Title: Trip device for an electrical switch and an electrical switch with this trip device
Inventor: KNOBEN JOSEF H A
IPC: H01H71/32
Filed: 1990-01-02
Abstract: Abstract Trip device of the suction or pull-in armature type, having a yoke (18; 35) supporting a fixed permanent magnet (22) and a movable elongated armature (23) having a head member (25). The armature (23) and the yoke (18; 35) forming a first magnetic circuit for holding the armature (23) in a first position with the permanent magnet (22), in which first position the head member (25) protrudes outside the yoke (18; 35). For moving the armature (23) electromag-netically and/or electrothermally to a second position in which the head member (25) protrudes further outside the yoke (18; 35), the yoke (18; 35) is provided with electrothermal bimetal means (33; 37). For moving the armature  (23) to the second position independently of the polarity of an electrical current, a second magnetic circuit is provided, consisting of a further yoke and one or more magnet windings (30), or consisting of a pair of mutually magnetically separate branches (44, 45; 50, 51) magnetically con-nected in series with the first magnetic circuit, and one or more magnet  windings  (46) for  mutually  oppositely  magnetizing  the branches (44, 45; 50, 51).

Abstract: A TWO-STAGE FERROSILICON SMELTING PROCESS                      ABSTRACT           The present invention relates to a process for the production of ferrosilicon in a closed two-stage reduction furnace.  In the present invention, carbon monoxide released as a result of the smelting process, in the first stage of the furnace, is used to prereduce higher oxides of iron, for example, Fe2O3 and Fe3O4, contained in a second stage of a furnace, to iron monoxide (FeO).  The iron monoxide is then used as a feed material to the first stage of the furnace. The use of a closed furnace and a pre-reduction process results in substantial energy savings in the production of ferrosilicon alloy.

Abstract: ELECTRICALLY TUNABLE INTERFERENCE FILTERS        AND METHODS FOR THEIR USE            Abstract of the Disclosure An electrically tunable interference filter comprises a semiconductor body which has a plurality of semiconductor layers.  Each semiconductor layer comprises first and second sublayers which together define a heterojunction and first and second portions which together define a pn junction located at or closely adjacent to the heterojunction.  Electrical contacts are provided for biasing the pn junctions.  Application of a forward bias to some of the pn junctions causes injection of carriers from the second sublayers across the heterojunctions into the first sublayers to modify the refractive index of the first sublayers. Application of a reverse bias to other of the pn junctions enhances an inherent electric field at the pn junctions to modify the refractive indices of regions adjacent to the pn junctions.  The applied reverse bias also depletes carriers from regions of the first and second sublayers to modify the refractive indices of those regions.  Such refractive index modifications alter the optical filter characteristics of the plurality of layers, so the filter may be electrically tuned.    - i -
Patent CA-2024881-A1 (CA)
IPC: H04M3/00
Filed: 1990-09-07
Abstract: Disclosed is an automatic call distributing system for automatically distributing telephone calls placed over a network to agent stations connected to the network by network service interfaces.  The system includes a receiving means that is connected to the network by a network service interface and receives agent status messages and a call arrival message from the network indicating that an incoming call has been made on the network.  It also includes a routing means that is responsive to the receiving means to generate a routing signal that is provided to the network to connect the incoming call to an agent station through the network.  In this manner, the automatic call distributing system has great flexibility in locating agents, so long as they are connected to the network, and in deciding which agent an incoming  call should be routed to.  At the same time, the system employs the switching hardware of the network to actually perform the switching function, thereby avoiding costs and maintenance associated with the switching hardware.  In addition, the system permits the sytem operator to maintain control of routing and any data associated with routing by the system operator.  This leads to flexibility in monitoring and reporting agent activity for management purposes.

Abstract: ABSTRACT OF THE DISCLOSURE          A method for automatically answering a production status inquiry supplied from an external device has the following steps.  The production status inquiry is received.  Next, it is determined whether or not each item related to the production status inquiry can be delivered on a requested delivery date by comparing the requested delivery date with a minimum production period necessary for producing each item. Each item indicates a respective product.  Then, a confirmation report is generated which shows that each item can be delivered on the requested delivery date when it is determined that each item can be delivered on the requested delivery date.  Subsequently, it is determined whether or not each item which is determined not to be able to be delivered on the requested delivery date is allowed to be delivered on an extended delivery date by referring to a database storing an extension period defined for each predetermined item.  An alarm report is generated which shows that each item cannot be delivered on the requested delivery date when it is determined that delivery of at least one item cannot be extended.  On the other hand, a delivery date extension report is generated which shows that each item related to the production status inquiry can be delivered on the requested delivery date or the extended delivery date when it is determined that each item which is determined not to be able to be delivered on the requested delivery date can be delivered on the extended delivery date.

Patent CA-2048263-A1 (CA)
Inventor: KRISHNAMURTHY RAMACHANDRAN
IPC: B01J23/755
Filed: 1991-08-01
Abstract: A process for extracting helium from a feedstock containing helium at moderate levels together with trace amounts of hydrogen is disclosed. Helium is separated from the feedstock by pressure swing adsorption (PSA) and the hydrogen impurity is removed by chemisorption in a nickelbased catalytic bed. Where the feedstock contains significant amounts of nitrogen, less than 5% methane, and less than 1000 ppm carbon dioxide, the catalytic step preferably precedes the PSA step. Regeneration of the catalytic bed is preferred by passing over the spent bed an inert gas with controlled amounts of an oxidizing agent, preferably oxygen, to react with adsorbed hydrogen to form water. This method substantially increases the catalyst's capacity to adsorb hydrogen when the catalytic unit is placed back in service and eliminates the conventional step of thermally regenerating the bed by heating with an inert gas for an extended period of time.

IPC: C12N15/70
Filed: 1991-09-13
Abstract: ABSTRACT            Disclosed is a method by which expression of any gene in an intact, unfused form can be achieved. The gene to be expressed is amplified using Polymerase Chain Reaction (PCR) starting from the second codon of the particular gene and the resulting product is ligated to the ATG codon which is provided by the Ncol site of the expression vector. This results in the expression of the gene in an intact, unfused form with no extra amino acids. Using this strategy high level expression of Plasmodium falciparum hypoxanthine guanine phosphoribosyl transferase (Pf HGPRT) gene, in E.coli, has been achieved.
