Abstract: PORTABLE CONTAINER FOR VALUABLE ARTICLES            Abstract of the Disclosure A portable depository container 10 for an automated teller machine (ATM) articles as, for example, magnetic credit cards captured by the ATM.  With the container dismounted from the ATM, an entry slot 16 is locked against passage of articles therethrough by means of a bar 22.  Upon the container being mounted in a receiving cradle 18 of the ATM, the bar 22 is moved to an unlocked position by means of key pins 168, 170 which engage and move rearwardly with a pair of slide members 42, 44.  This movement of the member 42 brings about a rotational movement of a resettable indicator wheel 76 which carries a series of markings on its perimeter. The particular marking of the wheel 76 visible through an indicator window provides an indication of the number of times the bar 22 has been unlocked since resetting of the wheel, and can thereby indicate whether tampering with the container has taken place.  A second embodiment for handling articles such as currency in envelopes utilizes a resettable indicator slide 208.

Abstract: The cable C to be stripped is wound with non-touching coils and crossed layers of cable onto a drum 6 having a perforated core 10 rotatively mounted in a thermally insulated container 1. By injecting into the container liquid nitrogen under the control of a temperature sensor and by circulating the gases contained in the container through the core of the drum and the cable coils, the whole of the cable is cooled down to a temperature at which the plastics coating and, as the case may be, the outer steel sheath of the cable become brittle. The cable is then unwound and, when it has left the container, it is subjected to various mechanical stresses. The stripped cable is finally wound onto a take-up reel 3.

Abstract: TUBULAR CONNECTION      ABSTRACT      An improved pin member adapted for use in a tubular connection where  said pin member  is  adapted  for coaxial threaded engagement with a box member having a counterbore for receiving the pin member.  A pilot surface is disposed from a distal-proximate end to the distal end of the pin member inclining to a lesser extent than the angle of the incline of an internal sealing surface of the pin member.          The pilot surface is substantially parallel to the axis of the connection.  This pilot  surface allows the end-of-pin flat thickness to be increased thereby allowing positioning of the interengaged threads so as to provide an increased annulus thickness of the box member thereby increasing the axial tensile strength capability and burst pressure rating of  said  tubular  connection while  additionally protecting said internal surface of said pin member and providing a rugged end-of-pin flat.   Additionally,  a pilot surface is presented for the free end of a box member so as to provide additional protection of the external sealing surface of the box member and providing a more rugged end-of-box flat.

Abstract: ABSTRACT   A system for mixing and refining pulp in which the raw material is conveyed into a cylindrical drum (10) and propelled therethrough in linear/ spiral direction by a co-axial rotor (26) comprising a plurality of mixing/ refining elements (40). The raw material is mixed and refined during the relative rotation between the rotor (26) and the drum (10) in a plurality of co-axially extending grinding areas (30) defined between rotatable grinding elements (40) on the rotor (26) and a facing grinding surface (28) on the interior of the drum while being simultaneously compressed therein and alternately decompressed in areas between the grinding areas (30). The rotatable elements (40) are adjustably mounted to the rotor (26) so as to vary the spacing between the grinding surface (28) on the interior of the drum and a rotatable grinding surface (42) on the grinding elements (40), while simultaneously adjusting the material feeding angle of the grinding areas (30). The adjustment can be achieved mechanically or by a hydraulic system during the operation of the apparatus to control and vary the flow of the pulp material as it passes through the grinding areas (30) to in-sure optimum and even mixing and refining of the pulp.
