Title: Tool turret for machine tools, in particular lathes
Inventor: FORST HEINZ
IPC: B23B29/32
Filed: 1982-01-23
Abstract: A tool turret for machine tools, in particular lathes, has a tool disc which is rotatably mounted about the turret axis in a housing, can be indexed step-by-step by means of an allocated stepping drive and has a number of location bores which are arranged in a uniformly distributed manner in accordance with the tool stations and are axially parallel to the turret axis and in which in each case tool holders provided with a location shank are accommodated in a preferably interchangeable manner. In order to also optionally permit the use of rotating tools and in the process to make possible the use of commercially available turret heads without interfering with their internal construction, a gear which can be driven by a dedicated drive source and is coaxial with the turret axis is rotatably mounted on the tool disc, the tooth system of which gear lies in the area of the location bores, in which arrangement tool holders with rotating tools each have a drive shaft which is rotatably mounted in the location shank and carries at the end a drive pinion which meshes with the gear when the location shank is pushed from the outside into the respective location bore.

Title: Method for compensating for differential errors in analog/digital measuring systems which operate in accordance with the method of progressive approximation
Inventor: BERLIN HARALD DR
IPC: H03M1/00
Filed: 1982-07-14
Abstract: This object is achieved by the following rule for allocating the digitised measurement values: provided that the binary combination between two adjacent digital measurement values m and m + 1 changes by more than one binary position, the adjacent binary numbers thus distinguished are jointly allocated to a new value. In principle, this method makes it possible to solve problems requiring high differential linearity of the measuring system (e.g. pulse amplitude analysis of static events) in a better and simpler manner.

Patent DE-3245629-A1 (DE)
Title: Fuse element with a thick-film resistor arrangement
Inventor: GEHRKE-SCHREIBER LUTZ DIPL PHY
IPC: H05K3/28
Filed: 1982-12-09
Abstract: A fuse element consists of a thick-film resistor arrangement on a wafer 1. In order to achieve reliable response in the event of an overload in this case, a homogeneous thick-film resistor 4 is deposited between two strip-shaped electrodes 2, 3 running at a distance from one another. In addition, a thin-wire 5 runs from one electrode 2 at right angles over the thick-film resistor 4 and the second electrode 3 to a connecting electrode 6. The thick-film resistor 4 and the wire 5 are covered with an insulating layer 8, or are embedded therein. In the event of a medium overload, the thick-film resistor partially overheats the wafer 1 located underneath it, which wafer fails as a result of thermomechanical stresses. On the other hand, if high voltages are applied, a spark breakdown occurs over the thick-film resistor 4 between the electrodes 2, 3, by means of which the insulating layer 8 is blown off or broken up. In consequence, an interruption occurs in the region of the wire 5. <IMAGE>

Patent DE-3315214-A1 (DE)
Inventor: BURKHARDT HORST DR
IPC: G01B21/00
Filed: 1983-04-27
Abstract: A length measuring instrument includes a flexible measuring band which slides in a groove defined by a scale carrier body. The measuring band is fixed at one end to the carrier body. The second, free end of the measuring band is fastened in an oscillator which excites this free end into high frequency, low amplitude vibrations. These vibrations act virtually to eliminate harmful friction between the measuring band and the scale carrier body, and to reduce fouling of the measuring band markedly.

Title: Function selector switch for powered percussion drills
Inventor: TASHIMO FUMIO
IPC: B25D16/00
Filed: 1983-08-26
Abstract: A powered percussion drill is described which can alternatively be operated in a drilling mode, in which a drill-chuck drive spindle is rotated without axial movement, and in a percussion-drilling mode in which the drive spindle is additionally moved back and forth. The drilling mode is set by a change-over plate, mounted so as to be displaceable into a holder in the drilling machine housing, being pressed in a direction in which teeth of a gear connected to the drive spindle are disengaged from the teeth on the holder. The percussion-drilling mode is set by the change-over plate being pressed in the other direction in order to bring the teeth of the gear into engagement with the teeth on the holder. When the drill insert connected to the rotating drive spindle is pressed against a workpiece in this operating mode, the alternating engaging and disengaging of the teeth cause the drive spindle to perform an axial reciprocating movement.

Title: Method for the cold forming of virtually symmetrical metal workpieces
Inventor: WITTKE MANFRED DIPL ING
IPC: B21K1/76
Filed: 1983-12-14
Abstract: A method for the cold forming of virtually symmetrical metal workpieces. The technical problem of the invention is to provide a method which makes possible cold forming of such workpieces by simple procedures and with high dimensional accuracy. A bar-shaped blank with a fine-grained structure and a volume essentially equal to that of the workpiece is converted by reduction in one or more stages into an intermediate with a reduced shank and an unreduced head. The intermediate is upset at one or both ends. The intermediate is then forged in a closed die to give the finished workpiece. <IMAGE>

Title: Device for winding up the hoisting rope of a crane
Inventor: TRAPP HELMUT
IPC: B66D1/38
Filed: 1983-12-17
Abstract: In a device for winding up a loaded rope onto a rope drum, the rope being run via a lead-in pulley and a guide pulley to the rope drum, the rope (10) is run between lead-in pulley (11) and rope drum (13) via a pair of guide pulleys (21, 22) arranged on a pulley carrier (20), in which arrangement a) the pulley carrier (20) is pivotably mounted with one of its ends in the area of the lead-in pulley (11) and at a distance above the latter and has the first guide pulley (21) at this end, and b) the pulley carrier (20), as viewed from the lead-in pulley (11), is supported behind and above the rope drum (13) on a running rail (27) and has the second guide pulley (22) above the rope drum (13), as a result of which there is an approximately rectangular rope run between lead-in pulley (11), guide-pulley pair (21, 22) and rope drum (13). Thus a device of the type as defined in the preamble is specified which permits the use of a wide and at the same time thin rope drum and which as a unit permits a compact, that is to say squat, load-rope guide overall. Thus, with regard to use in a tower crane, the intention is ultimately also to be able to construct a compact, that is to say space-saving, central machine unit for accommodating the hoisting-rope guide. <IMAGE>
