Title: Fluid level sensing systems
Inventor: RICHARDS PAUL NIGEL
IPC: G01F23/00
Filed: 1994-03-25
Granted: 2004-10-19
Abstract: A fluid level sensing system, particularly for sensing the water level in a steam generating boiler, comprises a vessel connected to the boiler so as to contain water and steam at substantially the same level as in the boiler, a number of vertically spaced electrodes projecting into the vessel, and circuitry for measuring the electrical impedance sensed by each electrode. The circuitry, which can be multiplexed to each electrode in turn, includes a first comparator for producing an output when the sensed impedance lies between the normal maximum impedance of the water and the normal minimum impedance of the steam above the water, this output being demultiplexed to drive a vertical display to show the level of the steam/water interface. The circuitry additionally includes a second comparator for producing a further output when the sensed impedance lies below the normal minimum impedance of the water, which further output is indicative of a variety of different fault conditions and drives a fault indicator.

Abstract: A tubular core assembly for winding or unwinding of sheet material, such as newsprint or Rotogravure Print, is provided wherein the opposed ends of an elongate cylindrical core are provided with inside diameter-reducing annular end members.  The inside diameter-reducing annular end members are mechanically interlocked with a central core body which is preferably formed by multiple wraps of a paperboard material.  Mechanical interlocking is accomplished by a plurality of axial grooves in the bodywall of the central core body member and a plurality of axially extending tongue members on the annular end members which are received in the grooves of the central core body member in interlocking relationship therewith. Because of the mechanical interlocking relationship between the inside diameter-reducing annular end members and the central core body member, the inside diameter-reducing annular end members are secured to the central core body member in positive circumferential and axial locking relationship.

Abstract: A data write apparatus includes a card conveyor path, a recording head, a sensor circuit, a CPU, a drive circuit, and an enable section.  A magnetic card is conveyed in the card conveyor path.  The recording head is arranged on the card conveyor path and performs a recording operation on the magnetic card by energizing a winding coil.  The sensor circuit is arranged on the card conveyor path near the recording head and detects the magnetic card conveyed in the card convey path to output a detection signal.  The CPU outputs write data to be written on the magnetic card in response to the detection signal from the sensor circuit.  The drive circuit energizes the winding coil of the recording head on the basis of the write data from the CPU to perform the recording operation.  The enable section enables the drive circuit for a predetermined time after the write data is output from the CPU to limit energization for the winding coil of the magnetic head to a time equal to or shorter than the predetermined time.

Abstract: An oxygen respirator with safety and simple handling, comprising a body, a small portable-type oxygen cylinder or oxygen generator mounted on the body, a mask, a first hose transferring oxygen from the body to the mask, a tank member mounted on the body for receiving exhalation, a second hose transferring exhalation from the mask to the body, and a carbon dioxide absorbing material charged in the body for removing carbon dioxide from exhalation sent back from the mask to the body. During emergency and evacuation for example in fire, thus, oxygen is transferred to the mask by removing a trigger or the like. The respirator also enables the reuse of exhalation for respiration.      Despite of the small size, therefore, the respirator can protect a user from risks such as suffocation for a relatively long period of time.

Title: Container and lid for container
Inventor: JAMISON BARRY
IPC: B65D25/00
Filed: 1995-09-29
Granted: 2000-12-05
Abstract: A container has a drop gate and lids that open along hinge joints formed at the upper end of the side walls.  The drop gate is formed in one end wall and the lids can also be opened half way from the end wall in which the drop gate is formed.  In this way, access to the interior of  the container can be gained through the open drop gate and the open half of the lids so that the container can be used as a shelf box or hopper in a flow racking system.  Further, when the lids are opened along their respective side wall hinge joints, the container can be used as a distribution tote.  When the container is also used as a bulk shipper by vendors or suppliers, the container can perform three functions in a distribution system.  Specifically, the container can be first used as a bulk shipper, then, without unpacking the goods, the container can be shelved on a flow racking system from which orders can be selected at a distribution center. Finally, the container can be used again for shipping the goods from the distribution center to retail outlets and returned to either the distribution center or suppliers in a nested stack.

Abstract: La présente invention concerne un procédé de production d'un bâtonnet antitranspiration solide, comprenant un sel antitranspiration d'aluminium particulaire, en suspension dans un excipient anhydre. Cet excipient comprend un composant à point de fusion élevé qui fond à 70  DEG C ou plus. Ce procédé consiste à chauffer l'excipient dans une cuve de mélange fermée, à une température dépassant 70  DEG C, de préférence dépassant 75  DEG C, afin de faire fondre le composant à point de fusion élevé, à ajouter le sel antitranspiration à l'excipient, et à refroidir l'excipient afin d'obtenir un bâtonnet antitranspiration solide. L'amélioration de la présente invention consiste à refroidir l'excipient en dessous de 70  DEG C, de préférence à environ 65  DEG C ou moins, mais au-dessus du point de solidification avant d'ajouter le sel antitranspiration, et de maintenir l'excipient au-dessous de 70  DEG C, de préférence à environ 65  DEG C ou moins, pendant et après l'ajout du sel antitranspiration, ce qui empêche ainsi le sel antitranspiration de s'agglomérer en grosses particules, notamment en particules de plus de 60 microns.
