Title: Process for preparing resins
IPC: C08G8/30
Filed: 1963-09-13
Abstract: Resins prepared by hydrogenating phenol/ dicyclopentadiene/terpene products (see Division C2) are used to make quick-drying (e.g. 6 hours) clear varnishes by boiling with linseed oil/stand oil at 260 DEG  C., diluting with white spirit after cooling, adding Co-Pb-Mn naphthenates and triturating with ZnO, white lead and BaSO4.ALSO:Resinous products are obtained by hydrogenating the phenol/dicyclopentadiene/terpene products of Specification 1,043,159 in presence of a catalyst at above 150 DEG  C., so that partial dehydration takes place.  The starting materials have the formula <FORM:1056877/C2/1> in which R and R1 are terpene hydrocarbon radicals (or R1 is -OH or alkyl) and n is 1-4; it appears that some of the phenolic rings are converted to cyclohexane rings by a hydrogenation -dehydration-hydrogenation sequence.

Abstract: 1528926 Radar display SIEMENS-ALBIS AG 3 Sept 1975 [25 Sept 1974] 36196/75 Headings H4D and H4T Two signals in synchronism with the PRF of a radar are displayed on respective vertically-spaced traces of a CRT with electrostatic deflection by applying each signal via a respective coupling capacitor to a respective one of the Y-plates. The capacitors are alternately switched to oppositelypoled adjustable bias voltage sources to effect the trace separation. In the Fig. 1 embodiment, a bias voltage applied between the Y-plates of the CRT alternates between being positive in one X-time-base sweep and negative in the next. This bias is applied by charging capacitors Cl, C2 from voltage sources El, E2 alternately, by closing switch S1A,B or S2A,B briefly at the beginneing of the time-base sweep. The radar video signal VS is applied, after C1 and C2 have been charged, via gate T and C2 to deflection-modulate the lower trace. Range marker signals DMS are applied via Cl to deflectionmodulate the upper trace. The X time-base is synchronized with the radar PRF.

Abstract: 979,985. Toy vehicles. METTOY CO. Ltd. Dec. 23, 1963 [Sept. 25, 1962], No. 36386/62. Heading A6S. [Also in Division G5] A locomotive toy is electrically propelled along a surface by means of a plurality of electrical windings in said surface fed with A.C. which interacts with a magnet on the vehicle in much the same way as the stator windings of an electric clock react with the magnetic rotor. Preferably the magnet 3 has at least three pole faces 4 which are spaced so they span at least two of the track windings 7 which preferably should be two or three-phase electric current to simplify starting. Alternatively, the frequency may be gradually increased from zero to maximum, thus making the apparatus suitable for a race game. Reversing can be achieved by changing the phase notation of the windings. Oscillatory power may be provided by power transistors from a battery or a low-voltage output transformer.

Filed: 1956-12-03
Abstract: 833,469. Shearing yarns. MACKIE & SONS Ltd., J. Nov. 19, 1957 [Dec. 3, 1956], No. 36897/56. Class 120(3) [Also in Group XXV] A yarn shearing machine has a rotary shearing blade 3 along which the yarn 1 is led and a knot-deflecting device comprising a pair of relatively movable members 8, 9 running along the length of blade 3 outside the path of the yarn, the two members being pressed together and member 9 being shaped at 10 to cross the yarn path at the intake end and thus bear against the yarn and maintain a gap 5 between the members at that end equal to the yarn thickness. As shown, member 8 is in the form of a platform and member 9 consists of a blade vertically movable at both ends and urged downwards by its own weight. The rear end 11 of blade 9 is inturned and cut away. Thus the end 10 of blade 9 rests on the yarn while the other end rests on platform 8. When a knot 15 in the yarn approaches the shearing blade 3, it is deflected outwardly by the portion 10 of blade 9 and passes along the length of blade 9. A spring-biased trigger 20, which is deflected with the yarn, acts to return the yarn to the left of knot 15 to the shearing position. Instead of using trigger 20, inward bias may be applied to the yarn by setting a guide pulley 2 inwardly from the path of the yarn along the shearing blade 3.

Abstract: 1515999 Coupling circuits DORNIER SYSTEM GmbH 8 Sept 1976 [4 Oct 1975] 37209/76 Heading H4R In a single bus transmission system each of a number of transmitting stations is coupled to the bus between a pair of oppositely wound transformer windings W1, W2 connected in series with the bus. Signals originating from the transmitting station are therefore coupled onto the bus whereas signals transmitted along the bus from other transmitters see the coupling as a zero impedance and are not attenuated thereby. To reduce the loading on the transmitting station created by the windings W1, W2 a further winding W3 may be provided which is short circuited whilst the station is transmitting. Figure 4 (not shown) illustrates a further method of compensating for the loading whereby an auxiliary voltage generated by the transmitting station is applied across the third winding W3.

