Title: Planar linear pulse motor
Inventor: MAEDA TETSUO
IPC: H02K41/03
Filed: 1986-12-05
Granted: 1991-05-14
Abstract: ABSTRACT OF THE DISCLOSURE     In this planar linear pulse motor, first and second assemblies are mutually movable along an axial line. The first assembly includes a group of teeth which are arranged at a determinate pitch in a row along a line parallel to this axial line, each of these teeth being elongated in a direction perpendicular to the axial line. The second assembly includes four groups of teeth, each such group being arranged at the same determinate pitch also in a row along a line parallel to the axial line, with the phases of the four groups of teeth being offset from one another, and with each of these teeth also being elongated in a direction perpendicular to the axial line. The four groups of teeth of this second assembly each confront the group of teeth of the first assembly in parallel and are separated from those teeth by a relatively small gap. One of a pair of magnetic core members is contiguous to one side surface of a permanent magnet which has opposite magnetic poles on its side surfaces on either side of its central longitudinal line, and the other of this pair of magnetic core members is contiguous to the other magnetic pole side surface of this permanent magnet. Each of these magnetic core members has two pole surfaces contiguous to two of the four groups of teeth of this second assembly. For each of the magnetic core members, there is provided a coil for inducing magnetic flux in it.

Title: Method and a device for tightness control of a joint
Inventor: LARSSON LENNART
IPC: G01M3/38
Filed: 1987-11-26
Granted: 1991-04-02
Abstract: Abstract of the disclosure A method and a device for the control of a joint between a first element and a second element. The first element preferably is an end element of a container and is inserted in an opening in said container such that a rim is formed around the opening and includes a joint.            The rim allows the placement of a radiation or wave energy transmitting source at one side thereof and a detector device at the other side. The radiation or wave energy  source has a capacity of penetrating, preferably fully, the rim and illu-minating said rim by a small dot, which is scanned crosswise the width of the joint by a scanner device.            The container is rotated around an axis and the detector device registers the characteristics of the radiation that passes the joint and/or is reflected at the joint and which originates from a repeated  "point illumination of the joint". By placing the detector device at a sufficient distance from the rim there is obtained a magnifying effect in the detector, which allows the detection of very small changes in the quality of the joint.            The method and the device are especially suited for joints comprising substantially plastics material and where the pro-duct, which may affect the joint also substantially consists of an organic material, for instance a food product.

Abstract: Abstract:           (In conjunction with Figure 1) In the production of packs for stacks (10) of paper handkerchiefs, the problem is to give the cuboid pack an exact shape.  When a stack of paper handkerchiefs is pushed into a pocket (13) of a folding turret (12), the stack (10) is compressed by a press plate (22) movable up and down in the peripheral direction of the folding turret (12) and, in this compressed form, is pushed into the pocket (13) to-gether with a blank (11).  On the opposite side of the fold-ing turret, the virtually finished pack is pushed in the radial direction out of the pocket (13) and onto a push-out platform (48) which moves up and down along the periphery of the folding turret and which is temporarily, in particu-lar during the reception of the pack, in synchronism with the folding turret (12).  During a standstill phase of the push-out platform, the pack is transferred from the latter to a discharge conveyor (49).
