Abstract: 958,713. Parachutes. G. Q. PARACHUTE CO. Ltd. Feb. 12, 1963 [March 2, 1962], No. 8268/62. Heading B7G. A parachute comprises a canopy and a number of rigging lines connecting the canopy to a parachutist, the canopy having two diametrically opposed openings which extend from the peripheral hem of the canopy to a point between the hem and the apex of the canopy and means whereby the parachutist can vary the relative sizes or shapes of the openings or areas while the parachute is in flight. As shown in Fig. 5, openings 20 are formed by leaving adjacent gores unconnected between a point 16 and the periphery of the canopy. These gores may be laced together to allow the point 16 to be moved. The gap in the periphery across each opening may be bridged by a piece of webbing. In Fig. 6, openings are formed by using gores 21 which do not extend to the periphery, and in Fig. 7, adjacent gores 23 are cut away to form triangular openings. These openings may be covered by netting of greater porosity than the material of which the gores are made. The size and shape of the openings may be varied by the rigging lines 13‹, to cause the parachute to drift or rotate, or by a separate control line 24-13‹ (Fig. 8), secured to one corner of a gore and passing through ring 25 attached to a corner of the adjacent gore. The parachute may be given an inherent drift by omitting a portion 26 of one of the gores (Fig. 5).

Abstract: 1,167,292. Monitoring I.C. engines. H.J. FREMONT. Feb.23, 1968, No.8974/68. Heading G1N. [Also in Division H3] The operating conditions of an I.C. engine are monitored by obtaining a train of pulses representing the variations of pressure in the intake and/or exhaust manifold and comparing it with a synchronous reference pulse train derived from the ignition system representing ideal operating conditions. As shown Fig.1, D.C. pressure signals derived from e.g. a diaphragm attached to the case of an LDVT unit then rectified, are fed via terminals 10, 12 to a mixer stage 14, and the amplified signals sent to a comparison circuit 18. A synchronous reference train of pulses is derived by a capacative pick-up 44 Fig.3 (not shown) attached to one of the spark plug terminals. Each ignition pulse Fig.2a fires a unijunction transistor 59 for a duration determined by capacitor 60 and variable resistor 63, to produce a rectangular pulse Fig.2b which is differentiated, and the negative pulses suppressed by diode 57 Fig.2c. The pulses are then fed to a second unijunction transistor 71 whose firing duration is determined by variable resistor 74, and the resulting rectangular pulses Fig.2d differentiated to produce negative and positive pulses Fig.2e which are fed via amplifier 80 to comparison circuit 18. The timing and amplitude of the reference train of pulses is adjusted so that when the apparatus is applied to a properly operating engine, the two trains of pulses reaching comparison circuit 18 coincide in time and are equal and opposite in amplitude, except for the large pulses derived from the spark plug to which pick-up 44 is connected. The output from circuit 18 is fed to an integrating circuit 100, 102, 104 adjusted at 102 so that the output from circuit 18 is due to the large pulses only biases transistor 94 so that it does not conduct. When applied to a test engine, if there is any other difference between the two pulse trains, the voltage across capacitor 104 is increased, causing transistor 94 to conduct, energizing relay 96 and operating an alarm 98. The output from transistor 37 may be shown on a CRO for visual examination.
