Title: Turnbuckle
Inventor: KNECHT HERBERT
IPC: F16B7/04
Filed: 1983-11-29
Abstract: A turnbuckle for the detachable connection of a hollow profiled rail or the like to a supporting column etc., having at least one longitudinal groove which is bounded by parallel edges, of a framework is constructed having a U-shaped bracket which can be pushed into an associated chamber in the hollow profiled rail, the limbs of which bracket have mutually aligned bearing holes for an eccentric which is provided with an operating device, is supported such that it can rotate and is coupled to a flat slide which is guided longitudinally between the two limbs and has a front tongue part which interacts with a hook part which can be inserted into the longitudinal groove in a support and which is open towards the outside. In order to make possible a laterally stable clamping connection, which has a high load capacity, between the profiled rails and the support, with a simple construction and dispensing with a double eccentric which is complicated and is expensive to produce, the two limbs of the sprung U-shaped bracket are constructed at the ends over a part of their width in each case as a hook part having a hook mouth like a groove or channel, which hook mouth has an oblique surface which is inclined inwards, the tongue parts and the hook parts having such a thickness that, in the case of a turnbuckle which is inserted into the longitudinal groove in a supporting column, each hook part can be clamped to the associated longitudinal groove edging with a slight expansion of the longitudinal groove.
Patent DE-3344184-A1 (DE)
Title: Two-dimensionally acting toothbrush
Inventor: MAYER RUDOLF
IPC: A61C17/24
Filed: 1983-12-07
Abstract: This device can be classified to belong to the technical field of dental hygiene instruments. The object is to replace a toothbrush having the known disadvantages of only one direction of movement of the bristles acting upon the tooth surfaces to be cleaned by a toothbrush which, although it is manipulated, in the same way as the known toothbrushes found in every household, transforms part of the pushing movement and part of the pulling movement into a rotational movement. As a result, the bristles even cover sites on the teeth which are difficult to access and, in particular, the interdental spaces are cleaned much more intensively because the bristles work on the tooth surfaces with longitudinal movements and with rotating movements. A handle designed as a tubular sleeve slides over a round rod provided with a spiral groove, and a protuberance on the tubular sleeve projects into the spiral groove in such a way that a rotating movement is brought about with longitudinal displacement of the tubular sleeve and with support of the round rod provided with bristles. This process is illustrated in the graphic representation in Figure "A". <IMAGE>

Patent DE-3416923-A1 (DE)
Title: Window cleaning system for motor vehicles
Inventor: KOFINK WOLFGANG DR
IPC: B60S1/12
Filed: 1984-05-08
Abstract: A window cleaning system for motor vehicles is described in which a hydraulic actuation element is controlled by means of pressure pulses, controlled as a function of time, of the fluid. In comparison with known hydraulic actuation elements which are controlled as a function of travel, the operational reliability is thus improved. In addition, a pressure-dependent distribution element is described with which the fluid can be diverted to various washing points or loads in an operationally reliable fashion. The distribution element is controlled by means of electromagnetic switching elements which, however, do not carry out the adjustment process but only limit or block the adjustment path. The switching forces of these electromagnets can be substantially reduced here in comparison with known solenoid valves.

Title: Method and device for thermal measurement of mass flow
Inventor: GUTEKUNST GERHARD
IPC: G01F1/704
Filed: 1984-06-29
Abstract: A measuring device fitted with a small electronic computer is used to determine mass flow, in particular in the case of lines for heating, hot water, cold water and process liquid. If it is possible to change the temperature of the flowing medium, two quickly reacting thermometers, which can be mounted on the same pipeline with a selectable spacing, are used to measure the rate at which the change in temperature propagates. After inputting the temperature, which is intended to initiate and terminate the measurement process, as well as the spacing of two sensors and the free cross-section of the pipeline, the computer determines the mass flow and displays it on the digital display. Selectable units are, e.g., 1/s, 1/h, m<3>/h. The measurement device can also be set such that only temperature, only time or only rate can be read off.
