IPC: H01J49/14
Filed: 1973-02-06
Abstract: 1419684 Mass spectrometers SHIMADZO SEISAKUSHO Ltd 6 Feb 1973 [7 Feb 1972] 5789/73 Heading H1D A mass spectrometer capable of detecting different substances having nearly identical masses (e.g. CO<SP>+</SP> and N 2 +, or CH 4 <SP>+</SP> and O<SP>+</SP>) comprises a single analyser with a number of ionization chambers each supplied independently with a different ionization voltage. The sample contains two or more substances whose masses are such that they would not be resolved by the analyser. If for a mixture of two such substances A, B the ion currents resulting from voltages V and V<SP>1</SP> (where V<SP>1</SP> > V) are Ia and I, and the component of I caused by B is Ib, then the partial pressures of the substances are given by  and where S va  is the sensitivity with which the spectrometer can detect A at level V, and S va ', S vb ' are the sensitivities with which the spectrometer can detect A, 5 at level V<SP>1</SP>. In the arrangement shown in Fig. 3, ionization chamber 11, analyser 10 and detector 14 operate at level V with sensitivity S va  whilst ionization chamber 12, analyser 10 and detector 13 operate at level V<SP>1</SP> with sensitivities S va ', S vb '. From a knowledge of these senstivities and the ionization currents measured by meters 16, 15, the partial pressures of A and B can be calculated. The ionization chambers include collinators 23, 231 and reflector electrodes 22, 221. A control circuit 18 applies ionization potentials V, V<SP>1</SP> to anodes 21, 211 and pulses of acceleration voltage to the reflectors 22, 22<SP>1</SP> in turn, so that the two systems operate alternately. The common analyser 10 is of the R.F. quadrupole type. In a modification (Fig. 5, not shown) a single detector is used and the separate ion guns are all arranged on the same side of the analyser and have different entry trajectories. In a further modification (Fig. 6, not shown), both the entry and exit trajectories are different, and a plurality of both guns and detectors is used.

Title: Automatic change-speed gearing, especially for motor vehicles
IPC: F16H61/02
Filed: 1937-03-01
Abstract: 481,000. Change - speed gearing. KRATOCHWILL, A., and SMEKAL, K. March 1, 1937, No. 6032. Convention date, May 12, 1936. [Classes 80 (ii) and 80 (iii)] Change - speed gearing suitable for vehicles is operated by sliding on a driven shaft 10, Fig. 1, a clutch sleeve 12, by flyweights 18 carried on the shaft 10, and alternatively by a hand lever 21. The sleeve 12 has one ring of internal teeth 11 adapted to mesh alternatively with dog clutch heads 1a, 8a, 14a severally upon the clutch shaft 1 and upon sleeves 8, 14 nested about that shaft. The sleeve 8 is driven constantly through a countershaft 3 at second speed, and the sleeve 14 is driven at first speed forwards, or reversely, according as a gear 9 splined upon it has been enmeshed with a gear 6 on the countershaft or with an idler 15. The control sleeve is connected through angle levers 17 so as to be moved axially, as the flyweights 18 move radially on angle pins 16 responsive to the speed of the load shaft 10. The sleeve 12 is connected also through a fork 22 and shaft 20 to the hand lever 21 which turns over a notched quadrant 26 engaged by a spring ball 24 on the lever. This ball 24 has the effect that the governor 18 does not respond to small speed changes, and when the governor does act, it shifts the control sleeve 12 right over to a new gear position with the ball 24 in a different locking recess. The governor can be locked out on any speed by turning a handle 23 round on its own axis. A steep spiral 23<1> comes into play so that the locking ball 24 is clamped down in the recess it is in at the time. In gear changing, the main clutch is opened and the throttle closed by electrical means. In gear positions, the lever 21, Fig. 6, is clear of electric contacts 40. As the sleeve 12 moves to change speed, the lever 21 passes over a contact 40 which energizes a magnet 39 so depressing the clutch pedal 38. The same current energizes a magnet 46, Fig. 8, which moves left against a bias weight 44 an accelerator rod 43 to close the throttle. Means to facilitate the change of dog-clutch engagement may consist of teeth 28, Fig. 4, projecting beyond the other teeth such as 8a and adapted to engage a substantial gap 30, Fig. 3, in the teeth 11 which have a strong leading tooth 32. Alternatively, the nested teeth 1a, 8a, 14a may be square as shown in Fig. 5, and the teeth 11 may be in a ring 11<1> floatingly supported between two sets of springs 11<2>. Each tooth 11 is turnably supported so that its cylindrical engaging end can roll over the coacting square tooth such as 8a.

