Title: Tubular chemiluminescent lighting element
Inventor: LADYJENSKY JACQUES
IPC: F21K2/06
Filed: 1991-03-07
Abstract: TUBULAR CHEMILUMINESCENT LIGHTING ELEMENT                   ABSTRACT OF THE INVENTION     The invention reveals a chemiluminescent lighting element which consists of two concentric, long tubes each of which is made of a translucent and preferably flexible, synthetic material, one of which contains a first chemical liquid which emits chemiluminescent light, and the other of which contains a second chemical liquid whose function is to cause the light activation of the first liquid.  The internal tube is provided with as element which moves essentially along the entire length of said tube, by a pressure imparted to it through the wall of the external tube.  The sliding element is provided with a blade, which cuts the internal tube longitudinally as the element progresses along the tube and thus causes the liquid in each tube to mix whereby the first liquid is activated and chemiluminescent light is produced.

Title: Interlock queueing
Inventor: RAMANUJAN RAJ
IPC: G06F9/46
Filed: 1991-05-16
Abstract: ABSTRACT      A lockout avoidance circuit is provided for a plurality of nodes which generate lock requests for a shared resource such as a memory location.  The circuit insures that lock requests are eventually satisfied.  A lock queue includes a plurality of registers pipelined together.  Lock requests only enter the lock queue if they are refused access to a shared resource a predetermined number of times.  A first register is the head of the queue and the last register is the bottom of the queue.  An enabling circuit allows the queue to store in the registers lock requests received from the different nodes in the order in which they are initially refused service.  The enabling circuit operates the queue by pushing the stored lock requests toward the head of the queue each time the head entry in the queue is serviced.  The lockout avoidance circuit is implemented at each level of the system wherein a lockout condition can occur.

Title: Method and Composition for Improving the High Temperature Gel Stability of Borated Galactomannans
Inventor: DAWSON JEFFREY C
IPC: C08B37/00
Filed: 1992-04-08
Abstract: A complexor solution and method of use are shown for providing controlled delay and improved high temperature gel stability of borated fracturing fluids.   A base fluid is first prepared by blending together an aqueous fluid and a hydratable  polymer  which  is  capable  of  gelling  in  the presence of borate  ions.   The complexor  is prepared by mixing  a  cross-linking  additive   capable  of  furnishing borate ions in solution with a delay additive. The delay additive  is  effective,  within  a  selected  pH  range,  to chemically bond with both boric acid and the borate ions produced by the cross-linking additive to thereby limit the number of borate ions initially available in solution for subsequent cross-linking of the hydratable polysaccharide. In addition to providing more precise control of the delay time,  the  complexor provides  a  reserve  of  borate which provides improved gel stability at higher temperatures.

Title: Device and unit for coating cap-shaped substrates
Inventor: ETZKORN HEINZ-WERNER
IPC: C03C17/00
Filed: 1992-06-18
Abstract: To coat several cap-shaped substrates simultaneously in an economical way with the same and high quality, several coating chambers are connected into a cap coating station by a symmetrical gas line system with a common gas generator and by another gas line system with a common vacuum pump. The gas lines have a cross sectional area QA(x) and a cross sectional form QF(x) which as a function of the distance x from the gas generator or from the vacuum pump are substantially the same. In this way, the same flow conditions are assured in all coating chambers. The gas line systems can be formed by precision pipes or by a stack of solid plates, in which gas ducts are introduced by boring or milling. Several cap coating stations, which are connected by suitable symmetrical gas line systems with a common vacuum pump and a common gas generator, can be combined to form a unit.

Patent CA-2076227-A1 (CA)
Inventor: KASANDA PAUL J
IPC: B25F5/02
Filed: 1992-08-17
Abstract: Abstract A holding device designed specifically to hold screw driving bits for drills andother tools. As these driver bits are almost exclusively of a 1/4 inch diameter round or hexagonal shaft construction, this holder is designed to hold only these types of bits. The advantage of developing a holder that can accommodate only the most common driver bit format is that it allows the holder to be manufactured of a one-piece construction. This one piece construction provides the following combination of benefits never before available: - Assembly free mass production capabilities; - Use of one of five low cost manufacturing methods that can produce the product from rubber or plastic, in one step. These three methods are injection molding, compression molding die-stamping, extruding and laser cutting. - A multi-bit holding product which can be manufactured for under a dollar and retailed for under three dollars. This is an important feature for a successful after-market bit holding device, but especially important if the device is to besuccessful as a unit in which bit sets could be retailed in. While current drillindexes lack important features such as sturdiness and reliability their cost isonly in the order of a few cents.          Though not essential to the functioning of the BIT BAND, this patent identifies a new technology that will optimize the operation of this unit and ofany rubber unit designed to grip and release shafts and to provide temporary storage of said shafts. This technology is a specific profile of hole that optimizes grip properties on driver-bit shafts (or other types of shafts) while still allowing easy removal. The specific hole profile is "hour-glass" shaped and shall be referred to here after as Hour-Glass Profile (HGP). 9 Claims, 3 drawing sheets
