Title: Production d'olefines
Inventor: DATH JEAN-PIERRE
IPC: B01J29/40
Filed: 1998-12-07
Abstract: L'invention concerne un procédé de craquage catalytique d'une ou plusieurs oléfines, dans un flux oléfinique contenant des impuretés, le procédé de craquage étant sélectif vis à vis des oléfines légères de l'effluent. Ce procédé consiste à mettre en contact un flux oléfinique de charge d'alimentation contenant au moins une impureté dérivée du soufre, de l'azote et/ou de l'oxygène avec un catalyseur au silicate cristallisé de type MFI. Ce catalyseur présente un rapport atomique silicium/aluminium d'au moins environ 180, de manière à produire un flux d'effluent ayant sensiblement le même contenu oléfinique pondéral que le flux d'alimentation, mais ayant une distribution oléfinique différente.

Title: Method for biological purifying of waste waters from organic compounds and nitrogen
Inventor: KOGAN JURIJ A
IPC: C02F3/30
Filed: 1987-03-10
Abstract: This method is intended for application in the purification of waters from mineral fertilisers from animal breeding farms, as well as urban domestic sewage waters. The method provides reduction of the duration of the purification process, lower power consumption, and improved quality of the purified waters.  The method involves anaerobic treatment of water, which is continued until complete ammoniation of the organically bound nitrogen, while the aerobic treatment is conducted at a redox potential of 210 to 290 mV at an aerobic age of the active pallet ranging from 3 to 7 days.

Abstract: ZINC ANODES FOR ALKALINE GALVANIC CELLS, AND CELLS CONTAINING THEM          ABSTRACT OF THE INVENTION    An   alkaline  manganese  cell  -- which  is   generally   a rechargeable  cell,  but  which may also be a primary cell  -- is provided,  having an anode composition  where the anode comprises an  admixture  of  amalgamated zinc  particles,  zinc  oxide  and metallic copper.  The metallic copper is finely divided and has a large surface area,  so that the copper is distributed throughout the  anode and forms an electrically conductive,  low  resistance structure within the anode.  The metallic matrix within the anode takes the appearance of a sponge,  and provides for  conductivity within  the  anode at all stages of charge and discharge  of  the cell.  Especially in the anode of a secondary cell, the cell will exhibit  an  overcharge  reserve because there  is  a  sufficient amount  of zinc oxide in the anode,  and it will exhibit an  over discharge  reserve because of the presence of metallic copper  in the  anode.   Several  processes  for  preparation  of  the  zinc oxide/copper  mixture are discussed,  including several different chemical  and electro-chemical reactions which may  be  followed.          The preparation of the mix is exothermic,  and the mixture should be kept in such a manner as to preclude its exposure to oxygen.

Title: Self-powered base and remote telephone communication set
Inventor: PEDIGO MICHAEL K
IPC: H04B7/26
Filed: 1990-06-07
Abstract: ABSTRACT OF THE INVENTION    A cordless remote telephone unit communicates with a telephone line through a stationary self-powered base unit. The base unit is not plugged into an electrical household receptacle and is therefore completely portable to any location having a telephone jack.  The remote unit is portable to any location within the radio range of the base unit.  The base unit does not require a household electrical receptacle because non-rechargeable batteries are used in the base and remote units, so there is no need for a battery charger.  Moreover, power consumption is minimized when the system is idle by cycling the battery power in both the remote and base units.  As communication begins, continuous battery power is provided in place of the cycled power in the base unit in response to receiving from the remote unit a 5 KHz activation tone, a security code and a 22 Hz pilot tone, or in response to a ring received from the telephone line.  After communication is established between the two units, the base unit derives reliable power through its hook switch directly from the telephone line using a power regulator suited for the purpose, further reducing power demand on the batteries.  Power cycling in the remote unit is replaced by continuous battery power in response to receiving from the base unit a ring tone generated by the base unit ring detector, followed by a security code, or whenever the remote unit hand set is picked up by the user. In one embodiment of the invention, the remote unit and the is connected to a remote unit chassis by a cord, and the remote unit radio receiver and radio transmitter circuits use the cord as their antenna.

Abstract: ABSTRACT     An  apparatus  and  method  for  decreasing  the  memory requirements  of  BIOS  in  a  personal  computer  system includes storing a first portion of BIOS in memory and a second portion on a direct storage access device.   The personal computer system comprises a system processor, a random access main memory,  a read only memory,  and at least one direct access storage device.   The read only memory  includes  the  first  portion  of  BIOS  and  data representing  the  type  of  system  processor  and system planar I/O configuration.  The first portion of BIOS only includes  routines  for  initializing the  system and the direct access storage device to read in a master boot record into the system from the direct access storage device. The master boot record includes a data segment and  an  executable  code  segment.   The  data  segment includes data representing system hardware and a system configuration  which  is  supported  by  the  master  boot record.  The first BIOS portion confirms the master boot record  is  compatible  with  the  system hardware  by verifying that the data from the data segment of the master boot  record  agrees  with  the  system  processor, system planar,  and planar  I/O  configuration.   If  the master  boot  record  is  compatible  with  the  system hardware,  the  first  BIOS  portion  vectors  the  system processor to execute the executable code segment of the master boot record.  The executable code segment confirms that the system configuration has not changed and loads in the  remaining BIOS portion  from the direct  access storage device into random access memory superseding the first BIOS portion.   The  executable  code  segment then verifies the authenticity of the remaining BIOS portion and vectors the system processor to begin executing the remaining  BIOS  now  in  random  access  memory.   The remaining BIOS in main memory includes reusable routines for operating the personal computer system in a normal manner.

Title: Relay-controlled anticipation in a two switch thermostat
Inventor: JUNTUNEN ROBERT D
IPC: F24F11/76
Filed: 1991-03-08
Abstract: ABSTRACT OF THE DISCLOSURE    A conventional thermostat has separate high and low temperature switches for controlling a reversible motor driving a modulating damper or valve whose position controls the temperature of an enclosure by controlling the injection and removal of heat from the enclosure.  In the improvement, relay contacts control the current flow to the thermostat's heat and cool anticipator resistors, and only relay control current flows through the motor windings.  This avoids degraded motor performance resulting from anticipator resistor current flow through the motor windings and makes the anticipator resistor current level independent of the motor impedance.  The relay chosen is one whose activating control draws very little current to close the relay contacts.  The preferred embodiment uses a solid state relay which includes a light emitting diode whose light emissions control the impedance of a semiconductor circuit forming the "contacts" of the relay.
