Abstract: An adjustable collimator is provided for use in mammography in which there is a mounting ring for securing the collimator to an x-ray source; a collimating cone having a plurality of leaves, each pivotably secured at one end thereof to said mounting ring and positioned in overlapping relationship to one another to define at their opposite ends a substantially kidney shaped opening through which x-rays may be directed to a female breast positioned below said cone; and a collar positioned about and capturing the plurality of leaves and to be raised and lowered along the leaves relative to said mounting ring to adjust the size of the opening.

Abstract: An improved fishhook comprises a hook-carrying member and a line-carrying member pivotally joined for relative movement therebetween. The hook-carrying member is provided with an elongated shank for engagement with a releasing handle for enabling the freeing of the fishhook from a fish caught thereon. Release is effected by maintaining the line-carrying member in a substantially vertical position and using the releasing handle as a lever to provide a mechanical advantage as it is moved through a pivotal traverse. The movement of the handle is translated to the hook-carrying member to enable release of the fish from engagement with the fishhook.

Abstract: A compartmentalized structure for storing cosmetics or the like having an improved construction permitting vertical stacking with structures similarly constructed, wherein depending legs project into side-by-side positions with upper edges of a mounting recess to minimize sidewise shifting in a multi-tier arrangement of the units while a medially located interconnected male and female projection and notch minimize shifting in all remaining directions.

Abstract: An apparatus and method for constructing a completed image from an incomplete selected sample and for the projection of the image onto a surface upon which an article has been affixed so as to permit the viewing of the article as if the same were positioned in conjunction with the completed image. More specifically, the completed image may be formed from an incomplete framing sample.

Abstract: To existing two-part hair curlers, wherein said one part is a small radius-sized cylindrical core member which provides correspondingly small-radius curls or waves, and said second part is a larger-sized outer cylinder which provides larger curls or waves, the within improvements include providing the two parts with a cooperating longitudinal slot and a radial projection which interfit during the telescoping of these two parts together, with the result that inadvertent unraveling of the hair in curled relation on the core is obviated and the strand of hair attached thereto is effectively guided into the slot and thus into a proper position to be wound about the outer unit preparatory to providing said large curls or waves.

Abstract: A static eliminator having an electrical cable for providing a corona field that is discharged by capacitors each having a body and an emitter electrode formed indivisible and as unitary parts of each other and wherein the housing of such eliminator cooperates with the capacitor structures so as to enable them to be quickly and easily assembled in such manner that if, and when, it is desired to vary the discharge at the electrodes, the same may be accomplished by the use of a metallic sleeve or band cooperating with the cable and capacitor.

Abstract: As a requirement for the opening of a lock or similar security device, an operative group of partially series-interconnected switches is required to be completely series-interconnected, i.e. placed in a closed circuit relation. However, in contrast to a typical prior art electric lock, in which the few switches which operate the lock are grouped, in order to obviate unauthorized detection, with "decoy" switches, the within invention uses all switches in the lock-opening circuit, in that some switches are required to be actuated and the remainder not actuated, or otherwise the circuit cannot be completed. Thus, the security of the lock is significantly improved since unauthorized opening thereof requires not just determining the proper switches to actuate, but also the proper switches which should not be actuated.

Abstract: An apparatus and method are disclosed for forming an improved ejection (inner) tube for use in a telescoping tampon applicator. The apparatus and method takes a tubular blank and, in one step, provides an improved ejection tube by forming simultaneously a bead-like rim on one end of the tube, an inwardly turned bearing surface on the other end of the tube, and a plurality of outwardly projecting abutments on the surface of the tube near the bearing surface end thereof.

Abstract: Underlying the present invention is the recognition that a conventional electric motor, which has its rotor move only in passing relation to the stator magnetic field-producing coils, is the significant source of inefficiency delaying the development of an effective use of electrical energy. That is said conventional electric motor's ineffective use of the motive power available from the electrical source, rather than any nominal extent thereof, is what primarily restricts the efficient use of existing electric motors and contributes to unpredictable electrical consumption, short circuits when in a stalled position, loss of directional power when starting with a load that causes a counter-rotation, inability to readily change speed and horsepower output, excessive costs of repair, inefficiencies caused by back EMF and other current losses which may amount to 20% of applied current, poor magnetic design, and other such problems, all of which are solved or obviated by the within improved electric motor.

Abstract: As a replacement for a permanently installed glass window of the sand blast cabinet of a product-finishing apparatus, which window, as might be surmised, is unavoidably scratched by sand or other abrasive particles during operation of the apparatus and thus ultimately becomes difficult to see through, the within invention contemplates use of a clear plastic strip, put up in a supply roll, and so arranged that successive length portions are unwound therefrom, when needed, to provide a window with optimum visibility through which the sanding or product-finishing operation is readily supervised.

