Patent GB-341031-A (GB)
Title: Improvements in or relating to the manufacture of aliphatic acids
IPC: C07C51/235
Filed: 1929-09-06
Abstract: Acids such as acetic acid, as such or in the form of esters, are produced by passing a mixture of an alcohol and air or oxygen with steam and/or the corresponding acid if desired, over a catalyst comprising a metallic oxide, hydroxide, or carbonate other than an alkali or alkaline-earth oxide, hydroxide, or carbonate, alone or with the addition of an oxide, hydroxide, or carbonate of an alkali or alkaline-earth metal, but when a mixture is employed it is such that metallates are not formed.  The temperatures employed are too low for the production of ketones. Preferably the catalyst consists of one or more of the oxides of metals whose acetates yield acetic acid on heating, with or without steam, such as manganese, cobalt, nickel, iron, zinc, lead, and uranium; and the catalysts may also contain an admixture of an alkali or alkaline-earth metal oxide, hydroxide, or carbonate.  Copper and aluminium oxides are also suitable.  The reaction may be effected at 150-400 DEG  C. or, when the catalyst contains an alkali or alkaline-earth metal compound, at 150-300 DEG  C., and the pressure may be normal, reduced, or increased, such as 3-10 atmospheres or more.  The reaction mixture may contain one or more volumes of oxygen to one of alcohol vapour, for instance from 2 to 10 volumes of oxygen to one of alcohol. Preferably steam is added before the reaction is effected, and this may be in relatively large quantity such as 2-10 times the volume of the alcohol vapour.  The gas mixture may be passed through a tube of copper, iron, silica, earthenware or "staybrite" containing the catalyst.  In an example, a mixture of ethyl alcohol, oxygen and steam in the volume proportions 1 : 3 : 5 is passed through a tube e.g. of copper containing for instance ferric oxide, at 280-320 DEG C. or, if a catalyst such as a mixture of 2 molecules ferric oxide to one of calcium carbonate is employed, the temperature should be 230-280 DEG  C.

Title: Acid-resistant containers made from synthetic-resin mouldable compositions
IPC: H01M50/145
Filed: 1945-10-17
Abstract: Acid resistant containers, such as battery boxes, are made from a mouldable composition comprising hydrolysed vegetable fibrous material free from acid-soluble material and containing 65-57 per cent cellulose and 35-43 per cent lignin impregnated with a single-stage thermosetting phenol-formaldehyde resin or cresol-formaldehyde resin, or a combination of both, in quantities of 15-45 per cent of the total composition.  The vegetable fibrous material, i.e. hardwood sawdust, such as red oak, maple, or gum sawdust, is bleached with dilute sulphuric acid, either in a steam-heated chamber or in a steam-jacketed tube until pure ligno-cellulose remains.  The hydrolysed product is filtered off, washed and ground either wet or dry, the material being dried in either case to a moisture content of 4-15 per cent, and an aqueous solution of the synthetic resin added, the water-wood fibre ratio being 0.5 : 1-2.5 : 1.  An accelerator, such as hexamethylenetetramine, ammonium hydroxide or calcium oxide, and a mould lubricant, such as 2-50 per cent fatty acids or their salts, may be added and the mix passed through a rubber mill to complete the impregnation of the fibres.  The sheeted material is granulated and dried to a moisture content of 4-5 per cent by weight.

