Inventor: MONTAG BERNHARD
IPC: G01N25/00
Filed: 1980-03-04
Abstract: For making families of steady-state heat transfer coefficient curves visible, the invisible residual moisture profile obtained by exposing a moisture photogelatin layer to a gas is immersed, in daylight, in a soluble organic sulfur compound, particularly thioacetamide, and is converted into a silver sulfide line photogram. The method is used, for example, for making visible families of steady-state heat transfer coefficient curves on forced air-cooled electronic assemblies.

Title: Continuous stepped prodn. of injection mouldings as endless strand - using two injection moulding units with three dimensional movement capability
Inventor: FLORJANCIC PETER
IPC: B29C45/10
Filed: 1980-03-21
Abstract: A continuous injection moulding appts. is intended for the prodn. of "continuous but cyclically produced" articles, i.e. for the step-by-step moulding of a continuous strand with injection mouldings attached to it, or the continuous step-step prodn. of serrated racks and other uniform objects. The continuously produced moulding is advanced by one step each time the mould opens and the next step is moulded when the mould again closes. The appts. comprises at least two injection moulding units (11, 12), one on each side of the closure unit (10) and perpendicular to the vertical central axis of the closure unit. At least one of the injection moulding units can be displaced in three mutually perpendicular directions relative to the mould closure unit. The space in front of and behind the closure unit (10) and perpendicular to the plane passing through the axes of the injection moulding units (11, 12) is kept clear for auxiliary equipment, such as cutting or winding devices, printing equipment etc. for treating the resultant moulding. The arrangement using two injection moulding units takes full advantage of the hot duct principle, by which the material leading into the mould passes along a hot duct, to get joint-free connections between successive mouldings. As a result, very complicated mouldings can be produced.

Title: Process and apparatus for improving the sliding properties of the internal support in the interior of tubular workpieces
Inventor: GANSE HANS-CHRISTIAN DIPL ING
IPC: B21J3/00
Filed: 1981-06-02
Abstract: The invention relates to a process for improving the sliding properties of the internal support in the interior of tubular workpieces, in particular cylindrical tubes, produced by hammering or round kneading. In order to improve the sliding properties, which are impaired by discontinuities due to the manufacturing process, it is proposed that a lubricant consisting of a suspension of polymers be introduced directly ahead of the deformation zone in such a way that a relatively large quantity of the suspension is fed in continuously ahead of and a small quantity fed in continuously between the workpiece and the internal support and that the surface discontinuities be pressed in. The invention also relates to the apparatus for carrying out the process. <IMAGE>

Patent DE-3129048-A1 (DE)
Title: Centralised lubrication system
Inventor: MUELLER CHRISTIAN
IPC: F16N7/38
Filed: 1981-07-23
Abstract: The centralised lubrication system is used to lubricate high-speed chains, in particular for escalators and moving walkways, and chain conveyors of various designs and has a continuously operating pump, a feed line and a number of lubricant distributors dependent on the number of lubrication points. These distributors can be controlled by means of a solenoid valve which can be switched on by a contactless control sensor which detects the path of motion of the chain. In order to be able to provide the full working pressure required for lubrication immediately on demand, irrespective of the pump output, the quantity of lubricant delivered by the pump (1) during delivery strokes is fed to an accumulator (3). Arranged between the accumulator (3) and the lubricant distributors (9) is a 3/2-way solenoid valve (5). The pump (1) thus no longer acts directly, via the main line (10), on the lubricant distributor (9) but initially on the accumulator (3), in which the oil volume required for lubrication is pressurised. It is available immediately at any time from there, irrespective of the type of pressure source. <IMAGE>
Patent DE-3134525-A1 (DE)
Title: Ground-working appliance, especially rotary harrow
Inventor: GROTH HERMANN DIPL ING
IPC: A01B49/06
Filed: 1981-09-01
Abstract: The frame of the ground-working appliance (a rotary harrow is shown) is mounted on a three-point linkage of a tractor. One arm of an angle lever (10) mounted on the frame engages on the lower links of the three-point linkage of the tractor. A hydraulic cylinder (18) cooperating with a gas volume engages on the other angle-lever arm. When the working implements (32) strike an obstacle (S) the frame is pivoted in such a way that the working implements (32) move relative to the tractor in the opposite direction to the direction of travel of the latter. After the obstacle (S) has been overcome, the gas pressure in the gas accumulator generates a force in the hydraulic cylinder (18) which passes the frame back into the normal working position. The holding force of the hydraulic cylinder (18) is so high that a pivoting out of the normal working position occurs only when the forces on the working implements reach an intolerable amount. The device described ensures that the working implement (32) is protected against damage. <IMAGE>

Title: Electric coffee-making machine with a centrifugal filter
Inventor: LEUSCHNER UDO
IPC: A47J31/22
Filed: 1981-09-22
Abstract: The invention relates to an electric coffee-making machine with a centrifugal filter which receives the brewing water by means of a rotating conveying device, e.g. a rotating hollow cone, which is arranged thereon from a heated water dish arranged below it and with an appliance housing which surrounds the water dish. The object is to provide a coffee-making machine of this type, in which the transmission of vibrations from the centrifugal filter to the housing and noises due to movements of the housing parts relative to one another are ruled out to a great extent with simple production outlay and, in particular, little assembly expenditure in the manufacture of the appliance. According to the invention, this object is achieved in that the centrifugal filter is mounted rotatably on the water dish, and the water dish is held by means of elastic buffer elements on the appliance housing and is movable relative thereto, the buffer elements also providing a thermic disengagement between the heated water dish and the appliance housing. The buffer elements preferably have a number of additional functions. <IMAGE>

Title: Electric motor, especially a DC motor without a commutator
Inventor: TSCHIRNER PETER ING GRAD
IPC: H02K29/08
Filed: 1981-09-25
Abstract: In electric motors, especially DC motors without commutators, having a permanent-magnet element (3), which is connected in a rotationally fixed manner to the rotor shaft (2), and having n fixed-position sensors (6, 7), which are sensitive to a magnetic field and interact with the permanent-magnet element (3), for emitting electrical signals, it is necessary to position the sensors (6, 7) which are sensitive to a magnetic field very precisely, especially with respect to their relative angular position. This necessitates a considerable production cost. In order to reduce this cost, ferromagnetic conducting elements (8), which are arranged in front of the sensors (6, 7) in the direction towards the permanent-magnet element (3), are arranged so that they can be displaced in rotation (10, 11) independently of one another, the rotation axis coinciding with the axis of the rotor shaft (2). Deviations of the sensors (6, 7) which are sensitive to a magnetic field from their precise position can be counteracted by suitable rotation displacement of the ferromagnetic conducting elements (8). <IMAGE>
