Patent GB-702950-A (GB)
Title: Improvements in or relating to oxo alcohol synthesis
IPC: C07C27/22
Filed: 1951-08-10
Abstract: Aldehydes containing dissolved cobalt obtained by the Oxo synthesis are intimately contacted in a decobalting zone with a dilute aqueous solution of an organic acid whose cobalt salt is water-soluble and oil-insoluble to form a solution of a cobalt salt which is separated. It may be recycled directly to the synthesis zone to provide catalyst and cooling, neutralized to form the hydroxide which is recycled in suspension in an organic liquid, e.g. aldehyde product or olefin, or heated with a higher organic acid to form an oil-soluble salt. Suitable acids for the decobalting are acetic, formic or oxalic.  The temperature is about 150-200 DEG F.  The Oxo synthesis is preferably effected at 200-450 DEG F. and 2500-3500 p.s.i.g. with a cobalt soap such as naphthenate or oleate or an aqueous solution of an organic cobalt salt as catalyst.  The liquid products may be in part recycled, and the remainder is mixed with sufficient acid to combine with all the cobalt and water to dissolve the salt formed.  10 per cent. of a 5 per cent. aqueous acetic acid is suitable.  A mixing time of 30-120 mins. is usual.  After stratifying, the aldehyde layer may be washed with hot, then with cold water.  The aqueous layer may be recycled to the reactor or the cobalt first converted as indicated.  The water added to the reactor should not be much above 3-5 per cent. of the olefin.  The process may be applied to aldehydes already subjected to the usual thermal decobalting. Examples employ formic or acetic acid for treating C8 aldehydes.  Specification 679,664 is referred to.

Title: Improvements in or relating to the production of foams
IPC: A62D1/02
Filed: 1938-06-25
Abstract: 517,812. Foam-stabilizing agents. PYRENE CO., Ltd. (Pyrene Manufacturing Co. ). June 25, 1938, No. 18926. [Classes 2 (iii) and 15 (ii)] [Also in Group XXI] A fire-extinguishing foam is stabilized by an amino soap which is soluble or dispersible in water. The soap may be derived from a primary, secondary or tertiary amine of the aliphatic, araliphatic or aromatic series, e.g. ethylamine, amylamine, benzylamine, aniline mono-, di- or tri-ethanolamine or ethylenediamine, alone or in admixture, and from a saturated or unsaturated carboxylic acid, e.g. caproic, caprylic, capric, lauric, myristic, oleic, linoleic or ricinoleic acid. The addition of glycerol or a glycol, e.g. diethylene glycol, or glycol ether to the soap solution or suspension enables it to be used at a lower temperature. In examples pf the preparation of foam-stabilizing agents : (1) a mixture of coconut oil fatty acids, freed from palmitic and stearic acids, is added to an aqueous solution of commercial triethanolamine to obtain an aqueous dispersion, capable of'stabilizing air foam, of an amino soap ; if the water is omitted a clear liquid capable of stabilizing air foam directly is obtained ; (2) a mixture of palm kernel oil fatty acids, freed from palmitic and stearic acids, is caused to react with ethylenediamine in water and the monobutyl ether of diethylene glycol is added ; (3) a mixture of fatty acids from (a) coconut oil (excluding the palmitic and stearic acids), (b) Myoistica venezuelensis (principally myristic acid) and (c) castor oil (principally ricinoleic acid) is caused to react with triethanolamine and a minor proportion of aniline in water.

