Abstract: A test switch for use in electrical power distribution networks is provided. The test switch facilitates the connection between the power distribution networks' equipment and test equipment used to effect tests on the power distribution networks' equipment. The test switch has a solidifying base which decouples the fastening of the body of the switch to the base of the test switch from the fastening of the test switch on an external surface/equipment. Various locking mechanisms for preventing use of or tampering with the test switch are also provided.

Abstract: The present invention discloses a multifunctional carrying device comprising a female connecting member and a male connecting member which the female connecting member and the male connecting member are connected in a snap-in manner; either the male connecting member or the female connecting member being fixed on a bag. The multifunctional carrying device of this invention can be used on both horizontal direction and vertical direction, not just simply adding a bag, but it could change from one application to another application, so as to increase the utility. This invention could be dismantled and saves space, basically it will not increase the weight of the bag and convenient in using.

Abstract: The present invention discloses a material of storage device, a storage device and a bag of the same. The material of storage device comprise a composite layer composed of polyurethane layer, polyurethane-polyurea copolymer layer, ethylene-vinyl acetate copolymer layer materials. The storage device is formed by the above material, which can be folded in vertical direction and/or horizontal direction; the storage device has a plurality of cavity-shaped storage chamber. A bag formed by the storage device is disclosed. The material and structure of the present invention has the features of waterproof, light weight, proper hardness, capability to fold, high wearing feature, scratch resistant. The storing spatial pattern of the said storage device could be adjusted when needed; it could effectively protect the stored items. The provided bag could be opened partially, allowing quickly and conveniently access to the stored items, the storage space in the bag is designed for a better protection of stored items.

Abstract: The method makes it possible to form a stator of an electric motor by means of a multiple-slide press (21, 22, 23). The starting point is a bundle consisting of rectilinear segments of sheets obtained by stamping and welded. The stator is formed by means of four successive operations carried out by four groups of slides of a multiple-slide press and corresponding dies. The cylinder formed is subsequently welded along its joining generatrix and is calibrated in a hydraulic press.

Abstract: For marking a field with unseeded rows during seeding, the seed box of a seed drill is equipped with a valve unit mounted inside the box for shutting off seed flow to one of the seed cups during selective passes. A control system for the unit allows the shut-off to be automatic, after a selective number of passes have been completed, or manual as selected by the operator. The unseeded rows are used after germination for guiding a crop sprayer so that there will be no spray overlap and no gaps between the sprayer passes.
