Title: Fluid treatment
IPC: B01F3/04
Filed: 1985-06-21
Abstract: A carbonation method and apparatus is described in which carbonation is achieved by forcing carbon dioxide in gaseous form from an atmosphere thereof downwardly into a body of water to be carbonated. This may be achieved by a vaned rotor (3) rotatable about a horizontal axis or other means. The carbon dioxide atmosphere is preferably maintained at a pressure of about 100 psig (6.8 bars). The degree of carbonation may be varied by varying the time for which the carbonation operation is carried on. A flavour concentrate supply means, containing various flavours (46,48,50), is pressurized for the supply of the concentrate utilizing what would otherwise by waste carbon dioxide gas from the carbonation chamber after completion of the carbonation operation.

Abstract: A quick-action on/off valve comprises a housing (2) 
including a partition (10) having an interconnecting passage­
way (18,20) between two chambers (12,14) on opposite sides 
of the partition. One chamber includes a fixed piston (36,38) 
and a movable cylinder (40), the cylinder (40) including a 
resilient disc (44) between its closed end (42) and the port 
leading from the first chamber (12), and a spring (46) urging 
the cylinder (40) in the direction tending to close the latter 
port. Spacing means (48) are provided between the partition 
(10) and the open end of the cylinder (40) for continuously 
maintaining communication between the first chamber (12) 
and the interconnecting passageway (18,20). The difference 
in the cross-sectional areas of the first port and of the 
cylinder (40) result in a smaller area of the cylinder (40) being 
effective to open the valve when the valve is closed, but a 
larger area of the cylinder (40) being effective to close the 
valve when the valve is open, thereby providing a quick-­
action opening and closing of the valve.

IPC: D03D15/00
Filed: 1986-06-24
Abstract: An improved woven fabric made from unsized carbon 
fiber multifilamentary tow is provided which possesses a 
novel physical configuration that better enables it to undergo 
impregnation with a matrix-forming resin to form quality 
composite articles. The individual filaments of the tow are 
randomly decollimated and commingled with numerous fila­
ment cross-over points throughout the length of the multifi­
lamentary tow in order to create a multitude of interstices 
between adjacent filaments which are well adapted to receive 
and retain a matrix-forming resin as evidenced by the ability 
of the filaments when subjected to the flaring test described 
herein to resist lateral expansion to a width that is as much as 
one and one half times the original width. The multifilamen­
tary bundles have been found to be capable of being readily 
woven with no significant productivity loss to form a quality 
reinforcing fabric while free of a protective size.

Title: Sliding gate assembly for an exhaust brake
IPC: F02D9/06
Filed: 1986-06-04
Abstract: A slidable gate assembly is to be mounted on an exhaust brake having a housing (10) with aligned inlet and outlet apertures (13,14) to allow the passage of exhaust gas through the housing. The flow of exhaust gas is controlled by a slidable valve gate (15) forming part of the slidable gate assembly and having an exhaust gas relief passage (56) therethrough. The valve gate is mounted one end of the piston rod (21) and at that same end there is provided a closure device (60) for opening and closing the exhaust gas relief passage in the valve gate. A biasing force applied through the piston rod (21 preferably by a coil spring (61), biases the closure device (60) towards a closed condition of the exhaust gas relief passage. The piston rod (21) is movable relative to the valve gate (15) to open the exhaust gas relief passage (56) through the valve gate in dependance upon the force applied by the biasing spring (61). The closure device is forced to an open condition by the pressure of exhaust gas applied through the exhaust gas relief passage to the closure device. With this construction the biasing spring (61) can be located at a position remote from the body of the exhaust brake so as to be operable below the setting temperature of the spring.

Patent EP-0279158-A3 (EP)
IPC: G06K9/68
Filed: 1988-01-05
Abstract: A technique for recognizing hand-drawn graphic symbols 
operates on vectorized graphic data, including lines, arcs, and 
circles, that have been produced by an automatic drawing 
recognition system. The user creates segmented rule bases for 
recognizing various symbols by describing the geometric 
structures of recognizable symbols and subsymbols. The rule 
bases each are compiled into a respective decision tree. Fetched 
input vectors and entities are placed in software "blackboards", 
and more particularly, into appropriate symbol slots and 
subsymbol slots thereof. The growing symbol and subsymbols on 
the blackboards are continually restructured until they form 
closed loops or the blackboards are filled. The decision tree 
then is applied to all possible permutations of the symbols 
and/or subsymbols to accomplish partial or complete recognition. 
An inference engine subsystem controls application of the 
decision trees to limited bits of the symbols and subsymbols, 
matching decision subtree segment labels to attributes associated 
with the blackboard data, and orders the matched data according 
to degree of matching to effectuate application of the decision 
tree to the linked lists.

Title: Support material and process for its manufacture
IPC: B41N1/08
Filed: 1988-04-19
Abstract: 1. Support material and aluminium planographic printing plate, and process for its manufacture. 
<??>2.1 Previously, pure aluminium or manganese-containing alloys have been used as support material for planographic printing plates with a baked photo-layer. Such alloys have an essentially higher thermal stability than pure aluminium but during electro-chemical roughening in HCl or HNO3, dark surface colorations and different grain structures appear which have an adverse effect on the technical copying properties or their general ability to respond to roughening treatment. The object is to find a support material which has a pale uniform surface after the roughening treatment, a general ability to respond to roughening treatment and simutaneously high stability under baking conditions. 
<??>2.2 A material with a fine precipitation micro-structure (degree of dispersion D < 50 phases/ mu m<3>) is produced from an aluminium alloy containing 0.2-0.6% Fe, < 1% Mn, < 0.25% Si and Cu under adherence to particular conditions during the heating and shaping. The ratio of the dispersed phases AlMnSi:AlFe:AlMn lies between 1:1:2 and 1:1:3. Because of dissolved Fe and Mn as well as the fine precipitations, this material possesses a high thermal stability. Since the very fine Mn-containing phases are present only in small proportions, the surface quality necessary for planographic printing plates is achieved by the electro-chemical roughening in HCl as well as in HNO3. 
<??>2.3 Manufacture of aluminium planographic printing plates.
