Abstract: 1517190 Ultrasonic detection of objects HITACHI Ltd 18 Sept 1975 [20 Sept 1974] 38414/75 Heading G1G The number of objects within a predetermined space, e.g. persons in an elevator hall, is determined by converting reflected ultrasonic wave signals to a first pulsating signal including pulses representative of each object, comparing, in wave shaping means, the pulsating signal and a reference signal to provide a second pulsating signal including all those pulses in the first signal having peak values higher than the reference signal to the exclusion of the other pulses, and providing from the second pulsating signal an output signal proportional to the number of objects. Figs. 3 and 4, show a pulse-echo embodiment in which the first pulsating signal ER is added to a gating signal EGAT and compared at CP1 with a reference EX1, the resultant second pulsating signal ECP being integrated at A2 to provide the output signal ED. In other embodiments, the signal ER is multiplied with a ramp gating signal in a variable gain amplifier, Figs. 7 and 8 (not shown), the signal ER is compared with a reference whose amplitude decreases in a predetermined manner, Figs. 10 and 11 (not shown), or the signal ER is compared with a reference and the resultant pulsating signal is amplitude limited by a signal having a predetermined slope and duration; Figs. 12 and 13 (not shown).

Title: A process for the preparation of polyamides
IPC: C08G69/08
Filed: 1965-09-09
Abstract: Homo- or copolyamides of e -cyclohexyl-e -caprolactam may be produced from the lactam or the corresponding aminocarboxylic acid.  The monomer may be polymerized by heating it in the presence of water or by anionic polymerization using an alkaline catalyst, e.g. NaOH, and a cocatalyst, e.g. an acetyl lactam. Copolyamides may be prepared using caprolactam, capryllactam, dodecanolactam as comonomers. The product may contain low M.W. constituents, e.g. monomer, which may be extracted with MeOH and recovered by removal of solvent from the extract or by pouring it in aq. NaCl solution.  The polymer may be used to make tubes, vessels, tyre yarn, ampoules and components of blood transfusion apparatus.  In typical Example (1) e -cyclohexyl-e -caprolactam was heated with sebacic acid and water in an evacuated vessel. The polymer so formed was extruded as a thread, ground, treated with boiling MeOH and dried.  In Example (4) the extracted low molecular weight material was further polymerized.

Abstract: 1302454 Hydrocarbons ASAHI KASEI KOGYO KK 14 Aug 1970 [14 Aug 1969 25 Aug 1969] 39272/70 Heading C5E [Also in Divisions B1 and C1] Benzene, toluene and polymethylbenzenes are obtained by contacting at an elevated temperature a vapour-phase feedstock containing aromatic hydrocarbons of nine or more carbon atoms and having one or more alkyl groups of two or more carbon atoms as nuclear substituents with a catalyst comprising alumina treated with one or more of MgSiF 6 , ZnSiF 6  and CaSiF 6  to incorporate 0À01 to 10% by weight of fluorine.

Title: Information storage device

Abstract: 918,603. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Nov. 20, 1959 [Nov. 24, 1958], No. 39941/59. Class 40 (4). [Also in Groups XIX and XXXVI] A matrix arrangement of condensers is formed by a horizontal and a vertical set of conductors with a dielectric at each crosspoint, the dielectric at some crosspoints being replaced by a third electrode so that the capacitative coupling at such points is markedly different from those points at which the third electrode is absent. If 1 and 2 are the electrodes, the capacity of the condenser in Fig. 2 is low whereas that in Fig.' 3, where the dielectric 4 is coated with metal is high. Thus if strips of dielectric with parts coated with metal in double 2-out-of-5 code, as shown in Fig. 5, are inserted in the matrix then application of a high-frequency signal to one of the horizontal conductors will produce outputs on selected vertical conductors to indicate 1 out of 100 possible numbers. The matrix may be used in computers or to translate or indicate class of line in telephone exchanges. If the coded output is to be changed for any input line the strip 5 can be changed easily. In a modification shown in Figs. 6 and 7, the horizontal and vertical conductors 1, 2 have triangular enlargements 8, 10 at the crosspoints. The coupling is low in the absence of the metallic area 12 and high in its presence. This arrangement can be effected by printing on a glass base 13 with a metallic screen 14 between adjacent matrices in a stack. The outputs can be amplified by a transistor circuit (Fig. 19, not shown). Specification 682,985 is referred to.

