Title: Exercising and amusement device - consists of circular foot plate and compression spring attached to vertical handle
Inventor: FRITZSCHE HERBERT DR MED
IPC: A63B25/08
Filed: 1976-11-05
Abstract: An exercise and training toy consists of a circular plate to which a vertical handle is attached. On the underside of the plate, a compression coil spring is located. When a person stands on the circular board, without touching the ground, the spring is compressed thus it stores some energy. In order to move along, the person on the board can induce vertical oscillation which is increased by the stored spring force. Since the spring leaves the ground when it extends, lift as well as lateral displacement is produced by the equipment.

Title: Electronic control for IC engine carburettor - has proportional plus integral action with stabilising delay input
Inventor: ANZAI MAKOTO
IPC: F02D41/14
Filed: 1976-12-08
Abstract: A sensor in the engine exhaust produces a signal which is compared with a set value. The difference is fed into a proportional amplifier (44) and an integrating amplifier (46) whose outputs are combined in an adder (48). The resulting signal is used to control solenoid valves regulating the air fuel mixture strength. A two way switch (58) on the input to the amplifiers disconnects the incoming differential signal and instead puts a constant signal from a potentiometer (78) onto the integrator (46) only. At the same time a switch (76) disconnects the proportional amplifier and inserts an additional feedback. The switches are operated by a coil (94) energised when a gear change (102) is made and thus eliminate transient effects following a gear change.

IPC: H04N1/419
Filed: 1977-04-30
Abstract: The fault correction method is carried out during transmission of graphical data by means of electrical signals. These signals represent in the transmitter light values of successive image points. These values are obtained by line by line sweep of the document. The electrical signals of each line image are converted into code words. The number are eventual length of the code words covering a line image are variable. These code words are transmitted towards a receiver in combination with characteristic signs of the end of a line image. The cord words are reconstituted in the receiver in the form of an electrical sign train corresp. series of image points. The signals being put into memory. The number of image points of each image line constituted from the signal train are compared with a predetermined value. If there is a difference between the number of image points of a line and the predetermined value a fault correction is made. This fault correction in the disturbed line consists of comparing the signals of this line image with corresp. signals in memory of the preceding line image.

Title: Subscriber's telephone monitoring- protection circuit - indicates wrong position of relay contact to exchange by voltage drop across resistor
Inventor: HARTMANN KARL DIETER ING GRAD
IPC: H04M1/738
Filed: 1977-08-01
Abstract: The circuit is used for monitoring and protecting the telephone in a subscribers home or office; it includes several relays (GUI, GUII, nsa). If the relay contact (nsa) is in the wrong position when the handset is replaced the voltage wrong position when the handset is replaced the voltage drop across a resistor causes the exchange selector to provide a current which brings the relay contact to the correct position. A first rectifier bridge supplies the selector when the handset is on its rest, and a second rectifier bridge supplies the whole circuit when in readiness for speaking or dialling, the voltage across the resistor being utilised by one half of each bridge. This arrangement represents a saving in relay contacts. With a high ohmic resistor in series with the first bridge the danger of damage to the circuit by lightning is appreciably reduced.

Title: Brushless machine rotor earth fault monitor - detects voltage across blown fuse and inductively couples it to coil of stationary oscillator
Inventor: HOERINGKLEE MANFRED ING GRAD
IPC: H02H7/06
Filed: 1978-07-08
Abstract: The monitor determines earth currents in potential free circuits. The earth fault signal is contactlessly transmitted to a stationary circuit. The detector includes a fuse (9) earthed at a point at which a fault is unlikely. An "earth fault" signal is derived from the presence of a voltage across the fuse (9) after it has blown. The signal is transmitted to the stationary circuit through an inductive coupling circuit (11). An oscillator in the stationary circuit has a coil (14) inductively coupled with the coupling circuit coil (11) when passin it. Its damping is then decreased or increased.
