Title: Low temperature extrusion process for quick cooking pasta products
IPC: A21C11/16
Filed: 1987-07-16
Abstract: Quick cooking pasta products are extruded in a low temperature process by advancing a partially pre-cooked mixture of pasta flour and water prepared in a preconditioner (15) along the length of a screw extruder (12) through a cooking zone (20-30), then through a venting zone (32) and a forming zone (34,36), and finally through an extrusion die (18) to yield an extruded product. The mixture has a maximum temperature of 215 DEG F. in the cooking zone in order to substantially eliminate the formation of darkened specks in the final extruded product which would otherwise represent portions of the mixture that are burned during cooking. Limiting the maximum temperature of the mixture in the extruder also greatly enhances the extruded pasta quality by increasing product resistance to overcooking and improving the retention characteristics of the original product intergrity. Venting of the gaseous products from the mixture during the time that the latter passes between the cooking zone and the forming zones removes significant amounts of moisture to enable less shear to be imposed on the mixture during the cooking process and to decrease the time required for rehydration of the extruded products. A venting device has a rotatable screw (60) for enabling gaseous materials to be discharged from the mixture while substantially preventing the escape of the mixture from the extruder barrel (32).

IPC: C09D5/44
Filed: 1987-08-15
Abstract: A method of electrodepositing a hard impact 
resistant and corrosion resistant film on the cathode 
of a unidirectional electrical system is disclosed in 
which a unidirectional electrical current is passed 
through an aqueous coating composition having a pH in 
the range of pH 4 to pH 6 comprising water having 
dispersed therein an hydroxy functional cationic 
resin comprising an adduct of a resinous polyepoxide 
having a number average molecular weight in the range 
of about 600 to about 6000 and an hydroxy value of 
from about 0.2 to about 0.4, this resinous 
polyepoxide having its molecular weight optionally 
increased by reaction with a stoichiometric 
deficiency of organic polyisocyanate, with a mixture 
of monosecondary amines in an amount to consume 
substantially all of the epoxy functionality of said 
polyepoxide in the formation of tertiary amines by 
reaction of the monosecondary amines with the oxirane 
groups of the polyepoxide. This mixture of 
monosecondary amines comprises a mixture of diethanol 
amine and dibutyl amine in molar proportions within 
the range of 1:2 to 2:1. The cationic resin is 
dispersed in the water by means of neutralization 
with a volatile organic acid to an extent of at least 
80%, and the electrical current passes through the 
cathode to deposit a resin film thereon, which is 
then usually rinsed and baked to cure the same. The 
mixture of monosecondary amines provides good bath 
stability combined with electrical deposition 
characteristics in the cathodic electrodeposition 
process.

IPC: B01D15/04
Filed: 1987-01-08
Abstract: A process for the production of dialkali metal phosphates 
by ion exchange is disclosed. The process is carried out by first 
ammoniating a water-soluble phosphate source such as phos­
phoric acid or monocalcium phosphate. The resulting ammoni­
ated phosphate solution is then contacted with a weak cation 
exchange resin in the alkali metal form to produce the dialkali 
metal phosphate as well as an ammonium-loaded weak cation 
exchange resin. The cation exchange resin is regenerated by 
contacting it with an alkali metal salt solution which effects an 
exchange of alkali metal for ammonium to produce a regener­
ated weak cation exchange resin in the alkali metal form as well 
as a water-soluble ammonium salt corresponding to the initial 
alkali metal salt. The process may be carried out in convention­
al fixed or pulsed bed ion exchange systems although it is most 
advantageously carried out in an Advanced Separation Device 
which is a multi-chambered device which enables the process 
to be carried out both continuously and with a greater degree 
of efficiency than is possible using conventional ion exchange 
systems.

Abstract: A method for producing galactooligosaccharides 
characterized by reacting lactose with an enzyme to obtain a 
sugar solution containing galactooligosaccharides expressed 
by the formula Gal-(Gal) n -Glc (wherein Gal denotes a 
galactose residue, Glc denotes a glucose residue, and n 
denotes an integer of 1 to 4), then separating the sugar 
components in the sugar solution by column chromatography 
using a strong acid cation exchange resin to collect 
fractions containing high concentrations of galactooligo­
saccharide from the eluates from the column. Therefore, 
this method can efficiently recover galactooligosaccharides 
of high purity from the sugar solution.

IPC: H01C7/00
Filed: 1985-09-12
Abstract: In an electrical device comprising first and second members having different resistivities, a thin contact layer of intermediate resistivity is provided between the first and second members. The contact layer, (which may comprise a conductive polymer) is intimately bonded to the member of highest resistivity (which may comprise a second conductive polymer) e.g., by a printing process. The member of lowest resistivity may comprise a third conductive polymer, in which case it may be intimately bonded to the intermediate contact layer, e.g., by a printing process, or it may comprise a metallic member, in which case good electrical contact may be made merely by pressing the metallic member against the contact layer even when the contact area is large and/or long, and even when the pressure is sufficiently low to permit, if necessary, relative movement of the metallic member and the contact layer without disrupting the bond between the contact layer and the resistive element. A preferred device comprises four or more members of different resistivities. The members are arranged adjacent each other in order of decreasing resistivity. The least resistive member preferably comprises a metal and the other members conductive polymer materials.

Title: Flexible membrane heat sink
IPC: H01L23/473
Filed: 1989-01-25
Abstract: An expandable and contractable sealed environment 
is provided by a rigid frame member (12) and a pair of 
deformable heat transfer elements (14,16) fixed to the 
frame member (12). The frame member is located between 
two heat-producing electronic assemblies (20,22). A 
coolant agent is pumped into the sealed environment to 
flex the membranes (14,16) and cause them to conformally 
contact the pair of electronic assemblies (20,22). 
Excess heat in the assemblies (20,22) is then allowed to 
pass across the membranes (14,16) and into the coolant 
agent for dissipation purposes. In order to remove the 
electronic assemblies (20,22), the pressure of the 
coolant agent is reduced, which permits the heat 
transfer elements (14,16) to return to their nondeformed 
states removed from the assembly. Thus, the electronic 
assemblies (20,22) can be removed without the need to 
open fluid couplings.
