Patent EP-0326752-A3 (EP)
IPC: D05B27/22
Filed: 1988-12-05
Abstract: An upper feed mechanism of a sewing machine, 
in which the horizontal motion mechanism for moving 
the upper feed dog (19) back and forth is provided 
with a double lever mechanism composed of a linear 
lever (4), a bifurcate lever (6) and a slider (5) 
slidably mounted on both levers, and a crank lever 
mechanism (13, 14) for oscillating the levers.  
     When a crank of the crank lever mechanism 
(13, 14) is at the top dead point or the bottom dead 
point, the axial lines of the linear lever (4) and the 
bifurcate lever (6) are matched, and when the slider 
(5) is moved in this state, the upper dog (19) varies 
in the feed amount while the front position or rear 
position is constant. When a rod for coupling the 
crank and lever of the crank lever mechanism is 
pivotally mounted on one of the two positions spaced 
in the peripheral direction with respect ot the lever, 
the upper feed dog (19) fitted and disposed at the 
presser foot makes an upper feed motion before the 
needle drop point, and when it is fitted to the other 
position, the upper feed dog disposed behind the 
presser foot makes an upper feed motion behind the 
needle drop point.

IPC: B02C15/16
Filed: 1989-04-14
Abstract: Die Erfindung betrifft eine Luftstrom-Mahlanlage mit einer 
Wälzmühle, die stationär gelagerte Mahlwalzen aufweist. Die 
Mahlwalzen (20) sind federnd gegen eine angetriebene Mahlschüs­
sel (3) anpreßbar. Über der Wälzmühle ist ein integrierter Sich­
ter angeordnet. Das Mahlgut-Luftgemisch wird bei dieser Aus­
führungsform der Mahlanlage im wesentlichen vom Wälzmühlen­
zentrum her der Mahlschüssel und den Mahlwalzen (20) zugeführt. 
Da bisher die Drehung der Mahlwalzen durch reinen Reib­
schluß mit dem Mahlgut bzw. der Mahlschüssel herbeigeführt 
wurde, konnten extreme Belastungen und Slip-stick-Effekte 
nicht ausgeschlossen werden. Die Erfindung geht zur Über­
windung dieser Nachteile den Weg, in einer Kombination auch 
die Mahlwalzen (20) separat anzutreiben (26), wobei Drehzahl und Dreh­
moment so ausgelegt werden, daß auch bei hoher Feinheit des 
Mahlgutes eine gleichmäßige Funktionsweise der Mahlanlage 
gewährleistet ist.

Title: Method for the preparation of polyorganosiloxane and radiation-curable composition
IPC: C08G77/50
Filed: 1989-12-14
Abstract: Polyorganosiloxane having the substructure 
  
where R⁸ is a divalent group generated by an addition 
reaction between SiH and acryloxy, methacryloxy, or 
alkenyl group and R⁹ is acryloxy, methacryloxy, or 
alkenyl, is prepared by an addition method in which an 
organopolysiloxane having two kinds of unsaturated groups 
selected from acryloxy, methacryloxy, and alkenyl and 
organohydrogenpolysiloxane are reacted in the presence of 
a platinum-type catalyst. These organopolysiloxanes are 
prepared without gelation and the method is highly 
efficient.  
     Radiation-curable compositions based on the 
polyorganosiloxane are characterized by a rapid cure upon 
exposure to radiation, while resisting curing inhibition 
even in the presence of oxygen, to give a cured material 
whose cured surface is slightly subject to time-dependent 
changes, and in particular whose peeling or release force 
undergoes little variation with the passage of time.
Patent EP-0377164-A3 (EP)
Title: Lru error detection using the collection of read and written lru bits
IPC: G06F11/10
Filed: 1989-12-18
Abstract: A least-recently used (LRU) storage means and its 
associated logic maintain usage history for 
associativity class entries of a cache directory. The 
storage means includes an independent storage array 
for each of six bit positions of an LRU binary code 
pattern. Parity bits are provided in the arrays for 
each LRU bit. Separate read/write controls 
simultaneously write three update LRU bits to three of 
the arrays and read out three unchanged LRU bits from 
the remaining three arrays during updating of a usage 
history entry when its associativity class is used. 
Pattern checking logic collects the update bits and 
the unchanged bits during the update write/read cycle 
to determine whether or not the new entry is a valid 
LRU combination. A parity bit is written with each 
of the three update LRU bits written into the arrays 
and parity bits are read out from the arrays with the 
three unchanged LRU bits for parity checking of each 
unchanged LRU bit during updating of usage history 
entries.

Patent EP-0351200-A3 (EP)
Title: Liquid crystal display apparatus
IPC: G02F1/13363
Filed: 1989-07-11
Abstract: A twisting nematic liquid crystal display apparatus (1) 
rotates the plane of polarization of the light with optical 
rotatory power of liquid crystal layer (2), thereby 
display operation is made by switching pass/interruption of 
the light by means of a pair of polarizers (8a, 8b) 
sandwitching the liquid crystal layer (2). At this time, by 
associating an optical compensating member (3) whose optical 
anisotropy is in the opposite characteristic with a liquid 
crystal display device, leakage of light and coloration 
caused by birefringence and optical rotatory dispersion 
in the liquid crystal layer (2) are prevented, the switching 
characteristic of the light over the entire visible light 
region is enhanced, and color display is high in contrast 
ratio. Since the optical compensating member (3) is formed 
of laminated and adhered plural synthetic resin films which 
are extended monoaxially, and twisted in the opposite 
direction to twisting direction of liquid crystal molecule 
on the plane including the extending direction, the quality 
of display may be improved without deterioration of the 
advantages of the existing liquid crystal display apparatus 
such as small size and portability.
