Title: Sidelobe suppressing antenna system comprising directional coupler and phase controlmeans for beam shaping
IPC: G01S13/76
Filed: 1964-07-29
Abstract: In an aerial system similar to that disclosed in the parent Specification a 180 degree phase shifter PS, Fig. 3, may be brought into circuit between the directional coupler K and the elements H by opening a bridging switch SW, whereby when the system is supplied at T2 the elements H radiate in phase with the element He, producing a resultant pattern as shown at P, Fig. 2. When the system is supplied at T1, with the switch SW open, the element He radiates in phase opposition with the elements H, causing a minor degradation of the highly directional pattern L (with side lobes S). When the switch SW is closed, the system is equivalent to the parent system and the same radiation patterns are produced (Fig. 1, not shown).

Title: Improvements relating to Systems and Methods for Radiation Level and Distribution Measurement
IPC: G21C17/10
Filed: 1967-09-07
Abstract: A device for transferring articles, e.g. balls 21, in discrete batches from a tubular input 6 to a tubular output 5 comprises a rotatable member 7 having radial tubular pockets 8, 9, 10, 11, 12, 13 into, and from which the batches of balls are moved under gas pressure when a pair of pockets are aligned with the input 6 and output 5, intermittent rotation of the member 7 placing succeeding pockets into alignment with the input and output. The intermittent motion is derived from a Geneva mechanism 17 secured to the member 7 which is rotatable in a housing 1. Passages 14, 15, 16 of reduced cross-section, connect radially opposed pairs of pockets to permit the passage of gas but not balls therethrough. In a modification, Fig. 3 (not shown), the rotatable member moves around a cylindrical core which is rotationally fixed and is provided with a gas passage to connect opposed pockets. This core is however axially displaceable to align a second passage in the core, with the opposed pockets, this second passage being of the same cross-section as the pockets to provide straight through passage for the balls when batching is not required.

Patent ES-353630-A1 (ES)
Title: Improvements in or relating to ceramics
IPC: C04B35/111
Filed: 1968-04-27
Abstract: Alumina in the form of a thin layer is produced by first forming an alumina slip by intimately mixing together a size graded alumina, i.e. an alumina having a broad particle size range, this alumina having a minimum surface area of 12 m2/gm, a solvent, i.e. a liquid preferably organic which is volatile at temperatures only slightly elevated above the ambient, a binder, i.e. a material which retains the alumina in its cast shape after the solvent has evaporated and which is soluble in the solvent, casting the mixture on to a surface to form a layer and removing the solvent to give an unfired layer. The layer may be fired to give a ceramic product. Preferably the alumina used has a maximum surface area of 16 m2/gm. and the layer is fired for a period of time ranging from 15 mins. to 3 hours at a temperature ranging from 1425- 1550 C. The sovlent may be eliminated from the prefired layer by drying for several hours at room temperature. A plasticizer which is compatible with the binder may be added to the mixture and an exemplified combination is a polyvinyl butyral resin and a plasticizer consisting of a mixture of glycol and a phthalate. The solvent may be an azeotropicmixture of two organic liquids one of which is soluble in water e.g. a mixture of ethyl alcohol and trichlorethylene. The mixture may also include a grain growth inhibitor, e.g. talc, and the alumina required for the composition may be obtained by taking an alumina having a surface area of less than 12 m2/gm. and milling it in the presence of at least a portion of the solvent and a deflocculating agent, e.g. menhaden oil. The surface on which the composition is cast may be cellulose acetate, glycol-terphthalic acid polyester, a fluo-halocarbon film, or chromium plated stainless steel. The dried prefired layer may be cut into the desired shape or shapes before firing and during such firing the shapes may be weighted down by previously fired shapes to prevent warping. The fired product preferably has a maximum grain size of about 1 micron, zero water content, and a Centre Line Average finish on at least one surface of less than 3À5 micro inches.

Title: Improved method for conveying semifluid material and apparatus therefor
IPC: F04B9/02
Filed: 1969-01-10
Abstract: In a concrete or other semi-fluid material pump concrete is drawn from a hopper 1 into an intermediate container 4 partially under gravity and partially by suction on the retraction of a piston 6 actuated by fluid, preferably water, pressure supplied and exhausted through an opening in the bottom of container 4. The concrete then passes into a cylinder 14 on the forward stroke of piston 6 as a piston 16 retracts by means of a belt 53 rotated around a reel 54 driven by a motor 58. A pipe 18 closed on the suction stroke of piston 16 by engagement with a fixed conical valve seat member 33, has a piston 22 and is moved under fluid-pressure acting through inlet and outlet pipes 25, 26 into sealing engagement, with cylinder 14, and the piston 16 actuated on its forward stroke by fluid-pressure acting through inlet and outlet pipes 65, 67 to force concrete past the fixed valve seat member 33 and into a discharge pipe 17 vibrated during this phase by a vibrator 40 to maintain a homogeneous mix of concrete. The pumping sequence and operation of fluid-pressure is controlled by switches 12 in the container and 64 on the drive belt of motor 38 to open and close quick acting valves in the fluid circuit at the appropriate time. The concrete temperature is maintained substantially constant during weather changes by means of a cooling jacket 2 around hopper 1. For facilating assembling and dismantling of components cylinder 14 is clamped with rods 74, Fig. 5 (not shown) between sealing sleeves (42) and (57) and a tie rod (75) retains the conical members 20, 21 in engagement. In further embodiments the piston 6 maybe a diaphragm and the piston 16 retracted by means of a hydraulically operated piston connected to traction band 53.
