Title: Improvements in radio direction finders
IPC: G01S1/02
Filed: 1951-11-08
Abstract: 738,812. Radio direction-finders. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Nov. 8, 1951 [Nov. 18, 1950], No. 26181/51. Class 40 (7). A radio direction-finder includes a rotating aerial system including two oppositely directed, sharply directional arrays 10 and 11 mutually separated by means of a reflector 12. The signals received by the arrays as the system is rotated by motor 16 through gearing 14, 15 are fed respectively to the orthogonally-arranged stator coils of goniometer 19. The rotor 22 of this goniometer is driven by motor 30 at a speed which may be the same as or different from the aerial rotation speed. Its electrical output is combined with the unmodulated signal from non-directional aerial 24 in receiver 23 ; the goniometer output effectively providing a bearing information modulated sideband to the aerial 24 signal. The receiver feeds a filter and demodulator 26, the output from which is fed to intensity control 32 of cathode-ray tube indicator 31 in order to brighten up the trace when signals are received and also to deflecting coil energization circuits 27 and 28. These circuits are shown in greater detail in Fig. 2 and comprise 4 triodes 34, 35, 36 and 37 to all the grids of which are fed the signals from demodulator 26. Sine and cosine reference signals from generator 29 driven at the same speed as the goniometer 19 are fed respectively in opposite phase to the cathodes of valves 34 and 36, and 35 and 37. The anodes of valves 34 and 35 are joined and fed through resistor 38. The anodes of valves 36 and 37 are similarly joined and fed through resistor 39 while the deflection coil 33 of the cathode-ray tube is connected between the two pairs of anodes. This coil is rotated round the tube in synchronism with the aerial rotation by a mechanical connection from motor 16. The display is brightened up on receipt of a signal by either aerial array and a portion of the tube screen 45 brightened as shown at 46 to indicate the incoming signal direction. Providing the goniometer rotation speed is adequate the indication will comprise a series of radial lines. The arrangement of Fig. 2 ensures that signals received on both arrays from the same bearing produce displays in the same direction radially of the tube despite the coil 33 having moved 180 degrees between reception on the two aerials.

Title: Improvements in or relating to protective systems for polyphase transmission lines
IPC: H02H1/00
Filed: 1948-10-08
Abstract: 652,191. Protective cut-out arrangements. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 8, 1948, No. 26281. Convention date, Nov. 29, 1947. [Class 38(v)] In a protective system for a three-phase transmission line, similar to that of Specification 651,998, the fault-detector relays FD1 and FD2 each have an operating coil (denoted by FD1 and FD2) and a restraining coil FD1R and FD2R. The operating coils are connected in series and supplied from a network of filter HC B over a non- saturating transformed NST and a rectifier bridge RB. The restraining coils are connected in series in the anode circuit of a triode 9, the grid of which is connected to a tapping on a resistance RO1 fed from the output terminals m, n, of a minimumvoltage network. This network gives at terminals m, n, the smallest of the three phase-to-phase voltages supplied by transformers Ta-Tc. The latter energize rectifier bridges Ba-Bc and condensers Ca-Cc, which are 'shunted by resistors Rr, the potential drops across the latter being applied to terminals m, n, through reverselyconnected rectifiers 6a, 6c. The relays FD1, FD2 thus serve as quasi-impedence relays, the former having a lower current-setting and higher impedance-response than FD2. As in the prior Specification, these relays respectively control the operation of valves V2, V2, and tripping relay R.

Filed: 1921-10-06
Abstract: 192,446. Sandberg, C. P. Oct. 6, 1921. Modifying physical characters of metals.-In order to avoid defects in railway and tramway rails caused. by internal stresses set up by unequal cooling after the rolling operation, a gentle cooling agent is directed on to the portions of the rail of heavier section in such a manner as to ensure that all parts of the rail shall arrive at and pass through the range of temperature 450-300‹ C. at the same time. The cooling agent may be applied after the rail has been allowed to cool naturally through the critical range, or the treatment may be applied as an improvement in the process described in Specification 18972/14, in which case baffle plates such as c may be used to cause the air from the pipe b directed on to the head of the rail subsequently to pass over the lighter portions. If necessary additional jets may be directed on to the underside of the rail head and junction of the web and flange in order to ensure equal distribution of heat within the range of temperature 450-300‹ C.

