Title: Improvements in or relating to the treatment of sea-slime and like slimy material toenable it to be transported
IPC: C05F7/00
Filed: 1938-04-23
Abstract: 508,127. Manures.WEBER, O.. April 23, 1938, No. 12255. [Class 111] A readily-transportable fertilizer is obtained from sea-slime or like slime-like masses which form in riverestuaries, rivers, seas and ponds by dehydrating the slime into a pulp which is still' sufficiently thin to flow and thereafter mixing it with such quantities of non or slightly absorptive and finely grained substances, that a loose mixture is obtained which is easily penetrable by air. The dehydration may be effected by centrifuging in separators. Suitable non or slightlyabsorptive materials include sand, ground rocks such as granite basaltic rock &c., ground Thomas slag and dried and pulverized mud obtained by drying fresh slime. The product should be transported in such a way as to allow free access of air.

Title: Impact tool
IPC: F02B71/04
Filed: 1959-04-10
Abstract: 914,055. Percussion tools. OMARK INDUSTRIES Inc. April 10, 1959 [April 11, 1958], No. 12260/59. Class 124. An impact tool comprises a piston reciprocable in a cylinder, means urging the piston to one end of the cylinder, a second means to move the piston from the one end to an intermediate position in the cylinder, a lock for the second means, a manual control to unlock the second means, means to introduce a charge of fuel and air during movement of the piston to the intermediate position, and means to fire the charge to produce an impact. As shown, a cylinder 22 has a piston 28 sliding therein and urged towards one end by a spring 36 surrounding a piston-rod 32 which carries an extension 46 supported in a guide 26. A piston 56 urged towards the piston 28 by a spring 62 is held in a retracted position by a latch 76 engaging a locking member 74 which may be released by a trigger 82. Movement of the trigger 82 causes fuel from a pump to be ejected on to a valve 202 and a supporting spider 194; at the same time the piston 56 moves the piston 28 to an intermediate position, the suction created by this movement opening the valve 202 and admitting a mixture of fuel and air into the chamber formed between the piston 28 and the end of the cylinder. A spark plug 252, energized by a contact operated by a cam follower 238, ignites the mixture. The explosion drives the piston 28 forwards to produce a blow and the piston 56 backwards where it is again held by the latch. The amount of fuel ejected may be adjusted by a screw 184 and knurled nut 180 altering the position of the trigger and so the travel of the pump plunger. The tool may be used to drive nails or lop branches off trees.

IPC: C14B1/00
Filed: 1945-05-16
Abstract: <PICT:0590986/IV/1> Washing, bleaching, dyeing, waterproofing, and drying of textile materials are effected by circulating the appropriate temperature-controlled reagent parallel to the planes of the textiles stacked in a hermetically-sealed chamber, causing different parts of the peripheries of the textiles to be presented to the flow of reagent, and subjecting the textiles to continuous flexure in a direction transverse to the reagent flow.  The reagent passes from a header tank 24, supplied from mixing and water tanks, to a chamber 21 in which the textiles are arranged horizontally on a resilient bed 72 in a perforated basket 70 which is rotated by a motor 77.  The cover 56 of the chamber is operated by a motor 59 and a motor-driven movable wall 61 incorporates reciprocating rams 65. Reagent is circulated through the chamber by a reversible pump 81 via lines 52 and 54, or 84 and 85, and the pressure in the chamber is controlled by reducing and safety valves.  A drain from the bottom of the chamber may lead to a filter and a fat separator.  The line 106 may be connected to an air pump for supplying compressed air to the chamber or for creating a vacuum therein.  Quantity meters, pH indicators, thermometers, and pressure indicators in the tanks and chambers, and flow-meters and thermostatically-controlled heaters in the pipe lines may be connected electrically to a control panel, and the valves, pumps, and motors may be automatically operated in a predetermined sequence.  In modifications of the apparatus (Figs. 5-9, not shown), (1) the rams are in the sides of the chamber, with the textiles stacked vertically, and a vertical flow of reagent; (2) a cam disc, associated with the rotating mechanism for the basket, reciprocates a platen under the resilient bed, and annular cams on the cover of the chamber operate the rams.

