Abstract: A sensor arrangement for measuring the temperature of molten masses uses a receptacle having at least one strip-shaped or wire-shaped carrier and an opening on its upper side, with a thermoelement placed inside the receptacle. In order to make available a sensor arrangement for the exact determination of the liquidus temperature of molten cryolite, the receptacle is made of metal. A temperature measuring device with a sensor arrangement of this type, has at least one carrier mounted at its end facing away from the receptacle in a sleeve, the sleeve being detachably connected to a mounting device. In addition, a process for measuring the liquidus temperature of molten cryolite in a receptacle vibrates the receptacle during the cooling of the molten cryolite.

Inventor: FINCH DAVID P
IPC: A61N1/39
Filed: 1996-01-10
Granted: 2000-12-05
Abstract: A  defibrillator,  such  as  an  atrial  defibrillator, applies cardioverting electrical energy to the atria of a heart when the atria are in need of cardioversion.  The atrial defibrillator includes an atrial sense channel for sensing atrial activity and ventricular sense channels for sensing ventricular activity to generate heart activity data, a memory for storing the heart activity data, and a cardiovertor which applies cardioverting electrical energy to the atria if the heart activity satisfies a predetermined criteria.

Abstract: A guard guide surface for the lift-off slot of a tilt sash shoe is disposed obliquely above the lift-off slot to engage the head of a sash pin rising directly vertically from the slot. This prevents accidental withdrawal of a sash pin from a shoe when the sash is tilted. When the sash is slanted, however, for intentional withdrawal from a window, the sash pins can be lifted from their slots in off-vertical motions that clear the guide surface.

Title: Tilt detector for roll-up door
Inventor: BLAIR WILLIAM J
IPC: G08B13/08
Filed: 1996-03-29
Granted: 2001-10-23
Abstract: The device is based on a tilt-sensing switch of the mercury-bridges-gap type. The device measures the tilt angle of the bottom slat of a roll-down door. If the slat becomes tilted, due for example to one end of the slat becoming snagged in the guideway at the side of the door, the sensor detects the tilt, and arrests the downwards movement of the door, before the slats can spill out and escape from the guideway.

Granted: 2000-01-11
Abstract: Horizontal, small diameter cyclones are disclosed. Gas and fines are introduced via an inlet (310) tangentially around a clean vapor outlet tube (314) in a cylindrical cyclone (300). A vortex of solids and some gas pass into a contiguous and axially aligned cylindrical vortex containment body (410) from which solids are withdrawn via a horizontal slot (460). Removal of particles <5micrometers is enhanced. An FCC process uses the cyclones as a third stage separator. An alternative design uses a half pipe extension (430) on the solids' outlet to confine the vortex of solids and gas.

Title: Extracts of shark cartilage having an anti-angiogenic activity and an effect on tumor regression; process of making thereof
Inventor: DUPONT ERIC
IPC: A61K35/32
Filed: 1995-04-21
Granted: 2001-01-16
Abstract: The present invention relates to shark cartilage extracts and to a method of producing the same, these extracts having anti-angoigenic properties (reduction of the area of blood vessels observed in vivo on experimentally induced tumors), tumor regressive activity in vivo as well as demonstrating a direct inhibitory effect on tumor cell lines. This process does not involve any denaturing solvent or product and does not involve the use of any enzymes. It consists of obtaining a blend of whole cartilage in an aqueous solution of neutral pH, preferably pure water, this blend being centrifuged and the pellet and supernatant kept for further processing. The pellet is iyophilized and tested for anti-tumor and anti-angiogenic activities in vivo and in vivo, with or without supernatant. The supernatant has been shown to have anti-angiogenic and tumor regressive activities in vivo. the composition of the supernatant has then been investigated by different ways. Fractionation of thissupernatant led to the characterization of some of its active components,The fractions were tested for their direct in vitro activity on cancer cell lines. Therefore, it is assumed that the non-fractionated supernatant has such an in vitro activity. Lyophilization substantially destroys the activity of these liquid fractions while no such abolition is observed in the solid extract.

Filed: 1995-10-03
Granted: 2005-12-27
Abstract: The invention relates to a method and apparatus for guiding a thin web material (I) while folding the web material (1) over a triangular former (4). The apparatus includes two guide rolls (2, 3) over which the web material (I) is driven. The second guide roll (3) is secured to a baseline (5) of the triangular former (4).

Title: Apparatus for cleaning a hydraulic fluid
Inventor: BECHER MANFRED
IPC: B01D21/26
Filed: 1997-07-14
Granted: 2006-07-11
Abstract: An apparatus for leaning hydraulic fluid includes a centrifugal fluid-spinning disk arranged in a housing, of which an upper portion forms a vapor chamber and a lower portion forms a fluid collecting basin. A vacuum pump is connected to the housing through an oil mist separator, such that water vapor is vacuumed away and hydraulic fluid collects in the oil mist separator to then be pumped away. The apparatus further includes preferably a single container that contains both the contaminated hydraulic fluid that is to be cleaned and the cleaned hydraulic fluid. A flexible inlet line and a flexible outlet line with respective hydraulic quick connectors are provided to connect the apparatus and particularly the oil container to a hydraulic system of an aircraft, for example. A high pressure pump connected to the outlet line pumps the cleaned hydraulic fluid into the aircraft hydraulic system and a pressure maintaining valve in the inlet line maintains the system pressure. The apparatus is embodied as a self-contained and self-sufficient mobile unit mounted on wheels. With this apparatus, the hydraulic fluid in the hydraulic system of an aircraft can be cleaned directly plane-side, and it is unnecessary to provide an exchange quantity of hydraulic fluid.

Title: Procedure and device for processing signals representing waves reflected or transmitted by a volumic structure with a view to exploring and analysing the structure
Inventor: DORY JACQUES
IPC: G01S7/523
Filed: 1997-07-15
Granted: 2009-02-10
Abstract: The procedure enables processing signals representing the waves reflected or transmitted by an object (O) in order to carry out an analysis of the structure of the object. The process includes transmission of waves incident on the structure and reception of the waves reflected by the object using a number of detection elements (D1 - Dn) independent of one another. After reception and digitisation the information is stored in a field memory (MC). For each point of the object (Pij) a calculation is carried out for the positions occupied in the field memory for the signals detected by each of the detection elements at a given instant. This position information is then applied to a further process which allows the determination of the size and form of the reflected wave, in order to determine the structure of the object (O).

Title: Seat and seat belt sequence circuit
Inventor: SHOEMAKER JIM MILTON
IPC: B60R22/48
Filed: 1998-05-05
Granted: 2002-04-23
Abstract: A simple discrete component logic circuit with transistors selectively connectedthrough seat and belt switches to the battery. The transistors operate in either an off mode or a current saturation mode. The circuit includes a plurality of identical resistors and transistors for ease of assembly and reduced cost and can operate over a wide range of voltages without need for power regulation or filters. The circuit recognizes the proper logic sequence with the key switch in either the on or off position but an improper sequence warning signal is provided only after the key switch is turned on. The circuit prevents intermittent warnings or interruptions caused by the operator temporarily bouncing from the seat, but the proper sequence of operations must be preformed and the switches must be operational to prevent a warning signal.
