Title: A process for synthetic manufacture of acetic acid
IPC: C07C51/235
Filed: 1931-05-29
Abstract: In the production of acetic acid by the oxidation of liquid acetaldehyde, the gas space above the reaction liquor is filled with a non-reactive gas such as nitrogen, carbon dioxide, or when low temperature is employed, air, under pressure, and the oxidation is effected by introducing oxygen under pressure at the bottom of the vessel through a non-return valve.  The pressure employed is higher than that at which the acetaldehyde would boil at the reaction temperature.  A catalyst such as manganese acetate may be employed, and only enough oxygen for the oxidation is admitted.  The reaction vessel may be a long cylinder of aluminium provided with heating, cooling, and agitating devices.  The oxygen employed may be that obtained as a by-product in the manufacture of hydrogen for the synthesis of ammonia, and the nitrogen may be obtained by fractionation of liquid air.  The oxygen supply pipe may be flushed with nitrogen before the process is started.  There is a reference to reaction vessels of aluminium-silicon alloys and of stainless steel.

Title: Method of lithium extraction
Inventor: COLLINS GROVER GERALD
IPC: C22B26/12
Filed: 1955-06-06
Abstract: In the extraction of lithium from silicate ores such as petalite, lepidolite and spodumene, the ore is roasted at 300 to 800 DEG C. with a plurality of reactants, (i.e. two or more different reactants), one being a nitrate or hydroxide of an akali metal, preferably sodium nitrate or hydroxide, and the other reactant or reactant being a carbonate, sulphate, oxide or hydroxide or an alkaline earth metal.  The roasted ore is then leached with an aqueous medium for the recovery of lithium, the pH of the medium preferably being controlled by the addition of sulphuric acid to a pH of 4 to 7 to extract the lithium as sulphate.  The total weight of reactants should be at least equal to the weight of lithia in the ore and may be 10 to 20 times as great, whilst the percentage of the alkali metal nitrate or hydroxide for example may be from 5 to 75 per cent by weight of the total reactants.  A mixture of sodium nitrate and sodium hydroxide in the preferred proportion of 1 part hydroxide to 1 to 6 parts of nitrate may be employed. According to examples (1) a spodumene ore was heated to 1130 DEG C. to convert it to b spodumene.  The product was ground and mixed with sodium nitrate and sodium carbonate and heated for 1 1/4 hours at 675 DEG C.  The roasted material was extracted with an aqueous solution of sulphuric acid at 95 DEG C. and the resulting slurry was filtered and the residue repulped with water.  The combined leach liquor and washings at a pH of 6 were treated with calcium hydroxide to a pH of 12 after which sodium carbonate was added to precipitate calcium carbonate. The filtrate was adjusted to pH 8 by sulphuric acid and after reduction in volume by boiling was treated with sodium carbonate to precipitate lithium carbonate.  The filtrates and washings may be recycled. (2) b  spodumene was mixed with sodium nitrate and sodium carbonate and heated at 675 DEG C. and equal portions of the roasted product were extracted with hot and cold water with and without added sulphuric acid.  The percentage extractions are compared. Further examples describe the treatment of spodumene with sodium nitrate and sodium carbonate, sodium nitrate and sodium sulphate, sodium nitrate and sodium hydroxide, sodium hydroxide and sodium carbonate, sodium hydroxide and calcium sulphate, and sodium hydroxide with calcium oxide.

Title: Improvements in or relating to reinforced structures made from synthetic resins
Filed: 1937-06-11
Abstract: 497,225. Reinforced synthetic resin structures. BAKELITE, Ltd. (Bakelite Corporation) June 11, 1937, No. 16298. [Class 114] [Also in Group V] A synthetic resin structure and particularly an airscrew blade is reinforced with metal wire having a small diameter of the order of À003 to À008 of an inch and the wires are arranged that there is no substantial contact between them and no two wires cross one another in contact. The synthetic material is preferably phenol formaldehyde resin but other thermostatic or thermoplastic materials such as urea, acrylic, venyl, casein or cellulose materials may be used. The materials may have also fillers added and dyeing materials and also plasticizers. The wires are made into a fabric of which the metal wires 1 form the warp and a textile fibre 2 the weft, preferably one or other of these elements is given a crinkled or wave formation. Such a fabric is embedded in the synthetic material or coated on both sides with a layer of this material and then built up with multiple layers to form the desired structure, heat and pressure being applied as necessary. For making an airscrew blade, layers 14 are placed within a two-part mould 5, 6 which connects with a pressure chamber 9. Within the hollow is a distensible bag member which may be filled with liquid or plastic material 13 by depressing the plunger 11 until the desired pressure is attained. Simultaneously heat is applied through the conduits 15 in the mould. When the article is to be solid, the bag 12 is made of a ductile material and is provided with holes or slits and the material 13 which is extruded is constituted by the moulding material. In an alternative method the wire, preferably in the form of impregnated braid, is wound around a core and then coated with the synthetic resin or like material and then subjected to heat and pressure. The core may be of some material, for example, wood or a synthetic resin which it is desired should remain as a permanent core but may be formed of an easily fusible metal which may be melted out if a hollow structure is desired.

Title: Improvements relating to bolt and rivet guns and the like
IPC: B25C1/12
Filed: 1952-06-30
Abstract: 706,463. Gun for firing bolts and the like. BOSSONG-WERK GES. June 30, 1952 [Nov: 21, 1951], No. 16441/52. Class 119 A gun for firing bolts, rivets, and the like into a solid mass is in two parts 1, 31, one containing the bolt 23 or the like and the cartridge 17 and the other part containing the firing pin 41 and its releasing mechanism, the first part having a cylindrical extension, such as a bolt 25, which fits into a bore of the second part and being secured in place by a releasable locking device. Further a guide 32 is provided, for connecting the two parts in such manner as to permit them to be separated from one another to a limited extent. In the construction shown, the bolt 25 is secured by a pin 26 to a downwardly projecting eye 24 of the part 1, which part has a sleeve 2 in which the barrel 3 can move against the action of a spring 5. The barrel has at one end a sound-absorbing device 9 and at the other end a cartridge holder 16. The bolt 23 is held in place by two or more spring-urged clamping members 19. The cylindrical extension 25 extends into the bore 30 of the part 31 to which the handle 39 is screwed, and is releasably held in place by a hook 48 which is formed on a locking ring 47 and which engages in a groove 28 formed near the rear end of the extension. In order to release the two parts 1, 31, the hook 48 is moved clear of the groove 28 and the parts are then moved apart. During such movement a cross pin 27 on extension 25 is guided in a guide slot 32 in the part 31, the slot terminating in a circumferential part 33 which limits the extent of separation. Once the separation has been effected, the part 1 can be swung about the bolt 25 and re-loading can be effected. During the separating movement a spring- pressed pawl 67, Fig. 3, on the part 31, by engaging in a recess 60 in a plate 58, guided for sliding movement on the barrel, causes the plate to move relatively to the barrel and thus by its part 61 to eject the spent cartridge case. A rib 63 on the barrel assists in guiding the plate and also serves, by its front sloping face 65, to lift the pawl clear of the recess 60 after ejection. The firing pin can be retracted by a handle 45 against the action of a spring 43, and is released for firing by a trigger 56 associated with sear 50. In use, the barrel is pressed against the object into which the bolt is to be fired, such action serving to compress the spring 5 and to move the cartridge holder 16 rearwardly until it abuts against a guide 36 for the firing pin. When firing into soft materials the bolt may pass through a ring placed in a recess 8, the ring being held in position by magnetizing the barrel.
