Title: Process for sanitary cleaning and a sanitary cleaner
Inventor: BECKER KLAUS
IPC: C11D3/32
Filed: 1994-05-20
Abstract: 2140548 9428100 PCTABS00034 The description relates to a process for sanitary cleaning with a sanitary cleaner in liquid or solid form containing germicidal organic substances in a quantity of at least some '.5 g/kg sanitary cleaner, conventional scale-removing water-soluble acids, germ-conveying organic materials resistant to the scale-removing water-soluble acids in a quantity of at least 10 mg/kg sanitary cleaner and possibly other additives. After dilution or washing, the action of the germs decomposing the organic substance in the water is promoted. As germ-conveying organic substance, the sanitary cleaner contains a compound of the formula (I): R1R2N-CO-NR3R4 in which R1 to R4 are mutually independently open-chained or cyclised and may be: hydrogen, a lower alkyl group with 1 to 4 carbon atoms, a cyclo-alkyl group with 3 to 6 carbon atoms, an aryl group in the form of a phenyl or naphthyl rest, an aralkyl group with 7 to 18 carbon atoms, an alkylaryl group with 7 to 18 carbon atoms or an O, S or N-containing heterocyclic group with 2 to 5 carbon atoms. This process and the sanitary cleaner used therein promote the respiratory activity of microflora in the communal waste water. This also results in the desirable germicidal function in the initial operating phase of a sanitary cleaner, e.g. in a toilet pan.

Title: Level Indication System
Inventor: JORDAN CHRIS A
IPC: G01F23/24
Filed: 1995-03-02
Abstract: A system for monitoring the water level of a pressure drum  having  a  pressure  column  comprises  a  plurality of electrodes communicating with the column for contacting water and steam within the column.   Each electrode has its own location and produces a first output which corresponds to the presence of water or a second output which corresponds to the presence of steam.  A discriminator is operatively connected to the electrodes; and the discriminator has an analog-to-digital converter for receiving the output of each electrode and converting the output to a digital signal which represents the  water  conductivity  for  each  electrode.    A  central processor is operatively connected to the discriminator for powering the discriminator as well  as  for receiving the digital signals in order to determine a slope degradation between the conductivity and the location of each electrode in the  column.    The  central  processor also  determines  an inflection point between the water and the  steam in the column.   An LED display is used to indicate which of the electrodes are located in water and which of the electrodes are located in steam.

Title: Method and an installation for dehydrating liquid effluent by composting
Inventor: PEULTIER PHILIPPE
IPC: C05F17/02
Filed: 1995-05-19
Abstract: The liquid effluent dehydration method is particularly suitable for effluent having low dry matter content and consists in distributing the liquid effluent in the form of a regulated drip feed throughout a composting substrate comprising a porous and carbon-containing medium disposed inside a reactor.  The method also consists in causing a flow of air to circulate through the medium in order to perform a fermentation reaction on the substrate and to remove the gases produced thereby, and in particular water vapor, by entraining them in the flow of air.  The liquid effluent feed rate is preferably regulated as a function of the moisture content of the substrate, in particular so as to maintain it in the range 40% to 80%, and the air flow rate is preferably regulated as a function of the temperature of the substrate, in particular so as to keep it in the range 55C to 65C.

IPC: H04M1/663
Filed: 1994-08-04
Abstract: The unit is connected between a user's telephone and a telephone exchange providing calling party identi-fication, such as calling number or name. The unit has user accessible audio inputs, either a microphone or an interface to a handset of the telephone. The unit also has audio message memory, a user programmable table of concordance for tracking the location of audio messages, a record/playback device, a speaker, and a controller. The unit may also have a visual display. Control keys may be connected to the controller, however their function may also be performed by using a keypad of the telephone. A speech generator may also be connected to the controller and to the speaker. In operation, the unit has program-ming, review, and monitoring modes. In the monitoring mode, the unit recognizes the number of a calling party (decoded from calling number delivery, call display or similar network-to-terminal signals on phone lines) by re-viewing the table of concordance, finds the appropriate message for that number and plays aloud the message stored for that calling party's number either through the speaker or the handset. The unit also stores information about the call for later recovery, possibly from a remote location. In programming mode, the control keys are used to prepare the unit to receive audio messages from the microphone or handset. The unit stores the messages and programs the table of concordance.

Title: Container self-sealing closing process
Inventor: LOHR CHRISTOPH
IPC: B65B7/16
Filed: 1995-02-06
Abstract: By covering humidity-sensitive meltable masses with an insertion that consists of a thermally stable and water vapour-tight plastic foil (1) and of a plastic disk (2) made of a thermoplastic material with a linear coefficient of expansion of at least 6.10-5/K, the surface of said meltable masses (6) may be self-sealingly closed. The meltable mass is reliably protected by this self-sealing closure against the penetration of humidity, even after a long storage. Thus closed containers with humidity-sensitive meltable masses may thus be stored for a long time.
