Title: Fremgangsmate for temperaturregulering ved satsvis lesking av brent kalk i en lesker
Inventor: STEPHANSEN POJU R
IPC: C04B2/04
Filed: 2010-09-13
Abstract: Det omtales en fremgangsmåte for satsvis lesking av brent kalk i en lesker (2), hvori det produseres kalkslurry med større finhetsgrad og forlenget sedimenteringstid, omfattende de følgende prosesstrinn: - uttømming av ferdiglesket og fortynnet kalkslurry fra leskeren (2), til det er en forutbestemt slurryvektmengde igjen, som brukes for blanding med neste sats; - automatisk innkopling av et styresystem for automatisk drift etter oppnådd ønsket leskingstemperatur av første sats, som tilsetter fortynningsvann og deretter brent kalk i en forutbestemt vektmengde i etterfølgende trinn; - automatisk regulering av leskingstemperaturen i neste slurrysats, hvor forholdet mellom vann og kalk justeres dersom den ønskete leskingstemperatur ikke var nådd i forrige sats, eller forbigått, og hvor leskeren (2) fylles fullstendig med vann for avbryting av leskingen dersom gitt maksimaltemperatur overstiges; og - automatisk registrering av leskerens gjenværende slurryvektmengde etter ferdig dosering av kalk, og etterfølgende tarering av et veiecelleaggregat (7) til O kg, før neste lesking. Regulering av leskingstemperaturen utføres avhengig av temperatur i leskeren, hvori: - ved temperatur under en forhåndsbestemt nedre grense reguleres temperaturen ved at tilførsel av kalk økes med en bestemt mengde kalk til lesketemperaturen ligger innenfor et forhåndsbestemt temperaturområde, og - ved temperatur over en forhåndsbestemt øvre grense reguleres temperaturen ved at tilførsel av kalk reduseres med en bestemt mengde kalk til lesketemperaturen ligger innenfor et forhåndsbestemt temperaturområde.

Title: System med et skifteverktøy ført av en ståltråd
Inventor: XU YANG
IPC: E21B23/06
Filed: 2011-10-07
Abstract: Et skifteverktøy blir kjørt på ståltråd og har en integrert kraftforsyning. Roterende bevegelse av motoren blir konvertert til rettlinjet bevegelse av skifteverktøyet ved hjelp av en kuleskrueanordning. Grepet oppnås med aksiell bevegelse av en gripeforbindelse, og et integrert slagverktøy kan utføre omkoblingen. Alternativt kan en lineærmotor bli anvendt for å strekke ut og trekke inn gripeenheten og omkoble ved hjelp av slagverktøyet. Eventuelt kan verktøyet bli forankret og rettlinjet bevegelse som følge av at den integrerte kraftkilden aktiviserer en motor kan sørge for omkoblingen.

Title: Method and reactor for the non-thermal decomposition and pasteurisation of organic process materials by electroporation
Inventor: SCHULTHEISS CHRISTOPH
IPC: A23L13/70
Filed: 2002-08-21
Abstract: In a reaction chamber, which constitutes a component of a process installation for obtaining foodstuffs or foodstuff components, biological products in harvested form that are whole or in pieces are subjected to pulsed electric fields as they pass through said reaction chamber, said electric fields forming pores in the cell walls so as to irreversibly open the latter, thus making the content of the cells more easily accessible. This is achieved by electrode groups, which can be energized to a high voltage and are located in the wall of a longitudinal passage of the reactor through which the process material is moved past grounded electrodes located in an opposing longitudinal wall area. Each electrode group is connected to an electric energy accumulator such as for example, a Marx generator, by means of a switch, in order to rapidly establish electric fields of multiple directions between the charged and the grounded electrodes.
