Patent GB-727923-A (GB)
Title: Preparation of alkali metal alcoholates
Filed: 1952-11-17
Abstract: Alkali metal alcoholates suspended in an inert liquid hydrocarbon are obtained by reacting an alkali metal in the form of dispersed particles, having an average size not greater than 100 microns and suspended in an inert hydrocarbon medium with an alcohol.  Suitable hydrocarbons are, for example, toluene, xylene, petroleum fractions, straight-run gasoline, kerosene, alkylate, mineral oil, octane, undecane, nonane and substituted naphthalenes.  If desired, the alcohol may be premixed with an inert liquid hydrocarbon which may be the same as or different from the hydrocarbon in which the alkali metal is suspended.  A dispersing agent may be added to the dispersion of alkali metal. Suitable dispersing agents are fatty acids, activated carbon or clay, and charcoal.  The process is suitable for the preparation of alcoholates of alcohols such as methyl, ethyl, propyl, isopropyl, n-butyl, sec.-butyl, tert.-butyl, amyl, hexyl, octyl, decyl, benzyl and xylyl alcohols as well as higher alcohols such as lauryl alcohol, tridecanol, myristyl alcohol, cetyl alcohol, stearyl alcohol, eicosanol and docosanol.  It can also be used for forming the alcoholates of unsaturated alcohols such as oleyl, linoleyl, palmitoleyl and eleostearyl alcohols, phytol and ricinoleyl alcohol and of alcohols derived from naturally occurring fats and oils such as sugar cane oil, menhaden oil, cotton seed oil, peanut oil, olive oil, soya oil, tung oil and palm oil.  In the examples (a) metallic sodium is dispersed in toluene and treated with ethyl alcohol to give sodium ethylate; (b) metallic sodium is dispersed in toluene and treated with a mixture of alcohols obtained from menhaden oil.

Abstract: 336,763. Dassonville, M. Feb. 19, 1929, [Convention date]. Spindle apparatus; reeling- machines.-Means for collecting artificial wool as it is delivered from a spinning-machine, such as described in Specification 263,727, [Class 120 (iii), Yarns &c.], comprises a pair of containers, either of which can be brought into position to receive the staple, the containers revolving on a vertical axis at such a speed that no tension is exerted on the staple. A reciprocating movement is imparted to the container, or to the delivery drum of the machine, or to the material as it leaves the drum, so that the material is deposited in the form of hanks with crossed or imbricated layers, as shown in Fig. 5, which after the usual washing, bleaching and dyeing may be reeled, cut into lengths, or after being twisted can be used directly for spinning and weaving. In the arrangement shown in Fig. 1, a carriage 1 supported on rollers 3 carries a casing 5 in which baskets 6, 7 for the reception of the material are rotated by bevel gears 11, 12 on a socket 13 splined on a driving-shaft 14, and adjustable crank-pins 22 driven by a gear 16 on the shaft 14 are connected to a transverse member 18 of the carriage to impart the necessary reciprocation to the baskets. The carriage is connected to the transverse member 18 by a screw operated by a hand-wheel 28 whereby, when one basket is full, the carriage may be moved to bring the other into operative position. The crankpins are adjusted to give any desired reciprocation which may be reduced to zero, concentric layers then being deposited and the basket slowly moved to fill it uniformly. The baskets are shallow and are provided with a rectangular section annular groove to receive the material. In the arrangement shown in Fig. 7, the frame 35 carrying the drum 33 which draws the material from the coagulating bath is oscillated by a cam 40. The drum 33 may be stationary and the material reciprocated after it is detached therefrom.

Title: Decoding system for a television receiver

Filed: 1971-06-22
Abstract: 1337654 Colour television SONY CORP 22 June 1971 [17 Nov 1970] 29311/71 Heading H4F A decoder for PAL colour television signals utilizes only every second line of chrominance information by use of a one line delay line 2 and switch 4 operated at the end of each line period. As a result the signals fed to the demodulators 7 and 8 have the same modulation axes for all lines. The sub-carrier frequency reference signal for the B-Y demodulator 8 is derived by averaging the burst phases in the incoming signals to give a signal of -(B-Y) phase which is inverted at 23, and the R-Y reference signal is derived by use of an inverter 9 and a second switch 11 to produce a signal whose phase is the average of the burst phase in one line and the inverse of the burst phase of the succeeding line, which will be in phase with the R-Y modulation axis of the signal passed by switch 4. Hue controls 18 and 24 are provided and may be ganged together. In an alternative embodiment the non-inverted input to switch 11 is provided from the output of switch 4. The delay 2 may be provided after switch 4, the switch passing every second line and each demodulator being connected to the switch output directly and via the delay line. Alternatively switch 4 may be replaced by a diode switch (25, Fig. 8, not shown) which has two outputs, one producing chrominance signals with positive B-Y and R-Y modulation axes and the other signals having positive B-Y and negative R-Y modulation axes. The inputs to switch 11 may then be provided from these outputs, demodulators 7 and 8 being fed with signals from one of the outputs. The B-Y reference signals may also be derived from these outputs by using a further switch. Alternatively each demodulator may receive signals from a different one of these outputs or the B-Y demodulator may receive signals from the input which have by-passed the switch 4 (or 25).

Title: Method of producing cryolite
IPC: C01F7/54
Filed: 1954-10-13
Abstract: Cryolite is obtained by leaching calcium fluoride sintered with quartz sand and soda, with a soda solution containing sodium aluminate (e.g. taken directly from a Bayer process) precipitating cryolite with carbon dioxide, converting the so-formed bicarbonate liquor into soda with lime and/or caustic soda and leaching further quantities of sinter with the resulting solution.  After a number of leaching stages the causticized liquor (which may contain up to 120 grams soda/litre) may be causticized to form sodium hydroxide with lime and used to make up losses in a Bayer process.  In a preferred modification, the sinter is leached with a soda-aluminate solution containing 70 to 80 grams of Na2CO3 per litre.  After precipitation of cryolite two-thirds of the mother liquor is causticized, half of the causticized lye is mixed with the remaining mother liquor and an equivalent amount of water, and the resulting lye is recycled. In the examples a sinter obtained at 780 DEG C. to 820 DEG . was used and leaching performed at 50 DEG C. and 30 DEG C. to 100 DEG C. respectively.
