Title: Method and apparatus for creating concrete blocks with the appearance of natural fossil stone
Inventor: SHOULLDICE ROBERT B
IPC: B28B7/34
Filed: 2002-03-01
Abstract: A generally conventional concrete block is cast using known procedures. After pouring concrete in a mould, or otherwise forming a block, and before the surface of the concrete has set, shaped bodies of ice are randomly placed on the surface or surfaces to be treated and pressed into the surface(s) to desired depths. The ice bodies will melt during curing of the concrete, but not before the concrete has set enough to keep the shape of the indentations made by the ice bodies. Thus, when the concrete block has set completely, there remains a textured surface having a structure similar to that of natural fossil stone. Alternatively, shaped bodies of combustible material are randomly placed on the surface or surfaces to be treated and pressed into the surface(s) to desired depths. The combustible bodies will make the concrete keep the shape of the indentations made by the bodies after the concrete has cured. After curing, the combustible bodies are heated to their combustion temperature and burned away from the concrete surface. Thus, when the bodies have been removed, there remains a textured surface having a structure similar to that of natural fossil stone.

IPC: H04N7/16
Filed: 2002-06-10
Abstract: An access control method is described for an encrypted program transmitted by an operator to a plurality of groups of subscribers, where each group of subscribers has a group key KG, and each subscriber is able to receive from the operator an operating key KT, enciphered by the group key KG for decryption of the transmitted program. The method further involves linking the enciphered operating key KT to a random value R to generate a secret code, transmitting the secret code to subscribers prior to transmission of the encrypted program, and transmitting the random value R to subscribers for calculation of the operating key KT.

Title: Safety device for boiler comprising a time delay protected by an electronic circuit
Inventor: JACOBBERGER CHARLES
IPC: F23N5/20
Filed: 2002-05-17
Abstract: A safety device for an industrial boiler (CHA) including electromechanical relays (RE<SUB>n</SUB>, RS), which are connected in series in order to form an electromechanical safety chain (CH 1 ), and at least one shunt relay (RT<SUB>n</SUB>) which is normally open and mounted in parallel to one of the electromechanical relays (RE<SUB>N</SUB>). The shunt relay is controlled by an automaton (AP 1 ) so that it is closed during a time delay. The shunt relay (RT<SUB>n</SUB>) is provided with a contact that is connected to an electronic circuit (CE<SUB>n</SUB>) and said electronic circuit (CE<SUB>n</SUB>) opens an electromechanical relay (RS) which is mounted in series in the safety chain when the shunt relay (RT<SUB>n</SUB>) is closed for longer than the time delay. Given the arrangement, in the event of an automaton failure, the time delay is ensured by the electronic circuit so that a satisfactory level of safety is guaranteed in relation to the installation.

Title: Bioactive materials, methods of making bioactive materials and method of use thereof
Inventor: DIBENEDETTO ANTHONY T
IPC: A61L26/00
Filed: 2002-10-25
Abstract: A bioactive material is made using fibroin solutions and suspensions that can be used alone or as a composite with particles such as core/shell particles.  The material is designed to support the constructions, repair, regeneration or augmentation of bone and other tissues of the body. The solutions and suspensions can be loaded with core/shell-type particles comprising inorganic core materials that are coated with biodegradable polymers with an outer coating of a calcium phosphate precursor. The fibroin solutions, suspensions, and composites can be injected to fill cavities or to replace missing tissue.  After injection, the materials can produce a scaffold capable of promoting tissue regeneration while degrading. The degradation of the particles, when present, can generate additional porosity within the scaffold and release other compounds in a controlled manner to enhance growth and activation of the cells necessary for tissue repair. The ability to inject the fibroin solutions, suspensions and composites can reduce the need for many types of surgical procedures that are used to replace or repair bone and other tissues.

Title: Arc extinguishing device with a high speed whip
Inventor: CLEAVELAND STEVE A
IPC: H01H9/38
Filed: 2004-06-09
Abstract: Rapid arc extinguishing devices for air break switches have a whip with at least an end portion of nonmetallic material such as fiber reinforced plastic with a conductive path on its surface. The nonmetallic material is a single tapered rod or an assembly of a plurality of rods successively inserted into an outer rod. The conductive path on the whip is of various individual and combination forms of which some include a metal braid, foil, sheath or wound wire. Particular forms of the conductive path on the rod have enhanced durability and arc resistance at the areas of the whip most likely to be subject to arcing with a latch of the device upon switch opening or closing. Further forms of the whip are a combination in which an end portion as described is attached to an all metal base portion that is arranged to include a portion of the whip subject to arcing on switch closing. Another form of device has a latch engaging a whip at a rotating wheel on the latch. Whips with conductors having metal strands are made with strands bonded to the nonmetallic rod surface for greater durability in use. Whips with an all metal base portion have a metal spine within its nonmetallic portion through the joint region between the two portions, to minimize risk of damage to the nonmetallic portion from high stress in that region when such a whip is released from a latch. Also, a latch with a wheel or roller is improved by a design that limits wear of the conductive path on a nonmetallic rod surface.

Title: Intermittent aerosol dispensing valve
Inventor: SHANKLIN DONALD J
IPC: A61L9/14
Filed: 2003-01-22
Abstract: A valve assembly can automatically dispense aerosol content from an aerosol container (12) at predetermined intervals without the use of electric power. A  diaphragm (40) at least partially defines an accumulation chamber (36) that receives gas propellant from a portion of the can (12) during an accumulation phase. Once the internal pressure of the accumulation chamber (36) reaches a predetermined threshold, the diaphragm moves, carrying with it a seal so as to unseal an outlet channel (51), and thereby initiate a spray burst of the main active chemical. The diaphragm (40) assumes its original position when the pressure within the accumulation chamber (36) falls below a threshold pressure.

Title: System for the transfer and detection of gas dissolved in fluid under pressure
Inventor: JOHNSON BRUCE
IPC: B01D69/10
Filed: 2004-10-01
Abstract: A gas separation system suited for extraction of gas dissolved in pressurized fluid. The system includes a semi-permeable membrane in the form of tubing having an inner core volume with an internal support present within the inner core volume. The internal support provides multiple cylindrical supporting surfaces which are presented to the inside tubing wall surface to prevent collapse of the tubing wall against external pressure. Internal supports may include a coil of spring-like configuration fitted coaxially within the tubing; or multiple filaments that form a longitudinal bundle within the core of the tubing. The response time of the system may be enhanced by the presence of an outer tubular conduit surrounding the semi-permeable membrane tubing and providing a flow path for the external fluid to increase the rate of diffusion of dissolved gases through the semi-permeable membrane. Gas pressures may be a sensed, both total and partial, as well as the identity of respective sampled gases.
