Abstract: Zur Verringerung des Verschleißes und Erhöhung des 
Füllungsgrades gegenüber herkömmlichen Zellenrad­
schleusen mit zylindrischen Rotoren, ist hierbei 
der Rotor kugelig mit schräg nach unten geneigter 
Welle angeordnet. Durch die kugelige Ausführungs­
form wird die mittlere Umfangageschwindigkeit des

Title: Electromagnetic relay having an improved terminal structure
IPC: H01H50/24
Filed: 1989-11-21
Abstract: An electromagnetic relay in which terminal pieces 
carrying fixed contact pieces can be assembled in the case for the 
electromagnetic relay from above. The case consists of a main case 
accommodating an electromagnet unit, a terminal case accommodating a 
contact unit and mounted on the main case, and a cover which is 
mounted on the terminal case. Each of the terminal pieces is fitted 
into a mounting position in a certain direction to be made immobile in 
any other direction perpendicular thereto. The cover is provided with 
a plurality of projections each of which engages with one of the 
terminal pieces to prevent it from moving in the said certain 
direction. Thus, the terminal pieces may be assembled from the upper 
end of the terminal case, and the work required for this assembly 
process may be significantly reduced. According to this structure, 
since the terminal case may be integrally provided with a bottom wall 
which separates the contact unit in the terminal case from the 
electromagnet unit accommodated in the main case, a better insulation 
can be achieved without in any way complicating the assembly process.

fraction (R(R+r)) of the base-emitter voltage of the first 
transistor (Q1) with a second, larger predetermined fraction (1) 
of the base-emitter voltage of the second transistor (Q2) so that 
an output (28) of the comparator adopts a first state when the 
temperature of the two devices is above a known threshold 
temperature and adopts a second state when the temperature of the 
two devices is below the known threshold temperature. The 
circuit is accurate and is compatible with MOS technology.

Title: Production of homoserine and its derivatives such as threonine derivatives and methionine precursors
IPC: C12R1/725
Filed: 1989-04-19
Abstract: The methionine salvage pathway which is 
normally used to produce polyamines using ATP as a 
carbon source, can provide significant amounts of 
homoserine for use in biosynthesis of threonine, 
threonine derivatives and methionine precursors. 
Specifically, a cell is engineered to produce 
S-adenosylmethionine hydrolase, thereby providing a 
synthetic route to the above compounds which avoids 
feedback regulation upstream of homoserine, and which 
relies on a carbon source (ATP) that is replenished as a 
priority.
Patent EP-0348100-A3 (EP)
Title: Phase jitter compensation arrangement using an adaptive iir filter
IPC: H03H17/04
Filed: 1989-06-15
Abstract: A voice-band data symbol is typically impaired by so-called 
phase jitter prior to the symbol being received at a data modem. Modem 
circuitry estimates the phase angle of the jitter and an infinite-impulse-­
response (IIR) filter adjusts to that phase angle so that the jitter can be 
corrected for by a demodulator circuit. Advantageously, the IIR filter is 
arranged so that its pair of complex, conjugate poles are initially positioned 
at a first predetermined radius within a unit circle. The angular 
displacement of the poles around the unit circle is adaptively increased in 
response to receipt of a series of such estimates until such displacement 
substantially equals the phase angle of the jitter. The poles are then 
positioned at a second predetermined radius to increase the gain of the 
filter.

Title: Method of manufacturing automobile windows
IPC: B29C70/76
Filed: 1989-11-10
Abstract: A method of manufacturing automobile windows 
including a window plate (2) and a frame member (3) provided 
integrally with the window plate and locally defining 
guide means (7) in the form of a ridge or channel for 
guiding rain water to flow along the frame member. 
In case of a front window, the guide means (7) extends along 
side regions of the frame member to prevent rain water 
from flowing across the frame member and to preserve the 
driver's sight through a neighbouring side window. 
The frame member is composed of a thermoplastic 
synthetic resin material containing a foamable agent, 
which is subjected to a dielectric heating in a mold (20) to 
cause the foamable agent to expand in the mold. 
The guide means may be prepared separately from a pre-shaped 
frame body (11) and then caused to adhere with each 
other in the mold, or may be formed integrally with the 
pre-shaped frame body which is then subjected to a local 
removal of material.

Patent EP-0397958-A3 (EP)
Title: Ultrasonic sensor with starved dilatational modes
IPC: B06B1/06
Filed: 1990-01-10
Abstract: A method and apparatus to improve the performance of an ultrasonic 
imaging sensor [11] is disclosed. The key to the performance improvement 
obtained in the present invention is in the matching of sensor element [10] size to 
the electrical characteristics of the train of pulses [24,32] used to drive the sensor. 
The matching causes essentially all the energy provided to the sensor [11] to go into 
the desired sensor resonances, those in the direction of the sensor's thickness 
dimension [12]. The matching also minimizes the energy which goes into the 
undesired dilatational resonance modes [16,18] those in the sensor element's width 
dimension [14]. The invention discloses the matching of each sensor element [10] 
so that its maximum dilatational response [54] is essentially at the same frequency 
as every other element in the array, so that dilatational response is substantially 
reduced for the array as a whole. The invention also discloses the "fine tuning" of 
the frequency of the drive pulses, so that the dilatational response is further 
reduced. The invention therefore permits the fabrication of ultrasonic sensor 
arrays [11], having high sensitivity, freedom from spurious returns, and low noise 
signals.
