Patent EP-0194869-A3 (EP)
IPC: B29C49/64
Filed: 1986-03-12
Abstract: A method for forming deep drawn highly oriented 
thin-walled thermoplastic articles including the steps of 
planarly supporting a sheet of at least partially crystalline 
thermoplastic polymeric material and establishing at least 
one differentially heated area within the sheet. The differen­
tially heated area is to include an outer cool zone having a 
temperature range generally below the crystalline melt point 
of the thermoplastic material, a hot zone disposed within the 
outer zone having a temperature range generally above the 
crystalline melt point but below the complete melt point of 
the thermoplastic material, and an inner cool zone located 
centrally of the hot zone having a temperature range 
generally below the crystalline melt point of the thermoplas­
tic material. The heated sheet is placed between a female 
mold unit and a forming mandrel with the inner cool zone 
generally axially aligned therewith. The mandrel is driven 
against the inner cool zone of the heated sheet and into the 
female mold unit so that the thermoplastic material is drawn 
radially inwardly toward the inner cool zone and around the 
mandrel forming an elongated generally cylindrical shaped 
preform having a central cavity. The material is longitudinal­
ly stretched a distance sufficient to cause at least a portion of 
the walls of the preform to undergo strain hardening while 
the outer cool zone maintains tension control of the sheet 
material throughout the forming process. The central cavity 
of the elongated preform is then subjected to internal fluid 
pressure to radially expand the preform against the interior 
surface of the female mold cavity. The fluid pressure is 
maintained for a time sufficient to allow the expanded 
material to cool and set.

IPC: G06F3/06
Filed: 1987-10-13
Abstract: This invention relates to a method of reducing res­
ponse time to I/O requests to access data stored in a 
plurality of circulating storages devices. More 
specifically, data is duplicated on the circulating 
storage devices. The access time of accessing an 
originally stored data unit and a duplicate of that 
data unit is estimated and the data unit requiring the 
lesser access time to be accessed is then accessed. 
This invention also describes the method of writing or 
storing data in the direct access storage device. 
More specifically, data is stored through the use of 
high priority queues and low priority queues. Requests 
to originally store data or the first copy of data is 
stored in a high priority queue, while the request for 
storing the copy of the originally stored data is 
stored in a low priority queue. Then, all requests in 
the high priority queue are satisfied, before any 
request in the low priority queue is satisfied.

Title: Process and apparatus for the dosage of liquid samples
IPC: G01F11/02
Filed: 1987-12-15
Abstract: First and second containers (R1; R2) are successively brought to a transvasation or decanting station (C) in which the samples are metered. For this purpose, a piston (17) is mounted so as to be able to penetrate each first container (R1), which can be lifted, when it enters the decanting station (C). The quantity of sample in the first container (R1) is greater than the quantity to be precisely metered which is poured into the second container (R2) by means of a pouring assembly (24 to 36) situated above it. A pouring member (40) may be placed between the second container and the pouring assembly. Thus, when the first container acts as cylinder on the piston (17), a first quantity of the sample rinses the transvasation or decanting circuit to eliminate any residue of a preceding sample, while the pouring member is located between the pouring assembly (24 to 36) and the second container, then an exactly metered quantity of the sample is poured into the second container after withdrawal of the pouring member ( 40).

IPC: H01L21/316
Filed: 1987-06-11
Abstract: This invention is a method of manufacturing devices including a 
semiconductor/dielectric interface (e.g. interface between semiconductor layer 
24 and dielectric layer 25) wherein at least a monolayer of said dielectric layer is 
in an ordered state. Dielectric compound layers having ordered interface 
structure can be produced on strained semiconductor materials, e.g., by native 
growth. For example, a 5 x 5 reconstruction at the interface between silicon 
and silicon oxide results upon oxidizing a thin layer of (111)-silicon which is on a 
layer of relaxed germanium-silicon. Also, an ordered silicon oxide can be grown 
on a (100)-silicon surface which is atomically smooth or whose surface steps are 
two monolayers high. Ordered surface structure is of interest in semiconductor 
device technology, e.g., at the interface between silicon and passivating silicon 
oxide and wherever a highly defect-free interface is beneficial.

