Title: Improvements in or relating to time division multiplexing telephone exchanges
IPC: H04Q11/04
Filed: 1969-10-27
Abstract: 1280220 Telephone exchanges SOC ITALIANA TELECOMMUNICAZIONI SIEMENS SpA 27 Oct 1969 [17 Dec 1968] 52405/69 Heading H4K In a TDM exchange employing a recirculating memory for subscribers' addresses, which memory feeds a decoding matrix producing for each address an output on one only of a group of output lines, a monitoring circuit is adapted to respond to more than one output on the group of lines. In the arrangement shown the decoder H has only one group of output lines H 1  to H n  and normally provides an output on one line for each subscriber address decoded. A set of diodes D1 connect each line to a common line Y 1  connected to a potential divider comprising resistors R 1 <SP>1</SP> and R 1 <SP>11</SP>. The divided potential forms one input of a differential amplifier Al which produces an output switching a transistor T 1  if this input exceeds a reference potential supplied via a divider R 2 <SP>1</SP>, R 2 <SP>11</SP>. The reference potential is set such that the transistor T 1  is switched when any line H 1  to H n  is energized by the decoder. A second set of diodes D each in series with a resistor R connect the lines H 1  to H n  to a common line Y 2 . An amplifier A2 and a transistor T 2  are connected in a manner similar to that for Al and T 1  to respond when two or more of the lines H 1  to H n  are energized simultaneously by decoder H. Thus an output V 1  is produced each time an address is dedoded and in the event of erroneous marking of two lines an additional output V 2  is also produced.

Offgas obtained in the synthesis of melamine by reaction of urea at elevated temperature in the presence of added ammonia and a catalyst is processed by separation of the melamine by cooling the offgas to 150-250 C. by mixing it with colder gas, wherein separation of melamine with or without urea from the offgas is carried out by direct cooling with ammonia, and the offgas is then further cooled to temperatures of - 35 to + 60 C. by mixing with more ammonia and the ammonium carbamate thus obtained is separated from the gas which then consists of practically pure ammonia. The cooling ammonia employed preferably has a temperature of from - 30 to + 30 C.; after separation of melamine from the offgas, the offgas may be cooled, by mixing with more ammonia, to a temperature of 100 to 150 C. to separate urea. The ammonia which is separated may be returned to the melamine synthesis.

Abstract: 1490229 Coated products WESTERN ELECTRIC CO INC 9 Dec 1974 [12 Dec 1973] 53086/74 Heading B2E [Also in Division G2] At least part of the surface of a substrate is rendered hydrophobic by coating the surface with an aqueous colloidal wetting solution comprising particles of an insoluble hydrous oxide of one or more of Be, In, Cr, Fe, Co, Ni, Tl, Cu, Zn or Sn. the particles having a size of 10-10,000 Š and the solution having been formed by a hydrolysis and nucleation reaction including at least dissolution of a salt of the selected element in an aqueous medium and maintenance of the pH of the aqueous medium at a point where no flocculate results, and subsequently exposing at least a portion of the coated surface to UV radiation to render the exposed portions hydrophobic. The substrate may comprise plastics film (PTFE. polyethyleneterephthalate, polyimide, epoxy resin), glass plate, a glazed or enameled article, porcelain, asbestos, quartz, mica, cement, or metal and the wetting solution may be applied by dipping, spraying or brushing. After exposure of the surface coated with the colloidal solution (which may itself render the surface hydrophilic) to UV through a mesh to provide hydrophobic portions, a water-based ink such as polyvinylalcohol solution Œ TiO 2  or ZrO 2 , an alkyd-based ink or a gelatin ink may be applied by rolling to coat the unexposed areas and form an ink pattern for subsequent printing. Alternatively, a conductive ink containing graphite, powdered Ag, Pt, Pd, An or Cu, silver oxide, silver nitrate or a noble metal resinate together with a binder (such as L phenolic resin) and solvent may be applied and the ink pattern subjected to an electroplating or electroless plating treatment to provide a copper deposit. When electroless plating is to be effected, the exposed coated surface is sensitised by deposition thereon of Sn<SP>2+</SP>, Ti<SP>3+</SP> or Pb<SP>2+</SP> ions, rinsed in water, and activated by deposition of a catalytic metal such as Pd over the unexposed areas, which areas subsequently become plated in the plating bath.

Abstract: 1436363 Keyboards and displays HITACHI Ltd 15 Nov 1973 [27 Nov 1972] 53132/73 Heading G4H In a display system, a timing pulse train Dt 1 -Dt n  is used to select digits of the display DP and to time-division-multiplex key signals from a keyboard KB, depression of a plurality of the keys K 1 -K n  being detected DT with prevention of multiple illumination of the display DP. The timing pulses Dt 1 -Dt n  occur consecutively on respective leads, so that actuated keys K 1 -K n  apply time-significant pulses to detector DT and an arithmetic unit AM. The output of the arithmetic unit AM, unless blocked at AND gate AG 1  by detector DT in the event of plural key actuation, is decoded at DC to actuate display DP, display positions of which are selected in turn by the timing pulses Dt 1 -Dt n . If the blocking feature were not present, and say keys K 1  and K 3  were actuated together, pluse Dt 1  would be applied to the lead for Dt 3  as well, via K 1  and K 3 -hence multiple illumination. In the case of plural key actuation, the first pulse from the keyboard sets a flip-flop in detector DT to enable a gate to pass the second pulse to set a second flip-flop to disable gate AG 1  via an inverter. The first flip-flop is reset by a word pulse, and the second flip-flop is reset by a clear signal, e.g. on key release. In Fig. 1, IC is a single semi-conductor integrated circuit. DC may be included in it.

Title: Method and apparatus for the purification of liquid
IPC: B01J47/10
Filed: 1977-12-28
Abstract: The apparatus has a liquid treatment column (10) in which an at least extensive purification of a liquid takes place. This purification step is accomplished by passing this liquid upwards through a bed of purification material (M) present in the liquid treatment column (10). There is also a regeneration column (50) for regenerating the purification material. The liquid treatment column (10) has a feed opening and a transfer opening in the upper and lower part and contains a bed of purification material (M) which is located at a predetermined distance below the upper end of the liquid treatment column, so that a reservoir space results. In addition, the treatment column has a liquid inlet and a liquid outlet, the part of the purification bed above the liquid outlet serving as a settling layer in order to avoid any fluidisation and/or expansion of the purification material. The regeneration column (50) is of a design similar to that of the treatment column (10), but compressed air and washing liquid are introduced either successively or simultaneously into the regeneration column for fluidising the contaminated purification material, i.e. for separating off the suspended solids from the purification material particles. The regenerated purification material is fed continuously or intermittently to the purification column. <IMAGE>
