Abstract: A roller for a device for processing a filter material ribbon in the tobacco-processing industry. The roller comprises a roller core and a covering for the roller core. The roller has at least one wear indicator operatively arranged for indicating wear of the covering.

Abstract: A diagnostic instrument for determining a cardiovascular system parameter. In one embodiment, the instrument takes the form of a portable pulse oximeter comprising a light to frequency converter (LFC) as a sensor. Also provided is a light to frequency converter comprising a photoresistor and capacitor in circuit communication with an inverting Schmitt trigger and configured such that the inverter generates a periodic electrical signal corresponding to the amount of electromagnetic radiation illuminating the photoresistor.

Abstract: A binder, with a first panel and at least one fastener. The fastener has a base attached to the panel and a binding member positionable in a closed position defining a closed loop, and in an open position in which the loop is open for mounting and dismounting sheets thereto. A lock is disposed in close proximity with the base and in releasable locking association with the binding member in the closed position. A lever is operatively connected with the lock such that depressing the lever in an unlocking direction causes the lock to release the binding member from the closed position.

Abstract: The present invention is directed to a report cover combination that includes a slide lock. The slide lock includes a wall defining a channel. Two edges define a slit extending through the wall of the slide lock along its length, and the longitudinal ends of the slide lock are sloped toward the slit to facilitate the insertion of a folded edge of a report cover into the slit of the slide lock. Preferably two parallel lips protrude inward from the edges of the slide lock at the slit. The report cover includes front and back covers having an outer surface. The front and back covers are connected by a hinge. At least one protrusion extends from at least one of the covers adjacent the hinge. The hinge of the report cover is insertable into the channel of the slide lock through the slit. The protrusion is configured and dimensioned to catch against the opposing edges of the slide lock such that the report cover resists extraction from the slide lock.

Abstract: The present invention is directed to a sheet holder comprising a spine having at least first, second, third, and fourth panels attached in series by first, second, and third hinges, respectively. The panels and hinges are configured and associated such that the spine has a folded position in which the first and second panels are opposed to each other and define a stack space therebetween dimensioned to receive a stack. In this folded position, the third panel is folded over the second panel, and the fourth panel is folded over the first panel. The panels are associated such that a binding fastener is positionable through the first panel, the stack in the stack space, and the second panel. The fastener portions of the binding fastener are disposed between the second and third panels and between the first and fourth panels such that the third and fourth panels cover the fastener portions. A spine closure fastener associated with the first and fourth covers in the folded position to cover the fastener from view.

Abstract: A set for a hunting-a-beast-prey game including two square boards each having twenty-five playing fields and four additional playing fields provided outside of the square defining the twenty-five playing fields, and two times twenty-nine playing figures consisting of twenty-five figures representing hunters, and four figures representing beasts of prey.

Abstract: A binder insert with a folder portion and a clip. The folder portion defines at least one ring aperture configured and dimensioned to receive and mount to rings of a binder. The folder portion also has a first sheet defining a clip-mounting aperture and a second sheet facing the first sheet. The clip includes first and second clip portions resiliently biased toward each other. The clip is mounted to the first sheet through the clip-mounting aperture, and the first and second clip portions are disposed in a clamping position on the exterior of the first and second sheets and compressively engaged against the sheets to bias them against each other.

Abstract: The present invention is directed to a sheet holder, a first panel defining a first window having a first window area, and a second panel defining a second window having a second window area. The first and second panels are joined by at least one hinge, such that the first and second panels are foldable about the hinge to a folded position with the first panel disposed over the second panel. In the folded position, the first and second windows are in overlap with each other such that the first window area overlaps substantially less than the entire second window area.

Abstract: The invention relates to an electric plug connection (1) with a plug holder (7) and a pin (3), especially a round-section pin (3), in which the plug holder (7) has a holding compartment in which is an axially compressible coil spring (2) having individual turns (5, 6) with the turns (5) largely having the same main diameter (dh). In order to reduce wear to the minimum even with frequent plug-in cycles and also not to increase the plugging force excessively, the invention proposes that the main diameter (dh) be larger than the outside diameter (d) of the pin (3) and that one or a few of the contact windings (6) have a smaller contact diameter than the main diameter (dh) and than the outside diameter (d) of the pin (3).
