Abstract: A door assembly, a hanger bracket therefor and the method of using the bracket to hang the door jamb assembly, in which the door hanger bracket has an elongated body configured to provide a wall mounting tab at each end, such that said bracket can be secured to a door jamb as a unitary bracket and provide a wall mounting tab on each wall at each side of the jamb. The bracket also includes a break line such that it can be broken in two and used either on two different jambs or two different locations on the same side of a single jamb or can be located on opposite sides of the same jamb, where the jamb is too wide for the unitary bracket.

Abstract: A door assembly, a hanger bracket therefor which comprises an elongated manually bendable body which extends from a first wall mounting tab at one end, for a distance approximately equal to the width of a door jamb, and sufficiently far beyond to provide for forming a second wall mounting tab. The elongated body includes at least one bend line extending laterally with respect to the length of said body, whereby the body can be manually bent to form said second wall mounting tab, after the bracket has been secured to the jamb of the door assembly and the door assembly located in the door opening of the wall and secured to one side of the wall by the first wall mounting tab. Two bend lines are shown such that the bracket can be used in a wall having drywall on both sides, or in a wall having drywall on only one side.

The door hanger (140) includes a jamb arm (142) with a triangular shaped edge (144), and proximate shorter edges (145) formed inwardly from the triangular shaped edge (144) and perpendicular to each other. A pair of opposing faces (143) are formed by the triangular shaped edge (144) and the proximate edges (145), and a central hole (146) is located substantially in the center of the opposing faces (143). An alignment flange (150) is perpendicular to the jamb arm (142) and includes a distal arcuate edge (152). The arcuate edge (152) has a configuration substantially conforming to the legs of a triangle. Formed inwardly from the distal arcuate edge (152) are a pair of opposing sides (154), with sets of alignment notches (156) formed on the opposing sides (154).

Abstract: A rear deck lid wing has two pedestals which rotate tighten and slide through a track from left to right for the ability to be installed on various trunk lids. There are two end pieces with brackets that clip under the lip of the trunk lid and fasten with screws and a center piece that can be cut to size for various width trunk lids. It can also be equipped with a third brake light.

Abstract: A fluid measurement system includes two transducers which are located in a duct to provide a measuring path through a measuring tube. The transducers are switchable to allow each to be used for both transmission and reception and the speed of fluid passing through the measuring tube will be depedent on the difference in time periods for a signal from the transducers passing with or against the fluid flow. A calibration mechanism employing an auxiliary transducer with its own ultrasonic paths allows accurate measurment of speed of sound values to be determined to the particular system parameters including transducer delay.

Abstract: A method for bonding together adjoining hollow glass spheres to form an acoustic matching member for a transducer comprises subjecting a mixture of adjoining spheres and a solution of a heat curable resin and a volatile organic solvent to a first temperature to drive off the solvent and then to a second temperature to cure the resin. This causes the spheres to bond together at their points of contact but otherwise voids are formed between the spheres.

Abstract: A measurement system includes a housing 10 with a duct 11 having an inlet 13 and outlet 14. Fluid passes though a number of apertures 47 in a chamber 21 and then through a measuring tube 40 which incorporates extensions 41. Fluid exits via chamber 22 and its apertures 47 to outlet 14. Transducers 36,37 are provided in chambers 53,50 and have an acoustic path through the measuring tube. Control electronics cause the transducers to send a burst of signals in alternate directions through the tube to determine fluid speed.

Abstract: A measurement system for measuring the time for a signal to pass between two transducers TDR1,2 to allow fluid speed or flow to be determined in a gas meter for example. Each transducer can transmit or receive signals. The system is controlled by a microcontroller 31 and a signal with a phase change acts as a marker which is transmitted from transmitter 21 via matching stage 22,23 from one transducer and is received by the other. On receipt via the matching stage and amplifier 24 it is sampled by capacitor array 25 and detected in detector 29. Amplitude information from array 25 is made available to the microcontroller to compute time of signal travel and hence flow rates.

Abstract: A fluid speed measurement device includes a pair of ultrasonic transducers (T1, T2) spaced in a measuring chamber. A transmitter and receiver system is controlled by a microprocessor (100) which generates pulses which periodically invert and these are switched by switches (140, 150) to allow alternate direction of transmission. Reception and detection of signals is effected by blocks (152-168). Time calculation is determined by counter (109) and results are used to calculate flow speed or volume using the microprocessor. A speed increase in the measurement region is effected using a venturi device.

Abstract: An acoustic matching member for a sonic transducer is disclosed which comprises a solid material, for example, a glass, in which a plurality of voids have been formed. A method is also included of forming an acoustic matching member for a transducer which includes the steps of forming the member from a material in which a plurality of voids have been introduced whereby the velocity of sound in the material with voids is substantially less than that of the material without voids in the direction of sound propagation of the member.

Abstract: A fluxgate compass direction sensor in which a fluxgate is mounted relative to a receptacle by means of a flexible circuit. The fluxgate is also suspended in a liquid by means of a float. In use, if the receptacle tilts relative to the horizontal, the level of the liquid will move to retain a horizontal aspect and the float, being buoyant in the liquid, will retain the fluxgate in the horizontal plane. The flexible circuit acts to allow tilting of the float and fluxgate relative to the receptacle while retaining the fluxgate in lateral and directional alignment relative to the receptacle.

Abstract: A speed measurement device for measuring the speed of a ship through the water is disclosed. The device comprises a transmitter circuit and a receiver circuit connected to two transducers T.sub.1, T.sub.2 which are based substantially in the direction of travel of a ship below the water line thereof. Pulse trains are transmitted in both directions between the transducers T.sub.1, T.sub.2 which are received by the receiver circuitry so that a signal is derived indicative of the time taken for the signals to travel both for and against the direction of travel of the ship, this signal being proportional to ship's speed.

Abstract: A suspension system suitable for a flux gate compass having compass windings (14) includes a ball joint (4,5,6) which permits both tilt and twist about a vertical axis, and a separate alignment element (16) for causing the windings to follow twisting motion of the fixed structure. The alignment element takes the form of a flexible printed circuit made into a double spiral form and carrying electrical conductors to provide the electrical connections to the windings. A zig-zag shape may be used instead of a spiral. The suspension does not suffer from the geometric imperfections of a Hooke's joint and avoids the need for separate flexible conductors which can interfere with the suspension operation and can break.
