Patent DK-21987-A (DK)
Inventor: HOLMBERG GLENN
IPC: B01D33/03
Filed: 1987-01-16
Abstract: A method and an apparatus for separating bodies from a liquid in which the liquid is passed through a filter and the bodies to be separated are accumulated on the filter. The filter forms an upper bounding limit of a space therebeneath which is alternately subjected to pressure and vacuum relative to the ambient region above the filter. This is achieved according to one embodiment by producing a reciprocal movement of the filter in the form of an oscillating or pendular movement. The pressurization in the space produces separation of the bodies accumulated on the upper surface of the filter to facilitate their discharge from the filter. The separated bodies can be assisted for discharge by mechanical elements and/or by producing wave motion in the liquid.

IPC: B08B3/02
Filed: 1996-04-24
Abstract: For washing, flushing and drying objects, such as catering carts (23, 24), for use when transporting meals to and from a kitchen to an aircraft, the catering carts are placed inside a cage (4) which is arranged in a washer, in which washing and drying take place during centrifugation. For centrifugation to take place at the greatest possible speed with the greatest possible safety, the catering carts are placed in a cage (4) which is preferably box-shaped. The cage is centrifuged together with the carts. The washer has two doors (2, 3), one door being used for filling the washer with soiled catering carts, the other door being used for taking cleaned carts out of the machine, which ensures high efficiency, as the machine can be in almost continuous operation. During flushing in the washer, vertically arranged washing nozzles (6) move in a horizontal plane so that these operate in synchronism with the rotary movement. The invention thus provides a washer which operates quickly and effectively and observes strict safety and cleaning requirements.

Filed: 1938-01-04
Abstract: 489,150. Magazines for automatic firearms. RHEINMETALL-BORSIG AKT.-GES. Jan. 4, 1938, No. 212. Convention date, Jan. 4, 1937. [Class 119] A magazine 2 for an automatic firearm is disposed laterally of the gun, the magazine being opened by swinging the upper wall 3 of the magazine in its own plane about a pivot 13, this action resulting in the retraction of the magazine follower 4 and the compression of the magazine spring 5. The upper wall 3 extends downwardly at one side to enclose a gap 2a in the lower wall of the magazine through which empty cartridge clips may fall when the magazine is open. The follower 4 has a block 4a guided in a channel 2b, the block having a notch so that the follower may be held in retracted position by a pawl 18 which is released by a cam surface 3b on the wall 3 when the latter is moved to close the magazine.

Title: Improved means for slewing and dipping the head lamps of motor vehicles
IPC: B60Q1/124
Filed: 1930-01-02
Abstract: 347,730. Directing vehicle lamps. HEIMBERGER, H., 56, Gartenstrasse, Reutlingen, Germany. Jan. 2, 1930, No. 214. [Class 75 (iii).] Hydraulic means for swivelling and dipping motor car headlamps comprise a liquid cylinder 2 which is fitted with a piston 3 operated by the steering lever 4 and is connected by pipes 5, 6 to liquid cylinders 7 containing double pistons 8 connected by racks 9 engaging pinions 11 on the head-lamp shafts 10. The pinions 11 both have untoothed portions of their peripheries provided with a notch 12 engaged by a spring-pressed nose 13 in their casings so that the pinions can only rotate in opposite directions. A movement of the steering wheel causes the rotation of the shaft 10 of the head-lamp on the inner side of the curve being turned. The shape of the notches 12 is such that when the steering wheel returns to its normal position the turned shaft also returns to its normal position without any movement of the previously stationary shaft being produced. The shafts of the head lamps are slightly tilted so that the swivelling of a lamp will be accompanied by a dipping movement. The piston 3 may be operated from the steering-wheel through a crank and transverse guide arranged to give a more rapid operation at the commencement of the turning movement. A byepass conduit 22 fitted with a shut-off cock 23 allows the swivelling mechanism to be put out of action during daylight. The lamps are dipped simultaneously by means of similar piston and rack devices 28 connected by conduits 29 to cylinders 24 fitted with hand or foot actuated pistons 25. By turning three-way cocks 26 the cylinders 24 may be put into communication with the cylinders 7 so as to allow the lamps to be swivelled by the operation of the pistons 25. The dipping operation may also be effected by the pressure of the lubricating oil supplied from a reservoir 33 by a pump 30 to an air vessel 31 and directed by a multiple-way cock 34 to one side or the other of the cylinders 28. Fig. 4 shows the lamp trunnions 41 carried by a rocker 40 engaged by nuts 39 mounted on oppositely threaded screws 38 carried by a head 37 on a hollow shaft 10b which encloses a shaft 10a carrying a pinion 35 meshing with pinions 36 on the screws 38. When the shaft 10a is turned a dipping movement only is imparted to the lamp but when the shaft 10b is turned the lamp is dipped and swivelled simultaneously.

