  • Device to effect a step-by-step turning movement of a stand
    Patent number: 4568048
    Abstract: The invention concerns a device arranged to effect step-by-step turning movement of a stand by means of a piston-and-cylinder unit which performs a reciprocating movement during each operational stroke.For the purpose of obtaining control of movements and retainment of the stand during standstills as well as during turning movement of the latter, the device comprises an actuating arm which is pivotable about the center of the stand, and a carrier member which moves together with the actuating arm and, during turning movement of the stand over the intended distance, abuts against one of a number of fixed impact edges spaced peripherally around the stand.

  • Apparatus and process for producing a chain stitched tufted product
    Patent number: 4559885
    Abstract: A conventional tufting machine is provided with a looper control cam which enables it to sew chain stitched tufts. The cam reciprocates loopers which face in a direction opposite to the direction of movement of the backing material, the looper being reciprocated once for each reciprocation of the needle. Each looper catches and holds the bight of the loop being sewn during the period of maximum penetration by the needle and then moves the bight of that loop beyond the needle so that the needle sews the next loop through the held loop, the looper releasing the held loop and catching the inserted loop, thereafter.

  • Apparatus for coating and cutting sheet material
    Patent number: 4554886
    Abstract: An apparatus for coating a wall covering with paste or other adhesive and for cutting the coated covering at its desired length. A coating station, having wall covering supply roll supports, for applying adhesive to the back of a wall covering and a cutting station for cutting the coated covering material at its desired length are fixed to an articulated foldable work table generally at one end thereof. The work table includes spaced side sections defining an aisle and a longitudinal center section normally biased to fill the aisle, but which may be urged toward the coating and cutting stations by body pressure from the waist of the operator and, as the operator walks the covering backward, the center section follows in continuous resumption of its first position to cooperate with the side sections to form a platform for supporting the coated wall covering.

  • Flexible barrier holding and manipulating mechanism
    Patent number: 4553739
    Abstract: A flexible barrier element for a passageway defined by two spaced posts is held in a raised taut position to block the passageway by placement of a hand lever having a lost motion connection with the barrier element in a level position of engagement with a bracket fixed on one post. Swinging of the hand lever to a depressed position relative to the bracket on which it is pivotally mounted slackens the flexible barrier element and lowers it to a ground level position allowing unobstructed passage between the posts defining the passageway. A second bracket on the second post has a flexible barrier element attached to it.

  • Power surge isolator
    Patent number: 4547827
    Abstract: A self-contained fused unit for the protection of electrical appliances against damage caused by abnormal power surges is disclosed. Fuses are selected so that the proper amperage required to operate any appliance can be delivered through the power surge isolator while full protection of the appliance against abnormal power surges is provided. Varistors connected between terminals of the device augment the protective action of fuses in the event that certain kinds of power surges are encountered which are so fast that fuses may not blow in time to protect the appliance. In such cases, the instantly decreased resistance in the varistors assures grounding of the excessive current without damage to the appliance occurring.

  • Radiant wall oven and process of drying coated objects
    Patent number: 4546553
    Abstract: Radiant curved walls enclose opposite sides of a central heating chamber within which objects to be heated and dried are placed or passed along a path of travel. An insulated outer housing surrounds the radiant walls and defines, therewith, a pair of outer heating chambers. Heaters, carried by the outer housing, heat the air in the outer chamber and impellers in the outer chamber circulate that air so that it heats the radiant walls. Vents at the bottom portions of the radiant walls release air from the outer chamber to the inner chamber and an exhaust fan removes the air from the inner chamber. Radiation from the radiant walls heat and dry the objects, more than one-half the radiation being of a wave length of 5 microns or greater.

  • Wheelchair anti-rollback mechanism
    Patent number: 4538825
    Abstract: The customary side hand propulsion ring adjacent to each main wheel of a manual wheelchair is mounted through a lost motion connection between the propulsion ring and main wheel so that the propulsion ring can have limited rotational movement relative to the main wheel. A friction brake drum or partial drum fixed to the wheelchair frame inside of the main wheel is engaged by at least one of a plurality of circumferentially spaced over center friction locking devices pivotally held on the main wheel. Each over center friction locking device is moved by a release element to a non-locking position relative to the drum or partial drum in response to reverse movement of the propulsion ring by a chair occupant. Economy and ease of operation are provided for. The wheelchair occupant need not remove his or her hand from the propulsion ring when operating the anti-rollback mechanism.

  • Dynamic brake for manual wheelchair
    Patent number: 4537415
    Abstract: To substantially reduce the physical effort required to slow or stop a manually propelled wheelchair, the customary propulsion ring attached to the outer side of each main chair wheel is mounted on the wheel for limited inward axial movement under manual pressure and is biased outwardly by spring force. A brake ring of similar diameter near the interior side of each wheel in a plane parallel to the plane occupied by the propulsion ring is connected directly with the propulsion ring. An opposing friction brake shoe attached to the chair frame is engaged by the brake ring to slow or stop the chair whenever the chair occupant pushes the propulsion ring axially inwardly.

  • Fastening device for flexible sheets
    Patent number: 4534089
    Abstract: A pair of cooperating resilient clamping heads of a fastener, removeably clamp edge portions of flexible sheets together, the clamping heads being themselves integrally joined together by a flexible strap. The inner surface of one head is provided with a transverse recess having spaced, opposed, inwardly converging, flanges between which are received the inwardly diverging, opposed surfaces of a locking lug removeably recessed in the recess. The lug and recess have conforming curved linear surfaces which frictionally hold the flexible sheets together. The fasteners are manufactured by extruding a continuous plastic sheet provided with a thin central portion and thicker side areas. The side areas have curve linear portions for forming the conforming recess and locking lug areas. The extruded sheet is cut at transversely spaced portions to provide the fasteners.

  • Pulse combustor apparatus
    Patent number: 4529377
    Abstract: A pulse combustor apparatus including a combustor tube having open ends and containing at least one combustion zone where combustion of a fuel occurs and heat is released, resulting in the formation of a standing acoustic mode with nodes and anti-nodes in the tube. The combustion zone is located approximately half the distance between the acoustic pressure node and anti-node where the acoustic pressure oscillation lags the acoustic velocity oscillation by approximately one-quarter wavelength of the oscillation. Furthermore, the combustion air must flow towards the acoustic pressure anti-node. The fundamental principle relating to the occurrence of the pulsations in the combustor is the interaction between the combustion processes and both the non-zero acoustic velocity and acoustic pressure oscillations at the designated combustion zone location.
