Title: High mass low resonance speaker system
Inventor: KLAYMAN ARNOLD I
IPC: H04R1/02
Filed: 1992-04-15
Abstract: HIGH MASS LOW RESONANCE SPEAKER SYSTEM                 ABSTRACT OF THE DISCLOSURE    A relatively small size speaker system is caused to have a lower resonant frequency by providing a partitioned enclosure having an air mass in a first of two chambers that is driven to vibrate as a unit by a pair of speakers on different or opposite sides of the chamber.  Air within the other one of the chambers is driven by only one of the speakers, and thus operates primarily as a spring, whereas the air in the first chamber is driven by both speakers and acts primarily as a mass.  The two speakers are operated in mechanical phase so as to vibrate the air in the first chamber as a unitary mass by imparting mutually aiding forces to the air mass.  This adds a significant amount of mass to  the vibratory  system  and  consequently  lowers resonant frequency.

Title: Method of manufacturing bi-metallic tubing
Inventor: HARDWICK ROY
IPC: B21C37/06
Filed: 1992-06-26
Abstract: ABSTRACT      METHOD OF MANUFACTURING BI-METALLIC TUBING            This invention relates to a method for producing bi-metallic tubing wherein a layer (3,31) of a first metal is metallurgically bonded to the exterior surface of a core component (1,29) of a second metal incompatible for solid state bonding with the first metal by processes other than explosive bonding, the resulting cylindrical bonded composite (15,25) is placed within the bore of a thick-walled tube (33) of a metal compatible for solid state bonding with the first metal and the assembly (39) is heated and expanded by passing it over a profiled mandrel (43).  In passing over the mandrel sufficient pressure is developed at the interface between the bonded composite and the thick-walled tube to form a metallurgical bond at the interface.  When the first metal is the same as the metal of the thick-walled tube the interface is eliminated and a bi-metallic tube consisting of a single outer layer of the first metal with a bonded lining of the second metal is produced.   The method is advantageous for producing large diameter tubes having all outer layer of cheaper metal. for example, steel and a lining of more expensive metal corrosion-resistant metal, for example, nickel alloy.

Title: Dither signal remover for dithered ring laser gyro
Inventor: IGNAGNI MARIO B
IPC: G01C19/66
Filed: 1990-10-22
Abstract: In a dithered ring laser gyro, a dither reference signal is provided to supply information representative of the dither angle or dither angular rate. This information is processed by a signal processor to generate a correction signal which is the sum of (i) a first function of the dither reference signal indicative of the dither angle multiplied by a first coefficient, and (ii) a second function of the dither reference signal indicative of the dither angular rate multiplied by a second coefficient. The aforementioned co-efficient may be either selected or generated based on historical data derived from the dither reference signal and the usual sensor output signal. In turn, the correction signal is subtracted from the usual ring laser gyro output signal to provide a corrected sensor output signal.

Abstract: Mémoire descriptif La présente invention est un système de pare-choc articulé électrique que l'on installe sous le pare-choc de tout transports en commun ou d'autobus scolaire; soit les mini bus, "flat nose" ou à nez allongé. Le but de ce système de pare-choc articulé électrique est d'assurer la sécurité des écoliers, au moment même que l'autobus scolaire s'arrête pour faire descendre un enfant. Ce système de pare-choc articulé se met immédiatement en fonction. Alors l'enfant doit passé devant le pare-choc articulé qui est d'une longueur de 7'0" ouvert. Ainsi le conducteur sera en mesure de voir au devant de l'autobus. Le pare-choc articulé fonctionnera avec les lumières rouges indiquant que l'autobus est en arrêt et se refermera en fermant l'interrupteur des lumières rouges en haut de l'autobus. Il y aura un grillage qui empêchera les écoliers de s'asseoir sur le pare-choc. Ce ne sera pas nuisible à la visibilité du conducteur quand celui-ci sera fermé car le pare-choc articulé ne dépassera pas plus de 4" du pare-choc ariginal de L'autobus.

