Title: Automatic synchronisation of dispenser with mould boxes - esp. for chocolate creams, by planet gears actuating servo motor
Inventor: CERBONI RENZO
IPC: A23G1/20
Filed: 1979-05-09
Abstract: Means of determining the actual speeds of the mould plates, an operating mechanism including a motor and a reduction gear for the displacing of the dispenser by means of a cam operating levers, and means of adjusting the relative speeds of the moulding plates and of the dispenser, are incorporated in a plant for the prodn. of chocolate creams, liqueurs, etc. There are means of correcting the speed of the motor and the reduction gear, which are energiseda as a result of the differences detected. Errors in alignment which arise between the moulds and the dispenser injecting the filling into the chocolates, are overcome as a result of the tolerances in the chains and the driving mechanism. The machine works at high speed without the continuous presence of an operator and without highly expensive electronic equipment.
Patent DE-2928809-A1 (DE)
Title: Emergency braking system for single track railway - has logic circuit responding to signals generated by track-side circuits which indicate sections in use
IPC: B61L23/14
Filed: 1979-07-17
Abstract: Where a railway network is divided into districts, use of the track by two trains is permitted. A safety braking system prevents collisions and operates in conjunction with other alarm signals. A generator produces two low frequency signals for normal and disturbed modes of operation. A high frequency signal is modulated by these signals as controlled by a selector. The output is amplified and connected to a ground loop in a particular district. An occupation signal inhibits the output when the stop control signal is zero. A modulation detector on the train senses the normal or disturbed operating mode to generate the stop signal.

This is connected to a colour sync. identification circuit (15) and an amplitude filter (17) and a sawtooth compensating decoder (16) and two limiter differentiating inverters (13,14) to give signals for a double beam oscilloscope (19).
Patent DE-2939553-A1 (DE)
IPC: G09G3/18
Filed: 1979-09-28
Abstract: In the method for controlling a multi-digit liquid-crystal display for the purpose of representing information in accordance with the multistep matrix multiplex principle, pulse storage is instigated in order to avoid time errors and to lengthen the service life of the liquid-crystal display. For this purpose, the pulses corresponding to the base pulses (SA to SH) that are to be fed to the segment electrodes of all display positions in a respectively current time-clock interval (t0 to t7) are stored serially during the respectively preceding time-pulse interval (t0 to t7), and signals corresponding to said stored pulses are used with the start of the respectively current time-pulse interval (t0 to t7) to drive the segment electrodes of all the display positions in parallel by means of an edge-triggered memory (STS) whose storage time corresponds to the time-pulse interval (T/8). The circuit arrangement for carrying out the method is intended to ensure that the signals which are to be fed in total to the individual positions of the liquid-crystal display are temporally independent of the signals causing them and determined by the information to be represented. In order for time errors which occur during driving of the control circuits by means of the information signals not to be transferred to the signals which are fed to the individual positions of the liquid-crystal display, the circuit arrangement for serial storage (SR) has shift registers which respectively correspond to the number of segment electrodes per display position, and the inputs are connected in parallel with a signal storage device (ROM). <IMAGE>

Title: Active part monitor for cable TV distribution network - has comparator circuits at branch points, whose inputs are allocated branch amplifier outputs for useful signals
Inventor: TISCHER FRIEDRICH CHRISTIAN DI
IPC: H04N7/10
Filed: 1979-10-10
Abstract: The cable TV distribution network has several distribution planes, in whose distribution points are mounted branching amplifiers. At the branching points are provided several comparison circuits (K1,K3) whose inputs are so associated with the branching amplifier outputs, as to obtain the identical, wide band rectified levels of the useful signals. To each branching amplifier output of a distribution point is associated a partial monitoring circuit (T). A fault signal appears at the direct voltage outputs of the comparison circuits when one useful signal level deviates from the other ones. Preferably the useful signals of different distribution planes are converted to an intermediate frequency. Using a carrier and modulators, prior to the supply to the inputs of the comparison circuits. The conversion to the intermediate frequency may be carried out by using a mixing product of two different frequencies in modulators.
