Patent EP-0251184-A3 (EP)
IPC: C01F7/02
Filed: 1987-06-24
Abstract: This invention relates to the preparation of small sphero­
idal solid agglomerates. More particularly, the process prod­
uces strong solid speroidal agglomerates containing alumina 
or a mixture of alumina and at least one other inorganic mat­
erial, which process comprises:  
     (a) mixing at high speed a portion of alumina or a mixture 
of alumina and at least one other inorganic material in the 
form of hydrophilic micron-sized particles in a water-­
immiscible liquid thereby forming a dispersion;  
     (b) gradually adding to the dispersion an aqueous acidic 
phase while continuing the high-speed mixing until substan­
tially spherical micro-agglomerates form within the water-­
immiscible liquid;  
     (c) subjecting the micro-agglomerates to agitation in a 
vessel having a hydrophobic inner surface at a speed low 
enough to achieve substantially uniformly sized speroidal 
agglomerates;  
     (d) drying the agglomerates to produce hardened spher­
oidal uniformly sized agglomerates; and  
     (e) optionally further separating the agglomerates by 
size. Optionally, the aqueous phase in step (b) may include 
the soluble salts of catalytic metals, and bases and/or col­
loidal-sized inorganic particles. These spheroidal particles 
can have either smooth surfaces or polylobe surfaces dep­
ending on the conditions of preparation. They have dia­
meters generally between 1 to 5 mm and are useful as cata­
lysts, or catalyst supports. Catalytic components may 
subsequently be deposited on the support.

Title: Flat sheet die for the extrusion of thermoplastics
IPC: B29C48/31
Filed: 1987-06-24
Abstract: An extrusion die having an adjustable lip opening through which thermoplastic material is forced to form a flat sheet. Fine adjustment of the lip is effected thermally and without play by the provision of an element or a heating or cooling block which braces the lip. Coarse adjustment is effected manually, and without play, by operation of a pair of bolts. One bolt axially shifts the block, and the other bolt tightens the block against the die body.

Abstract: A composition suitable for topical application to 
mammalian skin or hair for inducing, maintaining or 
increasing hair growth comprises: 
   (i) a first chemical inhibitor chosen 
from proteoglycanase inhibitors, glycosamino­
glycanase inhibitors, glycosaminoglycan chain

Title: Process for the preparation of pigmented metallic-base lacquers drying in the air, and their use
IPC: C09D5/38
Filed: 1988-03-22
Abstract: 2.1 Metallic basecoating compositions have hitherto frequently been obtained by mixing oxidatively drying alkyd resin binders which contain a siccative system with metal platelets in a physically drying binder. This gives rise to pronounced changes in hue and flop and also to undesirable cloudiness. The novel process shall avoid these disadvantages. 2.2 In the preparation of air-drying metallic basecoating compositions by mixing of metallic basecoating compositions which contain metal platelets and are based on physically drying binders with high gloss lacquers which are based on oxidatively drying alkyd resin binders and contain colour pigments of various hues, additional use is made of a mixture of solvent-dissolved cellulose ethers and/or esters or half-esters, as a result of which the deterioration in the coating properties is prevented. 2.3 Preparation of metallic basecoating compositions, in particular for the refinishing market.

Residual toner (88) on the belt is dislodged and drawn through a low pressure zone between each pair of cylinders leading to a filtered discharge outlet. The brushes (54) are cleaned by their interengagement along adjacent cylinder surfaces where the cylinder brushes (54) mesh and also between each cylinder brush (54) and a rake (74) therefor fixed to the housing (24).

of oligomer chains which contain chemically bound ethylene 
oxide units as hydratable groups, the ethylene oxide units 
being present in the form of oligomer blocks containing 
5-200 ethylene oxide units, for coating and/or

Patent EP-0299733-A3 (EP)
IPC: C25C3/08
Filed: 1988-07-13
Abstract: The amount of electrically conductive material in the 
bottom floor lining of a conventional aluminum reduction 
cell is reduced by using a non-conductive lining material 
in its place. The non-conductive material separates the 
remaining electrically conductive regions from the sidewall 
linings of the cell and preferably confines the electric­
ally conductive material to the "anode shadow" region of 
the cell floor. The non-conductive material preferably 
comprises a particulate alumina mixture made up of large 
shapes which firmly compact together and smaller particles 
which fill the remaining voids. Optionally, the mixture 
may be bonded together with amorphous alumina, in which 
case the mixture can also be used for cell wall linings. 
The linings can be used in reduction cells of conventional 
design and reduces undesirable magnetohydrodynamic effects 
as well as pollution hazards caused by conventional 
carbonaceous cell linings.

IPC: G01R31/28
Filed: 1988-03-11
Abstract: The apparatus disclosed removes oxide from the contact pads 
of the wafer under test. The apparatus has a test probe membrane 
(1-13) attached to a traveling device (1-3). The traveling 
device (1-3) attaches to a base (1-5) through one or more 
constant length pivoting devices (1-7) and one or more variable 
length springs (1-9). When a wafer pushes against the test probe 
membrane (1-13), the traveling device (1-3) moves upwards. The 
constant length pivotal device (1-7) and the variable length 
springs (1-9) control the sideways motion of the traveling device 
(1-3). When the traveling device (1-3) lifts from its resting 
position, it moves sideways and thereby allows the test probe 
membrane (1-13) to scrub the contact pads of the wafer under 
test.
Patent EP-0326338-A3 (EP)
IPC: H01M6/04
Filed: 1989-01-25
Abstract: The invention concerns batteries with aluminium 
alloy anodes, and generally aqueous alkaline 
electrolytes and cathodes. The anode in an alloy of Al 
with an activating element selected from Cd, Sn, Bi, 
Sb, In, Be, B, Se, Te, P, As, C, Re, Pd, Nb, Si and Zn. 
When the anode is polarized at a suitable electro-­
negative potential, typically from -1.8V to -2.3V 
relative to a Hg/HgO reference electrode, the anode 
operates in a new state, herein called a hyper-active 
state, in which the battery operates at a higher 
voltage and/or hydrogen gas is generated at a higher 
rate than in conventional aluminium batteries. The 
hyper-active state is maintained by control of anode 
potential (typically around -2.0V at low current 
densitites) and electrolyte hydrodynamics.
