Title: Remote control of an electrical appliance - by means of acoustic signal from microphone transmitted over normal telephone circuits
IPC: H04M11/00
Filed: 1974-12-02
Abstract: Remote control of an electrical appliance is by means of an intermittent acoustic signal. The system uses a microphone, an amplifier, a filler, a monostable circuit with relay and a timing relay. The amplifier supplies a first relay triggering signal from the signal furnished by the microphone. The monostable circuit receives this first triggering signal, and is actuated into a given state during a first determined time period on reception of the amplifier signal. The timing relay is operated after a second triggering signal furnished by the monostable circuits relay is applied to the timing relay during a determined time period. The duration of the second signal being greater than that of the first. The timing relay remaining in its actuated state after the duration of the second signal and whilst the second triggering signal is present.

Patent FR-2283488-A1 (FR)
IPC: G06F3/048
Filed: 1975-09-02
Abstract: A biprogrammable computer is provided with an operator actuable selector switch. Each position of the selector switch of the computer assigns the keyboard, the console and the display to a selected one of the two programs in progress, so that the data entered by the keyboard is automatically transferred to the memory zone allocated to the program selected at the same time the display displays messages of the selected program. If the program not selected by the selector switch must alert the operator to some abnormalities, it activates a lamp and an associated buzzer. The operator after the end of the keyboard operation, actuates the selector switch and removes the cause of the abnormality. Registers are provided for storing the point of interruption of a program being processed, as well as information for determining if the data being entered by the keyboard relates to the program selected.

Title: Vehicle deceleration rate indicator - uses mercury globule moving in sealed sloping tube to touch contacts and activate electric lamp circuits
IPC: B60Q1/44
Filed: 1975-12-04
Abstract: The rate of acceleration or deceleration of a motor vehicle is indicated to the driver of a following vehicle by a system of lights on the rear of the vehicle. This prevents the following drives from taking dangerous braking action when relying only on vehicle stop lights. A mobile weight (1) comprising a mercury globule moves by inertia in a sealed tube (2) mounted in a polystyrene block (3). A spirit level (4) permits adjustment wrt the horizontal plane. During deceleration the mercury globule is projected along the tube to a level determined by the rate of deceleration rate. Contacts (9, 10, 11, 12) are made to successively cause the lamps (19, 20, 21) to illuminate. A conventional stop lamp (24) is also included.
