Title: Improvements in or relating to Filters.
IPC: B01D29/00
Filed: 1918-02-12
Abstract: 123,152. Pulsometer Engineering Co., and Bj÷rnstad, J. Feh. 12, 1918. Filters with loose filtering- materials.-Water and air for cleansing a filter bed are admitted to the bed by two sets of nozzles at different levels, the inlet to the air-nozzles being at a higher level than that to the water nozzles, so that the air and water do not interfere with each other. The water-nozzles 4 are arranged at the bottoms of pockets 2 in the bottom plate of the filter, and the air nozzles 5 in the spaces between the pockets. The air enters through a central pipe 9 and passes between the pockets 2 to the nozzles 5, finally escaping through a valve 15. The water enters from the filtered-water main by the pipe 8, and after passing through the nozzles 4 and the filter bed, escapes by an overflow-box 11 and pipe 13, which also serve to supply water to be filtered. The pressures of the air and water are so adjusted that the air can depress the water below the level of the nozzles 5 but cannot reach the nozzles 4. To prevent an excessive pressure of water a lift valve, the motion of which is regulated by an adjustable stop, is placed in the pipe 8, so that water leaving the filter passes freely, but flow in the opposite direction is obstructed, but not prevented.

[Class 40 (v)] In a piezo-electric crystal discriminator circuit employing a condenser for neutralizing the capacity of the crystal holder, further condensers are provided connected respectively in shunt to the crystal and to the neutralizing condenser to afford under-neutralization and over-neutralization characteristics at the inputs to a pair of opposed rectifiers. Fig. 1 shows a phase-modulation receiver in which IF carrier is fed to a pentode valve 1 having a tuned anode circuit coupled to a centre-tapped coil 7, one end of which is connected to the crystal P and the other to a neutralizing condenser 13. The other terminals of the crystal P and condenser 13 are connected to each other and through isolating condensers 9, 9<1> to the anodes of rectifiers A, B. The ends of the coil 7 are also connected to the rectifier anodes through an under-neutralization condenser 21 and an overneutralization condenser 22. The rectifiers are shunted by resistances 19, 20 and are in series with resistances 14, 15 the respective junctions being connected to the centre tap of the coil 7. One rectifier cathode B is earthed, and the voltage taken from the other cathode contains both the detected PM signal, and a slowlyvarying component for use in tuning the local oscillator. The anode of rectifier A supplies a voltage representing any amplitude modulation of the carrier. The centre-tapped coil 7 may be connected as a tuned coil in the anode circuit of the valve 1 (Fig. 4, not shown). In Fig. 5, the tuned anode coil 4 is connected to one end of the centre-tapped coil 30 by the crystal P, and to the other end by the neutralizing condenser 13. The isolating condensers 9, 9<1> and the under- and over-neutralizing condensers 21, 22 are connected similarly to Fig. 1. The centre-tapped coil 30 is tuned by the condenser 31 to one side or the other of the carrier frequency. U.S.A. Specification 2,204,575 is referred to.

Filed: 1963-01-25
Abstract: 1,004,035. Coaxial cables. L. ROHDE and H. SCHWARZ, [trading as ROHDE & SCHWARZ]. Jan. 25, 1963 [Feb. 27, 1962], No. 3186/63. Heading H1A. In a coaxial cable system in which the inner conductor is supported by arms 3 of dielectric material integral with a ring portion 2, the shape of the support is such that the fields between the conductors are either parallel or perpendicular to its boundaries and this is achieved by making the edges of the arms 3 radial and by having the ring surface concentric with the inner conductor. The capacitative influence of the support is compensated by making a ring- shaped recess 7 in the arms 3. To match the impedance of the supported region of the system with that of the adjacent unsupported region the diameter of the inner conductor is reduced so that the ring 2 may engage a recess and the outer diameter d 3  may be increased. Alternatively, the inner conductor may be held by pairs of supports each of which has four arms each support being staggered relative to its neighbour to prevent air and/or dirt circulation.
