Title: Apparatus for producing a pipe with annular ribs
IPC: B29C48/13
Filed: 1989-09-05
Abstract: The invention concerns apparatus for molding thermoplastic tubing having solid annular ribs. The apparatus is of the type where a tubular mold is defined by cooperatively interengaged mold block of a pair of mold assemblies. An annular extrusion orifice for the tube extends into the mold tunnel and tubing is extruded about a mandrel. The invention provides an accumulator chamber in the region of the extrusion nozzle to provide for pressure differences which build up at that point. Thus, the effective volume of the accumulator chamber can compensate for the varying requirement for the thermoplastic material resulting from the varying radial wall thickness.

Title: Apparatus for displaying the remaining charge of rechargeable battery
IPC: G01R31/36
Filed: 1989-09-13
Abstract: An apparatus having a rechargeable battery and a battery 
voltage detector which detects the output voltage of the battery 
to produce a detection signal when the output voltage falls below 
a predetermined threshold level. A controller stores a battery 
capacity value and accumulates the discharge of the battery to 
produce an accumulated capacity value. The controller also 
calculates a difference between the stored capacity value and the 
accumulated capacity value. Using the difference, a display 
displays the remaining charge value of the battery thereon. If 
the difference exceeds a predetermined value at a time the 
controller receives the detection signal, the controller changes 
the stored capacity value to a new capacity value. 
Alternatively, the controller may change a rate of accumulating 
the battery discharge.  
     The apparatus may have a current detector for detecting a 
current flowing through the battery. The controller may 
accumulate the battery discharge based on the detected current.

Title: Method of making ornaments
IPC: A44B19/26
Filed: 1989-12-13
Abstract: In a method of making an ornament, a metal 
ornament body (1) having an internal groove (7) opening 
at one end (7a) to an end edge of the metal ornament 
body (1) and at an opposite end (7b) to front and rear 
surfaces of the metal ornament body (1) is held between 
two relatively movable mold members (9, 10) while the 
one end (7a) of the internal groove (7) is connected to 
a gate (13) of the mold members (9, 10) and the oppo­
site end (7b) of the internal groove (7b) communicates 
with mold cavities (11a, 11b) in the mold members (9, 
10). Then, a melted synthetic resin material is in­
jected into the mold cavities (11a, 11b) through the 
gate (13) and the internal groove (7). Since the gate 
mark is not formed on the outside surface of an orna­
mental member (2) molded of synthetic resin but left on 
the end edge of the metal ornament body (1). The gate 
mark thus formed is normally hidden from view and does 
not deteriorate the aesthetical appearance of the 
ornament.

Title: Switchable mri rf coil array with individual coils having different and overlapping fields of view
IPC: A61B5/055
Filed: 1989-01-10
Abstract: An array of plural magnetic resonance imaging (MRI) RF coils is provided having different and overlapping fields of view. Controllable switches (52) are connected with each individual coil (16, 18) of the array and are capable of selectively conditioning any one of the coils for individual usage in an MRI procedure. Either mechanical or electrical (e.g., PIN diode) switching control (52) may be utilized. Preferably, controllable electrical switches are located at points having approximately zero RF potential. Distributed capacitance (CD) is also preferably employed for reducing terminal inductance, preventing the establishment of spurious magnetic fields and facilitating the use of electrical switching diodes and/or varactor capacitance elements. Such distributed capacitances are also dimensioned so as to cause the terminal inductance of each coil to be within the tuning/matching range of a common tuning/matching RF circuit (24).

Patent EP-0377993-A3 (EP)
Title: Sorting distributed data
IPC: G06F7/24
Filed: 1989-12-20
Abstract: A fast method for sorting data in a distributed data processing system is 
disclosed. Each processor P i  12i locally sorts its data into a local 
sorted file S i  34i, simultaneously producing an index to the sorted data 
and a file of key data records R′ 32 each comprising a key value paired 
with the processor's identifier. Each processor produces a distribution 
table DT i  28i of its key values using the index, and sends the table to a 
coordinator processor 18 which merges the processors' tables into a global 
distribution table GDT 30. The global distribution table assigns subranges 
of key values to the processors, and is broadcast back to them. Each 
processor then sends each paired key value and processor identifier to the 
processor assigned by the global distribution table to handle the subrange 
containing that key value. The processors receive and merge the incoming 
key data records simultaneously as they send such pairs to other 
processors. An output stream V i  36i consisting only of processor 
identifiers is created by each processor from the merged key value and 
processor identifier pairs, and is sent to the host H 16, which merges it 
into a global output stream of processor identifiers. The processors 
simultaneously send their local sorted files S i  to the host, which reads 
records from them in the order specified by the global output stream V.

