Title: Method and apparatus for placing discrete parts transversely onto a moving web
Inventor: RAJALA GREGORY JOHN
IPC: B65H39/14
Filed: 1995-08-01
Abstract: This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to transferring discrete parts to a continuous web, whether paper, film, composite, or the like.      Specifically, the invention relates to methods and apparatus for taking discrete parts from a source in a taking zone, optionally taking the discrete parts as components of a continuous web, onto a transport head on a transfer assembly, severing the discrete parts from the continuous web if received as part of a continuous web, rotating the transfer assembly about a first axis and correspondingly rotating the transport head about a second axis radial to the first axis, to thereby present the discrete parts to a receiver in a transfer zone, and transferring the discrete parts to the receiver in the transfer zone. The invention includes using a roughened taking section on the transport head, interacting with textured surface on the discrete parts, to hold the discrete parts to the transport head, with optional use of suction through the transport head to assist in holding the discrete parts to the transport head. Novel apparatus is included for delivering suction to and through rotating slip rings.

Title: Flashmemory mass storage architecture
Inventor: ASSAR MAHMUD
IPC: G06F3/06
Filed: 1994-03-23
Abstract: A semiconductor mass storage system and architecture can be substituted for a rotating hard disk.  The system and architecture avoid an erase cycle each time information stored in the mass storage is changed. (The erase cycle is understood to include, fully programming the block to be erased, and then erasing the block.) Erase cycles are avoided by programming an altered data file into an empty mass storage block rather than over itself as hard disk would. Periodically, the mass storage will need to be cleaned up. Secondly, means are provided for evenly using all blocks in the mass storage. These advantages are achieved through the use of several flags, a map (108) to correlate a logical address (308) of a block to a physical address (408) of that block and a count register for each block. In particular, flags (118, 112, 116) are provided for defective blocks, used blocks, old version of a block, and a count to determine the number of times a block has been erased and written and erase inhibit flag.
Patent CA-2162672-A1 (CA)
Inventor: HANSEN LYLE ANDREW
IPC: B65G67/40
Filed: 1994-05-09
Abstract: A truck platform (10) is elevated at one end and then moved rearwardly by pulsation cylinders (30) which slowly accelerate and then rapidly decelerate the platform and truck (12). The abrupt deceleration causes the material in the truck to continue to move rearwardly separating from the truck floor and move out of the truck in a stair step fashion through repeating pulsation.  The angle in which the platform needs to be raised is minimized by the application of pulsation forces to the system thereby improving the safety and ease of unloading the truck.

IPC: G10L19/035
Filed: 1994-07-07
Abstract: A method of transmitting a digital signal that includes frames of frequency coefficients arranged in bands (201), with the frequency coefficients being represented by a number of bits. The method includes generating a class value (203) that corresponds to the energy in a band relative to the average energy in the other bands for each of the bands. When the number of bits exceeds a predetermined threshold (220), the number of bits is reduced (222) to a value that is less than or equal to the predetermined threshold by eliminating those of the frequency coefficients that belong to the bands having the smallest class values. The remaining frequency coefficients are then transmitted (226).
