Title: Improvements in electronic circuits
Inventor: POULSON BARRIE KENNETH
IPC: H02P29/00
Filed: 1968-07-26
Abstract: 1,243,406. Control system. INSTRON Ltd. 8 July, 1969 [26 July, 1968], No. 35841/68. Heading G4H. [Also in Division H3] An electronic control system comprises a number of logic modules A, B &c., each having a signal input I/P, at least one reset input connected to a reset line RL, and a load output 0/P and each consisting of a number of NOR gates T, the modules being connected in parallel to the lines RL and SL so that a reset signal is applied through the lines in response to actuation of an input to any module to reset any previously switched on module, the module having the energized input being inhibited from producing any output signal until completion of the resetting. Two embodiments are described. In the illustrated embodiment a threshold amplifier A, is arranged to trigger when signals indicating that more than one module is switched on are received at its input from summing line SL, the output of the amplifier resetting all the modules via line RL. However due to the persistence of the manual input to the second previously switched on module after the resetting operation this second module is switched on again. In a further embodiment, Fig. 3 (not shown), each module is connected to each of the lines RL and SL by a pair of NOR gates in series and one of the NOR gates making up the module is arranged to gate the manual input signal to the module. When a second module is "switched on" a reset signal is applied to line RL and the second module is prevented from switching on by the gating NOR gate until the previously switched on module has been reset. When the previously switched on module resets the input gate in the second module is cleared and the second module switches on. The Specification states that the output from each of the modules may control an electromagnetically actuated clutch, and that further modules, e.g. D, may be added as required. Furthermore the sensitivity of the threshold amplifier in the first embodiment may be adjusted so as to trigger when n or more modules are energized, thereby allowing n-1 modules to produce on output simultaneously.

Title: Record material sensing means
IPC: G06K7/08
Filed: 1957-11-21
Abstract: 864,633. Sensing record cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 21, 1957 [Nov. 21, 1956], No. 36324/57. Addition to 769,857. Class 106 (1). In a machine for sorting record cards data representation e.g. holes are sensed by capacitor elements, one of which extends past a complete row of card columns and the other of which is movable along the length of the first so as to register with any selected column. The capacitance elements are connected in a radio-frequency voltage divider network as described in the parent Specification. In Fig. 2 this circuit is shown in a practical embodiment. A radiofrequency oscillator 35 comprises an oscillator tube 39 and a tank coil 40 with a tuning capacitor 41. The output from the tank coil is taken through a condenser 42 and line 43 to plate 37 which is one of the capacitor sensing elements. The other element 38 is connected to a tuned tank circuit 44, the output of which is passed via a two-way rectifier 47 to produce a D.C. voltage across a load (Fig. 3, not shown), which voltage changes when a perforation passes between plates 37, 38. This change is inverted and combined with a pulse from a " sort selection " commutator rotating with the card feed and used to energize sorting magnets controlling the usual sorting blades. In the form of Figs. 5 and 6 a capacitance sensing element 38 for one column is mounted in a bifurcated mount 79 pivoted at 80 to a support 75 and urged downwardly by a spring 84. A small clearance between plates 37, 38 is maintained in the absence of a card by stop pins 89 on support 75. This support is carried by screw 76 on a bracket 74 which is fixed to a movable member 73. A spring-loaded pad 77 on bracket 74 bears on a rail 78. The fixed sensing capacitor element consists of a rack having 80 teeth 90 with the same pitch as the spacing between columns on a card. A screwthreaded shaft 96 is rotated once to shift the bracket by one column space. In another arrangement a group of ten capacitor elements is movably mounted over the rack-like lower member, each being separated from the next by shield plates. The invention may also be applied to records bearing data marks made in oil, graphite pencil, water, copper and iron. Specifications 242,654 and 661,312 also are referred to.

