Abstract: 1,245,453. Papermaking machines. BELOIT CORP. 8 Oct., 1968 [6 Dec., 1967], No. 47703/ 68. Heading D2A. Apparatus for forming multi-ply paper comprises, in successively spaced arrangement, paper-forming segments, each segment comprising a first guide roll e.g. 86 in segment S8, a second guide roll 81f, and a stationary guide 83, felt 200 wrapping the first guide roll, and wire 84 wrapping the second guide roll and the stationary guide 83, which stationary guide presents an elongated, stationary, unyielding water-permeable surface, which urges the wire and felt into gradual convergence from initially close spacing, and effects water removal; and a fourth guide roll 89 effective to separate the wire run from the felt which carries the web. A number of these segments are spaced along the felt bottom run. The second guide may be a suction box, and is preferably constructed with a plurality of longitudinally closely spaced, transversely extending blades presenting top thin edges to the wire to define the water-permeable surface. The longitudinal shape of the locus of these (blade, edges may define an elongated, non-circular convex curve. The compound web, at the off-running end of a ply-forming segment may pass through a pair of press rolls which may act on the felt carrying the web, or may act on the feltweb-wire sandwich, as shown. In this. latter case, it is preferred to use a plastics forming wire.

Title: Tank pump
IPC: F04D29/22
Filed: 1975-11-20
Abstract: The pump has a riser (1) with a drive shaft (5), which carries a rotor (16) which with one part (18) is situated at an axial distance (X) opposite a wall section (23) of a pump casing (8). The drive shaft (1) is made of metal, while the riser (1), the pump casing (8) and the shell tube (5') are made of plastic. The axial distance (X) is chosen to be sufficiently large for the rotor, at the temperatures occurring during operation, not to chafe on the casing. To minimise the return flow of the liquid to the suction side at all operating temperatures, the rotor (16) has a cylindrical section (17) which has a zone which is surrounded by an inner wall part (11) of the pump casing (8) with radial play and has an axial extent (Y) which is at least equal to the axial distance (X). Moreover, the axial distance (X) does not have to be reset in each case at different operating temperatures. <IMAGE>

Chlorine is produced by electrolysis of an aqueous chloride solution at a pressure not exceeding about 200 mm. Hg. Typically sodium or potassium chloride solution is continuously introduced into the cell and chlorine is continuously removed. Chlorine so removed or an aqueous solution of active chlorine (hypochlorite) produced by such electrolysis is added to water to be chlorinated at a rate depending on a determined property of water which has been previously chlorinated, the amount of chlorine or active chlorine solution being controlled by varying the electrolysis current. Typically in this case the electrolysis is carried out at a pressure of 1 to 10 mm. Hg. obtained by use of a jet pump employing as the jet a stream of the water to be chlorinated, the pump also removing electrolysis products from the cell. The electrolysis cell may be a tubular cathode surrounding an anode or may be of a rectangular vertical stack construction held together by I-bolts, the stack consisting in order upwardly of a plastic plate, an apertured packing piece, a graphite anode, a further apertured packing piece, a plastic frame, another apertured packing piece and a further plastic plate, the cathode of perforated iron (or an iron-containing compound) being disposed close to the anode in a holder depending from the second plastic plate.

Abstract: 1,245,708. Capacitive amplifiers. CESKOSLOVENSKA AKADEMIE VED. 8 Oct., 1969 [9 Oct., 1968], No. 49374/69. Heading H3B. [Also in Division H2] Relatively low D.C. voltages Em (e.g. from measuring circuits) are converted into A.C. voltages E 2K  by an inverter comprising a ferroelectric disc 10 (Fig. 1), e.g. a single crystal of triglycinesulphate, in thermally autostable mode of operation and which forms a mechanical resonator when excited piezo-electrically by an A.C. voltage E 1  from a generator 2 applied between an annular excitation electrode 12 and an electrode 11. A pick-up region 103 is maintained by heat transfer from the exciting region 102 which is heated by the dielectric losses, at the temperature of the phase transition of the ferroelectric disc (Curie temp.), and is contacted by a pick-up electrode 13 and the electrode 11. In this thermal region the piezoelectric coefficient d of the pick-up region 103 depends upon the D.C. voltage Em applied between electrodes 11 and 13. With constant excitation voltage E 1  therefore, the pick-up piezo-electric output A.C. voltage E 2K  magnitude is directly proportional to the magnitude of voltage Em and has a frequency equal to the 2nd harmonic of the excitation frequency. The "working point" of the disc 10 is set by an adjustable D.C. bias from a source 7. The inverter output E 2 K is amplified by an amplifier 4. The excitation frequency is adjusted to correspond to a critical frequency # 0  whereat shifts of the resonance peaks of mechanical vibration and hence of the output voltage E 2 K, in dependence upon temperature, are minimum (Fig. 2, not shown).
