Patent FI-97238-C (FI)
Inventor: KAISER HANS-GERD
IPC: C11D7/14
Filed: 1990-07-12
Granted: 1996-11-11
Abstract: The invention allows cleaning of poorly accessible machine parts, e.g. in the transport and or moulding of materials in the pasty state by addition of one ore more inorganic or organic solvent(s) and one or more inorganic or organic salt(s) which are soluble therein, preferably as a solution, to the material to be processed. The melting point of the salt(s) is above the processing temperature of the material. The boiling point of the solvent(s) is below the processing temperature of tie material. The invention finds its application in the changeover of material to be processed in plastic processing machines, such as, injection moulding machines, extruders and blow-moulding equipment by accelerating the removal of the previous substance from the plasticizer unit and the nozzle region; an analogous field of use is, e.g. in the operation of kneaders.

Abstract: A swing-and-slide door for vehicles, especially railroad passenger vehicles. The leaf is suspended at the top on a positioning bushing on a supporting rail that extends over the total width of the door. At the bottom of the door a horizontal positioning rail is secured to the leaf. A positioning section slides back and forth mechanically secured in the positioning rail. The securing rail and positioning section are secured to the studs of two cranks. The cranks are fastened vertically separated to the vehicle superstructure by means of horizontal shaft studs and cranks studs that extend parallel to the direction of displacement, are connected by a connecting section, and are driven by a pneumatic cylinder. The door is opened in a sequence of two stages. The leaf is first displaced out of the closed position into a ready-to-slide position and then slid horizontally to the side in that position. The bottom and top of the leaf are mechanically secured during both stages.

Granted: 2002-02-12
Abstract: The invention relates to a fibre optic measuring device of the type in which the change in a measured parameter generates a phase difference between two waves in a SAGNAC ring interferometer (2).      Electronic means (7) comprise a processing system (9) delivering a signal depending on the measured parameter and electronic means (12) controlling the phase modulator (4).      The electronic means (12) produce a control signal for the modulator determined in such a way that the phase difference 54m which it produces between the counter-propagating waves periodically takes the following four successive values: .delta.~1 = .delta.o                    .delta.~3 = a~o .delta.~2 = - .delta.o        .delta.~4 = - a~o where ~o is a constant phase shift and it depends on a, and a is a positive constant satisfying the condition: cos~o = cosa~o.      The gain of the channel for controlling the modulation is kept constant by producing a signal depending on the said gain by exploiting the four values x1, x2, x3, x4 delivered in response to a period of the modulation signal according to the expression (x1 + x3) -(x2 + x4), the said signal acting on the modulator in such a way as to keep the gain constant.

Granted: 1995-07-25
Abstract: A process for forming a moldboard blade for a grader by inducing beneficial residual stresses during fabrication. This increases the strength of the blade without adding additional material and weight.  The blade is first bowed towards its supporting structure surface.  The supporting structure is welded to the blade and the blade is released. The blade is then bent in the opposite direction towards its working surface and released.  The blade is then checked to determine if it is straight.  If the blade is not straight it is bent again until it is straight.
