Inventor: DIETEL DALE G
IPC: B30B9/30
Filed: 1996-02-29
Abstract: A two-stage compaction device for compressing residue metal waste and squeezing excess fluid from the waste, having a pre-compaction cylinder, a pair of compaction chambers, and a pair of die cylinders, all aligned along a common horizontal axis; each of the compaction chambers has an ejection plunger and ejection slot for removing compressed pellets of metal waste and for draining excess fluid accummulations.  The pre-compaction cylinder and the die cylinders have pistons within the compaction chamber, and the actuation of the pistons is controlled to first compress residue waste material in one compaction chamber and then to compress residue metal waste material in the other compaction chamber while the ejection plunger is activated in the first chamber to eject the previously compressed pellet.

Abstract: Portable car coffee warmers have previously been developed for keeping coffee warm.          These portable car coffee warmers however have a number of problems.   The first problem is finding a "safe and convenient" storage place when the coffee warmer is not in use. The second problem is finding a "safe and accessible" surface in close proximity to the power source on which to place the coffee warmer. The third problem is the possibility of a fire resulting from the non-permanent coffee warmer being left on for extended periods of time.   In this invention all of the above inconveniences and safety hazards have been addressed. A number of additional features have also been added. The Built-in Car Beverage Warmer and Baby Bottle Warmer Attachment is intended for maintaining the comfortable drinking temperature of warm beverages such as coffee, hot chocolate, baby milk etc. while at the same time being convenient and safe.   This invention essentially is comprised of built-in cup holders built-in heater units, safety circuitry and control circuitry. The baby bottle warmer attachment is an additional feature that will allow the warming up of baby milk bottles This invention may be adapted for various other uses such as ashtray retrofit car beverage warmer and cup holder and an aircraft passenger seat beverage warmer.

Patent CA-2181707-A1 (CA)
Title: Isomerization catalyst and process
Inventor: COX WILLIAM L
IPC: C07B61/00
Filed: 1995-11-20
Abstract: A catalyst composition effective for isomerizing alpha-olefin to internal olefin and a process for conducting such isomerization using the catalyst composition are described. The catalyst comprises the combination of an alkyl aluminum alkoxide and a cobalt salt of an organic carboxylic acid or reduced form of such cobalt salt wherein the number of alkoxide groups in the alkyl aluminum alkoxide is sufficiently greater than 1 and sufficiently less than 3 per aluminum atom to provide an active catalyst for catalyzing such isomerization. Typically the alkyl aluminum alkoxide has the formula R3nA1(OR4)p where R3 and R4 are the same or different and are alkyl, n is an integer from 0.75 to 1.85, p is an integer from 1.15 to 2.25 and the sum of n and p is 3. The isomerization process using such catalysts proceeds rapidly and requires no addition of hydrogen to enhance the reaction. Failure to achieve the proper balance between alkoxide and alkyl groups on the alkyl aluminum alkoxide results in an inactive catalyst or a catalyst that is only minimally effective even at high temperatures.

IPC: D21F9/02
Filed: 1995-05-02
Abstract: The present invention refers to an under felt inclined flat former for making multilayer or monolayer sheets of paper. The forming unit is supported on corresponding rigid supports and is provided with a roll system on which the forming unit rests when the supports are removed, in such a manner that the selected forming unit can be removed from the production line for cleaning or maintenance purposes, without interrupting the operation of the former equipment. The paper sheet so formed has superior characteristics to that of a sheet made in a fourdrinier manufacturing table. Unlike prior art equipment, the present invention provides controls for fiber orientation. In addition, the present invention discloses a flow head box with a step diffuser. The step diffuser maintains the fibers in a state of complete dispersion. Thus, the advantages of using a step diffuser in combination with activity induction can eliminate streaks.   Further, the present invention provides for an adjustable tensile ratio. The tensile ratio can be controlled by adjusting the fiber orientation while maintaining even distribution of fiber.

Patent CA-2198949-A1 (CA)
Title: Fault Powered Fault Indicator Having Timed Reset
Inventor: SCHWEITZER EDMUND O JR
IPC: G01R31/58
Filed: 1997-03-03
Abstract: A fault indicator is described having a winding disposed on a magnetic pole assembly.  The winding delivers energy from a monitored conductor to circuitry of the fault indicator.  A series-connected threshold device, such as a four layer bilateral diode or a zener diode, precludes a capacitor from charging during normal current flow in the monitored conductor.  The series-connected threshold device, however, breaks down when a fault current flows in the monitored conductor.  After break down, the fault current charges the capacitor.  A shunt-connected threshold device, such as a zener diode, limits the voltage developed across the capacitor.  After its charging phase, the capacitor drives a multivibrator which actuates an LCD, displaying the occurrence of the fault current to an operator.  A series-connected threshold device shuts the LCD off when the voltage across the capacitor drops to a sufficiently low level.  The arrangement of these electrical components allows the operator to accurately define the duration of time in which the LCD displays the occurrence of the fault current in the monitored conductor.

Title: Cam-operated timer test procedure
Inventor: WEAVER ROBERT FRANCIS
IPC: H01H43/10
Filed: 1997-05-28
Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which turns a drive cam. The drive cam impartsmotion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.

Abstract: A primary stage optical switch assembly that is used in an optical fiber administration system where various levels of switching are used to interconnect an optical time domain reflectometer (OTDR) to individual optical fibers. The primary stage optical switch assembly contains an optical switch and a connector array disposed within a shelf structure. The shelf structure is sized to mount into one of the bays in the framework of the fiber administration system. The optical switch contained within the primary stage optical switch assembly is fabricated from electronic components and optical components. Most of the electronic components are manufactured as part of an electronic module. The optical components are manufactured as part of a separate optical module. Both modules mount within the shelf structure. However, the electronic module can be removed from the shelf structure without effecting the position of the optics module or the optical leads that extend from the optical module.
