摘要:
Use of fluid to solid oligomeric esters of lactic acid and/or glycolic acid and dermatologically compatible derivatives thereof as resorbable carriers and/or film formers in preparations for covering undamaged and/or damaged areas of human or animal skin.
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%.

A motor and pump assembly for providing pressure to a brake actuating device of a motor vehicle brake system is described herein. The assembly comprises an electric motor and a double diaphragm pump. The pump includes a pump housing, two opposed working diaphragms, and crank drives each being coupled between the electric motor and a respective diaphragm for moving the diaphragm. A working chamber is defined between the pump housing and a working chamber cover. Each working chamber including an inlet channel, an inlet valve associated with the inlet channel, an outlet channel, and an outlet valve associated with the outlet channel, wherein the outlet channels are defined in the covers of the working chamber and in the pump housing to direct air displaced from the working chambers into an inside space of the pump housing. An air outlet unit is provided for exhausting the air from the inside space.

A partially lined disk brake includes a brake anchor plate, mountable on which are two brake linings, which are arranged at a distance from one another and which between them are capable of receiving a brake disk capable of rotating about an axis of rotation, wherein an application movement serves to bring the two brake linings into engagement with a friction surface of the brake disk, including a brake caliper, which is arranged on the brake anchor plate and which engages at least partially over the brake linings and the brake disk, and which in the direction of movement of the brake linings can be displaced by an actuating device in relation to the brake anchor plate, wherein the actuating device produces the application movement of the brake linings, and having at least one spring element, which moves the brake linings away from one another again after an application movement.

A process for antimicrobial finishing of textile fabrics, especially of wovens, includes the steps of: a) treating a textile fabric with a first dilute aqueous liquor including at least one water-soluble polymeric dispersant and/or a polymeric thickener and at least one particulate silvery constituent selected from i) sparingly water-soluble salts of silver, ii) a silver sol and iii) a pulverulent silvery material, and b) treating the textile fabric with a second aqueous liquor b) including an aqueous composition of a binder.
摘要:
The invention relates to a method of modifying the odour properties of textiles in which the textile is finished with an amylose-containing substance with an amylose content of at least 30% by weight. The invention also relates to textile materials which are obtainable by the method according to the invention.
摘要:
The present invention relates to a brake force transmission device for a brake force booster with an elastic reaction element, and input member with an associated effective surface, an output member with an associated effective surface, and a first transmission ratio that is defined by a ratio of the effective surfaces being in operative engagement with the reaction element.An object of the present invention is to provide means of a simple design, if possible arranged in the form of an assembly, giving the operator of an automotive vehicle increased support when high braking forces are required.The essence of the invention is the provision of means which starting from a determined pressure prevailing in the reaction element will reduce the reaction force introduced into the input member by a defined amount. The driver is thus given additional support, requiring a proportionately reduced increase in input force for a further increase in output force. It is thus possible for the driver to better proportion the necessarily higher brake forces after the abrupt increase in the ratio of the amplification.

A plastisol composition containing plasticizers, fillers and styrene copolymers selected from (a) styrene, .alpha.-methyl styrene and p-methyl styrene, and (b) 3 to 20% by weight, based on the weight of the styrene copolymers, of a comonomer selected from methacrylic acid, acrylic acid and itaconic acid, and optionally (c) a crosslinking comonomer, wherein the maximum of the molecular weight distribution of said copolymers is greater than 1 million as determined by gel permeation chromatography.
摘要:
The invention relates to the use of fatty acids or fatty alcohols--which are solid at room temperature and/or which cure in the presence of air--and/or at least substantially water-insoluble esters, ethers and/or salts thereof with, in particular, polyvalent cations as degradable and biologically safe stabilizers for increasing the water resistance of soil impregnations based on polyvinyl esters, more particularly PVAc.
