Abstract: A unitary instrument for protection and retraction of the soft tissues of the oral cavity during oral and maxillofacial surgery has a central handle part and active blade parts extending from the ends of the handle parts at different curvatures, with oppositely and differently curved blade extremities for adaptation to the relatively inaccessible areas of the maxillofacial region.
Abstract: An instrument for retracting soft tissue during oral and maxillofacial surgery has a handle, a palm engaging lesser blade at one end of the handle and a greater active blade which extends at an adjustable angle from the other end of the handle.
Abstract: A fish breeding apparatus is disclosed, which comprises a frame body for the fish breeding framed by connecting rod elastic reinforcements to each other into a polygon at a side number of 4 to 30 through bent couplings, and a mooring cable connected at its one end to each of the bent couplings.
Abstract: The axial flow rotary separator of a self-propelled combine employs dual side-by-side rotors sharing a common infeed opening. Finger-like crop engaging elements of the rotors are propelled in orbits both oblique and eccentric with respect to the separator casings. The rotors are counter rotating and a stream of threshed crop material is delivered towards the bite of the rotors so that it is carried through between the rotors and divided against an opposite floor of the infeed casing. The fingers are disposed so that, as the rotor rotates, the degree of engagement of each finger with the crop material stream varies and so that, while in its principal engagement with the material, each finger propels portions of the crop material stream generally spirally downstream.
Abstract: In the axial flow rotary separator of a combine harvester spiral propulsion of the crop material mat is achieved through the cooperation of helical guide vanes in the separator casing and rotor fingers free to swing axially. The rotor is eccentrically mounted so that each finger fully engages the mat for only part of each revolution. While in engagement, the fingers maintain the circumferential propulsion of the mat but each finger is free to be carried downstream by the mat under the influence of the guide vanes, deflected from its normal free fully radially extending position. On disengagement from the mat, centrifugal force restores the finger to its fully extended position ready for reengagement of the mat.

Abstract: A floating frame member for use in a fish breeding apparatus, which is a hollow rod-shaped elastic body constituting a main part of a gas chamber therein, said elastic body being composed of rubber or rubbery elastic material and reinforced with fiber cords to have an outer diameter of about 279.4-about 609.6 mm (11-24 inches), a thickness of about 12.7-50.8 mm (1/2-2 inches) and a product between a Young's modulus and a sectional secondary moment of 100-3,000 kg.multidot.m.sup.2, and having a ratio of circumferential stress to axial stress of 1.5-2.5 when an internal pressure of 0.1-20 kg/cm.sup.2 is applied to said elastic body.
Abstract: A disposable bird feeder comprises a blister pack of bird food adapted to be suspended by an eye in the backing and to provide a perch for the bird by means formed out of the pack and backing as shown in FIG. 1. This provides a very cheap and disposable bird feeder.
Abstract: Device for packing poultry in a box comprising an endless belt (19) running over a plurality of rolls (14-18) with horizontal axles and provided with spaced apart rows of fingers (20), which are hingedly connected with the belt (19) said belt (19) having an upwardly running part at which the fingers project forwardly and move from the floor with the belt and the picked-up poultry upwardly said poultry in normal position being taken over by a series of substantially horizontal guide cams (25) at the level of the top reverse roll (15) at which level the fingers are withdrawn and move downwardly with the belt while the poultry is taken over by endless belts (27,29) which feed them to a feed regulating device (30) which discharges into a box (36).
Abstract: A surgical clip has projections on its load-bearing portion. Also, a forceps used with the surgical clip is formed with depressions or small holes to receive the projections on the surgical clip.
Abstract: The adjustable chaffer and lower sieve of a combine harvester are replaced by a cob catcher or cob-saving sieve which allows corncobs along with shelled corn to be recovered as a mixture from the harvester rather than separating the corn from the cobs and discarding the cobs. The cob-saving sieve comprises a framework incorporating parallel inclined vanes sufficiently spaced apart to allow cobs to pass therethrough and disposed at an angle to direct airflow from the harvester fan over the surface of the sieve for removal of unwanted material.
Abstract: An adjustable multiple row head assembly for a crop harvester provides cantilevered support arms for a plurality of row head units. The units are adjustably positioned for harvesting crops planted in differently spaced rows. An adjusting device for the row head units provides infinitely variable adjustment, and specifically includes a jackscrew operating between a moveable frame member of the row head unit and the fixed cantilevered support arm therefor. The row head units extend in a fore-and-aft direction with respect to a base and include gathering conveyors driven by sprockets. The conveyors cooperatively form passageways having inlets for the crop, and engage idler sprockets adjustable in accordance with the row head unit adjustment to maintain proper tension in the conveyors.
Abstract: An improved septal splint for maintaining the nasal septum in a desired orientation following reconstructive surgery. The composite splint includes two symmetrical halves, each including a plate member having a planar surface for contacting the septum and a tubular passageway for facilitating nasal breathing during the healing process. In another embodiment, an elastic expander or balloon is secured to each of the splint members such that following their insertion into the nasal orifices, the balloons can be inflated to apply predetermined pressures to each side of the septum. The impregnation of the septum contacting surface of the splint with a hemostatic agent and/or the lining or fabrication thereof from impregnated porcine skin are also contemplated.
