| Full Text | FORM - 2 The Patent Act, 1 8 70 (38 of 1970) COMPLETE SPECIFICATION. (Section 10; Rule 13) "LAMP OPERATING ON CARBIDE AND WATER". KULKARNI MAYUR RAJESH (Indian National), having address at National Highway No. 4, Plot. No. 116/18, P. 0. Shiroli, Dist - Kolhapur - 416 122, India. The following specification particularly describes the nature of this invention & the manner in which it is performed: The present invention relates to a 'lamp operating on carbide and water'. Description of prior arts: Currently available lamps ran on fuels like kerosene, LPG, etc. These fuels are expensive. Another option available at the time of power failures is emergency light which is costly and hence un afford able to the common man. Object of the present invention:- It is a primary object of the present invention to provide a lamp which is very easy to operate and extremely safe. Another object of the present invention is to provide a lamp in which there are no carbon deposits. It should also be lightweight, portable and also cost effective. Description of the present invention: The present invention will now be explained in detail with help of figures 1, 2 & 3 of accompanying drawings. Figure 1 shows the front view of the present invention. Figure 2 shows the cross-sectional view of the present invention. Figure 3 shows the chimney separated from the fuel tank. -1- Figure 1 illustrates cylindrical water tank (1), lid (2), chimney (4) nipple (5). Figure 2 illustrates cylindrical water tank (1), lid (2), fuel tank (3), chimney (4), nipple (5). Figure 3 illustrates fuel tank (3), chimney (4). It should be understood that the present invention can be of any shape depending upon the requirements of the customer; hence the accompanying figures are not limiting in any respect but are merely for illustrative purpose. The following description is of an exemplary embodiment of the invention only, and is not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the following description is intended to provide a convenient illustration for implementing different embodiments of the invention. As will become apparent, various changes may be made in the function and arrangement of the elements described in this description without departing from the spirit and scope of the invention. The present invention comprises of a cylindrical water tank (1), which is covered by lid (2). At the centre of the said water tank, there is a small fuel tank (3). This fuel tank is perforated on its curved surface. A hollow chimney (4) with a nipple (5) on the top is placed over the fuel tank. The working of the present invention is as follows. Remove the clamp and separate the chimney cover. Fill water tank upto half its height. Remove the chimney and fill fuel (carbide) stones in fuel tank. Close the fuel tank air tight with the chimney. Now the lamp is ready; wait for few seconds and light the nipple of the chimney. The Carbide stone reacts with water to give acetylene gas which is combustible and gives the flame. 2 Once fully loaded, the lamp will bum for about 6-7 hrs. The nipple light is put off when not required and carbide stones are removed from the fuel tank. The carbide stones are stored only in air tight plastic bag for reuse. Advantages: The present invention is very easy to operate and extremely safe. The gas flames in the present invention are stronger, with no carbon deposits, due to which the flame does not extinguish easily in open air. It is remarkably lightweight, hence can be carried anywhere. The present invention emits light equivalent to a 15 V to 25 V electric bulb. Once fully loaded, the lamp will burn for about 6-7 hrs. If a 100 gms stone is loaded the lamp will burn about 4 hours which costs about Re. l/- per hour. Further, the present invention requires no maintenance. Hence it is much more cost effective compared to existing prior arts. 3 I CLAIM ;- 1) A lamp operating on carbide and water which comprises of a cylindrical water tank (1), which is covered by lid (2); wherein at the centre of the said water tank, there is a small fuel tank (3); wherein the said fuel tank is perforated on its curved surface; wherein a hollow chimney (4) with a nipple (5) on the top is placed over the said fuel tank; wherein said water tank is filled upto half its height with water, and fuel (carbide) stones are filled in the said fuel tank. 2) The lamp as claimed in claim 1 which comprises of a cylindrical water tank (1), which is covered by lid (2). 3) The lamp as claimed in claims 1 and 2 wherein at the centre of the said water tank, there is a small fuel tank (3). 4) The lamp as claimed in claims 1 to 3 wherein the said fuel tank is perforated on its curved surface. 5) The lamp as claimed in claims 1 to 4 wherein a hollow chimney (4) with a nipple (5) on the top is placed over the said fuel tank. 6) The lamp as claimed in claims 1 to 5 wherein said water tank (1) is filled upto half its height with water, and fuel (carbide) stones are filled in said fuel tank (3). 7) The lamp as claimed in claims 1 to 7 herein is illustrated in figure 1, figure 2 and figure 3 of accompanying drawings. D ated 12TH D ay of April 2004, ABSTRACT The present invention is a "lamp operating on carbide and water" which comprises of> A cylindrical water tank (1), which is covered by lid (2). At the centre of the said water tank, there is a small fuel tank (3). This fuel tank is perforated on its curved surface. A hollow chimney (4) with a nipple (5) on the top is placed over the fuel tank. The water tank is filled upto half its height with water, and fuel (carbide) stones are filled in the fuel tank. |
