Title: Zpusob kalcinace hydroxidu hliniteho
Inventor: TELJATNIKOV GARRIJ V
IPC: C01F7/44
Filed: 1984-05-18
Abstract: D.c. is passed from source (1) to d.c.-a.c. converter (3), passing a stabilised measuring current through terminals (4,5) to earthing element (6) and current electrode (7). Simultaneously the a.c. voltage from converter(3) passes to commutating filter (11) and sync. rectifier (12). Shaper (16) produces cut-off pulses, controlling the operation of electronic cut-off switch (8) and electronic switch (10). A mixt. of the active signal, noise voltage and internal tuning pulses passes from potential electrode (19) and element (6) to terminals (17, 18). - Switch (8) cuts off the tuning pulses with part of the active signal and noise and is then opened, passing the remaining part of the active signal and noise to filter (9). The mixt. is then passed through switch (10) to filter (11), where the active signal is accumulated and L.F. noise is suppressed. Rectifier (12) passes the rectified active signal and combined conversion freq. to rapid-action filter (13) and the active signal is passed through amplifier (14) to measuring instrument (15).

Patent ES-346952-A1 (ES)
Title: Conveyance of material requiring hygienic disposal
IPC: E04F17/10
Filed: 1967-11-09
Abstract: An apparatus for collecting and conveying material such as garbage or soiled linen, comprises upright shoots 2, each having material entry doors 3, and a valve 4 normally closed to support the material in the shoot and openable to allow the material to pass into a suction duct 1 through which it is conveyed to a separation chamber 5. In a system for garbage, shown in Fig. 1, three air extraction pumps 12 are pneumatically coupled to the duct 1 through a fine filter chamber 11 and the separator chamber 5 which incorporates a coarse filter adjacent its upper end. A valve 4A at the upstream end of the duct 1 normally restricts the airflow into the duct such that a vacuum is maintained, but is opened prior to the opening of a valve 4, such that a high velocity air stream awaits the garbage and causes a high vacuum in the open shoot 2. The valve 4 is pivotally mounted and power operated to pneumatically seal off the duct 1 in its closed position and to locally admit air into the shoot and be scraped clean as it moves into its open position. In the embodiment of Figs. 7 and 7A (not shown), the valve plate rebounds in its open position to shake itself clean. The separator 5 comprises an inlet from the duct 1, below the coarse filter screen and an outlet for air above the screen, valves being provided at 8 and 9 so that the separator may be by-passed by the air. The by-pass is brought into operation when the separator is to be emptied by screw or scraper devices feeding an incinerator 6 on a container. Pressurized air is supplied via line 12D to the top of the separator during emptying, to clear the coarse filter. The fine filter chamber 11 includes a vibrating cloth screen through which air is drawn and from which dust is shaken on to an emptying valve in the chamber base. An interlocking system normally prevents the doors in the shoots from being opened when the shoot valve is open, but a pivoting hopper door, Fig. 16 (not shown) permits the entry of garbage into the shoot at any time. A spur 1c from the suction duct 1 may be provided to supply a system of vacuum points lE for domestic appliances. In a system for soiled bagged linen, Fig. 2 (not shown), the separator comprises a chamber into which the bags fall and from which the air is extracted, an airlock being provided to facilitate removal of the bags. Inwardly opening doors at the top of each shoot and restricted by-passes around the shoot valves facilitate a continuous reduced pressure in the system. Water injection may be provided for the system to prevent frictional electrostatic changing and abrasion of the bags. Each valve may be operated through a photo-electric device sensing the accumulation on top of the valve. In the embodiment of Fig. 3 (not shown), a garbage and soiled linen system are arranged in parallel to be coupled to a common suction source.

Title: Pocket umbrella frame
IPC: A45B19/04
Filed: 1968-04-04
Abstract: In a telescopic pocket umbrella, a carrying loop is attached by its ends to the handle adjacent to the periphery thereof, the loop being secured by terminal pieces on its end which seat against internal shoulders in axial slots 8 in the opposite sides of a flange 7 on the handle end piece 1. The handle consists of a plastic end piece 1 on which is mounted a plastic or metal cylinder 2. The lower end of the stick 3 is secured in the end piece 1 by a transverse pin 5 passing through a drilling in the stick, the pin being pulled firmly into a groove 5a in the end piece by tightening an internally threaded nut 4 with a washer 6. The unlocking rod 13 for releasing the lock between the telescopic stick parts (not shown) is operated by a plastic push button 14, having a shaft 15 which is a sliding fit in a bore in the nut 4 and has an axial drilling which is a force fit on to the end of the rod. The end piece has two axial drillings 17 through which a pronged tool may be inserted to remove the button by forcing it off the rod. The end of the handle has a concave recess 18 around the button.
Patent ES-358490-A1 (ES)
Title: Method of forming fibertapes using rotating mating pressure rolls
IPC: D02G3/40
Filed: 1968-09-25
Abstract: Textured filament yarn is produced by introducing staple fibres and a tacky polymer substrate between a pair of rotating pressure rolls having continuous circumferential grooves and positioned face to face so that each male member of the grooved surface of one roll fits into the corresponding female member on the other roll to form at the nip point of said rolls cavities adjustable in depth and having shearing edges adapted to separate the resulting staple fibre-polymer composite into a plurality of tapes, with simultaneous consolidation of the tapes within said cavities. The grooves are preferably of substantially square cross-section and the rollers may be cooled. The polymer may be supplied as a continuous film or as a sheet of filaments. Preferably the rollers rotate at a rate faster than the feed-speed of the polymer, whereby orientation is effected. In one embodiment, two sets of filaments may be supplied, one of which is fully oriented and the other of which is fresh-spun and still tacky, and at least one of each type of filament is fed to each cavity. In a further embodiment only fully oriented filaments are fed, and these are heated to render them tacky, but without loss of orientation, as they are fed to the rollers. The staple fibres may be supplied randomly oriented, or lined-up, e.g. by means of electrostatic parallelization. Specified polymers are nylon, polyethylene and acrylonitrile.
