Abstract: This invention refers to a mechanism for the production of rolls of coins, with a feeding track for horizontal coins. A tilting station is provided to put the coin into an upright position, and a wrapping station is provided to form rolls of coins out of the stacks of vertical coins.In order to increase the amount of coins to be gathered into stacks of coins and wrapped as rolls of coins, per time unit, and in order to reduce the size of the mechanism the invention provides a tilting station consisting of two parallel tracks which connect to a feeding track. The parallel tracks are spaced a distance from each other which is slightly less than the diameter of the coins. A coin retainer is provided with an angled surface spanning the transportation direction of the coins. The coin retainer is mounted so that it can be swivelled against the transportation direction of the coins.

It is to be possible to carry out the then necessary supply of the apparatus wearer with physiologically adapted respiratory gas mixtures varying during the ascent by simple means in order to minimize the space requirement and weight of the apparatus as well as its trouble proneness and cost of maintenance. A first compressed gas tank containing a gas mixture for great depths to the breathing bag via a fixed throttle 7, while a second compressed gas tank containing a gas mixture for small depths is so connected via a separate pressure reducer and a downstream second fixed throttle.

Abstract: A circuit arrangement for protection against fault currents in power supplies, having an energy storage means, such as frequency converters for the operation of three-phase motors. The arrangement comprises two identical detector windings in the supply lines leading to the power supply so that a differential current detector winding connected with such detector windings causes a circuit breaker device to be actuated when a given value is exceeded. This circuit breaker device interrupts all the supply lines between the power supply and a load connected therewith by means of switching paths. This ensures that despite the energy stored in the power supply there is rapid and reliable switching off of the load should a fault current occur.

Abstract: A machining control device for discharge machining equipment. The arrangement provides discharge machining equipment such that it may accomplish discharge machining on a workpiece under appropriate machining conditions suited to the progress of machining. Effective and stable discharge machining can be effected by structuring machining conditions, which are converted to control set values for the machining control device, into such a fashion as to continuously shift from a rough machining mode to a precision machining mode as an electrode travels.

Abstract: An air guiding arrangement for welding materials having plastic films includes a device to supply a uniform hot-air stream at any given air velocity.

Abstract: A pump for gas test tubes comprising two handle plates interconnected at respective ends by bellows and which are spring-biased in the direction of a suction sampling stroke. An inlet valve is constructed for the space enclosed in the bellows to insure that only non-manipulatable suction strokes with an exactly defined volume can be executed. For this purpose the inlet valve is arranged in the intake duct between the gas test tube and the interior of the bellows and closes in the direction toward the interior of the bellows. It can be opened by actuating the handle plates for the initiation of a complete sampling stroke and it remains open during the sampling stroke.

Abstract: A wall board structure is formed of one of pulverized straw, pulverized chaff and pulverized palm material having a maximum dimension of from 1 to 3 mm. The pulverized material is mixed with a substantially equal quantity of clay. A fibrous material is added to the mixture, the fibrous material including one or more of palm material fibers, hemp fibers and shredded straw, the fibrous material having a length of from 3 to 5 cm. The mixture of pulverized material and clay and the added fibrous material is poured into a form and then dried. The form preferably includes means for forming one of recesses and through holes in the poured mixture.

Abstract: A roof side sealing mechanism usable for an automotive vehicle of the type having a hood attached thereto, wherein a hood pad is provided inside of the side surface of the hood and a sealer wrap is provided in the interior of the hood, one end of the sealer wrap being secured to the inner surface of the hood at a predetermined position and the other end of the same serving as a free end which is located along a boundary or a gap between the lower end of the side surface of the hood and the upper end of a door sash.

Abstract: Machine elements formed which overcome the problems associated with rolling bearings or rolling drive units, which, apart from load under rolling are simultaneously exposed to frictional load, which leads in particular zones to frictional wear. In order to keep this to a minimum the invention teaches to apply on the effected surfaces of such structural parts a coating of a friction bearing material, which, however, according to the findings of the invention must be applied with the PVD method and must have a thickness of the order of magnitude of the surface roughness of the base body; known thicker friction bearing coatings are not suitable. The invention is especially for forming gear wheels, rolling bearings, shafts, compressor screws, and rolling pistons.

Abstract: The pane wiper apparatus for the windshield of a motor vehicle has a driven wiper implement in the form of a wiper strip which is moved over the height of the windshield. The strip is guided and driven by guide and drive elements arranged in side or edge regions of the windshield, and a prescribed tension is imparted to the wiper strip. The wiper can be guided so that it does not lift off of the pane surface even at high vehicle or operating speeds, and the wiped field is optimized.

Abstract: The invention relates to a method and a device for automatically joining and matching assemblies consisting of several components each and retained on a workpiece carrier (4) in a transfer line with retoolable machining stations (3). In the machining station (3), the assembly components are first taken off the workpiece carrier, brought into the joining position relative to each other, retained there and machined, in particular tacked or finish-welded. To carry out these various activities and to make the machining station highly flexible, the latter has several tool carriers (22, 23) which can move in at least three axes. The tool carriers (22, 23) are each disposed in a parallel plane above or below the workpiece carrier (4) so they can travel freely. The tool carriers (22, 23) support individual tools which they can change automatically at stationary or movable tool magazines (31, 33, 34).
