Title: Artificial seafood bait and method of making the same
Inventor: BURRESON JAY B
IPC: A01K85/00
Filed: 1989-11-20
Abstract: ABSTRACT OF THE DISCLOSURE    An  artificially  extended  natural  seafood bait is produced by dissolving gelatin  or pectin or combinations thereof  in  water  at  a   temperature   elevated   only sufficiently   to   liquify  the  material.    Into  this liquified  material  there  is  dispersed  a  quantity of natural fish or seafood ground to a particle size of  not more  than  about  1/8  inch.   Also contained within the liquified material is a mat of randomly crossed fibers of a fibrous  material  preferably  garnetted  cotton.  The foregoing fluid mass is allowed to cool to a  temperature sufficient  to  solidify  it, after which the solidified, fiber-reinforced artificially  extended  natural  bait is cut to desired bait size pieces.  In a  preferred  method of  manufacture, a quantity of the ground fish or seafood is distributed over the  surface  of a container, a layer of the fibrous mat is placed over the ground material and a second quantity of the ground material  is distributed over the  fibrous  mat.    The  liquified gelatin and/or pectin then is poured over the assembled materials in the container to penetrate  the  mass,  after which the fluid mass is cooled to  solidify  it  and  thereafter  cut  to desired bait size pieces.

Title: High-speed mesh connected local area network
Inventor: SCHROEDER MICHAEL D
IPC: H04L12/56
Filed: 1990-03-06
Abstract: ABSTRACT            A mesh connected local  area network provides automatic packet switching and routing between host computers coupled to  the  network.    The  network  has  a  multiplicity  of cut-through,  nonblocking  switches,  each  capable  of simultaneously routing a multiplicity of data packets.  Low host-to-host  latency  is achieved  through  the  use  of cut-through switches with separate  internal buffers for each packet being routed.  The switches are interconnected with one another and are coupled to the host computers of the network by point to point full duplex links.   While each switch can be coupled to ten or more network members, i.e., switches and hosts, each link is coupled  to only two network  members  and  is dedicated  to  carrying signals therebetween.  Whenever a new switch or link is added to the network,  and whenever a switch or link fails,  the switches  in  the  network  automatically  reconfigure  the network by recomputing the set of legal paths through the network.

Title: Tubular or annular elastic urinary catheter cover sleeve having germicidal activity
Inventor: BRENNER OTTO
IPC: A61L29/16
Filed: 1990-05-22
Abstract: ABSTRACT   A tubular or annular elastic cover sleeve made of an elastomeric silicone polyurethane material provided with germicidal properties is mounted onto a urinary catheter, and is prevented from movement thereon by being mounted under radial tension onto the catheter mantle.  The cover sleeve has a high tension and tear resistance and a wall thickness of .1 mm.  The cover sleeve is 2 to 10 cm in length and may be composed of a number of cover sleeve sub-units which are individually mounted on the catheter.  The cover sleeve provides a urinary catheter with a finish having a wide-range germicidal activity.  The cover sleeve may be produced by a process which includes only a small number of processing steps and requires only small amounts of germicidal material, thus lowering manufacturing cost.  The cover sleeve is universally applicable to all sizes and shapes of urinary catheters.

Patent CA-2020353-A1 (CA)
Title: Fuel supply control method and ultrasonic atomizer
Inventor: TSURUTANI KAZUSHI
IPC: F02D41/06
Filed: 1990-07-03
Abstract: ABSTRACT    Fuel supply in an ultrasonic atomizer is conducted according to a fuel increment ratio pattern in which the increment of fuel in fuel increment control for starting and warming up is 70% or less of that in a typical conventional pressure injection valve system, thereby improving startability, accelerability and fuel consumption rate and further enabling a reduction in exhaust emissions.    When the engine is started in low-temperature conditions, the fuel is supplied by continuous injection to make uniform and reduce the mean diameter of droplets of atomized fuel, thereby improving the ignitability and startability.    The fuel injection start timing is varied in accordance with the combustion chamber temperature at the time of starting the engine, i.e., when the engine is to be started in low-temperature conditions, no fuel is injected until a predetermined time has elapsed, and the fuel injection is started after the combustion chamber temperature has been raised by means of compression heat by driving the starter, thereby improving the cold startability even in the case of a fuel with a relatively high flash point.    When the engine is in a transient operating condition, fuel injection from the ultrasonic atomizer is executed immediately before the velocity of an air stream in the vicinity of the ultrasonic atomizer rises, whereby the fuel that is atomized with a sufficient spread in the intake pipe can be carried in this state by the air stream to the combustion chamber where it is burned.    Also disclosed is an ultrasonic atomizer which comprises a vibrator horn having at the distal end a slant portion and a reduced-diameter portion with a smaller diameter than that of the slant portion, and a sleeve which is disposed around the outer periphery of the vibrator horn to feed the fuel over the entire circumference of the vibrator horn, the sleeve having an opening which faces the slant portion, whereby the fuel can be smoothly atomized by ultrasonic vibrations and sprayed with a predetermined spray angle.

Title: Method for calendering a paper or cardboard web coated at both sides
IPC: D21G1/00
Filed: 1991-04-08
Abstract: To achieve desired treatment results at both sides of a material web to be calendered, the material web is initially guided through a first nip formed between yieldable elastic surfaces confronting the throughpassing material web.   In the first nip there is predominantly applied a relatively high pressure to the material web.  Then the material web is guided through  a  successively  arranged  second  nip  formed  between practically  non-yieldable  hard  surfaces  confronting  the throughpassing material web.  In the second nip there is applied, apart from pressure, in particular heat to the material web.  The treatment result achieved in the first nip, namely the smoothness and glaze values of the treated material web, are augmented at both sides of the material web to achieve desired treatment effects.

Title: Method for improving thickeners for aqueous systems
Inventor: EISENHART ERIC K
IPC: C09D7/12
Filed: 1991-05-27
Abstract: A method is provided for improving thickeners used in aqueous system. The improvement is directed to the elimination of organic cosolvents which are conventionally added to aqueous solutions of certain hydrophobic thickeners. This method involves the reversible complexation of cyclodextrin compounds with hydrophobia moieties on the thickener molecule to suppress the viscosity of the aqueous solution containing the thickener so that such the solution can be easily handled. This is followed by decomplexing the cyclodextrin from the thickener to permit the thickener to perform its intended function.
