Abstract: An improved base construction for a wheeled nestable shopping cart is provided by forming the base primarily from two U-shaped members. The first U-member has a planar portion disposed directly under the basket for supporting same, which portion terminates in downwardly directed rear legs which have the lower ends thereof joined to the rear wheel assemblies. The second U-member has the bight thereof forming the toe end of the base. The leg portions of this second member incline rearwardly and upwardly from the bight such that the free ends thereof are fixedly engaged with the rear legs adjacent the upper ends thereof. Side braces rigidly join the planar portion to the leg portions of the second member. This arrangement effectively prevents storage of goods on the base.

Abstract: A reversing mechanism for steerable propellers on ships wherein the direction of travel of the ship is controlled by the position of the steerable propeller. A selector switch is provided for controlling the direction of travel as well as directions forward and rearward such that when the direction of travel is to be reversed, the steerable propeller will be sequentially disengaged from the propeller driving mechanism and automatically pivoted through 180.degree. to effect a reverse operation without altering the position of the steering control. In other words, the position of the steerable propeller will be altered without altering the position of the steering control when the direction of travel of the ship is to be reversed.

Abstract: In an apparatus for the cutting, deburring or breaking of the side tooth edges of gears with one or two tools which are located on the side of a guide gear and which machine the aforesaid tooth edges. The guide gear meshes with the workpiece, and, in one embodiment, is constructed as a measuring gear. Prior to the actual machining operation, the distance between the axes of the pretoothed workpiece and the measuring gear is measured independently and is made visible, if desired, on an indicating device. In order to avoid incorrect measurement results due to burrs existing on the workpiece, the guide gear can, if desired, have recesses into which extend the burrs.

Abstract: A solar concentrator having an open framework formed as a geodesic dome. A rotatable support axle extends substantially diametrically across the dome and has the opposite ends thereof supported on the framework. The support axle defines a first rotational axis which is oriented to extend substantially parallel with the earth's North-South axis. A support post is hingedly mounted on the support shaft substantially at the midpoint thereof for permitting angular displacement of the support post relative to the support shaft about a second rotational axis which is perpendicular to the first axis. A dishshaped reflector assembly is positioned within the interior of the framework and fixedly secured to the support post. First and second drives effect angular displacement of the reflector assembly about the first and second axes, respectively, to permit tracking of the solar position.

Abstract: Apparatus for the storage of ice which includes a housing for storing pieces of ice. The housing is shaped in the form of a frustum, is interiorly thermally insulated at least on the sidewall and has a top feeding opening and a bottom outlet opening. The scratching-off device is positioned adjacent the bottom opening. The ice is scratched off and dropped continually downwardly toward a delivery station positioned below the scratching-off device and communicating with the bottom opening, where the pieces of ice are removed. The apparatus may also include a measuring device positioned adjacent the delivery station, with which a definite amount of ice delivered from the delivery station is measured out. Thus it is possible to remove pieces of ice stored smoothly, continually and efficiently.

The barrel-supporting cradle is vertically adjustable and clamp means are provided for engaging the barrel and the butt stock adjacent said cradles for firmly holding the rifle with respect to the support.This invention relates in general to an apparatus for adjusting the sights of a gun and, more particularly, to a gun sighting apparatus adapted to adjust the telescopic sight on a rifle.

Abstract: In the process for urea synthesis, an effluent from a reactor 2 containing urea, ammonium carbamate, excess ammonia and water is introduced in a first heater 3 to separate excess ammonia and to decompose ammonium carbamate, thereby separating them from the liquid phase; then the liquid effluent from the first heater 3 is introduced in a second heater 6 to separate the remaining excess ammonia and to decompose ammonium carbamate in the presence of starting carbon dioxide used as stripping gas, thereby separating them from the liquid phase; the liquid effluent from the second heater 6 is introduced into a urea solution purification step in which pressure is lower than in the above step; and the separated gaseous effluents from the first and the second heaters are returned into the reactor.

Abstract: An adjustable quadrangular base, such as for a framework assembling machine, including a group of four elongated rigid elements each having a rigid boxlike member fixed to one end thereof. The boxlike members all have a substantially planar upper surface thereon, which surfaces are all coplanar. An opening extends through each boxlike member parallel to the respective upper surface and perpendicular to the respective elongated element. Each elongated element slidably extends through the opening formed in the boxlike member fixed to one of the remaining elements, whereby two of the elongated elements define a parallel pair which extends in perpendicular relationship to a parallel pair defined by the remaining two elements. The elements can be relatively slidably displaced with respect to the other elements due to the slidable engagement between each element and one of the boxlike members, whereby the size of the square defined by the upper surfaces of the four boxlike members can be enlarged or contracted.
