Abstract: A radiation thermometer comprises a housing (1) within which is mounted a radiation detector system including a radiation sensor (2) positioned to receive radiation through a window (5) in the housing. The radiation detector system generates an electrical signal related to the sensed radiation. An optical signal generator (11, 14) is responsive to the electrical signal from the radiation detector system (9) and an internal housing temperature detector to generate a modulated optical signal whose frequency is related to the electrical signal from the radiation sensor and whose mark-space ratio is related to the signal from the internal temperature detector. The housing (1) is connectable with an optical waveguide, such as an optical fibre (16), into which the optical signal is coupled in use. A power source (13) is mounted within the housing (1) and is connected to the detector system (9).

Each of the panels preferably also has a holding structure adapted to permit the device to be carried or held in a signaling position with one hand.

Abstract: The detector has two disc shaped magnets that are magnetized through their respective thicknesses. One magnet is fixedly coupled to a container, and the other magnet is left free to slide transversely with respect to the fixed magnet. The magnets are oriented so that the opposite poles of the magnets are adjacent to each other. In the absence of a shock acting on the container, the free magnet remains in a centered position with respect to the fixed magnet. Indicating apparatus is provided to indicate when the free magnet is moved to an off-center position due to an accelerational force, and the direction of the accelerational force. In one embodiment, the indicating apparatus includes a marking device coupled to the free magnet and a recording surface coupled to the container. In another embodiment, the indicating apparatus includes a transparent cover and tabs for retaining the off-center free magnet.

Abstract: An indicator unit which can be fixed on a tilted steering wheel for indicating the turn condition of the wheel. The indicator mainly includes a base member secured to the wheel, a bias-weighted member pivotally mounted on the base member to maintain itself in an upright position during rotation of the base member with that wheel, a ball-shaped member laid between the base member and the bias-weighted member, constrained by a spiral groove and a radial slot separately furnished on the two members so that the relative rotation between the two members causes the ball-shaped member to move along the radial slot of the bias-weighted member, and a pointed member pivoted on the bias-weighted member and having a curved slot which crosses the ball-shaped member so as to convert the radial movement of the ball-shaped member into swing motion of the pointer member, thus indicating the corresponding turning direction of the car wheel relative to the turning of the steering wheel.

Abstract: A temperature measuring sensor arrangement is described, which can be inserted into or removed from an enamelled built in part in a simple manner without a need for specific tools. A measuring insert with a carrier is provided, along the length of which an outwardly protruding detent element in the form of a collar is provided, and from the lower end surface of which carrier one or several measuring sensors are protruding. The carrier is slidably arranged in a longitudinal direction in a guiding tube and is biased downwardly by a spring engaging between the detent element and a shoulder in the guiding tube. A stop protruding from the inner wall of the guiding tube limits the displacement of the biased carrier.

Abstract: The locating of structural members disposed within the interstices of a concrete member can be accomplished by employing at least one indicator capable of showing the position of the structural member. The indicator also can show the directional location of the support members. The indicator of the present invention generally connects to a post member. This post member provides vertical support for the indicator system. A clamping assembly is attached to the post member and connects the structural member to the indicator system for fixing the location of the structural member. The clamping system can also identify the location of the structural member, and the indicator can then be provided to show the directional line of the structural member. Typically, the post member is sized to a predetermined length so that the longitudinal dimension of the indicator system corresponds to the thickness of the concrete member.

Abstract: A normally upstanding road marker includes a cone extending from a special base formed of an elastomeric material to induce a self righting movement to return the road marker to an upstanding position subsequent to it having been tipped over. The base includes a peripheral edge of undulating configuration defining a plurality of radially extending flaps and an annular depression for focusing bending of the base along a line radially inwardly of at least some of the flaps.

Abstract: The heat transfer coefficient distribution on the surface of a component is measured by removing a predetermined amount of material from the surface of the component and replacing it with an insert comprising a layer of low thermal conductivity material, an array of temperature sensors, and a heater. The heat transfer coefficient is determined by applying a known amount of heat flux to the component by way of the heater and sensing the outputs of the temperature sensors. This procedure is carried out on actual hardware rather than on simplistic scale models of hardware.

Abstract: Self-opening and closing flag material (20) is mounted on a largest flagpole element (34) of a telescoping flagpole and this element can be extended on a smaller element from an elongated compartment (14) of a motor vehicle (10) upon depression of a switch (50) from within the motor vehicle for signalling others of distress. The automatically-deployed flag material is attached to a spar (18a, 18b) which is hingedly attached to the largest flagpole element and the flexible flag material is connected between the largest flagpole element and the spar. When the spar is moved out of the elongated compartment it is biased to hinge away from the largest flagpole element, thereby expanding the flexible flag material into the shape of a V. When the spar is moved into the elongated compartment, it is automatically hinged to close the flexible material against the largest flagpole element.
