Title: Method and apparatus for filling powder
Inventor: TAKEMOTO SHIGEHIDE
IPC: B30B15/30
Filed: 1997-03-20
Granted: 2000-11-07
Abstract: A method and apparatus for filling a cavity with powder wherein a pipe having holes for discharging gas is disposed in a powder box and gas is discharged into the powder in the powder box as the powder enters the cavity so that particles of the powder are movable relative to each other. Due to the gas discharge, the powder can enter the cavity smoothly without whirling up in the cavity and settling unevenly, so that a filling time period is shortened and a particle size distribution in the cavity is uniform.

Abstract: A pivoted hand tool, such as a scissors, includes a pair of blades having non-rectilinear cutting edges to form various cutting patterns on a sheet of paper.  The scissors also include at least one guide to control the angular presentation of the paper to the blades and limit the amount of paper presented to the blades.  The guide may also include a pair of ridges spaced apart from a pair of abutting surfaces, thereby providing a way to further limit the amount of paper presented to the blades.  The scissors preferably have identically-shaped handles and oppositely facing guides to enable a user to create several complementary patterns on the sheet of paper simply by reversing the position in which the scissors are held.

Abstract: A method and apparatus for detecting the degree of deterioration of a lubricating oil for an operating machine includes a grid-like capacitive sensor (20) that uses the lubricating oil as a dielectric medium. A magnetic field is imposed upon the oil to attract ferromagnetic wear particles into the vicinity of the sensor. Preferably, the magnetic field is generated by at least two independently controlled electromagnet windings (26, 28) aligned such that the magnetic field produced by each winding acts upon the wear particles. A plurality of capacitance measurements are taken at periodic intervals at each of several magnet operational states for respective classification and analysis. All windings may be simultaneously de-energized for release of captured particles back in to an oil circulation stream and to clean the capacitative sensor grid of accumulated particulates.

Abstract: An overcenter mechanism (10) includes a housing (12) and a first shaft (14) mounted on the housing. The first shaft has a first axis (34). A second shaft (20) is mounted on the housing and the second shaft has a second axis (41) that parallels the first axis. A lever (16) is attached to the first shaft, and the lever pivots about the first axis in response to a force (F op) applied to the lever. A cam (18) is attached to the first shaft, and the cam pivots about the first axis. The cam has a cam surface including a first surface portion (58) and a second surface portion (60). The first and second surface portions form a cusp (62) therebetween. A cam follower (21) has a cam follower surface, and the cam follower pivots about the second axis. A  biasing member (26) urges the cam follower surface against the cam surface in pressure contact. The cam follower and the pressure contact cooperate with the cam to generate torque (~holler) on the cam until the cam follower surface contacts the cusp. The pressure contact creates an instability about the cusp when the cusp contacts the cam follower surface, and the torque pivots the cam so the cusp and the cam follower move away from each other.

Abstract: L'invention porte sur un appareil et une méthode de partage d'une voie de communication entre deux ou plusieurs stations de base raccordées au contrôleur d'une station de base par une ligne de transmission commune découpée en canaux. L'invention permet à chaque station de base de recevoir des données transmises par le contrôleur de la station de base au moyen d'un canal de communication partagé, de déterminer si les données transmises par le contrôleur sont bel et bien destinées à cette station de base et d'introduire ses données dans le canal de communication sans brouiller les données transmises par les autres stations de base qui utilisent le même canal de communication. Dans une version, chaque station de base est configurée de façon à être raccordée à l'installation de transmission afin que les messages transmis par un canal de signalisation puissent être reçus par toutes les stations de base. Les messages de signalisation ont des identificateurs associés qui précisent les stations de base particulières auxquelles le message est destiné. Dans une autre version, chaque station de base peut introduire dans le canal de signalisation son message de signalisation dans le train de données sans brouiller les messages de signalisation se trouvant déjà dans ce train de données.

Abstract: To make coincide cutting centers of two end surfaces of raw wood with the axis of spindles of a veneer lathe, at least two axial corrections which are performed in a state in which the raw wood is held by centering spindles are required. Conventional apparatuses suffer from too complicated structures and enlargement of the cost because of the complicated structures. A correction operation of an axial direction of correction operations in the two axial directions is performed such that only a movable centering spindle is moved in a direction intersecting a direction in which holding arms are extended/contracted. Another correction operation in another axial direction is performed by extending/contracting the holding arms.

Abstract: The invention refers to methods for assessing absorbent structures (10) for their fluid handling ability by using materials (110) having a moisture pick up ability which is very close to the one of human skin. This is achieved by using materials (110) which do not function based on capillary transport for moisture, but which comprise as an essential element swellable but non-soluble materials in a film form. Such materials (110) can be based on proteins, Glycin, Prolin, 4- hydroxyprolin, naturally occurring sugars, glycerin, sorbit and collagen. A particularly preferred material is a film material comprising collagen. To simulate a baby's weight upon the absorbent structure (10), a load (16) may be utilized therewith.
