Title: Colour TV signal recording system - uses two adjacent tracks for recording two processed chrominance signals of different frequencies reducing cross-talk
Inventor: UCHIMI TAKASHI
IPC: H04N9/86
Filed: 1982-06-02
Abstract: The colour tv signal recording system includes a circuit producing a first chrominance carrier signal. This signal is converted into a low band by frequency division of the chrominance carrier signal. A second signal is obtained by frequency division and frequency conversion using a heterodyne device. This second signal occupies a different frequency band to that occupied by the first signal. The two signals thus produced are recorded on adjacent tracks. When the signals are played back a frequency selection ensures that only the signal having the min. crosstalk is reproduced. The system may be applied to a domestic recording and playback machine in which the transmission band used is relatively narrow.

Title: Sequential switch for several power storing components
Inventor: MORBE MATTHIAS
IPC: B60T8/1761
Filed: 1983-09-09
Abstract: The switch is intended for inductive or capacitive components in which the power is first stored and then released according to the switching, e.g. for automatic gear boxes in motor vehicles using solenoid valves. The switch is so designed that after switching-off of one component, its stored energy is deflected for pre-excitation of the other component. The components are pref. coils (13,18) of solenoid valves of a hydraulic system in a motor vehicle, such as the anti-blocking brake arrangement, or an automatic gear box. The coils may be connected by a first switch with first supply lines, by a second switch with second supply lines, and finally the coil terminals may be interconnected by third switch. Switching transistors (12,14,17,19) are typically used for switching.

Title: Provisional protection device, of variable length and with rapid mounting
IPC: E04G21/32
Filed: 1983-09-27
Abstract: Protection device against falls, of variable length and with rapid mounting without requiring the use of tools. The invention relates to a device suitable for affording protection to people against the risks of falling, which can be adapted to the shapes and dimensions of the zones to be protected, and intended to equip premises a posteriori without modifying their structure. It consists of frames composed of a rail 1, an underrail 2 and a plinth 3, sliding each with respect to the other in order to adapt to the dimensions of the zones to be protected. These frames are supported by uprights 20 equipped with frameworks 10 comprising at their head a part 11 which retains the rail 1, and at their lower portion, a wedge-shaped piece 12 which after the passage of the underrail 2 comes to secure the body guard onto the upright from the outside. The uprights can support, at their top portion, the fastening of a hand rail of a ladder which is securely fixed to this upright after the installation of the body guard. Plates, fixed and embedded in the structure, create an enclosure of the foot of the upright in the structure without this undergoing any modification. The cover of this plate blocks the foot of the upright in the plate in order to prevent it from coming out of its housing. The plate can be used horizontally and vertically for the same use. The device is particularly intended to serve as a compensatory safety measure after the removal of the boarded flooring of a hopper and to protect openings opening over a space in the case of a construction site.
