Title: Improvements relating to electrical or mechanical tripping devices
IPC: H01H71/10
Filed: 1930-06-19
Abstract: 356,338. Spring motors. MARSTON, G. S. and STATTER, J. G., 16, Great George Street, London. June 19, 1930, No. 18773. [Class 10.] The bell-crank trip lever carrying a weight A<3> is rotated about its shaft a from the dotted to the full-line (set) position by pulling on a cord B, which is anchored at b to a spring drum B<2>, whereupon the pin b engages a shoulder a<1> on the lever and carries it along. During this rotation, the arm A<2> of the lever engages a pin d' on an arm D and rotates it about a fixed pivot d eccentric to the shaft a, thereby setting in motion a gear train terminating in a ratchet wheel G. The lever is retained by a pocket a<2> thereon engaging the pin d, and the bar D is retained by the pawl g engaging the ratchet wheel G, only a small force being required to free the pawl g because of the high transmission ratio of the gear train. When the pawl g is raised, as by a solenoid, the spring E pulls on the pin d to rotate the arm D, the pin d slipping after a time from the pocket a<2> so as to let the lever fall and perform the tripping action.

Title: Brake or clutch assembly
IPC: F16D65/12
Filed: 1970-04-21
Abstract: 1,268,312. Clutch-type disc brakes; friction Clutches. ABEX CORP. 21 April, 1970 [8 May, 1969], No. 19048/70. Headings F2C and F2E. A brake or clutch assembly of structural members arranged in axial alignment about a common axis includes at least one member of friction material without any organic binder arranged freely floatingly in axial and circumferential direction between two relatively rotatable and axially movable structural members for frictional engagement therewith. As shown in Figs. 1 and 2, two, or a larger number of, solid or segmented discs 10 have notches 11 at the outer periphery for engagement with splines of a cage, while a relatively rotatable solid or segmented disc 12 (or more than one such disc) has notches 13 at the inner periphery for engagement with splines of a shaft (not shown). Friction material members 14 in the form of a complete shape or shapes or in the form of facings on a backing is accommodated between the relatively rotatable discs 10, 12. Each friction, material member 14 is free to move rotationally, and, within the limits shown, axially; preferably it is supported radially, between the limits shown, by the provision of a groove 12G, in the adjacent face of disc 12, having a depth less than the thickness of member 14. The boundaries of the groove 12G constitute flanges, and as the friction material wears down, the flanges give visible or audible indication of such wear while there is still some friction material remaining in the groove. In the modification of Fig. 3, flanges 35, 36, are riveted to the relatively rotatable members 30, 32. In Fig. 4, (not shown), all the elements are plain and flat-sided, but the friction material member is protected from one or both sets of shaft and cage splines by a metal split ring on one or both of its radial peripheries. The discs 10 and 12 may be predominantly of beryllium or titanium or ferrous metal or metal oxide or carbon. The friction material members 14 (containing no organic binder) may be a sintered mix such as a bronze mix, or one having an iron base; or they may be substantially of carbon. The members 14 may also incorporate "friction tailoring" agents, dispersed, or concentrated as a backing, to give build-up of coefficient of friction with heating. The discs 10 and 12 may include additives dispersed or provided as a protective coating, e.g. at a war face. One application is to the brakes of large aircraft.

