A defoamer emulsion, based on organofunctionally modified polysiloxanes, is obtained by mixing one or several more closely defined organofunctionally modified siloxanes and, optionally, finely divided silica, and emulsifying the mixture by means of a low-shear stirrer with water which contains a hydrophilic, organofunctionally modified polysiloxane.

Disclosed herein is a breathable film and a breathable, cloth-like film/nonwoven composite made from the breathable film which is stretch-thinned and bonded to a fibrous polyolefin nonwoven web. Certain thermoplastic films such as, for example, linear low density polyethylene films are difficult to thermally bond to, for example, polypropylene nonwoven webs due to the incompatibility of the two po...

Disclosed herein is a quilted film laminate wherein a film having a plurality of generally parallel slits is laminated to a substrate layer such as a fibrous nonwoven web. Due to processing conditions, once the slit film layer and substrate layer have been laminated to one another, the composite is allowed to retract thereby giving the composite a puckered or quilted appearance with an undulating ...

A locking device for a roll-up blind, gate or door having slats rollable up and down on a shaft, the slats being slidable inside lateral guides, a first of the slats being attached to the shaft and a last slat adapted to rest upon an outer windowsill. The improvement is directed to the fact that at least one of the slats includes along its length a recess for receiving a pivotally movable catch, t...

Removable bullet-resisting apparatus for a vehicle includes a transparent panel which is secured to or disposed adjacent to a vehicle window and a flexible curtain is secured to a bracket to which the bottom portion of the transparent panel is secured. Both the transparent panel and the curtain are bullet-resisting. Both the panel and the curtain are easily installed and easily removed from their ...

The method is for producing moulded polyurethane foam with open pores, in which the ingoing components are mixed suitably and thereafter injected into a closed mould space in a mould provided with ventilating holes or are held in the mould space in an open mould which is then closed. The polyurethane foam with regulatable density is produced by the mould space being set under vacuum during the foa...

A method and apparatus for laminating two pieces of material involves edge bonding. The method includes the steps of: placing pieces of a first material into a fixture on a work platform, depositing a powder adhesive onto any desired zones of each first material piece, such as an edge zone, curing the adhesive to a form ready for bonding, placing pieces of a second material into the fixture such t...

The awning tarpaulin (4) edge is secured to the rotary shaft (3) for coiling, while the opposite tarpaulin edge is secured to a bar (5). The awning, e.g. for a terrace, has arms (6,7) between the support (2) and the bar for the latter linear guidance arm. The arms are coupled to the support by a hinge linkage (8) with adjustable stops for setting the angle between the wall (1) plane and the bar g...

Procédé de contrôle et de réglage de la géométrie de la ligne d'arbres d'un groupe hydroélectrique à axe vertical, ledit groupe étant supporté par un pivot, caractérisé en ce que : - on démonte les paliers de la ligne d'arbres (3,4,5) de manière à permettre une rotation libre de la ligne d'arbres ; - pour chaque arbre (3,4,5), on détermine, dans deux plans horizontaux différents, la position du ce...

A process for the preparation of oligoribonucleotides of the formula in which n, L, BB, W, T, Y', U, C1 and C2 are as defined in the description, by solid-phase synthesis is described, as are intermediates of the formulae and

A scaffold system has a plurality of vertical members and a plurality of cross members connected by couplings. The vertical members and cross members are comprised of polymeric matrix reinforced with glass and polymeric fibres. Each coupling comprises a pair of annular flanges, positioned on the vertical members in a spaced apart relation to form a groove. Each flange is formed with a least oneape...

The subject of the invention is an improvement in the architecture of EPROM OTP memories to permit at least partial reprogramming in which the following functional blocks are connected to an EPROM memory core: - an array register A for the page counter function, which is used to store the position of the current page, a controller to update the page B which permits the user to programme the said a...

Improvement in a complex formwork structure, especially for making columnar concrete elements, consisting of two complementary half-shells, each of which comprises at least two previously assembled elements, given by: - a first outer metal jacket with semicircular cross section; - a second structure associated internally with the first one, being made of expanded polystyrene, likewise having a sem...

Procedure for making picture frames 10, said picture frames 10 having at least one sheet of transparent plastic material 12 and one sheet of opaque material 13, between said two sheets 12, 13 there being positioned the picture frame 19, the two sheets 12, 13 being prepared separately by a method of stamping by aspiration in vacuo, the stamp 15-115 used for the transparent sheet 12 being conjugate ...
