Abstract: A dual string packer (not shown) is milled by a mill having an annular milling shoe (16) for milling the periphery of the packer and freeing it from the well bore. An axial milling head (24) mills a central hole in the top of the packer before the annular shoe (16) reaches the locking segment of the packer. A grapple (50) above the milling head engages the walls of the axial hole drilled in the packer to support the remains of the packer in the well. The grapple (50) includes a release ring (44) that can be broken in tension to release the packer mill from a stuck packer if need be. The grapple comprises a gripper sleeve (50) with longitudinally extending fingers (54) and a camming sleeve (40) for camming the fingers (54) outwardly. An expandable ring (60) inside the camming sleeve provides means for withdrawing the camming sleeve (40) from the gripper sleeve (50) if it should stick.

Abstract: A deadplate arrangement for a horizontal single filer conveyor is provided for maintaining an equilateral contiguous triangular configuration of flexible walled containers (10) as they move across the deadplate (12). The containers (10) are held in this alignment by side rails (18,18ʹ,20,20ʹ) which engage the containers at their rigid bottom-most portion. The deadplate has a downstream edge (22ʹ) whose most downstream portion is truncated (46) so that the downstream container (10A) is subjected to the vacuum of the transfer belt (34) before the other containers in the diagonal row (10B,10C). In addition, adjacent the downstream edge of the deadplate (12) are slots (24) which correspond in width and positioning to the openings (32) in the transfer belt for the outside container and a narrower slot (48) is provided over one of the rows of openings in the transfer belt for the center container (10B). This arrangement ensures that the containers (10) are not prematurely drafted onto the transfer belt but that the outside container moves ahead of the other containers as it moves onto the transfer belt so that the deflector will bring all of the containers into single file alignment by the time they reach downstream single file rails (38,38ʹ).

Abstract: An electric motor-actuated load clamp (12) for automatically-guided vehicles (10) has clamp arms (16) which are selectively opened and closed by a plurality of rotary electric motors (28) connected to the clamp arms by ball screws (18, 20, 22). Clamping force is accurately controlled by regulation of current to the electric motors (28), any of a number of different predetermined clamping forces being selectively obtainable. During clamping of a load, the electric motors (28) are energized only a small fraction of the time according to a time-sequenced alamping and reclamping procedure, clamping force being otherwise maintained by a one-way brake (42). Further control features ensure against inaccuracy and overclamping due to current inrush, and against malfunctions which could cause safety hazards.

Abstract: Disclosed is an electronic typewriter with a word correction function substantially consists of a print data memory, a correction word memory, correction determination means, selection means and correction control means. If a correction word is too long to be printed in place of an erased wrong word, the selection means is driven to select a least number of neighboring words to be erased. The correction control means controls the pitch of the correction word and its adjacent spaces before and after the word. Since the correction range can be extended to the right and left margins, a relatively long word can be automatically substituted for the erased wrong word.

Abstract: In order to produce hard materials at short reaction times (about 1 - 10 ms) particularly on the flight paths of the spray particles in an inexpensive manner during arc-spraying, exothermically reacting pulverulent starting materials with hard materials and/or metallic and non-metallic elements and/or prealloys in powder form are first treated with organic or inorganic binders and composite powders are prepared from these by spray-drying or agglomeration and then used for filling hollow wires.
 Owing to the reaction path which has been shortened thereby as compared with a loose powder mixture, and the simultaneous release of energy due to exothermic reactions taking place, the proportion of hard material in the sprayed layers is significantly increased.
