Title: Three-dimensional toy system
Inventor: CHUNG HENRY
IPC: A63H30/02
Filed: 1991-06-21
Abstract: ABSTRACT OF THE INVENTION            A three-dimensional toy system is disclosed which comprises at least two movable, three-dimensional objects.  At least one of the objects is capable of "contacting" the other object.  When the  other  object  is  contacted,  an  information  signal  is transmitted  either  to  the  control means which controls  the other  object  or to  the  control  means  which  causes  the "contact".   In a preferred embodiment of the invention,  this information  signal  is arranged  to pass back to the control means which controls the object which made the "contact".  In this way,  the human participant controlling the first object may contact the other object and the fact of this contact may be either transmitted back to the human participant controlling the other object or back to the human participant controlling the first object.   Therefore, there is indirect communication from one participant to the other participant through the toy system,  and also commutation back to the first participant.          These communication links and loops make the toy system more interesting to play.

IPC: H03H7/20
Filed: 1991-06-25
Abstract: A fast settling, wide dynamic range vector modulator for use in an interference cancellation system or the like includes a quadrature hybrid which receives an RF signal and divides the signal into a primary in-phase component signal and a primary quadrature phase component signal. A first 180° hybrid receives the primary in-phase component signal and provides first and second secondary in-phase component signals which are 180° out of phase with each other. A second 180° hybrid receives the primary quadrature phase component signal and provides first and second secondary quadrature phase component signals which are 180° out of phase with each other. A first switching device selects one of the first and second secondary in-phase component signals, and a second switching device selects one of the first and second secondary quadrature phase component signals. First and second coarse attenuators respectively provide a selectable amount of attenuation to the selected in-phase and quadrature phase component signals. First and second fine attenuators provide fine attenuation to the coarse attenuated in-phase and quadrature phase component signals. A signal combiner combines the fine attenuated in-phase and quadrature phase component signals to provide the corresponding output signal.

Title: Process for optimising fuel combustion with the minimum co emission and device for implementing it
Inventor: DOMBAJ STJEPAN
IPC: F02D19/00
Filed: 1990-02-19
Abstract: (57) Abstract The invention relates to a process for optimising fuel combustion with the minimum CO emission by the prior introduction into the fuel air mixture of a fluid vapour containing water and/or alcohol and by producing a uniform fluid-fuel mixture. In ad-dition, too invention relates to a device for implementing said process. To save considerable quantities of petrol and reduce car-bon monoxide emission, it is proposed to add a vaporous fluid to the air-fuel mixture in a turbulent flow field in order to obtain the smallest possible drops of fuel and to maintain them until combustion. This is done by means of a liquid atomisor which meters drops of liquid into an atomiser-eddy chamber where they encounter a fuel or fuel-sir mixture. The vapour cloud consists either largely of distilled water to which has been added a weak, dilute organic acid and alcohol or of a mixture of equal parts of water, methanol and small quantities of glycerine on the one hand and a methanol-oil mixture on the other.

Title: Office size instrument sterilization system
Inventor: SIEGEL NORMAN L
IPC: B65D81/32
Filed: 1992-01-02
Abstract: The body portion (A) of a small portable sterilizer has a face panel (46) against which a door (B) is selectively closed. The face panel defines an access opening for a sterilization chamber (10) which receives a cassette (C), an access opening for an anti-microbial concentrate chamber (20) which receives a powdered or other sterilant concentrate, and an outlet opening (50) from a microbe filter which filters microbes from incoming rinse water. The face plate and the door define fluid flow channels (48, 52) therebetween for selectively directing sterilant solutions and rinse solutions among the anti-microbial concentrate chamber, the sterilization chamber, and the microbial filter. The cassette is configured to ensure that it is inserted into the sterilization chamber with a unique orientation such that its fluid inlet apertures (114) and outlet apertures (124) are at preselected locations. The door includes generally U-shaped projections (116) which abut an outer surface of the cassette in the sterilization chamber partially surrounding the fluid inlet apertures. The U-shaped projections ensure that the cassette is seated in the sterilization chamber and provide a well which directs the circulating fluids into the cassette inlet apertures. A pair of gaskets (56, 86) surround the active portion of the face panel. A vacuum pump (90) selectively draws a vacuum in an annular region (88) between the gaskets, which vacuum locks the door against the face plate in a sealed, closed position. To assure a fluid tight seal, the gaskets are O-rings which are pressed by the vacuum into V-shaped grooves (82, 84). <IMAGE>

IPC: G01V3/02
Filed: 1992-05-21
Abstract: ZERO CROSSING DETECTION CIRCUIT                 ABSTRACT OF THE DISCLOSURE A zero crossing detection circuit produces an output signal which changes state to indicate the occurrence of a positive-going zero crossing of an AC input signal.   The circuit includes first and second input terminals a current sensitive switch such as an opto-isolator, first and second current regulators, and a voltage limiter.  The first current regulator is connected in series with the current sensitive switch, and the voltage limiter is connected in parallel with the first current regulator and the current sensitive switch. The second current regulator is connected between the first input terminal and the parallel combination of the voltage limiter and the first current regulator and the current sensitive switch.  The first current regulator limits current through the current sensitive switch to a first, substantially constant,  current  limit  level,  and  the  second  current regulator limits current flowing between the first and second input terminals to a second current limit level which is greater than the first current level.   The zero crossing detection circuit offers the ability to sense zero crossings of AC input signals having a wide range of AC voltages.
