Patent DE-3318800-A1 (DE)
Title: Element for attaching components to a wall
Inventor: GRAEWE BERND
IPC: E04F13/08
Filed: 1983-05-24
Abstract: An element for attaching components, especially light components such as foam bodies, to a wall is intended to be given a construction which is insensitive to corrosion influences. The attachment element 31 in this case consists of a plastic-sleeve dowel 1 which can be inserted into a hole 36 in a wall 34, and of a dowel nail screw 18, which can be driven through a hole 33 in the component 35 into the plastic-sleeve dowel 1 and whose head 21 engages over the component 35 at the outer end of the hole 33. The dowel nail screw 18 is firmly extrusion coated on its rear shank part 24 with a plastic sleeve 25 which forms a disc-like or plate-like head 26 and, at a distance from said head, at least one annular shoulder 27. Each plastic sleeve 25 is in turn provided with a circumferential constriction 30 in front of this annular shoulder 27. At its free end, the plastic-sleeve dowel 1 has an expanded opening 13 whose internal diameter is matched to the external diameter of the plastic sleeve 25 and whose depth is at least equal to the length of the part of the plastic sleeve 25 located in front of the annular shoulder 27. Located inside the expanded opening 13 is an annular bead 15 by means of which the annular shoulder 27 of the plastic sleeve 25 is pressed over the circumferential constriction 30, which is supported in front of it, against the end surface 17 of the plastic-sleeve dowel (Fig. 4). <IMAGE>

Title: Circuit arrangement for supplying the cathode heater of tubes
Inventor: HORNECKER KURT
IPC: H01J1/13
Filed: 1983-07-22
Abstract: It is known for the heater of a television camera recording tube to be supplied from a constant-current source, in order that the tube receives the correct heater power irrespective of the lead length and the lead resistance. The supply voltage of such current sources is in general much higher than the permissible heater voltage so that, if this voltage is applied to the tube heater in the case of a defect in the current source, the tube is destroyed. The protection circuit according to the invention against an overload of the tube heater is for a fuse (SI) to be connected in the supply lead to the current source. A switch (TH) is connected in series with said fuse, which switch carries a current, in the closed switch position, which causes the fuse to trigger and which is controlled by a voltage monitoring device (Z2, R12, TS4) which is connected to the cathode heater (H) and closes the switch (TH) when the voltage on the cathode heater exceeds a predetermined value. The main field of application of the invention is television recording tubes. <IMAGE>
Patent DE-3329578-A1 (DE)
Title: Pore-containing polyvinylidene fluoride mouldings
Inventor: JOSEFIAK CHRISTOPH DR
IPC: B29C48/06
Filed: 1983-08-16
Abstract: An improved process is described for the production of pore-containing mouldings, in particular membranes, from polyvinylidene fluoride (PVDF). To this end, a single-phase liquid mixture of PVDF and one or more mixture components is forced through a nozzle into a cooling device. Cooling of the mixture is accompanied first by separation into two liquid phases, and then by solidification. The cooling device contains a cooling liquid whose mean velocity in the device is significantly lower than the velocity at which the PVDF mixture emerges from the nozzle. The liquid level is kept constant at the PVDF mixture inlet and outlet. The PVDF mixture passes through the device from top to bottom, at least until the point at which solidification begins, and only then is it diverted in order to pass through a second zone from bottom to top. The process steps enable the mechanical load on the PVDF mixture to be kept very low until it starts to solidify. This enables even relatively low-viscosity mixtures to be processed. The pore-containing PVDF mouldings are suitable for microfiltration, in particular even of chemically aggressive media, and for transmembrane distillation.

Abstract: The invention relates to an electronic motor for driving, especially, dentists' tools. In order to avoid the disadvantages of known electronic motors using analogue sensors, for example Hall probes, especially in order to keep the power loss low, it is proposed in the case of a motor having a three-phase stator winding and three binary-switching sensors which are in each case arranged phase-shifted through 60 DEG  or 120 DEG  with respect to one another, to provide a logic circuit (I1 to I3; UG1 to UG6) which supplies (Fig. 4) six drive signals from the three sensor signals (Fig. 3), by means of which six switching transistors (T1 to T6), which are allocated in pairs to the windings (W1 to W3), are driven such that they are in each case on for 120 DEG , the transistor pairs (T1/T2; T3/T4; T5/T6) being off for 60 DEG during the zero-crossover of the e.m.f., the off phase of the transistor pairs being shifted through 120 DEG  with respect to one another. <IMAGE>

Abstract: The invention relates to a method and a device for producing a jewellery link chain, in which there are chain links which engage in one another at least partially, at least in pairs, such as is the case in a byzantine chain or royal chain. In accordance with the proposal according to the invention, such a chain is produced by machine in that an intermediate link, constructed as an individual link, and pairs of double links, formed in each case by two individual rings are shaped with the aid of a fixing mandrel, a separating mandrel, a joiner and a bending mandrel as well as an outer head with pincer jaws arranged in pairs and an inner head with inner jaws arranged likewise in pairs and arranged offset by 90 DEG relative to the outer jaws. Said intermediate links and pairs of double links are then joined together to form the chain. <IMAGE>

Abstract: A vibratory dry-shaver comprises a shear foil having two longitudinal edges, and respective means to clamp the two longitudinal edges in place to cause the shear foil to assume a natural curvature, the tangents to such curvature at the two clamping means forming an acute angle with each other. A cutter is reciprocatingly movable along and adjacent to the shear foil, the cutting edge of the cutter having a curvature corresponding to that of the clamped, curved shear foil. The curved shear foil and the cutting edge of the cutter each have a hyperbolic cosine curvature according to the formula: y=cxcosh x/c where y indicates the distances of the individual cutting edge points from the x-axis, x is the coordinate in the direction of the width of the cutter, and c is a constant derived from the width 2b of the clamped shear foil and the height of the curvature h of the clamped shear foil.

Patent DE-3416883-A1 (DE)
Inventor: MASSEN ROBERT
IPC: G01B11/02
Filed: 1984-05-08
Abstract: For the continuous contactless measurement of the shrinkage of textiles during the production process, the image of a portion of the textile surface is picked up both before and after the shrinkage and converted to analog electrical image signals by means of an image/signal transducer. The analog image signals are digitized by analog-digital converters and stored in image signal memories. A calculating unit determines from the stored digital image signals the periods of the textile structure both before and after the shrinkage in at least one evaluation direction, preferably in the longitudinal direction and in the transverse direction of the textile web. The change of length of the textile material in each evaluation direction is calculated from the ratio of the two periods determined in this direction. The method is in particular suitable for the measurement of the two-dimensional shrinkage of knitted textiles during the manufacturing process.
