Abstract: A washable floor for a urinal consists of a metal grid (10) through which fluid may pass downwardly and an inclined sub-floor (6) on which the fluid falls. A flushing system flushes the inclined sub-floor (6) towards the urinal. This greatly reduces odors.

Abstract: Count-key-data records are mapped to a fixed-block architecture storage device using a fuzzing packing method that packs some count-key-data records while writing other count-key-data records at a beginning of a next available sector (unpacked) according to the size of the count-key-data record, the size of the sector, and the location of the next available byte for writing data in the current sector. If the number of sectors required to write the current record starting at the next available byte location in the current sector, is greater than a minimum number of sectors to write that same record if that record were written at the beginning of the next available sector, then the record is written unpacked, otherwise the record is packed.

Abstract: A method and apparatus for updating CKD data stored on fixed block media, and more particularly to creating Track Format Descriptors which are data structures loaded into electronic memory to enable fast writing of data without loading an entire CKD emulated track of data into memory. A control unit is provided with logic to provide Track Format Descriptors which describe the format of the track without the need for the data content of the track to be resident in cache, or electronic memory. An emulated CKD volume corresponds to a volume of data stored on a multi-disk device. Each track on a volume is represented by a Track Format Descriptor. The Track Format Descriptor forms a representation of the format according to the following general procedure. If the format is a predefined format, in other words one that is already known by the control unit then a track form descriptor is formed to represent the format. If the format is easily discernible, it is said to be "well behaved".
