Title: Electronic circuit to work out reference values
IPC: G05D23/24
Filed: 1981-10-01
Abstract: 1. An electric circuit for processing desired values, such as the heating curve (outdoor temperature), desired day and night temperatures and, if desired, desired external temperatures, comprising elements for detecting desired values and at least two final control elements, one of which connects and disconnects a heat pump and a fuel-heated or electrically heated heat source to and from a heat-receiving consumer whereas the second final control element controls the desired value for the heat pump which is in operation, characterized by a desired-value limiter (21), which at its inputs receives a change-over value, which depends on the outdoor temperature, and a correcting change-over value, which corresponds to all desired-value detectors (desired values for day and night temperatures and external heating curve), whereas its output is connected to the final control elements (102, 108, 113, 119 and 124), one (102) of which comprises a change-over switch (25) for turning off the heat pump (WP) or the heat source (boiler) and the others (108, 113, 119 and 124) control merely the transmission of the desired-value signal to the controller for the heat pump or the controller for the heat source.

Patent EP-0075480-A3 (EP)
IPC: G06F13/00
Filed: 1982-09-21
Abstract: A serial data communication system comprises digital 
send/receive logic 103 and analog send/receive circuitry 
104. Data is transmitted over a bus 105, encoded as no pulse 
for a ONE, alternate positive and negative pulses for succes­
sive ZERO's. For transmitting, circuitry 103 includes a tim­
ing flip-flop which produces a ³/⁴-bit-period STROBE signal 
for each ZERO, and a toggle flip-flop for pulse polarity. For 
receiving, incoming positive and negative pulses drive sepa­
rate digital differentiators. A synchronizing counter is con­
trolled to include an extra «tick» or omit a tick from a normal 
16-tick bit period appropriately. A further counter detects a 
string of at elast 8 ONE's, representing the end of transmis­
sion, the data being pre-coded to ensure that such a string 
of ONE's cannot occur in true transmission of information.

Abstract: Electrodes of a high power, microwave field effect transistor 
are substantially matched to external input and output networks. The 
field effect transistor includes a metal ground plane layer, a 
dielectric layer on the ground plane layer, a gallium arsenide 
active region on the dielectric layer, and substantially coplanar 
spaced source, gate and drain electrodes having active segments 
covering the active region. The active segment of the gate electrode 
is located between edges of the active segment of the source 
electrodes. The gate and drain electrodes include inactive pads 
remote from the active segments thereof. The pads are connected 
directly to the input and output networks. The source electrode is 
connected to the ground plane layer. The space between the 
electrodes and the geometry of the electrodes establish parasitic 
shunt capacitances and series inductances that provide substantial 
matches between the input network and the gate electrode and between 
the output network and the drain electrode. Many of the devices are 
connected in parallel and share a common active region, so that each 
pair of adjacent devices shares the same source electrodes and each 
pair of adjacent devices shares the same drain electrodes. The gate 
electrodes for the parallel devices are formed by a continuous 
stripe that extends between adjacent devices and is connected at 
different points to the common gate pad.

Abstract: In an exemplary embodiment, a slide selectively closes the upper end of the connecting tube. The dispatch tube and the receiving opening are offset relative to one another in such manner that, at the moment a pneumatic traveler is transferred out of the receiving opening, a mechanical restraining device of the dispatch tube is not yet actuated. The pneumatic dispatch station can be employed as a dispatch station with a dispatch ready position for an outgoing pneumatic traveler, as a receiving station and as a transit station with the use of only a single connecting tube movable to three positions therein. The three positions may be separated by less than two diameters of the tube.

IPC: B25J11/00
Filed: 1983-05-27
Abstract: A powered, electromechanical manipulator assembly is disclosed which includes an electrically powered input device (21) coupled by a hydraulic circuit (29) to a mechanical manipulator. The hydraulic circuit (29) is a fixed-volume, closed circuit in which a master piston-cylinder assembly (32) is driven by a D.C. motor (26) and a hydraulically coupled for direct and proportional displacement of a slave piston-cylinder assembly (33) to enable smooth, accurate and easily controlled displacement of a manipulator arm (61). The manipulator arm (61) is formed of a plurality of modules (62a, 62b, 62c, 62d) each having a fixed- volume, closed, hydraulic circuit (29) and a slave cylinder (33). Both the slave and master cylinders include ambient pressure surfaces (53,54) which are exposed to the water pressure at the operating depth of the assembly so that variation in depth does not materially affect the response or dexterity of the remote manipulator apparatus.

Abstract: A carton opening mechanism for use in opening knock­
ed-down cartons. The carton opening mechanism has a 
carton storage magazine which has a discharge opening 
through which knocked-down cartons may be withdrawn 
one at a time. The carton opening mechanism has a first 
suction face which is circumferentially spaced 120 degrees 
from the discharge opening of the magazine. The carton 
opening mechanism is mountable in a carton opening 
machine so as to locate the receiver compartment equidis­

the entranceway of a receiving compartment opening to­
ward a central axis. A rotary transfer mechanism is mounted 
for rotation about the central axis, the transfer mechanism 
having a suction head formed with a transfer suction face. 
The transfer suction face is movable, in response to rotation 
of said transfer mechanism, between, a first position in 
which the transfer suction face is directed toward said 
discharge opening and positioned to engage a wall of a 
carton blank located in the storage magazine and, a second 
position in which the transfer suction face is directed toward 
and disposed opposite the first suction face of a carton 
opening mechanism to press an opposite wall of the carton 
into engagement with the first suction face, and, a third 
position in which the transfer suction face is directed toward 
and disposed adjacent the entranceway of the receiver to 
deposit an open carton in a receiver compartment. The 
transfer mechanism then returns to the first position. A 
suction control mechanism is provided to generate a nega­
tive pressure at said transfer suction face when it is in said 
first position and during movement of the transfer suction 
face between said first, second and third positions so as to 
secure a wall of a knocked-down carton thereto, withdraw it 
from the storage magazine, transport it to and open it by 
engagement with the opening suction cup of the opening 
mechanism and deposit the open carton in the receiver 
compartment and thereafter to relieve the negative pressure 
to release the open carton.

Abstract: A method of detecting the presence of an indicating device in a restricted investigation zone, comprising the detecting of an indicating device (31) of a highly permeable material by emitting and receiving a magnetic field, where two coils (1, 2) are caused to emit a high-frequency magnetic alternating field, and a first one of the coils (1) emits an alternating field with a frequency (f,) different from the fre- quence (f<sub>2</sub>) of the field emitted by the second one of the coils (2), and at least one difference and/or sum frequency n f<sub>1</sub> + m f. occurring by intermodulation by means of the indicating device (31), where n and m are positive or negative integers, is caused to be received by one or several coils (9). According to the invention, a third low-frequency magnetic alternating field is caused to be emitted in said zone with a frequency (f,) substantially lower than the frequencies (f<sub>1</sub>, f<sub>2</sub>), which low-frequency field is caused to have a field intensity sufficiently high, independently of the fields with the frequencies (f,) and (f<sub>2</sub>) to put the indicating device (31) into saturated condition in step with the frequency of the low-frequency field. A filed re-emitted from the indicating device (31) hereby is detected by means of a detector device as an intermodulation occurring periodically with the frequency of the low-frequency field between the frequencies (f,) and (f<sub>2</sub>).
