Abstract: HOLLOW CORE CONCRETE BUILDING PANEL      ABSTRACT:   The present invention provides a highly flexible building panel design and low cost manufacturing process that enables the connection of two separately finished skins (12A & 12B) with a solid cementitious bond (14 & 16) while creating a hollow core area (18) between said skins.  The lightweight panel (10) contains internal formwork (15) for the structural columns (33) and beam (34) which are cast in situ after said panel has been placed.  In addition, said hollow core area may be left hollow, partially filled or totally filled with various types of insulating materials as may be desired for a particular application.  Due to the high quality finish of both skins, the panel offers significant cost savings in each of its numerous applications.  Furthermore, because of the flexibility of the hollow core area, the panel may be customized for different structural or insulating applications.  The panel may be used for structural or non structural purposes, for wall, floor and roof panels and for non-building purposes such as noise barriers, fence walls and retaining walls.

Abstract: A programmable controller has a rack that houses and electrically connects a number of I/O modules and a processor module. The processor module includes a external communication network interface, a system memory, a processor section which executes a user-defined control program and a I/O interface that handles the exchange of data with the other modules. The I/O interface has circuitry for pre-processing data from defined input modules, thereby relieving the processing section of certain tasks, The shared memory contains information defining the input module from which to obtain data for pre-processing and the bits of that data to be examined for specified logic level transitions. The stored information also designates the frequency at which the data is to be read from the defined input module and how many occurrences of the specified logic level transitions must take place before the I/O interface signals the processor section that the pre-processing is complete.

Title: Production of acid soluble titania
Inventor: O'BRIEN BRIAN ANTHONY
IPC: C01G23/047
Filed: 1990-05-10
Abstract: The specification discloses a method of making acid digestible titania. The method comprises the steps of: (1) adding a magnesium or manganese compound to a titaniferous mineral if the content of manganese and magnesium in the mineral is insufficient; (2) heating the mineral in the presence of a reductant for a sufficient length of time and at a sufficiently high temperature to permit the seduction of iron containing compounds to metallic iron and enable titania present to convert to an acid digestible form; (3) cooling the mineral; and (4) separating iron from the mineral by means of an aqueous aeration step. The titaniferous mineral contains insufficient magnesium and manganese if the following expression is not satisfied: 1.98a + 1.14b/d > 0.08 where a represents the percentage by weight of MgO contained in the mineral, (b) represents the percentage by weight of MnO contained in the mineral; and (d) represents the percentage by weight of TiO2 contained in the mineral. The magnesium or manganese compound is either an oxide or a compound that is capable of converting to an oxide under reaction conditions.  An aqueous aeration technique described in the specification involves the use of a sequesterant that is capable of sequestering iron from the mineral without significantly lowering the local pH while at the same time permitting the formation of an oxide of iron at a point away from the mineral. An example of such a sequesterant is citric acid.

IPC: G01H17/00
Filed: 1992-01-29
Abstract: A system and method are provided for monitoring synchronous blade vibration in a turbo-machine. At least three sensors capable of detecting the arrival of each blade are arranged about the cylinder which surrounds the tips of the blades. The location of the sensors is selected to minimize the influence of errors in the data. To this end, and to simplify the installation of the sensors into the cylinder, the sensors may be non-uniformly spaced. The location of each sensor for purposes of constructing Fourier transforms is determined using the arrival times at the blades at peach sensor, expressed as a fraction of a rotor revolution.      The transform matrix is constructed for a predetermined discrete set of M harmonics, so that M harmonics are analyzed simultaneously, the number of harmonics which can be simultaneously analyzed is related to the number of sensors used. The blade arrival time data at each sensor, expressed as a fraction of a rotor revolution, is analyzed to determine the amplitude of the blade vibration at each of the harmonics selected for the set. The calculations are repeated for a variety of harmonic sets in order to accurately interpret the results in the event there is significant vibration at harmonics not included in the initial set.

Abstract: KAYAK RIGHTING METHOD AND APPARATUS The present invention provides a method and an apparatus for reducing the skill required of a paddler to right a capsized kayak without exiting it, and to thus avoid the dangers associated with exiting a kayak after capsize. In broad terms, the paddler is provided with a simple and rapid means of creating a buoyant force to one side of the capsized kayak, which can be used to produce a generous amount of torque for righting. More specifically, an inflatable flotation device is held in place on the deck of the kayak and is provided with a handle. Upon capsize the paddler grasps and pulls the handle, whereupon the flotation element is released from its securing container and automatically inflated from compressed gas cartridges. The paddler can then lean on the handle and attached flotation element to right the kayak without exiting it.

Title: Multiple-stator induction synchronous motor
Inventor: SATAKE TOSHIHIKO
IPC: H02K19/12
Filed: 1990-10-24
Abstract: An induction synchronous motor comprises: a unitary rotor having a first and a second rotor core; a first and a second stator mounted surroundingly facing the first and the second rotor core; a voltage phase shifting means for producing a first and a second phase difference; a static magnetic field around each of the first and second rotor cores; and a rotor magnetizing means having diodes for rectifying alternating voltages and for having the resultant direct current produce magnetic poles in the first and second rotor cores. The motor initiates its operation as an induction motor based on the first phase difference produced by the voltage phase shifting means. The first phase difference is shifted to the second phase difference produced by the phase shifting means, and the first and second rotor cores produce magnetic poles which are attracted by the rotating magnetic field produced by the first and second stators, resulting in the synchronous operation of the motor.
