, by means of wheels, 24, the grinding &c. elements 14. Each element consists of a frame 22 supporting rollers 21 guided by rails 12 and carrying also the grinding &c. tools 13<1>, Fig. 4a, or polishing tools 13. The tools have interengaging parts 16, 17 linked together to form continuous chain, so that when driven by motors the two runs of the chain move across the glass in opposite directions. The glass &c. is mounted on a table or platform 31 secured to a frame 30 by spring pressed bolts 32, Fig. 7, and a series of frames coupled together by parts 38 and bolts 40 are moved beneath the tools on rails 35, guide rails 37 and rollers 36 also being provided; the frames are moved by engagement of an adjustable fork 44, Fig. 8, with a moving chain 43, tables carrying glass which has been ground and smoothed being removed, and fresh tables added.

Filed: 1967-06-28
Abstract: 1,137,611. Selecting records. HOUSTON FEARLESS CORP. 28 June, 1967 [7 July, 1966], No. 29830/67. Heading G4M. A common storage drum 21 contains a plurality of edge-notched cards which are addressable by selectors 22 at any one of stations A-D, electrical interlocks preventing selection operations by more than one station at a time. Assuming an operator at one of stations A-D wishes to return a card to drum 21 and select a new card, the address of the new card is entered by a set of switches and a start button is operated. A motor M2 is energized to rotate cams which cause a pair of wedges to execute movements in a rectangular path so as to separate the cards in drum 21 adjacent the card manipulator 28 at the operative station. A further cam then actuates switches to energize a motor M3 to drive the card manipulator 28 inwards so as to insert the old card into drum 21. When manipulator 28 has completed its inward movement, a limit switch de-energizes M3 and causes M2 to be energized again for a short period to withdraw the wedges from the cards. The drum motor M1 is then energized to rotate drum 21, and the selector 22, as set up by the previously actuated switches, allows the desired new card to be drawn partially out of the drum by a magnet 23, this condition being sensed by a reed switch 26 and causing M1 to be de-energized so that drum 21 coasts to a stop with the new selected card engaging the manipulating member 28. A guide bar 29 completes the return of a card to drum 21 when it starts to rotate. Motor M2 is then energized to drive the wedges along the rectangu. lar path to separate the cards in drum 21 from the selected card, and M3 is then energized to move the card manipulator 28 to withdraw the selected card. Finally, M2 is energized to withdraw the wedges from the cards, and, the selection operation completed, the other stations are released for selection operations by other operators. The station interlock arrangement is such that when any station is performing a selection (or card return) operation, no other station is operative, though the operation of their respective start buttons is stored to initiate selection when the operative station has completed its operation. When more than one station attempts to address the store at a given time, the stations become operative serially on a priority basis.

The drive shafts may be intergeared by a chain or by a gear train or by an internally or externally toothed spur gear 2. The roll shafts are mounted in housings 8 journalled on the shafts 4 the housings being provided with one or more slots 15 for the reception of locking bolts which engage with T-slots in the machine framing. A bolt 13 at the roll end of the housing is locked after the roll has been roughly set, fine adjustment of the roll being effected by movement of the housing by nuts 22, Fig. 5, on a gudgeon 19 carried by the bolt 13.
