Tensioning arrangement for a power-transmitting element incorporated in a transmission

Abstract: A tensioning arrangement for a chain incorporated in a transmission and intended to be driven in an endless path. The tensioning arrangement comprises a spring element that acts on a piston to move it outwards to tension the chain when the transmission is not in operation. The tensioning arrangement is also designed with a space that is supplied with oil when the transmission is in operation, in which connection the oil imparts to the piston a limited inward movement to slacken the chain.

Shielding Effectiveness of Modern Energy-Saving Glasses and Windows

Abstract: Thin metal coatings on glass are widely used in modern windows to improve their thermal properties. However, while there are some available papers on the properties of microwave propagation through commercial metallized windows glass below 6 GHz there seems to be a lack of papers regarding metallized multiglazed windows at higher frequencies. Such data are of the great importance when designing modern microwave communication systems working in urban environments. In this paper, the shielding effectiveness (SE) of modern energy-saving glasses and windows were investigated at microwave frequencies from 1 to 20 GHz. Wide measurement range together with proposed fast calculation procedure based on the matrix multiplication method, allowed us to elucidate the reasons responsible for the extremes in dependencies of SE on frequency. It was also shown that by comparing measured and calculated results, the conductivity of the thin metallic layer used in modern energy-saving windows can be determined. During the study, we found that attenuation of microwave radiation passing through modern windows can be as high as 60 dB.

Load-bearing bracket intended to be mounted on a longitudinal roof rail of a motor vehicle

Abstract: Load-bearing bracket (10) intended to be mounted on a longitudinal roof rail (12) of a motor vehicle. The bracket (10) comprises a load-supporting bar (14) which is substantially horizontal in the position of use, is directed transversely with respect to the roof rail and has attachments (18) for load-fastening means at the end portions (16) of the bar. On the underside, the bar (14) has an anchoring means (20) in the form of a pair of downwardly projecting, resilient legs (22) which are formed in one piece with the bar (14) so that, when mounted on the roof rail (12), they straddle said roof rail (12) and are anchored thereon. The bar (14) extends as a cantilever support in one or both directions from the anchoring means (20) of the bracket and transversely across the roof rail (12).

Arrangement for suspending a forwardly tippable cab on a vehicle

Abstract: The invention relates to an arrangement for the suspension of a forwardly tippable cab (1) on a vehicle frame (2) with at least one spring means (50) and one movement restrainer (65) arranged between the cab (1) and the frame (2), said spring means (50) being adapted to absorb the oscillations of the cab (1) and the restrainer (65) being adapted for restricting the vertical movement of the cab (1) relative the frame (2). When tipping the cab (1) on the kind of vehicle mentioned above, the centre of gravity of the cab (1) is moved, whereby the weight of the cab (1) is successively transferred to the spring means (50). The latter then contracts and the necessary play between the vehicle drive unit (1) and lower portions of the cab (1) necessary for tipping the cab decreases, resulting in that the cab can collide with the drive unit (8). The invention has the object of counteracting the cab sinking during the tipping sequence, and the invention is distinguished in that both the spring means (50) and the movement restrainer (65) each has a support mounting (60 and 68) in the carrying parts of the cab (1) and that the support mounting (68) of the movement restrainer (65) is arranged forward of the support mounting (60) of the spring means (50).

Development of an Adaptable Monitoring Package for marine renewable energy

Abstract: The Adaptable Monitoring Package (AMP) along with a Remotely Operated Vehicle (ROV) and custom tool skid, is being developed to support near-field (≤10 meters) and long-range monitoring of hydrokinetic energy converters. The goal for the AMP is to develop a system capable of supporting a wide range of environmental monitoring in harsh oceanographic conditions, at a cost in line with other aspects of technology demonstrations. This paper presents a system description of all related infrastructure for the AMP, including supported instrumentation, deployment ROV and tool skid, launch platform, and docking station. Design requirements are driven by the monitoring instrumentation and the strong waves and currents that typify marine renewable energy sites. Hydrodynamic conditions from the Pacific Marine Energy Centers wave test sites and Admiralty Inlet, Puget Sound, Washington are considered in the design as early adoption case studies. A methodology is presented to increase the capabilities to deploy and operate the AMP in strong currents by augmenting thrust and optimizing the system drag profile through computational fluid dynamic modeling. Preliminary results suggest that the AMP should be deployable in turbulent environments with mean flow velocities up to 1 m/s.
