Title: Concrete building element with integrated heating ducts
Inventor: CARL HEINZ ING GRAD
IPC: E04C2/52
Filed: 1982-03-16
Abstract: A concrete building element is described, in which heating ducts for the building heating can be integrated without the formation of cracks being able to occur due to inevitable temperature fluctuations. The concrete building element furthermore has an excellent heat-storage capacity. In a preferred embodiment according to Fig. 1, the concrete building element is designed as a hollow slab of concrete (1) with cavities (3). Situated between the cavities (3) and the boundary face (2a) facing the room to be heated is a layer of a concrete (4) which contains foamed-plastic particles (5) and in which the heating ducts (6) are embedded. The foamed plastic gives the concrete excellent elasticity, which can be further increased by adding conventional foaming agents. <IMAGE>

Patent DE-3241915-A1 (DE)
Title: Labelling station of a labelling machine with a label printing mechanism
IPC: B65C9/16
Filed: 1982-11-12
Abstract: The invention relates to a labelling station for objects such as bottles with a label printing mechanism. The printing mechanism comprises one or more marking elements which roll against an inking roller and which apply the ink they have received to the front of the label, held by the removal elements, in a roll-off process. The inking roller picks up the printing ink, which has a high solvent content and which therefore dries in fractions of a second, directly from a tank. A doctor in the form of a block of foamed material with closed pores is mounted on the outside of the roller to meter out the amount of ink to be applied. The outside of the roller is smooth and of metallic hardness. It preferably consists of steel. A printing mechanism of this kind has the advantage that printing ink which dries quickly and which is therefore immediately smudge-proof can be used without there being a risk of the printing ink received by the outside of the roller drying on the outside of the roller. Immersion of the inking roller in the printing ink causes drying ink to become soluble again. In addition, the reliability of the doctor is not reduced during operation. <IMAGE>

Patent DE-3244824-A1 (DE)
Inventor: MUELLER ERNST DR
IPC: B22D35/04
Filed: 1982-12-03
Abstract: A compact and re-usable ingate device for transferring molten metal to a mold during casting employs a substantially unitary structure resembling a trapezoidal block of refractory material. Within the block are a generally cylindrical rotation chamber, an inlet channel which receives the molten metal and injects it tangentially into the rotation chamber, so that the metal swirls rapidly to separate nonmetallic inclusions, and an outlet channel which conveys the cleaned metal to the mold. The rotation chamber may have a bottom that is positioned below the opening to the outlet channel and walls which slope outward slightly from the bottom to at least the opening, so that inclusions and metal that has solidified at the bottom can be removed from the rotation chamber. Alternately the outlet channel may open into the bottom at an eccentric position, so that all of the molten metal will be drained.

Patent DE-3338156-A1 (DE)
Title: Pot casing, method of and device for closing
Inventor: KLASCHKA RUDOLF
IPC: H01G13/00
Filed: 1983-10-20
Abstract: The invention relates to a pot casing consisting of metal as a semi-finished product, such as is used, for example, for electrolyte capacitors. Furthermore, the invention relates to a method of and a device for diameter reduction and flangeing of such a pot casing. In the conventional way, the diameter reduction of such a pot casing was carried out from below in the direction of the upper, open pot rim. The flangeing is generally performed by a separate device. The invention improves the conventional measures by dry further widening of the wet-prewidened pot casing. As far as the method is concerned, the pot casing provided with the casing widening is then closed axially downwards from the pot rim, in a diameter-reducing manner, this method step being additionally supplemented by a further flangeing step, carried out in the same device. The diameter reduction and the flangeing are in this case performed by a relative axial displacement between cup and device, carried out in the same direction.
Patent DE-3341173-A1 (DE)
Title: Method for rectifying multiphase AC voltages of tachometer generators
Inventor: FRENK HELMUTH DR
IPC: G01P3/46
Filed: 1983-11-14
Abstract: A method is described for determining the peak value from the instantaneous values of a tachometer AC voltage, which yields rectification without ripple: 2 tachometer voltages U0 and U90 shifted by 90 DEG  are integrated and produce US0 and US90 with constant amplitude. The division of the instantaneous values U0/US90 = U90/US0 continuously yield the speed-proportional peak value. The zero crossings are bridged by mutual overlapping. Harmonics remain as ripple; a method for eliminating them is specified along with arrangements for carrying out the method. <IMAGE>
