Title: Distance determination using secondary surveillance radar

Filed: 1975-06-16
Abstract: 1506186 Radio navigation LITCHSTREET CO 16 June 1975 [7 Aug 1974] 25611/75 Heading H4D In an additional use of the signals provided by the system described in Specification 1,407,091 the distance D of the own transponder 72, Fig. 2, from the SSR station 71 is calculated using the equation where A is the angle between the lines of position with respect to the SSR of the own transponder 72 and the other transponder 73, and Z is the distance between the own transponder 72 and a point on the other transponder's position line 71-73 at a distance D from the SSR. The signals provided by the own transponder circuit of Fig. 3 and used for the derivation of the equation are (a) The signals indicating the reception of the SSR north reference pulses, and a signal N representing the interval between such successive signals and thus the rotational period of the SSR beam scan. (b) The transponder replies from the other transponder within a specified range/azimuth box. (c) The differential distance X of the two transponders from the SSR. (d) The slant range Y between the transponders. In the additional circuitry of Fig. 8 the several successive transponder replies (b) are fed to an envelope detector 150 to produce a signal which stops a timer 152 which has been started by the previous N signal (line 154). This gives an interval signal L indicating the time the beam takes to sweep from North to the other transponder. Using the interval signal L and the rotational period signal N a divider 156 produces a signal L/N which is converted to the angle #<SP>1</SP> by a X360 degree function generator 160. #<SP>1</SP> is the bearing of the other transponder from the SSR with respect to north. The angle A is then determined at 164 from the numerical difference between #<SP>1</SP> and # the bearing of the own transponder. The X and Y signals are squared, summed and square-rooted at 170, 172, 174, 176 to give z=#X<SP>2</SP> + Y<SP>2</SP>, which Z signal is directed at 168 by a Sin A signal from function generator 166, to give D. The value of D may determine the mode of operation of the system as described in Specification 1,462,831.

Abstract: 650,539. Folding and finishing edges of sheet material. NATIONAL AUTOMOTIVE FIBRES, Inc. Sept. 22, 1947, No. 25757. Convention date, Sept. 23, 1946. [Class 42 (i)] [Also in Groups X and XVI] Trim panels comprising a body of compressed bonded fibres and a fabric cover M on one or both sides are formed with a marginal bead round which the fabric extends. The fibre layer with the fabric on top is laid upon a die member G and extends over an annular bed-plate F of inner contour corresponding to that of the panel to be formed. A lower die member H with its bottom part H<SP>1</SP> yieldingly supporting member G on springs I extends between member G and the bed-plate. An upper die J secured to a ram C and an annular member J<SP>3</SP> carrying trimming blades K first descend, a lower ram D then being raised to cause die members G, H to rise by means of pins and thus release the border portion of the blank whereupon springs I raise die G to the position shown in Fig. 6, the edge portion of the blank being bent downwards. Further movement of the ram D causes member H to force the edge of the panel into a cavity in the upper die to form a bead in which owing to the greater compression the fibres are more densely compacted. While the rams are in this position steam or other heating fluid traverses passages in members O, P adjacent to the dies to cure the blank. The panel is removed laterally after member J<SP>3</SP> has been lowered, a slight independent movement being permitted by shoulder bolts J<SP>5</SP>. The body material may comprise sisal fibres impregnated with thermosetting synthetic resin.
