Inventor: MOEGLEIN MARK
IPC: G01S19/07
Filed: 2000-10-26
Abstract: Methods and apparatuses which use satellite position system (SPS) reference receivers. In one example of the invention, a plurality of SPS reference receivers, such as Global Positioning System (GPS) reference receivers, each having a known position, are dispersed over a geographical region. Each of the SPS reference receivers transmits into a communication network, a representation of at least a portion of a satellite navigation message, such as satellite ephemeris data, received from SPS satellites in view of the particular SPS reference receiver. A plurality of digital processing systems, such as a first and a second digital processing systems, are coupled to the communication network to receive the satellite ephemeris data which is transmitted through the communication network. The first digital processing system receives a first pseudorange data from a first SPS mobile receiver and calculates a first position information of the first SPS mobile receiver from a representation of the first pseudorange data and from satellite ephemeris data received from the communication network. The first digital processing system may also receive pseudorange corrections from the communication network and use these corrections to correct the first pseudorange data to provide the representation of the first pseudorange data. The second digital processing system receives a second pseudorange data from a second SPS mobile receiver and calculates a second position of the second SPS mobile receiver using the second pseudorange data (which may be corrected using pseudorange corrections from the communication network) and using satellite ephemeris data received from the communication network. In one embodiment of this example of the invention, the mobile SPS receivers are communicatively coupled with the digital processing systems in part through a wireless cell based communication system. A further digital processing system may also be coupled to the communication network to receive pseudorange correction data and to provide merged pseudorange correction data to the digital processing systems through the communication network.

Abstract: 1,035,420. Pens for recording instruments. HONEYWELL Inc. June 22, 1965 [July 1, 1964], No. 26265/65. Heading B6P. In a pen recorder, ink is fed from a container 4 to a reservoir 10 associated with the pen 13 via two capillary tubes 15 and 17, each tube having a part thereof wound in helix fashion around the guide bar 8 of the pen carriage 9. Each helix is wound in the opposite sense to the other, so tending to cancel out any forces on the pen. The container 4, which is compressible, or at least has a compressible portion, is squeezed to prime the reservoir 10 having previously covered the air vent 20. The two capillary tubes open into the reservoir 10, Fig. 2 (not shown), and the arrangement is such that on filling the reservoir through one or both tubes a pocket of air becomes trapped above the surface of the ink. One of the capillary tubes, for instance 17, may be sealed at an end remote from the pen and not lead to the container 4.

Abstract: 1,050,118. Sodium sulphate. COURTAULDS Ltd. Sept. 3, 1963 [Sept. 3, 1962], No. 33668/62. Heading C1A. Anhydrous Na 2 SO 4  is isolated from viscose spin bath liquor containing Na 2 SO 4  and H 2 SO 4  by metering the liquor and an alcohol of boiling point less than 100‹ C. into a mixture of the liquor and the alcohol maintained at above 33‹ C. and below the boiling point of the alcohol; the liquor and the alcohol are fed into the mixture in predetermined proportions so that anhydrous Na 2 SO 4  is precipitated, the precipitate is separated and alcohol is distilled from the separated liquid and recycled as the whole or part of the alcohol metered to the mixture. The alcohol may be methanol, ethanol or isopropanol. The process may be carried out in a vessel in which a rotary cylindrical filter is partially submerged, the anhydrous Na 2 SO 4  being removed from the separator. The anhydrous Na 2 SO 4  so produced may be washed with alcohol having a boiling point less than 100‹ C. The alcoholic wash liquor may be made alkaline by the dissolution of NaOH. The efficiency of the process is increased if some of the alcoholic vapour from the distillation of the filtrate is condensed in contact with the mixture so as to maintain the temperature in the range 50-70‹ C.

Abstract: 1,051,155. Rollers. PRODUCTION MACHINERY CORPORATION. Sept. 11, 1963 [Dec. 6, 1962], No. 35815/63. Heading F2U. A roller for automatically centring a moving strip passing thereover comprises a body covered with rubber or rubber-like material which circumferentially elongates under the force of the strip, the arrangement being such that greater circumferential elongation is produced at the central portion than at the end portions of the roller when a strip passes thereover. The portion of the strip in contact with the central portion of the roller thus tends to move faster than the portions contacting the end portions of the roller so that if the strip deviates from a central position a couple is exerted on it restoring it to its central position. The differential elongation may be produced, as shown in Figure 2, by forming the central portion 44 of softer rubber than the end portion 40, 42 of the roller, the strip 10 sagging somewhat into the central portion; alternatively the central portion may be formed of the same rubber as the end portions but of a greater thickness. If the strip 10 is relatively stiff so that it will not sag into the central portion the differential elongation is produced by forming the end portions of the same rubber as the cen - tral portion but of a greater thickness.

Abstract: 1,225,432. Bagging refuse. DEMAG A.G. 25 April, 1968 [26 April, 1967], No. 19648/68. Heading B8C. Apparatus for forming bales of refuse and placing them in bags 20 comprises an upright reciprocable cylinder 4 open at the top and having an openable bottom closure 22, or 22a, Fig. 2 (not shown), and a pressing head 2 stationary during compressing, fitting within the cylinder, the arrangement being such that a bag rim 21 may be clamped round the lower end of the cylinder when the bottom closure is open and the closure is then closed to support the bag during upward movements of the cylinder. When the desired bale is formed, the bottom closure is opened and the next upward reciprocation of the cylinder causes the head to eject the bale into the bag. Pressing head 2 is carried on an upwardly urged section 3b of a telescopic rod 3, which is locked in its extended position by a catch 19. Section 3b is connected to a spring or counter weight by means of a cable (not shown). The cylinder is raised by means of an electric motor 11, or a piston-and-cylinder (14) and (15).

