Abstract: 721,799. Dynamo-electric machines. GENERAL ELECTRIC CO. Jan. 2, 1953 [Jan. 5, 1952], No. 163/53. Class 35. [Also in Group XXIV] The salient-pole rotor 13 of an alternator and the armature 14 of its exciter are mounted on an outer hollow shaft 25 of differing diameters which is splined at the driving end with an inner concentric torsional shaft 24. One end of the inner shaft 24 carries a gear wheel 27 to be driven by a prime-mover (not shown), while the other end has splines 26 by which connection is made to the outer shaft 25. Both the exciter commutator 19 and slip rings 37, 38 are mounted on that part of the outer shaft having a diameter D 2  which is smaller than the diameter D 1  of that part of the shaft carrying both rotor cores. The two leads from the rotor field coils 16 to the slip rings 37, 38 comprise conductors 45 in sleeves 46, 47 which may be of glass or treated glass cloth. These leads are located in the space between the two shafts. In a modification, the outer shaft 25 is made shorter by replacing the shortened piece by a hollow stub shaft 51 bolted to the shaft 25. A flange portion 52 provides a journal bearing surface for the inner shaft 24. These two members may be separated by turns of asbestos cord 53 to act as a flexural vibration damper between the inner shaft and its supporting member.

Title: Improvements in or relating to process of preparing ethylene oxide and its homologues
Filed: 1938-01-06
Abstract: <PICT:0495676/IV/1> In the production of olefine oxides by the hydrolysis of chlorhydrins with alkalies or alkaline earths, the mixture is boiled under reduced pressure in at least two stages which are carried out in separate apparatus in series.  In the apparatus shown, the chlorhydrin solution from a pipe 1 is led through a heat-exchanger 2 to the first hydrolyzer 4, milk of lime being admitted by a pipe 5.  The hydrolyzer 4 is connected by a pipe 7 with the second hydrolyzer 6.  Each hydrolyzer is provided with a cooler 12.

Abstract: 391,735. Collecting latex. VIS, D. M., 96, Benoordenhoutscheweg, The Hague. Jan. 6, 1933, Nos. 500 and 501. Convention dates, March 3, 1932 and Nov. 28, 1932. [Class 70.] Coagulation of latex and like soaps in the tapping cut is prevented by inserting an anticoagulant body g into or adjacent to the uppermost point of the tapping cut b-c. The shape of the anticoagulant material is preferably that of a pin. Instead of pure anticoagulant, a neutral material such as wood, sugar cane, kaolin, charcoal, bamboo, cotton thread, or agar-agar may be impregnated with the anti-coagulant. The preferred neutral material is sugar cane. Suitable anti-coagulants are formalin, caustic soda, or sodium carbonate. When using a volatile material like formalin, the neutral material is held in the vapour until impregnated. It is stated that an increased yield of latex is obtained by the process according to the present invention.

Title: Method of semi-continuous and continuous dyeing of fabrics
IPC: D06B3/10
Filed: 1962-01-06
Abstract: Continuous and semi-continuous methods of dyeing fabrics comprise treating the fabric, after passage through a dye-bath, in a pad mangle, which may be of known construction, followed by a second mangle having rollers mounted in the horizontal plane sealed at the ends and holding a small quantity of developing liquor.

Patent GB-853596-A (GB)
Title: Improvements in the production of unsaturated gaseous hydrocarbons and of synthesis gas
IPC: C01B3/38
Filed: 1958-01-08
Abstract: Unsaturated gaseous hydrocarbons especially ethylene, and synthesis gas are produced by cracking hydrocarbon oils at high temperatures, e.g. between 600 DEG  C. and 900 DEG  C., in a fluidised bed with oxygen, with or without the addition of endothermically reacting media such as steam or carbon dioxide, returning the products having a higher boiling point than gasoline to the cracking process and reacting the products of low boiling point and/or the gaseous cracked products which have been partly or wholly freed from unsaturated hydrocarbons, with oxygen at temperatures above 700 DEG  C. to form synthesis gas.  In an example a mineral oil distillation residue boiling above 350 DEG  C. is sprayed by means of superheated steam into a reaction chamber containing a bed of oil coke which is fluidised by superheated steam and oxygen and is at a temperature of 700 DEG  C.  The product gases and vapours have most of the coke dust removed and this may be returned to the process or burnt to obtain heat.  The gases and vapours are then washed with an oil originating from the process and the products boiling above 250 DEG  C. are returned to the process, there being 0,5 kilograms per kilogram of fresh oil.  The low boiling hydrocarbons are separated from the gases, vapourized and introduced with steam and oxygen into a gas producer operated with coke at such a temperature that liquid slag may be withdrawn.  The gas produced comprising mainly carbon monoxide and hydrogen is then mixed with the gases already produced and which have been freed from carbon dioxide.  In another example crude oil is cracked at a temperature of 720 DEG  C., the entrained coke is removed in a cyclone separator and the gases and vapours washed with oil. The heavy residual oil is returned to the process, the remaining gases and vapours are separated, the vapours being converted into carbon monoxide and hydrogen as in the first example whilst the gases after removal of carbon dioxide are separated into olefines and methane hydrocarbons with more than one carbon atom.  Ethane, propane and butane are converted into ethylene in a fluidised bed and the methane is cracked with oxygen, steam and carbon dioxide in a chamber containing a nickel catalyst at 800 DEG  C. to produce synthesis gas. The gaseous mixture of carbon monoxide, hydrogen and olefines is converted into propionaldehyde, butyraldehyde and C5 aldehydes at 200 DEG  C. and a pressure of 250 atmospheres with an aqueous cobalt acetate solution as catalyst.

Title: Integrated circuit with anti -"latch-up" circuit obtained using complementary mos circuit technology
Inventor: RECZEK WERNER
IPC: H01L27/092
Filed: 1996-04-03
Abstract: Integrated circuit having anti latch-up circuit in complementary MOS circuit technology. Due to the incorporation of non-linear elements between the ground (Vss) and the p-conductive semiconductor substrate (Psub) and between the supply voltage (VDD) and the n-conductive semiconductor zone (Nw), the risk of the occurrence of the latch-up effect triggered by the build-up of base charges at the parasitic vertical and lateral bipolar transistors is diminished. The space requirement for the non-linear elements to be additionally incorporated is low and the circuit properties of the MOS transistors are not influenced as a result thereof. The realization of the non-linear elements can ensue with Schottky contacts or with additional MOS transistors that are wired as diode elements. A realization in the form of buried diodes of polycrystalline silicon (PSi) is also possible, realized, for example, as barrier layer diodes.
