Patent GB-806803-A (GB)
Title: Improvements in and relating to the continuous casting of metal
Inventor: HESSENBERG WILFRID CECIL FREDE
IPC: B22D11/053
Filed: 1954-05-25
Abstract: 806,803. Continuous casting - machines. BRITISH IRON & STEEL RESEARCH ASSOCIATION. May 20, 1955 [May 25, 1954, (2)], Nos. 15382/54 and 15384/54. Class 83 (1). In continuous-casting, the mould is moved in the direction of billet-withdrawal at a speed greater than the withdrawal-speed, to release the billet from the mould, and then returned in the opposite direction. The mould 12, Fig. 1, is supported on three springs 17, and aligned with the springs are pneumatic-rams 21 of the type which provide a sudden impact on the application of compressed-air to the inletpipes 22. In operation, if the billet sticks to the mould-wall, the mould moves downwards against the action of the springs 17. When the tension reaches a predetermined value, compression of the springs allows the mould-topplate to engage a switch to supply pressure-air to the rams 21 so that they apply an impulse to the mould to cause it to move downwardly for a short distance at a speed greater than the withdrawal-speed of the billet. This impulse releases the billet from the mould. The return of the mould to its normal rest-position may be damped by shock-absorbers. Means other than the springs 17, and acting without substantial movement of the mould, may be used to control the application of the compressive release-impulse. In a modification, Fig. 2, the compressive-force on the billet is applied cyclically by cams 32 to prevent sticking, instead of only when sticking occurs. The cams are such that over the larger part of the cycle the mould moves downwardly at a speed greater than the withdrawal speed, and for the remainder of the cycle the moulds return quickly under the action of springs 31. The first Provisional Specification refers to the use of an electromagnet to apply a repulsive or attractive force to the mould. Specifications 715,782, [Group XXXII], and 794,255 are referred to.

Patent GB-731638-A (GB)
Title: Improvements in or relating to the production of alumina-chromia-molybdena catalystsfor reforming
IPC: B01J23/28
Filed: 1953-06-04
Abstract: A catalytic composite of alumina, chromia, and molybdena containing less than about 20 per cent by weight of molybdena is prepared by impregnating a co-gel of alumina and chromia with an aqueous solution of a molybdenum compound and drying the product. An alumina-chromia hydrosal having a solids content of at least 10 per cent by weight is obtained by mixing aqueous solutions of sodium aluminate and chromic acetate, the sodium to aluminium atomic ratio and the acetate to chromium ion ratio being such as to effect rapid gelation of the hydrosol; the sol may be introduced into a water-immiscible medium, for example as described in Specification 576,058 in order to form gel spheroids; alternatively the gel may be prepared as irregular particles or as extruded or pressed pellets.  The gel is aged by contact with a solution of an ammonium salt of a mineral acid, or a mineral acid itself, at pH 8-9.5 for 2-24 hours, and then washed free from anions.  After drying with superheated steam or heated air, the gel is calcined at 500-1200 DEG  F. in an inert or reducing atmosphere, e.g. flue gas or hydrogen, and is then impregnated with a solution of, for example, molybdic acid or alkali metal or ammonium molybdate.  Impregnation may be carried out by evacuating the gel and adding the solution, by a continuous countercurrent contacting process, or by first purging the gel with steam.  An alternative method is to impregnate the hydrogel before drying and then dry in superheated steam.  After impregnation the composite is heated slowly to a temperature not exceeding 1000 DEG  F. in an atmosphere free from oxygen, e.g. in a blanket of steam produced during the heating. The finished catalyst preferably contains 10-30 per cent (especially 20-30 per cent) chromia, 50-89 per cent (especially 58-72 per cent) alumina, and 1-20 per cent (especially 8-12 per cent) molybdena, and shows improved selectivity, activity, and stability in hydroforming petroleum naphtha fractions to give products of high octane number. Sodium aluminate for use in the manufacture of the catalyst may be prepared with varying sodium to aluminium atomic ratios by heating caustic soda and aluminium trihydrate either in an open kettle or an autoclave.  Sodium aluminate solutions of low sodium to aluminium ratio may be stabilized by the addition of glycerine, starch, or sugar.

