Patent CA-2153114-C (CA)
Inventor: WILCOX STEPHEN H
IPC: B65D90/24

Granted: 1997-04-08
Abstract: An above-ground secondary containment unit for storage tanks is comprised of a rigid base and upwardly extending side and end walls.  Side cover shields are mounted to the top of the side walls by way of hinges and are intended to contact a side surface of the storage tank thus minimizing or preventing the entry of precipitation or debris into the unit while the tank is in place.  End cover shields are mounted to the top of the end walls using a nut and bolt arrangement and slots in the shield allowing for lateral adjustment of the shields with respect to an end surface of tanks of varying sizes and configurations.  These shields similarly minimize or prevent the entry of precipitation and debris into the unit.  The walls of the unit are tapered so that one unit may be nested within another similarly shaped unit for convenient storage and to permit shipment of multiple units at the same time.  Linear tie-down straps are mounted to one side wall and extend across the top of the unit to the other side wall in order to secure a tank in place.  The whole unit may be mounted on skids to allow transport either alone, or in combination with a tank secured by the tie-down straps.

Abstract: An electrically operated line valve has its outlet connected to the inlet of the manifold for supplying the user actuated individual gas burner valves and a user actuated line power switch is closed before opening of any of the burner valves. A valve position detector signals an electronic controller which supplies power to the line switch only if a burner valve has been opened after closing of the line switch. A user actuatable manual override cable enables the line valve to be manually opened during periods of electrical power outage.

Abstract: The adhesive bonding strength of a pressure sensitive adhesive on a laminate is selectively modified by applying a discontinuous layer of a non-adhesive material to the pressure sensitive adhesive.  Preferably, the laminate is a preformed, label stock, including a label or substrate having a pressure sensitive adhesive on one surface thereof and a release sheet overlying the adhesive.  The label is first delaminated from the release sheet to expose the oppositely facing surface of the label and the release sheet.  A discontinuous layer of the non-adhesive material is  then  printed  on  either  the  release  sheet  or  the adhesive.  The release sheet is relaminated back onto the label  to  form a  modified  laminate  with  new  adhesive properties.   When the label is then separated from the release layer, the non-adhesive material adheres to the pressure sensitive adhesive to reduce the exposed surface area of the adhesive.

Title: Information encoding method and apparatus, information decoding method and apparatus, information transmission method, and information recording medium
Inventor: TSUTSUI KYOYA
IPC: G10L25/93
Filed: 1995-03-31
Granted: 2005-09-20
Abstract: According to the present invention, for encoding input signals, the input signals are transformed into frequency components, and the frequency components are separated into a first signal composed of tonal components and a second signal composed of other components. The first and second signals are encoded respectively, and code strings for transmission or recording are generated on the basis of encoded signals resulting from first and second encoding. For example, only the first signal is encoded and the code string is caused to include partial information strings grouped so as to have common values on the basis of at least one of reference parameters pertaining to the signal separation and parameters pertaining to the first encoding. Thus, more efficient encoding than in the conventional technique can be realized.

Abstract: A transmittal signal is transmitted in a forward error correction format in casethe length of the transmittal signal satisfies predetermined conditions but not in a forward error correction format in case the length of the transmittal signal does not satisfy the predetermined conditions. Owing to this arrangement, a long signal susceptible to errors, can be encoded in a forward error correction format. For transmitting a short transmittal signal, wasteful consumption of transmission data capacity of a radio channel can be prevented.

Abstract: An aqueous solution containing valine is reacted with p-isopropylbenzenesulfonic acid or a water-soluble salt thereof to form valine p-isopropylbenzenesulfonate crystals. The valine p-isopropylbenzenesulfonate crystals are separated from the solution and the valine p-isopropylbenzenesulfonate is then dissociated to obtain valine having a high purity. Since the solubility of valine p-isopropylbenzenesulfonate is low, valine can be obtained in high yield. The valine p-isopropylbenzenesulfonate in crystal form obtained in the process of the invention and comprising 1 mole of valine and 1 mole of p-isopropylbenzenesulfonic acid represents a novel product.

Abstract: Likelihood calculating circuit A1 calculates the humming distance between a received data series and a unique word as likelihood data d1. Likelihood calculating circuit A2 calculates the number of transmission errors using redundant data, and outputs this value as likelihood data d2. Likelihood data d1,d2 are added at adding circuit 21, and the output thereof is compared to the threshold value of determination circuit with threshold 22. The results of this comparison are output as determination signal with threshold DT. Synchronous determination circuit 23 generates a synchronous determination signal SD based on determination signal with threshold DT. Accordingly, the present invention provides a frame synchronization circuit in which it is possible to avoid out of synchronization or false synchronization, without increasing the amount of redundancy necessary to detect frame synchronization.