Title: Improvements in or relating to gas turbine plant
Filed: 1938-12-22
Abstract: 525,550. Gas turbines. JENDRASSIK, G. Dec. 22, 1938, No. 37346. Convention date, Dec. 24, 1937. [Class 110 (iii)] A gas turbine plant in which the combustion air is heated by the exhaust gases from the turbine is controlled by varying the inlet temperature of the working fluid and the amount of air passing through the heat exchanger in the same sense as the variation in the lead. The variation of the heat supply is temporarily in excess of that required for normal operation and in the case of sufficiently diminished loads the transfer of heat in the heat exchanger is also over-reduced temporarily. The air from the compressor 1 passes through a heat exchanger 16 before passing to the combustion chamber 24 and the turbine 10. Should the load on the plant fall, the governor 7 will speed up, the rod 45 will be lowered and the fuel supply reduced to a minimum. When the arm 33 reaches the stop 38, the spring 36 will be compressed and the head 37 of the draw-bar 32 will contact the end of the lever 40 and open the valve 42. Since the heat exchanger 16 acts as a heat accumulator the amount of air byepassed will temporarily exceed the normal quantity for the new load condition, but as the exchanger cools down the governor closes down the valve 42 to permit the exchanger to reach its new steady condition... The byepass may be dispensed with and the amount of air passing through the heat exchanger controlled by one or more of the valves 47, 48 and 49, or by having adjustable guide vanes fitted to the air compressor. A valve 50 may be used to control the air supply to the combustion chamber 24 and a thermostat 51 may be fitted to limit the inlet temperature of the gas turbine.

Abstract: 628,004. Dielectric and induction heating. IGRANIC ELECTRIC CO., Ltd. Dec. 19, 1946, No. 37405. Convention date, Dec. 31, 1945. [Class 39(iii)] [Also in Group XXXV] The power output of a high frequency heating oscillator is maintained at a substantially constant value by utilizing any variation of output to expand or contract the resilient coils of a variable inductance in the heating circuit. As shown, the generator comprises a push-pull pair of valves 8, 9 associated with tuned grid and plate circuits, similar to that described in Specification 621906, [Group XXXV]. The article 22 to be heated is supported between electrodes 20, 21 which are connected across a coil 16 having tappings connected to the valve grids and to earth. A resistor 13 in the cathode lead is in parallel with a solenoid 43 which is normally balanced in its action on the switch 27 by a further solenoid 39 carrying a current which may be pre-set by a rheostat 42. The cathode current of the valves is a measure of the rate of heating and when this varies in either sense the switch operates to start a motor M in the direction necessary to restore the balance. The motor operates a screw-and-nut mechanism to expand or contract the coil 16, thus varying the tuning of the load circuit until the rate of heating is again normal. The coil 16 may comprise a thin-walled copper or bronze tube, or a silver-plated copper tube may be slid over a straight rod which is then wound to form a spiral coil. Alternatively a coiled spring of suitable metal or alloy may have a plating of silver deposited thereon. The control system may be applied to inductive heating.

Abstract: 1403996 Biological purification of effluents L'AIR LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 10 Aug 1972 [10 Aug 1971] 37445/72 Heading C1C [Also in Division B1] A process for the production, use and regeneration of a free oxygen-containing gaseous mixture, as for example in the biological purification of effluent comprises subjecting a gaseous oxygen-containing starting mixture to oxygen enrichment after removing from the starting mixture at least part of one or more constituents (other than oxygen) initially present, supplying the oxygen-enriched gaseous mixture to a system which utilizes some of its oxygen and produces a residual mixture containing unused oxygen and a by-product, subjecting the residual gaseous mixture to a regeneration process in which the by-product is at least partially removed to obtain a regenerated mixture, and recycling the regenerated mixture to undergo oxygen enrichment. In the apparatus shown, air or other free oxygen containing gas entering at 1 is compressed at 2, mixed with residual gases from oxidation reactor 32 and passed through one of regenerators 7, 4, 40 to fractionating column 18, the generator having been cooled in an earlier part of its cycle by a flow of cold nitrogen from the top of column 18. The oxygen-rich fraction leaving the column by line 9 is reheated by passage through the regenerators and is fed through line 25 and compressor 33 to oxidation reactor 32. Part of the initial air feed from line 1 is passed through line 5 and carbon dioxide absorbers 30, 31, cooled by heat exchange with waste nitrogen in 27 and fed to the top of fractionating column 18. Each of the regenerators 7, 4, 40 operates with a 3-stage cycle; in forward flow (left to right as shown) carbon dioxide and water are condensed out from the incoming flow of compressed air-residual gas mixture in line 3; in reverse flow first the carbon dioxide &c. is removed by entrainment in a (warmed) flow of nitrogen from heat-exchanger 50, then the oxygen-enriched gas stream in line 9 is rewarmed on passing through the regenerator. In the 2 stage air fractionating column 19, 20, the first zone 19 is operated at a higher pressure than the second zone 20. Two fractions from the first zone 19, an oxygen-rich fraction in line 23 and an oxygen-given fraction in line 24 are cooled in exchanger 50 and expanded and introduced into the second zone 20. The condensed mixture at the bottom of zone 20 is revaporized and heat-exchanged in unit 21 with the top fraction from column 19. Almost pure nitrogen is evacuated from the top of column 20 and almost pure oxygen leaves by line 9.
