Title: Arrangement for regulating the air/fuel ratio of an internal combustion engine
Inventor: OHARA YOSHIAKI
IPC: F02M7/24
Filed: 1981-02-27
Abstract: An arrangement for regulating the air/fuel ratio of an internal combustion engine has a twin carburettor, an intake duct, two throttle valves, an exhaust duct, an oxygen sensor for determining the concentration of the oxygen in the exhaust gases, an on-off solenoid valve for correcting the air/fuel ratio of the air/fuel mixture fed in by the carburettor, and an electronic control device. The electronic control device contains an assessment circuit for comparing the output signal of the oxygen sensor with a stoichiometric reference value, an integrating circuit connected to the assessment circuit, a square-wave pulse generator and a drive circuit for the production of drive pulses to drive the on-off solenoid valve device for regulating the air/fuel ratio to a value approximately equal to the stoichiometric air/fuel ratio. A constant-signal generating circuit is actively connected to the electronic control device as desired. An engine operation detector is provided for the determination of the change from a heavy-load state to a light-load state and generates a signal. A circuit actively connects the constant-signal generating circuit to the electronic control device in order to produce a fixed duty ratio of the valve and makes the electronic control device unresponsive to the output signal of the exhaust detector. A switch actuation circuit is provided in order to actuate the switch by the output signal of the engine operation detector for a predetermined time. The on-off solenoid valve is thus operated with a lower duty ratio for a predetermined period following the heavy-load state. <IMAGE>

Title: Continuous press for pressing chipboards, fibreboards and similar compressed material
IPC: B30B5/06
Filed: 1981-10-29
Abstract: The invention relates to a continuous press for pressing chipboards, fibreboards and similar compressed material. In its basic construction, the press comprises an upper press part and a lower press part, pressing bands being led over deflecting drums at the beginning and end of the upper press part and the lower press part. At least in the upper press part there is arranged a pressing pressure generating roll between the deflecting drums. The upper press part is divided into two upper part sections. One bears the pressing pressure generating roll. This upper part section is able to pivot on the second upper part section, with a fixed setting at least when the press is operating, about an articulation arrangement with horizontal axis. This achieves the effect that the overall mass of this upper part section acts in a way generating pressing pressure on the material to be pressed. Therefore, the upper part section which bears the pressing pressure generating roll is preferably very much longer than the other upper part section. It bears the pressing pressure generating roll in the region of the articulation arrangements. <IMAGE>

Title: Standby power supply circuit for a load supplied by a dynamo
Inventor: BRIEM ALFRED ING GRAD
IPC: B62J6/00
Filed: 1981-11-19
Abstract: An electrical circuit is described for briefly supplying power to a load which is supplied by a dynamo, in the event of dynamo failure. The load is connected on the one hand in the dynamo circuit and on the other hand in a standby power circuit which, however, is switched off by a semiconductor switching element during normal dynamo operation. The semiconductor switching element is controlled by the combination of a large and a small capacitor which are interconnected with their polarities in reverse-parallel via a resistor with a high resistance, the small capacitor normally being connected with its negative terminal to the control electrode of the semiconductor switching element, and switching it off. If the dynamo fails, the large capacitor discharges via the control electrode of the semiconductor switching element, so that the latter switches on for the duration of the capacitor discharge and connects the load to the standby power source. Once the capacitor has discharged, the voltage on the control electrode of the semiconductor switching element drops below the threshold value of the switching element again and the current from the standby power source to the load is automatically interrupted. The circuit contains a direct connection from the dynamo to the standby power source via a diode, so that charging of the power source takes place if an accumulator is used as such a power source. When the standby power circuit is used in a bicycle, it is proposed that it be housed in the seat pin of the bicycle.

Inventor: SPIES ALFONS DIPL ING
IPC: G01D3/02
Filed: 1982-01-15
Abstract: An error correction system for correcting machine errors or division errors in a position measuring instrument for precision machines is disclosed. The system is usable, for example, in conjunction with instruments for measuring the relative position of two objects, wherein an incremental grid division formed on a measuring scale is scanned by a scanning unit to generate analog measurement signals. According to this invention, the scale defines additional correction tracks which extend along the scale, parallel to the division, and are scanned by additional scanning elements included in the scanning unit. These additional scanning elements operate to generate analog correction signals from the correction track. These analog correction signals are used to correct the analog measurement signals with respect to errors such as amplitude errors, phase angle errors, and zero crossing errors.