IPC: G01R15/24
Filed: 1987-08-19
Abstract: Apparatus and method for compensating a photo sensor 
for losses in fiber optic cable leads or connectors and fluc­
tuations in optical source power make use of a selected broad­
band optical source (10) in conjunction with a photoelastic 
fiber optic transducer (29) that uses a polarizer (26) and 
an analyzer (32) to polarize a part of the broadband signal. 
The part of the signal that is not polarized is transmitted 
through the photoelastic transducer (29) with no modulation, 
whereas the part of the signal that is polarized is modulated 
according to the stress on the photoelastic transducer. 
After transmitting the output light beam through a fiber 
optic cable (38), the beam is separated into two parts (44,46). 
The second part (46) is filtered so as to transmit only 
that part of the broadband signal that is not affected by 
the polarizer and analyzer and hence is not modulated, the 
filtered second part being converted to an electrical signal 
by a photo detector (54). The first part (44) of the split 
beam is filtered so as to transmit only that modulated part 
of the broadband signal that is affected by the polarizer 
and analyzer, the filtered first part being converted to 
an electrical signal by a photo detector (50). The first 
signal varies according to the lead and connector losses 
and the stress modulation on the photoelastic transducer 
(29), and the second signal varies according to lead and 
connector losses only. The ratio of the first signal to 
the second signal then provides a measure of the changes 
in the transmission due to the modulation of the stress trans­
ducer, without lead and connector losses.

Abstract: A film drive (83) in a camera is actuated 
to advance a filmstrip (F) from a cartridge (C) to 
position respective frames on the filmstrip for 
exposure. Normally the film drive is disabled to 
prevent advancement of the filmstrip when the camera 
is in a non-picture taking or storage condition, as 
for example when an integral lens cover (1) of the 
camera is closed. An exception is created, however, 
whereby the film drive may be actuated to initialize 
a fresh film load by advancing the filmstrip to 
position its first frame for exposure even though the 
lens cover is closed. This is possible when 
respective sensor devices (SW C , SW F ) in the 
camera determine that a cartridge is in the camera 
but the filmstrip has not been initialized. Exposure 
of the first frame on the filmstrip can not occur 
unless the lens cover is opened.

Title: Method and device for measuring the speed of vehicles
IPC: G01P3/66
Filed: 1988-04-25
Abstract: Let into the roadway (F) transversely to the driving direction (A) is a pair of pressure-sensitive detector cables (1, 2) which, when a vehicle passes, transmit signals from which the driving time for the distance (D1) between the detector cables (1, 2) is determined. The signals (I1, I1', I2, I2') triggered by each axle of a vehicle when each detector cable (1, 2) is driven over are processed and used to determine the driving time (T2, T3) of the respective axle. A plurality of time intervals are determined in this way and evaluated for the purpose of speed measurement. The determination of a plurality of time intervals enables measurement to be monitored and thus an increase in the reliability of measurement in conjunction with only a minimum increase in outlay.   <IMAGE>

Abstract: An anatomically form-fitting, generally self-adjusting 
disposable diaper (10) comprises an absorbent structure and an outer 
cover (12) for positioning the absorbent structure against the body to 
absorb and contain body wastes. The outer cover (12) includes front (28) 
and rear (30) waist panels resiliently stretchable in a cross-body 
direction and defining an elastically contractible or expansible 
waist opening (W) which provides a fit line when the garment is secured 
about a wearer. An abdominal support zone which corresponds to 
the lower abdominal region of the wearer spaced longitudinally 
away from the waist opening and extending across at least the 
central portion of the front panel, imparts a tensile stress thereto 
which is greater than that of the remaining front panel and waist 
opening. This support band (65) can comprise a strip of material which 
has a relatively greater or less modulus of elasticity than the 
remaining front panel and waist opening. It can also be provided 
by a fastening system having shaped inelastic landing zones 
appointed on the front panel which preferentially direct tensile 
stresses across the support zone.

Title: Electrode substrate with integral edge seal and method of forming the same
IPC: H01M8/02
Filed: 1989-02-28
Abstract: The edges of a porous substrate plate (2) used in a fuel 
cell power plant are densified by impregnating a suspension 
of finely divided material in the interstitial spaces in 
the plate edges. The suspension, in the form of an "ink" 
is forced into the plate edges via a pressure differential 
applied through the plate between two press blocks (50,60). The 
ink is forced into the plate after a catalyst layer (4) has 
been applied to one surface of the substrate plate. The 
ink thus penetrates to the inner surface of the catalyst 
layer, and also forms an integral filler band outwardly of 
the catalyst layer, which filler band has a top surface 
which is coplanar with the top surface of the catalyst 
layer. After the impregnation step, the seals are dried to 
form a dense low porosity border on the substrate plates 
which will fill with electrolyte to form a wet seal that 
prevents gas crossover through the edges of the substrate 
plates.
