Publication number: 20170197352Abstract: A method for the production of blow-molded containers that are sterile at least in certain regions, and a blow-molding machine configured to carry out the method. In accordance with the method, blowing stations are arranged on a rotating blowing wheel. A preform of a thermoplastic material is first heated and then stretched in a blowing station by a stretching rod and subjected to a pressurized blowing fluid via a blowing nozzle. A sterilizing fluid is supplied to the preform in the blowing station to perform a sterilization. The sterilizing fluid is fed into the preform from an outlet and is carried away again via an inlet and in between follows a flow path. The sterilizing fluid is made to pass through or pass by the stretching rod on its flow path, and the sterilizing fluid is supplied while the blow-molding machine continues to operate.Type: ApplicationFiled: June 23, 2015Publication date: July 13, 2017Applicant: KHS Corpoplast GmbHInventors: Michael LITZENBERG, Martin GERHARDS, Thomas HEROLD, Dieter KLATT

Patent number: 9389156Abstract: The invention relates to a method for determining the soil stiffness (kB) of a soil area (2). For this purpose, a vibration-excited contact body (6, 8) of a soil compacting device (1) acts upon the soil surface (9) in such a way that during the acting upon an unsteady loss of contact (jumping) between the soil surface (9) and the contact body (6, 8) occurs. While acting upon the soil surface, parameters (f) of the oscillation excitation and parameters ({umlaut over (x)}d) of the oscillation response (xd) of the contact body (6, 8) are determined and from these in combination with known parameters (mu, ru, md) of the soil compacting device (1) the soil stiffness (kB) is computed.Type: GrantFiled: October 13, 2010Date of Patent: July 12, 2016Assignee: Ammann Schweiz AGInventors: Roland Anderegg, Martin Gerhard, Kuno Kaufmann

Patent number: 6345686Abstract: The drive assembly is formed by an internal-combustion engine which is installed in a passenger car. By means of bearings, supports or the like, the internal-combustion engine is held in position in an assembly space. By means of a wall of a vehicle body, the assembly space is separated from a vehicle occupant compartment. For achieving favorable psycho-acoustic effects, a sound support is provided between the internal-combustion engine and the wall of the vehicle body, by which sound support the engine-mechanical structure-borne sound is transmitted into the vehicle body, specifically for a targeted perception by occupants in the vehicle occupant compartment.Type: GrantFiled: April 7, 2000Date of Patent: February 12, 2002Assignee: Dr. Ing. h.c.F.

Patent number: 6223206Abstract: A method and system for improving load balancing in a file server is disclosed. The method includes determining the existence of an overload condition on a storage device, the storage device having a plurality of retrieval streams accessing at least one file thereon; selecting a first retrieval stream reading a file; replicating a portion of said file being read by said first retrieval stream onto a second storage device; and reading the replicated portion of said file on said second storage device with a retrieval stream capable of accessing the replicated portion of said file. The method and system enables the dynamic replication of data objects to respond to fluctuating user demand. The method and system is particularly useful in file servers such as multimedia servers delivering continuously in real time large multimedia files such as movies.Type: GrantFiled: August 28, 1998Date of Patent: April 24, 2001Assignee: International Business Machines CorporationInventors: Asit Dan, Martin Gerhard Kienzle, Dinkar Sitaram, Philip Shi-lung Yu

Patent number: 5940840Abstract: An improved method for supporting an empirical measurement of the data bandwidth that one or more computer disks can continuously sustain while reading data. In a computer system having predetermined workload requirements and disk storage for storing an allocation table including entries for meta blocks and data blocks, a method for supporting a dynamic measurement of the read bandwidth of a disk, includes the steps of: creating an alternate allocation table that ignores the existing content of the disk; creating meta blocks for a phantom file by allocating the meta blocks from the allocation table; allocating data blocks for the phantom file from the alternate allocation table; and writing only meta blocks to the disk, but not actual data blocks. Since the actual data blocks are by far the largest component of the files, phantom files require only a very small number of disk blocks, and can be written very quickly.Type: GrantFiled: May 20, 1997Date of Patent: August 17, 1999Assignee: International Business Machines CorporationInventors: Marc Eshel, Martin Gerhard Kienzle, Daniel Lloyd McNabb, Raymond Edward Rose, Frank Bernhard Schmuck
