    摘要: A scroll saw is disclosed having upper and lower reciprocable arms terminating in upper and lower ends having a saw blade connected therebetween. A releasable blade tensioning device is mounted on the upper end including a blade support member having a central portion pivotally mounted to the upper end with a first end thereof extending along the upper arm and a second end connectable to the saw blade. The blade support member is pivotable between a first blade tensioning position and a second blade tension releasing position, and a manually rotatable cam is mounted on the first end and a manually operable adjustment screw engageable therewith is mounted on the upper arm. The manually rotatable cam is constructed and arranged to force the first end and the upper arm apart in one rotated position thereof to move the blade support member to the first position, and to permit the blade support member to move to the second position in another rotated position thereof. The manually operable adjustable screw permits adjustment of the tension on the saw blade.

    摘要: The present invention relates to a process for the preparation of 4-(6.sup.1 -methoxy-2.sup.1 -naphthyl)butan-2-one and to certain compounds for use in that process.British patent specification No. 1,474,377 discloses inter alia that 4-(6.sup.1 -methoxy-2.sup.1 -naphthyl)butan-2-one possesses useful anti-inflammatory activity. A particularly favored process has now been discovered that can be used to produce 4-(6.sup.1 -methoxy-2.sup.1 -naphthyl)butan-2-one in particularly good yield.The present invention provides a process for the preparation of 4-(6.sup.1 -methoxy-2.sup.1 -naphthyl)butan-2-one which process comprises the hydrogenation of a compound of the formula (I): ##STR1## wherein Ar is a 6-methoxy-2-naphthyl group; X and Y are each hydrogen atoms or together represent a second bond between the carbon atoms to which they are attached; and R is a group such that --CO.sub.2 R represents an ester group convertible by hydrogenation to a CO.sub.2 H group.

    摘要: A system and a method for controlling an electronic device embedded in a package of a consumer product are disclosed. In one aspect, the consumer product packaging includes a bottle for a beverage, a memory, a receiver and a circuit. The memory stores an action to be performed in response to an input. The receiver receives the input indicative of movement of the bottle. The circuit retrieves the action stored in memory upon receipt of the input and command an electronic communication module to perform the action at a particular time or in a particular sequence.

    摘要: A stand includes a frame and a mounting mechanism coupled to the frame. The frame includes a first platform disposed at a first end of the frame and extending along a proximal direction relative to the frame. The frame includes a second platform disposed at a second end of the frame, the second end opposing the first end. The second platform extends along the proximal direction relative to the frame and is configured to translate relative to the first platform between a first position and a second position to dispose the second platform at a vertical distance of between about 24 inches and 36 inches relative to the first platform. The stand includes a seat portion coupled to the second platform, the seat portion configured to rotate relative to, and about a proximal perimeter portion of, the second platform between a first seat position and a second seat position.

    摘要: A spectroscopic sensor and a spectroscopic method of determining a concentration of a sample are disclosed. The sensor is used in connection with a sample cell containing a sample. The sensor includes a coherent light source configured to transmit an interrogation light beam along an optical sample path directed towards the sample. The sensor also includes an in-line reference cell located in the sample path. The sensor also includes a detector having outputs responsive to absorption signals from the sample and the in-line reference cell. The sensor also includes a processor configured to isolate the reference absorption signals from the in-line reference cell and sample absorption signals from the sample cell and generate calibration information based on the reference absorption signals and determine a concentration of the sample based on the sample absorption signals.
