Title: Gear shaper
Inventor: MUELLER WOLFGANG
IPC: B23F5/12
Filed: 1983-04-21
Abstract: The gear shaper serves to produce profiles on workpieces and has a rotatably driven pinion-type cutter which performs a stroke movement in the direction of its axis of rotation. The pinion-type cutter is provided with a ram spindle on which a driven gear sits in such a way as to be locked in terms of rotation. The driven gear meshes with a rotatable drive part on a drive shaft. The drive part is displaceable in the direction of its axis of rotation so that an axial displacement is superimposed on its rotary movement. The pinion-type cutter is thereby given additional rotation. In this way, tooth systems with any helix angle and any helix direction can be produced.

Title: Apparatus for straightening spring-leaf blanks
Inventor: MUELLER FRIEDRICH
IPC: B21D3/16
Filed: 1984-05-05
Abstract: During driving, springs not only provide springing but also axle guidance and ensure the straight running of the vehicle. To fulfil the task of providing guidance, the springs must be perfectly straight. Since the individual leaves become curved on edge during rolling, they must be straightened by hand. This manually performed work is not always accurate and is not reproducible. The apparatus for straightening spring-leaf blanks renders all the leaves perfectly straight.

Title: Process for the continuous production of pourable sugar masses and plant for carrying out the process
Inventor: ERNST EBERHARD DIPL ING
IPC: C13B50/00
Filed: 1984-05-29
Abstract: To produce different pourable sugar masses such as fondant crème, pouring jelly and marshmallow, a substantially shared continuous process is proposed in which the main ingredients of the sugar masses are precooked in a first heating zone as far as a first residual moisture content, whereupon the precooked solution is completely cooked in a second heating zone under mild conditions to a second residual moisture content depending on formulation. The completely cooked concentrated solution forms a main stream which, depending on the type of sugar mass, is intensively mixed in a mixing zone under conditions of simultaneous heat exchange with a side stream, composed of different constituents, in fixed formulation-dependent mass ratios. The resulting mixed stream is then further processed to give the desired flowable sugar mass type, possibly with further addition of ingredients such as aroma substances, colourings, acids. A multipurpose plant intended for carrying out the process is likewise proposed.

Title: Double-beam real-time polarimeter
Inventor: SCHMIDT ULRICH
IPC: G01J4/04
Filed: 1984-12-07
Abstract: Figure 1 describes a double-beam real-time polarimeter for the polarimetric real-time testing of samples (9). In this case, the light beam (H) is split up before interacting with the substance (9) to be tested into a measurement beam path (M) and a reference beam path (R). After interacting with a reference element (5) or with the sample (9) to be tested, the reference beam (R) and the measurement beam (M) impinge in each case on a beam-splitting analyser (6, 10). The component beams (a, b, c, d) emerging from the two beam-splitting analysers (6, 10) are each assigned a photodetector. The photodetectors are connected in this case to the inputs of a measurement circuit. In accordance with the invention, the rotation, measured in the measurement beam path (M) of the plane of vibration is offset with a correction value determined in the reference beam path (R), so that the result is free from fluctuations in wavelength and temperature. <IMAGE>

Title: Device for heat recovery from the outgoing-air flow from buildings and for harnessing solar radiation energy
Inventor: ALTFELD KLAUS DIPL ING
IPC: F24J2/00
Filed: 1985-01-21
Abstract: By means of this invention, it is possible to carry out utilisation of solar energy, in addition to heat recovery, it being possible to use the device for heating e.g. domestic water in particular during the warm season, in which heat recovery from the outgoing air for heating fresh air is not suitable. The device consists of two flow ducts 2, 3 of flat design connected by a heat transmission surface, in which the fresh air flow and the outgoing air flow are guided in counterflow. The upper flow duct 2, which conducts fresh air, is provided with a covering system 5 which is transparent for solar radiation, and absorbs the incident solar radiation. By these means, the fresh air can be additionally supplied with heat. The heat losses of the device to the environment are kept low by the transparent coverings and an insulation 6 arranged on the lower flow duct 3 which conducts outgoing air. By means of a flap 4, the flow ducts can be short-circuited and sealed in relation to the environment. A closed circuit is created, as a result of which, when heat recovery is forgone, the utilisation of the solar energy - e.g. in summer for domestic water heating - is particularly efficient. <IMAGE>
