Patent DE-3327062-A1 (DE)
Title: Quick-action clamping device
Inventor: STELTER REINHARDT DIPL ING
IPC: B25B5/08
Filed: 1983-07-27
Abstract: The field of application relates to the single-handed clamping of workpieces of different sizes for the purposes of machining on DIY drill uprights and bench drills. The object of the invention is to provide a device that enables workpieces to be quickly and securely clamped in conjunction with a low outlay. According to the invention this object is achieved with a housing, in which a clamping claw and a clamping eccentric are respectively swivellably and rotatably connected to one another on horizontally arranged shafts, is guided with a vertically arranged bore on the column of a drill upright or a bench drill. In order to clamp a workpiece the clamping claw is simply placed on the workpiece and the clamping eccentric is actuated with the toggle located on the outside of the housing. The clamping claw then swivels downwards and presses the workpiece against the bearing surface. The housing need not be locked on the column because the guide between the column and housing is tilted as a consequence of the moment generated by the clamping force.

Patent DE-3332172-A1 (DE)
Title: Disinfection apparatus
Inventor: DAVID CLEMENS
IPC: A61L2/07
Filed: 1983-09-06
Abstract: Hitherto, milk bottles for babies have been disinfected by boiling in a saucepan or by a chemical disinfecting method. In the customary boiling method, re-infection of the disinfected articles could not be ruled out, whereas the chemical disinfecting method leads to an accumulation of harmful substances in the food. These disadvantages are counteracted by a disinfection apparatus exhibiting the following features: An essentially closed housing, a base plate made of a heat-conducting material and having a surface which slopes down towards the mid-point, and a heating rod extending essentially perpendicularly from the lowest point of the surface of the base plate and made of a heat-conducting material, in the interior of which an electrical heating element is arranged. This disinfection apparatus achieves complete disinfection of the milk bottles to be disinfected.

Patent DE-3412342-A1 (DE)
Title: Method and apparatus for degreasing workpieces
Inventor: ERBEL HORST
IPC: C23G5/04
Filed: 1984-04-03
Abstract: In order to degrease workpieces by means of a solvent vapour, said vapour is generated in an evaporation chamber prior to establishing the connection between said evaporation chamber and a treatment chamber in which the workpieces have been placed. When this connection is established, there is a pressure gradient from the evaporation chamber to the treatment chamber, which causes the vapour to flow suddenly into the treatment chamber and there to condense partly on the workpieces. This reduces the time required for vapour degreasing.

Title: Method and arrangement for determining the absolute humidity of gases
Inventor: CVETKOVIC NEBOJSA DIPL PHYS
IPC: G01N21/3504
Filed: 1984-04-13
Abstract: In such a method or in such an arrangement, a laser beam is emitted within a prescribed frequency spectrum and split into a measurment beam, which passes through the gas to be investigated, and a reference beam. The intensities of these component beams and the intensity of the radiation reflected out of the gas to be investigated are measured by detectors and fed to a computer, and the absorption of the gas to be investigated is determined as a function of a comparison of the measured values of intensity in a frequency range characteristic of water, and as a function thereof the absolute humidity is determined. The measurement beam is moved cyclically in order to scan a sector of area transverse to the direction of transmission of the measurement beam with the aid of a scanner device, and the moving transmission and reflection beams are captured by detectors after exiting from the gas to be investigated, and the measured values are fed to the computer.

Title: Vertically adjustable support device for the building industry, in particular a trestle for a working platform or a support for a falsework for ceilings
Inventor: BAUMANN WOLFGANG
IPC: E04G25/06
Filed: 1984-07-25
Abstract: The invention is a vertically adjustable support device for the building industry, in particular a trestle for a working platform or a support for a falsework for ceilings. The support device has a lower component (1) with at least one column (3) and an upper component (2) with at least one strut (7) which is guided in the associated column (3) in telescopic fashion. On each column (3), a gear wheel (11) is rotatably mounted on the outside transversely with respect to the longitudinal direction of the column (3) and of the strut (7) and engages through the wall of the column (3) facing it with a longitudinal row of through-openings (19) on the side of the strut (7) facing it. The distance between the through-openings (19) corresponds to the pitch spacing of the teeth (21). A drop bolt (25) which can be raised by the teeth (21) during the rotation of the gear wheel in the direction corresponding to the rising of the strut (7) is assigned to at least one gear wheel (11) and is dropped into a gap in the gear wheel (11) in the position in which it blocks the dropping of the strut (7) and is held against a counterbearing by the outwardly adjacent tooth of the gear wheel which is loaded at least by the weight of the strut (7). The column (3) has, in the place of the drop bolt (25), a recess (32) for the drop bolt (25) to pass into. The counterbearing is formed by the strut (7) in such a way that the drop bolt loaded by the gear wheel in its blocking position presses the strut against the wall of the column facing away from the gear wheel. <IMAGE>
