Title: Semimetal-semiconductor heterostructures and multilayers
Inventor: GOLDING TERRY D
IPC: H01L21/285
Filed: 1993-07-19
Abstract: The present invention provides for the fabrication of single layer semimetal/semiconductor heterostructures and multilayer semimetal/semiconductor structures. Each semimetal/semiconductor layer fabricated in accordance with the present invention has compatible crystal symmetry across the heterojunction between a semimetal and a semiconductor. A single layer semimetal/semiconductor structure is fabricated by growing a rhombohedral semimetal in a [111]  direction on a substrate material having a (111) orientation, and then growing a zincblende semiconductor in a [111] direction on the semimetal. A multilayer semimetal/semiconductor structure may be grown from the single layer semimetal/semiconductor structure by growing an additional rhombohedral semimetal layer in a [111]  direction on the preceding semiconductor grown, then growing an additional zincblende semiconductor layer in a [111] direction on the additional semimetal layer, and then repeating this process as many times as desired. Each semimetal to be sandwiched between semiconductors in the multilayer semimetal/semiconductor structure may be grown thin enough that the semimetal is converted into a semiconductor.

Title: Treatment for improving cellulosic insulation
Inventor: ROOD LEONARD D
IPC: D21H21/34
Filed: 1995-06-02
Abstract: A  method  for  manufacturing  fire  retardant cellulose  fibers.    The  method  comprises  mixing limestone with shredded cellulosic fibers, mixing an acidic agent with the fibers, and depositing water on the mixture of  fibers,  limestone  and acidic agent.    A  chemical  reaction  results  from  the limestone and the acidic agent being combined in a sufficiently  moist  environment.    The  reaction liberates  carbon  dioxide  gas  which  causes  a mechanical foaming action, thereby breaking down and distributing the produced particles of the chemical reaction.   The preferred acidic agent is ammonium sulfate  combined  with  boric  acid.    The  method preferably includes  the application of  an anti-static agent in the step that includes mixing the limestone with the fibers.   The water deposited preferably comprises an amount substantially in a range from 6%-16% of the weight of the fibers.

Title: Forming casing window off whipstock set in cement plug
Inventor: DOREMUS DENIS
IPC: E21B7/06
Filed: 1995-06-26
Abstract: Methods and systems for forming a window through the wall of a well casing to enable a new borehole to be drilled outside the casing include forming a cement plug in the cas-ing, drilling a laterally offset hole in the cement plug, orienting and setting a whipstock in the offset hole, and using the whipstock to drill an elongated window through the casing wall opposite its deflector surface.

Title: Circuit breaker
Inventor: OVICK NORMAN LESTER
IPC: H01H73/36
Filed: 1995-07-12
Abstract: A  circuit  breaker  having  electrical  contacts operable between a closed position in which a circuit is completed through the conductor and an open position in which the circuit through the conductor is interrupted.  The circuit breaker includes a latchable operating mechanism operable to open the electrical contacts when unlatched and a trip bar rotatable from a biased position to a trip position to unlatch the operating mechanism.   A magnetic trip assembly is provided including a frame, a stationary magnetic  structure mounted to  the  frame  and a movable armature which  is  attracted to the  stationary magnetic structure by abnormal  current through the conductor to rotate the trip bar to a trip position.   The movable armature includes a nib extending angularly therefrom, the nib defining a detent.  The armature is pivotably mounted to the stationary magnetic frame by a pin.   A spring biased plunger supported by the frame engages into the detent to bias  the  armature  away  from  the  stationary  magnetic structure  to  form  a  gap  therebetween.    The  plunger disengages from the detent when the armature is attracted to the stationary magnetic structure by the abnormal current through the conductor to allow the movable armature to rotate about the pin and trip the trip bar to interrupt the circuit.

Title: Smart cooler
Inventor: SZEREDI DEZSO
IPC: A47J41/00
Filed: 1995-12-04
Abstract: The present invention is an improved beverage cooler which has the added benefit of functioning as a regular multi-purpose cooler. This cooler has many advantages over present coolers on the market. First, you are able to dispense carbonated and non-carbonated beverages from outside the cooler without opening up the cooler. Second, the cooler provides a much more efficient use of the consumers time by putting the beverages within easy access of all the users. Third, the cooler maintains the beverages at their intended temperature for longer periods of time since the cooler is not opened up when dispensing the beverages. The cooler is fabricated from a plastic material which is highly resistant to the environmental conditions to which it will be exposed, it is very economical to manufacture. In essence, the device consists of two parts and the lid which when joined together fonn the cooler assembly. The top portion of the cooler is where the improved beverage dispenser mechanism is located. In this section one or more openings in the side wall of the top cooler allow for the protuded instalation of vented valves to which various beverage containers can be attached. The beverage containers are supported inside the device by molded, or removable and adjustable partitions. The purpose of the supports is to allow gravity to feed the dispensing system of the device. One of the advantage of adjustable partitions is that they can support a wide variety of beverage containers. In addition to the above, the top portion of the container contains a separate space for storing other items. This area is accessed through a access door integrated lid design, which allows the beverage area to maintain its insulating efficiency. The bottom portion of the cooler has a unique set of hinged handles which serve two purposes. First, they join and lock both parts of the cooler and at the same time act as a handle for transportation of the device when locked to the upper portion of the cooler. Second, it has the added benefit of covering the valves during transport to prevent damage.
