Abstract: 1275316 Silica supported catalysts FARBENFABRIKEN BAYER AG 19 Aug 1969 [24 Sept 1968] 41355/69 Heading B1E [Also in Division Cl] Bead-form catalyst supports consisting essentially of silica and having a porosity in excess of 60% are prepared by suspending solids in a silica sol, dispersing the resulting mixture into drops of the required size, gelling these drops in a medium immiscible with water and separating the granulate from this medium, wherein finely divided silicate and/or silica fil- 1ers, carbonates and/or metal oxides or hydroxides compatible with a silica sol are suspended as solids in the silica sol, the total weight of the powdered solids amounting to at least 50 % by weight, based on the silica content of the silica sol, the granulates obtained is heated at 100‹ to 800‹C, optionally after washing, most of the cations are removed from the granulate by acid treatment, and the acid-treated granulate is washed and optionally heated at 200 to 800‹C. The silica sol is suitably a stable salt free silica sol with a concentration of at least 15% of silica and a specifica B.E.T. surface of 150 to 400 m<SP>2</SP>/g, the suspension of powdered solids being gelled in the sol by the addition of a gel-forming agent, preferably a aqueous suspension of hydrated magnesium oxide.

Title: Improved electrical system for producing a pulsating direct current
Inventor: AUSTIN JOHN RICHARD
IPC: H02M9/06
Filed: 1963-10-23
Abstract: 1,037,219. Converting. PARTRIDGE, WILSON & CO. Ltd. Oct. 23, 1964 [Oct. 23, 1963], No. 41728/63. Heading H2F. In an electrical supply system for the stator coils of a vibratory feeder, the output current at terminals 5, 6 has an A.C. and a D.C. component, the relative amounts of which are varied to control the feeder. A choke L1 is connected in series with a rectifier D across the output, the rectifier D being by-passed by a variable resistor R. When R is at its minimum resistance setting, no D.C. is produced in the output current by rectifier D, and the choke L1 presents a high impedance to the A.C. When R is a maximum, the D.C. current tends to saturate the choke L1, lower its A.C. impedance, and so increase the A.C. current fed to the rectifier D, thereby increasing the D.C. component of the output current. A capacitor C, preferably a reversible electrolytic type, prevents D.C. from being fed back to the A.C. mains input 3, 4. The variable resistor R may be replaced by a transistor. A resonancedamping resistor R1, a pre-set resistor R2, a switch S and fuses F1 and F2 are omitted in a simplified arrangement (Fig. 1, not shown).
