Title: Improvements in and relating to electric switches and switch mechanisms of the press-button or plunger type
IPC: H01H13/60
Filed: 1942-10-09
Abstract: 559,600. Snap-action switches; actuation of switches. RIDINGS, T. Oct. 9, 1942, No. 14189. [Class 38 (v)] An insulated member bearing bridging contacts is pivoted to a body-member rotatable in a base which has sets of contacts on to which the contact member may be depressed selectively in its several positions. As shown a body member 20 can rotate on a base 10, and carries a contact member 28 bearing three spring-pressed bridge contacts 29 held by pins 29a, 29b, 29c. The base carries a series of separated contacts 12a, 12b, 12c, and 12d of varying sizes and spacings, and an arc contact 11. so that, on depression of the pivoted arm 28, various circuits may be connected according to the rotary position of the arm. The switch is shown in closed position. Operation of the arm is effected with a snap action by pressing button 46, whereupon a wire link 40 tilts a pivoted member 38 over the deadcentre of a spring-pressed linkage 32, 33 operating the heel of the arm 28 to raise it from the contacts. Spring 47 returns the link 40 to the other end of the slot 39, turning a roller 45 in the member 46 to show " ON " or " OFF through an aperture therein. In certain positions of the rotary body 20 a press rod 17, normally held away by a spring 18, may be operated to give retractive operation of certain contacts by bearing in each of such positions, on a spring 13 which is thus caused to make contact with an arc contact 11 below and connected to the upper arc contact 11.

Title: Process for the manufacture of water-insoluble azodyestuffs
IPC: C09B29/20
Filed: 1934-05-10
Abstract: Azo dyes are made in substance, on a substratum or on the fibre by coupling a diazotized 4 : 6-dihalogen-3-anisidine with the anilide or a p-alkoxyanilide of 2 : 3-oxynaphthoic acid.  Vivid red shades fast to light, chlorine and boiling are obtained.  When produced by a printing process as resists under dyeings with diazotized 4-aminodiphenylamines they yield clear red shades fast to light.  In examples the following dyes are produced in substance or on cotton: 4 : 6-dichlor-3-anisidine --> p-anisidide; 4-chlor-6-brom-3-anisidine --> the anilide.  In a further example cotton tissue is impregnated with the anilide, printed with a paste containing diazotized 4 : 6-dichlor-3-anisidine and aluminium sulphate, dried, developed with diazotized 4-amino-4<1>-methoxydiphenylamine, exposed to air, introduced into a bath of hydrochloric acid and finished; a clear red beside a full deep blue is obtained.  Specifications 6379/12, [Class 2 (iii)], 17279/13, and 195,600, [both in Class 15 (ii)], are referred to.  The Specification as open to inspection under Sect. 91 refers also to the use of the p-phenetidide of 2 : 3-oxynaphthoic acid.  This subject-matter does not appear in the Specification as accepted.

[Class 123 (iii)] [Also in Groups XXVII and XXXIV] In a method of separating entrained oil from an enclosed atmosphere above an oil well, for example, above a crank-case of an internal combustion engine, a slight vacuum is produced in the atmosphere and an oil separator or filter unit is fitted on the suction outlet, the oil collected by the unit being returned from the suction side of the unit by a conduit leading to below the oil level in the well. In the construction shown in Fig. 1, a crank-case 10 of a diesel engine is fitted with an oil separator 13 in a casing 12 connected through a pipe 14 with inlet manifold. Entrained oil sucked through the separator collects in drops thereon and is returned to the crank-case through an oil seal comprising a pipe 15 and a well 16 provided with an outlet 17. The separator comprises flat screens alternating with corrugated screens, finer screens being on the upstream side of the separator. In the arrangement shown in Fig. 2, a casing 20 contains screens 21 of cylindrical form and the separated oil flows through a pipe 25 to a well 27 provided with an outlet 27a. The casing is connected by an attachment 28 to the crank-case which may be supplied with fresh oil through an opening 29.
