Patent DE-4019159-A1 (DE)
Inventor: GONZE EUGENE VICTOR
IPC: F02D41/00
Filed: 1990-06-15
Abstract: A fuel control for an engine (11) of a motor vehicle using a liquid mixture of two fuels e.g. gasoline and methanol includes a fuel vapour collection canister open to the fuel tank and canister purge apparatus effective to allow fuel vapours to be drawn from the canister to the engine at a controlled purge rate during engine operation. The canister purge apparatus is responsive to a fuel composition sensor to vary a basic purge rate (CCP) as a function of the fuel composition (ALC %). When the two fuels are gasoline and methanol, the canister purge rate is varied, in a predetermined range of fuel temperature (FTS > TREF1), so as to provide a higher purge rate for mixtures of gasoline and methanol, in at least some proportions, than for either gasoline or methanol alone. The canister purge rate may further be varied in response to fuel temperature (FTS). The basic purge rate (CCP) is set as a function of air flow or manifold pressure. <IMAGE>

Title: Method of constructing outer wall of chimney - uses template to place mortar in required positions
Inventor: HEROLD EBERHARD
IPC: E04F21/04
Filed: 1991-01-29
Abstract: The chimney has its outer wall constructed from slabs (22). These slabs have flat outer surfaces and curved inner surfaces which match the contour of the inner wall. The slabs are placed in the required position with the aid of a template (10) which is placed on top of the first row of slabs. Mortar is then placed over that part of the slab end surfaces which is not covered by the template. The template is then removed and the next row of the slabs is put in place. This process is repeated until the chimney is at the height at which the chimney pot is to be added. At this stage the template is left in place to serve as shuttering for casting the chimney pot in situ. USE - Building of chimneys.

Title: Regulating heating in motor vehicle - providing proportional control for normal heating and direct control if outside temperatures differ by more than preset level
Inventor: WIESZT HERBERT DIPL ING
IPC: B60H1/00
Filed: 1991-07-18
Abstract: A vehicle heating control measures the temp. difference between the target temp. and the actual temp. to generate a correction signal for the heating. If the difference is negative, i.e. outside temp. of the vehicle is high, a different mode of control is used, with direct temp. control rather than proportional control. The switching between the two modes of control uses a simple logic addition to the control circuits. It provides an adaptable heating control with optimum confort for the occupants.

IPC: G06F1/00
Filed: 1991-08-13
Abstract: The keyboard input unit consists essentially of a conductor matrix, a keyboard with input keys for coupling mutually crossing conductors, and a control and evaluation circuit (P). In order to prevent spying on an operated key, in the original state, each conductor (A-H) is connected to an ideal source. A conductor interrogation takes place, for example, by connecting a conductor (A-H) to a load-dependent source. If this conductor (A-H) does not assume the value of the load-dependent source, then this conductor (A-H) is coupled at a crossing point (1-28) to another conductor (A-H) through a pressed key. Externally, the original state is simulated. Pressed and released keys are simulated in a similar manner. <IMAGE>