Title: Method and apparatus for the manufacture of a resealable package
Inventor: SCHMECK ALFRED
IPC: B65B51/10
Filed: 1992-09-24
Abstract: A METHOD AND APPARATUS FOR THE MANUFACTURE          OF A RESEALABLE PACKAGE            ABSTRACT OF THE DISCLOSURE It is often desired to again seal packages, consisting intially of foils hot-sealed with one another, after opening and partial removal of the content in the package in order to at least partially separate the remaining content in the package from the environment.  A resealing area is provided for this purpose besides the hot-sealing area, with which the top and the bottom foil are connected to one another, which resealing area consists of individual closing elements which, fitting into each other, are provided in the two foils.  The foils are not threadlike connected with one another in the resealing area.  Rather dotlike closing elements exist, which also permit a small undercut. They are formed in matrixes without a top die, which matrixes are thereby subjected to an underpressure, whereas the other side of the foil is under an excess pressure.  The deformation is thus brought about purely pneumatically.  The shape of the closing elements can in this manner be designed in many ways and can be easily adapted to the requirements of each individual package.

Title: Positive pressure canister purge system integrity confirmation
Inventor: COOK JOHN E
IPC: F02M25/08
Filed: 1992-11-12
Abstract: Abstract of the Disclosure The tank/canister volume's integrity against unacceptable leakage is either confirmed or denied by a diagnostic test performed by an on-board diagnostic system which includes an electrically operated air pump and a pressure switch. At the beginning of a test, the engine management computer closes the canister purge solenoid valve and operates the pump to begin pressurization of the tank/canister volume. Failure to build to a predetermined pressure indicates a gross teak. Upon attainment of the predetermined pressure, the pump is shut off by the operation of the pressure switch from one state to another. The pressure switch has hysteresis so that if the pressure falls below the predetermined pressure by a certain amount during the predetermined duration of the test, the pressure switch returns to its one state thereby giving a signal denying the integrity. Integrity is confirmed by the pressure switch remaining in its another state during the test.

Title: Automatic beaver dam water control "beaver deceiver"
Inventor: ARMSTRONG LYLE V
IPC: E02B7/18
Filed: 1993-07-13
Abstract: ABSTRACT:    This is a process for controlling the water level ( high & low) in axisting beaver dams for to minimise the damage from th ever increasing water levels. In this invention a flexable hose. 4" to 6" diameter, is laid over a hole dug into the dam at a height that the installer desires the high water level to be. Than about 30 feet of discharge hose is secured below the water on the downstream side of the daM WITH A "T" attached to the end of the hose and a 1/4" screen protecting the and from debrie. Then, about 20 feet of inlet hose is secured under the water with weights attached to it about  3' apart or as needed so as to keep hose on the bottom, on the upstream side of the dam. The intake  and is a cluster of four inlets created by attaching 3 "T"s together. this also to minimise the danger of the end becoming pluged, than a 1/4 " screen is wraped around the end  to further protect it from being pluged up. The and is than securly attached to a steak which is  driven into the bottom and pushed in to a level that will place  and keep the suction and located at the level at which the installer wants the low water level to be maintained at ( preferably about 8 to 10 inches below the high water level ) This instalation creates a  siphon which will start to siphon water when the water in the dam rises above the top of the siphon and will stop siphoning the water when the water reaches the intake of the sipnon (low level The process then will keep repeating itself as the water in the dam rises again above the top of the siphon.priming it again and pumping back down till air again enters the inlet when the water is lowered to the inlet. The water in the dam is thus maintained between the High and low   levels determined at the instalation of the siphon..A siphon of course requires no energy to operate, and will shut itself on and off automatically as the after level rises over top level and then falls below the inlet level. The beavers instincts are foiled by this because it can not detect a hole in the dam and will not be able to stop the pumping action.
