Title: Device for absorbing the energy of floating bodies  approaching the coast wall
Inventor: SAWARAGI TORU
IPC: E02B3/06

Granted: 1987-09-29
Abstract: ABSTRACT OF DISCLOSURE           This invention describes a scheme for absorbing the energy of floating bodies such as ships approaching the coastal wall by providing the coastal wall with fenders made of spring materials along with dash-pots that absorb the energy of the approaching floating body due to liquid resistance so that the energy is first absorbed by the springs of the fender in the form of displacement energy and is then dissipated by the dash-pots.          According to this invention, the energy of the approaching body that is to be absorbed by the fender increases as the spring constant of the fender is made small in the conventional devices consisting of only fenders, whereas the device of this invention permits the lowering of the energy to be absorbed by the fenders without having to increase the spring constant whereby the maximum reactive force on the coastal walls is decreased and also the movement of the floating body moored in an asymmetrical mooring system can be decreased because the spring constant of the fender can be flexibly altered so as to become close to the spring constant of the mooring system.

Abstract: CANTILEVERED SUSPENSION SLING              ABSTRACT OF THE DISCLOSURE          An arm sling includes a semi-rigid trough which partially encircles and supports a patient's forearm, wrist, and hand.  A yoke is connected to the sides of the trough at a location away from the distal end.  An adjustable-length strap extends upward from the yoke over the front of the patient's ipsilateral shoulder, diagonally across the patient's back, and transversely across the front of the patient's body to an attachment point on the trough near the patient's elbow.  An elbow piece adjustably fixed to the trough accommodates various elbow angles and arm widths.  The yoke supports the patient's forearm, wrist, and hand in a cantilevered fashion at various elevations, while not interfering appreciably with lateral movement of the distal end of the trough and rotation of the patient's upper arm at the shoulder joint.

Abstract: ABSTRACT     An HIPR (high internal phase ratio) emulsion of oil in water is prepared by directly mixing 70 to 98% by volume of a viscous  oil  having  a  viscosity  in  the  range  200  to 250,000 mPa.s at the mixing temperature with 30 to 2% by volume of an aqueous solution of an emulsifying surfactant or an alkali, percentages being expressed as percentages by volume of the total mixture.  Mixing is effected under low shear rate in the range 10 to 1,000 reciprocal seconds in such manner that an emulsion is formed comprising highly distorted oil droplets having mean droplet diameters in the range 2 to 50 micron separated by thin interfacial films.   The emulsions are much less viscous than the oils from which they are prepared and may, optionally after dilution, be pumped through a pipeline.   Viscous crude oils may be transported by this method.

Abstract: LIQUID TEA MIX CONCENTRATE     Abstract of the Disclosure The present invention comprises a liquid tea mix concen-trate. The liquid tea mix concentrate is shelf-stable and substantially free of sulfur. It is characterized by a low pH, low water activity, high total solids, reduced levels of theaflavin and thearubigin, and a polyphenolic profile and molecular weight distribution distinct from other liquid tea mix concentrates. Tea beverage prepared from the concentrate is storage-stable in flavor and clarity. Acid-catalyzed degradation reactions that normally occur between tea mix components causing the development of off-flavor and malodorous sulfurous compounds and precipitates are accelerated during processing. By removing the resultant compounds, the development of off-flavors, off-aromas, and precipitates in the liquid tea concentrate is prevented without the use of preservatives.

Abstract: ABSTRACT OF THE DISCLOSURE      The  invention  relates  to  a  method  for  recovering  the valuable  metal  content  of  a  mix  of  contaminated  copper raw materials,  of which materials at least one is sulphide bearing, and which  contain  one  or more  impurities  forming  the  group arsenic,  antimony,  bismuth,  mercury,  tin,  chlorine  and  other halogens.    The  invention is  characterized  by  adjusting  the halogen content of the mix so that it is substantially at least stoichiometric in relation to remaining impurities in the group, whereafter the mix is charged to a furnace in which melting can take place and in which the mix is heated to at least 500 C, but beneath the melting points of respective ingredients of the mix, while maintaining good contact with hot gas therewith to expel substantially all of the aforementioned impurities present.   The mix is then heated to completely smelt the ingredients present, to form a slag and a copper matte,  which latter contains the valuable metal content, whereafter this valuable metal content is recovered with the air of a suitable,  conventional method.   At least  one  of  the  copper  raw materials  present  in  the  mix comprises  suitably a halogen-bearing valuable-metal  containing product, for example chlorine-bearing ash or slag.

In order to reduce crosstalk noise during motion adaptive picture processing of the color television signal with increased resolution, the following measures are taken:  the offset modulation or offset sampling frequency is reduced; additional signals to increase resolution are limited in bandwidth at the transmit-ter; the chromaticity spectrum is obtained at the transmitter from a full frame sequence of the picture and is bandwidth limited at the transmitter in the direction of vertical spatial frequencies; the luminance signal and the additional signals are complementarily filtered at the receiver; and finally, at the receiver, the chromaticity spectrum is obtained from a full frame of the transmitted color television signal.

Abstract: Abstract of the Disclosure A security system arrangement utilizing a standard PBX for monitoring a plurality of concurrently administrable guard tours.  The PBX comprises a control processor which includes a main memory containing a number of feature processing algorithms.  One such feature processing algorithm is the security monitoring algorithm.  This algorithm monitors the activities of tour guards as the guards progress through the tours.  In particular, a programmable memory defines a plurality of tours.  Each tour comprises a finite list of sequentially defined checkpoints where each checkpoint is a designated conventional station set of the PBX. A security controller activates the security system by "dialing" the appropriate feature code at a central control facility, such as an attendant console. The security controller then selects one or more of the available tours by "dialing" a tour code.  Following the selection and activation of a tour, a tour guard "dials" a check-in code at each checkpoint and progresses sequentially through the checkpoints contained in the list comprising the selected tour or tours.  The tour guard has an allotted amount of time in which to reach each of the designated checkpoints included in the tour sequence.  The tour is successfully concluded when the tour guard sequentially checks-in within the allotted time at each of the designated checkpoints included in a tour.  However, if the proper check-in sequence is not followed or if the allotted time period elapses before the tour guard reaches the next checkpoint in the sequence, the control processor detects these conditions and generates an alarm to indicate that the tour sequence is disrupted.  This alarm signals a condition that requires investigation.
