Title: Process for the production of alkaloid derivatives of lyserqic acid
IPC: C12P17/18
Filed: 1960-07-04
Abstract: Lysergic acid amide and isolysergic acid amide are prepared by fermenting under aerobic conditions an aqueous nutrient medium containing a source of carbon, nitrogen and mineral salt with a new strain of Claviceps paspali Stevens and Hall.  The process is preferably conducted between 22 DEG C. and 30 DEG C. and at a pH between 4.2 and 6, the alkaloid derivatives being isolated by filtration, rendering the filtrate alkaline, extracting with a water-immiscible organic solvent or by absorbtion on a solid absorbant material.  Subsequent hydrolysis with alkali yields lysergic acid or isolysergic acid.  The new virulented strain of Claviceps paspali is obtained by inoculating embryos of Rosen 4n rye, cultivating in vitro and isolating the sub-species from sclerotia on the embryos.  Detailed examples illustrate the preparation of the alkaloids and their hydrolysis to lysergic and isolysergic acid.

Filed: 1920-08-11
Abstract: 171,459. Mordle, L. Dare-. Aug. 11, 1920. Automatic-feed weighers.-In an electricallyactuated automatic weighing-apparatus, the feedshutter is opened and closed by two independent solenoids disposed one on each side of the shutter, and the weigh-pan is tilted to discharge its contents by a third solenoid which is energized simultaneously with the shutter-closing solenoid. After a weighing operation, the rise of the weighbeam G to the position shown in Fig. 1 closes, by means of a spring contact M, the circuit of a solenoid C, Fig. 2, and a double shutter B, B<1> connected to the core of the solenoid is opened so as to feed the material to the weigh-pan E. When the required weight has been delivered the weigh-beam descends, the circuit of the solenoid C is broken, and the circuits are established through solenoids D, K owing to closure of a second spring contact X. The solenoid D closes the shutter B, B<1> and the solenoid K tilts the weigh-pan E by means of a connecting-rod K<2>. The weighed material is discharged down a shoot L the weigh-beam rises, the contacts N, M are opened and closed respectively, and another weighing operation is initiated. After opening the shutter B, B', the current through the solenoid C may be immediately cut off by means of a cut-out switch R operated by tappets on the shutter. To ensure the complete discharge of the weigh-pan, this is temporarily retained in the tilted position by the action of an electromagnet P on an armature O the circuit of the electromagnet being controlled by the weigh-beam. The distance of the weigh-pan from the feed shoot may be adjusted by means of screws S.

Filed: 1958-07-23
Abstract: 894,768. Phase-sensitive circuits. SHAND & JURS CO. July 23, 1958 [Aug. 8, 1957], No. 23779/58. Class 38 (4). [Also in Groups XXXVI and XXXVIII] In a telemetering system (see Group XXXVIII), a phase-sensitive detector comprises a single triode VT3. The 60 c/s. unbalance voltage from a bridge circuit is coupled via transformer 303 to a limiting amplifier VT1, VT2. The square wave output from VT2 is coupled to the grid of VT3, the anode being fed with a reference 60 c/s. voltage from line 91. The anode of VT3 is coupled to the grid of VT4, having its anode fed from a D.C. supply via a relay (not shown). When the voltages at the grid and anode of VT3 are in phase, the valve passes heavy anode current on positive halfcycles so that the grid voltage of VT4 is insufficient to energize the relay. VT3 passes no current when the grid and anode voltages are in opposition so that VT4 passes heavy anode current on positive half-cycles, energizing the relay. The charge on capacitor 331 maintains the relay energized on negative half-cycles.

[Also in Group XX]  The apparatus comprises a fluorescent screen positioned in a housing so that a conical X-ray beam can fall on it, a carrier for a cassette for X-ray sensitive material adapted to carry any one of a set of cassettes of differing sizes, means for guiding a cassette carried by the carrier from a first position outside the X-ray beam to at least one second position within the beam, an X-ray diaphragm for limiting the cone of the beam, a member adapted to be maintained in engagement with an edge of the cassette in a direction transverse to the direction of movement of the carrier to effect a calipering of the cassette, and means responsive to the calipering displacement of said member relative to the cassette carrier to engage the cassette for effecting automatic adjustment of the X-ray diaphragm in accordance with the magnitude of said displacement. As shown, (Fig. 4), the cassette 111 is centred about the vertical in the exposure position by being held between arms 116, 117 on a horizontally-adjustable framing member 112 having a peg engaging in a spiral groove in a sleeve 115 slidable on a square shaft 115a for setting cassette carriage arresting abutments (not shown). The X-ray beam defining means comprises a four-leaf rectangular diaphragm in a housing 102 carried by the X-ray tube housing 101. The cassette housing 105 and the tube and diaphragm housings are telescopically connected by arms 103, 104 and the diaphragm size is automatically adjusted so that the X-ray field is restricted to the film area to be exposed when switch 131 is closed. Using standard film sizes with predetermined relationships between width and height, the width of the film in use is set up on potentiometers 132, 133 by the rotation of shaft 115a, the potentiometers having cooperating studs related to the standard sizes. The taps of potentiometers 136, 137 are adjusted by rotation of a pinion 139 operated by a rack on the arm 103 as the housing 105 is moved relatively to the tube, and the taps of potentiometers 134, 135 are driven by motors 127, 128 also driving the pairs of diaphragm leaves 123, 124 and 125, 126. While the two bridge circuits are out of balance, relays 143, 144 are energized so operating the three-position doublepole switches 143a, 144a to energize the motors 127, 128 and to open switches 147, 148 in the X-ray tube circuit so that during the actual diaphragm adjustment the patient is not subjected to X-rays and no image is produced on the fluorescent screen 109 (Fig. 4). Specification 889,825 is referred to.

Abstract: Para-xylene is oxidized to toluic acid and terephthalic acid at 200 DEG  F with a 30 per cent aqueous solution of a mixture of 85 mol. per cent fuming nitric acid and 15 mol. per cent methane sulphonic acid.ALSO:An oxidizing agent consists substantially of a mixture of nitric acid containing at least 95 per by weight of HNO3 and up to 30 per cent by volume of an alkane sulphonic acid of 1-5 carbon atoms. The preferred amount of sulphonic acid is 2-30 per cent by volume. Commercial fuming nitric acid, an hydrous acid, or acid containing up to 20 per cent excess NO2, may be used.  Compared with nitric acid, the mixture has a lower freezing point and a higher oxidizing activity at low temperature.  It reduces the ignition delay period when used as the oxidizing component of a hypergolic fuel for jet or thrust engines; such a fuel comprises oxidizing and reducing components which undergo spontaneous ignition when mixed.  The reducing component may consist of a mixture of isopropyl mercaptan, n-propyl mercaptan, sec-butyl mercaptan, isobutyl mercaptan, n-butyl mercaptan, and amyl mercaptans.  Other reducing components specified are diethylaminomethyl ethyl sulphide, diallyl sulphide, diallyl aniline, and the mercaptal formed from acetaldehyde and methyl mercaptan.  The oxidizing agent may also be used for the oxidation of organic compounds, e.g. para-xylene to toluic acid and terephthalic acid (see Group IV(b).
