Title: Process for the resolution of an amino-diol racemate
Filed: 1950-12-13
Abstract: Racemic threo 1 - p - nitrophenyl - 2 - dichloracetylaminopropane - 1 : 3 - diol (racemic chloramphenicol) is resolved by forming its acid monosuccinyl derivative (e.g. by heating it with a substantially equimolecular proportion of succinic anhydride in a mutual solvent such as dioxane and adding an organic base such as pyridine), reacting this derivative with strychnine and fractionally crystallizing the resulting mixture of strychnine salts from an organic solvent. The isomer corresponding to the "natural" chloramphenicol from Streptomyces Venezuelae may be regenerated from the more soluble strychnine salt, obtained by evaporating the mother liquor, by treating it with alkali and then with acid to liberate the acid monosuccinate, and hydrolysing this with alkali (e.g. dilute caustic soda) in the cold (preferably at about 0 DEG  C.).  The product may be further purified by recrystallization, e.g. from ethyl acetate, whereby a racemic product first separates, after which traces of the undesired optical antipode may be precipitated by the addition of a mixture of ethyl acetate and petroleum ether and the desired isomer crystallized in a pure form from the mother liquor. If desired, the less soluble strychnine salt may be similarly treated.  In examples, the following solvents are used for the resolution: (1) and (3) a mixture of acetone and chloroform; (2) n-propyl alcohol; (4) acetone (the strychnine salts having been first prepared in a mixture of isopropyl alcohol and chloroform and these solvents evaporated under reduced pressure).

Filed: 1969-06-18
Abstract: 1284273 Slack adjusters GIRLING Ltd 4 June 1970 [18 June 1969] 30748/69 Heading F2E An automatic slack adjuster for a vehicle brake comprises first and second screw elements 10, 21 having a reversible screw-thread connection therebetween and being disposed between first and second members movable relative to one another on brake application, the screw elements being urged in an axial direction relatively to one another responsively to excess travel between the said members to cause one of the screw elements to be screwed along the other of the screw elements and thereby reduce brake slack, the second screw element 21 being non - rotatable and the first member being normally non-rotating; friction surfaces are associated with the screw element 10 and the first member so as to be urged into abutment with one another by the brake thrust to inhibit rotation of the first screw element whereby the relative advance of the screw elements can only take place during take-up of slack. As shown, an hydraulic actuator for a disc brake comprises opposed pistons 10, 11, the piston 10 acting direotly on the pad 14 which co - operates with one face of the disc and the piston 11 acting on a yoke 15 slidably mounted in a body member 13 and acting on a pad co-operable with the other face of the disc. An auxiliary mechanical actuator fitted to piston 11 comprises a cam 16 acting through a dolly 17 and plunger 18 and upon the adjuster 19. The latter comprises a nut 20 secured to the piston 10 and rod 21 in abutment with the plunger 18 or formed integrally therewith, a ring 24 being locked in a groove in the rod and the rod being prevented from turning by a tab 25 extending into a bore 26. A spring 27 comprising a stack of Bellville washers acts to hold the rod against plunger 18. Hydraulic fluid applied between the pistons bring the brake pads into engagement with the disc the normal running clearance being provided by axial displacement of the screw connection 22. A clearance develops between the piston face 30, acting as a friction surface, and the pad back plate 31, also acting as a friction surface, since the spring 27 retracts the piston 10 and in the next brake application the clearance at the screw connection is taken up before thrust is transmitted to the pads. The piston 10 is free to rotate on the screw thread as the clearance is taken up so that when the pads abut the disc a thrust is transmitted to the piston face 30 and the frictional torque developed prevents further rotation of the piston. In a modification, an auxiliary piston forming the nut is slidable in the bore of the piston 10 and the pistons have co-operable frusto-conical friction surfaces.

Title: Improvements in and relating to the production of mica splittings
Inventor: PARSONS AUBREY LACEY
IPC: C04B20/06
Filed: 1953-11-10
Abstract: Mica splittings are obtained by heating mica to a temperature sufficient to remove the water of a constitution, mixing the heated mica with a cold combustible liquid whereby said liquid is absorbed along the clearage planes of the mica, and subjecting the mica so treated to a second heat treatment which results at least partly from combustion of the said liquid to vaporize the absorbed liquid to promote a clearage of the mica into thin flakes. Alternatively the second heat treatment is effected in an inert atmosphere, the combustible liquid being a volatile hydrocarbon which vaporizes rapidly without leaving a carbon deposit on the mica.  Muscovite mica is heated to 800 DEG C., or phlogopite mica to 1100 DEG C., for 20 to 40 minutes, and when still hot is plunged into paraffin or other combustible mineral oil.  The treated mica is then heated to cause rapid vaporization of the oil to split the mica into thin flakes. When the heating is effected in air the oil burns, and decarbonization of the mica is necessary at about 400 DEG C.  Whilst still hot the mica flakes are dropped into water to produce a suspension suitable for the manufacture of insulating material. Alternatively the paraffin oil is vaporized in an inert atmosphere of nitrogen to render decarbonization unnecessary.

Abstract: 603,986. Extruding. BRITISH INSULATED CALLENDERS CABLES, Ltd., HILL, H., and BECKINSALE, S. Nov. 20, 1945, No. 31132. [Class 83 (iv)] In an extrusion press for lead and lead alloys comprising a relatively movable ram and container, the latter having a vertically disposed cylindrical bore open at the top, the ram has a small continuous taper extending from the rear to the front end which enters the container and the larger end of the ram has only a small clearance in the bore of the container. In a specific example, the container bore has a diameter of 12 inches, the total length of the tapering portion of the ram is 25 inches and the ram tapers from a diameter of 11.975 inches to a diameter of 11.725 inches at its lower end. As the ram 3 and container 1 begin to separate after an extrusion stroke, the ram comes away from the surface of the lead layer 16, lining the inner wall of the container, at all points so that there is no production of a vacuum behind the ram and no dragging of the ram over the surface of the lead layer, which, in the case of a cylindrical ram may lead to a ragged surface having enclosed air in the form of blisters. During the extrusion stroke, some of the lead escapes around the ram as at 18, thus expelling the lead most likely to be contaminated by oxide and other impurities.
