IPC: E21B19/18
Filed: 1973-02-08
Abstract: 1357715 Unscrewing drill bits from drill rods LINDEN-ALIMAK AB 8 Feb 1973 [8 Feb 1972] 6275/73 Heading B3N A device for exchanging a drill bit 8 on a drill rod 3 comprises a magazine 4 for delivering the bits and means for effecting relative rotation between the rod and bit for screwing the bits on and off the rod. The magazine 4, Fig. 1, may consist of a rotatable cartridge 5 having a number of rubber holders 7 for storing and holding the bits and a device 21 for stepping round the cartridge about an axis 6. The drill frame 1 may be provided with an arm 11 pivotable about an axis 10 by a piston unit 13 from the position shown by dash-dotted lines to the operative position where a wrench member 14 contained in a casing 15 can be applied to the drill bit. When a drill bit is to be exchanged, the drill rod 3 is retracted to the left until the old bit 8 enters the empty rubber holder 7. The arm 11 is then swung up so that the wrench member 14 engages the bit by its projections 20, Fig. 2. The drill rod 3 is then rotated so that the bit is screwed off and retained within the casing 15, a wrenching action being brought about by projections 18 on the wrench member 14 striking stop members 17 on the casing. The drill rod 3 is then retracted clear of the rubber holder 7 and the old bit pushed back into the holder by a piston unit 16. After the arm 11 has been swung out of the way, the cartridge 5 is stepped round to present a new bit 8 to the drill rod which is rotated and fed forwardly into the bit as it is held by its rubber holder 7. Alternatively, the drill bit may be arranged to rotate instead of the drill rod for screwing purposes. Instead of being mounted on the drill frame 1, the device may be mounted on the rack wall. In another embodiment, Figs. 3 to 5 (not shown), the magazine (30) may consist of a casing (37) having an aperture (36) for the drill rod (3), a wrench member (40) and a piston unit (46), the casing being pivotable about an axis (48) to bring the aperture opposite the drill rod. The magazine may contain a cartridge in the form of a chain which runs over sprocket wheels (34, 35), the drill bits being held by arms (31) secured to the links of the chain; the arms automatically release the bit adjacent the lowermost sprocket. When a drill bit is to be exchanged, the drill rod (3) with the old bit is pushed through the aperture until the bit is engaged with the wrench member (40). The drill rod is then rotated to screw off the old bit and is retracted from the magazine. The hold bit is pushed by the piston unit (46) into the empty space between a pair of arms (31) on the chain before the chain is stepped round by a device (47) to bring a new drill bit into place. The drill rod is advanced again through the aperture to push the new bit into engagement with the wrench and the drill rod then rotated to screw the bit on. The drill rod with bit is then withdrawn and the magazine pivoted clear.

Title: Rotary Pumps.
IPC: A61M1/00
Filed: 1968-02-09
Abstract: 1,166,225. Centrifugal pumps. AMERICAN OPTICAL CORP. Feb. 9, 1968 [March 22, 1967], No. 6642/68. Heading F1C. A rotary pump comprises a housing divided by an annular partition into upper and lower chambers, the partition being integral with or in circumferential contact with the inner surface of the lower chamber so as to provide an overflow passage having a smaller radius than the lower chamber, an intake impeller in the lower chamber and a discharge impeller in the upper chamber, at least one intake pipe communicating with the lower chamber and projecting into it, and a discharge port communicating with the upper chamber. The housing comprises sections 22, 23, 24, Fig. 3, and a cover plate 19, held together by tie rods (not shown). The electric driving motor (not shown) is bolted to the coverplate 19 with its shaft 33 connected to a stub shaft 32. Impellers 30, 31 are clamped against a shoulder 32' on the stub shaft 32 by means of a clamping disc 34 and screws 36. Impeller 30 comprises a disc 49 formed with holes 50 and carrying depending vanes 47. Impeller 31 comprises discs 53, 54, 55 each formed with holes 56, Figs. 3 and 5, and notched at 58 to form vanes 59. Intake pipes 38 project into the housing between the discs 53, 54, 55, and are connected to separate sources of liquid. Any unused intake pipes 38 may be sealed off or allowed to remain open and suck air into the pump. The pump can be initially primed through the discharge connection 64. The impeller 31 rotates the liquid present in the base of the pump to form a vortex. The ends of the intake pipes 38 are below the free inner surface of the vortex, and the high velocity of the liquid passing over them creates a partial vacuum to draw liquid from any vessel to which any intake pipe is connected. The liquid drawn into the pump rises above an overflow partition 44 and is discharged through the discharge connection 64 by the impeller 30. Air drawn into the pump leaves through impeller holes 56 and 50, space 66 and overflow port 65. If there is only intermittent liquid intake, the stepped lower surface of the partition 44 retains sufficient to keep the pump primed, this liquid returning to the lower part of the pump casing through holes 57 in the disc 53. If the discharge connection 64 is blocked, any overflow from the pump housing can leave through the overflow port 65. A normally closed sludge drain 60 permits the pump housing to be cleaned and drained. In a simplified embodiment, Figs. 10-12 (not shown), the lower impeller (31a) comprises a single disc carrying dependent vanes (69) each formed with a slot (70) to clean the intake pipes (38).
