摘要:
Suggested is a mixture of matter, comprising: (a) steviol glycosides, (b) starch degradation products and (c) one or more phenolic sweetness-enhancing aroma substances selected from the group formed by hesperetin, phloretin, 1-(2,4-dihydroxyphenyl)-3-(3-hydroxy-4-methoxyphenyl)propan-1-one, 7,3-dihydroxy-4′-methoxyflavan and 5-hydroxy-4-(4-hydroxy-3-methoxyphenyl)-7-methoxy-2-chromanone. On condition that components (a+b) and (c) are present in a ratio by weight of from 1.99 to 99:1.
摘要:
The invention concerns an aroma composition to reduce or suppress a bitter or astringent impression in the oral cavity, comprising (i) one or more sweeteners and (ii) one or more specific bitter-masking aroma substances and/or flavourings and optionally (iii) one or more sweetness intensifying aroma substances and/or sweeteners and optionally (iv) one or more inactive substances or carriers. The invention also concerns a preparation, containing such an aroma composition, the use of an aroma composition for reducing or eliminating a bitter and astringent effect of an artificial sweetener and a corresponding method for reducing or eliminating the bitter and astringent effect of a sweetener.

The invention relates to the use of rubusoside and certain mixtures containing rubusoside, preferably the use of certain rubusoside-containing mixtures, in particular Rubus suavissimus extracts, for masking, reducing or suppressing a bitter, sour and/or astringent taste impression. The invention further relates to orally consumable preparations, comprising at least one bitter, sour and/or astringent-tasting substance and rubusoside or certain rubusoside-containing mixtures, preferably certain Rubus suavissimus extracts, a corresponding method of producing said preparations and a method for reducing or suppressing the bitter, sour and/or astringent effect of a bitter, sour and/or astringent-tasting substance. The invention further relates to certain flavoring compositions that are particularly effective for masking, reducing or suppressing a bitter, sour and/or astringent taste impression.

The use is described of the 4-hydroxychalcone derivatives of the formula (I) wherein A may represent a single or double bond, R1, R2 and R3, mutually independently, may in each case mean H, OH or (preferably C1-C4) alkoxy, providing that at least one of the residues R1 to R3 means OH, and R4 means H, OH or (preferably C1-C4) alkoxy, and/or (ii) the salts thereof and (iii) mixtures thereof to mask or reduce the unpleasant taste impression of an unpleasant tasting substance, as are corresponding methods and preparations.
摘要:
A release mechanism for actuating a friction clutch between an internal combustion engine and a transmission of a motor vehicle that is designed for concentric assembly on a guide sleeve mounted on a transmission shaft in order to bear against a release spring of the friction clutch where the guide sleeve and the friction clutch each having a respective center axis. The release mechanism includes a clutch release bearing. The release mechanism also includes a first device for compensating for at least one of a tilt between the center axes and wobbling eccentricity of the release spring where the first device includes a spherical surface between the release bearing and the guide sleeve, and a second device for compensating for offset between the center axes.

A lip seal for sealing cylindrical surfaces of a cylindrical housing and a axially movable piston within the housing includes an annularly arranged supporting bead on its outer diameter to improve its tilting behavior around a central axis running annularly through the center of the lip seal. A first sealing lip of the lip seal forms a seal on the cylindrical surface of the housing and a second sealing lip forms a seal on the cylindrical surface of the piston. The supporting bead, in the installed state, forms a contact seal in the cylindrical part of the housing. Together with the contact seals of the first sealing lip and the second sealing lip, the supporting bead lends stability against tilting to the lip seal. Advantageously, a good sealing quality of the lip seal is maintained during an increased number of load changes.
摘要:
A detachable plug-type connector, in particular for the connection of a pressure line to a hydraulic cylinder with a pin-shaped inner part, which pin-shaped inner part can be inserted in a boring of an outer part. Between the outer part and the inner part there is a seal. The seal sits in the boring of the outer part, and in front of the seal there is a securing element which limits the axial travel of the seal in the extraction direction.

Presented is a hydraulic coupling for an actuating system for actuating a motor vehicle clutch. The hydraulic coupling includes a socket part defining an internal recess, a plug part configured for insertion into the socket part, a locking element that engages with the plug part and the socket part in an assembled state of the hydraulic coupling and which holds the plug part and the socket part captively together, a damping element that is configured for damping undesirable vibrations, with the damping element being supported on the locking element, and a support element disposed between the damping element and the locking element and extending around the entire circumference of the damping element.

A release device for a friction clutch includes a guide tube, a sliding sleeve mounted on the guide tube, and a release bearing mounted coaxially to the sliding sleeve, the bearing including a first bearing race, rolling elements, and a rotating second bearing race. The second bearing race supports a connecting element, which establishes the working connection between the release bearing and the ends of spring tongues of a diaphragm spring, which serves as the actuating element of the friction clutch. The connecting element has a receiving section, which holds the ends of the diaphragm spring tongues and can shift position in the radial direction in opposition to a restoring force, and a retaining section for the second bearing race. Radial is placement of the ends of the diaphragm spring tongues which occurs upon axial actuation of the releasing device can be absorbed by the connecting element with essentially no friction.
摘要:
A cylinder for pressure media, in particular a hydraulic master or slave cylinder in motor vehicles, having a bleed element which can be screwed into an aperture in the cylinder casing and which bleed element is sealed against the casing. The bleed element is functionally connected in the vicinity of that end inserted in the casing to a round sealing element, which is pressed axially against a shoulder in the aperture.
