Title: Process and apparatus for resin impregnation of a fibrous substrate
Inventor: TAIT ROBERT A
IPC: D06B1/14
Filed: 1991-09-16
Abstract: A B S T R A C T            PROCESS AND APPARATUS FOR RESIN IMPREGNATION OF A FIBROUS SUBSTRATE      An apparatus and a process are described for impregnating a fibrous substrate with a thermosettable resin.  The process involves the use of resin application means comprising a moving surface on which is positioned a liquid-form thermosettable resin in essentially uncured state, passing a fibrous web in countercurrent contact with the thermosettable resin so as to transfer the thermosettable resin into the fibrous web, and passing the resin-containing fibrous web to a heating zone to partially cure the resin and form a prepreg.  The process is particularly suited for application of a solventless resin formulation to a glass web in the preparation of a prepreg for an electrical laminate.  The apparatus includes resin application means comprising a movable surface; means for applying a liquid-form thermosettable resin onto the movable surface; means for advancing, in a countercurrent direction with respect to the direction of motion of the movable surface, a fibrous web to the movable surface and in contact with the thermosettable resin thereon and thence to a resin cure zone; and means not in contact with the opposite side of the fibrous web at the point of resin transfer for maintaining tension in the glass web sufficient to promote transfer of the liquid resin film from the movable surface into the interior of the glass web.

Title: Electromagnetic power relay with actuation slide
Inventor: SCHEDELE HELMUT
IPC: H01H50/64
Filed: 1991-09-16
Abstract: ABSTRACT OF THE DISCLOSURE     A relay with a moveable contact element which is actuated through armature movement transmitted via a slide is switched by the application of torsional forces to the movable contact element.          The torsional forces are generated by the slide pushing the leaf spring contact element eccentrically in the region of one edge so that twisting of the contact element occurs during the switching event.   A lower spring modulus for a spring of predetermined thickness and dimensions result so that a smaller magnetic system and a smaller overall relay is achieved given matching of the spring force curve to the magnetic system force curve.

Abstract: METHOD AND APPARATUS FOR PREPARING THE SURFACE OF A REGION OF SOIL FOR FURTHER TESTING                           ABSTRACT      A method and apparatus for preparing the surface of a region of soil for further testing involves the gradual removal of soil disturbed during the drilling of a borehole.  An initial hole may be bored with an auger having a removable nose cone, then a trimming tool may be pushed into the borehole and rotated so as to gradually and controllably remove the soil as the tool is advanced. This removal of the soil portion disturbed during drilling results in the preparation for testing of a soil sample which is less affected by the drilling operation itself and therefore more representative of the actual soil conditions.

Abstract: Précis Dès que l'enfant arrive devant la roue droite avant de l'autobus (véhicule public), la roue placée juste devant la sortie du véhicule, il est capté par une caméra vidéo qui retransmet immédiatement l'image à un moniteur que le chauffeur surveille. Les enfants (adultes) sont captés par la caméra à partir du sol, jusqu'à la hauteur d'environ 30 pouces de hauteur. Si l'enfant (adulte) ramasse un objet par terre ou encore, s'il se penche il est toujours vu par le chauffeur, grâce au moniteur. Si l'enfant (adulte) tombe ou pour quelconque raison, se retrouve étendu devant le véhicule, encore là, le chauffeur garde un contact visuel. Un détecteur micro-ondes de masse et de mouvements est placé devant la roue droite avant de l'autobus (véhicule public), la roue placée juste devant la sortie du véhicule. Il permet de capter toute masse importante qui passe devant le véhicule, évitant le déclenchement du système par la présence d'un chat, par exemple. Les enfants sont détectés à partir d'environ 18 pouces passés le détecteur micro-ondes. Veuillez noter qu'entre le coin du véhicule et le début du rayonnement du détecteur micro-ondes, l'enfant (adulte) est quand même capté par la caméra vidéo qui permet au chauffeur de garder un contact visuel avec lui. L'enfant (adulte) reste dans le champ du détecteur jusqu'à une distance de près de six (6) pieds, passé le véhicule. Tant et aussi longtemps que l'enfant (adulte) reste dans le champs du détecteur, un signal sonore est entendu par le chauffeur.

Title: Swinging Blade Guard Assembly
Inventor: TERPSTRA DANIEL A
IPC: B27B5/18
Filed: 1993-06-30
Abstract: A swinging blade guard assembly for a motor driven saw blade movable from an upper at rest to a lower operational position is disclosed.  An upper blade guard is fixed to a pivotally mounted supporting arm that carries the motor driven saw blade and upper blade guard.  A lower swinging blade guard is pivotally mounted to the upper blade guard for fully covering the blade in its at rest position and for exposing the saw blade when moved to its operational position.  The swinging blade guard assembly includes an elongated link that is pivotally attached at one end to a frame support and includes a pre-configured slot at an opposite end which receives a slidable pin attached to the lower swinging blade guard adjacent its pivotal mounting to the upper blade guard.  A bearing element is also attached to the upper blade guard in laterally spaced relationship to the pin for engaging an upper surface of the elongated link.  Rotation of the saw blade from an upper at rest to a lower operational position causes the bearing to press against the side of the link while also causing edge surface areas surrounding the pre-configured  slot in the link to press against the pin to rotate the swinging blade guard assembly for exposure of the saw blade.  A pre-configured shoulder on the upper surface of the elongated link cooperates with the pre-configured slot to control exposure of the lower swinging blade guard relative to the saw blade, by facilitating rapid rotation of the guard during initial downward movement of the saw blade with subsequent slower rotation of the guard during the remainder of the saw blade travel.
