Patent EP-0271006-A3 (EP)
IPC: H05K13/04
Filed: 1987-12-03
Abstract: A printed circuit board positioning apparatus includes 
a table (1) with a support member (2), a pair of circuit 
board guiding/transporting units (4,5), a first positio­
ning unit (51), and a second positioning unit (14,20). 
The pair of circuit board guiding/transporting units 
(4,5) is provided on the table (1) to be moved toward 
or away from the table (1), sandwiches both end faces 
of the printed circuit board (P) in a direction perpen­
dicular to a flowing direction (A) of the printed circuit 
board therebetween, and guides/transports the printed cir­
cuit board (P) in its flowing direction (A). The first 
positioning unit (51) positions the printed circuit board 
(P) in the direction (B) perpendicular to the flowing di­
rection (A) using the pair of circuit board guiding/trans­
porting units (4,5). The second positioning unit (14,20) 
elastically urges both end faces of the printed circuit 
board in its flowing direction, in association with ap­
proaching motion of the circuit board guiding/transporting 
units (4,5) toward the table (1), and before the printed 
circuit board (P) is supported by the support member (2) 
on the table (1).

IPC: G11C17/14
Filed: 1987-07-23
Abstract: An apparatus for programming an ECL PROM 
comprises conventional ECL row and column address 
circuits for selecting a particular fuse in the ECL 
PROM. The selection of a particular fuse in the ECL 
PROM generates a control signal in the address 
decoders corresponding thereto which enables a current 
drive gate and a current sink gate coupled thereto. A 
row program control circuit and a column program 
circuit are then enabled by an increase of potential 
applied thereto for turning on the current drive gate 
and the current sink gate coupled to the selected 
fuse. The turning on of the current drive gate and 
the current sink gate coupled to the selected fuse 
causes 50 to 100 milliamps to flow through the 
selected fuse, blowing the fuse.

Title: Mechanical low-noise press, particularly of the screw type
IPC: B30B15/00
Filed: 1989-05-29
Abstract: The present invention concerns a mechanical, low-noise press, 
particularly of the screw type, comprising a tup-bearing ram (12, 
28) connected with a driving screw (13, 24), rotatingly connected 
with a lead nut (14, 21-23), which is integrally fixed on the 
frame supporting the press (10). The press also comprises sealing 
means (18, 19, 30) which define, together with the mating 
surfaces of the screw and of the lead nut, at least one chamber 
(16, 31), having a pre-determined volume, adapted to collect an 
incompressible medium, such as lubricating oil, and circulation 
means (16, 17, 19, 20) in order to maintain within said chamber a 
controlled delivery of the medium. Such delivery insures the 
presence of a constant spacing film of medium between the mating 
surfaces during the operation phases of the press, so as to 
prevent, during such phases, the direct contact between the screw 
and the lead nut, thereby absorbing the vibrations and the 
collisions generated by their interaction.

Abstract: Der Neigungssensor enthält in einer Wanne (3, 3′, 8) eine frei 
bewegliche Kugel (4). Die Ruhelage der Kugel (4) auf der Wan­
nenwand (3, 3′, 13′, 13″) hängt davon ab, wie "schräg" die 
Wanne und damit auch das Gehäuse (1) des Neigungssensors zur 
Waagerechten liegen. Aus der Tatsache, daß die Kugel (4) in 
ihrer Ruhelage entweder zwei voneinander elektrisch isolierte 
Wannenbereiche, z B. den Wannenboden (7) und die Wannenwand 
(3′) miteinander verbindet oder nicht, ist jeweils abzuleiten, 
ob die Lage des Gehäusebodens (2) innerhalb oder außerhalb 
einer Klasse einer bestimmten Neigung liegt. Eine ringartige 
Unterteilung (13, 13′, 13″) der Wannenwandfläche erlaubt eine 
Klasseneinteilung des Betrages der Neigung, eine sektorale 
Unterteilung (10...10‴″), eine Klasseneinteilung der 
Richtung der Neigung. Durch eine Kombination der sektoralen und 
azimutalen Wannenwandteilung sind sowohl Richtung als auch 
Betrag der Neigung in einem Raster erfaßbar.

