IPC: A61J1/00
Filed: 1982-05-19
Abstract: 1. Method of conditioning and utilization of a liquid involving its lyophilization, wherein : - in order to contain the liquid in the conditioning stage and in the utilization stage, there is employed one and the same container constructed in the form of a flexible bag having a first and a second wall (1) bonded along their external contour (82) so as to form an envelope and a rigid neck (6) which extends through said envelope in leak-tight manner, thus forming an opening of the bag ; - in the conditioning stage : the liquid container is partially filled with liquid, the container is placed in a substantially horizontal position on a support of the lyophilization device in such a manner as to ensure that a first wall and the neck are in contact with said support, the two walls being maintained in relatively spaced relation solely by the neck in the vicinity of this latter, said second wall is lifted in its remaining non-spaced portion so as to ensure that the liquid which rests substantially on said first wall has a free surface which is not in contact with the second wall, the liquid is cooled to freezing point, it is reheated in a vacuum while discharging through the neck the steam extracted by sublimation of the frozen product, the opening of the neck is hermetically sealed-off, said container is stored until direct utilization of the conditioned liquid ; - and in the utilization stage : the liquid is reconstituted by injecting water into the container without impairing leak-tightness, the reconstituted liquid is withdrawn from said container.

Title: Seal for a shaft
IPC: F16J15/3256
Filed: 1983-01-19
Abstract: A shaft seal has an annular housing with a first and a second flange and of a hollow, frustrated cone seal ring, the apex of which is anchored liquid-tight for rotation with axial displaceably but on the shaft. The large end of the conical sealing ring forms a sealing lip which bears elastically on the inner face of the second flange which is directed toward the medium to be sealed, having essentially the shape of the frustum of a hollow. The first flange forms an annular support surface (2) which bears on the seal ring (2) between the apex shaft gripping end and the sealing lip so that the shape of the seal ring is elastically deformed.

Title: Method and apparatus for measuring a tool of a machine-tool
IPC: B23Q15/16
Filed: 1983-05-06
Abstract: 1. A method of measuring the wear on a tool (12) which is received in a toolholder and is movable in a feed direction, the tip of the tool (12) being moved to a reference position in a reference plane and the position of the toolholder is then measured and is compared with a desired position which corresponds to the position of the toolholder when the non-worn tip is in register with the reference position (44), characterized in that, during travel of the tool (12) towards the workpiece (18) and/or during travel away from the workpiece (18), the tip of the tool passes through an optical measuring device (28, 30) having an optical measuring plane (44) which extends approximately transversely of the path of the tool and which serves as a reference position and detects the passage of the tip.
Patent EP-0094063-A3 (EP)
IPC: F16J15/32
Filed: 1983-05-06
Abstract: A rotary bidirectional dynamic shaft seal (10) for maintain­
ing a seal about a rotating shaft (12) to prevent the leakage of 
oil from the oil side of the seal past a sealing edge (18) to the 
air side. The seal (10) includes a plurality of pumping projec­
tions extending from the frustoconical surface (22) on the air 
side of the seal for pumping oil, which may leak past the seal­
ing edge (18) back to the oil side of the seal. The pumping pro­
jection has a primary pumping surface (24) extending axially 
from the sealing edge (18) and a secondary pumping surface 
(28) extending at a shadow angle (A) away from the primary 
pumping (24) surface to a return surface (26) which extends 
generally radially to define the rear extremity of the pumping 
projection. Under normal operating conditions, the primary 
pumping surface (24) will return oil to the oil side of the sealing 
edge (18). However, should the shaft (12) be misaligned or be 
running eccentrically, the primary pumping surface (24) will en­
gage the shaft on the minimum contact side whereas on the 
maximum contact side 180 degrees away, both the primary 
(24) and secondary (28) pumping surfaces will engage the 
shaft (12) to pump oil back to the oil side of the sealing edge 
(18).

Patent EP-0144913-A3 (EP)
IPC: C12Q1/70
Filed: 1984-11-29
Abstract: A nucleic acid hybridization assay involving a labeled 
probe and formation of a hybrid having epitopes for an 
antibody reagent. The label provides a detectable response 
which is measurably different when the labeled probe is 
comprised in a hybrid that is bound by the antibody reagent 
compared to when not comprised in such a hybrid. Particu­
larly useful antibody reagents are antibodies such as anti-­
DNA˙RNA, anti-RNA˙RNA and antibodies to intercalated 
duplexes which do not bind substantially to single stranded 
nucleic acids. Modulation of the label response can be 
accomplished in a variety of ways such as by steric 
inactivation or hindrance or by labeling the antibody reagent 
with a second label which interacts with the first label. The 
assay is particularly advantageous because no separation of 
hybridized and unhybridized probe is required.

IPC: G06F9/00
Filed: 1984-03-26
Abstract: A system for interfacing a Processor to a Coprocessor 
using standard bus cycles. The Processor, upon encountering 
in its instruction stream an instruction having a particular 
Operation word format, will transfer a Command word follow­
ing the Operation word to a particular Coprocessor desig­
nated by a Coprocessor Identity field in the Operation word. 
Upon decoding the Command word, the Coprocessor will 
respond with any of a set of response primitives which define 
functions which the Coprocessor requires to Processor to 
perform in support of the Command by the Coprocessor. The 
interface provides for all functions which the Coprocessor 
may require, including selective vectoring to appropriate 
exception handlers.

Abstract: An X-ray lithographic system and method for beam printing 
on a substrate such as a silicon semiconductor wafer includes a 
beam exposure chamber (11), a beam source (13), a mask holder 
(15), a mask (17) including a thin mask membrane (18) closing

Abstract: A station for testing one or more electric conductors (8) 
covered in insulating material (9) includes one or more 
contact probes (14) movable to pierce the insulation and 
contact the conductors (8). Additionally one or more contact 
pins (12), resiliently mounted in a mounting (11) are movable

Patent EP-0176279-A3 (EP)
Title: Tamper-resistant container closure
IPC: B65D41/48
Filed: 1985-09-10
Abstract: To resist tampering with the contents of container for pharmaceuticals and other products the neck (11) of the container is sealed with a commercially available foil seal (71); the cap (51) is dimensioned so that the foil seal is inserted inside the cap prior to its being applied to the container. The dimensions of the cap accommodate the foil seal yet the snap-on and tamper-proof features of the cap are maintained. A thin flange (86) projecting from the periphery of the cap is used to remove the cap in its reclosure mode; however, this flange is shaped so that if one attempts to use the flange to pry off the cap when in its original sealing mode, sufficient force cannot be applied. The present cap skirt (50) has upper and lower internal beads (57, 61) separated by a horizontal scoreline (81). The beads may be continuous or, preferably, interrupted. They may be closer together and closer to the top disc than in prior caps of this type. The upper bead may be much thinner than in prior structures. The skirt below the beads is elongated and frictionally engages the outside of the container neck to inhibit tampering. Various cap bead shapes are disclosed.
