Patent number: 6296359Abstract: In a cinematic film projector a light source projects light through a single, non-centric light transparent transmission window formed in a rotary shutter, and through an image window and an image of a film which passes step by step past the image window for projection by a projector lens onto a cinema screen. In order to obtain a higher image frequency, the rotary shutter is made of light transparent material that is coated so that light passes through only its single light transmission window. Thereby the rotary speed of the rotary shutter can be significantly increased.Type: GrantFiled: September 17, 1999Date of Patent: October 2, 2001Assignee: Ernemann CineTec GmbHInventor: Hans Baumann

Patent number: 6230756Abstract: A heddle system for mechanical looms consisting of heddles (51) as well as upper and lower heddle slide bars (52, 53) that are attached to a heddle frame whereby said heddles are lined up on said heddle slide bars. Said heddles are provided with two end eyes (56, 57) whereby the ones (56) that are disposed within the heddle frame and above the warp threads have less play in longitudinal direction of the heddles, while said heddle eyes encompass the upper heddle slide bar (52), in comparison to the particular end eyes (57) that are disposed below the warp threads. The upper and lower heddle slide bar has each a different cross-sectional dimension or a difference width according to one embodiment version.Type: GrantFiled: July 11, 2000Date of Patent: May 15, 2001Assignee: Grob Horgen AGInventors: Hans Baumann, Franz Mettler

Patent number: 6014198Abstract: The invention refers to a method of shortening the closure time of shutters in cinema projectors of the type in which film is intermittently advanced one frame at a time into registry with an image window in the projector, and wherein each time the film is advanced a shutter in the projector closes the image window during the time that the film is being advanced. According to the invention, an optical compensation of the film motion is effected by determining the rate at which each image of the film begins and ends, respectively, its advance into registry with the image window of the projector, generating a control signal proportionate to the rate, and positioning between the image window and the associated projection screen a movable plane-parallel plate which is adjsuted by the control signal to shorten the closure time of the image window during each film advance, thereby to increase the luminous efficiency factor of the projector.Type: GrantFiled: May 27, 1997Date of Patent: January 11, 2000Assignee: Raytheon Anschutz G.m.b.H.Inventor: Hans Baumann

Patent number: 5908414Abstract: An improved implantable infusion pump comprises a propellant chamber, a medicament chamber, and a throttle section. Enclosed within the throttle section is a medicament delivery system comprising a chip having a fluid path etched in an upper surface, inlet and outlet depressions formed in the chip lower and upper surfaces respectively, and a channel formed through the chip connecting the inlet with the fluid path. A planar cover, preferably transparent, covers the chip upper surface. A pair of wafers surround the chip within the throttle section and pair of silicon coatings are positioned between the chip and the pair of wafers. Various bores, apertures, and recesses are formed in the wafers, the cover, and the coatings, for permitting the medicament fluid to pass through the throttle section.
