Title: Devices for the isobarometric filling of bottles
IPC: B67C3/26
Filed: 1976-08-12
Abstract: 1515624 Bottling PONT-A-MOUSSON SA 12 Aug 1976 [29 Aug 1975] 33541/76 Heading B8T Flow of liquid A from a vat 1 into a bottle B is controlled by a valve 26 one surface 26b of which is subject to the pressure of the liquid while the other surface 26a is subject to the pressure of air in the bottle. Raising bottle B against gasket 10 of cone 9 causes outer sleeve 11 to telescope over inner sleeve 2 until cone 9 lifts ring 21 which in turn raises ring 14 and turns air exhaust tube 12 to release valve 26 from sealing pressure by cup member 15. Valve 26 then rises from seat 6 as the liquid pressure tending to open the valve is greater than the air pressure in the bottle which acts on surface 26a via orifices 29. When the liquid level in the bottle reaches tube 12, liquid rises up the tube through orifices 13, reducing liquid pressure and increasing air pressure in the bottle. The pressure change causes valve 26 to fall on to seat 6 to prevent further inflow of liquid. Lowering of the bottle then allows tube 12 and therefore sealing cup 15 to descend to seal valve 26, followed by descent of sleeve 11 under gravity. Liquid from tube 12 drops into the bottle and the device is ready for the next filling operation. The device may be sterilized by forcing sterilizing solution back through the line, the solution injector having a neck of such shape that it contacts ring 14 and raises it together with valve 26.

In an ignition machine for shot firing &c. driven by a spring returned manually-operable spindle which is also coupled to a circuitclosing device, the ignition circuit is shorted during the return of the spindle to its initial position. As shown, the dynamo 20 is driven by anti-clockwise rotation of handle 1 through gearing linking the dynamo-pinion to the gear 4, and a control disc 6 is also loosely coupled to the handle spindle by pin 5. A circuit-closing cam 12 on a fixed pin 11 is in turn loosely coupled to disc 6 through pin 12a and cam 12 is thereby rotated provided that it has not been impeded by engagement of arm 14 thereon with pin 18 which will however have been attracted out of the path of arm 14 by field magnet 19 if the dynamo speed is adequate cam 12 carries a contact 13 connected to slipring 10 which engages contact 8 on a stationary insulating member 7 to complete the ignition circuit. The latter however is short-circuited after four milliseconds by the engagement of wiper 17 with contact 9, the wiper 17 being on a cam 16 having a pin and slot connection with cam 12. On the return of handle 1 by spring 3, disengagement of wiper 17 from contact 9 occurs only after the disengagement of contacts 8, 13 but by this time the drive has reached its initial position.

Title: Purification of vinyl chloride by fractional distillation
Inventor: ROLAND KLAUS
IPC: C07C17/383
Filed: 1965-08-06
Abstract: 1,068,708. Purification of vinyl chloride by distillation. INSTITUT FUR CHEMIEANLAGEN. Aug. 6, 1965, No. 33796/65. Heading BIB. Crude vinyl chloride, especially that produced by reacting acetylene with hydrogen chloride, is purified by introducing the crude gaseous vinyl chloride, preferably at a pressure of 3 atm. abs., into a fractionating column 4 wherein the higher-boiling impurities are condensed and withdrawn from sump 5, compressing the gas leaving the head of the column to about 9 atm. abs. in compressor 6, condensing the compressed gas in condenser 9 by heat-exchange with water or air, submitting the condensate to distillation in fractionating column 12 to expel lower-boiling impurities (e.g. acetylene), and withdrawing purified liquid vinyl chloride from the sump 15 of the column. Column 12 is preferably operated at a pressure of 2 to 3 atm. abs. The gas leaving dephlegmator 13 is returned to the acetylene/ hydrogen chloride reactor. As shown, the gas from compressor 6, before being condensed, is passed through saturator 7 in countercurrent to part of the condensate from condenser 9. The liquid leaving the base of saturator 7 is used as reflux for column 4; and the saturated gas leaving the top of the saturator is conducted via heat-exchanger 8 into condenser 9. The other part of the condensate from condenser 9 is cooled by heat-exchange with brine in cooler 10, and then introduced into column 11, where it contacts the residual vapours withdrawn from condenser 9. Part of the condensate withdrawn from the sump of column 11 is passed, together with the condensate from heat-exchanger 8, into column 12, which is heated by the crude feed gas supplied by compressor 2 to heat-exchanger 3. The remainder of the condensate from column 11 is expanded in evaporator 16, and some of the liquid is then conducted to heat-exchanger 17 where it cools the brine required for cooler 10 and dephlegmator 13. The remainder of the liquid withdrawn from evaporator 16 is pumped into the upper section of column 11. The condensate from heat-exchanger 3 is also used to cool the brine in heat-exchanger 17. The vapours leaving evaporator 16 and heat-exchanger 17 are conducted to compressor 2.

Title: Esters of natural and synthetic estrogens
IPC: C07C59/64
Filed: 1959-10-06
Abstract: The invention comprises esters and partial esters of estrogens with b (p-alkoxyphenyl)-propionic acids of the general formula <FORM:0926456/IV(a)/1> wherein R represents an alkyl group of 1 to 12 carbon atoms, and the preparation thereof by esterifying the estrogens with an acid chloride or acid anhydride of the b -(alkoxyphenyl)-propionic acids in the presence of a tertiary amine at a temperature between 0 DEG  and 20 DEG C.  Instead of the tertiary amine, an inert solvent may be used.  The esters and partial esters may be derived from natural estrogens such as estrone, estradiol and estriol, or derivatives of natural estrogens such as 17-ethinylestradiol, or synthetic estrogens such as diethylstilbestrol, dienestrol, and hexestrol.  In the case of estrogens having two or more hydroxyl groups, the esters may be mono-, di- or polyesters, or they may be mixed esters containing at least one ester radical derived from an acid of the above formula and an ester radical derived from a lower fatty acid such as acetic and propionic acids.  Partial esters may also be prepared by partially hydrolysing the fully acylated estrogens.  Estrone-3-esters prepared by the above method may be catalytically reduced to form a hydroxy group at the 17-position.  Acid chlorides and acid anhydrides of the propionic acids of the above general formula are prepared by treating the free acids with excess thionyl chloride on a steam bath or with thionyl chloride in the presence of pyridine respectively.
