Abstract: A vibrating beam force transducer includes a piezoelectric beam structure supported at first and second ends, and an oscillator for inducing a vibration in the piezoelectric beam. To permit adjusting the bias frequency of the beam, an adjustment mass is formed at the center of the beam, the adjustment mass made of piezoelectric material. Part of the adjustment mass can be broken off to adjust the bias frequency. The first and second ends are attached to the a support structure by first and second legs at each end of the beam, the legs having an angle therebetween, thereby forming an A-frame mount.

Inventor: HEDSTROEM T
Filed: 1989-02-14
Abstract: When a predetermined level of relative movement between the lines (4) and the platform is reached, a brake device (11) is initiated and activated which acts on the lines. This device takes the form of a clamp arrangement (12, 13) comprising two rails arranged parallel to and movable to and from one another. Each rail has a track facing the lines. - In conjunction with the two rails functions a two arm system (14, 15) which when it moves in one direction causes the rails to move towards each other and clamp the lines. When it moves in the opposite direction, the rails are moved apart. First and second hook components (16, 17) are fitted to the clamp arrangement, holding it in an inactive position. A further device (20) can disengage the hook components, allowing the rails to clamp against the lines (4).

Date Jul. 11, 1991.Arrangement for effective oil supply to a working chamber in a hydrodynamic coupling flushed through with oil, and lubrication of the bearings of the coupling. The working chamber is supplied with oil through a channel in the stationary part of the coupling via a main bearing forming part of the coupling and bearing the turbine in the pump wheel. A second main bearing bearing the pump wheel in the stationary part receives a continuously limited throughflow of lubricating oil via a throttle in communication with the flow of oil to the first main bearing. By means of the invention, a steady flow of oil to the working chamber of the coupling is obtained, and at the same time all the main bearings receive a continuous throughflow of lubricating oil which does not cause any great oil friction losses in the bearings during stationary running. The invention is advantageously applied to hydrodynamic couplings in internal combustion engine units of the compound type, where a turbine driven by exhaust gas transmits surplus energy from the exhaust gases via the coupling to the crankshaft of the engine.

Abstract: An optical method for detecting and classifying precipitation involves an arrangement contg. a radiation source and detection system. The radiation coincides with a detection region. The vertical extent of the light beam is less than the diagram of the largest particle to be detected or between 0.1 and 1 mm. The horizontal extent is greater than the vertical extent. Large rain drops can be distinguised from small ones since they cause shorter pulses. Snow can be distinguised from rain since snow drops cause oonger pulses than rain drops. USE - Optical detection and classification of precipitation.

Abstract: The invention relates to a method and an arrangement for splicing optical waveguides and, more specifically, for effecting such splicing under field conditions i.e. directly in cable pits where the waveguides requiring splicing are housed. In accordance with the invention, a solidifiable refractive-index matching means (4) is used to effect the splicing. The index-matching means (4) is applied between the ends of the two waveguides (1) in a support arrangement (2) and is then solidified to form a splice having optical, ageing and temperature characteristics substantially corresponding to those of the waveguides (1). The temperature at which solidification is effected can be such that the refractive index-matching means is sintered to form a glass splice. The index-matching means is preferably a silica gel which can be solidified either chemically or by the application of heat. <IMAGE>

Abstract: Transmitting signals containing amplitude modulated (AM) and phase modulation (PM) components requires a transmitter having AM and PM control loops. The PM control loop provides phase modulation, frequency translation and phase predistortion for the transmitter. The phase predistortion/correction is accomplished by using an oscillator, thus, the amount of PA phase correction is essentially unlimited. Additionally, the PM control loop is nested about a power amplifier (PA), allowing the PM control loop to correct for any distortion introduced by the PA.
