Patent DE-3524087-A1 (DE)
Title: Load-controlled double-track conveyor system
Inventor: HOFFMANN HEINZ
IPC: B61B10/02
Filed: 1985-07-05
Abstract: This conveyor can be used, like the known power + free conveyors, whereever items are to be transported and stored in a suspended, space-saving manner. A driver chain which is guided in the conveyor track moves individual sets of running gear which are guided in the load track and engage via a five-action latch. By means of the latch running onto a stopper, empty sets of running gear or optionally sets of running gear loaded with material to be conveyed are stopped. Subsequent sets of running gear are also unlatched by running up against sets of running gear which are already stationary. A stopped, empty set of running gear moves back into engagement with the driver chain by loading with material to be conveyed, in the same way as a stopped, loaded running gear engages again when the conveyed material is removed. The movement of the sets of running gear is controlled purely mechanically in a load-dependent fashion by the loading or removal of the material to be conveyed. This solution is particularly cost-effective since the use of expensive pneumatic or electrical controls is avoided.
Patent DE-3527002-A1 (DE)
Title: Method for cooling the motor of a pump by wall cooling
Inventor: SARVANNE HANNU
IPC: F04B53/08
Filed: 1985-07-27
Abstract: Method for cooling the motor of a pump by wall cooling, by the dissipated heat of the motor being passed downwards in a wall (2), which surrounds the motor and whose thickness increases in a downward direction, through the seam between the parts (2, 3) into the cold pump section and into the liquid to be pumped. The problem in modern wall-cooled pumps is the corrosion in the seam between the parts (2, 3) and the heat transfer capability reduced thereby. In a pump corresponding to the invention this problem has been overcome by the seam between said parts (2, 3) being sealed essentially close to the outer edge of the seam with a seal (1) and by as large a contact area as possible being left between the inner edge of the seam and the seal. <IMAGE>

Title: Force-transmitting element for force-measuring instruments, in particular for electromechanical scales
Inventor: ZANTKE HUBERTUS DIPL ING
IPC: G01G21/23
Filed: 1986-07-03
Abstract: The invention relates to a force-transmitting element for force-measuring instruments, in particular for electromechanical scales. The aim of the invention is to use a force-transmitting element in order to transmit a compressive or tensile force from a lever onto a force sensor with improved technical properties. The compressive or tensile force to be measured is intended to be led in a manner free from interfering force and without elastic elements into the measuring body of a force sensor. The aim is to construct the force-transmitting element in an adjustable articulated fashion and free from play above and below, and to guarantee a tolerance-free spacing between the fulcrum of the transmitting lever and the measurement axis of the force sensor. The essence of the invention is that when a compressive force is to be measured the force-transmitting element consists of a rod-shaped coupling element which contains on the upper part a spherical tip, which engages in a ball cup (socket) incorporated on the underside of the transmission lever, and has on the lower part a ball cup which is supported on a spherical tip located on the upper side of the force sensor. The spherical tip or ball cup can be adjusted. When a tensile force is to be measured, the force-transmitting element consists of a frame-shaped coupling element. <IMAGE>

Title: Switch, especially for a hand-held machine tool which is operated with direct current
Inventor: BERGER GUENTHER
IPC: H01H9/06
Filed: 1986-07-07
Abstract: A switch is proposed, especially for hand-held machine tools which are operated with direct current. A contact tongue (7) which is placed under the influence of a geometric-lock spring (10) has a positive interruptor (17) allocated to it. During the rearward movement of the switching lever (13) from the switched-on position into the switched-off position, it strikes against the contact tongue (7). If the torque of the geometric-lock spring (10) is not sufficient to release the contacts (4, 8), the positive interruptor (17) tears these contacts apart from one another. In this case, in the extreme case, the switching lever (13) is also pushed back into the cut-off position by the operator, as well. <IMAGE>

Title: Process for the removal of C4-hydrocarbons from a gas mixture
Inventor: BAUER HEINZ DIPL PHYS DR RER N
IPC: F25J3/06
Filed: 1986-08-06
Abstract: C4-Hydrocarbons are to be removed by cooling and rectification from a gas mixture which contains C1- to C4-hydrocarbons, nitrogen and hydrogen. The C4-hydrocarbons should make up more than 50% of the hydrocarbons contained in the gas. In the process, the gas mixture is first cooled so much that a part condenses and is fed into the lower region of a rectifier column. From the top of the rectifier column, a gaseous fraction is drawn off which is further cooled in a heat exchanger and partially condensed, after which the partially condensed portion is added to the top of the rectifier column as reflux.

