Patent DE-3720630-A1 (DE)
Inventor: BAUER WALTER
IPC: B23B29/034
Filed: 1987-06-23
Abstract: A drill for performing a roughing cut in a workpiece as the drill is advanced, and performing a finishing cut as the drill is retracted. A blade carrier is mounted eccentrically on the drill to be movable between first and second positions. In the first position, the blade is located for a roughing cut. In the second position, the blade is shifted radially for a finishing cut. A spring biases the carrier toward the second position and yields when the carrier moves to the first position. The spring bias is too weak to overcome reaction forces acting on the blade during a roughing cut, wherein the roughing cut reaction forces cause the carrier to be shifted to the first (roughing cut) position. The spring bias is strong enough to overcome the weaker reaction forces occurring during a finishing cut, so that the carrier is automatically shifted to the second (finishing cut) position when the drill is withdrawn through the workpiece. Thus, the blade is automatically shifted from the roughing-cut position to the finishing-cut in response to the initiation of a movement of the tool in a direction of withdrawal through the roughly cut hole.

Title: Method for checking operational functions of a computer-controlled communication switching system
Inventor: BACHHUBER GERHARD
IPC: H04M3/32
Filed: 1987-12-23
Abstract: A computer-controlled communication switching system (VST) is connected to a traffic simulation device (VSE) and to a personal computer (PC) which, in turn, is connected to the device (VSE). Setting instructions (E1, E2) which place the operational state of the system (VST) into a defined state are supplied to the system (VST) from the personal computer (PC). Triggered by checking instructions (Ü1, Ü2) triggered by the personal computer (PC), the device (VSE) selectively checks those characteristics of the system (VST) which are first established by the setting instructions (E1, E2). After the checking instructions (Ü1, Ü2) have been executed, the device (VSE) forms information items (I1, I2) describing the actual state of the system (VST) and supplies these to the personal computer (PC). The latter checks the actual-state information items (I1, I2) against predetermined nominal-state information items (S1, S2). <IMAGE>

Patent DE-3812859-A1 (DE)
Inventor: BERWEIN HANS-JUERGEN DIPL ING
IPC: B66C3/04
Filed: 1988-04-18
Abstract: In the case of a conventional grab, e.g. of a crane, there is the risk, when working in a scrap bunker, of this grab striking the wall of the scrap bunker and damaging the concrete in the process. In order to provide a remedy here, it is proposed according to the invention that the grab (8) be provided on the outside with elastic cushions (12, 14) or flexible linings (30) at the points where it could strike the wall. In this way, the impact energy can be absorbed. The hitherto conventional expensive lining with a wooden casing is thus dispensed with. The cushions (12, 14) and linings (30) can easily be exchanged when required without the operation of the scrap-handling plant having to be interrupted. <IMAGE>

Patent DE-3825361-A1 (DE)
Title: Method and installation for regenerating mixtures of used foundry sand
Inventor: JACOB HERMANN
IPC: B22C5/18
Filed: 1988-07-26
Abstract: To regenerate mixtures of used foundry sand from mixture components which can only be regenerated thermally and mixture components which can be regenerated mechanically and/or pneumatically, the mixture is, in a first regeneration step, regenerated mechanically and/or pneumatically, then, in a second regeneration step, regenerated thermally and, following this, in a third regeneration step, regenerated mechanically and/or pneumatically again. For thermal regeneration, a thermal treatment comprising the heating or cooling of the sand mixture is carried out in such a way that the coatings of the sand grains are heated or cooled more rapidly than the sand grains themselves and that, as a result of the different expansion behaviour of the coatings, on the one hand, and the sand grains, on the other, thermal stresses are created in the former, resulting in the splitting open of the coatings.

Abstract: The invention relates to a process for heat recovery during sludge treatment, especially in the hygienisation of sewage sludge, in which raw sludge is maintained at a temperature of about 60 to about 62 DEG C in a reactor 1. It is proposed, for preheating of the raw sludge and for cooling of the hygienised sludge drawn off from the reactor 1, that a heat exchanger 5, which has at least two chambers 8, 9, is charged in alternate periods with raw sludge and hygienised sludge. In the first period, the raw sludge is introduced into the first chamber 8 of the heat exchanger 5 and subjected to heat exchange with the precooled hygienised sludge present in the second chamber 9. Subsequently the hygienised sludge is drawn off and discharged, for example, into the digestion tank. In the second period, the hygienised sludge, which is at about 60 to about 62 DEG C from the reactor 1 is introduced into the second chamber 9 and subjected to heat exchange with the raw sludge preheated in the first period. Subsequently the raw sludge is discharged into the reactor 1. The first period then starts again.

Title: Frequency-selective optical data recording and data reproduction apparatus
Inventor: TAKEUCHI KOICHI
IPC: G11B7/125
Filed: 1988-08-16
Abstract: The frequency-selective optical data recording and data reproduction apparatus generates a light beam which is directed at a recording medium (disk 5) and the wavelength of which sequentially assumes different values, the information bits being recorded or read at different wavelengths. In dependence on the wavelength, the light emitted from a plurality of light sources (LD1-LD4), the wavelengths of which belong to different wavelength bands, is projected along a predetermined light path and concentrated by means of a light concentration apparatus (107) to form a light spot on the recording medium for the purpose of recording and reproducing data. The light reflected by the recording medium is distributed by means of a distribution and concentration apparatus (108) in dependence on its wavelength simultaneously to various points, at which it is sensed by detectors. The light coming from the light sources (LD1-LD4) is polarised in a polarisation apparatus (105, 106) and concentrated on the recording medium. In the polarisation apparatus (105, 106), the light reflected by the recording medium is also polarised. <IMAGE>

Title: Drive mechanism
Inventor: REICHL ERWIN DIPL ING
IPC: H01H3/48
Filed: 1989-03-03
Abstract: The invention relates to a drive mechanism for operating a vacuum switch having a push-rod drive, in the case of which the coupling rod (6) is moved by means of its rotating joints (11, 12) in a longitudinal guide (1) and a transverse guide (2). In this case, the transverse guide (2) has a first section (3) which runs in the form of a circular arc and in which the second rotating joint (12) is at any point when the vacuum switch (20) is in the switched-on position, without the spring (13) which produces the contact force in this case exerting reaction forces via the drive rod (8) on the energy store. The transverse guide (2) is terminated by a third section (5) which likewise has a course in the form of a circular arc. The design according to the invention of the transverse guide (2) of the push-rod drive allows the production of a uniform switch stroke (h) independently of the manufacturing tolerances of the switch drive and of its parts, and independently of scatters in the movements (I) of the drive linkage (8) of the individual poles of a multipole switch. <IMAGE>
