Abstract: 1440567 Chloroprene from 3,4-dichlorobutene-1 BP CHEMICALS INTERNATIONAL Ltd 28 Sept 1973 [26 Oct 1972] 49350/72 Heading C2C Chloroprene is produced by the dehydrochlorination of 3,4-dichlorobutene-1 in a substantially non-aqueous environment by contact with a metal alkoxide wherein the alcohol moiety has at least 3C atoms. The alkoxide is preferably derived from a C 3-20  alcohol such as iso-propanol n-, sec- or tert-butanol and contains an alkali metal selected from Na and K. It is advantageous to use the alkoxide in an inert solvent such as the corresponding alcohol and in the presence of a polymerization inhibitor such as phenothiazine, dihydric phenols and nitroso-compounds. An inert atmosphere is preferably employed and the process carried out in a continuous manner by distilling off the chloroprene formed directly from the reaction vessel.

Abstract: Shaped lithium fluoride articles are prepared by compressing lithium fluoride powder at a temperature of 400-550 DEG  C. and a pressure of 5000-10,000 atmospheres.  The powder should preferably be dried before compression.  In the examples, lithium fluoride was precipitated from lithium carbonate with hydrofluoric acid and the precipitate was filtered off and dried at 150 DEG  C. for 20 minutes and then at 750 DEG  C. for one hour.  The powder was then compressed at 500 DEG  C. and 8000 atmospheres for 5-10 minutes.

Abstract: 1,130,452. Developing electrostatic images. RANK XEROX Ltd. Dec.9, 1965 [Dec.28, 1964], No. 52192/65. Heading G2H. A method of developing an electrostatic latent image by bringing the member carrying the image into contact with a fluid dispersion of toner particles is characterized by agitating a mixture of toner particles and carrier particles in a region adjacent the member while applying an electric field, distinct from the image field, to the mixture, thereby separating the toner particles from the carrier particles and causing movement of separated toner particles from the mixture towards the image bearing member. As shown, a grid 13, Fig. 3, is placed adjacent a xerographic plate 10. A conductive shoot 18 conveys and agitates developer 14 poured from a container 16. A potential 15, of the same polarity as the toner particles is applied to the shoot causing toner particles to be separated from carrier particles due to the field between the shoot 18 and screen 13; the separated toner particles form a cloud. Large carrier particles are prevented by screen 13 from entering the image field. By applying a bias to screen 13 e. g., 10 to 130 volts, back ground deposits of toner on the plate 10 are reduced. The toner particles may be dispersed in air, carbon dioxide, nitrogen, or hydrocarbons such as kerosene or trichloro trifluor and ethane.
