Patent GB-289781-A (GB)
Title: Improvements in or relating to variable electric condensers
IPC: H01G5/38
Filed: 1928-04-28
Abstract: 289,781. Soc. Belge Radio-Electrique. April 30, 1927, [Convention date]. Condensers comprise two armatures each operatively associated with a variable capacity device, and adapted to be actuated in succession by a control shaft in such a manner that each is at rest during movement of the other. A small variable condenser may also be supplied for compensating stray capacity. Two sleeves c, c<1> are interconnected by a spring r and freely mounted on the control shaft e, to which are keyed two small sleeves f, f<1> having conical faces which frictionally engage similar faces m, m<1> for alignment purposes. The sleeves c. c<1> end in traylike members in which are adjustably screwed segments g, g<1>, the screws h, h' passing through oval holes in the trays to vary the zero capacity. Fixed stops l, l<1> are provided on the condenser frame, and adjustable stops j, j' are screwed into the sleeves f, f<1>, which carry a brass comb d for the moving plates. Referring to Fig. 5, the spring r is so tensioned as to try to turn the segment g<1> and its movable plates in a clockwise direction, and the segment g and its plates in an anti-clockwise direction, but the former is prevented by the engagement of the segment g<1> with the stop j<1> and the latter by the engagement of segment g with the stop l. When the shaft e is rotated clockwise, the stop j<1> rotates and allows the segment g<1> and its plates to rotate through 180‹ until the segment is arrested by the fixed stop l<1>. During all this movement, the segment g remains held against its stop l and no movement thereof takes place, but the stop j is rotated clockwise by the shaft e and at the end of the movement engages the top of the segment g. Thus for the second half-turn the segment g and its plates are rotated by the stop j whereas the segment g<1> is held against the stop l<1>. The reverse takes place on reverse rotation of the shaft through 360‹. The sleeves and segments may be of cast material and cast together. The small condenser, Fig. 3, comprises plates fixed, to supports u, t, of which t is movable along cross pieces s, s<1> to which it can be fixed by small screws, as shown. The Specification as open to inspection under Sect. 91 (3) (a) refers to a modification in which the axes of the armatures are perpendicular to the control shaft axis. This subject-matter does not appear in the Specification as accepted.

In an example, the brightener is mixed with a molten polyester at a temperature of 250 DEG -280 DEG C. under nitrogen; the mixture is then extruded to form fibres or films.ALSO:Naphthotriazoles of the general formula <FORM:0928160/IV(a)/1> wherein at least one X is a hydrogen atom and the other X is a hydrogen or a chlorine atom, are prepared by diazotizing the appropriate chloro-substituted stilbenamine <FORM:0928160/IV(a)/2> then coupling the diazo compound with 2-naphthylamine, and finally oxidizing the monoazo dye to the triazole.  The oxidation may be carried out by dissolving the dye in pyridine or picoline, and heating the solution with copper sulphate. The naphthotriazoles have use as brightening agents for nylon, polyacrylonitrile and polyesters of terephthalic acid (see Groups IV(a) and IV(c)).  The preparation of 2-chloro-4-stilbenamine by the reduction of 2-chloro-4-nitrostilbene, by means of iron borings and hydrochloric acid, is described.ALSO:Naphthotriazoles of the general formula <FORM:0928160/IV(a)/1> wherein at least one X is a hydrogen atom and the other X is a hydrogen or a chlorine atom, are fluorescent and have use as brightening agents for textiles.

Abstract: 892,685. Thermal switches. RUSSELL, W. M. April 8, 1960 [April 16, 1959], No. 13017/59. Class 38 (5). [Also in Group XI] In an electric kettle a single circuit breaker element is located in a housing outside the boiling space and is designed to be actuated by two independent thermal switch arrangements. When the water in an electric kettle boils a jet of steam 51 is directed out of the heating chamber on to a bimetallic spring 45 housed in a separate chamber, causing the free-end of the spring to. push an axiallyslidable member 77 against a snap-action switch actuating member 69 pivoted about a toggle spring 66, a transverse pin 76 on the member 69 being arranged to force contact buttons 56, 57, or spring blade 55 and blade 58 respectively apart, thus cutting of the supply to the heating element. In the event of the kettle boiling dry a safety device comprising two bimetallic members 35, 36 arranged so that on heating their free ends move to the right and left respectively is provided and a tensile stress is placed on member 36 by means of an adjustable screw 78. In a normal heating operation the movement of the free end 36 is stated to be negligible but when the kettle boils dry the heating of member 35 causes it to bend to the right and bimetallic member 36 will be insufficiently heated to counteract the tensile force in it and will move to the right also, its free end abutting against part 81 of member 69, thus actuating the switch and cutting of the supply to the device. The thermal switch is reset manually.
