Abstract: A valve spring retainer is mounted to the upper end of a poppet valve via a pair of cotters in an internal combustion engine of an automobile. The valve spring retainer has an intermediate portion and an outer flange which is engaged with the upper end of a valve spring. The lower surface has a gap between the outer flange and the intermediate portion to decrease wear which is caused by engagement with the valve spring. There is also provided a valve operating mechanism which has a valve spring retainer which has a projection on the lower surface so as to prevent wear.

Abstract: Novel synthetic suppressor tRNA have been provided which provide read-through of internal nonsense mutations, or which can site-specifically alter translation of transcribed sequences. Uses of the same are also provided in genetic engineering protocols including gene therapy treatment of diseases such as Xeroderma pigmentosum.

Abstract: A gravity assisted lint trap includes a housing having an inlet port formed in a lower portion and an exhaust port formed in an upper portion thereof. A lint collection screen extends within the housing to separate the ports so that air flowing from the inlet port to the exhaust port passes through the screen and deposits lint thereon. The screen is oriented in a non-vertical position within the housing, and located above lint collector, such that lint collecting on the screen will drop by gravity into the lint collector, for selective removal.

Abstract: The rest pillow comprises an inflated flexible substantially rectangular compartment having top, bottom, front and rear portions and opposite side portions. An inflation port is located in the compartment to selectively inflate or deflate the compartment. A strap is secured by its ends to the sides of the compartment for securing the compartment to the waist of the person using it. A plurality of baffles extend from the front interior of the compartment to the rearward portion thereof to prevent the compartment from becoming substantially distorted when the person using the pillow rests his or her head on the top portion thereof. The method of the rest pillow comprises placing an inflated substantially rectangular flexible compartment on the lap of a sitting person, causing the person to lean forward to rest the person's head and arms on the top of the compartment to bind the compartment between the head and arms, and the lap of the person, and to provide resting support for the person's head and arms.

Abstract: An integrated hydrostatic transmission has a housing comprised of two separable elements detachably joined together along a substantially horizontal parting plane. A hydrostatic transmission including a hydrostatic pump, a hydrostatic motor, and a center section is separately mounted within the housing. The center section comprises a generally L-shaped member having a hydrostatic pump and motor mounting surfaces thereon disposed at right angles to each other. A pair of fluid ports is on each of the mounting surfaces, and internal passageways are in the L-shaped member connecting each of the fluid ports on one of the mounting surfaces with one of said fluid ports being on the other of the mounting surfaces. The L-shaped member comprises first and second legs integrally joined and extending at right angles to each other, with the first leg normally extending in a horizontal direction, and the second leg normally extending in a vertical direction.

Abstract: An apparatus for repairing a pipeline includes an elongated flexible tube with one end inverted upon itself to create an outer inverted portion and an inner non-inverted portion connected at an inversion end. An elongated sleeve-shaped liner impregnated with rosin is fitted within the non-inverted portion of the tube member in contact with the interior surface thereof. A plurality of attachment strips are frangible connected at one end to the liner, and permanently affixed to the tube inner surface, such that inversion of the tube member will cause the attachment strips to invert to the exterior of the inverted portion, and thereby also invert the liner to the exterior surface of the inverted portion of the tube.

Abstract: A door closure system for one or more swinging doors includes, in its most basic form, a door closure assembly for a door pivotally mounted on a hinge axis in a door frame. The assembly includes a closure mechanism mounted on the door frame adjacent the door with a rotatable member extending therefrom, an elongated arm having a secured end fixed for rotation with a rotatable member and a free end extending alongside the door, and a roller wheel rotatably mounted on the free end of the arm and extending therefrom so as to overlap the door for engaging it and rolling about a wheel axis substantially parallel to the hinge axis when the door swings about the hinge axis from a first pivotal position to a second pivotal position. This door closure assembly can also be applied to a double swinging door by adding more closure mechanisms and interconnecting them for the desired synchronization. A stop for holding the door open to a set position can also be provided.

Abstract: The fishing lure of the present invention includes a frame and a plurality of soft outer bodies. The appearance of the lure can be altered by interchanging the various bodies. The bodies are removably secured to the frame by eyes which extend from the frame and which can be inserted into eye sockets formed in the soft outer bodies. In this way, the soft outer bodies can be interchanged without untying the fishing line from the frame. The eyes are also removably secured from the frame so that they may be interchanged.

Abstract: A motor or pump includes a stator and a rotor supported for rotation with respect to the stator by a bearing arrangement. The rotor has a cylinder block thereon having radial cylinder bores equipped with radially reciprocable pistons. Rollers on the pistons abut a cam ring fixed to the stator so that the pistons to reciprocate radially to displace fluid when the rotor turns relative to the stator. The stator includes a control device fixed thereon having a pair of fluid passages therein. One side of the control device constitutes a distribution face with outlets therein connecting the fluid passages to the cylinder bores as the rotor rotates. A counterpart fastens to the rotor adjacent the opposite side of the control device so as to define an annular chamber therebetween. A shuttle valve operatively interposed between the passages and chamber ensures that the chamber remains in connection with the passage having the higher pressure.

Abstract: An automated tension infiltrometer including a soil contacting base to which is mounted a porous plate for interfacing the infiltrometer with the soil to be analyzed. A Marriotte column is positioned in the base so that its open bottom end abuts the porous plate. A bubble tower is also positioned in the base and has a bubbling tube operatively connected between its interior and interior of the Marriotte column. The bubble tower is adjustable to provide variable tension to the Marriotte column. First and second transducers are positioned at the upper and lower parts of the Marriotte column and continuously measure pressure changes at those positions while water from the column infiltrates into the soil. By correlating these measurements, improved precision in measuring water level is achieved, which in turn allows improved results regarding deriving soil characteristic information.
