Abstract: 1484702 Wells &c FERDINAND AUFSCHLAGER KG 26 Nov 1974 [28 Nov 1973] 48395/74 Heading E1F A filter well for water comprises a plurality of vertical boreholes overlapping along the whole of their lengths and containing gravel. The boreholes may be formed along straight (Figs. 1 and 3 not shown), curved or closed lines, as viewed from above.

Title: Method of forming a metal amide monomeric complex and metal amide polymeric complex and products so produced
IPC: C01G1/00
Filed: 1975-11-25
Abstract: 1532416 Metal amide complexes G G MERKL 25 Nov 1975 [26 Nov 1974 17 Nov 1975] 48462/75 Heading C1A ' A metal amide monomeric complex is made by reacting in an aqueous medium, at least one non- alkaline metal selected from Groups I-VIII of the Periodic Table; an alkali metal hydroxide, and a source of reactive NH 2  groups the alkali metal hydroxide being added incrementally to the reaction medium at a rate and in a manner controlled so as to maintain a high concentration of dissolved alkali metal ions within a localized area in the immediate vicinity of the non-alkaline metal whereby the non-alkaline metal erodes to produce non-alkaline metal ions in the reaction medium which enter into an overall endothermic reaction with the alkali metal ions and reactive NH 2  groups to form a metal amide monomeric complex in which NH 2  groups are bound. The reaction may be carried out according to the following sequence: (i) introducing the non-alkaline metal into a reaction vessel containing the aqueous medium; (ii) providing in the aqueous medium, a supply of said source of NH 2  groups; (iii) adding the alkali metal hydroxide to the reaction vessel. The alkali metal hydroxide may be added in an amount and at a rate proportional to the rate of erosion of the non- alkaline metal. Aqueous ammonia, supplemented by ammonia gas, may be used as the source of NH 2  groups. The reaction medium may be cooled during the addition of the alkali metal hydroxide to assist in the development of the endothermic reaction, which may be initiated by the addition to the reaction medium of a small proportion of a different non-alkaline metal of Groups I-VIII, more reactive than the first non-alkaline metal. Localized areas of high concentration of alkali metal ions may be produced by adding the alkali metal hydroxide to the reaction medium in pellet form. The reaction may be terminated before an exothermic reaction becomes established, by removing unreacted non-alkaline metal from the reaction medium, to give a product thought to be of formula where M is the alkali metal, M" is the non-alkaline metal and y is the sum of the valencies of M' and M", or alternatively an exothermic reaction may be established in the reaction vessel characterized by increased erosion of the non-alkaline metal and the formation of a metal amide polymeric complex; the reaction may be initiated by heating after completion of the endothermic reaction and may be terminated as above. By a non-alkaline metal is meant any metal other than an alkali metal or an alkaline earth, but including also silicon, selenium and tellurium. Sodium and potassium hydroxides are the preferred alkali metal hydroxides. Examples illustrate the use, as non-alkaline metal, of silicon, zinc, tantalum, tin, beryllium, zirconium, niobium, molybdenum, aluminium, iron, bismuth, indium, titanium, cobalt, chromium, tungsten, manganese, nickel, silver, cadmium, gallium, antimony, tellurium, copper, magnesium, gold, titanium, and tantalum.

Abstract: 957,719. Pulse radar. SOC. NOUVELLE D'ELECTRONIQUE ET DE LA RADIO INDUSTRIE. June 9, 1960 [June 26, 1959; April 7, 1960], No. 48494/63. Divided out of 957,718. Heading H4D. Relates to means for discriminating against the effects of random noise in a pulse radar in which an echo pulse is produced by a target in each of a plurality of successive radar pulse recurrence periods, the timing of each echo pulse being quantized with references to clock pulses, Fig. 1c, synchronized with and of higher recurrence frequency than the transmitted pulses and the successive quantized signals being correlated to produce a single output pulse representing the target; in such a system a time quantum is defined as the time interval between two successive clock pulses. According to the present invention the recurrence period of the clock pulses is less than the duration of the transmitted pulses, a narrow pulse L1, Fig. 1b of predetermined amplitude is generated when the instantaneous amplitude of an input signal, Fig. 1a, exceeds a threshold level, a further narrow pulse L3 is then derived coincident with the clock pulse L2 immediately following the pulse L1 and the pulse L3 successively initiates pulses L4 and L5 having durations respectively equal to (1) one time quantum, and (2) the duration of the transmitted radar pulse, e.g. six time quanta. Due to fluctuations in the signal/noise ratio, the timing of the pulses L5 and L5 produced during successive radar recurrence periods may vary as shown in Figs. 2 and 3 respectively and a single output range pulse S, Fig. 3g, is derived corresponding to the common coincident portions of the pulses L<SP>1</SP>41-L<SP>1</SP>45. The pulses L1 are produced by a trigger circuit 5, Figs. 4 and 5 (not shown), whose threshold triggering level is controlled as described in Specification 957,718 with reference to the corresponding Figs. 2 and 3 therein. The pulse L1 and the clock pulses are applied respectively to the two inputs of a bistable trigger circuit 18, Fig. 6, to give the output pulses L3 and each pulse L3 is then converted in a first shaper 19 into a pulse L4 which is applied through a memory circuit 20 to a second shaper 21 to give the output pulse L5. Output signals coded in accordance with the amplitude of the input echo signals may be produced by providing a plurality of trigger circuits 5 having different triggering thresholds.
