20140169895 | PRECISION BORE MACHINE AND METHOD OF PRODUCING A PRECISE BORE - A bore machine for producing a very precise bore, as well as a method of producing a very precise bore in a workpiece. The bore machine has a main drive that drives the spindle rotationally as well as travel along the axial direction and an auxiliary drive that provides an oscillating motion in the axial direction that is overlayed over the forward travel motion of the spindle. The auxiliary drive has a first element with a wave-shaped surface and that is movable relative to a second element. During relative motion between the first and second elements, one element is forced to follow the peaks and valleys of the wave-shaped surface, thereby generating the oscillating motion. The auxiliary drive is driven such, that the relative motion between the two elements is at most 30% of the rotational speed of the spindle. | 06-19-2014 |

20100200156 | METHOD AND TOOL FOR PRODUCING A T-STRINGER - The present invention provides a method as well as a tool ( | 08-12-2010 |
20100314042 | METHOD FOR REINFORCING A FIBRE COMPOSITE COMPONENT AND A VACUUM MAT AND ARRANGEMENT FOR PRODUCING A REINFORCED FIBRE COMPOSITE COMPONENT - In a method for reinforcing a fibre composite component for aviation and space flight, a vacuum mat is configured with at least one receiving portion for reproducibly receiving at least one reinforcing element. The at least one reinforcing element is introduced into the at least one receiving portion of the vacuum mat. The vacuum mat with at least one introduced reinforcing element is applied reproducibly in a sealed manner to the fibre composite component to be reinforced to form a mould portion and at least the formed mould portion is cured to connect the at least one reinforcing element to the fibre composite component. The vacuum mat is then removed from the reinforced fibre composite component so that the vacuum mat can be reused. | 12-16-2010 |
20120152461 | METHOD FOR REINFORCING A FIBRE COMPOSITE COMPONENT AND A VACUUM MAT AND ARRANGEMENT FOR PRODUCING A REINFORCED FIBRE COMPOSITE COMPONENT - In a method for reinforcing a fibre composite component for aviation and space flight, a vacuum mat is configured with at least one receiving portion for reproducibly receiving at least one reinforcing element. The at least one reinforcing element is introduced into the at least one receiving portion of the vacuum mat. The vacuum mat with at least one introduced reinforcing element is applied reproducibly in a sealed manner to the fibre composite component to be reinforced to form a mould portion and at least the formed mould portion is cured to connect the at least one reinforcing element to the fibre composite component. The vacuum mat is then removed from the reinforced fibre composite component so that the vacuum mat can be reused. | 06-21-2012 |
20130175723 | method and a device for the preparation of a dry textile preform - A method for the preparation of a dry textile preform for a large surface area fibre-reinforced composite component, in which resin-free textile material layers for purposes of manufacturing the preform are tensioned in each case in a tensioning frame, and in the stretched state are laid down on a moulding body by means of a linear relative movement between the tensioning frame and the moulding body. Also disclosed is a device for the execution of a method of this type with a tensioning frame for purposes of tensioning the material layers, and with a clamping unit for purposes of fixing the laid-down material layers on a moulding body. | 07-11-2013 |

20100175218 | Vacuum Cleaner Accessory Valve - A vacuum cleaner having a base with a: nozzle opening, rear housing attached to the base, dirt separator with inlet and outlet passages, vacuum fan, accessory hose, and valve system to connect the separator alternately to the nozzle opening and hose. The valve system has a valve body having a first inlet connected to the nozzle opening and a second inlet connected to the hose, a hose connector that pivots with respect to the valve body, a connector passage through the hose connector, and a flexible outlet hose having a first end connected to the connector passage and a second end connected to the separator inlet passage. The valve inlets are generally equidistant from the connector pivot and the hose connector is pivotable to rotate the first hose end relative to the second hose end to selectively place the connector passage in communication with the first and second valve inlets. | 07-15-2010 |
20130031743 | Vacuum Cleaner sound reducing device - A vacuum cleaner is disclosed having a motor inlet conduit and sound deadening material disposed within the motor inlet conduit for reducing the overall noise level of the vacuum cleaner. The motor inlet conduit fluidly connects a dirt receptacle chamber and a motor inlet, and may have a generally continuous cross-sectional profile and one or more expanded regions for housing the sound deadening material. With the sound deadening material installed in the one or more expanded regions, the motor inlet conduit may form a smoothly changing profile along its entire length and reduce the overall noise level of the vacuum cleaner. | 02-07-2013 |
20140237749 | Flexible Mop Head - A wiping tool for arcuate surfaces is disclosed which includes a flexible base and at least one cover attached to the flexible base and a handle attached to the upper surface of the flexible base so that a lower arcuate surface of the flexible base may be aligned with an arcuate surface. | 08-28-2014 |