properties different than the second ceramic material. The 
second ceramic material and the third ceramic material are 
preferably a zircon-based material and an alumina-based material, 
respectively. The resultant ceramic shell mold has a greater 
high temperature creep resistance than a shell mold formed solely 
from the second ceramic material or solely from the third ceramic 
material.
Patent EP-0385512-A3 (EP)
IPC: C09J7/35
Filed: 1985-05-28
Abstract: A heat-recoverable wrap-around sleeve for pipe protection, 
with a patch-type closure.  
     The patch is heat-stable and comprises two polymeric 
layers (4,6) bonded together through, for example, 
an open mesh glass-fibre fabric (8). No separate adhesive 
is required.  
     The hot modulus of one of the layers is low enough 
to enable it to bond to the overlapping edges of the 
wrap-around sleeve, and the hot modulus of the other 
layer is high enough to withstand installation temperature.  
     This new patch is easier to install and requires 
less materials than prior art patches, and does not need 
to be bonded to the sleeve in such a distinct heating 
step.

Patent EP-0403086-A3 (EP)
Title: Method for improving deposit of photoresist on wafers
IPC: G03F7/16
Filed: 1990-05-18
Abstract: A method for applying photoresist to a top surface 
(22, 24) of a semiconductor wafer (10) for defining an 
electronic circuit pattern. The wafer is placed on a 
horizontal turntable and a liquid solvent is dispensed 
onto the wafer's top surface. Spinning the wafer 
distributes a film (30) of the solvent to a 
substantially uniform thickness over the entire top 
surface. Liquid photoresist is dispensed onto the top 
surface of the wafer over the solvent film, preferably 
while the wafer is spinning, to distribute the 
photoresist in a layer (36) over the entire top surface 
of the water. Discharge of photoresist is controlled 
so that the top surface of the wafer remains entirely 
wetted by the solvent film during distribution of the 
liquid photoresist. The solvent has a lower viscosity 
than that of the liquid photoresist and the solvent 
film thickness is sufficient to enable the photoresist 
to fully cover any bare silicon, high density or 
undercut circuit features, generally in a range of 500 
to 10,000 Angstroms and preferably 1,000 to 5,000 
Angstroms.

Patent EP-0384900-A3 (EP)
Title: Overheating protection triggering circuit having a narrow range of variation of the threshold
IPC: H03K17/14
Filed: 1990-02-08
Abstract: An overheating protection triggering circuit for causing 
the switching-on of a guard transistor when a certain preset 
threshold temperature is reached employs a circuit for 
generating a reference current essentially proportional to a 
VBE/R1 where R1 is a preset resistance and a circuit formed 
by two complementary current mirrors, the first of which is 
emitter-degenerated by means of a preset resistance R2 in 
function of a certain area ratio (i.e. δVBE) of the mirror. 
The circuit basically performs a comparison between a 
reference current I1 = VBE/R1, strongly temperature 
dependent, imposed by the generator on the mirror circuit and 
a current I3 = δVBE/R2 relatively little dependent from 
temperature. With an increase of the temperature, the 
currents flowing in the two branches of the mirror circuit 
equal each other at a presettable threshold temperature thus 
causing the switching-on of a transistor. The temperature 
threshold is preset during the design by choosing a certain 
area ratio and a certain value for the resistance R2 of the 
first, emitter-degenerated current mirror and this 
temperature threshold is relatively insensitive to the normal 
spread of parameters.

Title: Adaptive boost switching preregulator and gain-variable current control
Inventor: VINCIARELLI PATRIZIO
IPC: H02M1/00
Filed: 1992-01-16
Abstract: A method is described for controlling the input current drawn by a switching power converter notwithstanding wide variations in load being supplied by the converter. The input current is controlled in response to a first signal. An input current control signal is generated based on comparing a second signal to a third signal. The second signal is independent of variations in the input current or the first signal. The third signal is dependent on variations in the input current and the first signal. The input current control signal is arranged to drive the value of the third signal towards the value of the second signal. The third signal is maintained and the magnitude essentially equal to the magnitude of the second signal. <IMAGE>

Title: Winding core with binding means for machines for tying packages.
Inventor: SCHUETTLER KARL-HANS
IPC: B65H63/08
Filed: 1994-02-15
Abstract: A [lacuna] onto a binding-means roll, with a winding core and with binding means located thereon, for machines for the tying of packages, the binding means being assigned a reflecting surface for especially photoelectric scanning for the purpose of marking its initial portion near the winding core, is characterised by an assignment of the reflecting surface to the initial portion of the binding means near the roll, such that, when the spent binding means exposes the reflecting surface, the initial portion still located on the winding core has a length which is sufficient for tying one package. The invention thus teaches, on the one hand, to activate the binding-means end marking only when there is still a binding-means portion sufficiently long for a further tying operation, and, on the other hand, nevertheless no longer to use up this portion which is available per se. This ensures, on the one hand, that there is no possibility of a machine fault, for example because there is no longer a sufficient residue of binding means for tying a package, and at the same time, on the other hand, that only an optimised minimum length of no longer utilisable binding-means material remains. <IMAGE>
