Title: Filter cigarette
Inventor: HOUCK WILLIE GRAY
IPC: A24D3/04
Filed: 1983-09-23
Granted: 1986-12-11
Abstract: A filter cigarrette is provided which is adjustable to provide a wide range of air dilution and/or resistance to draw values and which comprises a tobacco rod 1, a substantially cylindrical filter plug and substantially air impermeable tipping paper 11. The filter plug comprises a first, mouth-end segment 7 and a second, axially aligned, rod-end segment 3 spaced apart from the first segment. The wrapping, which is substantially air impereable, circumscribes the first and second segments defining a substantially cylindrical void 8 therebetween which may include means for releasing varying amounts of a flavourant. The first segment is movable towards the second segment thereby compressing the plug wrap between the segments which decreases the volume of the void and increases the resistance to draw value of the cigarette. Variable air dilution may be achieved by providing at least one opening 17 in the tipping paper and at least one opening 19 in the underlying plug wrap positioned such that, as the first segment is moved axially towards the second segment, the first and second openings are moved into varying degrees of registry thereby emitting varying amounts of air to the filter.

Title: Enzymatic atp and fmn assay
Inventor: FOSSATI PIERO
IPC: C12Q1/48
Filed: 1984-12-10
Granted: 1989-10-05
Abstract: An enzymatic determination of one of the coenzymes adenosine triphophate (ATP) or flavin mononucleotide (FMN) based on the use of an flavine adenine dinucleotide (FAD) synthetase-active system in conjunction with the other coenzyme to generate FAD. The generated FAD can then be measured to determine the ATP or FMN concentration in the sample. Preferably, the generated FAD is measured by combination with a corresponding apoenzyme, preferably apo(glucose oxidase), and measuring the activity of the enzyme produced. The resultant active enzyme is preferably measured in a manner which results in a colorimetric response. The present invention provides an ATP or FMN assay which combines the sensitivity of bioluminescent assays with the convenience of a colorimetrically detectable response.

Granted: 1989-10-19
Abstract: The apparatus travels along a multi-tier arrangement of poultry cages, each tier comprising two rows of cages, the cages in these two rows adjoining back-to-back. The apparatus has transversely spaced, depending side units travelling along the cage-fronts and each including a feed container and a lift conveyor lifting feed from the container up to levels associated with the different tiers. At each such level a respective outflow chute on each side unit receives feed, continuously, from the lift conveyor and discharges the same into a feed trough that extends horizontally along the cage-fronts at the respective long side of the multi-tier cage arrangement, so that during dispensing-apparatus travel each longitudinally successive portion of the feed trough receives feed directly from the travelling outflow chute's discharge end. Each chute has an internal feed-flow passage formed by an inclined bottom wall, down along which the feed slides, as well as side walls and a top wall. A large part of the bottom wall is absent, forming a wall opening through which the face of a rotating disk is exposed, this face forming part or most of the passage's bottom boundary surface. During dispensing-apparatus travel, each disk rotates to prevent feed in the chute from cohering therein in a manner that could result in undesirable brief clogging of such feed with resultant undesirable non-uniformities, or even gaps, in the longitudinally extending carpet of feed that the travelling outflow chute is laying down along the length of the feed trough.
