Title: Apparatus for and method of stacking bricks in preparation for strapping
IPC: B65G57/24
Filed: 1975-08-27
Abstract: 1511853 Stacking bricks FORREST PASCHAL MACHINERY CO 27 Aug 1975 35307/75 Heading B8C Brick stacking apparatus comprises a plate 14 on to which a course of bricks is moved by a pusher 36, gripper 10 to lift the course off the plate and an elevator 12 which rises to receive the course from the grippers when the plate has laterally shifted. The plate 14 receives a course either in its shifted position or in its position beneath the grippers 10. To form a type course for a new stack the grippers 10 pick up the upper layer of bricks of the last course deposited on the previous stack and deposit the layer on a slotted plate 220 on a carriage 18. The tyne bricks fall through the plate on to a tray 221 and the remaining bricks are picked up by the grippers between the upper portion or outer gripping elements, and inner gripping elements (see Specification 1,511,854. The carriage 18 withdraws and the lower portions of the outer gripping elements pick up the next course from the plate 14 and deposits this course and the tyne course on to the elevator. Alternatively the inner gripping elements may be replaced by elements at the sides so that after the outer elements have picked and deposited on the elevator the final layer of the previous stack and the bottom course of the next stack, the side gripping elements remove the tyne bricks.

Title: Improvements in the production of carboxylic acids and their functional derivatives
IPC: C07C51/14
Filed: 1953-12-21
Abstract: Aliphatic carboxylic acids or their functional derivatives such as esters, anhydrides and amides are obtained by the interaction of a mono-olefinic aliphatic hydrocarbon with carbon monoxide and water, or another compound containing a replaceable hydrogen atom at elevated temperature and pressure in the presence of a cobalt salt derived from a saturated aliphatic carboxylic acid in which the cobalt atom is in complex combination with an amine compound. Other compounds containing a replaceable hydrogen atom are, for example, alcohols, mercaptans, ammonia, primary or secondary amines and carboxylic acids.  Suitable catalysts are the cobalt salts of formic, acetic, propionic or valeric acid in complex combination with preferably mono-, di- and tri-alkyl amines containing saturated alkyl radicals of between 1 and 6 carbon atoms.  Tetramethyl and tetra-ethyl derivatives may also be used. Pyrrolidine, piperidine and their N-alkyl derivatives and pyridine, and pyrrole and their derivatives may also be used.  The catalyst may be prepared by heating the constituents and if desired it may be formed in situ. Preferably the carbonylation is carried out in the liquid phase at a temperature in the range 180 DEG  to 300 DEG  C. and at a pressure above 50 atmospheres.  The olefines used as starting materials may be mixed with saturated hydrocarbons.  When the carbonylation is carried out with water fatty acids are formed, when alcohols are used instead of water esters are obtained, and when an acid is used the product is an acid anhydride.  In the examples: (a) a mixture of ethylene and carbon monoxide is passed into a mixture of water, trimethylamine and cobalt formate to give propionic acid; (b) a mixture of cobalt formate, N-butyl pyrrolidine is treated with ethylene and carbon monoxide to give propionic acid; (c) a mixture of water, cobalt formate and ethylene diamine is treated with carbon monoxide and ethylene to give propionic acid; (d) a mixture of water, cobalt formate and piperidine is treated with carbon monoxide and ethylene to give propionic acid; (e) a mixture of water, cobalt acetate and pyrrole is treated with carbon monoxide and ethylene to give propionic acid; (f) a mixture of methanol, propionic acid, cobalt formate and aqueous trimethylamine is treated with ethylene and carbon monoxide to give methyl propionate; if n-propanol is used instead of methanol propyl propionate is obtained; (g) a mixture of ethanol, ammonia, cobalt formate and pyridine is treated with ethylene and carbon monoxide to give propionamide; and (h) a mixture of alcohol, diethylamine, cobalt formate and pyridine is treated with ethylene and carbon monoxide to give N,N-diethyl propionamide.

Title: Process for the after treatment of condensation products containing sulphur
IPC: C08G75/16
Filed: 1935-12-31
Abstract: Condensation products are prepared by causing a water-soluble sulphide, hydrosulphide or hydroxide to react in an aqueous medium upon high molecular weight sulphur-containing plastics obtained by the reaction of polysulphides and aliphatic di-chloro compounds, and then subjecting the reaction mixture obtained to the action of aliphatic di-chloro compounds.  The aliphatic di-chloro compound employed for the after - treatment may be methylene chloride, symmetrical ethylene dichloride, symmetrical propylene dichloride, a .g -dichloro-b -hydroxy propane, b .b <1>-dichlorodiethyl ether, and dichloroacetals.  The sulphurcontaining plastics used as starting materials are employed preferably in the form of an aqueous suspension prepared in the presence of a substratum such as freshly precipitated barium sulphate.  In examples, an aqueous suspension of the condensation product prepared from di-(b -chloroethyl)- formaldehyde acetal and sodium tetrasulphide in the presence of barium sulphate is stirred with caustic soda and the mixture is reacted with methylene chloride, symmetrical ethylene dichloride or di-(b -chloroethyl)-formaldehyde acetal. Air is passed through the suspension and the product washed and dried.  The product may be cured by heating with a mixture of natural rubber, lamp black, zinc oxide, stearic acid, and dibenzothiazyldisulphide.  In a further example, a suspension obtained from b .b <1>-dichlorodiethyl ether and sodium tetrasulphide in the presence of barium sulphate is stirred with caustic soda and then symmetrical ethylene dichloride is added. Specifications 450,218 and 458,781 are referred to.  The Provisional Specification refers in general to subjecting the condensation products obtained from polysulphides and organic compounds having at least two replaceable negative residues first to the action of such inorganic sulphur-dissolving compounds as simultaneously have a reducing action, and then to an after-treatment with polyhalogen compounds.
