Title: Improvements in the conversion of hydrocarbons of high boiling point into valuable products, especially those of low boiling point
IPC: C10G69/04
Filed: 1928-07-27
Abstract: 296,700. I. G. Farbenindustrie Akt.- Ges. Sept. 5, 1927, [Convention date]. Hydrogenation, destructive. - Low boiling- point oils are obtained from coals, tars, oils, &c. by subjecting the initial materials to a continuous cracking process with or without hydrogen under such conditions that carbonaceous deposits are formed with a minimum production of gas and then in a second stage destructively hydrogenating the resulting products together with the carbonaceous deposits. Preheated crude oil at sp. gr. 0.94 is passed at high velocity through a set of tubes heated at 450-500‹ C. under a pressure of 30-50 atmospheres. The oil and carbonaceous deposits are passed to a chamber where the pressure is released to separate the products of low boiling-point. The residue is transferred by a pump to a high-pressure chamber and treated with hydrogen under a pressureof 200 atmospheres and at 480‹ C. in presence of a catalyst containing molybdenum and chromium. Benzines of a saturated character are obtained. Suitable catalysts for the process are those specified in Specifications 247,585, 247,586, 247,587, 257,256, 258,272. 272,832, 272,833, 275,663, 275,664, 275,670, 276,001, and 307,946.

Title: Improvements in stabilizing devices for vehicles
IPC: B60G17/015
Filed: 1958-07-08
Abstract: 899,003. Road vehicle undercarriages. LINDBLOM, K. J. July 8, 1958 [July 17. 1957; March 20, 1958], No. 21919/58. Class 108(2). The tendency of a motor vehicle to roll during cornering, is counteracted by a control mechanism which extends the suspension units on the depressed side of the vehicle, and which is operated by a movable weight which rests on supporting means secured to the vehicle body, and which weight is movable along the supporting means under the influence of centrifugal and gravitational forces,. Hydraulic suspension units 29, 30 (Fig. 1), extending between axle 3 and body 1, are fed with fluid in accordance with the position of a rotary valve 21 which is controlled by sliding movement of a weight 8 urged to a neutral position in an oil filled cylinder 7 by a spring 9. The weight is also movable by hydraulic pressure generated by a loose piston 16 when the steering mechanism 15 is subjected to violent movement. In a modification (Fig. 3) a slide valve 46 directs fluid from a pump 47 to and from pipes 62, 63 in accordance with rolling movement of a weight 33 on a flexible leaf spring 36. The pipes 62, 63 are connected to either hydraulic suspension units, or hydro-pneumatic suspension units (Fig. 8a) provided with additional manually controlled vehicle height control cylinders 139, 147. These hydro-pneumatic suspension units are connected between the vehicle body and trailing arms 130 (Fig. 9, not shown). In a modification (Fig. 6, not shown) the weight 33 rolls on a rigid concave surface In the embodiment shown in Fig. 5, movement of a sliding weight 91 causes the level of mercury in tubes 96, 97 to rise, thereby completing an electrical circuit to one of a pair of magnetic clutches 102, 103, and so causing a motor 104 and differential 109 to drive a hydraulic or mechanical adjusting mechanism 111 in the required direction to correct the vehicle level.

The plates 35, Fig. 2, are spaced from the bottom of the shoot; the plates 80, Fig. 5, extend to the bottom of the shoot and retarding baffles 79 are provided between successive plates. The top edges 25 or 70 of the side walls of the shoots are steeper than the angle of repose of the coal. As shown in Fig. 2, the coal is delivered to the shoot 30 from the truck 21 through a hopper 15 with outlet shielded by a baffle 18. The shoot 30 is in the central plane of the bin ; and there are four rectangular outlets in the floor of the bin, two at each side of the shoot. Each outlet is fitted with a telescopic shoot 37, 38 and slide gates 40. The coal is guided to the outlets with minimum breakage by vertical corner-pieces 50 forming a vertical shoot with open sides into which the lumps of coal enter from the top layers. These vertical shoots may be formed as shown in plan in Figs. 3 and 4 with additional verticals 57 and partitions 58, 59. As shown in Figs. 5 and 8, two shoots 77 are provided V-shaped in crosssection. The shoots are also narrower towards the lower end.

