IPC: G03D13/00
Filed: 1983-09-01
Abstract: The invention provides an apparatus (2;202) and a 
method for processing bulk quantities photo-sensitive film 
originally contained in a cassette.  
     The arrangement is concerned with a controlled source 
of illumination (10;224) which is initially actuated to permit 
recognition and identification of the cassette and the film 
contained therein, but to be automatically extinguished prior 
to removal of the photo-sensitive film from the cassette for 
association (by splicing) with the content of other cassettes 
to enable continuous processing and development of con­
tinuous lengths of film to be achieved.  
     A control system (38,46,48; 224) automatically ensures 
extinguishment of the source (10;224) before opening of the 
cassette is completed, thereby preventing exposure of the 
film prior to processing.  
     A safety interlock (52;112) may be provided to prevent 
actuation of the source after the opening thereof is sealed 
within a light-tight enclosure (26;220).

Abstract: The structural member, such as a pipe has a pipe wall, whose inner and outer surfaces are formed by plastic surface layers. Between the surface layers is provided a space, which is filled with a material differing from that of the surface layers. If the structural member is used as a foundation part of a structure, the space is filled with a material or a non-porous plastic for increasing the strength and stability of the pipe, while for other, that is overlying structural members, the space is filled with a lower density material, such as PUR (Polyurethane) foam, or is in the form of a cavity. Thus, the foundation parts are not subject to unnecessarily high loading and material is saved. Playing and gymnastic structures with a random spatial arrangement can be formed from the structural members.

Title: Hoisting machine with overload protection
IPC: H02H7/085
Filed: 1985-04-18
Abstract: The hoist, lifting apparatus or the like of our invention comprises at least one hoist motor, a protective controller for the hoist motor, and an overload safety device operating on the protective controller, wherein the overload safety device has a cable load force pick-up with a tension measuring bridge, an analyzer, and a mechanism for suppression of load peaks in periodic load fluctuations. The tension measuring bridge is connected with two connecting conductors to a bridge supply generator and has two output conductors for transmission of the output signal of the tension measuring bridge. The analyzer acts on the protective controller for the hoist motor. Between the analyzer and the tension measuring bridge is a frequency converter with associated frequency generator which changes the output signal of the measuring bridge into a periodic signal. The analyzer has at least one counter with an adjustable initial state, at least one analyzer controller and a frequency divider, which produces a periodic control signal as a gate pulse for the counter from a reference frequency of normal frequency. With the counter during the gate pulse the cycles are countable, which includes the periodic signal of the frequency converter. The controller is disconnected by the counter, when a given counting state during the gate pulse is equaled or exceeded. The gate pulse is so adjusted that it equals or exceeds the period of the load fluctuations.

Title: Running-up method and apparatus for starting a rotative frequence converter
IPC: H02P9/00
Filed: 1985-10-28
Abstract: Rotating frequency converters are used for the transmission of electrical power in the band from 8 MW - 90 MW from a grid system (1) at 50 Hz or 60 Hz into a railway network (2) at 162 DIVIDED 3 Hz or 25 Hz and vice versa. The starting device for the synchronous machine (5) of a frequency converter group (3, 7, 5) allows the starting of the synchronous machine (5) from 0 Hz up to the rated speed, corresponding to a rated frequency, within 8 - 10 minutes, in 3 steps, by means of a direct converter (4) without a special starter transformer and without a starter resistor, i.e. with reduced equipment complexity. At the same time, high rotor voltages when stationary and on switching, and switch-on surges on switching-over and switching the frequency converter group to the two AC networks (1, 2), are reduced. Initially, the direct converter (4) is connected to rotor windings of an asynchronous machine (3), while the stator windings of the asynchronous machine (3) are short-circuited. The adjustable frequency (fX) at the output (A) of the direct converter (4) is increased from 0 Hz to above 20 Hz. As a consequence of the rigid coupling (7) of the rotor of the asynchronous machine (3) to the rotor of the synchronous machine (5), its stator frequency increases to about 40% of the rated speed. The direct converter is then switched over to supply the stator winding of the DC-excited (6) synchronous machine (5), and the frequency (fX) at the output (A) of the direct converter (4) is increased from 40% to 104% of the rated speed. Thereafter, the direct converter (4) is switched over onto the rotor winding of the asynchronous machine (3) again, the latter is synchronised to the grid system three-phase network (1) at the outlet, and is connected thereto by means of a switch (S1). Thereafter, the synchronous machine (5) is synchronised by means of slip regulation and is connected to the railway network (2). <IMAGE>
