Title: Method and apparatus for ejecting ejection seats from an aircraft cockpit
IPC: B64D25/10
Filed: 1971-04-19
Abstract: 1342912 Ejector seats STENCEL AERO ENG CORP 19 April 1971 [2 Feb 1970] 20731/71 Heading B7G Seats 14, 16, Fig. 1, ejected from an aircraft cockpit 12 are caused to diverge by the application of forces 24 which cause rotations 26, 28 of the seats in opposite senses about the irrespective yaw axes, the rotations being subsequently cancelled by the application of forces 30 in order to permit the separation of the occupants P, P<SP>1</SP> from their seats in safety after rotation thereof has ceased. The forces may be obtained by sequentially tensioning lines 46, 52, Fig. 4, which are attached to the guide rails 20 of the seats. Line 46 is first tensioned and gradually withdrawn from contact with the seat as in U.S.A. Specification 3,563,498, thereby providing force 24; as line 46 runs out, line 52 becomes taut to provide the cancelling force 30. In alternative embodiments, the forces are provided by opposed yaw rockets (Fig. 6, not shown), line 46 in co-operation with the canted nozzle of the main rocket 18 (Fig. 7, not shown), or by means of dual seat bucket mounted sustainer rockets which are sequentially ignited (Figs. 10-12, not shown). A drogue parachute may be attached to the seat to ensure stability thereof (Figs. 8-9, not shown).

Abstract: 531,336. Impedance networks. STANDARD TELEPHONES & CABLES, Ltd. July 18, 1939, No. 20870. Convention date, Sept. 24, 1938. [Class 40 (iii)] The arms of a lattice filter each comprise two or more crystals X associated withinductances L and shunted by tuning condensers C, the elements being tuned to different frequencies so that the filter may have a wide pass band and a wide range of sustained high attenuation. When the inductance is in series with the crystal and condenser, as shown in Fig. 1, each such combination is equivalent to a pair of series-resonant circuits, Fig. 5, and the frequencies are so chosen that the resonances and antiresonances of the series arms Z 1 , Fig. 1, of the lattice coincide in the pass region with anti resonances and resonances of the diagonal arms Z 2 , Fig. 6 (not shown), so as to form a confluent filter. The seven peaks of attenuation, which occur when Z 1 =Z 2 , may be located some above and some below the pass region, Fig. 7 (not shown), or all above, or below it. Alternatively some critical frequencies may-be located outside the pass band for: the purpose of improving the image impedance. In a low-pass filter; Fig. 8 (not shown), a shunt inductance is added to the series arm Z 1 , and in a high-pass filter, Fig. 15 (not shown), a shunt capacitance is so added. Alternatively the inductances L may be in shunt with the crystals, Fig. 12; each combination LCX is then equal to a pair of antiresonant meshes in series, Fig. 13 ; (not. shown). A series inductance is added to the series arm in a low-pass filter, Fig. 12, and a series capacitance is so added in a high-pass filter, Fig. 18 (not shown). The series arms or diagonal arms'of a filter of the kind described may be of different but equivalent, types.

Abstract: <PICT:0837285/IV (a)/1> <PICT:0837285/IV (a)/2> Synthetic linear high polymers are meltspun to form filaments and like products through a spinneret having one or more extrusion orifices, the cross-section of each of which constitutes a main narrow elongated slot communicating with a number of slots spaced apart from one another along the length of the main slot, the length of each of said laterally-extending slots being a multiple of the width of the main slot.  Each orifice may have a total cross-sectional area of 0.05-0.25 sq. mm. and the width of the main slot and of each of the laterally-extending slots may be greater than 0.04 mm. and is preferably between 0.05 and 0.08 mm. The main slot may be rectilinear or may be curved over its length and may be in the shape of an arc of a circle or a part of a spiral, the lateral slots extending radially from the main slot. The lateral slots can form a continuous passage across the main slot or can be in staggered relationship to one another, as shown in Figs. 1 and 2. They may be of the same or different lengths and may be curved or rectilinear.  The width of the slots shown in Fig. 2 is 0.06 mm., the lengths of slots 4 and 5 are 0.40 and 0.15 mm. respectively and the radius of the arc-shaped main slot 3 is 3.5 mm.

Abstract: 405,288. Hydraulic transmission of power. KENT, Ltd., G., 199, High Holborn, London, IVANOFF, A., and HOWARD, G. P. E., Biscot Road Works, Luton. July 28, 1932, No. 21313. [Class 69 (ii).] Speed-regulating means for a hydraulic coupling of the F÷ttinger type operate means for controlling the liquid content of the coupling in such a manner as to cause an excessive change in the liquid content followed by a return towards the original value. In the form shown in Fig. 1, a setting member 13 acts through a link 12 and floating link 11 to vary the position of a shutter 10 between nozzles 9, to vary the action of fluid on a diaphragm 5, acted on by a spring 8. The position of a weir 2 is thus varied to alter the quantity of liquid in a hydraulic coupling 1; as the speed of a driven member 7 is altered, a governor 15 driven thereby acts through a lever 14 on the link 11 to return the weir towards its initial position. In a modification, the lever 11 is connected to the weir by linkwork, and the lever 14 is operated by a movable bell acted on by the delivery pressure of a driven blower. In a further form, the driven member is coupled to a generator 24, Fig. 3, which gives a voltage proportional to its speed, and energises repelling coils 25 one of which is mounted on the lever 14. The link 11 adjusts a resistance 27 in circuit with coils 28, one of which is mounted on a contact arm 29, which through contacts 30 and relays 33 controls a motor 31 which actuates the weir through reduction gearing 32, and also moves the contacts 30 to break the circuit. In another form, the delivery pressure from the coupling acts through a Bourdon tube 36, Fig. 4, and the mechanism controls inlet and outlet valves 34, 35.

As shown the stool having a screwed spindle 3 is provided with a nut 6 which when the stool is unloaded is pressed upwardly by the helical spring 5 so that it is frictionally held against rotation by the cap 4 of the column 1 and consequently permits adjustment of the stool on rotation of the spindle 3. A conical slit ring 7 is provided in the spindle 3 as shown which is, when the stool is loaded, forced into a conical recess in the nut 6 and so indirectly clamps the nut 6 to the spindle while permitting vertical resilience to the stool by means of the spring 5. In another form the ring 7 is omitted and the lower part of the nut 6 is slit and tapered which part is forced into the upper end of the spring to clamp the nut to the spindle when the stool is loaded.
