Patent GB-805014-A (GB)
Title: Streptomycin and dihydrostreptomycin sulfates
Filed: 1956-06-01
Abstract: The calcium chloride complex of streptomycin is converted to the corresponding sulphate salt by contacting an aqueous solution of the calcium chloride complex with an anion exchange resin on the sulphate cycle.  The streptomycin sulphate so produced may then be converted to dihydrostreptomycin sulphate by catalytic hydrogenation with e.g. platinum oxide.  It is preferred to use a resin which is an organic nitrogeneous anion exchange which derives its exchange capacity essentially from quaternary ammonium groups, e.g. "Amberlite" IRA-400 (Registered Trade Mark).  The contact time of the complex on the exchange bed is insufficient to result in the precipitation of calcium sulphate within the resin bed and should be within the range 15 to 60 minutes.  The resin bed is preferably longer than its diameter and may be 10 feet high.  Rate of flow of liquid through bed may be brought about by (a) introducing air under pressure to top of column; (b) using a pump to feed solution into column; (c) withdrawing effluent under vacuum.  The resin is put on the sulphate cycle by e.g. treating with aqueous sodium sulphate or with aquous sulphuric acid and aqueous sodium hydroxide.  The effluent cuts rich in streptomycin sulphate are separated, methanol added to precipitate calcium sulphate which is filtered off and the filtrate treated with excess methanol to precipitate the streptomycin sulphate. Alternatively, the rich cuts may be filtered to remove any precipitated calcium sulphate, the filtrate hydrogenated at 24 lbs. pressure using a platinum oxide catalyst, filtered, methanol added to precipitate calcium sulphate and then excess methanol to precipitate dihydrostreptomycin sulphate.  The forecut and mixed cuts obtained from the resin column and which contain dilute streptomycin sulphate, and chlorides and sulphates of streptomycin and calcium, respectively, are used as solvent for additional streptomycin calcium chloride complex in feed make up vessel, any calcium sulphate which precipitates being removed.

Abstract: 1,002,689. Drying apparatus. McGRAWEDISON CO. April 24, 1964, No. 17049/64. Heading F4G. Apparatus for drying garments, comprising a drying chamber 10 containing a rotary perforated basket 16, a distributer 44 disposed adjacent the basket and having openings 46 proximate the surface thereof and a combustion chamber 48 disposed vertically, externally of the drying chamber 10, is characterized in that mono-port gas burners 56 are disposed below the lower open end of the chamber 48 with their upper ends at the entrance to the chamber, a gas shut-off valve is provided for the burners, the upper end of the combustion chamber 48 communicates with the distributer 44 and in that the combustion chamber is of sufficient length to effect complete combustion before entry into the distributer. The basket 16 is mounted for rotation on the forward end of a shaft 18 which is supported in the rear wall of the chamber 10 by bearings 20. A motor M drives the shaft 18 through a system of pulleys. Baffles (not shown) control the flow of drying air around the basket. A shroud 64 surrounds the combustion chamber 48 and defines with the chamber a passage for the intake of air directly into the distributer 44. An exhaust fan 72 operated by the motor M draws air from the drying chamber at a rate greater than that at which the drying air leaves the combustion chamber 48 to ensure that any leakage takes place into the box. A pressure-sensitive device comprises a hinged damper disposed on the outside of the chamber 10 over an opening in the wall. A rise in pressure within the chamber causes the damper to swing open and in turn operate the gas valve to shut off the gas burners. When the pressure has been corrected the valve is opened and the burners are lit automatically by a pilot. The flow of gas is thermostatically controlled so that with a reduction in moisture content of the garments the input temperature of the air is reduced.

Title: Improvements in signalling devices for use on railroads
IPC: B61L3/10
Filed: 1939-06-16
Abstract: 530,080. Signalling on trains. GREEN, H., and FROST, J. F. June 16, 1939. No. 17574. [Class 105] A signal showing whether a track section is clear or occupied is given in the cab by means of a wiper 31 on the train co-operating with track switch devices 1, 2 at the entrance and exit ends of the section respectively. Both devices are spring supported and are depressed by the wiper. The wiper is rotatably mounted so that it may be set for the engine working backward or forward, and carries insulated contacts 15, 16, 17. When the train enter an unoccupied section a contact bar 3 of device 1 bridges contacts 15, 16 to close the circuit of an electromagnet 19, the pivoted armature 20 being thereby attracted to close contacts 21 in the circuit of a green signal lamp 23. The contacts 21 remain closed after magnet 19 is de-energized until arm 20 is operated. Bar 3 is connected to the core 5 of a solenoid and is depressed by the wiper to close contacts 7, 8 in the solenoid circuit whereby the bar is further depressed and held out of the path of the wiper on a following train. When the train leaves the section a contact bar 11 of device 2 is depressed and opens contacts 13, 14 in the solenoid circuit to restore device 1 to normal position. At the same time bar 11 bridges contacts 16, 17 to close the circuit of an electromagnet 25 whereby armature 20 is attracted to break contacts 21 and close contacts 26 in the circuit of a red lamp 27. A train normally enters a section with red lamp 27 lit, and if the entered section is occupied device 1 has been made inoperative by the preceding train so that the red indication is not changed. To warn the driver that a track device is about to be passed a train contact moves over a series of fixed track contacts 28 to close intermittently the circuit of a warning lamp 30.
