Abstract: 1,225,197. Geiger tube arrangements. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN. July 19, 1968, No.34521/68. Heading G1A. [Also in Division H4] Avalanche-type radiation detector tube pulses are coupled to utilization apparatus be detecting the electromagnetic radiation from the discharge in the tube, or the tube leads. The radiation is picked up by a special receiving antenna or by screws, brackets resistors inductor; transistors or wires which also have other mechanical or electrical functions. A simple or tuned transmitting antenna may be associated as a unit with the detector radiating pulses to a commercial radio receiver. The pulse produced by detection of the radiation may be used to test high frequency apparatus. When pulses in a multi-chamber tube are detected according to the invention the conventional plurality of load resistors may be replaced by a single load resistor so that a discharge in one chamber reduces the voltage on all chambers sufficiently to prevent parasitic discharges in the other chambers.

Abstract: 1,232,032. Settling sewage sludge. SOC. GENERALE D'EPURATION ET D'ASSAINISSEMENT. 26 July, 1968 [28 July, 1967], No. 35903/68. Heading B1D. [Also in Division E1] A sewage settling tank comprises a clear water overflow 18, means 22 for removing deposited sludge and, for removing the less dense fraction, and a pipe 34 having its inlet movable near the tank bottom and feeding a syphon 35-37. The syphon contains air, to allow the suction effect to be controlled. A bridge 28 rotates in the tank and carries scraper/eductor elements 29 (see Fig. 5). The scraper blades 30 are concave and carry flexible flaps 31 which push the densest sludge into sump 13 to be withdrawn whenever an automatic valve 23 is actuated. The eductor inlets 33 are at such a height as to suck away the lighter sludge. The suction rate is controlled by letting air into the syphons by means of a balanced valve arrangement controlled by a fluid pressure line (51) (see Division E1 and Figs. 3, 4 (not shown)), thereby partially "spoiling" the syphoning effect. The syphons discharge into a basin 19 having an outlet channel 20. Should a syphon become choked, all the other syphons are shut off, and the resulting fall in the level in basin 19 produces an increased pressure drop so as to clear the blockage.

Abstract: 1232116 Electro-depositing metallic filamentary networks CORNING GLASS WORKS May 28 1968 25391/68 Headings H1A A5 and A4D A metallic filamentary interconnected network is made by forming an electro-conductive coating on part of the external surface of a non-electroconductive porous body, e.g. of glass, ceramic or plastic, having intercommunicating pores of diameter not exceeding 200 angstrom units, preferably applying to the outer surface of the coating a non-electro-conductive coating e.g. of wax, and with the electro-conductive coating as the cathode electro-depositing a metal or alloy on the inner surface of the coating and causing metallic filament growth therefrom throughout at least part of the pores, using D.C. or an asymmetric A.C. potential. Part of the pores of the porous body may be filled with an inert non-electro-conductive material e.g. paraffin wax (in CCl 4 ) to prevent deposition of metal therein. The non-electro-conductive coating e.g. of wax may extend over parts of the surface of the porous body thereby sealing the pores therein, e.g. to produce electric circuit patterns within porous glass. At least part of the porous body may be then removed by etching, e.g. with NaOH for 96% silica porous glass prepared by acid leaching a phase-separated boro-silicate glass or with hydrocarbon solvent for porous plastic, to provide a network 16 which extends outwardly from at least one surface of the porous body 4. The filaments  deposited may be of Ni, Cr, Zn, Cu, Sn, Pb, Fe, Au, Ag, Pt, Pd, Rh, Al, Cd, Co, In, Hg, V, Tl, Ga, Ge or alloys thereof, e.g. brass, bronze, Co-Ni, Ag-Cd, Fe-Ni, Ag-Zn, Ag-Pb, Pb-Cu, Cu-Sn, Sn-Ni, Cu-Ag, Cu-Ni, Cu-Zn, Sn-Zn or Sn Cd. For example, porous glass, partially sealed with paraffin wax and with an indium film electrode thereon, was immersed, after treating in air saturated with water vapour to avoid cracking in an aqueous plating solution comprising 150g/lg/l Pb (OH) 2Pb CO 3 , 240g/l HF (50%) and 150 g/l H 3 BO 3 , using a Pb anode, to deposit dendrites of Pb within the pores of the glass for a superconductor. For Fe, Sn or Ag electrode-position in porous glass, aqueous plating solutions containing (a) FeCl 2  and CaCl 2 , (b) SnCl 4  and (c) AgNO 3  may be used. Other uses for the filamentary networks, may be glass-to-metal seals, resistors of metal catalysts.

It is statedthat possibly metallic chromium is deposited. The electrolysis electrolyte may be (i) an aqueous solution of chromic and sulphuric acid, (ii) a solution of chromic acid containing additions of silico-fluoride or fluoride ions either singly or  in combination with sulphate ions or (iii) a solution of a trivalent Cr salt dissolved in dimethyl formamide solution. The Cr-containing alloy may be austenitic, ferritic or martensitic stainless steel, iron based alloy of Fe-Ni-Cr-Mo-Ti-Al, cobalt based alloy of Co-Cr-Ni-Mo or an alloy of Ni-Cr-Ti. Different colours may be produced on different parts of the Cr-containing alloy by forming an acid-resisting layer on one or more areas, initiating the film-forming treatment, removing the acid-resisting layer, completing the film forming treatment, and then subjecting the whole alloy to the cathodic hardening treatment. Coloured steel sheets treated by the process can be deep drawn or passed through patterned rolls to increase their rigidity. Since the hardened coloured films resist boiling water, coloured stainless steel saucepans can be produced.
