Title: Gas-blast circuit breaker
Inventor: ZUECKLER KARL DR RER NAT
IPC: H01H33/915
Filed: 1981-08-28
Abstract: The invention relates to a gas-blast circuit breaker having two stationary switching elements which are in the form of nozzles and having a blowing device (blowing-out device, blasting device) which consists of a piston and a cylinder. In order to achieve particularly good guidance of the arc between the switching elements, an insulating device, which is provided to reduce the incident-flow cross-section, is attached to the end of the stationary switching element (2) and is designed, while maintaining a specific distance (a1) from the other switching element (1) which distance is governed by the permissible electrical field intensity, such that a flow cross-section remains between the switching elements (1, 2) which is approximately twice as large as the internal unobstructed cross-section of the switching elements (1, 2). The invention can be used in the case of gas-blast circuit breakers. <IMAGE>

Title: Loading area or platform with lug-like holding members assigned thereto for lashing down load-securing ropes or the like
Inventor: FRANK SIMON DIPL ING
IPC: B62D33/037
Filed: 1981-09-17
Abstract: The invention relates to a loading area or platform, in particular made of light-metal elements arranged in a platform frame or the like of a conveying vehicle, with platform gates at least partly surrounding it like a frame in the position of use and being capable of being swung out of said position around hinge pins, and with lug-like holding members assigned to the loading area for lashing down load-securing ropes or the like, said holding members being attached rotatably to annular shafts. The loading area or platform is to be improved such that the holding members do not appear as parts which always protrude or even prevent the platform gate from swinging down; in addition, it is intended that these holding members are able to be used without a problem both with the platform gate standing and also with it swung down. This is achieved by virtue of the fact that hinge pin/s (13) and annular shafts/s (13, 33) are approximately flush with one another, the annular shaft (13, 33) preferably running parallel to the pivoting pin (22) of a joint of the holding member or tie ring (25). In addition, it is intended that bearings (12, 15) which receive the hinge pins (13) and the bearing/bearings (21) of the annular shaft (13, 33) be arranged next to one another. <IMAGE>

Title: Method for strapping air coils and strapping machine for carrying out the method
Inventor: BIEBER PETER ING GRAD
IPC: B65B15/04
Filed: 1981-09-25
Abstract: In the method for strapping air coils (3), the latter are blown directly from the spindle (2) of an automatic winder (1) by means of compressed air directly onto a transfer spindle (6) of the strapping machine (9). By withdrawing the winding spindle, the air coil (3) is stripped within a workpiece holder (7), in which it tips over and becomes centred in the process in such a way that its connection ends (4, 5) acquire a horizontal position. The workpiece holder (7) is then fed by means of a longitudinal transporting device (8) to a transfer station (18) and after carrying out an electrical test is passed by the transfer station tongs (19) to the strapping operation, or is rejected. In the strapping machine (9) for carrying out the method, the transfer spindle (6) projects through a bore (15) in the workpiece holder (7) while an air coil (3) is being received, from which said spindle is removed by withdrawing. The workpiece holder (7) is matched to the dimensions of the finished coil type in each case and is therefore held replaceably. It is advantageous for a plurality of identical workpiece holders (7) to be inserted in pockets (17) which are mounted at equal spacings on the rotating belt (8') of the longitudinal transporter (8). <IMAGE>

Title: Synchronous motor which is energised without sliprings
Inventor: RADMER ALFRED
IPC: H02K11/042
Filed: 1982-05-10
Abstract: In the case of a synchronous motor which is energised without sliprings via rotating energising rectifiers, a series circuit composed of two thyristors connected in the forward direction of the energising current is provided in parallel with the energising winding in order to provide protection against the rotor AC voltage which is induced during the asynchronous acceleration. These thyristors are triggered (turned on) as a function of voltage by a triggering device (14). The triggering device (14) has two unbalanced branches (21, 22). The first branch (21), which is connected to the control electrode of the thyristor connected to the negative terminal, has (after a diode (23)), one or more series circuits (25, 26, 27) composed of in each case one auxiliary thyristor (28) with a zener diode (29) in the control circuit, and has voltage-dependent resistors (30). The second branch (22), which is connected to the control electrode of the thyristor which is connected to the positive terminal of the energising winding, consists of a series circuit composed of a diode (24) and voltage-dependent resistors (34). The value of the response voltage of the voltage-dependent resistors (34) in the second branch (22) is less than the value of the response voltage of the voltage-dependent resistors (30) which are contained in the corresponding series circuit (25, 26, 27) in the first branch (21). <IMAGE>

Patent DE-3231016-A1 (DE)
Title: Planetary gear with circulation lubrication
Inventor: KROENERT CURT
IPC: F03D80/70
Filed: 1982-08-20
Abstract: This planetary gear (8) is adapted to the operating requirement of current-generating wind-driven power stations. It is designed so that, seated on the top of a high machine tower (2), it generates scarcely any vibrations, specifically both from the point of view of this mechanical construction and as a result of its lubrication. For the compact and light-weight design, the generator (19) is flanged directly on the gear (8), and the hub (5) of the wind-power machine (4) is arranged cantilevered on the drive shaft (7) of the gear (8). At the same time, the gear (8) is rotatably mounted about its mid-axis (12) on its opposite end faces (18, 18a) and is supported in a sprung manner in a symmetrical arrangement by two torque supports (15). The lubrication comprises two systems, on the one hand the circulation lubrication and on the other hand a splash lubrication. The automatic change-over to the latter takes place by means of a control device (29) when the current supply is cut off and consequently the mechanically stressed parts of the gear (8) are relieved. The splash lubrication is caused by a bypass (25) which bridges a shut-off valve (23) in the run-off pipe (21) of the lubricating system and the highest point of which projects above the lower regions (27) of the gear. <IMAGE>

Title: Drive and evaluating circuit for a differential measuring probe
Inventor: BERGMANN ECKHARD DIPL ING
IPC: G01R29/12
Filed: 1983-03-16
Abstract: A drive and evaluating circuit for a differential measuring probe (1) has an oscillator circuit (22, 7, 8) for generating a first control signal (5) of fixed amplitude and a second control signal (6) of the opposite phase, the amplitude of which can be varied with the aid of a digital/analog converter (20) driven via a counter (18). The measurement output signal of the differential measuring probe (1) is amplified in a rectifier circuit (9, 10, 11) and smoothed. When a first predetermined threshold value is exceeded, the output signal of the latter triggers a change in the amplitude of the second control signal (6) in the first direction and, when it drops below a second predetermined threshold value, a change in the amplitude of the second control signal (6) in the opposite second direction. The changes triggered can be calculated in a storage and computing circuit (18, 27, 28, 29) and are indicated as measurement value via a display device (26). <IMAGE>
