Abstract: An element intended for connection to a shaft arranged in a bore in the element comprises two elastically deformable portions created by providing slots perpendicular and parallel to the axis of the bore, respectively. The portions each comprise a part of the wall of the bore and are arranged symmetrically with respect to the bore. Screws are used for deforming the portions so that a shaft situated in the bore is clamped to the element.

Abstract: A bait container, particularly useful with crustacean (lobster or crab) traps is formed with an apertured side wall in which the apertures comprise at least 35% of the surface area of the side wall. The apertures for any container are usually uniform in size and the range of aperture size is from about 250 to about 1000 microns. The size and distribution of the apertures prolongs bait life due to the controlled release of bait from the container and the added protection against unwanted predators such as arthropods. Furthermore the bait container permits the use of emulsified or minced bait produced from previously undesirable material, such as discards and non-edible fish parts taken from the fish processing industry.

The flange (6) is provided with attachments holes (7) and lugs (8) adjacent these, whereby the side surfaces of the lugs (8) are in level with the side (10) of the outer race ring (5), which shall engage the attachment surface of the vehicle, the trailer or the like.

Abstract: An arch-beam structure for use in combination with a culvert or the like includes a panel, which is cast or placed on the usual metal culvert conduit, the panel covering the top of the conduit, and having arms extending horizontally outwardly beyond the sides of the conduit for the purpose of transferring loads occurring on the panel-conduit system to the soil at the sides thereof, confining and thus increasing resistance to failure in the area of the soil or backfill materials adjacent to the structure.

Abstract: A method of controlling and selectively reducing the permeability of zones in an oil-bearing underground formation which have higher permeabilities than the surrounding zones by injection of exopolymer producing microorganisms into the oil-bearing formation is described. The exopolymer production of the microorganisms used in the method is controlled by regulation of the availability to the microorganisms of a compound such as sucrose which triggers exopolymer production.

Abstract: The invention relates to a device for performing rotational movement and comprises a rotatably element such as a cog-sector (3) or the like, arranged in a housing (1). The sector can easily be connected to rotatable machine elements of various kinds by being provided with an easily exchangeable coupling element (7) which can be displaced axially through a bore in the sector and through two bearings (8, 9) and be detachably fastened to the cog-sector by e.g. screws (14, 15) provided in threaded bores in the sector and abutting radially directed support surfaces in recesses in the element (7) between the bearing surfaces of the bearings (8, 9).

Abstract: A plurality of memory sections is provided each storing binary data to be employed for refreshing picture elements of a thin-film EL matrix display panel on successive frame time periods constituting an integration time period. The number of frame time periods in an integration time period corresponds to the number of different shades to be displayed on the panel. The binary data stored in each of the memory sections differs. Thus, when the binary data in the memory sections are read out on successive frame time periods, some of the picture elements on the panel are refreshed more than others during the integration time period. Accordingly, the eye of the viewer receives more light from some picture elements than others during each integration time period which results in the relative brightness levels and, therefore, the shades of the picture elements to vary.

Abstract: The invention pertains to a hub bearing unit for vehicles, trailers and the like, which unit comprises an inner race ring, an outer race ring (1) and rolling bodies disposed therebetween, whereby the inner and the outer race ring (1) respectively are mounted to the wheel and to the vehicle. The invention is characterized by a ball joint (7) which cooperates with the suspension attachment (3) of the vehicle and is arranged directly onto or in the outer race ring (1).

Abstract: A nut which is lockable on a threaded element comprises two annular parts (1, 2) connected by preferably resilient members (5). Locking takes place by tightening a screw (6) arranged in a threaded bore in one nut part and abutting against the other nut part. During tightening of the screw, the parts (1, 2) are displaced and/or skewed in relation to each other whereby locking takes place on the thread.

Abstract: The invention relates to an apparatus incorporating a planetary gear set with a shaft (7) connected to a planet wheel support (6), and a shaft (8) connected to a sun wheel (5), one of the shafts (8) being connected to a rotor in a device (9) for providing a torque. In order to be able to use the apparatus in a favorable manner in for example a servo assisted system with a steering wheel (10) and a steering member actuated by the steering wheel via a step-up gear, the stator part of the device (9) for providing a torque is connected to the other one of the shafts (7) in the planetary gear so that this shaft takes up the reactive torque which is established in the device during operation.

Abstract: The invention refers to a ball joint for suspension of wheels of motor cars and the like. It is characterized thereby that the attachment portion which extends from the very ball is designed with or provided with a fixed mounting flange.

Abstract: The invention relates to a means for mounting a hub bearing unit to the spring strut (13) of a vehicle. The means is characterized thereby that it (11) incorporated an open, box-like end, which is intended to be thread over the hub bearing unit and to be connected to this by means of bolts (7). The hub bearing unit thereby will be connected to the mounting means at both sides (10).

Abstract: A method and apparatus for microencapsulating an electroluminescent phosphor with an extremely thin coating. The process involves vaporizing a poly-para-xylylene, pyrolyzing the resulting vapors to form reactive monomeric radicals, and then passing such vaporous radicals to a vacuum deposition zone where they contact tumbling particles of an electroluminescent phosphor under vacuum conditions. As the particles are being coated, they are sifted by means of a screen. The reactive monomeric radicals deposit on the tumbling particles, are adsorbed by the particles, and polymerized into a very thin coating on the surfaces of the particles.

Abstract: A method and apparatus for the provision of cooling through the utilization of aerosol sprays is disclosed. The hot water output of a load device is stored until low ambient temperatures exist, whereupon the hot water is atomized and exposed to the ambient air to be cooled thereby. A spray cooling system can also be combined with an artificial ice making system to provide even lower load device input temperatures. Specialized insulating devices can be used in connection with the artificially made ice to decrease the heat transfer between the ice and the ambient air during warm weather.
