Title: Vibrating screen with arched frame and ballast
Inventor: MACNAUGHTON DOUGLAS J
IPC: B07B1/00
Filed: 1996-09-03
Granted: 1999-08-24
Abstract: A portable vibrating screen comprising an arched frame, a basket supported on top of the arched frame by springs and a rotatable eccentric shaft for impartinga reciprocal movement to the basket. The arched frame has a vertical tall end, a vertical short end and two spaced apart stringer members joining the upper portions of the tall and short ends. The stringer members define an inclined plane between the tall end and the short end. The tall end has a first pair of spaced apart leg members and a first ballast mounted between the leg members of that first pair. The short end has a second pair of leg members and a second ballast mounted between the leg members of that second pair. An amplitude of a vibration of the basket transmitted to the arched frame is largely absorbedby the mass of the first and second ballasts. In another aspect of the present invention, the eccentric shaft has bearings attached to the basket and to the stringer members for retaining the basket along the inclined plane. The stringer members are flexible, within an elastic limit thereof, a sag distance corresponding to at least an offset dimension of the offset shaft. When the basket is filled with a load of screenable material which is larger than a normal load, the eccentric movement of the shaft is partly or entirely absorbed by the deflection of the stringer members.

Abstract: The economic production of raised printed characters such as Braille is achieved by a "screen printing" process, using a rotational printing machine in combination with high viscosity, "U/V" inks that make possible the depth of deposition and character solidity necessary for achieving the required tactile effect in order to be "readable" by touch.      The high body ink of the thus formed characters is cured comparatively rapidly by exposure to U/V light, so that the high drying rate thus obtained enables the achievement of economically effective rates of production. It is found that raised patterns of significantly lesser prominence than for embossed Braille, as produced by the printing process, are readable on a short-term basis, even by trainee "readers".

Abstract: Une station de base d'un réseau de communication à accès multiple par répartition de code (AMRC) (conforme à la norme IS-95 p. ex.) est sectorisée de façon que la transmission du contenu d'un premier sous-ensemble de canaux AMRC utilise une sectorisation d'emplacement de cellule de premier niveau et que la transmission d'un deuxième sous-ensemble de canaux, différent du premier, utilise une sectorisation d'emplacement de cellule de deuxième niveau, différent du premier niveau. Par exemple, le premier sous-ensemble de canaux AMRC peut regrouper les canaux d'onde pilote et de synchronisation, et le deuxième les canaux d'accès, de téléappel et de trafic. Dans un groupe de réalisations, au premier niveau de sectorisation, chaque emplacement de cellule est omnidirectionnel (pour le premier sous-ensemble de canaux AMRC), tandis qu'au deuxième niveau de sectorisation, chaque emplacement de cellule est divisé en deux ou plusieurs secteurs (pour le deuxième sous-ensemble de canaux AMRC). Dans ce groupe de réalisations, un décalage de pseudobruit (PN) est affecté à chaque emplacement de cellule et chaque emplacement de cellule transmet le contenu d'un canal d'onde pilote. Dans un autre groupe de réalisations, au premier niveau de sectorisation, chaque emplacement de cellule est divisé en deux ou plusieurs secteurs (pour le premier sous-ensemble de canaux AMRC) tandis qu'au deuxième niveau de sectorisation, chaque secteur redivisé en deux ou plusieurs secteurs (pour le deuxième sous-ensemble de canaux AMRC). Dans ce groupe de réalisations, un décalage de pseudobruit (PN) est affecté à chaque secteur et chaque emplacement de cellule transmet le contenu d'un canal d'onde pilote différent pour chaque secteur. Dans les deux cas, la présente invention permet d'offrir certains avantages de la sectorisation (p. ex., capacité accrue et brouillage réduit) tout en réduisant certains de ses inconvénients (p. ex., brouillage de canal pilote, traitement des transferts). En outre, elle peut être appliquée au soutien de stations à distance (p. ex., téléphones mobiles/cellulaires) munies de récepteurs RAKE à trois éléments (fingers).

Abstract: A method of logging a tree includes the steps of cutting the tree part way through the trunk near the bottom with two cuts lying in generally the same plane to leave a connecting portion (holding wood) between the resulting two generally parallel cut edges, and driving support wedges or the like into both said cuts to stabilize the tree trunk. A helicopter above the tree is connected to a point near the top of the trunk. The helicopter is moved away from the tree, thereby breaking the connecting portion (holding wood) and allowing the upper portion of the tree to be carried away by the helicopter. The method utilizes a grapple connected to the helicopter by two cables, one connected to the helicopter below the pilot's seating position and another bellow the center of gravity.

