The claimed subject matter provides a system and/or a method that facilitates querying data across various languages. An interface component can receive data related to a portion of a listing associated with commerce in a first language. An interpreter component can translate a query in a second language to the first language to enable identification of a portion of the listing in the first language.
摘要:
A device for dispensing liquids includes one or more liquid outlet means carried on a movable head. The device forms part of an automated excision apparatus for cutting biomolecule spots from an array of such spots carried in a gel. The head is mounted on an automated motion control system to allow for movement of the head in X, Y, Z directions under the control of a control means. A displacement means for causing the dispensing of liquid from the one or more liquid outlet means of the device is also carried by the moveable head carrying the liquid delivery outlets allowing the length of the tubing between the outlet and the aspiration device, typically a syringe, to be much shorter. This means that swelling and contraction of the tube is minimized during liquid handling operations which means more accurate delivery of specified volumes through the outlet. The syringes and the outlets are mounted on opposite sides of an axis of movement of the apparatus, keeping the machine compact. Typically the axis will be a horizontal X or vertical Y axis defined by a beam or the like which supports the movable head.

Novel benzofuranylbiphenyl compounds of the formula ##STR1## which are unsubstituted or polysubstituted by radicals R=hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, phenoxy and benzyloxy and in which M is hydrogen and/or one equivalent of a non-chromophoric cation and n is the number zero, 1 or 2 and m is the number zero or 1, subject to the condition that n and m are not both zero, and the preparation and use thereof as fluorescent brighteners, for example for textiles and paper. The novel benzofuranylbiphenyl compounds are distinguished by their very good stability associated with excellent whitening properties.
摘要:
Detergents which, in addition to inorganic and/or organic peracids, contain specific bis-benzofuranyl compounds as fluorescent whitening agents. These detergents are stable for several months and already show the customary cleaning properties at washing temperatures of 20.degree.-60.degree. C.

2-Phenyl-5-benzimidazol-2'-yl-furanes of the formula ##STR1## in which R.sub.1 to R.sub.6 are as defined in the specification, n is the number 0 or 1 and A.crclbar. is a colorless anion equivalent to the cation of the fluorescent brightener, their preparation as well as their use for optically brightening organic materials are disclosed.
摘要:
Drive apparatus for a spinning can (4) effecting a rotational movement about its own axis (a) for depositing textile fibre slivers on spinning preparatory machines. The axis (a) of the can itself rotates about an axis (b) which is fixed relative to the room and which is parallel to the can axis (a). The can (4) is placed and centered on a can table (5) which is rotatably supported in a plate (7), and which is set into rotation by a rotating means (8) and is provided with a driving element (22). The plate (7) is horizontally supported on at least three points and performs a translatory circular movement activated by two cranks (14,15) moving mutually parallel. The drive element (22) of the table (5) is rotatably connected with at least one crank (14 or 15). The translatory circular movement of the plate (7) about the axis (b) is derived from the rotational movement of the can table (5) about its own axis (a).
摘要:
A turntable for the deposition of a fiber sliver into a spinning can comprising a sliver duct and calender rolls arranged, viewed in the direction of material flow, after the sliver duct and circling or orbiting therewith. Each calender roll is provided with a rotational axis which is arranged substantially parallel to the rotational axis of the turntable. The rotational axes of the calender rolls and the rotational axis of the turntable can be arranged for instance at least substantially in one plane.
