Patent SE-7712207-L (SE)
IPC: B65B25/02
Filed: 1977-10-28
Abstract: Two superimposed layers of thermally weldable material are welded to one another at welding zones delimiting respective receptacle preforms having respective open ends and connected in series to a transporting strip which extends longitudinally of the processing path of displacement of the receptacle preforms. The goods to be packaged are introduced into the respective receptacle after the two layers of the respective receptacle preform have been separated by blowing a stream of air into the receptacle through the open end thereof. Thereafter, the open end of the receptacle preform is closed and the receptacle preform is severed from the transporting strip to obtain a filled receptacle which is freely transportable. The welding operation is performed by a welding roller which has an electrically resistive conductor wire mounted thereon along such a course that, when developed into the plane of the superimposed layers, the conductor wire will coincide with the zones to be welded. A severing arrangement which cuts through the superimposed layers to obtain openings in the receptacles is displaced by an eccentric portion of the welding roller in a predetermined sequence with the welding operation.

Abstract: The invention refers to a target for an electronic target marking device. The board has a target area (A), a reference potential level (B) and a correction level (C), all of which consist of an electronic conducting material, e.g. an electrical conducting rubber cloth. Between the levels there is a layer (5) of electrically insulated material. The target layer is divided into different target areas (1, 2, 3) each with connection conductors (6, 7, 8). Each target area (1, 2), surrounding the other target areas (2, 3) is formed with open sections (11, 12) crossed by connection conductors (7, 8) from the area within. The correction level (C) is divided into parts (14, 15) that cover the open sections making it possible though logical deduction to correctly and unequivocally indicate hits in those ring areas crossed by connection leads from the areas also within the ring area.<IMAGE>

Abstract: In a polyphase machine, being either a motor or a generator, there is provided a stator core having main stator windings and control windings. In the example of a squirrel cage induction motor these windings are wound about the stator core and the main windings have a capacitor connected in series with each such winding. In a three phase motor the control windings wound on the stator have currents in each phase which are substantially in phase at no load with the currents of the corresponding radially adjacent the main windings. Such currents become out of phase with their main winding currents as the load increases. The control windings are wound in an opposite sense to the corresponding main windings such that at low load the net flux density is low and as the load increases the flux density increases. Increase of starting and breakdown torque is achieved by having the respective poles created by the main windings and those created by the control windings placed to create a force because of the symmetry of the magnetic field. In this case the centers of the poles of the control windings are placed as close as physically possible between the poles of the main windings, thereby improving the magnetic centering of the poles. The voltage across the capacitor added to the input voltage may cause the stator core to switch periodically between non-saturated and saturated conditions.

Abstract: The stacking device comprises an upwardly open fixture to accommodate a pipe layer coming from the forward feed transporter. The fixture consists of five of the sides for achieving a hexagonal formation which can be raised or lowered. After a pipe layer has been placed in the fixture, it drops by a stage corresp. to the thickness of the pipe layer. The fixture also partly comprises a transfer finger which, independently of the raising and lowering movements of the fixture, moves parallel to its bottom side to a bridging location for transfer of pipe layers from the transporter. At least the fixture side which, in the effective position, faces away from the forward feed transporter is free-standing in relation to the fixture. After positioning of the most central layer of the hexagonal bundle is movable from a drawn-downwards position to its effective position, in which its width increases in time with the lowering of the fixture.

Abstract: The invention relates to a contact arrangement designed as a catch connector and primarily intended for use in withdrawable apparatus for locking the plug-in contacts of the apparatus in the operating position when a short-circuit current flows through the apparatus. The arrangement comprises two contact members (40, 50) which are displaceabe in relation to each other, as well as a plug-in contact device (16) which is supported by the first contact member (40) and is insertable into the second contact member (50). The two contact members (40, 50) each have two contact surfaces (43, 44 and 54, 55, respectively) facing each other. The contact device (16) comprises two cooperating elongated contact members (20, 30) with transversally projecting end portions. The two contact members form two electrically parallel-connected current paths between the two contact members. At the two end portions of the contact device, the current paths intersect each other, whereas in a relatively long middle portion of the contact device the current paths are parallel to each other thus generating an electrodynamic contact pressure reinforcement. The above-mentioned second contact member (50) has two parallel and each other opposing legs, each of which exhibits a tongue (51) which is arranged inside a locking strip (53) formed by the free end portion of the leg. Each tongue forms a contact surface for cooperation with the plug-in contact device (16). Upon a short circuit, current forces are generated which attract the two contact members (20, 30) of the contact device towards each other and force the end portions of the contact members in behind the locking strips (53), thus preventing contact separation. <IMAGE>   <IMAGE>
