Abstract: 1345569 Preparation for diagnosing rheumatoid arthritis TAKEDA YAKUHIN KOGYO KK 19 April 1971 [16 April 1970] 26901/71 Heading B1X [Also in Division A5] A preparation for diagnosing rheumatoid arthritis comprises a minor amount by volume of human group O red cells sensitized with anti-human haemoglobin antiserum and a major amount by volume of an isotonic solution. The antiserum may be from rabbit, goat, guinea pig, sheep, horse, chicken and is preferably from an animal pretested for absence of agglutinin to human red cells by mixing a sample of its serum with, a 2% suspension of each of human A, B and O cells and rejecting those whose sera give agglutination. The isotonic solution may be physiological saline, optionally containing glycerol or glutamate as stabilizers, and preferably contains from 0.5% to 3% by volume of the sensitized red cells. In preparing the antiserum, the animal may be injected with a mixture of haemoglobin and "alumina cream" (see Division A5).

Abstract: 1,272,295. Shearing device. DR-ING RUDOLF HELL. 28 May, 1969 [4 June, 1968], No. 27110/69. Heading B4B. A device for shearing off varying lengths, e.g. from :a web 5 of photographic material comprises a fixed blade 6 and a movable blade 2 of helical form mounted on a bar 1, rotatable in bearings 3, 4 and normally held in a position of blade disengagement, Fig. 1, by a spring 7, means 9, 12, 14 being provided temporarily to couple the bar 1 to a rotating disc 10 to perform a cutting stroke. The blade disengagement position is defined by impingement of a fin 18 rigid with the bar 1 against a stop 19, and to initiate a cutting action, a solenoid 14 is actuated moving a lever 9 inwardly against the tension of a spring 11. The lever is thus engaged by a follower 12 on the disc 10, causing the bar 1 to rotate, and the blades 2, 6.to co-operate, until the follower 12 disengages and the springs 7, 11 return the blade 2 and lever 9. A switch 15, triggered by a magnet 16 on the disc 10, ensures actuation of the solenoid 14 only when the follower 12 is in the upper half of its cycle. Control, Fig. 2 (not shown).-Cutting is initiated by pressing a control-key (20) or by means of a computer signal thus actuating a monostable tripping circuit (21), and operating a relay (22) so that when the switch 15 is triggered, a -second -monostable -tripping -circuit (23) receives a tripping pulse, and the solenoid 14 is energized. A further circuit, Fig. 3 (not shown), actuates an alarm signal, e:g. a lamp 39, or interrupts operation, in the event of an incomplete cutting stroke, this circuit being governed by the movement of the fin 18.

Abstract: 1,094,693. Field-effect transistor. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 28, 1965 [July 8, 1964], No. 27238/65. Heading H1K. A single crystal insulated-gate field-effect transistor is made by applying a layer of semiconductor material of one conductivity type to a substrate, applying a mask to the layer with an opening to define a gate region and diffusing an impurity through the opening to form a diffused gate region of opposite conductivity type intermediate source and drain regions. Three insulated-gate field-effect transistors are formed on a P-type Si substrate 1 by epitaxial growth of a N-Si layer 2 containing P or As, the substrate being polished with a mixture of HNO 3 , HF and CH 3 CO 2 H. An oxide layer is formed thereon and subsequently a photoresist pattern (4, Figs. 4 and 5, not shown), through which the oxide film is removed with HF/NH 4 F. After removal of the resist pattern, boron is diffused into the epitaxial layer 2, giving gate regions 9 of P-type conductivity, together with the source 7 and drain 8. A further oxide layer 3a and a photo-resist pattern (4a, Figs. 9 and 10, not shown), are formed on the device and the oxide layer 3a etched to expose the source and the drain regions 7 and 8 respectively. A layer of A1 10 is evaporated on to the device to make contact with the source and the drain regions, this layer 10 being divided up into various electrodes by etching with NaOH through another photo-resist pattern (4b, Fig. 13, not shown), thus giving the finished device as shown in Fig. 14. In an alternative embodiment, a P-type epitaxial layer containing B is built up on a N-type substrate whilst the gate region is formed by diffusing in P. The breakdown voltage, G M  and doping concentrations are specified.

Filed: 1937-03-25
Abstract: Mixtures of alcohols and ketones are manufactured by treating alkylene oxides, preferably in the vapour phase under atmospheric pressure, with hydrogen in the presence of a hydrogenation catalyst at about 70-90 DEG  C.  The proportion of ketones in the products may be increased by increasing the rate at which the alkylene oxide and hydrogen are passed over the catalyst. Suitable catalysts are reduced metal catalysts, e.g. reduced nickel, copper or cobalt, alone or mixed with each other and associated or not with carriers or activators.  In examples: (1) a mixture of butylene oxides corresponding to a mixture of butene-1 and -2 is passed with hydrogen over finely divided reduced nickel on kieselguhr at 70-90 DEG  C., yielding methyl ethyl ketone and primary and secondary butyl alcohols; reference is also made to the hydrogenation of symm. and asymm. butylene oxides separately; (2) propylene oxide is passed with hydrogen over finely divided reduced nickel at 70 DEG  C. to produce n- and isopropyl alcohols and acetone.
