Title: Forming uniform flexible film - on outer surface of tubular -formed fabric jacket
Inventor: TAJI KATSUHIKO
IPC: B05D1/18
Filed: 1973-08-03
Abstract: Method comprises dipping a continuous length of tube-shaped fabric jacket in the flattened form into a succession of latex baths, drying the latex coated jacket after it has dipped into the baths, and removing a portion of the latex coating covering the central flat portions of the flattened jacket by squeeze rolls immediately after the jacket has been lifted from some of the baths, to provide a uniform latex coating on the flattened tube after dipping and passing through all of the baths and dryer. In prior art techniques using no squeeze rolls, a greater thickness of coating is produced in the central flat portions of the jacket which results in lengthwise extending depressions on the coating when the tubular jacket is inflated. Method is used in the prodn. of water-impervious hoses, as e.g. used for fire fighting, the mfg. process including turning out the inside of the externally lined hose.

Title: Sector shaped filter elleent with herringbone groove pattern - promoting clean blowback using air without entraining filtrate
Inventor: OTTE WILHELM
IPC: B01D29/41
Filed: 1974-02-15
Abstract: A disc filter is constituted of a number of sector-shaped filter elements, having grooved surfaces to carry the filter cloths and an internal filtrate removal duct. These grooves in each sector, diverge as two sets of parallel grooves from a central spine, thus giving a V-pattern of "herringbone" pattern of grooves on each sector. Pref., each groove has a discharge hole near the spine, leading into the internal duct. The size of the holes is chosen to suit the flow from the groove. Each hole has, inside the element, a droplet-catching rim as a liquid rejector. The entire element is pref. of water-rejecting plastics, esp. polypropylene. With the herringbone pattern of grooves, blowing back of the filter, using air, does not tend to entrain large quantities of filtrate, which would make the filter cake excessively wet. Instead, the air skims over the grooves. Also the grooves are short.
