Title: Circular saw blade and method
Inventor: ACTERBERG NICHOLAS E
IPC: B23D61/02
Filed: 1996-09-20
Abstract: A saw blade is stamped with a circumferential edge.          At least one deep gullet and shoulder are formed in the circumferential edge. Likewise, a tooth pocket is formed in the circumferential edge. The tooth pocket is defined by a wall, generally radial to circle, on the shoulder, and a shelf substantially perpendicular to the wall. A tooth is secured, ordinarily by brazing, in the pocket such that the thickness of the tooth is substantially equal to the depth of the shelf and the face of the tooth is continuous with the gullet. The tooth may be brazed along its entire lateral edge such that resultant forces in the tooth are transmitted to the body of the blade.  After the tooth is positioned into the tooth pocket, the tooth, as well as a projection of the blade shoulder, are ground off so that the tooth and shoulder are flush with one another. Thus, the tooth longitudinal edge is in complete contact with the shoulder wall maximizing its strength.

Patent CA-2210062-A1 (CA)
Title: Synchronous dma transfer protocol
Inventor: BROOKS JOHN W
IPC: G06F13/28
Filed: 1996-11-12
Abstract: A synchronous DMA burst transfer method is provided for transferring data between a host device and a peripheral drive device connected by an ATA bus. The method provides synchronous data transfer capability in an asynchronous system by having one device in charge of both a strobe signal and a data signal. When a host read or write command (901) is delivered to the drive device, the device decides when to start the synchronous DMA burst (902). For a read command (B), the device requests the synchronous DMA burst, then drives a data word onto the ATA bus (908) after the host acknowledges that it is ready to begin the burst (904 and 906). After the device toggles a strobe signal (910), the host latches the data word on the bus (912). Additional data words can be driven on the bus and the strobe signal can be retoggled to latch additional data words into the host (914). After all data words have been transferred, the burst is terminated and ready to be used for another host command (918).

Title: Combinatorial libraries of substrate-bound cyclic organic compounds
Inventor: DESAI MANOJ C
IPC: C07D491/052
Filed: 1996-05-23
Abstract: The invention relates to libraries of cyclic organic compounds and method of producing and assaying such libraries. According to the invention, each cyclic organic compound is constructed from a starting material in the form of a solid surface derivatized with a starting resin. Compounds are reacted with the resin to add or to form a cyclic group. The reactions are preferably carried out using a split resin procedure so that different compounds can be reacted with a plurality of subamounts so as to increase the size of the library. For example, compounds are reacted with a solid support bound starting resin to obtain a compound which includes an aldehyde functional group wherein the aldehyde compound or compounds reacted with it have substituents which are varied such that a mixture of products is obtained. The invention further relates to methods of producing combinatorial libraries of cyclic organic compounds from substrate bound compounds by cleaving the compounds from the support after synthesizing is completed and to assaying libraries of such compounds.

Filed: 1996-04-04
Abstract: A remote user (18) at a remote (12) computer accesses a computer network (14) via a remote access device (16) coupled (directly or indirectly) to the network (14). The remote access device receives from the remote computer a request for an identifier. The request does not include any information that uniquely identifies the remote computer or the user thereat. In response to the request, the remote access device generates a client identifier that uniquely identifies the remote computer and then provides that unique client identifier to the remote computer. The remote access device can generate the unique client identifier by concatenating a hardware-level address associated with the remote access device (e.g., a Medium Access Control or MAC address) and the current date and time. The remote computer can store the unique client identifier for future use, and the remote access device can use the unique client identifier to obtain services available on the computer network. For example, the remote access device can use the unique client identifier to identify uniquely the remote computer to a server on the computer network which dynamically assigns Internet Protocol (IP) addresses in order to obtain an IP address for the remote computer.
