Title: Process for producing bound aggregate building material
IPC: C08L71/14
Filed: 1972-02-02
Abstract: 1364341 Building material composition QUAKER OATS CO 2 Feb 1972 [3 Feb 1971] 4964/72 Heading C1H [Also in Division C3] An impermeable bound aggregate building material is produced by mixing monomeric furfuryl alcohol (99À5-99À875 wt. per cent) and a silane coupling agent (0À5-0À125 wt. per cent), forming a second mixture of aggregate (e.g. sand) and acidic catalyst, mixing 2À20 wt. per cent. of first mixture with 98-80 wt. per cent of the second mixture and admixing with this resultant mixture 1-30 wt. per cent clay. In a modification 2-10 wt. per cent of the first mixture is replaced by an aqueous ureaformaldehyde mixture containing 5-25 wt. per cent water. The silane is of the general formula X-R<1>-Si-(OR<11>)3, R<1> being CnH2n, n = 3-6, R<11> = aryl, substituted aryl, alkyl or heteroalkyl and X = amino, mercapto, epoxy or glycidoxy. Examples of silane agents are listed. The acid catalyst, polymerizing the furfuryl alcohol to a resin (e.g. toluene sulphonic acid, phosphoric acid, ammonium chloride, ammonium trichloroacetate, ammonium phosphate, ammonium sulphate and ammonium nitrate) is present in an amount of from 5% to 50% by weight of the monomeric binder. The clay is not so basic that it will react substantially with the acidic catalyst.

Filed: 1946-02-18
Abstract: Vinyl ethers are polymerized at temperatures between -10 DEG  C and -100 DEG  C. using an acid-reacting catalyst in a solvent-diluent comprising a normally gaseous aliphatic hydrocarbon having a melting-point below the reaction temperature and having at a temperature below its boiling point, a selective solvent action for the low molecular weight polymers formed and isolating, e.g. by filtration or dipping out, the high molecular weight polymers from the solution at a temperature below the boiling-point of the solvent-diluent.  Copolymers of two or more vinyl ethers or of a vinyl ether with isobutylene or butadiene may be similarly prepared. There are specified: vinyl esters-vinyl methyl, vinyl ethyl, vinyl propyl, vinyl isopropyl, vinyl n-butyl, vinyl isobutyl, vinyl hexyl and vinyl octyl ethers; catalysts-tin tetrachloride, stannous chloride, aluminium chloride, iron chloride, zinc chloride, sulphuric acid, hydrochloric acid, sulphur dioxide, boron trifluoride and its complexes with diethyl, dipropyl, ethyl methyl, dibutyl and diamyl ethers; solvent-diluents-ethylene, ethane, propane, butane.  The reactants are preferably pre-cooled and addition of one or the other is preferably portionwise.  The process may be carried out continuously.  The catalyst may be deactivated by addition of sodium, potassium or ammonium hydroxides, methanol, ethanol, butanol, methylamine, diethylamine, ethanolamine, diethanolamine, pyridine, acetone, methylethylketone or acetaldehyde and removed by washing with aqueous alkali.  The high molecular weight polymers may be compounded with stabilizers, pigments, &c. to form a rubber substitute.  Specification 378,544 is referred to.

Filed: 1927-02-26
Abstract: 291,497. Hemmingsen, T. V. Feb. 26, 1927. Cylinders receiving liquid fuel.-To ensure an adequate supply of fuel during the initial injection stage the first portion of the fuel is delivered by a pump or its equivalent the remainder is injected by the action of compressed air. The injector shown in Fig. 1 has an admission valve 6 with a spindle 7 carrying a sleeve 8 which serves as a plunger to force oil from an annulus 10 through passages 21, 23 and directly into the cylinder immediately the valve opens. During the period when the valve is seated, fuel is deposited in a pocket 29 by a pump 17 which delivers through passages 18, 21 and an annulus 24 opening into the pocket; the fuel is subsequently conveyed to the cylinder by compressed air admitted through a port 12 and traversing a gap 13 and passage 16, 30 at the spraying point. The injector shown in Fig. 1 is for use in a horizontal position and a modified construction is described for use in a vertical position. The pump 17 may be timed to deliver the initial portion of the fuel which enters the cylinder directly, and also the portion which is deposited in the injector: in this modification the pumping action of the plunger 8 is dispensed with. Also, the fuel injected initially may be supplied by an independent pump or by the pump 17 working in conjunction with a pipe line containing an accumulator or the equivalent.

