An ice fishing sled includes a base, a plurality of side walls, a crossbar, and a seat. The base has a length and a width. The plurality of side walls are connected to the base, and extend generally normal to the base. The plurality of side walls include opposing side wall portions and opposing end wall portions. The crossbar is supported by the opposing end wall portions, and is positioned intermediate the opposing side wall portions. The seat is supported by the crossbar and a first one of the opposing side wall portions. Further disclosed is a method of connecting a wear strip to a sled.

A portable shelter comprises a sled, a first bracket, a first pole, and a first sheet of material. The sled includes a base and a plurality of walls connected to the base, and the plurality of walls include a perimeter edge. The first bracket is disposed on the sled. The first pole has a first end and a second end, where the first end of the first pole is operatively connected to the first bracket. The first pole is pivotable between a first position where the second end of the first pole is positioned adjacent to a first portion of the perimeter edge and a second position where the second end of the first pole is spaced from the first portion of the perimeter edge. The first sheet of material is secured between the first pole and the portion of the perimeter edge of the sled, such that the sled can be positioned to rest on a bottom edge of the edge portion with the sled tilted at an angle defined by the first sheet. Further disclosed is a method of converting a shelter assembly between a sled mode and a shelter mode.

A portable shelter system is constructed from two portable shelters. Each portable shelter is provided with an enclosure having a front wall configured with a door and a rear wall configured with an opening. The opening of each rear wall is fitted with first and second zippers about the perimeter of the opening. A second door fitted with a mating zipper is reversibly connected to the first zipper. A sleeve having opposing first and second perimeter edges is fitted with mating zippers that connect to the second zippers of each opening when the rear walls of the two portable shelters are adjacent to and spaced from one another.

A drive unit is in working connection with a power takeoff by way of a wrap spring, which has a predetermined number of turns between its two ends and which serves as a load torque interlock. The wrap spring has a first actuating area assigned to a selected direction of rotation on at least one of its two ends and a second actuating area assigned to the opposite direction of rotation, where the first actuating area can be brought into nonrotatable working connection with the drive unit and the second actuating area into nonrotatable working connection with the power takeoff. By the application of a drive torque produced by the drive unit on the first actuating area, a first change in the diameter of the turns in the direction away from a braking device can be obtained, with the result that the frictional connection between the turns and the braking device is at least weakened. By the absorption of a restoring torque which originates from the power takeoff and acts in the opposite direction of rotation on the second actuating area after the drive has been turned off, a second change in the diameter of the turns in the direction toward the braking device can be obtained, with the result that the frictional connection between the turns and the braking device is increased.
摘要:
A device for isolating nucleic acids which reduces the transfer of contaminants during nucleic acid isolation methods which is composed of two vessels which are linked by a closing element in which a material that binds nucleic acids is placed. The nucleic acid can for example be bound to the material by tipping the device.

A process for producing a veneer is disclosed wherein a layer made from a polyolefin, a copolymeric polyolefin or both is applied to a veneer sheet using heat and/or pressure. A veneer produced using this process is also disclosed.
摘要:
System and process for isolating purified biological materials with a collecting unit which has collecting vessels that are accessible from above with a matrix unit in which matrix vessels are arranged in a holder as well as a closure unit which can be placed on the collecting unit to close the collecting vessel. In addition the invention also concerns a system having a collecting unit, a matrix unit, and a closure unit as well as a lysis unit and a waste unit. Moreover a new closure arrangement is disclosed which is suitable for closing vessels in which there is excess pressure.
