Filed: 2009-12-03
Abstract: A map data processor including: a road map database 24 storing road map data having link data relating to a road segment in the road map data, the link data including setting information showing the status of the link; and road network information including connection information between links. A communication means obtains from an external device, new link data including connection object setting information such as road name, road type etc., and coordinate information relating to one end of the new link. A controller 29 extracts link data from the road map data, the link data relating to a link disposed in a predetermined geographical area with a centre of the co-ordinates being at one end of the new link, The controller determines that the new link is connected to an extracted link when the connection object setting information matches. The controller subsequently registers the new link data, the connection information between the new link and the connection object link in the road map data.

Title: New polyoxy--ß-acylaminoanthraquinones and process for their manufacture
IPC: C09B1/516
Filed: 1956-03-29
Abstract: The invention comprises polyoxyanthraquinones which contain a single anthraquinone nucleus having two hydroxy groups in a -positions of one of the benzene rings and in at least one b -position of the anthraquinone nucleus a primary amino group monoacylated by the residue of a monocarboxylic acid.  They are made by acylation of the corresponding unacylated amino polyoxyanthraquinone, and this process may be carried out in a solvent such as nitrobenzene or chlorbenzene, and in presence of an acid-binding agent such as pyridine or dimethylaniline.  The products dye or print polyesters, cellulose esters and ethers, nylon, and polyurethanes.  Mixtures of starting materials may be used.  In examples, 1,4-dioxy-2-aminoanthraquinone, 1,4,5,8 - tetraoxy - 2 - aminoanthraquinone, 1,4,5 - trioxy - 2 - or- 3 - aminoanthraquinone, and 1,5,8-trioxy-2-aminoanthraquinone are acylated with acetyl, butyryl, benzoyl, p-toluyl, hexahydrobenzoyl, and lauroyl chlorides.  Dyeing examples describe the dyeing of polyester fibres at high temperature under pressure or with a swelling-agent at atmospheric pressure.  1,4 - Dioxy - 2 - aminoanthraquinone, 1,4,5,8 - tetraoxy - anthraquinone, and 1,4,5 - trioxy - 2 - or 3-aminoanthraquinone are made by reaction of the corresponding non-aminated bodies with hydroxylamine hydrochloride in alkaline solution.

Title: Arrangement in air-blast electric circuit-breakers
IPC: H01H33/32
Filed: 1959-03-24
Abstract: 853,243. Air-blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. March 24, 1959 [March 25, 1958], No. 10106/59. Class 38 (5). In an air-blast circuit-breaker compressed air from a pipe 16 is supplied to a control-air container 11 through a non-return valve 18, and to an air-blast container 10 through a non-return valve 17 and a normally open stop valve 19 controlled by a differential piston 21. Normally the container 1, housing a stationary contact 2 and a nozzle-shaped movable contact 3, is permanently filled with compressed air and the breaker is operated by admitting control air to space 6, normally at atmospheric pressure, through a valve 14 to depress a spring-controlled piston 4, thus allowing blast air to flow out through a channel 9 and a valve 15, which closes when the breaking gap is fully opened. Should the air pressure in container 10 decrease beyond a predetermined value due to a leak, the valve 19 is closed by the piston 21 to maintain the pressure in the pipe 16 and thus prevent a pressure drop in the control-air system (due to normal leakage) causing undesirable closing of the moving contact 3. The piston design is such that pressure differences caused during normal operation of the breaker do not actuate the valve 19. A spring 20 is provided to keep the valve 19 open when containers 10, 11 are empty of air.

Title: Improvements in or relating to apparatus and method for determining hydrogen contentin hydrocarbon substance
Inventor: JACOBS ROBERT B
IPC: G01N23/08
Filed: 1956-04-03
Abstract: 807,103. Radiation absorption measuring apparatus. STANDARD OIL CO. April 3, 1956, No. 10198/56. Class 40 (3). An arrangement for determining the proportion of hydrogen in a hydrogen-containing substance includes means for determining the absorption coefficient of the substance for betaray radiation. From a knowledge of this and the specific gravity of the substance (for the determination of which means is also provided) the hydrogen content may be calculated. To determine the beta-ray absorption coefficient the invention provides apparatus, shown generally in Fig. 1, comprising a pair of ionization chambers 14, 22 responsive to beta-ray radiation from a source 10, chamber 14 receiving the radiation passing through a sample of the (fluid) substance contained in a sample cell 11, via an adjustable calibrated wedge absorber 13 and pre-set compensating wedge 12 whilst chamber 22 receives radiation passing through a standard absorber 21. In operation the fluid to be examined is poured into a reservoir 49, which communicates with the sample cell 11 by means of a duct 55, and its specific gravity determined from the reading of a calibrated torsion balance to the arm of which a bob of known mass is attached so as to be freely suspended in the fluid (Fig. 8, not shown). Both the reservoir 49 and the sample cell 11 are formed in a massive coffer block 48 so that the temperature at which the specific gravity is determined is the same as that of the fluid (in the cell 11) utilized for the beta-ray absorption coefficient measurement. The latter measurement is then effected by adjusting the calibrating wedge 13, the reading of which gives the required value, until a " null " reading is obtained on an indicating meter 19 the chambers 14, 22 being oppositely polarized by battery 15 so that equal and opposite currents flow in the chambers when the absorption of beta-rays by the standard absorber 21 is the same as that due to the sample and the wedge 13. In order to maintain constant relative sensitivity between the two chambers the latter are connected together by means of an (electrically) insulated " breathing " tube 28 which keeps the gas in both chambers at the same temperature, pressure and humidity, errors due to the random nature of the production of beta-rays by the source 10 being reduced by the distributed capacity of the screened cables 44, 45 and 46 which forms the input capacity to an electrometer circuit (Fig. 11, not shown) associated with the indicating meter 19. The Specification gives details of constructional features of the complete apparatus including the calibrated control mechanism for the wedge 13, the sample cell and reservoir 11 and 49, and the preparation of the beta-ray source 10, and describes a shutter arrangement for screening the source whilst adjusting the zero of the meter 19.

In a line deflection circuit for a television receiver having a supply boosting circuit comprising capacitors 62, 64 and a linearitycontrolling inductor 59, arranged as shown, a capacitor 66 is bridged across inductor 59 for the purpose of reducing the effect of small changes in capacitors 62, 64 on the circuit performance. It is shown, that when valve 24 is non-conductive and diode 54 conductive, the damping impedance on the oscillatory circuit formed by the inductance and capacitor of transformer 26 and deflection coils 27, 28 is formed by the series combination of capacitors 66 and 64 whereas the effective supply boosting impedance, when valve 24 is conductive is formed by the series combination of capacitors 66 and 62. The circuit 59, 62, 64 should be tuned to the deflection frequency.
