Patent ES-437083-A1 (ES)
Title: Method of burning calcined and uncalcined pulverous raw material and rotary kiln plant therefor
IPC: F27B7/20
Filed: 1975-04-29
Abstract: A method is disclosed for heat treating a preheated pulverous raw material containing at least a portion of lime to produce a partial calcination prior to passing the raw material down through an inclined rotary kiln for further heat treatment. Partial calcining is accomplished by introducing into at least one end of a rotary kiln an amount of fuel sufficient for preheating, at least partially calcining, and substantially completely sintering the raw material, at least part of the fuel being introduced into the lower material outlet end portion of the kiln. An amount of oxygen containing gas sufficient for substantial combustion of the fuel introduced into the kiln is introduced into the lower end portion of the kiln, and preheated raw material is introduced into the mouth of the kiln in such a manner that the material is entrained in gases exiting from the kiln mouth. The gas and entrained material exiting from the kiln are directed into a calcination chamber communicating with the upper material inlet end portion of the kiln such that the material is at least partially calcined by the contact with the kiln exit gases. The material is thereafter separated from the kiln exit gases and reintroduced into the upper end of the kiln in a manner which permits it to pass through the kiln for further heat treatment while avoiding entrainment in the kiln exit gases. A rotary kiln plant for practicing the method is also disclosed which provides for at least partial calcining of the material initially introduced into the kiln and thereafter reintroducing the partially calcined material in such a manner as to promote passage down through the kiln for further heat treatment.
Patent ES-438899-A1 (ES)
Title: Rolling mill
IPC: B21B13/18
Filed: 1975-06-26
Abstract: A rod or bar mill stand has two work-roll carrying mountings which are pivoted together on one side of the plane containing the roll axes and which are individually connected to synchronously driven eccentrices. The eccentric drives for the roll mountings, together with the pivotal connection, cause each of the roll axes to follow an eliptical or oval path, such that each roll approaches the pass line to reduce the work, over a part only of the path. The work rolls are driven about their own axes to induce forward movement of the work.
Patent ES-438962-A1 (ES)
Title: Electro-hydraulic control system for speed-changing mechanism switchable under load
IPC: F16H61/04
Filed: 1975-06-28
Abstract: An automotive transmission with three or four stages corresponding to as many forward speeds, established by the activation of respective hydraulic coupling elements via associated electrical valve-operating switches, includes an individual delay network in the energizing circuit of each valve-operating switch for modifying its response time in dependence on load and on the direction of shift. By this modification an upshift under load or a downshift under pull proceeds with substantially immediate activation of one coupling element upon deactivation of another coupling element, whereas under other circumstances (downshift under load or upshift under pull) an appreciable hiatus occurs between deactivation and activation to take advantage of the intervening speed change. Discrimination between load and pull depends on the accelerator position whereas upshifting and downshifting are distinguished either mechanically, with the aid of a manually operated lever, or electrically on the basis of the state of activation of a coupling element of an adjoining stage. The delay networks retard either the deactivation or the activation of the associated coupling elements, depending on whether the latter are of the slow-operating or the fast-operating type.

Title: Draft and position control linkage with depth limit for a tractor
IPC: A01B63/111
Filed: 1976-12-17
Abstract: An improved draft and position control system for a tractor. Independent manually operable draft and position controls are provided for establishing a desired draft and/or position of an implement drawn by a tractor. The position control establishes the maximum lowered position to which the implement may descend and will override any draft signals which would tend to lower the implement beyond this point. The draft control includes the draft responsive member interconnected with a feedback mechanism which will tend to maintain the desired draft on the implement. An additional position feedback is provided which can moderate the draft feedback to prevent undue response of the implement during changes of the draft load. In accordance with the principles of this invention the position feedback which moderates the draft feedback can be infinitely varied between a first setting wherein it fails to moderate to a second setting where it substantially moderates. Furthermore, the moderating position feedback is inoperative over a range of movement corresponding to that movement of the implement above the ground.

Title: Communication system call transfer arrangement
IPC: H04M3/56
Filed: 1978-10-31
Abstract: A communication system call transfer arrangement is disclosed which relies on the establishment of two system access buttons (210) on every telephone (205) served by the system. The system access buttons (210) are operational to originate a call to any station in the system over any idle link. A call on either access line can be added to any other currently active line on the telephone set. The system access buttons (210) at all the stations operate such that an incoming intercom call will terminate on either button, and calls can be originated from the station by using either button (210). For call transfer purposes the system access lines are arranged such that when the station passes a call via the access line to another station and then goes on-hook, the system access lines become idle and are available for use by the station even while the transferred call is in progress.

In normal condition the thyristor (T1) is non-conducting and no current is drawn from the exchange line. The thyristor (T1) is turned on by operating a key (Re to short the gate and anode. An LED may be connected in series with the thyristor to indicate a held line.
