Abstract: In all forms of straightening unbalanced workpieces, the existing fatigue strength, or fatigue strength achieved by prior processing, of the workpiece to be straightened is impaired by the straightening operation. It is the intention of the invention to propose a straightening operation which prevents this. This is achieved by virtue of the fact that internal compressive stresses are introduced locally into the workpiece by compaction in the region of the boundary surface, the respective unbalance of the workpiece to be straightened thereby being at least reduced. The introduction of internal compressive stresses into the region of the boundary surface of the workpiece can be achieved by a localised hardening operation or roll- hardening operation. By varying the intensity of hardening or of roll- hardening, the magnitude of the straightening effect, i.e. the magnitude of unbalance and the direction of unbalance, can be influenced.

Abstract: A vibratory seismic surface source includes a single vibrating mass, the energy of which is coupled with the earth through a ground contacting base plate. The vibrating mass is connected to the base plate by means of a ball and socket joint which constitutes a universal pivot for the vibratory axis of the mass. Thus, this vibratory axis may be made to assume any vector path with respect to a seismic line. In this manner, any desired combination of compressional and shear waves, both SH and V type, may be generated and recorded simultaneously at a point on the earth's surface remote from the source.

Title: A Lens
Inventor: NELSON JOHN C
IPC: F21V5/00
Filed: 1987-03-06
Abstract: A lens of a transparent material including a structured surface on oneside and a smooth surface on the opposite side. The structured surface includes a plurality of three-faceted prisms arranged side by side to form a plurality of ridges and grooves. Each prism has a reflective surface adjacent to a refractive surface and a riser adjacent to the refractive surface. The surfaces are angled with respect to one another so that incident light is transmitted through the lens, whereby the exiting rays may be predisposed to be perpendicular or non-perpendicular. Because of this the lens can be used to disperse, collimate, gather or concentrate the light. Thus, it may be utilized in a variety of ways, for example, in a light fixture, whereby high-angle incident light directed toward either the structured surface or the smooth surface, is transmitted through the lens and is directed in a desired fashion.

Abstract: A processor and auxiliary processor for use in a digital data processing system, the auxiliary processor processing selected instructions, such as floating point instructions. The processor and auxiliary processor are interconnected by status lines, data lines and a bus to which other units in the system may also be connected. When the processor begins processing a selected instruction, it passes the instruction's operation code to the auxiliary processor over the data lines and enables the operands to be transferred to the auxiliary processor over the bus, along with information concerning each operand, which is transferred over the data lines. The processor then signals over the status lines that it is ready to receive the results. The auxiliary processor, when it has finished executing the special instruction, transmits a code over the status lines indicating it is sending the results, and transmits the condition codes over the data lines and the result data over the bus.

Abstract: A process of producing a room temperature-stable solvent solution from a high molecular weight dimethyl terephthalate solid polyester is disclosed in which the polyester is incorporated into a hot melt of an hydroxy-functional linear polyester having an hydroxy number of at least about 20, an acid number of less than about 30 and a molecular weight in the range of 1,000 to 10,000. This forms a molten mixture containing from about 20% to about 55% of terephthalate polyester which is maintained as a hot melt until a sample of the melt forms a clear to slightly cloudy solution in a 50% mixture thereof with 2-ethoxy diethanol glycol acetate. The reacted hot melt is then mixed with an organic solvent to form a solution which is useful in thermosetting solvent solution coating compositions. 
     Aqueous coating compositions may be made using water having dispersed therein a salt of an epoxy phosphate with a volatile base and having stably dispersed therein the aforesaid reacted hot melt after the same is mixed with a water-miscible organic solvent to form a solution which is dispersed in the aqueous medium and cured with a curing agent reactive with hydroxyl functionality.

Abstract: The invention relates to a method and apparatus for treating a moving web prior to the applying of a photosensitive coating liquid. In order to suppress the entrapment of air between the coating layer and the web, the surface of the web is electrostatically charged so that the coating liquid will be attracted to the web. Wide variations of the potential distribution across the web are avoided by subjecting the web to heat while simultaneously bleeding off part of the surface potential. The heating step increases the mobility of electrostatic charge and accelerates the charge redistribution across the web. The web is subsequently cooled to a temperature between 5 and 25°C in order to preserve the surface potential of the web until the web is coated.

Abstract: The invention relates to a modulation method by means of which initially mutually phase-displaced carrier signals fT are generated and subsequently are mixed, separated from one another, with a modulation signal f1. The mixture products are added in order to obtain the modulated carrier signal. In the method according to the invention, three mutually phase-shifted carrier signals are generated, the first carrier signal being phase-shifted by -45 DEG and the third carrier signal being phase shifted by +45 DEG  with respect to the second carrier signal. The modulated carrier signal only contains the 6th harmonic (7fT +/- f1), as a result of which the requirements for the low-pass filter to be connected thereafter are extremely low. The method is particularly suitable for generating MPX signals for stereo broadcasting. <IMAGE>
