Abstract: 1,159,568. The antibiotic primycin. CHINOIN GYOGYSZER-ES VEGYESZETI TERMEKEK GYARA RT. 14 Oct., 1966 [20 Oct., 1965], No. 46130/66. Heading C2A. The antibiotic primycin is produced by culturing a primycin-producing strain of the species Micromonospora galeriensis, e.g. No. 650,707 (Hungarian Institute for Public Health) in an aqueous nutrient medium. The temperature is 27 to 40 C. and the pH is 6 to 9; cultivation is for 96 to 100 hours. The fermentation broth is adjusted to pH 5 to 7 and heated at 70-90 C. to precipitate the primycin, which is centrifuged along with the mycelia. The separated solids are repeatedly extracted with a mixture of polar solvents, e.g. 80% aqueous methanol and the solvent extracts concentrated and cooled to allow the primycin to separate. The crude may be purified by precipitation with lead salts followed by treatment with activated carbon, calcium carbonate or fuller's earth.

Abstract: 1412380 Triangular wave generators; pulse modulation PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Oct 1973 [6 Oct 1972] 46168/73 Headings H3P and H4L In a triangular wave generator, of the type in which a charging current for a capacitor is reversed by means S each time the capacitor voltage reaches an upper or lower limit and in which the forward and reverse charging currents are controlled in magnitude by respective control voltages, one control voltage is derived from the other, U1, by dividing at 2 the product obtained at X of the voltage U1 and an auxiliary voltage UH by the difference between these vlotages obtained from 3. The duty cycle may thus be varied without varying the frequency. If (as in Fig. 4, not shown) the voltage U1 is derived by multiplying UH (at 5) by the ratio of a voltage (UE) to a duty-cycle control voltage UT, the voltage UE will vary the frequency without varying the duty cycle. The voltage US controls the output wave amplitude and if (as in Fig. 5, not shown) UH is derived by multiplying US by a frequency control voltage (Up) the amplitude may be varied without altering the frequency by varying the voltage UF.

Filed: 1974-10-29
Abstract: 1480629 Detecting ice and moisture electrically SURFACE SYSTEMS Inc 29 Oct 1974 [5 Nov 1973] 46835/74 Heading G1N(A) A system for detecting wet and icy conditions on road surfaces comprises a capacitor C1 and two stainless steel strips 35, 37 forming an electrical conductivity sensor 39, Fig. 4, which are exposed to atmospheric precipitation and a further capacitor C2, not so exposed, mounted on the underside of printed circuit load 31, means 7 and 11 for supplying first electrodes of the capacitors with out of phase signals and an electrical logic circuit 45 which indicates icy conditions when the resultant signal at the commoned second electrodes C15, C25 exceeds a predetermined limit indicating any precipitation and concurrently the output voltage of the sensor circuit 43 exceeds a predetermined limit indicating ice formation. Predetermined limits indicating surface water, water and ice mixed, and ice alone are set on potentiometers P3, P4, and P5 respectively. In dry conditions comparator 57 gives a zero output and inverter 63 gives a "clear" signal. In wet conditions an output from comparator 57 and zero outputs from comparators 59 and 61 fed through invertors 69 and 71 respectively cause AND gate G4 to produce a "wet" signal. At inception of freezing outputs from comparators 57 and 59, the latter fed through invertor 73, cause AND gate G5 to produce an "alert" signal. Under conditions of ice outputs from comparators 57, 59 and 61 cause AND gate G6 to produce an "ice" signal. When, due to the presence of salt on the surface, the output voltage of the capacitance circuit 41 exceeds the voltage applied by potentiometer P6 to the other input of comparator 53 a voltage is added to that supplied by battery 51 across the conductivity sensor 39 and resistor R3. This increase in voltage compensates for the otherwise lower voltage drop across the sensor 39 due to the presence of salt.

IPC: A43D11/03
Filed: 1963-11-26
Abstract: A method of stiffening the toe or counter of a shoe upper comprises incorporating stiffening means comprising an elastomeric copolymer of ethylene and vinyl acetate.  In a first embodiment a molten mass of the copolymer is applied directly to the inner surface of the upper and is allowed to form a continuous layer firmly bonded to the upper. The upper may be lasted before the copolymer is cool, or the copolymer may be allowed to cool as a flat sheet and is subsequently softened by heat for the lasting operation.  In a second embodiment a stiffener of suitagle outline shape may be cut out e.g. by a die, from a sheet of the copolymer and skived along its margins or may be formed by compression or injection-moulding the copolymer.  The stiffener may be coated on one side or both sides with a pressure-sensitive or heat- or solvent-activatable adhesive.  The stiffener is then stuck in position on the inside of the upper using a press and the upper is pulled over a last, heated by a conventional steam heating unit used to condition the upper for lasting and then lasted. Alternatively the upper may be heated and the pulling over and lasting performed in a single operation.  When the stiffener is used in an unlined shoe it may be laminated with a light cloth carrying a coating of flock.
