Title: Spray-protected connection housing for electrical consumers
Inventor: SCHULTE SIEGFRIED
IPC: H02G3/08
Filed: 1990-11-14
Granted: 1995-10-03
Abstract: An adapter box having a base structure that has an annular sealing ridge on the cover side and with a cover that has a sealing effect with an annular sealing strip in conjunction with the sealing ridge.  The technical problem is complete sealing of the adapter box in the area of the cover and of a connector so that jet-proofing is attained.  The sealing strip has a trough-shaped section overlapping the sealing ridge, and the sealing ridge has two tongues separated by a gap.  Each window formed as a cutout in a wall has a contour consisting of straight sections and centric arc sections with the same radius, which together form in each case a one nth partial arc, with n = 3, 4 ...., of the full arc.  The collar of the sealing flange has an external contour identical with the contour of the window.  The neck of the sealing flange has in each case partial sections extending over one nth partial arc from one arc section starting from the centre of a straight section and a straight section running at a tangent to it.

Filed: 1991-07-15
Granted: 1998-05-05
Abstract: An improved control shaft seal and air valve for a portable paint gun with the seal having a radial clearance with the shaft except at a shaft sealing surface of limited axial length.  The shaft seal has a conical surface radially outward of the shaft sealing surface to provide a sealing surface and also to provide transfer of axial forces at that surface to a radial direction to provide a force to urge the shaft sealing surface against the control shaft.  A second conical surface of the seal provides for retention of the seal on an air valve spring when the paint gun is disassembled.  An improved air valve for portable paint guns is also disclosed having a rigid axial hub and radial support carrying a relatively flexible rim portion adapted to engage a tapered seating surface in the gun.

Granted: 2001-05-08
Abstract: An off-premises negative or positive trap jamming cable television or interdiction system includes a picture carrier controlled automatic gain control circuit (231). A broadband television signal output of a variable gain device (230) is distributed by a radio frequency signal splitter (280) to a number of subscribers. A portion of the output of the variable gain device (230) comprising at least two contiguous television channels is passed to a power level detector (502). A detected power level is compared with a predetermined power level reference (504) for adjusting the gain of the variable gain device (230). The predetermined power level reference is set to equal the attenuation between the off-premises equipment and the subscriber premises plus the desired level at the entrance to the subscriber's premises. The power level of a jamming or interdicting signal for denying access to unauthorized television programs is set to fall within a predetermined range of power levels related to the predetermined power level reference.

Patent CA-2080974-C (CA)
Inventor: CETINKAYA ISMAIL BIRKAN
IPC: B01D45/12
Filed: 1992-10-20
Granted: 2004-02-17
Abstract: A method and apparatus for an FCC process uses dissipator plates at the outlet of a disengaging vessel to provide a quick separation of catalyst from product vapors and to prevent reentrainment of catalyst by stripping gas which is passed into the disengaging vessel. The process and apparatus use a riser for the conversion of an FCC feedstock and direct the effluent from the riser directly into a disengaging vessel to separate catalyst from the product vapors. Catalyst is directed downwardly out of the outlet of the disengaging vessel and through a series of dissipator plates that eliminate the tangential velocity that would be otherwise introduced by the vortex and would lead to reentrainment of catalyst. The dissipator plates are located in a stripping vessel positioned immediately below the disengaging vessel outlet to receive catalyst as it leaves the disengaging vessel.

Abstract: A system for the transmission of information between elements of a data processing complex  and a method for establishing  such  a  system.    Two  elements  of  a  data processing  system  are  connected  by  a  physical  link comprising multiple conductors attached to transceivers at channels  in  each  data  processing  element.    Once  the transceivers have been synchronized, commands and responses are exchanged which ensure that all of the transceivers in a channel are connected to the same channel on the other end of  the  conductor.   If  the  transceivers  are  considered configured and an entry is made in a Configured-Transceiver table.    A search is made of an Allowed-Operational-Link table which contains sets of transceivers which are allowed to become operational links.  The set of transceivers thus found, is compared against the Configured-Transceiver-Table to verify that all of the members of the set have been configured.   If a match is found, this set of transceivers becomes       an       Intended-Operational-Link.        The Intended-Operational-Link is verified to ensure that both channels  agree  on  the  set  of  conductors  will  form  the operational   link.     If   the   Intended-Operational-Link verifies, the operational link is established therefrom.

Granted: 1997-03-18
Abstract: A linear and symmetrical gigaohm resistive load structure for an integrated circuit is implemented using a thin film accumulation mode MOSFET configured as a split gate symmetrically off device.  Preferably, the resistive load structure comprises two thin film accumulation mode field effect transistors connected in series with a common node and separate gate electrodes.

Title: Steam cooling of gas turbine with backup air cooling
Inventor: CHEN ALLEN G
IPC: F01K23/10
Filed: 1995-04-27
Granted: 2004-06-01
Abstract: A gas turbine power plant in which a mixture of steam and compressed air, the mixture being primarily steam, is used to cool the rotating blades and stationary vanes in the turbine section. The air is bled from the compressor. The flow rate of steam that is mixed into the compressed air is adjusted so to maintain the pressure drop experienced by the compressed air as it flows to the turbine within a predetermined range. Consequently, the steam and air mixture has the same volumetric flow rate as if compressed air alone were being used. Thus, any sudden decrease in steam flow rate will automatically result in an offsetting increase in the flow of compressed air due to the decrease in the line pressure in the common line through which the air and steam flow to the turbine. Consequently, no control, isolation or check valves are utilized in the compressed air piping.
