Title: Plate-form folded dipole antennae
IPC: H01Q9/06
Filed: 1976-05-11
Abstract: 1530703 Plate-form antenna FRANCE ARMED FORCES MINISTER OF 11 May 1976 [15 May 1975] 19443/76 Heading H4A A wide-band folded dipole antenna is defined by coplanar portions 1, 2, 4 and gaps 3, 9, and is fed by a line 8, one end of which is connected across gap 3. The antenna is backed by a spaced, parallel, planar reflector (not shown) and may be constructed by printed circuit techniques. In the embodiment shown the feed line 8 is of strip form and its connection to plate portion 2 is by way of a short, high impedance line 12. Plate portions 7, 4, 5, 1 act as the ground plane for strip-line 8. Plate portions 1 and 2 could be full rectangles (Figs. 2 and 4, not shown) but, as shown in Fig. 1, have their comers 14-17 cut away to modify the capacitance presented by gap 3 in parallel with the dipole radiation impedance. Shorting strips 10, 11, across gap 9 are suitably positioned for matching the impedance of the dipole to that of line 8. Alternatively, the matching is effected by two quarter-wave short-circuited strip-line stubs (36, 37, Fig. 4, not shown) extending from line 8.

In order to shorten the length of the take-off run of an aircraft provided with an annular wing which houses a propeller the transverse planes containing the leading and trailing edges are inclined obliquely to the longitudinal axis of the wing. In Fig. 2 the wing 2 has its leading edge 1 and trailing edge 8 so arranged that the airflow induced through the wing by a propeller H creates an area of negative pressure 3 which facilitates take-off. Further, the leading edge is provided round its upper periphery with a blowing slot 4 directed to the interior of the wing to accelerate the boundary flow over the upper leading edge and thereby move the area of depression aft. A further blowing slot 7 is provided over the lower portion of the interior of the duct some distance back from the leading edge. The boundary layer flow over the rear portion of the wing 2 is controlled by a blowing slot 10 and increased lift is obtained by downward deflection of the air flowing through the wing. This is achieved by flaps 11 mounted on or forming the trailing edge of the upper part of the wing and articulated flaps 14, 15 mounted at the midheight of the trailing edge 8. The flaps 11 may be hinged to nest against the inner wing surface when retracted or they may conform to the inner and outer profiles and be mounted for pivotal movement within wing cut-outs or they may be formed as part of the wing trailing edge to provide a slot when deflected. Flaps 14 and 15 are operated by linkwork and a jack to take up deflected positions in which flap 14 is given a small-positive incidence and flap 15 a large positive incidence about their common pivot. A fuselage 22 is housed centrally within the wing 2 and secured to it by wings 23, provided with control surfaces 34, and a fin 28 which extends aft of wing 2 to terminate in upper and lower rudders 31. Wings 23 have anhedral and are co-planar with further wings 24 which terminate in fairings 25 to form landing skids or to enclose landing wheels. It is stated that the propeller H could constitute the fan of a ducted-fan turbojet unit. Specification 745,630 is referred to.

Abstract: 1397512 Necking-in open can ends GULF & WESTERN INDUSTRIAL PRODUCTS CO 27 April 1973 [17 May 1972] 20260/73 Heading B3E A method of necking-in an open can end portion 16 using an apparatus A comprises gripping the inner 14 or outer 12 surface of a body B over a major portion of its circumference and over a substantial portion of its length with an expandible and contractable gripping device C, positioning a rotatably mounted female forming roller H having a circumferential arcuate groove 120 and a rotatable male forming roller I having a circumferential arcuate rib 162 receivable in the groove about the open end portion, and moving the rollers to form a smoothly curved inwardly directed circumferential bead in the end portion, the rollers H, I being so shaped and dimensioned as to produce an outwardly directed circumferential hump 250, Fig. 10. A mandrel C has a plurality of spaced axially extending slots 23 to define gripping members 34. A conical wedge portion E is positionable within a threaded bore 40 for expanding the members 34 outwardly from axis 42. The mandrel is rotatably mounted in a bearing D which is driven by a motor 28 via pulley 22. The rollers H, I are mounted on a structure G which includes a block member 56 which receives shafts 66, 68, Figs. 5, 6, having threaded ends 70, 72 threaded into blocks 78, 80. Bearing blocks 80 are rotatable with shafts 66, 68 about axes 90, 92. Respective shafts 102, 156 extend through blocks 78, 80 on which rollers H, I are mounted. Shafts 102, 156 are eccentrically mounted so that the axes of the rollers are offset from the shaft axes. Bearing block 80 is yieldably biased towards block 78. A block member 190 is secured to block 56 and receives a set screw 194 in a bore 192 which is adapted to adjust a coil spring 196. The force on the block 80 tends to rotate the block about axis 92 to move the roller I towards roller H. Levers 206, 208 are secured to shafts 102, 156 to enable the moving of the rollers to contact the open end of the body. The mounting block 56 is slidable on a base (220), Fig. 4 (not shown), for movement toward and away from the mandrel C. Bearing block 80 may be held in a predetermined spaced position relative to block 78 by the provision of a pin 144 and adjustable set screw 148. In operation, a can body B is mounted on mandrel C and members 34 are adjusted to grip the inner surface 14. Mounting block 56 is moved towards the mandrel to position the rollers on either side of the cam wall, a stop collar 126 being used to locate accurately the roller H with the open end portion. Motor 28 is energized to rotate the mandrel and can. As the roller H is moved towards the roller I an outwardly extending flange is formed. The roller I is then moved towards axis 42 of the can by rotating lever 208. Rib 162 of the roller I engages surface 12 of the can and moves into groove 120 of the roller H to reduce the diameter of the can at end portion 18.
