Abstract: A method is disclosed for evaluating the level of objectionable noise associated with the operation of a tire by virtue of its tread contacting a road surface, which comprises digitizing the tread de­sign on a coordinate system so as to define load-supporting portions of the tread in contact with the pavement, and distinguish them in binary form from those portions of the tread which are not in con­tact, as multiple matrix elements; defining a generally arcuate pro­file of a leading or trailing edge of a footprint of the tread by fitting an equation to the edge; sequentially performing the time ensemble summation, of the noise produced by each matrix element, over ev­ery matrix element on the entire circumferential surface; converting the sequence of summation to a periodic analog signal; converting the analog signal to a sound; and aurally evaluating the sound. In a simplified case 0's and 1's along at least one footprint edge are sequentially summed around the circumference of the tire. The system requires only a means for digitizing the tread pattern, a computer to perform the necessary manipulations of data, and a means to convert a digital signal to an analog signal. Having sub­jectively chosen a tread pattern deemed to have an acceptable noise level, ribs are then relatively rotated one with respect to another to obtain an improved level of tread noise.

IPC: F04D27/02

Abstract: In the case of known control methods for turbocompressors, in order to prevent surging before the working point of the compressor reaches the surge limit, it is ensured by controlled opening of at least one venting or reversal valve on reaching a venting line parallel to the surge limit that the flow through the compressor does not fall below a minimum through-flow which varies as a function of the delivery pressure. The disadvantage to these known methods is that surging cannot always be reliably prevented, particularly in the case of rapid shifts in the working point in the direction of the surge limit. The new method is intended to avoid this disadvantage. 
<??>The new method proposes that in addition the rate at which the working point shifts in the direction of the surge limit be determined in the performance characteristics and that if a rate-related rapid opening line running at various distances from the surge limit is exceeded, rapid opening of the venting or reversal valve be superimposed on the normal venting control. This means that opening of the venting valve occurs at the latest possible moment but always in sufficient time. The compressor can thereby still be operated safely at levels closer to its limit which results in more economic partial load operation and greater surge safety. 
<??>The new method is suitable for controlling turbocompressors for widely varying applications, for example in blast furnace blast generators, in petrochemical processes or the manufacture of fertilizers.

Abstract: This foot securing device, particularly for ski boots accommodating at least one presser (2), comprises a gap element (5) accessible from the outside of the boot. The grip element (5) actuates first means (11) adapted to adjust the pressure exertable on the presser at the metatarsal region. These first means interact with the presser (2) upon the actuation of second means (20), activatable from the outside of the boot (1) and adapted to tension at least one traction element (18 )affecting the presser at the foot instep region (4). The device thus allows the upper surface of the foot to be secured in two separate points by means of a single actuation, while allowing a separate securing adjustment at the two points.

Abstract: To provide the possibility for an external call connection in the event of a fault preventing normal switching operation (mains failure, severe software error), a preferred subscriber station (T1) is directly connected to a predetermined exchange line. If such subscriber stations are conducting external calls when a fault occurs, these are not released during the transition from normal switching operation to emergency operation or during the transition in the reverse order to this. If the exchange line (AL1) is occupied by its associated preferred subscriber station (T1) via the corresponding connector unit (AS), the time delay otherwise existing during the switch-over of the change-over unit (U) is cancelled. If this exchange line (AL1) is seized by another subscriber (Tn), the existing call connection is released by the delayed switch-over. If a call connection exists for a preferred subscriber station, a switching path is first built up to the relevant connector unit (AS) during the transition from emergency mode to normal switching operation and the speech path is prepared. It is only then that the exchange line is connected to this preparatory path by the connector unit (U). <IMAGE>

Abstract: An analyzer has a reaction disk (1) for holding a plurality of reaction containers (2) and a fluorophotometer (19) for measuring fluorescence stemming from solutions in the containers. Most of the containers contain solid phases (50) attached with antibodies (51) but at least one container does not contain any solid phase. In normal operation of the analyzer, a test sample (11) containing antigens (53) and a latently fluorescent reagent such as antibodies labeled by enzyme are added to a container (2) containing a solid phase (50). In this container, a fluorescent substance is created through an enzyme reaction. Exciting light (22) is irradiated on the container and fluorescence emitted from the fluorescent substance is measured. In mid course of measurement operation of test samples, fluorescence stemming from a reference sample (12) such as quinine sulfate is measured to produce measured values for the reference sample by which measured values for the test samples are corrected. Prior to measurement of general test samples (11) by the analyzer, fluorescence stemming from a reference sample (12) in a container removed of any solid phase is measured to enable the analyzer itself to decide whether the analyzer operates normally. In this   case, a value measured for the reference sample is compared with a setting value. When the results of comparison indicate that the normal operation is difficult to continue, the sampling operation by the pipetter is discontinued.

At least the front wheels (50) are characterized by an outer cylindrical rolling portion (54) having a plurality of teeth (80) integrally formed on an inwardly facing circumferential surface thereof. A pawl member (100) having first and second ratchet-­engaging portions (122, 124) has a cam follower portion and is mounted by a camming member (130) to the body of the skate. The camming member (130) is movable between first, second and third positions. In the first position, the camming member acts through its cam follower portion (121) to elevate the pawl mem­ber (100) to a position where it does not engage any of the teeth (80) on the inwardly facing surfaces (134a) of the front wheels. In the second position, the camming member (130, 134b) allows the pawl (100) to ride in the teeth by its own weight, establishing a ratcheting relationship permitting rotation of the wheels in only a single direction. In the third position, the camming member (130, 134c, 134d) holds the pawl (100) in the teeth formed in the front wheels (50) so that the front wheels are restrained from moving in either direction.
