Abstract: A louvered blind having a first blind assembly defining a first passageway and a second blind assembly defining a second passageway. A rod passes through both the first and second passageways. A first spacer is frictionally secured to the rod and has a portion disposed in the first passageway for securing the rod to the first blind assembly. The rod is fixedly secured to the second blind. The louvered blind also includes a mechanism for rotating the first spacer and a stop mechanism operatively associated with the rod to resist rotation of the rod. In use, the first spacer and the first blind assembly can be rotated simultaneously with the rod and the second blind assembly. The spacer and the first blind can also be rotated when the stop mechanism resists rotation of the rod and the second blind assembly so that the first blind assembly can be rotated independently of the second blind assembly.

Abstract: The invention provides a package for packaging of products which provides evidence of tampering with or adulteration of the product by providing a readily visible indication that any such tampering or adulteration has occurred. The invention in one form provides an inner container which is in turn at least partially covered with a tamper evident packaging material. The packaging material is a tamper evident composite material comprising a photopolymerizable composition layer which is cured and it becomes extremely brittle such that any physical penetration of this packaging material will cause the brittle layer to fracture or shatter. Such shattering will provide a clear indication that penetration of the packaging material has occurred. Also there may be provided an asociated dye which will exhibit a color change when the brittle layer is fractured or shattered.

Abstract: A method for producing an extrusion having a wood grain appearance. A first extruder including a die and a second extruder which includes a housing and a screw is provided, the screw having a portion disposed within the housing and a portion projecting outwardly from the housing. The second extruder is secured to the die of the first extruder by a pipe, the pipe receiving the outwardly projecting portion of the second extruder screw. A first material is extruded through the first extruder die to produce an extrusion and a second material is introduced into the second extruder. The second material is delivered through the second extruder and the pipe means to bond the second material to at least a portion of the surface of the extrusion to provide an extrusion with at least a portion of its surface having a wood grain appearance. An associated second extruder as well as an apparatus for producing an extrusion having a wood grain appearance is also provided.

Abstract: A carrier comprising a lift bar provided on the body of the carrier and movable upward and downward, a connecting member pivotably connected between an upwardly driving cylinder device and the lift bar, an upper claw provided on the connecting member, and a lower claw provided on the lift bar and cooperative with the upper claw for holding the upper rim of a container. The load of the container acting on the lower claw pulls down the upper claw for the two claws to clamp the container upper rim to transport the container as lifted.

Abstract: A charge-based multiplier circuit is provided which generates a charge packet proportional to the product of an input signal and a weight voltage. An exponential pulse is formed which is representative of the input signal. The circuit generates an output charge proportional to the product of the peak magntiude of the exponential pulse and the exponential decay time constant, which is represented by the weight voltage. The output charge can be generated as a charge onto an output bus for positive results, or the amount can be depleted from the bus for negative results.

Abstract: A method and apparatus for determining carbon content in fly ash providing a source of fly ash and a microwave interrogation chamber. A quantity of fly ash is introduced into the interrogation chamber and exposed to microwave energy. The amount of carbon in the fly ash is determined by measuring the amount of microwave energy exposed to the fly ash, the amount of energy transmitted through the fly ash, and the amount reflected therefrom in order to determine the amount of energy absorbed. The concentration of fly ash is preferably determined by determining the weight of the fly ash and determining the percentage of carbon content in the fly ash. The method is particularly useful in respect of monitoring carbon content in fly ash of boiler exhaust gases. The system may also be employed to determine the fly ash glass content of fly ash.

Abstract: Apparatus for altering the output of an electronic string musical instrum responsive to bending of the string comprises a compressible electrically conductive member which has an electrical resistance which varies with the degree of compression applied and may be a conductive elastomer or a piezoresistive material. First and second holders are in contact with the conductive member and a current source is secured to the first holder and the string electrode secured to the second. Bending of the string causes the application of compression to the conductive member. The change in current flow is converted into an output which is a frequency variation which corresponds to the degree of bending of the string.