Title: Improvements in means for automatically closing and opening railway crossing-gates or barriers by the running train
IPC: B61L29/20
Filed: 1927-10-21
Abstract: 296,917. Breins, H. Oct. 21, 1927. No Patent granted (Sealing fee not paid). Operating barriers by treadles and the like, and by chain and cord arrangements. -Railway crossing barriers are operated by the depression of a series of depressible rails 4, 5, 6 which are moved by the train to operate levers 14, 16 and pulleys 17 controlling cables 19, 20, 21 provided for opening and closing the barrier 2, the rails when loaded moving the pulleys so that the cables are free to act through counterweights or springs, the release of the rails causing the pulleys to engage the cables again so that the cables are tensioned. When the train moves in the direction of the arrow 76, Fig. 1, depression of the rail 5 causes the barrier 2 to be lowered into the closed position, the barrier being lifted to open the crossing after the train has left the depressible rail 4, the rail 6 being operative to reset the mechanism. Depression of the rail 5 oscillates the levers 16 through links 14. This lifts the pulleys 17 and slackens the cable 19. A weight 27, Figs. 1, 4 and 8, attached to one end of the cable, causes a partial rotation of a pulley 25 to move a cam 28 which then displaces a pawl lever 56 into the the position shown in Fig. 8. The wheel 49 is thereby released and is then rotated by a weight 50 to oscillate a lever 60 connected through a rope 61 with a bell 63 and, towards the end of its movement, to move a wedge bolt 45 so that the levers 37 release a bar 39. The barrier 2 is then free to close by gravity and as it falls it pulls on the cable 20 and raises a weight 35 and lowers the bar 39. The wheel 49 is rotated backwardly to reset the pawl 56 and reset the levers 37. The train has by this time left the rail 5, which is then raised by its spring to tension the cable 19 by the pulleys 17 and retore the counterweight 27. The subsequent depression of the rail 4 by the train causes the pulleys 17 to be raised, the slack of the cable 20 being taken up by the counterweight 35, which descends and is held by the locking mechanism 37. As the train leaves the rail 4 the pulleys are lifted and cable 20 is tensioned, causing the barrier 2 to be raised to open the crossing The depression of the rail 6 effects a repetition of the operations caused by the depression of the rail 5, the cam 28 being restored to its initial position and the parts being reset for the operattion of the barrier by a train approaching in either direction.

Abstract: 670,313. Feeding bottles; producing filled containers. MEYER, F. Oct. 18, 1948 [Oct. 21, 1947 ; Dec. 24, 1947 ; July 27, 1948], Nos. 28096/47, 34164/47 and 20018/48. Classes 94(i) and 125(i) [Also in Groups V and VI] Containers such as ampoules of synthetic thermoplastic material are made and filled with a fluid by closing a tube of the material at its lower end, slitting the tube longitudinally, feeding the fluid into the' tube through the slit, resealing the slit, and then sealing the tube transversely at spaced positions, each sealing operation being made below the level of the fluid, to exclude air from the containers so made. The tube may be formed by extrusion or by building it up from one or more tapes and may be rectangular or triangular in section. The tube may be flattened and wound on to a spool for storage before use. The tube 19 is fed downwardly and cut longitudinally by rollers 21 to allow fluid to be filled into the tube through a feed pipe 7. The cut is then sealed by rollers 23 and the tube sealed transversely to form the containers by rollers 13. The containers may be sealed longitudinally by rollers 17 to form several containers side by side. Several tubes may travel adjacent to one another and different fluids may be passed into each tube. A buffer material such as fabric, paper or "Cellophane" (Registered Trade Mark) may be introduced between the synthetic thermoplastic material and any hot metal surfaces, to prevent the thermoplastic material from sticking to the rollers. The buffer material may be allowed to adhere to the material. Deformation of the walls of the tube may be controlled by an outer mould. Parts of the tubes may be of different thicknesses to produce a greater bulge on one side of the container. The pressure of the fluid may be kept constant automatically. Specifications 553,563, [Group V], 570,451, 591,442 and 642,530 are referred to. According to the first Provisional Specification the the tube may be filled through its upper end as the tube is formed. The containers may be shaped to form a neck at one end and a recess in the other end, like a wine bottle. The entire production may take place in an atmosphere free from oxygen. An indication of the contents of the containers may be printed on them during production. Reinforcing ribs may be provided on the containers. The containers may be filled with milk and formed with a teat end for use as a feeding bottle.