Title: Improvements in, and relating to, liquid-level indicators, especially for fuel reservoirs
IPC: G01F23/24
Filed: 1924-09-18
Abstract: 231,083. Page, W.. I. G. Sept. 18, 1924. Indicators, electric.-Apparatus for indicating the level of liquid in a fuel reservoir comprises a tubular member 14, Figs. 2 and 3, containing mercury and communicating at its upper end with the reservoir through a nozzle 17 and at its lower end with a tube 30 having helically arranged and adjustable contacts 31. The contacts, which are held in their adjusted positions by lock-nuts 32, are connected to corresponding indicating lamps 43, Fig. 8. The tubular member 14, constituted by transverse tubes 19, 20 and longitudinal tubes 15 and 16, is supported in a casing 10 which is insulated from the fuel reservoir by a bush 39. Pressure of the fuel exerted on the mercury in the tubes 15, 16 causes the mercury to rise in the tube 30 and prepare the circuits of the lamps 43 which indicate the height of fuel in the reservoir. A switch 44 is provided on the indicator for completing the lamp circuits at any desired time. The tube 30, which is of insulating material, is supported between flanges 21, 23. The flange 23 is provided with a tube 27, which in pressure feed systems is connected with the top of the fuel reservoir, but in gravity feed systems communicates with the atmosphere through a sieve. The level of the mercury in the member 14 may be adjusted by a screw 36, which also provides for the withdrawal of surplus mercury through the holes 37, 38. The mercury is insulated from the fuel by a layer of glycerine &c., which also operates to damp any turbulent movement of the mercury. The lowest indicator lamp may be coloured red to give a " danger " signal when replenishment of the reservoir is necessary.

Patent GB-994058-A (GB)
Title: Process for treating textile materials
IPC: D06M15/05
Filed: 1961-06-19
Abstract: A waste proof finish is imparted to textile materials by treating them with a water-soluble high molecular weight finishing agent which is a natural substance containing hydroxyl, amino or imino groups, a modification product thereof or a vinyl polymer or copolymer, an alkali and a compound containing at least two groups having the formula CH2 = CH - CO - N<.  Specified finishing agents are starch, hydrolysed starch, casein, tragacanth, plant gums, hydroxy-ethyl cellulose, carboxymethyl cellulose, polyvinyl alcohol, polyvinyl esters containing hydroxyl groups, e.g. polyvinyl acetate having a content of residual acyl groups of up to 25%, polyacrylamide, polyacrylic esters and graft polymers of vinyl esters on polyalkylene glycols and their saponification and ester interchange products.  The compound containing at least two CH2 = CH - CO - N< groups may be 1 : 3 : 5-trisacroyl-s-perhydrotriazine or may have the formula (CH2 = CH - CO - NH)2-(CH2)n in which n is an integer having a value of 1-6. The alkali may be an alkali or alkaline earth metal oxide, hydroxide or carbonate, an alkali metal phosphate, ammonium hydroxide, carbonate or phosphate or a compound which liberates alkalis at an elevated temperature, e.g. an alkali metal bicarbonate or an alkali metal salt of trichloroacetic acid.  The finishing agent, the compound containing CH2 = CH - CO - N< groups and the alkali may be applied to the textile materials simultaneously by dipping, padding or spraying or the three components may be applied in any desired order in two portions or individually and successively with or without intermediate drying between successive applications.  When using as alkalis substances which yield alkalis when heated, a heat treatment may be carried out at 50 DEG - 170 DEG C. during or after application of the substances to the textile material.  The heating may be carried out in the treating bath or subsequently by dry heating or steaming, if desired under pressure.  The material may subsequently be rinsed and the alkali neutralized with acetic acid. The finishing agents may be used in admixture with plasticizers, hydrophobizing bactericidal or fungicidel agents and dyestuffs. Filaments, yarns and knitted and non-woven fabrics made from natural cellulosic fibres, e.g. cotton or regenerated cellulose, polyamide, polyacrylonitrile or polyester fibres may be treated.
