Title: Polymerized fatty acid polyamide resin dispersions and method for the manufacture thereof
IPC: C09D11/10
Filed: 1989-02-02
Abstract: A method is provided for the preparation of stable aqueous 
dispersions of non-solvated, un-neutralized, low amine, low 
acid number polymerized fatty acid polyamide resins. In the 
preferred method of this invention, a polymerized fatty acid 
polyamide resin which has been prepared so as to have a low 
acid and low amine number is liquified by heating the 
polyamide resin to a temperature where it is at or above its 
melting point. The liquified polymerized fatty acid 
polyamide resin is then blended with a predetermined amount 
of water which is heated to a temperature such that the 
resulting blend will have a temperature above the melting 
point of the polyamide resin. A surfactant which will 
promote the emulsification of the polyamide resin and water 
is included in the mixture. The resulting mixture is then 
subjected to sufficient comminuting forces to form an 
emulsion in which droplets of the polyamide resin have a 
volume average size distribution of about 20 microns or less 
in diameter and preferably 5 microns or less. The resulting 
emulsion is then cooled to a temperature below the melting 
point of the polyamide resin causing the emulsified droplets 
of the polyamide resin to solidify as finely divided 
particles which are dispersed uniformly through the aqueous 
 
 
phase. The resulting stable aqueous dispersions of the 
polymerized fatty acid polyamide resin which are obtained 
are especially useful for hot melted adhesive applications, 
and when utilized in coatings, inks, and the like.

coating layer (3; 21). The apparatus is provided with 
a gas flow suppressing type housing (15; 35) which is 
partitioned off from the atmosphere so as to suppress 
the convection current (G) flowing, due to the rotation 
of the turn table (11; 37), toward a central portion 
of the substrate (1; 31; 51) and further toward the outer 
circumferential portion thereof along a top surface of 
the substrate (1; 31; 51) and to suppress the evaporation 
of a solvent of the coating liquid into the atmosphere. 
The nozzle (10; 34) is arranged above the inner circum­
ferential portion of the substrate (1) with its end 
portion being directed to the outer circumferential 
portion of the substrate (1; 31; 51), so that the end 
portion is inclined so as to form an angle less than 90 
degrees relative to the substrate (1; 31; 51) as viewed 
from a side of the substrate. The coating liquid 
application is carried out in a hermetically sealed atmos­
phere within a sealing chamber (15; 35).

Patent EP-0375251-A3 (EP)
IPC: G02B6/42
Filed: 1989-12-12
Abstract: Efficient coupling between an optoelectronic device (13) and an 
optical fiber (15) is obtained by using different monocrystalline elements of 
different crystallographic orientation for mounting, respectively, the fiber and the 
optoelectronic device. For example, the crystallographic orientation of an upper 
monocrystalline element (17) is chosen such that a horizontal groove (20) for 
supporting the optical fiber and a reflecting surface (19) for directing light into the 
fiber may both be made by anisotropic etching. The crystallographic orientation 
of a lower monocrystalline silicon element is chosen such that appropriate etching 
will yield a mounting surface (23) for the optoelectronic device (13) which is 
suitable for directing light from the reflecting surface (19) into the optical fiber 
(15) with maximum efficiency.  
     In one illustrative embodiment, the upper monocrystalline element 
(17) is {100} silicon, and the lower monocrystalline element (18) is {112} silicon. 
As will be explained more fully later, this permits anisotropic etching so as to 
form a  V -groove (20) that supports a horizontally-extending optic fiber, a 
reflecting surface (19) that extends at 54.74°, and a support surface (23) for the 
optoelectronic device that extends at 19.48° with respect to the horizontal. These 
relative angles provide for optimum optical coupling between the optoelectronic 
device and the optical fiber, while providing horizontal surfaces for supporting 
both electronic circuitry and the optical fiber, as is desired for secure packaging 
and integration of the package apparatus into a lightwave communications system.

Title: Tether-guided vehicle and method of controlling same
IPC: A47L5/36
Filed: 1990-03-13
Abstract: A tether-guided vehicle and method of controlling same are disclosed. 
A tether sensor indicates the angle, ϑ, of the tether with respect to the vehicle 
and the tension, T, on the tether. A contact-sensitive bumper disposed about 
at least the front periphery of the vehicle indicates the position, P, and force, 
F, of contact with an obstacle. A drive system moves the vehicle in response 
to tether angle, ϑ, and tension, T, thereby providing a "servo pull" feature. 
When the vehicle contacts an obstacle, it stops, backs up, turns and resumes 
forward motion to circumnavigate the obstacle, thereby providing an "obstacle 
avoidance" feature. The invention automatically frees a tether-guided vehicle 
from a jammed condition. It also improves the maneuverability of tether-guided 
vehicles. The servo pull and obstacle avoidance features make the vehicle 
suitable in a number of applications, such as for canister vacuums, hospital 
or factory carts, and the like. The vehicle may be tethered to another robotic 
vehicle.
