Title: Device for use in arresting aircraft
IPC: B64F1/02
Filed: 1972-11-22
Abstract: 1369526 Aircraft arresting gear ALL AMERICAN INDUSTRIES Inc 22 Nov 1972 [23 Nov 1971] 54018/72 Heading B7G [Also in Division E2] A cross-runway pendant 12 for an aircraft arresting gear is disengageably held at an arresting height above a runway 14 by a plurality of spaced tong assemblies 24 that are upwardly biased by resilient supports 42 installed in cavities 43 in the runway. Each tong assembly comprises a pair of jaws 26 made of an elastomer having sufficient resilience to hold pendant 12 and yet release it when snatched by an aircraft hook 28, the jaws 26 being carried by arms 44, 46 carried on opposite sides of cavity 43 by hinges 48 and interconnected by a pivot 80 to a fork 88 on the end of piston rod 76 extending from support 42. In the support 42 a piston 92 is formed with one-way metering valves 94 and urged upwardly by a spring 96 so that the pendant is urged into the aircraft-arresting position shown in Fig. 4. To enable aircraft to move freely over the runway a valve 100 is actuated to admit compressed air from line 104 through line 102 to space 93 to force piston 92 and the tong assembly down with the pendant supported just below the runway surface which for this purpose is provided with grooved blocks 30 of elastomer to damp wave motion of pendant 12 when it is bounced by an over-running aircraft. The spring 96 may surround support 42 (Figs. 8, 9, not shown) or it may be dispersed with, the necessary resilience being provided by making the tong support arms of resilient material (Figs. 13-15, not shown). In this embodiment metering valves 94 are dispensed with and energy-absorption is provided by low density plastics foam having an embedded spring positioned beneath the piston. In a still further embodiment (Figs. 16-18, not shown) the tong assembly is mounted on spring arms which are retracted by cables operated by an actuator mounted horizontally in the base of the cavity 43.

Filed: 1973-11-23
Abstract: 1501613 Releasing cables from vessels HUMBER ST ANDREWS ENG CO Ltd J MILLS and J MILLS [trading as BELL ELECTRONICS] 21 Feb 1975 [23 Nov 1973] 54507/73 Heading B7V [Also in Division G3] In a method of releasing a cable secured to a vessel, e.g. a tug, an electrical signal whose magnitude varies as a function of the angle of heel of the vessel is produced and the signal is used to actuate, e.g. an hydraulic jack to release the cable when the heel has exceeded a preset angle for a predetermined period of time. The system comprises an analogue power supply 2 and a sensor supply regulator 4. Output signals from the regulator 4 supply an angle sensor 6, e.g. a pendulum potentiometer connected to a meter display 12, via a damping circuit 8, which delays the signal from the device 6. A test control circuit is connected between the devices 8 and 12. The outputs from the supply regulator are also connected to a set trip angle control amplifier 14, and a set alarm angle control amplifier 16, each of which respectively supply a trip amplifier 26 and an alarm amplifier 35, via positive and negative angle comparators 18, 20, or 30, 32, and OR. gates 24 or 34. The device 26 supplies a solenoid valve 28 to control fluid flow from a reservoir 44 to a cable release jack 40 and the device 35 controls an audible alarm in advance of the jack being actuated. Amplifier 16 can be supplied directly from amplifier 14.
