Title: Improvements in or relating to fan ducts for gas turbine ducted fan engines
Inventor: BILLINGER BRIAN ARTHUR
IPC: F02K1/72
Filed: 1968-08-08
Abstract: 1,247,691. Thrust reversers. BOLLS-ROYCE Ltd. 8 Aug., 1968, No. 37881/68. Heading B7G. A ducted fan gas turbine engine has thrust reversing o spoiling means comprising two sets of flaps whose members are spaced alternately around the circumference of the outer wall of the fan duct, the members of the first set of flaps being pivotable about their downstream ends to meet the inner wall of the duct and thus to obturate the duct, the second set being translatable parallel to the axis of the duct so that this motion of the two sets of flaps exposes an annular gap in the outer duct wall. In Fig. 1, the duct for air from fan blades 14 of a gas turbine engine 10 is defined by inner wall 12 and an outer wall 16, spaced apart by members 18. The outer wall 16 comprises three parts, fore and aft fixed parts 22 and 26 and a movable part 24. Pivotally attached at 46 to brackets 34 on the movable part 24 are the fore ends of the members of the first set of flaps, 38, so that when the movable part 24 is translated by rams 30 to the position shown dotted the flaps 38 are also moved. These flaps are pivotally attached at 42 to fixed wall part 26, and also have pivot points adjacent their mid-lengths, so that ram 30 pivots them to the duct obturating position shown dotted. The second set of flaps, 40, whose members are pivotally connected at their forward ends to the members of the first set of flaps are also moved by ram 30 to the position shown dotted. Guide vanes 36 supported on members 28, Fig. 1, may be provided to direct the flow of gases forwardly from the annular gap in the obturated duct. For clarity, the vanes and supports are omitted from Fig. 3. Since the circumference of wall 12 is less than that of wall 16, the members of the first set of flaps, 38, are tapered to allow close fitting when the duct is obturated. The shape of flaps 38, their connection to wall parts 24 and 26, and to the second set of flaps, 40, are seen in Fig. 3. Not shown in Fig. 3 are supporting pins which pass through slots 56 in the raised spines of the members of the second set of flaps 40, the pins being mounted on brackets attached to fixed part 26. These pins support the downstream ends of the flaps when in the Fig. 3 position, and the slots 56 allow translation of the supported flaps as in Fig. 6 (not shown).

Title: Process control arrangements
IPC: H04L5/20
Filed: 1971-08-06
Abstract: 1360605 Data transmission systems; semiconductor switching circuits PLESSEY CO Ltd 6 Aug 1971 [6 Aug 1970] 37912/70 Headings H4P and H3T A double-current digital transmission system employs equal currents in both wires to avoid return earth currents and therefore cross-talk from them. A so-called marker module 1, say a computer processor, transmits to one of a number of slave modules 2, e.g. stores. A standing line current of i/4 flows in each wire 3, 4 in opposite directions from sources +V, -V to earth, or, and over resistances R5, R6 and R4, R3, but which cancel in terminating resistances R7, R8. On sending a mark signal from module 1 switches S1 and S2 close to send current i to each wire from constant current sources CS1, CS2 again, resulting in, a current of i/4 in each of resistors R3, R4, R5, R6, but in the opposite directions, producing a change (reversal) in the potential difference between wires 3 and 4 which is detected in differential amplifiers 2 in the slave modules. Transmission from a slave to the master module over a separate pair of wires employs similar components (Fig. 3, not shown). The current sources CS1, CS2 and switches S1, S2 may be provided by the transistor circuit shown in Fig. 4. Antiphase signals applied simultaneously to T1, T2 switches on T3, T4 to supply the double current signals.

Title: Vaccines against Measles and process for their manufacture
IPC: C12N7/00
Filed: 1966-08-25
Abstract: 1,161,414. Measles vaccines. BEHRING- WERKE A.G. 25 Aug., 1966 [28 Aug., 1965], No. 38126/66. Heading A5B. Measles vaccine is prepared by successively cultivating measles, virus obtained from a human source, in at least five primate cell tissue cultures, each culture comprising the same type of cells, and processing the resulting virus into a vaccine in a conventional manner. Suitable cell cultures are those of monkey or human embryo tissue, e.g. heart, muscle, testicles, skin, spleen, tonsils, thyroid, annion or chorion, or human diploid cells. Up to twenty successive cultivations may be employed. The cultivated virus is processed into a vaccine by inactivation with formaldehyde or treatment with ether and a non-ionic surfactant, e.g. polyoxyethylenesorbitan mono-oleate or mono-stearate, alkyl-phenol polyglycol ethers, ethylene oxide-higher alcohol or -fatty acid condensates,. or sodium desoxycholate. When processed with such a surfactant, the measles vaccine may be combined with pertussis antigens and additionally with other vaccines, eg. diptheria and/or poliomyelitis and/or tetanus. An adjuvant, such as aluminium hydroxide or phosphate, is preferably added to the measles vaccine or combined vaccine. '

