Abstract: 1,164,242. Selective punching devices. FACIT AB. 3 May, 1967 [3 May, 1966], No. 20580/67. Heading B4B. A device for punching holes in cards, tapes and similar recording media comprising a punch die, a plurality of punches and guide means for the punches is characterized in that the guide means, the punches and the punch die are combined in an interchangeable punch head which is provided with a cylindrical shank portion capable of angular and longitudinal adjustment in a base member. In the form shown, the shank portion 12 of a punch head 14 is adjustable in a cylindrical bore 11 of a base-plate 10 being held in position by a setscrew 13. The punch head at its other end is of segmental cross-section having a flat face 16. Mounted in a bore 18 of the shank portion 12 is a punch die 17 previously drilled with punch holes (19), Fig. 3 (not shown), which have clearance downwards so that punched-out matter will clear itself. The punch die can be used as a jig for drilling the guide holes 20 in the punch head. Punches 21 are mounted in the holes 20 and the shank portion 12 inserted in the bore 11 of the plate 10. A reduced portion 23 at the upper end of each punch engages a slot 24 provided in an associated bell crank 27. The bell cranks have a common pivot 28 and are actuated by push rods 29 engaging recesses 29a in the bell cranks. The push rods are actuated individually, e.g. by electromagnets. To prevent deformation of the overhanging die during punching, support pads 30, 31 are provided, these pads having oblique sides 32 defining a shoot for the punched-out matter. The recording tape is inserted laterally into the space 35 between the punch head and die. The punch head is formed of a self-lubricating bronze or other self-lubricating material. Alternatively, the punch head may be formed with an axial bore 15 for lubricant. In a modification, the punch head (35), Figs. 4 and 5 (both not shown), is a cylinder having an offset bore (36) and an axial slit (38) which partly intersects the bore for guiding the recording tape through the punch head. The portion (40) of the cylinder below the slot provides the punch die and has holes (19) machined therein. A hollow bush (37) is forced into the bore (36) and holes are drilled through the walls of the bush using the die as a drill jig. The punches are mounted in the bush holes. The bush has a channel for lubricant. This punch head is mounted by inserting the cylindrical shank portion (41) in the bore 11 of the base-plate 10.

Title: A process of producing highly refractory masses
IPC: C04B35/44
Filed: 1928-07-17
Abstract: 324,312. Sprenger, A. July 17, 1928. Refractory substances.-A highly refractory substance is produced by fusing together the oxides of chromium, aluminium, silicon and magnesium, or minerals containing such oxides, in such proportions that the alumina may combine with silica or with silica and magnesia, and. the chromium oxide may combine with magnesia. to form simple double oxides. Preferably the last double oxide predominates in the product and uncombined chromium oxide or magnesia may be present. The melting of the mixture is performed in an electric furnace, and the heating and cooling are so conducted that the product contains 50 per cent or more of vitreous con. stituents. The melt mav be tempered during or after cooling. The slag derived from the process of producing ferro-chromium may be employed as a raw material, with additional chromium ore if necessary. The refractory substance may be cast or may be crushed and moulded with binding agents. Specification 302,087 is referred to.

Title: Improvements in or relating to the preparation of esters
IPC: C07C51/255
Filed: 1963-05-24
Abstract: Dimethyl o-methylterephthalate is made by a reaction sequence in which (1) 1,3-dimethyl-4-methoxymethyl-benzen is oxidized by treatment in the liquid phase with oxygen or a gas-containing oxygen at 90-200 DEG  C., (2) the resulting 2,4-dimethylbenzoic acid is esterified with methanol, (3) the methyl 2,4-dimethylbenzoate is further oxidized to yield a mixture of methyl o-methylterephthalate and methyl 4-methylorthophthalate, (4) the mixture is esterified with methanol, and (5) dimethyl o-methylterephthalate is crystallized from a solution of the ester mixture in methanol.  The mother liquor from the final crystallization, consisting mainly of dimethyl 4-methylorthophthalate, may be converted into trimethyl trimellitate by further oxidation followed by esterification with methanol.  In modifications of the process, a mixture of 1,3-dimethyl-4-methoxymethylbenzene and methyl 2,4-dimethylbenzoate, or a mixture of 1,3 - dimethyl - 4 - methoxymethyl-benzene, methyl 2,4-dimethylbenzoate and dimethyl 4-methylorthophthalate, is oxidized as described above and the product, after esterification with methanol, is fractionated to yield fractions containing the desired products and other fractions suitable for return to the process. The oxidations may be effected under raised pressure, e.g. 1-10 atm., and in the presence or absence of a catalyst, e.g. cobalt salts of fatty acids.  Examples are given.  The 1,3-dimethyl-4-methoxymethylbenzene used as a starting material may be prepared by chloromethylating m-xylene with formaldehyde and hydrochloric acid and treating the chloromethyl xylene so obtained with methanol and alkali.

Abstract: 738,757. Casting processes. BRISTOL AEROPLANE CO., Ltd. July 21, 1953 [Aug. 20, 1952], No. 20952/52. Class 83 (1). In a method of casting metals in a porous mould, such as a sand or wax - investment mould, an inert gas is caused to pass through the pores of the mould and into the mould space to expel air entrapped in the pores and also in the mould space, and the casting metal is poured into the mould while it is impregnated and filled with the inert gas. An investment mould 10, Fig. 1, for turbine blades, is covered by a member 16 clamped against an asbestos mat 21 supported over a furnace, the mould space communicating with the atmosphere through the pouring gate 13, 14. Inert gas, e.g. argon, is supplied under pressure through a pipe 19 and after a period of time sufficient to ensure the expulsion of the air from the pores of the mould and the mould space, the metal is poured by inverting the mould and furnace assembly, the flow of inert gas being maintained meanwhile and after casting while the metal is allowed to cool sufficiently to solidify. After solidification the mould on a base 23, Fig. 2, is covered by a vessel 26 with a valve 30, and propane under pressure supplied to the chamber 27. The gas jet is lit before the vessel 26 is placed in position, to prevent an explosion. Ducts 31, which may be formed by passing a wire through the mould, ensure that argon penetrates to the mould space remote from the pouring gate. Nitrogen may be used instead of argon.

Title: Improvements relating to the recovery of waste gases in the synthesis of urea from ammonia and carbon dioxide
IPC: C01B32/50
Filed: 1955-07-22
Abstract: <PICT:0780683/III/1> In a process for the separation of the components of a mixture of ammonia, carbon dioxide and aqueous vapour by the selective absorption of ammonia in aqueous solutions of ammonium salts of strong acids at superatmospheric pressures, as described in the parent Specification, the absorption temperature is kept constant by circulating the absorbing solution after pressure release on its issue from the absorption column through a heat exchanger in the absorption column.  The gaseous mixture is passed from a container 2 into a column 3 where ammonia is absorbed and the solution is released through a valve 11 to a lower pressure and is then passed to a vessel 12 where part of the ammonia distils and thereby the solution is cooled.  The solution is then conveyed, wholly or partially, to a heat exchanger 4, where heat evolved by the absorption of the ammonia is removed by the solution.  As the solution is heated passing through the heat exchanger 4, ammonia is distilled from it and is separated in a vessel 13, the solution may then be wholly conveyed to a column 8 where remaining ammonia is removed by steam heating, or partially recycled to the exchanger 4. Specification 740,638 also is referred to.
