Ornithopters; propelling; land wheels and skid.s.-The main spars of a Rapping wing machine are assisted on the downstroke by the resilience of twisted skeins of silk hemp, steel bands or other tensile substance. The main wing spars d are connected by cords to ausiliaxy spars c and both main and auxiliary spars are passed through crossed tubes s at the centres of the twisted skeins which are secured to the framework by similar cross-heads q and tensioning bolts. The inner ends of the spars d are connected to vertical rods f guided by pivoted links g. Crossed members h pivoted to one another at j and to the rods f at j are guided at their lower ends by rollers, k engaging the rods f. The pivots j support a saddle for the pilot who grasps hand rails m on the rods f, shoulder straps, not shown, also being connected to the rods m. The main spars are strengthened at their pivots by sheaths. The downstroke of the wings is effected by the pilot pressing his feet against a platform l on the main frame, and the upstroke is effected by allowing his weight to come on the saddle. Small wheels are carried on levers 111 which engage hooks o on the rods f as the machine alights in order to raise the wings. Main landing wheels p and a tail skid are provided. Specification 209,807 is referred to. The Provisional Specification describes a wing spar acted upon by a single twisted skein.

Filed: 1960-05-16
Abstract: 916,347. Directive radio systems. ALFORD, A. May 16, 1960, No. 17272/60. Class 40 (7). The invention relates to a directive aerial system adjustable to receive or transmit signals in any direction over a predetermined angular range (which may be 360 degrees) and which may be arranged to handle a plurality of signals simultaneously and independently. The system comprises a plurality of radiating elements spaced along a curve and backed by a reflector, each element having its individual isolating means which passes signals to or from combining means by which utilization apparatus may be coupled to a selected group of radiating elements. In one embodiment, thirty-six elements R1-R36 are arranged round a circle, each comprising a unipole mounted over its own radial network of wires forming a ground plane. Behind the unipoles is a cylindrical reflector 13 which may consist of a curtain of parallel wires. Each element is coupling to an isolation amplifier A1-A36 and the individual isolation amplifiers are selectably coupled to one or more combining means 21-28 associated with utilization apparatus. The combining means may introduce varying amounts of relative phase shift and attenuation in the lines from its associated amplifiers. Capacitive switching devices may be provided to select the connections from isolators to combining means and Fig. 5 shows such a device capable of introducing suitable phase shifts and attenuation factors for each element. The rotatable part of the switch comprises a pair of symmetrically arranged radial transmission lines 45, 46 with tangentially arranged ends pointing towards each other. The lines, which may be parallel plate lines, are capacitively coupled to a sequence of stator plates and dimensioned to provide appropriate phase delays and attenuations in the signal paths.

Abstract: 735,311. Insulating and securing of dynamoelectric machine coils. METROPOLITANVICKERS ELECTRICAL CO., Ltd. July 8, 1953 [July 9, 1952], No. 17336/52. Class 35. Rigid flat sheets 3 of self-supporting non- vitreous insulating material located between the preformed salient pole field coils 2 and the salient pole shanks 1 of a dynamo electric machine form the electrical insulation between such coils and shanks. The coils may be of the rectangular shape shown and may be joined at the corners as described in Specification 624,228, or may have flat sides and rounded ends clear of the pole shanks. The sheets may be subdivided at the sides of the coils into two or more sheets, and the adjacent edges of adjacent sheets may be spaced apart and the gaps therebetween may be filled by strips (not shown), of semi-soft material such as laminated glass fabric. Washers 7 through which the sheets 3 extend electrically insulate the top and bottom of each coil. Preferably the coils are made oversize and the sheets 3 are tightly secured by steel or other metal plates 8 disposed between the sheets 3 and the shank 1, which plates may have apertured lugs 10 bent into shank recesses 9 and by which the plates 8 may be withdrawn for dismantling. Between the plates may be flat and mounted angle strips 11, 12 of heat-resisting electricallyinsulating material such as glass fabric bonded with synthetic resin. At junctions in the sheets 3 the shank may be cut away, Fig. 1, not shown, to avoid electrical " creepage". To prevent damage to the sheets due to centrifugal force, 14 in the pole shoes 13 are filled with a soft material such as solder, and to prevent radial slackness of the sheets they may be clamped against a semi-soft material 16 such as woven glass which fills recesses in the body 15 of the rotor.

Abstract: 862,290. Optical alignment apparatus, ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 29, 1958 [May 31, 1957], No. 17409/57. Class 97(1) In order to determine the location of a body relative to a straight line, a line image of a source is formed by a diffraction grating, and this line image and a reference mark attached to the body are viewed through means attached to the body. As shown in Fig. 4, the body T to be located includes an eye-piece E and cross-hairs W which are mounted on a rod D, axially displaceable under the control of a vernier screw M. In front of the body are disposed a light source S and a diffraction grating G, whereby a line image of the source is formed along a line through the centre of the grating. The body T can be placed so that the cross-hairs W appear to lie on this line image, or the body T can be set in a known position and the rod D adjusted until the crosshairs coincide with the line image. A reflecting grating may alternatively be used, in which case the light source is carried by the rod D. As a light source a second diffraction grating may be employed, the spacing of which is the same as that of the grating G, and arranged so that the central point is opaque. The apparatus may be used for aligning bearing housings, as of a turbine.
