Abstract: A door operating system for open and closing a door. The door operating system including a control unit for providing a signal indicative of whether the door is to be moved to an open or closed position. A motor mounting assembly is coupled to the control unit. The motor mounting assembly includes a motor operatively coupled to the control unit. The motor mount assembly further includes a primary chassis having a drive gear assembly coupled to the door and the motor and a secondary chassis isolated from vibrations with the primary chassis, the secondary chassis configured to mount to the motor assembly.

Abstract: A wireless safety system coupled to a door operating system which moves a door between an open and closed position relative to a fixed location. The wireless safety system includes an electric powered safety sensor assembly for detecting an obstruction between the door and the fixed location. An electric energy source is coupled to the at least one electric powered safety sensor assembly configured to generate electric energy when the door moves between the open and closed positions.

Abstract: A tobacco filter device includes a plurality of filter units superimposedly rechargeably filled in a sleeve member, having a bowl member connected to an outer end (smoking end) of the sleeve member and a mouthpiece connected to an inner end (mouth end) of the sleeve member, whereby upon smoking of tobacco or a cigarette as loaded or inserted in the bowl portion, the filter unit or units positioned on an outer portion of the sleeve member adjacent to the smoking end, after being saturated with smoking waste including tar and nicotine, may be pushed outwardly and discarded from the outer end of the sleeve member as thrusted and urged by a fresh (new) filter unit (or units) as recharged into the inner (mouth) end of the sleeve member, thereby still keeping use of those filter units not yet saturated and loaded in the rear portion of the sleeve member, without wasting the useful filter units.

Abstract: An apparatus for making carbon-dioxide snow or frost bar includes a feeding means by feeding liquefied carbon dioxide and a plurality of edible fillers such as juice concentrates into an extruder for extruding the raw materials, a forming device for discharging the extruded product from the extruder to form a dry ice bar at a freezing temperature of the liquefied carbon dioxide, a packaging and storage device for packaging the carbon-dioxide snow bars for storage, sales and final uses.

Abstract: A beverage vessel includes: a hollow stem member having a lower chamber formed in the stem member for filling a first product such as a beverage additive or concentrate therein and a lower conical plug portion formed on a top end of the stem member, and a bowl member having an upper chamber for filling a second product such as water therein and an upper conical socket sealing a bottom of the bowl member, whereby upon an assembly of the bowl member on the stem member to form a stemware by engaging the lower plug portion of the stem member with the upper socket of the bowl member, both the upper socket and the lower plug portion will be broken to mix the first product and the second product with each other for serving an instantly mixed beverage..
