Title: Process for the reaction of a low-molecular hydroxyl compound with a carboxylic acid halide
Inventor: MILTENBERGER KARLHEINZ
IPC: C07C69/63
Filed: 1991-02-01
Abstract: In a process for reacting a low molecular weight hydroxy compound with a carboxylic acid halide, a small amount of the acid halide is introduced into the reaction vessel and the remainder of the acid halide and the hydroxy compound are added gradually in an approximately stoichiometric ratio. The hydrogen halide formed is thus prevented from dissolving in the reaction medium. The heat of reaction to be dissipated is negligible.

Inventor: THOMAS NENNER
IPC: C25B1/00
Filed: 1979-08-16
Abstract: The invention relates to a process for the recovery and the concentration of uranium (VI) contained in an organic phase. The organic phase is treated continuously in a contact zone with an aqueous solution containing an oxidizing-reducing agent in the reduced state, said oxidizing-reducing agent being capable of reducing U+6 to U+4 in said aqueous solution. The aqueous solution employed in the process issues in part or in its entirety from the cathodic compartment of an electrolytic separation cell, which is under a direct current potential, and the aqueous phase issuing from the contact zone feeds in part or in its entirety the anodic compartment of the electrolytic cell. The process is of particular interest when applied to the recovery and concentration of uranium contained in a wet process phosphoric acid.

Title: Tube spinning assembly
IPC: D01D5/06
Filed: 1959-05-09
Abstract: <PICT:0872120/IV (a)/1> <PICT:0872120/IV (a)/2> A wet-spinning assembly 10 (Fig. 1) including a spinning tube consists of a cover portion 11b and a base portion 11a provided with a support 12 (Figs. 1 and 2) adapted to rest on the bottom of a spinning trough (not shown). The portion 11a has a rear section 14a provided with semi-annular grooves 15a, 16a supporting a spinneret 20 contained within a housing 21 and positioned by flanges 17a, 18a. The upper half of the spinneret engages the semi-annular grooves 15b, 16b in the cover portion 11b so that the spinneret and its housing are completely enclosed when the portion 11b is swung down into the operative position on top of the portion 11a. The rear sections 14a, 14b of the assembly 10 are separated from the forward sections 13a, 13b by an annular cavity 22 extending radially parallel to the face of the spinneret 20. Apart from narrow bridges 23 connecting the front and rear portion of the assembly the cavity 22 is in free communication with the coagulating liquid, which can therefore flow freely into the cavity from the coagulating bath in which the assembly 10 is immersed. The rear faces of the front sections 13a, 13b are curved inwardly at 24a, 24b to promote a nonturbulent flow of coagulating liquid from the cavity 22 into the entrance of the spinning tube 25. The latter is positioned by the shoulders 26a, 26b of the semi-cylindrical openings 27a, 27b of the front sections 13a, 13b. The inlet end of the tube 25 is supported by a tubular bracket 28 attached to the portion 11a and is provided with trunnions 30 in which are pivotally mounted the eyelets 32 attached to the arms 31 of the upper member 13b. The latter is locked in the operating position by a latching lever 35 which is pivotally mounted on the member 13b by means of a pin 36 and the lower end of which engages one of the notches on the inclined surface 33 of the bracket 28. Specification 785,893 is referred to.

The sulphonate group may be contained by a dicarboxylic acid or a dihydric alcohol. The basic nitrogenous compound may be introduced into the polyester (i) with any of the starting materials for the formation of the polyester, (ii) after formation of the polyester and before shaping, (iii) during shaping or (iv) after shaping. In examples, a copolyester from dimethyl terephthalate, ethylene glycol, and sodium dimethyl isophthalate-5-sulphonate is (1) melted and spun, 2-diethylaminoethyl nicotinate being applied to the thread while still molten, and (2) ground with tribenzylamine, then melt-spun to give fibres.

Title: Tobacco smoke filter element
IPC: A24D3/06
Filed: 1966-11-28
Abstract: A tobacco smoke filter element comprises a resilient tubular outer wrapper surrounding a filler of compressible liquid-entraining material arranged to permit axial filtering flow of smoke therethrough and has disposed therein at least one frangible capsule containing a liquid smoke-treating medium and a multiplicity of particles of active carbon moisturized with said liquid. The capsule is broken to release its liquid content into the filler by squeezing the outer wrapper. The filler is formed from conventional smoke filter materials optionally coated with a stiffening material. A single relatively large capsule or a number of capsules of small diameter, including microcapsules, may be used. Suitable encapsulating materials include hard petroleum wax, gelatine and frangible plastics. The liquid used is water, optionally including a surfactant, flavourants such as lemon oil, decongestants, or metal salts. The active carbon may be replaced by other adsorptive materials such as silica gel, zeolites or chabazites.

Patent ES-338608-A1 (ES)
Title: Method and apparatus for detecting fluid pressure variations in pre-determined time periods
IPC: G01L11/00
Filed: 1967-03-29
Abstract: For determining whether the variation in a given time period of the pressure of a fluid in a pipe 1 is above or below a predetermined value, the pipe 1 is connected to a fluid reservoir 2 by a pipe 3 comprising a valve controlled by a solenoid 4, and branch pipes 6a, 6b connect the pipe 3 at opposite sides of the valve to chambers of a differential pressure device. The fluid in reservoir 2 is maintained at constant pressure so that when the pressure in the pipe 1 increases above said constant pressure by a predetermined amount the device 6 closes the contact 16 to energize the relay coil 14. A contact 15 then closes to energize the solenoid 4 for 5 seconds to open the solenoid valve to equalize the pressures in the reservoir 2 and the pipe 1. On returning to its inoperative position the contact 15 momentarily energizes a relay coil 17 to close a contact 18 for one minute. Thus if before the end of such minute the fluid-pressure in the pipe 1 increases sufficiently to cause the device 6 to close the contact 16, a relay coil 19 is energized via the contacts 16, 18 to energize a solenoid 20 to close a valve 21 controlling the flow of fluid through the pipe 1.

Title: Improvements in or relating to Freezing Method and Apparatus
IPC: A23L3/375
Filed: 1967-04-07
Abstract: Fruit juice is introduced into a vessel 1 via a metering device and atomizer 5 and is frozen during countercurrent flow with cold gaseous carbon dioxide introduced through injectors 2. Frozen granules are withdrawn through a lock chamber 6. A compressor 10 draws carbon dioxide from the top of the vessel 1 through a bath 8 to remove entrained liquid and passes it through a drier 11 and a separator 12 to be recirculated through a duct 16. A compressor 13 passes a part of the recirculation stream through a heat exchanger 14 in which it liquefies prior to passage through expansion nozzles 3 into the injectors 2. The rate of gas flow through the vessel 1 is adjustable and the temperature of gas at the injector 2 may be adjusted by varying the proportions of gas which are recirculated directly and recirculated through the heat exchanger 14. The temperature may alternatively be adjusted by a reheater in the duct 16, by including a reservoir subject to atmospheric heating in a valve controlled line between the two recirculation paths, Fig. 2 (not shown), or by using a liquefied gas supply as the cold input of the circuit, .Fig. 3 (not shown). Preferred operating conditions are disclosed. The process may be carried out continuously or batchwise.
