Title: D.C. motor current regulator with braking resistor - has thyristor slowing motor when motor current exceeds limit
Inventor: NIKOLOFF IVAN DR ING
IPC: H02P3/08
Filed: 1973-04-21
Abstract: The current regulator, for d.c. motors, has a main thyristor in series with the motor armature and excitation winding and bridged by the series combination of a braking thyristor and braking resistor. The main thyristor is turned off with a third thyristor coupled in series with a diode across it in the same conduction direction. The commutating capacitor and its inductor are coupled across the third thyristor and discharge first across the main thyristor then, after the latter has been turned off, across a diode and inductor bridging the third thyristor. After the capacitor charge has once again reversed the motor current flows back to the supply. If the current is too large for the supply to accept the braking thyristor is turned on and the motor slowed by the braking resistor.

Title: Beam control for electron beam welder - has beam focus and stability controlled by periodically deflecting beam
Inventor: PODOLA NIKOLAJ WASILEWITSCH
IPC: B23K15/02
Filed: 1973-12-06
Abstract: An electron gun produces a collimated and accelerated beam of electrons via the collimator and accelerating anode respectively. The beam is focussed onto a workpiece by coils and is deflectable by further coils. A water cooled probe (or a Faraday slit) is positioned adjacent the beam and, by a periodic signal generated as a saw tooth wave by the generator, the beam is periodically deflected across the probe. The dwell time of the beam on the probe is a signal proportional to the dia. of the beam and hence its focus. The current induced in the probe is compared with a reference signal from a generator and the beam focus adjusted accordingly by an operational amplifier acting on the focus coils.

Title: Radio limited range automatic fine tuning - locks tuning to station to avoid neighbouring broadcast reception
Inventor: HEGELER WILHELM DIPL PHYS
IPC: H03J7/10
Filed: 1974-03-09
Abstract: A radio receiver automatic tuning device with a very limited frequency range is described. The idea is suitable for application to devices such as car radios. The circuit consists of diodes and resistors attached to the output from the intermediate frequency discriminator. Two outputs are taken, namely the discriminator output and a tuning signal of which the amplitude and polarity are dependent on the amplitude and direction of detuning respectively. Two germanium and two silicon diodes are used. A small output from the discriminator indicates that a signal is on a nearby frequency, and the silicon diodes are switched on. This allows the tuning signal to be applied to a voltage dependent capacitance in the heterodyne to lock the tuning.

Title: Differential fluid electrodynamic magnetic hover transport - with right angled figure eight shaped secondary coils parallel to primary coil planes
Inventor: WEH HERBERT PROF DR ING
IPC: B61B13/08
Filed: 1974-03-14
Abstract: The principle of the system is the attainment of zero-fluid operation with the primary coil utilisation of normal fluid operation, so as to achieve the simplest possible configuration of track and vehicle layout. The coil axes run horizontally, and the secondary coils may be mounted on the vertical interior of the track longitudinal supports, with an overall height of 80 cm. The magnetic support and guiding system requires a low iron content, and is operated by inductive effect on a secondary coil system by a primary energising coil system. The coils in the latter are mounted in the form of a figure 8 with roughly right-angles corners, and the planes of primary and secondary coils are parallel. The short-circuited couls may be half-overlapped, to prevent oscillations in supporting energy - or one-third overlapped if there are three coils involved. Aluminium semiconductors may be used in individual coils for suppression of eddying effects.

Title: Hand reckoner for railway waggon coupling calculations - gives safety factor or required coupling strength according to simple formula
Inventor: ROCKINGER GEORG DR ING
IPC: G06C1/00
Filed: 1974-06-18
Abstract: A simple non linear empirical formula relating three variables is used. The device itself consists basically of two flat plates, the base one being square (12) with two perpendicular linear scales printed on it, representing waggon and train weights respectively. A slot (24) is cut in this plate at 45 deg. to these axes and with another non linear scale printed along the slot representing a coupling factor. Through this slot, carrying a second, but circular plate a short shaft (26) is mounted. The second plate (14) made of transparent plastics, has a straight line etched on it. When this line intersects any two of the scales on the lower plate, the intersection of the third scale gives the third variable according to the empirical formula.

Title: Stencil and accessories for printed charts - comprise tray and rubber stamp for lottery sheets and football coupons
Inventor: JAHNS MAX
IPC: A63F3/06
Filed: 1974-08-16
Abstract: The stencil ensures a precise crossing of the fields and the coupons by matching exactly the fields of a coupon. The desired or prescribed precision is facilitated by means of a tray etc. into which a coupon fits exactly. The stencil is then placed on the coupon and the relevant fields are crossed using, for instance, a ball point pen as hitherto. When using the rubber stamp, the crossing does not require two movements any longer, but for instance, strong pressure by hand or the aid of a little hammer etc. Instead of a cross other symbols may be required and correspondingly catered.
