摘要： An improved resorbable body and tissue compatible wax useful for the mechanical coagulation of blood on bones is produced by the reaction of, for example, lactic or glycolic acids with glycerol. The reaction mixture is then purified by forming a solvent suspension and washing with isopropanol to produce a purified wax essentially free of the hydroxycarboxic acid impurity, say, less than 0.1%.

摘要： The invention relates to a process for the production of (meth)acrylic acid esters of polyhydric alcohols by reaction thereof with acrylic acid and/or methacrylic acid in the presence of acidic esterification catalysts with addition of polymerization inhibitors to the reaction mixture. The new process is characterized in that, where unsubstituted phenolic compounds are used as inhibitors, the esterification reaction is carried out with addition of active carbon to the reaction mixture. The preferred inhibitor is hydroquinone. In addition, the esterification reaction is preferably carried out in the absence of liquid solvents and/or azeotropic entraining agents.

摘要： A rear brake pressure proportioning control device is disclosed, with a regulating piston (7) and with a valve closing member (9) being supported within a slidable control piston (8), the movement of the control piston interrupted at a predetermined rate of vehicle deceleration. A restriction (32) between the inlet and inlet chamber within which the control piston is disposed prevents a high rate of brake pressure increase from causing too high a rear brake pressure. A multiple-stage restrictor (26) is positioned in the inlet in order to prevent a very high rate of pressure increase of the brake pressure resulting in too low a rear brake pressure.

摘要： A new method of forming agglomerates of fine powdered solids comprises dispersing the powder in a chemically inert carrier liquid that also contains a dissolved binder precursor polymer with cyclic dicarboxylic acid anhydride groups on the polymer chain. The dispersion is shaped and then brought into contact with a second carrier liquid that contains polyamines. The polyamines react with the anhydride groups on the other polymer to form an insoluble binder polymer that hardens the shaped dispersion. The hardened shape can then be separated from the liquids and/or further reacted if desired to produce amide bonds in the final agglomerates. The method is useful for forming mechanically and thermally stable agglomerates of such materials as activated carbon, metals dispersed on catalyst carriers, etc.

摘要： A drum brake module for motor vehicles operable by electric motor and performs at least one parking brake function, having an electromechanical actuator mounted on one side of the armature plate and a rotational-translational movement converter converting a rotational drive rotational movement into a translational activation movement of brake shoes arranged on a side of the armature plate facing away from the actuator in a brake drum, and including at least one supporting device between the brake shoes such that the latter can carry out an activation movement in the direction of the brake drum. A drive nut is supported by the rotational-translational movement converter in an axially secure and rotatable fashion on the armature plate to assist the braking force. The drive nut drives a spindle arrangement mounted in a rotationally fixed and axially displaceable fashion and engages with an activation cable on at least one brake shoe.

摘要： Disclosed is a brake actuating unit for actuating a motor vehicle brake system of the ‘brake-by-wire’ type. The system includes a brake booster which is operable in response to the driver's wish both by a brake pedal and by an electronic control unit. A device is provided to decouple a force-transmitting connection between the brake pedal and the brake booster in the ‘brake-by-wire’ operating mode. A master brake cylinder connected downstream of the brake booster, a device to detect a deceleration request of the driver, and a pedal travel simulator which interacts with the brake pedal and due to which a resetting force acting on the brake pedal can be simulated in the ‘brake-by-wire’ operating mode independently of an actuation of the brake booster, and which can be enabled in the ‘brake-by-wire’ operating mode when the force-transmitting connection between the brake pedal and the brake booster is decoupled and can be disabled outside the ‘brake-by-wire’ operating mode. The pedal travel simulator (2) is enabled and disabled by electromechanical means (22, 25), electrohydraulic means (40, 47) or pneumatically operable means (96 to 98).
