Title: Filter system with coupled valves - allowing single mechanical action to change over
Inventor: RAMMO E R
IPC: B01D35/00
Filed: 1975-07-01
Abstract: Filter plant has provision for bankflushing and reslurrying the medium. The filter is a multi-layer sand or other particulate medium filter. It is equipped with 3 or 4 way valves or straight through valves. These are so coupled together that a sinel lever turns them through 90 degrees. The motion is linear and can be hand or mechanically induced. This changes the filter from filtering to bankflushing. Pref. a recirculation mode can also be introduced after the bankflushing mode. This requires an extra valve which is spring loaded. For recirculation valve is held by a latch which is released at the end of the recirculation phase of the cycle. This latch can be hand or mechanically operated. Arrangement is esp. for use with swimming bath filter installations. Allows straight forward commercially available valves and fixtures to be combined in a simple arrangement. The whole cycle change then involves a single stroke in either direction.

Title: Frequency modulated oscillator for radio links - has linear range increased by connecting RLC circuit in parallel with resonant circuit
Inventor: BARTH HERMANN DIPL ING
IPC: H03C3/22
Filed: 1976-02-27
Abstract: The frequency modulated oscillator, for radio link's broadhand FM modulator, has the linear part of its characteristics increased so that it is suitable for direct modulation in a broadhand radio link with eg 2700 voice channels. (The oscillator oscillates at the link's IF frequency). This is achieved by connecting a series RLC resonant circuit (Cs, Ls, Rs) in parallel with the oscillator LC resonant circuit (VD, Ck, Lk). The series resonant circuit shifts the fall-off in linearity near the upper frequency limit to a higher frequency. The linearity may also be extended down to lower frequencies by increasing the reactance of the oscillator's LC resonant circuit.

Title: Radiation dosimeter with reading by external detector - has automatic compensation of zero-dose reading by superimposed charge
Inventor: RONGE WERNER
IPC: G01T1/14
Filed: 1976-08-06
Abstract: The parent patent describes a dosimeter, in which an electrical field is generated by electrets in a closed, gas-filled chamber; the ionising radiation to be measured produces charge pairs in this chamber, and these are separated by the electrical field. A field detector outside the ionisation chamber measures the electrical charge. In this addition, the field produced, by the electret charge and/or by an undesired excess charge on the electrets or an insulation foil on them, at the location of the field detector is compensated by an additional charge applied onto the outer side of the electret nearest to the field detector or onto the outer side of the foil nearest the detector. The zero-dose signal is compensated, so that evaluation of the actual reading by a subtraction operation is obviated.