Title: Process for the manufacture of hexamethylene tetramine and formaldehyde
IPC: C07D487/18
Filed: 1920-12-31
Abstract: 156,136. Traun's Forschungslaboratorium Ges., H. O. Sept. 9, 1919, [Convention date]. Hexamethylenetetramine; formaldehyde. - Hexamethylenetetramine is prepared by oxidizing methane with air or oxygen in the presence of ammonia gas. The mixture of methane, oxygen or air, and ammonia gas in combining proportions may be passed through an isoprene lamp or through a constricted metallic tube which is heated at the constricted part. After condensing the products, the gases may again be led through the apparatus. The tube is made of such a metal as copper, silver, nickel steel, iron, or alloys of iron with tin, zinc, aluminium, or silicon, or of iron with a coating of one of these metals. The tube then acts as a catalyst; but contact material in the form of thin wire or sheets of silver, copper, nickel, or alloys thereof, may be introduced with an iron or steel tube. The reaction may take place under reduced pressure, and the methane may be replaced by natural gas. By reducing the amount of ammonia in the gas mixture to be treated, the product is richer in formaldehyde. The hexamethylenetetramine obtained can be converted into formaldehyde.
Patent GB-774818-A (GB)
Title: Method of wet-spinning artificial fibres of polyvinyl alcohol
IPC: D01F6/14
Filed: 1954-12-20
Abstract: Polyvinyl alcohol filaments are formed by extruding an aqueous solution of the alcohol into an aqueous salt solution whose concentration is 1.5 to 5 times, preferably 2 to 4 times, the "coagulating value."  This value is defined as the percentage ratio of the weight of the salt to the weight of the salt and water in a mixture formed by adding to a sample of the spinning solution, drop-wise and with constant stirring at the temperature of the coagulating bath, just sufficient of the aqueous salt solution to cause the polyvinyl alcohol in the mixture to begin to coagulate, as shown by a sudden decrease in the viscosity of the mixture.  The filaments have a substantially circular cross-section and a relatively homogeneous structure.  The salt may be sodium, potassium, ammonium, magnesium, zinc or aluminium sulphate, sodium or potassium chloride, sodium or potassium nitrate or sodium phosphate or acid sodium phosphate.  The salt may also be used in conjunction with a salt having almost no coagulating effect on polyvinyl alcohol, e.g. ammonium, magnesium or zinc chloride.  The concentration of polyvinyl alcohol in the spinning solution may be 10-35, and preferably 15-30 per cent, the temperature of the coagulating bath may be 5-60 DEG C., preferably 10-40 DEG  C., and the length of the path of the filaments through the bath may be 50 to 300 cm. at a speed of, for example, 0.5 to 100 m./min.  The filaments are passed in the usual manner through a second bath comprising a more than 85 per cent saturated aqueous solution of a coagulating salt, such as sodium or ammonium sulphate, at 40 DEG  to 60 DEG  C.  In an example a 28 per cent aqueous solution of a polyvinyl alcohol is spun into a 9 per cent aqueous ammonium sulphate solution at 35 DEG  C., the filaments being drawn along a 2-metre path of travel through the bath and then through a second bath of 40 per cent ammonium sulphate at 45 DEG  C. for a path of travel of 0.5 metre.  The filaments so obtained are treated first with steam and then with an aqueous solution containing sulphuric acid, ammonium sulphate and formaldehyde. Specification 699,097, [Group II], is referred to.

Filed: 1946-12-17
Abstract: Octyl alcohol is used as a froth-inhibiting agent in the preparation of hafnyl and zirconyl organic co-ordination compounds (see Group IV (b)).ALSO:An aqueous solution of a salt of the zirconyl or hafnyl ion with a strong inorganic acid, e.g. sulphuric, hydrochloric or nitric acid is added to an aqueous solution or suspension of a carbonate, and the reaction mixture is added to an organic acid having an ionization constant greater than that of carbonic acid to form an assumed co-ordination compound of the zirconyl or hafnyl salt of the organic acid with the other salt present. Carbonates of ammonium, sodium, potassium, calcium, magnesium, barium, strontium, beryllium, zinc and lead, and acetic, citric, oxalic, tartaric, &c. acids are specified for use in the reaction. The clear solution obtained is evaporated to dryness at 100-125 DEG  C.  In the second stage of the process, frothing may be prevented by the addition of a little octyl alcohol.  The products are employed for waterproofing, fireproofing, weighting, &c. textiles. Specification 569,054, [Group III], is referred to.
