Abstract: 1528377 Pseudo halftone printing INTERNATIONAL BUSINESS MACHINES CORP 15 Oct 1975 [20 Jan 1975] 42145/75 Heading H4F [Also in Division G4] A method of operating a matrix printer selectively operable to print a mark at any of n matrix positions in a print area to produce a pseudo halftone copy of an original from a sequence of signals, each signal representing the tone or grey level of a respective incremental area of the original, comprises using a random number generator to select on a chance basis one of n numerical values, establishing from the randomly selected value an order of the matrix positions such that marks have to be printed at the first p positions in the order to produce a tone level p, 0#p#n; and printing p marks at the first p positions in the order to produce a print area having a tone level p necessary to produce a tone level corresponding to that of an original incremental area being reproduced. It is stated that this method avoids the production of MoirÚ fringe patterns. Examples of dot patterns produced by a 4 x 4 matrix printer are shown in Fig. 9: these are produced by comparing 10 a grey scale input with the output of a randomly initialized modulo-N<SP>2</SP> counter 18-19 repeatedly incremented by N, and printing at a matrix position if the level is greater than the counter output.

Abstract: A method is described for increasing the yield limit and the density of polyethylene terephthalate and other similar thermoplastics, which have a tendency to harden under strain. The plastic material is conditioned to a temperature within a range that promotes molecular orientation, and is then mechanically conditioned by being stretched at first in one direction to a length which is at least around 2.6 to 2.75 times the original length. After this, the plastic material is stretched in a second direction, and hardening during elongation and strain-induced crystallisation drastically increase almost immediately after the commencement of the second stretching stage by virtue of the mechanical conditioning by the elongation during the first stretching. The invention is especially suitable for forming of blow- moulded containers, where a preform or a workpiece is first stretched along its longitudinal axis to a critical length and then strain-hardened to a large extent while the blow-moulding to shape the container is occurring. <IMAGE>

Abstract: Method of separating a molten hypoeutectic alloy comprising a base metal A and an alloying element B into two melts, namely a melt comprising solely pure A and a melt comprising a B-enriched alloy with B-contents up to the eutectic composition. The melt is introduced to a bath which is located in an elongate reactor vessel and the temperature of which varies from one end of the vessel, a warmer end at which the temperature is immediately above the melting point of the base metal A, to the other, colder end of said vessel, at which the temperature lies above the liquidus temperature of the desired B-enriched alloy, and in which the temperature of the bath in the intermediate parts of the reactor vessel lies close to the liquidus line in a phase diagram A-B and the composition of said bath varies from substantially pure A at the warmer end of the vessel to a given B-enrichment at the colder end of the vessel. Metal crystals having a lower B-content than the bath are precipitated by internally cooling the bath in intermediate parts of the vessel, and the precipitatedcrystals are caused to move towards the warmer end of the reactor vessel, whereat because the crystals must constantly be in equilibrium with a bath which is progressively poorer in the alloying element B are progressively depleted of the alloying element B, so that a substantially pure base metal A can be taken out at the warmer end of the vessel. A B-enriched melt is simultaneously caused to move towards the colder end of the vessel, whereat A-enriched crystals are constantly formed, so as to enable a melt having the given B-content to be taken out at the colder end of the vessel. The amount of base metal and alloying element removed from the system is replaced by supplying fresh starting material to the reactor vessel at a location where the composition of the bath is the same as that of the starting material, and the temperature of the starting material is regulated to the temperature prevailing at this location.

Abstract: The invention relates to centrifuging devices, and particularly to the acceleration thereof to a design speed. In order to prevent imbalance (U) of the device exceeding a permitted maximum value (Um) during acceleration, the imbalance (U) is monitored and acceleration ( alpha ) controlled as a function of temporal changes in the imbalance (U). Acceleration n/t may be controlled in relation to the difference ( DELTA U) between the measured imbalance (U) and the maximum value (Um), in relation to the rate of change ( beta ) of the measured imbalance, or to maintain the imbalance (U) between upper (U1) and lower (U2) threshold values at or below the maximum value (Um). Acceleration to the design speed can thus be accomplished with minimum delay and variation with reference to operating criteria of the device.
