Title: A vending machine for complete meals
IPC: G07F11/62
Filed: 1988-12-20
Abstract: A vending machine which, after payment of a fee, delivers a 
complete meal from a number of meals which are available through 
the manipulation of selector means (19). Each of said meals 
comprises two or more articles of food packaged in separate 
units (18a-18j), which units are stored in different compart­
ments (17) in said machine. The compartments are placed on 
different levels within the machine. The selection means (19) 
comprises a traveller (26) which can be displaced along a U-­
shaped arm (29) which is journalled on a horizontal axis (27) so 
it can be pivoted by drive means until the traveller (26) is in a 
position to cooperate with one of several coaxially journalled 
elevator frames (32a-32f). The elevator frames are mechanically 
connected to different feeding out means (35a, 35b) which are 
arranged at each respective compartment level.

Patent EP-0334312-A3 (EP)
Title: Method and apparatus for improving the operation of a disc filter
IPC: D21D5/04
Filed: 1989-03-22
Abstract: The present invention relates to a method and an apparatus 
for improving the operation of a disc filter. In 
particular the invention relates to increasing the discharge 
consistency of fiber suspensions treated with disc filters 
in the paper and pulp industry.  
     As is known the consistency of a fiber suspension can be 
raised with disc filters to approx. 16 % measured on a 
filter disc. However, when a cake of pulp is detached 
from the filter surface the detaching water jet reduces 
the consistency to approx. 12 % measured in the pulp 
discharged from the thickener. In all prior art devices 
the detaching liquid jet is continuous and liquid is sprayed 
onto the filter surface even though the pulp cake already 
has been detached or would be detached from the filter 
surface by itself due to the force of gravitation. This 
results in unnecessary dilution of the pulp.  
     In order to avoid the above mentioned drawback a method 
and an apparatus (11, 12, 13, 14) have been developed with 
which the detaching liquid jet sprayed from a nozzle (7) 
is made intermittent so as not to add unnecessary liquid 
to the pulp. This increases the consistency of the pulp 
discharged from the thickener at least by 2 % which is a 
remarkable advantage both for the operation of the thickener 
itself and also for the operations subsequent to the 
thickening.

Title: Method of and apparatus for recording halftone image
IPC: H04N1/405
Filed: 1989-04-12
Abstract: An image scanner for producing a halftone image is 
provided with a halftone signal generator (1) for generating 
an exposure signal (S) controlling exposure time of a laser 
beam (L) focused on a photosensitive material (17). The 
halftone signal generator is so constructed that image data

elementary area is determined mainly according to a 
difference between the image data and the threshold data. 
Accordingly, some elementary areas are exposed divisionally 
in proportion to the exposure time.

IPC: H03M1/00
Filed: 1989-04-25
Abstract: A plural channel indirect digital to analog 
converter. Words containing address bits and data 
bits are received on an input and entered into a 
specific one of the converter channels under control 
of the address bits of the word. The data bits are 
applied to a binary rate multiplier of the channel 
which generates a pulse modulated output signal 
representing the binary value of the received data 
bits. The pulse modulated output signal is applied 
to an associated filter which converts the pulse 
modulated signal to an analog output signal whose 
amplitude represents the binary value of the 
received data bits. Gating circuitry ensures that 
each output pulse is of a precisely controlled pulse 
width. One of the converter channels is used to 
calibrate the output level of the filters. The 
number of data bits applied to the different 
channels may need not be the same and may vary in 
number from a minimum of 1 to a maximum of m.

Title: Sulfite modified continuous digesting
IPC: D21C7/00
Filed: 1991-05-22
Abstract: In the production of paper pulp by the sulfite pulping process, the amount of sulfite cooking chemical consumed per ton of pulp produced is significantly lowered, a much lower K-No. can be achieved without screen plugging, the wash circulation temperature is lowered, and the digester (19) runs better, in the practice of the invention. According to the invention, the wood chips entrained in sulfite cooking liquor are fed into the top of a digester, and flow co-currently to a central portion (21) of the digester, at which portion waste liquor is extracted and passed to flash tanks (25). An effective amount of the sulfite cooking liquor (preferably about 5-20%) utilized for producing the pulp is introduced into the vessel in the wash circulation (36), adjacent the bottom of the digester, to flow countercurrently to the material moving downwardly in the vessel. The produced sulfite pulp is withdrawn (at 33) from the bottom of the digester. The invention is primarily applicable to acid or bisulfite pulping, but also can be utilized with alkaline or neutral sulfite pulping. In some circumstances the entire cooking flow can be countercurrent (e.g. 5% up to close to 100% of the sulfite cooking liquor flows countercurrently to the material). <IMAGE>
