Title: Improvements in or relating to the manufacture of driving springs
IPC: B21F35/00
Filed: 1953-08-24
Abstract: 766,799. Making springs. THIEBAUD, H. Aug. 24, 1953 [Oct. 27, 1952; Feb. 24, 1953; Feb. 24, 1953], No. 23340/53. Drawings to Specification. Class 83 (2). In the manufacture of a driving-spring for a time-piece such as a clock or watch, piano wire is flattened by rolling to the desired cross-section of the spring metal. To compensate for work hardening due to rolling, the wire may be tempered for one hour at 360‹ to 380‹ C., or alternatively, if the rolling is effected in two operations, the heat treatment may be given between rolling operations. As an alternative, the heat treatment may be given after rolling to remove the hardened outer layer of the rolled wire. Instead of heat treatment, the resulting hard layer may be subsequently removed by mechanical grinding or polishing or by electrolytic treatment; these processes may alternatively be performed between rolling operations. A specific example is given of the kind of piano wire used and of the electrolytic treatment for removing the hardened surface layer.

Title: A process for the production of diarylmethanes
IPC: C07C2/86
Filed: 1959-07-08
Abstract: Diarylmethanes are produced by the condensation of an aromatic hydrocarbon with formaldehyde in the presence of aqueous sulphuric acid of 55%-70% by weight concentration by adding the feed hydrocarbon and formaldehyde continuously to the reaction mixture which is maintained at a temperature such that water and feed hydrocarbon are evaporated and withdrawn, the vapour stream is condensed and the hydrocarbon layer returned and a bleed stream is removed from the reaction mixture and from the hydrocarbon phase is separated (a) unconverted feed hydrocarbon which is returned to the reactor and (b) diarylmethane which is recovered as product.  The acid catalyst may also contain 2%-10% by weight of an ether alcohol having 3 to 6 carbon atoms per molecule and 0,8%-5% by weight of a trivalent arsenic compound, e.g. sodium arsenite or arsenious oxide. Specified hydrocarbons are toluene, xylenes, 1, 2, 4-trimethylbenzene, ethylbenzene, ethyltoluenes, ethylxylenes, diethylbenzenes, cumene, isopropyltoluenes and isopropyltoluenes. The formaldehyde is preferably added in solution in the aromatic hydrocarbon or water, e.g. as a 1%-60% by weight aqueous solution, commercial formalin being preferred.  Suitable ether alcohols are di- and triethylene glycol, dipropylene glycol or the methyl or ethyl ether of ethylene glycol.  Suitable conditions are 100 DEG  - 170 DEG C. and a molar ratio of unreacted aromatic hydrocarbon to formaldehyde of 30-2,000 : 1.  The reaction mixture is preferably circulated through conduits and a vessel having stirring means.  A bleed stream is taken off from the conduit, separated, unreacted aromatic hydrocarbon separated and recycled and diarylmethane recovered.  Acid catalyst is also separated and recycled. Aromatic hydrocarbon is added to the conduit and formaldehyde added at a point between the point of such addition and the vessel.  Any formaldehyde which is vaporised may be recovered. In the steady state the circulating mixture preferably contains 90% by weight or more of reaction products in the hydrocarbon phase and a hydrocarbon to aqueous phase volume ratio of 1 : 0,025-10, the volume of circulating emulsion to added hydrocarbon being 10-1,000 : 1.  The diarylmethanes may be cracked as described in Specification 766,498 to produce the starting hydrocarbon which may be recycled and a hydrocarbon with one more methyl group.

Abstract: 594,412. Lining moulds. UNITED STATES PIPE & FOUNDRY CO. Nov. 28, 1944, No. 23728. Convention date, Dec. 4, 1943. [Class 83 (i)] Mould materials; centrifugal casting- machines.-A horizontal centrifugal mould for casting metal tubes is given a rough insulating lining by spraying the inside with a liquid suspension of a powdered refractory material and a binder while the mould is heated to 260‹-800‹ F. A suitable composition may be produced by mixing 500-1000 grams of silica, flour with 10-40 grams of bentonite and 1 litre of water. The material is stirred while spraying and its composition, the shape and direction of the jet, the distance between mould and nozzle, the pressure of the atomizing air &c. may be varied to give the required degree of roughness so that the mould surface will retard relative movement of molten metal and reduce the rate of cooling by the amount desired to give an improved casting. The coating layer may be built up to 0.002 to 0. 08 inches in thickness and have 10 to 120 protuberances per lineal inch which project from 0.001 to 0.05 inch.

