Abstract: A tarp cover system includes a plurality of bows that extend transversely across an open-topped vehicle-mounted container for supporting a tarp cover, characterized in that the drive system for driving the bows between container-covered and container-uncovered conditions includes at each side of the container an endless cable arrangement including a pair of parallel horizontally-spaced runs that are contained in a common horizontal plane and are arranged on opposite sides of a longitudinally extending support upon which the bows are slidably mounted.  Protective flanges extend laterally from the support above the cable runs, thereby to protect the cable runs during loading and unloading of the container.  The side edges of the tarp extend horizontally outwardly over the cable runs and downwardly adjacent the external sides of the container, thereby to waterproof and protect the upper side edges of the covered container against the entry of water and dirt.

Title: Precombustion chamber device
Inventor: KUHNERT DIETER
IPC: F02B19/12
Filed: 1995-03-13
Granted: 2004-10-12
Abstract: A precombustion chamber ignition device for preferably lean fuel-air mixtures and having a precombustion chamber. This precombustion chamber contains a electrode carrier extending into the precombustion chamber and on it at least one ignition electrode is attached, which has at least one ignition portion, which cooperates with a internal wall surface of the precombustion chamber in defining at least one spark gap extending substantially athwart the longitudinal axis of the precombustion chamber. In this respect the internal wall surface acts as a ground electrode. The ignition portion of the at least one ignition electrode is offset in relation to the longitudinal axis of the precombustion chamber and is arranged essentially parallel to the wall surface, which is substantially cylindrical in the spark gap portion, of the precombustion chamber close to the wall surface. In consequence it is possible for the ignition potential to be reduced and in the case of long term operation for the working life of the precombustion chamber ignition device to be in-creased. More particularly however the reliability of flaming is a substantially improved in the case of diluted fuel-air mixtures (lean mixtures, recycled exhaust gas).

Granted: 2000-05-02
Abstract: A sliding door (10) having a sliding panel (12) is horizontally displaceable via wheels (17) between open and closed positions in an associated frame (13). In the closed position the sliding panel is sealable via sealing elements (18) against the frame (13) and an adjacent support panel (11). The sliding panel (12) is displaceable sideways from a stable sliding position towards an unstable support position with a combined, forcibly guided sliding movement and barring movement and from an unstable support position to a stable sliding position by means of the weight of the sliding panel. A stop means (30) forcibly guides the sliding panel (12) from sliding position towards support position and bars the sliding panel in a sealing-forming support position. The stop means permits automatic readjustment of the sliding panel from unstable support position to sliding position immediately the barring engagement is removed.

Granted: 2002-11-12
Abstract: The invention encompasses methods of introducing biologically active peptide s into a host (particularly for vaccination or transitor y expression of a therapeutic peptide) or administration of polynucleotides wh ich operatively encode for the peptide. In most embodime nts, the polynucleotides are naked in the sense that they are neither complexed t o colloidal preparations such as liposomes or associated  with a genomic integrating vector. In one embodiment, the naked polynucleotides are  administered to host tissues which have a high concentr ation of antigen presenting cells in them relative to other host tissues. It is be lieved that the polynucleotides are taken up and express ed locally, systemically and/or at locations remote from their point of entry i n the host. In another embodiment, the polynucleotides e xpress peptides which are effective in retarding, treating and preventing age-assoc iated illnesses and loss of disease resistance in mammal s. In this embodiment, subtherapeutic levels of the peptides are expressed at appropria te stages of the host's development. Devices and composi tions for use in the methods of the invention are also described.

Granted: 2005-12-20
Abstract: A method and apparatus for producing a temperature stabilized frequency from a signal generator in a monitoring station is described. The signal generator monitors the voltage response of an RC circuit where the resistive portion is formed by a thermistor, to produce a time-dependent signal. A comparator compares the time-dependent signal to a reference voltage to determine a rise time of the voltage across the capacitor. Based upon a software timer loop, the signal generator determines a temperature range by selecting data from a look-up table based upon the rise time of the RC circuit.
