Title: Improved process for the manufacture of deterioration retarders for rubber, and products obtained thereby
IPC: C08K11/00
Filed: 1925-05-05
Abstract: Deterioration retarders for vulcanized or unvulcanized rubber, balata, or gutta-percha are prepared by condensing equi-molecular proportions of acetaldehyde with an aromatic amine such as aniline, o-, m-, or p-toluidine, monomethylaniline, or 4-amino-1 : 3-xylene, in acid solution.  In an example an aqueous solution of aniline hydrochloride is stirred with an aqueous or acid solution of acetaldehyde at below 25 DEG  C. for half an hour and eight to nine-tenths of the acid in the resulting solution is neutralized by addition of a base such as caustic soda or aniline or other aromatic amine whereupon the condensation product is precipitated, filtered, and dried.  In the case of using aniline for precipitation the solution of the hydrochloride remaining may be made up to its original strength and condensed with a further proportion of acetaldehyde.  Reference is also made to the use of sulphuric acid as the acid.  Specifications 180,978, 220,320, and 220,321, [Class 70, India-rubber &c.], are referred to.  The Specification as open to inspection under Sect. 91 (3) (a), refers to the condensation of equimolecular proportions of aliphatic aldehydes in general with aromatic amines in acid solution.  This subject-matter does not appear in the Specification as accepted.

Title: Treatment of silicon carbide
Inventor: STELZER ISIDORE
IPC: H01L21/04
Filed: 1962-03-27
Abstract: Contacts on a silicon carbide semiconductor device are protected against etchants by being coated with a metal e.g. gold, platinum or palladium which forms a eutectic with the contact material.  In one example a P type silicon carbide crystal is provided with an ohmic contact by alloying thereto boron doped silicon; the assembly is placed on a tantalum platform in a gold cyanide electroplating bath so that both the silicon and exposed silicon carbide are coated with gold.  Alternatively, the gold may be applied by vacuum evaporation or sputtering.  A gold-silicon eutectic is formed by heating to 400-500  DEG C. at which temperature the gold on the silicon-carbide surface breaks up and does not interfere with the subsequent etching process which utilizes an etchant comprising equal parts of potassium nitrate, chlorate and carbonate heated to 600-700  DEG C.

Title: Methods and apparatus for the evaporation or concentration of liquids
IPC: B01D1/22
Filed: 1945-05-10
Abstract: <PICT:0599269/III/1> A process for concentrating liquids, such as those decomposed by excessive heating, comprising feeding the liquid in a thin film and causing internal heating of the moving film by submitting it in a closed chamber to the direct radiation of a source emitting infra red raditions and evacuating the vapours from the chamber. The liquid may be fed by gravity or capillary action or centrifugal force, and may be preheated by heat exchange with the volatiles in a preheater.  In Fig. 1, a closed heat insulated vessel 1, evacuated by a pump, or other means, 3 through a conduit 2, contains lamps 4 emitting radiations corresponding to the band of maximum absorption of liquid to be evaporated, directed on to a thin film of the liquid flowing down a tubular wall 5 of noncorrodible metal which reflects the radiation.  The liquid is introduced through an annular passage 6, between the head of tube 5 and ring 6a fitted with serrations, and located at the base of an annular chamber 7 which communicates with the interior of tube 5 by a series of openings 8, and into which liquid is delivered from a feed vessel 10 through a conduit 9.  A hydraulic guard ring is interposed between vessel 12 and sump 13.  For ensuring regulation of the concentration, vessel 12 contains a hollow float 16, connected by means of a flexible hose 17 with a recycling conduit 18-19 fitted with pump 20 and return valve 21.  In the modification shown in Fig. 2, the portions of greater diameter of a drum 31 are immersed in the liquid to be concentrated in the tank to the level z-z and, adhering by its viscosity and driven by the rotation of the drum, the liquid reaches collector 33 and cup 34.  The liquid is heated in its flow <PICT:0599269/III/2> along 32 by radiations from source 35.  The cup 34 and spring 36 device operates the flap valve 47, 48.  In a further modification the liquid is allowed to flow into the centre of a parabolic bowl rotating about a vertical axis, and is caused by the centrifugal force to flow in a thin film to the outer edge of the bowl while being heated by the radiations from lamps.

Abstract: 559,695. Casting-machines. STONE & CO., Ltd., WITTON, G. A. J., and HENDRA, A. C. Aug. 26, 1942, No. 12005. [Class 83 (i)] A turret casting-machine wherein the moulds m, Figs. 1 and 2, dwell at a number of stations I ... VI for pouring, core withdrawing, dieopening &c., has the turret-indexing mechanism driven through variable speed gearing k. This is connected to an electric motor or other prime mover and, through reducing gearing and bevel gears e to a Geneva stop mechanism f for inter-. mittently rotating the turret a. At station I a core u may be inserted in the mould; at II inert gas or air charged with sulphur or other powder may be injected; before the mould reaches III it is closed by means of fixed cam q and lever o ; at III a ladle 1, containing a charge of molten magnesium or other metal, which has been automatically delivered to it, is skimmed by a blade 17 operated by a rod 18 and cam 20, and tilted by a rod 7 and cam 9, to charge the mould ; at IV the core is wholly or partly withdrawn by a lever t and a fluidoperated plunger v controlled by a valve 22 and cam 23 ; before the mould reaches V it is closed by the cam q ; at V the operator removes the casting and the mould may be cooled by an airblast 40, and at VI the mould may be cleaned and dressed. In modifications station II may be idle or may be used for other preliminary treatment. Gas jets 41 may be used to bring the moulds to desired temperature when commencing operations. To avoid a stoppage, during the cleaning of a ladle, the pouring means are duplicated and either ladle may be brought into position by swinging the head 39 about the pillar b, the ladle not in use being removed by releasing a catch 2. To prevent the movement of the head from moving the cams 9, 20, 23, driven from a shaft 113, Figs. 1 and 3, this is driven through a differential gear 36, of which the cagc is mounted on a broad toothed wheel 38 which is in gear with a stationary gear 39 having half the diameter of the wheel 38, the gears 12, 112 having the same diameter. The head 29 can also be moved by a nut 35 to adjust the position of the ladle vertically and screw and hand-wheel 28 is used to adjust this horizontally. The metal may be subjected to a blast of inert gas or otherwise treated while in the ladle or the supply nozzle 3 may deliver, by means of a pump or a pneumatic impulse timed by a cam-operated valve 22a, a measured quantity of metal direct to the mould.
