Title: Injection moulding
IPC: B29C48/92
Filed: 1961-04-20
Abstract: 963,436. Injection moulding machines. DEUTSCHE SOLVAY - WERKE G.m.b.H. April 20, 1961 [April 21, 1960], No. 14227/61. Heading B5A. A process for the manufacture of injection moulded articles on known machines in which one or more screw conveyers are rotated to advance the material and are axially displaceable is characterized in that a work or energy measuring device is provided to measure the energy absorbed during rotation of the screw conveyer or conveyers or given off to the moulding material, this measurement being used to control the working cycle, so that when a defined amount of energy is reached the rotation of the conveyer is automatically or manually stopped and, if desired, the next working cycle is started. During rotation of the screw conveyer it is pressed back by the pressure of material collecting in the front part of its cylinder and is then moved forwards by hydraulic pressure to inject the material into a mould. This pressure may be applied on actuation of a switch by the screw at the end of its rearward movement, and the position of this switch may be adjustable to vary the injection capacity of the machine. Rotation of the screw may be restarted during or shortly after the preceding injection process. German Specification 858,310 is referred to.

The fabric 4, passed over feed rollers 3 is festooned over driven rollers 5 and passes over further rollers 7, 9 on to piles 10. Air is blown by fan 12 past a spray 14 of hot water and enters the chambers 2 through a grilled floor 6.  A part is directed through ducts 15, Fig. 2, into lateral passages 16 and over refrigerating elements 17, the mixture of descending cold air and rising warm air forming a fog in the central part of the chamber.  The atmosphere in the second chamber is regulated by controllable vents 11 and outlet vents 19 are provided in the roof of the first chamber.  In a modification, Fig. 3 and 4, a regenerative system is employed, the fabric passing over a conveyer belt 24.  Fans 12a pass the humid atmosphere into passages 16 and thence over heaters 26 and water troughs 27, or in the case of the rising atmosphere over refrigerating elements 17 or adjustable controls 28.

Title: Improvements in or relating to platinum-alumina catalyst
Inventor: BRENNAN HARRY MICHAEL
IPC: B01J23/40
Filed: 1955-05-23
Abstract: An alumina-supported platinum catalyst is prepared by adding an alkaline substance to peptized alumina in a sufficient quantity to raise the pH to between 8.5 and 12, maintaining the resulting mixture at this pH for more than one hour, separating the solid hydrous alumina, drying to a volatile content below 50 per cent by weight, impregnating with between 0.05 and 1 per cent by weight of platinum, and drying and calcining.  The peptized alumina may be an alumina hydrosol prepared by hydrolysing aluminium acetate or alkoxide, by digesting hydrous alumina in dilute acid, or by the process of Specification 552,053, in which amalgamated aluminium is digested in a dilute organic acid; alternatively amalgamated aluminium may be digested omitting the organic acid, the hydrous alumina formed being separated and peptized with dilute organic acid.  Suitable alkaline substances for adding to the peptized alumina are ammonium hydroxide, water-soluble amines, or quaternary ammonium hydroxides; sodium hydroxide or carbonate, potassium carbonate, or calcium hydroxide may also be used, but the alumina should then be washed free from alkali cations.  The mixture may be held at the alkaline pH at 50-250 DEG F. for 1-48 hours or for longer periods, e.g. 75-150 hours.  The slurry formed is filtered and the filter cake dried at up to 1200 DEG  F., preferably 150-400 DEG  F., for 1-24 hours.  Incorporation of platinum may be effected (a) by saturation with an aqueous chloroplatinic acid solution and subsequent addition of ammonium sulphide solution; (b) by saturation with a solution of aqueous chloroplatinic acid solution containing ammonium sulphide; or (c) by impregnation with a platinum solution containing a dissolved inorganic aluminium salt, e.g. the nitrate, sulphate, chloride, bromide or iodide, and also containing an organic solvent, e.g. acetone, methanol, ethanol or isopropyl alcohol or other wetting agent, e.g. sodium benzenesulphonate, a polyethylene glycol, or a glycol ether.  The catalyst is finally dried and calcined at 800-1200 DEG  F. in air, hydrogen, nitrogen or flue gas; it may be in the form of a powder, irregular fragments, or shaped bodies, e.g pellets.  The alumina in the final catalyst contains from 5-100 per cent of eta-alumina.  Examples 1-10 describe the preparation of catalysts and Examples (1) and (8) also describe hydrocarbon hydroforming tests for measuring the activity of the catalysts. Example (1) refers to regeneration of the catalyst by treatment at 850 DEG  F. and 300 lb. per sq. in. gauge pressure with nitrogen containing 2 per cent oxygen and 0.5 per cent water, and then with air containing 0.5 per cent water at 1050 DEG  F.  In addition to hydroforming, the catalysts are useful in other hydrocarbon conversion reactions, e.g. reforming, isomerization, hydrogenation, hydrocracking, dehydrogenation, oxidation, polymerization and condensation.  Specification 736,632 also is referred to.

Abstract: 694,685. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 25, 1951 [June 28, 1950], No. 15018/51. Class 98 (i).. In apparatus wherein a carriage supporting an X-ray tube and a fluorescent screen or photographic plate is driven by an electric motor lengthwise of a couch for the patient and is balanced by a counterweight, the motor, when in use, continuously supplies a torque which is sufficient to overcome inertia and friction and to move the carriage at low speed, increased speed being obtained by increasing the light pressure necessary for closing the operating switch of the motor. As shown, a couch 1 is trunnioned at 2, 3 in supports 4, 5, and can be tilted by a toothed segment 9 engaging a pinion 8 driven by a motor or a handle 7. A carriage 11 travels by wheels 13 on the frame 10 of the couch and carries an X-ray tube 21 mounted on a cone 20. A fluorescent screen 22 (not shown) is mounted in a position spaced from, and parallel to, the carriage 11, by means of an arm 15. Flexible cables 24, 25 are fixed to opposite sides of arm 15, pass over pulleys 26, 27, and are connected to a counterweight 23. Pulley 26 is driven by means of a motor 34 through gears 33, 32 and a dog clutch 35. A grip is provided on the fluorescent screen and has a switch mounted thereon, which when operated in one direction energizes the motor to move the carriage in one direction, and when operated in the other direction reverses the motor to move the carriage in the other direction. Increased speed is obtained by increasing the hand pressure applied to the switch. When the motor is not energized, clutch 35 is disengaged, and the carriage can be moved by hand.
