Patent EP-0330105-A3 (EP)
IPC: G01F1/684
Filed: 1989-02-18
Abstract: A microbridge air flow sensor has a silicon nitride diaphragm 
(14) formed on the surface (12) of a single crystal silicon 
wafer (11). A rectangular 500 angstrom thick sacrificial layer 
(13) was deposited on the silicon surface (12) before the 
silicon nitride to define the exact position of the diaphragm. A 
series of etches from the backside of the wafer is performed to 
fabricate the device. A first silicon anisotropic etch from the 
backside is stopped at the sacrificial layer. A sacrificial 
layer selective etch is applied from the backside first pit 
(19′) to the sacrificial layer (13) to remove all of the 
rectangular sacrificial layer. Anisotropic etch is again applied 
into the space (27) created by the removal sacrificial layer 
whereby the second etch attacks the silicon (28) exposed by the 
removal of the sacrificial layer and etches downward forming a 
second anisotropic etch pit (29). Thus all the etches are from 
the backside of the silicon wafer.

Abstract: Bei einem Verdampferbrenner für Standheizungen für Kraft­
fahrzeuge entstand früher nach Abschalten der Brennstoff­
zufuhr und dem anschließenden Abreißen der Flamme stören­
der Blaurauch, da Restbrennstoff lediglich erwärmt, nicht 
jedoch verbrannt wurde. Erfindungsgemäß wird nach dem 
Abschalten der Brennstoffzufuhr (B) die Glühkerze (3) für eine 
bestimmte Zeitspanne während der Nachlaufphase des Ver­
brennungsluftgebläses eingeschaltet. Dadurch wird prak­
tisch jeglicher Restbrennstoff verdampft und verbrannt 
und somit eine Bildung von Blaurauch sowie die Bildung 
von bleibenden Verbrennungsrückständen im Bereich des 
Kerzenstutzens und/oder des Brenners vermieden.

Title: Hosiery manufacture and packaging
IPC: B65D85/18
Filed: 1987-07-13
Abstract: A pair of hose are mounted on a card (11) 
for purpose of display or sale; the card is inserted 
into one hose (10) and the other hose (12) is placed 
inside the first hose, between the latter and one 
surface of the card. Machinery (20) for so assembling 
the hose and card has two supports (21, 28) and 
means to transfer a first hose (10) from its support 
(21), with eversion, to a holder (39, 40) 
in which a former (11) is held. The second hose 
(12) is everted by suction into its support (28) 
and is then conveyed pneumatically into a hollow 
interior of the holding means, thereby placing it 
inside the first hose (10) and to one side of the 
former (11). The former (11) and the two hose assembled 
therewith are then extracted from the holder (39, 40), 
the first hose (10) slipping from around the holder 
(39, 40) into an encircling relationship in contact 
with the former (11). The supports (21, 28) can 
be part of a toe closer which closes the toes of 
the two hose immediately before they are assembled 
with the former.

Title: Self equalizing multi-stage radio frequency power amplifier
IPC: H03F3/191
Filed: 1989-11-10
Abstract: Linearity and efficiency of a radio frequency two-stage 
power amplification device (10) are increased by employing 
two tuned circuits 16 and 18 in a driver stage (12) and two 
tuned circuits (22 and 24) in a high power stage (14). After 
selecting elements of tuned circuits (22 and 24) in order to 
optimize the high power stage (14) for efficiency, linearity 
and power output, elements are selected for tuned circuits 
(16 and 18) in order to cause the intermodulation output 
components associated with the driver stage (12) to have a 
180° phase angle relative to the intermodulation output com­
ponents associated with the individual high power stage (14). 
This phase angle relationship will cause the intermodulation 
output component products from the driver and high power stages 
(12, 14) to cancel.

Abstract: A pad of sheets each including a layer of flexible polymeric material having a coating of repositionable pressure sensitive adhesive on a second end portion while being free of adhesive along a visually distinctive first end portion in a stack with adjacent ends of the sheets aligned and with the first and second ends of successive sheets adjacent. The stack can be disposed in a chamber partially defined by a top wall having a slot through which the first end portion of the uppermost sheet projects. Relative movement is afforded between the top wall and the uppermost sheet to afford, as the uppermost sheet is pulled through the slot, alignment of the slot with successive portions of the uppermost sheet towards its second end as those successive portions are peeled from the stack. In a final relative position between the top wall and the uppermost sheet the slot is along the second end portion of that sheet and the first end portion of the underlying sheet to cause movement of the first end portion of the underlying sheet through the slot with the second end portion of the uppermost sheet to leave the first end portion of the underlying sheet projecting through the slot after the uppermost sheet is removed.

Title: Process and appliance for testing windings for short circuits
IPC: G01R31/72
Filed: 1990-02-05
Abstract: It is already known to induce a voltage into the coil to be tested (test specimen) by means of an exciter winding in an exciter circuit, the stray field generated by a winding with shorted turns due to the short-circuit current flowing in it inducing a voltage in a measuring coil of a measuring circuit. In the prior art, either an auxiliary winding is required, to which a calibration device is connected which is adjustable with respect to the phase angle of the current emitted, or the indicating device itself must be phase-sensitive. In both cases, a sufficiently accurate measurement is possible only at low frequency. According to the invention, the measurement is carried out at such a variable frequency that the voltage is a minimum when the test specimen is faultless. In the associated device, having a first limb-type core with an exciter winding and a second limb-type core with a measuring winding, and an indicating device connected thereto in an arrangement such that the limbs of the two limb-type cores can be encircled by the winding to be tested (test specimen), the limb- type cores (10, 20, 40) and the yokes (11, 21, 41) closing them consist of ferrite and an air gap (12, 22, 42) is formed between the limb-type cores (10, 20, 40) and the yoke (11, 21, 41) closing them in each case.

Title: Method for determining dynamic flow characteristics of multiphase flows
IPC: E21B47/10
Filed: 1990-05-16
Abstract: The present invention relates to a method for determining at least one 
dynamic flow characteristic of a multiphase flow circulating in a pipe, 
said flow being composed of at least a lighter dispersed-phase and a 
heavier continuous-phase. A tracer is discharged (or activated) into the 
flow at a chosen first location in the pipe by mixing (or activating) at 
least a portion of the tracer with the continuous-phase therein. The 
tracer concentration at at least a chosen second location in the pipe is 
measured with a detector as a function of time t, so as to obtain at least 
one signal S(t). Then a relationship is fitted to the signal S(t) so as 
to derive the values of the velocity U of the continuous phase and/or of a 
dispersion coefficient k. The slip velocity v s  of the dispersed phase 
relative to the velocity of the continuous phase is also advantageously 
determined.  
     From the values of velocities U and v s  and from the volume fraction 
y l  of the continuous phase in the pipe (obtained by an ancillary 
measurement), the volumetric flow rates of the continuous and dispsersed 
phases are determined.
