Title: Weatherstrip for hardtop-type or framed door windows
Inventor: GLOSSOP DONALD L JR
IPC: B60J10/79
Filed: 1990-11-07
Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a door glass weatherstripping for a motor vehicle.  The weatherstripping comprises a main body portion attachable to a portion of the vehicle; a gap-filling seal portion attached to the main body portion for filling the space between the edge of the surrounding surfaces and the edges of the window; a window positioning portion attached to the main body portion, disposed adjacent the gap-filling seal portion and having a hardness greater than at least the gap-filling seal portion for guiding the window in its uppermost position thereby assuring lateral location of the window; and a gutter forming lip portion attached to the main body portion.  The gutter forming lip portion is flexible so that when the weatherstrip is attached to the vehicle and at least one of the window and the door is open, the gutter forming lip is positioned so that substantially all the water dripping off the portion of the roof or surrounding surfaces where the weatherstrip is attached is prevented from entering the interior of the vehicle.  The weatherstrip section on hardtop-type window systems may be positioned such that it extends around the whole door opening.

Title: Method for removal of ammonia from a gas mixture
Inventor: EIMER DAG A
IPC: C01C1/04
Filed: 1990-02-02
Abstract: The present invention relates to a method of catalytic production of ammonia, where a gas mixture consisting mainly of unconverted synthesis gas, some ammonia, inert gases and possibly also water is recirculated to the synthesis reactor being first freed from the main part of the ammonia and possibly also water by absorption. The gas mixture is brought in contact with a hygroscopic absorption agent having two or more OH-groups for absorption of ammonia and possibly also water. The absorption is carried out at a pressure being substantially the same as the ammonia synthesis pressure, and ammonia being desorbed from the absorption agent at a lower pressure and higher temperature than at the absorption. At least part of the possibly present water is removed from the absorption agent before it is supplied to the absorption column. Preferably it is applied ethylene glycol, diethylene glycol or triethylene glycol alone or in mixture as absorption agent. Possible water can be removed from the absorption agent by inert stripping gas before it is returned to the absorption column.

Abstract: An apparatus and a method for producing pasty paraffin from liquid paraffin comprises the use of an agitator   for   mixing   the   paraffin   during   its solidification within a receptacle.  The viscosity of the paraffin is controlled by the monitoring of the power of a motor driving the agitator.   Also,  an apparatus  is provided for producing candles in bottles from the pasty paraffin produced hereinabove.  The apparatus comprises a filling head which receives  the pasty paraffin  and  a continuous wick.  A device is included for positioning a ferrule on the wick with the filling head being adapted for lowering into the bottle for positioning the ferrule at the bottom thereof and being also adapted to inject pasty paraffin in the bottle for setting the ferrule. The filling head is then retracted slowly from the bottle while injecting further paraffin therein for filling to a selected  level  the  bottle.    While  the  filling  head retracts from the bottle, the continuous wick is made to extend  from  the  bottom  of  the  bottle  centrally  and longitudinally  therein  and,  once  the  filling  head  is fully retracted from the bottle, the continuous wick is cut near or at the top of the bottle, thereby producing a candle in a bottle.

Abstract: A baseband signal processing circuit for a radio communication apparatus has an amplifier for amplifying the amplitude of an input baseband signal, a limiter for limiting the amplitude of the amplified baseband signal, an amplitude detector for detecting the amplitude of the output signal of the amplifier, and a control unit for controlling the gain of the amplifier in response to the output of the amplitude detector. When the amplitude detector detects an amplitude greater than predetermined one, the control unit controls the gain of the amplifier in such a manner as to maintain the output of the amplifier at a constant level. As a result, the output level of the amplifier is prevented from exceeding the limiter level of the limiter. This allows the maximum frequency transition to be set up with no regard to frequency and suppresses distortions regarding signals exceeding the standard frequency transition.

Abstract: A microwave heating apparatus comprises a heating chamber for supporting an object to be heated, a microwave generator for generating microwave energy inside the heating chamber to heat the object, and an infrared radiation thermometer disposed outside the heating chamber.          A probe is disposed inside the heating chamber; the probe being formed of a microwave transparent material.  A fiber cable has a first end connected to the probe and a second end connected to the thermometer.  A lens is fixed in the probe in alignment with the fiber cable, for collecting infrared rays radiated from the object to be heated in the heating chamber and for transmitting the collected infrared rays into the fiber cable.  The collected infrared rays are transmitted through the fiber cable to the thermometer disposed outside the heating chamber, so as to measure an infrared radiation temperature of the object.  Optionally, a purge gas supply source can be disposed outside the heating chamber, with a gas purge conduit connecting the purge gas supply source to the probe.  A purge gas channel formed in the probe and operably connected with the gas purge conduit can release purge gas from the supply source toward the object, so that infrared rays are collected by the lens, while water vapor and/or a decomposition gas generated from the object is removed by purge gas.
