Abstract: 385,243. Magnetizing and demagnetizing permanent magnets. HAUSER, A., 34, Karl - Marxstrasse, Linz - on - Donau, Austria. Aug. 16, 1932, No. 22993. Convention date, Aug. 19; 1931. Addition to 379,337. [Class 35.] In the magnetizing apparatus of the parent Specification comprising a polarized relay connected in parallel with alternating current magnetizing coils for interrupting the circuit thereof, the permanent magnet of the relay is replaced by an electromagnet fed by rectified current obtained from the main alternating current supply. The relay comprises an alternating current magnet 4 connected to mains 2, 3 in parallel with magnetizing coils M, a continuous current magnet 5 fed through a rectifier G from a transformer T the primary of which is connected across the mains 2, 3, and an armature 6 attached to a pivoted member 12 supporting a movable contact 8 in the circuit of coils M. The member 12 is biased by gravity to occupy the position shown. The object to be magnetized is placed within the field of coils M, and with switch S3 in the full line position shown, switches S1, S2 are closed. At 'the crest of an alternating current half wave of predetermined direction, the armature 6 is attracted to the pole 31 against the action of pole'30, the circuit of the coil M is opened at contacts 7, 8 and remains open as long as magnet 4 is energized. Subsequent release of the armature and closure of contacts 7, 8 is facilitated by a spring 32. Rheostats 19, 23 are provided to control the relative strengths of the magnets 4, 5. With switches S1 closed, S2 open and S3 closed in the dotted line position, coils E, M are supplied with alternating current so as to function as demagnetizing coils.

Filed: 1928-08-10
Abstract: 295,687. Barrett Co., (Assignees of Miller, S. P.). Aug. 17, 1927, [Convention date]. Liquid fuel.-A composite pitch composition is obtained by subjecting tar to distillation by direct contact with hot coal distillation gases to produce a high melting point hard pitch residue which while still hot is blended with tar to form a homogeneous mixture suitable for use as a liquid fuel, a creosoting composition, or a roofing composition. Part of the up-take pipes 2 of a battery of coal retorts 1 are connected to a collector main 3 of usual construction, where the hot coal gases are treated in the usual manner with ammonia liquor, the gaseous products passing to condensers 6, 7 and the tar oils condensed being led to receivers 18, 19, 20. The remaining up-take pipes are connected to a short collector main 21 where the gases are sprayed with tar obtained from the collector main 3 through a pipe 10, decanter 11, receiving tank 12, and pipe 15. The pitch residue is removed through a pipe 24 to a mixing tank 25 to which tar is also supplied through a pipe 26 and the mixed product is removed through a pipe 30. to a tank 31. Oils vaporized in the mixing chamber are condensed in a condenser 27 and returned through a pipe 28. The gases produced in the short collector main pass through an electrical precipitator 33 to condensers 34, 35 and the oils obtained are blended with the tarry oils formed in the condensers 6, 7 to form creosoting compositions. Pitches having melting points from 300-400‹ F. are obtained.

Abstract: 914,258. Waveguide attenuators. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 8, 1959 [July 11, 1958], No. 23485/59. Class 40 (8). [Also in Group XXXVI] A variable waveguide attenuator comprises a body C of semi-conductive material having a #-i-n structure, the pzone P and the n-zone N being situated outside the waveguide and the zone of intrinsic conductivity within it. The body may comprise a thin plate of germanium or silicon arranged within central slots S 1 , S 3  in the broad faces of a narrowed section of the waveguide W. Two wires Au, Al of gold and aluminium are diffused into the plate at the regions of the slots whereby zones of n and p conductivity are created in these regions. When the conductors Au, Al are respectively connected to the negative and positive terminals of a high-voltage supply, charge carriers are injected into the central intrinsic zone and are accelerated by the high-frequency field in the waveguide, thus extracting energy from the field. The depth of penetration of the carriers is about equal to the recombination diffusion length of the intrinsic material and this length is made equal to the distance between the wires Au, Al.

Abstract: 978,973. Vacuum switches. ENGLISH ELECTRIC CO. Ltd. June 13, 1962 [June 30, 1961], No. 23647/61. Heading H2B. In a vacuum switch parts of the contacts are " current conditioned " by arc discharges under vacuum and the arcing during operation of the switch is restricted to the conditioned areas by stabilizing electrodes between parts of the contacts which have not been conditioned, the electrodes being made of a material having an arcdischarge voltage greater than half the maximum discharge voltage than can occur between the contacts. In Fig. 1 the fixed and moving contacts 10, 11 are surrounded by a cylindrical metal electrode 13 which is insulated from the contacts and has an annular extension 13a which assists in limiting the arcing to the conditional area of the contacts. In Fig. 3 the moving contact 17 engages the final contact 16 in two extreme positions and the electrodes 20, 20<SP>1</SP> have annular extensions 20a. The contacts may be of copper and the electrodes of tungsten or molybdenum or alternatively the electrodes may include " getter " material such as tantalum, zirconium or titanium and have a corrugated surface. The cylinder 13 or plates 20 may be extended to shield other parts of the switch from " line of sight " arcing.
Patent GB-752552-A (GB)
Title: Improvements in and relating to growth factors
IPC: A23K1/00
Filed: 1953-08-27
Abstract: The invention comprises a growth factor prepared by cultivating an Aspergillus in a culture medium containing carbohydrates, a nitrogen source, a magnesium salt, a phosphorus compound and oligo elements (particularly copper), in Roux bottles or vats with agitation, said factor differing from the known substances produced by Aspergilli in that it is soluble in water but insoluble in organic solvents such as acetone, ether and absolute alcohol, and neutral in aqueous solution, and in that it does not constitute an antibiotic as it does not have a bacterial spectrum, the product having a very strong growth action in regard to some bacteria of the group of antibiotic bacilli, particularly certain sporulated bacteria.  The growth factor is extracted from the sub-mycelial juice by normal methods such as atomization, precipitation, e.g. with phosphotungstic acid, or selective precipitation.  The application of the growth factor to the bacteria of the Subtilis mesentericus group yields a large variety of enzymatic and antibiotic secretions.  Examples describe the preparation of the growth factor using Aspergillus flavus.ALSO:The invention comprises a preparation for the systematic feeding of livestock, particularly to increase their strength and resistance to disease, which comprises a growth factor obtained by cultivating an Aspergillus in a culture medium containing carbohydrates, a nitrogen source, a magnesium salt, a phosphorus compound and oligo elements with agitation, and is characterized in that use is made of powder extracted from the submycelial juice, purified or otherwise, or of mycelium stabilized and dispersed before drying on a support which may contain vitamin or other substances.  A chicken food comprises finely divided mycelium with half its weight of bran which is added in a proportion of 0.5-2 per cent to a complete paste ensuring normal equilibrium in nitrogenous, carbohydrate, mineral materials and containing in addition oligo elements and vitamins necessary for the growth of young animals.  Water polluted by Coli bacilli may be purified by the addition of a culture medium of bacilli of the Subtilismesentericus type, the development of which has been accelerated by means of the growth factor obtained by cultivating an Aspergillus.ALSO:A growth factor obtained by cultivating an Aspergillus in a culture medium containing carbohydrates, a nitrogen source, a magnesium salt, a phosphorus compound and oligo elements with agitation, increases the growth of bacillus of the Subtilis mesentericus group and also of a certain number of non-pathogenic bacteria, particularly in the case of certain Clostridia.  This action also extends to a number of saprophytic micro-organisms, to which action the growth factor owes its preventative and curative action in certain animal maladies.
