Abstract: A doctor arrangement for a rotary intaglio printing machine comprises a doctor to remove excess ink from the plate cylinder. The doctor is in the form of a band which extends parallel to the axis of rotation of the plate cylinder against which it is pressed by a doctor bar. The doctor band is so flexible that it can be wound on and unwound about axes which extend transversely to its longitudinal direction and the doctor band is so mounted and guided at the doctor bar that it is displaceable relative thereto in the longitudinal direction, the length of the doctor band being substantially greater than the axial length of the plate cylinder. A respective winding device for winding on and unwinding the doctor band is arranged in the region of each of the axial ends of the plate cylinder. A drive means displaces the doctor band along the doctor bar during the printing operation when the doctor band is unwound from the one winding device and wound on to the other winding device.

Title: Apparatus for treating fiber suspension
Inventor: ALAJAEAESKI TIMO
IPC: D21D5/06
Filed: 1993-04-08
Granted: 1997-08-19
Abstract: The present invention relates to an apparatus for treating fiber suspension. Theapparatus in accordance with the present invention is especially suitable for screening pulps and also for thickening. More accurately, the apparatus relates to the pulse member construction of the screen or thickener being used. It is characteristic of all pulse members in accordance with the prior art that when the capacity of the screening apparatus in increased, for example, by using greater pressure differences or the cleanliness of the accept is increased by decreasing the size of the perforations or slots, this results in a situation, in which the screen cylinder tends to clog. The problem is thus keeping the screen cylinder clean, which is a precondition for optimizing other features in the screening. The present invention relates to a pulse member (P) of the screening apparatus, which is characterized in that the screen surface is subjected thereby with members (60) to a pulse cleaning the screen surface without a chance to allow the pressure effect "escape" past the area being cleaned. It is also typical of the pulse member in accordance with the present invention that the higher the consistency of the fiber matting is or the worse the screen surface is clogged, the stronger the pulse cleaning the screen surface is.

Abstract: The transfer of data packets are monitored in a line having various logical channels. For each logical channel there is a count value (L i) and at the arrival of a data packet or in each time slot, when the transmission on said line is time multiplexed, i.e. for each tame, when a packet could have arrived in a time multiplexed system, only said count value (L m) for a single channel (m) is decremented.      Then it is determined whether said received data packed, if there is one, is to be forwarded or is to be lost, by the comparison of a calculated value (F n) to a threshold value (T n) belonging to the channel (n), to which said packet belongs. In the calculation of said discrimination value (F n) the number of those channels is used, which have not been decremented after decrementing the channel (n), to which the received packet belongs. In this way the calculated value (F n) can be made to resemble the calculated value or level value, which is used in prior methods for handling loss of packets in a network. For each received packet this method requires only a decrementing of one count value (L n), implying a significant saving of time and a simplification of the circuits used for carrying out the method.

Title: Removing the effects of acoustic ringing and reducing temperature effects in the detection of explosives by nqr
Inventor: BUESS MICHAEL L
IPC: G01N24/00
Filed: 1993-10-25
Granted: 2002-02-12
Abstract: Acoustic ringing and adverse effects from variations in the NQR detection of explosives and narcotics are minimized or eliminated. A specimen (1) is irradiated with a modified shady state free precession (SSFP) pulse sequence which combines a phase-alternated pulse sequence (DAPS) with a non-phase-alterned pulse sequence (NPAPS). The resulting signals from the PAPS and NPAPS may then be coadded to cancel out the FID contributions to the signals. By canceling out the Fm contributions to the signals, the effects of probe ringing and other extraneous responses, as well as the effect of temperature variation, arc minimized or removed. The present method is especially effective in the detection of explosives and narcotics having 14N  or 35,37C1 nuclei. A steady state free precession pulse which is especially useful with the method of the present invention is the strong off resonance comb (SORC). In another embodiment of the invention, the effects of probe ringing can also be minimized or removed by repeating the detection procedure at a frequency which is sufficiently off-resonance so that only frequency independent effects, such as probe-ringing, can be observed.

Abstract: A plastic looped handle has a front ring with two parallel members connected by a front brush head member. Bristles in curved rows extend from one side of the brush head for brushing of teeth, while convex protrusions extend from the other side of the brush head for tongue cleaning. A center bar extends across the front ring, and a rear ring extends rearwardly from the center bar.  A front opening is defined between the front ring and the center bar and a rear opening is defined between the rear ring and the center bar. Both openings are sufficiently large to receive at least two human fingers therethrough. The center bar defines an angle with one of the front members of less than 90 degrees, to thereby define a wedge space, into which the hand of a user may be inserted and wedged to thereby retain control of the toothbrush. The two front members are spaced from one another a width to permit the insertion of the brush head into a user's mouth, while the rear ring is substantially wider than the front ring, to thereby permit the support of the brush within the non-extended fingers of a crabbed hand. The brush is particularly suited for use by those who have lost some gripping abilities, and by those who must brush the teeth of others. In addition, by providing black bristles, the brush may be used to brush the teeth of pets.

Abstract: Pharmacological agents active at the level of gene transcription are identified in high throughput drug screening assays. The methods involve combining a labeled transcription factor, a nucleic acid coupled to a ligand, a candidate pharmacological agent and a receptor immobilized on a solid substrate, such as a microtiter plate, filter, or bead. The nucleic acid has at least that portion of a nucleotide sequence naturally involved in the regulation of the transcription of the gene which is necessary for sequence-specific interaction with the transcription factor. The resultant combination is incubated under conditions whereby the receptor is bound to the ligand and, but for the presence of said candidate pharmacological agent, the transcription factor is sequence-specifically bound to the nucleic acid. Unbound transcription factor is then removed or washed from the solid substrate and labelled, sequence-specifically bound transcription factor is detected. Incubates which include candidate agents which alter transcription factor binding deviate from control incubates in terms of label signal - typically, binding is disrupted and the signal is diminished. In a preferred embodiment, the entire process is performed by a computer-controllable electromechanical robot with an axial rotatable arm.
