The invention relates to a two-ply airbag consisting of a textile surface structure, said plies lying opposite one another and enclosing at least one chamber that can be filled with gas. The piles have surfaces that face outwards. The airbag is characterized in that coatings, which are suitable for sealing and reinforcing the airbag, are applied to said surfaces.

The disclosure relates to a textile construction for using in passenger restraint systems including air bags, side curtain air bags and air belts. The textile construction is characterized in that it contains plastically deformable filaments which enable the surface of the textile construction to increase when air pressure is applied and to further increase when stuck by an object such as a passenger. The textile construction is also provided with an especially elastic coating.

A method of fabricating an inflatable seat webbing, more particularly for a seat belt, comprising the steps of weaving a two-ply fabric having an upper ply and a lower ply, folding and placing outermost outer parts on adjoining parts so that all parts are located in sequence above or below a middle part to result in, as viewed in a warp direction, the configuration of a collapsed concertina, and tucking the middle part to the left as viewed from a predetermined direction in relation to fabric threads so that the upper ply and the lower ply of the middle part formerly facing each other now face outwards and sandwiching the folded outer parts and the middle part in between.

A device for clamping and guiding crocheting needles for a crocheting machine. On the one hand a clamping device for the crocheting needles and on the other hand a knock-over comb are to be created, which permit a very fine spacing. To this end, in the bottom part (27) and in the clamping cover (29) of a clamping device (12), opposite, straight needle beds (73, 74) are arranged closely together. The needle beds (73, 74) have wall surfaces that are inclined in a V-shape. A knock-over comb (20, 80) fixed to the machine has upwardly projecting teeth (86) for the crocheting needles. The spacing of the needle beds and guide elements is at least 12, in particular 14 per centimeter of machine width. The holding bar (23) fixed to the machine and the bottom part (27) of the clamping device (12) have recesses, in particular chambers (77, 76) that face one another, which permit the clamping device to move too close to the teeth (86).

A method of detecting hydrolase activity using as substrates the compounds of the formula ##STR1## wherein each of R.sup.1, R.sup.2 and R.sup.3 is C.sub.1 -C.sub.4 alkyl, or phenyl optionally substituted in the meta- or para- position by C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy or mono- or di-(C.sub.1 -C.sub.6)-alkylamino, or optionally substituted by an O-X group in which X is a glycosyl, phosphate or acyl moiety of a natural substrate of the corresponding glycosidase, phosphatase or esterase.
摘要:
A clamping device for attaching crochet needles to the needle bar of a galloon crochet machine or Raschel loom. The clamping device consists of two body pieces, a lower piece and a clamping lid, which are fastened together by means of clamps. In one embodiment the body piece holds the needle shafts, a spacer inserted into each interval between needles, and a support piece between the shafts of a needle and a receptacle in the lower piece. This results in the formation of needle beds. In the other embodiment very shallow grooves are milled opposite one another in both body pieces. These are only a fraction of half the height of the needle shafts, leaving the major part of the needle shaft's height free after clamping.

The invention relates to a method for weaving a webbing, comprising at least one first (right-hand) weft thread and at least one second (left-hand) weft thread, characterized in that the two weft threads are introduced into the same shed from both sides of the webbing, are wound around weft thread retainers in weft change loops, are substantially retained by the weft thread retainers until shed change and are then stripped off from the left thread retainers by the reed and after shed change and are bound against the stop.

The invention relates to a building board or a building element having a multilayer structure, preferably wood-based and consisting of at least three bonded to each other layers, wherein a layer (5) is made of a material, preferably wood-based, which consists of vertically oriented (fv) vertical fibres (50) and is formed as a core layer between two covering layers (3, 4) made of a layer, preferably wood-based, material, the vertical fibres (50) are oriented substantially in a vertical direction with respect to the main extension (ed) of the covering layers (3, 4), in the preferred embodiment, the vertical fibre layer (50) comprises a plurality of vertical cavities (6) which completely transverse said layer and are oriented in a direction (hv) in conformity with the vertical orientation (fv) of the vertical fibres (50) of the material, preferably wood, of which said layer (5) is made. A method for producing the inventive building boards and elements is also disclosed.

The invention relates to a method for producing tissue with the aid of a weaving loom comprising a stop bar, at least one shed and a heddle for carrying out said method. The inventive method is characterized in that warp thread guiding a filling yarn cooperates with a longitudinal heddle connected to the filling yarn and is arranged between said filling yarn and the stop bar of the weaving loom. The warp thread passes through the filling yarn and a longitudinal heddle controlled by a Jacquard device which carries out normal yarn up-and-down movement (down-and-up). Two superposed wefts which are arranged below and under the shed are simultaneously inserted therein. In order to produce a visible section of the filling yarn above a tissue layer (pattern) during the descending (ascending) movement of the filling yarn, the longitudinal heddle is displaced in an ascending (descending) position by the Jacquard device in such a way that the longitudinal heddle provided with a corresponding eye whose lower (top) end is in the center of the shed (central position) prevents the warp thread guided by the filling yarn from moving downward (upward) beyond the shed center, and the lower (top) weft is located outside said shed is inserted.
