Patent DE-19602388-A1 (DE)
Title: Temperature control method for central heating for room
Inventor: SCHELLE RALPH
IPC: F24D19/10
Filed: 1996-01-24
Abstract: The method involves room (1) heated by the hot water radiator (2) supplied from a central installation via the water inlet (3,5), return outlet (6) and thermostatic hand-operated valve (4). It employs an auxiliary electric heater in good thermal contact with the valve control thermostats. An overall system regulator (11) receives signals from a frost-protection room thermostat (17), a timer-programmer unit (15) and an infra-red pressure/movement sensor which combine to minimise unnecessary operating costs. The central installation water temperature conforms statutorily to outside ambient and temperature compensation within the room is achieved by energising through electric lead (9) the auxiliary heater to modify the valve throughflow.

Patent DE-19644944-A1 (DE)
Inventor: NERGER REINHARD DIPL ING
IPC: B65H5/10
Filed: 1996-10-29
Abstract: The invention relates to a device for feeding sheets from a sheet pile to a sheet conveyor drum of a printing machine. The invention seeks to create a device to feed sheets with high feeding performance and low dynamic load. According to the invention, this is performed in that a conveyor element is placed above the sheet pile, configured as a suction box and connected to a lever mechanism, grabs the respective top sheet on the sheet pile, separates the sheet from the sheet pile and conveys the sheet across a feed table to lay marks; and in that, underneath the plane of the feed table, a pre-gripper, configured as an oscillating suction element, grabs the sheet to be conveyed, accelerates its conveyance and delivers the sheet to the sheet conveyer drum.

Title: System for controlling heating unit of exhaust monitor in IC engine
Inventor: ABE SHINICHI
IPC: F02D41/14
Filed: 1997-06-24
Abstract: A system for controlling the heating unit (112) of an air/fuel sensor (11) monitoring the exhaust circuit (107) of an IC engine (10) is structured via the controller (13) to prevent the development of excessive temperatures after the sensor has been brought to its working point and activated. After starting, the heating unit (112) is energised continuously from its power source (12) at a primary rate designed to stabilise at 1100 degrees Celsius which equates to 710 degrees Celsius at the sensor element itself (111). When sensor (11) activation is established the subsequent input of electrical energy is reduced to an auxiliary level dependent on cooling water temperature (142) in order to prevent damage to the heating unit (112).

Title: Electronic pressure difference converter for washing machines, dishwashers
Inventor: SIVIERO DAMIANO
IPC: G01L9/00
Filed: 1997-10-16
Abstract: The converter for household washing appliances consists of a rigid hollow housing (2,3,4) within which a membrane (5) separates the space into two sealed chambers (6,7).
