Patent FR-2343655-A1 (FR)
IPC: B65D21/00
Filed: 1977-03-07
Abstract: In the provision of containers, only part of the production process for which can take place at the site of use, there is, on the one hand, the problem of transporting an at least substantially preshaped container preform in as space-saving a manner as possible from the production site to the site of use and, if possible, storing it there in a space-saving manner as well, and, on the other hand, of shaping the container preform to the final shape with the minimum effort at the site of use. According to the proposed solution, a container preform (1) with a slightly conical shell (3) for stacking purposes, a fully finished opening rim (2) and a fully finished bottom (6) is produced at the production site, the shell being provided with a stacking bead (9.1-9.5) which prevents oversnug fitting of stacked preforms into one another and being stacked ready for shipping and further processing. At the site of use, preforms prepared in this way are withdrawn from the transport stacks and the shell (3) above the bottom (6) is converted to an at least approximately cylindrical shape by expanding it, preferably in sections, to give containers with an optimum volume in relation to the transportation base area subjected to stress in the filled condition.

Title: Parameters recording system defining vehicle movement - utilises one channel on which differences from previous recorded value are made
IPC: G07C5/08
Filed: 1977-03-30
Abstract: Movement of a vehicle on tracks is determined by recording various parameters defining the movement such as actual speed and time and any signalling events. Logic signals permit recording of the parameters on the same channel. An analogue signal representing speed is compared with voltage from digital to analogue convertor which receives its input from a counter to which the comparator output passes. At balance counter output oscillates between values above and below the speed. Speed difference from last recording is determined by counters to which speed tolerance values are applied. A circuit memorises values which exceed tolerances and starts the recording.
