Abstract: SWIMMING POOL COVER                     Abstract of the Invention A protective swimming pool covering apparatus is disclosed wherein the apparatus includes a flexible impervious cover sheet capable of being extended and retracted over a swimming pool.  Each lateral side of the cover sheet is adapt-ed with a longitudinally beaded side edge which is slideably held in a longitudinal open channel or track cut into a slide-way member fixed to the longitudinal margins of the swimming pool.  The longitudinal opening of the slideway means is sized such that it is slightly smaller than the diameter of the beaded side edge such that under normal operating conditions the bead will be slideably held within the track or channel. However, under conditions of excessive lateral stress, the bead will be sufficiently compressed and be pulled through the opening and away from the channel.  In addition, the end sections of the slideway means is adapted with a stationary channeled guide piece having a pair of flared end sections and a longitudinal side opening.  The stationary guide piece is mounted such that the channels of the guide piece and the slideway means are in aligned registry with each other.  The longitudinal side opening of the stationary guide piece is substantially smaller than the longitudinal side opening of the slideway means making disengagement of the bead from the channel opening substantially more difficult than that from the slideway means.

Abstract: ABSTRACT OF THE DISCLOSURE         A data handling system for use with a radiographic scanner for measuring the attenuation of radiation after passage through a medium in order to reconstruct an image representation.  A source of radiation is mounted to pass radiation through the medium along a set of paths.  At least one detector is located opposite of the source to measure the intensity of radiation traversing the medium along the paths. The set of data values corresponding to the intensity of radiation traversing a set of paths forms a data line.  The source of radiation is rotatably mounted to irradiate the medium from a succession of angular orientations which produces a succession of data lines.  A convolver convolves each data line with a filter function. The convolver comprises a data memory and a filter memory which have their output combined into a binary multiplier and transmitted to a product accumulator. The information is transmitted to a scale factor shift register and to a convolved data storage buffer.  Convolved data lines from the convolver are processed by an imager which utilizes holding registers, accumulators for the information and adders for transmitting the information to a memory where it is operated on in order to determine a projection address in an image matrix.  The projection address is subsequently operated on by a projection data-memory and multiplier in order to accumulate the representations of the different locations of the parts of the medium of interest.  A monitor displays an image representing a section of the medium as determined by the imager.          A system is also provided for setting a range of outputs of radiation of interest so that only certain scales or ranges of radiation are considered.  The convolver and imager process data lines as the detectors produce subsequent data lines.

Abstract: ABSTRACT OF THE DISCLOSURE        IMPROVEMENTS IN SPIRAL-WRAP APPARATUS     An improvement is disclosed in wrapping apparatus for palletized loads of the kind having a rotatable platform where the load is received, and a roll of plastic film mounted adjacent to the platform for vertical movement so that plastic film can be dispensed onto the load while the platform rotates, in order to enwrap the load helically. The improvement is the provision of an elongated roller member pivoted adjacent one of its ends to the platform so that it can swing between two positions through an arc in a vertical plane.  In the first position the member bears against a frictional surface on the platform, and in the second position it is spaced from the frictional surface. In swinging from the second to the first position at the end of a wrapping operation, the elongated roller member catches the film and pinches it between itself and the frictional surface.  A hot-wire severing means mounted adjacent to the frictional surface on the platform severs the film so that the first palletized load can be removed and a next load placed on the platform.

Abstract: ABSTRACT OF THE DISCLOSURE              The present process is an improvement of an earlier process wherein a nitrogen enriched gas is obtained from a gas containing oxygen and possibly other components. In that process the feed gas is passed in a continuous flow cycle through an ad-sorber containing carbonaceous molecular sieve coke followed by evacuation of the adsorber, oxygen and possibly other gas components being adsorbed and the discharged nitrogen-enriched gas being col-lected until the continually rising oxygen contents thereof reaches a predetermined limit value whereupon the molecular sieve coke is desorbed of the residual gases prior to the next charging cycle.  The present improvement is constituted by the feature that the flow of feed gas through the molecular sieve coke is effected at a con-tinually increasing pressure until a terminal pressure of about 3 to 10 bar has been reached.
