Filed: 1995-05-18
Granted: 2010-11-30
Abstract: A transgenic animal model for arthritis is disclosed. The arthritic condition results from genetic (or immunologic) manipulations that result in the T cell receptor (TCR) repertoire of the animal being substantially limited relative to the TCR repertoire of a wildtype control animal. The TCR repertoire of the arthritic animal, albeit limited, is functionally viable. In a preferred embodiment, the invention relates to transgenic arthritic mice wherein arthrids results from (1) a transgenic allele which encodes and expresses TCR .alpha. and .beta. subunits that combine in T lymphocytes of the transgenic animal to form a TCR that recognizes an antigen comprising one or more epitopes of an oligopeptide derived from amino acids 41-61 of bovine pancreatic ribonuclease and/or (2) polypeptide arthritogenic self antigens derived from endogenous proteins. The transgenic arthritic mice of the invention provides an animal model which faithfully mimics rheumatoid arthritis and by which human arthritogenic and therapeutic anti-arthritic compositions are evaluated. Also provided herein are therapeutic oligopeptides derived from the variable regions of the TCRs of the transgenes of the invention and/or from the amino acid sequence of proteins comprising endogenous polypeptide arthritogenic antigens.

Abstract: A handshake between sending and receiving devices (10) that exchange DTMF signals across a network (14) is accomplished by having the receiving device send a DTMF ready tone (digit) for a prescribed interval following receipt of a call set-up message received after the sending device has initiated a call. Upon receipt of the DTMF ready digit, the sending device sends to the receiving device a data message includes a string of digits of interest prefixed by M header digits. After receiving at least a portion of the data message, the receiving device stops transmitting the ready digit. Once the receiving device has received the entire data message, the receiving device strips the protocol digits (the M header digits and any of the ready digits received due to echo). By analyzing the stripped protocol digits, the quality of the handshake between the receiving and sending devices can be determined.

Abstract: The claimed pneumatic wing has a continuous, airtight envelope (8) made of a textile base material and subdivided into cells (15) by a plurality of textile webs (3). The envelope (8) forms a top skin i (1) and a bottom skin (2), such that the top skin (1) in part (towards the down-draft edge (5)), the bottom skin (2) entirely or in part, can be supplemented by an upper and a lower double-skin (16, 17). The double-skins (16, 17) are connected to the envelope (8) between the attachme nt lines of the webs (3), thus forming between the envelope (8) and double skins (16, 17) channels (19) to which compressed air can likewise be admitted. This changes the shape of the wing profile. In addition, the webs (3) can in part have a similar airtight and double- walled design, here too creating channels (19) to which compressed air can be admitted. This reduces the height of the wing profile. With a suitable combination of these options, part of the wing can be designed as aileron or landing flap, or the wing as a whole can be optimized with respect to the selected flying speed.

Abstract: An electric shaver including a display that indicates when it is time to clean the shaving debris accumulated on a shaving debris receiving part that is covered by an outer cutter frame of the shaver. A counting device of the shaver counts the use time (or the load current) of the motor that drives the inner cutter so that a control device compares the counted use time with a preset reference value; and when the counted use time reaches the preset reference value, the control device judges that the time for cleaning has arrived and actuates the display so that the display shows that it is time for cleaning Thus, the user detaches the outer cutter frame and removes the shaving debris from the shaving debris receiving part in which a light-receiving devices is embedded. When the shaving debris is removed and the light exceeding a preset light quantity impinges on the shaving debris receiving part, the control device detects via the light-receiving device that light exceeding the reference quantity of light has impinged on the shaving debris receiving because of the removal of the shaving debris; as a result, the control device resets the counting device so that the counting device re-starts the count of the use time.
