Title: Overload protection circuit with optical coupling - has auxiliary section with LED coupled to phototransistor operating magnetic switch
Inventor: GUERGENS RAINER ING GRAD
IPC: H02H1/00
Filed: 1979-06-29
Abstract: The overload protection circuit incorporating an optical coupling system uses a light emitting diode (11) which operates a phototransistor (17) to control a magnetic switching device (12). This has at least one contact (121) which disconnects the secondary winding (4) of the input transormer to cut off the a.c. supply to the remainder of the circuit. Part of this remainder includes a resistance (9) in parallel with this phototransistor and a diode (10) in series with it. In the event of overload, this resistance gives rise to a voltage drop sufficient to operate the light emitting diode which is coupled with the phototransistor, and operates it, so as to operate a switching thyristor (19). The phototransistor is connected to the control electrode of the thyristor, which in turn operates the magnetic switching device. The remainder of the circuit may be an a.c. or d.c. circuit.

Title: Blast furnace charge profile determn. - from plumb bob vertical and guide tube horizontal travel
Inventor: AKIMOTO KEIICHI
IPC: C21B7/24
Filed: 1980-04-29
Abstract: A device to measure the profile and angle of repose of the charge in a blast furnace is attached to a horizontal guide tube which can be inserted across the furnace top and encloses a wire rope with a plumb-bob at the end. The rope is slung around a pulley attached to a load cell which senses whether or not the plumb-bob has contacted the charge. A first rev. counter establishes the amount of vertical movement. A second rev. counter establishes the horizontal travel of the guide tube carriage. A minicomputer calculates from these readings the profile at which the charge lies. This permits a fast determination of the charge profile by a quick establishment of the incidence of the plumb-bob on the charge and by elimination of the plumb-bob oscillations.

Title: Slip ring mounting for electrical machines - fixes component parts to each other by shear bolts to prevent relative movement
Inventor: FLUETEOTTE WOLFGANG
IPC: H01R39/08
Filed: 1980-08-04
Abstract: The slip ring body consists of a hub (1) having a welded-on projecting piece (2) shaped as a flange, plus an insulating layer (4) on its outer surface (3) on which the slip rings (6) sit. On both sides of the flanged projection (2) is an insulating dsc, next to which is each slip ring (6), and to ensure a good mechanical cohesion between the respective parts and avoid relative movement between slip rings (6) and hub (1), the slip rings (6) themselves are fixed firmly to the insulating discs (5) by axially running shear bolts (7). These bolts (7) pass through a hole (8) in the slip ring (6) and enter a blind hole (9) in the insulating disc. Additional shear bolts displaced around the insulating discs (5), connect them firmly to the welded flange-like projection (2). To prevent sideways displacement of the slip rings (6) on the hub (1), bindings (12) are provided. Thus relative movement between hub and slip rings is avoided, which movement could lead to insulation breakdown and machine failure.

Patent DE-3031868-A1 (DE)
Inventor: ROTTMAYR JOSEF
IPC: B28B7/02
Filed: 1980-08-23
Abstract: An assembly element for steel reinforced truss-type panels is cast as a one piece unit in a mold so constructed that the struts of the element are rigidly secured to the upper and lower chord directly as the result of the casting. For this purpose the mold has a lower bottom cap, an upper top base and laterally movable side wall sections. A pair of lateral side wall sections interconnects a bottom cap portion and a top base portion to form a mold part. Thus, the number of mold parts correspond to the number of struts in the element, whereby the element may be removed from the mold in spite of the fact that the top chord and bottom chord are rigidly interconnected already in the mold.

Title: Trench mortar pivot base has quick closure - and base plate of laurin:lactam to give greater resilience
Inventor: HARTMANN WERNER ING GRAD
IPC: F41A23/54
Filed: 1980-09-17
Abstract: A lock for fixing the barrel of a trench mortar to a base plate comprises a quick-release snap closure fitting over the spherical base of the barrel; the base plate is of a material having a high mechanical restoration coefficient at least in the region of the hemispherical seating and the locking zones for the closure. Pref., the base plate in this region is a laurin lactam moulding which, when heated, does not melt but disintegrates in air at 217-271 deg.C and cannot be regenerated; it has a metallic sound. The pref. commercial material is "HARDOMID" (RTM). By using for the base plate a material of considerably greater resilience than steel the forces that act upon the closure when the mortar is fired are considerably reduced. In addition, the difficulty associated with dirt getting into the steel joint and causing wear are reduced. Consequently, the life of the joint and base plate are increased and mfr. is simplified and made less expensive.
