Title: Removal of nitrosamines from beverages
IPC: C12H1/16
Filed: 1980-03-18
Abstract: A process for reducing the nitrosamine content of a beverage comprises submitting the beverage after it has been prepared but prior to its final packaging for sale to illumination with visible light and subsequently storing the beverage in the dark at between -5 and 30 DEG C. The process of the invention does not normally adversely effect the flavour of the beverage. The beverage may be whisky or another alcoholic beverage. The beverage may flow by convection from the lower part of a vat (2) past the source (4) of the light and then be returned to the vat at the upper part thereof. Alternatively, the vat may be provided internally with a light source surrounded by an annular space through which the liquid flows upwardly. The beverage may be heated whilst in the vicinity of the light, and may be treated with an adsorbent to remove sulphydryl compounds. <IMAGE>

Title: A mechanism with helicoidal planes for increasing the power of a driving shaft
IPC: F01B3/00
Filed: 1980-05-07
Abstract: The mechanism with helicoidal inclined planes according to the present invention is particularly adapted for increasing the power of the driving shaft of a motor e.g. an internal or external combustion motor or an electric motor. For this purpose said mechanism exploits a rotary-translation motion of masses (M1, M2) in an unstable equilibrium, the rotary motion thereof around the translation axis taking place along helicoidal planes with different inclinations. Shaft (4) is caused to turn through 180 DEG  as a result of rollers (15) carried by an integral member (11) rolling up a helicoidal plane (AC) inside a cylinder (2), after which a roller (16) on cylinder (2) engages a helicoidal plane (A2 C2) on member (11) for rotation through a further 50 DEG . For the next 180 DEG , the rollers (15) roll down a helicoidal plane (DG) inside cylinder (2). The differences in inclination of the helicoidal planes result in a positive torque difference being generated which is transmitted to the driving shaft (4), the masses (M1, M2) mounted on the shaft (4) acting as flywheels. <IMAGE>

Title: Pressure relieving devices
IPC: F16K17/14
Filed: 1981-06-09
Abstract: A pressure relieving device comprising a round flexible plate 4 bent downward and having its periphery welded to the inner surface of a cylindrical hatch coaming 3 at appropriate intervals, a sealant 11 for sealing the gap between the remaining part of the plate periphery and the coaming inner surface, a reinforcing rigid plate 5 provided on the flexible plate 4, a beam 7 extending across the coaming 3 under the flexible plate 4, and a rupture bar 6 connecting the flexible plate 4 through the reinforcing plate 5 to the beam 7. If an abnormally high pressure acts on the flexible plate 4, the rupture bar 6 breaks and the flexible plate bends upward. With the upward bending of the plate 4, the welds 10 between the plate 4 and the coaming 3 are deformed and broken, allowing the plate 4 to be blown off from the coaming. Thus the device, if installed on a fuel tank, serves to relieve the pressure in the tank for the maintenance of safety. <IMAGE>

Abstract: The invention discloses pruning apparatus of the compound action hook and blade type. At the upper end of a longitudinally-extending handle, a stationary hook is fixed and extends upwardly therefrom in a plane parallel to and offset from the longitudinally-extending plane of the handle. It defines a downwardly-facing arcuately-shaped limb-engaging-surface for engagement with a limb. There is a movable blade which has a cutting edge and is operable to be reciprocated in an intersecting manner through cutting and return strokes with relation to the engaged limb and to the limb engaging surface of the fixed hook. A lever is pivotally mounted relative to the hook and a link pivotally interconnects to each of the lever and movable blade. The hook and movable blade and lever and link are each disposed contiguous to a common vertical plane. A rope and pulley assembly operatively interconnects with the movable blade through the lever and link and has a free end extended to the lower extremity of the handle for effecting pivotal movement of the movable blade through the cutting stroke responsively to a manually effected pull. Spring means effects movements of the movable blade through a return stroke. An adjustable grip in the form of a manually engageable member has a sinuous opening therethrough for the extension of the rope thereinto and therethrough and therefrom in the slip free positioning and grasping of the grip relative to the rope for the facilitating of the application of a force on and substantially parallel to the rope.
