Regula 7517. As a part of the system the device is used together with the eddy-current

magnetographing device Regula 7517B and magnetizing equipment Regula 7517C.

The User’s Guide contains information concerning device and its components design,

principles of operation and specications. The Guide also provides instructions on the correct

and safe use of the device (intended use, maintenance, routine repairs, storage and

transportation) and on its technical condition evaluation when deciding whether it is necessary

to send the system for repairs.

Description of the device software is given in a separate document.

Personnel operating the device are required to:

DESCRIPTION AND OPERATION

Device Description and Operation

Device Function

The device is intended for forensic examination of rearms and ammunition serial numbers

with the following purposes:

zserial numbers authenticity verication,

zrecovery of initial numbers in case of any damages in their relief (corrosion, scale, wear, etc.),

zrecovery of initial numbers in case of their removal,

zgeneral trace evidence examinations and non-destructive testing of relief and stresses

in the surface layer of metal objects.

Regula 7517A is a set of hardware and software products enabling visualization (video

imaging) of relief and structural inhomogeneity of metal surface with magnetic properties

(traces of mechanical processing, inclusion of non-ferromagnetic materials, surface aws

of welding seams), without removing the lacquer-and-paint coating (if applicable) by methods

of magneto-optical visualization. A PC is used for capturing, collecting, processing, transferring

and displaying information.

Area of application

The device is intended for use by forensic laboratories, law enforcement agencies, judicial

authorities, customs and insurance companies. Regula 7517A can be used for express

inspection (e.g. at customs or by highway patrol), as well as for advanced forensic examination

of rearms serial numbers in laboratory conditions due to the fact that the device provides

high-quality results, visual evidence and uses non-destructive magneto-optical methods.

In case any changes in serial numbers are detected, further investigations can be carried out

using a special set of peripheral hardware tools (supplied optionally).

Storage and operation conditions

The system is to be used indoors.

CongurationandOperation

Regula 7517A is a set of hardware components and software products. The device allows

examining objects using different methods.

Examination starts with magnetic copying (making a magnetogram = magnetic copy) of

the ferromagnetic object surface. The magnetic copying accessories set (MCAS) contains

various kinds of magnetic scanners which locally magnetize the object, excite its magnetic

stray elds and copy them to the intermediate exible magnetic carrier (magnetic tape) without

removing the lacquer–and-paint coating. The eddy-current scanner (supplied optionally) is

used for investigating internal stresses in ferromagnetic objects and for examining the surface

of aluminum objects.

The magnetogram is loaded into the USB device for magneto-optical visualization

(MOV USB device) where information about object’s surface layer is scanned. The MOV USB

device combines two functional components: optic-mechanical block and block of electronics.

The optic-mechanical block (OMB) contains a magneto-optical visualizer which converts

magnetic stray elds of a magnetic copy into an image and a special tape drive mechanism

which moves the magnetic copy relative to the visualizer.

A magnetic copy is loaded into the tape drive where it is automatically detected and

introduced into the tape drive tract. Then it is scanned step-by-step by a sensor designed

on the basis of a magneto-optical crystal. Magneto-optical visualization of magnetograms of

the examined object is based on Faraday magneto-optical effect which occurs in crystalline

lms of Bi-containing ferrite garnets.

Light distribution obtained as a result of visualization is received by the sensitive element

of the video camera and is converted into a digital TV signal which is further processed and

examined with the help of PC software.

Step-by-step input of images into a PC allows making automatic panoramic stitching of a

digital image from several sub-shots.

The block of electronics manages OMB resources (electric drive, inductor, illuminator,

video camera and indicators).

The PC operates the MOV USB device via special software. The PC displays newly obtained

and stored examination data which are processed, examined and documented.

Peripherals (supplied optionally) extend examination possibilities of the device by applying

additional methods and means of investigation.

The device operates together with the following peripherals:

zUSB device for optical input,

zmagnetic powder visualization device,

zeddy-current probe,

zelectrochemical etching device.

Basic functions of NUCA (EYER) software:

zoperating USB devices,

zinput and processing of images,

zautomatic program correction and panoramic stitching of MOV frames,

zimage scaling and rotation,

zcomparison of images,

zmeasurements of linear and angular sizes,

zsaving and printing of image les as illustrations to the photo charts.

1.1.4

A set of operational documents contains data on design, principles of operation,

properties of the device and its components. It also contains instructions on correct and safe

device operation and evaluation of its technical condition when deciding whether it is necessary

to send it for repairs.

The device is designed as a compact unit for desktop use. The general view of the device

is given in Figure 1.

Means of Measurement, Tools and Accessories

The device belongs to indicating (not measuring) equipment. Therefore control of device

operation is carried out using test-objects, simulating several known methods of number

alteration (cold calking, sealing with fusible metals, dot welding and pressing-in fragments).

See paragraph 2.2.1.2 for the details of the device operational check-up using the test-object.

Test-objectspecications

The test-object (see Figure 2) imitates an examined object. It is a plate (unkilled sheet

steel) with the thickness of 0,8–0,9 mm bearing “291634” original number applied by mechanic

pressing (cold stamping). The original number details: manual stamping with the use of “font

No.6” stamping set and a hammer on a massive anvil. The depth of digit relief is about 0,3–

0,4 mm.

Three digits of the original number were modied: “9” to “0”, “6” to “9” and “4” to “5”.

Thus, the altered number appears as “201935” (altered digits are underlined).

Digit “9” of the original number was altered manually using cold calking of one element

(crosspiece) of digit “9” with the help of bench tools. Then digit “0” was stamped over

the remaining contour of digit “9”.
