Title: Level sensor with permanent magnet - pivotally mounted about vertical axis w.r.t. magnetically-operated switch
Inventor: KUEBLER HEINRICH DR
IPC: H01H36/02
Filed: 1989-05-30
Abstract: The permanent magnet is fixed to a probe (16) movable by the level-giving medium. An electrical switch (4) which can be operated by the magnet (6) is accommodated in a vertical pipe (2) fixed at its upper end and sealed by non-magnetisable material against the medium.

Title: In-tank fuel reservoir with reservoir fuel level control
Inventor: TUCKEY CHARLES HENRY
IPC: B60K15/077
Filed: 1989-12-28
Abstract: The fuel delivery system has a canister positioned within a fuel tank and has an open layer end and an internal wall spaced from the lower canister end for dividing the canister into upper and lower chambers. An electric fuel pump is carried by the canister wall within the upper chamber and has an inlet coupled through the wall to the lower chamber. The pump outlet feeds fuel under pressure to an engine, and excess fuel is returned to the upper chamber which thus forms a fuel reservoir.

Title: Direct generation of wait cycles for electronic equipment - communicating with slower devices involves converting address signal directly into number of wait cycles
Inventor: SCHEMITZEK ERICH
IPC: G06F13/42
Filed: 1990-09-26
Abstract: A method of generating wait cycles for electronic equipment, involves directly converting an address signal on a bus representing an equipment external to the controlled equipment into a number of wait cycles dependent on the address value. The conversion is performed by a logic converter (PLA). A counter (Z) started at the beginning of a data exchange with the external equipment forms a second control signal which increases with time. A controller switches the controlled equipment into a wait state at the start of data exchange. The equipment is activated when the second control signal reaches the value of the first. USE/ADVANTAGE - E.g. for wait state generation for a microprocessor communicating with a slower external device, esp. an input/output device. Time loss is prevented by adapting to the actual speed of the external device.

Filed: 1990-12-06
Abstract: A process is disclosed for producing fluid imidazolinium tensides by reaction of 1-hydroxyethyl-2-alkylimidazolines with neutralized quaternary agents and hydrolysis of the quaternary products thus obtained with aqueous bases. The 1-hydroxyethyl-2-alkylimidazolines are added at a high temperature to an aqueous solution of the neutralized quaternary agents at a molar proportion between imidazoline derivates and the quaternary agents from 1:1.5 to 1:3. The reaction mixture thus obtained is maintained at a temperature in a range of 70 to 85  DEG C for 30 to 120 minutes, 0.85 to 1.0 mol alkali metal hydroxides, referred to the amount of quaternary agents added during step (a), are added thereto within the 30 to 120 minutes at a temperature in the range of 75 to 85  DEG C, and the reaction mixture thus obtained is maintained at a temperature in the range of 75 to 90  DEG C for 140 to 220 minutes. The end products are obtained by a process that is easy to carry out if during step (a) a solution of neutralized quaternary agents is used that contains 0.025 to 0.5 mol of carboxylic acids, referred to the amount to be added of 1-hydroxyethyl-2-alkylimidazolines, and if acids are added to the reaction mixture obtained during step (d), so that when the reaction mixture is diluted with water up to a 10 wt% concentration of the product, a pH value in the range of 7 to 10 is set.
