Patent FR-2363975-A1 (FR)
Title: Plastic covering for use in plant culture - woven from bands and filaments and placed on ground
IPC: A01G9/04
Filed: 1976-09-09
Abstract: A covering to be placed directly on exposed or elevated ground, partic. to receive cultures in pots or containers placed on it, is made of thin woven strips or round filaments of an appropriate plastic material. The cover pref. contains 60 filaments per 10 cm2 in both warp and weft, and strips 2-3 mm wide. The plastic is pref. polypropylene contg. carbon black. The filaments can be obtd. by extrusion or by twisting of flat strips. The cover is partic. used in soilless culture, e.g. in nurseries and flower growing, instead of polyethylene film. It can also be used in soil culture without pots or containers, being placed on the ground between plants to hinder weed growth. The covering permits free two-way passage of water and air, and prevents passage of ultra-violet and infra-red radiation, thus hindering weed growth. It has high strength and is of low cost. Being permeable, it prevents the retention of stagnant water between the pots or containers, and hence a better regulation of watering is achieved.

Title: Suspending flocculated casein from milk - by stirring at nought to four degrees Celsius in absence of air
IPC: A23C9/123
Filed: 1976-10-18
Abstract: Putting back into suspension flocculates casein after coagulation of milk by acidification comprises cooling the coagulated m ilk to 0-4 degrees C whilst agitating in the absence of air.

Patent FR-2349869-A1 (FR)
IPC: G04G5/00
Filed: 1977-04-25
Abstract: A resettable interval timer in combination with, but functioning independently from a digital watch which provides horological information. The watch operates in two modes; the first mode displaying horological information on the display devices and the second or stopwatch mode displaying interval timing information on the display devices. In the watch mode the user can program which horological information he desires to be continuously displayed on the display devices, either hours, minutes, and seconds, or hours, minutes, and date. By depressing one of the watch push buttons the user can momentarily display month, date, and the A.M. or P.M. horological information on the display devices. A predetermined push button depression sequence can be used to reset the horological information. When a second push button is depressed a predetermined number of times within a defined time interval the watch enters the stopwatch mode. In the stopwatch mode the user can reset the interval timing counters to zero, start the interval timer, stop the interval timer, freeze the interval timing information currently on the display devices (split or lap time), return the counters to the interval timing mode, and finally return the watch to the watch mode.

Title: Cryogenic immersion freezing plant partic. for food prods. - recycles liq. carbon di:oxide by recompressing exhaust gas
IPC: B65G53/46
Filed: 1977-06-30
Abstract: Air lock valves are employed as prod. entry and exit for a pressure vessel in which the prod. is immersed in liq. CO2 under a head space of gaseous CO2 at a pressure above atmospheric. An elevator is used to lift the prod. from the liq. and deliver it to the exit. Excess gas from the head space is exhausted to a compressor which delivers it to a condenser reservoir from which liq. CO2 is returned to the pressure vessel. The air locks are pref. of the rotary or spaced shutter types. The exit pref. comprises two air lock valves in succession with an intermediate decompression space from which gas is pumped back to the headspace. Pressure inside the vessel is pref. about 6 bars and the compressor delivers at a pressure of about 12 bars. Used for rapid deep freezing of prods. esp. food prods. on an industrial scale. The installation can handle food prods. as complete items, reduced to small pieces or as particles. In partic. particles which previously tended to agglomerate are now frozen as clean, individual particles. The installation is inexpensive to buy and economic to operate because the CO2 is recycled.
