摘要:
A process for producing precondensates of partially crystalline or amorphous, thermoplastically processable, partially aromatic polyamides or copolyamides, and the use of the higher molecular weight of polyamides, accessible from the precondensates, for producing molding compositions, which are further processable by means of suitable processing techniques, involves the control of temperature and water vapor partial pressure, in a batch process.

A device for sterilizing containers includes a first treatment space, which is filled with a sterilizing gaseous medium under predetermined thermodynamic conditions, a tank, which is filled with a liquid medium and extends along a closed path, and a multiplicity of holding devices for holding the containers. The holding devices are arranged rotatably with respect to the treatment space, and a dividing wall, which protrudes into the liquid medium located in the tank is arranged rotatably with respect to the tank. A discharge opening, via which the gaseous medium can be discharged, is provided between the treatment space and the tank.

An apparatus (1) for filling containers (6) with a liquid and, in particular, with a beverage, with a plurality of filling elements (5) which in each case have an outlet (37) in order to pour the beverage into the containers (10), as well as a valve device (38) in order to control the supply of the liquid into the containers (6), with a conveying device which conveys the containers (10) along a pre-set conveying path at least for a time during the filling thereof with the liquid, and with a cleaning device which acts with a cleaning medium upon at least one region contacted by the liquid to be filled. According to the invention at least one filling element (5) is designed in such a way that the cleaning medium is freely discharged out of this filling element (5) during a cleaning operation.
摘要:
A method and apparatus of producing tubes for use in a heat exchanger, in which a tube is moved along a production line in a direction, predetermined breaking points are created in the tube, and in which the tube is severed at the predetermined breaking points to form individual tubes with a tearing-off device having a first clamp and a second clamp. The first clamp can be reciprocated along the direction, and the tube can be moved substantially continuously along the production line in the direction through the tearing-off device. Also, the second clamp can be reciprocated along the direction substantially simultaneously with the first clamp.
摘要:
An apparatus for transporting objects and in particular containers, having a first conveyor which transports the objects along a specified transport path (P), including a sterile room, within which the objects are transported, and including a second conveyor which follows on from the first conveyor. According to the invention, the first conveyor is positioned completely inside of the sterile room and the second conveyor is positioned completely outside of the sterile room, wherein both the first conveyor and the second conveyor are preferably positioned in a specified transitional area (B) along the transport path (P).
摘要:
The invention relates to a reflector system for positioning a medical instrument or of body parts of a patient or for any determination of position, which is characterized by reflectors (3, 4, 5) that are configured as transparent retroreflective spheres and may consist of a material with a refractive index of preferably 1.9.
摘要:
A device for feeding a pulp suspension to a tissue machine includes a headbox having top and bottom lips defining a slice gap forming a free flow jet of the pulp suspension. The device also includes at least one eccentric shaft for setting the slice gap between a minimum and a maximum height. Each eccentric shaft is supported at several points over the machine width and is driven directly by a gear motor.

An extruder forms shaped bodies from plastics-filler mixtures having a filler content of more than 50% by volume. The extruder comprises a product feed device, an outer mouthpiece and two barrels arranged coaxially between the product feed device and the outer mouthpiece. The first barrel (input cone) having an inside wall provided with grooves essentially parallel to the longitudinal extent of the barrel is connected with the product feed device. The second barrel (output zone) is connected with the outer mouthpiece. A screw arranged in the first barrel conveys material into the second barrel. Separate tempering arrangements for the first barrel, for the second barrel and for the mouthpiece control the desired operation temperatures in the extruder. Preferably, the extruder additionally includes a mandrel connected with the screw and arranged in the second barrel.
摘要:
A gas bag arrangement for a vehicle occupant restraint system of a motor vehicle. The gas bag arrangement comprising a gas bag package which includes a folded gas bag and a wrapping which at least partly surrounds the folded gas bag, at least one connecting strap for connecting the gas bag to a holding structure of the motor vehicle, wherein the connecting strap is attached to a fastening portion of the gas bag and a deflection device arranged at the wrapping or formed by the wrapping, at which the connecting strap—relative to the condition of the gas bag arrangement as mounted in the vehicle—is deflected in direction of the holding structure. A section of the connecting strap coming from the fastening portion extends up to the deflection device away from the holding structure and at the deflection device again is deflected towards the holding structure.
摘要:
An apparatus for heat shielding and deceleration of a spacecraft comprises an unfoldable shield of individual panels made of a high temperature resistant fiber reinforced ceramic and pivotally mounted on the outer structure of the spacecraft. An unfolding ring slides axially along the body of the spacecraft. The panels are pivotally connected to the unfolding ring by compression struts acting as toggle levers. Tension springs pull the unfolding ring axially along the spacecraft body to toggle out the compression struts so as to outwardly pivotally deploy the panels. The unfoldable shield can be arranged on the forward end or the rear end of the spacecraft relative to its flight direction upon entry into the atmosphere.
