Title: Branched hydroxy-terminated aliphatic polyethers
Inventor: AHAD ELIE
IPC: C08G65/24
Filed: 1988-07-04
Granted: 1992-05-05
Abstract: ABSTRACT         The invention disclosed is a process for the preparation of branched hydroxy -terminated aliphatic polyethers having alkyl azide substituents, having a structural formula   G = GAP unit   n1 = number of GAP units in segment 1 n2 = number of GAP units in segment 2 ns = number of GAP units in segment s s  = total number of segments in the molecule n  = total degree of polymerization (total number of GAP units) n  = (n1 + n2 + n3 + n4 ...... + ns) =   5 ?  n  ? 400, and a molecular weight of about 500 to 40,000, and a process for the preparation thereof which comprises the single step of reacting a solid rubbery polyepichlorohydrin (PECH) of molecular weight of about 0.5-5.0 x 106 with epichlorohydrin monomer (ECH) and an ionic azide selected from the group consisting of sodium azide, lithium azide and potassium azide, in a suitable organic solvent at elevated temperature, while agitating.  According to a further aspect of the invention, the molecular weight of the polyether product may be controlled by adjusting the weight ratio of ECH:PECH, while maintaining a weight ratio of ionic azide:      (ECH + PECH) of about 1:1.

Title: Metal-making apparatus involving the smelting reduction of metallic oxides
Inventor: MAEDA TAKUYA
IPC: C21B13/14
Filed: 1988-11-10
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE A metal-making apparatus is disclosed as adapted for the production of molten iron from iron ore which is  in a state of particles with a wide range in size. Included are a solid-state prereduction furnace for preliminarily reducing  the raw ore particles in a solid state, and  a smelting  reduction furnace for smelting the  prereduced ore particles and reducing them in a molten state.  High temperature  reducing gas generated within the  smelting reduction  furnace  is directed  into  the  prereduction furnace  and  blown up through a  distributor  on  which there is loaded a charge of the raw ore particles.   The ore particles of larger size form a fluidized bed on the distributor  and  so are prereduced by  making  intimate contact with the gas.  Ore particles of smaller size, on the other hand, are carried away from the fluidized  bed by  the  waste gas and thereby  prereduced  while  being recirculated    through   the   prereduction    furnace. Discharged from the prereduction furnace, the prereduced ore  particles of larger size are recharged  by gravity into the smelting reduction furnace.  The prereduced ore particles  of smaller size are recovered from the  waste gas   and  pneumatically  injected  into  the   smelting reduction furnace.

Title: Interprocessor switching network
Inventor: READ EDGAR L
IPC: H04L12/56
Filed: 1988-11-10
Granted: 1992-11-10
Abstract: ABSTRACT OF THE DISCLOSURE          A message transport network is provided for high speed switching between processing elements.  Clusters of low speed processing elements may be connected to the message transport network through a transport node controller.  The transport node controller and the high speed processors are connected to the gateways.  A pair of gateways may be connected through a transport interchange node to allow communication between processors associated with the gateways. A transport interchange supervisor maintains a record of the status of each gateway and generates commands to form connection between gateways in the transport interchange node. A maintenance controller and system maintenance processor oversee the validity of the data being passed through the system on paths independent of the data transfer paths.  The message transport network may be used in a variety of applications, such as a telephony switch, a signaling transfer point system or a fault tolerant minicomputer.

Title: Resonantly driven earth mover
Inventor: GURRIES RAYMOND A
IPC: E02F3/815

Granted: 1992-11-24
Abstract: RESONANTLY DRIVEN EARTH MOVER                 ABSTRACT OF THE DISCLOSURE         An improved version of applicant's prior bulldozer mold board assemblies is disclosed.  Such prior assemblies include a mold board, a reciprocating cutter blade along the lower edge of the mold board, and a resonant beam mounted aft of the mold board.  The vibration of the beam results in a reciprocating force at the node, which is undesirable in applicant's prior device.  The present invention improves on applicant's former construction by pivotably supporting the mold board so that the mold board is pivotable about a transverse axis.  The resonant beam is connected at its central node to the mold board.  In this fashion, the reciprocating transverse forces on the node of the resonant beam are transmitted to the pivotably mounted mold board to agitate the material in contact therewith.

Abstract: ABSTRACT                 SCREW/CAP ASSEMBLIES AND THEIR MANUFACTURE      It is known for coloured plastics caps to be pushed by  a  customer  onto heads  of metal  screws,  after  the screws have been secured to sheets of coloured cladding or roofing.  It is also known for the caps to be moulded around the screw heads by a manufacturer.  In the present invention, a screw/cap assembly is formed by sticking an initially separate cap onto the head of a screw by an adhesive, such as an epoxy resin sufficiently strong to allow the screw to be driven while the cap is in place. The intention is that the manufacturer would keep stocks of the caps and stocks of the screws of different types, and  only  stick  chosen  caps  onto the heads of  chosen screws in response to specific orders from customers.

Granted: 1994-10-11
Abstract: ABSTRACT OF THE DISCLOSURE            A process is disclosed for dry beading carbon black, with which the quality of the beads can be purposefully influenced and an increase of the throughput of a particular beading apparatus can be achieved.  The process foresees that material that is to be beaded is preconsolidated by vacuum prior to or during the beading process.  An apparatus for carrying out the single-stage version of the process consists of a beading drum in which filter surfaces that are affected by a vacuum are arranged parallel to the on-going beading process so as to preconsolidate the starting material that is in powder form.  In one apparatus, the inner casing of the drum is configured as a filter surface; in the other, bundles of fixed filter tube are installed in the lower chamber of the drum.
