Abstract: A guide and other tools for cutting a bone graft from, e.g., the patella. The guide includes a guiding portion configured to engage a bone cutting instrument (such as a saw with a curved cutting surface), and a bone-engaging portion insertable into a cut in the surface of the bone to position the guiding portion in a selected orientation with respect to the bone. During use, the guiding portion directs the bone cutting instrument to cut the graft in the selected orientation. One of the other tools used with the guide is a spacer which has a bone-engageable portion insertable into the cut in the bone surface, and a surface arranged with respect to the bone-engageable portion and configured to guide a saw in making a second cut in the bone surface parallel to the first-mentioned cut. The guide includes a housing that supports the guiding portion, and arms secured to the housing and on which the bone-engaging portions of the guide are disposed.

Abstract: A knife (12), a holding and releasing mechanism (8) are oriented in the direction of a radius of a chipper disc (19). The holding and releasing mechanism (8) is pushed in the direction of the radius of the chipper disc to release the knife (12) and drawn in the opposite direction to fasten the knife in the chipper disc (19). A power unit (32) with reciprocable spindle (34) selectively engages a holding element (11) of the holding and releasing mechanism (8) to release the knife (12) from the chipper disc (19). A device (36) can be provided for automatically positioning the holding and releasing mechanism (8) to lie opposite the spindle (34) of the power unit (32). The time consumed in replacing the knives is reduced and laborious manual operations can be avoided. The procedure can be automated.

Abstract: An injection system for an internal combustion engine, in particular an engine operating on liquid gas as fuel or fuel component, includes an injection unit for each cylinder for direct fuel injection into the combustion chamber, and a fuel supply system with at least one fuel tank and an oscillating pump element configured as a displacer for delivery of the fuel. The pump element is provided with an elastic sealing element fitted in a housing and which divides a pump chamber into two subchambers sealed tightly against each other, the first subchamber being supplied with fuel via a fuel feed line of the fuel supply system, and the second subchamber being supplied with a secondary medium. The dead volumes of the pump element may be reduced by configuring the pump chamber as an annular chamber at least partially surrounding a shaft moving axially in a cylinder, which shaft is mechanically linked with the sealing element.

Abstract: A method and apparatus are provided for adding controlled and accurate quantities of differing oils, to a polymer processing mixer without substantially contaminating one oil with another. Oils are contained in a plurality of oil supply tanks wherein each tank is fluidly connected to the mixer by an oil supply conduit. The speed of the oil pumped through the conduit is controlled by a variable speed pump motor drive unit. The quantity of oil passing through the conduit is preferably measured by a mass flowmeter and the measurement transmitted to a controller. A multi-directional valve controls the delivery of each oil into the mixer. The controller controls the delivery of oil into the mixer in response to the transmitted measurement, by varying the speed of the pump and opening and closing the valve.

Abstract: An attachment unit (28) to an existing central air conditioning thermostat controller (24) like the ones found in most homes and offices; which provides two independent modes of saving energy, first by turning on a light to indicate when to change the filter and secondly by extending the fan operation for a few minutes without disruption. Uniquely conceived, smaller than the typical thermostat controller, automatic, maintenance free, no batteries or auxiliary power of any kind. Has one button (32) to reset the light (30) after changing the filter and one switch (34) to select the optional extended fan operation.

Abstract: Oral compositions, such as oral gels and toothpastes, containing a novel abrasive.

Abstract: A variable geometry exhaust nozzle is disclosed in which the follower flaps of the first, upstream ring of flaps and the second, downstream ring of flaps have a seal to seal the gap between the upstream and downstream follower flaps throughout the range of movement of the variable nozzle flaps. The sealing device has a plate extending between the downstream edge portion of an upstream follower flap and the upstream edge portion of a downstream follower flap and across the entire circumferential width of the flaps. The plate has an upstream portion pivotally connected with the downstream edge portion of the upstream follower flap and a downstream portion which has a bead pivotally contacting an inner surface of the upstream edge portion of a downstream follower flap.

Abstract: A chair control mechanism having compressible lamellas which when compressed lock a chair back and/or seat in position and when decompressed allow adjustment of the chair seat and/or back, and housing a releasable lock to compress and decompress the lamellas. The lock includes a U-shaped slide member slidable on the same shaft as that on which the lamellas are mounted, and having its cross member pressed against the lamellas and its free ends projecting through slots in a housing side wall. A coil spring between the side wall and connecting member biases the slide member against the lamellas to compress them. A cam connected to the legs of the slide member outside the side wall is moveable to pull the slide member outwardly through the side wall to release the pressure on the lamellas.

Abstract: Cannulas for surgical and medical use expand along their entire lengths. The cannulas are inserted through tissue when in an unexpanded condition and with a small diameter. The cannulas are then expanded radially outwardly to give a full-size instrument passage. Expansion of the cannulas occurs against the viscoelastic resistance of the surrounding tissue. The expandable cannulas do not require a full depth incision, or at most require only a needle-size entrance opening. In one embodiment of the invention, the cannula has a pointed end portion. In this embodiment of the invention, the cannula includes wires having cores which are enclosed by jackets. The jackets are integrally formed as one piece with a sheath of the cannula. The cannula may be expanded by inserting members or by fluid pressure. The cannula is advantageously utilized to expand a vessel, such as a blood vessel. An expandable chamber may be provided at the distal end of the cannula.

Abstract: The invention refers to a rotary filter with a device for separating a liquid-solid mixture, particularly a pulp suspension, with several separate zones, at least one of which is of variable design. It is mainly characterized by the variable design for the length and/or position of the atmospheric zone and the vacuum zone.

Abstract: A gripping device or the like, particularly for gripping hot pans. First and second movable members are formed by molding with structural plastic material. One of the members has a pivot post extending laterally and defining a pivot axis. The other movable member has a tubular pivot member, arranged for a close fit reception over the pivot post to pivotally join the two movable members. At least one pivot post and the tubular pivot member is integral with a movable member. The pivot post has an annular groove, and the tubular pivot member includes a plurality of integral, resilient locking tabs having portions projecting radially inward at a shallow angle to the pivot axis. The two movable members are assembled by forcing the tubular pivot member over the pivot post. The locking tabs are resiliently displaced outwardly during the assembly, and snap into place in the annular groove to positively lock the two parts together.

Abstract: A driving device for driving a fastener (2) includes a centering mechanism (9) for centering and guiding the fastener (2). The centering mechanism includes centering elements (10, 26, 36, 37) that are tiltably or slidably connected to a mounting body (3) to be movable in directions tangential to the fastener. The centering elements (10) have contact surfaces (19) for contacting the fastener (2) that are each substantially parallel to the direction of motion of the respective centering element (10). In this manner, the centering elements (10) cannot be deflected radially away from the fastener, and any forces applied laterally outwardly by the fastener against the contact surfaces (19) are rigidly received and resisted by the centering elements (10) and the mounting body (3) in which they are held.
