Abstract: A novel electrolytic cell produces a mixture of highly ionized hydrogen and oxygen gases by a method combining electrolysis and radiolysis of an aqueous electrolyte. The electrolyte, which may be a 25% of potassium hydroxide, is introduced into the cell and is simultaneously subjected to an electrolysing current and intense irradiation by electromagnetic radiation of frequency less than 10.sup.-10 meters.

Abstract: A catch mechanism for installation in a door frame to cooperate with a door lock on a fire door. The mechanism includes a catch member pivotable between an operative position in which to serve as a door catch and an inoperative position to enable release of the door no matter what the condition of the door lock. The mechanism includes a heat responsive locking device which locks the catch member in its catch position in the event of a fire generating high temperatures. The locking device may comprise a biased locking plunger mounted in a cavity within the catch member and normally held in a retracted position by a heat fusible metal plug but extendible on melting of the plug to engage the catch body and so lock the catch member.

Abstract: A hanger for a bicycle reflector so as to maintain the reflective face of the reflector in a generally vertical position and which includes means that prevent the reflector from being incorrectly mounted on the bicycle.

Abstract: A fuel supply apparatus generates hydrogen and oxygen by electrolysis of water. There is provided an electrolytic cell which has a circular anode surrounded by a cathode with a porous membrane therebetween. The anode is fluted and the cathode is slotted to provide anode and cathode areas of substantially equal surface area. A pulsed electrical current is provided between the anode and cathode for efficient generation of hydrogen and oxygen. The electrolytic cell is equipped with a float, which detects the level of electrolyte within the cell, and water is added to the cell as needed to replace the water lost through the electrolysis process.The hydrogen and oxygen are collected in chambers which are an integral part of the electrolytic cell, and these two gases are supplied to a mixing chamber where they are mixed in the ratio of two parts hydrogen to one part oxygen. This mixture of hydrogen and oxygen flows to another mixing chamber wherein it is mixed with air from the atmosphere.

Abstract: A novel electrolytic cell performs an electrolysis process at improved efficiencies by supplying a pulsed DC current to the electrodes thereof. In preferred embodiment a generally cylindrical anode with a fluted outer surface is surrounded by a segmented cathode having an active area equal to the active area of the anode. An electrolyte, which may be a 25 percent solution of potassium hydroxide is introduced into the cell for production of hydrogen and oxygen at the cathode and anode respectively. The current for carrying on the electrolysis process is provided by a transformer which is preferably located within an oil filled chamber inside the anode. Heat from this transformer and a magnetic field also created thereby both have a beneficial effect upon the reaction rates. The pulsing of the electrode current may in one embodiment be carried out at a rate of between 5,000 and 40,000 pulses per minute, with a rate of about 10,000 pulses per minute being preferred.

Abstract: Magnetic identification apparatus is disclosed in which a magnetically coded instrument such as a key or card is inserted into a reader which reads the recorded code. The code is recorded by disposition of discrete magnets in the instrument as the instrument is inserted into the reader, the movement of the discrete magnets relative to sensor elements in the reader causes the sensor elements to be energized. The energization of certain sensor elements is an indication of the recorded code.
