Title: Improvements in or relating to directional electromagnetic wave antenna apparatus
IPC: H01Q13/02
Filed: 1941-12-06
Abstract: 581,763. Directive radio signalling. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Dec. 6, 1941, No. 15755. Convention date, Nov. 26, 1940. Addition to 581,762. [Class 40 (v)] . Relates to directional antenna arrangements using two slotted wave-guides at an angle, e.g. for producing a landing beam which is not symmetrical in its plane of maximum directivity, so that any desired gliding angle may be obtained on the lower part of its radiation pattern without reducing the field intensity in the upper part of the pattern to such an extent that it is difficult for a pilot to pick up the station. Means are also provided for increasing the directivity in a plane at right angles to the plane of maximum directivity. For producing an unsymmetrical radiation pattern, (1) the two guides 11, 12 may be excited unsymmetrically by arranging the dipole 13 oneeighth of a wave-length from their junction, or (2) the two guides may have a varying contour along their length, e.g. by varying the cross-section of the guide, thereby varying the velocity of propagation in the guide and therefore the directivity of the radiation, Figs. 4, 5, 6 and 9 (not shown), or (3) the dimensions of the slot through which the radiation passes may be varied along its length, Fig. 9 (not shown). For increasing the directivity of the beam in a plane at right angles to'the plane of the paper. the guides 11, 12 may be provided with semi-cylindrical reflectors 4, 4<1 >secured to the sides of the slots 5, 6.

Title: Improvements in or relating to the production of building tiles
IPC: C04B32/00
Filed: 1964-04-16
Abstract: Tiles are made by (1) forming a mix of, in per cent by weight, (a) ground feldspar, 5-50; (b) sodium carbonate or other substance having an analysis of more than 15% alkali metal oxide, 0.5-20; and (c) coarse-grained substance of m.p. not less than that of (a), 45-90; (2) mixing with water and shaping; (3) firing at 950-1200 DEG  C.; and (4) cooling stepwise.  The firing should proceed until an apparent porosity of not more than 14% results. Feldspar (a) should be an alkali metal oxide containing feldspar of the zeolite or rock glass type or other effusive volcanic glass, and should be ground finer than 100 a ; (b) may comprise, e.g., water-glass or silicofluorides of Na or K.  Other permissible additives include alumina, dolomite and materials containing alkali oxide or alkaline earth oxide.  (c) may be, e.g., chamotte, porcelain, basalt, granite, quartz sand or a mixture thereof, with particle size higher than 0.5 mm.  If silica is used, less than 3% of additives e.g. fluorite, aluminium fluoride, sodium fluoride or metal powders are preferably included to aid conversion of quartz to crystobalite or trimidite. Pigments may be added to an amount below 5% by weight, and may be ground together with substance (a).  This mixture may be applied to the surface of the shaped unfired tile by dry or wet sprinkling. Pigments include oxides of Co, Cr, Cu or Mn.  The tiles are formed by pressing and placed in a tunnel kiln on a horizontal surface dusted with a substance to prevent agglomeration with the carrier, e.g. quartz, bauxite, alumina, light ash or quartzite. The tiles may have a ribbed or coarse back, and may have a smooth or coarse surface, which may be fluorescent.