Granted: 2001-06-05
Abstract: An input device for a Programmable Logic Controller is taught. Briefly state d, an incoming input voltage is rectified with an input impedance being principally capacitive in order to avoid heat dissipation. This rectified power in turn cooperates with a current source such that once a set point is reached the current source current does not increas e with increasing input voltage. The current source is also utilized to prevent off-state leakage current from turning on an input optocoupler by  allowing most of the input current to be drawn through the current source until a turn-on threshold which is set by a zener diode is me t.

Title: Apparatus and method for visualizing ultrasonic images
Inventor: DEKEL DORON
IPC: G01S15/89
Filed: 1997-11-28
Granted: 2007-05-15
Abstract: The present invention provides a system and method for visualizing internal images of an anatomical body. Internal images of the body are acquired by an ultrasound imaging transducer. The position and orientation of the ultrasound imaging transducer is tracked in a frame of reference by a spatial determinator. The position of the images in the frame of reference is determined by calibrating the ultrasound imaging transducer to produce a vector position of the images with respect t o a fixed point on the transducer. This vector position can then be added to the position and orientation of the fixed point of the transduce r in the frame of reference determined by the spatial determinator. The position and orientation of a medical instrument used on the patient are also tracked in the frame of reference by spatial determinators. The position and orientation of the instrument is mapped onto the position a nd orientation of the images. This information is used to generate processed images from the images acquired by the transducer. The processed images are generated from a view spatially related to the position of the instrument. The system is expandable so that more tha n one instrument and more than one transducer can be used.

Granted: 2007-07-03
Abstract: An existing box-making machine is retrofitted by first removing the pull rolls and impression cylinder and other associated parts and cross-ties. However, the heavy duty side frames and drums, including the print cylinder are left intact in the box-making machine. A vacuum transfer machine is then inserted in the box--making machine and mounted to the existing frame to replace the pull rolls that were removed. The vacuum transfer machine includes a hood enclosure having an impression cylinder for printing, and transport rolls on opposite sides of the impression cylinder for conveying the corrugated boards through the impression and print cylinders and to the die cutter. The boards are held against the transport rolls and the impression cylinder by vacuum generated in a vacuum chamber in the hood which also contains the transport rolls and the impression cylinder. The vacuum chamber contains a plurality of vacuum dampers for controlling the vacuum area in accordance with the size of the boards being processed. For creating vacuum in the vacuum chamber, high performance "volume blowers" are included on the top of the vacuum transfer machine. Exhaust air from the vacuum chamber is dispersed through filters located adjacent to the blowers. The hood is suspended from a cross-tie which is part of the vacuum transfer machine and adapted to be mounted to the opposite side frames of the existing box-making machines. The cross-tie has a vertically adjustable portion for adjusting the nip of the impression cylinder.

Abstract: The rotor can be moved in translation parallel to the X-X' axis inside the sleeve between a first position where the two means of coupling are matching to drive the helix in rotation and a second position where they do not interact or interact little, so the helix can be displaced relative to the sleeve without the two couplings interacting  The agitator comprises a union (5) which can be mounted in a sealed fashion in a wall (2a) of a receiver with a blind sleeve (10) inside which is fitted a rotor (20) supporting a first magnetic coupling (21). A helix (8) placed around the sleeve is equipped with a second magnetic coupling (17) to drive the helix around an axis (X-X') of rotation. The rotor can be moved in rotation around and parallel to the axis X-X' by a drive shaft (22) which is itself movable in rotation around and parallel to the X-X' axis between two positions corresponding to those of the rotor. The rotor has a central hollow to receive a screw for mounting the rotor on the shaft, with the screw placed along the X-X' axis. The rotor and/or shaft can be immobilized during their parallel movement in an intermediate position. The drive shaft is mounted to slide inside a hollow shaft which is the output from a reduction gear, with the two shafts fixed together in rotation. The hollow shaft has a screw which acts with a fillet fixed to the drive shaft. The parallel movement is controlled by a hydraulic or pneumatic jack. Process of controlling couple transmitted to a magnetic agitator as described above by controlling the position of the rotor along the X-X' axis.
