Abstract: Title of the Invention DESTINATION SELECTION APPARATUS FOR A      BUS ORIENTED COMPUTER SYSTEM            Abstract of the Disclosure In order to carry out data transfer among the sub-systems of a bus oriented data processing system, each sub-system is coupled to the bus by a local bus adapter which con-trols both source and destination aspects of the information transfer.  Each local bus adapter has a unique "busy" line which may be interrogated by any local bus adapter connected to the bus.  When a source subsystem wishes to transfer information to a destination subsystem, the source local bus adapter determines from the destination local bus adapter's busy line whether or not the destination subsystem is available to accept the informa-tion.  If the destination subsystem is available, the source local bus adapter requests access to the bus from priority reso-lution apparatus.  When the source request is granted, the source local bus adapter issues the message to the bus and also sets the destination local bus adapter's busy line to designate the busy state which indicates to the destination bus adapter that it must prepare to receive a message and also indicates to all subsequently requesting local bus adapters that the particu-lar subsystem to which information just placed on the bus is to be transferred is temporarily not available to receive informa-tion from any other local bus adapter.  When the message has been received by the destination local bus adapter, both the source and destination local bus adapters enter a status cycle to check the integrity of the transmitted massage.  If the message is received intact, both the source and destination local bus adapters complete their individual housekeeping tasks during which the destination local bus adapter tuns off its busy line.  If an error has occurred during the message transmission, the destination subsystem, after the transfer has been retried once, disregards the message and turns off its busy line.

Abstract: ABSTRACT         A rechargeable metal oxide-hydrogen battery which operates on the back-to-back electrode placement theory as opposed to single metal oxide-hydrogen couple cells.  Interconnecting of electrodes in series and construction of an electrode stack of series connected electrodes is utilized in one embodiment in place of bipolar construction to achieve high voltage operation.          In a second embodiment, back-to-back construction is used for positive electrodes in a parallel arrangement of electrode connection to complete an operative cell.          Individual cells are separated by a nonporous polymer separator which avoids the formation of electrolyte films which tend to electrochemically short each cell, yet are fashioned of light weight and volume to keep sizes to minimum dimensions.  Interconnection of various cells is by means of bus bars coupled to electrode tabs.  The entire stack of cells is held under compression by end plates and one or more tie rods, or, in the case of prismatic cell design, the stack can be held under compression by the walls of the battery container.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to tubular ferromagnetic inductive elements and to a process for producing air gaps in them. Ferrites used to make ferromagnetic inductive elements are ceramics and, therefore, elements made from ferrites are hard and brittle. Their brittleness subjects them to breakage, and their hardness makes alteration of them after they are fired expensive, since grinding or carbide cutting is usually required. There is a need for an economical gapped tubular inductive element. Prior art techniques cannot economically produce such an element because of the hardness and brittleness of the material.      According to the present invention, tubular ferromagnetic elements are held in a fixture which moves them axially past a laser beam focused on the tube so that an axially elongated slot is formed in the wall by vaporization of material. Effect of the laser beam on the inner wall opposite the slot is minimized by defocusing of the beam as it passes through the bore of the tube, adjustment of the rate of movement, and/or use of a temporary filler piece in the bore. Interruption of the beam while the tubular element continues to move can produce "ties" between slots which give a mechanically stronger product.

Abstract: BIPOLAR PROTECTIVE SWITCH                 ABSTRACT OF THE DISCLOSURE           A bipolar protective switch has a two-piece housing.    An electromagnet constitutes the actuating device made either in the form of a zero voltage actuator or an excess current actuator.  The armature of the electromagnet drops in the event of a voltage failure or is attracted if an excess current appears, thus disconnecting the switch.  The switch can be turned back on again only after the voltage returns or normal current returns by the actuating device.  A rocker is disposed on the narrow upper surface between the two pieces of the housing as the actuat-ing member.  The electromagnet and connecting members are disposed on the underside of the housing, a portion of the electromagnet being located between the two pieces of the housing.  A sup-port of an insulating material, is disposed in the housing upon which support connecting members are disposed.  Two fixed contact members located side by side and two movable contacts as well as a lever which is common to the two movable contacts is swivelable, and is subject to the force of a spring, the lever being connected to the rocker by a yoke.  The lever is lockably connected with one arm      of a two-armed release lever disposed on the support,  the other arm      being effectively connected with a release rod of the electromagnet.
