Abstract: Embodiments provide systems, methods, and masking workstations for masking a planar substrate with a shield. The shield is configured to facilitate the removal of a waste portion of masking material from a portion of a planar substrate. In some cases the shield is placed adjacent to a substrate and a masking material is applied to the substrate and at least a portion of the shield. A waste portion is separated from the masking material and the shield removes the waste portion. Embodiments can be useful for masking only a portion of a planar substrate, including glass panes and glass units, for example.

Abstract: Methods for manufacturing insulating glass units (IGUs) include providing an unsealed IGU assembly that has first and second sheets of glass material and at least one spacer frame between the first and second sheets and sealed to at least one of the first and second sheets. The unsealed IGU assembly defines an interpane space and an IGU passage providing fluid communication between the interpane space and an environment external to the interpane space. In some cases the method includes positioning a filling device next to the IGU passage and introducing a gas into the interpane space through the IGU passage using the filling device. In some cases the method includes delivering a sealing material or sealing structure to the IGU passage with the filling device to seal the interpane space. Corresponding systems for manufacturing IGUs are also provided.

Abstract: A method for filling an unsealed insulating glass unit (IGU) includes providing an IGU assembly on a support structure and between a first plate and a second plate. The unsealed IGU assembly has a spacer frame between first and second sheets, thus defining an interpane space and an IGU passage that provides fluid communication between the interpane space and an ambient environment. The method also includes pressing the unsealed IGU assembly against the second plate with the first plate while pulling a first vacuum on the first sheet with the first plate and pulling a second vacuum on the second sheet with the second plate. The method also includes evacuating air from the interpane space through the IGU passage and introducing a gas into the interpane space through the IGU passage. A gas filling system having similar attributes is also provided.

Abstract: Embodiments include a method for replacing air with an interpane gas during manufacture of a sealed insulating glass unit (IGU). The method includes forming an unsealed IGU assembly defining an IGU passage for fluid communication between an interpane space and an ambient environment. The method can include moving components of the unsealed IGU assembly into an enclosure and assembling the components to form the unsealed IGU assembly within the vacuum enclosure. The method can also include sealing the enclosure around the unsealed IGU assembly; evacuating air from the enclosure; and introducing a first gas into the interpane space through the IGU passage. The method can also include introducing a second gas into the enclosure, wherein the second gas has a different composition than the first gas; and closing the IGU passage to seal the interpane space. Other embodiments are also included herein.

Abstract: An embodiment provides a crossbow, comprising a stock and a bow portion. The stock comprises a first portion and a second portion. The first portion comprises a string latch and extends from a rear end to a coupling end. The second portion extends from a coupling end to a front end. The bow portion comprises a riser assembly, a first limb coupled to the riser assembly, a second limb coupled to the riser assembly; and a drawstring extending from a distal end of the first limb to a distal end of the second limb. The bow portion is coupled to the second portion of the stock. The coupling end of the first portion of the stock is detachably coupled to the coupling end of the second portion of the stock at a coupling location. The coupling location is between the string latch and the drawstring in an undrawn position.
