Abstract: A skate sharpening apparatus is disclosed having top surface (20) and a grinding disc (21) rotatable about a vertical axis above the surface. A  bearing body (23, 28) having a free slide support (23) and a blocking section (28) is secured to the surface (20) slidably supports a guide bar (24). The blocking section (28) can be selectively fixed to or released from the guide bar. It is connected to the support (23) by an adjusting device moving the section (28) relative to the support (23) in fine increments. The front end (24b) of the guide bar (24) carries a pivot (34) supporting a lateral arm (35) for swinging about a horizontal swing axis (34a). The free end (36) of the lateral arm (35) carries a dressing tool (37, 37a) with rearwards directed dressing tip. The tool is slidable but can be fixed relative to the free end (36). The calibration of the desired radius of dressing the disc (21) is effected by abutting the dressing tip (38) against the disc (21) while the tip (38) coincides with the swing axis (34a) and then sliding the guide bar (24) by a distance corresponding to the desired radius and then fixing again the tool (37) to the free end (36). A digital or mechanical scale (27) at the support (23) is used in this adjustment. The invention presents an improved dressing tool where the measuring and adjusting elements are removed from the area where the debris released by the dressing might soil them. The caliration of the dressing radius is simpler than in previously known devices.

Title: Universal transfer method and network with distributed switch
Inventor: BESHAI MAGED E
IPC: H04L12/56
Filed: 1999-08-06
Abstract: A method and a network for a universal transfer mode (UTM) of transferring data packets at a regulated bit rate are disclosed. The method defines a protocol that uses an adaptive packet header to simplify packet routing and increase transfer speed. The protocol supports a plurality of data formats, such as PCM voice data, IP packets, ATM cells, frame relay and the like.      The network preferably includes a plurality of modules that provide interfaces to various data sources. The modules are interconnected by an optic core with adequate inter-module links with preferably no more than two hops being required between any origination/destination pair of modules. The adaptive packet header is used for both signaling and payload transfer. The header is parsed using an algorithm to determine its function. Rate regulation is accomplished using each module control element and egress port controllers to regulate packet transfer. The protocol enables the modules to behave as a single distributed switch capable of multi-terabit transfer rates. The advantage is a high speed distributed switch capable of serving as a transfer backbone for substantially any telecommunications service.

Title: Ic card system, transportation system, and communication equipment
Inventor: OKADA HIROHARU
IPC: G06K19/077
Filed: 1998-01-30
Abstract: A transportation system constituted of moving bodies (40 and 40') which have no power source, but move by obtaining electric power by receiving and rectifying radio waves and to which non-contacting type IC cards (10a and 10a') are respectively attached, an interrogator main body (20) which has an antenna section (21b) for transmitting radio waves and data and communicates data with the cards (10a and 10a'), and a movement controller (30) which controls the moving directions of the moving bodies (40 and 40') in accordance with control signals from the interrogator main body (20). The antenna section (21b) is attached to the responding body section (21a) of a responding section (21) which responds when the section (21) comes into contact with the moving bodies (40 and 40'). The distances between the cards (10a and 10a') attached to the moving bodies (40 and 40') and the antenna section (21b) of the interrogator main body (20) can be remarkably shortened as compared with the conventional example regardless of the shapes and sizes of the moving bodies (40 and 40'). When it is contrived to supply the necessary minimum radio waves to the IC cards (10a and 10a') which make data transfer from the antenna section (21b), the data transfer can be performed efficiently. In addition, a transportation system which is almost free from interference can be obtained.