Title: Improvements in or relating to machines suitable for trimming the heels of shoes
IPC: A43D87/00
Filed: 1954-06-29
Abstract: 776,551. Heel trimming machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., MURPHY, B. J. M., and POPE, J. R. June 28, 1955 [June 29, 1954], No. 18948/54. Class 17 (1). In a heel trimming machine having means for supporting and guiding a heel, the cutter comprises a plurality of trimming blades 16 mounted eccentrically in a cutter head and adjustable relatively thereto, stop members 22 being provided on the cutter head against which the cutting edges 24 of the blades may be moved to position them around the axis of the cutter head. The stop members are moved from operative positions to inoperative positions within the cutter head by centrifugally acting means during the rotation of the cutter. The blades are clamped between a member 8 on the cutter shaft 4 and a member 10 (not shown) on a rod 12 (not shown) passing through and keyed to the shaft, with grooves 18 on the side edges of the blades engaging eccentric ribs 20 on members 8 and 10. When the machine is at rest retractable stops 22 in member 8 protrude, as in Fig. 9, to enable the blades to be positioned, springs 36 urging ring 34 and slide 28 endwise, balls 44 in cavity 49 limiting this movement, and spring plunger 50 rocking the stops outwardly about their pivots 30. When shaft 4 rotates, and the speed well below the operating speed, balls 44 move radially outwardly and move ring 34 to the right, Fig. 6, so that cam faces 53 move the stops to the inward inoperative position. The portions of the counter guard 54 which engage the crease between the heel and upper are in the form of an involute, so that the angular position of the guard about its axis determines how closely the cutters approach this crease. Spigot 56 of the guard is journalled on slide 58, a pin 60 and groove 62 preventing axial movement and restricting angular movement. The guard is clamped in position, indicated by graduations, by a bolt 63. Slide 58 is adjustable axially in carrier 64 by screw 68, spring 76 preventing backlash, and so adjusts the carrier lengthwise of shaft 4 to a position appropriate for the blades, graduations on slide 58 indicating the adjustment. Carrier 64 is pivoted to a link 80 fixed to a pin 82, and link 90 pivoted to an eccentric pin 92 is adjustably secured in a graduated slot 88 in the carrier by a nut 86 and screw 84 journalled in the link. Guard 54 is normally urged to the right, Fig. 3, by spring 94 to a limit determined by adjustable stop 96. As the rear part of the heel of the shoe is offered to the blades the arrangement of links 80, 90 and carrier 64 permits the guard 54 to move yieldingly to the left, against spring 94, the adjustment of screw 84 in slot 88 determining the path of carrier 54 in accordance with the style of the shoe being trimmed. Swinging of handle 118 causes the eccentric pin 116 to bind on the stem 114 of the heel support 102, so as to lock the stem on a cylindrical split bar 104 and to lock the split bar in a bore 112 in the frame. Specification 246,136 [Class 17 (1)] is referred to.

Abstract: 811,092. Pneumatic conveyers. SVENSKA FLAKTFABRIKEN A.B. June 19, 1957 [June 20, 1956], No. 19311/57. Class 78 (1). In a conveying plant in which the material is drawn into the plant through a nozzle consisting of two concentric tubes and equipped with throttling means for automatically governing the air supply in accordance with pressure variations occurring on the suction side of the system, an extension tube is connected to the lower end of the outer tube of the suction nozzle and projects to such an extent below the inner tube of the nozzle that when the air supply is at a maximum, the sub-pressure at the mouth of the tube will be insufficient to lift the material through the extension tube. The lower end 1, Fig. 1, of the conduit 32, Fig. 3, is surrounded by a concentric tube 2, the upper part of which is connected to a chamber 3 and the lower part of which has a tubular extension 12. Inlets 4, 9 for air are provided in the wall of the chamber. The amount of air admitted through the aperture 4 is controlled by a damper 5 which is pivoted at 5b and connected by a rod 8 to a membrane 7. The membrane separates the chamber 3 from a space 13 which is connected with the suction side of a fan 35 by a pipe 38a. A spring 6 tends to hold the damper 5 in open position. The area of the inlet 9 is varied by moving a sliding door 10. The tube 12 projects to such an extent below the mouth 1a of the conduit 1, that when the air supply is at a maximum, the sub-pressure at the mouth 1a is not sufficient to lift the material through the tube 12. The conduit 32 is connected to a separator 33 from which the air passes through a pipe 34 to the fan 35 and the grain passes through a bladed rotor 37 into a pipe 36 leading from the fan 35. The pipe 38a contains an electromagnetic valve 39, the controlling circuit of which contains one or more contact breaking means 43. The means shown is actuated by a volumetric flow governor 40 and a discharge controller 44. After the quantity of air necessary for the calculated capacity has been adjusted by moving the damper 10, the inflow of material is regulated by the damper 5. When the quantity of transporting air falls below a value sufficient for the efficient operation of the system, the governor 40 moves to a position in which it actuates the contactbreaker 43 through the lever 42 to close the valve 39. As a result of this the damper 5 will descend to a position in which the aperture 4 is open fully and no material will be sucked up the tube 12. Specification 700,742, [Group XXIX], is referred to.
