Abstract: 1,215,415. Films of ion-exchange resins. RHONE-POULENC S.A. 18 March, 1969 [19 March, 1968], No. 14301/69. Heading B5B. [Also in Division C3] Films are prepared from ion-exchange resins consisting of units of formula alone or with units of formula where radicals R are m- or p-phenylene or p-diphenylene, n is 0 or 1, R<SP>1</SP> and R<SP>3</SP> are hydrogen atoms or aliphatic or cycloaliphatic radicals or, when n is 0, together form a polymethylene chain, and R<SP>2</SP> is a radical of formula where M is a transition metal and p is the degree of oxidation of the metal, the units having ion-exchange groups attached thereto and optionally being cross-linked. The resins are obtained by first condensing a dialdehyde of formula with a ketone of formula optionally cross-linking, e.g. by reaction with divinylbenzene or with a tetravinylsiloxane, and then introducing ion-exchange groups into the resins. Cation-exchange groups which may be introduced are sulphonic, carboxylic, phosphinic, phosphonic and arsonic groups, and anionic-exchange groups which may be introduced are amine, quaternary ammonium, phosphonium, sulphonium and sulphonamide groups. In examples, films are prepared from polycondensates of terephthaldehyde and acetone and converted to ion-exchange resins by sulphonation with chlorosulphuric acid, by chloromethylation with methoxychloromethane, followed by quaternization with trimethylamine, and by reaction with p-dimethylaminobenzaldehyde to attach amine groups to the chain ends followed by quaternizing coupling with p-bis (chloromethyl) benzene; two of the films are cross-linked with tetravinylcyclotetrasiloxane before being converted to ionexchange resins.

Title: Improved Apparatus for Governing Centrifugal Compressors.
IPC: F04D27/02
Filed: 1917-10-16
Abstract: 113,950. Akt.-Ges. Brown, Boveri, et Cie. March 5, 1917, [Convention date]. Fluid governors.-A motor driving a centrifugal compressor is controlled by a centrifugal governor B and a pressure governor M adapted to regulate independently the size of an escape port for a fluid which passes under a piston K and controls the supply valve E of the motor. The governor B controls a piston the upper edge of which controls the port in a sleeve N controlled by the pressure governor M. The governor M may be adjusted by means of a spring and may be cut out by a valve. In a modification the governor M acts on the sleeve N by means of a lever and hand-gear is provided for adjusting the speed when the governor M is cut out. Instead of governing for constant pressure, governing for constant volume may be effected by inserting a member in the air pipe which operates a distributing device allowing compressed air of varying pressure to act on the piston M.

Title: Improvements in Grinding Machines.
Inventor: MARCH SYDNEY HERBERT
IPC: B24B19/06
Filed: 1917-10-17
Abstract: 112,605. March, S. H., and Asbridge, H. H. Oct. 17, 1917. Disk apparatus.-In a machine for grinding ball races and other annular grooves of part-circular cross-section, the swivelling workcarrying member 10 is supported between trunnion bearings 11, 12, which are at right-angles to the work spindle 15 and form the vertical axis for the swivelling motion. The spindle is mounted in a slide 13, which is adjusted by a screw to the depth of groove required. The grinding-disk 46 is mounted on a compound slide 25, 26, the part 25 having a pin 30, Fig. 4, which is held by a spring 32 against a rotary helix cam 31, and the part 26 being operated by a hand-lever 28 for bringing the disk into grinding position. The cam effects the feed of the disk into the work and is rotated by the engagement of a pawl 36 with an interrupted ratchet-wheel 35, the pawl being operated from the member 10 by the action of a projection 42 upon a lever 43 and arm 44. The cam gives a diminishing feed to the disk until zero is reached, and at this position of the cam the interrupted portion of the ratchet-wheel has come round to the pawl so that the cam cannot be further turned by the action of the pawl. In order to withdraw the disk from the work, the cam is rotated farther by hand until the pin 30 is forced by the spring into a depression in the cam. For giving the disk a further feed than that obtained by the cam, a screw 37 is turned by a worm-wheel 38 and worm 39 to move forwards a non-rotatable nut 40 at the back of the cam.

Abstract: 923,651. Preparing metal alkyls, electrolytically. K. ZIEGLER. April 29, 1960 [May 6, 1959], No. 15151/60. Class 41. Alkyls of the metals Be, Mg, Hg and also of Group III to V are made by fusion electrolysis of a compound MeAlR 3 R<SP>1</SP> where Me is Na or K, R is an alkyl preferably of 2 to 6 C atoms, R<SP>1</SP> is alkyl, alkoxy, aroxy, or fluorine, using a mercury cathode, and as anode the metal of which the alkyl is required. A mixture of K and Na compounds may be used containing up to 80% of the K compound. The following products are specified in examples: lead tetraethyl, aluminium triethyl, magnesium diethyl, indium triethyl, antimony triethyl, tin tetraethyl, thallium triethyl, bismuth triethyl, and mercury diethyl. The starting compounds inelude a mixture of Na and KAl(Et) 4 , sodium aluminium tetra ethyl and sodium decyl-oxyaluminium triethyl, and NaF.2Al(Et) 3 . To this electrolyte may be added A1 tri alkyl derivatives e.g. aluminium trietherates or tri-alkyl amminates, which act as solvents. A suitable apparatus comprises a cell A having a narrow base into which the products of the reaction flow and are cooled to aid separation from the main body of the electrolyte, and are finally drawn off at H. The mercury cathode is contained in a dish-shaped member B, recessed at the centre and having a perforated flange, so that mercury may continuously flow across the reaction zone in close proximity to the anodes, and the amalgam then treated to reduce the sodium content in a separate regeneration stage. A stirrer R assists in keeping the mercury surface free of reaction products. The bottom of the metal anodes is maintained at a few mm. above the mercury surface, by (1) mounting the anodes on screw thread members; (2) resting the anodes on glass supports projecting upwards from the mercury layer, or by mounting a series of the metal plates or blocks on hangers which run down a slightly inclined overhead rail, new plates being added at the higher entry end of the rail system. All these forms are illustrated: The electrolysis is effected in vacuo, at 100 to 160 C., C.D. up to 100 A.S. Decimetre, and at 1 to 5 volts. The metal alkyl may be separated from the Al(Et) 3  and other products by extraction, vacuum distillation, or by forming another product of higher B.Pt. by interaction with an added compound as described in Specification 864,394. The aluminium alkyl products may be treated with ethylene and hydrogen to reform the starting electrolyte. The mercury amalgam is regenerated in a secondary electrolysis process using the sodium aluminium alkyl complex as electrolyte, the amalgam forming a bottom layer as anode, at the surface of which is a mesh of cellulose or glass fibre fabric which holds the sodium produced in suspension as a third layer below the cathode suspended in the molten electrolyte. Specifications 763,824, 841,609, 848,364 and 864,393 also are referred to.
