Title: Aerodynamically-induced wing-flapping for the  propulsion of ornithopters
Inventor: ATRAGHJI EDWARD THE PLAIN HOUS
IPC: B64C33/02
Filed: 1982-07-02
Granted: 1985-03-05
Abstract: ABSTRACT           This invention relates to an ornithopter employing aerodynamically-induced wing-flapping as a means to reduce the input power required for its propulsion.  Most existing designs of ornithopters employ direct mechanical means in one form or another to flap their wings.  Such arrangements place a high demand on the pilot/engine in view of the large inertia of the virtual air mass set in motion by the flapping wings.  The intent of this invention is to employ the increase in the lift force generated on the outboard wing segment, when the latter is yawed forward, to lever the whole wing upwards away from its spring-restrained initial position.  The downstroke is achieved by a reverse torque which develops as the impulsive lift force on the outboard wing segment diminishes when the latter's forward sweeping motion is slowed down or halted.  When a suitable speed is reached the stick (15) is pulled back which cause the outboard wing segment (3) to be flicked forward in a yawing motion generating impulsive lift.  The impulsive torque forces the whole wing upwards against the pull of the restraining cable (7) and spring (8).

Abstract: D-5,115 APPARATUS FOR INDICATING INJECTION TIMING AND          FUEL PER STROKE IN AN INTERNAL COMBUSTION ENGINE            Abstract of the Disclosure Apparatus for indicating timing and fuel/ stroke in a pulse fuel injection system for an internal combustion engine, especially a diesel engine, includes a magnetic piston axially movable in a cylindrical bore in a fuel line to and from a stopped position blocking an inlet.  The piston is included in a magnetic circuit including an actuating coil having an inductance varying with piston position.  Circuitry provides a DC current pulse to the coil prior to injection to move the piston to its stopped position and then provides an AC current to the coil and monitors the voltage and rate of change of voltage thereacross.  Change of voltage past a first reference is sensed to generate an injection timing signal; and decrease of rate of change of voltage past a second reference with voltage past the first reference triggers sensing of the voltage as a signal indicating fuel quantity per injection stroke.

Abstract: ABSTRACT            A composition useful for treating herpes simplex viral infections in humans comprises about 102 to 108 I.U. of human interferon, about 0.1% to about 20% by weight of an antiviral surface active agent and a physiologically acceptable carrier.  Preferably, the interferon-containing composition comprises about 104 to 106 I.U. of human leukocyte interferon, about 1% to 5% by weight of a non- ionic surface active agent having at least one ether amide linkage, and a physiologically acceptable carrier.  These interferon-containing compositions are useful for treating herpes simplex viral infections in humans by topically administering an effective amount of the above-identified interferon-containing antiherpetic composition to the affected area.  Preferably, an effec-tive amount of the interferon-containing antiherpetic composition is topically administered to the affected area during the prodromal stage of viral multiplication. These interferon-containing compositions are usefully applied to the genital area of a human and, when so applied, would appear to be useful as a prophylactic for or in the treatment of in situ cervical carcinoma, since there is some belief that herpes simplex infection might be a co-carcinogen or a background etiological agent which might lead to in situ cervical carcinoma. A special aspect of the use of these interferon-containing compositions is the use of these compositions in the treatment of skin malignancies, pre-malignant skin lesions and skin diseases, such as herpes zoster and psoriasis.   These interferon compositions are also useful in the treatment of basal cell carcinoma, squamous cell carcinoma or squamous carcinoma, actinic keratosis and leukoplakia.

Abstract: FITTING FOR CONNECTING CIRCUMFERENTIALLY RIBBED INSULATING TUBES OF PLASTIC                           ABSTRACT OF THE DISCLOSURE         A fitting for connecting tubes which have circumferen-tially extending axially spaced ribs with recesses defined be-tween the ribs comprises a socket member which advantageously has a cavity at one end of smaller diameter than a cavity at its opposite end which is adapted to receive the tube.  The ledge is formed  between the two cavities and a resilient member such as a sealing sleeve is disposed against the ledge at the inner end of the larger diameter cavity.  The tube to be connected is positioned in the larger diameter cavity against the sealing sleeve such that its ribbed circumference underlies the slot in the larger diameter cavity which is closable by a locking fit-ting.  The locking fitting includes an inner end which is adapted to be secured to the socket and which in one embodiment includes a bending strip which is affixed to the socket and supports the remaining portion of the locking lid at an acute angle with re-spect to the exterior surface of the socket.  The locking lid at its opposite end includes a bevelled lip which is engageable under the interior surface of the opposite edge of the slot.  The lock-ing lid includes one or more projections or ribs at its interior surface which are spaced apart  so that they each engage in a recess between the ribs of the tube.  After the outer bevelled lip of the locking element is engaged beneath the surface of the edge of the socket member bounding the slot the tube is locked in position within the fitting.

Abstract: WARNING DEVICE FOR HELICOPTER            ABSTRACT    A warning device, for a helicopter with a tail rotor and a mechanical protection device therefor, for giving during emergency power-loss landings a flare signal to the pilot to initiate flare followed by a tail/ground contact warning signal when the helicopter tail approaches too closely the ground.  The term "flare" refers to nose-up, tail-down attitude of the helicopter, followed by levelling out immediately before ground contact.  The warning device comprises in one embodiment a height-finder with two switchable transmitting/receiving antennas mounted at the helicopter tail to produce respectively, when switched into use, a height-finding beam backwards and obliquely downwards or forwards and obliquely downwards.  Height signals obtained initially using antenna are processed by computing means and initiate at a predetermined initial flare altitude a flare warning signal whereafter height signals from antenna are used to determine the sink rate of the tail and in dependence upon this sink rate and the instantaneous height, a warning signal is initiated if this corresponds to a predetermined relative relationship.  The higher the sink rate, the greater is the height at which the tail/ground contact warning signal is initiated and vice versa.     In a second embodiment, the height-finder uses a single beam the main axis of which extends backwards and obliquely downwards but of which the lobe pattern is broad enough such that vertical height measurement can be made with the helicopter in both the flare and pre-flare situation.
