Title: Door liner and door assembly for a coke oven
Inventor: SUEY PAUL V
IPC: C10B25/06
Filed: 1987-11-20
Granted: 1992-10-13
Abstract: Abstract A coke oven door liner comprises a first refractory layer,  a  second  refractory  layer  and  connecting means.  The first refractory layer has an outer surface which is adapted to abut the inner surface of the coke oven door and has width and height  dimensions  which  are  substantially  coextensive  with those of the opening to the coke oven which is sealed by the coke oven door.  The second refractory layer, disposed within the coke oven, has width and height dimensions substantially coextensive with  those of  the  first  refractory layer  and is spaced  apart  from  and  generally  parallel  to  the  first refractory layer,  thus  creating an  elongated chamber  between the  first  and  second  refractory  layers.  A  connecting  means connects the second refractory layer  to the first refractory layer and allows for gases created by burning coal within the coke oven to enter the elongated chamber created between the first and second refractory layers and rise to the top portion of the coke oven to be removed from the coke oven.         A coke oven door assembly comprises a door  and the coke oven door liner.

Title: Diamond compacts
Inventor: RINGWOOD ALFRED E
IPC: B23B27/14
Filed: 1988-03-21
Granted: 1993-09-07
Abstract: ABSTRACT        A process for producing a diamond compact comprised of diamond crystals bonded mainly by silicon carbide.  The diamond crystals are intimately mixed with silicon in the proportions 97 to 65 percent by weight of diamond to 3 to 35 percent by weight of silicon.  The thus mixed diamond crystals and silicon (1) are placed immediately adjacent to one or more bodies of silicon (3) within a container (2) and subjected to high pressure and temperature so an to cause melting of the pre-mixed silicon and of the external silicon which infiltrates into the interstitial spaces between the diamond crystals to cause most of the silicon between the diamond crystals to react with diamond to produce silicon carbide.  The elevated temperature is in the range 1100 to 1800°C and the elevated pressure is in the range 10 to 40 kilobars.  The resulting compact contains between 50 and 85 volume percent of diamond with a density of at least 3.35 g/cm3 and a compressive strength of at least 10 kilobars.

Title: Compound rotary internal combustion engine
Inventor: STAUFFER JOHN E
IPC: F01C1/073
Filed: 1988-04-11
Granted: 1994-02-08
Abstract: ABSTRACT     An internal combustion engine of the rotary type in which a pair of axially spaced combustion chambers are provided and a common ratchet or control mechanism is positioned between the spaced combustion chambers.   A pair of vanes  are  mounted  in  each combustion chamber with the vanes mounted on concentric shafts and free to rotate relative to each other.   The ratchet mechanism positioned between the combustion chambers functions to resist counterclockwise movement of the vanes in one combustion chamber while allowing free clockwise movement thereof.   The reaction forces generated in the  ratchet  mechanism  from the  two combustion chambers thus tend to cancel each other out. The central ratchet mechanism includes a housing which absorbs  the reaction forces  from both  combustion chambers and which is free to rotate in the event that the reaction forces generated in the two combustion chambers become unbalanced.

Title: Compact packaging of electronic equipment within a small profile enclosure
Inventor: HENNEBERG HELMUT H
IPC: G06F1/18
Filed: 1988-04-22
Granted: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE      The  electronic  equipment of  a  computer  system including electronic cards,  power supplies,  peripheral units,  cooling units and internal and external cables are compactly packaged within a small  enclosure in a way which permits sufficient airflow from front to rear of  the enclosure.   The  enclosure includes a pair  of rail members located at the rear which have a plurality of  mounting  positions  for  attaching  a  corresponding number  of modular  shelf members which are angled to permit  the  flow  of  air  through  established  airflow paths.   The rail and shelf members collectively form a bulkhead structure.   The rail members are offset from the sides of the frame so as to form vertical channels on each  side.   The  channels  are  used  for  retaining external  cables which plug into connectors mounted on the  shelf members  and  are  distributed so  as  not  to interfere with airflow.

Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE A high efficiency envelope amplifier  (20)  is disclosed,  The invention includes a power supply (24), a comparator (60), and several switches (26-38).  The power supply (24) is capable of providing multiple outputs. The comparator (60) measures the amplitude of an input signal against one of several threshold levels.  When the input signal is within a predetermined range, a selected power supply output is switched onto the output path. Since the present invention incrementally switches small amounts of power, switching losses are substantially mitigated.

Title: Baler
Inventor: VAN DEN WILDENBERG LEONARDUS J
IPC: A01F15/07
Filed: 1988-08-11
Granted: 1993-02-09
Abstract: ABSTRACT BALER A baler 1 comprises a forming mould 3 into which the material 4 to be compressed is brought. The strip of material 4 moves through the opening 5, arrives in the forming mould and, with the aid of driving means, is compressed to a bale. Netting material 9 which is placed on a supply roll 8 is fed with the aid of transport rolls 10, 11 to the forming mould 3 and there wound around the bale. The breadth of the netting material transverse to the feeding direction is according to the invention greater than that of the forming mould 3. Through use of the invention the edge zones of the net are turned over the end faces of the bale and, owing to the elasticity, the net draws itself firmly around the formed bale.

Abstract: ABSTRACT OF THE DISCLOSURE           A water backflow preventing system is provided for a given area having a sewer line for receiving rain and other water where the sewer line is incapable of carrying, without backup, a given flow rate of water.  The sewer line (4A or 4B) is provided at a given point (D) therealong with at least one overflow opening (sewer opening into which standpipe 35 extends) into which opening water which cannot be handled by the sewer line will rise and overflow.  Water storage tank means (22 or 24) are buried in the ground below the sewer line and into which the overflow water from said opening will drain and be temporarily stored.  The storage tank means (22 or 24) have a volume to store many thousands of gallons of water which cannot otherwise flow in the sewer line. A pump (36)is placed in the bottom of the storage tank means.  Various float switches (FS', FS) are placed in different parts of the system for controlling the pump.  They are arranged to prevent the operation of the pump when water backup valve conditions exist in the sewer line and to automatically render the pump means operative when backflow conditions disappear from the sewer line so that the storage tank means can be substantially emptied and accommodate overflow conditions which can be caused by a subsequent rainstorm.