Title: Improvements in electrical power supply arrangements
Inventor: BECQUE PETER JAMES
IPC: H02H3/00
Filed: 1962-10-09
Abstract: 1,065,052. Transistor switching circuits. COAL INDUSTRY (PATENTS) Ltd. Jan. 9, 1964 [Oct. 9, 1962], No. 38214/62. Heading H3T. [Also in Division H2] A protective arrangement for a supply system for control circuits, e.g. of a mining machine (see Division H2), comprises a Wheatstone bridge circuit (Fig. 4) with a stabilized voltage supply connected across one pair of diagonally opposite points of the circuit and a transistor balance detector connected across the other pair of diagonally opposite points. The neutrals of two three-phase intrinsically safe supplies are connected to points Y and Z in the 4th arm of the bridge so that a short circuit between any conductor of one supply and any conductor of the other supply will short-circuit a resistor R25 arid unbalance the bridge. When this occurs, a relay BLA is operated to effect the cutting off of all the supplies. If the supply system includes an intrinsically safe D.C. supply, the positive conductor of this supply is connected to point X so that a short-circuit between this supply and one of the three-phase supplies will result in the short-circuiting of the resistor R26, or of resistors R26 and R25. The various supply conductors may have earthed screens and the resistor R27 may be mounted remotely so that any earth fault or open circuit will unbalance the bridge. The intrinsically safe D.C. supply may be provided with the over-voltage protective circuit shown in Fig. 3. In this circuit a stable reference voltage is applied to base of a transistor VT21 by Zener diodes MR20, MR21 supplied via a resistor R6. The emitter of a transistor VT19 is held at this reference voltage level so that transistors VT19, VT20 and VT22 are normally non-conducting. Should the voltage of the protected - 20 v. line rise, VT19 conducts so causing VT20 and VT22 to conduct. A relay RLN is now energized and opens its contacts N1, N2. Transition from the non- conducting to the conducting state is assisted by voltage feedback through a resistor R86.

Title: Improvements in fabric coating composition and method of preparing same
IPC: D06M15/17
Filed: 1928-12-29
Abstract: 303,368. Du Pont de Nemours & Co., E. I., (Assignees of Gocher, W. S., and Parrett, A. N.). Dec. 31, 1927, [Convention date]. Paints.-Coloured protective finishes are produced on rubber-coated and other fabrics by the use of a hydrocarbon oil obtained by heating asphalt, petroleum residue, stearin pitch or other bituminous materials to a temperature such that decomposition occurs and an oil distils off which is then bodied and fractionated. The oil is usually brownish in colour and of fluid nature, and this oil is chemically unsaturated and contains constituents of varying boiling points. On application to a rubber coated fabric and baking, a finish which does not crack or peel is obtained. In one example, a straight run Mexican flux oil is distilled in a cracking still. The distillate is heated in an open container until it loses about 35 per cent of its original volume and reaches a suitable viscosity. The pigments comprising 7.5 parts by weight of chrome green, 4 parts chrome yellow, and 2.65 parts of iron oxide are mixed in a ball mill with 2.8 parts of solvent naphtha, and 11.7 parts of China wood oil, and mixed with 71.2 parts of treated asphalt distillate. This varnish is applied to black carriage cloth and vulcanized for 2¢ hours at 250‹ F. Part or all of the drying oil may be replaced by asphalt, petroleum flux, or other bituminous materials. For example, the varnish may contain 27 parts of pigment, 85 parts of asphalt oil, 8 parts of drying oil, 12 parts of petroleum flux, and 8 parts of gasoline; or alternatively, 25 parts of pigment, 80 parts of asphalt oil, 6 parts of drying oil, 12 parts of petroleum asphalt and 10 parts of gasoline. The composition may comprise asphalt oil, pigment, bituminous materials (asphalt, petroleum residues &c.) and a thinner. Examples are (1) 30 parts of pigment, 90 parts of asphalt oil, 20 parts of petroleum and 12 parts of gasoline ; (2) 50 parts of pigment. 100 parts of asphalt oil, 16 parts of petroleum asphalt, and 12 parts of thinner. The varnish may be applied to fabric coated with rubber, bituminous compositions, or drying oil compositions. The proportions of the ingredients may vary between 40 to 85 per cent of asphalt oil, 10 to 40 per cent of pigment, and 5 to 30 per cent of combinations of bituminous material and drying oil. Coloured rubber coated fabrics may be made by this process.
