Title: Improvements in or relating to the production of beryllium
Inventor: DERHAM LESLIE JACK
IPC: C22B35/00
Filed: 1959-05-05
Abstract: In a process for the production of beryllium by reduction of beryllium fluoride with magnesium, the reactants are prepared by briquetting a mixture of magnesium particles and ammonium beryllium fluoride and heating the briquettes in vacuo to remove ammonium fluoride gas.  The briquettes may then be pressed to densify them. In order to obtain a fluid melt at the reduction temperature, the beryllium fluoride and magnesium may be present in the briquettes in stoichiometric proportions and the reduction performed in a bath of fusible salt e.g. calcium chloride. Alternatively, the beryllium fluoride may be present in excess in the briquettes this excess providing the necessary fluidity in the final melt.

IPC: H01G4/255
Filed: 1941-07-01
Abstract: 550,502. Grinding electrical condensers. DUBILIER CONDENSER CO. (1925), Ltd. (Dubilier, W.). July 1, 1941, No. 15476/42. Divided out of 550,419, [Group XXXVI]. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 2, 1942.] [Class 60] [Also in Group XXXVI] A grinding apparatus is described for adjusting the capacity of each unit of a multiple condenser to a standard value. Initially each unit is of slightly greater capacity than is desired. The sheet or stack is then placed on a table 32 capable of movement in any direction in its plane. An abrasive wheel 14, driven by a motor 12 is tiltably mounted, under the control of a solenoid 18. A connection is made between the common contact strip of the condenser assembly, mounted on the table, and one end of a resonant circuit Ll C1, while the other end is connected in turn by a lead 63 with the other terminal of each of the separate units in turn. The abrasive wheel 14 on being depressed to grind away one edge of a coated surface of one of the units will continue until the capacity of the unit is reduced to a predetermined standard at which point the oscillations set up in the oscillator-detector valve circuit shown cease so that the plate current through the electromagnet 28 is increased, to open the circuit of the solenoid 18, thereby lifting the wheel 14 from the condenser under test. Fig. 2 shows a machine for effecting the adjustments of capacity to each of the series of condensers in turn, by automatic action. The table 43 slides laterally, operated by a gear 64 working in a rack, and is moved lengthwise of. the condenser strips by the movement of the support 40 which is operated by an angular vane 68 bearing on one of a series of pins 69. Both of these movements are energised by a motor 45 through worm and wheel gearing. The capacity adjustment of each condenser unit is effected as in the example previously described.
