Patent DE-3034707-A1 (DE)
Title: Drum winch with automatic rope guide - has direction sensor for rope section between guide and drum, controlling guide drive according to direction deflection
Inventor: FAUERBACH ANTON
IPC: B65H54/28
Filed: 1980-09-15
Abstract: The rope guide is movable by a drive parallel to the drum axis. It has a direction sensor for the rope section between the guide and the drum. The sensor is coupled to the drive for control purposes such that the guide remains idle until, during the rope (un)winding, a directional deviation of the rope section has taken place w.r.t. a normal plane through the drum axis. The rope guide is set into motion, when the direction deviation has reached a limit value. After equalisation of this deviation it is reset again into its idle position. The direction sensor has preferably a rope balance, mounted on the rope guide and fitted with two sensor rolls, guiding the rope and detecting the direction of the rope section. An electric change-over switch controls the rope guide direction reversal.

Title: Pipe holder
Inventor: STANGE PAUL
IPC: F16L3/24
Filed: 1981-03-19
Abstract: In the construction of pipelines, apparatuses, boilers and cooling systems, holders or slotted supports are inserted into costly screwed, welded and profiled structures for the attachment and guidance of tubes and apparatuses. The main supports and guide straps must either be drilled through and screwed or welded to one another. In the case of pipelines, conversion of pipes to other pipe sizes leads to a multiplicity of support holes. The newly invented pipe holder permits the attachment and guidance or clamping of pipes, supports, apparatuses on profiled supports in any position. It consists of clamping jaws which are clamped firmly around the profiled supports by means of clamping screws and of eyes, having screw holes for the insertion of round-steel clips (Fig. 1.1) or of grooves for the insertion of pipe supports (Fig. 2.1). Sliding plates or discs contribute to the reduction in the friction forces. <IMAGE>

Title: Preparation of gypsum hemihydrate with thermal waste, aqueous H2SO4 and sulphuric acid salts
Inventor: QUANTE HEINRICH
IPC: C01F11/46
Filed: 1981-05-05
Abstract: Alpha-gypsum hemihydrate is an important building material, which is obtained especially by calcination of calcium sulphate dihydrate, which arises in the desulphurisation of a power station flue gas or in the chemical sector, for example in the manufacture of phosphoric acid. A particularly advantageous calcination process comprises first preparing a dispersion of calcium sulphate dihydrate and aqueous sulphuric acid solution in the presence of sulphuric acid salts and then heating this dispersion, while maintaining a predetermined heating-up rate, to about 373 K together with industrial, dust-free thermal waste, whereupon the solid constituents are then separated off from the aqueous sulphuric acid and dried. Due to the combination of aqueous sulphuric acid solution and sulphuric acid salts, the result of this process is an alpha-gypsum hemihydrate virtually without fractions of anhydrite II, which substantially facilitates the processing thereof. Apart from the negligibly small fraction of anhydrite II, the alpha-gypsum hemihydrate product is distinguished, if magnesium oxide is added, by high fineness and absence of any efflorescence phenomena. <IMAGE>

Inventor: HOLLENSTEIN ERWIN BRUNO
IPC: B65D81/20
Filed: 1981-06-29
Abstract: The present invention is with respect to an overpressure valve for packages with flexible walls, having a valve body able to be fluid-tightly joined with such a package. The valve body has a flat valve seat having thereon a diaphragm with a valve shutting part. In the seat there are valve openings, each having a number of concentric ring-like channels round it in the seat. The concentric channels take up a sealant, more specially silicone oil. The diaphragm is made of a single piece of material running on one side of the walls to the other without any holes therein. It is only kept in position in a middle part of the valve seat so that the diaphragm may be moved freely, at least over the valve openings. In the case of a preferred form of the invention, the diaphragm is slipped loosely into the valve body in which it is kept in position by a keeper in a middle part thereof. The keeper may be fixed in position by friction or by a keying effect.

Abstract: A circuit arrangement for recording and replaying the state of play of a sports competition carried out between two parties, particularly of a tennis game, with change of service and sides in accordance with the state of play in each case previously achieved, is constructed in the following manner: two adding counting circuits (Z1, Z2) in each case allocated to one party are incremented by manually inputting a particular value of game points and are connected to a further counting circuit (Z3, Z4) each in such a manner that the carry generated by the first counting circuits (Z1, Z2), is added in one of the further counting circuits (Z3, Z4) in dependence on the state of a memory (V6) which can be constructed in a manner of a change-over switch. The counting circuits are in each case followed by display devices (A1, A2, A5, A4) for reproducing the gain in points or games. The memory (V6) is set by manual input (T2) and is automatically complemented (change of sides) with each second carry, for which a further counting circuit (Z5) can be used which counts the carry pulses of the first counting circuits and complements their output signal with each second carry signal. The first counting circuits (Z1, Z2) allocated to the parties are reset with each carry. <IMAGE>

Title: Wheel gear for floor-working machines
Inventor: WOLFF DIETER DIPL ING
IPC: F16H3/72
Filed: 1982-05-27
Abstract: For a machine for lifting floor coverings bonded to the floor, a wheel gear is specified which permits both uncoupled freewheeling for positioning the machine into its working position and a drive of the machine which is adapted to the particular working load and can be adjusted from freewheeling to complete coupling.

Patent DE-3221414-A1 (DE)
Title: Electric loudspeaker
Inventor: KUTTRUFF HEINRICH PROF DR
IPC: H04R7/02
Filed: 1982-06-05
Abstract: The sound radiation of electric loudspeakers is unfavourably affected at low frequencies by the system resonance, resulting in a restriction in the usable frequency range and a poor transient response. In the present invention, this is prevented by using a diaphragm which is partially air-permeable. If said diaphragm moves, a partial pressure equalisation takes place between its front and rear sides. Due to the finite flow resistance of the diaphragm material and the associated frictional losses, the system is additionally dampened. At the same time, the resonance of the loudspeaker system which is installed in the conventional manner in an enclosed housing is split into two resonances, of which one lies above and the other below the original resonance. This is equivalent to a base reflex effect and therefore to a downward extension of the frequency range. The air permeability of the diaphragm can be achieved, for example, by perforation or by using a porous material. There is a favourable range of values for the flow resistance, but this is not particularly critical.

Title: Method for rolling metal billets
Inventor: POLUCHIN PETR I
IPC: B21B1/46
Filed: 1982-08-20
Abstract: The method serves for the production of round billets and sectional rolling stock composed of ferrous and non-ferrous metals, particularly of continuously cast metals. The method consists in a deformation of a billet by three rolls (1, 2, 3), during which a rotary and feed motion is imparted to the billet due to a rotation of the rolls (1, 2, 3) through a feed angle of 15 to 35 DEG . The rolling of the billets in the deformation zone, which comprises an edging section (C) and a calibrating section (D), takes place with individual reductions in the entry zone (A) of the edging section of 0.2 to 0.5 referred to the maximum possible individual reductions in the deformation zone. Rolling is carried out with a maximum individual reduction of 20 to 40%, the reduction in the entry zone (A) of the edging section being 0.05 to 0.4 referred to the total diameter reduction in each pass. Suitable billets for rolling are those with a non-circular cross-section and a ratio of the maximum dimension to the minimum dimension of from 1.1 to 1.35. <IMAGE>
