Title: Improvements in and relating to breech mechanisms for automatic firearms
IPC: F41A3/40
Filed: 1958-02-03
Abstract: 879,948. Automatic firearms. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. Feb. 3, 1958 [Feb. 7, 1957], No. 3451/58. Class 92. A breech mechanism for an automatic firearm has a casing 10 with an inclined abutment face 10a in which is a movable, two-part breech block comprising a head 2 which takes the cartridge thrust and a rear part 4 which engages the head 2 abuts a recoil spring 6 and has an inclined abutment face 4a from which a tongue 9 extends towards the head 2. The head 2 moves due to reaction from a fired cartridge 11 successively from an inertia-locked position (Fig. 2), to an intermediate, positively-locked positive (Fig. 3) and thence to a recoiled position (Fig. 4). As the head 2 recoils the prismatic rearfaces of locking flaps 8 first engage both the abutment faces 10a and 4a thereby accelerating the rear part 4 relative to the head 2; further inward movement of the flaps 8 is then prevented by contact with the flat walls 4b of the tongue 9, so that the rearward flap-faces continue to abut the faces 10a and positively lock the breech head 2 until the part 4 moves further back to withdraw the tongue 9 from between the flaps (Fig. 3). The flaps then complete their inward movement and permit the head 2 to continue its recoil, pulled back by a lug 4c on the part 4. A firing pin 5 is pivoted on a pin 14 so that its tip falls out of alignment with the firing-hole in the head 2 when the parts 2 and 4 are separated. The head carries an extractor 3 which engages the rim of the cartridge. Prismatic locking blocks, sliding longitudinally and transversely (Fig. 5, not shown), may take the place of the hinged locking prisms 8.

Title: Improvements in radio antenna systems
IPC: H01Q5/00
Filed: 1946-02-05
Abstract: 634,845. Aerials. PHILCO RADIO & TELEVISION CORPORATION. Feb. 5, 1946, No. 3614. Convention date, July 22, 1944. [Class 40 (vii)] An antenna structure comprises a plurality of antenna arrays stacked linearly, each array comprising a coaxial resonator having antenna elements coupled therein, and a feeder system having individual feeders which are concentrically disposed with one feeder inside the other, the coaxial resonators being fed so that the feed point of one of two adjacent arrays'is remote from that of the other and the resonators being shortcircuited at their remote ends. Interference between the arrays and the feeder systems is prevented in such a structure which may comprise two arrays of elements 12 and 13, mounted on a hollow conductive mast 11. The lower half of the mast contains a centrally mounted hollow conductor 17 which co-operates with the inside of the mast 11 to form a resonant chamber 21 closed at its upper end by metallic insert 22; the radiators are coupled to this chamber by insulated probes 14 extending through the mast 11 and the extent to which the probes project determines the input impedance of the array. A coaxial stub of similar elements 25 and 27 with an adjustable plug 32 is used to match the chamber 21 to a feeder which may be connected at 15. Hollow conductor 17 contains a central conductor 44 which is flared out to form a concentric tube within mast 11 above insert 22. Tube 17 is also flared out and joins mast 11 at this point so that the concentric line feeder 17, 44 is terminated by a resonant chamber 43, closed by cap 41, to which radiators 13 of the second array are coupled by probes in the same manner as in the lower array. Central conductor 44 branches at 52 and conductor 53 continues along stub 25, 27 inside conductor 27 to coupling 54. Shield 25 is extended as shown so that the outer conductor of a coaxial feeder may be connected to conductor 27 without loss. A matching stub 63 for the upper array is formed inside the bottom end of conductor 17 and is tuned by metallic shorting bar 64. Solid dielectric spacers, half a wavelength long to prevent impedance mismatches, are used in the coaxial line 44-17. The Specification as open to inspection under Sect. 91 describes also a single array comprising elements coupled to a resonant chamber formed between two coaxial tubes. The array is fed centrally by forming a break in the inner tube and providing a central conductor within the lower half thereof and attached to the upper part, the central conductor and inside of the inner tube being the feeder. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to radio glide path landing systems for aircraft
IPC: G01S1/02
Filed: 1943-03-05
Abstract: 580,640. Directive radio signalling. STANDARD TELEPHONES & CABLES, Ltd., and WILLOUGHBY, E. O. March 5, 1943, No. 3663. Drawings to Specification. [Class 40 (v)] A glide path of the overlapping-field type comprises two antenna systems spaced apart in the direction of the glide path, the patterns of the two systems being so adjusted that the glide path becomes horizontal at a point in front of (as regards a landing craft) the forward antenna. The antennµ may be above ground, the forward one being off-set from the runway, the lobe of the forward antenna having a field decreasing with the glide angle and the lobe of the rear antenna may have a field increasing as the glide angle decreases. If both antennµ are flush with the ground level, the lobe of the rear antenna may decrease with decreasing glide angle, and the forward antenna may have a field increasing with decreasing glide angle. The antenna may consist of a slotted rectangular wave guide placed parallel with the runway, excited by an antenna at one end, or by a number of antennµ at different points along the guide so as to keep the power radiated from each slot equal. The slots may increase in size as their distances from the exciting antenna increase. Several guides may be placed end to end along the runway.

