Patent FR-2471097-A1 (FR)
Title: Connection of participants into telephone conference system - using comparison of signal levels to provide priority switching signal
Inventor: TREPS HERVE MARIE JEAN PAUL
IPC: H04M3/56
Filed: 1979-11-28
Abstract: The telephone conference system can have several telephone lines connected to it to permit bidirectional communication with several users. The loudest signal is given priority and a multiplexing circuit switches from one speaker to another. A number of participants in a conference are connected via two wire to four wire converters and amplifiers for transmission and reception to a large signal switching circuit. Amplifiers in the transmission circuits connect to full wave rectifier circuits to provide signals for large signal detectors. The detector outputs determine priority by comparison in logic circuits of the signal levels of all the user circuits. The outputs are applied to the switching circuit so that the appropriate signal paths are made.

Title: Vehicle angled rear view mirror system - has non-reflective mirrors including liq. crystal soln. responsive to electric signal
Inventor: JACOB KEITH DUANE
IPC: B60R1/02
Filed: 1979-12-21
Abstract: The arrangement of rear view mirrors for a motor vehicle includes a pair of mirror assemblies positioned to extend the areas of vision to the right and left rear sides of the motor vehicle. Each mirror assembly is normally nonreflective and includes a liquid crystal solution which covers a mirrored surface and which is responsive to the presence or absence of an electrical charge to render the mirror assembly reflective. Each angled mirror assembly is activated by operation of the turn signal system to provide the operator of the vehicle with an extended area of view to the rear side of the vehicle that corresponds to the direction in which the vehicle is to travel.

Title: Transportable folding operating table - has tilting and locking mechanism between folding supporting surface and collapsible height adjustable frame below
Inventor: BLAVETTE RAYMOND
IPC: A61G13/02
Filed: 1980-01-08
Abstract: The folding operating table designed so that it is easily transported to remote sites, where operations may be performed inside e.g. a tent, has an adjusting mechanism between a base frame and the supporting surface. This allows the surface to be tilted to a required angle when erected. The base frame has two side members mounted on height adjustable feet, and connected by cross members with locking devices at their ends. This supports a smaller intermediate frame which carries the adjusting mechanism and locking system. This mechanism consists of levers attached at one end to the supporting surface and at the other end to nuts which travel along a screw rotated by an operating handle at the side. The supporting surface consists of panels attached to each other by hinges.

Patent FR-2460696-A1 (FR)
Title: Evaporator and spray dryer installation for milk powder mfr. etc. - uses evaporator vapour to preheat dryer air via intermediate heat exchanger
Inventor: LAGUILHARRE PIERRE ROBERT
IPC: A23C1/12
Filed: 1980-06-23
Abstract: The installation is of the type in which an evaporator delivers concentrate to a spray drying tower supplied with hot air. The air is heated by passage through a two-stage heat exchanger. The first stage preheats the air by utilising heat from vapour generated in the evaporator. The second stage employs an external heat source to obtain the required air temp. The heating element in the first stage preheater relies on a heat transfer liq. pumped in closed circuit through an intermediate heat exchanger deriving heat from evaporator vapour. The heat transfer liq. is pumped at constant rate flow through the circuit. While the intermediate heat exchanger can be designed for direct or indirect contact, the operation of the first stage preheater is pref. indirect. When the intermediate heat exchanger is of the direct type, the closed circuit should have an overflow outlet. Pref. the closed circuit has means for controlling the temp. of circulated liq. upstream and/or downstream of the preheater section. Installation costs reduced by eliminating long pipe runs of large dia. The intermediate heat exchanger can be located alongside the evaporator so that only heat transfer liq., usually water, has to be pumped to the first stage preheater. The closed circuit pipework is of inexpensive, small dia.

Title: 4,4-Di:methyl-1,3-di:oxane prodn. from isobutylene and formaldehyde - in an aq. medium contg. carboxylic acid catalyst
IPC: C07D319/06
Filed: 1980-09-19
Abstract: (I) is prepd. by cocondensing isobutylene and formaldehyde in an aq. medium by contact with a carboxylic acid catalyst; splitting the condensn. prods. into organic and aq. phases; evapg. the aq. phase to a bottom residue; mixing this residue with an aq. formaldehyde soln.; and recycling the obtd. mixt. to the condensn. stage.

Title: Automatic disconnector for vehicle battery after accident - uses inertia and tilt switches in supply to relay which disconnects battery and electric circuit if collision or roll-over occurs
IPC: B60K28/14
Filed: 1980-11-28
Abstract: The electrical connections to an automotive battery are automatically cut if the vehicle experiences an impact or tilts beyond a certain angle. This reduces the risk of sparking in the vehicle electrical circuit after damage incurred in an accident, thus reducing the risk of fire. Normal operation of the vehicle requires operation of a push button (2) in addition to the ignition switch (6). Both an inertia switch (4) and a mercury tilt switch (5) must be closed for supply to be applied to the coil (3) of a relay (8) whose contact (1) connects the battery to the vehicle electrical system (10). A normally closed interrupt switch (7) then takes over supply of the relay coil when the push button (2) is released. A collision or rollover of the vehicle operates either the inertia (4) or tilt (5) switch, opening the supply contact (1), and disconnecting the vehicle electric system.
