Abstract: The invention relates to an appliance for washing webs of material guided spread out, in which the webs of material are guided past the circumference of rotating material guide drums with horizontal axes so as to bear against spray tubes arranged around the circumference of the drum and are subjected to the washing fluid. Its object is to achieve an effective washing capacity and a better utilisation of the washing fluid, whilst at the same time ensuring a minimum use of this. For this, according to the invention, the material guide drums are designed as perforated drums with closed side discs, in which the feed of the web of material takes place on the upper part of the drum circumference and its removal, after the rotation of the lower part of the drum, likewise takes place on the upper part of the drum circumference, and the spray tubes are arranged essentially in the lateral regions about the horizontal around the drum circumference. <IMAGE>

Inventor: BERNHARD DENNIS PATRICK
IPC: F25J3/08
Filed: 1988-04-21
Abstract: The present invention relates to a process for the recovery of ethylene from a feed gas (10) containing ethane, methane and other light gases, e.g. cracked gas or refinery off-gases, wherein ethylene is condensed in two stages (12, 20), preferably rectified (20), and fed to an integrated demethanizer column (62). Refrigeration for the process is provided by an integrated combination of work expansion (28) of rejected light gases, by vaporization of separated ethane at low partial pressure but high total pressure, and by a mixed refrigerant system (130, 132, 133, 134, 136). The process results in the separation and purification of ethylene from the feed gas stream while significantly reducing the energy consumption to do so.

Inventor: NOE REINHOLD DIPL-ING
IPC: G02F2/00
Filed: 1988-07-07
Abstract: In an optical heterodyne receiver, received light is heterodyned with the light generated by a local laser. A precondition of the heterodyning is the identical polarisation of the two light waves. Since the polarisation of the light transmitted via optical waveguides can change, automatic control of polarisation is necessary, and this has previously required at least three birefringent elements. In order to reduce the complication, use is made according to the invention of an integrated optical birefringent element in which there are arranged on an electro-optical substrate parallel to an optical waveguide arranged in the substrate three electrodes on the substrate surface to which specific voltages are applied. In order to correct manufacturing tolerances, it is possible to mount on the electro-optical substrate a correction element which has the same structure as the first birefringent element. <IMAGE>

Abstract: The present invention discloses a cartridge (1) for expelling liquids under high pressure. To this end, the cartridge (1) has as essential constructional element a sabot (4) which is arranged axially between a propellant-charge chamber (2) and a liquid chamber (3). Attached by positive or non-positive connection to the plane end face (7) of the sabot (4) is a closing element (21) which is separated axially from the sabot (4) by means of the pressure of the liquid flowing into the liquid chamber (3) and which is displaced forwards towards the barrel muzzle. Both the sabot (4) and the closing element (21) lie sealingly against the inner walls of the barrel (15) and the cartridge case (13) respectively. When the propellant charge (27) is ignited, the sabot (4) drives a water column, together with the closing element (21), into drill holes of a roadway core of a roadway drivage and thereby causes the rock of the roadway core to be comminuted.

Abstract: A temperature control system for a superheater of a drum or separator type fossil fuel fired steam generator develops a feed forward signal (F 2c ) that continuously adapts itself to changes in system variables to adjust the enthalpy (h₃) of the steam entering the superheater to change the heat absorption therein in accordance with changes in system variables to thereby maintain a substantially constant enthalpy (h₄) of the steam discharged from the superheater. The system develops (27,31) a feedback signal responsive to changes in the temperature (T₄) of the steam discharged from the superheater (1) to readjust the enthalpy (h₃) of the steam entering the superheater as required to maintain the temperature (T₄) of the steam discharged from the superheater at a predetermined set point value (29).

Abstract: A process for increasing the rate of plant growth. Plants are treated with one or more acids, which are condensation products of glycolic and/or L-lactic acid. These acids also increase the concentration of chlorophyll, increase the rate of new plant formation when plants are propagated by tissue culture, decrease the amount of added nutrients required for plant growth, and protect plants against the toxic effects of salts. Certain of the acids are useful for increasing the rate of root formation in the plant. +RR The questions raised in reexamination request Nos. 90/002,306, filed Mar. 26, 1991 and 90/003,035 filed Apr. 27, 1993, have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1.570(e).

Title: Decoupling network and communication system
Inventor: COOMER RONALD JAMES
IPC: H02J13/00
Filed: 1988-10-17
Abstract: A decoupling network for blocking high frequency 
communication signals on power lines. The network includes a 
filter having a first series element (10) for connection to a power 
line, a second series element (11) for connection to the 
same or another power line, and a shunt element (12) connected 
between the series elements and across two power lines. 
The shunt element acts as a short circuit to high frequency 
signals, thereby blocking passages of communication signals 
through the network. In one embodiment, a signal processing 
circuit (13) is inductively coupled to the series elements for 
processing communication signals from the supply authority 
and from consumers. The network prevents the communica­
tion signals from passing directly from the supply authority 
to the consumers, or vice versa.

Abstract: The two parts (10, 11) of the box hinge are connected releasably to one another, that is to say the hinge pin (16) of one part (10) and the hollow cylinder (17) of the other part (11) can be disengaged by axial displacement. Furthermore, the hinge pin (16) is mounted on the associated hinge part (10) so as to be rotatable and axially displaceable and is resiliently prestressed axially. At its free end, it is equipped with a rotation prevention means (38) which is engaged with the other hinge part (11) fixedly in terms of rotation and axially releasably. During the opening and closing of the particular box, the hinge pin (16) thus positively executes a rotational movement. In its portion located on the same side as the bearing, the hinge pin (16) is equipped with a radial grooved dowel pin (24) which at a predetermined angle engages as a result of spring force into a bearing notch (22) and thus locks the two hinge parts (10, 11) releasably at a predetermined opening angle.