Abstract: 1,026,547. Aerials; pulse radar. NORTH AMERICAN AVIATION Inc. Jan. 29, 1964, No. 3875/64. Headings H4A and H4D. [Also in Division H1] In a radar, Figs. 1, 2, utilizing a reflector 10 illuminated by waveguide "turn-arounds" 20 the waveguides 16 and the turn-arounds conduct energy only in the TE 01  mode at the radar wavelength #. The arrangement forms part of a monopulse radar and the invention is stated to permit the turn-arounds to be curved or twisted so that their apertures may be placed at any desired orientation and/or position relative to the focus of the reflector, thereby producing simultaneous radiation patterns which may be relatively unsymmetrical or skewed. In an embodiment the input waveguide 14 (connected to the radar transmitter) is a little more than #/2 high and less than #/2 wide, thus supporting only the TE 01  mode. A dividing vertical septum 18, Figs. 3 and 6 is introduced and the waveguide height is increased in regions 19, 22 to produce two waveguides 44, 46, each being of height # and of width less than #/4, thereby supporting TE 01  and TE 02  modes in region 22. A horizontal septum 24, Fig. 1, divides waveguides 44, 46 into waveguides 34, 36, 38, 40, Fig. 5a, which support the TE 01  mode only, the apertures of the turnarounds being depicted by 26a, 28a, 30a, 32a. To afford any desired polarization and radiation patterns the turn-arounds may be curved and twisted, Figs. 5b, 5c, 5d, 5e. The echo energy is combined at waveguide 14, Fig. 1, for range measurement via a duplexer, Fig. 7 (not shown). For measuring target elevation error from the bore-sight an H-plane hybrid Tee 42, Fig. 6, is provided and for measuring target azimuth error from the bore-sight an E-plane hybrid Tee 60, Fig. 3, is added; an explanation of their operation is given, Figs. 8, 9 and 10.

Title: Improvements in power plant comprising a prime mover and an internal combustion compressor supplying motive fluid thereto
Filed: 1944-03-02
Abstract: 598,892. Servomotors. ENGLISH ELECTRIC CO., Ltd., and WELSH, R. J. March 2, 1944, No. 3904. [Class 135] [Also in Groups XXVI and XXVII] Power plant having a prime mover, such as a turbine 18, supplied with motive fluid from an internal-combustion engine-driven compressor, preferably of the floating piston type 1, has means responsive to the pressure of the motive fluid adapted to regulate the output of the gas generator to maintain the pressure in the manifold 17 constant during predetermined loading conditions for the prime mover 18. An orifice 20 allows restricted communication between the manifold 17 and a cylinder 19. Increase in pressure in 17, and thus 19, acts on a piston 22 to cause a fuel rack 10a to decrease the supply to the generator cylinder. A number of generators may be coupled up to the turbine, having motive fluid supply pipes 44, and fuel control links 45. A leak-off valve 21 may be moved by hand, e.g. by the operator of a vehicle driven by the prime mover. The piston 22 may act through another servomotor system on the link 29. The servomotor piston may vary the fuel supply while means responsive to the stroke of the free pistons vary the volumetric efficiency of the compressor, e.g. by actuating a throttle valve at the inlet 14 to the compressor as described in Specification 586,989, [Group XXVI]. Alternatively, the motion of the inlet throttle and of the fuel rack may bE co-ordinated as described in Specification 598, 530, [Group XXVI]. The piston 22 may control the output of the gas generator otherwise than act ing on the fuel rack. Ir Fig. 2, the position of the valve 21 is controlled by a speed governor 31 through a spring 38 and a rocking lever 39. On a decrease in speed of the turbine 18, the governor moves a valve 33 to apply pressure to a piston 36, which increases the opening of the valve 21 to lower the pressure in 19. The spring 23 accordingly moves the piston 22 to cause an increase in the fuel supply 10a, until the pressure in 17 is increased and the speed of the turbine has increased. The opening movement of valve 21 will have decreased the force exerted by the governor loading spring 38 so that the speed at which equilibrium is restored is slightly less than the previous steady speed. In Fig. 3, the lever 39 moves about a pivot 40 by a piston 41 under pressure of the fluid in the conduit 17, to decrease the loading on the spring 38 with an increase in pressure of the fluid. The engine may operate on the twostroke, compression-ignition principle.
