  • Patent number: 11622503
    Abstract: A riding lawn mower has an internal combustion engine and a muffler with a first housing. The internal combustion engine is connected to the muffler to supply exhaust gases originating from the internal combustion engine to the first housing of the muffler for noise damping of the exhaust gases. A second housing is provided that thermally insulates the first housing of the muffler. The second housing at least partially encloses the first housing of the muffler. The second housing has an exterior side with an emissivity of greater than 0.8.

  • Patent number: 7958821
    Abstract: A printing unit of a printing machine is supported by a pair of spaced side frames that are disposed opposite to each other. The printing unit includes at least one printing machine and at least one ink unit. The printing machine is formed by a plurality of printing cylinders. Each of the spaced side frames include a longitudinal crossbar that runs in the direction of transfer of a print substrate traveling through the printing unit. The two longitudinal crossbars form the boundaries of a foot space of the printing unit at two parallel sides. A plurality of pipelines are disposed in the foot space between the two longitudinal crossbars. These pipelines supply flowable media to the printing unit, which flowable media can be either liquid or gaseous. At least one of the pipelines is connected to a user of one of the supplied flowable media in the printing unit or to at least one source of the flowable media. The printing machine can utilize a plurality of printing units.

  • Patent number: 7363905
    Abstract: Procedure to operate a combustion motor in the event of damage, whereby the thermoelectric voltage of a lubricant interruption on parts moving relative to each other and made of different, electrically conducting materials, is used to initiate an alarm signal, in that upon the appearance of such an alarm signal at least one operating parameter of the combustion engine is changed until the alarm extinguishes and the combustion motor is then further operated in a reduced operational state.

  • Patent number: 6820660
    Abstract: A device for filling bottles with liquid foodstuff in sterile conditions wherein an intermittently driven device is provided with bottle supports arranged successively in a line in the direction of conveyance and which passes through processing stations. The device is arranged in a hygienic chamber having through openings for the containers of the inlet and outlet thereof, including at least one inlet for introducing sterilizing medium in the upper wall of the hygienic chamber. Contiguous bottle supports form a closed area within the upper wall of the hygienic chamber and gas extraction systems are disposed in the vicinity of the bottle openings and on the outside of the hygienic chamber perform as dynamic sluice elements. The growth conditions for microorganisms in the hygienic chamber are hindered even in the event the amount of sterilizing agent is reduced.

  • Patent number: 6752258
    Abstract: Disclosed is a device for intermittently conveying packages which are conveyed in a first moving direction in package carriers (2) in a first processing plane in positions underneath various treatment stations and are conveyed back in a second return motion plane in a second moving direction that is parallel in relation to the first moving direction, whereby a conveying cycle is formed. The aim of the invention is to enable such a device to be efficient, compact and be operated using simple devices. According to the invention, the respectively superimposed ends of the essentially horizontal first conveyor (19) in the first processing plane and of the essentially horizontal third conveyor (12) in the second return motion plane are connected to one another for forming the conveying cycle by means of vertically acting second and fourth lifting conveyors (9, 15). Each conveyor (9, 19, 12, 15) has a separate drive (22-24).

  • Publication number: 20030075110
    Abstract: A milk meter suitable for measuring a quantity of milk flowing through the meter including: a sealed holding chamber (1); entry means (3) for admitting liquid to be measured into the holding chamber; a foam bypass chamber (3); sensing means (5, 7a) for sensing when milk is at or above a predetermined level in said foam bypass chamber, an inlet (13b) arranged to allow communication of milk between the holding chamber and the bypass chamber, the inlet being provided at a level below the predetermined level; drainage means (4, 8) associated with a timer, the drainage means being arranged to allow the milk to drain from the holding chamber for a set period of time (t) in response to a signal from the sensing means; and measuring means (11) arranged to count the number of times (n), milk has been drained from the holding chamber and to display the milk volume and/or flow rate.

  • Patent number: 5865221
    Abstract: A valve for filling liquids into packages has a housing (1) with a supply connection piece (24), a forward mouth piece and an outlet device (16) in which a large number of outlet holes (4) is arranged. A closing member (3) is movably arranged in the housing (1), and can be engaged with a valve seat (23). Rear sealing devices (5, 7, 22) are also provided. In order to make possible a high volume flow of the liquid contents at low outlet speed without relative movement occurring between the package and outlet device (16) it is provided that the outlet holes (4) distributed over the whole cross-section of the mouth piece (2) are arranged in an outlet plate (16) which is configured integrally with the mouthpiece, and penetrate it in the direction (26) of the longitudinal axis (28) of the mouth piece, that the diameter and the width of the outlet holes (4) is larger than 1 mm and smaller than 5 mm, and that the length of the outlet holes (4) is greater than double their diameter and their width.
