Abstract: A method for formulating music, methods for formulating individual musical elements for utilization in formulating music, and methods for expanding and/or modifying the musical elements for utilization in formulating music. The musical elements are mathematically derived from origination elements as non-limitedly exemplified by intervals, chords, chord progressions, arpeggios, and instruments, thereby providing a vast array of new elements as attained from mathematical manipulations of such origination elements.
Abstract: An intake manifold for a four-cycle internal combustion engine with multiple stages to reduce imbalances in volumetric efficiency and air/fuel ratio. The intake manifold utilizes at least two ram stages coupled by a plenum chamber. The first stage includes a ram tube that carries the air/fuel mixture from the carburetor, or throttle body to the plenum chamber. The second stage includes at least two ram tubes that carry the air/fuel mixture from the plenum to a plurality of intake valves through cylinder head intake ports. The plenum chamber acts as a buffer between each intake valve and the carburetor or throttle body. The air/fuel mixture enters the first stage ram tube and passes into the plenum chamber. These gases then pass into either one of the second stage ram tubes, depending on which cylinder is at its intake stroke. By drawing the air/fuel mixture from the plenum instead of directly from the first stage ram tube, differences in the air/fuel ratio and volumetric efficiency are minimized.
Abstract: The present invention is a bookstand for a book. The bookstand comprises a back panel having a top, a bottom, a front side against which a book can rest and a back side. Projecting outwardly from substantially the bottom of the back panel is a lip panel upon which a book can be placed. The lip panel has projectable therefrom a plurality of page retainers for maintaining interfacing book pages open, with each page retainers having a distal end movable toward the back panel. Such movement of one page retainers is independent of movement of another page retainers, thereby allowing positioning of one page retainers near one interfacing page of an open book and positioning of another page retainers near the other interfacing facing page. In a preferred embodiment, each page retainers comprises a rod having a distal end and a proximal end.
Abstract: A carpet cutting knife guide for cutting overlapping adjacent edges of two pieces of carpet to be laid adjacently on a floor. The guide has two lateral members substantially parallel to each other and spaced from each other. A platform member extends from the first lateral member to the second lateral member and has an opening through which at least a blade of a carpet cutting knife member can pass to thereafter be positioned substantially at the floor. The opening has in conjunction therewith at least one friction fit means whereby a portion of the knife member can be releasably retained. The platform member is constructed of a flexible material such that exerting a force thereon causes the knife member to limitedly move substantially perpendicularly toward the floor. Wheels are provided for manually moving the guide over the overlapping edges of the carpet to be cut.
Abstract: A bullet starter for loading a conical hollow-point bullet into a barrel of a muzzle loading firearm. The starter comprises a handle and an impact member, with the impact member comprising an outwardly protruding starter pin in communication with the handle. The starter pin is insertable into a hollow point of a hollow-point bullet, and has a diameter less than the diameter of the hollow point and a depth greater than the depth of the hollow point. These diameter and depth characteristics assure that only the floor of the hollow point has significant impact contact from the impact member when impact is applied to force the bullet into the barrel, and that the nose of the hollow-point bullet is substantially untouched by the impact member and therefore not deformed. The starter pin can be releasably retained and therefore interchangeable with differently-sized pins.

The remaining film chambers are positioned within the other portions of the receiving chamber and can be individually withdrawn for subsequent placement in the lens-bearing portion of the receiving chamber when the original film chamber is removed.
Abstract: A hand operable, two-component fluid pump for inflating an inflatable penile prosthesis. The pump comprises a high-volume, low-pressure first pump component and at least one low-volume, high-pressure second pump component. Fluid to be pumped to the prosthesis is housed within the first component, and each of the first and second components is in valved communication with the prosthesis and in valved communication with each other. In a preferred embodiment the second pump component is disposed within the first pump component. The pump preferably can be implanted within the user, with the most preferable implantation site being within the scrotal sack.
Abstract: A method for using stent which is a hollow, cylindrical structure made of a synthetic substance which becomes plastic and malleable in a temperature range from 45.degree. to 75.degree. Celsius. The stent is brought to the desired site, for example a stenosed section of an artery, by means of a heatable balloon catheter. The stent is heated at the site to be treated and whilst in the plastic state is expanded through dilatation of a balloon. After being cooled to body temperature the expanded stent retains the form achieved. The body fluids bring about complete biodegradation of the implanted stent.

Abstract: A catheter for treating an obstructed blood vessel comprises an elongated tubular body having an internal lumen, a proximal portion and a distal portion, and includes an inflatable dilatation element on the distal portion thereof. The dilatation element is in communication with the lumen and is adapted to be inflatable and deflatable by the application of a suitable therapeutic tissue dissolving fluid pressurized within the lumen. The dilatation element includes a wall having microporus openings adapted to be permeable by the fluid applied to inflate the dilatation element. The fluid, which is pumped into the interior space of the dilatation element, under sufficient pressure, presses through the microporus wall directly on and into the adjacnet tissue. The fluid tends to dissolve the tissue, thereby treatment time is considerably shortened and the long-term success of the treatment is improved, since the impairing tissue is not only dislodged but also dissolved from the vessel.
Abstract: A balloon catheter for rechanneling stenoses in body passages, in particular of coronary and peripheral arterial vessels, has a microwave antenna provided in the interior of the balloon, which antenna is connected to a microwave generator by way of a coaxial cable. By action of the microwaves on a microwave-absorbing dilatation liquid and/or a metallic coating on the envelope of the balloon, the catheter is heated and the vessel wall is subjected to thermal aftertreatment to prevent restenosis.
Abstract: A guide wire for an intravascular catheter is disclosed. In one embodiment, the guide wire has Doppler means positioned on the distal end, with preferred Doppler means being piezoelectric ceramics or piezoelectric polymeric materials, both having electrical leads connected thereto. In another embodiment, the guide wire has a Laser Doppler means.

Abstract: An introducer valve has a connecting housing enclosing a generally cylindrical elastomeric valve body having a proximal end, a distal end, a central axis, and a central longitudinal opening. The central opening has a proximal aperture tapering inwardly to the central axis and has a distal aperture tapering inwardly to the central axis, and is adapted to receive an elongated guidewire or catheter element. The valve body has an exterior surface which tapers from the proximal end inwardly and from the distal end inwardly generally parallel with the respective apertures (in a somewhat hourglass configuration). The central opening of the valve body is normally sealed closed, and further surrounds and seals a penetrating catheter which is introduced or changed within the valve. The valve further comprises an elastomeric ring which circumscribes the center of the valve body.
Abstract: A steerable catheter having a Doppler crystal at the tip to measure the velocity of blood in vivo--and inferentially the blood flow. The catheter includes two passageways, one passageway being exposed to the blood stream with the other passageway containing the electrical leads to the Doppler crystal. The one passageway is dimensioned for receiving a wire guide for accurately manipulating the catheter. Preferably, the catheter incorporates an inflatable angio-balloon operable to distend the blood vessel in the region of a stenosis. Thus, blood flow can be determined in the region of the stenosis before and/or after the vessel is distended. The passageways are preferably defined by a pair of generally concentric tubes with the Doppler crystal doughnut-shaped and sealingly disposed at the tip of the catheter.