The carbon courses 6 and 9 conduct high away from the layers 8 and 10 so that the slag does not form an intimate bond with them and the rate of wear is thereby reduced. The layers 8 and 10 protect the carbon from oxidation.
Patent GB-833562-A (GB)
Title: Process for preparation of carbon disulphide
IPC: C01B31/26
Filed: 1957-02-25
Abstract: Carbon disulphide is prepared by passing a gas containing sulphur vapour through a bed of finely-divided electrically-conductive carbon particles to maintain the bed in a fluidized state, passing an electric current through the fluidized bed to maintain it at reaction temperature, e.g. 700-1500 DEG  C., preferably 900-1200 DEG  C., and recovering CS2 from the effluent gases.  The contact time of S and C should be 0.5-10 secs. N2 entering at 21 carries S from heated reflux flask 15 through heated tube 17, superheater 18, and diffuzer 19 into fluidized bed 13 in glass or refractory tube 12.  The bed 13 is petroleum coke produced in a fluidized bed-coking process and calcined, e.g. at 900 DEG  C. for 2 hours to increase the conductivity.  The bed 13 is heated by current supplied through <PICT:0833562/III/1> electrodes 1, 2 and a thermocouple well 20 is also provided, on all of which radiation shields are provided (Figs. 2, 3, not shown).  Additional N2 is supplied through 5 and gas disperser 4 of graphite with a porous carbon top, the latter having thermal insulation, e.g. petroleum coke particles 7 below. The calcination of the petroleum coke may be in a separate fluidized bed reactor, or may be in situ by feeding small amounts of "green" coke to the bed 13 to replace that consumed. Effluent gases are withdrawn through trap 22 and filter 23, where sulphur is removed, to condenser 24, whence CS2 passes to receiver 25.

Title: A process and an apparatus for continuously obtaining pure gallium
IPC: C22B58/00
Filed: 1963-02-18
Abstract: <PICT:0968446/C6-C7/1> A continuous process for the production of gallium comprises reducing gallium trichloride vapour with hydrogen at an elevated temperature, e.g. 1000-1300  DEG C.  In Fig. 1, the crude trichloride is rectified in a plate column 3 and the purified feed from the condenser 4 flows to the reserve flask 5 which in turn feeds flask 9.  Pure hydrogen enters flask 9 by tube 11, the gaseous mixture being reduced in tube 13 heated by oven 14.  Any unreacted trichloride is condensed by blowers 15 and condenser 16 and it returns to flask 9 partly through tube 13, some of it passing right through the oven 14 and entraining the liquid gallium product, and partly through siphon 18.  The gallium product is recovered from flask 9 by means of siphon 10.  Fig. 2 (not shown) has a longer oven 14 and the condenser 19 returns all the condensate immediately back to the oven and thence to flask 9.

Title: A process for the production of bleaching and disinfecting agents
IPC: D06L4/23
Filed: 1920-03-03
Abstract: A stable preparation for bleaching and disinfecting is prepared from alkali bicarbonates and solid basic magnesium hypochlorite.  In the form of tablets, the mixture remains undecomposed for an indefinite time, and on adding to water, the alkali bicarbonate, (sodium bicarbonate is preferably used), attacks the basic magnesium hypochlorite, forming a hypochlorite solution.  As this reaction takes place at a continually decreasing velocity, the content of available chlorine, after a short time, tends to remain constant, for the loss due to spontaneous decomposition is partly counterbalanced by the generation of a further quantity of soluble hypochlorite.  In the first of two examples, dry sodium bicarbonate is mixed with one-third of its weight of basic magnesium hypochlorite, and, in the second, this mixture is agitated with water.
