Patent number: 5695535Abstract: A pocket filter includes a front frame which accommodates at least two filter bags. The top of each bag accommodates a reinforcing frame. The bags are secured dust-tight to one another, to the reinforcing frames, and to the front frame. The front frame is a severed at at least one point along its perimeter. The front frame has a U-shaped channel around it that opens inward, and the reinforcing frames can be inserted into the channel when the front frame is open at the severed point. The reinforcing frames match each other and match the size of the front frame, creating a dust-tight contact between all the adjacent reinforcing frames and the inner surface of the channel when the front frame is closed at the severed point. Facing webs, disposed in the channel opening on each side of the "U", create a dust-tight contact with the reinforcing frame.Type: GrantFiled: March 27, 1997Date of Patent: December 9, 1997Assignee: Carl FreudenbergInventors: Dieter Hintenlang, Dieter Unrath, Udo Michaelis, Margit Hofmann

Patent number: 5694150Abstract: A graphical user interface system is provided having an event-driven control program with a unified user input pointing event stream without distinction of source and a graphical user interface having a virtual display space containing objects. The control program processing events related to a plurality of user inputs representing different locations within the virtual display space, and operates optionally in two modes. A first mode permits the plurality of user inputs to interact, allowing an object in the virtual display space at a first location specified by an initial user input to be associated with a second location specified by a concurrent and subsequently terminating user input. In this case, the control program has a counter which increments on activity of any user input and decrements on cessation of activity of any user input, for determining an initial user input condition, temporal concurrence of a plurality of user inputs, and a terminal user input condition.Type: GrantFiled: September 21, 1995Date of Patent: December 2, 1997Assignee: Elo Touchsystems, Inc.Inventors: Michael R.

Patent number: 5668625Abstract: An apparatus and method for handling photographic film within the print-exposure section of a photographic printer. A mask matches the film frame (negative) and has a window for the passage of the exposure light. The mask also has holes through which air can be directed onto the film. A guide for the edges of the film parallels, and demarcates a gap with the mask. A source of air under either overpressure or underpressure supplies such air to the mask (4) and the film (1) through the air-direction openings (15). The air is supplied with overpressure while the film is being advanced. The air is supplied with underpressure while the print is being exposed to clamp the film.Type: GrantFiled: July 28, 1995Date of Patent: September 16, 1997Assignee: Agfa-Gevaert AktiengesellschaftInventors: Siegfried Bocklisch, Wolfgang Fielder, Helmut Treiber, Rainer Leuschner, Wilfried Reichel, Michael Wilde

Patent number: 5645897Abstract: The invention concerns a process and a device for surface-modification by physico-chemical reactions with the following steps: a) contacting a solid surface having a crystalline or amorphous structure with a reactive, gaseous fluid (gas, gas mixture, vapour or vapour mixture) which is to interact with the surface; (b) supplying activating energy to the contact area between fluid and surface by means of ions or plasmas, in order to trigger reactions between said partners. In order to improve such a process and device, the activating energy is supplied as ions having at least a double charge and low kinetic energy or plasma streams with a sufficient proportion of ions having at least a double charge and low kinetic energy. The kinetic energy imparted to the ions is selected so that it allows the ions to closely approach the surface atoms but no to enter the surface.Type: GrantFiled: January 18, 1995Date of Patent: July 8, 1997Inventor: Jurgen Andra

Patent number: 5633495Abstract: The invention pertains to a process for operating a time-of-flight secondary ion mass spectrometer for analysis of mass spectra, wherein a number of finely structured mass ranges appear in isolation at major intervals, involving the following steps: a) a surface of a material sample is bombarded with primary ion pulses that follow each other at regular time intervals t.sub.z (cycle time), b) the secondary ions of various masses m released from the material sample surface by the primary ions are accelerated to the same energy, c) the mass-dependent time of flight t is measured over a path 1 and the mass is determined therefrom. To increase the resolution and the signal-to-noise ratio the process is characterized in that: d) each primary ion pulse consists of a number of subpulses, e) each subpulse is so narrow that it allows for resolution of the finely structured mass ranges, g) the number n of subpulses is selected so that n.multidot.t.sub.Type: GrantFiled: February 9, 1996Date of Patent: May 27, 1997Assignee: ION-TOF GmbHInventor: Ewald Niehuis

Patent number: 5621173Abstract: A method and apparatus for non-contact determination of the weight per unit area and the thickness of thin materials. This involves directing an ultrasonic wave at the material and measuring the proportion of sound energy that passes through the material. The process is distinguished by the fact that the time intervals between the ultrasonic pulses are greater than the propagation time. At the receiver only the signals that exceed a certain amount and are shorter in duration than the propagation time are evaluated.Type: GrantFiled: April 26, 1995Date of Patent: April 15, 1997Inventor: Helmut Knorr

Patent number: 5607285Abstract: A pump drive apparatus comprises a housing (1) that accommodates a shaft (2) and a pump impeller (3). Both rotate around the same axis (4). The impeller rotates against the housing on at least one bearing (5). There is an eccentric journal (6) on the end of the shaft inside the impeller. The journal rotates in an orbital journal bearing (7). The orbital journal bearing moves in a circle within an eccentric bearing 14 on the impeller, driving the impeller. The orbital bearing tightly encloses the journal. A flexible component (9) prevents the orbital bearing from rotating in, and seals it off from, the housing.Type: GrantFiled: May 26, 1995Date of Patent: March 4, 1997Assignee: Carl FreudenbergInventor: Hans-Gerd Eckel
