Title: Apparatus for adjusting the longitudinal feed motion of the feed bars of a transfer press
Inventor: LEBBAEUS ROLF
IPC: B21D43/05
Filed: 1986-11-24
Abstract: The invention relates to an apparatus for adjusting the longitudinal feed motion of the feed bars of a transfer press in a defined starting position, having a cam mechanism which is driven synchronously by the drive of the press and the output member of which is connected positively, via a plurality of intermediate members, to the feed bars. The aim of the invention is to simplify the construction and reproduce the outlay on control for the solution. The intention is at the same time to improve functional reliability by eliminating possible sources of faults and to ensure transmission of the functioning of the cam mechanism to the feed bars in a manner which is independent of the feed bar stroke and is free from distortion. The object consists in designing the apparatus in such a way that only one releaseable coupling is required in the power transmission path between the cam mechanism and the feed bars. According to the invention, this is achieved by virtue of the fact that a multi-stage gearbox (6) is arranged in the mechanism linking the cam mechanism and the feed bars (10). <IMAGE>

IPC: E02D27/48
Filed: 1987-12-22
Abstract: For producing piles in the earth, a pilot bore (31) is first of all produced using a drill string (10). Cutting jets (33) are injected into the earth from nozzles (25) of the drill string (10), as a result of which a widened borehole (34) is produced. Before a hardening material (38) is fed through the inner string (12), a release layer (37) consisting of a release agent (35) is produced, which is lighter than the hardening material (38) but heavier than the cutting fluid. The release layer (37) floats on the hardening material (38) and prevents contamination of the latter with earth material and washing-away of the concrete by the cutting fluid. The drill crown (13) which produced the pilot bore (31) is blown off prior to injection of the hardening material (38). <IMAGE>

Title: Clamping device for the firm clamping of a linearly movable rod
Inventor: SCHROEDER MAGDY DIPL ING DIPL
IPC: F16B2/24
Filed: 1987-12-28
Abstract: A clamping device for the firm clamping of a linearly movable rod (12) in a specific position possesses two clamping portions (15, 16) adjustable relative to one another by means of an adjusting device (26). The rod (12) passes through the two clamping portions, and the resilient connection (18) is located on one side of the rod, whereas the adjustable device (24, 26, 29) is arranged on the other side of the mid-axis of the rod (12). By means of the adjusting device (26, 24, 29) designed as a piston/cylinder device, the two clamping portions (15, 16) are spread open relative to one another, so that the piston rod (12) can move to and fro freely in the two bores of the clamping portions (15, 16). In the event of a pressure drop in the piston/cylinder device (24, 26, 29), the spring force of the resilient connection (18) presses the two clamping parts (15, 16) towards one another again and the clamping portion (16) is thereby clamped against the outer face of the piston rod (12). The invention is used for particular preference as a safety clamping device for the firm clamping of the piston rod of a piston/cylinder arrangement in a specific position in the event of a pressure drop in the hydraulic system. <IMAGE>

Patent DE-3811496-A1 (DE)
Title: Luminaire having a plurality of light sources of low-voltage halogen lamps
Inventor: STUMPMEIER FRITZ DIPL ING
IPC: F21Y101/00
Filed: 1988-04-06
Abstract: A luminaire which is fitted with 19 or 20 low-voltage halogen lamps for mains voltage, for example 220 V, which are connected in series and for which, therefore, no transformer is necessary. For the purpose of object illumination each lamp is flexibly fastened to the housing. A lamp can consist of a plurality of housings which, however, are electrically connected to each other in series, for example 2 housings having 10 lamps or 4 housings having 5 lamps. The problem that in the case of series connection the current fails when a lamp has burnt out is augmented by the fact that, when halogen lamps are used, in contrast to normal filament lamps, it cannot be detected from outside which lamp has failed. For the purpose of pointing out which lamp has failed, an optical signal is to be given. Two systems are proposed according to the invention. System 1, the failed lamp is provided with a bypass via an NTC thermistor resistor which heats up when a lamp fails and thereby reduces its resistance and lets the total current pass for the further lamps. System 2, in the event of the failure of a lamp the current flow of the lamps is blocked; the failed lamp, however, is indicated by a signal lamp. This solution is preferably provided for larger electrical ratings (powers). Only the use of one of these solutions makes a series circuit usable, which in principle is desirable on the basis that it does not require any transformer.
