Title: System for mixing beverages
Inventor: ASCHBERGER MATTHIAS
IPC: B01F15/04
Filed: 1985-08-06
Granted: 1990-01-24
Abstract: The beverage mixing appts. comprises an outlet shut-off valve (14) controllable by a timing control equipment (13) and a flowcontrolling valve (15) regulating a constant flow rate independently of the pressure of the supplied liquid.  The flowcontrolling valve includes a piston chamber with a dispalceable piston (25), which divides the piston chamber into two partial regions (24,28).  A flow throttle path (27) is formed on the piston between the two regions.  In the first partial region an invariable flow entry opening (23) is formed in the direction of which the restoring force acts.  A flow exit throttle (29) variable in cross-section by the piston stroke setting is prepared in the second partial region.

Title: Device and method for measuring localized deformation or strains of structure
Inventor: LEE JAE-KYONG
IPC: G01N21/41
Filed: 1986-06-05
Granted: 1989-07-18
Abstract: The components of the plane strain are continuously measured under the loading on the structure by using a laser beam instead of a surface contact.  A diffraction grating is formed on the surface of a specimen and a laser beam is applied onto it.  An interference pattern is analyzed with the diffracted laser beam passing through the passageways of odd numbers of mirrors, a lens and a beam splitter by two pairs of screens comprising three phtosensors.  Then the components of plane strain is calculated by substituting the obtained data into the empirical equations induced from this invention.

Abstract: The apparatus scans  and  sending  the  next  halted  message without the manuscript skip, which is caused by the power failure. A manuscript position sensor (6) checks the manuscript  existance. If the sensor  does  not  detect  it,  a  sensor  (5)  checks  the manuscript existance again. If no, the operation stops; otherwise, it is determined that the manuscript is the first one, and feeding and main rollers  are  driven.  When  the  sensor  (6)  detects  a manuscript,  the  manuscript  is  fed  to  a  manuscript  scanning position (7). And the sensor (6) checks the  manuscript  existance to stand by for operation. If yes, the message is transmitted, but if no, only the scanned message. When the sensor (5)  detects  the manuscript, the operation repeats, but the manuscript  is  fed  to the main roller only when no manuscript is detected.

Title: Method and apparatus for winding web
Inventor: SNYGG KEIJO
IPC: B65H19/30
Filed: 1989-07-04
Granted: 1995-06-14
Abstract: The invention relates to a method for on-machine winding of a web (W), in which method a Pope-type reel drum (10) or corresponding reeling means is used and over which the web (W) to be wound is conducted. In the method, new reel spools (11) are brought into contact with the reel drum (10), after which the web (W) is conducted from the fully wound roll to be wound onto the new reel spool (11). In the method primary forks (14), when in their upper position, pick up an empty reel spool (11A,11B) without any auxiliary equipment. Guided by the primary forks (14) and supported on support plates (17) attached on the primary forks (14), the empty, preaccelerated reel spool (11B,11C), is brought into nip contact with the rotating reel drum (10) and through the nip of which the web (W) to be wound runs, and is wound round the reel spool (11) at the nip contact. The support plates (17) remain in such a position while the primary forks (14) are being lowered that the contact pressure between the reel spool (11C-11E) and the reel drum (10) remains substantially constant while the primary forks (14) are moving from the upper position to the lower (see vector diagrams, Fig. 2). When the primary forks (14) are in the lower position, the support plates (17) turn into such a position that they may pass the reel spool (11), which is already positioned on the reeler tracks (12), when the primary forks (14) are moving back into their upper position, and the above steps are repeated when it is time to exchange reel spools (11) again and the support plates (17) are ready to receive one. The invention also relates to the apparatus used in the method.

Granted: 1992-06-26
Abstract: When a switch board number is designated, a decision is  made on whether  an  overflow  distribution   method   or   an   equal distribution method is to be selected. If  an  equal  distribution method  is  selected,  it  is  executed,  and,  if   an   overflow distribution method is selected, a checking is made on whether  it is a day mode. If it is a day mode, a checking finds whether it is a free loop. If there is no free loop, the number of overflows and the number of busy lines are compared with each  other,  while  if they are equal to each  other,  the  number  of  switch  board  is incremented. The method distributes calls in an equal manner.
