Patent BR-8100646-A (BR)
Inventor: DE VIZZI F
IPC: H01H9/36
Filed: 1981-02-02
Abstract: Arc extinguishing arrangement in breaking devices, such as electric circuit breakers, comprising a deionizing assembly or arc chute and an arc motivating assembly flanking the contacts of the breaker. 
<??>The deionizing assembly in its preferred form comprises a high number of deionizing arc plates made of a thin magnetic sheet bent in a "U" shaped configuration with the curved portion of the "U" facing the contacts and the arms of the "U" insulated from each other by means of a thin insulating layer. The function of the deionizing assembly is one of blowing, splitting up and cooling the arc to extinction. 
<??>The arc motivating assembly in its preferred embodiment is formed by two columns of ferromagnetic material plates, wherein the magnetic circuit of said columns may be completed by a traverse yoke of a ferromagnetic material and wherein said columns and said yoke may be embedded in an insulating material forming a coating and filling the gaps between the ferromagnetic plates such as to form an arc confining chamber. The function of the arc motivating assembly is both that of pushing the arc toward the arc chute and of accelerating the opening of the breaker contacts.

Abstract: In devices for mounting electrical devices, in particular switch, command or signal devices on a plate, like a bottom plate of a switch box or an assembly plate of a switch box or switch board of the type with at least one mounting bar for the devices disposed parallel to the plate as well as with two vertically-extending supports mounted on the plate for each mounting bar and with screw connections between the supports and the mounting bar, the difficulty exists that it is hard to reach the screw connections between the supports and the mounting bars, because of tight space conditions due to a tight arrangement of the devices relative to each other and due to the wiring which leads to the devices. In order to be able to obtain a simple servicing and safe support of the mounting bars on the supports, even at the tightest space conditions, it is proposed to provide screws which are disposed vertically with respect to the plate and which cooperate with clamping plates which are so designed that by tightening the screws, the supports are rigidly connected with the mounting bar due to the clamping effect.

Inventor: MCKEE KEVIN DOUGLAS
IPC: F16D48/02

Abstract: The system includes a plurality of two-position control valves (26, 30, 36, 40), each controlling fluid flow into and out of a corresponding one of a plurality of hydraulic load devices (14, 16, 18, 20). First and second pressure responsive servo actuators (50 and 52) associated with each control valve operate to move each control valve to first and second positions, respectively. A two-position, solenoid-operated reset valve (56) controls fluid flow into and out of a pilot circuit (54). The pilot circuit communications fluid to and from the second servo actuator (52) of each control valve and to and from a plurality of two-position solenoid-operated, pilot valves (64, 66, 68, 70). Each pilot valve controls fluid flow into and out of the first servo actuator (50) of a corresponding one of the control valves. A detent mechanism (48) holds each control valve in either its first or its second position in the absence of fluid pressure in the servo actuators. A particular hydraulic function may be actuated by momentary energization of particular solenoids of the reset and/or the pilot valves. The first actuators (50) are larger than the second actuators (52) so that pulsing the reset valve and a pilot valve simultaneously sets the control valve corresponding to the selected pilot valve and resets any other control valve.

IPC: B65H59/38
Filed: 1985-08-29
Abstract: The winding equipment for winding yarn, tape or wire-shaped material comprises a bobbin shaft carrying a rotatably fixed armature plate, which is in magnetic, adjustable driving connection with a plate carrying permanent magnets and fixed on the shaft of the driving motor, the adjustment thereof resulting by a thread tension regulating device with a dancing arm carrying a dancing roller. In this connection, the motor or the shaft thereof carrying the permanent magnet plate is supported relative to the bobbin shaft carrying the armature plate radially displaceable as a function of the rotating motion of the dancing arm on the frame of the winding equipment. Owing to this radial displacement of the plates generating the driving connection, relative to each other, not only is the induced magnetic field changed in the simplest manner, but, in addition, the two plates can be arranged with the slightest air gap between each other, which, accordingly, allows for the utilization of small permanent magnets to secure a sufficient magnetic driving connection between the two plates.

Abstract: The present invention relates to a process for bleaching of lignocellulose-containing pulp, in which the pulp is treated at a pH between about 1 and about 7 in the presence of a magnesium compound, whereupon the pulp is washed and subsequently bleached with a peroxide-containing compound. The initial treatment removes from the pulp those trace metal ions that have a negative effect on the subsequent bleaching with a peroxide-containing compound. Owing to the presence of magnesium ions in dissolved form during the initial treatment, the magnesium ions are retained in those positions in the pulp where they have a particularly positive effect on the effectiveness of the bleaching stage.
