Title: Aromatic copolyesters suitable for textile fibres and a process for the production thereof
Inventor: KURIYAMA SUTEZO
IPC: D01F6/62
Filed: 1957-09-16
Abstract: Fibre-forming aromatic copolyesters are made by copolymerizing (a) 3-methoxy-4-(b -hydroxyethoxy) benzoic acid or a methyl or ethyl ester thereof with (b) 4-(b -hydroxy-ethoxy) benzoic acid or a methyl or ethyl ester.  Preferably copolymerization is effected at 200-300 DEG  C. in presence of a metal oxide, a metal salt of an inorganic or organic acid or an organo-metallic compound as catalyst and the molar ratio of (a) : (b) is 8.2 to 1.9.  The properties of the copolyesters are compared with homopolymers of (a) and (b).  Fibres made from the copolyesters by melt-spinning may be drawn, advantageously in water at above 40 DEG  C., to between 3 and 7 times their original length. The hot-water resistance of the resulting yarns may be increased by heating the stretched fibre, advantageously in water, in such a way that contraction is prevented and preferably at 60-100 DEG  C. for 2-30 minutes. Specification 604,985 and U.S.A. Specification 2,686,198 are referred to.ALSO:3 - Methoxy - 4 - (b  - hydroxyethoxy) - benzoic acid is prepared by heating vanillin in sodium hydroxide solution with ethylene chlorhydrin or ethylene oxide to give 3-methoxy-4-(b -hydroxyethoxy)-benzaldehyde which is then oxidized to the acid with oxygen, sodium hypochlorite, sodium permanganate or other mild oxidizing agent.  The methyl and ethyl ester may be prepared by standard methods.  The acid or its ester is copolymerized with 4-(b -hydroxyethoxy)-benzoic acid or its methyl or ethyl ester to yield a fibre-forming copolyester (see Group IV (a)). Specification 604,985, and U.S.A. Specification 2,686,198 are referred to.

Title: Improvements in or relating to thermionic valve amplifying systems for television and like transmission systems
IPC: H04N5/16
Filed: 1935-10-23
Abstract: 464,828. Television. BAIRD TELEVISION, Ltd., and WILLANS, P. W.. Oct. 23, 1935, No. 29312. [Class 40 (iii)] Relates to television and like transmission systems by which complex signals are transmitted with suppression of the direct current component, the signals having periodic maxima or minima which would have a constant value were the D.C. component present. According to the invention, the missing component is re-inserted by means of a D.C. amplifier from the output of which is fed back a component which tends to keep the periodic maxima or minima at a constant value. The signal is transmitted over a channel 1 which suppresses the D.C. component and is fed to an amplifier 2 which amplifies all components down to zero. Across the output of the amplifier 2 is connected a rectifier 3 biassed by a source of potential 4 in series with a resistance 6 and a condenser 5 in parallel. A resistance 7 is connected in series with 5 and 6 across the input of the amplifier, which is such that the output and the input are in phase opposition. Assuming that the recurrent maxima at the input of the amplifier 2 are positive, when these have a desired value the bias on the rectifier 3 is adjusted so that current just flows, charging the condenser 5 negatively. Current passing through the rectifier tends to increase if the amplified potential at the output of 2 begins to decrease. Thus a substantially constant level of the current maxima at the output of the amplifier 2 is maintained. The amplifier 2 may be combined with a radio transmitter feeding an aerial, in which case a further rectifier is included between the rectifier 3 and the output from the amplifier 2.

[Also in Division F1] A rocket engine using solid and liquid components hypergolic with respect to each other comprises a reaction chamber into the upstream end of which a liquid component is injected and a solid component arranged to leave a passage for the flow of reaction products therethrough to the outlet nozzle of the rocket, there being in the passage at least one transverse obstacle so as to increase the time spent by the flow of the products upstream of the obstacle and thereby intensify the consumption of solid component upstream thereof. A rocket engine, Fig. 1, has a combustion chamber 1 containing solid fuel components 3a, 3b, 3c with a circular passage 4 therein. An adjustable injector 5 delivers liquid oxidizer, such as nitric acid, which is hypergolic with respect to at least component 3a.

Filed: 1954-10-12
Abstract: <PICT:0779666/III/1> <PICT:0779666/III/2> A chuck 22 (Fig. 4) is raised to lift seed germanium 21 from immersion in indium-impurity germanium melt 20 and thus draw out a bar crystal 14 of indium-impurity P type germanium.  Then in order to form N type layers 16 in the P type crystal 14 (see Fig. 3) charges of arsenic and indium are added at intervals to the melt 20 and as withdrawal proceeds the fast-diffusing arsenic produces the N type zones 16. The charges may be arsenicindium alloys with the slow-diffusing indium in the greater proportion. If desired the temperatures of the melt may be increased after the charge is added to melt back a portion of the P type zone. Crucible 17 is electrically heated and whilst the chuck 22 is being raised it may also be rotated so as to stir the melt 20. The arsenic and indium may be added to the melt as separate elements instead of in alloy form.

Title: Improvements in the production of triaryl phosphines
Inventor: LAUTENSCHLAGER HANS
IPC: C07F9/50
Filed: 1961-08-17
Abstract: Triaryl phosphines are prepared by mixing an aryl halide with activated aluminium, stirring the mixture for about 1 to 100 hours at an elevated temperature, if desired in the presence of an inert solvent, until the bulk of the aluminium is dissolved and reacting the resultant product with a halide of trivalent phosphorus at a temperature between 100 and 300 DEG C., if desired after distilling off the solvent.  The aluminium may be activated by intimately mixing with small amounts of a halogen, hydrogen halide, a metal halide, a non-metal halide or an organo-metallic compound.  The phosphorus halide may be organic or inorganic. The product, which consists essentially of a mixture of aluminium halide and a triaryl phosphine-aluminium halide adduct may be worked up by hydrolysis and extraction or by adding a complex former for the aluminium halide, e.g. an alkali metal halide, a t-amine or POCl3, and distilling. Triphenyl phosphine is prepared in examples.

Abstract: 640,668. Jettison able cockpit hoods. BLACKBURN AIRCRAFT, Ltd., HAND, P. G. E., and BULMER, N. Nov. 12, 1947, No. 30134. [Class 4] A jettisonable sliding cockpit hood of the kind in which the rails on which the hood slides swing up about a rearwardly disposed axis to effect disconnection, is provided with a spring-loaded plunger carried by a rail 4 capable of engaging an aperture or recess in the hood, the plunger being normally held retracted to permit free sliding movement of the hood on the rails but being released to engage the hood to lock it against sliding when the rails commence to swing upwardly, the latter normally being held against lateral displacement or distortion. The device is shown applied to a hood which pivots about releasable connections 5 at the rearward ends of the rails, and in which jettisoning is initiated by spring-loaded plungers 6, the rail 2 carrying amounting 8 disposed near its mid-point and which forms a housing for the plunger 7. The rail 2 engages a bracket 14 secured to the fuselage structure, lateral distortion of the rail being thus prevented. The plunger 7 is normally held retracted by a lever 11 which is engaged by a rod 15 extending between the vertical side walls of the bracket 14, but upon the initial swinging movement of the rail 2 the lever 11 is disengaged from the rod 15 and the end of the plunger 7 enters an aperture 9 in the side frame member 10 of the hood 1, thereby preventing sliding movement of the latter.
