Abstract: SINGLE READ STATION ACQUISITION FOR CHARACTER RECOGNITION To read characters printed on a document it is transported beneath a self-scan photocell array extending substantially the entire width of the document.  Output signals from the photocells of the array are scanned by a plurality of channels, amplified and converted into a digital data format representing the character patterns.  The digital data is then processed to memory electronics and search electronics to select lines of character pattern data for transmission to a character recognition unit.  The search electronics compresses the character data into search segments to evaluate the top and bottom position of character lines.  Further, the search electronics determines line linkages between the elements of one search segment of compressed data and the elements of the preceding search segments for future processing in a line tracker. The line tracker provides signals to extract character lines from a temporary storage for transmission to a line block memory.  When the parameters of selected lines are determined by the line tracker of the search electronics the character data in the line block memory is unloaded into circuitry that functions to select data to be routed to read electronics for processing to a character recognition unit.

Abstract: In an air cleaner device for removing dust or other particles from air, and including a filter system of a circular line of filter bags through the walls of which the air is forced into the interior of the bags, an apparatus for removing accumlations of filtered-out particles adhering to the outer surfaces of the filter bags by introducing a flow of cleaning air in the reverse direction into the interior of the filter bags. The particle removing apparatus includes a circular line of tubes connected to a source of cleaning air and spaced from and registering with the top ends of the filter bags. The open ends of the tubes are closed off and sealed by a sealing plate which is motor driven for slow rotation. An aperture in the sealing plate is positioned to register with the ends of the tubes so that the latter are uncovered successively as the plate rotates, permitting a flow of cleaning air to be directed into the interiors of the filter bags and dislodge the accumulation of particles on the outer walls thereof.

Abstract: The mobile continuous mixer for the continuous production of low-viscosity bituminous mixed materials has a horizontally arranged mixing trough which has a material inlet and arranged in which there are two shafts (8) which run parallel to one another, are driven so as to contrarotate and are fitted with mixing blades (14) as mixing tools. The mixing blades (14) are predominantly pitched in such a way that they convey the material to be mixed along the mixing trough to an outlet provided at an end face. The remainder of the mixing blades (14) are pitched, especially in the material inlet zone, so as to convey against the main flow of the material to be mixed. In order to achieve optimum homogenisation of a wide range of mixing components over a short mixing distance, the circumferential speed of the mixing blades (14) joined to the mixing shafts (8) can be set to be more than 5 m/sec at their free ends. In addition, the diameter of the intersecting envelope circles (H) formed by the mixing blades (14) arranged at the mixing shafts (8) is about 1.5 times the axial distance (A) of the mixing shafts(8), the trough radii (R) about 0.75 times, and the width (B) about 2.5 times. At the same time, the length (L) of the mixing trough (4) is about 2.4 to 3 times the mixer width (B). <IMAGE>

Abstract: An index signal amplifier arrangement is disclosed for use in a beam index color television receiver of a type which includes a picture reproducer having index stripes disposed to be scanned by an electron beam and a photodetector for detecting when respective index stripes are scanned by the beam to produce an index signal. A local oscillator generates a local oscillating signal which is mixed with the index signal produced by the photodetector. The mixed signal is amplified by a band-pass amplifier, the latter preferably being formed of a band-pass filter having a predetermined, limited pass-band characteristic substantially centered on the expected frequency of the mixed signal, and a limiter amplifier coupled to the band-pass filter for removing amplitude modulations from the filtered mixed signal. Another mixer is coupled to the band-pass amplifier and also to the local oscillator for mixing the amplified mixed signal with the local oscillating signal to produce an amplified index signal having the index frequency. If the local oscillating signal frequency can be adjusted to "match" the particular picture reproducer which is used in the color television receiver, then the frequency of the mixed local oscillating and index signals will be constant from one picture reproducer to the next. Consequently, a standardized, or uniform band-pass amplifier may be provided for all picture reproducers.

Abstract: A tuning control system includes a pulse converter for converting a digital word to a corresponding pulse signal having pulses the width or frequency of which represents the magnitude of a tuning voltage associated with a respective channel. The pulse signal is applied to a filter which produces the tuning voltage. An automatic fine tuning (AFT) voltage is generated by an AFT discriminator in an IF section and also applied to the filter to modify the magnitude of the tuning voltage to correct for any frequency deviation of the IF signal. To make the response of the tuner to changes of the AFT voltage more uniform for different channels, the AFT voltage is applied to the filter through a switch which is selectively closed in response to the pulses of the pulse signal so as to change the effective amplitude of the AFT voltage applied to the filter as a function of the channel selected.

Abstract: The system has an electronic receiver/controller and a remote actuator/transmitter incorporating an encoder having a set of different codewords corresponding to the unlocking signal, sequenced in cyclic order (1,2,...x,...,n). At each actuation, one of these codewords is transmitted, in sequence, the x-th actuation transmitting the x-th codeword. The receiver has a decoder, which counts the transmissions and only converts the x-th transmission into the unlocking signal, releasing the electronic controller if it is the x-th codeword, these cycles continuing until x=n and then returning to x=1 and recommencing. If synchronism between the encoder and decoder is disturbed, it is restored by a signal from an auxiliary encoder having a set (m) of different, auxiliary, sequenced codewords acting as synchronisation signals. When the transmitter is specially actuated, one of these auxiliary codewords is transmitted, in sequence, the x-th actuation generating the x-th auxiliary codeword. An auxiliary decoder in the receiver counts the transmissions and converts the x-th auxiliary codeword on receipt into the unlocking signal, bringing about synchronisation and also switching the receiver to the (x+ 1)th auxiliary codeword (which the transmitter is prepared to emit), until at x=m the cycle recommences at 1.

Abstract: A method of manufacturing a bottle cap provided with a ring-pull is disclosed, in which a band is cut from a metal strip by shears and is simultaneously curled up, by shear bow, to form a cylindrical band with overlapping ends, while a bottle cap portion with a tab is prepared separately from another metal sheet. Then, the cylindrical band is firmly connected to the tab of the cap by rolling the cylindrical band up from one edge, to form a toroid while rolling the tab up into the band. The method may be carried out using apparatus including a transporting turret for transferring the cylindrical band to a pulling ring former for forming the pulling ring, a feeder for feeding the bottle cap to a turret anvil carried by the turret; a pressing device for urging a bottle cap tap against the cylindrical band; a roller mechanism for rolling the bottle cap tab and the cylindrical band up to form the pulling ring while joining the latter to the bottle cap; and a device for embossing the region of the joint between the pull-ring and the tear tab. The invention allows bottle caps with ring-pulls to be produced on a mass production basis with minimum loss of material.
