  • Patent number: 5038484
    Abstract: An apparatus for determining an area of a surface which is traversed and treated by an object during a unit of time is configured for use with a moveable object that has a first axis of a known length. The object is capable of movement along a second axis and the first and second axes define an angle between them which is other than 0.degree.. A signalling means includes a sensor which may be mounted in a motion-sensing relationship to the object for providing a motion signal when the object moves a distance along the second axis. The motion signal has a predetermined relationship to that distance. A timing means repetitively provides a plurality of timing signals, each sequential pair of which defines an interval of time of known duration. A computing means is coupled to the timing means and to the signalling means for receiving at least one sequential pair of timing signals and at least one motion signal.

  • Patent number: 4986254
    Abstract: An improved bar burner is provided for use in a cooking grill having a top cooking area. The bar burner includes an elongate body having a pair of curved ends and a pair of substantially parallel sidewalls extending between the curved ends. A plurality of holes is distributed along each side wall for flowing combustible gas from the interior to the exterior of the body. Each curved end also has a plurality of holes for flowing gas to the exterior of the body. The holes in each curved end are arranged to define an end zone and a pair of angularly facing side zones. The holes in the side zones have enlarged cross-sectional areas, thereby providing improved heat rejection. The cross-sectional areas of the holes defining the angularly facing side zones are generally equal to one another and greater than the cross-sectional areas of the holes distributed along each side wall and in the end zones.

  • Patent number: 4951932
    Abstract: The improved adjustment mechanism for work clamping includes a support member which is arranged for attachment to a supporting arm. The support member has a plurality of serrations which are regularlhy spaced across a generally planar support face formed on the support member. A clamping member is arranged for attachment to a locator block and includes a plurality of serrations regularly spaced across a generally planar clamp face. The clamping member is adjustably movable with respect to the support member. A tension member such as a bolt maintains the serrations of the support face and the clamp face in fixed positional engagement with one another when the mechanism is used for work clamping. The tension member is releasable for permitting adjustment of the position of the clamping member relative to that of the support member.

  • Patent number: 4920612
    Abstract: A knife for filleting fish includes a generally flat cutting blade disposed in a first plane and having a proximal end and a distal end. A generally flat boning blade is disposed in a second plane and has a proximal end, a distal end and a cutting edge. The proximal end of the boning blade is attached to the distal end of the cutting blade in a manner such that the first plane of the cutting blade and the second plane of the boning blade are generally normal to one another. A handle is attached to the proximal end of the cutting blade and the knife thereby permits cutting of a fish along either of two cutting axes without substantially changing the orientation of the knife with respect to the fish.Several embodiments are disclosed.

  • Patent number: 4919116
    Abstract: A gas burner element includes a diffusion chamber and a plurality of burner arms extending from the chamber, the chamber and the arms having a plurality of holes for flowing gas therethrough. A support member is received in the underside of each of the arms for adjustably mounting the element in a spaced relationship from a burner kettle and for maintaining the relationship when mounting is complete. Each support member includes an upper, generally vertical shaft threadably engaged to its associated arm and a lower foot portion disposed radially to the shaft. The spaced relationship between the burner kettle and the burner element are adjustable by rotating the support member in one direction or another, thereby extending or retracting a support member with respect to its related burner arm.

  • Patent number: 4908002
    Abstract: In a combine conveyor of the type with a conveyor surface, elongated carriers across the surface, and endless chains to move the carriers along the conveyor, resiliently deformable slats are used as carriers and such slats are adjustably secured at their ends to the chains by self-adjusting attachments. The slats are preferably flat, of spring steel, angled with respect to the surface, and in a trailing position. The attachments of the slats to the chains include an attachment link on the chain, and a slot-post arrangement for pivoting/sliding engagement. The slots are preferably in the slats. In one embodiment, an angled mounting surface forms part of the attachment link. In another, angling is achieved by twists in the slat near the slat ends.

  • Patent number: 4878777
    Abstract: This invention concerns an improved socket for a control panel of the type having four angled corner pieces, at least two transverse recess members and at least two longitudinal recess members forming a frame. Dimensional stability and torsional rigidity of the socket are greatly increased due to the fact that vertical connecting flanges are bent at right angles along the free edges of the panel-mounting flanges at least in the area of the vertical mounting flanges for mounting of the transverse recess member, and such connecting flanges are connected to the recess-member mounting flanges when the transverse recess members are installed.

  • Patent number: 4879489
    Abstract: An improved radiation-emitting device of the type for containing gas and an electron flow therein between electrodes. First and second separate elongated principal members form an elongated envelope volume having constant cross-sections along its length. The first principal member is outwardly convex and radiation-transmissive and the second is inwardly concave and radiation-reflective, preferably having a metallic inner coating. The members are arranged and configured so that the envelope volume is less than that of a cylinder of similar cross-dimension. Pural electrodes are preferably used.

  • Patent number: 4772207
    Abstract: A kit for visual demonstration of principles relating to carpets and carpet care. The kit includes a horizontal base member, vertical members removably securable in erect position with respect to the base member at their proximal ends, and means on the base member to hold the vertical members in carrying position when not in their erect positions. A highly preferred base member is a transparent rigid box with spaced upper and lower walls, the vertical members being attacked to the lower wall and extending loosely through openings in the upper wall.The method includes applying dirt onto a shaft near its distal end and, when the shaft is erect on the lower wall of the preferred base member, executing a cleaning step. The cleaning step may involve applying a free liquid, which carries dirt through the opening into the rigid box, or rubbing with a damp wiper and then removing the dirty wiper from a position on top of the rigid box.
