Title: Improvements in the electrophoretic analysis of radioactive substances
Inventor: SACHS CHARLES
IPC: G01N27/447
Filed: 1964-09-08
Abstract: 1,081,072. Measuring radio-activity. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 8, 1964 [Sept.17, 1963], No. 36766/64. Heading G1A. Radio-active substances are analysed by subjecting them to electro-phoresis and measuring the radio-activity at points along the electrophoresis medium. The medium comprises a paper or plastics strip 12 which dips into electrolyte 14, 15 and to which a potential may be applied by electrodes 10, 11. The strip is covered by a plate 19 opaque to radiation having holes 22 containing copper discs 20 with slits transverse to the strip 12. Geiger counters 18 measure the radio-activity of the strip beneath the slits. The counters are located as close to one another as their size allows. The sample is introduced under one of the counters and the output of that counter and those nearer the anode is recorded. The level to which the output of the counter at the point of introduction falls indicates the activity of elements present colloidally as these do not migrate, and elements in the ionized state and combined with protiens are indicated by peaks on the records of the other counters.

Title: Continuous flow type centrifuge and fluid temperature control therefor
IPC: G05D23/19
Filed: 1960-10-27
Abstract: 903,182. Automatic temperature control systems. BECKMAN INSTRUMENTS Inc. Oct. 27, 1960 [Nov. 13, 1959], No. 36909/60. Drawings to Specification. Class 38 (4). [Also in Group II] A continuous flow centrifuge has a rotor disposed in a chamber and stationary sample fluid feed and removal lines. The fluid being fed to the centrifuge is stored in flasks disposed in a liquid bath and the fluid lines are enclosed by a tube and a cooling liquid flows through the annulus so formed. The temperature of the sample fluid in its passage through the rotor is maintained constant by controlling the flow of refrigerant to coils within the chamber or of current to a heating element in the chamber, by an automatic control network responsive to an electric signal from a temperature sensing element installed adjacent to the exit from the rotor. The control network is of the dutycycle control type wherein the duration of constant amplitude current pulses is varied so that the average energy supplied to the heating element is controlled. The current pulses can also operate a solenoid valve to control the flow of refrigerant to the coils. The temperature of the liquid in the annulus is sensed by a thermistor, the output of which is compared in a comparator with that of the rotor sensing element to produce one output when the annulus temperature is above the rotor temperature and another output when the annulus temperature is below the rotor temperature and the two outputs are applied, respectively, to cooling and heating units associated with the bath. Specification 899,543 is referred to.

Title: Improvements in or relating to the continuous production of liquid explosive nitric esters
Inventor: BLAIR JAMES
Filed: 1955-12-23
Abstract: A process for the production of explosive liquid nitric esters from rapidly esterifiable liquid polyhydric alcohols and nitrating mixed acid comprises introducing fresh nitrating mixed acid into a stream of refuse acid substantially free from suspended nitrated polyhydric alcohol, pre-cooling the resulting diluted nitrating mixed acid during its passage under pressure through a first extended tubular structure which leads into a second and narrower bore tubular structure of a bore at least sufficiently narrow to ensure the maintenance of turbulence in the liquid flowing throughout its length and which leads to a separating device, introducing said liquid polyhydric alcohol into the stream of said diluted acid downstream of said first and larger bore extended tubular structure under positive pressure sufficiently high to overcome the resulting back pressure, said second and narrower bore extended tubular structure being sufficiently long to ensure that the reaction is completed within it and extending to a separating locus horizontally remote from the locus where said polyhydric alcohol enters the stream, and passing the resulting emulsion of nitrated polyhydric alcohol and refuse acid leaving the extended tubular structure at said remote locus into the separating device to separate the nitrated polyhydric alcohol from the refuse acid, and recycling a required portion of the latter. The extended tubular structures preferably comprise two long pipes of 0.75 inch and 0.5 inch internal diameter respectively, the larger bore pipe being connected to the smaller bore pipe by means of a venturi throat into which the polyhydric alcohol is forced through a T-junction.  The nitrating mixed acid may be a mixture of sulphuric acid, preferably oleum, and nitric acid; or a mixture of phosphoric acid and nitric acid.  The polyhydric alcohol may be glycerine or mixtures thereof with ethylene glycol, giving as final products nitroglycerine or mixtures thereof with ethylene glycol dinitrate or nitropolyglycerines.  The Provisional Specification is not restricted in respect of the relative diameters of the reactor pipes.

Abstract: 1351339 Telegraphy SIEMENS AG 11 Aug 1971 [12 Aug 1970] 37600/71 Heading H4P The removal of a telegraphy plug in a teleprinter circuit is sensed by a transistorized monitoring circuit which may be used in a teleprinter subscriber station adapted to perform local operations, the input circuit being then protected against accidental supply of line voltage. In Fig. 2, telegraphy plug terminals 5, 6 are automatically bridged when the plug is inserted, thus turning on transistor T1 and hence supplying a 1 input to gate G1. The gate is primed by teleprinter switching circuit SchL and opens upon "local operation" key LT to open gate G6, via G3, so connecting the teleprinter transmitter S and receiver E together. Diodes D1, D2 protect the transistor against accidental connection to the line voltage.

After etching the metal layers to form word lines normal to strips 5, 7, 9 which constitute the bit lines information is written in by establishing appropriate voltages between selected pairs of bit and word lines to break certain of the connections e.g. 22 by electromigration. To re-write information broken connections may be re-established by application of healing voltages.
