Title: Knotless netting mfr. - in which bonding points are formed by bobbins when braiding heads come together
Inventor: HOLM WILFRIED DR ING
IPC: D04C1/06
Filed: 1980-12-17
Abstract: In the structure of a knotless and braided netting, using a four-thread yarn, the bonding points are formed by the machine so that after the legs of the netting opening have been developed by the displaced braiding heads, the two adjacent spindle drives of the neighbouring braiding heads have their axes either at right angles to each other or straight. The bobbins to develop the bonding points travel a figure-of- eight path, and cross over where the two spindle drives lie next to each other. The bonding point is started when the bobbin forming the leg with the neighbouring spindle drives finds itself at the adjacent braiding head. The process gives an economical method of forming the netting bonding points, with a secure join.

Patent DE-3143756-A1 (DE)
Title: Rotary-chamber vibrating mill
Inventor: GOCK EBERHARD
IPC: B02C17/14
Filed: 1981-10-30
Abstract: The invention disclosed is based on the object of influencing the conveyance of material for milling in conventional vibrating mills by means of constructional measures in such a way that the reduction in the efficiency due to demixing effects, which result in preferred stress zones, is avoided. This takes place according to the invention by virtue of the fact that a freely movable insert constructed as a chamber wheel is moved into the milling container when filling with grinding bodies, which container carries out movements which are synchronous with the filling with grinding bodies on condition that there is an adequate filling level of grinding bodies during the milling operation and, with this rotary chamber effect, brings about a concentration compensation of the material for grinding over the entire volume of the mill. As is proven, the energy requirement for the rotary-chamber vibrating mill is at least 39% smaller in comparison with vibrating mills of conventional design with the same intended degree of comminution.
Patent DE-3143912-A1 (DE)
Title: Pin-removal device
Inventor: VEIHELMANN TRAUGOTT
IPC: H05K3/46
Filed: 1981-11-05
Abstract: The invention relates to a pin-removal device, which can preferably be used for removing the centring pins from platens. Such platens (2, 3) are used for pressing multi-layer circuit boards. The platens (2, 3), which have a large number of bores, are guided through under a row of plungers (6). Certain plungers (6) are actuated, which are then guided through the bores (17) in which a centring pin is located. The remaining plungers do not penetrate the platens. To remove the pins completely, the platens are guided through step-by-step under the plungers. The activation of only quite specific plungers is effected by means of a searching device (8) which detects the presence of centring pins. The invention makes possible automatic pin removal from platens while ensuring that the material to be pressed between the platens remains intact. <IMAGE>

Title: Method of operating an electroplating apparatus
Inventor: BIRKLE SIEGFRIED DR
IPC: C25D17/20
Filed: 1981-12-21
Abstract: The earlier patent P 3127390 relates to an apparatus for continuous electroplating in which the electroplating bath has a horizontal, rotatable plating drum which has open ends and contains guide means for moving the objects to be electroplated through the drum from an input station at one open end to an output station at the other open end of the drum. In said apparatus, only limited variation of the coating thickness as a result of altering the speed of rotation and current density for given drum dimensions (length, diameter) is possible. According to the invention, for given drum dimensions the coating thickness deposited can be varied as desired by filling the drum only over a section of its length with the products to be electroplated and moving the products to and fro one or more times by changing the direction of rotation of the drum. Quasi-continuous operation can be achieved by controlling the supply of objects to be electroplated and the cyclic change in the direction of rotation of the drum in such a way that the objects to be electroplated move back and forth in the drum.

Title: Sealing closure for an orifice in a chamber having a door
Inventor: MAKHIJANI RAJU T
IPC: F16J13/08
Filed: 1982-09-04
Abstract: What is described is a sealing closure for an orifice in a chamber having a door, the closure being pressure-tight. By means of the novel sealing closure, the door can be moved between positions in which the door is located opposite the orifice of the chamber, in which it seals off the chamber and in which it allows access to the chamber. For this, there are provided a driving element and an actuating means which have cooperating surfaces, in such a way that the actuating means is moved in two separate directions. During the movement in one direction, the door is brought into the position in which it is located opposite the chamber orifice. During the movement in the other direction, the door seals off the chamber. Also described is a device which is such that the door can assume its sealing position only when it has previously been ensured that the door cannot move away from the chamber orifice. This prevents the possibility that an undesirable pressure will build up in the chamber.
