Patent FR-2220282-A1 (FR)
Title: Plastic measuring syringe - with graduations printed on piston stem
IPC: A61M5/315
Filed: 1973-03-09
Abstract: Syringe, for liq. prods., comprises a cylindrical body with a flat base and an inlet orifice; two peripheral ribs at the other end are slightly smaller than the dia. of the stem which acts as a piston. The ribs assure good sealing of the piston, which is marked with graduations which can be arranged to show any desired unit of vol. The number is read off opposite the edge of the syringe body and indicates the vol. of the liq. drawn into the syringe. The top of the piston stem is fitted with a knob for manipulation purposes. The graduations can be read even if the syringe is introduced into a relatively narrow container, with opaque walls. The syringe can be made from synthetic materials; the piston may be made from a rigid plastic, such as polystyrene, while a more pliable plastic, such as polyethylene can be used for the syringe body with its sealing ribs. Possible shrinkage of the body would only increase the sealing effect of these moulded ribs. Printing of the graduations can be effected cheaply by the silk-screen process.

Title: Frequency shift modulated data transmission presence detector - has improved efficiency by replacing limiter noise with constant frequency
Inventor: LAURENT PIERRE
IPC: H04L27/148
Filed: 1975-02-25
Abstract: Digital or sampled data is transmitted by frequency shift modulation of a carrier frequency. Limiter noise is replaced by a signal which does not affect the signal demodulator output and which is obtained by adding part of the received signal to a constant frequency. This improves efficiency of a presence detector. A receiver produces signals at an IF which is coupled to an adding circuit which also receives a constant frequency signal. A limiter is followed by filter circuits and detectors at the inputs to a comparator to obtain binary output signals. A presence detector comprises a rectifier circuit with a comparator to which a threshold level signal is applied. This level is adjusted as required for recognition of signal presence.

Title: Aniline prepn by reduction of nitrobenzene - using two step hydrogenation with adiabatic second step
IPC: C07C209/36
Filed: 1975-04-04
Abstract: Aniline is produced by catalytically hydrogenating nitrobenzene in a two step process, in the first step heat of reaction is withdrawn and in the second step hydrogenation if continued with withdrawing heat. The first step is pref. carried out at 160 - 400 degrees C until 70-99% conversion is attained pref. using a molar ratio of hydrogenation gas to nitrobenzene of 5:1 to 20:1 and the second step is continued to max. conversion, e.g. 99.5 to 99.99% conversion. The hydrogenation gas, which may be a cooled (0-100 degrees C) part of recycled hydrogenation gas, is pref. added in an amt. necessary to keep the temp. in the second step 400 degrees C and at an entrance press. of 1-10 atm., pref. 1.7 to 3.0 atm. The catalyst used in the first step, which may have lower activity than the second step may also have larger granule size. The process provides improved control of nitrobenzene hydrogenation temp. and increases total vol. of catalyst charge in the reactor, along with high conversion rates and reduction in the required excess of hydrogenation gas, eliminating irregular feed distribution.
