Abstract: An oil scraper piston ring includes an inner circumferential surface; an outer circumferential surface adapted to contact and slide along an inner wall of an engine cylinder; a radial wall thickness defined by a radial distance between the inner and outer circumferential surfaces; and a plurality of circumferentially distributed recesses each extending radially from the inner circumferential surface toward the outer circumferential surface to reduce the radial wall thickness. Each recess has a first recess region open at the inner circumferential surface and extending radially toward the outer circumferential surface and a second recess region merging into the first recess region. The two recess regions have different shapes, and the area of the second recess region is larger than the area of the first recess region.

Abstract: The distributor of a cigarette rod making machine employs a zig-zag sifter which receives a mixture of tobacco ribs and shreds from a reservoir by way of a duct or an elevator conveyor. The shreds leave the uppermost stage of the sifter and are conveyed, by a Coanda separator, into an upright gathering duct which discharges shreds for delivery onto the concave surface(s) of one or more guides serving to direct one or more streams of shreds against the underside(s) of one or more foraminous belt conveyors which advance the stream(s) past one or more trimming devices serving to remove the surplus and to thus convert each stream into a rod-like filler which is ready to be draped into a web of cigarette paper. The removed surplus is returned into the reservoir or directly into the zig-zag sifter.

Abstract: A band saw machine includes a saw band for severing a workpiece in a cutting plane; a saw band support for swinging the saw band into the cutting plane before each sawing step; clamping jaws disposed downstream of the cutting plane as viewed in the feed direction for clamping the workpiece undergoing sawing; and feed jaws for advancing the workpiece toward the cutting plane. The feed jaws are openable after closing the clamping jaws and before ending a sawing step, shiftable from the cutting plane to an extent of a successive work piece feed and closable for moving the workpiece against the feed direction away from the cutting plane after the sawing step. An arrangement shifts the saw band support away from and perpendicularly to the cutting plane toward the workpiece held spaced from and upstream of the cutting plane prior to retracting the saw band from the cutting plane.

The optical attenuator is also provided with an opening in the holding sleeve so as to communicate with the outside. A filler is supplied into the sleeve through the opening.

Abstract: Cutter plates (19) with an approximately cube-shaped base body have been created, in particular for finish-milling of a crankshaft (5). At the edge of its cover surface, the base body is provided with a hump or protrusion, which can be embodied rib- or strip-shaped, has a cutting edge each on its front and back and adjoins the neighboring lateral surface. This cutting edge is a component of the main cutting edge (33) adjoining the cover surface. A corresponding protrusion (29) is provided on the lower end of the lateral surface (27) and adjoins the end of the cover surface (22) remote from the protrusion (28). In this case the lateral surface (27) is preferably inclined in such a way that it terminates flush with the protrusion (29) without forming a concave surface area with it.

Abstract: An apparatus for confining commodities in containers each of which consists of several components. The commodities are advanced along an elongated path past a series of stations where the components of the containers are draped around successive commodities. At least some of the components are provided with characteristic indicia, and a control circuit processes the indicia into information which is encoded upon the finished containers. Such information is decoded, when necessary, to ascertain the genuineness or lack of genuineness of the commodities, for example, the identity of the maker and packer of cigarettes in cigarette packs.

Abstract: A vehicle seat includes a squab and a back mounted for pivotal movement relative to the squab. A support plate is mounted to the squab, and the back of the seat is pivotally mounted to the support plate. A mechanism for providing a resistive force resists a first pivotal movement. The providing mechanism provides a first resistive force during a first energy impact and a second resistive force during a second energy impact. The first energy impact is a higher energy impact than the second energy impact.

Abstract: This invention relates to methods and apparatus for producing a discretely striped, multi-property foam and the products and articles produced thereby. The invention provides a pre-foam stream at a first pressure and intermittently injects at least one additive into the pre-foam stream at a pressure higher than the first pressure, providing a laminar flow pre-foam stream with alternating segments having different properties. The pre-foam stream is poured onto a surface and cures into a discretely striped foam product which may be used for many purposes such as but not limited to padding, clothing, toys, or bedding.

Abstract: A method of detecting impurities in a mass, such as detecting metallic and/or plastic particles in a stream of tobacco particles or filter material for tobacco smoke, includes the steps of moving the mass relative to a microwave field and/or vice versa, and analyzing the influence of the mass upon the microwave field. The analyzing step involves simultaneously measur- the actual values of a first and a second parameter of the microwave field, ascertaining the presence or absence of those changes of the parameters which are attributable to the presence of impurities in the mass, determining whether or not the changes are within an acceptable range, and generating signals for segregation of impurities-containing portions of the mass from the other portions when the changes are outside of the acceptable range.
