Abstract: A key keeper is held in a belt loop within a small closed bend thereof. The keeper has opposed small and large half loops. Straight side rods connect the loops, being tangent to both. One side rod is split to place keys on the keeper. A trough or clip fixed to a rod at the split releasably secures the rod in place. One loop is about twice the diameter of the other, the large half loop imparting resiliency to the keeper to reduce the need for expensive spring steel wire for the keeper. The keeper is made by winding a continuous wire on a mandrel wherein two end plates with pivots support a large and a small arbor. Each arbor has a cylindrical outer segment in contact with the wire. A clamping bar holds the wire in place after winding, insuring that the wire accepts the shape of the arbors. A cutter then severs the strands of wire on one side of the mandrel, separating the wound length into segments each having the configuration set forth above.

Abstract: A one-piece box blank is cut from a single sheet with creases and score lines dividing the box blank into a receptacle section, a hinge section and a cover section. The cover and receptacle sections both have side and front flaps. The front flaps and hinge section are proportioned such that the receptacle front flap is not totally overlapped by the cover front flap when the box is closed. The depth of the receptacle side flaps adjacent the hinge section is less than the depth of the hinge section. The spaced, scored fold lines separating the side flaps from the cover and the receptacle sections are straight lines, converging from the front flap of the cover to the front flap of the receptacle. If the box is wrapped corner notches are preferably cut in both the one-piece box blank and in a one-piece wrap. The wrap and the blank are combined as they pass through a conventional wrapping machine.

Abstract: A sound damping apparatus has a resilient wall that defines a first volume and rigid wall defining a second or third volume. One rigid wall may be a part of the device muffled. A gas entry communicates with the volume defined by the resilient wall. The resilient wall and the rigid walls are in contact such that gas pressure separates the walls and the wall to intermittently define gas passages between volumes. Fluid within the wall surrounding the resilient wall dampens resilient wall vibration.

Abstract: A light weight handle and head carry a blade with a discontinuous cutting edge. The handle extends at an acute angle to the extent of the blade edge. The handle increases in girth from the head to its free end. The head is slotted to receive the blade in a carrier or guard with a "V"-shaped cross-section. The trough of the "V" is perforated to define slim bands that cross the edge of the blade. The perforate edges are contoured to eliminate drag on the skin and hair of the user. The longitudinal axis of the handle is coplanar with the blade and the handle configuration enables the user to rotate the razor head for ease in shaving difficult areas. The carrier interrupts the skin contact of the cutting edge to prevent slicing the skin.

Abstract: A calculating device for use in conjunction with past performance data conventionally compiled and published on each active thoroughbred horse performing on U.S. racetracks, has three cooperating transparent slides each indexed visibly in terms of racehorse racing time and in speed ratings. The first, or innermost, slide is compound, with time and rating scales and time and distance columns on its obverse face, and assigned weight, age, post position, calendar, track condition and class data expressed in time difference increments on its reverse face. A second slide surrounds the first, and carries a speed rating index extending along the direction of slide motion. An outer slide movable relative to both others has transverse index lines based on seconds of time as expressed on the innermost slide and a table of conventional time performances for various segments of various races.

Abstract: Rolled or extruded box beams and rafters are supported from an existing wall or other structure with the aid of added posts. The beams and rafters extend trasversely to each other, the rafters being secured at the wall by an anchor fascia. A front fascia is fixed to the rafters and also defines a gutter. Roof panels on the rafters are joined along their edges. Each roof panel has a shaped cup edge and an opposite shaped hook edge. The hook of one panel fits into the cup of the adjoining panel. A fastening flange on each cup edge affords means for fixing the panels to the rafters.Preferably the visible bottoms and sides of the rafters and the beams are covered by decorative sheaths, each being an open channel with means for attachment to the rafters and beams. The beams and related rafters are configured to approximate the nominal sizes of conventional wooden structural members, and the exterior surfaces of the fascia, sheaths and anchor fascia are finished in a wood pattern.

Abstract: A plurality of vertical panels have edge slip hinge joint members adapted to unite mirror oriented similar adjacent panels. Each panel has a top clip and a bottom clip. Alternate top clips have swivelled roller pairs which ride on horizontal beams of the door frame header. Bottom panel clips have a guide pin depending into a channel in the bottom track of the door frame. Each panel clip has a platform extending across the top or bottom terminal end of the hinge joint of the joined panel edges. The platforms cooperate to preclude vertical displacement of the panels with respect to one another. Retainers at each of two vertical end rails extend transversely to cooperate with a bottom horizontal restraint rib to limit vertical displacement of the folding door bottom with respect to the door frame. Shaped prongs within each panel clip cooperate with aperture walls at the top and the bottom of each panel to secure the clips thereto and to prevent displacement of the apertured panel from the prongs.

Abstract: A woven cloth of flexible material is masked to expose only longitudinal spaced stripes. A plastic polymer is applied to the exposed material. The striped cloth is draped over spaced supports that are transverse to the stripes. Depressors are applied to the cloth between the supports so that the cloth is substantially sinusoidal in crosssection. The cloth is cured to harden the stripes so that the cloth is still flexible in one direction but only slightly flexible in the other. The cloth is warped, bent or otherwise shaped as desired for application to it of laminar sheets of cloth, metal or wood, then the core and the laminates are joined, impregnated and cured to a rigid structure of desired configuration and high strength to weight ratio.

Abstract: One or more domed valve closure members are operable to open and close ports in the side walls of irrigation channels. Each closure member is cantilevered by a semi-flexible arm from a frame that has a pivot point lying in a plane substantially coincident with the plane of the sealing surface of the valve. A pneumatic bellows, which may be remotely controlled, exerts pressure to close the closure member against the sealing surface of the wall about the port. An adjustable limit stop fixes the degree of opening of the closure member as it swings arcuately away from the valve port to open. A manual control lever with an adjustable limit stop and an over-center locking arrangement replaces or supplements the pneumatic closure arrangement.

Abstract: A self-propelled machine for cutting and moving earth as from a mine face in a shaft or earth from a bank or other natural terrain and having a prime mover vehicle for advancing pairs of conveyor chain sprockets that support and power chain-mounted cutters and scoops. Preferably a separate power source other than the mover vehicle drives the conveyor chain sprockets. Belt conveyors receive earth from the scoops and discharge it away from the machine. The conveyor chains not only are powered separately from the vehicle but travel in a path across the advance of the vehicle. Cutter blades on the forward chain each have a plurality of replaceable teeth on the blade outboard of the foremost chain of the pair. The vehicle or prime mover may be a crawler tractor or other powered apparatus to which the earth-moving apparatus is attached for spatial adjustment with respect to the work.

Abstract: A magnet has a contact face, a registry edge and restraint apertures in which lodge resilient restraints of a magnet holder. The holder has snap fingers and locators for securing the holder to a door stop of a door frame, preferably in an indented section of the stop. The holder cavity has a rocker ridge contacting the registry edge of the magnet, and restraint fingers. The cavity walls, the restraint fingers and the limiting rocker ridge hold the magnet so its contact face has limited freedom to adjust for surface to surface contact with a catch plate or strike on a swinging door. Preferably the magnet holder is shaped with relief openings between the snap fingers, the locators, the cavity walls and the resilient restraint fingers to be conventionally moldable in one piece.

Abstract: A removable foot adapted to friction fit on the ground-contacting shank of a conventional cycle kickstand has a base with a top surface from which a sleeve projects, and a sole that is larger than the ground end of the kickstand. The sleeve fits on the shank and is angled with respect to the foot sole to contact properly the ground for support in accordance with the angle or shape of the kickstand shank.
