Abstract: ABSTRACT      A vertical radiation tank for gaining heat from process gases of ash forming, carbon containing fuels, comprises a vessel provided inside its jacket with diaphragm pipe walls traversed by a coolant.  The walls bound a flow space to be traversed by process gases, the space having at the top a central inlet for the gas, on the lower side an inverting space for inverting the direction of flow of the gas and, adjacent the inverting space, an outlet for the cooled gas.  The inverting space is bounded by a water space for capturing the locally separated ash particles.          In the present invention, the diaphragm pipe walls comprise a cylindrical, first diaphragm pipe wall concentric with the jacket of the vessel and covering the length of the flow space and the inverting space, a plurality of second pipe walls radially arranged inside the first pipe wall, a funnel-shaped, third diaphragm pipe wall bounding the radial pipe walls on their underside, and a short, cylindrical fourth diaphragm pipe wall adjoining the funnel-shaped diaphragm pipe wall.  The third and fourth diaphragm pipe walls are formed by pipes branched from the first diaphragm pipe wall.  The cylindrical first diaphragm pipe wall is formed by U-section pipes lying wholly or partly side by side, one limb of which at the top is connected with an annular collecting duct for the water supply and the other limb is connected with an annular collecting duct for the water outlet.          The radial second pipe walls are formed by a plurality of co-planar U-section pipes, one limb of which at the top is connected with a collecting duct for the water supply and the other limb is connected with a collecting duct for the water outlet.  With this arrangement, the overall heat exchanging surface per unit of volume of the tank is increased, so that the dimensions of the tank can be reduced.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention relates to an apparatus for the administration of medications. The apparatus includes a dosing unit and a control unit associated therewith.          The apparatus also includes a safety system which prevents a harmful overdose when the person using the apparatus is unable to take action. For this purpose, the safety system initiates a safety measure, (such as turning off the dosing unit, switching the dosing unit to a reduced administration rate (so-called "emergency rate") and/or setting off an alarm) in the event that a checking procedure is not triggered by the patient within a predeterminded time intervall or after the administration of a specific quantity of medication. Starting times based on the clock time and generated by a master clock can be pre-programmed, for example, as a reminder of the patient to take his or her meals. In an embodiment, a signal device is activated as soon as a prescribed qualifying interval begins. In particular, in the case of insulin therapy the apparatus prevents a dangerous hypoglycemia from occurring in the patient as the result of long lasting insulin overdose, for example, during his or her sleep.

Abstract: SEMICONDUCTOR INTEGRATED CIRCUIT            Abstract Logic arrays which apply outputs to logic circuitry are made to exhibit improved noise characteristics which, in turn, improve performance of the logic circuitry.  The improvement is achieved by providing a distributed ground throughout the logic array to provide local closed loop paths for discharge currents generated in the array.  In this manner, discharge currents are not allowed to flow in ground or power BUSES and so do not affect the driven logic circuitry.

Abstract: ABSTRACT     A vehicle particularly suited for loading and transporting elongated articles such as trees.  The vehicle has a chassis with one pair of wheels on one side of the chassis and another pair of wheels on the other side of the chassis.  A cab and power supply means are mounted from the chassis over the one pair of wheels.  A grapple is mounted at about the center of the vehicle and movable sideways over the other side of the chassis to pick up a bundle of trees alongside the vehicle.  The grapple picks up the bundle at about its center of gravity and moves the bundle over the chassis between the wheels to transport the trees.          The first pair of wheels is fixed to the chassis via a first beam while the second pair of wheels are mounted on a second beam which is pivotally mounted to the chassis.       The operator's cab can be mounted on tracks to move to the loading or other side of the chassis for a better view of loading and then moved back out of the way to make room for the load on the chassis.

The short first leg of the spring is positioned within the second slit of the polar member and the second leg of the spring is urged against the dust door to effect torsion of the spring.  In the method of assembly, the wide and narrow slits of the dust door polar member sequentially receive the first short leg of the spring and twist the spring in a clockwise direction, to urge the second long leg against the dust door to effect torsion.  This dust door polar member, dust door spring assembly and method for manufacturing and assembling the dust door spring assembly provide more efficient production and automated assembly of tape cassettes.

Abstract: ABSTRACT     The application describes digital signal processing of radar video signals to provide an optimum display.  Three interacting components of the system are further described in detail:  a global mean estimating circuit, a statistical analyzer circuit, and a dynamic range compression circuit.          The global mean estimating circuit determines the mean of the amplitude distribution of video signals over a wide section of the display as opposed to a local mean of signals.          A local mean of signals is the mean of the amplitude distribution of video signals occurring in the near vicinity of a point on the display.  The statistical analyzer circuit evaluates the amplitude distribution of video signal samples and controls the gain of the signal path so that the variance of the sampled amplitude distribution follows the variance of a model distribution.  The dynamic range compression circuit functions to compress the range of amplitude distribution in a manner to provide maximum information from the display.
