Title: Process for separating fatty acids from glycerides
IPC: C11B3/06
Filed: 1926-02-16
Abstract: 257,170. Eisenstein, A. Feb. 16, 1926. Purifying fats and fatty oils; obtaining fatty acids by decomposing fats and fatty oils.-Fatty acids are removed from glycerides by the addition of a soap insoluble in the glycerides. The fatty acids are adsorbed by the soap, which is then removed from the glycerides, as by means of a salt solution of lower specific gravity than the soap. The separated acids contain no neutral oil. An acid oil may be neutralized by this means by adding soap thereto, or by partly saponifying the acids present and using the soap thus formed to remove the remaining acids, or by completely saponifying the acids in a portion of the oil and using the oil-bearing soap so obtained to remove the acids in a second portion of the oil, the oil in the soap then being replaced by acids. In the last event, the soap containing fatty acids may have the last traces of oil removed by centrifuging, pressing, or blowing with air &c. The method of separation can also be used for obtaining fat-free fatty acids from the products obtained by decomposing fats and oils by the autoclave or reactive processes, the decomposition being prematurely interrupted and the reaction mixture being then treated with soda lye and a salt solution, the fatty acids obtained on adding hydrochloric acid being free from neutral fat. Examples are given of the removal of acids from olive oil and palm oil, and from train oil by a series of processes, and of the production of pure fatty acids from lard.

In an arrangement in which the raster on a flying-spot cathode-ray tube 1 is directed via a semi-silvered mirror 3 and lens 4 on to a still picture 6 to generate corresponding television signals in photo-electric cells 7, 7<SP>1</SP>, the area of the picture immediately surrounding the actual area 5 being scanned is illuminated by means of a light source 8 and apertured mask 10 during intervals in the scanning, i.e. during frame flyback or during initial " setting-up " when the tube 1 is not in use. During the latter the mask may be such as to provide a dark line corresponding to the outline of the scanned area and to allow desired pictorial effects to be obtained (e.g. by variation of the position of the picture and the magnification of the optical system), a number of different masks carried by a suitable support may be arranged to be selectively positioned in the optical path. The lamp 8 may be " flashed " directly, under the control of the frame synchronizing signals associated with the scanning of tube 1 or a constant light source, interrupted periodically by a rotating or vibrating shutter operating at a sub-multiple of the frame scanning rate, may be employed. The colour of the light from lamp 8 and that produced by the tube 1 should be different.

Title: Improvements in oil-immersed electrical switch-gear
IPC: H01H33/55
Filed: 1944-03-15
Abstract: 575,396. Oil-break switches. GENERAL ELECTRIC CO., Ltd., and NUNN, C. H. March 15, 1944, No. 4807. [Class 38 (v)] In oil-immersed electrical switchgear a baffle is immersed in the oil above the contacts to collect fluid projected upwards by the arc to prevent its passing immediately through the oil to the insulators immersed in it and there depositing newly-generated carbon. Such carbon is stated to be " active " and readily attracted to surfaces of insulators with resulting deleterious action, while carbon which has had time to lose its active property does not so readily deposit. In an on-load tap-changing switch the baffle is a tube 30 fixed by a cross bar 32 to a frame 14 carrying conductors 10, 11 in bushings 12, 13, having a diameter approximately one-third of the distance between the centres of the conductors 10, 11 and extending from just above the contacts 16, 17 to shortly below the surface of the oil. Contacts 16, 17 are resiliently mounted on pivoted rockets 18, 19 moved respectively by links 29, 28 when a lever 27 is rocked by movement of an actuating rod 25 with an insulating portion 26. Connection is made to the contacts 16, 17 by flexible conducting strips 23, 24.

Filed: 1956-02-16
Abstract: 826,855. Vacuum apparatus for forcing liquids. YARDNEY INTERNATIONAL CORPORATION. Feb. 16, 1956 [March 1, 1955], No. 4912/56. Class 102(2). [Also in Group XXXVI] In the manufacture of an electric cell or battery the battery casing 1 contains an electrode assembly 2 and has a nipple 5 located near the top of the casing housing a non-return valve 6. A container 15 is connected to the nipple 5 by a conduit 12 provided with a tap 13 and sufficient electrolyte 16 is poured into the container 15. To fill the casing with electrolyte the casing is first filled with a gas, which dissolves or reacts with the electrolyte, to expel the air and the vent 4 is closed by a cap 17. The tap 13 is then opened and the electrolyte starts to flow past the non-return valve 6 due to the head of electrolyte, the level of electrolyte being above the nipple 5. As the electrolyte contacts the gas in the casing it dissolves or reacts with the gas to create a vacuum whereby the remaining electrolyte is drawn into the casing. The invention may also be applied to introducing an electrolyte into a dry-charged battery where the battery is filled with the gas and connected to a closed container of the electrolyte by a flexible pipe containing a membrane which is broken by squeezing the flexible tube as in Figs. 2 and 3 (not shown). The electrolyte may also be fed through a funnel.

Patent GB-1035373-A (GB)
Title: Thread cutting device for thread winding apparatus
IPC: B65H54/71
Filed: 1964-02-05
Abstract: A device for severing a thread when the tension in it exceeds a given value, comprises a feeler adapted to be moved by the tensioned thread to release means restraining a movable blade urged towards a stationary cutting surface.  In Fig. 5, (not shown), the blade 42 is urged clock-wise against the stationary cutter 44 by a spring 43 and accordingly urges a lever 37 to which it is pivoted anti-clockwise against a roller 38 or an arm 352 of a pivoted bell-crank of which the other arm 351 constitutes the feeler.  When the tension rises, the feeler is rocked to move the roller off the lever 37 and allow it to move so that the blade moves over the stationary cutter to sever the yarn. Means are provided to adjust the critical tension: there comprise a lever 47 beneath lever 37 urged into engagement with roller 38 by an adjustable spring.  In another form, Fig. 13, (not shown), the second arm of the feeler bell-crank is formed as a hook which engages a lever which, when the tension rises and lifts the hook, frees the lever to be engaged by a spring to close a contact to operate a solenoid.  This moves the blade to sever the thread, a pin on the blade moving the lever to a position ready to be re-engaged by the hook.  The device is combined with a thread-clearer comprising jaws defining a gap one of which is adjustable by a nut to vary the size of the gap.