Title: Improvements relating to the manufacture of substituted alkyl chlorides
Filed: 1932-06-04
Abstract: Aminoalkyl chlorides of the formula R.(CH2)n. Cl, in which R represents a dialkylamino or piperidyl residue and n is 7, 8, 9, 10 or 11, are prepared by treating the corresponding aminoalcohol with thionyl chloride at a low temperature, preferably below 0 DEG  C. in a solvent such as chloroform.  Examples are given of the preparation of lambda-diethylamino-n-undecyl chloride, c  - diethylamino - n - heptyl chloride, k - dibutylamino - n - decyl chloride, k - N - piperidyl - n - decyl chloride and lambda - dibutylamino-n-undecyl chloride from the corresponding amino-alcohols.  Reference is also made to the following products:--#q - diethylamino - n - octyl chloride, i-diethylamino-n-nonyl chloride, k-diethylamino-n-decyl chloride, k-dimethylamino-n-decyl chloride, k-diamylamino-n-decyl chloride and lambda - diheptylamino - n - undecyl chloride. Specification 359,180 is referred to.  The aminoalcohols employed as starting materials are obtained by (i) interaction of the appropriate secondary amine and chloroalcohol, or (2) reduction with sodium and alcohol of the corresponding aminocarboxylic acid alkyl esters, which latter may be prepared by treating the halogen-substituted carboxylic acid alkyl esters with the requisite secondary amine.  Thus, c -diethylamino-n-heptyl alcohol results from the interaction of c -chlor-n-heptyl alcohol with diethylamine, whilst lambda-diethylamino-n-undecyl alcohol is obtained by treating ethyl k-brom-n-undecoate with diethylamine and reducing the ethyl k-diethylamino-n-undecoate formed.  The following aminoalcohols are also referred to:--#q - diethylamino - n - octyl, i - diethylamino - n - nonyl, k - diethylamino - n - decyl, k - dimethylamino-n-decyl, k-dibutylamino-n-decyl, k-N-piperidyl - n - decyl, k - diamylamino - n - decyl, lambda - dibutylamino - n - undecyl and lambda - diheptylamino-n-undecyl alcohols.

[Classes 100 (i) and 100 (ii).] Platen machines; feeding webs.-In a machine for printing strips of tags which are partially severed, the strips 90, Fig. 8, are fed through the machine by means of reciprocating pivoted fingers 37a, 37b engaging the edges of the leading tag and the succeeding tag respectively, and the strip 90 passes over a table 82 formed with recesses 82b, 82c to permit the fingers to press 'down the forward edge of a trailing tag below the rear edge of the leading tag to ensure engagement of the fingers. If three gummed tags are operated on the strip passes from a roll 85 under plates 83, 84 through a slit 89 and then over the table 82. The fingers 37a, 37b are attached to a member 49 pivoted to a reciprocating crosshead 51 guided in slots 52 in a member 53 carried by a box-like frame 20 which supports the operating parts. The crosshead is reciprocated by an oscillating lever 57 having a slot which engages a pin 55 on the member 49. The lever 57 causes the fingers to be pressed downwards on their forward motion and to be raised on their return movement, the pivotal extent of this movement being limited by stops. The lever 55 is fitted with an adjustable pivot which is - set to cause exact register of the partial slits in the strip 90 with the cutters 39, 38. If thick tags with attaching staples are used, the strip 90 is fed over the plates 83, 84. The strip is guided laterally by a spring-pressed plate 47 formed at its lower edge with a dovetail groove 48a for engaging the edge of the strip. The 'tags are printed by a type member 27 attached to a lever 28 on an oscillating shaft 29. An inking-pad 30 is connected by a link 34 to the lever 28. The shaft 29 is operated by a crank 77 on the main shaft 22, and an arm 72, Fig. 3, on the shaft 29 is connected by a sleeve 74 and a spring 80 to an adjustable connecting- rod 75 operated by the crank.
