Title: Method and an arrangement for the feeding of a material web
Inventor: GIACOMELLI PETER
IPC: B65B41/18
Filed: 1987-01-27
Granted: 1992-02-11
Abstract: ABSTRACT     In the stepwise feeding of a packing material web  for the application of cover strips over prepunched pouring openings, the pouring opening is sensed by means of a photocell which is located as long before the point of application as the distance between two pouring openings. Any errors in this distance will thus affect the accuracy of application. In order to avoid this it is proposed in accordance with the invention to sense the passage of the actual pouring opening  and    start a countdown sequence, at the end of which  the  web  feeds  interrupted  with  the  pouring  opening  in correct  position  for  the  application  of  the  cover  strip.    An arrangement for the realization of this, seen in the direction of feed of the material web    ,comprises a sensing device    , a processing device      and a forward feeding device   which are connected to a control unit.

Title: Internal batch mixing machines with non-intermeshing rotors of increasedperformance
Inventor: NORTEY NARKU O
IPC: B01F7/04
Filed: 1987-10-13
Granted: 1992-03-31
Abstract: ABSTRACT OF THE DISCLOSURE         Non-intermeshing four wing and three-wing rotors for use in high intensity mixing machines of the batch type provide new sequences and new characteristics of dynamic interactions for achieving advantageously increased mixing effectiveness and strength of the rotors.  These new rotors are adapted for driving at unequal speed (unsynchro-nized rotation) or at equal speed (synchronized rotation). In the four-wing rotors, long wings and short wings both originate from both ends of the rotor.   The new four-wing and three-wing rotors intensify axial and transverse distri-butive mixing for causing the mixes (batches) to become more homogeneous.   The markedly increased twist angles T in both types of rotors decreases the volume of material "sitting" at the center of the mixer for maximizing the dis-persive mixing or high shear occurring between wing tips and wall surface of each rotor cavity. The marked increase in helix angles A enhance distributive (blending) mixing by rolling banks of material in axial directions in the rotor cavities with components of axial movement and axial flow. The larger ratios of axial wing length to rotor length in-crease the propelling material from near the originating end of the long wing in an axial direction along the cavity over near to the other end of the cavity and then back again with back-and-forth zig-zag like motions for enhancing distribut-ive mixing and blending.  Randomization of blending is advantageously achieved by each rotor by rolling the banks of material back-and-forth with differing velocities in opposite directions.  The new interactions of these rotors produce numerous advantages and mixing features.

Title: Load spacing conveyor system
Inventor: LANGEN MARINUS J M
IPC: B65B35/24
Filed: 1988-04-21
Granted: 1991-08-06
Abstract: ABSTRACT A feeder mechanism for feeding load items in a predetermined spaced relationship into a loading station of a carton loading machine comprises at least two conveyors which move at different speeds along the same path and elevator ramps on each of the conveyors.  The primary conveyor has a forward run mounted for movement at a first predetermined speed in a forward direction.  The forward run hasg an input end for receiving load items and it extends forwardly from the input end into a spacing station.  The secondary conveyor has a forward run mounted for movement at a second speed in the forward direction which is faster than the first speed.  At least a portion of the forward run of the second conveyor is located adjacent and coextensive with a portion of the forward run of the primary conveyor in the spacing station. A plurality of elevator ramps are mounted on the secondary conveyor at longitudinally spaced intervals therealong.  Each ramp has a ramp face which is upwardly and rearwardly inclined in a direction opposite to the forward direction.  The leading end of each ramp is disposed at or below the level of the adjacent primary conveyor and the trailing end of each ramp being disposed at a level above the level of the adjacent first conveyor.  The ramps are aligned with load items supported on the first conveyor in use such that as the secondary conveyor accelerates the ramps with respect to the primary conveyor, the ramp face will pass under a load item and elevate it out of contact with the primary conveyor and thereafter transport the load items through the spacing station with successive load items being spaced from one another.

Abstract: DELAY QUANTIZATION TECHNIQUE TO REDUCE     STEERING ERRORS IN DIGITAL BEAMFORMERS     ABSTRACT OF THE DISCLOSURE    Quantized delay values used in a digital beamformer are selected so as to minimize the derivative of the beamformer pattern.  A first set of quantization error values, one for each hydrophone, is determined from the precise delay values and a second set determined by adding a shading factor times the sample period to each member of the first set.  Each set of combinations of member so the first and second sets of error values is then examined to determine which set minimizes the derivative of the beamformer pattern.  The quanitzed delay values are then determined by selecting the quantized delay value corresponding to the error value in the set which minimizes the derivative.

If the exhaust bridge      heats and expands into the cylinder , the piston will not rub on it.

Title: Sound reproducing apparatus continuously deriving reproduced sound signal at recording time while driving sound reproducing media in special reproduction mode
Inventor: ARAI TAKESHI
IPC: G11B20/04
Filed: 1988-12-15
Granted: 1993-04-13
Abstract: ABSTRACT           A sound reproducing apparatus is disclosed, which converts a sound signal reproduced in a 5 multiple speed reverse reproduction mode into a digital signal, by pulses obtained by frequency-multiplying reference sampling pulses by 5 to write the digital signal in a memory, and reads out from  the  memory  the  digital  signal  by  the  reference sampling pulses to convert the same to an analog signal.          Reading of the signal from memory is performed in response to  a  read  address  changed  in  one  direction  in  a predetermined cycle.  Writing of a signal to the memory is performed by using address  information changed  in the direction opposite to that of the read address signal at a speed five times that of a read address signal as a write address in a cycle corresponding to five-sixth of the cycle of the read address,  signal,  and only during a period corresponding to one-sixth of the cycle thereof.   Thus, writing is performed with the address being reversed, so that a reproduced sound signal which is considerably long continuous can be derived without interruption even in the reverse reproduction mode.
