Title: Improvements relating to the treatment of oils
Inventor: JONGE ALBERT DE
IPC: C11C3/12
Filed: 1964-08-12
Abstract: Edible vegetable oils containing both linoleic acid and linolenic acid are selectively hydrogenated, so as to reduce the content of linolenic acid to at most 50% of its original value while retaining at least 40% of the original linoleic acid content, by treatment with hydrogen at 150-225 DEG  C. in the presence of a catalyst in which the active material is composed of at least 70% by weight of copper in structural combination (as opposed to simple mixture) with a more highly active metal, e.g. Ni, Pd, or Pt.  Prior to hydrogenation the oil may be refined, e.g. by desliming, neutralization, and/or bleaching; and subsequent to hydrogenation the catalyst and oil are separated by filtration with exclusion of air and/or heating to not more than 100 DEG  C., the oil then being washed with an aqueous acidic solution and/or a solution of a metal sequestering agent, e.g. the disodium salt of EDTA.  The oils which may be treated include soyabean, rapeseed, mustard, rubberseed, and wheatgerm oils.ALSO:Hydrogenation catalysts are described in which the active material comprises at least 70% by weight of copper in structural combination (as opposed to simple mixture) with a metal which is more highly active than copper e.g. Ni, Pd, or Pt.  The catalyst may be supported, e.g. on diatomaceous earth, silica gel, charcoal, or magnesium sulphate.  A typical catalyst comprises Cu, Ni, Mg, and silica in the ratio 3.96:0.04:1.0:0.5.  The catalysts may be prepared by conventional methods which are described.

Title: Improvements in or relating to hydraulic control of fuel-tapping plant
IPC: B67D7/32
Filed: 1928-11-09
Abstract: 301,492. Martini & H³neke Maschinenbau Akt.-Ges., (Assignees of Explosionssicherer Gefõsse Salzkotten Ges.). Dec. 1, 1927, [Convention date]. Direct liquid-pressure apparatus. -Apparatus for delivering liquid fuel from a storage tank A by means of pressure water supplied by pipes d, c, is provided with a controlling device C in the water line comprising a pressure operated diaphragm &c. 14 carrying a slide valve 17 which is pressed upwards by a spring 19 and is connected by a rod 26 to a valve 30. When the delivery cock B is opened and a valve C<2> raised by means of a cable h, pressure water from the pipe d passes by pipes 8, 10 and a non-return valve 11 to the upper side of the diaphragm, forcing the diaphragm, and the valves 17, 30, downwards, so that the pressure water passes from the pipe d through an adjustable reducing valve 32 and ports 29 to the pipe c and tank A. The downward movement of the diaphragm withdraws a spring-pressed rod 22 from a valve 12 and allows water to pass from pipes d, 13 into the chamber 2. At the same time a weighted lever 37 falls and closes the valve 11. When the tap Band valve C<2> are closed, the pressure in the pipe c and chamber 1 increases and, assisted by the spring 19, lifts the diaphragm and valves 17, 30, closing the ports 29 and raising the ports 18 of the valve 17 above the top of the annular wall 15, so that the pressure water in the chamber 1 may escape to an atmospheric pipe 6. The rod 22 closes the valve 12, and the lever 37 is lifted to open the valve 11 and allow the water in the chamber 2 to escape to a waste pipe 9.

Title: Improvements in or relating to automatic sorters for faulty stampings or other partsof disc-like form
IPC: B23Q7/12
Filed: 1920-11-24
Abstract: 175,108. Evershed, W. J., and Evershed, C. Nov. 24, 1920. Sorting defective discs by travelling bands, discs, screws, and the like.-A sorting device for disc-like bodies consists of a conveyer comprising two opposed parallel members adapted to support the edges of a disc, one member being moved relatively to the other so that the disc travels along the conveyer and is rotated, all parts of its periphery thus coming into contact with the supporting-members, whereby an incomplete disc is rejected. The invention is particularly applicable to sorting stampings for making closure-discs for milk-bottles. In one form discs D, Fig. 1, are fed by a belt A to two narrow supporting-bands C situated close to side guides B, and driven at different speeds. In another form, Fig. 3, the discs are fed horizontally against a back-stop F and on to the threads E<1> of vertical twin screws E rotated at the same speed in the same direction or at different speeds in opposite directions. The discs may also be fed on to the edges of vertical discs rotated at . different speeds and situated between guides such as B, Fig 1. Instead of these guides the edges of the vertical discs and the bands C, Fig. 1, may be of L-section. In a further modification the discs may be fed edge on between two spring-pressed members having a limited movement towards each other and made to travel at different speeds. In each case a perfect disc is carried forward and delivered and a faulty one fails to find the necessary support and is rejected. A cross belt G, Fig. 1, driven by vertical spindles II turns over any discs fed edge on by the band A.

Abstract: 1,018,293. Cigarette making machines. K. KÍRBER. May 4, 1962 [Sept. 15, 1961], No. 33253/61. Heading A2C. A control device responsive to an air flow for testing rod-like tobacco articles, comprises a pivotally suspended baffle plate 39 against which a current of air dependent on the testing of the articles is directed by an air nozzle 40 disposed beneath the pivot axis 28 of the baffle plate. A diaphragm 34 is fastened to the baffle plate 39 and extends on the side of the baffle plate opposite to the nozzle so that the baffle plate is biased towards the nozzle. A photo-electric control system including a light source 35 and a light sensitive element 36 is placed so that movement of the baffle plate 39 and the diaphragm 34 controls the response of the light sensitive element according to the displacement of the baffle under the influence of the air directed against it by the nozzle, and thus according to the testing of the articles. The pressure from the nozzle 40 should be sufficient, during testing of normal articles, to cause the diaphragm to prevent light reaching the lightsensitive element 36 and correct adjustment is achieved by a counterbalancing weight 32, movable in a slot 31 or, alternatively, by employing a semi-circular plate mounted on the same axis as the baffle plate (Fig. 2, not shown) one half of the plate being slightly heavier than the other and acting as a diaphragm.

Title: Improvements relating to the catalytic cracking of hydrocarbons
IPC: B26D1/00
Filed: 1964-08-17
Abstract: The heat supplied for the catalytic steam reforming of gaseous or liquid hydrocarbons in a tube furnace, optionally with air, is divided into two parts, one for heating the furnace and and other for heating the flue gas effluent therefrom, such that the steam requirement is generated solely by the flue gas and the reactants are preheated either by means of the product gas alone or by means of product and flue gas; part of the total fuel requirement may be burned in the effluent flue gas; alternatively some hot flue gas withdrawn from the furnace may be added to further flue gas cooled in heating the furnace.  In Fig. 2, gasoline with a boiling limit of 180 DEG  C. and air are introduced by pipes 1, 2 respectively into burner 3 of tube <PICT:1003538/C4-C5/1> furnace 4; the flue gas exit temperature is controlled either by (i) withdrawing at 34 some flue gas not, or only partially, cooled by heat exchange with reaction tubes 5 and mixing it via pipe 35 with the remaining flue gas in pipe 7 or by (ii) supplying a branch flow of fuel gasoline by line 31 into additional burner 32 with air from pipe 33; flue gas temperatures of 965-1400 DEG  C. are thus obtainable; the gas passes through steam boiler 8 and is discharged at 10; the total product gas, e.g. at 785 DEG  C. is thus available for preheating steam and air in 17, e.g. to 700 DEG  C., and then for pre-heating boiler feed water in 36, e.g. to 80 DEG  C., before leaving the plant via pipe 22; steam in pipe 23 generated by the fuel gas preheats the cracking gasoline in exchanger 24.