[Also in Division B3] A self-damping composite metal spring 1 comprises an envelope 2 of circular, rectangular, or flattened cross-section made e.g. of hard spring steel and having an elastic limit or yield strength beyond normal working-load conditions so that it is not permanently distorted and one or more correspondingly-shaped cores 3-6 of a different metal symmetrically as shown, or asymmetrically, arranged within the envelope, the core or cores consisting of a metal, e.g. mild steel or alloy, having an elastic limit or yield strength low enough to be always stressed thereabove under normal load conditions so as to be plastically strained. The cores can be first prepared before the envelope is cast around them. Alternatively the envelope is first gouged or drilled the cores or cores then being force-fitted, or welded, within the holes. In each instance the composite metal rod is subjected to customary operations to impart the desired shape to the spring.
Patent GB-286598-A (GB)
Title: Improvements in automatic firearms having a recoiling barrel and an amplifying push lever
IPC: F41A9/33
Filed: 1928-02-21
Abstract: 286,598. Soc. Italiana E. Breda. March 5, 1927, [Convention date]. Machine guns.-Relates to machine guns having a short barrel-recoil breech action, the recoil of the barrel being transmitted to the breechblock by an " amplifying " lever. According to the invention, this lever is so arranged that it maintains permanent contact with its operating faces. As shown, the barrel 2, Fig. 1, is attached to a breech body 8 connected to a carriage 15, the face 38 of which bears against the upper arm of the amplifying lever 14, while the curved surfaces 39 of the carriage maintain contact with a roller 36 at the end of the lower arm of the lever. The breech-bolt 7, thrust back by the lever 14, compresses the main recoil spring 12 and is stopped by a spring buffer 13. The recoil spring 12 may be adjusted by means of an end screw plug 16. The bolt 7 is locked in the closed position by a key 17, Fig. 3, sliding transversely in the breech-body and operated by a cam groove in a member 18 in the breech casing 1 during the recoil and run out of the barrel. This locking device is situated near the front end of the bolt and at one side, to leave a free space for the ejection of the spent cartridges downwards. The Specification as open to inspection under Sect. 91 (3) (a) describes also the following further features : The firing pin 11 is situated in the bolt, but the hammer 27, Fig. 13 (Cancelled), therefor is in a casing 19 at the side of the breech casing. This hammer is cocked against a spring plunger 30 during the recoil, and is held cocked by a detent 28, which is pulled by a lever 29 when this is deflected by the closing of the breech. When the gun is used on an aircraft, the fire is controlled by the propeller shaft, which is connected by suitable mechanism to a detent 45 adapted to hold the hammer after its release by the detent 28 until the proper moment determined by the propeller shaft. The cartridges are supplied by a belt fed through a transverse way 3 above the breech-body by a lever 5 worked by the breech-bolt (as described in Specification 305,595), through a winglike arm 6 pivoted on a long spindle 41 and provided with a tooth 42 engaging a cam on the breech-bolt, which, with the breech-body, is made of cylindrical shape. During the opening of the breech, a cartridge is extracted from the belt by a double-sided gripper 23, and is then moved down by a vertically sliding pillar 9 operated by a cam in the side of the breech casing. The fresh cartridge takes the place of the ejected cartridge in a gripper in the front of the bolt 7, and is held there by a spring lever while the breech closes. These cartridge feeding and ejecting devices are described in Specification 305,595. This subject-matter does not appear in the Specification as accepted.
