Title: Methods of and plant for producing magnesium powder or powder metal mixtures containing magnesium
IPC: B22F9/12
Filed: 1947-06-04
Abstract: 634,799. Distilling metals; magnesium. AMERICAN ELECTRO METAL CORPORATION. June 4, 1947, No. 14804. Convention date, June 8, 1946. [Class 82(i)] A method of producing magnesium powder by condensation from the vapour phase is characterized by the steps of passing an inert carrier gas through a melt of magnesium, heated to a temperature below the boiling point of magnesium, so that the carrier gas is heated and loaded with magnesium vapours of a pressure substantially corresponding to the temperature of the melt, admixing inert chilling gas with the loaded carrier gas outside the melt so as to reduce the temperature of the carrier gas and to condense a substantial portion of the magnesium vapours to magnesium powder. Predetermined relative quantities of carrier gas and chilling gas may be used to produce magnesium powder of desired particle size. The method may be applied to the production of powder of constituents of magnesium alloys, where all the said constituents boil below 1600‹C, the carrier gas being passed through a melt containing the constituents and being loaded with vapours of the said constituents in succession. The inert carrier and chilling gases may be helium, argon, neon and/or purified hydrogen of dew point below -40‹C. The apparatus shown in Fig. 1 comprises a vessel 10 for containing magnesium or the constituents of magnesium alloy up to a level 15, the vessel being heated by heating means 16 surrounded by a refractory container 12. Inert carrier gas enters the molten charge near the bottom of vessel 10 through pipe 21, valve 24 and pipe 25. The loaded carrier gas leaves the vessel through pipe 17 which is connected to vessel 10 above the level 15 of the melt. The carrier gas is mixed with inert chilling gas injected through nozzle 27 and supplied through pipe 23, cooler 32 and valve 22 from pipe 21. Gas containing metal powder is fed to a cyclone 18 where the powder is separated and periodically removed through valves 39 and 41. Gas leaving the cyclone passes through cooler 36 and a filter 48, which removes any remaining metal particles, before being recirculated by fan 20. Losses of inert gas are made up by fresh gas introduced through valve 42. after passing a moisture trap 43, a trap 44 containing heated magnesium and a cooler 47.

Title: System for controlling the supply of air to an internal combustion engine
IPC: F02M1/00
Filed: 1972-03-29
Abstract: 1342864 Exhaust gas driven turbo-charger SAAB-SCANIA AB 29 March 1972 [5 April 1971] 14816/72 Heading F1B A system for controlling the air-supply to an I.C. engine having an exhaust-gas driven turbocharger and an after-burner in the exhaust duct leading from the engine to the turbine which is supplied with fresh air from the compressor and fuel from an engine controlled pump is characterized in that an electrically driven air pump feeds air to the after-burner when the supply from the compressor is insufficient and that a portion of the exhaust gas leaving the turbine is recirculated to the engine. Exhaust gases leave the engine by a pipe 10 and pass to an after-burner 12 and then to the inlet of a turbine 21 which drives a compressor 22. Air from the outlet of the compressor is directed by pipes 24 and 9 to the inlet port of the engine, the pipe 9 containing a throttle valve 28. A portion of the air is led by a branch pipe 16, containing a throttle valve 29, to the inlet of the after-burner 12. Fuel is supplied to the after-burner by a pump 15 the output of which is controlled by an engine parameter e.g. speed. The majority of the exhaust gases leave the turbine by an outlet 27 which leads to a catalyst chamber 30 in which noxious pollutants are treated, and a minor portion of the gases e.g. 25% is re-circulated to the engine inlet by a pipe 25 containing a throttle valve 26. When the engine speed is low, the air supply to the after-burner is supplemented by an electrically driven fan 17, the amount of air supplied being controlled by a throttle valve 19. Pollutants in the exhaust gases are reduced by (a) further combustion in the after-burner (b) recirculation of part of the exhaust gas, (c) treatment in the catalyst chamber.

