Abstract: A facility for a real-time bidding (“RTB”) bidder service to cause an RTB auction service to manage bid requests relating to a specified user is described. The facility receives a bid request from an auction service seeking a bid for presenting an advertisement to a user, including user data identifying the user; evaluates the user data; and based on the evaluating, transmits to the auction service an embargo request specifying a period of time for the auction service to prevent bid requests seeking bids for presenting advertising messages to the user from being sent from the auction service to the bidder service.

Abstract: Device and process for braking rotating and/or slewing gears of work machines comprising at least one dynamic service brake for decelerating a rotating and/or pivotal movement of the rotating and/or slewing gear, and at least one static holding brake (16), by means of which the rotating and/or slewing gear can be locked in one position, wherein at least one sensor (14) is assigned to the dynamic service brake (11a) and/or to the static holding brake (16), said sensor detecting the current movement of the rotating and/or slewing gear, and the sensor (14) being connected to a controller (13, 19) that detects an actuation of the dynamic service brake (11, 11a) said controller actuating the static holding brake (16) when in case of continued rotating and/or pivoting movement of the rotating and/or slewing gear when a dynamic service brake (11a) is still actuated.

Abstract: A drive of a sliding connecting member of a locking system of a telescopic system, having a telescopic cylinder (1) with an outer telescopic section (2, 3) and an inner telescopic section (6, 7), which are each provided with a locking hole (5) into which a locking bolt (11) can be entered and withdrawn in a releasable manner via the sliding connecting member (14), provided with a sliding path (12), and a grasper (10), wherein the locking bolt (11) is designed to be moveable by means of an engagement member (9) running in the sliding path (12) in such a way that the locking bolt (11) effects a linear movement and the jib sections (3, 6) can be connected to one another by insertion of the locking bolt (11) into the bolting hole (5) and the sliding connecting member (14) can be driven by an electric linear drive (4).

Abstract: A telescopic crane boom including a plurality of telescopically assembled tubular box sections including a base box section and an innermost box section having an open cross-section, and a boom head with a frame fixed to the outside circumference of the innermost box section. The head has a plurality of deflecting pulleys mounted on the frame, but no part extending inside the open cross section on the innermost base box section, whereby at least one additional box section can be inserted into the innermost box section in order to extend the boom.

Abstract: An auxiliary device for equipping the main boom of a mobile crane with an auxiliary boom, wherein a support is mounted near the head of the main boom, by means of which the lifting cable of the main boom may be run to a connection point on the auxiliary boom. The invention further relates to a method for equipping with an auxiliary boom.

Abstract: A telescopic crane, includes a substructure, a superstructure rotatably mounted onto the substructure, a counterweight and a telescoping boom structure which includes a main boom slewable about a luffing plane. The main boom has a boom base and at least one telescope section received in the boom base and displaceable between retracted and extended positions. At least one guy support is mounted to the boom structure and connected to a guy rope which extends substantially longitudinally in the direction of the boom structure. The guy support is oriented with respect to the luffing plane at an inclination which is so selected that a lateral load acting on the boom structure is partially or entirely received by the guying.

Abstract: A crane, includes a luffing jib having individual telescoping jib members, and a locking device configured for linkage of jib members and movable between an engagement position in which the jib members are locked together and a release position in which a first one of the jib members can be moved in and out relative to a second one of the jib members. The locking device is supported in the first jib member and received in a receptacle of the second jib member. A shifter, movable in an axial direction, is provided to shift the locking device via a coupling device between the engagement and release positions, with the coupling device extending perpendicular to the axis and connected to the shifter.

Abstract: A method of improving the properties of liquid stored or cryogenically stored erythrocytes using D,L-.alpha.-lipoic acid and/or enantiomers or derivatives thereof. Treatment with these substances results in improved oxygen release capacity (2,3-DPG), viscoelasticity and erythrocyte aggregability, and increased resistance to membrane peroxidation during storage and damage by the freeze/thaw process.

Abstract: The invention relates to the use of DL-(+/-)-.alpha. lipoic acid, D-(+)-.alpha.-lipoic acid, L-(-)-.alpha.-lipoic acid in reduced or oxidized form or of the metabolites and salts, esters, amides thereof for the preparation of medicines for the treatment of disorders caused by changes or disturbances in the rheological properties of the blood such as blood viscosity, erythrocyte flexibility and the aggregation of erythrocytes, in particular for the treatment of microangiopathy with disturbed microcirculation. It can also be used in the treatment of diabetics and of dialysis patients for protection of the erythrocytes, in central and peripheral circulatory disturbances and in tinnitus and hearing loss.
