Abstract: A solid modeler is provided which is specifically tailored for the material removal process associated with milling procedure. The solid modeler permits a part to be designed using only machinable profiles thereby constraining the designer to real world machinable operations. The method utilized by this solid modeler allows design manipulation of the edges and curves of a very general feature profile, thereby representing the milling process with the same degree of flexibility that the actual milling process has, and provides a means to create and store for use in the generation of other parts any combination of 2D and 3D features.

Abstract: A protrusion, which has three stepped recesses inside, is formed on an outer surface of a spool cover at the center which is a confronting member of a spool. A thrust bearing is fixedly set in the bottom of the recess, and a bearing is fitted in the recess. A guide member is fitted in the recess. The guide member and the bearing are prevented from coming off by a spring washer. The guide member has an inserting hole into which a spool shaft is inserted which is slightly larger in diameter than the inside diameter of the bearing. The guide member has a tapered guide surface around the inserting hole to guide the spool shaft to the inserting hole. The guide surface and the inserting hole enables smooth insertion of the spool shaft into the bearing.

Abstract: The invention concerns a biodegradable article which can be used for a period of time of normal use while the performance and quality are maintained high and further the biodegradable article exhibits an excellent biodegradability in the natural environment. The biodegradable article includes: a member body made of biodegradable material having a predetermined profile; and a coat formed on a surface of the member body, wherein the coat delays the biodegradation of the member body for a predetermined period of time.

Abstract: An electronic circuit connected in series with one or more brake condition sensors having a first transistor and a second transistor connected to intermittently power an indicator lamp upon initial power-up to confirm circuit operational status and subsequently to activate the indicator lamp if the brake condition sensors are acceptable and to deactivate the indicator lamp if any one of the brake condition sensors is unacceptable.

Abstract: A torsion damping device provided with an associated friction device. The torsion damping device includes a washer (60) frictionally engaging a disk (11) under axial action of spring lugs (63) bearing on a guiding washer (12B). The washer has a substantially annular shape and acts radially beyond an elastic damping member (15, 15a).

Abstract: A friction clutch has device compensating for wear in the clutch friction wheel and, to a lesser extent, in the pressure plate and reaction plate of the clutch. The wear compensating device is of the type comprising a compensating device arranged between the thrust band and the pressure plate of the clutch, and the thrust band includes an abutment member cooperating with the cover plate for stabilising the position of the diaphragm when the clutch is engaged.

Abstract: A combination pair of jeans and a metallic ornamentation. A substantially rectangular metallic ornament is affixed to a rear portion of a waistband of a pair of conventional jeans in place of the conventional leather label. The metallic ornament may be rivetted to the waist band or it may be adhered to a leather strip which is in turn sewn onto the waistband. A plurality of metallic belt loops may also be provided and attached to the waistband in a similar fashion. The metallic ornament is made of a lustrous material providing an enhanced appearance. The metallic ornament may be engraved with a specific pattern, logo or other text. The metallic ornament may also be formed of a metal anodized to a specific color.

Abstract: A brake shoe assembly is formed by precision stamping a net shaped web blank having a series of tabs projecting outward therefrom and stamping a corresponding table member provided with tab receiving apertures and bending the table member into a semi-cylindrical segment. The web blank and the table are assembled causing the web tabs and table apertures to be interlocked securely locating the parts temporarily prior to the cooperating tabs and apertures being permanently joined together using a hot staking process without any portion thereof extending substantially beyond the outer semi-cylindrical surface of the table.

Abstract: A disc with friction liners for a mechanical clutch. The blades of the disc include, in the region of each zone (4) in which a friction liner is fixed, a slightly raised portion (1), which prevents overflow of the adhesive on to the bending zones (10) that join the central portion (4) to supplementary engagement zones (7).

Abstract: A rolling member fitted into a guide recess and capable of performing a wedge action on a collar of a rotary quill is held by an annular holder in such a manner that the longitudinal movement of the rolling member can be restricted and the outside of the annular holder is rotatably fitted with an annular outer frame for restricting the outward movement of the rolling member, thereby forming a brake main body. By rotating the annular holder by use of a rotation operation member provided in the annular holder, the rolling member is controlled such that it can be restricted and held at an operative position allowing the wedge action or at a non-operative position prohibiting the wedge action, thereby switching the rotary quill to a reversal preventive position or to a reversal allowable position. Also, the brake main body is constructed as detachable one unit.

Abstract: Magnetic forces developed from electromagnets, superconductor magnets, or other magnets, serve as the basic elements to move, control, direct and stabilize ships in locks chambers and canals. Basic requirements include, but are not limited to, a power supply, the magnetic devices and a system for operation and control of the magnetic devices. This process of moving ships through canals and locks chambers will eliminate other, more expensive means currently in use. The magnetic system will speed the process of canal transit because of its simplicity of operation. It will require much less hardware and human resources to operate and maintain. The magnets would be installed in the locks chamber floors. In canals and approach lanes, the magnets could be placed on a substructure at the bottom of the channel using different structural elements depending on the channel's shape, size and dredging needs.

Abstract: A flywheel having to coaxial members, the first member designed to be rotational integral with a drive shaft such as the crankshaft of an internal combustion engine, the second member designed to be connected with a driven shaft such as a gear box. The coaxial members are mounted via a bearing and coupled to each other. The second member forms a reaction plate of a friction clutch having ventilation holes proximate the bearing. The ventilation holes open into the bottom of a groove provided in the second member around the inner edge of the reaction plate radially above the bearing for collecting lubricating agent such as oil escaping from the center of the flywheel.
