Patent DE-3440656-A1 (DE)
Title: Joint between two pipes which approach one another at an angle
Inventor: DUELL GUENTHER
IPC: B62K19/20
Filed: 1984-11-07
Abstract: The invention relates to a joint between two pipes which approach one another at an angle with intermediate connection of a joint plate. In order to increase the loading capacity of the joint, not only is the pipe slotted in accordance with the thickness of the wall of the joint plate, but two slots are made in the joint plate in accordance with the thickness of the wall of the pipe and the diameter of the pipe. In this way, not only is the fitting-on depth between pipe and joint plate increased but, above all, the weak point in the slot base of the pipe slot is moved out of the area of greatest stressing; the latter is found in the region of the final contour of the joint plate. After fitting together, the pipes are soldered to the joint plate. In order also to be able to replace sleeve connections by this kind of joint, further proposals are made which, above all, permit cold-drawn pipes to be soldered in the joint area in such a way that the application of heat is very small and the thermal material weakening brought about by this is minimal.

Title: Price-calculating balance
Inventor: ERBEL WILHELM
IPC: G01G19/414
Filed: 1984-11-22
Abstract: In a price-calculating balance, the load pan is normally used only for supporting the product the weight of which is to be determined by means of the balance. To simplify the handling, the unit price is not always entered by hand via a keyboard, but is contained under a specific code in the memory of a computer, which either is accommodated directly in the respective shop balance or else is located in a central computer assigned simultaneously to a plurality of balances. So that even a large product range together with its unit prices can be stored in this way and the associated code list fixing the relation between the code numbers and the product sorts remains easily and readily readable, it is proposed to provide the load pan of the balance with the code list.

Title: Handle for a forearm support
Inventor: ESCH HANS
IPC: A61H3/02
Filed: 1985-03-19
Abstract: In order to improve the use by, serve as orientation for and to improve the recognisability of a disabled person, the handle of a forearm support is given a special anatomical shape, equipped with a cylindrical bore and with a recess on the upper side of the handle which can receive a battery-driven illumination device including the means for switching on and off. This device can be operated from the top with the thumb or index finger without having to let go of the handle or having to fear slipping off. To this end, the handle was given an appropriate anatomical shape and due to the shape fixation of the fingers on the lower side of the handle and slipping were largely prevented by means of a bead on the upper side of the handle. It is thus possible for the disabled person to use the forearm support without impediment and to switch on the lamp by pressure of a finger, and this results in improved recognisability of the disabled person in the dark and permits the disabled person to orient himself using the lamp and to find objects in the dark without losing security on standing which was not possible with the conventional forearm supports.

Title: Process and tunnel kiln for firing carbon- or graphite-containing mouldings
Inventor: SCHROEDER PAUL
IPC: F27B9/30
Filed: 1985-06-14
Abstract: A process and a tunnel kiln for firing carbon- or graphite-containing mouldings, in particular anodes, for aluminium production are improved in such a way that the sheathed mouldings are, after preheating, heated to a suitable temperature for complete removal of the binders and complete degassing of the mouldings in a stream of flushing gas in cocurrent with the direction of migration of the mouldings and passed into the firing zone, it being intended for the flushing gas stream to be low in or free of oxygen, in order to pick up the carbonization gases and vaporization gases issuing from the mouldings and to pass them into the firing zone unburned, but at a temperature which prevents any condensation. In the firing zone, the burning of these carbonization gases and vaporization gases takes place, which thus represent an additional fuel. The process can be carried out continuously in a tunnel kiln which is fitted with corresponding tunnel kiln sections, and the kiln section comprising the degassing zone, the firing zone and, if appropriate, a precooling zone designed with recuperators should be secured against ingress of false air on both sides by inlet and outlet locks.

Title: Device for monitoring the stress-strain condition of clamping bolts
Inventor: HUETTNER HORST DIPL ING
IPC: G01B5/30
Filed: 1985-07-02
Abstract: Alternating magnetic forces can cause loosening in the stator laminate stack, as a result of which there are changes in the magnetic and electric values. The destruction of the insulating layer of the individual laminations can also occur. The object of the invention is the early detection of such loosening phenomena. The clamping bolt (1) is arranged in the clamping plate (5). The clamping bolt (1) has a bore (2) in which a strain gauge (3) is arranged. The arrangement of the strain gauge (3) is such that, on the one hand, it is protected and, on the other hand, bending stresses exert no influence on it. The signals emitted by the strain gauge (3) are fed outwards via the signal lines (4) to a display device. The cavity (9) of the bore can be sealed with a filler in order to avoid wire jumpers. <IMAGE>

Patent DE-3614477-A1 (DE)
Inventor: MACKENTHUN HOLGER
IPC: H04B5/00
Filed: 1986-04-29
Abstract: An apparatus for bidirectional data transmission includes a predominantly stationary part with a data line connected to cause a phase shift of an osicllator signal for transmission to a predominantly mobile part. AC signal components of the oscillator signal received by the mobile part are formed into square wave pulses and a difference between high and low states of the pulses is indicative of a phase shift. During the high and low states, positive signal edges of a second oscillation frequency are counted and compared to one another so that predetermined difference causes a status change on a data output line in the mobile part.
