Title: A method of artificially producing ergot
IPC: C12P17/18
Filed: 1961-11-10
Abstract: Ergot is produced artificially by cultivating in the presence of oxygen a culture of Claviceps purpurea with an aqueous nutrient medium comprising a source of carbon and nitrogen, the carbon source being a sugar containing in the form of an hexitol more than 10% of the total source of carbon, and the nitrogen source consisting of ammonium salt of an organic acid, the cultivation being carried out at a pH in the range 4 to 7, the proportion of the carbon source being kept sufficiently in excess of that of nitrogen source to maintain a fat content in the mycelium of at least 10% by weight measured on a dry basis, interrupting the cultivation when the highest content of ergot per unit volume of culture has been attained and separating the ergot from the culture.  The sugar is sucrose or glucose with sorbitol or mannitol (as hexitols) in proportions of 2-30% of the aqueous medium.  The organic acid forming the ammonium salt may be a saturated or unsaturated acid having 2 to 6 carbon atoms and 1 to 3 carboxylic groups with or without hydroxyl and/or keto groups, e.g. oxalic, citric, fumaric, malic, lactic or pyruvic acids; the ammonium ion content of the salt comprising 0.05 to 1.0% w/v. of the medium.  In the case of surface culture, substances increasing the viscosity of the medium e.g. agar, gelatin or methyl cellulose may be added to the liquid medium in quantities of 0.01 to 2.0% weight/volume. A suitable nutrient medium consists of sucrose, sorbitol, citric acid, ammonia, calcium nitrate, magnesium sulphate, potassium di-hydrogen phosphate, agar and tap water.  At the end of the cultivation, ergotamine is isolated both from the mycelium and from the fermentation medium by known methods. Specifications 755,555, 757,696, and 837,423 are referred to.

Title: Process for the production of carbonaceous fuel combustible briquettes
Inventor: SOPPET WILLIAM WARD
IPC: C10L5/14
Filed: 1962-10-26
Abstract: Combustible briquettes are produced from a mixture of a major amount of a finely-divided carbonaceous fuel and a minor amount of a binder which forms a thixotropic paste or gel with water, a thermosetting synthetic resin, a curing agent, if necessary, therefor and water, by shaping and curing, the curing being effected by high-frequency heating, for example by placing the briquettes on one of two spaced electrodes at high-frequency alternating voltage. Suitable binders include carbohydrate materials such as dextrins, starch and wheat flour (which are preferred), cellulose ethers, pectic, proteinaceous or vegetable materials, sulphite lye, or inorganic materials such as bentonite clay or waterglass.  The resin may be liquid (preferred) phenol-formaldehyde or urea-formaldehyde, a specified curing-agent for the latter being NH4Cl + urea + water, or solid mixed powdered novolac and hexamethylene tetramine or spray-dried urea-formaldehyde resin.  Anthracite is the preferred fuel. Sodium nitrate or saltpetre may be added as anti-smoking agents when bituminous fuels are used. Example 3 specifies by weight, 2000 parts anthracite dust, 200 water, 40 wheat flour, 40 aqueous urea-formaldehyde, condensate of 70% solids content, and 4 parts curing agent comprising NH4Cl (0.32), urea (1.6) and water (2.08).

[Also in Division D1] Apparatus for depositing a coating of powder on a moving strip comprises a circumferentially grooved rotating metering roll 10 situated at the outlet of a powder container 12, means e.g. pressure plate 15, for pressing powder into the grooves, scraper means 17, 18 for removing excess powder from the surface of the roll, means e.g. blades 19, for removing the powder from the grooves and means e.g. vibrating screen 13, for breaking up the removed powder and depositing it on the strip 14. The vibrating screen 13 may be formed from a series of wires spaced apart horizontally and vertically and extending transversely of the strip, the wires forming rows, and alternated rows being offset with respect to the row above . Two banks of rows of wires may be disposed one above the other. In an alternative embodiment, the screen is formed from a series of coaxial semi-cylindrical expanded metal grids. The screen is preferably vibrated by means of a compressed air-actuated rotating ball vibrator, and is mounted for horizontal movement on ebonite members. An electric potential may be applied between the screen and the strip, the metering roll being either charged or earthed. In the case of the roll being charged, it should be maintained at a higher potential than the screen, and the screen situated nearer the strip than the roll. A vibrating plate 16 may be provided in the powder container 12 to prevent bridging of the powder, and the pressure plate 15 may be perforated to return excess powder to the container 12. The apparatus is particularly suitable for depositing metal powders e.g. aluminium, nickel, zinc, stainless steel and titanium, the powders being thereafter compacted and sintered.

Abstract: 842,439. Selective punching apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Dec. 18, 1958, No. 40958/58. Class 31 (2). Punching apparatus comprises a plurality of punches each of which is supported for independent lengthwise movement into and out of a die and has corresponding selectively operable means adapted to constrain it against lengthwise movement towards the die while energy is built up in a spring co-operating with the punch, said energy on release of the punch by said means being utilized to move the punch, through material to be punched and into the die. As shown in Fig. 1, the punching apparatus comprises punches 15, arranged in rows and columns, supported by a carrier 8 reciprocable towards and away from a die 1, each punch being surrounded by a compression spring 20 extending between a shoulder 17 on the punch and an abutment plate 21, movable with the carrier, and each punch being fitted at its end with an armature 19 which is associated with a selectively operable stationary electromagnet 26 adapted, when energized, to constrain the punch against lengthwise movement during the initial period of movement of the carrier towards the die thereby to build up energy in the spring 20 which energy on release of the punch, when the electromagnet is de-energized, causes the punch to move with and relative to the carrier to effect movement of the punch through a statistical card or tape to be punched and into the die. A resilient buffer 22 movable with the plate 21 is adapted to absorb surplus energy in the punches. To prevent rotation of the punches about their longitudinal axes, the shoulders 17 are each provided with flat opposite sides which co-operate with guides 25 fixed to a stripper plate 4.

Title: Process for the alkylation of aromatic hydrocarbons
IPC: C07C2/68
Filed: 1958-12-29
Abstract: In the alkylation of an aromatic hydrocarbon in the presence of BF3 the effluent is separated into a gas containing BF3 and a liquid which is fractionated to separate unreacted aromatic hydrocarbon which is recycled, monoalkylated hydrocarbon product and polyalkylated hydrocarbon, at least part of which is contacted with the gas in an absorber to dissolve BF3 and the resultant solution is recycled to the reaction zone.  Preferably a dialkylated hydrocarbon is separated for use as the absorbent.  The starting aromatic hydrocarbon may be monocyclic, polycyclic or condensed polycyclic and may have side chains.  The alkylating agent may be a cyclic or acyclic mono-olefin, diolefin, acetylene, alcohol, ether or ester; gaseous olefins are preferred, they need not be separated from non-reacting gases.  Mixtures of alkylating agents may be used, e.g. ethylene and propylene can be used to form ethylbenzene and cumene from benzene.  Make-up BF3 may be added in solution but is preferably added as gas.  The reaction zone is preferably packed with an inorganic refractory oxide.  Many starting materials and reaction zone packing materials are specified. Conditions used are - 18 DEG to 260 DEG  C., 1-200 atmospheres pressure (sufficient to keep the aromatic hydrocarbon liquid) with an L.H.S.V. of 0.25-20, a mol. ratio of aromatic hydrocarbon to alkylating agent of 2-20 : 1 and using 0.1 mg.-0.8 g.
