. Journal. in Digesting Apparatus. W. H. Munus,London. From G. Kaffenberger, Cleveland, Pat. 6057, April 8, 1891. The object of the present invention is to produce a digestingapparatus, in which the process may be carried on in acontinuous manner. The invention comprises a conduit,which has a receiving and a discharge end. Twovalves are arranged near the discharge end forming achamber in the conduit between the valves. A similararrangement is provided at the receiving end. Suitablehorizontal cylinders, with piston and valves, open at one endinto each of the above-mentioned chambers.

The digesterthus consists of three chambers. For details of the modeof working, which here specially refers to the digestion ofstraw for paper - making, the specification should beconsulted.—E. S. A Neiv or Improved Filter Pump. F. C. Nordtmeyer,Breslau, Germany. Fng. Pat. 7155, Apiil 25, 1891. The patentee provides a filter in the shape of a pump,which he calls a filter pump, in which the piston or ram. is composed of filtering material through which the waterpasses in a filtered state as the ram is pressed home ;the unfiltered water enters the pump through a suction-valve. The accompanying cut shows one of the twomodifications illustrated in the drawings. a is the pump cylinder, b the suction-valve casing, withthe opening c, the ball-valve i, and the strainer d. To therainy*is secured, in a central position, the filtering materialA, through which the water passes reaching the spout andhandle It through the stem g. An outlet valve is stated tobe unnecessary, owing to the resistance offered to the waterby the filtering substance on the return stroke. This pump is intended to replace the ordinary portablepocket filter. It raises the water to a convenient height fordrinking and can be readily taken to pieces for cleaningpurposes.—B.
