Abstract: A truck cargo bed utility box blow molded of high density polyethylene which complements the styling of many truck bedliners. The utility box incorporates a mounting system for a central pneumatic spring which holds the lid of the box open. The mounting system consists of a bracket mounted to a wall forming part of the storage bin and a bracket on the bin lid. The lid bracket and the bin bracket extend to and engage with a hinge pin which joins the lid to thestorage bin. The brackets are constructed of sheet metal and are mechanically joined by the hinge pin. The loads imposed on the lid and bin wall by the air spring are distributed through the hinge pin. The bin bracket is also attached to a metal rim which surrounds the opening into the box to provide load distribution.The metal rim provides a distortion resistant structure to which locking hasps can reliably latch. By distributing the loads imposed on the plastic lid and plastic bin distortion of the plastic is prevented.

Title: Method of constructing fully dense metal molds and parts
Inventor: TOBIN JAMES ROBERT
IPC: B29C33/38
Filed: 1996-01-05
Granted: 2001-09-04
Abstract: A method of constructing a fully dense metal part or a metal mold half for mating with another mold half to form a mold for casting multiple parts. Steps include placing a pattern in a tubular mold base, casting a ceramic member onto critical surfaces of the pattern, removing the pattern from the mold base, covering the critical surfaces transferred to the ceramic member with a powdered metal having a melting temperature greater than that of an infiltration metal, placing a quantity of an infiltration metal over the powdered metal, placing the tubular mold base in a furnace at a temperature sufficient to melt the infiltration metal without melting the powdered metal, and removing the ceramic member from the first open end of the tubular mold base to expose the critical surfaces. The quantity of the infiltration metal is sufficient to fill voids between the particles of the powdered metal when the infiltration metal is melted, thereby generating a fully dense metal part. The metal part has the critical surfaces transferred from the ceramic member when the infiltration metal solidifies. The metal powder also acts as a filter to filter out any contamination or oxidized metal within the infiltration metal so that such contamination does not blemish the finished surface of the fully dense metal part.

Title: Radio receiver for digital audio broadcasts including messages as well as radio programs
Inventor: WENDLAND ARND
IPC: H04H20/59
Filed: 1998-10-26
Granted: 2008-12-30
Abstract: The radio receiver (100) for digital radio broadcasts containing different message signal types has a loudspeaker output (16) and a message filter device (28) that passes or conveys only certain predetermined types of message signals to the loudspeaker output and interrupts a current state of the radio receiver (100) to make the preselected messages audible but suppresses the remaining types of message signals so that the current state of the radio receiver is not influenced by those latter signals. The message filter device has different states. These states in a preferred embodiment are designated only, for example, with "OFF", "ON" and "PS". "ON" means that the special message having this attribute is conveyed to the loudspeaker output through the filter device, i.e. the filter device is in the active state. "PS" expands the filter action, since only those programs are selected which contain message signals having this attribute when the program is changed, i.e. when the receiver is tuned to a new program. "OFF" indicates the state of the filter device is not active for message signals having this attribute, i.e. messages of this type are ignored and not passed through the filter device.

Abstract: A first mobile station (300A) within a particular service area is initially allocated (620) with a full-rate traffic channel. When congestion occurs within the serving base station controller (BSC) and no traffic channel is available for further allocation, the full-rate traffic channel previously allocated to the first mobile station is divided into two half-rate channels (650). The first mobile station is thereafter re-allocated (660) to one of the two half-rate channels by an int ra- cell handover (550) or mode modify procedure. The other half-rate traffic channel then becomes available to effectuate a new call connection with a second mobile station (300B) and increases the call capacity associated with the serving BSC.

Abstract: It is known in the case of wind power installations for them to be equipped with a synchronous generator and to provide an intermediate dc circuit and a pulse inverter on the output side thereof as a frequency converter for variable-speed operation of the synchronous generator.      Therefore the object of the invention is to provide a pulse inverter for a wind power installation, which avoids the above-mentioned disadvantages and overall reduces the power loss with a minimum content of harmonics.      According to the invention that is attained by a pulse inverter having the features of claim 1. An advantageous development is set forth in claim 2. Claim 3 sets forth a wind power installation with a pulse inverter according to one of claims 1 and 2. Claim 4 describes an arrangement of a plurality of wind power installations according to claim 3, which are connected in mutually parallel relationship.      The invention is based on the idea of moving completely away from a pulse inverter with a static switching frequency or pulse duty cycle, as is known from the state of the art and from Figure 2, and making the switching frequency variable, more specifically in dependence on the alternating current to be produced. In that respect, in the region of the passage-through-zero of the alternating current produced the switching frequency is at a maximum, that is to say the pulse duty cycle is at a minimum, while in the region of the maximum amplitudes of the alternating current the switching frequency is at a minimum, that is to say the pulse duty cycle is at a maximum.
