Title: Time switches
IPC: G04C23/34
Filed: 1971-09-22
Abstract: 1358730 Time switches SANGAMO WESTONLtd 22 Sept 1972 [22 Sept 1971] 44237/71 Heading H1N A time switch having a timing dial 10 with adjustable ON and OFF operating tappets 14, 16, is provided with an omit disc 22 capable of receiving one or more detachable omit tappets 54 around its periphery, linkage means 38, 46 being arranged to be entrained by one only of said operating tappets 14 or 16 to step said omit disc 22, and a pair of omit arms 56 (58, Fig. 2, not shown) respectively associated with the ON and OFF switching functions are positioned adjacent to the omit disc 22 such that one or other of the arms is engageable by each fitted omit tappet 54, whereby stepping of the omit disc 22 is effective, depending upon the omit tappets carried by the disc, to inhibit the switching function of either the said one or the other operating tappet 14 or 16 until the next stepping of the omit disc 22. As shown, dial 10 rotates anti-clockwise and tappets 14, 16 act on respective levers 18, 20, which carry pawls not shown, to actuate contacts not shown. Omit arms 56, (58), when moved by a tappet 54 to a position such as 56a, render the appropriate pawl inoperative such that the engagement of the relevant tappet 14 or 16 with its lever 18 or 20 has no effect. The arms 56, (58) lie on each side of the plane of the omit disc 22, and clip-on tappets 54 have radially prominent tongues (55, Fig. 2, not shown) extending across not more than half the axial width of the tappet such that they can act on lever 56 or 58 according to their orientation when fitted. The disc 22 is stepped by an integral ratchet wheel 28 when the nose 39 of link 38 is moved by tappet 14 engaging a nose 52 on link 46. The disc 22 is mounted on a shaft (26) held in slots 30 in front and rear bearing plates, under bias of a detent arm 36, and can be readily exchanged for a twopositions-per-day disc (Fig. 3, not shown) if the timing dial has two ON and two OFF tappets, or a three-positions-per-day disc (Fig. 4, not shown) when three ON and three OFF tappets are provided on dial 10. In the latter case the ratchet wheel 28 has a larger diameter so that the movement of link 38 produces the requisite smaller angular step.

Fluorinated naphthalene derivatives are obtained by reacting a pentafluorophenyl magnesium halide with a conjugated diene or an aromatic compound, and pyrolysing the adduct so obtained. The aromatic compound acts as a conjugated diene in the reaction. Examples are given of the preparation in this way of 1,2,3,4- tetrafluoronaphthalene and its 5-methyl, 6- methyl, 5,7-dimethyl, 6,7-dimethyl and 5-t.- butyl derivatives. Naphthalene derivatives of the formula in which R denotes an alkyl group of 1-4 carbon atoms and y is 1-4, are claimed per se. The reaction is believed to involve the conversion of the pentafluorophenyl magnesium halide into tetrafluorobenzyne of the formula which forms an adduct with the conjugated diene or the aromatic compound, which adduct is then pyrolysed. The adduct from tetrafluorobenzyne and benzene is assigned the formula Adducts from tetrafluorobenzyne and toluene, o-, m- and p-xylene, mesitylene, anisole, durene, naphthalene, t.-butylbenzene, hexamethylbenzene and anthracene are also described and named.

Abstract: 1492057 Casting processes BBC BROWN BOVERI & CO Ltd and L N HOCKING 1 Nov 1974 [5 Nov 1973] 47350/74 Heading B3F [Also in Division F4] In a method of casting in which a metal charge 8 is melted in a crucible 5 by highfrequency electrical heating and passes into a mould 3 via an outlet 6 at the bottom of the crucible, the charge 8 is melted from the top downwards and does not pass into the mould until all the metal has melted. The process may be carried out under reduced pressure in an inert gas atmosphere and a stream of a reducing gas e.g. propane or butane, may be directed at the surface of the metal charge 8 during melting. Instead of using a gas for reducing any oxides present, a layer of colloidal graphite may be provided around the metal charge 8. The crucible is provided with a compressible refractory lining 7, e.g. of mineral wool, and its outlet 6 may be closed initially by a plug (18), Fig. 2 (not shown), of the same material as the charge 8 to allow the melt to attain a temperature 30 C. above its melting point before passing abruptly into the mould. In the embodiment shown, the distance between the turns of the heating coil 11 decreases in an upward direction; in another embodiment, Fig. 2 (not shown) the turns are equally spaced and the coil (11) is surrounded by a second coil (19) which is movable or located only around the upper end of the crucible. The mould is located within a housing 1 which is movable towards and away from a housing 10 surrounding the crucible. Reference has been directed by the Comptroller to Specifications 1,013,851 and 1,394,832.
