Abstract: 1,271,292. Growing whiskers from gaseous phase. J. P. GLASS. 1 April, 1969, No. 28795/ 71. Divided out of 1,271,291. Heading B1F. [Also in Division C1] Whiskers, of e.g. graphite, boron, aluminium oxide, and sapphire, are grown by crystallisation from the vapour phase by spraying ingredients of a whisker forming vapour and particulate nuclei into a turbulent mixer zone 116 within a mixing chamber 112, thoroughly mixing these ingredients and then passing the mixture downwardly into a vertical duct 113, whilst heating, e.g. by heating coil 115, said duct so as to maintain a temp. gradient and form a precipitation zone within the duct, the temperature being hotter at the top and cooler at the bottom of the duct, thereby cause whiskers to form and grow in the precipitation zone and pass downwardly therefrom into a collecting zone 138 situated below the duct. The particulate nuclei may be such as emit electrons when thermally excited e.g. BaO, SiO, CaO or the corresponding carbonates. The formation of whiskers may also be assisted by the introduction of electrons from gun 137, or a discharge from point electrode 143.

Abstract: 792,136. Pipe couplings. LAMBERT, G. J. W. Sept. 24, 1956 [Oct. 12, 1955], No. 29035/55. Class 99(1). A coupling for two elements such as pipes comprises two coaxially-disposed members respectively associated with the elements, one of the members being engaged within the other member, a conical seating on one of the members, means for relatively moving the members, and a resilient jointing member including a ring-like part adapted to engage the conical seating. Axial movement of the members towards one another causes a rolling and compressing action to be imparted to the jointing member which is forced against one of the pipes. As shown in Fig. 1, a ferrule 1, for insertion into the end of a pipe, has a flange 3 formed with a conical seating 4 and a shoulder 5 which is contacted by a sleeve 13 screwed into a collar 6 provided with a conical seating 8. By screwing the sleeve into the collar the seatings are moved towards one another so that the rubber sealing rings 9, 10 roll upon the faces of the seatings and are forced into contact with a tubular member inserted into the collar. In modifications, (a) the ferrule has a laterally-disposed spigot for connection to a pipe and is enclosed in an extension of the sleeve 13 which carries a screwthreaded, manually-operable member that moves the seatings toward each other, (b) a sleeve 24, Fig. 3, is screwed into a collar 23 and a ring 28 having a conical seating is engaged by the sleeve and interposed between the latter and the adjacent sealing ring 30, (c) one of the sealing rings is triangular in cross-section, (d) the rings 9, 10 bear on the sides of a rubber member 35, Fig. 5, which is squeezed by the rolling action of the rings so that the material of the member is forced outwardly in the direction of the arrows 36 and into sealing contact with a surface 38 ; alternatively, the member has splayed-out inner and outer peripheral portions, and (e) the sealing member co-operating with the conical seatings has a substantially flat or slightly curved inner circumference connected with spaced-apart, curved upstanding parts.

Heading G3R. [Also in Division H2]  In an electrical precipitator, a voltage decrease caused by flash-overs between the electrodes is used to determine the variation in voltage which is needed either to increase or decrease that applied across the electrodes to ensure optimum operating conditions. As shown, an electrical precipitator 12 is supplied from an A.C. source R, S by way of a contactor 2<SP>1</SP>, a magnetic amplifier 15, a transformer 10 and a rectifier 11. Voltage and current variations in the precipitator are detected by transformers 36 and 3 connected to a circuit V the output from which moves an aluminium plate F, the arrangement being such that the output from an oscillator circuit 5 including transistors T1, T2 and reactance coils LB, LK associated with the plate F, is proportional to the voltage decrease caused by flash-overs. The output from circuit 5 is applied as a charging current to an integrating circuit, constituted by capacitors K1, K4 and resistor R1, which is simultaneously discharged at a rate determined by adjustment of K4 and R1. Any output from the integrator circuit at lines 8 and 9 is applied over magnetic amplifiers 13 and 14 to the magnetic amplifier 15 the output winding of which applies the necessary increase or decrease in operating voltage to the transformer 10, until the charging and discharging of the integrator circuit reaches equilibrium.

[Also in Divisions H1 and H3] Anti-backlash screw-and-nut gearing for a radio tuner (see Division H3) comprises a rod 50 carrying a spiral groove 75 of rectangular profile co-operating with two nuts 77, 78, urged apart by a metal bellows 79. The nut 77 is screwed into a plate 70 which is thereby moved axially when the rod 50 is rotated. Each nut has a radial through-bore 80 in one side of which is inserted a pin 81. The inner ends of these pins are tapered and carry the inner members 82a of ball-races. The spring bellows 79 therefore urges the outer members 82b of the ball-races into contact with the threads 75 to prevent any axial movement of the nuts without rotation of the rod 50. In a modification (Fig. 11, not shown), the pins are smaller than the bores and ball-races are provided between the pins and the nuts 77. The inner ends of the pins are in this case wider than the outer parts, to be a loose fit in the spiral thread on the nut 50.

Title: Improvements in or relating to the production of methylolurea in solution or crystalline form
IPC: C07C275/10
Filed: 1936-11-02
Abstract: Mono- and di-methylolurea, or mixtures thereof, are prepared in solution or in crystalline form by condensing urea and formaldehyde in the presence of a sufficient quantity of an ethanolamine to make a neutral or alkaline solution, preferably at normal temperature.  In example (1) a solution containing formaldehyde, urea and triethanolamine is allowed to stand for about 12 hours; on concentrating in vacuo at normal temperature, dimethylolurea is obtained or if the solution be diluted to make a 20 per cent dimethylolurea solution it remains stable for weeks; (2) monoethanolamine replaces the triethanolamine of example (1). Diethanolamine or technical ethanolamine may also be used. Solutions of methylolurea prepared with monoethanolamine are capable of further condensation on heating without the addition of acidic substances, a property which is made use of in textile treatment.  The other solutions produced may also be used in the treatment of textiles.
