Title: Water sterilization system recirculating contents of vessel loosing heat, e.g. whirlpool bath, heats water to temperature killing harmful microbes
Inventor: LAING KARSTEN
IPC: A61H33/00
Filed: 1999-12-16
Abstract: Circulating water is heated to a temperature at which harmful microbes are killed.  Preferred features: The water flow is heated by an element (11) at the end of a counter flow heat exchanger (13, 14). The heated water flow transfers most of its heat to water entering. The pump remains switched off until sterilization temperature is reached in a vessel. Thereafter it is switched on until the content of this vessel is driven out, and it is then switched off. It is not switched on again, until the temperature in the vessel falls below a given level. A timer determines the interval. This shortens the interval in accordance with the heat demand of the vessel. The hollow vessel is a capsule surrounded by a ring clamped between two covers. The cover includes spiral grooves into which heat transfer strips project. The strips are made of organic material. One ends close to a heating element (11); the other reaches to it. The cover is held together by a rod (9) through the center. The heating element is eccentric to the ring. Ends of the strips near the periphery project into axi-parallel slots (5, 6). The counter flow heat exchanger is controlled by a float valve in the collection vessel and a valve opening only when the thermostat indicates achievement of sterilization temperature.

Patent EP-1033078-A1 (EP)
Inventor: BEHRMANN JOACHIM
IPC: A23K10/30
Filed: 2000-02-28
Abstract: Since milk production (or growth) is influenced principally by the conversion of starches, i.e. carbohydrates, into glucose in the small intestine the foodstuff is treated with water and steam. This forms a protein layer around the starch particles that protects them in the rumen but is digested by enzymes in the intestine.  The foodstuff is first reduced by a hammer-mill in stage 1 before passing into conditioning stage 2 where water and steam are added. The dwell time in this stage is between 10 and 120 sec. at a temperature of about 80 degrees C. At stage 3 a screw feed extrudes the feedstuff through a perforated plate at about 50 bar, producing heat mechanically which, when boosted by additional steam, raises the temperature to about 130 degrees C. The extrusions are then cooled in stage 5.

Abstract: The system includes use of a control call to determine the charge, prior to establishing full connection. The system provides tariff information for specific destinations and target terminals on a telecommunications network, to indicate to users the tariff applicable before establishing a connection.

For these purposes, the tariff informati is coded inside a normalised call control message which is transmitted to establish the connection, and is intended to be receiv by at least one of the terminals before establishing the connection. The tariff information may be encoded in an 'alerting' type message, or in a 'setup' type message, according to the GSM 04.80 standard, when destined for either the calling or the called number respectively.
Patent EP-1063694-A1 (EP)
Inventor: HERGENROTHER JOHN MICHAEL
IPC: H01L29/161
Filed: 2000-06-06
Abstract: A process for fabricating a vertical MOSFET device for use in
integrated circuits is disclosed. In the process, at least three layers of
material are formed sequentially on a semiconductor substrate. The three
layers are arranged such that the second layer is interposed between the
first and third layers. The second layer is sacrificial, that is, the layer is
completely removed during subsequent processing. The thickness of the
second layer defines the physical gate length of the vertical MOSFET. In the
process the first and third layers have etch rates that are significantly lower
than the etch rate of the second layer in an etchant selected to remove the
second layer. The top layer, which is either the third or subsequent layer, is
a stop layer for a subsequently performed mechanical polishing step that is
used to remove materials formed over the at least four layers. 
     After the at least three layers of material are formed on the substrate,
a window or trench is formed in the layers. The window terminates at the
surface of the silicon substrate in which one of either a source or drain region
is formed in the silicon substrate. The window or trench is then filled with a
semiconductor material. This semiconductor plug becomes the vertical
channel of the transistor. Therefore the crystalline semiconductor plug is
doped to form a source extension, a drain extension, and a channel region in
the plug. Subsequent processing forms the other of a source or drain on top
of the vertical channel and removes the sacrificial second material layer.
The removal of the sacrificial second layer exposes a portion of the doped
semiconductor plug. The device gate dielectric is then formed on the exposed
portion of the doped semiconductor plug. The gate electrode is then
deposited. The physical gate length of the resulting device corresponds to
the deposited thickness of the second material layer.
