Title: Method and apparatus for optical signal analysis using a gated modulation source and an optical delay circuit to achieve a self-homodyne receiver
IPC: G01J9/04
Filed: 1989-01-20
Abstract: To observe the spectrum of an optical signal (12) it is 
selectively modulated (14) between an unmodulated and a 
modulated state, routed to an optical conduit (24) in 
parallel with an optical delay line (26) the two 
states thus being mixed together, the unmodulated state 
of the optical signal serving as a local oscillator 
signal. The parallel combination of the optical conduit 
and the optical delay line together with a photodetector 
(30) functions as a self-homodyne receiver. The self-­
homodyned mixing of the unmodulated and modulated states 
of the optical signal produced by the optical source 
serves to frequency-translate the optical power spectrum 
to within the bandwith of an analyzer (32) such as a 
microwave spectrum analyzer

Title: Production of preforms for blow molded articles
IPC: B29C49/06
Filed: 1989-03-22
Abstract: A plurality of injection cores (50) are inserted by a movable 
platen (20) into corresponding injection cavities (30) defined by mold 
inserts (28) within a stationary platen (18), and the cores extend 
through corresponding split transfer mold cavities (102). After hollow 
preforms (175) with threaded neck portions (176) are molded within the 
cavities, the preforms are removed from the mold cavities, separated from 
the injection cores, and then shifted transversely by the split transfer 
molds (100) to cooling or blow cavities (40) defined by blow cavity 
inserts (38) within the stationary platen on opposite sides of the 
corresponding injection cavities. The transfer molds return to receive 
the injection cores, and corresponding blow core units (60) are inserted 
into the preforms within the blow cavities for pressurizing and expanding 
the preforms into firm contact with the blow inserts. The preforms are 
removed from the blow cavities by the blow cores on alternate cycles of 
press operation and are then released by retraction of the blow cores. 
The split transfer molds are shifted transversely in opposite directions 
and are opened and closed by a cam system (115, 152, 158) which includes 
cam tracks (117, 118, 121) mounted on the movable platen and 
incorporating cam track switches (122).

Patent EP-0382327-A3 (EP)
Title: Arc spinner interrupter
IPC: H01H33/18
Filed: 1990-02-08
Abstract: An arc spinner interrupter includes a first 
fixed electrical contact and a ring electrode coupled to 
the fixed contact through a field coil surrounding the 
ring electrode. A second electrical contact has an arm 
which moves along a path perpendicular to the central 
longitudinal axis for selective connection with the fixed 
contact. The arm may have a generally L-shaped configur­
ation including an angled portion that extends in a 
direction parallel to the central longitudinal axis and a 
conductor extends toward the angled portion through the 
ring electrode along the central longitudinal axis. The 
conductor has an inner axial end that is spaced slightly 
from the angled portion of the arm when the arm is moved 
to a position intersecting the central longitudinal axis 
so that a grading function is carried out on the electro­
static field surrounding the angled portion of the arm. 
This grading function serves to limit the stress exerted 
by the electrostatic field adjacent the angled portion of 
the arm section. Further, the presence of the conductor 
within the ring electrode reduces the wear to the angled 
portion by permitting transfer of an arc from the angled 
portion during an interruption operation such that heat 
from the arc is distributed in the conductor rather than 
in the angled portion. During movement of the second 
contact away from the fixed contact, electromagnetic 
forces are simultaneously exerted on the arc due to the 
general L-shape of the arm of the second contact and move 
the arc material both toward the ring electrode and in 
the direction in which the arc spins once it has commuted 
to the ring electrode.

derived from an object (1) under servo control; a speed 
error detection circuit (3) for generating an error 
signal (ΔV) representing an error between a target speed 
(Vc) and the real speed (Vr); a position error detection 
circuit (4) for generating a position error signal (ΔP) 
from the position signal (Ps); a switching unit (5) for 
switching connection of the servo object (1) to the speed 
error detection circuit (3) or to the position error 
detection circuit (4); and a main processing unit (6) for 
controlling the switching of the switching unit (5). 
Near the target position, speed control by the speed 
error detection circuit (3) is switched to position 
control by the position error detection circuit (4). The 
main processing unit (6) measures the intervals between 
the position signals (ps) and based on the measured value 
changes the detection gain of a speed detection gain 
adjustment unit (2a) in the speed detection circuit (2).

Title: Boiler
IPC: F24H1/28
Filed: 1990-06-22
Abstract: A heating boiler comprises a heat-exchange chamber (13) surrounded by a heating jacket (15). Another water jacket (27) arranged concentrically with the latter extends, at the rear of the heating boiler, over approximately half the length of the heating jacket (15). A concentric core body (43) is located inside the water jacket (27). Helical flue gas channels (54, 56) each provided with an outlet (33, 37, respectively), are arranged in the spaces (53, 55, respectively. A flue gas flap (39) is located in the opening region of the outlets (33, 37). In the central  position illustrated, the flue gases can escape virtually unhindered from both flue gas channels. This corresponds to full-load operation of the burner (11). At minimal load, the outlet (33) is closed by the flue gas flap. In both cases, however, the flue gas temperature is the same. This prevents the temperature in every part of the heating boiler from descending below the dew point.
