Title: Support comb for cable core identification sleeves - has variously sized sleeves held between uniformly spaced tooth pairs on simple or complex combs
Inventor: ANDREAS EGGENBERGER
IPC: H01B13/34
Filed: 1993-03-25
Abstract: The identification device includes transparent thermoplastic sleeves (6,6',6'') which are grooved to fit on ribs (14) moulded on the inner faces of the toothed pairs (5a,5b). Within the identical upper sleeve bodies, suitably marked tags (7), forming alphanumeric identifying codes, are retained by friction. Each lower sleeve body (6b) is dimensioned to suit a particular conductor diameter. A hollow centre is enclosed by the upper body and flexible side walls, linked by a flat base, which deform to retain a conductor when inserted. Toothed pairs are alternatively moulded so that they interlock with minimal clearance to form continuous rows. The device may include simple combs (51) with one row of unpaired, equally spaced double-sided teeth (55), between which similar sleeves are fitted. Alternatively the sleeves, otherwise identical, have the lower body curtailed by half its length, near the comb, which has a transverse stop-bar to limit insertion. ADVANTAGE - One comb can carry varying numbers of different sleeves.

Abstract: The minicamera detects at least one beta and gamma nuclear radiation (or the like) emitted by a radioisotope contained in a body (1, 2). Its imaging head (300) comprises a collimator (301), a scintillator (302) and a photodetector assembly (303 to 309). According to the invention, the imaging head (300) is also provided with a modulation grid (312) having holes, which is arranged between the collimator (301) and the scintillator (302). Under the action of a suitable mechanism (313), the grid can open or close the collimator fully. The signals from the photodetector assembly which are collected in the opening position (or closing position, respectively) are supplied to a first (423) (second - 424, respectively) image memory. Comparison and calculation means (421) provide, by simple subtraction, the desired useful signal on the basis of the contents of the two memories (423, 424). Application: assistance for excision of cancerous tissue.
