Title: Process for the preparation of nonaqueous dispersions of film- forming polymers
IPC: C08F2/00
Filed: 1971-11-19
Abstract: 1328009 Thermosetting polymer composition FORD MOTOR CO Ltd 19 Nov 1971 [1 March 1971] 53925/71 Heading C3P A non-aqueous dispersion of a film-forming polymer is prepared by copolymerizing (a) a monomer containing an epoxide, hydroxyl or amino group with (b) at least one monomer not containing such a group to form a second copolymer having no methylolated amide groups, in the presence of a first copolymer, which is a methylolated or alkoxymethylated copolymer of an amide of an unsaturated carboxylic acid with at least one other monomer, in a liquid medium in which the second copolymer is insoluble and the first is soluble. Preferably the first copolymer is prepared and methylolated in a suitable solvent, e.g. an aromatic or alcoholic compound, then a major proportion of a non- solvent such as naphtha is added before the second polymerization. The dispersion may be coated on to a substrate, dried and cured by heating to cause reaction between the active groups of the two polymers; curing may be accelerated by adding an organic metal salt or by incorporating up to 5% by weight of a carboxyl-containing monomer is one or both of the polymers. Additional polymers, such as alkylated melaime-formaldehyde resins, may also be added to the dispersion. In examples the first copolymer is obtained by reacting a 2-ethylhexyl acrylate/acrylamide/acrylic acid copolymer with formaldehyde and butanol and the second copolymer is derived from styrene, butyl methacrylate, methyl methacrylate, acrylonitrile, acrylic acid, and hydroxypropyl methacrylate or 2,3-epoxypropyl methacrylate.

Abstract: 1,144,237. Secondary fuel cells. SIEMENS A.G. 2 Dec., 1966 [26 March, 1966]. No. 54188/66. Heading H1B. [Also in Division G7] A secondary fuel cell has a two-sided hydrogen electrode with on one side an oxygen anode comprising nickel and on the other side an oxygen cathode comprising silver. While the silver-containing oxygen cathode must be disconnected during the electrolysis operation (recharging) the two oxygen electrodes can be connected in parallel during the recombination reaction (discharging). A parallel connected battery can be formed by having each oxygen electrode two-sided and common to two cells (Fig. 2, not shown), and a series-connected battery has two-sided electrodes with the operating layers supported by a common,  porous and electrically insulating diaphragm  (Fig. 3, not shown). As shown in Fig. 4 the cell has a nickel-containing oxygen anode 41, a hydrogen electrode 45, a silver-containing oxygen cathode 47 and diaphragms 46. The end diaphragms 46 are protected by porous end layers 42. Electrolyte is circulated by pump 48, passing through the cell from end space 44 to end space 43. Part of the gases produced in the electrolysis can be used in a conventional fuel cell.

Title: Calculating machines

Filed: 1970-12-04
Abstract: 1335057 "¢" key arrangements RICOH KK 4 Dec 1970 [13 Dec 1969 (2)] 57595/70 Heading G4B  In a reduced keyboard calculating machine, wherein a pin carriage is laterally shifted through one step after each digit of a number has been entered into the pin carriage, depression of any one of a number of function keys is normally arranged to shift the carriage (storing the set-up number) through one extra step, but such shifting through the extra step is prevented if a "¢" key has been depressed in entering the number. Two alternative mechanisms for controlling the extra step shift are described, the first, Fig. 5, being electro-mechanical, and the second, Fig. 3 (not shown), being generally similar but wholly mechanical. When a number not including "¢" has been set up in the pin carriage 3, Fig. 5, and a function key is depressed, a plate 14 moves upwardly (as shown in Fig. 5) to close a switch 34 and energize a solenoid 35. The solenoid plunger 35A rocks a lever 16 anti-clockwise, which rocks a lever 19 clockwise to raise a plate 22. Plate 22 shifts the zero pin in carriage 3 and the latter shifts one step to the left. Towards the end of its clockwise rocking, lever 19 engages a lug 26B to rock a lever 26, the right hand end of which depresses a lug 27A to rock a lever 27. This disengages a lug 27B from a lug 17B to allow a spring 29 to move a slide 17 to the right. Slide 17 carries the pivot 18 of lever 16 which is thus also moved to the right and disengaged from both plunger 35A and lever 19. A spring 43 then restores lever 19 and plate 22. If the "¢" key is depressed as the last step in setting up a number, a plate 23 is raised and, through a pin 24, rocks lever 26. As above described, this renders solenoid 35 non-effective so that a subsequent depression of a function key will not result in the pin carriage 3 shifting through the extra step. When lever 26 is rocked, either by lever 19 when the pin carriage is being shifted through the extra step or by pin 24 when the "¢" key is being depressed, a shoulder 26C clears a pin 38 to allow leftward movement of a plate 37 whereupon lug 37A engages a step 40A of a plate 40. This prevents upward movement of the plate 40 and prevents depression of the keys corresponding to digits "1" to "9". The "¢" key is linked to the "5" key so that on depressing the former, the "5" pin is set in the pin carriage, Fig. 4 (not shown).

[Classes 1 (i) and 91] Emulsions of the oil-in-water type, suitable as cooling lubricants for metal-cutting tools or for other purposes, are obtained by treating an oily material having an acid value of not less than 70, firstly with aqueous alkali containing only a part of the alkali necessary for the neutralization of the free acids contained in the material at a temperature of substantially 100 to 110C., then by the addition of water which may contain di-sodium phosphate, and finally with aqueous alkali containing the rest of the total quantity of alkali necessary to complete the neutralization of the free acids at a temperature of substantially 50 to 55C. The process should preferably be so conducted that the final pH of the product is between 8 and 9, say 8.5 Potassium hydroxide is the preferred alkali, but sodium or ammonium hydroxides may be used.
