Title: Microporous sheet and method for preparing same
IPC: H01M50/429
Filed: 1967-05-03
Abstract: 1,148,852. Microporous coated sheet material. W. R. GRACE & CO. 3 May, 1967. [3 May, 1966], No. 20615/67. Heading B2E. A micro porous sheet is prepared by forming on a permeable substrate a micro porous layer of thermoplastic polymer by depositing on the substrate relatively large particles of a thermoplastic polymer and thereafter relatively small particles of a thermoplastic polymer, the small particles having a diameter less than two microns and the large particles having a diameter at least seven times the average diameter of the small particles; sintering the polymer particles either in one stage after both the large and the small particles have been deposited, or in two stages, one stage after the large particles have been deposited and one stage after the small particles have been deposited. The small particles may be from 0.01 to two microns diameter. The large particles may have an average diameter at least 40 times the average diameter of the small particles and may have a diameter of from 15 to 70 microns. The large particles may be deposited in two steps, particle 20 to 170 microns in diameter being deposited in the first step and particles 15  to 70 microns in diameter being deposited in the second step. The particles deposited in the first step may be sintered before the second step. The large particles may be deposited by knife coating, air knife coating, falling curtain coating, fog deposition or by electrostatic deposition. The small particles may be hydraulically deposited from a fog of the particles. The small particles may be deposited with the aid of reduced pressure on the side of the substrate opposite the particles. The large or the small particles or both may be composed of polymers or copolymers of vinyl chlorine, vinylidene chloride, acrylonitrile, acrylates, e.g. vinyl chloridevinyl acetate copolymer. The large or the small particles or both may have been prepared by emulsion or suspension polymerization. The substrate may be a glass mat, a mat of synthetic fibres or a cellulosic sheet which may be impregnated with a phenolformaldehyde resin and may have an average pore aperture of 30 to 35 microns. At least 90% of the pore apertures of the micro porous layer may be from 0.5 to 5 microns in diameter. The micro porous layer may be formed on both 'sides of the permeable substrate. The permeable substrate may be removed from the said microporous layer after the latter has been formed. The micro porous sheet may be used to separate electrodes in a battery.

Title: Process for preparing cyclene-carboxylates
Inventor: BONNET YANNIK
IPC: C07C69/74
Filed: 1966-05-10
Abstract: The invention comprises compounds of the formula <FORM:1079100/C2/1> where R and R1 are alkyl of 1-4 carbon atoms, or R1 is H, and A is an alkylene radical of 4-11 carbon atoms.  The compounds are prepared by reacting a compound of the formula <FORM:1079100/C2/2> where X is a halogen, with an alkali metal alkoxide of 1-4 carbon atoms in an anhydrous alkanol and, if desired, saponifying the ester formed with an alkaline base.  The trihalogenated compound may be prepared by the action of halogen on the corresponding cycloalkanone. The hydroxy-acid may be decarboxylated by heating in an inert atmosphere, e.g. nitrogen, to give the cycloalkenol. The cycloalkenol may then be hydrolysed to a cycloalkenone, e.g. by a strong acid in an aqueous organic medium. Missing Page 128

Title: Improvements in or relating to two axle bogie railway vehicles
IPC: B61F5/16
Filed: 1933-07-31
Abstract: 427,884. Railway - vehicle bogies. LIECHTY, H., and LIECHTY, R., 24, Weststrasse, Berne, Switzerland. July 31, 1933,. No. 21438. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 31, 1934.] [Class 103 (vi)] In order substantially to equalize the load on all the wheels of a two-axle railway vehicle bogie, the underframe 10 is supported by a transverse load distributing or spring system comprising laminated springs 7 bearing upon an intermediate member or bolster 6 which in turn is rotatably supported on a transverse member 4, the ends of which are pivotally mounted centrally of the side members 1 of the truck frame so as thereby to equalize longitudinally the load transmitted to the axles 2, 2<1>. The truck frame 1 is itself mounted by springs 13 on seats suspended from longitudinal bars 3, the ends of which rest on the axle-boxes. The bolster 6 is prevented, by means of plates 11 on the underframe entering slots in the bolster, from rotating relative to the underframe, but is capable of swivelling on the member 4 through the medium of a turntable 5, while springs 9 are disposed between the ends of the bolster and the underframe to give lateral stability to the body, without affecting to a great degree the load equalization. A pivot pin 8 on the underframe passes through a ball member 15 movable universally in the member 4. In a modification the ends of the transverse member 4 are journalled in supporting elements which are mounted on the bogie frame by transversely disposed laminated springs. In this case the upper leaf springs 7 are dispensed with and the bolster 6 is constrained to move with the underframe by means of depending pins on the underframe engaging apertures in the bolster.
