Abstract

A laminated product having a thickness that can be adjusted by chipping, and including alternating sheets and layers of an adhesive material in a stack, each sheet possessing an intrinsic resistance to tearing and each layer of adhesive material connecting adjacent sheets in the stack with a linking force which is weaker than the resistance of the sheets to tearing, enabling each sheet to be detached from the stack without tearing. The product includes a housing which is disposed inside the thickness of the stack, and an electronic identification element which is disposed in the housing.

Claims

1. A laminated adjustment shim for compensation of play in a mechanical assembly, the shim having a thickness adjustable by exfoliation and including:

a stack of alternating sheets and layers of an adhesive material, each sheet having resistance to tearing, and each layer of adhesive material connecting two adjacent sheets of the stack to one another by a bonding force which is less than the resistance of the sheets to tearing, so that each sheet can be detached from the stack without being torn;

a blind housing located within the thickness of the stack, the housing having an opening at a surface of the shim; and

an electronic identification component located in the housing.

2. The shim according to claim 1, wherein the electronic identification component includes

a memory having identification information stored thereon for identifying the shim, and

a transmission device that can be remotely queried to transmit the identification information stored in the memory.

3. The shim according to claim 2, wherein the identification information stored in the memory includes at least a serial number of the shim.

4. The shim according to claim 2, wherein the identification information stored in the memory includes at least one of:

identification of manufacturer of the shim, reference of an order for the shim, identification of client, identification of material constituting the shim, reference of a standard applicable to manufacturing of the shim, reference of technical specifications of the shim, reference of certificate of compliance with the standard, manufacturing date, reference of a delivery voucher of the shim, or delivery date of the shim.

5. The shim according to claim 1, wherein the blind housing is defined by an interior wall of the stack, and including a filling material in the blind housing, embedding the electronic component and bonding the electronic component to the interior wall.

6. The shim according to claim 5, wherein the filling material is selected from the group consisting of an epoxy resin, a phenolic resin, a vinyl ester resin, and a polyvinyl resin.

7. The shim according to claim 1, wherein the sheets consist of a metallic or composite material.

8. The shim according to claim 1, wherein the sheets extend parallel to a plane of reference, and the blind housing extends parallel to the plane of reference.

9. The shim according to claim 2, wherein the memory has storage capacity for storing a first portion of the identification information, and

a second portion of the identification information being stored on an external support.

10. The shim according to claim 9, wherein the electronic identification component has a thickness less than 200 μ

m.

11. The shim according to claim 9, wherein the electronic identification component has a cross sectional area less than 2.5 mm².

12. The shim according to claim 9, wherein the electronic component has a read-only mode.

13. The shim according to claim 4, wherein a portion of the identification information is stored in the memory in coded form.

14. The shim according to claim 4, wherein the transmission device received the identification information remotely and wrote the identification information in the memory.

15. Theme shim according to claim 14, wherein the electronic component can be locked in terms of writing.

16. Theme shim according to claim 4, wherein the electronic component has a cylindrical shape with an exterior diameter of less than 4 mm.

17. The shim according to claim 4, wherein the electronic component includes means for measurement of at least one of temperature, pressure, vibrations, and irradiation, and the transmission device transmits measurements made by the means for measurement.

18. A laminated adjustment shim comprising:

a stack of alternating sheets and layers of an adhesive material, wherein

the sheets extend in a first direction, and

the stack extends in a perpendicular to the first direction that defines a thickness of the stack;

a blind housing within the thickness of the stack and extending in the first direction, the blind housing comprising an opening at a surface of the shim;

an electronic component within the blind housing and comprising

a memory having identification information of the shim,

a transmission device coupled to the memory that can be remotely queried to transmit the identification information stored in the memory, and

an antenna coupled to the transmission device and located proximate the opening at the surface of the shim;

wherein the memory and the transmission device are arranged inside a sealed cylindrical glass envelope.

19. The shim according to claim 18, wherein the memory stores the identification information including at least one of identification of manufacturer of the shim, reference of an order for the shim, identification of client, identification of material constituting the shim, reference of a standard applicable to manufacturing of the shim, reference of technical specifications of the shim, reference of certificate of compliance with the standard, manufacturing date of the shim, reference of a delivery voucher of the shim, or delivery date of the shim.
