Title: Machine tool displacement control - uses two counters operating independently from phototransistors sensing position of rotating apertured disc
IPC: G01D5/245
Filed: 1976-04-12
Abstract: An electronic vernier is employed to measure displacement in a machine tool in order to control speed or to stop the moving part. Two counters operating independently from one detector provide the control signals. Three phototransistors are located in an enclosure with windows behind a rotating disc also with windows. The transistors are submitted to light and dark as the disc rotates and the signal transitions cause a monostable to generate a pulse. The monostable signals depend on direction and speed of rotation and are applied via gating circuits to provide signals for two counter channels. Each channel has count up and count down signals for the counters.

Title: Multiple unit fire protection system - operates units in sequence including resetting of switching operations in reversed order
IPC: G08B17/00
Filed: 1976-12-31
Abstract: The circuit of the fire protection installation is designed to operate a number of units in sequence using a relatively small power source. After the fire the installation is remotely reset into the original operating condition. The resetting is achieved by reversing the voltage polarity of the system. The system consists of a number of fire protection units (1, 2 ... n) controlled by corresponding fire detection elements (D1...). Each unit works together with actuating elements containing an electromagnetic trigger assembly, which releases the actuating elements when fed with a voltage of a predetermined polarity. The operation is sequential in such a manner that initially fire protection unit (1) is actuated. The operation is extended to subsequent units via time element (T) by switching gear (a). The system is fitted with a switch (X), which by reversing the voltage polarity achieves the resetting of all actuating elements into their previous operating condition.
