Inventor: PORTO NEDIO NILO
IPC: E05B37/12
Filed: 1984-02-10
Abstract: Un verrou contient à mi-chemin de son cylindre secret un rebond (5) qui coïncide avec une goupille (13), empêchant la détermination du trou (8) du passage par le bruit produit par le frottement. Pour que la goupille (13) pénètre dans le trou correspondant (8), il faut que le cylindre (2) soit comprimé ou poussé à partir de sa position de rotation, et les rainures du cylindre (2) sont enfermées dans la plaque dentée (9), empêchant ainsi la rotation de celle-ci et par conséquent le passage de bruit créé par la goupille (13) au travers du trou (8).

Abstract: Laminar insulating foam roofing material (eg. phenolic resin foam) having improved dimensional stability and which resists warpage when hot asphalt is applied to one surface thereof during installation,  is disclosed.   A flexible web material such as Kraft paper is bonded to opposing surfaces of the foam material by means of a uniform asphalt coating applied to one surface of the web material, the asphalt being a "sandwich" layer between the  insulating  foam  material  and  said  web  material.    This material is made by the steps of:   (a)   forwardly advancing the aforesaid laminar insulating  foam material between a pair of opposed rolls; and (b)   simultaneously applying a predetermined quantity of a heat absorbing and bonding material to surfaces of two flexible webs on opposing sides of said laminar foam material and bringing said two flexible webs each of which has a coating of said heat absorbing and bonding material applied to a surface thereof, into contact with said opposing surfaces of said laminar foam  material  at  said  opposed  rolls,  such  that  after  said bringing into contact of the insulating foam material and coated web material, said materials bond together to form said laminar material.

Title: Quick-change wheel landing gear
Inventor: DAVIS CHARLES E
IPC: B64C25/02
Filed: 1989-11-17
Abstract: QUICK CHANGE WHEEL LANDING GEAR            ABSTRACT OF THE DISCLOSURE    A quick change wheel landing gear assembly (10) is provided as a replacement for a skid landing gear system on a vertical take-off and lending aircraft.  The wheel landing gear assembly (10) includes a pair of spaced-apart fore and aft longitudinal tubes (16, 18) attached to a pair of short, spaced-apart cross tubes (20, 22) that are adapted to mount on the structural saddles (12, 14) used to mount the skid landing gear on the underside of the aircraft.  The longitudinal tubes (16, 18) are connected together at the forward end for mounting a fully swiveling nose gear (26) thereto.  Aft main gear wheels (30, 32) are mounted on cantilever landing gear legs (34, 36) that extend laterally from the longitudinal tubes (16, 18) adjacent the aft cross  tube (22).  Landing loads on the landing gear may be absorbed by resilient springs (25), deflection of the gear legs (34, 36) and the aft cross tube (22), torsion of the fore and aft longitudinal tubes (16, 18), or any combination of these actions.  Resilient springs (25) are used in the landing gear assembly (10) to attenuate fatigue stresses in conjunction with the deflection of the longitudinal (16, 18) and cross tubes (20, 22) of the gear assembly (10).  The wheel landing gear assembly (10) is designed to be mounted on existing aircraft structural saddles and to retain many of the desirable features of a said landing gear system, including low cost and easy maintenance.

Abstract: Abstract of the Disclosure:         In a data transmission system where a first signal partially leaks as an echo from a first transmission line to  a second transmission line through a hybrid circuit to form a mixed signal of the echo and a second signal on the second transmission line, an echo canceller is used for cancelling the echo by producing an echo replica at a transversal filter according to filter coefficients and subtracting the echo replica from the mixed signal.  In order to reliably generate the filter coefficient for a reduced time duration, a series of autocorrelation coefficients of the first signal and a series of cross-correlation coefficients between the first and the mixed signals are calculated at calculators and the filter coefficients are determined from both of the autocorrelation and the cross-correlation coefficient series at a coefficient determining circuit.  The coefficient determining circuit may be an arithmetic circuit for solving simultaneous linear equations.  Another circuit for determining the filter coefficients may be a circuit where a first filter coefficient is determined by detecting the maximum value and the corresponding delay time from the series of cross-correlation coefficients, making a fresh series of cross-correlation coefficients with reference to the maximum values, the delay time and (Abstract of the Disclosure continued) the first filter coefficient, then, determining a second filter coefficient from the fresh series.  Then, filter coefficients are determined by repetition of the similar operation.

The prongs taper and are nonperpendicularly oriented relative to the plane of the  substrate.   Each  prong  has  an  engaging  means  projecting laterally from the periphery of the prong.  The free formed prongs are manufactured by the process of depositing liquid material onto a moving substrate, stretching the liquid material in a direction parallel to the plane of the substrate and severing the stretched material to form the distal end and engaging means of the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent garment, specifically a diaper, is also disclosed.

Abstract: Rotating displays include rotation mechanisms which allow the displays to be easily rotated by consumers, yet automatically returned to one or more desired positions when released by the consumer. Holders for the display are affixed to turntables rotatably mounted upon a base wherein the turntables are attached to a biasing means capable of exerting a sufficient torque upon said turntable, relative to said base to cause an angular acceleration of said turntable toward a predetermined desired orientation.  In preferred embodiments, the amplitude of the torque may be adjusted, depending upon the moment of inertia of the display, to cause a predetermined angular acceleration.  The number and placement of equilibrium orientations may be selected based upon the desired geometric configuration of the display with which the rotation mechanism is to be used.

Title: Rotating blade damper with blade lock and stop mechanism
Inventor: HILL JAMES R
IPC: F24F13/15
Filed: 1990-10-02
Abstract: ABSTRACT OF THE DISCLOSURE       A rotating blade damper for an air handling system, the damper having a perimetrical frame and a blade or a plurality of blades each of which is rotatable with respect to the frame between a flow permitting position and a flow blocking position.  Each blade is biased toward its flow blocking position but is normally retained in its flow permitting position, for example, by a fusible link.  In the event of a fire or other condition of excessive temperature the fusible link of a damper incorporating such a product will fail and each blade will rotate to its flow blocking position.  A stop and lock mechanism is provided to stop each blade in a predetermined open or flow permitting position and to securely lock or latch each blade in its closed or flow blocking position.  The stop and lock mechanism includes a disc segment which is carried by a blade rod, at a location outside of the damper frame, and a slide plate which is positioned between the damper frame and the disc segment.  The slide plate is slidable with respect to the damper frame and the  blade rod between a first position, corresponding to the open position of the blade, in which  its movement is blocked by engagement with an arcuate portion of the disc segment, and a second position, corresponding to the closed position of the blade, in which it engages a stop surface at the trailing edge of the disc segment to mechanically block its return to a position corresponding to the open position of the blade.
