[Also in Divisions F1 and F2] An aircraft comprises a primary lifting surface 11 (Fig. 2, not shown), an air breathing jetpropulsion engine having a propulsion nozzle 28 (Fig. 4, not shown) and an intake defined between an underneath surface 15 of the aircraft and an intake lip 24, and an engine housing projecting below the surface 15 and having a substantially flat undersurface 23 whose leading edge constitutes the lip 24 and whose trailing edge constitutes the nozzle lip 25, and is characterized in that the undersurface 23 is at a greater incidence than the primary lifting surface such that at the design cruising speed (e.g. Mach 7) the ratio of its lift to its induced drag is substantially equal to the ratio of lift: total drag of the primary lifting surfaces. As described, a ram jet is provided, and has a nozzle 28 whose upper surface is concave and extends upwardly into the primary lifting surface, and which is so disposed that the thrust vector is inclined to the horizontal by slightly more (e.g. one degree) than the undersurface 23. The aircraft configuration is such that the resultant of the intake momentum drag, the engine thrust and the aircraft lift passes behind the centre of gravity. A gap 26 is provided between the leading edge of the intake ramp 20 and the surface 15 to allow boundary layer air to escape the intake and to be discharged through openings 26a.

Abstract: 1,053,190. Optical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 29, 1964 [Nov. 6, 1963], No.44068/64. Heading G2J. [Also in Divisions G1] and H4] Apparatus for analyzing the emission or absorption spectrum of a substance includes an optical filter arrangement whose radiation transmission frequency varies with respect to time. A polychromatic light source 1 may be arranged to direct light through the filter arrangement 3 to a flow cell 5 for the substance under investigation, the radiation transmitted through the cell falling on a photo-electric detector 7. A mask 26 limits the area of the cell viewed. The filter arrangement consists of an input collimating lens directing a parallel beam of light through sonic delay line 14 and wedge interference filter 18, the frequency of the light passing through which is a function of distance along the filter, to a second lens 22 bringing the light to a focus on mask 24. When a pulse 15 is propagated along the delay line from piezoelectric driver 16 to the far end 14b light is refracted in the region of the pulse and radiation of a frequency capable of passing through the adjacent part of filter 18 passes out of the arrangement 3 beyond the limits of mask 24. A compensating mask 20 is included to compensate for non-uniformities in the filter and optical system. Pulsing of driver 16 may be synchronized with operation of distributor 81 directing the detector outputs corresponding to differing wavelength ranges to different inputs of an analyzer. A slotted mask may be placed adjacent to filter 18 to more closely define the wavebands involved. If elements 5 and 26 are removed the arrangement may be used to investigate a radiation source. If the source is a sample which only emits radiation during a limited time synchronization of the pulse at driver 16 and the initiation of the reaction causing radiation from the source may be effected.

Composite filaments of the eccentric sheathcore type which undergo crimping when immersed in water, particularly hot water, are produced by extruding simultaneously through each extrusion orifice of a spinneret adapted for the melt-spinning of eccentric sheath-core filaments a melt of a homopolyamide (to form the sheath) and a melt of a copolyether amide (to form the core), which has been produced by polycondensation of adipic acid with 75 to 20 mol per cent of an ether diamine having the formula H 2 N-(CH 2 ) 3 -R-(CH 2 ) 3 -NH 2  in which R represents either -O-, or -O-(CH 2 ) n -O- in which n is 2 to 4, and 25 to 80 mol per cent of hexamethylene diamine. The two polymers shrink to different extents when immersed in water, particularly hot water. The sheath may consist of polyhexamethylene adipamide, polycaprolactam, or polyaminoundecanoic acid. The composite filaments formed may be cold-stretched, e.g. at a stretch ratio of 3À5 : 1. The ratio by weight between the sheath and core of the composite filaments may be between 30 : 70 and 70 : 30, preferably 50 : 50.

Plural insulated contacts 57 bracketed to body 29 are engaged by spring- loaded two-contact plate 61 carried by rod 40, to switch circuits of the electronic control unit in response to rod position. Non-magnetic bolts 64 passing through bores of the body 29 engage the armature 22 and carry insulated contacts 67 resiliently engaging others of contacts 57 switchably indicating armature position to the control unit, and a tongue 70 engaging a groove of shaft 40 prevents rotation. With rod 40 in extreme L.H. position, a current impulse to windings 17 draws armature to abut core 28, and R.H. pawls 42 carry rod 40 to the right by one step, while the L.H. pawls are disengaged. Contacts 57, 66 signal armature position to the control unit, which de-energizes winding 17 so that the armature recentres with disengagement of the pawls. The rod 40 is displaced further to the right or thereafter to the left by similar operations involving energization of coil 17 or coil 18. The armature may be magnetically polarized, and the windings energized to produce opposed magnetic fields.
