Patent DE-3814238-A1 (DE)
Inventor: HOLZER WALTER DR
IPC: F25D21/04
Filed: 1988-04-27
Abstract: PCT No. PCT/EP89/00464 Sec. 371 Date Dec. 22, 1989 Sec. 102(e) Date Dec. 22, 1989 PCT Filed Apr. 27, 1989 PCT Pub. No. WO89/10523 PCT Pub. Date Nov. 2, 1989.According to this invention, cold is conveyed into a cooling chamber by means of convectors, and fresh air of a higher temperature is supplied in a controlled manner so that the temperature decreases. To avoid power loss due to the quantity of heat supplied, the displaced cold air is channeled towards a heat exchanger in the condenser of the cooling machine. Since the fresh air which circulates is always above 0 DEG  C., the humidity content of the fresh air supplied can be controlled and be filtered to remove odors.

Title: Television system with devices for adapting a television picture format generated at the transmitting end and at the receiving end
Inventor: KAYS RUEDIGER DR ING
IPC: H04N5/44
Filed: 1988-12-22
Abstract: For future television systems with increased picture quality, it is intended to change the picture aspect ratio from 4:3 to 16:9, and it is intended to reproduce signals with both picture aspect ratios in future television receivers. In a television receiver with electron beam tubes, the deflection has hitherto been switched over by the deflection processor for the relative change in television picture format. This requires a high circuit complexity in the television receiver. For the adaptation of the television picture format generated at the transmitting end and at the receiving end, the video signal is temporally transformed by means of a memory arranged in the video signal processor in a television receiver with changed picture aspect ratio, the visible part of the line being inserted time-compressed into the reproduction raster. Depending on the picture format generated at the transmitting end, the reproduction device can be additionally switched over in the vertical direction in the television receiver, the reproduction raster being unchanged in the horizontal direction. Future television systems with devices for compatibly changing the picture format.

Title: Ignition method for an atmospheric oil burner with an electrically operated ignition element
Inventor: STEINMANN HELMUT
IPC: F23Q7/08
Filed: 1989-01-21
Abstract: In order to make it possible for an atmospheric oil burner to be switched on again when the burner pot is (still) warm, e.g. shortly after the end of a previous combustion process, an ignition sequence which differs from that for the ignition of the oil burner when the burner pot is cold is initiated: when the burner pot is cold, the ignition sequence proceeds in principle in the order oil admission - ignition, whereas the ignition sequence when the burner pot is warm has the reverse order ignition - oil admission. The ignition sequence required in each case is triggered by a temperature sensor on the bottom of the burner pot.
