Abstract: 922,233. Ornithopters. L. G. WATTS. March 8, 1961 [Dec. 8, 1959], No. 41613/59. Class 4. An ornithopter is characterized by each wing comprising a substantially rigid lift portion 7 of aerofoil section having a flexible trailing wing portion 10 united therewith and a wing tip portion 9 having a rigid leading edge portion 15 connected to rigid portion 7 for flapping movement of the wing tip portion about a chordwise pivotal axis 14, leading edge portion 15 having united thereto a flexible part 16 which is united also with trailing wing portion 10 whereby on flapping movement being imparted to the wing tip portion the flexible part thereof and the trailing wing portion are actuated to impart a forward component of thrust. Rigid portion 7 of each wing is supported by a spar 11 extending transversely from the fuselage and flexible portions 16 and 10 are supported respectively by tubular ribs 17 extending from spar 18 and by ribs 20 from spar 11. Flapping movement of tip portions 9 is achieved by fore-and-aft movement of two control columns 29, each operating a pair of master cylinders 32 connected by pipelines 34 to slave cylinders 35. The rudder 44 and elevator 42 are controlled respectively by a foot control 45 and by lateral movement of control columns 29. In an alternative embodiment, the tail unit is dispensed with, and directtional control is achieved solely by flapping of the wings. In this case, each wing tip portion is connected by a universal joint to its corresponding rigid lift portion, and compound angular movements of the wing tip portions are controlled through master and slave cylinders by rotary movement of a single control column.

Abstract: 1504851 Vehicle electrical systems DAIMLER-BENZ AG 13 Oct 1976 [28 Oct 1975] 42560/75 Heading H2H A vehicle electrical system comprises one or more lamps which indicate various operational functions of the vehicle together with means for automatically monitoring the functioning of the lamps. A vehicle electrical system comprises a battery 1 charged by means of an engine driven alternator/rectifier unit 2, the output terminal D + of the unit 2 being connected to the battery by way of a charge indicating lamp 4. The system includes one or more additional indicating lamps, one of which, 5a indicates the vehicle oil pressure. A series circuit including the lamp 5a, resistor 5c and a diode 5d is connected between the positive terminal of the battery, by way of the ignition switch 8, and the output terminal D + of the alternator/rectifier unit 2, the diode 5d conducting towards the terminal D+. With the unit 2 at rest, closure of the ignition switch 8 applies the battery voltage to the series circuit 5 and the lamp 5a is illuminated with diminished brightness due to the resistor 5c. As the unit 2 is driven the lamp 5a is extinguished due to the generated voltage at the terminal D + . Should the oil pressure fail a monitoring switch 5b automatically closes whereupon the lamp 5a is illuminated at full brightness indicating the failure. Units 6, 7; similar to the unit 5, indicate other operational functions of the vehicle and may each contain two lamps either in series or in parallel.

Abstract: 1509789 Separating gases AIR PRODUCTS & CHEMICALS Inc 17 Oct 1975 [27 Nov 1974] 42731/75 Heading F4P In a method of separating the C 2  hydrocarbons from a mixture comprising hydrogen, methane, ethane and ethylene, the feed gas is partially condensed in dephlegmator 27 cooled by indirect heat exchange, the condensate being fed to a rectification column 16 from the base of which a liquid product stream of C 2  hydrocarbons is withdrawn. The compressed feed gas is precooled at 11 and partly condensed at 13, the gaseous fraction being fed to dephlegmator 27, and as some of this condenses it flows back down to separator 13. The gas mixture leaving 27 is cooled at 30 and fed to separator 32, the overhead from which is withdrawn. The liquid stream from separator 32 is expanded at 35, warmed at 30, and used to cool dephlegmator 27 before being work-expanded at 40, warmed at 25 and recompressed at 43. Gaseous overheads from column 16 are partially condensed, the liquid being recycled, the gas being cooled at 25 and expanded at 58 and added to the stream from heat exchanger 30. In a modification, Fig. 2 (not shown), the liquid stream from separator 32 is warmed and fed to column 16, and some of the condensed gas overheads from column 16 are cooled, expanded and warmed then added to the stream cooling dephlegmator 27. The latter is additionally cooled by evaporating ethylene in coils 28.

[Also in Division C5] Synthetic polyamide filaments are lubricated with an aqueous emulsion which contains 1-20 wt. per cent of a mixture comprising 60-75% mineral oil, 3-7% of a lithium salt of a C 11 -C 15  saturated, branched-chain fatty acid (e.g. isotridecane acid) and 20-25% of an emulsifying agent (e.g. a mixture of the reaction product of ethylene oxide and a fatty alcohol and the reaction product of oleic acid and mono- and di-ethanolamine). The emulsion may also contain a filament bonding agent e.g. a mixture of sodium N-oleoyl sarcoside and 2-ethylhexyl stearate. Example 1 describes the treatment of 20 denier, brilliant monofilaments of poly-#- caprolactam at the spinning machine with a 10% emulsion of a mixture of (a) 75% mineral oil+lithium isotridecanate (in wt. proportions 70: 5) + (b) 25% of a mixture of 33 parts of an ethylene oxide reaction product with C 12 -C 18  fatty alcohol and 50 parts of the reaction product of oleic acid and a mixture of mono- and diethanolamine (in wt. proportions 1:2). The filament was drawn off at 850 m/minute and subsequently stretched at 670 m/minute. Example 2 describes the treatment of multifilpolyamide fibres with a 10% emulsion of 65% (a) 25% (b) and 10% of a mixture of equal parts of sodium N-oleoylsarcoside and 2-ethylhexyl stearate. The filaments were drawn off at 850 m/minute and stretched at 450 m/minute. Example 3 describes the treatment of monofilaments of poly-#-caprolactam which were spun through double-hole dies for massive profiles as in Example 1 with a draw off stretching speed of 560 m/minute.
