Abstract: 808,839. Ingot moulds. DOITTAU PRODUITS METALLURGIE. May 11, 1955 [Oct. 11, 1954], No. 13622/55. Class 83 (1). A prefabricated hot-top lining element consists of a layer of insulating material 7 bonded to a layer of exothermic material 8. Four such prefabricated slabs are cemented to ribs 4, 5 on the hot-top frame 1, there being a secondary insulating layer of air 13. The insulating material is preferably porous, and gas-collection channels 14, Fig. 4, may be formed therein or in the exothermic material. In the latter case channels 19, Fig. 4, lead the gases 20 into the centre of the hot top for full combustion, and the exothermic material is limited to a band extending between the upper and lower limits of the molten and solidified ingot. The insulating layer may be of sand, silica, chamotte or kieselguhr, and may be perforated.

Patent GB-728913-A (GB)
Title: Improvements in or relating to preparation of glycols and alcohols by the "oxo" synthesis
IPC: C07C29/16
Filed: 1952-06-04
Abstract: Glycols and/or alcohols are made by reacting non-conjugated cyclic diolefine compounds dissolved in a non-polar solvent with CO and H2 in the presence of a carbonylation catalyst at elevated temperatures and pressures, the ratio of the solvent to the cyclic compound being between 1/2 and 5/1 , preferably 2/1 to 5/1 by volume, with subsequent hydrogenation of the aldehyde product after removal of catalyst. In an illustration of typical apparatus 1-vinyl-cyclohexene-3 is treated with H2 and CO in the presence of a carbonylation catalyst such as cobalt naphthenate or stearate and a non-polar solvent such as heptane or hexane at preferred temperatures and pressures of 225-375 DEG  F. and 2000-4000 p.s.i.g. respectively, the residence time being adjusted according to the desired product, long times, e.g. 1/2 -10 hours, tending to the eventual production of glycols.  The products from the carbonylation zone after gas separation and optional return of monooxygenated compounds, after phase separation and return of the hydrocarbon layer in which mono-aldehyded but not di-aldehydes are soluble, are treated for catalyst removal and hydrogenated preferably in the presence of a molybdenum sulphide on active carbon catalyst, cf.  Specification 664,974, preferably at 400-500 DEG  F., and 2000-3500 p.s.i.g., and the products fractionated to yield a C9 monoalcohol and C10 glycol. Examples are provided in which 1-vinyl-cyclohexene-3 and dicyclopentadiene are subjected to the Oxo-synthesis in the presence of a cobalt catalyst and the effect of solvents, residence times and solvent diolefinic ratios on the nature of the products shown.  It is stated that the diolefines used may contain other groups containing oxygen, halogen, sulphur or nitrogen.  Specifications 614,010 and 647,363 also are referred to.

Title: Improvements in or relating to hydraulic jacks
Inventor: CONWAY HUGH GRAHAM
IPC: F15B15/26
Filed: 1953-05-19
Abstract: 749,262. Hydraulic jacks. BRITISH MESSIER, Ltd. May 18, 1954 [May 19, 1953], No. 14095/53. Class 69 (2). A hydraulic jack is locked in its extended position by a crown of spring claws 26 which are attached to the jack cylinder 11 and are engageable in a recess in a locking collar 34 connected to a piston 19 and jack rod 20. A locking ring 40 is slidably mounted on the rod 20 and has a lost motion connection with a secondary piston 43 located within the jack rod. A spring 47 urges the locking ring to the right. Liquid is admitted at an inlet 24 to extend the jack and is also applied to the rear of piston 43 to move it to the right till it abuts a partition 41 in the jack rod. Towards the end of its stroke the claws 26 contact a chamfered edge of the lock collar and are contracted and slide within the collar, forcing the locking ring 40 back against the pressure of spring 47, until the heads of the claws engage in the recess. The locking-ring is then moved forwardly by the spring 47 so that it comes within the crown of claws and locks them in position. To unlock the jack, pressure is applied to an inlet 25, the liquid acting on the forward end of the piston 43 to force it back against a stop 50 and move the ring 40 clear of the crown of claws. In a modification an additional spring bears on the back of piston 43 and helps to maintain the parts locked when pressure is not applied at the inlet 24. Fig. 3 shows a differential-type jack in which pressure is permanently applied at inlet 25. The spring 47 bears at one end against a sleeve 52 secured to the jack rod 20, and the piston 43 works inside the sleeve. The piston 43 has an extension 53 extending into a portion 54 of the rod 20 and has a greater area exposed to pressure on its left hand side than on its right. When pressure is released at 24, the pressure permanently applied at 25, acting on a shoulder 55 between the extension 53 and piston 43, forces the locking-ring back against the pressure of the spring 47. Specification 527,225 is referred to.

Abstract: 337,776. Siemens & Halske Akt.-Ges. March 2, 1929, [Convention date]. Relay devices.-In apparatus in which a member follows the movement of the pointer of a measuring instrument periodically, an optical indicating device is moved by the member to give a visible indication of the position of the instrument pointer. As shown in Figs. 1 and 2, the measuring instrument pointer 41 moves over a fixed support 42 and is periodically pressed into engagement therewith by a bracket 43. The arms 44, 45 which move to engage the hand are mounted on spindles 46, 47 and each is operated by mechanism, as shown for the spindle 46, comprising a pinion 48, toothed quadrant 49, spring- controlled lever 50 and operating cam 53. On the spindle 47 is freely mounted a sleeve 55 carrying the adjustable member 57 and gear wheel 56. The wheel 56 meshes with a pinion 58 which, by means of a belt drive 59, actuates the indicating band 61 The band, which passes behind a window, is illuminated from the rear and is balanced by a counterweight 62. The member 57 has pivoted thereto, at 64, a member 63 having a pin 65 engaging a triangular recess in an arm 66, guided in a sleeve 77 and provided with a brake block 67 normally bearing on a fixed segment 68.

Title: Improvements in or relating to the oxidation of unsaturated aldehydes
IPC: C07C47/19
Filed: 1940-09-26
Abstract: Unsaturated a -b -aldehydes are oxidized with molecular oxygen, preferably in the presence of a catalyst such as osmic acid, chromic acid, vanadic acid or molybdic oxide in a non-alkaline medium and at a temperature below the resinification temperature p  of the hydroxy-aldehyde.  The temperature should not exceed 50 DEG  C. and preferably water is present in the reaction mixture and may be added in portions.  A saturated aldehyde such as acetaldehyde may be present and increases the yield of dihydroxy aldehyde.  The unchanged unsaturated aldehyde and the unsaturated acid produced therefrom may be removed by low temperature distillation or the unsaturated acid may be extracted with a solvent; or the reaction mixture may be treated to cause the hydroxy aldehyde to react with another reagent. For instance, an alcohol may be used to produce a hydroxy-acetal and esterify the unsaturated acid; or hydrogenation may be effected to produce a trihydric alcohol and a saturated acid; or the reaction mixture may be heated with dilute sulphuric acid to convert the hydroxy-aldehyde to a keto-aldehyde. In examples, crotonaldehyde is oxidized to methyl glyceraldehyde and crotonic acid and acrolein to glyceraldehyde and acrylic acid. Specification 560,166 is referred to.
