Title: Treatment of chlorination residue
Inventor: REYNOLDS JAMES E
IPC: C01F7/56
Filed: 1982-06-18
Abstract: Alkali and alkaline earth metal chlorides contained in a residue of a chlorination process of a feed material of bauxite or clay associated with coal are removed by the addition of sulfuric acid which causes their conversion to their sulfate form and the simultaneous production of hydrochloric acid. The hydrochloric acid can be recycled to the chlorination process. The hydrochloric acid may be utilized, for example, as a binder of the feed material, to prechloridize the feed material or as a portion of the leach solution when the chlorination process is a hydrochloric acid leach.

Title: Electro-optical tube alignment
Inventor: GROVES PHILIP RANGECROFT
IPC: H04N5/228
Filed: 1982-09-09
Abstract: To align the electron beam in a camera tube with the axial focusing field, the target bias is decreased so that only high energy electrons reach the target. The monitored target signal then shows shading, i.e. variation with position in the beam scan. The four corners of the target are monitored, the beam alignment being adjusted in X and Y directions independently by alignment coils to equalize the signals from the four corners. Scanning deflection may require simultaneous adjustment in the opposite sense.

Title: Method and device for rectification of alternating current
Inventor: AMIRKHANOV KHABIBULLA IBRAGIMO
IPC: H01L29/36
Filed: 1981-02-23
Abstract: A method of rectification of the alternating current through creating a gradient of the ratio between mobilities of electrons and holes in a semiconductor by means of a temperature gradient. The temperature gradient and the bipolar conductivity are created through self heating of the material of the semiconductor with the rectified current with simultaneous cooling of a part of the material of the semiconductor, the value of the exponent //c of the temperature (T) dependence of the relationship (b) between the mobilities of the electrons and holes in the semiconductor (b T<s//c>s) being equal to no less than 0.1. The method is implemented with a device comprising a semiconductor working element (2) with non-rectifying contacts (3 and 4) and a cooler (5) adjoining to the working element (2). The dimensions of the semiconductor working element (2) are so chosen as to ensure together with the cooler (4), within the range of working currents, a non-uniform self heating by the rectified current, the gradient of the relationship between the mobilities of the electrons and holes (db/dx) being equal to no less than 0.2 cm<s-1>s and to further ensure the bipolar conductivity of the working element (2).

Title: A self-priming volumetric diluter
Inventor: CALZI CLAUDIO
IPC: B01F25/60
Filed: 1983-08-26
Abstract: The device consists of a preferably transparent vessel (40), incorporating chambers (12, 14) for receiving diluent and sample volumes respectively, two pistons (16, 18) being axially reciprocable therein by means of a driven cam mechanism (42). The diluent chamber (12) has an opening (20) which is connected either with a diluent supply (26) or the sample chamber (14) by a solenoid valve (24). The sample chamber (14) has a diluent inlet (22') and a sample inlet (22) through which the diluted sample is also discharged. The device operates as follows. In a filling phase (Figure 1), solenoid (24) connects chamber (12) with the supply (26), the sample chamber (14) is placed in communication with a sample supply (not shown) and the pistons (16; 18) move downwards to allow filing of the respective chambers (12, 14). Then in a diluter phase (Figure 2) solenoid (24) interconnects the chambers (12, 14) and the pistons move upwards to introduce the diluent into the sample chamber (14) and expel the resultant mixture therefrom. Coordination of the solenoid (24) with the piston movement is achieved by means of an exuder (60, 68) mounted on the cam assembly drive (62, Figure 5).

Title: Filter assembly
Inventor: COOPER ROYDON BRUCE
IPC: B01D46/24
Filed: 1984-08-13
Abstract: A filter assembly incorporates a system for jacking a fitter canister (13) into and out of engagement with a filter head (11). A threaded jackscrew (15) is mated to a threaded portion of the filter head and rotatably mounted on the filter canister, but longitudinally confined near the canister top. The assembly can accommodate a second class lever (46) the fulcrum of which lies in a notch or other recess (44) in the filter head. The jackscrew includes a plurality of circumferentially-spaced lugs against which a portion of the lever can act. The manual application of force to the free end (46B) of the lever creates a mechanical advantage of the jackscrew lugs (48) such that a torque sufficient to free and turn the jackscrew can be generated. Repeated pivoting of the lever against successive lugs of the jackscrew in a ratchet-like manner unscrews the jackscrew, and the captive canister, from the filter head.
