[Also in Division D2] A method of wet pressing a moist web of absorbent material, e.g. paper, between cooperating press rolls comprises passing the web between the press rolls together with a felt and a separate open structure water-receiving mat, and directing the dewatered web away from the felt immediately after leaving the nip, with the felt and the mat immediately leaving the rolls after the nip and remaining in intimate contact with one another for a short distance so that a substantial quantity of the water received and held by the mat is re-absorbed by the felt after which the felt is freed from absorbed water for example by suction or pressing. The mat may comprise a plastic fabric, and the web may be returned to the felt after the felt has been dewatered.

Abstract: 988,758. Sorting letters &c. STANDARD TELEPHONES & CABLES Ltd. Nov. 8, 1963 [Nov. 12, 1962], No. 44166/63. Heading B8A. [Also in Division G4] A mechanical data storage device which may be used for sorting letters includes pairs of rotatable magnets, one magnet of each pair being set to store data while the other is used to retain the set magnet in position. As described an operator selects 1 of 1000 possible destinations and enters three decimal digits using a keyboard having three sets of ten keys. The keys set switches 7, 8 of three sets of five electromagnets 5 so that the directions of magnetization of the cores 4 represent the digits in 2 out of 5 code. A rotary drum 20 carries uniformly spaced sets of wires 22, 23. Each wire 22 has three sets of five magnets which are rotated under the influence of the electromagnets 5 to indicate the three digits, and each wire 23 has three sets of five similar magnets each of which acts with its corresponding one on the wire 22 as a bi-stable pair. The drum rotates and the information is passed to further less powerful bi-stable pairs of rotary magnets 27, 28 on a carrier such as 26 on a chain conveyer. At a reading station, control relays 31 for each of 1000 destinations have six serially connected reed switches 13 connected to each relay, the six switches being positioned adjacent points at which the six magnets 27 set to the " one " state would pass if the digits stored in the carrier 26 indicate that particular destination. If this occurs all the six reed switches are closed by the influence of the magnets, and thus that particular one of the relays 31 is energized to control transfer of the letter or article to the particular output destination.

Abstract: 1,241,434. Heart valves. MINNESOTA UNIVERSITY, REGENTS OF. 19 Sept., 1968, No. 44677/68. Heading A5R. [Also in Division F2] An artificial heart valve 10 comprises an annular base 12 having a seat 16 for cooperation with an annular valve member 17, an obturator member 19 secured centrally of the base 12 for co-operation with a central opening in the valve member 17 and a cage 28 for limiting the movement of the valve member 17. The valve member can be a toroid, an annulus having a generally rectangular cross-section (33, Figure 4), a tubular annulus having a circular cross-sectional shape (34, Figure 5), an annulus having a kidney shaped cross-section (36, Figure 6), frustum of a hollow cone (78, Figure 13, 62, Figure 11) or a part of a hollow sphere (96, Figure 14). The obturator member 19 may be positioned above or below the base along the longitudinal axis of the valve. The obturator member 19 may be supported by a plurality of legs 24 each secured to the obturator member at one end and the base 12 at the other, or by a rod (38, Figure 7) secured between a top portion of the obturator member (19A, Figure 7) and the cage (28A, Figure 7). The cage consists of a plurality of circumferentially spaced legs 29, secured to the base 12. The legs 29 act as guides for the valve member 17 and have their ends radially inwardly directed and connected to a common apex point 32. When the valve member is in the form of a frustum of a hollow cone or part of a hollow sphere movement of the valve member is limited by a rod (87, Figure 13, 104, Figure 14), which is secured to the top of the obturator member (82, Figure 13, 99, Figure 14) and has three outwardly inclined fingers (89, Figure 13, 107, Figure 14) provided at its upper end. Alternatively movement of a hollow frustro conical valve member may be limited by three rods (71, Figure 11), each projecting upwardly from the top of the base (57, Figure 11) and each having an inwardly inclined upper section (72). In the closed position the valve member either makes contact with the valve seat and obturator member or is slightly spaced from these components relying on viscosity of the blood to prevent flow through the valve.
