Title: Process for bonding elastomeric materials to metals
IPC: C08J5/12
Filed: 1968-07-12
Abstract: 1,223,727. Laminates. PYRENE CO. Ltd. 12 July, 1968 [26 July, 1967], No. 33412/68. Addition to 1,144,844. Heading B5N. [Also in Division C3] Elastomeric materials are bonded to metal surfaces consisting predominantly of iron, zinc or aluminium by treating the surface with an aqueous solution containing chromic acid and phosphoric acid, adjusting the water content of the coating if not at least 4% to at least 4% by weight, and placing an elastomeric material in contact with the surface bearing the moist coating and bonding the elastomeric material to the surface by the application of heat and pressure. The elastomeric materials include natural and synthetic rubbers such as sulphuric acidtreated natural rubber, neoprene rubber, styrene-butadiene rubber, butyl rubber, ethylenepropylene-diene polymers. The coating solution may also comprise fillers such as titanium dioxide, colloidal silica, attapulcus clay, aluminium metal powder and zinc metal powder. Metal salts of organic fatty acids such as zinc stearate, lead acetate and sodium acetate may also be used. The coating solution may be applied by roller-coating, spraying, flowing or immersion. The process may be used to form laminates of an elastomeric material between two metal surfaces, or to form laminates of alternating layers of elastomeric material and metal.

Title: Process for purifying gaseous formaldehyde
IPC: B01J39/00
Filed: 1961-09-21
Abstract: Monomeric gaseous formaldehyde containing water, methyl alcohol and formic acid as impurities is purified by contacting the mixture with an acidic, substantially anhydrous, non-volatile solid adsorbent for the impurities, which is inert to formaldehyde and can be regenerated by stripping with an inert gas. Suitable adsorbents are, for example, an ion-exchange resin of the cross-linked polyacrylic acid, sulphonated polystyrene or sulphonated polyphenol type; or an inert support having deposited thereon a non-volatile acid such as polylactic or polyphosphoric acid. The process may be carried out at a temperature in the range -20 DEG  to +150 DEG C., preferably from 80 DEG  to 130 DEG C.

Abstract: 1,159,852. Making reflectors. ALUMINUM PROCESSING CORP. 24 July, 1967 [8 Aug., 1966], No. 33952/67. Heading B3A. [Also in Division F4] A method of making a sheet metal article such as a bowl shaped reflector 31 comprises the steps of forming a reversely bent rim 32, inserting deformable material 37 such as a band of rubber or neoprene in the space between the rim and the body of the reflector, placing a rigid core against the inner wall 41 of the reflector, and pressing a preferably annular indentation 42 into the rim. The deformable material prevents the wall 41 from being deformed during the pressing operation. The upper edge 43 of the rim is bent towards the body of the reflector to retain the band 37. The reflector bowl may be made initially by spinning, pressing or hydroforming, and is completed by coating the wall 41 with silver or aluminium which is polished by buffing and then securing a resilient band 45 to the inner surface of the upper rim 35.

Title: Improvements in the manufacture of nitric acid from the gases obtained through the oxidation of ammonia
IPC: C01B21/26
Filed: 1921-12-16
Abstract: In the preparation of nitric acid from the gases obtained by the oxidation of ammonia, a portion of the gases are absorbed in towers in water or dilute nitric acid and the remainder are liquified by refrigeration.  After a preliminary cooling, during which no condensation occurs, the gases from the furnace are passed through coils or other acid-proof apparatus cooled by means of cold water to condense as much as possible of the water present and to give a dilute solution of nitric acid.  The uncondensed gases then enter towers fed with water or the dilute acid obtained as above described by condensation.  Before the unabsorbed gases are liquified they are dried by treatment in one or more washing towers with liquid nitrogen peroxide, in the manner described in Specification 164,734.  The acid obtained by absorption of the nitrogen oxides in dilute nitric acid is treated finally with the liquid nitrogen oxides obtained by refrigeration of the unabsorbed gases.

