Abstract: A thermal dye transfer printing process for making transparent prints, which comprises bringing a dye-bearing donor ribbon (17) in contact with a dye-receiving polymer print sheet (15) at a print zone, supporting both materials on a backing support (14) in said zone and contacting the donor ribbon with a print head (18) for image-wise heating the ribbon and cause dye transfer to the print sheet, wherein the rear side of the print sheet is uniformly heated on a drum (30) after removal of the sheet from the backing support, thereby to reduce curling of the sheet caused by the image-wise heating of its front side.

Abstract: A method for generating a screened reproduction of a multiple tone image comprising the steps of frequency modulation screening the multiple tone image to obtain screened data representing tones of the multiple tone image in terms of halftone dots, reproducing the halftone dots on an imaging element by means of a scanwise exposure, characterized in that the scanwise exposure for rendering a halftone dot is time modulated.

Abstract: A two-stroke internal combustion engine in a working machine such as a chain saw has been prone to stalling when the stance of the machine was changed from slanting down to slanting up. Such stalling is minimized when lower longitudinal scavenging passage in the cylinder block of the engine have smaller cross section as compared with upper scavenging passage, and when the crank chamber of the engine includes a flow restricting portion for impeding the flow of liquid fuel into the lower scavenging passage when the stance is changed. The engine has a cylinder block (12), a crankcase (20), scavenging passages (27, 27), and a flow restricting portion (40) on an inner peripheral surface (22a) of the crank chamber (22).

Abstract: The invention relates to a method and a plant for manufacturing mineralized portland cement clinker. The method and plant provides for preheating, calcining, burning and finally cooling the clinker. The mineralizer may e.g. be gypsum, fluorine, or a waste product containing these or other mineralizers. The mineralizer is added to the feedstock after the feedstock has been fed to the process, preferably after the cyclone which handles the feed to the calciner, i.e. the last cyclone in the preheater, or the lowermost preheater stage in a plant which does not incorporate a calciner.

Abstract: To prepare cellulose fibres, a solution of cellulose in a tertiary amine-oxide is shaped in hot condition to give filaments, the filaments are cooled and then introduced into a precipitation bath in order to precipitate the dissolved cellulose, whereby the shaped solution is exposed to an essentially laminar gas stream (FIG. 2a) for cooling before introduction into the precipitation bath.

Abstract: An electromagnetic relay, such as an electromechanical RF switch, which is operated by an electromagnetic coil, is provided with an indicating circuit which responds to the position of the electromagnetic armature as well as the application of driving current to the coil. A magnetically activated reed switch is mounted adjacent to the electromagnetic coil at a distance selected so that the magnetic field of the coil will operate the reed switch when current is applied to the coil and the armature is driven into a position closing a magnetic circle.

Abstract: A safety device in a lighting rod comprises a locking member having an engagement section, which interferes with a portion of an operation member and thereby locks the lighting operation of the operation member. The locking member can move in a direction, that intersects with the direction along which the operation member moves. An urging member urges the locking member to a locking direction. The locking member is provided with a lock releasing section, which can be operated in order to move the locking member in a direction, that acts against the urging force of the urging member. The lock releasing section is projected to a position, which stands facing the operating section of the operation member. The lock of the lighting operation is released by operating the lock releasing section of the locking member, and the locking operation is carried out in this state by operating the operating section of the operation member.

Abstract: A lightly doped drain (LDD) metal oxide semiconductor field effect transistor (MOSFET). Field oxide is used as a hard mask for a total-overlap polysilicon (TOP) gate which minimizes hot-carrier degradation, so that a soft-mask step is saved. The field oxide is used also as a hard mask for surface counter-doping which reduces gate-induced drain leakage, and in making a punch-through stop which reduces drain-induced barrier low and short channel effect.

The compositions are useful in a method of anesthetizing cornified skin comprising topically administering the subject compositions. The present compositions and methods permit rapid and effective anesthesia of cornified skin, such that various surgeries and interventions can be performed without the need for subcutaneous injections of local anesthetics. The present invention further provides a compartmentalized kit having a first container providing emu oil and a second container providing an aqueous solution of lidocaine.

Abstract: A method for applying an ink-receiving layer to any given substrate comprising the steps of laminating a sheet or web material comprising at least three layers which include a temporary support having a thickness between 40 and 100 .mu.m, an ink-receiving layer and an adhesive layer onto said given substrate, and stripping the temporary support away to free the ink-receiving layer. The ink-receiving layer, according to the present invention, is adapted to be used with water-based inks and enables the end-user of said image-recording member to transfer that ink-receiving layer to any one of the substrates of his choice.

Abstract: A method for packet signalling between a base station with a variable antenna system and remote stations uses pilot tones sent by the remote stations to the base station at the start of each data transfer period in which signalling will occur in either direction. The base station uses the pilot tone to configure the directional antenna for communication with the remote station during that data transfer period. The pilot tone signals are initiated by polling signals and polling acknowledgment signals.

Abstract: A coextrusion system employs two or more extruders, each with a gear pump at its output connected to a coextrusion die. Different materials are extruded by each extruder. Varying the speed of one or both gear pumps varies the content of the extrudate. The gear pumps permit precise variation of the relative content of the materials extruded by the several extruders lengthwise along the extrudate. A display of a cross sectional dimension of the extrudate along a length of the extrudate permits observation of the lag that occurs between alteration of gear pump speed (or air pressure in the case of tubular or blown sheet extrudates) and the resultant change in dimension, so that a speed correction can be made at the appropriate time to compensate for differing shrinkage and stretching characteristics between the several extruded materials.

Abstract: A novel pyrimidine derivative, N-(2-amino-4,6-dichloropyrimidine-5-yl)formamide for use, e.g., in the production of antiviral nucleotide derivatives, can be made by a process involving cyclyzing an aminomalonic ester with guanidine or its salt in the presence of a base to produce 2,5-diamino-4,6-dihydroxypyrimidine or its salt, chlorinating this product with a chlorinating agent in the presence of an amide to produce 4,6-dichloropyrimidine, and reacting the 4,6-dichloropyrimidine with an aqueous solution of a carboxylic acid to produce the N-(2-amino-4,6-dichloropyrimidine-5-yl)formamide.