Abstract: 427,451. Indexing. BERGQUIST, N. O., H÷glandst÷rget, Alsten, Stockholm. Sept. 15, 1934, No. 26533. Convention date, Oct. 5, 1933. Drawings to Specification. [Class 16] A book, the pages of which display sections of a map, scheme, table, drawing, or other printed matter, the boundaries of such sections corresponding as regards position on the map &c. to segments of parallel lines drawn on the map &c. in directions perpendicular to each other, is characterized in that finger grips are provided at the edges of the pages by means of which all of the sections bordering on any individual section are immediately accessible from the section exposed, and each of them can be reached by a single grip. As applied to a map, an east-west or west-east route can be followed by simply turning over the leaves one by one, but a north-south or south-north route is followed by turning over a series of leaves at a time. In one form, wherein each leaf has printed thereon a section of the map on each side, the tab or finger grip on one leaf coincides with the tab on the correlated leaf, and a mark or sign on the first leaf is opposite the tab of the leaf next to the correlated leaf, whereby when the tab opposite the mark is grasped and its leaf, with the intervening leaves is turned, the correlated leaf is exposed. In another form wherein each leaf has a section of the map printed on one side only, a mark or sign on one leaf coincides with a tab on the correlated leaf in a north-south or south-north route, whereby the thumb can be placed on this tab and the intervening leaves turned over to expose the next part of the route. In this form the number of tab locations or positions is greater than the number of leaves making one horizontal strip of the map, so that the tabs in the book of the correlated sections of the map in a north-south or southnorth route do not coincide. The tab locations of the second form may be applied to the first form and vice versa.

Title: Treatment of petroleum distillates
Inventor: RICHARD GEOFFREY PERCY
IPC: C10G29/16
Filed: 1952-10-23
Abstract: Hydrogenated petroleum distillates are treated to reduce their corrosivity to metals by contacting the distillates, which have not been substantially oxidized, in the vapour phase with finely divided copper, copper-containing alloys or cupric oxide at an elevated temperature below the temperature at which substantial degradation of the petroleum distillate occurs.  A copper alloy specified is copper bronze.  The copper or cupric oxide may be supported on an inert support such as pumice, silica gel, montmorillonite and silica.  The treatment may be carried out at 230-600 DEG F. and a space velocity of 1-100 v/v hr.  Alternatively, the copper or cupric oxide on the inert support may first be heated to 250 DEG -350 DEG C. and then used to treat the distillate at 150-250 DEG C.  The treatment of hydrofined white spirit is described, and compared with the treatment of hypochorite-treated white spirit.  The first Provisional Specification refers also to the treatment of raw white spirit.

Abstract: 1311542 Graft polymerization process INRESCOR AG FUR INDUSTRIELLE FORSCHUNG UND STRAHLENNUTZUNG 3 June 1970 [6 June 1969] 26793/70 Addition to 1279709 Heading C3G A process for the preparation of graft polymers and copolymers comprises graft polymerizing or copolymerizing at least one freeradical polymerizable monomer on to a polymeric substrate comprising a polyester, a polyamide, a polyacrylonitrile or a polyolefin using high energy ionizing radiation or U.V. radiation, the graft polymerization or copolymerization being effected at a temperature within the glass transition temperature range of the polymer forming the substrate, and the said monomer and the said polymeric substrate being brought to the reaction temperature at least twice in successive heating stages and cooled between each heating stage. Each heating stage is advantageously effected over a period of from 5 seconds to 5 minutes. It is advantageous that temperatures within the range 50-80‹ C. are not exceeded. Suitable grafting monomers are vinyl or allyl compounds, e.g. acrylic acid and methacrylic acid. The polymerizable monomers may be applied to the substrate in the form of aqueous solutions, solutions in organic solvents, emulsions, suspensions or in the gaseous phase. The process may be performed by rapidly heating the substrate and part of the polymerizable monomer to the glass transition temperature range, jointly irradiating, subsequently immediately cooling, and then adding the remainder of the polymerizable monomer. The system is then brought again to the reaction temperature and irradiated. Alternatively the substrate may be irradiated alone at a temperature below its glass transition temperature range, preferably at ambient temperature, and then substrate together with part of the polymerizable monomer is heated to a reaction temperature within the glass transition temperature range and subsequently cooling. In both alternatives the cycle may be repeated until the desired yield is obtained. The substrate may be wetted with water during any treatment stage prior to irradiation. In both cases the irradiation of the substrate and/or its joint heating with the polymerizable monomer may advantageously be effected under oxygenfree conditions. Furthermore the substrate may be heated with a given quantity of polymerizable monomer and then no more of such monomer is added. In the examples (a) a polyethylene glycol terephthalate fabric is grafted with methacrylic acid (1), acrylic acid (2), or a mixture of itaconic acid and acrylamide (4) in aqueous medium; (b) a polyethylene glycol terephthalate foil is grafted with acrylic acid in aqueous medium (5); (c) a polyacrylonitrile fabric is grafted either with acrylic acid or methacrylic acid in aqueous medium (3); (d) a polyepsiloncaprolactam fabric is grafted with a mixture of itaconic acid and acrylamide in aqueous medium (6); and (e) a polyhexamethylene adipamide fabric is grafted with acrylic acid in aqueous medium (7).
