Title: Injection pulse time determination - by comparing exhaust signal with reference using circuit to compensate for rich or lean mixt.
Inventor: SCHNUERLE HANS
IPC: F02D41/14
Filed: 1976-05-22
Abstract: The arrangement to determine the duration of fuel injection pulses comprises an exhaust oxygen sensor (1) whose output signal is compared with a threshold voltage (9) in a comparator circuit (7), producing an output indicating rich or lean mixture, the fuel being supplied synchronously with engine rotation as a function of engine speed and intake air flow, preferably by solenoid-operated injection valves. A circuit (12) is provided which receives the variable lower voltage limit of the sensor and acts on a threshold adjusting circuit (Ti) such that the threshold voltage, which opposes the sensor output, remains above the lower sensor voltage limit at all times.

Title: Oxidising sulphur cpds with oxygen-contg gas - in presence of mixed phthalocyanine catalyst to minimise over oxidation
Inventor: FRAME ROBERT ROY
IPC: B01J31/16
Filed: 1976-08-26
Abstract: A sulphur-contg. cpd. is oxidised with an oxygen-contg. gas in a medium having a pH of 8-14 in the presence of a mixed catalyst comprising phthalocyanines of Groups VIIB and VIII metals in a mol. ratio of 1:1 to 1:6, the oxidised sulphur compound being subsequently recovered. Preferred reaction conditions are 0-500 degrees C and 1-100 atmospheres, with a Group VIIB:VII phthalocyanine ratio of 1:3. The process is used to eliminate mercaptans and hydrogen sulphide for reasons of environmental pollution. The particular catalyst system used minimises over-oxidation with its consequent problem of colour generation in the treatment of petroleum charge stock.

Title: Sulphur di:oxide separation from combustion gases - using wash fluid from storage tank with oil cover
Inventor: HOELTER HEINZ
IPC: B01D53/50
Filed: 1976-10-16
Abstract: Removal of SO2 from combustion gases by washing with a clear wash fluid, which passes by the shortest route through a sealing layer (e.g. of paraffin oil) into a storage and recirculation container. The SO2 is expelled from the used wash fluid as required, e.g. by compressed air, and then compressed for direct use or storage. Used esp. for treatment of gases from power stations and incinerators. The SO2 is recovered as such, instead of as unwanted CaSO3 and CaSO4. Volume of wash fluid required can be much reduced by use of the oil sealing layer.

Title: Measuring technique for precision objects - includes electronic comparison of dimension with stored tolerances to derive go-no go indication
Inventor: OLZWESKI EGON
IPC: G01B7/00
Filed: 1976-11-30
Abstract: In the processing of precision objects, the control method provides control of the end point of various operational stages which have especially narrow tolerances for their nominal value. It relies on the simultaneous or serial indication of the actual measured value, with an optical indication of the result, of electronically comparing the actual value with a stored value of the tolerance limits. The precision object to be examined is brought to a measuring station and the desired parameters measured by means of mechanical probes. The measurements are transmitted electrically to a central location and compared with stored nominal values. Subsequently a GO/NO GO indication is given at the measuring station. A continuous record of the test resulsts may be made with a pen recorder.

Title: Cathodic protection appts. using sacrificial anode - where alarm signal indicates end of working life of the anode
Inventor: HOESSLE LUDWIG
IPC: C23F13/22
Filed: 1976-12-21
Abstract: The parent patent described a process and various devices generating optical and/or acoustic alarm signals indicating the end of the working life of a sacrificial anode in corrosion protection appts.; and several improvements were described in an earlier addn. The novelty in the present invention is that the sacrificial anode bar has a blind axial hole on one end in contact with a recess in the cap employed for mounting the anode; alternatively, the blind hole may be eccentric w.r.t. the axis of the anode bar, in which case the recessis counterbored so it is in contact with the blind hole. When the anode has been dissolved, liq. in a tank can travel via the blind hole to the recess to trigger and alarm signal. The present invention results in a substantial saving in the mfg. costs of the alarm devices, as compared with the earlier patents.