Abstract: 797,058. Stuffing-box substitutes. AKTIEBOLAGET GOTAVERKEN. May 23, 1956 [June 10, 1955], No. 16017/56. Class 122 (5). A stuffing box 9 for the piston-rod 10 of a reciprocating engine has a series of grooves for the reception of scraper rings 13, 18, 19 and is characterized in that the outermost of these grooves 11, 17 are in communication with separate drain passages 20, 22. An intermediate scraper ring groove 16 is in communication with a drain passage 23, separated from those of grooves 11 and 17 and packing rings 12, 15, are also provided. The drain passage 20 collects contaminated oil from the portion of the piston-rod working within the scavenge chamber 3, the drain passages 22 open direct to the crank case 7 to return clean oil scraped from the lower portion of the piston rod 10, and the drain passage 23 collects partly-contaminated oil from the intermediate groove 16, whence it is taken by a pipe 24 to an oil purifier. To obviate clogging of the rings, a supply of thin oil or solvent from a container 26 is fed to the uppermost groove 11 through a passage 25, the drain passage 20 from this groove being connected by a pipe 21 to an oil separator 29 having a drain 34. A three-way cock 28 allows the pipe 21 to be connected either to the oil separator or to a sludge tank. The oil separator 29 is connected by a pipe 32, through a non-return valve 31, to a chamber 33 between the suction and discharge valves of a scavenging air pump 4, the non-return valve being so arranged that contaminated oil may be sucked from the drain passage 20, and leakage of scavenging air to the crank-case may be reduced. The container 26 may be pressurized through a pipe 27 connected to the scavenging air chamber. Valves are provided to allow this pressure to be shut off during filling of the container, and the filler pipe to be shut off when the container is pressurized. In a modification, the two upper scraper ring grooves may be connected to the scavenging oil passage and drain passage.

Abstract: 1,211,453. Rotary flow meters. HALLIBURTON CO. April 5, 1968 [June 15, 1967], No. 16497/68 Heading F1F. [Also in Division H2] In a magnetic coupling, e.g. for a fluid-flow meter, drive is transmitted between coaxial shafts 96, 80 by permanent magnets 98, 86 carried by the shafts, the magnet 86 having limited rotation with respect to the shaft 80. As shown in Fig. 3, a fluid-flow meter comprises a two-part housing 10, 12 divided into chambers 24, 53 by a central partition 48, the chamber 24 containing a paddlewheel impeller 32 from which projects the shaft 96. The magnets, as shown, are cylindrical with two poles and are located on either side of a cupshaped, fluid tight partition 97 forming part of the partition 48. Shaft 80 drives a meter 15 in the chamber 53 and rotation of magnet 86 with respect to shaft 80 is confined to 180 degrees by a peg 94 which can abut either of two shoulders 92, under steady driving conditions, the peg 94 abuts one of the shoulders with opposite poles of the two magnets in registration. A sudden change in the fluid-flow will, however, disrupt the magnetic coupling due to the inertia of the meter so that the magnet 98 will either overtake or slow down relative to the magnet 86. Under these conditions, as the poles of the two magnets pass each other the magnet 86 will oscillate about shaft 80 and transmit a series of impulses to peg 94 to either accelerate or decelerate shaft 80 until the magnetic coupling can again lock into engagement. Instead of being concentric, the magnets may be arranged in line.
Patent GB-422678-A (GB)
Title: Improvements in the maturation of spiritous liquors
IPC: C12H1/00
Filed: 1934-06-04
Abstract: Spirituous liquors are matured by bringing them in the vapour phase into intimate contact with oxygen and a chemically inert distributing agent such as porous carbon, silica gel, and the like until the undesired ingredients such as acrolein and alkyl alcohol have been converted into harmless constituents by chemical reaction, and afterwards condensing the liquors.  Suitable forms of porous carbon include bone char, activated carbon made from coconut shells, and purified petroleum coke.  The agent is preferably employed in granular form.  The process may be combined with the distillation of a fermented mash containing the spirituous liquor to be treated, the treatment chamber being conveniently arranged between the still and the condenser.  The apparatus may be glass-lined or constructed of wood, stainless steel or a ceramic material.  The passage of oxygen may be either in the direction of flow of the vapour or in counter-current thereto.  The temperature at which the process is carried out depends on the amount of alcohol in the vapour treated, and the pressure may be atmospheric or higher or lower than atmospheric. The proper duration for the treatment is determined by taste and odour tests on the product, but is in all cases a few seconds or less.  A woody flavour may be imparted to the liquor by condensing it in the presence of, or treating it in the vapour phase with chips of or otherwise finely divided wood, such as hard white oak, either charred or uncharred.  Spirituous liquors which may be treated include whisky, brandy, rum, gin, liqueurs, and ethyl alcohol employed in the manufacture of alcoholic beverages.  Ethyl alcohol treated according to this invention may be mixed with extracts or blended with other distilled liquors.  An example is given.
