IPC: C22B26/22
Filed: 1925-10-17
Abstract: 261,528. Michel, G. Oct. 17, 1925. Dry processes of refining magnesium; alloys.- Magnesium and its alloys are purified or refined by the addition to the molten metal of calcium in the form of small particles between 5 and 50 mesh. The metal to be treated is melted with magnesium fluoride; the calcium, which may be contained in a magnesium tube, is introduced into the molten mass, and the surface of the bath may then be covered with ammonium chloride or other non-oxidizing agent.

Title: Improvements in or relating to brakes
IPC: F16D65/14
Filed: 1946-08-29
Abstract: 632,934. Internal shoe brakes. SOC. ANON. BENDIX. Aug. 29, 1946, Nos. 26034 and 26035. Convention dates, Jan. 14, 1943, and Sept. 14, 1943. [Class 103 (i)] An internal shoe brake comprises a pair of arcuate shoes, a support member having a central fixing flange disposed substantially in the median plane of the shoes, an actuator disposed between one pair of adjacent ends of the shoes and operatively engaging both shoes, and adjusting means associated with the other end of each shoe. In one form, Figs. 1 and 2, the brake shoe support comprises plates 6, 7, secured together by welding or riveting and provided with offset portions 10, 11 constituting a fork receiving the ends of the shoes 1 which are mounted on eccentric rings 14 carried by pins 3 extending through the fork, the pins being rotatable to adjust the shoes and locked after adjustment by nuts 16. The shoeactuating cylinder 12 is mounted on an offset portion of the plate 6, and a false backing-plate 32 in two parts, which forms a dust excluder, is supported from this plate. In a second form, Fig. 3, each shoe is formed with two webs 38, 39, and its lower end is mounted on eccentric rings 44, 45 carried by a pin 36 or 37 extending through reinforcing plates 49, 50 and a sleeve 41 secured to a central brake support 40, the shoe-actuating cylinder 42 being formed with lugs 43 for attachment to the support. A false backing-plate 60 is secured to a post 61 carried by the plate 50, and posts 62 carried by the lugs 43. Figs. 5 and 6 show a further form in which floating shoes 102, 104 are expanded by a hydraulic cylinder 106, and one shoe applies the other through an adjustable connection 108. The anchoring torque is taken by a central member comprising a plate 178 reinforced by a second plate 180 having an offset portion 184 carrying the cylinder 106 and a second offset portion formed with an elongated opening 186 through which extends a handle by which the connection 108. may be adjusted from outside the drum. The shoes anchor on adjustable stops formed by eccentric rings 200 carried by pins 188 extending through the plates 178, 180 and elongated holes 190 in the shoe webs, the pins being locked after adjustment by nuts and, if desired, by friction inserts. In a modification, Figs. 8 and 9, the shoes anchor on a sleeve 230 mounted on an anchor-pin 198 extending through offset portions of plates 178, 180 constituting the central supporting member, and are applied by a cam 236 mounted on the pin 198 and formed integrally with a forked lever 238 operated by a control cable 240 in a sheath 242 welded to the supporting member. A false backing plate 246 is secured to lugs 244 on the supporting member. The shoes are positioned laterally by arms 250, 254 formed on the plate 180, and are held in contact with the arms 250 by torsion springs 252.

Title: Improved manufacture of manures
IPC: C05B9/00
Filed: 1923-10-18
Abstract: Alkali metal compounds, obtaining from complex silicates Phosphatic manures are made by heating to a sintering or fusion temperature phosphate rock with a considerable proportion of potassium-magnesium carbonate and a silicate material such as phonolite, leucite or feldspar.  Other substances such as soda may also be added.  The potash in the silicate is thus rendered soluble.ALSO:Phosphatic manures are made by heating to sintering or fusion temperature phosphate rock, with a considerable proportion of potassium-magnesium carbonate, and, if desired, a silicate material such as phonolite, leucite, or feldspar, but the silicate material is not necessary if the phosphate contains enough silica; other substances such as soda may also be added.  The potash in the silicate is thus rendered soluble as well as the phosphate.

Abstract: 1,197,403. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 31 May, 1968 [15 June, 1967], No. 26082/68. Heading H1K. In a monolithic semi-conductor structure comprising a P-type substrate 10 in which is formed an N+type region 18 and there is an epitaxial N-type layer 20 formed over the substrate and the N + type region, and wherein isolating P+type walls 26 extend through the layer to the substrate to electrically isolate areas of the layer, a P + type region 28 extends right through the layer 20 to the N + type region 18 to form the emitter of a first transistor, the adjacent portion of the layer 20 forming the base region of the transistor. A P-type region 38 forms the collector of this first transistor. In a second isolated area a complementary transistor is formed having a P-type base 40 and N+type emitter region 48. A passivating silicon oxide layer 22 covers the surface of the structure and electrodes of aluminium or molybdenum 50, 52, 54 and 56, 58, 60 provide the electrical connections and interconnections. The structure is made of silicon and the dopants used are boron, arsenic and phosphorus. A combined complementary pair of transistors is described, Fig. 4, not shown, where a PNP and NPN transistor are formed in a single isolated region. In alternative configurations of the PNP transistor, Fig. 2, not shown, the P+ type collector extends right through the epitaxial layer into the N+type region in the same way as the emitter to give a symmetrical device. Alternatively, Fig. 3, not shown, one of the P+type isolating walls may be used as the collector.

Title: Semiconductive glass
IPC: C03C4/00
Filed: 1963-07-02
Abstract: An electronically conducting semi-conductive glass composition consists essentially of (a) B2O3; (b) CaO, BaO, MgO or SrO; (c) a multivalent metal oxide present in at least two valence states. There are 20-40 mole per cent (b) based on (a) + (b), and at least 15 mole (c) based on the final glass composition.  The ratio of the number of metal ions of higher valence to those of lower valence in (c) is from 9: 1 to 1: 9. The room temperature electrical resistivity is 104-1018 ohm-cm.  The glass is produced by mixing finely-divided boric acid, the oxide, carbonate oxalate, nitrate, or other compound of the alkaline earth metal, and the multivalent metal oxide(s), heating to cause reaction, and partially converting the multivalent metal to a different valence state, e.g. by contact with a reducing or oxidizing atmosphere at elevated temperatures.  A membrane-like disc 10 (Figs. 1 and 2, not shown) of the glass may be formed, e.g. by blowing a glass bubble, taking a small portion when solid, reheating and refining to final thickness, and cutting or trimming. This may be sealed to iron ring 12 and used as a target in an image orthicon tube.  The glass may be coated on glass and used in television picture tubes for field potential control.  They may also be used as or in thermistors, resistors, or thermoelectrics.
