Abstract: The present invention relates to an improved locking mechanism for blade of coping saw. The free ends of the upper and lower swinging arms of the coping saw is removably disposed with an upper and lower fixing blocks respectively for mounting and bridging a blade therebetween. The blade of general type can be readily bridged and supported between the slits of the upper and lower fixing blocks in usual manner: In assembling, the blade can be suitably disposed between the slit of the upper fixing block and the slit of the lower fixing block. Then a locking screw is suitably passed through the traverse hole of the slit and engaged into the threaded hole. As a result, the upper end of the blade is fixedly attached to the upper fixing block. Similarly, another locking screw is applied and which is passed through the traverse hole of the slit and is finally engaged into the threaded hole. As a result, the lower end of the blade is fixedly attached to the lower fixing block. In case a variant of the blade which has a cross portion at both ends is used, it can be also attached to the upper and lower fixing blocks. In mounting, the upper end of the blade is disposed within the slit such that the cross end is firmly seated onto the upper concave portion. Then a locking screw is applied and which passes through the through hole of the upper block and finally locked into the threaded hole. As a result, the upper end of the variant blade can be suitably supported and locked. Similarly, the lower end of the variant blade is also attached to the lower fixing block in the same manner as the upper end. By this arrangement, the variant blade is fixedly bridged between the upper and lower fixing blocks. By this arrangement, since the variant blade can be fixedly and firmly supported between the upper and lower fixing blocks, the oscillated cutting movement of the variant blade can be more efficiently and smoothly performed without any possibility of removing therefrom. As a result, the existing blades can be suitably disposed and supported between the free ends of the upper and lower ends of the upper and lower swinging arms for cutting movement.

Abstract: A process for color overprinting onto a thermally printable receiving surface (20) includes using a thermal printer (10) and transfer foils (24) to print a first layer of color printing medium (42) onto a portion of the receiving surface, and then using the thermal printer to print at least a second layer of translucent colored printing medium (44) onto the receiving surface on top of the first layer.  An index of overprint colors (46) can be created by the process for use in matching colors printable by the overprinting process to the colors on an original graphic.  The index may be used manually or in a computerized printing process to determine the number of transfer foils required to reproduce an original graphic, and their order of use.

Abstract: Methods for treating glutaraldehyde-fixed collagenous tissues to mitigate their propensity for subsequent calcification and to improve durability. Collagenous tissues which have been harvested and cross-linked b y glutaraldehyde are exposed to a carboxyl activating agent to convert the free carboxyl (COOH) groups of the collagen molecules to activated carboxyl moieties (e.g., o-acylisourea). Thereafter, the collagenous tissue is exposed to a compound capable of reacting with the activated carboxyl moieties (e.g., o-acylisourea) to form non-carboxyl side groups. Monofunctional and multi-functional amines are examples of compounds which may be utilized to react with the activated carboxyl moieties to form such non-carboxyl side groups. Thereafte r, the collagenous tissue is again exposed to glutaraldehyde. If the non-carboxyl side groups have functional amino groups (NH2), such additional exposure to glutaraldehyde will result in additional glutaraldehyde cross-linking of the collagen molecules and resultant improvement of durability.

Abstract: A system interconnection device connected between two systems, such as a commercial bus line carrying power from a commercial power line and a private bus line carrying power from a private power generator, is able to connect and disconnect the two systems, and, in the event of a fault, has a current-limiting effect, thus preventing instantaneous voltage drop of the respective bus lines. In the system interconnection device, unit parallel circuits made up of diodes and DC reactors are serially connected so that the diodes thereof have opposite directions. With this structure, in realizing operations equivalent to those of a conventional system interconnection device having a DC reactor between DC terminals of a single-phase rectifying bridge circuit, the number of diodes, which are rectifying elements, can be halved. This not only enables reduction of the total cost of elements, but also, particularly in high-voltage and extra-high-voltage systems, enables great reduction of the cost and space devoted to insulation.

Abstract: A system for determining when a radio telecommunications network should swit ch between a first grade of service and a second grade of service based upon a highly accurate and reliable estimate of the b it error rate BER. The system estimates (65) the BER on an uplink and a downlink on a user channel, and determines (66) whether the BER on the uplink and the downlink on the user channel are below a first set of thresholds. The system then measures the residual SFET RBER and the frame erasure rate FER on the voice channel uplink, and determines (74) whether the downlink BER, the uplink RBER, and t he uplink FER are lower than a second set of thresholds. If lower, the system sends and receives a data message on a Fast Associated Control Channel (FACCH). The system obtains a highly accurate estimate (83) of the BER on a downlink on the FACCH channel, and reports (88 ) the downlink BER in a message on the FACCH channel uplink. The system then estimates the BER on the FACCH channel uplink. Finally, the system switches the radio telecommunications network from the first grade of service to the second grade of service in response to determining that the uplink and downlink BER on the FACCH channel are below a third set of thresholds.

Abstract: A method for mapping a work (e.g., a picture, a document or the like) comprising a large number of bytes into a relatively small bit string to facilitate copy protection. The technique creates a first string from the work with the property that if one modifies the work by some given degree (e.g., through intentional variation or perhaps merely through aging), a second string (generated by the inventive technique) and associated with the modified work is not meaningfully distinct from the first string. When applied through the algorithm, works that are similar result in the same or similar strings. As a result, an owner of the content sought to be protected may apply the algorithm to copies of the work for copy protecti on purposes.
