Abstract: A B S T R A C T        An apparatus for controlling the movement of a movable tail-gate hinged to a tipping body of a vehicle. A collapsible toggle linkage is pivotally connected at one end to a flap adapted to bear against the tail-gate and the opposite end of the linkage is pivotally connected to a support secured to the vehicle.  The toggle linkage is moved between erect and collapsed conditions by a piston and cylinder assembly, the piston rod of said assembly being connected to the interconnected ends of the toggle linkage by a bracket.  The bracket serves as a stop to prevent outwardly collapsing movement of the toggle linkage.  The tail-gate can be maintained in a closed position independently of any forces exerted by the piston and cylinder assembly.

Abstract: Title of the Invention TREATMENT OF WATER VAPOR GENERATED IN CONCENTRATING AN AQUEOUS          UREA SOLUTION     Abstract of the Disclosure A process for treating water vapor generated in concen-trating an aqueous urea solution wherein a urea synthesis effluent containing urea, unreacted ammonium carbamate and water from a urea synthesis zone is subjected to a plurality of decomposition stages, the pressures of which stages are stepwise reduced to decompose and separate substantially all of the unreacted ammonium carbamate from the aqueous urea solution.  The aqueous urea solution which still contains small amounts of ammonia and carbon dioxide is concentrated to obtain crystalline urea or molten urea substantially free of water. The water vapor generated in concentrating said aqueous urea solution which contains small amounts of ammonia and carbon dioxide is cooled for condensation thereby forming a dilute aqueous ammonium carbamate solution which is subjected to rectification under a gauge pressure below 25 kg/cm2 to distil off a gaseous mixture of water vapor, ammonia and carbon dioxide, introducing the gaseous mixture into the unreacted ammonium carbamate decomposition stage using rectification under substantially the same pressure as the pressure of the rectification for the dilute aqueous ammonium carbamate solution to remove the water vapor from the gaseous mixture, and recover-ing the resultant ammonia and carbon dioxide together with a gaseous mixture of ammonia and carbon dioxide which is generated in the unreacted ammonium carbamate decomposition stage.

Abstract: Abstract of the Disclosure An apparatus is known for loading documents enclosed in jackets having laterally projecting shoulders supported by conveyor belts into a container with a U-shaped cross-section.  These jackets are moved into this container through one of the two open ends thereof in such a manner that their laterally projecting shoulders come to rest on the upper edges of the side walls of the container.  Such a way of container loading cannot be applied in machines wherein the articles, such as letters, are not enclosed in such laterally supported jackets but are carried on their bottom edge by a suppor-ting plate and wherein the containers are only open at the top.  Indeed, in this case the articles necessarily have to be introduced in the container through the open top.  The present invention therefore provides an apparatus of the above type which enables articles to be correctly loaded in a container through the one open side thereof.  This is achieved due to the fact that the present apparatus includes means to effect a relative displacement between the container and the supporting means in such a way that the articles carried by the supporting means are first introduced in the container, at least par-tially, through the open side thereof and come to rest against an inside part of the container.  Afterwards the articles are discharged into the container while the supporting means are removed from the container.

Abstract: ABSTRACT OF THE DISCLOSURE           A self-propelled truck has a rotatable turret on which an articulated and nested assembly of frame members and a scaffold is mounted for transport.  The turret and assembly can be operated to place the frame members in position to define a vertically extending portion outwardly of one side of the truck to extend, for example, downwardly of the side of a bridge on which the truck is located.  The scaffold then extends horizontally from the lower end of the vertical portion and may be swung horizontal-ly to extend either parallel to the side of the bridge or to extend inwardly under the bridge.  The scaffold is also vertical-ly movable and wheeled stabilizers of the truck can hold the same against tilting while permitting movement of the truck across the bridge with the assembly extended as described.

Abstract: ABSTRACT OF THE DISCLOSURE           An eccentric drive mechanism comprising at least one out-of-balance mass secured to a driven shaft and at least one ad-ditional mass adapted to rotate upon the shaft in relation to the out-of-balance mass, and to be locked to the shaft.  In known sim-ilar eccentric drive mechanisms, while it is quite a simple matter to vary the operating frequency by altering the r.p.m. of the out-of-balance mass, no satisfactory way of altering the exciter force has been found, that is, of displacing the out-of-balance mass and the additional mass in relation to each other.  Any adjustment of these two masses in relation to each other by means of drives such as planetary or helical drives greatly increases the cost and com-plexity of the mechanism.  This invention provides an eccentric drive mechanism which is of rugged and reliable design, and which provides for simple and rapid adjustment of the additional mass in relation to the out-of-balance mass, for the purpose of adapting the mechanism to given operating conditions.  This is achieved in that the shaft has an offset arranged eccentrically of a longitu-dinal axis (Mw) thereof. The additional mass is mounted rotatably upon the offset, the additional mass being connected to the shaft by at least one spring element acting in a peripheral direction.          At least one locking means is provided, the at least one locking means adapted to be actuated while the shaft is rotating so as to produce a releasable connection, secured against rotation, between the said shaft and the additional mass.

Abstract: ABSTRACT OF THE DISCLOSURE      A process for preparing diene hydrocarbons involving an oxidizing dehydrogenation of paraffin or olefine hydrocarbons at a temperature within the range of from 400 to 700°C in the presence of an inert diluent and an oxidizing agent in a fluidized bed of a catalyst. The process is conducted in a reactor having at least two sections partitioned vertically and communicating with each other in the upper and lower parts of the fluidized bed of the catalyst. The catalyst is directionally circulated from one section into the other while being subjected to reduction in the reaction of said oxidizing dehydrogenation upon its co-current movement with the hydrocarbons, followed by desorption of the reaction products from the catalyst upon its counter-current movement with the inert diluent, and to an oxidizing regeneration upon the co-current movement of the catalyst with the oxidizing agent. In the section where the desorption occurs, the cata-lyst concentration should exceed its concentration in the other section by a value ranging from 20 to 1,200 kg/m3.     The process according to the present invention makes it possible to prepare diene hydrocarbons in a single reactor, wherein there are combined the reaction of dehydrogenation of hydrocarbons and the catalyst regeneration. As a result, the process scheme is simplified, the catalyst losses are mini-mized and the production costs are reduced.
