Title: Improvements in and relating to processes and apparatus for eliminating impurities during the separation of air by low temperature rectification
IPC: F25J3/08
Filed: 1950-04-24
Abstract: 678,240. Separation of air. LINDE AIR PRODUCTS CO. April 24, 1950 [May 7, 1949], No. 10099/50. Class 8 (ii) A process for eliminating impurities during the separation of air by low temperature rectification comprises scrubbing cooled compressed air with a liquid fraction of the air in a chamber 32, rectifying the scrubbed air in columns 36, 44 to produce an oxygen enriched liquid at the base of column 44, which is partially vaporized to provide vapour for the rectification, passing said oxygen-enriched liquid through either of adsorption chambers 66, 661 containing, say, silica gel which retains most of the hydrocarbon impurities, passing said partly purified oxygen-rich liquid to a separate vaporizing zone 78 wherein is formed a residual liquid containing residual impurities, and recycling said residual impurity-bearing liquid through the adsorption chambers and returning it to the zone 78. In the production of liquid oxygen, air from a compressor 15 having traversed an after-cooler 17 and a further cooler 18 has a portion cooled in an exchanger 24 and the remainder is expanded in an engine 29. The combined cooled gas traverses the scrubber separator 32, the liquid being freed from solid carbon dioxide in either of filters 39, 39<SP>1</SP>. The air from the scrubber 32 traverses a duct 35 to enter the base of the high pressure rectifier chamber 36, and filtered liquid air is fed through a duct 42 to serve as reflux in the low-pressure chamber 44 and is assisted by crude liquid oxygen from the base of the chamber 36. The oxygen-rich liquid from the base of the chamber 44 and the residual liquid from the vaporizing chamber 78 of an auxiliary condenser C are fed through ducts 58, 80 respectively to a reservoir 60, a pump 62 and either of the silica gel containers 66, 661. Oxygen gas leaves a zone 47 by a duct 73 to be condensed in the condenser tubes 74 and delivered as liquid product through a valved duct 75. Pure nitrogen leaves the chamber 44 by a duct 54 and after traversing the exchangers 24, 18 is delivered at a duct 56, and a portion used to purge the silica gel of adsorbed impurities. In a modification for the production of gaseous oxygen, the vaporization of crude liquid oxygen in the auxiliary condenser is effected by condensing a portion of cold air leaving the scrubber, and the liquid so formed is returned to the scrubber. Gaseous oxygen product leaving the auxiliary chamber is used to cool incoming air. Specification 559,252 is referred to.

Title: Apparatus for affixing slide fastner elements to fabrics
IPC: D05B3/18
Filed: 1978-03-17
Abstract: The apparatus is provided in order to be mounted on a sewing machine, and is driven by a lever (44), itself moved by the needle shaft (NB) of the machine. A device with cams and a lever (30, 50, 54, 58) converts the to-and-fro motion of the needle into a rectangular trajectory executed by a blade (57), which a stop (24) prevents from descending low enough to cut the cords connecting together the closure elements (E). The movement thus limited of the blade nevertheless allows it to engaged between these elements in order to make them progress synchronously with the fabric. By the action of a solenoid, a finger (72) can be engaged in a curvilinear slot (62), which forces the lever (44) and the parts which it drives towards the right. The trajectory then followed by the blade (57) avoids the stop, and the blade descends low enough to cut the cord. <IMAGE>

April 12, 1933, No. 10906. Convention date, April 15, 1932. [Class 40 (v).] In order to facilitate wave-band switching, and the use of a tuning-condenser marked with an exact frequency-scale, particularly in shortwave working, a valve generator or amplifier is characterized by a reactive arrangement in which condensers 3, 4, Fig. 2, are shunted across the main oscillatory circuit 1, 2 and a threepoint connection is made to the valve so that the cathode 14 is at HF potential and the grid 15 is earthed through the signal input circuit 19. The circuit can also be used to apply the local and signal frequencies to the first detector of a superhet receiver, the signal input being between grid and earth, and the local oscillations between cathode and earth. The H.T. supply is taken from terminals 8, 9 through chokes 7, 6. The effect of the valve interelectrode capacity on the main oscillatory circuit is minimized by the screening-grid 16, and by the inclusion of small series condensers 20, 21. As applied to a superhet circuit, Fig. 3, the beat frequency is built up in a tuned anode circuit 24, 25, in series with the choke 7 which excludes the heterodyne frequency. In Fig. 4 the beat frequency is collected in a circuit 4, 26, 27 located between the cathode 14 and earth, the local heterodyne circuit consisting of the coil 2 and condensers 1, 4, 21. The condenser 20, for reducing the effect of valve capacity, is in this circuit shunted by a high resistance 28 designed to pass the necessary plate current.