Title: Secondary amines and preparation thereof
IPC: C07C211/27
Filed: 1957-12-30
Abstract: Hydrochloric and sulphuric acids may be removed from protein hydrolysates and hydrochloric and nitric acids from aqueous systems by treating the acid medium with a secondary amine (see Group IV (b)) of the general formula <FORM:0824149/III/1> where R1 is a branched chain alkyl radical containing 9 to 15 carbon atoms, R2 is H or CH3 and R3, R4 and R5 are alkyl groups having a combined total of 7 to 23 carbon atoms.  A 0.1N solution of the amine in kerosene may be used, for example, and the acid recovered by treatment with sodium or ammonium hydroxide or sodium carbonate.  Amines of the above general formula may be used to extract uranium from leach liquors, for example, by shaking a leach liquor containing U3O8, Fe+++ and SO4= with a solution of the amine in kerosene so that the uranium passes into the organic layer and then washing the organic layer with sodium carbonate solution and separating the uraniumrich aqueous phase.  The uranium extraction coefficient (weight of uranium extracted \sS weight of amine required for the extraction) is given for 8 typical amines.  The amines may also be used for the separation of niobium from tantalum, niobium from protactinium and zinc from cobalt.ALSO:The invention comprises mixtures of isomeric amines having the general formula <FORM:0824149/IV (b)/1> where R1 is a branched chain alkyl group containing 9 to 15 carbon atoms, R2 is H or CH3 and R3, R4 and R5 are alkyl groups having a combined total of 7 to 23 carbon atoms.  The secondary amines may be prepared by alkylating benzene or toluene with a compound containing the desired number of carbon atoms for R1, e.g. propylene trimer, tetramer or pentamer, halomethylating the alkyl benzene or toluene, e.g. with chloromethyl ether and zinc chloride and treating the resulting alkyl benzyl halide with an amine of the formula (R3R4R5)C.NH2 to give the desired product. The reaction between the alkyl benzyl halide and the amine may take place in the presence of an alcohol, e.g. isopropanol. The compounds may be used for concentrating uranium in uranium leach liquors and for removing mineral acids from aqueous systems and protein hydrolysates (see Group III).  The examples describe the preparation of (1) nonyl benzyl-t-octylamine by refluxing nonyl benzyl chloride with toctylamine in isopropanol for seven hours. The basic product is worked up in the normal way and a small quantity purified by distillation at 5 mms. pressure.  In a similar manner are prepared (2) nonyl benzyl-t-dodecylamine; (3) dodecylbenzyl-t-octylamine; (4) dodecylbenzylt-dodecylamine; (5) pentadecyl benzyl-t-octylamine; (6) methyl dodecylbenzyl-t-octadecylamine.

In one embodiment Fig. 3, the control rod is supported from a tube 19 whose upper end 23 surrounds a nut 24 and a screw 25, the tube being held attached to the nut by an electromagnet 26. Linear movement of the nut and tube is produced by rotation of screw 25 by a motor (not shown), in ball bearings 35, 36 located in a housing 34. The latter has an extending flange 45 which is supported by three equispaced cantilever beams 46, each carrying two pairs of resistance strain gauges J1-J4 Fig. 4, connected in bridge networks whose outputs are summed to determine the total weight of the control rod and its associated moving mechanism. Any deviation in apparent weight due to jamming or friction is thus noted. In the event of an emergency the electromagnet 26 is de-energized and the tube 19 falls on to a stop 43 on the roof of the reactor container, carrying the control rod with it. In an alternative arrangement Fig. 7, the tube 19 and control rod are moved by a motor 71 through a rack and pinion 63, 64 and bevel gears 66, 67, the load cells being incorporated at 72. In another embodiment Fig. 8 the torque required to rotate the pinion 64 is measured by strain gauge resistors on the shaft 65, connections to the resistance bridge being made by slip rings and bushes or by inductively coupled coils.
