Title: 3,6-Pyridazine-Diol Derivatives and their use in the Preparation of Nutriments
IPC: A23K1/16
Filed: 1966-11-29
Abstract: 1,157,820. Nutrient compositions. CHINOIN GYOGYSZER ES VEGYESZETI TERMEKEK GYARA RT. 29 Nov., 1966 [17 Dec., 1965], No. 53474/66. Heading A5B. [Also in Division C2] Nutriments, which increase the appetite and the utilization of nutritive value, may be obtained by adding 3,6-pyridazine diol or an organo tropic salt thereof to a fodder and/or watering composition. The 3,6-pyridazine salts employed are suitably those formed with alkali metals, ammonia and organic bases and are preferably the double salts of 3,6-pyridazine diol formed with salts of amino acids, suitable amino acids being glycine, alanine, aspartic acid, glutamic acid, histidine, serine and cysteine in the form of salts with alkali metals, dialkylamino alkanols, dialkylamines or other tertiary amines. The fodder compositions may be prepared by admixing the finely ground pyridazine derivative with the basic fodder which may be an animal fodder, preferably a fattening fodder either by itself or in the form of a fodder concentrate. The pyridazine derivative is suitably employed in such amount that domestic animals receive a daily amount of 5-50 mg./kg body weight thereof. The pyridazine derivative may also be employed in the form of a premix, containing 5-90% by wt. of said derivative, which may subsequently be diluted with basic fodder, said premix optionally containing carriers, e.g. fodder grains or products of the milling industry, or other additives, e.g. vitamins, mineral salts, trace-elements, chloline and antioxidants, and the pyridazine derivative may also be added to the fodder in the form of coated pills or granules. The watering compositions may be prepared by dissolving water-soluble salts of 3,6-pyridazine diol in liquids suitable for watering, e.g. water, milk of whey. Many ingredients which the basic fodder may contain are listed.

Title: Simulated leather fabric
IPC: D06N3/00
Filed: 1969-10-31
Abstract: 1291272 Laminated imitation leather PRODESCO Inc 31 Oct 1969 [20 Feb 1969] 53490/69 Heading B5N [Also in Division D1] An imitation leather having a grained surface comprises a knitted base fabric provided with projecting loops, to which loops is bonded a plastics film in which a grained effect is developed by activating contractile forces in the fabric. The base fabric comprises two yarn systems 21, 22 which may be knit in a tricot pattern; at least the yarn 21 is thermoplastic. The yarn 21 is knit to give a flat structure having loops 23 and underlaps 24, while the yarn 22 is overfed to form the projecting loops 25 and underlaps 26. Yarn 21 may be nylon and yarn 22 may be rayon or nylon. Yarn 22 may be a low-twist multifilament yarn of greater denier than yarn 21. A latent contractile force is developed in the yarn 21 by dry-heating, e.g. at 400‹ F. for 4-6 seconds, whilst stretching, thus causing partial crystallization. The plastics film is then applied to the loops 25, e.g. by deposition from a release paper after formation thereon, and cured or stabilized by heating. The film may be provided with a tie-coat to ensure bonding only to the loops 25. The release paper may be provided with a grain or pigment-loaded indentations to give secondary surface effects on the film. After application of the film, the fabric is heat treated to contract it and thereby develop deep wrinkles in the film resembling the grain of natural leather. Such treatment may be by agitation in boiling water followed by dry heating in a tumbler or an autoclave, and cooling. The base fabric may be dyed before the first heat-treatment and the dye stabilized thereby; alternatively the product may be dyed during the final agitation step.

