Patent number: 4537640Abstract: Articles which require the removal of an adhering substance, such as residue of a galvanizing bath, are rinsed by spraying an aqueous rinsing agent against them repeatedly. Each spraying interval is followed by a run-off interval during which the sprayed-on rinsing agent can run off the articles. The length of the run-off intervals is equal to, or greater than, the length of the spraying intervals.Type: GrantFiled: September 23, 1981Date of Patent: August 27, 1985Assignee: Schering AktiengesellschaftInventors: Rudolf Kreisel, Walter Meyer

Patent number: 4520047Abstract: The invention relates to a method and an apparatus for the recovery of spraying substance when spraying elongated rolled stock. Difficulties are met when trying to recover water-dilutable or water-soluble coating agents since after evaporation of the solvent, i.e. the water, the film which is left can no longer be dissolved by water and thus it is no longer possible to recover this fraction of the spraying substance. According to the invention, therefore, it is proposed to carry out the spraying in a water-saturated atmosphere so that the excess spraying substance can easily be recovered. The apparatus is appropriately constructed to correspond to these circumstances.Type: GrantFiled: April 21, 1982Date of Patent: May 28, 1985Assignee: Mannesmann AktiengesellschaftInventors: Herbert Hillemanns, Robert Samans, Walter Meyer

Patent number: 4459183Abstract: An electroplating apparatus and method is provided, whereby generally flat workpieces, such as metal plates and the like may be electroplated, on a continuous basis, automatically and without manual intervention. The workpieces are delivered horizontally through a bath of electrolyte. They are conveyed through the bath by being engaged by driven contact wheels that also serve as one of the electrodes. The other electrode is in the bath electrolyte solution. As the workpieces are delivered through the bath, they are engaged and disengaged by the contact wheels, but are always in engagement with contact wheels for not only continuous conveyance, but for continuous electrical connection therewith. A particular slide mount is provided for holding an opposite side of the plate as the plate is carried along its flow path, and this mount is adjustably positionable to accommodate different width workpieces.Type: GrantFiled: March 7, 1983Date of Patent: July 10, 1984Assignee: Chemcut CorporationInventors: Joseph M. Brady, Franz R. Cordes, Klaus H. Gedrat, Daniel L. Goffredo, Walter Meyer, Conrad D. Shakley

Patent number: 4244076Abstract: A method of, and apparatus for, fabricating a bristle support or carrier for a brush, especially a hair brush, having pin-like bristles is disclosed. In a first method step there are produced the rows of bristle pins interconnected with one another at their rear end by means of a web. The individual bristle pin rows are retained in their position after forming the same to accomplish the next method step. In this next or second method step the bristle pins, at the region of their rear end, together with the webs, are cast in the material of the bristle support, so that the bristle pin rows are embedded in the bristle support.Type: GrantFiled: May 23, 1979Date of Patent: January 13, 1981Assignee: Trisa Burstenfabrik AGInventor: Walter Meyer

Patent number: 4236651Abstract: A dispenser device comprising a reservoir for a flowable or fluent filled material as well as a piston pump equipped with a valve arrangement. The valve arrangement is coaxially dispositioned with regard to the pump and possesses parts connected with the piston and parts connected with the cylinder of the piston pump.Type: GrantFiled: August 17, 1979Date of Patent: December 2, 1980Assignee: Trisa Burstenfabrik A.G.Inventors: Walter Meyer, Anton J.

Patent number: 4193418Abstract: An arrangement for the prevention of excess pressure in housings of shut-off valves with varying pressure loads, in which an independent chamber is provided with two facing openings. These are connected by pressure lines to pipe sockets connected to the shut-off valves. The facing openings are closed by seals which are, in turn, connected gas-tight by elastic elements. Another pressure line discharges into the chamber space located outside the elastic elements, and this pressure line is connected to the interior of the housing of the shut-off valves. The sealing elements which close the facing openings, brace each other through a spring, and the sealing elements are connected gas-tight by a bellows. A center section is located between the sealing elements. Through drill holes in the center section and in the sealing elements, the facing openings discharge into a space enclosed by the center section, the bellows and associated sealing element.Type: GrantFiled: September 2, 1977Date of Patent: March 18, 1980Assignee: Deutsche Babcock AktiengesellschaftInventor: Walter Meyer

Patent number: 4068974Abstract: A fountain toothbrush is described which comprises a bristle carrier having bristles, a handle containing a reservoir for liquid or pasty dentifrice, a duct leading from the reservoir to the bristles, and actuating means which urge the reservoir in a direction out of the handle. A piston has a passage connected to the duct and to the interior of the reservoir and a cylinder sleeve part is provided on the reservoir into which the piston protrudes. When the piston is pushed into the sleeve part towards the reservoir, dentifrice is conveyed onto the bristles.Type: GrantFiled: July 13, 1976Date of Patent: January 17, 1978Assignee: Trisa Burstenfabrik AG TriengenInventors: Walter Meyer, Anton Bara

Patent number: 3994177Abstract: A TV tuner has a housing and a rotating channel selector shaft mounted on the housing. There are a plurality of individual support members positioned by and mounted on parallel flatted areas of the shaft, which flatted areas vary in size to assure correct placement of the support members. Individual coil strips, each carrying a tuning screw, are fixed to the shaft assembly. A simplified clutching arrangement for controlling adjustment of the screws utilizes a coil spring to provide the initial force for moving a pinion gear into operating engagement with the tuning screws. The tuning screws are held by resilient arms which bias the head of the screws toward the shaft to thus firmly maintain the screws in any adjusted position. Each of the coil strips have contacts extending outwardly from one side and positioned to be in electrical and mechanical contact with cantilever spring members fastened to a printed circuit board which in turn is held by the housing.Type: GrantFiled: March 17, 1975Date of Patent: November 30, 1976Assignee: Oak Industries Inc.Inventors: Norman D. Cappelle, Walter Meyer, Henry H. Tap
