Abstract: PR?CIS Dans un outil tel qu'une pelle manuelle ou pelle pour arracher les bardeaux d'asphalte ou autres recouvrements sur les toitures d'édifices, on sait que nous avons une poignée, un manche et une palette de métal, le tout composant une pelle manuelle. Dans la présente invention, nous avons une poignée en forme de "T". Celle-ci permet à l'utilisateur de prendre ses deux mains et obtenir plus de prise ou force sur l'outil lorsqu'il appuiera avec ses mains sur cette poignée en forme de "T" pour obtenir un effet de levier avec l'outil. Pour obtenir l'effet de levier avec l'invention, le point d'appui repose sur deux roues larges et avec empattement large. Ces deux roues éliminent les frictions au sol de l'outil, créant ainsi un effet de roulement qui facilite la poussée de l'outil. Il est nécessaire que le couteau ou lame entre facilement sous les bardeaux d'asphalte ou autres matériaux de toiture afin de créer un effet de levier pour arracher ces matériaux. Aussi la présente invention est composée d'une palette en deux parties principales comprenant un couteau amovible et fixé par des boulons. Ce couteau est aiguisé ou coupé en forme de dents de scie triangulaire. L'autre partie de la palette est fixée à l'appareil et a une forme triangulaire. Elle a deux fonctions: a) faciliter l'évacuation des bardeaux ou autres matériaux, et b) recouvrir les deux roues, créant ainsi un garde-roues pour empêcher que les bardeaux arrachés bloquent les roues. La présente invention est composée d'un manche plus long afin que l'opérateur n'ait pas à travailler en position courbée.

Inventor: MEYST RICHARD P
IPC: C07D401/06
Filed: 1990-12-04
Abstract: This invention relates to a container for carrying a fan-folded stack of plastic sheet assemblies (11) and for allowing the as-semblies to be dispensed, one at a time, while preventing the assemblies from becoming jammed The stack of sheet assemblies (11) is retained behind a construction (45a, 45b) within an elongated chamber having a corresponding shape and slightly larger size. Pulling the forward-most sheet assembly through a narrow channel and an exit slot (23) at the end of the container flexes a trailing assembly past the constriction. A shallow recess (49) in the narrow channel receives a sheet assembly in position to be dis-pensed, and the rear periphery (50) of the recess inhibits the assembly from intentionally being moved back into the container.

Title: Signal routing technique for high frequency electronic systems
Inventor: ABERNATHY MICHAEL G
IPC: G06F1/18
Filed: 1992-06-19
Abstract: SIGNAL ROUTING TECHNIQUE FOR HIGH FREQUENCY ELECTRONIC SYSTEMS                       ABSTRACT    An electrical system wherein the electrical conductive traces on the circuit boards are routed to achieve a balanced net to reduce noise caused by transmission line reflections.  A trace is routed from the source terminal of the net to a balanced junction wherein if there are an odd number of load terminals, or loads, the balanced junction is located at one of the loads.  The remaining loads are grouped into branches wherein each branch includes an equal number of loads.  A trace is routed between each of the loads of each branch to serially connect the loads of each branch together, or, a trace is routed from a center one of the branch loads to each of the remaining branch loads, forming subbranches.  In an alternate embodiment, a balanced subbranch is developed.  The balanced load is connected to a pseudo-balanced load, which further receives an equal number of branches. The 3 pseudo-balanced load is then connected to another pseudo-balanced load, which may also receive an equal number of branches.  This pseudo-balanced load is connected to the source.  In another alternative, two balanced subbranches have their balanced loads connected to a central balanced load.  This balanced load may receive even further numbers of equal branches.  The balanced load is connected to the source.

Abstract: ABSTRACT OF THE DISCLOSURE         The novel signalling post is adapted to be mounted on a flexible  base  member.   The post comprises  an  outer,  hollow, substantially  rigid,  transparent polycarbonate tubular  member.          The  polycarbonate tubular member has a memory for  returning  to its original shape upon impact.  An inner opaque flexible plastic tubular  member is mounted inside the transparent tubular  member and  has  a diameter to fittingly slide  inside  the  transparent tubular member.   The opaque tubular member has substantially  no memory.   The  polycarbonate  tubular member has a  memory  which allows   the  flexible  opaque  tubular  member  to  maintain   a substantially rigid shape and to return to its original shape  if slightly deformed upon excessive impact.  The transparency of the outer  tubular  member allows the introduction of  a  colored  or reflecting  film between both tubular members for simultaneously displaying a visual signal through the transparent tubular member while  the latter protects the film against damages.   The  novel post  is  particularly adapted to be mounted on a  flexible  base wherein the post will be tilted upon impact by the flexibility of the flexible base.

Title: Header transport system
Inventor: FOX THOMAS R
IPC: A01D47/00
Filed: 1992-07-14
Abstract: A header for a combine harvester includes gauge wheels which can be converted from a normal gauge position to a transport position in which the header is wholly supported by the gauge wheels and towed longitudinally of its length. One of the gauge wheels is a single wheel which moves inwardly toward the centre of gravity in the transport position. The other of the wheels is a walking beam system in the working position and forms a transverse axle in the transport position.      Each of the gauge wheels is mounted upon a bracket which can pivot about a horizontal axis from a raised spring biased gauge position to a vertically depending position allowing rotation of the wheel about a vertical axis on the bracket. The header therefore can be transported without the necessity for a separate trailer system.

IPC: B65G23/06
Filed: 1992-12-02
Abstract: Self contained modular powered sprocket drive units for modular link conveyor belt drive systems are disposable across the belt width to mate laminar sprocket ring drive teeth into corresponding mating belt drive surfaces. These modular units may be located along the belt at one or more positions, and are easily removable for maintenance or replacement. A set of sprocket rings are mountable axially in locations that match different belt drive requirements. Provision is made to fix one sprocket drive lamination in place for belt tracking purposes with other sprocket drive laminations floating axially on the drive shaft for dynamic conformation to dimensional changes in the modular link belt when driven. The drive shaft is hollow and contains an electric motor and gear drive train, thus permitting the modular drive unit to be no longer than the width of the driven belt.