Title: Method to improve mrna translation and use thereof for production of platelet factor-4
IPC: A61K38/00
Filed: 1989-01-06
Abstract: The present invention provides a method to 
improve the expression of a poorly expressed recombinant 
protein, such as platelet factor 4, by constructing a gene 
fusion such that unfavorable secondary structure formed 
between the region of the messenger RNA specifying the 
recombinant protein and the region of the messenger RNA 
containing the ribosome binding site is disrupted. The 
gene fusion is constructed by inserting a DNA segment of 
sufficient length to disrupt unfavorable long-range fold­
ing interactions which render the ribosome binding site 
inaccessible to ribosomes thereby interfering with the 
translation of mRNA. The invention further provides for 
the expression of recombinant platelet factor 4 and 
provides recombinant DNA vectors and methods for the 
bacterial production and recovery of said platelet factor 
4.
Patent EP-0355957-A3 (EP)
Title: Multiple image, single display system and method
IPC: H04N5/445
Filed: 1989-06-22
Abstract: A multiple image, single display system (2) 
includes a monochromatic display source (4) which provides 
first and second rapidly alternating visual images (8, 10) 
which pass through an active polarizer assembly (14). The 
polarizer assembly includes an image polarizer (20), which 
polarizes all the light to a left hand circular 
polarization, and a polarization changer (22) coupled to the 
display source by a synchronizer (28). The polarization 
changer switches the polarization of the first image but not 
the second image. A first user (34) sees the first image, 
but not the second image, through a right hand circular user 
polarizer (16) while a second user (36) sees the second 
image, but not the first image, through a left hand circular 
user polarizer (18). The user polarizers are wave-length 
sensitive so they block light only if the light has the same 
polarization and if the light is the wavelength of the light 
produced by the display source; the user polarizers are 
otherwise transparent to visible light. This permits the 
invention to be used in critical low light situations.

Title: Automotive seat assembly and method of installing same
IPC: B60N2/015
Filed: 1989-07-24
Abstract: A vehicle seat assembly providing 
for increased access to the 
seat assembly frame for attaching the 
seat assembly (10) to the floor pan (13) of a 
motor vehicle. The increased access is 
provided by pivotally mounting 
the seat cushion (22) to the seat 
support frame at the rearward edge of the 
seat cushion. This allows the seat 
cushion (22) to be pivoted upward to a 
position parallel to the seat back (20) 
such that the support frame of the 
seat assembly (10) is exposed. In this 
exposed position the seat assembly (10) can 
be carried by a robot and placed 
into position in the vehicle and 
provides access for a robot to attach 
the support frame to the floor pan (13) 
of a vehicle. Once the seat assembly (10) 
is attached, the seat cushion (22) is 
rotated downward into position on 
top of the support frame. An attaching 
means is provided on the seat cushion (22) 
and support frame to hold the 
cushion (22) in place.

Title: Improved pressure-modulated infrared gas analyzer and method
IPC: G01N21/35
Filed: 1990-03-07
Abstract: A gas analyzer (10) for detecting low concentrations of 
a specific gas which has a sample chamber comprising 
passages (14, 30, and 32) through which radiant energy is 
directed and which is pressure modulated by a loud speaker 
(36) both of which provide a radiant energy signal which is 
detected by a beam splitter (82) having a measurement 
channel (86) directed to a measurement detector (92) and a 
reference channel (84) with a reference cell (94), 
containing gas of the type being analyzed, directed to a 
reference detector (90). Both detectors (92, 90) produce a 
signal which is processed by an algorithm. The loudspeaker 
(36) is isolated from the sample chamber by a flexible 
diaphragm (42) to eliminate phase changes in the pressure 
modulated output of the loud speaker (36). Means are 
provided for measuring the modulation or AC pressure and 
the steady state or DC pressure in the sample chamber, the 
radiant energy modulation, the humidity in the sample 
chamber and the temperature of the analyzer as parameters 
for processing by the algorithm.  
     Also disclosed is a method of detecting low 
concentration of a specific gas.
