Abstract: The invention is directed to a combination heater and electrical generator designed to allow continual use of the heating system in the absence of an external source of electricity. The system shares fuel and electrical inputs and also shares exhaust outputs so to facilitate ease of use installation as well as affording a small installation footprint.

Abstract: The invention is directed to a heat exchange module to help employ usable heat to pre-warm a water supply prior to entry into a tankless water heater. The module comprises an insulated housing having an inner shell having a top end, bottom end and cylindrical middle portion. A first intake attaches to the insulated housing which introduces cooling water from the cogeneration system, while a second intake feeds the water supply coils (positioned within the insulated housing) to effectuate heat exchange with the cooling water. After heat exchange, a first outlet removes cooling water for return to the cogeneration system, while a second outlet removes the water supply from the cooling coils. Upon removal, this water supply may be fed into a tankless water heater. A controller connected to both outlets and inlets optimizes efficient exchange of energy through timing introduction and removal of the water supply from the module.

Abstract: A vibration resistant, energy efficient lamp (10) that is suitable for, for example, ceiling fan operation where vibration is always a concern. The lamp (10) comprises an envelope (12) of a suitable transparent glass, for example, a borosilicate glass, having a substantially spherical upper body (14) with a given diameter D, a substantially cylindrical waist (16) having a diameter W of about 38% of the given diameter; a neck portion (18) having a diameter N of about 31 to about 32% of the given diameter and a threaded base (20) having a diameter B of about 25 to 27% of the given diameter. The base (20) has a skirt portion (22) adjacent the neck portion having diameter S substantially equal to the neck portion (18) diameter N and larger than the diameter B of the base (20).

Abstract: A lamp driving circuit with a floating power supply driver includes a microcomputing unit, a floating power supply driver, and a driving unit. The microcomputing unit and the floating power supply driver are independent integrated circuits and manufactured under a normal voltage. The floating power supply driver is coupled to the microcomputing unit via two independent high-pressure coupling capacitors, instead of sharing the same ground with the microcomputing unit. The microcomputing unit and the floating power supply driver provide at least one low-voltage driving pulse output pin and one high-voltage driving pulse output pin to control the power transistor inside the driving unit. The power transistor turns on/off at appropriate time so that a lamp connected to the driving unit can be lit up by a driving high voltage.

Abstract: A light bulb includes a seat having a first engaging point and a first contact point respectively formed on a bottom face of the seat to correspond to a second engaging point and a second contact point of a light bulb socket. A first end of the first wire engages with the first engaging point of the seat and a second end thereof engages with a first end of a first filament received in the second enclosure. A first end of the second wire engages with the second engaging point of the seat and a second end thereof engages with a first end of a second filament received in the third enclosure. The third wire has a first end engaging with a side wall of the seat and a second end engaging with both second ends of the first and second filaments.

Abstract: A vehicle light bulb has a glass bulb and a base for receiving the glass bulb. A flat portion is used to seal a bottom of the glass bulb, and at least one filament is provided inside the bulb and connected between two legs that extend out the flat portion. The base is mainly made up of a holder and a plate extending from a bottom of the holder, wherein the holder has a top defined with a slot for receiving the flat portion. At least two apertures are defined in a bottom of the plate. When the glass bulb is received in the base, the two legs individually extend through the apertures so as to electrically connect in a socket of a vehicle light, such as a brake light.

Abstract: A panel for self-supporting roof structures of extruded profile elements having at least one main duct closed at the ends with closing members (10) which are made of plastics material and have the same profile as the profile elements and is closed at one end (17). The closing member (10) is of so reduced dimensions as to fit into any main duct in the profile element while allowing some air exchange without the risk of penetration of dirt.The closing member (10) has preferably resilient sealing flaps (12, 13, 14, 15) on two opposite sides, so that one and the same member (10) can be used for closing profile elements of varying size and shape, e.g. as a result of manufacturing inaccuracies. A V-shaped groove encircles the outer surface of the closing member and permits movement of the two parts of a bipartite flap.

Abstract: A hollow panel of extruded plastics for walls and roof structures and having at least two main ducts separated by a secondary duct divided into three or more subducts, one of which is dimensioned so as to accommodate an anchor bar intended for absorbing upwardly directed wind pressure. Each of the main ducts is divided into two channels by a thinner intermediate wall extending through the secondary duct or ducts.A self-supporting arcuate roof comprising such panels provided with coupling members forming together locking ducts wherein locking wedges or reinforcing bands of metal are inserted.The subducts of the panels are designed to resist pressure and torsional forces without separate reinforcing elements.
