Title: Apparatus and method for distributing product on a conveyer
Inventor: HURD RONALD D
IPC: B65G69/04
Filed: 1992-09-24
Abstract: TITLE          Apparatus and Method for Distributing Product on a Conveyer ABSTRACT OF THE DISCLOSURE     An apparatus (10) for evenly distributing coated cereal pieces across the width of a conveyer is disclosed including a steep angled, V-shaped plow (24) supported in varying angular positions by saddles (38) above the conveyer.  Specifically, three saddles (38) slideably support a semicircular shaped carrier (12) secured to and between the first and second legs (26, 28) of the plow (24). A connector arm (66) is connected to a leg (28) of the plow (24) for moving the carrier (12) and the plow (24) secured thereto along an arc having a center downstream of the interconnection of the legs (26, 28) of the plow (24) and in the preferred form at the center of the semicircular shape of the carrier (12) . The saddles (38) are vertically, adjustably secured to a support arm (46) which in turn can be raised or lowered relative to the conveyer.  The plow (24) is positioned to engage the product pile on the conveyer and due to the steep angle of the legs ( 26, 28) of the plow (24) and the Teflon? nature thereof, the coated cereal pieces spread quickly and evenly across the width of the conveyer.  The angular position of the plow (24) is varied to conform to the variations in the product pile on the conveyer.

Inventor: LUKAS HELMUT H
IPC: G02B6/24
Filed: 1991-05-30
Abstract: An optical fiber mechanical splice comprises a pair of gripping members (110, 140) and a resilient biasing member (150). Each gripping member has a plastically deformable gripping surface (124 142). One of the gripping surfaces has a v-groove (144) for receiving and aligning optical fiber ends. The resilient biasing means acts between the gripping members to resiliently bias the gripping surfaces of the gripping members toward one another. In use of the mechanical splice, the gripping surfaces are urged toward one another with optical fiber ends in abutting alignment in the v-groove. The gripping surfaces plastically deform around the fiber ends to provide a larger area of contact between the fiber ends and the gripping surfaces.

Title: Improvements in microporous filter assemblies
Inventor: SELBIE MICHAEL R L
IPC: B01D63/04
Filed: 1991-04-19
Abstract: An improved microporous, modular filter structure assembled from replaceable filter cartridges (25) housed within a filter cartridge assemby (10) connected at opposed ends by means of symmetrical headers (41). The headers include a tube within a tube structure where-by they are adapted to conduct first and second fluids independently to both adjacent, like interconnected headers and into and out of filter cartridges (25) to which each header (41) is connected at both ends of each cartridge. Manifolds (100, 101) include a similar tube within a tube structure which allows them to be connected to the ends of rows of interconnected headers (41) whereby a modular filter bank can be constructed of indefinite dimension and capacity. A valve assembly (63) can be installed in each header (41) whereby the passage of one of the two fluids conductable from the filter cartridge assembly (10) to the header (41) can be isolated from the header ducts so that contamination of the output from adjacent headers can be selectively prevented.

Filed: 1992-01-31
Abstract: A vibration assembly comprising a housing (12) having a central cavity (20) and a pair of side cavities (22, 24) of radially smaller dimension than that of the central cavity, all of which extends axially about an axis (26) from opposed ends of the central cavity.  A piston (50) is housed within the cavities (20, 22, 24) and includes a mass (52) disposed within the central cavity (20) and a pair of supports (54, 56) which are disposed within respective ones of the cavity pair (24, 22) and which extend axially from the mass.  The supports (54, 56) have radial dimensions which are substantially the same as those of the pair of cavities (22, 24).  The mass (52) and the supports have axial dimensions which are substantially less than those respectively of the central cavity means and of the pair of cavities (20, 22, 24) for enabling the piston (50) to move axially within the cavities.  Air inlets (61, 62) in the housing and conduits (66, 68) in the piston enable the piston to reciprocate within the housing for repeated impact against an impactor (38) for transmission of energy thus obtained to a test table and an item under test.

Title: Method and apparatus for performing corneal reshaping to correct ocular refractive errors
Inventor: BERRY MICHAEL J
IPC: A61F9/01
Filed: 1991-07-23
Abstract: A noninvasive method is described for performing accurate and controlled reshaping of the anterior surface of the cornea in order to correct ocular refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The invention uses a light source emitting a wavelength or wavelengths with correct optical penetration depth(s) to induce changes in corneal stromal collagen without damaging the corneal endothelium, together with a light delivery and control means for producing the required irradiance, exposure time, and geometric pattern, in order to achieve the desired change in corneal shape. Corneal shape is monitored before, during, and after the procedure by a corneal topography system. Anterior corneal surface cooling by a transparent heat sink is used to prevent damage to the epithelium and to Bowman's layer.

To produce a multicolored image, these steps are repeated with  at  least one  further single-color  sheet.   The material has increased photosensitivity and gives color prints with lower background discoloration.

Title: Means and method for enhancing plant growth under field conditions
Inventor: ERICKSON STEWART E
IPC: B61D7/02
Filed: 1991-10-22
Abstract: An economic and practical system for enhancing plant growth by delivering gaseous carbon dioxide (30) to the plants. The vegetation is planted within an elongated trench (10) preferably in an overstocked condition whereby the vegetation is permitted to grow sufficiently to define a closed canopy. The carbon dioxide-rich gas (30) may be delivered to the trench by conduits (32) beneath the level of the canopy. The trenches can include a floor (12) and sidewalls (14) which extend vertically upwardly and divergently from each other to restrict the flow of air beneath the canopy thereby minimizing the dilutive effects of the atmosphere. The trenches (10) can also be oriented generally perpendicularly to the prevailing wind direction to minimize the tendency of the wind to carry off the carbon dioxide (30).

Filed: 1991-11-28
Abstract: The invention relates to a traction device intended to be fastened on an extremity of a person with joint trouble and comprises a base material (1) on which a number of pockets (2) meant to carry weights are arranged. According to the invention the device is so designed that the base material (1) reaches essentially around the whole of the extremity, so that the device by its own force can be kept in place on the extremity without tendency to slip down. The pockets (2) are placed at regular distances from each other around essentially the whole of the device. Further, the pockets (2) are oblong and have a direction that is principally perpendicular to the longitudinal direction of the device. The traction is brought about by the putting of one or more thin weights into each pocket (2), whereby the weights have a shape which corresponds to those of the pockets (2).