Abstract: Mounted adjacent the end of a plastic hose remote from its connection to a kitchen sink faucet or other such water source is an improved hose-pinching clamp assembly of the present invention which enables effective watering of remotely located plants. The significant improvement in performance is that the clamp, during normal watering service, is confined to providing a desirable "soft" stream by a pliable sleeve or tube in covering relation over the clamp, said tube maintaining the clamp partially closed upon the hose so as to restrict flow to said "soft" stream. Prior art clamps, in contrast, can inadvertently be opened too much, and may therefore operate with a watering stream that splashes or otherwise is unsuitable for the purposes intended.

Abstract: Apparatus having fuel combustion cylinders for urging the rods of pistons operating therein through power strokes, and fluid pressure pistons, also operating in cooperating cylinders, which are correspondingly urged during said power strokes through movement causing the production of a pressure fluid which is thereafter utilized, on demand, to do work. In the transmission of said movement-producing forces of said fuel-powered apparatus input to said pressure fluid output, a linkage mechanism is advantageously utilized to provide a pressure pattern in the pressure fluid which starts at an optimum low value and progressively builds up. This effectively reverses the pressure pattern of the combustion fuel which consists of a rapid-expansion gas having an initial maximum value and, due to expansion, progressively diminishes in value.

Abstract: A method which contemplates the application of a porous, fabric-like cover over bird-nesting areas at airports, to serve as a physical barrier preventing the natural use by the birds of any nominal vegetation which might grow beneath same, so as to effectively inhibit continued use of these areas for said bird-nesting activities. This, in turn, minimizes the hazards posed by birds to jet planes using the airport.

Abstract: A door lock, particularly appropriate for a hotel or motel room, which is effectively operated from either the room side or the corridor side to lock the door closed for security purposes, and from the latter or corridor side, additionally is effective to terminate electrical services within the room, e.g. the air conditioner, to thereby minimize the wasteful use of electricity.

Abstract: A partition panel intended for combination with similarly constructed panels in subdividing a room area that obviates prior art difficulties in using cooperating Velcro-identified fasteners. The fastener strip on the panel vulnerable to being inadvertently pulled free thereof upon disengagement of the panels is effectively held thereon by being wrapped about the periphery of the panel; the forces thus are resisted by the longer length of the strip rather than being localized in the smaller portion thereof being separated from the cooperating fastener.

Abstract: A valve in the fuel line of an internal combustion engine of the type which is normally biased to its closed position, causing engine shut-down, but prevented by an opposing oil pressure from doing so; the valve, in effect, therefore being one which promotes engine shut-down in the event of failure in the engine oil pressure. As an improvement to this class of valves, of which the within valve is a significant contribution, the valve has an engine shut-down function related not merely to the required oil pressure at engine start-up, but also to required oil pressures at full power speed as well as intermediate power speeds throughout its contemplated range of operation.

Abstract: The garment parts hereof, namely the garment placket, collar and cuffs, have a smooth, neat appearance, obviating the need even for touch-up ironing, and thus are particularly suitable for wash-and-wear promotion. Moreover, the fabric for these parts, although not possessing "recoverable" stretch and thus heretofore unsuitable for my prior patented sewing technique for achieving pucker-free seams (U.S. Pat. No. 3,453,662), are now adapted to be sewn so as to provide the patented result noted. To a significant extent, this desired wash-and-wear performance is achieved by an artificially created "recoverable" stretch in the lining fabric.

Abstract: A pencil-gripping device or holder which snaps into position about the handle of a telephone handset so that the pencil, or possibly ball point pen, is conveniently accessible for removal therefrom preparatory to use, but otherwise remains supported lengthwise of the handle in an uninterfering position during use of the telephone.

Abstract: In a trash-collecting vehicle in which fork lifts raise the trash container into an elevated dumping position, a safety device is proposed which applies the vehicle parking brakes and thus immobilizes the vehicle against movement when the fork lifts are raised and thus are in a position capable of striking a ceiling projection, door frame, etc., or when a closure on top of the vehicle is also in a raised position and similarly is capable of striking a ceiling projection or the like.

Abstract: A holder for so-called cut photographic film sheets into which the inserted film sheet is provided with an initial position that is readily manually achieved. Specifically, the sides of the film sheet during insertion are advantageously located beneath the overhang of lip structures which project from opposite sides into the film-receiving compartment of the holder. Thereafter, the frame of the holder is closed about the film sheet and, in the process, the film sheet assumes a final mounted position in the holder in which all four peripheral edges thereof are properly confined against movement.
