Title: Improvements in the coating of surfaces with plastic compositions
IPC: B29C48/15
Filed: 1940-10-23
Abstract: 544,713. Cellulose derivative compositions ; moulding etc.; electric conductors. DU PONT DE NEMOURS & CO., E. 1., and PAYNE, D. D. Oct. 23, 1940, No. 15582. [Class 2 (ii)] [Also in. Groups V and XXXVI] Electrical conductors and other articles are coated with a thermo-plastic composition comprising a cellulose ether and a reaction product of an aldehyde or ketone with a hydrolysed polymerized vinyl ester, by heating the composition and extruding it in a plastic state on to the surface of the conductor or other article to be coated. Preferably, a plasticizer is included in the composition. In an example, a composition comprising ethyl cellulose, 'polyvinyl acetatebutyral resin, tricresyl phosphate, and pigment is heated to 100C. and then introduced into the cylinder 1 which is heated by hot oil, diphenyl, or other fluid passing through jacket 2. The plastic composition is forwarded by the screw 3 towards wall 13 where it is deflected and passed through screen 7. A wire 9 is passed rapidly through the extrusion head and is coated with the plastic composition. The composition is further heated by introducing hot fluid at inlets 5 and 6. The coated wire is rapidly cooled on leaving the extrusion head. The synthetic resin may be obtained by using formaldehyde, acetaldehyde, propionaldehyde, isobutyraldehyde, butyraldehyde, acetone, methylethyl ketone, benzaldehyde, or furfural. The polyvinyl ester may be partially or completely hydrolysed before reaction with the aldehyde or ketone. The cellulose ether may be ethyl, propyl, or benzyl cellulose. The plasticizer may be triphenyl or tricresyl phosphate or a phthalate of a higher aliphatic alcohol, chlorinated diphenyl, or dibutyl phthalate. The temperature of extrusion may be 200-275C. for ethyl cellulose compositions. The coatings have good abrasion resistance, flexibility, toughness, and electrical insulating properties, and they adhere well to the wires or other articles. The ethyl cellulose composition may be applied to bare wire or to wire already coated with rubber, yarn, paper or other material. Specification 410,770 is referred to.

Title: Tetracycline derivatives
Inventor: CHENEY LEE CANNON
IPC: C07D211/60
Filed: 1957-05-17
Abstract: The invention relates to antibacterial substances of general formula <FORM:0809585/IV (b)/1> wherein <FORM:0809585/IV (b)/2> represents a tetracycline chlortetracycline or oxytetracycline radical and B represents a secondary amino group, and the acid addition salts thereof.  The compounds are prepared by reacting 1 mol. of the tetracycline with 1 mol. of the secondary amine and at least 1 mol. of formaldehyde or a polymer thereof in absolute alcohol.  The materials are refluxed on a steam bath in an atmosphere of nitrogen. The product is recovered by lyophilization or by precipitation by means of a non-solvent such as ether or a petroleum hydrocarbon.  The reaction may take place in the presence of t-butanol in place of the ethanol.  The free base may be converted to a salt with an inorganic or organic acid by adding the acid to the base.  Addition of alkali, e.g. sodium hydroxide, to the acid addition salt produces the base. Specified salts are those prepared from hydrochloric, sulphuric, sulphamic, tartaric, hydrobromic, hydriodic, glycolic, citric, maleic, phosphoric, succinic and acetic acids.  Examples describe the preparation of (a) N-(4-morpholinylmethyl) tetracycline; (b) N-dimethylaminomethyltetracycline; (c) N - dibenzylaminomethyltetracycline; (d) N - (1 - piperidyl-methyl) tetracycline; (e) N-(1-pyrrolidylmethyl) tetracycline; (f) N - (4 - morpholinylmethyl) oxytetracycline; (g) N-dimethylaminomethyl oxytetracycline; (h) N - dibenzylaminomethyl - oxytetracycline; (i) N - (1 - piperidylmethyl) oxytetracycline; (j) N - (1 - pyrrolidylmethyl) oxytetracycline; (k) N-(4-morpholinylmethyl) chlortetracycline; (l) N - dimethylaminomethyl - chlortetracycline; (m) N-dibenzylaminomethyl-chlortetracycline; (n) N-(1-piperidylmethyl) chlortetracycline; and (o) N - (1 - pyrrolidylmethyl) chlortetracycline.

Patent GB-796344-A (GB)
Title: Improvements relating to the manufacture of cellulose acetate crimped fibres
Inventor: FINLAYSON DONALD
IPC: D02G1/12
Filed: 1955-06-02
Abstract: Crimped cellulose triacetate filaments are given an increased degree of crystallinity by subjecting them to the action of dry heat, wet steam, hot water or an organic liquid which is a swelling agent for cellulose triacetate.  The treatment may be given during and/or after the crimping operation and may be termed "setting."  The filaments may be in the form of a tow of 5000-20,000 or more denier and the crimp may be imparted by the stuffing-box method.  The whole or part of the setting operation may be carried out on the tow while it is still in the stuffing-box.  The filaments may also be crimped by passing the tow between toothed wheels or rollers slightly spaced apart.  The preferred method of setting the crimp is by means of wet steam or hot water at 120-145 DEG  C. or up to about 160 DEG  C., for example, for 3-8 minutes at 120-130 DEG  C. or 20-60 seconds at 140-145 DEG  C. When the setting is effected with dry heat, the temperature used may be 180-250 DEG  C., preferably 200-230 DEG  C., and the treating time may be 0.5-3 minutes, the heating medium being hot air or other gas.  The setting may also be effected with a liquid organic swelling agent under the conditions set out in Specification 776,346.  In a modification, in which the crystallinity of the cellulose triacetate is not as a rule significantly increased, the crimp retentivity of the crimped tow is increased by treating the tow with hot water or wet steam below 120 DEG  C., particularly 90-120 DEG  C.  The treatment time may then be 15-40 minutes.  In an example, a 10,000 denier tow of cellulose triacetate, made by melt-spinning, as described in Specification 748,772 and having a filament denier of about 3, is crimped by the stuffing-box technique to form 14-16 crimps per inch of filament.  Portions of the crimped tow are then treated with wet steam at temperatures and for times ranging from 30 minutes at 100 DEG  C. to 30 seconds at 142 DEG  C. A method of determining the crimp retentivity of the treated filaments is described.  Specification 758,442 also is referred to.

Abstract: 181,960. Walker, J. W., and Platt Bros. & Co., Ltd. June 9, 1921. Feeding carding-engines &c.-The weighing-apparatus of an automatic hopper feeder is driven from the feed lattice of the carding-engine or other machine being supplied with fibre through a clutch arrangement, so that the movement of the feed lattice can be reversed without any disengagement of parts connected with the automatic feeder, whilst when normal motion of the feed lattice is resumed the driving of the weighing-apparatus also is automatically resumed. The weighing-apparatus w is controlled by a cam on a sleeve w<1> driven through a free wheel clutch B by a chain c irom a sprocket d which derives its motion trom the lower feed roller shaft e. The clutch comprises an outer cover b<1> and an inner half b<3> on the sleeve carrying a spring controlled tooth b<4>. If the fibre on the lattice a chokes the feed' rollers, the side shaft f can be disengaged to stop the feed rollers and the lattice a can be reversed by hand. The clutch B then runs freelv and the weighing-apparatus is not operated. When the lattice a is restarted in the normal direction the clutch B immediately takes up the drive.
