Patent FR-2242354-A1 (FR)
Title: Hydrated alcohols regenerated in packed vessel - water is dispelled by purge gas
IPC: C07C29/74
Filed: 1973-08-31
Abstract: Alcohols polluted by water are regenerated in a vessel packed with e.g. zeolite particles having a high affinity for water. The vessel is vibrated so that particles slowly move into a furnace zone where the alcohol is vapourised whilst the water remains in liquid form. A stream of purge gas, pref. dry air, is blown through the heated zone dispelling the water. The alcohol is re-liquified at the inlet cool purge gas and collected at a separate outlet. The process can be used for the dehydration of alcohols, e.g. isopropyl alcohol used for cleaning semi-conductors in electronics industry.

Title: Electric underfloor heating system for flats etc. - has heating elements embedded in floor around central insulating layer
IPC: F24D13/02
Filed: 1974-01-29
Abstract: The horizontal separating wall between two storage consists of a bottom layer of cement or aluminous plaster (10). In the middle of the plaster are suspension fixtures (13).

Title: Cable television distribution system - has separate return channel from subscriber on telephone line to reduce noise
IPC: H04N7/173
Filed: 1974-02-06
Abstract: The cable television distribution system comprises principle cables, from a distribution centre to which connections are made.

Title: Reheating oven workpiece feed mechanism - alternating carriers controlled so that round workpieces rotate without advancing
IPC: B65G25/02
Filed: 1974-05-13
Abstract: A workpiece feed system for round tube or bar in a reheating oven has two sets of work carriers supported horizontally by vertical pillars from horizontal beams, in turn supported by independently driven crank arms rotated by eccentric drives, so that they are raised and lowered independently. The beams are also reciprocated independently by rack and pinion drives connected to their ends, so that the workpieces, which are carried in pockets in the surfaces of the work carriers, can be lifted from one carrier and carried foward by the other carrier, as the carriers rise and fall between one another, combined with a forward movement of the receiving carrier at the moment of transfer. The drivers of the two sets of carriers can be varied so that the forward movement is reduced so much, during transfer, that the workpieces are no longer conveyed forwards, but are subjected to a rolling movement only, thus ensuring that they are evenly heated all round for controlled periods.

Title: Yarn winding device has bobbin driven by grooved roll - guiding yarn and has roll and bobbin movement to prevent yarn build up
IPC: B65H63/04
Filed: 1974-11-12
Abstract: A yarn winding device includes a bobbin supported on a pivoted arm in driving contact with a helically grooved drive roll, yarn being fed into the groove of the drive roll so that the yarn is wound onto the bobbin in the form of a cross-wound package. During winding, one of the ends of the bobbin and drive roll are oscillated in a direction perpendicular to the plane (pref. vertical) contg. the axes of the bobbin and drive roll, and the drive roll is moved so that the yarn is maintained in the groove, If a yarn breakage occurs the action of the yarn on pref. a pivoted lever causes the lever to actuate pref. a micro-switch to brake the drive roller in a controlled manner. At the same time, broken yarn acting a guide pulley operates a cam which moves an arm carrying pref. a pin to bring the pin into contact with a rubber wheel on bobbin to rapidly brake the bobbon. A build of yarn on the bobbin is prevented thereby, preventing breakage. When breakage occurs the device is shut down quickly.

Abstract: A pressure vessel to act as a water softener, fire extinguisher, oxygen flask etc., with a fibre reinforced plastics outer layer of e.g. polyethylene, blow moulded onto an inner vessel having a greater coefficient of expansion and contraction, has ribs or grooves around the outside of the inner vessel, which have sharp corners to assists location. These ribs may be rings of rectangular or triangular section or may be helical, of e.g. square section, or alternatively may be half rings, staggered alternately along the outside of the inner vessel. In a further form, grooves may be formed around the outside of the inner vessel, so that the material of the outer layer can key into them.
Patent FR-2314864-A1 (FR)
Title: Steerable airship utilising exhaust gas for lift - has thin sheet metal outer skin to resist heat
IPC: B64B1/58
Filed: 1975-06-20
Abstract: The steerable airship derives its lift from the exhaust gases ejected by its propulsion engines. The skin of the airship is made from thin sheet metal with local areas of stainless steel where extra heat resistance is necessary. To increase the lift from the exhaust gases, additional fuel may be burnt using residual oxygen so that temperature is increased and gas density reduced. The altitude of the airship can be controlled by adjusting the temperature of air flowing into the airship gas bags by mixing the exhaust gas with fresh cold air. Using exhaust gases to lift the airship is much cheaper than using helium.
Patent FR-2331862-A1 (FR)
Title: Diode matrix with two systems of parallel paths - systems lie in plane and individual paths connected by diodes
Inventor: GASSMANN GERHARD-GUNTER
IPC: G11C17/06
Filed: 1975-07-09
Abstract: The diode connection between the two systems is made to a specified code. Selenium elements are evaporated through an aperture mask on crosspoints between the two conducting path systems determined by the code. They ensure separation of the two systems. After selenium elements are evaporated on the first conducting path system, the second conducting path system is produced by a second evaporation process. A change of code is achieved by simply changing the pattern of the aperture mask. Any kind of connecting technique may be used such as plug, soldering, or wire wrap. A separate power supply is not necessary.

Title: Bottle consignment sorting machine - uses photosensitive elements to detect bottle shape for comparison with memory stored information
IPC: G07F7/06
Filed: 1975-11-21
Abstract: The machine for sorting a consignment of bottles comprises a conveyor between the entry window and discharge point.