Abstract: 1,225,909. Self-processing cameras. POLAROID CORP. June 19, 1969 [June 21, 1968], No.31132/69. Heading G2A. In an apparatus in which an exposed photosensitive sheet and a copy sheet are passed together between a pair of pressure rollers 58, 60, a layer of processing liquid being spread between the sheets to effect an image transfer, the speed of movement of the sheets is varied directly as the ambient temperature, so as to compensate for temperature-related changes in the viscosity of the liquid. This is preferably of a thixotropic nature, and the arrangement enables the thickness of the processing liquid to be maintained at a constant value in spite of temperature variations. As shown, the drive to the rollers derives from a battery-driven motor 66 via a chain of gear-wheels. Roller 60 is fixed, and roller 58 is biased towards it by levers 62 urged by springs 64. The ambient temperature is sensed by a thermistor 84 connected in a conventional bridge circuit, across which is connected the battery 68 and motor 66. Thus the speed of the motor, and hence the movement of the film unit, varies directly with the temperature.

Abstract: 1,227,196. Magnetic data storage arrangements. WESTERN ELECTRIC CO. Inc. 27 Aug., 1968 [31 Aug., 1967], No. 40921/68. Heading H3B. In a magnetic data store in which a movable single wall domain in a sheet of a single crystal magnetic material, such as a rare earth orthoferrite, is detected at a read out position by utilizing the Faraday rotation of transmitted light, the thickness T of the sheet is chosen such as to give a maximum rotational difference of transmitted light for distinguishing between the presence and absence of a single wall domain at the read out position. This sheet thickness is given by the relation T= (n + ¢)#, where 8 is the thickness of a sheet of magnetic material for 2# retardation between the birefringent components of the transmitted light, and n is a whole number. As shown in Fig. 1, single wall domains may be established in a sheet 11 of yttrium orthoferrite and moved to a read out position 12. The transmitted light originates at a monochromatic source 13 which is preferably a helium-neon laser and is polarized by a polarizer 21. After passing through the sheet 11 the transmitted light is detected by a detector 14. An analyser 23 and a quarter wave plate 22 are provided to prevent light from passing to the detector when a single wall domain is absent from the read out position.

Abstract: 1,227,253. Reciprocating conveyers. SIMPLEX CORP. 7 Aug., 1968 [22 Aug., 1967], No. 37698/68. Heading B8A. A transfer system includes recesses 92 which provide stations for articles supported on fixed plates 16 and guided by rails 20. The articles, e.g. as shown at A, are transferred, from left to right, by carriers 110 from a station to the next succeeding station, the carriers being under the control of sensing means and control means which are both mechanical. A sensing lever 94 at an empty station (shown to the right of Fig. 2) has a lower trigger portion 102 in the path of a roller 104 carried by a strip element 69a, Fig. 4. This element is one of a series, each element being pivotally connected to a lower continuous strip 66 by links 80, 82. When the strip 66 is moved to the right by a piston-rod 90, the element 69a is raised to the position shown in Fig. 4, the carrier 110 also being raised to an operative position. The carrier is connected to a slide 34 by parallel links 112, the slide comprising elongated bars 36 mounted on rollers 28 of pivoted levers 26. Counter-clockwise pivoting of these levers by a link (30) causes the carrier to be further raised so as to lift the article A clear of the plates (16), Fig. 5 (not shown). The carrier having been completely raised, the strip 66 may be returned to the left and the elements 69 lowered. A bearing block 40 connected to the slide 34 is then moved to the right by a pistonoperated arm 58 and the article is positioned above the next succeeding station. Pivoting the levers 26 to their original position then causes the article to be deposited at the station after which the slide 34 is returned to the left by rocking the arm 58. Due to the initial presence of the article A at the station to the left of Fig. 2, the associated sensing lever 94 has its lower portion 102 raised and does not engage the roller 104 below it. Accordingly the carrier (not shown) preceding the station is not brought into operation.

In a coaxial pipe system in which there is to be a temperature difference between the pipes, a spacer comprises an elongated carrier 4 which carries supporting elements 5 whose dimensions, and/or composition, enable them to function as thermal insulators. The shape of the supporting elements 5 on the side facing away from the carrier are preferably such as to give point, or line, contact between the supporting elements and the pipe surrounding them. The supporting elements 5, preferably hollow and made of methyl methacrylate polymer, can be spherical bodies as shown in Fig. 3, threaded on a nylon string, or cylindrical, or tube, shaped rollers. Rectangular bodies of T-shaped cross-section, Fig. 7 (not shown), are carried by a ribbon (6), e.g. of polyester, or polystyrene. The distances between the supporting elements may vary or, they may be arranged in groups spaced from each other by a distance greater than the distance between the elements within a group, and the elements in different sections of the carrier may have different heights. The lengths of the sections of carrier each carrying a group of supporting elements of equal height corresponds to the circumference of the pipe within the spacer, the groups of supporting elements of different heights preferably being in alternate sections of the carrier. In an arrangement of three coaxially disposed pipes 1, 2, 3, Fig. 1 (not shown), the inner pipe 1 is adapted to carry electric conductors in the superconductive condition and is filled with liquid helium at a temperature of approximately 4‹ K., the space between the pipes 1 and 2 is evacuated and the space between the pipes 2 and 3 is filled with liquid nitrogen at an approximate temperature of 77‹ K.
