Abstract: 1,017,542. Combined timepiece and time switch. DIAMOND H. CONTROLS Ltd. July 3, 1964 [Aug. 12, 1963], No. 31769/63. Heading G3T. [Also in Division H2] A motor 1 drives clock hands 4 and 7 and also rotates a twelve-hour dial 8a coupled by a friction clutch, shown diagrammatically at 9, to an "off" cam 10 which is coupled by a further friction clutch 16 to an "on" cam 15. A follower 17 extending across both cams opens contacts (Fig. 2, not shown) when depressed by either. Cam 15 is secured on a shaft 12 which passes freely through cam 10 and carries an adjusting knob 14 and pointer 13. A pointer 11 is attached to the boss of cam 10. To set the time switch the knob 14 is turned anti-clockwise until a raised part of cam 15 engages an arm 10a extending from cam 10; cams 15 and 10 with pointers 13 and 11 then move together until the desired "off" time is indicated on dial 8a by the pointers; knob 14 is then turned clockwise, leaving cam 10 and pointer 11 set but moving cam 15 until the desired "on" time is indicated by pointer 13. Cams 10 and 15 have substantially similar cut-away portions which now overlap by an amount equivalent to the desired duration of the "on" period, and the follower 17 is held depressed by cam 15 (at least). The cams are subsequently driven clockwise with dial 8a until cam 15 allows follower 17 to rise, closing the switch contacts at the time indicated by pointer 13. At the time shown by pointer 11 the cam 10 depresses follower 17 and the contacts are opened. Manual operation of the contacts may be effected by a knob (Fig. 1, not shown) which cams the "fixed" contact into a position where it engages the moving contact whatever the condition of follower 17.

Title: Improvements in or relating to liquid-insulated a.c. electric circuit-breakers
IPC: H01H33/75
Filed: 1936-11-20
Abstract: 485,579. Liquid break switches. REYROLLE & CO., Ltd., A., LEESON, B. H., and BRIERLY, R. H. Nov. 20, 1936, No. 31794. [Class 38 (v)] In a liquid-insulated A.C. circuit-breaker of the plain-break type, in which lengthening of the arc or arcs by bowing due to the electrodynamic forces set up by the arrangement of the contacts and of the conductors leading thereto occurs, in order to prevent undue lengthening, a slotted or perforated insulating member is disposed adjacent the contacts in such a position as to obstruct the bowing, the slots or perforations being of such dimensions as to prevent the arc from passing through them and bowing out on the remote side. In a multi-break circuit-breaker, an insulating member is disposed adjacent one or more of the sets of contacts. The insulating member, or arc grate, is further of such dimensions as to prevent the arc from bowing out past its edges, whereas the slots or perforations provide an outlet at C for arc-gases. In the single-phase breaker of Fig. 1, the arc grate is carried by the oiltank A and comprises a thick slotted fibre or other insulating plate B, or two plates with registering slots, or a number of superposed spaced horizontal slats, the vertical thickness of the slats, or of the parts of the plate B between the slots, being made small. The corresponding dimension of the slots B<1> is also made small, for example, one-third of the thickness of the plate B. The structure is supported by side-plates D which may be of wood and form part of, or be carried by, the insulating tank-lining A<1>. The front of the structure is close to the point where the arc is formed between the movable contacts F, F<1> and the fixed contacts E, E<1> supported by an insulating bushing E<2> on the cover. In a single-break switch, the former are carried on an arm pivoted to a second bushing in the cover, but in a two-break switch employing a movable bridge-member with contacts F, F<1> at the ends, the arrangement shown in Fig. 1 is duplicated. Since the resultant electrodynamic forces acting on the arcs of a polyphase breaker may tend to move them at an angle to the contact-plane, the sides of the grate may have oblique walls G, which may either be solid and divert the arc into the slots, Fig. 3 (not shown), or may be provided with continuations G<1> of slots B<1>, Fig. 4, or alternatively, Fig. 5 (not shown), the grate may be curved so as to replace the slotted flat plate and oblique walls of Fig. 4. The slots may be divided by vertical partitions to produce a lattice-formation, and the grate may in some cases he mounted on the fixed or moving contact. Fig. 6 shows a pair of movable contacts K pivoted to connections K<1> crossing one another to the bushings K<2>, which support a slotted horizontal plate L just above the path of the single arc drawn out horizontally between those contacts.

Title: Method of removing phenolic contaminants from water
Inventor: BROWN KENNETH MICHAEL
IPC: C10G67/02
Filed: 1961-09-06
Abstract: Phenolic constituents are removed from water by contacting the water with crude oil, thereby desalting said crude oil while transferring a major portion of the phenols to said crude oil.ALSO:A crude oil is contacted with water containing phenolic contaminants, whereby the oil is desalted and the major portion of the phenols is transferred from the water to the oil.  This oil is then separated by fractionation into a low boiling fraction substantially free of phenols, an intermediate phenol-containing fraction having an initial boiling point of approximately 150 DEG  C. and a final boiling point of approximately 340 DEG  C., and a higher boiling fraction substantially free of phenols.  At least a part of the intermediate fraction is subjected to hydrogenative treatment at 150-650 DEG  C. to recover an essentially phenol-free fraction, for example employing a hydrorefining catalyst such as the oxide or sulphides of cobalt and molybdenum on a refractory oxide such as alumina. Preferred pressures are 3.4 to 340 ats. using 1 to 20 moles H2 per mole of hydrocarbons. The catalyst preferably contains 1-10% of the cobalt compound and 2-15% of the molybdenum compound by weight.  Other catalyst mentioned are nickel oxide or sulphide, tungsten sulphide, platinum, or palladium.  Other refractory oxides include silica, magnesia, thoria, or zinc oxide, or mixtures thereof, either with alumina or especially with silica.
