Patent CA-2114257-A1 (CA)
Title: Implement drive structure
Inventor: HUTCHISON WAYNE R
IPC: A01B71/06
Filed: 1994-01-26
Abstract: IMPLEMENT DRIVE STRUCTURE                 Abstract of the Disclosure An improved drive structure is provided for use between a lawn and garden type vehicle and a vertically adjustable belt driven, belly-mounted implement such as a rotary mower.  The structure is usable with a standard length engine crankshaft which is mountable to project below the vehicle chassis and power the belt driven mower.  It includes a stub shaft extension that is adapted to carry an electric clutch as well as a pulley for driving a belt entrained around the mower spindle pulleys.  The extension permits positive power transmission to the drive pulley and also allows for it to be mounted substantially horizontal with the implement pulleys as they are shifted vertically in response to height of cut adjustments and/or variation in terrain.  The extension further eliminates the need for jacksheave power relay arrangements commonly used to reduce the angles of drive belt entry and exit into and out of drive and driven pulleys.

Abstract: A drawer partition includes a molded, one-piece, plastic tray with a base wall and upstanding side walls. The side walls have laterally aligned and longitudinally spaced-apart dovetail-shaped grooves in the inner surfaces thereof slidably mateable with dovetail-shaped tongues at the ends of divider panels for dividing the tray into compartments.  Pairs of ribs define slots on the side walls to receive end edges of the divider panels.  Pairs of flexible legs on the bottom edge of the divider panel are snap-fitted into apertures in the base wall to lock the divider panels in place.  The bottom outside edges of the side walls have longitudinal grooves mateable respectively with the upper edges of the side walls of another partition to facilitate guided longitudinal relative sliding movement of stacked partitions.  Each tray has front and rear end portions which respectively have recessed outer and inner surfaces to permit overlapping nesting of the ends of longitudinally aligned partitions.

Abstract: The present invention relates to an optical device for viewing colors on a soap film. These colors are a phenomenon known a light interference. The device has a slide which is displaced into and out of a reservoir of liquid soap by a manual lever.  The slide has a circular hole which is where the film becomes suspended.  When the slide is posed in a viewing position above the reservoir it becomes illuminated by a mirror which reflects a light source onto the film, thereby producing fascinating color and light effects. The image is magnified by a lens prior to reaching the observers eye. The device also has a system for disturbing the soap film in order to produce further color and light effects. This optical device is enclosed in a case which provides necessary alignment of the elements.  It is hand held and operable by children or adults.

Abstract: An automatic corrosion measurement system and method enables rapid measurement and evaluation of corrosion on significant portions of straight and curved pipe sections and other surfaces from several square inches to several square feet, using a laser instrument which projects laser light across a scan area which includes corrosion, and detects reflected laser light therefrom. A positioning mechanism advances the laser instrument along the surface to permit evaluation of a large area, and a processor controls both the operation of the laser instrument and positioning mechanism.  Automatic processing by the processor converts surface condition signals into readily usable output in the form of displays, printouts or maps, for immediate use.

Abstract: In a plastic clip made of two interlocking pieces (1, 10) for closing sausage wrappers, bags or the like, at least one piece (1) is designed as an elongated frame with relatively high side webs (2) in relation to the wall thickness. In the side webs (2) are provided central recesses (4) into which the end of the wrapper gathered together into a plait can be laid. At least the other piece (1, 10), which encloses together with the first piece the wrapper end gathered together into a plait, is provided with a projection shaped as a rib (13) that projects into the inside (5) of the frame and extends parallel to the side webs. The rib (13) ondulates and at the same time exerts a pressure on the plait. A maximum elastic compliance of the clip, thus a maximum adaptability to slightly different plait thicknesses or pressures occurring in the enclosed inner space, is thus obtained, without affecting the resistance of the interlocking connection, and at the same time ensuring a high-quality, constant sealing. In a first embodiment, both clip pieces are identical; in a second embodiment the first piece encloses the plait with U-shaped cut-outs of its side walls which are closed by the second piece.

Abstract: A platform type hand cart includes a molded resin load carrying bed that is universally adaptable for both nesting and non-nesting cart configurations. The cart bed is slightly tapered from its rearward end to its forward end to enhance nestability, has a downwardly and forwardly sloping rear edge to further enhance nestability and includes various groups of mounting pads integrally molded into the underside of the bed for receiving fasteners used to sure wheel assemblies, a hinge assembly and a bumper assembly. Integrally molded reinforcing rod receiving pads may also be integrally molded into the underside of the bed for receiving structural reinforcing rods to stiffen the bed against deflection under load. By providing a single bed member with all of the various mounting pads required for nesting and non-nesting cart configurations, economies are achieved by permitting use of a single mold to produce a single bed adaptable for nesting and non-nesting cart applications. The molded bed is further provided with a protective rounded edge extending over at least a portion of the sides and the rear of the bed to protect feet and ankles of users of carts incorporating the bed member. The bed member includes mountings pads for assembling an elastomeric bumper to the forward end of the bed.

Title: Filter material
Inventor: HEINRICH GUENTER
IPC: B01D39/08
Filed: 1994-11-24
Abstract: The invention concerns a filter material particularly useful in the manufacture of tea bags, coffee bags, coffee filters and the like.  The filter material includes an at least two layer non-woven substrate material wherein the two layers are essentially planar and super-imposed, one layer is composed of natural fibers and one layer is composed of synthetic fibers.  The synthetic fiber layer includes a plurality of individual plastic fibers which are deposited in a heated state on the natural fiber layer.  The plastic fibers fuse with each other and also fuse with the natural fibers of the other layer.  The filter material provides the particular advantage, due to the deposition of the individual plastic fibers on the natural fibers, of covering or closing a large number of pores or ducts in the natural fiber layer.  The filter material of the invention has a low particle discharge since only minimal cross-pores are present in the filter material based on the tangled and closed filter material formed by the arrangement and fusing of synthetic fibers on the natural fiber layer.

Inventor: YAMAMOTO OSAMU
IPC: H01G4/40
Filed: 1994-12-22
Abstract: A high-frequency choke circuit comprises a dielectric layer covered with grounding conductors, a lead line of high-impedance and capacitance lands formed within the dielectric layer, and through-holes connecting the lead line and the capacitance lands.  The capacitance lands are disposed closer to the grounding conductors, resulting in large capacitance with small areas.  The capacitance lands are formed on a layer distant from the layer on which the lead line is formed.          Therefore, unnecessary electromagnetic coupling with other circuits formed on the same layer as the lead line can be reduced.  The grounding conductors cover both surfaces of the dielectric layers that incorporate the capacitance lands and the lead line to thereby shield the circuit formed in the dielectric layers electromagnetically from outside.