Title: Forging machine
Inventor: SCHMOLL HEINZ
IPC: B21J13/03
Filed: 1986-12-17
Abstract: The invention relates to forging machines with four rams (3) which are arranged in an X in a working plane at right angles to the longitudinal axis of the workpiece, can be moved transversely to the longitudinal axis of the workpiece and are provided with dies (2) which, in the end position of the stroke, which is close to the centre, form a closed groove, the dies (2) overlapping one another with the unused width of their working surfaces and their side faces.   According to the invention, disadvantageous oblique or oscillating movements of the dies (2) are prevented, while sacrificing the possibility of achieving a closed groove in all stroke positions, by the fact that the working units (3, 4) are arranged so as to act radially relative to the longitudinal axis of the workpiece, in that adjusting means (28) for setting and indicating the stroke end position are provided and that each die (2) can be adjusted in the working plane out of the axis of action of the driving arrangement by the amount (V), in a slide formed by the ram (3) and a crosspiece (46), by means of an adjusting device as a function of the stroke end position setting which determines the degree of forging, the amount (V) corresponding to half the difference between the total width and the used width of the die (2) corresponding to the respective groove.   <IMAGE>

Title: Process for joining moulded parts
Inventor: FLIESS FERNANDO DIPL ING
IPC: B29C65/02
Filed: 1987-02-17
Abstract: The invention relates to the joining of moulded parts to form composite bodies which, according to their function, consist of an outer sleeve and thermoplastic core. The aim is to improve the mechanical strength, the leak-tightness and stress resistance of the connection region and to improve the dimensional stability of the composite body to be produced. The object of the invention is to achieve a direct, all-round and gap-free connection at the joint contours. This object is achieved according to the invention in that the moulded parts are formed by the primary forming of a support body and, associated therewith, the re-forming of thermoplastic parts to give joint contours, in that the joint contours, in the position before the joining operation, define a joint cavity, in that the mouldings are joined by external force and, during this operation, obtain low viscosity in the connection region by energy supply and, during the joining operation, the support bodies constitute a solid encapsulation for the flowing material of the joint contours. The field of application is the production of composite bodies which consist of an external sleeve with good heat resistance and hard and brittle properties and of a thermoplastic high-voltage-resistant core. <IMAGE>

Title: Process for the selective removal and subsequent isolation of sulphur dioxide from flue gas
Inventor: ROSENDAHL ERICH DIPL ING CHEM
IPC: C01B17/60
Filed: 1987-04-29
Abstract: Process for the selective removal of sulphur dioxide from flue gas by absorption by an amine/solvent mixture and subsequent isolation of the sulphur dioxide by thermal desorption. Regenerative flue gas desulphurisation processes which operate with aromatic amines, such as xylidine, toluidine/water mixtures have not been used because of the problems occurring with them which impaired handling, such as sulphate formation, and because of the weak absorption properties. The novel process is distinguished by simple handling with respect to the absorption-desorption of sulphur dioxide and can be carried out at low temperatures. A tertiary amine/solvent mixture, containing antioxidant additives, at temperatures up to 40@C and atmospheric pressure selectively absorbs up to 10 % by weight of sulphur dioxide from flue gas. Desorption is performed with boiling of the solvent used here with n-heptane at 90@C with a release rate of 45 %. Mild operating conditions and antioxidants as additives produce simple handling and long service lives of the process mixture with respect to absorption-desorption.
