  • Wild turkey call
    Patent number: 4576584
    Abstract: A turkey call capable of realistically imitating both the gobbling and clucking sounds made by wild turkeys. A hollow body has an internal sound chamber covered at one end by a vibratile diaphragm. An air bulb is mounted on the opposite end of the body and can be squeezed to vary the gobbling sound produced by the diaphragm. A hammer and anvil mechanism in the sound chamber reproduces the clucking sounds made by wild turkeys and can be activated independently of the diaphragm.

  • Portable temporary emergency distress signal
    Patent number: 4574726
    Abstract: A portable, temporary, emergency distress signal capable of being collapsed and carried in the dash compartment of an automobile or quickly erected and placed on the outside of a stranded vehicle includes a telescopable, rod type staff, a magnet base and a fabric flag. The flag is rollable into a small roll, but held outstretched in use by a three section, pivot jointed, rod fitted into the edge seams. The telescopable staff is pivoted to the magnet base so that the staff may be vertical on top of the vehicle or at right angles, on the side of the vehicle. A sleeve lock slides over the pivot to hold the staff vertical, a sleeve lock stop holds the sleeve lock out of the way when the staff is at right angles to the magnet and the sleeve lock is threadedly secured.

  • Optical fibre thermometer
    Patent number: 4575259
    Abstract: An optical fiber temperature thermometer uses a thermochromic substance having optical absorption peaks which vary with temperature within a first waveband, and having substantially constant absorption with temperature in a second waveband. The radiation employed is in a wide band to include the first and second wavebands, and the radiation, reflected and attenuated as a result of the passage through the thermochromic substance, is split into two selected beams and filtered in narrow band pass filters for the first and second wavebands, to supply optical signals to respective detectors whose outputs are divided to produce a ratio signal representative of the temperature. The sensor is sufficiently compact for biomedical use, and, being unaffected by electromagnetic fields, is useful in regions of high tension or in microwave heating.

  • Filter differential pressure impending and bypass indicator
    Patent number: 4574728
    Abstract: A differential pressure indicator for use with a filter providing dual indication to indicate both a bypass condition as well as an impending bypass condition. The indicator includes a pressure detector in the form of a piston carrying a pair of permanent magnets. A pair of cylinders each carrying a permanent magnet are concentrically disposed around the permanent magnets carried by the piston. As the differential pressure increases, the piston moves pulling the permanent magnets affixed thereto through the concentrically disposed magnets and as a result of magnetic force interaction the concentrically disposed cylinders move to expose first one and then the other of the cylinders to provide the signals representative of the impending bypass as well as bypass differential pressure being sensed.

  • Thermocouple isolation block system
    Patent number: 4573806
    Abstract: An aircraft engine which may, for example, be a turbine engine, is provided with an engine temperature thermocouple harness for monitoring the temperature of the aircraft engine. A protective isolation assembly allows for the use of two separate aircraft circuits coupled to receive temperature indicating signals from the thermocouple system. The protective assembly includes two resistors sealed in a metal housing to be connected at the branch point from the existing aircraft temperature monitoring system; and the housing for the protective assembly is electrically and mechanically connected in direct proximity to the thermocouple harness output terminal housing. A short circuit of the second engine temperature monitor circuit would have negligible effect on the existing temperature indicator circuitry in view of the presence of the isolation block assembly.

  • Apparatus for electrically measuring the level of a liquid in a container, particularly in the gasoline tank of a vehicle
    Patent number: 4566322
    Abstract: In a device for the electric measurement of the level of a liquid in a container, particularly in the gasoline tank of a vehicle, a support developed as protective tube of a conductor foil is fastened for swinging against the force of a spring (14 and 21) to the top of the container. In order to be able to arrange the support even in containers in which the point of attachment of the support is lower than the highest level to be detected, the support is subdivided into three approximately rigid sections, (2, 3, 5) each two sections (3, 5) being articulated in the manner of a toggle joint to each other and being under spring action. In this way the outermost section (3) is swung, substantially independently of the inside height of the container, on the one end towards the bottom (4) and on the other end towards the top (1) of the container.

  • Handbell
    Patent number: 4566400
    Abstract: An improved bell is disclosed which features a clapper continuously adjustable for hardness of strike. The clapper comprises a hard inner member and a resilient outer member. The periphery of the clapper is circular but the hard inner member is not circular about the same center as the periphery so that the amount of resilient material between the solid inner core member and the periphery varies circumferentially around the clapper. At the time of manufacture of the bell it is tested to locate the point on the bell body at which "wow and flutter" in the tone emitted by the bell is minimized. A single insulated pin serves to orient the handle of the bell, the bell body and the plane of swing of the clapper. The attachment of the handle, the bell body and the clapper is such as to minimize extraneous noise. An elastomer clapper shaft is employed, and its effective flexing length may be varied.
