Abstract: A load-transporting method and apparatus involve use of a transport vehicle, preferably a straddle truck, having connected thereto a load carrier in the form of a frame which is capable of engaging a load and elevating the same with respect to a given surface on which the load initially rests when the load-carrier is raised with respect to this surface. The connection between the load carrier and the vehicle is such that once the load is engaged by the load carrier, the travel of the vehicle with respect to the load causes the load carrier to act through its connection to the vehicle on the latter in a manner which resists the travel of the vehicle and causes the load to move frictionally with respect to the above surface on which it initially rests, the kinetic energy of the travelling vehicle and the friction of the load with respect to the surface and/or the inertia of the load being utilized to bring about elevation of the load and the load-carrier with respect to the above surface.

Abstract: A device for reducing noxious emissions from carburetor engines of the internal combustion type, the body of which comprises at least one main passage designed for feeding a fuel-air mixture to the engine cylinders and has an emulsion passage. The main passage accommodates a throttle valve which divides it into an upstream throttle space and a downstream throttle space, as viewed in the direction of the fuel-air mixture flow. The emulsion passage communicates with the upstream throttle space substantially in the area where the throttle valve upper edge locates when the throttle valve is in the closed position and also communicates further, as viewed in the direction of the emulsion flow, via an adjustable throttle element with a chamber which communicates via an air passage with the upstream throttle space and via a passage with the downstream throttle space. The chamber accommodates a movable element adapted to move coaxially with the passage for the purpose of closing same.

Abstract: The flat sealing member of the device is forced against the end face of the mutually rotatable rollers by virtue of a bow-shaped projection having a triangular cross section and somewhat rounded off crest to provide a relatively linear contact. The above flat sealing member has a hollow interior space for a refrigerant and a lubricant to feed thereinto, both of them being then delivered to the zone of contact of the above projection and the end faces of the rollers. Such a system reduces wear on the rubber-coated roller surface and adds to the service durability of the whole unit.

Abstract: Proposed is a device for radiochromatographic analysis of mixtures of substances containing components tagged by radioactive isotopes, such as soft .beta.-isotopes comprising a chromatographic column, a detector of nuclear radiation and a chromatographic detector connected in series along the flow of the substance being analyzed.

The tube is provided with movable means for sequentialy cooling and heating the same and a light detector which is movable along the length of the tube. In operation, upon introduction of the portion of the mixture being analyzed into the column, with the heater interacting with the tube, the heater and cooler are moved so that by the time the last component of the mixture exits from the column, the cooler is in interacting relationship with the tube whereby the components of the mixture are frozen.

Abstract: Pyrolysis of hydrocarbon starting products is carried out in a cylindrical casing containing a liquid heat carrier at a predetermined level in the casing. The casing is split into a heating zone and a pyrolysis zone by a cylindrical baffle which extends a small distance below the surface of the heat carrier. A jet directs a gaseous heating agent onto the surface of the heat carrier in the heating zone. Another jet directs hydrocarbon starting products onto the surface of the heat carrier in the pyrolysis zone where pyrolysis products are formed.

Abstract: A method for testing cyclically operated mechanical members for defects comprises the steps as follows: a frequency range of at least two wideband electrical signals corresponding to the defects of the test member is selected; the modulus and phase of the resultant electrical signals is determined and the magnitude is accumulated using the value of the phase of that signal within a given number of rotational cycles of the test member; defect locations are determined using the maximal accumulated magnitudes of the resultant electrical signal and their corresponding phases. An apparatus to realize the disclosed method comprises at least two vibration pickups adapted to sense the vibration of the test member and coupled to the inputs of adjustable pass band filters which are operated to select a frequency range corresponding to the defects of the test member.