Abstract: 829,548. Liquid fuel burners. AUTOCOMBUSTIONS (LONDON) Ltd. May 9, 1956 [May 23, 1955], No. 14838/55. Class 75(1) In a vaporizing oil burner in which a controllable oil supply is fed to a vaporizing pot surrounded by a perforated sleeve contained in a casing mounted at one end upon a fuel utilization device and at the other end carrying an air impeller which supplies air to an annular space between the perforated sleeve and the casing, a portion of the air passes throughthe sleeve perforations whilst the remainder passes about the end of the sleeve remote from the impeller into a combustion region. A cast iron vaporizing pot 14 is supported within a perforated sleeve 4 by a screwed tube 13 connected to a T- piece outside a light alloy or cast iron casing 1. A calibrated rotatable ring 17 mounted on the rear end of the casing 1 carries an electric motor 16 driving an air impeller or similarly suitable fan 7 which draws air through apertures 19 in the casing 1 and apertures 18 in the ring 17. The ring 17 can be rotated manually or by gears to vary the alignment of the holes 18, 19. The mixture of oil vapour and air passes through apertures 8 in the front of the sleeve 4 into the combustion zone. The air supply may also be controlled by varying the voltage and thus the speed of the motor 16. The burner is ignited by a taper inserted into the pot 14 on removal of a plug 21 or by an electrically ignited gas jet inserted through a screw-hole on the opposite side of the casing 1 to the oil inlet. The tube 13 is cleaned by a rod 15 carried by the T-piece 12. The oil and/or air supply may be thermostatically controlled.

Title: Telephone metering costs
IPC: H04M17/02
Filed: 1974-04-04
Abstract: 1423946 Metering pay-stations STANDARD TELEPHONES & CABLES Ltd 4 April 1974 14981/74 Heading H4K In a metering control arrangement for paystations, receipt of a first metering pulse causes first timing pulses to step a counter. If a second metering pulse is received before the counter reaches a predetermined stage thereby indicating a high rate trunk call the counter is "frozen" to indicate the charging rate for the call. The counter is coupled to a read only memory which also has an input from a credit meter and an output of the memory is marked when the caller's credit falls below a predetermined minimum # 0 to cause a pay-tone to be sent to the caller, such an arrangement provides a reasonable period of time for a caller to insert more money before his credit falls below zero e.g. where metering pulses arrive at rates greater than about 1 per 4À5 seconds. If the counter reaches 14 before a second metering pulse arrives the counter is reset and caused to count local timing pulses which occur at a rate of, e.g. 1 per 30 sees. as opposed to a rate of 2 per second for the first timing pulses. If a second metering pulse arrives before the 11th local timing pulse a low rate trunk call is identified and pay-tone is sent to the caller when the credit meter reads zero. In both the above eases, the received metering pulses apparently decrement the credit meter, although this is not stated. If a second metering pulse is not received, the counter resets on every 10th count and also causes the credit meter to decrement by one unit. Pay tone is sent when the credit meter falls to zero.

The invention comprises penicillins of Formula I: where X is H or a substituted or unsubstituted alkyl, alkenyl, aryl, aralkyl or aralkyloxycarbonyl and Y is H or a monovalent radical of a pharmacologically acceptable inorganic or organic base. Typical compounds are 6-(dl-N- benzyl - 1<SP>1</SP>,2<SP>1</SP>,3<SP>1</SP>,4<SP>1</SP> - tetrahydroisoquinolyl - 1<SP>1</SP> - carbonyl) amino penicillanic acid, 6-(dl-N- methyl - 1<SP>1</SP>,2<SP>1</SP>,3<SP>1</SP>,4<SP>1</SP> - tetrahydroisoquinolyl - 1<SP>1</SP> - carbonyl) amino penicillanic acid and their sodium salts. The penicillins are prepared by the acylation of 6-aminopenicillanic acid under near neutral conditions with either a mixed anhydride or an internal anhydride of a 1,2,3,4- tetrahydroisoquinaldic acid of formula wherein Z is H or a substituted or unsubstituted alkyl, alkenyl, aryl, aralkyl or aralkyloxycarbonyl radical and R is alkoxy; or Z and R together form a direct nitrogen-carbon bond to yield the desired free acid, which may be converted into the salt, if desired. The mixed anhydride is formed in situ by reacting the appropriate 1,2,3,4-tetrahydroisoquinaldic acid with an alkylchloroformate in a polar solvent (e.g. acetone) in the presence of a base (e.g. trialkylamine) and the subsequent acylation step is carried out in aqueous solution in the presence of a weak base such as NaHCO 3 . The internal anhydride is produced by reacting 1,2,3,4- tetrahydroisoquinaldic acid with phosgene in a solvent such as benzene. After isolation, acylation is in aqueous acid of pH 4À8 to 5À2 containing a polar solvent, e.g. acetone. The penicillins are acid- and penicillinase-resistant. Pharmaceutical compositions comprise a penicillin of Formula I, or a salt thereof, and a carrier for oral, parenteral, topical or rectal administration. Certain starting materials are described and claimed in Specification 1,209,669.
