Title: Improvements in electric switches
IPC: H01H21/42
Filed: 1930-03-10
Abstract: 342,183. Snap-action switches. S. S. WHITE DENTAL MANUFACTURING CO., 211, South 12th Street, Philadelphia, U.S.A.-(Assignees of Angell, R. C.; Prince Bay, Staten Island, New York, U.S.A.) March 10, 1930, No. 7719. Convention date, Nov. 1, 1929. [Class 38 (v).] Forward or backward rotation of a spindle 35 causes a contact brush 65, pivotally mounted on the spindle, alternately to engage successive members of two series of circularly arranged contacts on two opposed blocks 1, 2, the two series being in staggered relation to each other. The blocks 1, 2 may e.g. each have five contacts 8 and 21 respectively. The contact brush 65 is pivoted upon a pin 37 mounted between ears in a member 36 fixed to the spindle 35 and is acted upon by a dead-centre spring 63 arranged between a projection of the member 36 and a link 62 which engages a slot in the contact brush. Also mounted on the pin 37 is a member 70 also acted on by a dead-centre spring similarly arranged behind the spring 63. The fixed contacts 8, 21 are segmental and divided by ribs and when the spindle 35 is rotated, the members 65, 70 rotate with it until an ear 77 on the member 70 encounters a rib. This forces the member 70 to the right, its deadcentre spring completing the action, and during this movement the ear 77 strikes the contact brush 65 and carries that over to the right into engagement with a contact 21, the dead-centre spring 63 completing the action. Further rotation of the spindle 35 moves the members 65, 70 back again and so on.

Abstract: 876,624. Making rotors. FIRTH CLEVELAND Ltd. July 2, 1957 [Dec. 7, 1956], No. 7754/61. Divided out of 876,611. Class 83 (2). [Also in Group XXVI] A flat metal strip 1, Fig. 1, is punched to shear it along lines 4, and transverse elements 5 are upset out of the plane of side portions 6 (only one of which is shown). The strip 1 is bent into cylindrical form, as shown in Fig. 2, with its ends 24 abutting and with its elements 5 projecting inwardly to form rotor blades 22. The circumferential spacing of the rotor blades is reduced by corrugating or crimping the side portions 6. Alternatively, a second strip 21 may be provided, with its blades 23 intercalated with the blades 22. The rotor is completed by cast end discs 51, Fig. 5, having annular recesses 55 to receive the side portions 6. The end discs may be restrained from moving apart from one another. Alternatively, tabs 57 are formed on the side portions 6 and project through slots 56 in the end discs, the tabs being corrugated or, as shown, bent over to retain the end discs. The rotor is balanced by breaking off projections 58. In an alternative construction, Fig. 8, each end disc 81 has retaining lugs 89 which are bent down into holes 83a in the side portions. The rotor may be used in a transverse-flow fan or pump such as described in Specification 876,611 (see Group XXVI). One of the end discs may be integral with the rotor of the driving motor.

