Title: Edge gluing machine veneer or plastic strip trimming - involves scanner, and single saw cutting front and rear in two movements
IPC: B27D5/00
Filed: 1979-07-16
Abstract: Protruding solid strips of wood veneer or plastics, which are to be cut away, are fitted onto a workpiece with the aid of suitable adhesives in an edge-gluing machine. As the workpiece is being thrust into the trimming station, its front and rear ends are scanned by sensors, so that a trimming device first cuts off the leading edge strip in an upward vertical movement, and then the rear one in a downward vertical movement, using only one sawblade. Use can be made of roller valves for control, and workpiece position-setting valves, and stops. Automatic individual adaptation to workpiece shape is provided, using a single saw assembly.

The first system supports the second which consists of three inclined rod springs spaced about the rotation axis at the same angular separation as the first system rod springs. The directions of the rod springs (5) of the second system intersect those of the first system on the rotation axis. The oscillations of the rotary bearing are sensed and converted into an electronic measurement signal.

External network and PABX numbers are stored together. The first part of the address code, for accessing the store, contains an indication code signifying the direction, i.e. internal or external, and method of forward transmission for the number to be output immediately from the store (CSP). The indication code is in hexadecimal format. Telephones (Tln) are connected via peripheral circuitry (TS) to the switch block (KF). The external junction circuits (OVSt,QUe,NAL) are also connected via peripheral circuitry (AUe,Ue) to the switch block (KF). All peripherals and the switch block are connected for two way transmission to the common control (ZVE) containing the number store (CSP).

Title: Irradiated fuel transport container with lifting trunnions - designed as buffers to crush on impact and protect container
IPC: G21F5/14
Filed: 1980-04-23
Abstract: A transportation and/or storage vessel for irradiated nuclear fuel elements and similar radioactive materials is of cast iron, esp. S.G. cast iron or cast steel and has a lid and lifting trunnions at the top and/or bottom rim. These trunnions are designed as buffers to accept shocks in collisions or if the vessel is dropped. Pref. the trunnions are partly hollow and comprise a cylindrical handling portion, integrally formed mounting flange and thrust region, the flange and thrust region being mounted in the associated seating in the vessel wall; the hollow region provides sufficient deformation capability for the trunnion to act as a buffer. The region at the base of the flange may be designed as an intentional point of weakness to rupture in case of impact. In addn., there may be a further point of weakness in the support region. Shocks or collisions which strike the trunnion region break the trunnion or deform it rather than damaging the vessel.