Title: Improvements relating to the production of non-poisonous town gas
IPC: C10K3/04
Filed: 1935-01-04
Abstract: 438,757. Gaseous mixtures. NON- POISONOUS GAS HOLDING CO., Ltd., Vaduz, Liechtenstein. Jan. 4, 1935. No. 380. Convention date, Jan. 4, 1934. [Class 55 (ii)] In the production of a non-poisonous town gas from a fuel gas by subjecting the gas to a single-stage water-vapour catalysis to convert the carbon monoxide into dioxide and hydrogen, the fuel gas is prepared free from hydrogen sulphide and with a heating value in excess of the usual value so as to produce a final gas approximating to the standards usual in ordinary town or coal gas. The process is operated without the removal of carbon dioxide or the addition of extraneous gas. The catalysis is effected at a temperature between 350-500‹ C. In examples, a retort gas, carburetted water gas and coal gas are prepared of total heating values of 4820, 5600 and 4503 calories per cubic metre respectively, and after the water-vapour catalysis gases of less than 1 per cent carbon monoxide content are obtained of heating values 4434, 4350 and 4255 calories per cubic meter in each case.

Title: Improvements relating to the shaping of metal tubing
IPC: B21D7/022
Filed: 1951-01-05
Abstract: 701,112. Bending tubes. DRAPER, F. C., HOBSON, J. F., and SANG, W. Dec. 12, 1951 [Jan. 5, 1951], No. 405/51. Classes 83 (2) and 83 (4). [Also in Group XXIX] A method of forming a bend in a metal tube comprises compressing the walls of the portion of the tube to be bent so that they approach one another to give a cross section which is concave towards the side which is to be the outside of the bend, bending said compressed portion on a former to the required curvature and then expanding said portion to the desired final shape by fluid pressure whilst it is confined in a die. The portion to be bent of a tube 1 is placed in a member 3 of a press and compressed by a member 4 to the shape shown in Fig. 6. After annealing the compressed portion is bent on a former 5 by means of a roller 10 mounted between the side arms 9 of a lever 8 which is pivoted at the centre of curvature 7 of the semicircular contour of the former 5. The roller has a convex profile 12 for co-operating with the concave profile 6 of the former 5. One end of the tubing is gripped in a chuck 15. The bent tubing is then annealed and inserted in the lower half 19 of a split die one end of the tubing being plugged by a plug 21 provided with a sealing ring 22 the plug being held in position by a split bush 23. The plug 21 has an enlarged head 24 engaging with a recess in the die for locking the plug in position. An hydraulic fluid inlet valve 25 is inserted in the other end of the tube and is retained by a split bush 27. The upper half of the die (not shown) is then lowered into position by hydraulic pressure and hydraulic fluid of low pressure is introduced into the tube (see Group XXIX) the air in the tube escaping by means of a bleed passage 33 in the plug 21. The bleed passage is controlled by a cock 34. When the bleeding is complete the cock 34 is closed and the tube is initially expanded by a higher pressure of fluid and the tube removed and annealed. For the final expanding operation the end of the tube in which the pressure valve is inserted remains free to slide in the die by replacing the split bush 27 with a round bush in which the tube is a sliding fit. The full hydraulic pressure is then applied and the tube wall is expanded into contact with the die walls after which the tube is removed and annealed. The bent tube may be tapered by introducing a taper into the die so that the tube is expanded to give the desired taper. The invention relates to large diameter tubes of thin wall construction for use as short elbows for petrol and oil tanks in aircraft, ducts, fuel and air distributing rings on gas turbines and musical instruments.

Abstract: 1,028,587. Erasing erroneous characters from documents; fraud-preventing. M. S. BUROS. Jan. 7, 1964 [April 24, 1963], No. 671/64. Headings B6A and B6P. To prevent errors in data processing due to erroneous magnetic character recognition data on a document such as a cheque, a solvent, which is solvent to the magnetic data but not to the inks of the signature, water mark &c. on the cheque, is applied to reduce the magnetic retentivity of the dissolved characters to such an extent that they are not read as characters by the processing equipment. The solvent may be applied by a dauber, and the dissolved parts of the erroneous characters are then absorbed by the dauber or distributed over a larger area or both. The original characters can still be deciphered although producing no recognizable signals, thus providing a protection against falsification Further, the correct characters can be typed over the original characters. A number of suitable solvents are described.
