Title: Aussenrückblickspiegel für fahrzeuge, insbesondere für kraftfahrzeuge
Inventor: APFELBECK ROBERT
IPC: B60Q1/26
Filed: 2003-02-14
Abstract: Um den Aussenrückblickspiegel (1) so auszubilden, dass auf einfache konstruktive Weise auch bei abgeklapptem Spiegelkopf (2) der Bereich neben dem Fahrzeug durch die Umfeldleuchte (6) einwandfrei ausgeleuchtet werden kann, ist diese in bezug auf den Spiegelkopfe (2) ortsfest angeordnet. Der Spiegelkopf (2) hat ferner eine Durchtrittsöffnung (18) für die von der Umfeldleuchte (6) ausgehenden Strahlen, da die Umfeldleuchte (6) in der Gebrauchslage und in der abgeklappten Lage ihre Lage unverän­dert beibehält.

Patent WO-2004025111-A1 (WO)
Title: Aggregat zum fördern von kraftstoff aus einem kraftstofftank zur brennkraftmaschine eines kraftfahrzeuges
Inventor: SCHELHAS PETER
IPC: F04B17/04
Filed: 2003-08-22
Abstract: Bei herkömmlichen Elektrokraftstoffpumpen wird der Kraftstoff direkt in ein Pumpenteil angesaugt, so dass ein Gehäuse und ein Elektromotor der Elektrokraftstoffpumpe stromab des Pumpenteils unter einem von dem Pumpenteil aufgebauten Druck stehen. Da heutige Elektrokraftstoffpumpen mit vergleichsweise hohen Drücken arbeiten, muss das Gehäuse stromab des Pumpenteils aufwendig abgedichtet werden. Bei dem erfindungsgemässen Aggregat wird die Anforderung an die Abdichtung des Gehäuses deutlich verringert, so dass die Herstellungskosten erheblich sinken. Erfindungsgemäss wird vorgeschlagen, einen Aktor (15) auf einer Saugseite (20) des Gehäuse (2) anzuordnen, so dass der Kraftstoff über einen EingangsanschluB (5) des Gehäuses (2) an dem Aktor (15) vorbei angesaugt wird. Da der Druckaufbau erst in dem Pumpenteil (14) erfolgt und der Kraftstoff anschliessend das Aggregat schon wieder über einen Ausgangsanschluss (9) verlässt, steht nur noch ein kleines Volumen des Aggregats unter einem vergleichsweise hohen Druck.

Title: Heat exchanger coil attachment to metallic - reaction vessel
Inventor: KUXDORF BERNHARD DIPL-ING
IPC: F28F1/14
Filed: 1970-01-02
Abstract: Heat exchange between the walls of a process vessel, esp. an evaporator and a tubular coil surrounding it is improved by connecting the coil to the outer walls of the vessel by continuous welded connections made from a metal having a high thermal conductivity. The method is used when the use of double walled heat exchangers would be dangerous in case of leakage between vessel and fluid in the outer wall, but where the thermal efficiency of the normal surface contact heat exchange cannot be tolerated.

Title: Clarifier for beer wort mash
IPC: C12C7/14
Filed: 1970-02-24
Abstract: Mash clarifier vat has a screen formed from a surface of rotation having slots in planes at right angles to the axis of the surface to lead wort to a central run-off, the slots cleaned out by rotary scavenger. The scavengers are carried on a common bar in the same plane as the surface axis and can be stationary while the slotted plate forming the screen rotates. The slots should expand in section radially at the outer end to clear grains and are arranged between a stack of plates leading to a central run-off tube with perforations and rise and fall cut-off plunger to force the wort out and drive purging water through the slots to clear them after wort removal. Clogging is avoided by continuously or intermittently rotating the scavengers and slots, and the grain cake forming in the plate slots is completely removed.

Title: Floor heating using hot water or air - has flow passages of linked channels adjacent to each other
Inventor: ENGEL THOMAS PAUL
IPC: F24D3/16
Filed: 1973-12-24
Abstract: A box structure is placed immediately below the finished floor surface. It has inlet and outlet connections for the heating medium which may be hot water or warm air, and is divided internally by vertical partitions into a series of channels.
