  • Patent number: 4397589
    Abstract: The ground anchorage means comprises a reinforcement combined with an adjacent injection tube furnished with sleeves acting as retention valves and a distensible sack intended to obturate the drilled hole. The fixing zone of the reinforcement is protected by an impervious envelope made of a rot-proof and anti-corrosive material in which the reinforcement is immersed in a hardenable material such as grouting cement. The free zone is immersed in an anti-corrosive product, which may be flexible in another envelope or sheath, the two envelopes being joined together by a sealing sleeve. Application, particularly for supporting walls.

  • Patent number: 4395910
    Abstract: Circuitry for generating a distortion-free sector display in a cathode ray tube for displaying signals from an ultrasonic transducer moving back and forth in an arcuate path. Sine and cosine beam sweep signals are developed using signals respectively representing the angular position .theta. of the transducer on its angular path (representing the sine) and 1-.theta..sup.2 /2(representing the cosine). A transducer position signal is stored on a relatively large capacitor, and a capacitor of smaller capacitance is used to generate a ramp signal in producing the sine and cosine beam sweep signals.

  • Patent number: 4385783
    Abstract: A furniture element for use as a seating unit or a component thereof (e.g. a chair back, seat, or arm), comprising an upholstered body foldable about at least one axis into overlapping portions with facing inner surfaces. Each portion of the body includes a panel; the body also includes a cushion disposed outwardly of the panels and extending between them, and a flexible web outwardly covering the cushion with margins extending around the edges of the panels and secured in overlying relation to the inner surfaces of the panels. The element additionally includes at least one trim member (such as a welt), secured to the inner surface of one of the panels around the edges thereof with ends curving toward each other at the locality of folding, and means for fastening the folded portions of the body together. Supporting structure may be mounted between the panels, or at an outer surface of the folded body, for interconnecting the furniture element with other elements of a chair or the like.

  • Patent number: 4384021
    Abstract: A woven fabric tape comprises a main portion and selvage portions provided along both sides of the main portion. The selvage portions are composed of a tissue which is more resistant against fraying than the tissue of the main portion. Each selvage portion of the fabric tape has a fused edge thereby to prevent fraying. A woven fabric suitable for the production of such fabric tapes comprises main portions and selvage forming portions, which are continuously and alternatively woven in a parallel relationship with each other. The selvage forming portions are composed of a tissue which is more resistant against fraying than the tissue of the main portions. The selvage forming portions are made of a thermally fusible material.

  • Patent number: 4379589
    Abstract: A reclinable chair having a back and seat articulated for reclining movement of the back with respect to the seat, in which a plate having opposed faces disposed at an angle with respect to each other joins together the back and the seat. One of the plate faces is joined to the back, while the other of the plate faces is joined to the seat. A restoring force is exerted by the plate tending to restore the plate faces to the angle therebetween when they are forced away from that angle. The plate is preferably U-shaped, substantially encased in resilient material also U-shaped, with a flap of resilient material extending parallel to and between the legs of the plate.

  • Patent number: 4378416
    Abstract: A photosensitive member used for an electrophotographic copying process includes an electrically conductive layer and a photosensitive layer formed thereon. The photosensitive layer has a surface region which is subject to an imagewise exposure to form an electrostatic latent image thereon which corresponds to an effective image area on an original which is to be copied. An area of the photosensitive layer other than the surface region which corresponds to the effective image area to be copied represents a photosensitive layer portion which substantially functions as a photosensitive member during a copying process, for example, during a charging step. The photosensitive layer portion is provided with a layer of an electrically conductive material.
