Title: Centrifugal pump for handling liquids carrying solid abrasive particles
Inventor: ZOLOTAR ARKADY I
IPC: F04D29/22
Filed: 1988-01-21
Granted: 1991-07-30
Abstract: Abstract A centrifugal pump is proposed for handling li-quids carrying solid abrasive particles a  casing of which has a flow-through portion formed by a dischar-ge passage and a flow-through  passage of an impeller accommodated inside the casing.  The discharge pas-sage is confined by two side walls of the casing, front and rear relative to the incoming flow of the liquid being transferred, and by a peripheral wall of the casing integral with the front and rear walls. The geometry of the peripheral wall of the casing follows the law of distribution of solid abrasive particles in the flow-through portion of the pump. The flow-through passage is formed by a carrying disk mounted on a drive shaft and having vanes secured thereto, and by a driven disk secured on the vanes. The proposed centrifugal pump, when used for trans-ferring a liquid carrying the beneficiation products of kimberlit ore having a mixture density of 1200 kb/m3, volume concentration of solids So=0.125, and size of solid particles 50 mm, has a service life of the casing of 750 hours.         A centrifugal pump embodying the features of the present invention and used in a beneficiation mill producing copper concentrate pumped an ore material of the first stage of comminution having a mixture density of 1500 kg/m3, volume concentration of so-lids So-0.2 and the size of solid particles to 1.0 mm, exhibited a casing service life of 926 hours.

Filed: 1988-05-13
Granted: 1993-07-06
Abstract: A b s t r a c t A method for installation of a floatable or buoyant body on the sea bottom.  The buoyant body is designed to be towed to the installation site in sea surface position for subsequent complete submersion down towards the sea bottom by supplying ballast to the buoyant body. The supply of ballast water is being discontinued when the buoyant body (1) reaches a pre-selected sinking velocity and the vertical movement of the buoyant body is discontinued at a pre-selected level above the sea bottom by means of a floating vessel or the like (7) which is floating at the sea surface, and one end of the vessel is connected to the buoyant body by means of a connector system the length of which is smaller than the sea depth on the installation sited.  The buoyant body is displaced laterally to a pre-selected final location, whereafter the buoyant body is further submerged down towards the sea bottom until the same is positioned on the sea bottom in a pre-selected position.

Title: Self-propelled combine-harvester
Inventor: DAMMANN JOHANNES
IPC: A01F7/06
Filed: 1988-05-20
Granted: 1992-05-26
Abstract: ABSTRACT            A self-propelled combine-harvester has a threshing unit that operates in tangential flow and is arranged at right angles to the direction of travel, and a separating device connected thereto that operates in axial flow and is arranged longitudinally to the direction of travel.  A grain-chaff return screw with associated trough is arranged on both sides of the separating device, in such a way that the lower limiting surface of the separating device lies at one and the same level as the lower limiting surface of the troughs associated with the grain-chaff screws.  Through this the separating device can be arranged as low as possible in the housing of the combine-harvester so that a favourable centre of gravity position for the combine-harvester results.  At the same time the undesired structural height is avoided.

Title: Process and packet flow control system
Inventor: LESPAGNOL ALBERT
IPC: H04L12/56
Filed: 1988-05-25
Granted: 1992-04-28
Abstract: ABSTRACT             The packet flow of each virtual circuit is measured and compared to an allocated average value. At each transmission authorization request, when found to be less than the average value, a positive difference brings about an authorization to transmit and is translated into a right to transmit which is proportional to the time span since the previous request, the right to transmit being accumulated. When it is found to be greater than the average value, a negative difference brings about, if the number of accumulated transmission rights is positive, on one hand, the authorization to transmit and, on the other hand, a decrementing of the accumulated number, and if the accumulated number is nil, a refusal of authorization to transmit.  The process and systems are applicable in particular to packets carried by asynchronous time multiplexers.

Abstract: Control Mechanism for Applying a Brake and Neutralizing a Transmission of a Vehicle A control mechanism for operating a vehicle has a housing assembly mounted for swinging movement about an upstanding axis, and a brake actuating member is mounted on the housing assembly for swinging movement about a second axis. A push-pull control rod assembly is connected to the brake actuating member and depends within the housing assembly to move a brake control element between brake-off and brake-on positions. A transmission actuating member is mounted on the housing assembly and a coupling apparatus is provided for urging the transmission actuating member to a neutral position when the brake actuating member is moved to the brake-on position. This prevents inadvertent movement of the vehicle when the brake actuating member is subsequently placed in the brake-off position.
