Title: Photomultiplier tube circuit
IPC: H02M1/15
Filed: 1968-01-08
Abstract: 1,140,555. Valve supply arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 8 Jan., 1968 [12 Jan., 1967], No. 1031/68. Heading H3W. [Also in Division G1] In a photomultiplier tube circuit comprising a tube 12 operated from a voltage regulated power source 10 and having dynodes D1-D10 connected to taps on a voltage divider network 18 connected across the source 10, the cathode 16 is connected through a resistor R3 to the negative terminal of the supply and through a capacitor C3 to the positive terminal of the supply. The small value of the cathode current allows of a large value being used for resistor R3, so that capacitor C3 and capacitors C1, C2 in the filter network 14 can be of relatively small value without the production of hum ensuing. The photomultiplier shield 19 is biased via resistors R4, R5 series connected in shunt to resistor R6. The power supply 10 consists of a variable amplitude square wave generator, a step-up transformer and a full wave rectifier, its output being regulated in accordance with the light intensity means of a connection 11 to resistor R7 in series in the anode circuit of the tube.

Abstract: 146,054. Tartara, G. G. B. Jan. 13, 1920. Addition to 131,149. Kinematograph apparatus. - A camera for taking either one or a succession of pictures as described in the parent Specification is fitted with improved controlling-apparatus. In the construction shown in Fig. 2, the notched disk 50 on the main shaft of the mechanism, which is driven by hand or clockwork, is normally locked by the lever 102. To take a number of pictures, the press-button 66 is held down and may be retained under the catch 115 so that the whole mechanism is free to operate. To take a single photograph, the press-button 71 is operated, which, in moving the lever 102, releases the disk 50. The same operation, however, moves the slide 108 to cause the arm 109 to engage a notch on the disk 50. The time lag between these two operations allows sufficient rotation of the disk to permit of one photograph being taken.

Title: Improvements in or relating to the production of glutamic acid and betaine hydrochloride
Filed: 1948-01-16
Abstract: Steffen's filtrate is treated with sulphuric acid to give a pH between 2.0 and 2.9, inorganic sulphates are separated and the resultant solution brought to between pH 0.2 and 1.0 with hydrogen chloride and betaine hydrochloride isolated therefrom.  After removal of the hydrochloride the residue may be hydrolysed and glutamic acid isolated from the hydrolysate.  Preferably the Steffen's filtrate is concentrated to a specific gravity between 1.2 and 1.4, treated with conc. sulphuric acid to a pH of 2.7 at not above 70 DEG  C., and sulphates, e.g. of sodium and potassium, allowed to crystallize and removed at 0-50 DEG  C.  The filtrate is then concentrated to between 50-90 per cent of the weight of the original Steffen's filtrate, treated with anhydrous or conc.  HCl at not above 70 DEG  C. to give a pH of between 0.2 and 1.0, preferably 0.6, and betaine hydrochloride is allowed to crystallize and removed at 0-35 DEG  C., preferably 20 DEG  C.  The resultant filtrate is hydrolysed, preferably with a non-oxidizing mineral acid such as conc.  HCl, at 100-125 DEG  C. for 1/4 -4 hours and the pH adjusted to 1.6 with an inorganic alkaline compound, e.g. sodium, potassium or ammonium hydroxide, filtered from inorganic salts at 40-60 DEG  C., optionally after concentration to a weight of 55-90 per cent of the original Steffen's filtrate, and the pH of the resultant filtrate brought to 3.2 by one of the above alkaline agents, preferably ammonia, when after standing for several days the deposited glutamic acid is recovered.  The above acidic hydrolysate may be processed in various ways, e.g. salts and insoluble organic matter may be removed directly after hydrolysis, the PH of the filtrate adjusted to 16 and concentration effected until salts again crystallise or the hydrolysate may be concentrated directly after pH adjustment to 1.6 until salts crystallize.  Hydrolysis may be effected with sulphuric or phosphoric acid as well as hydrochloric acid or alkaline reagents, e.g. sodium hydroxide or calcium oxide or hydroxide may be used.  For alkaline hydrolysis, preferably not more than 10 per cent of reagent based on the weight of Steffen's filtrate is used, the temperature being below 100 DEG  C., preferably 85 DEG  C., and pH adjustment to 1.6 is made with acidic reagents, e.g. those specified for acid hydrolysis.  Alkaline hydrolysates of raw Steffen's filtrate or of Steffen's filtrate from which inorganic salts and betaine hydrochloride have been removed by the above process may be used to adjust the pH of acid hydrolysates, prepared as above, to a value other than 3.2, e.g. 1.6, and the process continued as above described.  An example is given which is similar to the preferred method detailed above.

Fixed sieves; reciprocating sieves; plant for screening and grading granular material; pneumatic separating: separating between rotary rollers.-A portable machine for cleaning beans or other kinds of grain consists of a vehicle on which is mounted the cleaning apparatus including mechanism for separating out chaff and dirt, mechanism for separating rough or imperfect from smooth grain, mechanism for polishing the grain, means for transferring the grain in its passage from one mechanism to the next, and a power shaft for operating all the parts. Fig. 1 shows the apparatus mounted on a motor vehicle 2, the engine of which drives the power shaft 6. The grain from the thrashing machine is delivered into the boot of an elevator 24, consisting of an endless belt 25 with buckets 26, which delivers it by the shoot 55 and a hopper 9 with an adjustable gate 10 to superposed screens 11, 13 which separate the coarse tailings and straw and the heavy sand and dust. The grain from the screen 13 passes by an air trunk 15 to the boot 22 of a second elevator, being subjected in its passage to a blast from the fan 16 which discharges the fine dust through the hood 17. The fan is driven from a pulley on a shaft 31, which carries an eccentric 36 for reciprocating the screens 11, 13. The elevator 23 carries the grain from the boot 22 and delivers it to the sorting device comprising a hopper 29 having a conical floor and openings 34 adjacent the inner ends of pairs of rollers 35. The hopper is carried by a disc 60 which is rapidly rotated by a vertical hollow shaft gearing with a shaft 49 and the grain is moved over the pairs of rollers 35 by centrifugal force. Simultaneously, a disc 61 in gear with one of each pair of the rollers is driven by the shaft 49. The rotation of the rollers on their axes causes the rough or imperfect grain to pass into a fixed hopper 38 and to the outside of the machine while the smooth grain passes over into another hopper 37 by which it is delivered to the polishing device consisting of a helical brush 42 rotating in a cylindrical sieve 41. The grain is finally discharged by a spout 45 with a movable gate 46.

Wells ceasing to produce because the formation pressure is insufficient to lift a column of degasified oil are recompleted by injecting foam to force at least part of the column back into the formation, closing-off the well until the oil from the column has gasified, and opening the well so that the foam is ejected and the well produced. A well may be chemically treated by introducing a slug of chemicals into the formation by injecting the foam, this process being finished before the oil has time to gasify. A gelatine plug may separate the oil and foam to permit use of high density foam and a gelatine plug may be formed on the top of the foam and water then supplied to increase the pressure on the formation. A slug of corrosion inhibitor may be forced down the well by the foam, gelatine plugs being inserted between the oil and the inhibitor and the foam and the inhibitor.
