Title: Rotary Valve Controlled Apparatus for Stripping Cans from Bodymaking Ram
Inventor: MAIN RALPH
IPC: B30B15/32
Filed: 1995-03-16
Abstract: A press for forming the relatively long cylindrical body of a so-called two piece beverage can utilizes a horizontally reciprocating ram to drive a relatively short cup through a circular die pack. Compressed air applied through a rotary valve is utilized to strip the bodies from the ram. Such valve includes a continuously rotating rotor that is mechanically connected to the drive for the ram such that for each rotor revolution the ram moves through a complete cycle consisting of a forward working stroke followed by a rearward return stroke. The rotor is constructed of two disks that abut face to face. A rotor drive shaft extends through the center of the rotor and the angular position of the disks relative to each other is adjustable to adjust the portion of each rotor revolution during which compressed air is applied for stripping. Each disk is provided with an arcuate aperture and the extent to which these apertures overlap determines how long compressed air is applied for stripping. The angular position of the rotor on the drive shaft determines when compressed air is applied for stripping.

Title: Method and apparatus for measuring retardation and birefringence
Inventor: MASON PHILIP L
IPC: G01L3/12
Filed: 1996-11-13
Abstract: This invention discloses an optical and computation system that enables the magnitude of the retardation, or the birefringence, in a birefringent material to be measured. This is achieved by consideration of the spectral interference pattern generated by combining quadrature axes of polarized light that have passed through the material, however, unlike other approaches, this invention removes the spectral intensity variations of the light source and the spectral attenuation variations of the optical system before analyzing the resultant spectral interference pattern. Since the spectral interference pattern is unique for each retardation or birefringence value, this invention provides an absolute measure of these quantities. Additionally this invention permits the full range of retardations or equivalent birefringence values to be measured, from zero retardation to any (large) value that does not create interference modulations, the frequency of which exceed the Shannon-Kotelnikov criteria for the wavelength or spectral sampling implemented. Further, in the second main embodiment of this invention, the dependence on stored light source spectral intensities and stored optical light path attenuations is removed, with the system being independent of any time dependent variations in intensity and/or attenuations and additionally, being independent of any axial alignment or setup requirements.

Patent CA-2194833-A1 (CA)
Inventor: HOPPE HUGHES H
IPC: G06T15/00
Filed: 1997-01-10
Abstract: An efficient, lossless, continuous-resolution representation (the "PM representation") of highly detailed geometric models for computer graphics specifies a succession of progressively more detailed polygonal meshes (i.e., "progressive meshes") as a base polygonal mesh and a sequence of complete mesh refinement transformations (e.g., the vertex split transformation) that approximate the model at progressively finer levels of detail.  Procedures for storing and transmitting geometric models using the PM representation address several practical problems in computer graphics: smooth geomorphing of level-of-detail approximations, progressive transmission, mesh compression, and selective refinement.  An optimized mesh simplification procedure constructs the PM representation of a model from an arbitrary polygonal mesh, while preserving the geometry of the original mesh as well as its overall appearance as defined by its discrete and scalar appearance attributes such as material identifiers, color values, normals, and texture coordinates.  In particular, the PM representation and these procedures preserve discontinuity curves such as creases and material boundaries of the geometric model.

Patent CA-2203777-A1 (CA)
Title: Slatted base for a bed
Inventor: STUEBE ANDREAS
IPC: A47C23/06
Filed: 1995-10-31
Abstract: The slatted base has two longitudinal supports, spaced apart, running essentially in the longitudinal direction of the bed, with a number of mutually spaced spring slats running transversely with respect to the longitudinal supports which collectively form a supporting surface for a matress. The spring slats are connected to the longitudinal supports via elastically formable supporting slats, the supporting slats being situated lower with respect to the spring slats. The longitudinal supports are disposed below the spring slats and the supporting slats, and are set back inwardly toward the middle with respect to the lateral edges of the slatted base. At least one spring slat and one supporting slat in each case are combined at their opposite ends with one edge-area element each into a bearing module. The supporting slat has an elastically deformable middle area situated between the longitudinal supports which is more elastic than two end areas of the supporting slat directed from the longitudinal supports toward the spring slat ends. The supporting slat is supported on the longitudinal supports and is held at the supporting places by holding-down elements. A limited pivoting of the supporting slat at each supporting place is possible in transverse direction to the corresponding longitudinal support, the pivot direction, in the case of loading of the slatted base, being opposite at the two support places at any given time. The edge-area element has a pocket-shaped holding means for each end of the spring slats and of the supporting slats. All holding means are disposed side by side in the longitudinal direction of the longitudinal supports and do not overlap in this direction. The holding means are tensionally connected among themselves with a spanning cover wall designed as bearing element. The individual spring slats are tiltably held in the edge-area element. The edge-area element itself is tiltable with respect to the supporting slat. Achieved with the proposed construction is a slatted base which ensures exceptional sleeping comfort and is aesthetically appealing.