Title: New hydroxynaphthyl-pyrimidines
Inventor: KEATS GEORGE HAROLD
IPC: C07D239/42
Filed: 1962-03-01
Abstract: The invention comprises hydroxynaphthyl pyrimidines of <FORM:1028922/C2/1> in which one R is a hydroxyl group and the other R is a hydrogen atom or a hydroxyl group and A stands for a pyrimidyl radical directly connected to the naphthalene nucleus by one of the carbon atoms in the 2, 4 and 6 positions of the pyrimidine ring.  The pyrimidine ring may carry on at least one of the three carbon atoms not attached to the naphthalene ring a halogen atom or an amino, substituted amino, etherified hydroxyl, mercapto, substituted mercapto, sulphonic acid or heterocyclic radical. These substituents may be, for example, chlorine and bromine atoms, thiocyano and sulphonic acid groups, methylamino, ethylamino, dimethylamino, b -hydroxyethylamino, di-(b -hydroxyethyl) amino-, cyclohexylamino, anilino, sulphoanilino, disulphonanilino, carboxyanilino, sulphocarboxyanilino, methoxy, ethoxy, butoxy, phenoxy, methylphenoxy, chlorophenoxy, sulphophenoxy, disulphophenoxy, nitro sulphophenoxy, sulphonaphthoxy, methyl thio and sulphophenylthio groups; groups of formula <FORM:1028922/C2/2> in which Y represents the group of atoms necessary to form a 5- or 6-membered ring; quaternary ammonium or pyridinium groups, group of the formula <FORM:1028922/C2/3> in which R3 and R4 are alkyl, cycloalkyl, aryl o aralkyl groups, or R3 and R4 together complete a 5- or 6-membered heterocyclic ring, and groups of the formula <FORM:1028922/C2/4> in which R5 and R6 are hydrogen or hydrocarbon groups. The new compounds may be prepared by condensing 1-naphthol, 2-naphthol or 1,3-dihydroxynaphthalene with a pyrimidine compound having a halogen attached to at least one of the 2-, 4- and 6-positions of the pyrimidine ring and other substituents as required, in the presence of a Friedel-Crafts catalyst, e.g. aluminium chloride. Alternatively, the compounds may be obtained by condensing the naphthol with a pyrimidine compound containing halogen atoms, in the positions where substituents are required and replacing these by known methods with the desired substituents. For example, the halo-substituted compounds may be treated with amines, alcohols, phenols, alkali metal sulphites, thiocyanates, mercaptoheterocyclic compounds, thioamides and dithiocarbamates. Examples are given of the preparation of (a) dichloro-(41-hydroxynaphth-11-yl) pyrimidine; trichloro-(41-hydroxynaphth-11-yl)-pyrimidine; (c) dichloro-di-(b -hydroxyethyl)amino - (41 - hydroxynaphth - 11 - yl) - pyrimidine; (d) chloro-di-(b -hydroxyethyl)-amino -(41-hydroxynaphth-11-yl)pyrimidine; and (e) bis-di-(b -hydroxyethyl)amino-(41-hydroxynaphth -11-yl)pyrimidine.

A fibrous mat (e.g. fibre-glass) is impregnated with thermosetting resin and drawn by suction into the corrugations of a former 1 where the resin is cured by heating. In the drawing, the former is a rotating cylinder 1 consisting of an outer cylindrical member 4 linked by radial air-tight partitions 6 to an inner cylindrical member 3 which is mounted on a fixed pivot 2 having a chamber 7 as shown communicating with a suction pump. Holes 5<SP>1</SP>, 19 in the members 4, 3 allow suction to be applied to those parts of the surface of the former 1 opposite an arc-shaped heating means 10. A fibrous mat 17 to be corrugated is impregnated with resin at F 5  and then, together with forming sheets 13, 14 (later removed), is fed by conveyers 23, 24 between splicing rollers 25, 26 which stick the upper and lower forming sheets 14, 13 together at the edges (using adhesive). The sandwich 13, 17, 14 is pressed into the corrugations of the cylinder 1 by soft, spring-loaded rollers 29, 30 and held in them by suction until emerging from the region of the heater 10. Final hardening of the resin may then be done in a thermal tunnel. An alternative embodiment mentioned has a former consisting of a corrugated foraminous sheet mounted on a conveyer belt which carries it over two rubber shoulders sliding in grooves in a vacuum chamber, to apply suction to the former; the whole assembly being in a hot tunnel.

An armoured, low voltage, polyphase distribution cable has fluid-tight-insulated phase conductors stranded with an uninsulated, neutral conductor which is in contact with a metal band over its whole length. As shown, Fig. 1, the phase conductors 1 are sector-shaped P.V.C. sheathed copper or aluminium. The uninsulated neutral conductor 2 is in contact with the helical stranded metal strips 4 and 5, which provide both screening and mechanical protection. Strips 4, 5 are protected by an outer sheath 6 which may be of conducting, semi-conducting or insulating material. In the case of a non-insulating sheath 6, strips 4 and 5, and hence the neutral conductor are earthed over their entire lengths. The neutral conductor may be of mixed constitution, comprising steel wires for rigidity and/or parallel conductor wires. If the neutral conductor wires are of aluminium, the neutral conductor has a lead sheath 7 (Fig. 2, not shown) for protection from oxidation and corrosion. Phase and neutral conductors are stranded with a relatively large pitch to facilitate junctions to the phase and neutral conductors.
