Abstract: An assembly (19) for damping torsionals in a vehicle driveline. Assembly (19) includes a spring assembly (20) and a vane damper assembly (22) disposed in parallel and immersed in automatic transmission fluid of a torque converter housing (24). The spring assembly (20) isolates driveline torsionals and the damper assembly (22) dissipates the torsionals. The damper assembly (22) includes first and second relatively rotatable housing members (66,68) respectively connected to the spring assembly output (62b) and input (62a). Members (66,68) are also frictionally interconnected by surfaces (68a ,74a). Rousing members (66,68) define chambers (78a,78b) which vary inversely in volume in response to flexing of the spring assembly (20) by the driveline torsionals. The chambers are in communication with the fluid in the torque converter housing via restricted passages (86,88). As the chambers vary in volume, energy from the torsionals is converted to fluid pressure in the chambers decreasing in volume. The pressure increases the engagement force of the friction surfaces. Lugs (77a) drivingly connecting the second member (68) to the torque housing include valving members (77c,77d) which close or partially close the passages associated with the chamber decreasing in volume.

Abstract: In pilot-controlled pressure control valve arrangements, reactions caused by pressure oscillations and affecting the switching behaviour of inlet and outlet valves are to be prevented. The pressure control valve arrangement (1) has an inlet valve (15) and an outlet valve (16), the valve closing member (23,33) of which is held in the closed position by pressure in an adjoining control chamber (22,32). Pilot control valves (17 and 18) assigned to the inlet valve (15) and the outlet valve (16) are capable of releasing outlet passages (24,35), via which the control chambers (22,32) can be vented into a pressure-medium outlet chamber (7) on the load side or a pressure-relieved pressure-medium outlet chamber (9). Reactions from these chambers (7,9) into the respective control chamber (22,32) are prevented by a non-return valve (25,36) arranged in the corresponding outlet passage (24,35). The pressure control valve arrangement (1) is, for example, intended for use in pressurised air vehicle braking systems. <IMAGE>

Abstract: An apparatus for directly reducing pellets of material without melting the material includes the transporting of the pellets through drying and preheating zones on an oxidizing traveling grate and reduction in a ported rotary kiln. There is a kiln having a first end and a second end with the first end being substantially adjacent to the heating and oxidizing component for receipt of the pellets therefrom. The kiln is inclined downwardly and is rotated to advance the pellets through the kiln from the first end to the second end thereof. The kiln includes an induration zone for indur­ating the pellets. The induration zone is adjacent to the first end and remote from the second end and extends for a substantial portion of the kiln from the first end. The kiln includes a reduc­tion zone extending from the downstream end of the induration zone to the second end. A device is used to inject a reducing agent into the reduction zone of its kiln for making contact with the pellets advancing through the reduction zone. The kiln is heated to assist in a reduction of the pellets in the reduction zone. The pellets advancing through the induration zone are substantially free of contact with the reducing agent. The invention also in­cludes the process for directly reducing the pellets of material.

IPC: H03L7/107

Abstract: The present invention relates to frequency synthesis with a controlled oscillator (20) included in a phase locked loop, where the frequency of the oscillator output signal is divided (22) periodically by different integers, such that the frequency is, on average, divided by a value which is equal to an integer N plus or minus a numeric fraction whose absolute value is smaller than one. The phase position of pulses formed in this way is compared with the phase position of pulses which derive from a reference signal (10, 12), therewith forming a phase error signal. For the purpose of suppressing periodic variations of an oscillator control signal as a result of phase jitter, there is added or subtracted to the phase error signal, in a known manner, a correction value (24, 26) which is dependent on the aforementioned numeric fraction. In order to eliminate the need to multiply the correction value by a factor which is proportional to the inverted value of the integer N, the phase error signal is instead amplified with a factor N (28) prior to adding or subtracting the correction value. The loop bandwidth is also held constant in this way.

Filed: 1990-02-21
Abstract: A process is described for the separation and recovery of isocyanate monomers from isocyanate concentrates which leaves a residue which is liquid and burnable. The process for the separation and recovery of isocyanate monomers from isocyanate concentrates formed in the production of isocyanates and comprising a volatile isocyanate monomer and by-products comprises the steps of: (A) preparing a mixture comprising (A-1) the isocyanate concentrate; and (A-2) an oil solution comprising; (A-2-a) a major amount of hydrocarbon oil, and (A-2-b) a minor amount of at least one ashless dispersant; and (B) heating the mixture to an elevated temperature at reduced pressure whereby isocyanate monomer is distilled and recovered leaving a liquid residue. The presence of the oil solution in the mixture facilitates the distillation of the isocyanate concentrate, generally improves the yield of distilled isocyanate monomer, results in a residue which is liquid and easily removed from the distillation apparatus, and the liquid residue can generally be burned without difficulty.

Abstract: A numerical controller having a main processor (1) for NC control and a plurality of subprocessors (61a, 61b) for servo control provided to meet the number of the controlled shafts. Between the main processor (1) and the subprocessors (61a, 61b), there are provided LSIs which contain shared RAMs (91a, 91b) for data exchange and arbitration circuits (94a, 94b), respectively. These LSIs (9a, 9b) are provided for their respective subprocessors (61a, 61b), and they act between the main processor (1) and the corresponding subprocessor (61a) only. Further, since the circuit that includes the LSI (9a, 9b) and the corresponding subprocessor (61a, 61b) for servo control is constituted as an independent module, the numerical controller can be easily realized to control an increased number of shafts by simply increasing the modules depending upon the number of shafts to be controlled.

Abstract: L'invention se rapporte à une installation de sécurité anti-collision avec coussin pneumatique gonflable (1), qui reçoit un gaz propulsé à partir d'un organe de gonflage (2), lequel est actionné en cas d'urgence et gonfle un coussin pneumatique (3), en vue de protéger un passager. Une partie du coussin pneumatique (3) proche de la partie de raccordement de l'organe de gonflage, au niveau de laquelle un tissu de renforcement (7) est cousu et qui est directement exposée au jet du gaz sous haute pression propulsé depuis l'organe de gonflage (2), est recouverte d'un tissu ignifuge (10). Ainsi, le gaz sous haute température propulsé depuis l'orifice de propulsion de gaz de l'organe de gonflage (2) vient directement heurter le tissu ignifuge (10) qui fait office d'écran et empêche le gaz sous haute température, immédiatement après sa propulsion, de venir heurter la partie de fixation du tissu de renforcement (7) du coussin pneumatique (3). Les fils de couture (8, 8') ou un adhésif utilisés pour fixer le tissu de reforcement (7) ne risque par conséquent pas de fondre. Etant donné que le tissu de renforcement (7) se trouve fixé au coussin pneumatique (3) sans risque de séparation lors du processus de gonflage et de dépliage du coussin pneumatique (3), ce dernier peut être renforcé en toute fiabilité.
