  • Patent number: 6360537
    Abstract: In a hydraulic vehicle drive which has a hydraulic circuit consisting of a variable displacement pump (2) and a hydraulic motor (10), the variable displacement pump (2) is driven by a diesel engine (1). During the braking or overrunning operation of the vehicle, the hydraulic motor becomes the pump and drives the variable displacement pump (2) which acts as a motor on the diesel engine (1) and attempts to accelerate the latter. The braking effect which is intended and obtained thereby involves the risk of the diesel engine (1) reaching impermissibly high rotational speeds. The braking therefore takes place in a controlled manner by a sequence valve (16) being arranged in the line (12) between the hydraulic motor (10) and the variable displacement pump (2). The sequence valve acts on the pivot angle of the variable displacement pump (2) via the pump bypass line (12B).

  • Patent number: 6361129
    Abstract: A wine rack and display shelf is adapted to cellar and display bottles of various shapes and sizes. The wine rack is capable of receiving and storing bottles in a generally horizontal position which has the benefit of preserving the moisture of the cork. The horizontal storage method is generally accepted as the most preferred method for long term storage. In addition, the wine rack and display shelf can also display and exhibit the bottles so that one selecting a bottle can view the label or other designations without the need to pull one of the horizontal bottles. This vertical display can also be used to allow the wine to breathe while maintained in the storage area where the environment is maintained at a preferred level.

  • Patent number: 6345483
    Abstract: A webbed reinforcing strip for poured concrete structures includes a first elongated tension strand, a second elongated tension strand spaced apart from and substantially parallel to the first tension strand, and at least two pairs of strands interconnecting the first and second tension strands in an open weave pattern. The interconnecting strands cross each other between the tension strands to form a webbed central portion of the strip. The interconnecting strands bend to join the tension strands at nonperpendicular angles at a plurality of nodes. All strands are formed of glass fiber reinforced plastic material and are bonded together with a bonding resin. Thus, thermal transfer and the potential for damage due to corrosion are minimized.

  • Patent number: 6339928
    Abstract: A loop flushing arrangement for controlling a closed circuit hydraulic propulsion drive. The variable displacement pump 12 is driven by a combustion engine 11. A flush valve 21 is used to clean and cool the hydraulic fluid in the closed hydraulic circuit. The flush valve is electrically operated and, as a result, permits novel and varied control options. The flush valve is controlled automatically, for example by a digital computer 1 as a function of the vehicle speed, the rotational speed of the combustion engine 11, or the temperature of the hydraulic fluid in the variable displacement pump 12. This results in the flushing procedure only being triggered and carried out if the operating state of the vehicle requires and permits it, i.e. when traveling at high speeds, for example.

  • Patent number: 6338247
    Abstract: A hydraulic vehicle drive, having a closed hydraulic circuit consists of a variable displacement pump and one or several hydraulic motors. The variable displacement pump is driven by a diesel engine. During the braking or pushing operation of the vehicle, the hydraulic motor becomes a pump and drives the variable displacement pump which, in turn, acts as a motor upon the diesel engine and acts to accelerate the latter. Thus, the intended braking effect prevents the danger that the diesel engine will reach non-permissible high revolutions per unit time, which is particularly dangerous for diesel engines with turbochargers. In order to prevent non-permissible high revolutions per unit time, a pressure regulator acting as a throttle is placed in the return line between the hydraulic motor and the variable displacement pump. The valve throttles the rate of flow when the pressure of the hydraulic fluid in the line exceeds a certain desired value during the braking operation.

  • Patent number: 6277018
    Abstract: An apparatus for producing and processing a strand of sausage or foodstuff has a sausage producing machine which produces a linked strand of sausage for deposit of loops of the strand on the hooks of a continuous conveyor. The conveyor picks up the loops of the strand at a loading station immediately adjacent the discharge end of the machine, and conveys the loops to a processing station for smoking or the like. The conveyor then moves the loops to an unloading station for removal of the strand from the conveyor, whereupon the conveyor downstream of the unloading station returns to the loading station to pick up additional product. A conveyor take-up mechanism is located immediately downstream from the loading station to permit the conveyor to cease movement at the loading station (while the casing on the machine is being replenished) while the conveyor can continue movement in the processing area. Sensors and controls interconnect the machine and the conveyor to coordinate the operational functions of each.