Abstract: 345,248. Brakes. CLARK, D'A. M., 5, Chancery Lane, London.-(Bendix Brake Co. ; 401, Bendix Drive, South Bend, Indiana, U.S.A.) Dec. 18, 1929, No. 23822/30. Divided on 337,268, [Class 103 (i), Brakes &c.] [Class 103 (i).] Blocks and shoes acting on drums ;compensating for wear.-Relates to brakes of the kind comprising a pair of shoes of which the first applies the second with one direction of rotation of the drum and the second applies the first when the drum rotates in the other direction. The ends of the shoes remote from the cam abut directly one on the other and a guide is provided for these ends. The other ends of the shoes anchor the one against an eccentric stop and the other against a bracket which carries the floating camshaft. Automatically adjustable frictionally-held stops maintain a constant clearance of the shoes from the drum. The shoes 14, 16 each comprise a pair of stampings of channel form secured together back to back. The lower ends are rounded and in direct contact and are guided by a fixed channel section plate 20 which embraces the upper part of the ends of the shoes so as to prevent both lateral and upward movement of the shoes. The shoes are applied by a cam 46 carried by a spindle 42 mounted in a bracket 40 slidably attached to the back plate of the brake by bolts 50 passing through slots 52 in the plate. A flange 48 on the cam positions the shoes laterally. The cam when turned engages the end-plate 36 of the shoe 16 and the reaction causes a projection 38 on the bracket 40 to force the shoe 14 against the drum. According to the direction of rotation of the drum, the braking torque of the two shoes is transmitted to the back plate either by a rotatable eccentric stop 28 which passes through an opening in the shoe 16 or by engagement of the end of the shoe 14 with the projection 38 causing the bolts 50 to abut on the ends of the slots 52. For automatically adjusting the clearance of the shoes from the drum a pair of plates 56 are frictionally clamped to each shoe by a bolt 58 passing through a slot 60 in the shoe. A fixed pin 62 passes through openings in the other ends of the plates, these openings being larger than the pin by an amount which determines the clearance of the shoes. If on account of wear the movement of the shoes in applying the brake exceeds this amount the plates are shifted and the shoes are permitted to return only by the amount determined by the clearance of the pins 62 in the plates. Springs on the pins 62 serve to restrain lateral movement of the shoes.

Title: Alarm clock with an arrangement for the automatic alteration of the volume of sound during running down
Inventor: JUNGHANS HELMUT
IPC: G04B23/10
Filed: 1950-09-29
Abstract: 698,810. Clocks. JUNGHANS, H., and JUNGHANS AKT.-GES., GEB. Sept. 29, 1950 (Oct. 10, 1949]. No. 23895/50. Class 139. An alarm clock comprising a device for automatically changing the ringing volume during the running down of the alarm spring is characterized by a member connected through a friction coupling with a part of the alarm mechanism and co-operating with stops determining its initial and/or its end position, said member having a cam-portion directly intercepting the alarm hammer before it comes into contact with the sound element and a recessed portion leaving the hammer free to come into contact with the sound element. The cam member 17, Fig. 1, frictionally mounted on the spindle 6 of the alarm spring 7 is recessed at 17a and co-operates at its periphery with a V-bend 10a on the hammer lever 10. The arrangement is such that when the alarm. spring unwinds the lever 10 is oscillated in the usual way, its amplitude of oscillation being restricted by the V-bend 10a striking the circular periphery of the cam 17 so that a "soft" alarm is produced. The cam 17 rotates clockwise with the shaft 6 until arrested by the engagement of a projection 17b on the cam meeting a fixed stop 4a. The recess 17a is then opposite the V-bend 10a so that the amplitude of the oscillations of the hammer lever 10 are increased, the hammer strikes the post 13 and a " loud " alarm is given till the spring 7 runs down or the alarm is shut off. The cam 17 is retained by a spring washer 18, Fig. 3. A pointer 20 fixed to the cam 17 may be latched by an external latch 21, Fig. 4, in either of two extreme positions to lock the cam 17 in its initial " soft " position or its final " loud " position. The cam 17 may be split at the centre and retained on the shaft 6 by its own resilience with or without the addition of a spring clip, Figs. 5 and 8 (not shown). The period of the "soft" alarm may be lengthened by using two similar co-axial complementary cams 17, 22, Fig. 7, having recesses 17a, 22a respectively. The recesses 17a, 22a are initially as shown in Fig. 7 and the projection 17b abuts a turned over projection 22b of the cam 22. As in the prior arrangement the cam 17 is arrested by the stop 4a after nearly a full revolution, the V-bend 10a is still intercepted by the periphery of the cam 22 which continues to rotate. When the projection 22b meets the projection 17b and the cam 22 is arrested the slots 17a, 22a are in alignment so that a "loud" alarm is obtained.
