Title: Vessel Position Locating Device
Inventor: NASH JOHN
IPC: A61B17/12
Filed: 1993-09-30
Abstract: A device for determining the location of the wall of an artery in a living being via a percutaeous incision or puncture. The device comprises an elongated tubular member having a distal end portion, a proximal end portion, and a passageway extending therethrough for receipt of a guide wire. The device is inserted through an introducer sheath having an open distal end into said percutaneous incision or puncture over said guide wire so its distal end portion is located within the artery and its proximal end portion is located outside of the body of the being. The has two liquid entrance ports in its distal end portion and one liquid outlet port in its proximal end portion. The liquid entrance ports and outlet port are in communication with each other through the device's passageway. When the device is positioned within the introducer sheath and the entrance ports are located beyond the open distal end of the introducer sheath and within the artery blood flows into the entrance ports through passageway and out through the outlet port so that it can be observed. The device and introducer sheath are then retracted until the flow of blood out of the outlet port stops, thereby indicating the location of the artery wall.

IPC: H04R3/00
Filed: 1995-05-18
Abstract: The long term average broad band gains of a plurality of individual signal channels, associated with a corresponding plurality of microphone elements, are electronically and dynamically adapted to one another. This is realized by periodically and dynamically processing the signals from the individual microphone elements. More specifically, the processing is such that the long term average broad band gain of the signal channels of the individual microphone elements is dynamically adjusted, an energy estimate of each microphone signal channel is averaged over the long term and the difference in energy between the signal channels is used to readjust the long term average broad band gain of the microphone signal channels to minimize those differences. In one embodiment the adjustment is realized by obtaining an estimate of the energy of the adjusted signal in each microphone signal channel, obtaining the differences between the energy estimates and averaging the difference over the long term to obtain a gain differential correction factor which is used to readjust the long term broad band gain of at least one of the microphone signal channels to minimize the gain difference between the microphone signal channels. In another embodiment, a long term estimate of the energy in each microphone signal channel is obtained. A ratio of the energy estimates is obtained and used to adjust the long term average broad band gain of at least one of the microphone signal channels to equalize the gain in the microphone signal channels.

Title: Cementitious materials and method of making the same
Inventor: BABAEV SHAHVIRAN TEIMUROGLY
IPC: C04B24/30
Filed: 1995-10-16
Abstract: The cementitious material comprises an initial mixture of portland cement clinker and a modifier ranging in weight from approximately 0.5% to 5%, preferably 1%, of the weight of the clinker. The modifier is selected from a group comprising (a) a melamine formaldehyde - sodium bisulfite copolymer, and (b) sodium naphthalene sulfonate.  The portland cement clinker and the modifier are intimately mixed and caused to react together in a solid state reaction by energetically grinding them together in a highly energetic ball-and-tube grinding mill to a high degree of fineness of at least approximately 5000 Bleine.  Modified cementitious materials are produced by providing an additional constituent in the initial mixture comprising a hard, dense, substantially inert mineral material ranging up to 70% of the mixture by weight. The percentages of the portland cement clinker and the modifier are correspondingly reduced. The modified initial mixture is ground as before.  The cementitious materials are substituted for traditional portland cement in making concrete having increased strength, density, durability and impermeability, while having decreased water demand, porosity and capillarity. The mineral material is selected from a group comprising sand, comminuted stone, comminuted scrap material from glass making, comminuted waste material from ore enrichment plants, comminuted volcanic material, comminuted slag, fly ash, comminuted pumice, and comminuted perlites.

IPC: A41D13/08
Filed: 1996-07-04
Abstract: The wrist guard can be secured to the hand and wrist by a single strap, to provide protection to the hand and wrist. A rigid palm pad, removably attached to the guard over the palm, protects against impact and abrasion. A relatively stiff or substantially rigid support member is removably attached to the guard on the back of the hand and wrist to prevent backward flexion of the hand while permitting forward flexion. The hand and back of the wrist remain exposed for breathability. A flexible strap across the back of the forearm cushions the arm from the support during a fall. The support member includes a flexible rim across the top, across the back of the hand, to cushion the hand from the support during a fall. The guard is modular in nature such that the guard can be used without the support member when less protection is required or when less bulk and weight is desired. The palm pad and support member can be removed to facilitate cleaning of the guard. The guard can be worn with a wrist watch with the watch face visible to the user.
