Title: Read-out instrument for an aircraft collis2on avoidance system
IPC: G01S11/02
Filed: 1970-12-31
Abstract: 1334680 Radio navigation McDONNELL DOUGLAS CORP 31 Dec 1970 [6 March 1970] 62076/70 Heading H4D An aircraft instrument for indicating whether a pilot of a first aircraft should climb, dive or level off to avoid collision with any second aircraft also has means for indicating rate of altitude change with respect to a reference plane or one or more of said second aircraft and means for indicating maximum safe rate of altitude change to avoid flying on to a collision course with other second aircraft at different altitudes. The cockpit indicator described in U.S.A. Specification 3,341,812 which indicates to a pilot on a collision course whether to climb, dive or level off is included in a rate of climb (ROC) meter and indication of maximum allowable ROC is also provided. On circular dials the maximum ROC indicator may be continuous or spaced lighted bands or moving pointers on the periphery or normal radial pointers (Figs. 1-6, not shown). An alternative embodiment has two linear scales with movable pointers for climb and dive (Fig. 7, not shown). Indicator drive circuitry, Fig. 9.-Comparator 154 provides a pulse at a time which represents the altitude of the aircraft carrying the apparatus, by comparing the counter 156 output with the digital output of an altitude sensor. The comparator output triggers a pulse from generator 160 of a length equivalent to the "coaltitude" band representing the "possible collision" band of altitudes. A receiver provides a pulse on line 162 whose timing represents the altitude of another aircraft and this triggers a similar "co-altitude" pulse from generator 164. If the two "co-altitude" pulses overlap, gate 208 inhibits generator 176 and no maximum ROC indication is provided. However, if they do not overlap, the bi-stables 166, 168 are set to states determined by which altitude pulse occurs first. If from line 162, bistable 168 is set, if from generator 154 bi-stable 166 is set. The trailing edge of the first occurring "co-altitude pulse" triggers monostables 176- 182 to produce four consecutive pulses representing four altitude bands above and below the "co-altitude" band (Fig. 8, not shown). The monostables enable NAND gates 184-206 consecutively in pairs and the second occurring altitude pulse thus appears at the input to one of the three-input NAND gates enabled by bistables 166 or 168. If the other aircraft also represents a threat by virtue of its range and range rate, a pulse is produced which triggers the light control representing the band containing the difference in altitude between the two aircraft and also all the higher value bands.

Abstract: 804,866. Electrolytic capacitors. GENERAL ELECTRIC CO. April 13, 1956 [April 13, 1955], No. 11333/56. Drawings to Specification. Class 37. The electrolyte for an electrolytic capacitor having aluminium electrodes comprises an aqueous solution of ammonium borate or succinate to which a small quantity of a silicate has been added. The electrolyte preferably also contains ethylene glycol or alternatively glycerine. The preferred silicates are sodium metasilicate and tetraethylorthosilicate. Formamide is also included in one example. It is stated that the simultaneous presence of the silicate and the ammonium compound prevents the hydration of the oxide film which serves as the dielectric on the aluminium cathode; the hydrated oxide is somewhat soluble and is a poor dielectric and by preventing its formation the shelf life of the capacitor at elevated temperatures is considerably increased.

Abstract: An annular end cap common to the coaxial inner 12 and outer 10 tubes of a shock absorber comprises two separate coaxial sheet metal sleeves 20, 22. One of these 22 is a spacer sleeve which has an annular upper edge 50 for centring in the upper end of the outer tube 10 and for axial abutment against an annular shoulder 62 of the outer tube, and a cylindrical lower end part 44. The other sleeve 20, is a bush-carrier sleeve which has, adjacent its lower end, an outer radial collar 24 held between the lower end of the spacer sleeve 22 and the upper end of the inner tube 12. A tubular part 32 of the sleeve 20, situated within the spacer sleeve, constitutes a cylindrical seat in which there is retained a bush 42 of a material having a low coefficient of friction in which the shock absorber rod 16 slides. This tubular part has a fixing section 34 which is situated immediately adjacent the collar and fixingly fits into and is centred in the lower end part of the spacer sleeve 22, and a projecting section 36 which extends with circumferential clearance within the spacer sleeve 22, from the fixing section to a free upper end of the tubular part 32 itself. The bush- carrier sleeve further comprises a cylindrical peripheral skirt 30 which is situated in the interspace between the two tubes of the shock absorber and in which there is housed and centred the upper end of the inner tube 12. This arrangement allows the bush 42 to yield on bending deformations of the piston rod. <IMAGE>
