  • Patent number: 4293961
    Abstract: A pulsatile flow cardiopulmonary bypass pump for use outside of the body during cardiac surgery and/or in the period immediately thereafter is disclosed. A grooved spinner is motor driven through a fluid coupling which enables idling of the spinner during diastole. The shell of the pump has a roof to which the spinner drive motor is attached, and the roof can move axially of the shell body and is biased resiliently in one axial direction. The roof of the shell moves as a function of duration of systole and magnitude of afterload, reducing stroke volume in the presence of high afterload. A groove rider having a friction reducing ball bearing drives a ring follower housing during rotation of the spinner.

  • Patent number: 4289068
    Abstract: A high volume refuse compacting apparatus utilizes a commercial horizontal axis ram compactor as a base and upon this unit are mounted in tandem relationship a relatively stationary hopper bin and a coacting power-operated pivotal dumping bin which is elevated to a steep angle to feed the hopper bin with refuse by gravity action. A bottom opening of the hopper bin is in registry with a provided opening in the compactor unit above the ram thereof. Corresponding side walls of the hopper and dumping bins are made shallow to facilitate side loading of the apparatus. A scissoring action of the side walls of the hopper and dumping bins substantially eliminates refuse spillage.

  • Patent number: 4287921
    Abstract: A canister set for dispensing measured amounts of flowable solids has a common support. Each canister of the set has a removable trap chamber for residue solids which may be cleaned out at intervals. The trap chamber of each canister is engaged by a receiver vessel and shifted to a material dispensing position. A mechanism on each canister is engaged and activated by the movable trap chamber to shift a closure slide at the bottom of a material measuring chamber to an open dispensing position where the flowable solids can gravitate into the receiver vessel. Substantially simultaneously an upper closure for the measuring chamber cuts off the flow of material thereto from an overhead storage hopper during the dispensing operation. A spring automatically returns each trap chamber and associated mechanism to its normal position.

  • Patent number: 4281604
    Abstract: A boiler construction is disclosed which eliminates the need for bolting together of internal parts thereby greatly facilitating mass production and rapid assembly procedures. Internal side protectors, in addition to establishing the size of the boiler in the front-to-back direction, serve as support rails for a removable boiler module and as a retainer for fire bricks which are further retained by a firebox grate. Front and back protectors for the boiler interior rest upon the grate support members and are maintained in properly spaced relationship through interfitment with the side protectors. A boiler scraping attachment and boiler tube cleaner are disclosed. A positive releasable retainer arrangement for the slide-in, slide-out boiler module is included.

  • Patent number: 4277045
    Abstract: A stanchion for the support of heavy industrial structures and pipe lines utilizes internal liquid springs for the sake of compactness. The height of the stanchion is standardized within several load ranges for ease of installation. The device is field adjustable to achieve an exact height. The stanchion has a low profile and for stability its height is always less than its base dimension. The stanchion includes a structural bearing active in two right angular planes and the bearing surfaces are of a dry lube type to resist wear. An integral load indicating scale is included on the stanchion. Economy of manufacturing, strength and simplicity of design are achieved.

  • Patent number: 4266489
    Abstract: A high ground clearance tractor during one pass through rows of a standing crop, such as corn, opens a small furrow for a second crop, such as beans, plants the second crop, sprays suitable chemicals on the new crop, and trims the tops of the existing or standing crop. A large energy savings is realized compared to using separate machines for the required operations. The machine is particularly useful in regions having a long growing season. Two rows of a second crop can be planted between each adjacent pair of rows of the existing crop.

  • Patent number: 4265246
    Abstract: A sterile needle with a trailing plastic tube receives telescopically and frictionally within the trailing tube a metal implant bushing sheathed in tissue compatible silicone rubber. A double headed wire extends through and beyone one end of the implant bushing. When the needle and trailing tubing are passed through the scalp for a sufficient distance to implant the silicone rubber sheathed bushing, the headed wire is held against movement of the bushing while the trailing tube is pulled off of the implanted bushing and separated from the scalp. A curved adapter needle may be employed in the initial penetration of the scalp. The silicone rubber sheathed bushing may be wired with or without a top bar for hair piece attachment.

  • Patent number: 4256269
    Abstract: A carpet web is delivered on a conveyor to a pair of parallel bed rolls which turn in unison in a common direction and initially are in close side-by-side relationship. A single upper roll parallel to the two bed rolls and midway between them rotates slightly faster than the bed rolls and turns in the same direction as the bed rolls. The upper roll is biased downwardly by a yielding controlled pressure. A rear side swingable roll at an elevation between the bed rolls and upper roll contacts the rear side of the carpet roll being formed by the apparatus to maintain tension thereon and to resist rearward displacement of the carpet roll during its formation. As the carpet roll gains size, the forward bed roll begins to gradually move forwardly in relation to the rear bed roll and upper roll while the upper roll maintains its position to form a broad stance cradle for the growing carpet roll.

  • Patent number: 4253941
    Abstract: To avoid using salt in a costly flotation separator process for various products of differing specific gravities, a fresh water flotation system is employed having a controlled buoyancy zone in which an induced current or up-flow elevates the product component of lesser specific gravity causing it to overflow a product conveyor divider member and to settle on that side of the conveyor away from the product component of greater specific gravity. The separation of clam meat from clam shells is envisioned.

  • Patent number: 4252357
    Abstract: A wheeled platform provides a storage space for logs below an elevated track supported on standards rising from the platform. A trolley device movable along the track supports an easily adjustable log gripping and release device which is utilized to place logs in a fireplace or in the fire box of a stove or furnace. The user of the crane need not place the logs by hand, thus avoiding the possibility of being burned.

  • Patent number: 4249283
    Abstract: Shucked whole clams are drawn by suction through a delivery tube having multiple bulbous portions and intervening constrictions. In passing through the delivery tube, the clams are subjected to repetitive massage or squeezing followed by sudden release from each constriction into a bulbous zone where the clam is suddenly decelerated prior to entering the next constriction in the delivery tube. The clams with their bellies essentially separated from the remainder of the meat are discharged from one end of the delivery tube into a primary suction chamber and are then propelled through a flush pipe under influence of two converging fluid jet streams somewhat downstream from the delivery tube which exert a further squeezing pressure on each clam while propelling it through the flush pipe and maintaining the required degree of suction in the system.
