Patent ES-8500848-A1 (ES)
Title: Sealed package for storage of fruit and vegetables
IPC: B65D81/28
Filed: 1983-11-16
Abstract: Package comprises a sealed enclosure for the produce, also containing a sealed packet of dessicant and a carbon dioxide absorbent. The dessicant packet is permeable to water vapour but retains any soln. formed in it. The quantity of dessicant is sufficient to absorb water vapour to prevent mould growth during the intended storage time of the package; the amt. of carbon dioxide absorbent is sufficient to keep the carbon dioxide concn. below an injurious level for a similar period. - Absorption of CO2 causes a drop in pressure in the package, which is made of oxygen-permeable material, so oxygen diffuses in keeping the oxygen concn. in the package above the minimum required to prevent anaerobic respiration by the enclosed produce. - The package retards ripening of fruit and vegetables. It is not necessary to evacuate or otherwise modify the environment in the package when it is filled.  (0/0)
Patent ES-8406633-A1 (ES)
Title: Method of and circuit for analyzing output signals from a sensor installed in an internal combustion engine
IPC: F02D45/00
Filed: 1983-12-02
Abstract: A method for evaluating output signals of a sensor for measuring operational parameters of an internal combustion engine, utilizes characteristic wave forms of signal portions derived from a sensor. Threshold levels for setting the beginning and the end of an injection process are determined from threshold levels of an (n+m)th signal portion which are derived from a fraction of preceding nth signal. The device for carrying out this method includes a store for the peak value of the nth signal and a controlled discharging device which cooperates with a threshold switch and which is controlled by other parameters of the engine such as rotary speed.
Patent ES-8407640-A1 (ES)
Title: Induction heating device for several oscillating charges fed by the same current source inverter.
IPC: H05B6/04
Filed: 1984-01-04
Abstract: Each of the oscillating loads (82, 83) comprises a heating inductor forming part of a parallel-resonant circuit. These loads (82, 83) are connected in series between the output terminals (18, 19) of an inverter (10). They are respectively connected in parallel with electronic power breakers (118, 110) which, through variations in the respective on/off duty cycles for these loads (82, 83), permit substantially independent regulation of the power supplied by the inverter (10) to each of the loads (82, 83). In induction forge furnaces (for slugs or billets) the invention permits the heating power to be regulated as a function of the speed of advance or of the output temperature of the parts. In furnaces for wires or for cables, it furthermore permits compensation for the "dead ends" when starting or restarting the installation after a stoppage.

Patent ES-8900119-A1 (ES)
Title: Cable television system selectively distributing pre-recorded video and audio messages
IPC: H04N7/173
Filed: 1987-01-16
Abstract: A method of, and a system for, selectively delivering still television video with accompanying audio to home subscribers over a cable television system for advertising, promotional or educational purposes. A maximum number of home subscribers can interactively request presentations of their own choosing to be displayed on their home television sets. Only one standard television channel is required for transmission of still video with accompanying audio to serve 300 concurrent users. No equipment is required in the subscriber's home. The video is presented as still frames from one of a number of videodisc players, transmitted over one television channel during the appropriate time interval of 1/30th (or 1/25th) of a second. Such video frames, which may also contain overlaid graphics information, are uniquely addressed to a remote storage device. Unused bandwidth is used for the transmission of up to 300 discrete audio messages. The remote storage device identifies the appropriate video still frame, stores it, combines it with the corresponding audio message and conveys both to the home subscribers' television on a pre-selected channel. By uniquely addressing video frames to the remote storage device, either 30 (or 25) different video frames per second can be conveyed on one television channel to 30 (or 25) different remote storage devices for retransmission to home subscribers. Thus, if a home subscriber sees a given still video frame for 10 seconds, his remote storage device need not be updated for those 10 seconds, enabling the system to transmit 300 (10 secondsx30/second) different video frames to 300 other remote storage devices, thereby serving 300 concurrent users.

Title: Vehicle systems for use in cosmetic compositions
Inventor: NORTON MICHAEL JAMES
IPC: A61K8/00
Filed: 1990-08-03
Abstract: Disclosed is a unique vehicle system which provides a desirable rheology to products formulated therewith, enhanced dispersion of actives therein, and improved deposition of actives therefrom. This vehicle system comprises a primary thickening agent which is a nonionic long-chain alkylated water-soluble polymer, and a secondary thickening agent which is a water-soluble polymer having a molecular weight greater than about 20,000, preferably a natural polysaccharide, dispersed in a compatible solvent. Optionally, a rheological aid, which is a chelating agent, may be included in the vehicle system. Also, optionally, a distributing aid, which is a water-soluble polymer of either high molecular weight or strong ionic character may be included in the vehicle system. These vehicle systems are useful in cosmetic compositions which are used to deliver an active component to the skin or hair. The vehicle systems are particularly useful in hair care compositions, especially rinse-off hair conditioning compositions, because they effectively deliver the hair conditioning component to the hair without depositing a substantial amount of the vehicle material onto the hair.
