Abstract: An accessory or attachment device for existing or newly manufactured internal combustion engines bleeds incompletely burned combustion products from the engine exhaust upstream from the exhaust manifold and returns or recycles the combustion products through the carburetor to the combustion chambers of the engine where complete burning of the products takes place. Carbon monoxide in the final exhaust from the engine is reduced almost to zero and substantially the full energy present in the hydrocarbon fuel is utilized, rather than being wasted into the atmosphere as occurs in conventional engines. The device subjects the recycled combustion products to violent agitation and comminution before returning them through the carburetor to the engine fuel induction system.

Abstract: The magazine tip guide of an automatic loom filling winder is subjected to constant pounding by the quill tip support as quills are transferred into the shuttle. Eventually a section is broken out of the magazine tip guide and the replacement of this component and its refitting on the loom winder are costly and time consuming. To avoid the necessity for replacing the entire tip guide, a simple and economical part is installed between the outer side of the tip guide and the rockable quill tip support, and this repair or replacement part has a slot which registers with the slotted portion of the magazine tip guide which has been fractured. The normal operation of the magazine tip guide and quill tip support is not interfered with by the invention.

Abstract: The apparatus for dosing metered amounts of dense pasty pharmaceutical substances and for inserting same into gelatine capsules, comprises an extrusion press which extrudes a layer of substance having a uniform density and a predetermined thickness or height. A hollow punch presenting a cavity is dipped inside said layer for its whole thickness or height, so as to take out of said layer, due to the inherent viscosity of the substance, a predetermined dose of the substance itself. The hollow punch is then positioned above an empty capsule half, and the dose is discharged into the said capsule half by means of an ejecting piston slidably movable at the interior of the hollow punch. The extrusion press comprises two parallel walls, one of which is adjustable so as to vary its distance from the other wall, thus varying the thickness of the layer of substance being extruded.

Abstract: A pumping device whose functioning resembles the action of the natural four chambered heart is constructed as a total cardiac replacement unit. An internal electrical drive motor adapted to be powered by radio frequency induction across intact skin drives an eccentric rotary element which in turn causes oscillation of pivoted vanes whose movements cyclically compress a pair of blood compatible sacs which simulate the left ventricle and right ventricle of the natural heart by pumping blood through the aorta and pulmonary artery, respectively. As in the natural heart, stroke volume of each ventricle is independent of the other and is a function of right atrial and left atrial pressure and volume. Additional embodiments of the invention feature modified driving means for the pumping vanes.

Abstract: A pulsatile flow pumping unit adapted to serve as a total cardiac replacement device, a cardiac assist pump for orthotopic placement, for extracorporeal application in conjunction with a membrane oxygenator for cardiopulmonary support during surgery or critical illnesses, for pulsatile flow coronary artery perfusion, and for filling and emptying of an aortic diastolic augmentation balloon for cardiac assist is provided. The pumping unit features simplicity of construction, comparative economy and reliability by utilizing a minimum number of working parts including a large diameter slitted rotary driver and cam operated follower means which avoids close machining tolerances and attendant high cost of manufacturing.

The mill table is programmed to move the work piece relative to the stationary tool in the required directions for machining.

Abstract: A semi-automatic sporting rifle, firing high powered center fire cartridges, is easily and quickly convertible to a 22 rimfire rifle without loss of feel or balance. The dual purpose rifle features a short stroke, gas operating system which is rendered inactive when the rifle is converted to 22 rimfire action. In the conversion, a locking bolt assembly and magazine for high powered ammunition are replaced by a non-locking bolt and a combined cartridge adapter and magazine holder for 22 calibre rimfire ammunition. The principal components of the firearm, including barrel, receiver, firing mechanism, action spring, magazine latch, bolt connecting link, charging handle, sights, stock and forearm, are common to both forms of the rifle. The conversion may be accomplished by using only a pointed object, such as a bullet point or ball point pen.

Abstract: A single rotationally driven cam plate having cam follower grooves in its opposite faces generates and coordinates the movements of all apparatus components necessary to the product molding apparatus. The advancing and retracting of mold halves is coordinated through the rotating cam plate and directly associated mechanisms with the cutting off of pieces of moldable stock and the carrying of such pieces to a position for charging the mold. In conjunction with these operations and in properly timed relationship, the stock is advanced to a new cutting position. Certain of the cam driven mechanisms also act in proper sequence to advance molded product encapsulating films through a film guidance means and to operate film clamping and severing devices in such a way that the encapsulating film is always severed midway between molded product units.

Abstract: A floating plant guard or fender for cultivators formed of rod components straddles small plants in rows and prevents the plants from being damaged or buried by the action of the cultivator tines in the soil. The plant guards are wider at the front than at the back so that they can funnel fine soil around the plants without covering them to provide a mulch and to smother small weeds close to the plants. The rod construction renders the plants visible to the farmer on the tractor at all times. The guards have a floating suspension from a tool bar means so that they will not be obstructed by ground irregularities or foreign objects. Adjustable side grid attachments for the guards allow finer grading or sifting of soil by regulating the spaces between bars of the guard bodies.

Abstract: Right angular corners of knock-down reusable multipanel containers are releasably joined in assembled relationship by metal reinforcing plates and right angular spring clips which span the corners. Formed terminals on the clip arms are received by apertures of the reinforcing plates. One such aperture is relatively large to receive a release implement and the adjacent clip terminal is slotted to receive the release implement after insertion thereof through the aperture. The aperture of the other reinforcing plate is relatively narrow to prevent dangerous separation of the clip from the container following the release of one arm thereof by means of said implement.
