Patent CA-2086185-A1 (CA)
Title: Dual Stator Winding Connection
Inventor: HERZOG GORDON W
IPC: H02K3/28
Filed: 1992-12-23
Abstract: There is disclosed a dynamoelectric machine having a dual stator winding comprising a pair of windings each connected in a three phase star configuration from a respective neutral. The three phases of each of the pair of windings are normally displaced from each other by 30 electrical degrees. The improvement includes first and second terminals at the midpoint of each of the three phases of each of the pair of windings which terminals are normally connected to each other. This allows the dynamoelectric machine to be connected to a twelve pulse LCI source.      Alternatively, the first terminal of each three phase windings may be connected to the second terminal of its corresponding phase winding to provide cross connected windings having zero electrical degrees displacement. The line terminals of the corresponding cross connected windings may be connected to a conventional power source.

Patent CA-2087267-A1 (CA)
Inventor: BASS STEVEN H
IPC: G01N33/76
Filed: 1991-08-16
Abstract: 2087267 9203478 PCTABS00010 Novel methods are disclosed for modulating the action of polypeptide hormones on mammalian cells, organs or whole mammals.  Polypeptide hormone action is controlled by effecting the binding specificity of the polypeptide hormone for distinct receptors. The specificity for the receptor is mediated by the ability of a metal ion to complex between the polypeptide hormone and its receptor.  Soluble variants of the hormone receptor may be used to modulate the action or serum half-life of the complexed polypeptide hormone.  An example of such a polypeptide hormone system is human growth hormone (hGH) wherein receptor specificity is modulated by the metal cofactor zinc. Under low zinc conditions, hGH preferentially binds to human growth hormone receptor or binding protein, under high zinc conditions, hGH preferentially binds to human prolactin receptor or soluble prolactin receptor variants. This is the first indication that a metal ion can mediate a direct interaction between a polypeptide hormone and an extracellular receptor or binding protein.

Title: Arrangement for protecting telecommunictions equipment from voltage transients
Inventor: ATKINS IAN PAUL
IPC: H02H9/00
Filed: 1991-09-27
Abstract: An arrangement for protecting an electrical circuit such as a telephone circuit from a voltage transient comprises a voltage clamp or foldback device (3) arranged to be connected between a current-carrying line (1) and ground (1'), a capacitor (2) in seri-es with it, and an inductance (4) series connected in the line. During normal operation the arrangement acts as an LC filter whose high frequency break-point is determined by the capacitance of the voltage clamp or foldback device (3) and the value of the in-ductance (4) which are chosen to give a break point of 1 kHz to 10 MHz.  However, when the arrangement is subjected to a voltage transient, the voltage clamp or foldback device (3) fires causing the break-point to fall to a value determined by the values of the capacitor (2) and inductance (4). The arrangement may be used, for example, to protect the circuit against a rapid voltage drop caused by the firing of another circuit protection device such as a gas discharge tube (5).
