Title: Symmetrical leading link front wheel suspension for motorcycles
Inventor: WILLIAMS GERALD J
IPC: B62K25/16
Filed: 1993-11-19
Abstract: SYMMETRICAL LEADING LINK FRONT WHEEL SUSPENSION FOR MOTORCYCLES.         Abstract of the Disclosure.         A symmetrical leading link support or attachment system for the front wheel of motorcycles, allowing near normal movement of said wheels but in which the force reactions due to the various forces applied to said wheel in the various planes of action are effective-ly divided into four major force groupings,  said force groupings being reacted mainly in individual and optimally designed members, or opti-mally spaced and located members, all of which resulting in lower stresses in members, which can now be optimally designed, This is achieved by eliminating the traditional cantilevered front fork and its attachment to a traditional frame, and by attaching the front wheel to a combination of a symmetrical lea-ding link and a symmetrical front fork at their mutual forward intersection by means of a novel central hub, which, while suppor-ting the front wheel properly, nevertheless allows near normal steering and suspension motions of the wheel. The advantages are a   potential for a lighter, less costly and better handling motorcycle.

Patent CA-2110650-A1 (CA)
Inventor: KELLER SILVANO
IPC: C23C4/134
Filed: 1993-12-03
Abstract: The plasma spray apparatus for the coating of the inner walls of bores and tubes essentially comprises a housing, a supply member, a plasma gun shaft member and a plasma gun head member. The plasma torch created in the head member escapes transversely with regard to the central longitudinal axis of the plasma spray apparatus. The supply member is rotatably received in the interior of the housing and is driven by an electric motor and a gear box. The supply member comprises a swiveling coupling member by means of which the plasma gun shaft member is connected to the shaft member. Thus, the rotatable shaft member can be radially deflected with reference to the axis of rotation. Thus, the head member fixed to the free end of the shaft member can be radially adjusted. With such a plasma spray apparatus, bores and tubes having greatly varying inner diameters can be reliably coated.
Patent CA-2114025-A1 (CA)
Inventor: PANIN VICTOR Y
IPC: G01N3/00
Filed: 1993-10-05
Abstract: A new method of nondestructive testing of mechanical behaviors of objects under loading has been invented based upon the analysis of spatial and temporal distributions of velocities of deformation and rotation under elastoplastic deformation. In order to carry out this method, optical images of the surface of an object under test are obtained as holograms of a focused image, and diffraction patterns of superimposed images are then formed for a number of consecutive time points spaced with short time intervals. These diffraction patterns are then transformed into wave patterns of space and time distributions of velocities of deformation and rotation along with the respective axes. These distributions are analyzed according to the wave theory of plasticity and strength developed by the present inventors. Wave lengths, amplitudes and velocities of relaxation waves of plastic deformation are determined, and dynamics of these parameters are used to predict the time and point of eventual failure.

IPC: A63C11/22
Filed: 1994-02-03
Abstract: The invention relates to a pole shaft for a cross-country ski pole. Longitudinal and transverse fiber layers are used for providing a hollow shaft, whose cross section changes progressively downwards into a droplet shape and, below the mid-way point of a shaft, the length of a droplet shape in relation to its width increases while the cross-sectional area diminishes.  By virtue of the droplet shape, the pole can be given more rigidity in skiing direction, whereby the bottom end of a pole can be made lighter while improving the aerodynamics of a pole.
