Abstract: A guided cutting retainer for an elongated stack set is provided. During a cutting process of an end length of the stack set, the guide cutting retainer keeps end sides of layers of the stack neat and aligned. The guide cutting retainer includes a capped sleeve having a cross-section of a frame and formed with an internal longitudinal through opening. One end of the opening is combined to a U-shaped pedestal. A cut groove is reserved between the U-shaped pedestal and the opening. The U-shaped pedestal can be wedged and fastened with a pressing and positioning frame to provide a wedging effect. Thus, the pressing and positioning frame secures the stack set to fix its end side to form a complete blade-feeding guide groove for guiding the cutting process. The cutting process yields an aligned result further with intervention of a ruler board of an end sealing ruler.

Abstract: A coupling device for connecting a first coupling housing and a second coupling housing. The first coupling housing has a guiding element extending from the first coupling housing and having a free end at a distance (h) from the first coupling housing central axis (a-a). The second coupling housing has a receptacle for the guiding element and pull-in means for pulling the guiding element into the receptacle, said pull-in means being connected to the guiding element free end. The invention allows the first coupling housing to be pulled towards the receptacle at an angle which is not coincident with the central axis (a-a), and when the guiding element is in place inside the receptacle, the first coupling housing central axis (a-a) and the central axis (b-b) of the second coupling housing are aligned and coincident, and the two housings are rotationally aligned.

Abstract: Device and method for the mutual positioning of shell parts. Such shell parts can be used for constructing a large cylinder, for example a silo. The shell parts are provided with end flanges which extend at right angles thereto. Once the shell parts have been brought into the correct position, the end flanges are connected to one another in any suitable way. It is proposed to position the shell parts and/or end flanges with respect to one another in the desired position by arranging supporting rollers on the side where there are no end flanges. On the other side, clamping rollers are used which are at an angle to one another. A combination of in each case a supporting roller and a clamping roller provides both the correct mutual positioning of the shell parts with respect to one another and the pressing against one another of the shell parts.

Abstract: A preform clamping head which is mounted at the lower part of a heating chain (8) includes an integral annular sleeve body (1), the outer surface of which inclines outwardly from bottom to top and the upper part of which is provided with a retracting space (2) for the inward retracting of the annular sleeve body when it is pressed. The invention has simple manufacture process and low manufacture cost. By means of the integral molding mode, the axial requirement of the preform clamping head is easier to satisfy, so that the bottle preform clamped on the outer surface of the sleeve body is capable of rotating stably along the heating chain and can be heated more uniformly during the heating process.

Abstract: A device for moving store display cases or gondolas which are elevated above a support surface by support posts.

Abstract: A tire inflation cage includes a plurality of retention members that include spaced, substantially vertical upstanding members. The upstanding members are attached at their ends to a base and at a point along their outer surface to support members that extend at a substantially right angle from the base. The spaced retention members allow a tire assembly to be received therein and to be retained between a pair of tire stops for servicing of the tire. The substantially perpendicularly extending support members serve to increase the shear strength of the attachment of retention members to the base, thus preventing the retention member from separating from the base in the event that the tire assembly separates as it is being serviced in the inflation cage.
