Title: Cushion element for detonators and the like; apparatus and method of assembly
Inventor: GLADDEN ERNEST L
IPC: F42C19/08
Filed: 1991-03-21
Abstract: An improved detonator is disclosed having a cushion element disposed within a channel of the detonator housing.  The element is provided with a resilient, pliable and shock absorbant surface for contact with, and retention of explosive material in the detonator housing.  A barrier-type signal communicating surface is formed on the element for communicating an initiating signal to the explosive material.       A method is disclosed for assembling a detonator which includes inserted explosive material into an axially extending channel of a detonator housing, inserting a cushion element having a signal communicating surface into the channel, and pressing the element towards the enclosed end of the housing for compacting the explosive material between the element and the housing closed end.

Title: Method and apparatus for recovering parity protected data
Inventor: BOND MILTON F
IPC: G11B20/18
Filed: 1991-06-13
Abstract: A storage management mechanism resident on a storage controller maintains parity records on the storage units it services.   The  storage  management  mechanism  includes  a status map indicating, for each data block, the location of the corresponding parity block, and the status of the data block.  If a single storage unit fails, the system continues to operate, and the storage management mechanism is placed in a failure operating mode.   While in failure operating mode, the storage management mechanism checks the status map before accessing data on the failed storage unit.   If the data has  not  yet been  reconstructed,  storage  management first reconstructs the data in that block of storage by successively reading and accumulating an Exclusive-OR of the same blocks  on all  storage  units  in  the  parity  group, including the parity block. The block of reconstructed data is  stored in the location of the parity block,  and the status map is updated to indicate that the block has been reconstructed.  Once the data has been reconstructed, it is only necessary to read from or write to the former parity block directly.  In the same manner, storage management will reconstruct a block of storage on the failed unit before writing to any corresponding block on a non-failed unit, if the block has not yet been reconstructed. In an alternate embodiment,  spare  areas  of  storage  in  the  non-failing storage units are allocated to the reconstructed data.  The total  of  these  spare  areas  constitute  a  virtual  spare storage unit.  As data is reconstructed, it is placed in the virtual spare unit, and parity is maintained in the normal fashion.

The other end of the wall of the junction box is sealed by means of a fitted lid which is held secure to the box by means of two screws. Each tubular projection, being dimensioned internally to receive an end of an electrical conduit, contains a "Knock-out portion at the end forming a portion of the wall of the box, which seals the opening of the tubular projection at the wall of the box. This "Knock-Out" portion when removed creates a ring on the interior of the tubular projection, which is wedge shaped, forming a locking device permitting an electrical to be inserted into the tubular projection, and having been inserted cannot be withdrawn. There are locations on the interior of the box at which interconnecting grounding wires and fixtures can be adhered to. The lid, which seals the open of the box, has a lip, which fits within the interior of the walls of the box. This lip is wedge shaped at the edges and engages the conduit when the lid is placed on the box in such a manner that further restricts the conduit from being withdrawn.

Title: Process of worm farming and large scale composting which uses discarded tires as composting and worm propagation silos
Inventor: WOODS TIMOTHY J
IPC: A01K67/033
Filed: 1993-07-23
Abstract: Abstract: Dyke and Levee Agriculture -a process of worm farming and large scale composting that incorporates the recycling of discard tires as worm propagation silos. Discard tires may be converted into worm cultivation silos be carefully selecting and stacking them into relatively well sealed vertical chambers.  Each chamber, or silo, may them be loaded with biodegradable compost, earth, and worm/cocoon culture.  If the silo is serviced properly (given adequate compost feed, and moisture, and protected from predators), the silo will produce a perennial crop of worms and high quality soil.  The silo may be dug into the ground, or may be begun at ground level and built up from there - a preferred choice over ground of marginal value, and where labor and machine costs are high.  The silo may be used as a single unit, or in line with many other similar worms silos, or as part of a matrix (levee) of silos in banks of earth of standardized dimensions.  Where may levees of silos are being used, service lanes (dykes) are placed between them at regular intervals.  These dykes are used by the vehicle that will carry/pull shredded compost forage/feed to the silos, and will collect earth and/or worm culture, and for related machinery (forage blower, hopper, irrigation implements). The dykes also insure that if a fire were to ignite, it would be reached  quickly; and then be either extinguished, or separated from other combustible materials, almost immediately.
