Abstract: 2.1 Fault-current protection switches for different rated currents have been in use for a long time in different designs with considerably different dimensions. Because of a requirement for a switching performance of 10 kA with a back-up fuse of 100 A, it is unavoidable to search in new ways for fault-current protection switches which cover a range of rated currents from 16 to 125 A. 2.2 The invention exhibits a fault-current protection switch which, based on a four-way basic switch for 63 A (module width 4M), covers the complete protection range from a two-way design for 40 A (module width 2M) up to the four-way design for 125 A (module width 5M). An extinguishing device (9), a contact set (10) and a drum controller (11) for each switch pole are inserted, corresponding to the width of a module (1M), in all switches in a lower part (1) of the housing, and a switch locking mechanism (12), including a trip device (14) having a module width (1M), a summing current transformer (13), a test device (15) and a contact position indicating device (16) are arranged in the upper part (3) of the housing. The high content of common components and the assembly sequence which is always the same, that is to say the virtually identical internal construction of the switches for different rated current intensities, leads to a switch family which extends from two-way fault-current protection switches which are 2 modules wide up to four-way fault-current protection switches which are 5 modules wide. 2.3 Such fault-current protection switches are provided for high powers in low-voltage networks. <IMAGE>

Title: Vtol aircraft
IPC: B64C29/00
Filed: 1991-01-11
Granted: 1993-04-22
Abstract: A VTOL aircraft including a fuselage with four nacelles, three vertical stabilizers and a horizontal stabilizer attached to the fuselage. The fuselage and the nacelles are lifting bodies that are configured to jointly form an aerodynamic lifting body which cooperates with the horizontal stabilizer to provide aerodynamic lift to the aircraft in forward flight. Each nacelle contains two rotary engines directly driving corresponding fans which face each other and operate in counter-rotating directions. Each nacelle also contains a system of vanes located at the rear opening thereof, and actuators for extending and retracting the vanes to deflect the airflow over a predetermined range of angles from the horizontal. Each engine utilizes the dynamic pressure of the air behind the fans to provide a source of air for cooling the rotors and exhaust system. A triple redundant computerized flight control system maintains the stability of the aircraft as it transitions from one flight regime to another as well as in flight. The system of vanes alone can also be used as an apparatus for gas or fluid stream directional control.

Title: Electrical switchgear
Inventor: PARRY JOHN
IPC: H01H33/18
Filed: 1982-02-02
Granted: 1985-12-19
Abstract: A first contact 10 has an end portion 16 which engages a second contact 17, 18 in a contacts closed position of the switchgear and which moves transversely across a pole face of a field coil 23 and inwardly of an axis 24 of the latter during movement of the contacts to an open position. The field coil 23 is electrically connected in series with an arcing electrode 22, and to which the second contact 17,18 is also connected. Upon movement of the contacts from their closed position to their open position, an arc is drawn between the end portion 16 of the first contact and a portion 18 of the second contact. Further movement of the contacts towards their open position causes the arc to transfer its root from the second contact portion 18 to the arcing electrode 22 so that an arcing current then flows through the field coil 23 to generate a magnetic field which causes the arc to rotate and become extinguished. Extinction of the arc is assisted by an electrically insulating fluid surrounding the switchgear. A principal arcing zone is defined by rotation of the arc, and the arc is disposed in this zone when it transfers its root from the second contact to the arcing electrode 22 so that it can rotate immediately under the influence of the magnetic field.

Title: Heat exchanger
Inventor: TOKUTAKE TOSHINORI
IPC: F28F9/00
Filed: 1991-10-29
Granted: 1993-12-02
Abstract: A heat exchanger comprises a plurality of flat tubes (1), a pair of hollow headers (5 and 6) connected to both ends of each of the flat tubes in fluid communication with them and at least one fastener (10, 11) secured to the headers. Each fasteners (10, 11) comprises at least one self-retainable embracing portion capable of being forced to fit on the header when the fastener is urged towards a side surface of the header, so that the embracing portions gripping the header are brazed thereto. The fasteners (10, 11) can be temporarily fixed, without aid of any special tools, on a heat exchanger body before they are "one-shot" brazed one to another in an oven, thus rendering easy the manufacture of heat exchanger. Due to the special tools dispensed with, a greater number of temporarily assembled heat exchangers can be accommodated in one oven, thus improving to a remarkable degree the productivity in manufacture of the heat exchanger. <IMAGE>

Patent JP-H0229908-B2 (JP)
IPC: F16J15/3244
Filed: 1985-01-23
Abstract: In the combination of a shaft with a polymeric ring having a sealing surface which flares against a counter surface on the shaft to form a dynamic sealing zone therebetween upon relative rotation of the shaft and ring, both the sealing and counter surfaces have hydrodynamically-acting feed-back elements for pumping fluid which seeps between the surfaces upon the relative rotation. The resultant, net axial component of pumping actions of the elements is in one axial direction along the shaft to pump the fluid back into the space from which it came, but the elements have different pumping actions. The different pumping actions produce a fluid circulation in the dynamic sealing zone which inhibits seal-wearing granular deposits.

Abstract: An apparatus for winding a thread or the like upon a rotatable, conical bobbin tube by means of a rotatable friction drive drum containing a plurality of rotational elements adjacently arranged upon a common drive or driving shaft and contacting the bobbin package along a generatrix. A first one of the rotational elements is rigidly rotatably connected with the drive shaft and at least two further rotational elements are freely rotatably mounted upon a respective rotational or rotary bearing mounted at the drive shaft. In one specific embodiment a respective one of these two further elements is provided at each end of the first element and such further elements are intercoupled by a differential gear arrangement. Due to the differing surface speeds of the bobbin package and the friction drive drum abrasion or scuffing occurs at the site of mutual contact of the bobbin package and the friction drive drum, such abrasion damaging the wound thread material. This abrasion is reduced to a considerable degree with the invention. Also there is afforded a reliable drive of the bobbin package, such that owing to the resultant constancy of the mean thread tension, it is sufficient to provide a non-controlled driven and therefore simpler thread storage. In the special constructural embodiment the size of the prevailing friction surface of the friction drive drum is equal to that of a non-subdivided friction drive drum, but the abrasion action is practically avoided.
