Patent IT-1314076-B1 (IT)
Inventor: PAOLONE ROLANDO
IPC: B65B65/08

Granted: 2002-12-04
Abstract: In a machine for counting bars, for example metal bars, that are to be sent on to a packaging station which packages a pre-set number of them in bundles, the problem of precise counting of the bars is solved by using, for the conveyance of the bars to the counting station, a screw conveyor, in which each groove of the screw has a wall having a pitch increasing more rapidly as compared to the normal pitch of the screw, thus making it possible, in the case where more than one bar is present in the same groove, to render the lying plane of the bars not parallel to the specific axis of the counting means. This is obtained by providing one of the faces of the grooves either with a special step having a continuously increasing width, or with a continuously increasing inclination.

Abstract: The steel drill string attached to a drilling bit during typical rotary drilling operations used to drill oil and gas wells is used for a second purpose as the casing that is cemented in place during typical oil and gas well completions. Methods of operation are described that provide for the efficient installation a cemented steel cased well wherein the drill string and the drill bit are cemented into place during one single drilling pass down into the earth. The normal mud passages or watercourses present in the rotary drill bit are used for the second independent purpose of passing cement into the annulus between the casing and the well while cementing the drill string into place during one single pass into the earth. A one-way cement valve is installed near the drill bit of the drill string that allows the cement to set up efficiently under ambiently hydrostatic conditions while the drill string and drill bit are cemented into place during one single drilling pass into the earth.

Abstract: In a radio communication system, where a user ( 8, 9 ), who wants to transmit data, is allocated a certain transmission capacity. It is a general goal to have an efficient resource allocation algorithm. In order to serve as much subscribers of the network as possible, the allocation of the available resources is improved by determining an utilization factor, which is some kind of measure for the exploitation of the transmission capacity allocated to a user. This is done by analysing the communication activities of the user ( 8 ) by monitoring for example directly the radio link ( 10 ) between the users terminal ( 8 ) and the corresponding basestation ( 4 ) with a monitoring device ( 16.4 ). The monitoring of the communication can also be done in other locations ( 16.1, 16.2, 16.3, 16.5 ), e.g. by monitoring the communication link ( 7 ) between the basestation ( 4 ) and the mobile switching centre (MSC)( 3 ) or by directly monitoring one or more of the lower layers of the transmission protocol stack directly within one of the devices ( 8, 4, 3, 5, 9 ) being involved in the communication of the user. Then, the allocation of the resources, which is for instance carried out by the MSC ( 3 ), is done depending on this utilization factor. When knowing the utilization factor for a specific user, the resource allocation can be improved by accordingly adjusting or modifying the underlying radio resource allocation algorithm utilized by the MSC ( 3 ).

Title: Force transmitting device of a weighing valve for a vehicle[us3808954a]
IPC: F15B5/00
Filed: 1972-03-31
Abstract: A weighing valve mounted on a vehicle to produce a fluid having a pressure proportional to the load of the vehicle is activated by a force translating device which produces a proportionate force to the valve to thereby generate fluid flow changes of pressure signalling the loading on the vehicle. The force translating device has a differential piston with a plunger of smaller diameter for actuating the valve communicating with a plunger of larger diameter responsive to the load. The plunger and piston are interconnected through a deformable, incompressible medium such as silicone rubber into which both the end and sides of the smaller diameter plunger are extended thereby dampening vibrations.
