Title: Security device for a safe-box
IPC: E05G1/06
Filed: 1984-03-27
Abstract: The present invention relates to a security device for safe-boxes, especially with a sliding device, more especially designed for a series of juxtaposed and superimposed safe-boxes. The object of the device is to house, in a sealed corridor 1, a half-depth door 4 which opens outwards, behind which there is a sliding safe-box fitted with a handle which the individual concerned grips in order to draw the safe-box to him. A limit stop 6 stops the safe-box at the end of travel and constitutes an obstacle in the event of an attempt to break in through the door 4. The longitudinal part of the corridor 11 is deep enough for the break-in attempt only to be able to take place at arm's length (reduction in movement, impossibility of leverage). Use: safe-boxes rented out by banks, individual safe-boxes and cashboxes.

A ring-shaped groove (8) in the top of the bit accommodates two concentric tubes or pipes (2,3). The inner pipe (3) has an ID only slightly greater than that of the bore (5) through the bit. There is a flap valve (18) hinged on a pivot (17) in an opening in the side of the pipe, to assist in moving earth upwards. The top of the pipe is screwed to a sleeve (11) with an inward directed flange (13). It may be driven downward by a hammer or ram head (1). This has a groove in the end (9) engaging the outer pipe (2).

Title: Tool for cutting small-diameter tubes from the inside without deformation
IPC: G21C3/334
Filed: 1985-12-23
Abstract: The invention relates to a flexible tool for cutting small-diameter tubes from the inside, using the electric arc-saw technique, and which can be applied in particular to the tubes of steam generators GV of nuclear power stations. This tool, installed on a remote manipulator, comprises: - a flexible, rigid, fixed metal rod 901 carrying the electrode disc 902, extended by a conducting braid 903; - a rigid insulating tube 904 centred in the tube, trapping the end of the fixed rod, given a rapid rotational movement and endowed with an axial travel Z relative to the rod; and extended by a flexible hose 905. The rotational speed and the axial travel correspond to the displacement and to the eccentricity of the electrode on the component to be cut; - a water supply coming to submerge or sprinkle the electrode disc by means of a sliding-turning connection 906. This connection relieves the mobile tube 904 of the weight and of the parasitic forces of the supply cable 907.
