Abstract: A method and a waterjet machine for removing or stripping a ceramic coating from a substrate, especially from a metallic coating onto the substrate, using a pure waterjet without any additions. The method includes providing a water source and a nozzle for ejecting a jet of pure water onto the surface of a coated substrate; providing a substrate coated at least with a ceramic coating; positioning the nozzle and the substrate to one other such that a machining angle can be determined between the waterjet and the surface of the coated substrate at the location of impingement of the water jet onto the local coating surface; ejecting a pure waterjet by the nozzle impinging the ceramic coating for removing essentially or completely the ceramic coating from the substrate or from the metallic coating.

Abstract: The aim of the invention is to produce complete high temperature fuel cells by means of thermal injection processes (e.g. atmospheric plasma injection, vacuum plasma injection, high speed flame injection). The production method is especially simplified and is economical by virtue of the fact that the carrier substrate is also produced on a base with the aid of a thermal injection method. The base or an intermediate layer placed thereon can be advantageously dissolved or decomposed such that the carrier substrate provided with layers arranged thereon can be separated in a very simple manner from the base which becomes unnecessary. Said method advantageously enables the production of all layers of a high temperature fuel cell, exclusively with the aid of a thermal injection method.

Abstract: A door drive including a belt transmission incorporating a corrugated transmission belt, consisting of a strip of plastic material and adapted to be passed around a corrugated or toothed drive wheel which entrains the transmission belt, having along its longitudinal extension transversely extending corrugations of approximately sinodial or tooth shaped configuration and is made of a plastic strip permanently deformed by embossing is described. The belt has a laterally projecting side strip at least at one side of the corrugated portion, especially approximately at midlevel between the wave crests and wave troughs, to accommodate longitudinal pull. In this manner a satisfactory compromise is achieved between low manufacturing cost, little noise, and the magnitude of the driving force which can be transmitted by a corrugated belt from locking the drive gear. Likewise presented are a belt transmission and a garage door equipped with a transmission belt of the proposed type.

Abstract: An adjustable support for journals and hinge pins, especially for use with doors and gates. A rotary member (14) including an eccentrically positioned receiving bore (16) to take up a journal or hinge pin is supported so as to be rotatably adjustable in a bearing bore (12) of a bearing block (10). A setscrew (22) extending transversely of the bearing bore (12), passing through the same, is held for rotation in the bearing block (10) but fixed against axial displacement. The setscrew (22) touches the rotary member (14) such that a toothing of the type of a worm gear forms in the rotary member (14) as the setscrew (22) is turned.

Abstract: A motor driven door drive mechanism is provided having a belt transmission including a flat belt or a round belt which passes around two rotating guide wheels of which at least one is driven to take along the belt. The driven wheel is embodied by a gear and another gear is provided which loosely meshes with the drive gear, partly pressing the belt into the gaps between the teeth thereof. This arrangement offers a sound compromise between the amount of drive force that can be transmitted, and the manufacturing cost and results in low noise level in operation.

Abstract: A door drive of a up and over door, sectional side or sectional ceiling door or sliding door, especially of a garage door, comprises at least one cylindrical guide tube supported against a ceiling or side wall, has a slide carriage arranged for movement along the guide tube, an endless traction element and a drive for opening and closing the door. The carriage is connectable with the door panel via a connecting rod. The ends of the traction element are secured together by means of a turnbuckle. For better support of the guide tube and for sampler connection or coupling of the traction element with the slide carriage, a number of mounting brackets are secured to the upper side of each guide tube for receiving support struts for mounting in the guide tube to the garage ceiling or wall. The slide carriage slides with a tubular portion along the guide tube. It has a continuous longitudinal slit on its upper side so that it can pass the brackets.

Abstract: A break-in obstructing, or burglarproof door or wall, for which old motor vehicle tires are used as filling units instead of steel structures and sheeting. The treads or strips separated from the tires form mat-like, layered, and/or stacked filling units for burglarproof doors or walls and are connected with each other and to the frame by special fastening devices. This application considerably reduces the weight of such a door, and allows for burglarproof and break-in obstructing doors and walls at a much lower production cost, due to using recycling material.

Abstract: In a sound reproducing apparatus for non-rotating plate-shaped or sheet-like sound carriers a pickup comprising a tone arm and a pickup system, is supported to swivel in horizontal and vertical directions on a rotating vertical-axis tone arm table operable by a battery backed driving motor. In order to enable predetermined portions of the spiral-shaped sound groove of the sound carrier to be approached, an abutment cam is provided which is capable of being swivelled into the area of movement of the pickup and engaged therewith. Through a setting knob, adjustable from an outer surface of the housing of said sound reproducing apparatus, said abutment cam can be moved into different radial positions, with respect to the tone arm table axis.

Abstract: A sound-illustrated, bound book includes sound record areas in the form of a spiral sound groove each associated with individual pages. Adjustment perforations or embossments or engravements and switch-on safety elements, if provided, for a sound reproducing apparatus attachable in aligned position, are associated with each sound groove. It is suggested to provide the sound grooves with the adjustment perforations and the switch-on safety elements on separate double pages of plastic material, at best being semi-rigid, and bound in the book, inserted into the quaternia thereof, in order to permit more favorable production of the individual book pages and of the sound groove carriers and to prevent any obstruction when the book is read with a sound reproducing apparatus having a revolving pickup placed on the sound groove and to avoid too much bulging of the book, especially toward one side.

Abstract: A shelving for pallets in which the compartments defined by the frame are continuous in side by side relation and on top of one another and adapted to receive at least three pallets one behind the other on a support which is inclined toward a common loading and unloading side. Each compartment is provided with at least one pair of rails, which extend at an inclination toward the common loading and unloading side and accommodate two flat pallet carriages of different heights in rolling engagement, the lower of the carriages being adapted to roll completely under the higher carriage without any intervention. A further pair of rails may be disposed between the first pair of rails which receives a third very flat pallet carriage that fits completely under the lower pallet carriage. A first pallet is to be placed on the pair of rails while the second and third pallets are placed on the carriages.

Abstract: The present invention relates to a ground stabilization arrangement a structure for dam embankments and other terrain slopes and the like, consisting of interconnected elements of old automobile tires.

Abstract: An elastic street delineator or marker is formed by fixing a plurality of rubber strips to a support structure adapted to be anchored in the ground. The rubber sheets comprise tread portions of used automobile tires from which the side walls have been removed.
