IPC: H01Q21/20
Filed: 1970-06-11
Abstract: 1284502 Aerials D M TRUSKANOV K R BRUNIN and L S RATNER 11 June 1970 28335/70 Heading H4A A transmitter aerial system comprises stacked tiers of radiator elements extending radially of the stack axis. Each tier includes n elements which are equi-spaced # degrees apart, and the elements of successive tiers are progressively offset from tier to tier by (#/4Œγ) degrees, where γ is a compensating angle. Means are provided for feeding the n elements of each tier in phase, and with the energizing currents of the tiers progressively differing in phase by 90 degrees from one tier to the next. In a first embodiment, of which the central portion only is shown in Fig. 1, seventeen tiers 2-18 of radial elements are mounted on a hollow cylindrical support 1 of diameter 1À17# 0  (# 0 =mid-band wavelength). The spacing between the centre tier 10 and either of the adjacent tiers 9, 11 is 0À75# 0 , and the spacing between any other two tiers is 0À45# 0 . Each tier has a main group of four radial radiator elements 19, which are spaced 90 degrees apart. In addition, the centre tier 10 alone has three other groups of elements 19, similar to the main group, and symmetrically disposed in relation thereto. The angle #/4 is 90/4 degrees, and the angle γ is zero for all main groups except those of tiers 2, 9, 10, 11, 18, where it is 4 degrees. The angular offset between the adjacent main groups of elements of tiers 2-3, 8-9, 11-12, 17-18 is 18À5 degrees, between those of tiers 9-10, 10-11 is 26À5 degrees, and between those of other pairs of tiers is 22À5 degrees. The main groups of elements in tiers 2, 6, 10, 14, 18 are fed at relative phase 0 degrees, those in the tiers 5, 9, 13, 17 at relative phase 90 degrees, those in the tiers 4, 8, 12, 16 at relative phase 180 degrees, and those in the tiers 3, 7, 11, 15 at relative phase 270 degrees. The three other groups of elements in the centre tier 10 are fed at relative phases 90, 180, 270 degrees respectively. The aerial system provides an omni-directional radiation pattern in azimuth, with control in elevation. It is stated that good matching to the feed-line is obtained over a wide range of frequencies. In a second embodiment (Fig. 3, not shown) there are four tiers each of which contains three radial elements arranged with 90 degree spacings in a 180 degree sector. There is an angular offset of 22À5 degrees between the groups of elements of adjacent tiers, and they are fed at relative phases of 0, 90, 180, 270 degrees, respectively. A directional radiation diagram is obtained covering approximately 180 degrees in azimuth. In a third embodiment (Fig. 4, not shown) there are eight tiers each of which contains two radial elements 180 degrees apart. The angular offset between the elements of adjacent tiers is 45 degrees, and there is a 90 degree increment of relative phase of the feed to successive tiers. In addition, each radial radiator element is provided with a radial passive reflector element. The radiation diagram is omni-directional in azimuth.

Abstract: 645,521. Heating glass by electric arcs and passage of current. CORNING GLASS WORKS. Nov. 3, 1948, No. 28555. Convention date, Jan. 9. [Class 39(iii)] A glass body is heated by disposing it between electrodes having a potential sufficient to form a discharge therebetween along its surface, but in which the arc is caused to strike through the body instead by the creation of a sub-atmospheric pressure at the head of each electrode. Glass articles may be united by applying a strip of readily dissipated electrically conductive material along an edge of one of the meeting surfaces, arranging the articles where they meet between the said electrodes and applying sufficient power to dissipate the strip in a manner heating the glass in the area to a more conductive temperature than adjoining regions and thereafter increasing the power input whilst the said sub-atmospheric pressure removes volatile foreign matter from the discharge area. The article may rotate between the electrodes and the sub-atmospheric pressure may be increased with increased electric power. According to one construction Fig. 1, each electrode has a central bore 20 coupled to a vacuum line and the electrode head is water cooled. Alternatively Fig. 3, each electrode contains a central tube 58 in a body 51 having a helical groove 52 around its periphery, the tube 58 and the groove 52 terminating at an opening 57 at the rear of the electrode.

Filed: 1937-10-20
Abstract: 493,399. Lubricating. NEMETZ, G. Oct. 20, 1937, No. 28576. Convention date. Oct. 21, 1936. [Class 12 (iii)] In a central lubricating system an oil distributing and apportioning device includes two pistons 1, 1a, reciprocable in bores 2, 2a, in a single casing 40. The bores are mutually perpendicular, are in different planes and partly intersect one another at the centre of the device. The pistons are recessed, as shown. Each bore is connected to two of four outlets 42 .. 42c. The central recesses 13, 14, 13a, 14a, of the pistons are connected by a duct 15, 15a, in each piston. Oil from a source of pressure enters the casing through a central port 6. Some passes through ducts 15, 3c, to chamber 100c, and holds the piston 1a in the position shown in Fig. 1. Oil also passes through ducts 15a, 3 to chamber 100 and acts on the piston 1 to move it axially so that oil already in the chamber 100b is ejected through outlet 42b, via ducts 3b, 7b. The piston la cannot move while the piston 1 is moving owing to the interlocking action between the pistons. After the piston 1 has finished its stroke oil is led to the chamber 100a and the piston 1a makes a stroke to the left to eject oil in the chamber 100c through outlet 42c via duct 3c, 7c. Subsequently the piston 1 makes its return stroke to eject oil through outlet 42 and then the piston 1a returns to eject oil through outlet 42a. The number of strokes made by the pistons is registered by a counter operated by the piston 1. The counter mechanism is completely closed in a sleeve 41 open to the chamber 160. The counter is driven from the piston 1 by a forked lever 32 and the counter readings can be observed through a window.

Filed: 1966-06-28
Abstract: 1,165,751. Gas filter mounting. VOKES Ltd. 19 June, 1967 [28 June, 1966], No. 28850/66. Heading BIT. [Also in Division E2] The peripheral frame of a pleated paper gas filter element 25 is urged upwards into sealing contact with gasket 32 on peripheral seating 28 within a gas duct by two bars 33, engaging the lower edge of the frame and 'mounted between respective pairs of end plates 40 which are pivoted at 44 and engaged by heads 39 of compression spring assemblies. Each spring 36 is permanently compressed in its tube 35, and when element 25 is engaging gasket 32 the springs act on plates 40 to urge the element upwards. When the element is lowered, by turning handles 45 from position a towards position b, the springs expand until heads 39 engage plates 41, (42), whereafter the springs no longer act on plates 40 though still under compression. The arrangement enables similar compressive forces to be applied to elements despite variations in their vertical heights, as such variations involve small alterations in compression of the springs 36 compared with their normal-compressoins. Access is provided, for changing filter elements, through door (29) (Fig. 2, now shown).
