Title: Window/door ventilators of modular construction
Inventor: GIBSON COLIN FREDERICK
IPC: F24F7/00
Filed: 1990-12-01
Abstract: A window/door ventilator is of modular construction such that by appropriate selection of parts the ventilator can be adapted to suit different window/door configurations. In the illustrated construction, an exterior element (19) is directly connectable to different forms of interior element eg (17) or (21), to form the ventilator, each element having a ventilation aperture therethrough (not shown), and the ventilator having a channel at its lower edge to receive glazing and being configured at its top edge for receipt of, or fixing to, the window/door frame. The exterior element (19) is of insulating plastics material and the interior element of extruded aluminium. In alternative constructions extruded aluminium interior and exterior elements are interconnected by separate connection elements of plastics which provide a thermal break. A pivoted closure member for controlling air flow through the ventilation apertures may be provided, and a canopy and grille assembly may be fitted to the exterior element. <IMAGE>

Title: A shock absorber
Inventor: TUSCH KLAUS NORBERT
IPC: F16F9/14
Filed: 1993-01-19
Abstract: A shock absorber 1 comprises a hollow body 2 packed with a flowable material such as silicone putty in two compartments 3 which define a 340 DEG  segment and which are partitioned in the body 2 by a vane 4. There are holes 6 through the vane to provide a passage between the compartments. The body 2 is fixed, and the vane 4 is rotatable, being mounted on a rotatable shaft 5. As the shaft rotates, the vane 4 sweeps out the volume of the hollow body. Under slow applied loads the silicone putty is flowable, and passes through the holes 6 so enabling the vane 4 to move. However, rapid shock loads applied to the vane cause the silicone putty to become relatively rigid, the vane thus will not turn and the shock is absorbed by the putty. The shock absorber may be used as a hinge in a bridge structure. <IMAGE>

Title: The use of, and a process for the synthesis of, a superstoichiometric MgAl2O4 spinel
Inventor: ZYL ARNOLD VAN
IPC: C01F7/162
Filed: 1994-02-14
Abstract: The invention relates to a superstoichiometric MgAl2O4 spinel, to a process for the synthesis thereof and to the use of the spinel. To synthesize this spinel, which can be used, in particular, as material for a high-temperature crucible, a precursor mixture comprising intimately mixed oxides of the corresponding metals in the spinel is produced, the magnesium being added in a superstoichiometric amount to the precursor mixture. Prior to spine formation, from one to five per cent by weight of a reactive salt containing fluorine and/or boron, based on the metal oxides of the spinel, are added to the precursor mixture and the precursor mixture doped in such a way is mixed for from 0.5 to 3 hours. Finally, to synthesize the Mg(1+x)Al2O4 spinel which is superstoichiometric in respect of magnesium, the mixed precursor mixture is heated for between 0.5 and 4 hours at a temperature between 1150 DEG C and 1400 DEG C.
