Inventor: BERKHOUT AUGUSTINUS JOHANNES
IPC: A61B8/14
Filed: 1991-03-28
Abstract: Scanner for scanning surfaces with ultrasonic signals, in particular surfaces of parts of the body, provided with a scanner head (5) for the transmission of ultrasonic signals and the reception of the echoes hereof. The time passed between the emission of the signal and the reception of the echoes thereof, is a measure for the penetration depth into the surface. The scanner head (5) fits in a holder (6), which is provided with a foil window (7)  to be fixed against the surface to be scanned, letting the ultrasonic signals pass through. It may be filled entirely with a liquid. The scanner has been fitted with means with which the scanner head may be moved parallel to the surface to be scanned, the ultrasonic signals hitting this surface under a fixed angle. Various constructions for moving the scanner head are included.

Abstract: 5 n7 For the production of roofing tiles or outside wall cladding elements a hardenable plastic mass is fed into a continous row of moulds (8), during which the material feed (9-12), and the row of moulds (8) move continuously or badge-wise relative to each other, viewed in the lengthwise direction of the row. The mass lying in and on the moulds is leveled off in such a way that the upper face of the mass is an extrusion face and the elements are hardened. In order to be able to form a watertight clad surface by the elements without visible overlapping shoulders the shape of the bottom of the elements to be formed is determined by the extrusion face while in the bottom face an overlap wing for the transverse overlap of the elements if formed, and the top face (1) of the ready cladding elements to be formed is formed in such a way on the bottom face of the moulds (8) that in the top face a first shoulder (6) forming the division between the visible face (1) of the elements and an overlap (2) for the lengthwise overlap of the elements is produced, and a second shoulder forming the division between the visible face (1) and an overlap wing (3) for the transverse overlap of the elements is produced.

Abstract: An ATM communications system has two ring transmission lines (0,1) in which network nodes (1-4) are connected for transmission of cells in opposite directions. Each cell contains a first identifier (RK) identifying one of the rings and a second identifier (Pi,i) identifying a path between source and destination nodes. Each node comprises two subsystems one for each ring transmission lines. Each subsystem includes a multiplexer 80,81 for forwarding a cell to a first segment of the associated ring and a cell detector (40,41) for examining the identifiers of a cell from a second segment of the ring to determine its destination. A demultiplexer (50,51) is normally connected to the second segment of the associated ring for terminating a cell received therefrom or passing it on to the multiplexer depending on the destination determined by the cell detector. A fault on the second segment of the associated ring is detected by a fault detector (20,21). In response to the detection of a fault by the fault detector, a connection is established from the multiplexer (81,80) of the other subsystem to the demultiplexer (50,51) of the own subsystem, and the latter is disconnected from the second segment of the associated ring.

Abstract: A novel dental instrument (100) is taught which includes both a laser device and an electronic video dental camera. The teachings of this invention overcome the disadvantages of prior art dental laser instruments which do not provide for other than direct viewing of the treatment area by the dentist, as well as the disadvantages of attempting to use such prior art dental laser instruments together with typical prior art viewing devices such as dental mirrors and dental cameras of the prior art. The dental instrument includes a laser device and an electronic video dental camera is provided having a single handle and a convenient shape, thereby being readily manipulated by dentists who are universally familiar with the manipulation of prior art dental tools. The dental instrument includes a handle to be held by the user, a distal portion which is to be placed inside the patient's mouth, a laser light emission port located at or near the distal end, means for transporting laser light from an external laser source to the laser light emission port, and a camera head located at or near the distal end of the device, with the camera head being formed in order to provide a field of view which includes the portion of the patient which is being treated by the laser light emanating from the laser light emission port.

Abstract: Plutôt que d'être séparés le long d'une seule ligne de clivage située entre leurs extrémités adjacentes, les réseaux de diodes (12) sont séparés les uns des autres sur une tranche (10) servant à leur fabrication, ce qui permet d'établir des lignes de séparation parallèles entre les extrémités de chaque paire adjacente de réseaux à l'aide de rainures tracées (18, 20; 40a, 40b; 48a, 48b) le long des côtés opposés d'une étroite bande inutilisée (16) de matériau de la tranche. La technique de séparation est telle qu'elle permet d'assurer que n'importe quel petit rebord (16) situé sur le plan de clivage se trouve sur la bande jetable plutôt que sur la puce de diode, de sorte qu'un tel défaut ne peut entraver l'espacement bout à bout correct des puces lorsqu'elles sont ensuite assemblées pour former une rangée continue de puces comprenant des sites individuels électroluminescents espacés de manière uniforme.

Abstract: Fil amélioré (100) destiné à stimuler électriquement des tissus musculaires, configurés notamment pour un système d'aide cardiaque commandé par des tissus musculaires squelettiques modifiés chirrurgicalement. Le muscle squelettique est soit enroulé autour du coeur lui-même, soit autour d'une chambre de pompage auxiliaire fixée sur l'aorte. La stimulation électrique est acheminée par l'intermédiaire du fil amélioré (100) afin de provoquer la contraction du muscle squelettique en synchronisme avec la fréquence cardiaque rythmé naturellement ou artificiellement et est minutée afin d'obtenir l'effet hémodynamique désiré. Le fil amélioré (100) comporte une électrode (114, 124) placée dans le muscle squelettique. Le seuil de stimulation du muscle squelettique est maintenu relativement bas par l'action d'un glucocorticostéroïde inséré dans la matière de suture (120). Le fait de placer la matière médicamenteuse dans cette position lui permet de jouer un rôle d'anti-inflammatoire sur la totalité du chemin de la matière de suture (120), et de traiter la zone spécifique de contact de l'électrode depuis l'intérieur du muscle lui-même. La zone spécifique de contact de l'électrode peut également être traitée à partir du côté de l'électrode, en plaçant un médicament similaire à l'intérieur de l'électrode (124).

Abstract: A device for fabricating toilet seat covers from paper sheeting comprises three paper shearing and folding assemblies positioned one over the other, each assembly including a drive roll, as well as two additional compression rolls which shear and fold the sheeting. Three layers of the sheeting are fed simultaneously through rotary cutting rolls, and subsequently to the drive rolls associated with each of the assemblies. While one of the layers is fed to the bottom assembly drive roll, a double layer of sheeting proceeds to the drive roll of the middle assembly. There the double layer of sheeting is separated, with one layer being fed to the drive roll of the top assembly, and other layer proceeding through the other compression rolls of the middle assembly. Completed covers exiting from the superimposed assemblies are collated and transferred by transport and collating belts to a transversely adjustable ejection mechanism where the covers are ejected from the device. In one embodiment, doubly folded covers are made by initially prefolding the sheeting by passing it over a doubling guide and smoothing rolls before feeding the folded sheeting to rotary cutting rolls and subsequently processing it through shearing and folding assemblies.
