Abstract: A clamping device (1), particularly a machine vice (1), has a body element (2), a jaw (3) attached thereto, and an oppositely placed movable jaw, for displacement by a drawbar (4). The drawbar has a compression bar to be arrested at varying distances from the fixed jaw, and a force amplifying arrangement (5) acting on the spindle. The force amplifying arrangement includes at least one cylindrical tube (9) and at least two plungers (10, 11) that are movable in concentric cylinders. Two compression chambers are provided, an outer, low-pressure chamber (12) and a high-pressure chamber (14) acting on the clamping plunger (11) from the direction of the drawbar, wherein a functional connection is established between the two plungers so that at least one rod (18) having a smaller diameter than the diameter of the plungers and connected to the outer compression plunger (10) acts on the high-pressure chamber (14), which is filled with pressurising medium, preferably oil or liquid grease.

Abstract: In order to obtain a simple, inexpensive and low-maintenance monitoring device for controlling the setting width of individual teeth of saw blades or belt-saw blades, in particular for controlling the setting result of a setting machine the present invention invisages that the monitoring device comprises at least one photo-detector whose light beam at least partly runs through one or both regions laterally next to the running-past saw blade or belt-saw blade, into said regions the set teeth project.

Abstract: The invention relates to a clamping device (1), particularly a machine vice (1), having a body element (2), a jaw (3) immovably attached thereto, and an oppositely placed movable jaw, for the displacement of which a drawbar (4) is provided, wherein the drawbar (4) is furnished with a bearing member on which the movable jaw is supported by means of a compression bar, and the movable bar is configured so that it may be arrested with the compression bar at varying distances from the fixed jaw, and a force amplifying arrangement (5) acting on the spindle is provided. The object of the present invention is to describe a clamping device that is as compactly configured as possible.

Abstract: The invention relates to a device for setting saw blades or belt-saw blades with clamping jaws arranged on both sides of the saw blade or belt-saw blade and with setting tools arranged on both sides and pivotable about an imaginary axis. It is the object of the invention to put forward a new device with which the setting result may be improved. According to the invention the object is achieved in that in horizontally displaceably mounted guiding blocks arranged on both sides of the saw blade or belt-saw blade there is pivotably mounted in each case a setting tool mounting formed as circle segment, wherein the guiding block is designed simultaneously as a clamping jaw for fixing the saw blade or belt-saw blade, and that displacement devices are provided for the horizontal displacement of the guiding blocks.

Abstract: The invention relates to a device for the advance of a belt-saw blade by a setting width of a setting machine. In order to prevent damage on the tooth face and the cutter of belt-saw blades, the advance is effected by a roller drive, wherein the belt-saw blade is arranged with a friction fit between a roller and a counter roller and the roller drive comprises a path measurement device.

Abstract: An arrangement for coating an object with water soluble or water dilutable coating materials during a spraying process, has an elongated collecting wall adjacent the object to be sprayed located in a coating region, a collection member connected to a lower portion of the wall, a unit for at least partially cooling the the wall and the collection member located in the coating region, and at least one air moisturizing unit located in the coating region.

Abstract: Successive plate-like substrates are transported in a horizontal plane on a first conveyor beneath a first spray coating device on their way toward an inverting device which turns successive substrates through 180.degree. and deposits them on the supporting elements of a second conveyor which advances the once coated substrates beneath a second spray coating device. The twice coated substrates are advanced through a drying zone wherein they are acted upon at both sides by infrared heaters which expel the surplus of moisture. The supporting elements are in mere linear or point contact with the coated undersides of inverted substrates above the second conveyor. Such supporting elements can engage uncoated marginal portions of the substrates or the coated portions of undersides of substrates above the second conveyor. Coating material which bypasses the substrates is intercepted and collected, and the supporting elements are cleaned at regular intervals.

Abstract: Apparatus for electrostatic spray coating of plate-like substrates, particularly printed circuit boards, has one or more endless conveyors or one or more conveyors of finite length with one or two pairs of strip-shaped holding elements for the edges of substrates. The holding elements engage a substantial part or the entire edge of the substrate which is transported through one or more spray coating stations. Each holding element is made of or contains an electrically conductive material, and the holding elements are grounded, at least during travel through the coating station or stations. The holding elements can engage the edges of substrates by friction or they are coated with an adhesive so that they adhere to the edges of the substrates.

Abstract: Apparatus for spray coating plate-like or otherwise configurated workpieces has an endless apertured conveyor which transports a series of workpieces along a horizontal path beneath a rotary atomizer which sprays coating material onto the advancing workpieces. The coating material which bypasses the workpices and passes through the apertures of the conveyor impinges upon and gathers on a web of paper or non-woven fibrous material which is advanced at a speed less than the speed of the conveyor so that the web can be used with great economy because it is or can be advanced at a rate such that, or only when, its portion which is in the path of sprayed coating material cannot gather and retain additional coating material.

Abstract: At a base of a vise a U-shaped tie element is floatingly mounted in such way that a front leg portion thereof abuts aginst the rear inner face of a stationary clamping jaw. The area of contact between the front leg portion and the clamping jaw comprises the combination of a convex nose at the one part and a planar face at the other part. The tie element is supported by resilient means which are separated from the contact area. Thereby the tie element is self-adjusting and a uniform contact is gained along the whole width of the tie element. During clamping the front leg portion is pivoted with respect to the base section of the tie element, however, thanks to a rolling line contact at the stationary clamping jaw no forces are transmitted which would angularly displace the stationary clamping jaw.
