Title: Stem cell inhibiting proteins
Inventor: CRAIG STEWART
IPC: C12N1/19
Filed: 1992-12-23
Abstract: Proteinaceous molecules with stem cell inhibition activity are analogues of or MIP-1.alpha. which have mutations to prevent or reduce multimer formation beyond certain stages (for example a dodecamer). Aggregate formation is therefore inhibited, and the resulting low molecular weight monomers (or oligomers) have improved solution properties leading to enhanced productivity and greater therapeutic utility as stem cell protective agents, which are useful in tumour therapy.

Title: Improved multi-cavity dielectric filter
Inventor: BLAIR WILLIAM D
IPC: H01P1/208
Filed: 1994-09-29
Abstract: A multi-cavity dielectric filter 30 having a single housing 32 for a plurality of resonant cavities 65. The dielectric filter 30 has a plurality of dielectric resonators 42 placed inside housing 32, instead of in individual housings, wherein the resonators 42 are spaced a quarter wave apart and are electrically isolated from one another by conductive isolation plates 44 positioned therebetween. The isolation plates 44 do not make continuous mechanical contact with the interior conducting surface of housing 32, but rather are spaced from the inner surface 77 of housing 32, thereby making assembly of the filter much simpler than if a solid RF connection had to be made. The resonators 42 are positioned inside the housing 32 between the isolation plates 44 and are supported by low loss, low dielectric constant spacers 46. End walls 59 complete the cavity formation at the termination ends 79 of housing 32. For a band reject filter, the cavities are joined by coupling loops connected to a transmission line while for a bandpass filter, apertures are placed in the isolation plates (44') so as to couple electromagnetic energy between adjacent cavities (65).

Patent CA-2138184-A1 (CA)
Inventor: MEYERS CLIFFORD W
IPC: G01S7/40
Filed: 1994-12-15
Abstract: Three independent signal sources (14, 15, 20) are used to statistically derive the power spectral density of the phase noise content of signals from each of them. This is accomplished by mixing (30) each of the signals two at a time (i.e., signal one with signal two, signal one with signal three, and signal two with signal three) and capturing the resultant difference signals, such as with a waveform recorder (11, 12, 13), for example. A servo electronics loop (25, 26) is used to remove the carrier and any long term signal drift from the resultant difference signals. Statistical analysis is then used to compute the composite power spectral densities of the the resultant difference signals, and to solve for the individual power spectral densities of the original signals. The present system (10) and method (40) uses the mathematical relationships between the three sources that have similar magnitudes of phase noise, to compute the power spectral density of the noise content of signals from each source (14, 15, 20). The present system (10) and method (40) requires a minimum of interconnect hardware and only three inexpensive waveform recorders (11, 12, 13), for example. Furthermore, the size, weight, and cost of producing the present phase noise test system (10) is relatively low.

Title: Device for opening and closing a window, a door, or the like
Inventor: EIKMEIER WERNER
IPC: E05F11/16
Filed: 1995-01-06
Abstract: In a device for opening and closing a window, a casement moves between a closed and an open position with respect to a stationary frame. This is done by means of a longitudinally displaceable toothed rack, which effects the movement of the casement by means of a carrier. In order to obtain a space-saving, easy to operate device, it is proposed not only to move the casement by means of the toothed rack, but also to move a moveable closing element in the frame between its latching position and unlatching position with a stationary carrier located on the frame. Both carriers are connected respectively to the toothed rack by means of an independent coupling, which is rendered effective and ineffective at an associated change-over location. These two change-over locations are arranged in a specific place in the path of longitudinal displacement of the toothed rack, respond to the associated coupling and are automatically effective.