Title: Improvements in or relating to the production of ether-esters of substituted aliphatic acids
Filed: 1940-08-05
Abstract: 543,029. Ether-esters. DU PONT DE NEMOURS & CO., E. I. Aug. 5, 1940, No. 12581. Convention date, Aug. 5, 1939. [Class 2 (iii)] Ether esters of substituted aliphatic acids are produced by re-acting in the presence of an acid catalyst an α-hydroxy aliphatic acid or an ester or anhydride thereof with an ether ROR<SP>1</SP> where Rand R<SP>1</SP> are similar or dissimilar alkyl, aryl, aralkyl, heterocyclic or alicyclic groups, or ROC n H 2n OR<SP>1</SP> where, n is greater than one and Rand. R<SP>1</SP> are similar or dis-similar alkyl or aryl groups. Instead of the substituted aliphatic acid there may be used formaldehyde and carbon monoxide. Suitable aliphatic acid compounds are glycollic acid alkyl esters, glycollides polyglycollides and other anhydrides of glycollic acid and lactic acid esters and anhydrides. Suitable acid catalysts are sulpburic, hydrochloric and phosphoric acids, alkali acid sulphates, boron fluoride and chloride, oxalic and malonic acids and their acid salts. When boron fluoride is used it may be first combined with the ether. Boron fluoride compounds with water, methanol, methyl methoxy-acetate, glycollide and the like may also be used. Boron fluoride may be displaced from an alkoxy-acetate product by adding calcium fluoride. In examples (1) partially dehydrated glycollic acid is re-acted with dimethyl ether and boron fluoride dihydrate ; (2) methyl glycollate is re-acted with dimethyl ether and sulphuric acid ; (3) methyl glycollate is re-acted with di-methyl ether and boron fluoride dihydrate ; (4) dimethyl ether is re-acted with paraformaldehyde carbon monoxide and a dimethyl ether boron fluoride complex at 700 atmospheres pressure. The Specification as open to inspection under Sect. 91 includes the use of ethers generally and is not limited to the use of an acid catalyst. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to sole-fitting machines
IPC: A43D43/02
Filed: 1920-05-06
Abstract: 167,551. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). May 6, 1920. Vertical-cutter type for cutting sheet material in direction of feed.-Relates to machines which channel, groove, shoulder, or otherwise operate on the margin of a sole or insole more particularly of the type described in Specification 25730/06, [Class 17, Boots &c.], and consists of an improved variable sole-feed mechanism, and an improved slashing-mechanism. The four-motion mechanism of the feedplate 12 is similar to that described in the abovementioned Specification with the difference that the horizontal component of the motion from the eccentric pin 42 acts positively in one direction and through an interposed spring 45 in the opposite direction. By means of a treadle (not shown) a pivoted bar 25 with an adjusting-pin 48 is swung into the path of a hardened surface 52 on the yoke 25, thus shortening the horizontal travel of the yoke and the feed-plate. The presser foot 10 is slotted to straddle the forward end of the feed-plate 12, which has a projection 57 for preventing curling of the insole on the edge gauge being moved in. For slashing one or both lips in order to facilitate their upward turning, a slotted knife 60 is attached to a pivoted holder 61 with a vertical arm 64 to which is fulcrumed a lever 68, operated by means of a stud 70 on the cam 71 mounted on the main shaft 40. The arm 68 is put into its operative or inoperative position by a forked lever 72 pivoted on the pin 73 and connected to the top end of a shaft 74, Fig. 5. A spring 78 tends to raise the rod 74, which slides in a fixed guide 75 on the machine frame, and a bracket 76 movable with the worktable 8. A curved lever 80 is connected with the rod 74 through a clutch, so that it can move with the bracket 76 relative to the rod normally, but when the lever 80 is swung down on a pin 81 the edge 87 bites the rod and depresses it, a spring 88 maintaining the lever 80 in its horizontal position. A. handle 66 is depressed when the edge gauge 56 is shifted, and the curved lever 80 is situated under the handle 66, so that an extension of the depressing movement also depresses the rod 78 and puts the slashing knife into operation. A chamfering-knife may be fitted.
