Abstract: 132,382. Hopkins, G. T., and Marshall, W. Oct. 15, 1918. Inserting wire and like metal nails.-A machine for driving nails, tacks &c. comprises a hopper 17 for the loose nails &c. co-operating with an adjustable rotatable truncated cone 10. The stems of the nails passing into an annular space between the two, and the heads being supported by a ledge 16. The nails slide in single file between adjustable plates 23 to a notched separator oscillated by a handle 31, which also oscillates a member 35 having a recess 34 which receives one nail at a time from the separator. A driver 41 is raised by a pinion 43 gearing with a rack 42 and carried by a drum 45 in which is a spring. A handle 46 contacts with a stop 47, raises the rack, and compresses the spring until the handle is forced away from the stop 47 by a fixed cam 48. The spring then causes the freed drum 45 to drive the rack and driver 41 downwards on to a nail which was fed into a guide 38 when the driver was raised. A handle 20 enables the operator to steady the machine. The driving-mechanism is adjustable about a shaft 32 for varying the angle at which the nails &c. are driven into the work, and is clamped in adjusted position by a wing-screw 53. A gauge 56 may be provided. According to the Provisional Specification, the hopper 17 may have a shutter for feeding the tacks into the space between the hopper and the cone; the driver 41 is depressed by hand and may be returned by a spring; rollers on the gauge 56 may release tacks at spaced intervals: and the cone 10 may be rotated automatically, e.g. by gearing from the rollers.

Title: Improvements relating to separators for electric accumulators
IPC: H01M50/42
Filed: 1943-10-14
Abstract: A separator for battery electrodes is formed of a fabric woven or knitted from threads of molecularly orientated synthetic resin, the threads being shrunk after fabrication by heating the fabric to a high temperature, but not high enough to cause the resin to become tacky, whereby the separator is made rigid but flexible. The fabric may be knitted with needles omitted in contiguous rows as shown at 15 in Fig. 2, so as to become ribbed when shrunk, as shown at 15a in Fig. 4.  The <PICT:0570894/IV/1> <PICT:0570894/IV/2> separators may be included in the battery in the form of sheets separate from the plates or the separator may be formed as a sleeve and slipped over the plate and shrunk thereon.  Suitable resins are resins of the CH2 = C< type, such as solid polymerized vinyl esters like polyvinyl chloride, polyvinyl acetate and their copolymers; the acrylic resins, for example, polymerized methyl-methacrylate and ethylmethacrylate and polystyrene.

Title: Method for Producing Coke
IPC: C10B53/08
Filed: 1968-04-08
Abstract: 1,194,962. Making metallurgical coke. GREAT LAKES CARBON CORP. 8 April, 1968 [12 April, 1967], No. 16884/68. Heading C5E. Metallurgical coke is made by a two-stage heating process with intermediate pressing and shaping similar to that described in Specification 1,119,869, but the particulate material is mixed with a plasticizing agent which is neither vaporizable nor decomposable below 490 F., e.g. the furfural extract of heavy lubricating oils, asphalt, anthracene oil, coal tar, thermal tar, and pitch (petroleum or coal tar) in amounts of 1 to 8% b.w. of the particulate material. This enables lower temperatures to be employed in the first stage, namely, from 300 F. upwards to one below the fusion temperature of the particles. Fusible coal may be used alone, i.e. without coke, as the particulate material, and the optional inert material includes oxidized raw petroleum coke and ores. The particulate material and the plasticizer may be separately heated before mixing (see Figs. 1 and 2, not shown), or mixed before being heated (see Fig. 3, not shown). Volatile matter contents (by weight) of the particulate materials are: coal alone, 15 to 20%; coal with coke, 15 to 45%; coke alone (excluding water) 10 to 20%; coke with coal, 8 to 20%. Heating in the first stage may be rapid, e.g. 1 second where a coal/coke mix is employed, and carbonization of the shaped bodies is preferably effected within 8 hours. The pressing stage produces a shaped body having an apparent density of at least 0À85 g/c.c. and a porosity not greater than 37%.

Abstract: 1492102 Polymers containing uretdione groups BAYER AG 24 April 1975 [27 April 1974] 17005/75 Heading C3R A process for the preparation of uretdione group-containing polymers comprises the reaction of (a) at least one uretdione group-containing polyisocyanate, e.g. dimeric tolylene diisocyanate, or a mixture of at least one uretdione group-containing polyisocyanate and at least one uretdione group free diisocyanate, e.g. monomeric tolylene diisocyanate, with (b) at least one active hydrogen-containing compound which is either water or an aliphatic or cycloaliphatic compound having a mol. wt. below 300 and containing two groups selected from amino, thiol, carboxyl and hydroxy groups, e.g. hexane-1,6- diol together with from 0 to 60% by weight based on the total weight of active hydrogencontaining compounds, of an aliphatic or cycloaliphatic compound having a mol. wt. below 300 and containing an amino, thiol., carboxyl or hydroxyl group, e.g. glycol monoethyl ether, the compounds (a) and (b) being reacted together in an overall NCO/active hydrogen ratio of from 1 : 1 to 1 : 6 and in such proportions that the products of the process contain from 0 to 2 amino, thiol, carboxyl or hydroxy end groups per molecule and from 2 to 20% by weight of latent -NCO groups, i.e. -NCO groups formed bythermal decomposition of uretdione groups and which are unable to find end groups to react with and are therefore available for crosslinking reactions. The reaction may be carried out at a temperature between 0 and 150 C. optionally in an inert solvent e.g. toluene and optionally in the presence of a catalyst, e.g. dibutyl tin dilaurate. The uretdione group containing polymers which may be obtained from the reaction mixture as fine, free flowing powders, have mol. wts. of 800 to 5,000, melting points of from 30 to 240 C. and have no free -NCO groups. These polymers may be used as crosslinking components in powder lacquer compositions which contain in addition 5 to 85% by weight based on the total weight of crosslinking component, of a polyhydroxy compound, e.g. a polyester or polyether. The components of the lacquer do not react under normal storage conditions but when applied to a surface e.g. by an electrostatic spray device and the powder then melted and stoved the uretdione rings open forming -NCO groups which crosslink the polyhydroxy compound forming a coherent film.
Patent GB-219322-A (GB)
IPC: C10G7/00
Filed: 1924-07-16
Abstract: Hydrocarbon oils, such as petroleum, shale oil, lignite or coal tar oils, are purified by distilling them and collecting the distillate in fractions within narrow limits so that all the impurities, such as furane and its homologues and pyrrole and its homologues, are contained in one or more of the narrow fractions. In distilling benzine obtained by destructive distillation of brown coal, it is found that the colouring and resin-forming constituents are contained in the fractions distilling over at 62 DEG  C., 86 DEG  C. and 108 DEG  C.  The benzine is purified therefore, by distilling in an apparatus provided with an efficient dephlegmator and removing these fractions.  The distillation may be carried out wholly or in part under reduced pressure, and fractions separated under ordinary pressure may be subsequently distilled under reduced pressure.  The hydrocarbon may be first separated into fractions over wider limits and the separate fractions be subjected to a further fractional distillation.
