Abstract: In spiral scanning apparatus for bubble chamber photographs, comprising an elongated plane mirror which is lengthwise inclined upwardly and outwardly to an axis about which it rotates, to reflect toward the axis light shone downwardly onto it, and a periscope which rotates to have its eye face the mirror and simultaneously moves axially to scan along it, superimposed slotted fixed and movable mask means in front of the periscope eye enable sensitivity and selectivity to be adjusted for different photographs.

Abstract: 1,212,705. Propulsion jet deflection by blown flaps. SAAB A.B. 28 Nov., 1967 [29 Nov., 1966], No. 54071/67. Heading B7G. [Also in Division F2] An aircraft wing 2 comprises a trailing edge flap 9 pivotable about an axis 13 below the wing from a first position A where it forms a smooth continuation of the wing to a second position D where it forms an acute angle with the undersurface of the wing, a slot 21 between the forward edge of the flap and the main body of the wing, a gas turbine engine 5 mounted on the wing forward of the flap and the slot, a lower flap 23 movable (e.g. about axis 23) in dependence on the movement of the flap 9 (e.g. via a link 24 between a first position where it closes the slot to a second position corresponding to position D of the flap 9 where exhaust air flow from the engine 5 is deflected upwardly through the slot, an upper flap 25 movable from a position A where it forms a smooth continuation of the wing contour, and a position D at an acute angle with the upper surface of the wing, and control means 18 to co-ordinate the flap movements. The above arrangement may comprise the inboard halves of the wings, the outboard halves comprising further trailing edge flaps 7, upper flaps 8 and also leading edge flaps 6 which when extended provide further slots 6a and 6b through the wing. These flaps together with the undercarriage 30 may have their movements also controlled by the pilot's control means 18. All flap and undercarriage movement may be provided by hydraulic actuators 16, 26, 31, 32, 33 and 34. The lower end of the forward wall of the passage 21 may be rounded, and the flap 23 may itself be slotted. When the trailing edge flaps 7, 9, lower flaps 23 and leading edge flaps 6 are moved to the positions B, the left of the wing is increased due to increased camber and boundary layer control provided by air passing through the slots 6a, 6b, 12 and 21.

Abstract: The present disclosure relates to an antenna array including an integral antenna element structure mounted on a substrate. The integral antenna element structure includes a first set of antenna elements and a second set of antenna elements. Each antenna element including a first body and an adjacent second body. The second body is branched into a first leg and a second leg, wherein a transition pin forms an integral part with said first leg. The first set, and second sets of antenna elements are arranged such that the first body and the second body of each adjacent antenna element form a common tapered structure.

Abstract: A method for excitation of an array antenna across a specified bandwidth is disclosed. The specified bandwidth comprises M sample points, M being a positive integer >1, and the array antenna comprises N antenna elements, N being a positive integer ≥2. The method comprises forming a first matrix B(ω) defining an allowed frequency variation for an excitation coefficient for each antenna element, and forming a second matrix defining far field data for each antenna element at each sample point. Further the method comprises optimizing each excitation coefficient based on the formed first matrix and the formed second matrix, and controlling an excitation of the N antenna elements based on the optimized excitation coefficients. Hereby presenting a method for wideband optimization of the excitation coefficients for an array antenna.

Abstract: An antenna arrangement (1) comprising an antenna array is disclosed. The antenna array comprises N antenna elements (2) (N being an integer ≥3). Moreover, each antenna element is connected to an electronics module (3) out of P electronics modules, P being an integer such that 3≤P≤N, where each electronics module is configured to generate an output signal indicative of a signal received by a corresponding one or more antenna elements. The antenna arrangement further comprises control circuitry (10) connected to the antenna array. The control circuitry is configured to receive each output signal, compute a sum of cross-correlations between each output signal and a set of other output signals originating from other corresponding antenna elements, and determine at least one angle of a direction of arrival of the electromagnetic waves relative to the antenna array based on the computed sum.
