Abstract: A filter device for extruders and injection moulding machines designed to process thermoplastics, comprising filter elements that are fitted in at least two separate ducts of a housing between at least one main admission duct and one main exit duct and are interchangeably mounted in sieve carrier bolts in sieve openings that can be moved inwards and outwards with said sieve carrier bolts in the respective bore hole of the housing. At least one locking mechanism is provided in the vicinity of the main admission duct upstream from the sieve carrier bolts. When in a flow position, the locking mechanism does not impede the flow of plastic from the main admission duct to the filter elements. However, when the locking mechanism is in a locking position, the flow of plastic in a partial admission duct is separated from the main admission duct, whereby a) the filter elements in the sieve carrier bolts are configured in an oval shape in a manner that is known per se, whereby the long axis of the oval extends in the direction of displacement of the sieve carrier bolts and the length of the oval axis of the filter elements in relation to the length of the housing bore hole is selected in such a way that only the length of the sieve carrier bolts required to seal the sieve carrier bolts in the housing bore hole is devoid of filter elements and b) the partial admission ducts for each sieve opening open out into at least two flow ducts.

Abstract: A clamp is shown for holding a log of paper while a log-saw or cutting machine cuts shorter lengths of toilet-paper rolls or rolls of kitchen towels or similar all-purpose wipers from the log. The clamp is arranged adjacent a seat or support for the log as well as adjacent a cutting blade. The clamp includes, for each log seat, and on opposite sides of a cutting plane (T-T) through which the blade passes, a pair of adjustable and symmetrically arcuate strips (212, 214) secured to supports (207, 209). The strips are of flexible material with end portions which tend to spring outwardly. A strap (222) is anchored to a retention holder (224) and an adjustment holder (246). The strap surrounds the pair of strips (212, 214) and can change the arrangement thereof. A drive (240, 262, 218) simultaneously adjusts both the length of the strap (222) and the symmetrical angular orientations of two appendixes (228A; 228B) and, consequently, of two cradles (518) on which the strips are supported.   <IMAGE>

Abstract: Det er tilveiebragt et krafttransmisjonssystem hvor en driveffekt blir overført fra en drivkilde til en skruetransmisjon (318) for å rotere en skruetransportør, og en snøblåser (321). En overbelastningsbeskyttelsesmekanisme (317) er anordnet mellom snøblåseren og skruetransmisjonen, for å absorbere overbelastning som utøves i en kraftleveringsbane mellom drivakselen og skruetransmisjonen. På denne måten blir snøryddeoperasjonen ikke avbrutt selv når kraftleveringsbanen blir utsatt for overbelastning. Overbelastningsbeskyttelsesmekanismen kan for eksempel enten en friksjonskopling (317) som anvender et mangfold friksjonsplater eller en gummikopling som anvender buffergummier. Overbelastningsbeskyttelsesmekanismen befinner seg i et stort rom mellom skruetransmisjonen og snøblåseren hvilket gjør det mulig å utnytte det eksisterende rommet på en effektiv måte.

Abstract: A microelectromechanical system (MEMS) steerable electronically scanned lens array (ESA) antenna and method of frequency scanning are disclosed. The MEMS ESA antenna includes a MEMS E-plane steerable lens array and a MEMS H-plane steerable linear array. The MEMS E-plane steerable lens array includes first and second arrays of wide band radiating elements, and an array of MEMS E-plane phase shifter modules disposed between the first and second arrays of radiating elements. The MEMS H-plane steerable linear array includes a continuous transverse stub (CTS) feed array and an array of MEMS H-plane phase shifter modules at an input of the CTS feed array. The MEMS H-plane steerable linear array is disposed adjacent the first array of radiating elements of the MEMS E-plane steerable lens array for providing a planar wave front in the near field. The H-plane phase shifter modules shift RF signals input into the CTS feed array based on the phase settings of the H-plane phase shifter modules, and the E-plane phase shifter modules steer a beam radiated from the CTS feed array in an E-plane based on the phase settings of the E-plane phase shifter modules.
