Abstract: Tampon, especially for feminine hygiene, formed from an approximately cylindrical blank which is shaped by winding up a portion of length of tape-shaped nonwoven material, and the circumferential surface of which is pressed radially relative to the longitudinal mid-axis of the blank over an even number of at least six portions mutually adjacent in the circumferential direction of the winding blank, characterized in that only narrow strip-shaped portions of the circumferential surface of the winding blank, which are arranged at equal angular distances from one another, are pressed to produce a preform which, as seen in cross-section, consists of a central approximately circular fibre core of high compression and buckling strength and of longitudinal ribs of softer fibre structure and with a coarser capillary structure which extend radially outwards from the fibre core and which are separated from one another by outwardly open longitudinal grooves, and in that, accordingly, only the soft longitudinal ribs of the preform have been exposed to a low uniform pressure, radial relative to the longitudinal mid-axis of the preform, in such a way that the outer ends of the longitudinal ribs form a soft essentially smoothly cylindrical surface of smaller diameter, with the coarser capillary structure corresponding to the final form of the tampon being maintained, and process of making same.

Title: Procedure and apparatus for the control of a hoisting motor
Inventor: HAKALA HARRI
IPC: H02P29/00
Filed: 1990-10-29
Granted: 1995-12-05
Abstract: A method and an apparatus for the control of an elevator a.c. or d.c. hoisting motor driven by a frequency converter unit, or by a rectifier unit, supplied by a three phase power source is disclosed. The voltage of the mains power source is monitored using a voltage measuring unit. The frequency converter or rectifier is supervised by a control unit which selects a speed reference curve, best suited for a run. The controller unit allows the elevator speed to be varied continuously with the mains voltage so that the elevator always travels at the highest possible speed.  When an undervoltage condition is detected in the mains power source, the rotational speed  of the hoisting motor is reduced without modifying the acceleration so as to  avoid  an overcurrent  in the rectifier or  inverter switches. If, in addition, the acceleration is decreased before the maximum speed is obtained,  a higher maximum speed may be obtained for a given low level of supply voltage. The solution offered by this invention  enables the elevator system to work at undervoltages as low as 60%.

Title: Device for raising and supporting the foundations of a building
Inventor: GOSSELIN CONRAD
IPC: E02D31/00
Filed: 1990-11-28
Granted: 1996-04-16
Abstract: Stabilization   of    sagged   building foundations is carried out by raising and supporting these concrete foundations.   To that effect, an L-shaped lifting assembly is bolted to the concrete to support the foundations.   This lifting assembly is also formed with a vertical tubular member in which a tubular pile can slide longitudinally.  An assembly of two pivotal jaws, positioned on opposite sides of the pile, is mounted above the lifting assembly. In order to drive the pile into the soil, a pair of hydraulic cylinders interconnect the lifting and jaw assemblies. As the cylinders extend, the jaws pivot to enable the jaw assembly to slide upwardly over the pile.  As the cylinders retract, the jaws pivot to grasp the pile and drive it into the soil.  When the lower end of the pile reaches soil of sufficient hardness,  further retraction  of  the hydraulic  cylinders  raises  the lifting  assembly  and accordingly the  foundations. When the foundations have been adequately raised, the pile and the tubular member, both made of steel, are welded together to stabilize the foundations.

Abstract: When transferring data, an electronic document or the like from a first computer system (100) to a second computer system (200) via a data transmission line (300), e.g. a public data transmission line, a first output and input station (122) comprising a first electronic card (124) and a second output and input station (222) comprising a second electronic card (224) are used. The data is transferred to the first electronic card (124) from the first computer system (100) via the first station (122) and is encrypted in the first electronic card (124), whereupon they data is output from the first electronic card (124) in encrypted form and transferred via the first station (122) to the first computer system (100) and therefrom to the data transmission line (300). The data is received by the other computer system (200) in encrypted form and is transferred to the second electronic card (224) via the second station (222), whereupon the data is decrypted in the second electronic card (224) and is output from the second electronic card via the second station (222) to the second computer system (200). As the data transfer between the first and the second computer system is carried out between the first and the second electronic card, no third parties have neither authorized or unauthorized possibility of interfering with the data transmission and possibly changing the data or the electronic document. The first and the second electronic card (124, 224) constitute a coherent set of cards comprising coherent encryption/decryption keys input into the internal storages of the cards.

Abstract: A scroll chuck for holding a workpiece in a lathe includes a jaw holder having a front side and a rear side,  radially extending slots in the front side and means for attaching the holder to the lathe for turning about a central axis.  Two or more jaw devices are mounted in the slots and are radially movable therein.  A scroll member is rotatably mounted on the holder and has a spiral-shaped rib formed on a front surface thereof.  This rib extends along recesses formed on the jaw devices whereby rotation of the scroll member causes the jaw devices to move in the radial direction.   A pin member is arranged on  one  of  the  jaw devices  and extends  from a rearwardly facing surface of the device and into an elongate recess formed in the holder.  This pin member prevents the jaw device from accidentally disengaging from the holder.

Abstract: An mounting arrangement of a tool holder in a machine tool comprises a main shaft and the toool holder each having an extending end face formed by extending a given reference end face of the main shaft and a given collar end face of the tool holder, toward one another, respec-tively, both of which end faces are normally separated with a prescribed clearance, with required extensions so as to come into contact with one another  when  a tapered shank of the tool holder is fitted into a flared hole of the main shaft, so that the tool holder can be mounted in the main shaft securely owing to a high degree of integra-tion, without the occurence of friction due to the phe-nomenon of a fretting corrosion or the like in the contact surfaces between the flared hole and the tapered shank.          Such a high degree of integration of the main shaft and the tool holder enables a deep cutting to be readily performed in relation to a workpiece.    In addition,  the arrangement can be used compatibly with a tool holder of a normal product  or a main shaft of a normal product.

Abstract: A hydraulic system includes a hydraulic pump which provides pressurized fluid at an output port as a function of pressure in a load sensing port, a hydraulic reservoir, and a load pressure sensing line connected to the load sensing port. A solenoid operated implement control valve controls fluid communication to and from a hydraulic function such as a cylinder.  A supply control valve has a first position wherein the reservoir is communicated with the load sensing port and a second position wherein the pump output port is communicated with the load sensing port.  A spring urges the valve member to its first position, and a solenoid is energizable to move the valve member to its second position.  The solenoid is energized when the implement control valve is activated so that the supply control valve communicates pump pressure to the load sensing port and the pump will operate at full capacity whenever the second hydraulic function is operated.
