Title: Process of increasing the intravenous compatibility of gamma globulins
IPC: C07K16/06
Filed: 1977-02-07
Abstract: A precipitate, which consists of fractions which are tolerated and those which are not tolerated by the body, of gamma-globulins precipitated from blood and blood products is chemically fractionated. The entire precipitate is for this purpose taken up or dissolved in an aqueous solution which contains macromolecular substances which are capable of uniting with the fractions which are not tolerated. The resulting aqueous solution containing gamma-globulin is then additionally mixed with a suspension of micaceous sheet silicates which have cation-exchange capacity. After a reaction time sufficient for the globulin fractions which are not tolerated to bind, by cation exchange, in the sheets of the sheet silicate has elapsed, a precipitating medium is added in order to remove the gamma-globulin fraction which separates out, together with the sheet silicates. Examples of suitable sheet silicates are bentonite, batavite and vermiculite, and an example of a suitable precipitating medium is polyethylene glycol.

Title: Improvements in or relating to recording device
Filed: 1939-02-16
Abstract: 525,212. Record printing machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 16, 1939, No. 5130. Convention date, March 24, 1938. [Class 106 (iv)] A record printing machine includes type wheels bearing time and count indications, a platen moved relatively to the type wheels cyclically by electromagnetic means and means normally held in one position by the power supply to hold the circuit between the electromagnetic and cyclically operated means closed, said means being moved to an alternative position upon failure of the power supply whereby the electromagnetic means are operated upon the termination of the power failure to effect a printing operation to automatically record time of failure and the count at such time. The invention is described as a machine for counting the traffic along a road, the total passers-by being printed each hour. Counting mechanism.-Impulses which may be generated by photo-electric cells closing contacts energize magnet 69 Fig. 4, to lift the solenoid 70 to rotate the spring-pressed U-shaped member 74 which closes contacts 81 and bears spring-pressed pawls 82, 83 which rotate a ratchet 84 having fixed thereto a units type wheel 90. The tens and hundreds type wheels 91 Fig. 2, (not shown) are operated by Geneva wheels. Timing mechanism.-A synchronous motor drives a shaft 16, Fig. 3, which bears cams 17 and 18 and rotates once per minute. Cam 17 operates through lever 19 and spring-pressed pawl 27 a gear 26 having fixed thereto a minute type wheel 44. Further cams and levers operate further type wheels for hour and day records. Printing mechanism.-Cam 18 operates lever 48 to close contacts 49 at the sixtieth second of each minute for about two seconds. Cam 33 on the hour wheel 42 operates a lever 34 to turn lever 50 counter-clockwise and straighten links 51, 52. When the lever 34 drops from the high point of cam 33, lever 50 rotates the block 53 through the straightened links 51, 52 to close contacts 58, 59, once each hour at the same time that contacts 49 close, to energize magnet 93, Fig. 1, which raises a platen 98 to print the record of the type wheels on a record strip 100. When the lever 48 drops from the high-point of cam 18, contacts 49 open to de-energize magnet 93 which releases spring-influenced lever 102 to advance strip 100 and ribbon 99 through gears 126, 127 and to operate link 66 and close contacts 130. Link 66 also rotates lever 62, Fig. 3, which strikes the projection 64 of toggle 51, 52 to break the straight line previously formed and to open contacts 58, 59. In the event of current failure, a printing operation is performed immediately the current supply is resumed. A circuit is described with reference to Fig. 6, (not shown).

Filed: 1933-02-20
Abstract: 397,189. Optical-projection apparatus. ZEISS, C., [Firm of], Carl Zeiss-Strasse, Jena, Germany. Feb. 20, 1933, No. 5144. Convention date, Feb. 22, 1932. [Classes 97 (i) and 97 (ii).] In order to construct an image of the ground and plot a map from a successive series of aerial photographs, three or more image projectors are adjustably mounted on a common supporting rod, which is universally adjustable relatively to a projection surface. A number of such supporting rods, corresponding to the different lines of flight of the aircraft, may be used. In the form shown, a plane support plate 1 is adjustably mounted by means of three feet 2, 3, 4 on a base plate 5 supporting a drawing-sheet 5a. Two frames, each comprising three pillars (e.g. 6, 8) with adjustable feet and a supporting rod 14 which may be connected to the pillars at a height corresponding to the altitude of the aircraft when taking the photographs by means of transverse bores in the pillars, rest on the plate 1. The supporting rods 14 have racks 16 and knife edges 18 on which rest a number of projection chamber carriers 20 each having a pinion 22 engaging a rack 16 and enabling it to be moved along the rod 14 by a milled head 23. Each carrier 20 supports a slide 25 which may be adjusted along the axis Y-Y by a screw 27 and in turn carries a slide 29 adjustable along the axis Z-Z by a screw 30. An annular body 33, angularly adjustable in the slide 29 about an axis U-U by gearing 35, 36, carries a supporting body 37 which is angularly adjustable about an axis V-V intersecting the axis U-U at right-angles at M by means of the screw 38 engaging a lug 40 on the body 33.

Title: Semiconductor switching device
IPC: H01L27/08
Filed: 1971-02-23
Abstract: 1365392 PNPN switches MICROSYSTEMS INTERNATIONAL Ltd 30 July 1971 [23 Feb 1971] 5257/71 Heading H1K In a planar PNPN switch (e.g. as shown in Fig. 3) in which the cathode electrode 9 shunts the junction between the emitter zone 7 and adjacent base zone 6, the resistance of the conductive path from the point of contact of electrode 9 on the base zone either to a point on the centre junction periphery of lowest breakdown voltage (12 in Fig. 3) or to a conductive ring on the base zone surrounding the emitter is less than that of any other path between it and any other point on the junction periphery or the ring respectively. Typically, the Fig. 3 device is formed by epitaxially depositing an N layer on a P-type silicon substrate 4 and diffusing to form a P-type isolation region 80 extending to the substrate and to form within the isolated part 5 of the layer a P region 6, and within that an N region 7. In one embodiment the P region is formed in two stages, first by diffusing deeply through mask 3A (or 3C) and then shallowly through mask 3B (or 3D) to give the configuration of Fig. 3 and Fig. 3E respectively. N-type emitter region 7 is formed with an aperture near one edge, through which cathode electrode 9 also contacts the first base region 6 at 8. Breakdown of the centre junction commences at the curved portion 12 of its shallow part. The current path to it from contact 8 beneath the emitter is of low resistance on account of its shortness thus providing a high switching current. The resistance may be further reduced by providing a channel through the emitter from contact 8 opposite point 12, which may be of the same width as the aperture. In this case the emitter may have horn-like projections at the end of the channel. In another modification the contact is extended on the passivating oxide as a field electrode over the centre junction to raise its breakdown voltage, except in the vicinity of point 12. In addition the junction may be modified to have a serrated edge near point 12 to reduce its breakdown voltage there. In a further set of embodiments in which region 6 may be formed in a single diffusion step an equipotential ring of metal or heavily doped semi-conductor surrounds the emitter region. Switching current then flows along a shortest path from contact 8 to the ring and hence to the point of easy breakdown on the centre junction. In all embodiments the holding current is determined independently by the sheet resistance of region 6 and the distance from the equipotential ring where present or from the remotest point of the emitter to contact 8.
