Title: Locomotive transformer current surge suppressor - initiates switch-on relative to total transformer flux value
Inventor: UBL HEINZ DIPL ING
IPC: H02H9/00
Filed: 1974-05-21
Abstract: The circuit arrangement is used for complete or partial suppression of switch-on surge in a transformer, especially in a transformer in an electric locomotive. TRansformer switch-on follows depending on the instantaneous values of the total transformer flux formed from the remanence flux and the exciter flux, effective at switch-on. The total instantaneous flux value is determined specifically by a comparator (7) that initiates a switch-on of the transformer, via the input (supply) mains, (1) depending on this value. The control device (8) is connected directly to the pantograph (2) and also has an input (6) from the transformer (4). Operation of the switch (3) when the input values are similar avoids the production of transients.

Title: Repositioning system for numerically controlled machine tool - position at interruption is stored and tool repositioned
Inventor: TIETZE ECKART DIPL ING
IPC: G05B19/4067
Filed: 1974-06-29
Abstract: A numerical controlled machine tool has a built-in facility for measuring and storing worktable positions in the event of an interruption or toll breakage. The general overall mode control unit has a number of selection inputs and communicates with the data processing unit that provides all necessary interpolation relating to cutter path. Direct outputs from the interpolator connect one logic with the control loops associated with the drives for each axis. Each motor drives a position transducer providing the necessary feedback. The control circuits for the N.C. system also generate inputs for an up-counter and a down-counter. In the event of an interruption resulting in a requirement to move the tool temporarily away from the programmed path, the interrupt position may be stored.

Abstract: The photographic enlarger with automatic focussing control operates an a simple lens formula. The focal length of the lens of the enlarger is not a constant value, but has a linear relationship to the value of the deflection from the true path. The enlarger itself is constructed such that the lens is moved in relation to the negative carried by the enlarger head by means of linkages, in such a way that a constantly focussed image is produced on the enlarger base board no matter what magnification is subsequently used. The arrangement also allows photographs of different sizes to be easily enlarged.

Title: Measuring circuit for frequency drift of carrier transmissions - uses phase locked loop multipliers and logic elements
Inventor: BRUECKNER EGON DIPL PHYS
IPC: H04B3/462
Filed: 1974-11-30
Abstract: The incoming signal is passed to two bandpass filters having pass bands of 1020 Hz and 2040 Hz respectively. Two phase locked loop multipliers multiply the two channels by factors of 256 and 64. The square wave output of one multiplier is fed to a phase delay and gating network, the other to a pulse shaper with short duration pulse output which is also connected to the gating circuit. An R-S flip-flop and differentiator feed a comparator whose two outputs give a pulse stream related to either positive or negative frequency error in the original signal. A further bistable circuit operates lamps to indicate the polarity. A monostable circuit provides a pulse train of constant amplitude and width.

Title: Nuclear fuel rod held in plate by easily released fixing - with axially slit bulbous head which snaps into engagement
Inventor: BESTENREINER GEORG DIPL ING
IPC: G21C3/33
Filed: 1975-05-07
Abstract: A fixing or retaining device for the end of a nuclear fuel rod etc. where it passes through a hole in a fuel rod retaining plate consists of, approaching the end of the rod; an annular groove of width equal to or greater than the thickness of the retaining plate, a conical shoulder, a bulge of dia. exceeding that of the hole and a conically tapering tip. This end region is axially split by one or more slits extending from the tip at least as far as the groove, thus dividing the rod into fingers of an elastic material. Preferably, the unstressed diameter of the groove exceeds that of the hole in the plate, thus ensuring a prestressed engagement. The fuel rods are reliably retained in the plate for as long as desired, but can be easily released even in difficult circumstances.
