Patent DE-19546489-A1 (DE)
Inventor: HECKT ROMAN DIPL ING
IPC: F28F9/00
Filed: 1995-12-13
Abstract: The invention pertains to a heat-exchanger intended in particular for use in heat-generating and cooling machines which use the regenerative gas cycle process with separation of the heat exchange mediums. A pipe (1) with ribs (2) to increase the heat-exchange surface area serves as the flow channel for the heat-absorbing or heat-releasing, preferably liquid, heat carrying medium. The invention also pertains to a process for manufacturing a heat exchanger of this type. In order to produce a heat exchanger which is compact in volume and has a very small hydraulic diameter for the heat-releasing medium, the ribs (2) on the outer side surface (1a) of the pipe (1) are provided on their top parts (2a) with an impermeable and thermally insulating covering (5), and at least one flow channel is provided between the covering (5) and the outer side surface (1a) of the pipe (1) for the second heat-exchange medium which is formed preferably by a process gas.

Title: Intruder movement detection for surveillance and alarm system
Inventor: GIESELMANN CHRISTIAN
IPC: G06T7/254
Filed: 1996-02-02
Abstract: The method involves using video cameras to monitor a specific area. The camera outputs are switched to a converter to provide an input to a processing unit that controls the output section, such as sirens and lighting.  The images generated by the cameras are divided into specific sectors (17) and for each sector an average value for the brightness and/or colour is established.  The average values are compared with a predetermined value.  A pre alarm is generated if the reference is exceeded and a further comparison is made using a reference based upon a segment having an individual image (27) included.  When a change occurs the full alarm is triggered.
Patent DE-19605505-A1 (DE)
Title: Optical scanning arrangement for bar codes of any orientation
Inventor: FETZER GUENTER
IPC: G06K7/10
Filed: 1996-02-14
Abstract: The scanner employs a beam (4) of visible, ultraviolet or infrared radiation. It is emitted with a horizontal sweep (6a) which is directed at a diameter (5a) of the entry face (2) of a rotary cylinder (10). The rotation causes multiple reflection or refraction of the beam. The beam emerges from the exit face (13) in a plane (6b) undergoing continuous or stepwise rotation. The plane intersects that of the bar code (32) in a line (5b) which rotates across it four times during each revolution of the cylinder. The cylinder may be integrated into a hollow-axis motor.

Patent DE-19620647-A1 (DE)
Title: Reversing roll stand
Inventor: MAENO ICHIRO
IPC: B21B29/00
Filed: 1996-05-22
Abstract: Reversing roll stand is claimed where the work rolls (1, 1a) are driven by the support rolls (2, 2a) and end support rolls (4, 5) act on the ends of the work rolls outside the width of the strip being rolled. During the change of roll direction, devices (8, 8a, 9, 9a) are activated to move the support rolls w.r.t. the work rolls by an amt. This moves the support rolls to the left and the work rolls to the right. When the rolling re-starts in the opposite direction, adjustment devices (6, 6a, 10, 10a) act on the work rolls to even out any non-equilibrium horizontal forces.

Title: Exhaust gas purification system for internal combustion engine
Inventor: WEINOWSKI ROLF
IPC: F01N3/22
Filed: 1996-10-18
Abstract: The system minimises emission of hydrocarbon compounds, carbon monoxide and nitrogen oxides in the exhaust of an Otto engine. Fresh air is introduced into the exhaust system via a pump (10). The air flows via a pipe (11) with branches which enter the exhaust pipe (5,6) just downstream of the exhaust valve. The exhaust gas-air mixture passes a  lambda  sensor, just before the catalytic converter (7) which measures the proportion of oxygen in the exhaust gases. The lambda  sensor is connected to an engine control circuit (8) which is connected to the accelerator pedal (9) and the air pump. It controls the speed and the power of the engine and keeps the value of  lambda between 1.1 and 1.3.

Title: Image reconstruction method for medical computer tomographs
Inventor: FLOHR THOMAS DR
IPC: G06T5/00
Filed: 1997-03-21
Abstract: The Image reconstruction method involves using line detectors in a spiral operation. Inverse interpolation (rebinding) is carried out for folders on parallel data for all lines of the detectors independently. The parallel data are used for image reconstruction by weighting each beam. The weighting is dependent on the distance between the beam and the image surface.  The weighting is approximated by a Fourier series. The entire spectrum is provided by summing over all projection angles. Fourier reconstruction is used for a Cartesian frequency frame for inverse interpolation. The spectrum is then transformed back in the location region.
