Influence of the anterior and middle cranial fossae on brain kinematics during sagittal plane head rotation

Abstract: A 2D physical model of the human head was used to investigate how the irregular skull base structure affects brain kinematics during sagittal plane head dynamics. The model consisted of a rigid skull vessel with interchangeable skull base structures. One version of the model used a skull base mimicking the irregular geometry of the human. A second version used a skull base structure approximating the anterior and middle fossae as a flat surface. Silicone gel simulated the brain and was separated from the vessel by a paraffin layer which provided a slip condition at the interface between the gel and vessel. The model was exposed to 7600 rad/s2 peak rotational acceleration with 6 ms pulse duration and 5° forced rotation. After 90° free rotation, the model was decelerated during 30 ms. Five repeated tests were conducted with each version. Rigid body displacement, shear strain and principal strains were determined from high-speed video recorded trajectories of grid markers located at different positions in th...

Computation of parts requirements for production scheduling

Abstract: The computation of parts requirements or the timing of these requirements constitute important parts of the data processing in connection with production control. This kind of data processing is much more complicated than the simple updating of files. It is therefore often regarded as a problem for which random access memories are necessary. It is shown in this paper, however, that simple serial-access memories such as magnetic tapes, when used together with a fair amount of ferrite-core storage, constitute a most efficient tool for the kind of data-handling involved. The main theme of the paper, however, is to show how matrix algebra can be used as a very convenient tool for treating problems in production control both for theoretical discussions and practical data processing. In order to make the paper readable also for people who are not familiar with matrices, this concept is introduced on the basis of simple elements of the problem of computation of parts requirements. Different machine procedures for the matrix handling are discussed.

A vehicle radiator grille, a headlight housing and a method of mounting the grille onto a vehicle

Abstract: A method of mounting a grille (30) between a pair of spaced headlight housings (15) on a vehicle (11). The grille (30) is fixed directly onto mounting points (24, 25) formed on the headlight housings (15). The grille (30) has upper and lower attachment means (34, 35) at each end that co-operate with attachment means on the headlight housings (15).

Spring clamp to connect injection nozzle to injection line

Abstract: The spring clamp (10) has a U-shaped main body with a web (20) and two projecting legs (22). A circular segment (38) extends outward at an angle from one longitudinal edge of each leg. A spring bracket (40) extends from the centre of a longitudinal edge of the web towards the connection socket on the clamp. Due to its axial dimension, the bracket engages on a flat surface (48) of the outside of the injection line (14) when fitted. The free end of the bracket is V-shaped. The bracket is formed in one piece with the web.
