Abstract: In known circuit breakers for fault current protection, a great deal of space is taken up by the arrangement of the switching contacts on the base plate and their operation by means of a switching slide provided with bridging contacts. The transmission elements of the switchgear required for operating the switching slide result in an increased force being required to release the switch lock, because of the friction forces occurring in this case. By means of the design with contacts 36, 37 arranged side-by-side, the space requirement for the circuit breaker for fault current protection is reduced. A newly designed switchgear with a support 14 on the latching lever 10 for a supporting lever 12 reduces the forces required for release; in addition, a switching cam 47 prevents overloading of the test current circuit provided for testing the release function. The new type of circuit breaker for fault current protection is advantageously suitable for use in domestic meter installations. <IMAGE>

Abstract: A process for the recovery of halogenated hydrocarbons from a gas stream comprises passing the gas stream through a bed of hydrophobic molecular sieve adsorbent, preferably of the high silica zeolite type. Such adsorbent has pore diameters large enough to permit molecules of the halogenated hydrocarbons to pass therethrough and be selectively adsorbed in the large internal cavities of the crystal framework, whereby the halogenated hydrocarbons are removed. The gas is continued to be passed through the bed of adsorbent material until the material is saturated to the extent that breakthrough of the hydrocarbons is determined. The adsorbent material with adsorb phase of halogenated hydrocarbons is removed from the machine and regenerated by exposing the saturated material to an inert purging gas stream under conditions which desorb the halogenated hydrocarbons from the adsorbent material into the purging gas stream. The halogenated hydrocarbons are then removed from the purging gas stream and purified to a purity for reuse of the recovered halogenated hydrocarbons.

Vapors formed in the chamber generated may be evacuated by a vacuum applied to an inner tube (24). Fluid flow regulates catalytic thermal tip temperature which may be monitored by a thermocouple (42) positioned within the chamber. Vacuum and gas flow may be controlled by an automatic or manual controller (46) which is in direct communication with the temperature monitor (48).

Abstract: A contention mechanism is disclosed for a communication network that provides perfect scheduling to avoid collisions between packets from a cluster (10) of M circuit boards (11) connected to a communications bus (20,23). The contention mechanism (19) includes a 2-phase contention procedure comprising a first phase priority contention phase (50), where boards with a highest priority and a real data packet to transmit proceed into a second contention phase (51), where a pointer is used to declare one of the remaining priority phase circuit boards as the overall winner to transmit its packet during a subsequent packet period. When no circuit board has a packet to transmit, all M circuit boards are declared as winners of the first priority phase, and a board is declared the winner on a distributed basis to transmit a "dead-space" packet over the bus (20). The real and dead-space packets can also be encoded and/or include a parity bit (56) to ensure signal transitions sufficient to maintain a duty cycle required by A-C coupled devices connected in the network and also provide fault isolation.

Abstract: In a method of applying a voltage pulse for injecting/extracting electrons into/from a non-volatile semiconductor memory in which high and low levels of a threshold voltage corresponding to presence and absence of storage of electrons are caused to correspond to binary information, the method includes the steps of generating a plurality of voltage pulses each having an ability of injecting or extracting only a portion of all electrons to be stored, and applying the plurality of voltage pulses to the non-volatile semiconductor memory to thereby carry out injection/extraction of all the electrons. 
     Since the pulse of a Fowler-Nordheim current flowing through the tunnel insulating film by one voltage pulse is short, the density of holes produced in the tunnel insulating film by such a current pulse is extremely low. As a result, the number of holes trapped by a plurality of Fowler-Nordheim current pulses caused to flow by a plurality of voltage pulses is reduced, so the life time of the tunnel insulating film is prolonged.

Abstract: In a boiling water reactor (R) for a nuclear power plant, provision is made to sample the core bypass region immediate the top guide (12) to determine the physical and chemical constituents of the moderating water. A conduit (50) for a local power range monitor is fitted with a measurement assembly (54). The conduit and measurement assembly are inserted up to the vicinity of the top guide (12). A tube (54) opening (60) is provided to the bypass region immediate the top guide. During reactor operation, the saturated liquid in this region is flashed (54,74, W drain) to a steam water mixture (18% steam) at constant enthalpy and is rapidly removed from the reactor to measuring equipment in the reactor building, the removal interval being in the range of 4/10ths to 7/10ths of a second. During removal, the radiolytic disassociated gases (namely hydrogen and oxygen) partition to the steam phase where their recombination is retarded and accurate measurement of their constituent content can be made. Also, temperature of the steam water mixture decreases thereby preserving unstable species like hydrogen peroxide that degrade much more rapidly at high temperatures. In the reactor building, the gases are further cooled, condensed and divided with a first stream being diverted and cooled for detailed chemical analysis (84) and a second stream reheated and pressurized for measurement of electrochemical potential (90). A substantially real time measurement of the chemical state of the reactor to enable monitoring, measurement, and correction of harmful imbalance is provided.
