Abstract: Komprimator for emballasje, særlig for emballasjebokser (9) av platemetall med en mantelflate, innbefat-. tende en stilling (25) for boksen (9) med en innmatingsåpning for den ukomprimerte boks, en utmatings-åpning. (30) for den komprimerte boks og to innbyrdes. motstående vegger (29) som er innrettet til ved hjelp av en kraftanordning å forflyttes slik at avstanden mellom veggene motsvarer det tiltenkte komprimerings-. mål for boksen, idet mantelflaten etter komprimeringen vil ha antatt en belgliknende form. Utmatingsåpningen (30) er innrettet til å slippe gjennom en komprimert boks men ikke en ukomprimert boks og er slik belig-. gende i forhold til veggenes (29) endestilling at boksen i sin komprimerte tilstand søker å falle ut gjennom utmatningsåpningen mens den før komprimerin-. gen får støtte.

Abstract: Hurtigkoplende sikkerhetskrok bestående av hendel (15) med mottaker som låses til hunndelen (7) av hakene (2) som i låst stilling virker som kiler. Ved at hakene (2) er plassert utvendig får en maksimalt areal i låsesonen slik at dimensjonene blir minimale. Kroken som er sirkulær tåler samme sidelast i alle stillinger. Handelen låses til wiren (11) med kilen (13) og wirelåsen (14). Som beskyttelse for så vel vann og forurensing som hender brukes kappen (12) til lukking. Hendelen (15) styres lett ned i hunndelen (7) ved hjelp av trakten (1). Låsing skjer ved at haken (2) presses inn i mothaken på handelen (15) ved hjelp av den elastiske fjæren (3) og fjæren (e) (6). Hakene er opphengt i hakeholderen (4) av akslinger. Hake- holderen er festet til utlasningshuset (5) slik at når delene er avlastet, kan utløsningshuset (5) dras ned og hakene (2) går da inn og tillater handelen (15) i å kunne bli dratt ut.

Abstract: A method and an electronic slide gauge serve to measure a length. The slide gauge comprises a rod with a longitudinal marking and a cursor, which is arranged on the rod in a longitudinally displaceable fashion and has two sensors that are mutually offset in the longitudinal direction in such a way that the zero crossings of the signals generated by the sensors do not coincide. In order also to be able to measure lengths in the presence of a considerable DC drift, the zero crossings (ND) of the signals are determined by firstly determining the maximum values (MX) and minimum values (MN) of the signal values (U) and then determining the zero crossings (ND) as an arithmetic mean value. By averaging a relatively large number of zero crossings, the respective zero level (UN) is then determined. <IMAGE>

Abstract: In a stator earth leakage detection process, clear differences in the third harmonic in the faultless and in the earth leaking state may be ascertained but the parasitic current is nevertheless shunted and the vibrations is dampened. For that purpose, a three-phase current transformer (2) is connected to the terminals of a three-phase current machine (1), for example a synchronous generator. The three-phase current transformer (2) must have a free magnetic short-circuit in order to transmit a null voltage in the event of an earth leakage of the three-phase current motor (1). The primary winding of the transformer (2) is star connected with an earthed star point. The secondary winding of the transformer (2) is connected so as to form an open triangle and is loaded with the resistance (4) which may be switched off by the switch (5) connected in series. A voltage converter (6) is connected to the earthed star point of the three-phase current machine (1). The secondary voltage of said converter (6) and the voltage at the open triangle winding are supplied to a static earth leakage relay (7) that detects an earth leakage in the generator (1) on the basis of the amplitude and phase position of the third harmonic in said voltages.

Abstract: A thermo-keratoplasty system and method for locally heating and reshaping a cornea in a manner that produces a minimal regression of the corneal correction. The system includes a probe (12) that is coupled to a power source (14) which can provide a predetermined power, frequency and time duration that creates a thermal profile within the cornea which extends from the epithelium into the corneal stroma. The electrical return of the probe is a lid speculum (202) which maintains the eyelids in an open position. The probe (12) is placed into contact with the cornea and energy is transferred from the power source (14) to the eye, through the lid speculum (202) and back to the power source (14). The energy from the power supply is focused by a probe tip (240) that locally heats and denatures the cornea, and causes a subsequent shrinkage of corneal tissue. A pattern of denatured areas can be created around the cornea to correct the vision of the eye.

Abstract: The cellular communications system includes CDMA and diversity combining with control handoff. The system has a number of mobile switching stations (MSC) connected to each other and the PSTN. These stations are connected via base stations (BS) to a mobile station (MS). An MS (30) is normally linked to the PSTN via a BS (24) an MSC (14). When the MS detects a valid pilot signal from another BS (22) it signals its MSC which establishes a diversity link (82,72,50) via another MSC (12). When the signal becomes too weak the first base station relinquishes control.

Abstract: When cleaning a barrier filter, comprising a plurality of filter elements, of woven fabric of felt, arranged to separate particles out of a polluted gas, the filter elements are cleaned, separately or in groups, by pressurized air pulses, the frequency, the maximum pressure and the duration of which are varied in order to minimize, by an adjustment, the total emission of dust. The frequency and/or the maximum pressure and/or the duration of the cleaning pulses are varied for a group or a plurality of groups of filter elements. After each cleaning pulse, the maximum value for the instantaneous emission of dust, the emission peak, is determined and the emission peak is used, after cleaning a certain group of filter elements, for selecting the frequency and/or the maximum pressure and/or the duration of the cleaning pulses for this group of filter elements during continued operation.

Abstract: A road sign employed for dividing the central line or sectional lane is provided, in which an integrated flange (33) largely increases the area of lower body (10), and a separate sheet (40) is installed in an assembled condition. Even though the road sinks with its top surface seriously bent, therefore, the upper body (20) or the total upper and lower bodies (20) and (30) are easily detached and reused. Furthermore, according to the present invention, a separate support 50 or 50' is interposed between the upper and lower bodies (20) and (30) or between the upper and lower bodies (20) and (30) and the sheet (40) so as to heighten the road sign, which would be continuously used in a heightened status. And the reflective mirrors (25) assembled to the bodies are easily replaced new ones, in such a manner that the use of raw material is minimized, and that the road sign is reused, not buried in the road, to thereby protect the natural environment.
