Title: Container for large parachute - has two compartments for main parachute canopy separable by extractor parachute
IPC: B64D17/52
Filed: 1972-12-27
Abstract: The container is rectangular, and divided into two interconnecting compartments each containing part of the main canopy.

Title: Viscometer for continuously flowing liqs - has a sinker descending through the liq and being timed by two sensors
IPC: G01N11/12
Filed: 1974-10-08
Abstract: A viscometer measures the viscosity of a sample of fluid held stationary in a vertical tube, after a periodic extn. from a continuous flow in a pipe, the measurement being effected by determining the time taken for a solid sinker to descend over a fixed path in the sample tube, and the sinker being returned to its starting point by an upward flow of fluid through the tube. The sinker is shaped to pass through fluid in the tube with streamline flow, creating no turbulence, and the time for sinker descent is checked automatically by two sensors, one at each end of the fixed path. The sample tube is pref. cylindrical and the cross-section of the sinker is pref. circular with a dia. slightly less than the internal dia. of the tube. The buoyancy of the sinker is chosen to obtn. streamline flow and may be adjusted by using materials of different densities and/or hollowing out the body of the sinker. The device is esp. used for continuously flowing liqs.

Title: Volumetric proportioning appts. for paint preparation - uses curved pallet on vertically adjustable rod with graduated scale
IPC: G01F23/04
Filed: 1974-12-26
Abstract: The apparatus for volumetric proportioning of liquids especially with a view to mixing them, involves bringing the level of the liquid into contact with the base of a pallet (4) carried by a rod (3) and whose height may be adjusted. The lower edge of the pallet (4) is very slightly curved and turned towards the liquid while the complete lower end of the pallet is inclined at an angle of about 45 deg. to the vertical. The pallet is manually controlled by a device linked to a counting scale. This visible scale allows the up or down adjustment of the pallet to determine corresponding volumes of the liquids in contact with the base of the pallet.

Title: I-shaped construction game block - all dimensions are multiples of a basic dimension
IPC: A63H33/06
Filed: 1975-01-07
Abstract: The construction game is made in synthetic material with suitably sized pieces for out-door usage. The pieces may be put together to form different structures where each element, though easily detachable, is able to take quite big loads. Apart from these, other requirements have to be fulfilled. The game must excite the children's imagination, give plenty freedom of choice but still the system must be easy to understand and the weight kept reasonably low. The block suggested is I-shaped with all dimensions a multiple of a basic dimension which is, preferably the flange or web width.
