Different components of television programs, such as the video and audio components or different time segments of the program, are assigned to different channels transmitted in the form of packetized digital information in at least one of the channels of a multi-channel cable television distribution system. A particular subscriber's converter (200) is configured to receive a particular subset of p...

PROCESS FOR THE PREPARATION OF METHYLPOLYSILOXANES A process for preparing methylpolysiloxanes by reacting organopolysiloxanes (A), consisting of units of the formula Ra(CH3)b(R1O)cSiO(4-a-b-c)/2 (I) in which R is a hydrogen atom, an aromatic hydrocarbon radical, a substituted aromatic hydrocarbon radical, an aliphatically unsaturated radical or a substituted aliphatically unsaturated radical, R1 ...

The invention provides blends of vinylidene chloride-vinyl chloride copolymer and vinylidene chloride-methyl acrylate copolymer which can be more readily extruded and processed at lower temperatures than those needed for the pure copolymers, multilayer films comprising such blends and their use in packaging where barrier materials are required.

Herberts Gesellschaft mit beschrankter Haftung : A process is described for producing multilayer coatings in which a first coating layer of a first aqueous coating medium is applied to an electrically conducting substrate by electrophoretic deposition, is provided wet-in-wet with a second coating layer of a second aqueous coating medium, followed by joint stoving, wherein a coating medium based on...

Closed system suction catheter assemblies have a valve controlling suction applied at the patient end of the assembly. In the present invention, the valve has a pinch tube connected in line with the catheter and secured at each end to the housing of the valve. An occluder bar midway along a pivoted lever is urged up by a spring to pinch the tube closed against a fixed occluder and close the valve....

The invention relates to signal distribution systems, such as interactive cable television systems, wherein a central server communicates with remote terminals wherein the server assigns a specific address to each newly-connected terminal for control messages and polls. In the case of an interactive cable television system, such terminal is the set-top box or converter connected between the cable ...

Trisubstituted biphenyls of the general formula in which R<1> stands for a carboxyl radical, or for a C1-C8-alkoxycarbonyl radical, R<2> stands for straight-chain or branched C1-C8-alkyl, R<3> stands for halogen, hydroxyl, cyano, C1-C6-alkoxy, straight-chain or branched C1-C8-alkyl, trifluoromethyl, trifluoromethoxy, carboxamido, carboxyl, C1-C8-alkoxycarbonyl or nitro, and R<4>...

Trisubstituted biphenyls A b s t r a c t Trisubstituted biphenyls are prepared by reacting corresponding pyridones with biphenylmethyl halogen compounds. The trisubstituted biphenyls can be employed as active compounds in medicaments.

Solutions of alkylphosphocholines in glycerol alkyl ethers can be prepared in a storage stable manner and without preservatives and oxidation protection agents by adjusting the pH value to a range between 4 pH and 6 pH. The alkylphosphocholines have the general formula: I wherein R is a C12-20 alkyl which may have a double or triple bond. The glycerol alkyl esters have the general formula: <...

Braking device, particularly usable for skates including a shoe (2) composed of a quarter (4) which is articulated to a shell (5) which is in turn associated with a frame (6) for supporting two or more wheels (7). A brake (9) is rotatably associated with the quarter (4) and selectively interacts with the ground upon a backward rotation of the quarter. The brake can oscillate in contrast with a spr...

A hub-spider assembly for a Hooke's joint in which the arms of the spider (2) include a first shaft (4), having a through-hole (41) bored in a central boss (42), the through-hole (41) axis being perpendicular to the axis of the first shaft (4), and a second shaft (5) coupled with slight interference with the first shaft (4) in its through-hole (41). At least one end of the shaft (5) is threaded or...

An agricultural tractor includes an axle body and a vehicle substructure. A generally vertical lifting structure is rigidly attached to the vehicle substructure and engages a lifting frame which is adjustable in height.
