Filed: 1988-03-17
Abstract: An apparatus (72) for use in a photocopier or 
the like in which sheets (C) can be fed automatically from a 
cassette (73) or manually from a manual-insertion tray (75) to a pair

IPC: F16C19/54
Filed: 1988-09-08
Abstract: Bei den bisher bekannten Kreiselpumpen mit auf 
der Antriebswelle fliegend gelagertem Laufrad 
erfolgt die Lagerung der Antriebswelle im 
Lagergehäuse über zwei Radiallager und ein 
Axiallager. Diese bekannten Lager sind in ihrem 
konstruktiven Aufbau nicht nur verhältnismäßig 
kompliziert und kostenaufwendig, sondern auch 
ihre Lebensdauer ist verhältnismäßig gering, da 
sie im Betrieb der Kreiselpumpe hohen Wechsel­
beanspruchungen ausgesetzt sind. Auch die Lauf­
eigenschaften des Laufrades und der damit ver­
bundene Wirkungsgrad der Pumpe werden durch 
vorzeitiges Auftreten von unerwünscht großem 
Lagerspiel nachteilig beeinflußt. Gemäß der 
Erfindung werden jedoch diese Nachteile in ein­
facher Weise dadurch beseitigt, daß zur Lage­
rung der Antriebswelle (1) im Lagergehäuse (8) 
zwei Radiallager (9, 10) und zwei Axiallager 
(11, 12) vorgesehen sind.

Title: Contact lens disinfection case with locking mechanism
IPC: A61L12/08
Filed: 1988-09-15
Abstract: A contact lens disinfection case includes a hollow cylindrical body with two open ends, and first and second end caps mounted on the open ends of the body to define with the body a fluid-tight housing. A contact lens holding basket is mounted on and is removable with the first end cap. An elongate locking member extends through the hollow body and engages the first and second end caps when the end caps are mounted on the body. The second end cap, when mounted on the body, abuts against the elongate locking member and causes it to engage the first end cap, locking it in place and preventing its removal. When the second end cap is not mounted on the body, the elongate locking member is positionable in non-engagement with the first end cap, allowing the first end cap to be removed from the hollow body.

Patent EP-0323712-A3 (EP)
Title: Process for the production of diphenols
IPC: C07C409/12
Filed: 1988-12-05
Abstract: A process for the production of dihydric phenols is disclosed which comprises oxidizing diisopropylbenzene (DIPB) with molecular oxygen to obtain a reaction mixture (A) comprising at least diisopropylbenzene dihydroperoxide (DHP) and diisopropylbenzene monocarbinol monohydroperoxide (HHP), the DIPB, DHP and HHP being optionally substituted; supplying to an agitation reactor (1), an oily phase comprising a solution of the reaction mixture (A) in an aromatic hydrocarbon solvent, and (2), an aqueous phase comprising hydrogen peroxide and an acid catalyst at a feed rate of 1 - 5 moles of hydrogen peroxide per mole of HHP in the reaction mixture (A), the acid catalyst being present at a concentration in the aqueous phase of 10 - 40% by weight, the concentration of hydrogen peroxide in the aqueous phase being at least 20% by weight, and the weight ratio of the oily phase to the aqueous phase being at least 10:1; allowing the HHP to be oxidised by hydrogen peroxide into the corresponding DHP at a reaction temperature at 30 - 60 DEG C so that a reaction mixture (B) is obtained; separating the aqueous phase from the oily phase in the reaction mixture (B); and subjecting the DHP in the separated oily phase to acid cleavage to form the corresponding, optionally substituted, dihydric phenol. The process represents an improvement over prior art processes in that it allows removal of the reaction water and recirculation of the aromatic hydrocarbon and the aqueous phase to be dispensed with whilst allowing a higher ratio of oily phase to aqueous phase to be achieved. This reduces the amount of hydrogen peroxide and acid catalyst needed, thereby decreasing the reaction time.

Title: Method of and apparatus for compressing image data
IPC: H04N7/26
Filed: 1989-06-22
Abstract: Image data (f ij ) depicting an image in a pixel block 
are converted by 2-D Discrete Cosine Transformation into 
transformation coefficients (F mn  or F mn *). Only a part of 
the coefficients are employed to form compressed image data 
(D t ). The selection of the part of the coefficients is 
executed using code tables (CT). Several groups of code 
tables are prepared, and one of those groups is selected in 
the data compression operation in response to a standard 
deviation (σ) of the image data in the pixel block. When the 
compressed image data is restored, identification data 
specifying the selected group in the previous data 
compression is stored in the restored image data. Then, in 
the next data compression of the restored image data, the 
selected group is again selected as a function of the 
identification data.

with a vector processor to predict, before the 
completion of the translation of the virtual addresses 
of all of the data elements of a vector, the valid 
performace of all virtual-address to physical-address 
translations for the data elements of the vector. The 
prediction logic device asserts an MMOK signal to a 
scalar processor when it becomes known that no memory 
management fault and/or translation buffer miss will 
occur such that the scalar processor can resume vector 
instruction issue to the vector processor at the 
earliest possible time.

Abstract: A process for making a film having a porous core 
layer and nonporous outer layers is disclosed. The 
film is selectively permeable and suitable for 
controlled atmosphere packaging end uses. The film is 
made from a composition of certain ethylene polymers, 
a particulate filler which has little affinity for 
the ethylene polymer, and optionally an organic 
compound which decreases the tendency for affinity of 
the particulate for the polymer. The film is 
produced by extruding the composition through a die 
gap of at least 250 µm, subsequently stretching 
the film after cooling to a temperature below the 
melting temperature of the polymer, selecting the 
composition, die gap and stretching conditions to 
form a film having a substantially nonporous surface 
and a porous interior.
