Trouble Light Apparatus

View page
US Patent:
59612070, Oct 5, 1999
Filed:
Jun 16, 1997
Appl. No.:
8/876854
Inventors:
Peter M. Petkovic - Chicago IL
International Classification:
H01R 3302
US Classification:
362376
Abstract:
A trouble light apparatus including a cage in which low voltage (e. g. 12 volt) light(s) are housed, a handle connected to the cage which manual switches are mounted and in which a transformer is secured is disclosed. The handle has a primary cord running from it to a plug that may be fitted into a mating plug. Additionally, a number of secondary cord and mating plugs are provided, one of which can be received in a 12-volt dc cigarette lighter socket, another of which can be received into the conventional ac power (e. g. 120/240 volt ac) receptacle and another of which may have alligator clips for attachment to a battery (e. g. 12 volt automobile battery). The secondary cords contain two electrical lines and the primary cord has three lines. The plugs allow connection to two of the three lines with different pairs of lines connected for the high voltage ac source and the low voltage source. The primary cord pairs from the high voltage ac source and is coupled to the input of the transformer and whose output is connected to the lamp sockets when the switches are operated to select that arrangement.

Electrical Braking And Energy Storage For Moving Vehicles

US Patent:
60377283, Mar 14, 2000
Filed:
Mar 29, 1999
Appl. No.:
9/280317
Inventors:
Peter M. Petkovic - Chicago IL
International Classification:
H02P 504
H02P 520
US Classification:
318364
Abstract:
A system for electrical braking and the storage for reuse of the braking energy is disclosed using alternating current (AC) rather than direct current (DC) generators coupled to the wheels of the vehicle to be braked. Upon braking, the AC generators feed the primary coil of a transformer whose secondary coil can be tapped at one of a number of different turns. Means are provided for changing the tap points so as to increase the number of turns in the secondary as the speed of the braked wheel declines. The output from the secondary is fed to a rectifier and thereafter the direct current is fed to a battery energy storage device. By increasing the turns of the secondary as the wheel speed drops, more energy can be fed and stored in the battery and the range of effective braking by the alternating current generator can be extended to lower speeds.
