Abstract: A tank ventilation system of a motor vehicle includes a vapor filter, a first line connecting the vapor filter at a corresponding first introduction point to a suction pipe, and a second line connecting the vapor filter at a corresponding second introduction point to an environment line. The second introduction point is arranged between an air filter and a compressor of the environment line. The second line includes a Venturi nozzle configured to remove carrier flow from downstream of the compressor and upstream of the throttle valve.

Abstract: A computer case containing a computer pad with electrical port, and Jumper cable removably coupled to the electrical port. A bottom compartment defined by a first and second pair of opposed bottom walls connected by a bottom wall. A top cover, including a first and second pair of opposed top walls connected by one top wall. A spacing layer, formed to substantially fill the bottom compartment. Wherein a computer pad cavity in a central region of the spacing layer has a first and second pair of opposed spacing walls connected by a spacing wall that the computer pad rests upon. A jumper cable cavity extending from an edge of the computer pad, positioned next to the electrical port, terminating at a case electrical port. Wherein the jumper cable within the cavity may be coupled to the computer pad and one of the first and second pair of opposed bottom walls.

Abstract: A vessel electrode line (10) for pacemaker stimulation and/or for sensing cardiac actions in the region of the atrium has an oblong base body (11) that receives at least one electrode supply line, and at least one electrode (13, 14) that is mounted on the base body, with the effective diameter of the electrode(s) being nearly identical to the diameter of the base body, and with fixing elements (11a) that essentially do not act as an electrode, and particularly have at least a partial insulating surface, being provided for fixedly positioning the electrode(s) with respect to the vessel wall.

Abstract: An arrangement is provided for providing a vacuum for the brake power assist unit of a motor vehicle having a vacuum pump which can be connected as required as a function of the operating conditions, and at least one other additional pump being provided for the buildup of a sufficient vacuum in the brake power assist unit. The additional pump is a secondary air pump already present in the vehicle, the controlling of the vacuum pump taking place simultaneously with the switching-on of the secondary air pump.

Abstract: The invention relates to a process for controlling the degree of attrition or wear of a sealing screw (8) conveying a plasticized material, in particular synthetic plastic material, against an resistance, wherein the sealing screw (8) is bearingly supported within a screw housing (4). For this, the pressure of the conveyed material is measured at two locations spaced apart from each other, when seen in direction of conveyance. These two locations are disposed on both sides of a resistance body (12) towards which the sealing screw (8) conveys. The difference of the two measured values is used for indicating the degree of wear of the screw (5) or its housing, respectively.

Abstract: A device for manufacturing uniform sheets from paper panels having a cutter roller which has, at its circumference, at least one pair of blades which interact with a stationary counter blade. Each blade is individually adjustable and is fastened to a mounting surface of a prismatic recess wherein the mounting surface extends parallel to the rotation axis of the cutter roller. Each blade is adjustable by way of a feeding member which acts perpendicularly on the blade for radial adjustment of the blade.

Abstract: Toxic refractory organic substances are decomposed by exposing them to an oxidizing medium and steam at a temperature in the range of 2500.degree. F. to 3200.degree. F. for a period of 5 to 500 milliseconds in a reaction chamber. The toxic refractory organic substance can be dioxins, polyhalogenated byphenyls, organophosphates, halogenated biocides, waste streams from the production of said toxic substances, and mixtures thereof.

Abstract: A filter apparatus, particularly for filtering extruded thermoplastic synthetic plastics material, has a housing, within which two carrier members are shiftably arranged, each of which carries a sieve means consisting of two filter sieves. The material to be filtered is supplied to the entry side of the sieve means via an inlet passage. Within each carrier member there is provided a rinsing passage being in connection with the outlet side of the sieve means. The rinsing passage can be connected with the outlet passage when shifting the carrier member into a rinsing position. In this rinsing position, the entry side of the sieve means is at least partially connected with a space receiving the sieve contaminations or opens into atmopshere, respectively.

Abstract: A tool which is used to make rows of perforations in a running web of paper or the like has a rotary holder and a flat blade which is removably secured to the holder so that one of its longitudinal edge faces extends beyond the periphery of the holder. Such one longitudinal edge face has a row of perforating teeth and the blade has an elastically deformable portion which extends lengthwise of the one longitudinal edge portion to enable at least some of the perforating teeth to yield if they engage a hard surface while the row of teeth bulges outwardly in the region between the ends of the one longitudinal edge face. The elastically deformable portion can have one or more rows of slots or one or more corrugations. If the elastically deformable portion has two rows of slots, the slots in the row which is nearer to the perforating teeth partially overlap the neighboring slots of the adjacent row.

Abstract: In a hydrostatic gear machine of the type having an internally toothed outer gear and an externally toothed inner gear wherein the gears have different numbers of teeth, the gears being meshed with the outer gear surrounding gear, particularly advantageous relationships between the numbers of teeth and the shapes of the tooth flanks are provided to permit economic manufacture of the machine for use as a motor or pump.

Abstract: An enhanced petroleum oil recovery method for increasing the quantity of oil recoverable from an underground deposit thereof is provided which involves injecting into a first point in such deposit a liquid mixture of low molecular weight, light hydrocarbons; alternately reducing and raising the back pressure exerted on said deposit so as to alternately induce boiling and condensation of said light hydrocarbon mixture; recovering from a second point in said deposit under controlled back pressure a mixture of said light hydrocarbons and oil; separating the light hydrocarbons from the extracted petroleum oil by distillation; and then recycling the light hydrocarbons to the injection step. Another aspect of the invention involves utilizing the essential features thereof for the recovery of oil from oil-bearing sands, e.g. tar sands, which are mined and brought to the surface.

Abstract: A slagging gasifier for the gasification of coal and organic waste materials is disclosed The gasifier includes a vertical blast furnace having a hearth section at the bottom thereof. A slag tap hole is formed in hearth section and opens into a quenching vessel. A honeycomb structure is formed on the inner surface of said hearth section in the area surrounding said slag tap hole, and the inner wall of the hearth section. A plurality of tuyeres extend into the hearth section and feed the furnace with steam and oxygen so as to permit the oxidation of coal and organic waste materials fed into the furnace. As a result of the oxidation, gas and molten slag are formed in the furnace. The slag is collected in the hearth section and exits the hearth section via the tap hole.

Abstract: A rotatable shaft has a roller electrode mounted on it for rotation therewith. A transformer and a rectifier are structurally integrated to form a unit which is also mounted on the shaft for rotation with it, and serve to convert high-voltage low-amperage net current into low-voltage high-amperage DC current. Slip rings are mounted on the shaft to transmit electrical current to the unit for supply to the roller electrode.
