Title: Improved valve for closing the outlet from the housing of an endless screw conveyor
IPC: B65G53/46
Filed: 1986-04-23
Abstract: Improved valve mechanism for an apparatus for conveying particulate solid material. The conveyor apparatus includes a casing which has a core through it with an inlet for the material to be conveyed and an outlet. An endless screw impeller is mounted in a rotary manner in the casing by means of front and rear bearings, the rear bearing being located close to the inlet. The material is discharged from the casing via an outlet which is coaxial with a discharge chamber. Pressurized gaseous fluid is supplied to the discharge chamber in order to entrain and convey the particulate material through a pneumatic conveyor pipe which is connected for flow to the outlet from the discharge chamber. A description is given of an improved valve mechanism which closes the outlet of the casing. The valve is pushed into the closed position by a weight and is opened by the material which is made to advance by the endless screw impeller.

Title: Soil tilling implement.
IPC: A01B35/16
Filed: 1986-06-19
Abstract: A rotary incorporator for one pass incorporation of chemicals or small grains in previously tilled soil. The incorporator includes two rows of aggressive, large diameter spider wheels supported from a toolbar for rotation in the soil about axes offset at an acute angle to the transverse direction. The spider wheels, arranged to balance the forces transmitted to the toolbar, are angled in opposite directions on each half portion of the implement, with the wheels of the trailing row angled in opposite direction to and offset transversely with respect to the forwardly adjacent wheels in the forward row. The innermost wheels of each of the two rows are more widely spaced and smaller in diameter than most of the remaining wheels, and two additional smaller diameter spider wheels are centrally located between the innermost wheels and cooperate therewith to provide good incorporation and a smooth seed bed without hilling or chemical banding. A smaller diameter, depth limited spider wheel on each outermost end of the implement feathers the effect of the angled wheels. The spider wheels include tines having a concave soil working surfaces for good mixing and soil moving action and a large gullet area for good trash shedding and throwing characteristics.

Title: Sdh rejustification
IPC: H04J3/00
Filed: 1991-05-23
Abstract: The invention concerns a method of pointer processing a digital TDM data stream at a node of a synchronous SDH transmission network so as to justify the data stream on transmission, the data stream having a specified line frequency and being composed of frames, each frame containing a reference word, and the node of the transmission network having a node frequency, the method comprising storing the incoming data stream in a buffer store at the node, using the line reference of the incoming data stream to extract a data pointer from the data stream for each frame, which data pointer indicates the location of the reference word of that frame in the buffer store, and characterised in that a timing pointer is extracted from the incoming data stream utilising the line reference and a line clock the frequency of which is a multiple of the line reference; the timing pointer so extracted is converted into a reference value by utilising the node reference and a node clock; the reference value is utilised to generate a node timing pointer; the node timing pointer is compared with a read address and data pointer; and read-out from the buffer store is justified in accordance with the results of the comparison.

Inventor: BORLE LAWRENCE JOSEPH
IPC: H02M7/5387
Filed: 2000-11-01
Abstract: L'invention concerne un circuit de commande pour un régulateur de commutation comportant un inducteur. Ce circuit de commande comprend une première unité de commande J pouvant être commutée entre une tension positive et une tension alternative par le biais de l'inducteur, et une seconde unité de commande K pouvant être commutée entre une tension négative et une tension alternative par le biais de l'inducteur. La première unité de commande J et la seconde unité de commande K fait normalement fonctionner en alternance le régulateur de commutation dans une mode de commutation à demi-pont afin de produire une forme d'onde de courant dans cet inducteur, la temporisation des instants de commutation étant calculés de manière à exécuter un signal d'erreur de courant moyen quasi nul, fonction de la temporisation des instants de commutation. Lorsque l'exécution de la mesure du temps de passage par zéro désiré d'un signal d'erreur de courant indique ce temps de passage va être dépassé, le circuit de commande démarre l'unité de commande inactive de la première et de la seconde unité de commande J et K pour que celle-ci fonctionne lorsque le temps de passage par zéro désiré a été dépassé, afin d'amener rapidement ce signal d'erreur de courant au passage par zéro. Les première et seconde unités de commande J et K vont faire fonctionner le régulateur de commutation dans divers modes de commutation à demi-pont jusqu'à ce que l'on puisse déterminer que le temps de passage par zéro désiré du signal d'erreur de courant soit atteint juste après que l'activité du mode de commutation à demi-pont du régulateur de commutation ait repris.

Title: Systems and methods for stabilizing a targert location within a human body
Inventor: KRAG DAVID
IPC: A61B17/32
Filed: 2000-11-17
Abstract: A system and method for bracketing a tissue volume (22) and later locating the bracketed tissue volume. The system includes a plurality of markers (30) and a probe (32) and detector (34) for use in locating the markers by providing information useable by a surgeon that is representative of changes in the proximity between the probe and the plurality of markers. The markers have various detection characteristics, e.g., they transmit gamma rays, that are detectable by an associated probe and detector. The tissue volume is removed by manipulating a cutting tool based on the proximity information provided by the detector which can be used by the surgeon to define the boundary of the tissue volume. A two-part cutting tool (200) is provided for removing the tissue during removal. The system and method of the invention are particularly useful in bracketing and then removing a tissue volume from amorphous, pliable tissue such as breast tissue.
