Abstract: 615,467. Thermally-actuated valves. RICHMOND, T. G., and MACLAREN & CO., Ltd., R. April 23, 1946, No. 12191. [Class 135] [Also in Groups XXXII and XXXVII] A snap-action mechanism for an electric switch or a valve comprises a spring blade or blades a under compression and anchored at the ends thereof. A thermal electric switch, Figs. 1, 2, is actuated by a bimetal strip c moving against an adjustably biassed plunger e<2> to press a plunger f<l> against the contactcarrying centre blade a of an integrally formed resilient plate a of b. The blade b is clamped to a porcelain body c by a bridge-piece c<2> and stressed by a protuberance c<4> and an adjustable stud c thereby giving the plate a, b a transverse curvature so that a contact d<6> secured to the centre of the blade a snaps between adjustable contacts or stops d<1>, d', before the blade has straightened longitudinally. The fixed blade b may form the central member, there being two blades a each carrying a contact d<6>, Fig. 10, or if the blade b is in two parts, the blades a may be connected and carry a single central contact, Fig. 12. In further modifications, a central contact, blade a is in two parts; one clamped to an insulating bridge-piece h carrying twin contacts d<6> and the other having a knife edge bearing in the bridge h, Fig. 15, or both parts having knife edge bearings in the bridge h, Fig. 18 (not shown); or both parts being clamped to the bridge h, Fig. 21 (not shown). In an alternative form, Fig. 6, the blade a is not integral with the blade b, but is held captive thereon at its ends by a superposed blade g similar to the blade b. Instead of using the operating strip c and plunger f<1>, the blades a, b, or one of them, may be bimetallic. The Provisional Specification refers to a multiple pole switch comprising one resilient plate with a plurality of flexed moving blades.

Title: Improvements in tailstocks for machine tools, particularly for gear finishing machines
Inventor: GLUCK ALFRED
IPC: B23B23/00
Filed: 1959-04-13
Abstract: 882,509. Lathe details. ZAHNSCHNEIDEMASCHINENFABRIK MODUL VEB. April 13, 1959, No. 12479/59. Class 83 (3). A fluid-operated tailstock for machine-tools comprises separate means for reciprocating, clamping and securing the sleeve carrying the centre, the securing means operating when the fluid-pressure fails. A member 2 is secured by screws to the housing 1 and carries a coaxial cylinder 4 closed at one end by a plug 5 and at the other end by a cover 11 through which the piston rod of a piston 12 slides. The piston rod is secured to an end plate 17 of the sleeve 15 carrying the centre 34. The cylinder 16 in the sleeve 15 is connected to the cylinder 4 by passages 12a-12c in the piston 12, and sleeveclamping rings 23 are operated by pistons 24 when fluid flows through the passages 25. Three pins 22 arranged at 120 degrees to each other are engaged by a cone 18<SP>1</SP> on a piston 18 if the fluid pressure fails, and through a ring 21 secures the sleeve 15. In operation oil or air under pressure passes from the line 10 through a passage 10a into the end 9 of the cylinder 4 and through passages 12a, 12b to the cylinder 16 of the sleeve 15, thus forcing the piston 18 against the spring 19 and disengaging the pins 22 from the ring 21, sleeve 15 and piston 12 then being moved to the right together. When the centre 34 contacts the work an increase in the fluid pressure moves a member 6 in the plug 5 to the left and fluid flows from the end 9 of the cylinder 4 through the passage 25 and forces two sets of pistons 24, of which there are three in each set spaced at 120 degrees to each other, against the rings 23, thus clamping the sleeve 15. To retract the sleeve, fluid is supplied through line 33 and discharged through line 10. The member 6 is moved to the right (to the position shown) by a spring 7, and the fall in pressure at 25 releases the rings 23, thus allowing the piston 12 and the sleeve 15 to be retracted. Pressure in space 13 moves a plug 14 in the piston 12 to the left and fluid is supplied to piston 18 through the passages 12c, 12b, thus maintaining the disengagement of the securing ring 21. If the fluid supply fails, the piston 18 is moved to the left by spring 19 and the pins 22 are forced radially outward against the ring 21 and the sleeve is secured. Trips 27-29 are operated by a member 30 secured to a rod 26 attached to the spindle 15, and control a known mechanism for automatically feeding workpieces.

Abstract: A dyed silica is prepared in Example 3 as follows: colloidal silica solution is added to an aqueous alkaline solution of beta-phenylethyl polysiloxane, heated at 100 DEG  C. for half an hour, and water is added.  A solution of a triaryl methane siloxane dyestuff (see Group IV(a)) in aqueous hydrochloric acid is added, followed by further acid, forming a green gel, which is washed, filtered and dried.ALSO:The invention comprises silicon-containing triaryl-methane dyestuffs containing one or more cations of the formula <FORM:0882065/IV (a)/1> or <FORM:0882065/IV (a)/2> and their corresponding siloxanes, wherein X1 is hydrogen, an alkyl radical or a -CaH2a Si V3 radical, V is an alkyl radical, a is at least 3, Ar2 is a phenylene radical which may be substituted by alkyl or alkoxy groups, Ar3 is a phenyl radical which may be substituted, Ar4 is a phenylene radical, R is hydrogen, alkyl or alkoxy, and R11 is hydrogen, alkyl or aryl, the cations being in union with chloride or sulphate ions.  The compounds of formula I are prepared by reacting an arylaminoalkylsilane with an arylaldehyde in the presence of a condensation catalyst supplying chloride or sulphate ions, e.g. ZnCl2, HCl, H2SO4, to form the leuco triarylmethane dyestuff which is isolated and oxidized, e.g. with lead peroxide.  The compounds of formula II are prepared by reacting arylaminoalkylsilanes with a 4,41-diaminodiarylketone in the presence of a condensation agent such as phosphorus oxychloride.  The arylaminoalkylsilanes are described in Specification 882,052.  When they contain hydrolysable groups, the siloxanes are formed.  Examples are given.  Apart from their use as dyes, the polymeric compounds are suitable as pigments and as constituents of inks, e.g. a siloxane triphenylmethane dyestuff is dissolved in glycerine and the solution added to water to form an ink.
