Title: Preparation of urea-formaldehyde condensates, and the use thereof
Inventor: GOECKEL ULRICH DR
IPC: C08G12/40
Filed: 1983-12-23
Abstract: The invention relates to a process for the preparation of water-dilutable, low-formaldehyde urea-formaldehyde condensates which have a low viscosity and a long shelf life by condensing urea and formaldehyde in a molar ratio of from 1:2.0 to 2.25 in the presence of alkali metal sulphite at a pH of from 9.0 to 10.5 and a temperature of from 80 DEG C to the reflux temperature, and subsequently continuing the condensation at a pH of from 4.0 to 6.0 and at from 70 to 95 DEG C, where from 0.01 to 0.03 mol of alkali metal sulphite are employed per mol of formaldehyde, the condensation at pH 4.0 to 6.0 is carried out with addition of from 0 to 0.2 mol of a water-soluble alkanol per mol of formaldehyde until infinite water-dilutability is just achieved, urea is subsequently added until the overall urea:formaldehyde molar ratio is from 1:1.60 to 1.95, and then from 0.01 to 0.04 mol of glyoxal are added per mol of formaldehyde, and to the use of the urea-formaldehyde condensates as binders for fibre nonwovens made from organic and/or mineral fibres.

Title: Shaft seal
Inventor: JANCOVICH GUIDO
IPC: F16J15/16
Filed: 1984-02-11
Abstract: A shaft seal, especially for centrifugal pumps for delivering hot water, having a slide ring packing arranged in a sealing chamber of the pump cover, and having a cooling and constricting section formed on the pump cover between the pumping chamber and the sealing chamber, and having a secondary fluid circulation in the sealing chamber, which circulation is effected by a conveying element, especially a conveying thread disposed on the slide ring, and which serves for rinsing and additional cooling of the slide ring, is to be improved in such a way that the construction effort and the construction volume are considerably reduced, while the operational reliability is increased. In essence, it is proposed to this end that, as known per se, in the region of the cooling section in the pump cover a cooling chamber is formed, through which a cooling fluid flows, and that within the pump cover the ducts conducting the secondary liquid circulation run through the cooling chamber.

Title: Screen for transmitted-light projection and method for producing a screen
Inventor: STIEF HORST
IPC: G03B21/62
Filed: 1984-04-30
Abstract: Perflectly illuminated images can be produced using the known screens for transmitted-light projection, which are formed from a front image pane made from transparent material and a rear transmitted-light wall. According to the invention, the front image pane and the rear transmitted-light wall are arranged lying against one another in a planar fashion, one or both sides of the image pane or one side of the transmitted-light wall possibly being provided with a reflection layer. In the production of the screen, the first step is to adjust the image pane to a tool, and subsequently to lock the transmitted-light wall in a prestressed position above the image pane and thereafter weld it to the image pane, preferably by means of a circumferential air-tight high-frequency weld, or using a welding liquid as cold weld.

Title: Synchroniser for manual transmissions, in particular for toothed-wheel gear change boxes
Inventor: HOENNEBECK KLAUS SIGURD
IPC: F16D23/06
Filed: 1984-06-08
Abstract: Synchroniser for manual transmissions, in particular for toothed-wheel gear change boxes, in which a friction ring (3) provided with an inner tapered friction surface forms an annular gap with approximately equal gap clearances between its outer circumferential surface (9) and an opposing annular surface (10) of the sleeve carrier (2). Arranged in the annular gap is at least one spring element. This is supported, on the one hand, on the outer circumferential surface (9) of the friction ring (3) and, on the other hand, on the opposing annular surface (10) of the sleeve carrier (2). In addition to centring the friction ring (3), relative movements between the friction ring (3) and the sleeve carrier (2) are thereby to a large extent damped. In order to bring about release of the friction ring (3) when gear wheel (7) is not selected, the annular gap can be of tapered design with approximately equal gap clearances. <IMAGE>

Title: Process and apparatus for pressing elongate filling material into containers
Inventor: WEHRSTEDT VON NESSEN LAPP JOAC
IPC: B65B1/24
Filed: 1985-05-23
Abstract: The invention relates to a process and an apparatus for pressing elongate filling material into containers which have previously been filled and which are to be closed after the filling material has been pressed in. In order to press in the filling material, especially small sausages, gently and reliably, it is proposed, while the filling material is being subjected to pressure, to generate a relative rotational movement about the vertical container axis between container and pressure force and, at the same time, brake the filling material relative to this rotational movement. The protruding filling material is thereby virtually screwed into the remaining container content.

Title: Additional safeguard for slide fasteners on trousers
Inventor: KITZING INGE
IPC: A41F1/00
Filed: 1985-08-28
Abstract: Slide fasteners on trousers which open by themselves are an embarrassing annoyance. In order to stop this happening, a simple additional safeguard has been developed. In the simplest form, this consists of two key rings of different sizes which are joined together. The smaller key ring is hooked into the gripping tab eye of the fastener slider. When the slide fastener has been closed, the larger ring is hooked over the waistband button of the trousers and the buttonhole is fastened over it afterwards. The sequence of fastening the trousers is thus exactly reversed. However, self-opening of the slider is thus prevented. <IMAGE>

Patent DE-3534459-A1 (DE)
Title: Shaft seal
Inventor: SCHULZE ERHARD
IPC: F16K3/28
Filed: 1985-09-27
Abstract: To seal off the passage of a longitudinally displaceable shaft through a wall (11), a one-piece sealing body (13) made of polytetrafluoroethylene is inserted into the hole in the wall (11). The sealing body (13) has a tubular section (15) which projects axially towards the side under pressure and which is surrounded by clamping rings (18). As a result, the force with which the section (15), which forms the sealing gap (21) with the shaft (10), is pressed against the said shaft varies as a function of the pressure. The shaft seal is suitable for very high pressures (up to about 400 bar). <IMAGE>

Title: Device, in particular ball valve
IPC: F16K5/06
Filed: 1985-10-16
Abstract: The invention relates to a device, in particular a ball valve, having a rotary body (8) which has an essentially spherical sealing face (31). The intention is to solve the object of achieving a reliable seal with little production outlay, the intention being to avoid seals made of soft material and, on the other hand, to obtain the advantages of high resistance to corrosion and good abrasion resistance. It is proposed that the sealing element (32, 34) consisting of ceramic have an annular, narrow contact face (36, 38) or contact line. The sealing element (32, 34) which is constructed in this way rests under the effect of a spring force on the sealing face (31) of the rotary body (8). <IMAGE>
