Abstract: A B S T R A C T            "ELEMENT FOR IMPLANTATION IN BODY  TISSUE,PARTICULARLY BONE TISSUE"     In an element for implantation in body tissue, particularly bone tissue, consisting of a biologically flawless material with a micro-pitted surface, the pores in the surface have a diameter many times smaller than has been previously known in order to permit the occurrence of such a tight and extensive boundary zone around the implanted element that this achieves reinforced and inextricable anchoring in the tissue.          The pore diameter may be as little as about 10 nm and as large as a few multiples of the normal diameter of the cells in the tissue, preferably no larger than the cell diameter, i.e. about 1000 nm.   Optimal results are obtained with pore diameters equal to or smaller than about 300 nm and a finely pored rutile layer has been found to give a particularly strong and durable joint with the growing tissue.   Preferably at least one deposit of an agent facilitating and/or accelerating the growing-together process is arranged on or in the element.The element may be shaped with grooves, corrugations, channels etc. and be provided with an opening for tissue to grow through.   The element is extremely suitable as anchoring device for a prosthesis or partial prosthesis and may be made integral therewith.

Abstract: Abstract The disclosure is directed to an improved liner assembly for an ore grinding mill.  The liner assembly is of the segmented type,  comprising a first plurality of holder segments which are mounted directly to the shell of the mill,  and a second plurality of wear segments which are mounted to  the shell in overlying relation to the holder segments, which are thus virtually unexposed to the ore comminution process and wear very slowly. The wear segments are formed with a plurality of downwardly pro-jecting bosses which are received in similarly configured recesses  formed  within  the  holder  segments.   Mounting openings or bores are formed in the wear segments, ex-tending from the top grinding surface to the center of each boss to receive a mounting bolt that extends through both segments  and projects  externally of  the shell to receive a threaded lock nut.  These mounting openings are countersunk  so  that  the  heads  of  the  mounting bolts securing the wear segments are substantially recessed from the  grinding  surface.   The holder segments are secured directly to the shell by identical mounting bolts through mounting openings which are protectively covered by the wear segments to preclude exposure to the ore fragments during the comminution process.

Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus for welding studs to a work-piece are provided.  When studs are welded to workpieces using a drawn-aro, stud-welding technique, a coating of smut is sometimes deposited on the workpiece around the welded end of the stud.  This coating detracts from the appearance and if the workpiece is covered with coating material, such as paint, the smut must first be removed, requiring an extra operation. It has been found that the coating of smut will not be depos-ited, if, during the welding cycle, fluid is carefully deposited on the weld area around the end of the stud where the weld occurs. This fluid consists of a small volume of low pressure air and an anti-smut liquid.

Abstract: ABSTRACT OF THE DISCLOSURE A puffer type circuit interrupter in which finger-shaped arcing contacts are provided with a large cooling effect by gas which is provided to blow out the arc at the time of an interruption operation.  One of a pair of arcing contacts, which are connected to respective output terminals, is provided with a plurality of fingers designed to mate with the other of the arcing contacts.  The fingers are attached to a puffer cylinder which has formed in it passageways for directing gas compressed within the cylinder onto the fingers.  Inside the fingers is positioned a cylindrical gas guide which, together with a portion of the cylinder which may be a piston rod, directs the flow of air over the fingers in such a manner that the gas passes substantially completely over the fingers before reaching the arc. With this construction, the gas passing the fingers is not heated and hence the amount of metal vaporized from the fingers is quite small.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a method for making visible by photochemical means residual moisture distributions in photographic wet film layers subjected to a gas flow.  According to the invention, a film diffusely pre-exposed is immersed in an aqueous swelling agent solution which contains either (a) a reducing agent or (b) an alkali.          After being exposed to the air stream, the invisible residual moisture profile is immersed in an alcoholic solution of either (a) an alkali or (b) a reducing agent.  The half-tone image produced serves for determining stationary local boundary layer thickness distributions, wall shearing stresses, material transfer coefficients and heat transfer coefficients.

Abstract: ABSTRACT OF THE DISCLOSURE   A form for supporting from below a layer of concrete during pouring and hardening has several square or rectangular panels having neighboring marginal portions with downwardly extending reinforcing skirts which are separably connec-ted to each other by bolts. The panels rest on props which must be removed prior to separation of the panels from each other in order to dismantle the form in the space below the hardened concrete layer.  To this end, the props for one of the panels are removed and a dismantling device is separably coupled to a panel which is adjacent to the one panel.  The dismantling device has a socket below the skirt of the one panel and the one panel is thereupon detached from the panel which carries the dismantling device so that the skirt of the one panel descends into the socket.  The one panel is then pivoted with reference to the socketed part of the dismantling device so that its upper side moves away from the under-side of the concrete layer.  The dismantling device is thereupon transferred to another panel adjacent to a panel which is about to be detached.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention discloses a paper-machine multiple-cylin-der dryer having a means by which air is transported to the dryer.          In conjunction with the means, members are provided by which the outblowing of air is accomplished.  It is possible with this means to direct dry air into the vicinity of the web at those points where the evaporation of water from the web is strongest, and thereby to reduce the humidity in such a region, whereby the evaporation of water from the web is promoted.  Points of this kind are the initial parts of the cylinder intervals after a cylinder in contact with the web.  The air supply means are so placed and their blow-out elements so disposed and directed that the the air blown out from the means is aimed into the cleft of clefts defined by the surface of the drying cylinder and the paper web.  With this method an over-pressure is established in the cleft. The supply means is used above all for so-called single-fabric conduction in the pockets on the side of the web to urge the web against the fabric.  The means is preferably disposed on the doctor beam or in association therewith.

Abstract: ABSTRACT A gun mount having a gun cover or shield contains a gun which may be directed in both azimuth and elevation.  An ammunition storage space is disposed below the gun mount. Ammunition components are combined in the storage space to provide an ammunition round with the long axis of the round substantially vertical.  The barrel of the gun is elevated to the 90° or vertical position and when the breech block is opened the vertically disposed ammunition round is hoisted directly into the open breech.  The round is latched in the breech while the hoisting mechanism is withdrawn and the breech is closed.  Thereafter the gun may be depressed to a desired firing elevation and the round fired.  The gun is then positioned at a predetermined intermediate elevation angle so that the gun breech is adjacent to a door in the gun cover which is controlled between open and closed positions. The breech is opened, the door is opened and the empty propellant case from the fired round is ejected through the open door.  The gun is then repositioned to the vertical position to receive another round in the breech and the process is repeated.  Conventional length ballistic projectiles and ultra-long guided projectiles may be handled by the disclosed loading system and the loading may be accomplished at any angle or azimuth or train.
