Abstract: The milk weight is accurately determined by a vertical elongate float (6, 46) in the measuring container (1) cooperating with a stationary switch (10). This switch actuates the supply (3) and discharge (5) valves in the container when the float reaches its uppermost position and at the same time issues a signal to a registration counter (not shown) for the milk quantities received in the container.The sampling device either has a sample holder (8) below the measuring container (1), comprising a sample receiving volume (11) with open upper end, or an aperture (52) in the discharge valve (49) seat (50). Thereby in operation a proportional portion of the milk quantities passing through the measuring container (1) is collected in a mixing beaker (23), from which a sample bottle (28) may be filled.

Abstract: The invention relates to a conveyor chain intended for use, for example, in wood transporters. In order to be able to securely fasten the sleeves and the trunnions of the chain to their side plates, preferably by welding, projecting edge flanges are formed in the side plates so that the weld in each case is left in the trough formed by the edge parts.

Abstract: The specification describes a method and arrangements for operating fluidized bed combustors in particular boilers. In the described method and arrangements thermal energy carried away from the combustor by the flue-gas emitted therefrom is recuperated by passing the flue-gas through a scrubber in which it is scrubbed with water. The scrubbing water subsequently being used to pre-heat fluidizing gas fed to the fluidized bed in the combustor and/or working fluid fed to the boiler. Additional description is given of using a heat exchanger through which both flue-gases from the combustor and the working fluid fed to the combustor are fed such that the heat carried away from the combustor in the flue-gases is given directly to the working fluid fed to the combustor. In the described method and arrangements the fluidizing gas may be charged with water vapor and/or steam easing control of the bed.

Abstract: Leaks in fluid conveying pipe-lines, in which the noise from the escaping uid at the position of the leak creates sound waves are detected by at least one sound sensor and, at a known distance from it, a sound reflector, both of which are in direct contact with the fluid. The sound sensor receives the directly incident sound waves, and also the reflected sound waves from the sound reflector. The received signals are evaluated using an autocorrelation function.

Abstract: This apparatus comprises, in combination, two similar devices disposed in opposite directions. The devices are adapted to be fixed respectively to the two opposite wheels of a vehicle and parallel to the latter. Each device comprises a first rigid hollow tubular bar and a fixing structure for fixing the bar to a projector carrier. A structure inside the bar projects a beam of light longitudinally inside the bar. The beam is reflected at one end of the bar by a mirror which is rigid with a screen and so disposed as to project the beam transversely toward the screen pertaining to the opposite device. The mirror is mounted on the first bar of at least one of the devices so as to be movable toward or away from the fixing structure. A structure for receiving a sub-assembly for inspecting the pivot and castor angles of the vehicle wheel is provided. An apparatus for measuring the camber angle of the vehicle wheel is also provided.

Abstract: The present invention relates to a vacuum controlling device wherein a vacuum can be obtained by jetting compressed air, a predetermined vacuum state can be automatically confirmed and further the vacuum state can be quickly released by switching compressed air.

Abstract: Arranged in succession on a common optical axis is a laser, a modulator for shifting the frequency of light produced by the laser, an optical system for forming two light beams, a system of markers formed on the surface of a specimen being tested and a recorder of an interference pattern resulting from the interference of light scattered by the markers.

Abstract: The subject of the invention is a suspension device for a helicopter, intended for reducing the vibrations caused by its rotor. The main transmission box of the rotor is supported at the top by a set of oblique articulated bars and is bolted at its bottom to a diaphragm made of thin sheet metal, which can be deformed by bending, but not by shearing in its plane. Flexible arms arranged radially and supported by fixed mountings are articulated to the foot of the oblique bars and to the bottom of the transmission box; they each carry, at the end of a lever, a swinging weight acting by the effect of inertia.

Abstract: The invention relates to a composite polymeric material suitable for biological and medical applications and to the method for preparation thereof. The composite material consists of 1-99 wt. % of hydrophilic polymer or copolymer based on methacrylic or acrylic esters, 1-99 wt. % of fibrillar collagen, and up to 2.5 wt. % of a crosslinking agent, based on both polymeric components. The composite material may further comprise biologically active compounds and other auxiliary materials, as fillers and/or plasticizers. The composite material is prepared by dispersing the fibrillar collagen in a solution or a highly swollen dispersion of the synthetic hydrophilic polymer or copolymer in a lyotropic agent and the subsequent removal of the lyotropic agent, thus forming a matrix of the synthetic polymer or copolymer penetrated by fibrillar collagen or vice versa. The composite material may be applied on a solid support or reinforced with glass, plastics, cellulose, or metallic materials.
