Abstract: A lawnmower having a deck which includes a volute-shaped cutting chamber having a precisely varying cross-sectional shape and area to provide even finer mulching of vegetation clippings, such as grass clippings, prior to the clippings either being redirected back into the ground or blown out through an exhaust chute of the mower.   The volute cutting chamber includes an upper/outer corner portion having a first radius at a start point thereof.  This radius increases until the entire volute cutting chamber, when viewed in cross-section, takes on a second radius of curvature larger than the first radius of curvature when a second point approximately 90° from the start point is reached.  The second radius of curvature is maintained generally constant about the volute cutting chamber until a third point is reached approximately 135° of rotational travel past the second point.          At the third point the radius of curvature of the upper/outer corner begins to decrease until the start point of the volute is again reached.  The overall height of the volute, as well as the height of the inner lip portion of the volute, are controlled such that the height of the volute decreases from a predetermined maximum at the start point to a predetermined minimum at the first point.  The height remains generally constant until the third point of rotational travel about the volute is reached, at which time the overall height begins to increase.   Generally uniformly until the start point is again reached.  The overall height of the inner lip of the volute further "tracks" the changing overall height of the volute.

Title: Security reader for automatic detection of tampering and alteration
Inventor: MANN GRAEME R
IPC: G06K19/14
Filed: 1994-10-06
Abstract: A document (10) is covered by a laminate (13) comprising a layer of microspheres (16) over an adhesive layer (14) covering a source image (12) such as photograph, printed matter, or a bar code arranged on a substrate (11). Light impinging on the document (10) is split by the optical properties of the microspheres (16) and underlying specular reflectors. The remaining light passes through the microspheres (16), through the adhesive layer (14) and strikes the substrate (11) or source image (12) on the document (10), and is reflected (18) and scattered (20). Alternatively, the laminate (13) can comprise a plain or clear layer of polyester without microspheres over the adhesive layer (14). Light impinging on the laminate (13) passes through the polyester and laminate (14) to strike the substrate (11) or source image (12) where it is reflected and scattered. A first light source (24) directs light to the document (10). A second light source (26, 27) directs light towards a beam splitting mirror (23) which reflects the light to to the document (10). The light turning properties of the mirror (23) produce a light source which appears to an image receiver (40) as being returned from the surface of the document (10) at an angle of less than 1°. The image receiver (40) passes a signal via line (32) to a personal computer (41) which processes the received information. Such processing is to establish whether the document (10) includes a retroreflective laminate, a plain polyester laminate, or neither. Additionally, further processing can establish whether the document (10) has been tampered with, altered, or forged.
