Abstract: This device for automatically releasably hanging and holding against lateral oscillation load carried under aircrafts has load suspension hooks and holding members preventing the lateral oscillation of the load which project very moderately from the underface of a closed casing containing the actuating mechanism. This mechanism includes in combination linkage detents and springloaded devices disposed on either side of each load suspension hook. A certain delay is introduced into the action whereby when the load is lifted for engagement with the hooks, these are actuated to their load-supporting position and release with a predetermined time-lag the linkage holding the load against lateral oscillation to their operative position. To this end, each pivotally mounted hook is connected via a spring-loaded piston-and-cylinder actuator to a rocker controlling the movement of wedge members controlling in turn a lever supporting the holding members.

Abstract: 1514242 Compandor systems NORTHERN TELECOM Ltd 13 Aug 1975 [27 Aug 1974] 33749/75 Heading H4R Compressor or expander, for use in a compandor, has a number of variable gain circuits connected in series, isolated by buffer amplifiers, each variable gain circuit including a filter network to limit the variable gain characteristic of the circuit to a mutually exclusive operational band of frequencies and providing a substantially constant gain at other frequencies, with a separate control unit associated with each variable gain circuit to control the gain thereof, each control unit being responsive to signals of a frequency in the range corresponding to the operational band of the associated variable gain circuit. As described a compressor, Fig. 8, has a signal input at 2 applied via a transformer 60 in balanced form to the inputs of amplifiers 80 and 81 which feed via respective transistors 82 and 83, buffer amplifiers 88, and 89. The inputs of the buffer amplifiers 88 and 89 are bridged by a high pass filter network 21 c in parallel with an assembly of series diodes 12. The amplifiers 88 and 89 feed a second circuit identical to that described above except that the high pass filter network 21c is replaced by a low pass filter network 26c. The second circuit feeds the output port 3 via a transformer 62 from a tertiary winding of which is derived a control voltage to control the impedance of the two assemblies of diodes 12. The control voltage for the diodes 12 in the first circuit, or low band compressor, is fed via a low pass filter 41, a full wave rectifier 31, a time constant control circuit 32, 33, a voltage clamp 71, which limits the minimum impedance of the diodes 12, and a current source 35, 36, the output current from which flows, via the transistors 82, 83. through the diodes 12 to vary their impedance, and therefore the gain of the circuit at low frequencies. In a similar manner the control signal fed via the high pass filter 46 controls the gain of the high band compressor at high frequencies. In both circuits current sources 86, 87 and 90 are provided to supply sufficient current for amplifiers 80, 81, 82, 83, to handle large out of compression band signals without limiting while allowing only the control current to flow through diodes 12. The corresponding expander, Fig. 9, uses a similar circuit except that the filters 21c and 26c are connected in a negative feedback circuit for the amplifiers 100, 101, 102, 103, to provide an inverse form of control to that provided in the compressor. In the expander circuit transistors 96 and 97 act as current drains to draw current through the transistors 102 and 103 to prevent limiting at high out-of-band signal levels. A modified high pass filter to replace the filter 21c in Figs. 8 and 9, and which has a slightly increasing impedance at high frequencies, providing a better signal to noise ratio for the compandor system, is described with respect to Fig. 10 (not shown).

Abstract: An apparatus and method for monitoring stored material is disclosed. Material to be stored and monitored is placed within the innermost container of a series of nested containers and monitoring fluids are circulated in a closed loop of fluid flow through the spaces between the nested containers. Monitoring devices are used to analyze said monitoring fluids to detect leakage of the stored material from the innermost nested container and to detect the migration of external fluids into the series of nested containers. A computer based monitoring system continually checks the values of various parameters of the monitoring fluids to immediately detect and report the presence of stored material or external fluid in the monitoring fluids. The stored material may then be immediately retrieved from storage to repair leaks in the series of nested containers.
