Granted: 1981-10-20
Abstract: BATTERY CHARGER AND SURVEILLANCE SYSTEM     ABSTRACT OF THE DISCLOSURE            A battery charging apparatus has a control circuit which controls the rate of input of AC power through a synchronous switch -- a saturable core reactor, magnetic amplifier or a pair of anti-parallel silicon  controlled rectifiers.  The operation of the charger is such that the length of the charging program can be predetermined,and when the charging program is initiated a survelliance system functions to determine that the charging current during the program, and particularly at the end of the program, is within anticipated limits.  If the charging current is not within anticipated limits, an alarm indicator is latched on, giving the operator an indication of potential battery problems, and/or an indication of a battery/charger mismatch whereby one is over or under rated with respect to the other.

Abstract: 1                 PHF. 78-573.      ABSTRACT:        A method of and an apparatus for tomographic examination by X-ray or gamma ray scanning of structures, intended for the display of images of slices of the structure examined by determination of the electron den-sity in each volume element of these slices.  Using an X-ray or gamma ray source, a stationary principal detector and an auxiliary detector which is aligned with the source, for each volume element of each slice two measurements are performed of the diffusion by the Compton effect towards the principal detector and two measurements are performed of the transmission between the source and the auxiliary detector, starting with the slice nearest to the principal detector and proceeding to the slice which is situated furthest from this detector.  The measuring results are progressively used for calculating the exact electron density throughout the structure examined.

Abstract: ABSTRACT   An improved method for producing coating agents in powder form by the precipitation process is described.  The powdered coating agents have a polyamide base having at least 10 aliphatically combined carbon atoms per carbonamide group, or co-polyamides, or mixtures of homo- and co-polyamides, containing at least 70% of the said components.  The method is characterised in that polyamides having a relative viscosity of between 1.4 and 1.8 (measured in a 0.5% m-cresol solution at 25°C) are mixed with at least twice the amount by weight of ethanol, the said mixture being converted by mechanical movement, at temperature of between 130 and 150°C, into a solution, this solution being then adjusted to the precipitation temperature of between 100 and 125°C, with no local undercooling, the solution being then stirred, at low r.p.m., in an inert gas atmosphere in order to prevent boiling, without further addition of heat, in order to produce powders having a grain-size distribution of at least 95% between 40 and 250 µm, or being stirred at higher r.p.m., in order to produce powders having a grain-size distribution of 100% less than 100 µm, until particle-forming comes to an end, the suspension thus formed being finally cooled to at least 70°C and, if necessary, after partial mechanical removal of the ethanol, being then dried, initially at a reduced pressure, at wall-temperatures of 100°C at the most, with gentle mechanical motion and, as soon as it is capable of flowing, at wall-temperatures of up to 150°C and with more forceful mechanical motion.

Abstract: IMPROVEMENTS IN OVERHEAD HOIST ASSEMBLIES            ABSTRACT OF THE DISCLOSURE         When a hoist is used to elevate a grain truck for dumping same, at an elevator terminal or the like, a pair of lift cables extend from the overhead hoist assembly to the cradle upon which the front wheels of the truck are en-gaged.  As the truck is lowered after emptying the grain therefrom, the slack cables often foul the truck as it is being driven from the cradle.  In the present device, each cable passes through a spring loaded arm normally urging the cables outwardly away from the sides of the truck there-by clearing same, but which are aligned against the spring pressure as soon as the lifting load is applied so that the cables run vertically from the hoist assembly.

Abstract: ABSTRACT OF THE DISCLOSURE         An accumulatorless process is disclosed for bounce crimp texturizing thermoplastic yarn.  The process includes the step of supplying at least one drawn multi-filament thermoplastic yarn to a bounce crimp texturizer thereby texturizing the yarn.  The texturized yarn is collected by winding the yarn on a rotating winder spindle.  The relative tension on the texturized yarn is sensed at a position between the bounce crimp texturizer and the  winder spindle and the rate of the yarn wind-up is reduced when the sensed tension on the texturized yarn exceeds a predeter-mined tension value and the rate of the yarn wind-up is increased when the sensed tension on the yarn is equal to or less than the predetermined tension value.  The pre-determined tension value is selected at a value to ensure that the freshly texturized yarn is discharged from the texturizer in an essentially tensionless state without intermediate texturized yarn accumulation.

Abstract: ABSTRACT OF THE DISCLOSURE          According to the present specification a method for the recovery of ocean sediments is dis-closed as well as a device to be used in the recovery of sediments.   The method includes freely suspending a suction pipe which has a suction head at one end which is slowly lowered into the sediment.   Loosening means attached to the suction head is activated to dislodge the sediment and allow the removal thereof.          The loosening means is activated by the movement of the suction pipe.   The device for carrying out the method includes a floating body from which the suction pipe is flexibly suspended with the lower end of the suction pipe having a suction head and loosening means.          The loosening means are fixedly secured at the lower end of the pipe and the device further includes means to maintain the suction pipe in continuous motion.          This method mitigates vibration problems encountered in many prior art structures.

Abstract: 27-12833/AFR/+            Device for the metered release of an active ingredient Abstract A plug-type carrier (1) which is provided with an axial pipe nozzle (2) is inserted into the neck (4) of a stock container (5) for active ingredient, which is loc-ated with its neck downwards, for example  in a toilet cistern.    A float (3) is guided, so that it can move up and down, in the pipe nozzle by means of a guide rod (11). The float contains a metering chamber (9) and, at a lower level, a collecting chamber (7) which latter, together with an overflow pipe (8) and a beaker (10) surrounding the latter, forms a run-out syphon.    When the float is in its lower end position, the metering chamber (9) is filled with active ingredient.   When the float is raised, the chamber overflows and the active ingredient flows into the collecting chamber (7), where it is pre-diluted by the flushing water which simultaneously runs in from the outside.    When the float falls, the diluted active ingredient is syphoned out of the collecting chamber (7) into the flushing water and the metering chamber is filled anew.     The device is constructionally simple and makes it possible always to release constant quantities of active ingredient in a controlled manner into that part of the total flushing water in the cistern which remains in the syphon of the pan.
