Title: Combined rotary web-fed printing machine, especially for the printing of securities
Inventor: LAPP JOACHIM ALFRED HEINZ
IPC: B41F11/00
Filed: 1990-08-02
Granted: 2000-02-29
Abstract: The rotary web-fed printing machine has three successively-arranged printing units, namely one offset and two intaglio printing units which are all of a similar design to sheet-fed printing units and in which the cylinders forming the printing nip have a plurality of sectors separated by cylinder pits. Each printing unit has, in front of the printing nip, a first paper-web store and an intermittently controllable first draw-roller unit and, after the printing nip, an intermittently controllable second draw-roller unit and a second paper-web store, the draw-roller units which have only one suction roller being controllable for the forward and backward movement of the web by means of individually regulated drives and at the same time serving for the register check. In front of the first paper-web store of the first printing unit, between the printing units within the portions limited by the respective paper-web stores and behind the second paper-web store of the last printing unit, the web is moved uniformly by continuously driven draw-roller arrangements, whereas during the run through the printing nip the paper-web transport takes place in the pilgrim-step mode.

Title: Method for measuring the cyclic speed of a traveling looped belt
Inventor: DOUGALL RYAN P
IPC: G01P3/50
Filed: 1990-09-05
Granted: 1994-07-19
Abstract: ABSTRACT OF THE DISCLOSURE     A system for determining the rotational, or cyclic, speed and rotational position of a looped traveling belt, such as a felt in a papermaking machine, utilizes a discontinuity, or caliper variation, in the surface of the belt near one edge thereof.  A fluid stream, such as compressed air, is projected against the web along the annular area containing the discontinuity, and a pressure transducer is mounted in fixed proximity with the belt downstream of, and aligned with, the fluid stream.  The transducer senses differences in the pressure of the fluid stream projected against the belt and against the discontinuity, and produces a signal indicative of the passage of the discontinuity past the transducer.  The time interval of this signal is used to compute the cyclic speed of the traveling belt and to identify the part of the belt passing through a nipped roll couple at another location.

Inventor: ANDERSSON ROLAND
IPC: B65B51/00
Filed: 1990-11-02
Granted: 1995-03-28
Abstract: Heating apparatuses for packaging materials operating with hot air are often employed for heating thermoplastic packaging materials in connection with heat-sealing, forming or the like. The heating apparatuses are energy-intensive and suffer from a relatively low degree of efficiency, which primarily relates to a considerable waste flow of heated air. A heating apparatus in which these draw-backs have been obviated displays a suction box provided with aper-tures, the box being located adjacent a nozzle for the hot air and connected, by the intermediary of a recirculation duct, to the in-take side of means generating an air current.

Title: Method of increasing the rate of production of methane from a coal seam
Inventor: PURI RAJEN
IPC: E21B43/00
Filed: 1991-03-14
Granted: 1994-04-26
Abstract: ABSTRACT OF THE DISCLOSURE            A method of increasing the rate of methane pro-duction from a coal seam includes introducing a desired volume of a gas, that causes coal to swell, into the coal seam adjacent a wellbore, maintaining the coal seam adja-cent the wellbore in a pressurized condition for a period of time to permit the gas to contact a desired area of the coal adjacent the wellbore, and relieving the pressure within the coal seam by permitting fluids to flow out from the wellbore at a rate essentially equivalent to the maxi-mum rate permitted by the wellbore and any surface well-bore flow control equipment.  Uneven stress fractures should be created in the coal by this method which will increase the near wellbore permeability of the coal seam.

Title: Microcellular communications system using space diversity reception
Inventor: GORDON ALEXANDER
IPC: H04W92/04
Filed: 1991-10-16
Granted: 1994-07-19
Abstract: MICROCELLULAR COMMUNICATIONS SYSTEM USING SPACE DIVERSITY RECEPTION Abstract Microcellular stations are transceiving units covering a relatively small geographic area and adapted to establish bidirectional links between mobile telephone subscriber stations and a main base station. Each such microcellular station includes a transmitter for generating outgoing signals directed to the main base station over an optical fiber link. Radio signals received from a mobile station at a separate diversity antenna of the microcellular station are frequency shifted and combined with other signals received from the mobile station. The transmitter at the microcellular station generates an optical carrier signal which is modulated by the resulting combined signals. A frequency converter, located at the main base station, restores the frequency band of signals received from the microcellular station to its original frequency. Frequency shifting and conversion are implemented at the microcellular station and at the main base station by frequency mixing steps performed by oscillators at both locations, which oscillators use the same reference frequency thereby achieving channel coherency.
