Title: Random comb polymers, process for preparing them and their use
Inventor: HARTL ANGELIKA
IPC: C04B24/00
Filed: 2004-08-17
Abstract: The invention relates to statistic comb polymers that are obtainable by the radical copolymerization of a vinylic poly(alkylenoxide) compound (A) with an ethylenically unsaturated monomer compound (B) according to the catalytic chain transfer method (CCT). The inventive comb polymers are extremely suitable for hydraulic binder suspensions based on cement, lime, gypsum and anhydrite as they have, for the same dosage, an improved water reducing power over conventional flow agents based on prior art comb polymers. The corresponding building material mixtures are characterized by a substantially reduced stickiness and plastic viscosity once said comb polymers are added, which dramatically improves the plasticity of very cement-rich building material mixtures, such as concretes. The building material mixtures using the inventive flow agents have a considerably increased slump flow at identical slump as compared to those comprising conventional poylcarboxylate ether flow agents. The building material mixtures and especially concretes, at identical water/cement ratio, have an increased shear-thinning behavior as compared to conventional concretes while not having the tendency to segregate ("bleed").

Title: Method and device for assessment of a series of glucose concentration values of a body fluid of a diabetic for adjustment of insulin dosing
Inventor: KLOETZER HANS-MARTIN
IPC: A61B5/00
Filed: 2006-05-24
Abstract: The invention relates to a method for the assessment of a series of glucose concentration values of a diabetic for adjustment of the dosing of insulin administrations, whereby glucose concentration values g(t1) to g(tn) that are related to time points t1 to tn that are distributed over a period of time of at least four hours, preferably at least six hours, are used as input parameters, comprising the following steps:   - based on the concentration values a disturbance parameter is determined that characterizes the type and/or severity of a disturbance of the tested glucose metabolism that is manifest despite the administration of insulin;   - the disturbance parameter is assigned by means of predetermined parameter ranges to one of at least two predetermined classes, whereby recommendations for adjustment of the dosing of the insulin administrations are assigned to each of the classes as output parameters According to the invention, in order to determine the disturbance parameter, first the concentration values g(t1) to g(tn) are used to calculate disturbance values w(g(t1)) to w(g(tn)) as function values of a weighting function w, and then, in a further step, a statistical analysis is used to determine the disturbance parameter from the disturbance values. Moreover, a device for carrying out this method is described.

Title: Improved wellhead drive braking mechanism
Inventor: GRENKE EDWARD
IPC: F04B47/02
Filed: 2006-06-09
Abstract: The present invention provides in one aspect a braking mechanism for slowing the release of torsional potential energy in a rod string of a wellhead drive system on the shutdown or power failure thereof. The braking mechanism, without using a slip clutch, slows the backspin of the rod string by using the rotational energy of the rod string to turn a fluid pump to pump fluid through a constriction orifice in a closed fluid circuit. The present invention reduces the space required for t he braking mechanism and moreover reduces the number of moving parts within the braking mechanism which may reduce the likelihood that the braking mechanism will require maintenance or fail, as well as reduce the manufacturing cost. In another aspect, the present invention provides a wellhead drive system for driving a rotary downhole pump which includes the inventive braking mechanism described above.
