Title: Continuous fuel injection device
Inventor: HOFBAUER PETER PROF
IPC: F02M69/08
Filed: 1985-07-03
Abstract: The device for the continuous injection of fuel into the intake line of a mixture-compressing internal combustion engine has an air pump (9) drawing in a secondary air flow derived from the intake line (2) and a fuel pump (4), which feeds the fuel from a fuel tank (3) to a metering device (7) adding the fuel to the secondary air flow as a function of the operating state of the internal combustion engine (1). In order to reduce the manufacturing cost for the fuel pump (4) and the metering device (7), it is proposed that the passage cross section of the line (21) carrying the secondary air flow be so designed in the area of the mixture forming device (8) that an injector effect reducing the pressure level of the fuel pump necessary for injection is produced in the area of the outlet openings of the metering device adding the fuel. <IMAGE>

Title: Steering device
Inventor: SISTIG KURT
IPC: B62K9/00
Filed: 1985-07-03
Abstract: The invention relates to a steering device for steering-wheel-less vehicles which are moved by human physical effort and devices such as children's prams, toy cars, roller skates or skateboards whose chassis or bearing plate rests on at least two axles equipped with wheels or rollers. The frontmost axle is mounted so as to be axially displaceable in a limited fashion preferably in an axle tube attached to the chassis. The wheels of this axle are connected to a track rod via rotatably mounted axle stubs and track-rod levers which engage on the latter, which track rod is non-displaceably attached to the part of the chassis lying in front of this axle. Thanks to this construction, when lateral pressure is applied the chassis can be displaced along the wheel axle with respect to the wheel stub bearings which are arranged at a fixed distance from one another and have a frictional contact with the carriageway via the wheels. By means of the track rod which is also moved in this process, the two front wheels are swivelled into the position for the intended travel around a bend which corresponds to the displacement direction so that the respective bend can be travelled through smoothly in accordance with its degree of curvature.

Title: Process for coating micro-indentations
Inventor: LARDON MARCEL DR
IPC: H01L21/768
Filed: 1985-11-27
Abstract: When coating substrate surfaces which have so-called micro-indentations (grooves, holes) having a lateral extent of less than 5  mu m, especially those whose depth is greater than their width, there is a risk of cavities being formed in the indentations below a vapour-deposited layer. In order to avoid this, the coating is carried out, according to the invention, using coating material molecular beams, whose divergence must not exceed 10 DEG , and the coating material in the indentations is in part dusted off again by ion bombardment and thus is distributed more effectively on the side walls thereof. Application of the invention primarily in microelectronics.

Patent DE-3602778-A1 (DE)
Title: Vessel-occluding device
Inventor: KIRCHNER HANSJOERG
IPC: A61B17/132
Filed: 1986-01-30
Abstract: The vessel-occluding device essentially comprises the basic body (1), the holding piece (2), a belt (3) and a two-armed lever (4). The lever is held with limited pivotability on the holding piece at a distance from a transverse web (18) and its inner end or the free end of the second lever arm (16) of this two-armed lever forms, together with the transverse web (18), a passage (28) for the end of the loop (12) on the side of the basic body. When the loop (12) is taut the tensile force in the loop exerts a moment (14) on the two-armed lever (4), so that the belt is clamped between the first lever arm (13) and a counter-surface (11) of the basic body (1). The belt is released by the release key (31) formed by the outwardly guided end of the first lever arm (13) of the two-armed lever (4) being depressed in the direction of the arrow (38), or else by the holding piece (2) being pivoted in the direction of the arrow (39) towards the basic body (1), and this leads to spreading or enlargement of the gap (19) between the two free plate ends, so that the holding piece (2) springs automatically off the transverse web (18) due to the tension in the loop (12) in the direction of the arrow (14). <IMAGE>

Patent DE-3620137-A1 (DE)
Inventor: WILHELM RAIMUND
IPC: B23P19/06
Filed: 1986-06-14
Abstract: A power-wrench bolting spindle (1) is used to insert and tighten screws or nuts. The bolting spindle is driven at one end by a motor through a reduction gear (5) and at its other end a bolting tool is seated. A torque sensor (7) is mounted between the motor and the spindle. During bolting, other essential data besides the bolting torque are ascertained. The bolting spindle is equipped with a depth sensor (24) connected to the regulating circuit to measure the depth of bolting. An angular-speed sensor is connected to the regulating circuit and measures the motor or spindle angular speed. The bolting procedure is carried out in two operational stages separated by a pause, namely an application stage (L) and a tightening stage (Z). Each of these operational stages terminates when a specific shutdown bolting torque is reached. Due to the control by the depth sensor, the bolting angular speed is lowered from its initial value when approaching the application stage to a final value which, when the shutdown bolting torque is reached, allows stopping without overloading.

Title: Method and circuit arrangement for acoustically compensating for the environmental noise in headphone reception
Inventor: SCHWARZ DIETER DIPL ING
IPC: H03G3/32
Filed: 1986-08-08
Abstract: In a very noisy environment, considerable losses of intelligibility can occur even in headphone reception. To compensate for the acoustic feedback in a hands-free talking station, an additional signal is fed into the listening path. The component of the additional signal acoustically fed back to the microphone from the loudspeaker is compared with the additional signal fed in, the magnitude of the feedback factor is determined and the volume of the loudspeaker is set as a function of this. To be able to carry out a simple adaptation to the respective interfering noise in a very noisy environment, the environmental noise picked up by a reference microphone is used as the additional signal according to the invention. The environmental noise picked up by the reference microphone is supplied to a compensation filter and the filter output signal is superimposed in negated form on the useful signal in a loudspeaker located at the end of the listening path.