Abstract: 605,150. Injection moulding machines. HILL, W., and DUNN, A. Dec. 17, 1945, No. 34041. [Class 87(ii)] The ram e by which the movable mould part h' is forced against the stationary mould part b is itself the cylinder of a further ram h' by which material is forced from the injection cylinder i. The ram e carries rods g' secured to crosshead h which carries mould part h'. To close the mould pressure liquid is admitted through the port c', thus moving crosshead h along rods d to the position shown. At the same time liquid is admitted through pipes p<2> and moves the crosshead k, which carries the injection cylinder i. When the mould parts b, h', abut, crosshead k continues to move, compressing springs m and bringing the nozzle j against the mould. Pressure liquid then passes through passage e<4> and operates the injection ram h<2>. At the end of the injection stroke the pressure is released and the springs m force back the nozzle j from the mould, while the rams e and h<2> are forced back by liquid admitted through a duct f<3>. Moulding material enters the injection cylinder through the orifice i'.

Abstract: 194,795. Thomas, I. Dec. 17, 1921. Pneumatically-controlled fastenings.- Vacuum-operated means for automatically locking a railway or other carriage door 7 consists of a special piston and cylinder device 3, 1, the cylinder of which is connected to the vacuum train-pipe 2, the piston rod 5 being attached to one end of a lever 6, the other end of which is connected to a casing 10 containing a spring- pressed locking bolt 8. Further, a three-way valve 17 can be manually operated against the action of a spring to permit atmospheric pressure to raise the piston and release the bolt. The piston has two slots 26, 27 and is packed by a leather or like washer 4 which yields downwardly, when the space below the piston is open to vacuum, to permit a vacuum to form above the piston. The pressure of the outside air on the piston rod then raises the bolt 8 to locking position. When atmospheric pressure acts below the piston, the washer 4 yields upwardly and forms a tight joint.

Title: Improvements in or relating to apparatus and a process for the manufacture of sulphuric acid
IPC: C01B17/86
Filed: 1947-12-31
Abstract: In a sulphuric acid manufacturing plant, employing nitrous vitriol as catalyst, of the kind comprising one or two denitrating towers (Glovers) and one or two recovery towers (Gay Lussacs) together with several intermediate production towers connected in series, the Glover or at least one of the Glovers, besides being connected, as regards the gaseous phase, to the first production tower, is also connected in parallel with one or more of the subsequent production towers, except the last one. In Fig. 1 sulphur dioxide is fed from conduit 4 to Glovers 1a, 1b and thence through pipes 5a, 5b, 5bc to towers 2a, 2b, 2c connected by pipes 6ab, 6bc.  The gases from the last tower 2d pass into Gay Lussacs 3a, 3b and exit through funnel K, while nitrous vitriol formed in the Gay Lussacs passes to tank R11 and is pumped into the Glovers; at the same time a part of the acid from the production towers and discharged into tank R1 is pumped into Glover 1a, while the greater part of the acid is returned to the towers.  The partly denitrated acid from Glover 1a is discharged into tank R from which a part is pumped to the Gay Lussacs, while another part is passed to Glover 1b for complete denitration.  In another embodiment the towers are grouped together in a single parallelopipedal block.  The process may be controlled automatically in connection with the composition of the funnel (K) gases, which may be determined by spectroscopic analysis or from the specific heat of the gases.  Thus, a suitable device (Fig. 3) comprises a resistance r immersed in the funnel gases and a standard resistance r1, each being <PICT:0643394/III/1> <PICT:0643394/III/2> included in a separate circuit comprising a battery A, A1 and a relay D, D1.  When the operation of the plant is satisfactory, armature 23 is disposed centrally, but a change in the composition of the gases, causing an increase or decrease in the conductivity of resistance r, results in the movement of armature 23 in the one or the other direction, thereby closing the appropriate circuit to cause a corresponding movement of valve V. In a modification, resistance r1 and its circuit may be replaced by an adjustable spring acting on armature 23 in opposition to the attraction of the relay.