Title: Process for the manufacture of optically active threo-ª-p-nitrophenyl-serine and esters thereof
Filed: 1952-07-31
Abstract: Optically active threo-b -p-nitrophenylserines and their alkyl and aralkyl esters are manufactured by condensing a glycocoll ester or a salt thereof (e.g. the ethyl ester or its hydrochloride) with two molecular proportions of p-nitrobenzaldehyde (if desired in the presence of an organic secondary base, e.g. diethylamine) to produce a mixture of DL-erythro and DL-threo condensation products, separating the former from the mixture, treating the residue with an acidic reagent (e.g. ethanolic hydrochloric acid) to produce a DL-threo-b -p-nitrophenylserine ester, resolving this with the aid of an optically active acid (e.g. bromocamphorsulphonic acid) and, if desired, hydrolysing the resulting optically active esters to the respective free aminoacids.  A further quantity of the desired products may be obtained from the DL-erythro condensation product by treating it with an acidic reagent to produce a DL-erythro-b -p-nitrophenylserine ester salt and converting this to the threo form by either (a) reacting it with an acylimido ester (e.g. acetimido ethyl ester) to form an oxazoline, hydrolysing the carboxylic ester group, opening the oxazoline ring by the action of acid, neutralizing the product to cause migration of the acyl group to the N-atom, and acidifying, deacylating and esterifying the product, or (b) N-acetylating the DL-erythro-b -p-nitrophenylserine ester salt (e.g. with acetic acid, acetic anhydride and sodium acetate), treating the resulting DL-erythro-N-acetyl-b -p-nitrophenylserine with thionyl chloride at ordinary temperature and subjecting the product to aqueous hydrolysis followed by esterification.  The DL-threo-b -p-nitrophenylserine ester obtained by either method is resolved (and, if desired, hydrolysed) as before, or, when using method (a), the process may be modified by resolving the intermediate DL-threo-N-acyl-b -p-nitrophenylserine with the aid of an optically active base (e.g. brucine), deacylating the products and, if desired, esterifying the D- and L-threo-p-nitrophenylserines.  Examples illustrate the various alternative processes as applied to the preparation of the free acids and their ethyl esters.

Title: Improvements in or relating to the production of insolubilised protein artificial filamentary products
IPC: D01F11/02
Filed: 1945-07-30
Abstract: Artificial filamentary products obtained from the spinning of vegetable seed globulins such as peanut proteins, or casein, in aqueous alkaline or other suitable media into acidified saline coagulating solutions are rendered insoluble by treatment in a solution of formaldehyde in substantially saturated sodium chloride solution at a pH between 4 and 6 at a temperature insufficient to soften the filaments and subsequently in an acidified brine formaldehyde solution containing not less than 30 parts of sodium chloride per 100 parts of water by weight and sufficient hydrochloric or sulphuric acid to bring the pH below 1. The unhardened filaments are rinsed free from the coagulating solution with saturated brine prior to the formaldehyde treatment. The formaldehydebrine solution should be in large excess and the time of treatment should vary with the temperature.  At 40 DEG  C. a few minutes should be sufficient, at room temperature a few hours. The concentration of formaldehyde in the solution of pH 4 to 6 may be of the order of 1 to 3 per cent. The second formaldehyde brine treatment may be carried out between 35 DEG  and 50 DEG  C. for several hours.  It is not necessary to maintain the coagulated filaments under tension in either bath, since if contraction does occur products of good handle, lustre and physical properties are obtained.  In an example, a 24 per cent solution of peanut globulin in dilute caustic soda is extruded into a coagulating bath consisting of 2 per cent sulphuric acid, 28 per cent sodium sulphate and 70 per cent water.  The filaments are collected at several times the speed of extrusion.  After being cut into fibres, the material is immersed in a large volume of solution made by dissolving sufficient formaldehyde in strong sodium chloride solution to give a formaldehyde concentration of 1 1/2 per cent, and then adding solid sodium chloride to saturate it.  The pH is adjusted to 5 by the addition of either hydrochloric acid or sodium hydroxide, whichever is required.  The time of immersion is two hours and the temperature 20 DEG  C.  It is removed, drained and immersed in a second formaldehyde-saturated brine bath containing 1 1/2 per cent of formaldehyde and 2 1/2 per cent of sulphuric acid.  This bath is at 38 DEG  C. and the time of treatment is 18 hours.  After washing and centrifuging, the fibres are soaked in sodium cetyl sulphate and their residual acidity removed in a large excess of 0.5 per cent sodium carbonate solution.  After a further washing and centrifuging, the fibres are dried at 40 DEG  C. in a current of air. Specifications 513,910 and 543,586 are referred to.
