Patent IT-1161558-B (IT)
Title: HF electronic ballast device for gas discharge lamps
Inventor: VOSSOUGH ESHAN
IPC: H01J/
Filed: 1983-01-27
Granted: 1987-03-18
Abstract: The oscillator which supplies the two complementary square wave outputs, receives frequency-controlling input signals on any of the control inputs. The outputs are applied to a driver circuit for controlling the operation of an inverter. The inverter output is a source signal for a transformer or choke arranged to drive directly the gas discharge lamp. A DC power supply outputs a high level supply voltage to the inverter and a LV to the oscillator and driver. A feedback control loop regulates the inverter current by varying the oscillator frequency to maintain a constant light output from the lamp for fluctuating mains voltage. The input controls of the oscillator provide for dimming the lamps.An increased frequency of operation is achieved which leads to efficiency being raised by about ten per cent. This allows reduced power input for a given light output, thus saving energy and enhancing lamp life.

Granted: 1985-02-11
Abstract: Aromatic polyethers comprising phenylene gps., O atoms and -CO- or -SO2- gps. are prepd. by reacting at least one dialkali metal salt of a bisphenol fo formula (I) (a) or (b) with at least one dihalide of formula (II): where at least 95% of the -OH gps. in (I) are in the p- position, Q = SO2 or CO, X = F, Cl or Br, m and m' = 0, 1, 2, or 3 and n and n' = 1, 2, or 3. The mixt. is first heated to 200 degrees -250 degrees C in the presence of an aromatic sulphone of formula (III): (where Y represents a direct linkage, an O atom or 2 H atoms, one attached to each ring, Z and Z' are H or Ph and can be the same or different, the mixt. is heated to 260 degrees -400 degrees C and the proportions are initially 30-49.99 mol. % of the dialkali metal salt of (I) to 70-50.01 mol. % of (II), while after raising the temp. as indicated at least 0.01 mol. of (I) per 100 mols. mixt. is added to bring the (I):(II) ratio to 50:50. The process, previously described in GB 1,414,421, furnishes particularly good polymers, if an excess of dihalide is used as in the invention and more bisphenate is added later, giving a prod. of higher reduced viscosity.

Title: Separator for washings from concrete mixers and transporters - which separately recovers gravel, sand, cement and clean water
IPC: B28B17/00
Filed: 1973-12-03
Granted: 1981-03-10
Abstract: A separator for washings from concrete mixers and delivery trucks includes two tanks. The first is an open-topped horizontal semi-cylindrical structure with a rotating shaft along its centreline to which are attached three drums and two spiral scrapers. The first drum filters out gravel and stones, the second sand, whilst the third transfers the water/cement residue to the second tank. The scrapers move the sand towards the second drum. The second tank has a flat bottom, vertical sides and flat, outward sloping ends. The cement settles to the bottom which is continuously scraped to remove the sediment. The clean water is precycled to the washing out station. The design permits the rugged construction appropriate to the machine's use. Materials are recovered. Water is conserved. Hard deposits of concrete are avoided in the washing station.

Abstract: A method and apparatus for diversity reception in a communication system is provided. A dual branch receiver (100, 101) is provided with a stored replica of expected reference information (104) so that correlation with received time-dispersed signals produces an estimate of the transmission channel's impulse response as seen by each branch (100, 101), and determines, among other things, phase error between the branch local oscillators (208, 209) and the time-­dispersed signals. Matched filters (214, 215) are constructed which then coherently align the time-dispersed signals from each branch (100, 101) with that branch's local oscillator (208, 209) which constitutes a part of the signal equalization. A diversity processor (105) performs bit by bit selection on the re-aligned signals, maximal ratio combining of the re-­aligned signals, or equal gain combining of the re-aligned signals, followed by a sequence estimation which uses similarly selected or combined channel distortion compensation parameters to complete the equalization process on the new signal.
