Title: TDM telephone exchange extension - has bus=bar group connections requiring no alteration to main installation for additions after second stage
Inventor: KRAUTKRAEMER WILLFRIED DIPL IN
IPC: H04Q11/04
Filed: 1978-12-08
Abstract: A four wire connected t.d.m. telephone exchange circuit provides several group connecting switches for each incoming and outgoing bus-bar of a group in the first stage. They are controlled by a group connection memory. The bus-bar extensions connect the group connection switches to part sections in the second stage. Here they can be connected through coupling points to the incoming or outgoing bus-bars of other groups in the first stage. The advantage of the arrangement is that extensions can be made in small steps. If the second stage has to be extended it is only necessary to make additional connections to the first stage group connector switches. The size of the equipment is small enough to limit interference to acceptable levels.

Title: Carrier PCM system - compares binary with clock and outputs signal reversal of state for similar states and defers one pulse for dissimilar
Inventor: GUZMAN-EDERY JORGE DIPL ING
IPC: H04L25/48
Filed: 1979-12-13
Abstract: A variation of Pulse Code Modulation (PCM) for transmission of binary control, measurement, etc. data between two points in a transmission network. The method involves using the clock pulse as a carrier and is designed as an error detection system with a data transfer rate slightly slower than pure PCM. The data for transmission (11010010) is compared with the clock pulses. Where the data and clock are the same, i.e. both 1 or 0, a change occurs in the output signal (1c). Where the data and clock are dissimilar no change occurs and the data signal is held over for comparison with the subsequent clock pulse where similarity will occur and the output will be a change. The output pulses will be of greater duration than the original data and the clock in instances where no reversal takes places. The system of modulation is termed FTM (Flank Takt(Clock) Modulation) and the signal to line should be relatively free from a d.c. component. The system has a faster data transfer rate than pulse duration modulation (PDM) or bi-phase methods.

Title: Object scanning apparatus giving high resolution image - uses ultrasonic transceiver and image compensating network with fourier transformation of matrix functions
Inventor: SCHWARZ ROBERT DIPL ING
IPC: G01S15/89
Filed: 1980-04-30
Abstract: The object scanner consists of an ultrasonic head (2), to which impulses, governed by a timing generator (3), are fed. The sound head (2) radiates ultrasonic transmission impulses into the object under examination, these signals being reflected from the object (5) and converted into electrical echo signals, after which, they are amplified (6) and fed to a full picture store (7). The reading-in to this store, takes place line for line in series, while the reading out takes place orthogonally, and the representation of the object distribution, is passed to the image compensating network (1), where an improved image signal is produced. This signal is then fed to a cathode ray tube (8) with line and frame generator (9,10), in order to construct the echo image with the desired high resolution. This forms a simpler and more flexible method of obtaining good image resolution with real-time processing.

Title: Speed regulator for cine projector DC drive motor - operated by pulse control whose pulse length is modified at low speed to maintain stability
Inventor: ACKERMANN MANFRED
IPC: H02P7/29
Filed: 1980-06-02
Abstract: The speed regulator (6) for the motor (6) generates pulses to switch a regulating transistor (5) in series with the motor and rectifier (2) output. Pulse width increases for increased speed thus at low speeds the pulses may be so narrow that speed instability results. To avoid this condition a further transistor (9) is added, connected between base and emitter of the regulating transistor (5). Its base is connected through a divider (13,14) and shaping capacitor (12) to one pole of the rectifier ac supply. A control switch (15) is placed between base and emitter. For normal operation the switch (15) is closed and the transistor (9) is inoperative. For slow speed, slow motion, the switch opens and the ac bias on the transistor (9) causes it to conduct in alternate half cycles thus blocking the regulating transistor (5). To maintain the desired speed the control unit (6) increases the pulse length thereby giving stability and correct speed.

Patent DE-3042248-A1 (DE)
Title: Delayed switching circuit for power supply - disconnects supply after given delay when equipment is moved
Inventor: BRECKEL WERNER DIPL ING
IPC: H03K17/28
Filed: 1980-11-08
Abstract: The switching circuit has a switch (4) responding to the movement of the electrical equipment (1) whose power supply (Battery) (3) the switching circuit controls. A change in the state of this switch sets a delay circuit (14-16), which interrupts or reduces the supply of current to the equipment after its delay has expired if the switch state does not change for a second time. The current supply is also interrupted or reduced on the basis of measured signal (if used e.g. in a voltmeter, ammeter, etc.). The interruption is accomplished by a load switch (12). The supply for the delay circuit is taken upstream of the load switch. The interruption depends solely on whether the equipment is moved and not necessarily on the presence of any input signal.
