Patent EP-0360382-A3 (EP)
Title: Clean release laminate construction with latent image
IPC: B41M5/165
Filed: 1989-07-04
Abstract: The present invention provides a laminate construction including a backing sheet (18), which may be in the form of a continuous web, and a face sheet (12) covering at least a portion of the backing sheet. A releasable adhesive (16) secures a first or lower surface (13) of the face sheet (12) to a first or upper surface (17) of the backing sheet (18) such that the face sheet and backing sheet are readily separable. The releasable adhesive (16) contains therein a first composition (22) which, when subjected to an imaging force, forms a latent image (28, 30) on both of the first surfaces of the face and backing sheets. This latent image may be developed at a later time by contacting the image with a second composition which, when exposed to the first composition, forms a visible image. In the laminate, the face sheet (12) may be imprinted with legible and/or covert information. The covert information may be duplicated on the underside of the face sheet or on one or more intermediate sheets as well as a backing sheet. The face sheet can then be readily peeled from the construction and be used as a label, tag, form, or the like. The underlying sheets retain the same information as the face sheet. The covert or latent information can be developed at a later time to produce a visible image. All elements of the construction have nontacky surfaces, permitting easy handling and storage.
Patent EP-0352082-A3 (EP)
IPC: G06F7/78
Filed: 1989-07-19
Abstract: A memory stack used for storing microinstruction addresses in a pipelined CPU is constructed as a last-in, first-out memory using a stack pointer which applies a read control to one location of the stack and applies a write control to the next higher location. An unconditional read and write is done every machine cycle, before a microinstruction could be decoded, then the data on the read bus, or data from the write bus, is used and the pointer is incremented or decremented if a stack Push or Pop is decoded. These correspond to a Call or Return microinstruction. Thus the delay in decoding the microinstruction does not prevent completion of the stack operation in one machine cycle.

through a nuclear fuel assembly (10), in which a coolant 
flow restrictor (40) having longitudinal ducts (30) is 
provided with plug members (48, 49, 50) of different

Title: Method for testing counters, in particular electricity, water or gas meters, and device for carrying out this method
IPC: G01R35/04
Filed: 1990-01-23
Abstract: The counter has a rotating element with an optical reflectivity which periodically changes along its circumference or a changing optical transparency.

Title: Optical transmitters linearized by means of parametric feedback
IPC: H04B1/62
Filed: 1990-07-07
Abstract: The invention discloses a general technique of taking advantage of the stability of the modulator transfer characteristic in order to correct for second and third order distortion. These objectives are achieved in a way compatible with the nature of the video distribution frequency formats. The method of this invention for linearizing the amplitude transfer characteristic of integrated optic devices for analog transmission is accomplished by injecting pilot signals, monitoring the harmonic and intermodulation distortion content of the optical output, and feeding back bias signals to parametrically tune the operating points of the integrated optic modulator and of a predistortion network. General principles for realizing suitable parametrically tunable predistortion networks are also presented.
