  • Patent number: 8215082
    Abstract: A substantially flat roof has elongated log-shaped members arranged horizontally in adjacent, side-by-side relation. Each log-shaped member has a contoured upper surface, and the contoured upper surfaces of adjacent members define a space between them that tapers from a maximum width at the highest elevation of the contoured surfaces to a minimum width where the contoured surfaces of adjacent log-shaped members are closest together. Elongated inserts are arranged between the contoured upper surfaces. Each insert has a wide portion that abuts an adjacent pair of the contoured upper surfaces at a relatively high elevation, and tapers to a narrow portion that abuts the contoured surfaces at a relatively low elevation substantially at the ends of the adjacent pair of log-shaped members. Rain falling on the roof drains by gravity from the contoured upper surfaces to the inserts and along the inserts towards their narrow portions and falls from the roof.

  • Patent number: 8122657
    Abstract: Hollow metal “logs” each extending usually horizontally are arranged in adjacent, parallel, spaced-apart relation to form, or be part of, a wall or roof. Rigid insulating members are inserted between the logs. Each insulating member is shaped to fit around a log on either side of the insulating member. Each insulating member has a pair of outer faces respectively on either side of the wall or roof and lying substantially in respective planes parallel to the axes of the logs. The insulating members abut one another and collectively surround the logs and insulate the wall or roof.

  • Patent number: 8099917
    Abstract: A U-shaped rigidifying member cooperates with parallel metal “logs” each usually extending horizontally. A curved portion of the U wraps halfway around a first log, and first and second legs respectively descend in parallel from opposite sides of the curved portion. The legs are substantially tangent to a second log. This structure is repeated with the U-shaped members overlapping and inverted or otherwise oriented to shed rain, and forms all or part of a wall or sloping roof of a building. The U-shaped members are secured to each other and to the logs to form a continuous structural ensemble that is aesthetically pleasing, even without additional interior and exterior sheathing. It is moreover strong and highly resistant to an external force having a horizontal component parallel to the plane of the wall or roof. The rigidifying members can alternatively be J-shaped.

  • Patent number: 8074413
    Abstract: A foundation for a building superstructure has a number of hollow foundation tubes laid horizontally on the ground and susceptible to degradation over time by contact with the ground. Each tube is protected by one or both of the following: (1) a reinforcement housed within the tube, shaped conformably to the interior of the tube, and resistant to degradation by contact with the ground; and (2) a membrane surrounding the tube, shaped conformably to the exterior of the tube, and resistant to degradation by contact with the ground. The tubes are arranged to form the footprint of a small building. In completing the building superstructure, other tubes, which need not have the same protection, are stacked on the foundation tubes. Degradation of the foundation tubes over time because of their contact with the ground is rendered inconsequential by the reinforcement or prevented by the membrane.

  • Patent number: 6816438
    Abstract: A clock has a face for telling time, a light for illuminating the face, and a switch for controlling the light. The switch cannot be used for turning the light on when the clock is stored. This conserves the clock battery by preventing accidental discharge of the battery when the clock is stored, for example in a suitcase. A magnifying lens is automatically moved to an optimal position relative to the clock face to magnify the face when the clock is deployed to display the time. The magnifying lens can also be used independently to magnify, and optionally illuminate, another object.

  • Patent number: 6794034
    Abstract: A phenolic resin composition in which the phenolic resin can be smoothly cured at a low temperature while inhibiting the generation of free formaldehyde and trapping free phenol. An epoxy compound is dispersed or dissolved as a hardener in an aqueous phenolic resin solution. The epoxy compound functions not only as a hardener for the phenolic resin but as a trapping agent for free phenol. The phenolic resin has been sulfoalkylated and/or sulfialkylated so as to have improved hydrophilicity.

  • Patent number: 6779395
    Abstract: A device for measuring the flow of a fluid has a primary duct and a bypass arranged in series to the primary duct. The bypass has a first section and a second section. A baffle plate with a hole for the passage of the fluid is arranged in the first section. The second section comprises two parallel secondary ducts. In the first section, a turbulent flow dominates, while the flow in the second section is primarily laminar. If the turbulent effects in the bypass are sufficiently strong, the ratio of the flows in the primary duct and the bypass can be substantially independent of the fluid properties and of the flow rate. By using two parallel secondary ducts in the second section, high flow rates and therefore strongly turbulent effects can be achieved without exceeding the measuring range of the sensor.

  • Patent number: 6763710
    Abstract: To measure the flow in a liquid, the liquid (1) is led in a duct (2) along a flow sensor (3). The flow sensor (3) is integrated together with a processing and control circuit on a semiconductor substrate. It comprises a heating and, symmetrically thereto, two temperature sensors. The flow is determined from the temperature difference between the temperature sensors and/or from the power dissipation of the heating. For calibrating the sensor, a valve (4) is provided by means of which the duct (2) can be interrupted. This arrangement allows a flow measurement of high accuracy.

  • Patent number: 6750522
    Abstract: A sensor is described for measuring the parameters of a fluid, in particular for detecting substances in a gas. It comprises a measuring section (4) on a semiconductor chip (1), which is protected by a housing (3). A partition wall (12) of the housing (3) divides the semiconductor chip (1) into two parts (1a, 1b). The first part (1a) is connected to the outside by means of openings in the housing and carries the measuring section. The second part (1b) is covered by a hardened sealing material (11). The sealing material (11) protects the semiconductor chip (1) from undesired environmental influences. The dividing wall (12) forms a capillary between the chip and the housing, the capillary action of which draws in the sealing material and the end of which stops the sealing material.

  • Patent number: 6744389
    Abstract: The A/D-converter with optional analog preprocessing comprises two analog inputs (I1, I2), wherein a converter (1, 2) is connected to each input for generating a first and a second digital value (D1, D2) respectively. These are fed to a table (3) for generating a lookup value (D). A decimation filter (4) processes several such lookup values and generates an output value (O). With this arrangement the table can be kept comparatively small while it is still possible to reach high resolution and precision. The A/D-converter is especially suited for applications where two or more analog signals have to be combined and digitized.
