Title: Method of producing a guide vane ring for a return flow passage in axial fans
Inventor: KARLSSON SUNE
IPC: F04D29/54
Filed: 1984-03-09
Granted: 1986-11-06
Abstract: A guide vane ring for a return flow passage in axial fans comprises a ring (3) intended for placing in the return flow passage (4) coaxial with the impeller (6). A plurality of guide vanes (7) are formed integral with the ring and distributed round its exterior circumference. in a method of producing such a ring integral with its vanes, separate longitudinal slits are formed in a line one afterthe other in a metal strip. A cut is made transverse the strip between one end of each slit and one long edge of the strip. Portions of the band thus cut free are bent out from its plane and formed to a desired configuration, whereafter the formed band portions are bent such that the transverse cut lines will extend substantially at right-angles to the unformed flat band portion. This flat band portion is cut to desired length, formed and joined together into a circular ring with the portions formed to desired configuration forming exterior, substantially axially disposed guide vanes.

Title: Drilling tool with replaceable cutting bit
Inventor: FAUSTKA HELMUT
IPC: B23B51/00
Filed: 1984-02-21
Granted: 1988-01-07
Abstract: Drilling tool comprising a tool shaft with at least one flute and an interchangeable cutting element. The cutting element is comprised of one or two cutting flute plates having each a main cutting edge. On the narrow side of the plate, facing the bit, there is provided a fixing trunnion concentrically with respect to the bit axis and having two mounting surfaces. The tool shaft has at its point in the wall of the flutes a flat hollow for the cutting plates and, at the middle, in a concentric position with respect to the bit axis, a housing for the fixing trunnion with lateral surfaces for the assembly. The cutting element is inserted from the top, rotated at about 45<o> towards the rear wall of the hollow, into the shaft point and secured by a rotation in the drilling rotation direction. During the drilling, it is supported against the cutting efforts by the back wall of the hollow and its edge facing the shaft. The fixing trunnion maintains the cutting elements in a concentric position. Thereby the cutting element is biased by the cutting efforts into its seat and is secured therein without requiring additional securing devices such as screws. The configuration of the fixing trunnion may be conical, cylindrical or as a dovetail.

Abstract: A screen printing apparatus is provided for transferring sheet materials from a supply area to a printing table. The apparatus has a pair of grippers which are guided jointly over the printing table in a timed manner in order to grip a blank sheet at a feeding table and pull it over the printing table. The two grippers are separately guided above the printing table in such a way that their movements take place in opposite directions to one another and that one of the gripper fails passes over the other one in the area of the center of the printing table. This design has the advantage that during the transport by a first gripper of a sheet to be printed on the printing table, a second gripper rail already returns to its starting position. Therefore, when the printed sheet is removed from the printing table, a new sheet can be placed thereupon immediately. Idle times for the conveying of the sheets to be printed are eliminated with the use of only two grippers.

Abstract: Device for simulating multipath interference in order that the correction stages of a radio receiver can be tested. The device includes parallel paths (54,55), simulating the multipath environment, and a pilot tone generator (60) for introducing pilot tone into the paths. A feed-back loop continuously adjusts the phase and amplitude of a segment in one of the paths so as to cancel pilot tone from the output whereby the loop maintains the adjustment need for maximum attenuation at the frequency of the pilot tone. The device further also comprises; means (90, 91, 92, 93, 94, 95, 96) for selectively re-introducing a signal corresponding to that in one of said parallel paths (54), (55, 58), so as to reduce the severity of maximum attenuation of the notch.

The screens may be collapsed over the hot material thereby completely surrounding and insulating the material from loss of heat. A displaceable chamber installation is also described for limiting heat loss when holding and transferring hot material between processing stages.

Abstract: A process for making a formed flexible plastic foam product containing a fibrous web insert. In the process, a flexible ethylene containing sheet material is rapidly heated and die formed to provide multiple parallel shells integrally attached to the sheet. A fibrous web material having an elongated corrugated shape is filled with an absorbent powder, and is die cut to individual desired shapes which are inserted into the shells. A thin fibrous facing sheet material is placed over the powder-filled web and formed shell and the facing sheet is heat sealed onto the foam shell perimeter, after which the formed and filled foam shells are die cut from the plastic foam strip to produce the individual formed products. The process advantageously provides increased production rates at 10-30 cycles/minute for the formed products.
