Patent number: 4193184Abstract: A stator having a plurality of permanent magnets with a cylindrically shaped outer surface and with at least one planar opposite surface is manufactured to close tolerances of the air gap with the aid of a plurality of ferromagnetic link members, equal in number to the number of permanent magnets and adapted to come into planar contact with those surfaces of said permanent magnets which are pointing away from the air gap. The permanent magnets are placed into a cylindrically shaped sleeve, the inner diameter of which corresponds to the desired inner diameter of the air gap of the stator. A sleeve of a ferromagnetic material may be used for holding said permanent magnets in intimate contact with the sleeve. The link members are shaped so as to be brought into generally planar contact with at least part of the inner surface of two adjacent ones of the permanent magnets. An adhesive is used to secure the link members to the permanent magnets.Type: GrantFiled: September 15, 1978Date of Patent: March 18, 1980Assignee: Interelectric AGInventor: Bodo Futterer

Patent number: 4173822Abstract: A method for assembling a stator for an electric machine having a permanent magnet for generating a magnetic field in an air gap. Assembly of the stator is performed with the aid of a plunger, the cross-section of which corresponds to the cross-section of the air gap. The permanent magnet is slid into the interior of the plunger, whereas the flux return ring is slid over the same. The so formed sub-assembly is put into a casting mold adapted to be filled with a plastics material, which in its cured or hardened state forms a casing intimately surrounding the outer surface of the flux return ring and forming a face plate, to which the permanent magnet adheres. When the plastics material has set, the casting mold is opened and the plunger is retracted from the sub-assembly, resulting in a close toleranced cylindrical air gap space. After insertion of a bell-shaped rotor, a brush cover is assembled opposite the face plate.Type: GrantFiled: December 30, 1977Date of Patent: November 13, 1979Assignee: Interelectric AktiengesellschaftInventors: Bodo Futterer, Jurgen Mayer, Hugo Fritschy

Patent number: 4157868Abstract: A photographic developing tray is described having such configuration as to provide, when placed at an angular position, a trough adapted to contain a certain amount of processing solution. The inner wall of the trough, so formed, has a predetermined slope whereby, upon gradually moving the tray into a horizontal position, the solution contained in the trough cascades over the sloping surface onto a photographic sheet material placed on the bottom of the tray at a substantially uniform flow pattern.Type: GrantFiled: June 20, 1977Date of Patent: June 12, 1979Inventor: Samuel Needleman
-
Patent number: 4143569Abstract: A die holder for punch presses for placement in a die set is described. It consists of a die element retained by a frame member supported on pads secured to a die block. A sliding support between the die element and the die block is provided, reinforcing the die upon impact of the punch. The frame member is undercut, permitting saving of material and distribution of mass at points of maximum stress.Type: GrantFiled: July 20, 1977Date of Patent: March 13, 1979Inventor: Joseph Marconi

Patent number: 4125791Abstract: A stator for an electrical machine, comprising an outer ferromagnetic flux return ring, a permanent magnet system arranged inside the flux return ring, and a face plate supporting the flux return ring and the permanent magnet system. The latter comprises at least four permanent magnets, each of which is shaped cylindrically at its outer surface, and an equal number of magnetically conductive link means, each of which abutts the inner surface of two adjacent permanent magnets. The link means serve to support the permanent magnets and may be bonded to the same. The stator is easy to manufacture with a low toleranced air gap and is of a rigid construction.Type: GrantFiled: November 5, 1976Date of Patent: November 14, 1978Assignee: Interelectric AGInventor: Bodo Futterer

Patent number: 4093364Abstract: A photographic recording arrangement to be mounted in a motor vehicle, particularly for use by law enforcement personnel, is described. The arrangement includes a camera of specific construction which is mounted on the dashboard and is capable of automatically taking, on a reel of film, sequential frames of pictures of the vehicle under observation, thus recording the license plate thereof, as well as the behavior of the driver handling the vehicle and, in another sequence, photographically recording, in a given number of frames, the speedometer reading of the car in which the camera is mounted.Type: GrantFiled: February 4, 1977Date of Patent: June 6, 1978Inventor: Keith G. Miller
-
Patent number: 4085639Abstract: A blanking die comprises a relatively thin die plate having a cutout into which the punch of the press, upon blanking operation, forces the material to be cut to form the required part blank. A holder of sturdy construction is provided onto which the thin die plate is removably mounted. Slidably positioned within the holder is a reciprocating support block which, upon blanking operation, underlies the thin die plate in order to reinforce it against the impact of the punch. After the blanking cycle, the support block is moved either to eject the part blank or to allow the latter to fall through an opening in the holder.Type: GrantFiled: February 23, 1976Date of Patent: April 25, 1978Inventor: Joseph Marconi

Patent number: 4075590Abstract: A bobbin construction, particularly for windings surrounding an assembly of ferromagnetic laminations, is described. It consists of a skeletal frame member of molded plastic having an elongated shape, generally of rectangular cross section, over which a winding may be wound. The frame member has laterally extending walls which define the space for the windings and axially extending walls defining the space of the laminations. The latter walls are so constructed as to support covers for enclosure of the core assembly.Type: GrantFiled: February 22, 1977Date of Patent: February 21, 1978Inventor: Stephen Foldes

Patent number: 4070955Abstract: A filtering device for the preparation of coffee, with a pot-shaped vessel, at the bottom of which a sieve sheet is attached, and with a water distribution plate, which is adapted to be supported by the upper edge of the vessel. The diameter of the water distribution plate is smaller than the inner diameter of the vessel, and a plurality of feet protrude from the edge of the water distribution plate nearly perpendicularly to the surface of the same. The free ends of the feet each form a shoulder, which serve to rest on the upper edge of the vessel such that the water distribution plate lies within the interior of the vessel and leaves a circumferential clearance to the same. Hot water which is poured onto the water distribution plate flows through that clearance onto the coffee powder. The water distribution plate may be removed from the vessel and laid onto a surface with its feet down as a base plate for the vessel, thus collecting water that might still pass through the filter.Type: GrantFiled: November 22, 1976Date of Patent: January 31, 1978Assignee: Maxs AGInventor: Werner Braun
-
Patent number: 4062139Abstract: Erectable sign structure consisting of two boards interconnected so as to be placed in a V-formation and magnetically secured to a metallic body, such as a motor car. The outer surface of the structure is adapted to hold information sheets for display, indicating various emergency situations facing the motorist. The information sheets are permanently secured to the structure in a fold-over manner so as to be selectively chosen by the user.Type: GrantFiled: December 1, 1976Date of Patent: December 13, 1977Inventor: Georg W. Klosel
-
Patent number: 4050468Abstract: A pocket ash receptacle of U-shaped configuration comprises a flat pouch of flexible material adapted to be opened by compressing the edges thereof. A reinforcing resilient metallic wire frame insert, shaped to follow the edge configuration, is located within the pouch. Upon opening of the pouch by exerting lateral pressure, a portion of the insert forms a solid body across the mouth of the pouch over which the end of a cigarette may be passed for removal of the ash or against which the burning end may be snuffed out. In one modification, the solid body of the insert across the mouth of the pouch has such configuration as to permit the cleaning of the bowl of a pipe.Type: GrantFiled: October 28, 1976Date of Patent: September 27, 1977Inventor: Eugene E.
