Title: Device for producing and adjusting an additional feed movement transversely to the longitudinal direction of the saw blade of a jigsaw
Inventor: LANGHOFF BORIS ING GRAD
IPC: B23D49/16
Filed: 1981-05-12
Abstract: A device for producing and adjusting an additional feed movement transversely to the longitudinal direction of the saw blade of a jigsaw (pendulum stroke adjustment), the feed movement being produced by means of a supporting roller acting on the back of the saw blade and rotatably mounted in a bell-crank lever, is to be configured more favourably with regard to the space requirement and the design effort and is to be improved with regard to the operational control. This is effected by virtue of the fact that, to set the pendulum stroke desired in each case, the distance of the free leg of the bell-crank lever carrying the supporting roller from the actuator can be varied by a vertically adjustable design of the bearing arrangement of the bell-crank lever. <IMAGE>

Patent DE-3201544-A1 (DE)
Inventor: SCHNEIDER RUDOLF
IPC: B23H1/08
Filed: 1982-01-20
Abstract: In swinging wire guides for generally conical finishing surfaces, the problem exists of a reliable automatic coaxial setting of the guide axes according to the particular angular position of the wire electrode in the workpiece finishing zone. As a solution, the wire guides (DF1, DF2) supported swinging on the support elements (TO1, TO2) are joined together by a coupling device, which has a guide member (FG) joined correspondingly with the support elements. The latter is set by the relative movement of the wire guides (DF1, DF2) to the desired angular position of the wire guides according to the ideal wire guide axis (D-D). Through swinging coupling gears (SK1, SK2) the angle position of the guide member (FG) is transmitted to the wire guides (DF1, DF2). These coupling gears suitably contain a jointed parallelogram (LK) and a rotary coupling member (DK) for the transmission of two swinging movement components, perpendicular to each other, in the sense of a total biaxial forced coupling of the guide member with the wire guides.

Title: Apparatus for the treatment of vessels having a liquid filling material, for example bottles
Inventor: SCHMIDT PAUL
IPC: B65B21/06
Filed: 1982-04-20
Abstract: To achieve the simplest and the most efficient working method of the machine, it is necessary that, firstly, the collecting boxes always stand under the bottle-receiving device during the insertion of the bottles, that, secondly, the bottom of this receiving device be divided into bottle-carrying plates pivotable downwards through 90 DEG and therefore be permeable, and that, thirdly, the bottle mouths be located between the gripper jaws after the bottles have been pushed onto the bottle-carrying plates. The operations which then follow and which are initiated accurately by means of a sequence control are as follows:   1. Closing of the gripper jaws and downward pivoting of the carrying plates.   2. Downward stroke and opening of the jaws. 3. Upward stroke and upward pivoting of the carrying plates, pushing in of the next bottle group.   The drawing (sheet 3) illustrates in principle a bottle-packaging machine for a double output. <IMAGE>

Title: Method and device for punching at least two mutually coaxial sheet-metal parts
Inventor: MITSCHELE WALTER ING GRAD
IPC: B21D28/22
Filed: 1982-05-14
Abstract: In a method for punching mutually coaxial sheet-metal parts, the sheet-metal parts are only partially separated from a strip-shaped sheet in a first punching operation and separated from it completely in a second punching operation. This makes possible efficient punching in high-speed progressive tools. The device for carrying out the method has two punching units for punching the coaxial sheet-metal parts. Their punches have a recess at the cutting edge. Provided after the punching units in the feed direction of the sheet there is in each case a further punch, the cutting edge of which is situated at least in the region of the recess, in relation to the associated punching unit. In the region of the recess, no cut is performed, with the result that the sheet-metal part is only partially separated from the sheet. It is only the following punch which separates the sheet-metal part completely from the sheet. The device makes possible efficient and economical punching of mutually coaxial sheet-metal parts.

Title: Process and device for widthways stretching of a dough strip raw piece
Inventor: LAITINEN REINO
IPC: A21C3/02
Filed: 1982-10-16
Abstract: A process for mechanical widthways stretching of a dough strip raw piece (1) transported by an endless cloth (2) along an essentially horizontal path with the help of a spiral roller and a device for carrying out the process. The aim of the invention is to replace the already known transverse rolling process and devices by a simpler process and a simpler device, by means of which the dough strip (1) can be given the desired transverse tension and width. It is characteristic of the process that the pressing means (4) is held separate from the dough strip raw piece (1) by a cloth (2, 2a) or the like running at the same speed as this dough strip raw piece (1), the speed of the spiral roller being independent of the transport speed of the dough strip raw piece. The device according to the invention is in turn characterised in that either the cloth (2) transporting the dough strip raw piece (1) or another cloth (2a) or the like moving at the same speed as the cloth (2) is passed between the pressure roller (4) and dough strip raw piece (1), the pressure roller, whose spiral-like projection on both sides of the centre part of the roller casing surface passes through roughly one turn about the roller, being able to be driven at a high rotary speed independently of the transport speed of the cloth (2, 2a). <IMAGE>
