Patent DE-3010210-A1 (DE)
Inventor: SACHS BERTRAM
IPC: G10K11/34
Filed: 1980-03-17
Abstract: In an exemplary embodiment, the transducer elements are arranged in rows and columns, the transducer elements bein contacted at both sides by oppositely disposed contact surfaces, and switches being associated with the contacts of the one contact surface as well as with the contacts of the other contact surface for the purpose of adjustment of preselectable transmitting and/or receiving surface of transducer elements during a transmitting/receiving cycle, in particular, for the purpose of dynamic focusing. It is an object of the disclosure to construct an ultrasonic array which can function with an optimally low outlay of switches and which if desired also permits a transition to continuously varied apertures. In accordance with the disclosure, this object is achieved in that transducer elements, with their one contact surface in the direction of the rows, and with their other contact surface in direction of the columns, are contacted together into groups, and that there is maximally associated, with each row group, an individual common row group switch, and that there is maximally associated, with each column group, an individual common column group switch. A transfer to continuously variable aperture is possible in the simplest manner if continuously variable switching elemets, such as controllable resistances, or the like, are utilized as transmitting and/or receiving switches.

Title: Oxygen meter for IC engine exhaust gases - has parallel flow regulators to set range and compensate for aging without interrupting measurements
Inventor: ROHR FRANZ-JOSEF DR
IPC: G01N27/407
Filed: 1980-09-05
Abstract: Solid electrolyte conducts oxygen ions and has two or more electrodes. The first electrode is a measuring electrode and borders on a gas channel containing a regulator that keeps the gas flow constant and leading to the source of the gas being measured. Both electrodes can be connected ot a dc voltage so source via an ammeter. A second regulator is located in the gas channel and sets the flow to a given constant value. The second regulator is in parallel with the first. A bypass line can be connected in parallel with the gas channel and bridges that part of the channel in which the measuring electrode is located. The bypass allows part of the gas flow to be bled off before the measuring electrode. A third constant-flow regulator may also be connected in parallel with the other two. The three regulators may have the same or different cross-sections. The regulators can be switched in and out to continuously adjust the meter's measurement range and/or sensitivity without interrupting measurements. Changes in the meter's range due to ageing or contamination of the electrodes can also be compensated. The meter therefore needs little maintenance.

Patent DE-3124604-A1 (DE)
Title: Electrical switching cell
Inventor: MUELLER ROLF ING GRAD
IPC: H02B11/02
Filed: 1981-06-23
Abstract: A shaft of a driving device of a power circuit breaker carriage has a radial bearing, can rotate with an operating lever into two limit positions, has two spanner surfaces, an axial hole as well as a first and a second radial hole. A thrust element is guided in the radial hole, a locking element in the radial hole and a deflection element in the axial hole, by means of which a displacement of thrust element can be transmitted to the locking element and vice versa. The operating lever is an open-ended spanner. The radial bearing has two recesses which correspond with the limit positions of the shaft. The locking element can be recessed into the radial hole while the operating lever is being pushed on, when the shaft is located in its limit positions. At the same time, the thrust element can latch into one of the recesses. While the shaft is rotating, the thrust element is unlatched from the associated recess and the locking element is pushed out of the second radial hole, into a latching depression in the operating lever, as far as a stop, and prevents the operating lever being pulled off the shaft when it is located between its limit positions.
Patent DE-3126246-A1 (DE)
Title: Electrically operated valve
Inventor: LANG ARMIN ING GRAD
IPC: F16K31/06
Filed: 1981-07-03
Abstract: In the electrically operated valve, the hydraulic part of the valve lies outside the magnetic stray field of the electromagnet. In its capacity as an electrohydraulic transducer, it operates with a variable restriction as the output variable. In this arrangement, a restriction orifice is varied as a function of the voltage applied. Temperature-dependent influencing variables are compensated by the use of an actuating pin, the linear coefficient of thermal expansion of which is greater than that of the magnet body. For this purpose, the actuating pin may consist, for example, of aluminium. To further reduce the temperature dependence of the valve, the actuating pin contains a compensating piston which eliminates temperature-dependent hydraulic influences. Virtually complete temperature independence of the valve is achieved by further constructional measures. As an alternative to the special design of the actuating pin, the use of a bimetallic disc spring is envisaged.
Patent DE-3129741-A1 (DE)
Title: Shaft angular position encoder calibration
Inventor: HILL JERRY MILTON
IPC: G01M1/00
Filed: 1981-07-28
Abstract: The method is for calibrating a shaft encoder, which provides an indication of the angular position of a shaft, and involves the use of stored sine and cosine values as used in a wheel balancing system. Angular position data containing a reference indication and information about the increasing angular value are stored in an RAM associated with a processor. As the shaft is turned, angular position data is reproduced from the memory and the angle values monitored and compared with the stored values. It is determined whether a define number of angle values occurs between each reference value and whether the values occur in a defined sequence for a partic. direction of shaft rotation. The stored data is updated using the current information.
