Title: Gene-technological process for the preparation of human interleukin-2, and device for carrying out this process
IPC: C12N15/26
Filed: 1985-05-22
Abstract: A synthetic DNA sequence can be used to obtain human interleukin-2 in a genetic engineering process. The gene is advantageously synthesised in the form of a plurality of fragments which are ligated enzymatically to give larger part-sequences which are incorporated into hybrid plasmids and amplified in host organisms. The part-sequences are reisolated and then combined to give the complete gene and incorporated into a hybrid plasmid, and the latter is expressed in a host organism.

Abstract: The present invention discloses a method of and appar­
atus for drying slurry. The apparatus (10) comprises an upper 
plate member (12) and a lower plate member (14), which 
when placed together form a closed chamber (26) into which 
slurry (48) is poured. Downwardly depending side walls and 
end walls (24) of the upper plate member (12) are pressed 
against the lower plate member (14) to seal the chamber (26). 
Compressed air is supplied to a continuous groove (32) in a 
lower edge (30) of the side walls and end walls (24) and flows 
over the inside surfaces (54) of the side walls and end walls 
(24). In addition, compressed air is also supplied to the 
chamber (26), at a pressure slightly less than the pressure of 
the air supplied via the groove (32), the combined pressure in 
the chamber (26) forcing liquid from the slurry (48) in the 
chamber (26) through a porous medium (16) in the bottom of 
the chamber (26). Air from the continuous groove (32) assists 
in releasing the dried slurry from the chamber (26) when the 
upper and lower plate members (12, 14) are separated.

Abstract: An imprinter (1, 60) for imprinting characters from a credit 
card (2) onto a docket (3) comprises a base (4) of plastics 
material, and a carrier (16, 70) slidably movable across the 
base (4) having imprinter rollers (17a, 17b) to imprint charac­
ters onto the docket (3).  
     The base (4) has a receiving area (8), to receive a credit 
card and a flat upwardly facing panel (10), to receive a docket 
(3). The carrier (16, 70) transversely spans the base (4) and is 
longitudinally slidably movable over the document supporting 
panel (10) from a start position at one end of the panel (10) to 
a reversing return position at the other end of the panel (10) and 
back to the start position. Cam blocks (48, 49, 68) integrally 
moulded with the base (4) cooperate with cam followers (42, 
61, 62) mounted in the carrier (16, 70) to move the imprinter 
rollers (17a, 17b) from a raised inactive position to a lowered 
imprinting position engaging a docket (3) to imprint characters 
from the credit card (2), merchants plate (14) and dating 
mechanism onto the docket (3) during movement of the carrier 
member (16, 70) between the start and return positions.  
     Track means (20) are provided on the base (4), and the car­
rier (16, 70) includes four pairs of spaced apart roller bearings 
(26, 27) which engage opposing faces (21, 22) of the track

Abstract: Structure and method are disclosed for providing 
timed valving in which a nutating plate (90) having an opening (91) 
defined therethrough moves relative to at least one other 
nominally static plate (87) having a complementary opening (88) 
defined therethrough, the nutating plate (90) at one portion 
of the nutating travel bringing the opening (91) defined 
therethrough in alignment with the complementary static 
opening (88) and in another portion of the nutating movement 
positioning such opening (91) therethrough in a spaced, 
sealing relationship relative to the complementary static 
opening (88). Either the nutating or nominally static plate 
may be utilized in pairs such that a sandwiched relation­
ship between one type of plate and the other exists. The 
walls of the opening in the static plate are angularly 
disposed with respect to the walls of the opening defined 
in the nutating plate and steadily converge in the 
direction toward the nutating plate thereby restricting 
the opening in the static plate at the face adjacent to 
the nutating plate, with the angular disposition and 
convergence being configured to reduce turbulent flow 
during opening and closing of the valving structure. 
Timing of the opening and closing of the valving structure 
may be adjusted relative to the drive shaft so as to 
provide opening and closing cycles of selected portions 
of an entire rotation.

Abstract: Hot cathode type discharge lamp apparatus of the 
invention is composed of a tube for discharge lamp, a cathode 
electrode member in nearly cylindrical form made of a 
semiconductor porcelain and arranged within the tube and 
including a longitudinal circumferential surface made a 
discharge surface, and two lead wires connected to both 
longitudinal ends of the cathode electrode member and 
penetrating an end portion of the tube. In the discharge 
lamp apparatus, since an electron emission material is not 
used in the cathode electrode but the semiconductor 
porcelain is used, activation of the electron emission 
material due to heating is not produced, thereby blackening 
phenomenon of the tube wall of the discharge tube can be 
prevented and the life becomes long.

IPC: H05K1/03
Filed: 1987-11-11
Abstract: A method forming high density multilayered glass-ceramic 
circuits with copper conductors is disclosed herein. In 
the process a preburnoff process is performed in an 
atmosphere including nitrogen gas with a very low 
partial pressure of oxygen, with the glass-ceramic 
temperature being raised gradually from 25°C to the 
binder burnout temperature. Burnout of the residual 
carbon in the binder material is then performed by 
maintaining that temperature for several hours in the 
presence of wet nitrogen gas and hydrogen, with a ratio 
of water vapor to hydrogen gas of 10⁴. The temperature 
is, then, lowered to at or slightly below said binder 
burn off temperature for approximately one hour. 
Subsequently, the temperature is raised to the 
coalescence and/or crystallization temperature of said 
ceramic material and held for two hours while remaining 
in the dry forming gas environment.

Abstract: Liquid crystal material is operable to alter 
the reflection characteristics of a mirror, for 
example to provide day/night rearview mirror 
functions. In one embodiment the liquid crystal 
material (12) may be selectively energized or 
deenergized to provide two different levels of 
reflection,  i . e ., substantially full or reduced 
levels of reflection of incident light. In another 
embodiment analog adjustment of the level of 
reflection is possible preferably together with 
selectivity of full or reduced level reflection. 
Briefly, the mirror includes a mirror support (22), a 
reflector (10, 11) to reflect light incident thereon, 
and liquid crystal material (12) for determining the 
amount of light reflected by the reflector (10, 11). 
The mirror may include plural reflectors (10, 11) 
with liquid crystal material (12) between the 
reflectors and selectively operable primarily to 
transmit or primarily to scatter light to determine 
from which of the reflectors incident light primarily 
is reflected. Alternatively, the reflector may be a 
single reflector (10′) and the liquid crystal 
material (12′) then would include volumes of liquid 
crystal with pleochroic dye in a containment medium, 
all mounted with respect to the support (22) for 
selectively attenuating light.

Title: Shaped ceramic composites and methods of making the same
IPC: C04B35/71
Filed: 1987-04-30
Abstract: A method of producing self-supporting ceramic composite bodies of desired shaped by infiltrating a permeable preform with polycrystalline matrix material consisting essentially of an oxidation reaction product obtained by oxidation of a parent metal precursor, such as aluminum, and optionally containing therein metallic constituents. The composite body is formed by contacting a zone of a permeable preform, having at least one defined surface boundary spaced from said contacting zone, with a body of molten metal which is reacted with a suitable vapor-phase oxidant to form an oxidation reaction product. Within a certain temperature region, and optionally with one or more dopants in or on the parent metal or said permeable preform, molten parent metal migrates through previously formed oxidation reaction product into contact with the oxidant, causing the oxidation reaction product to grow into the preform toward said defined surface boundary so as to infiltrate the preform up to said defined surface boundary, and provide the composite structure of desired geometry.