Abstract: 1,242,600. Conveying oscillatory motion. AGFA-GEVAERT A.G. 15 Nov., 1968 [16 Nov., 1967], No. 54337/68. Heading F2Q. [Also in Divisions G2-G3] A drive mechanism for pivoting a member such as a filter or a shutter blade rapidly through an arcuate path (e.g. to open and close the exposure aperture of a photographic printing apparatus) is actuated by a rotary solenoid 1. On the spindle 3 of the solenoid is mounted a toothed sector 4, which meshes with a pinion 5 cut in a spindle 6 supported on a base-plate 2. The spindle 6 carries a crank arm 7 having a pin 8 at one end. Pin 8 engages in a slot 9 in a lever 10, the lever being supported from plate 2 by a pivot (11, Fig. 2, not shown). The shutter blade 12 is firmly secured to the lever 10. Fig. 1 shows the rest position, in which the light passage aperture 16 is uncovered, and an exposure can be made. To terminate the exposure the solenoid is energized, so that sector 4 rotates clockwise. Consequently, pinion 5 and crank 7 rotate anticlockwise, and pin 8, engaging in slot 9, causes lever 10 and hence shutter blade 12 to rotate clockwise to cover the exposure aperture 16. To initiate a new exposure, the solenoid is de-energized.

Abstract: 1360957 Spark-erosion PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Dec 1972 [8 Dec 1971] 56050/72 Heading B3V An apparatus for detecting arcing during a spark-erosion process comprises means 34 for comparing the no load voltage time of each discharge with a reference time interval, a counter 38 for counting the number of consecutive discharges having no load voltage times less than the reference time interval and a comparator 39 for producing an error signal if the number exceeds a predetermined value. The spark gap 1, 2 is connected to a power source 3 via a switching transistor 4 which is controlled by two monostable multivibrators 8, 9 via an amplifier 10. The multivibrator 8 is controlled by a current discriminator 7 to supply a pulse P 1  for controlling the duration of the machining discharge whilst the multivibrator #1 is triggered by the trailing edge of the pulse from the multivibrator 8 to produce a pulse P 0  for determining the cut off time of the transistor 4. The pulse P 0  is fed, via an element 33 for increasing its duration by an amount equal to the reference time interval, to a logic gate 34 having another input supplied with the pulse P 1 . If the pulse P 1  appears before the delayed trailing edge of the pulse P 0 , a counting pulse is produced which is fed to a counter 38. If a number of consecutive counting pulses occur which exceed a predetermined number set by an element 40, an output signal is produced from a comparator 39 and applied to a multivibrator 42 which applies a pulse to the multivibrator 9 to increase the interval between the discharges. The counter 38 is reset to zero by the output from the comparator 39. The pulses P 0 , P 1  are also applied via inverters 36, 37 to a logic gate 35 which produces an output signal for resetting the counter 38 to zero when an acceptable discharge is produced.

Title: Glove boxes or similar containments

Abstract: 1423840 Glove boxes BRITISH NUCLEAR FUELS Ltd and UNITED KINGDOM ATOMIC ENERGY AUTHORITY 23 Nov 1973 [11 Dec 1972] 56987/72 Heading B4Q [Also in Divisions F3-F4] A containment by which a space is segregated from its surrounding atmosphere, e.g. a glove box, is provided with an extract system for the atmosphere of the containment including a vortex amplifier venting into the system, the vortex amplifier having its main inlet in fluid flow connection with the containment and a control inlet in fluid flow connection with the surrounding atmosphere. As shown, a glove box 1 has an air inlet 2 fitted with a filter 3 while an outlet 4 fitted with a filter 5 is connected as the main flow inlet to a vortex amplifier 6 having a control flow inlet 7 fitted with a filter 8 and an outlet 9 to a duct 10 provided with an extractor fan (not shown). A by-pass line 11 fitted with a filter 12 and a variable restrictor 13 connects the interior of the glove box 1 with the duct 10. Under normal conditions the only flow through the amplifier 6 is that through the control inlet 7 and this blocks off completely the main amplifier flow from the glove box 1. In the case of a small leak somewhere on the glove box, there will be a tendency to reduce the box depression. However this reduction means that less control flow is induced into the amplifier 6 and consequently a flow can then take place through the filter 5 and the amplifier 6 to the duct 10. This system uses the amplifier 6 as a standby safety circuit whereby the filter 5 can remain in an "as new" condition until a leak occurs.
