Granted: 2007-03-13
Abstract: A packaging material (21) has at least one line of weakness (23) consisting of weak points (25, 27) arranged at a distance in succession. For an essentially silent destruction of the line of weakness (23), there are zones of of reduced strength being preferably designed to merge continuously into one another as weak points (25, 27).

Abstract: A worm press for separating liquids from solids-liquid mixtures, the press including a worm formed as ribs on a shaft for rotation inside a worm jacket having liquid passages. The shaft of the worm includes, in the axial-conveying direction following at least one worm rib, a ribless terminal region in which the worm shaft is in the form of a jacket shaft, provided with a cavity between a shaft jacket and a shaft core. The shaft jacket includes liquid passages leading into that cavity, the cavity being in fluid communication with at least one liquid drainage means. The cavity is formed in the ribless terminal region of the worm shaft, between the shaft core, which tapers in the axial-conveyance direction, and the shaft jacket, which is fitted on the shaft and is provided with liquid passages. They thereby define a continuously increasing flow cross-section in the cavity from the liquid passages to the liquid drainage means.

Title: Trimming of fiber optic winding
Inventor: BERGH RALPH A
IPC: G02B6/02
Filed: 1993-07-21
Granted: 2002-02-12
Abstract: In an optical fiber coil arrangement for use in rota-tion sensors, for example, axial and/or radial errors can be reduced or substantially eliminated by employing trimming lengths of the first and second ends of the optical fiber used to wind the coil. The first and second ends are spatially sep-arated from one another so as to reduce such errors. The trimming lengths may be in the form of trimming turns. To eliminate axial errors, the first end is formed into a first number of trimming turns and the second end is formed in-to a second number of trimming turns so that the first and second number of trimming turns are spatially offset from each other in an axial direction. To eliminate radial errors, the first end is formed into a first number of trimming turns and the second end is formed into a second number of trim-ming turns so that the first and second number of trimming turns are spatially offset from each other in a radial direc-tion. Radial and axial compensation may be combined.

Granted: 2003-12-23
Abstract: A blister pack for containing and dispensing unit doses of medication comprises a base sheet (12) and a substantially plan-ar lidding sheet (14). The base sheet has a plurality of blister compartments (16) and a plurality of stepped edges, one stepped edge being adjacent each blister compartment. The lidding sheet (14) is peelably sealed to the base sheet (12) except at extended edge regions forming edge peel tabs (24), and the lidding sheet (14) is scored with lines of weakening (26) about each blister com-partment (16). The stepped edges underlay the unsealed extended edge regions of the lidding sheet, thus providing a finger access to thereby ease the process of grasping a given edge peel tab (24) and ultimately opening a given blister compartment (16). The invention facilitates exposure of a blister compartment (16). Further, the stepped edges of the present invention reduce undesired undulation in the base sheet (12).

Title: Out of media detection system for a roll media feed apparatus
Inventor: ZOLTNER JOHN D
IPC: B65H23/182
Filed: 1995-03-21
Granted: 1999-03-23
Abstract: An end of media detection system is provided for a system which unrolls a media supply such as paper from a cylindrical core substrate. One (trailing) edge of the media is attached to the core substrate. As part of the media detection system, a shaft which is positioned within a pair of cradles supports the cylindrical core. One of the cradles houses a plastic slide, which in turn acts vertically on the actuator of a microswitch when the shaft is in place. The weight of the shaft and media roll acting on the microswitch keeps the microswitch in an inactive state, however, as the media on the roll is played out, at some point just before the media is exhausted the shaft is moved upward due to the adhesive attachment of the trail edge of the media to the core substrate. Movement of the shaft relieves the pressure on the actuator of the microswitch thereby actuating the microswitch to send a signal to a controller to stop rotation of the shaft. This prevents a situation where the sheet still attached to the core stalls at the end of media feed.

Title: Pulverized fuel combustion burner
Inventor: OHTA HIDEAKI
IPC: F23D1/00
Filed: 1995-06-08
Granted: 1999-06-08
Abstract: In a burner for combustion of a pulverized coal mixture having two kinds of rich and lean concentration, a height of a burner panel is reduced and the overall burner is simplified. A rich/lean separator (10, 20, 30) is provided within a pulverized coal conduit (2) so that a high concentration mixture is formed in an outer peripheral portion and a low concentration mixture is formed in a central portion within a single pulverized coal conduit. Thus, a rich mixture burner and a lean  mixture  burner  which  have  been  conventionally provided separately may be formed into a single burner. A recirculation of air is accelerated by a cutaway slit (20d, 30d) provided in a central portion of the rich/lean separator to thereby make uniform the air flow rate distribution in a pulverized coal nozzle. Also, a duct and an air blow box for the combustion air to be supplied to the pulverized coal flame are not integrally formed to be continuous in the height direction but may be divided  into a plurality of discontinuous units.
