Title: Treating drinks esp. wine to eliminate tartar - by supersaturating with dissolved tartar cooling and sepg.
IPC: C12G1/12
Filed: 1977-05-27
Abstract: Tartar is eliminated from wine, sparkling wine and other drinks contg. tartaric acid by (a) supersaturating the drink with dissolved tartar, (b) cooling to a temp. between below the storage temp. and the lowest probable transport temp., then (c) sepg. the crystallised tartar. Process is effected in an appts. comprising a conduit from the drinks storage to an entry point for the dissolved tartar, followed by means of cooling and sepn. The cooling may also be carried out in a separable vessel in a discontinuous process. Process avoids future pptn. of tartar from the drinks. It is simple and quick and may be carried out continuously or discontinuously.

Title: Glove box
IPC: G21F7/015
Filed: 1977-06-28
Abstract: A glove chamber in which oxides of nitrogen are formed, e.g. during soln. of radioactive materials in nitric acid, incorporates an appts. for converting such gases into prods. which can be discharged safely into the evacuation system of the installation, or condensed.

The appts. allows noxious nitro-gases to be destroyed, while occupying little space and excluding all radioactive contamination, or any decontamination difficulty.
Patent ES-466446-A1 (ES)
Title: Multiple reflection suppression in marine seismic exploration with long source and detector arrays
IPC: G01V1/38
Filed: 1978-01-28
Abstract: In marine seismic exploration, a long array of sources efficiently transfers energy along the reflection path. Multiple reflection rejection is achieved by normal move-out discrimination at selected trace distances for each reflection. The length of the source array is changed in accordance with the geological characteristics of the sub-surface formations being explored and the reflection time of reflections from formations of interest. A split source array allows one section of the array to be moved with respect to the other to change the overall length of the array without changing the number of sources which are fired. Primary to multiple reflection enhancement is obtained by selecting only traces having source to detector offset distances with a primary to multiple amplitude response ratio greater than one.

Title: Wind sifter.
IPC: B07B7/083
Filed: 1979-04-20
Abstract: The invention relates to an air separator having a rotor provided with feed passages for the material to be separated which extend radially outward and between which extraction openings are arranged. The space between adjacent feed passages which exists between the outer end of the feed passages and the extraction openings is axially delimited on at least one side by a stationary element forming part of an extraction housing. In this way, problems of wear in the outer region of the rotor are reduced. In addition, there is no longer any need for an exact sealing gap to be maintained between the rotor and the extraction housing. Finally, the free flow cross-section for the separation air is increased for the same overall dimensions of the separator.

Title: Vibratory feeder leaf spring arrangement
IPC: F16F15/06
Filed: 1979-05-29
Abstract: A vibratory feeder has an elongated base assembly that is supported on a foundation by longitudinally spaced vibration isolators. Projecting upwardly from the base assembly at longitudinally spaced locations are a plurality of leaf springs with upper portions that support a trough assembly. The base and trough assemblies have masses, with the centers of these masses being spaced apart along an upwardly extending axis. The trough assembly is driven transversely of the upwardly extending axis by a driver. The assembly masses create inertia forces acting at the mass centers, and these forces form a force couple urging a rotational motion on the feeder as a whole. The leaf springs are arranged to deflect along non-parallel paths to guide the trough assembly in both curvilinear translation and rotation with respect to the base. This rotation opposes the rotational urge created by the inertia force couple to thereby eliminate rotational motion of the trough with respect to the foundation, so that the trough moves only in curvilinear translation with respect to the foundation.

Patent ES-8100206-A1 (ES)
Title: Dip tube and valve with quick-disconnect coupling for a collapsible container
IPC: B65D77/06
Filed: 1980-01-14
Abstract: The present invention is directed to a dip tube and valve with a quick-disconnect coupling for use in combination with a collapsible bag to dispense a liquid product therefrom. The dip tube is extruded or otherwise formed from plastic or other suitable materials and includes at least one channel in the peripheral surface thereof extending along the entire length of the dip tube. As a vacuum or suction is applied to the dip tube by a pump, initially all of the air within the collapsible bag is extracted therefrom. Subsequently, the liquid product is dispensed out of the collapsible bag and the bag collapses around a portion of the dip tube which is no longer surrounded by the liquid product. Progressively, as the liquid product is removed, the bag will continue to collapse around the dip tube, and the liquid product will continue to flow through the longitudinal channel of the tube until the contents of the collapsible bag are exhausted. The collapsible bag has a fitment or spout to which a valve with a quick-disconnect coupling is connected. The dip tube may be mounted in either the bag fitment or the valve. The quick-disconnect coupling of the valve is adapted to receive a mating coupling from the hose socket of a dispensing hose. When the respective couplings are engaged the valve is biased in an open position. The valve is normally biased to a closed position when the couplings are not engaged.

Title: Hydrostatic transmission control system
IPC: G05D3/14
Filed: 1980-07-24
Abstract: The hydrostatic transmission control system includes a first and second two-position solenoid valve which function to alter the hydraulic fluid parameters as delivered to the servo control cylinders of a variable displacement pump associated with a hydrostatic transmission.
