Patent DE-3002163-A1 (DE)
Title: Continuously operating tube draw bench - has pneumatically operated auxiliary draw carriages
Inventor: HOELZERMANN WINFRIED ING GRAD
IPC: B21C1/22
Filed: 1980-01-18
Abstract: A tube draw bench (1) has two draw carriages (2) (3) which operate alternately. Each carriage grips the mandrel (6) in turn and moves it forward whilst the other carriage returns to its starting position to repeat the process. Normally such draw benches require the process to be temporarily halted whilst the jaws of one carriage are released and the jaws of the other carriage are tightened. This delay is obviated by fitting each carriage (2)(3) with auxiliary jaws (4) (5) which are pneumatically operated and keep the mandrel moving whilst the main jaws are stationary.
Patent DE-3002830-A1 (DE)
Title: Metallic impurity, esp. ferric iron, removal from organic phase - by treatment with phosphoric acid during recirculation, esp. in zinc recovery process
Inventor: SCHEFFLER ULRICH DIPL ING
IPC: C22B3/38
Filed: 1980-01-26
Abstract: The process concerns the removal of metallic impurities (I), esp. Fe(III), from the organic phase (II) in solvent extn., which is used esp. for Zn recovery. The Zn is extracted from the aq. phase with (II), which pref. consists of mono- and/or di-aklyl- phosphoric acids with min. 5 C in the organic gps. and opt. an aliphatic or aromatic diluent. Re-extn., is carried out with an aq. acid soln. then (II) is recycled to the extn. stage. The novel feature is that, during recirculation, (II) laden with (I) is treated continuously or periodically with (acid contg.) (ortho)phosphoric acid (III). The process can be carried out easily without great expenditure on appts. and economical operation is possible on any scale.

Simple construction permits load accommodation with min. material used, and withstands corner trickling of stored material.
Patent DE-3009579-A1 (DE)
Title: Precise window mask prodn. in bimetal foil - by etching each layer with different selective etchant to give mechanical support at edge of window
Inventor: TIROCK BERNHARD ING GRAD
IPC: G03F1/20
Filed: 1980-03-13
Abstract: In the prodn of precise window masks from bimetal foil, the pattern is etched in the thick carrier foil with the first etchant (I) as troughs enlarged by under etching, which extend only partly to the front layer. Then the precise window pattern is etched in the thin front layer with another etchant (II), only slight under etching taking place. Finally, the thick carrier foil is etched through from both sides with (I) so close to the upper layer that the edges of the windows in the thin upper layer are still just supported by the robust carrier foil and thus mechanically protected. The masks are useful in the prodn of electronic circuits, e.g. thin film transistor matrices, by vacuum evapn. They are more robust than usual, allow finer patterns to be etched and are made with thinner Au layer.
Patent DE-3011098-A1 (DE)
Title: Precision casting, esp. of metal dental prostheses - where vacuum is suddenly applied to mould cavity so dense castings with fine surface detail are obtd.
Inventor: RICKE HANS-BENNO DR
IPC: A61C13/00
Filed: 1980-03-22
Abstract: The process and plant consists of a mould with a runner funnel, in which a mouldable or castable mass, esp. a metal or alloy, is placed. The funnel stem forms an ingate leading to a mould cavity which has a small dia. pipe in its base. After the castable mass has been melted, a vacuum is suddenly applied to the small dia. pipe via a vacuum reservoir, so the melt flows into the mould cavity at high speed. A pref. mould includes a runner funnel surrounded by an induction heating coil employed to melt metal in the funnel. The small dia. vacuum pipe is not wide enough so it is entered by the molten metal, but this pipe may also be surrounded by a cooling coil. A simple appts. with low energy consumption, where the porosity of the mould has no significant affect on the vacuum due to the use of a reservoir.
Patent DE-3011654-A1 (DE)
Title: Self levelling cement floor finish - is laid using vibrating rod drawn through mortar or cement layer to assist levelling
IPC: E04F15/12
Filed: 1980-03-26
Abstract: Washed sand, cement and fluidiser are constituents of a substance used for cement floor finishes, and rock dust and air pore producers are used as aggregate. In production, sufficient water is applied for suspension to take place in a free-fall mixer, with conveyance through a wormgear pump via a pipe, and largely self- levelling casting on site. Light agitation can be applied for levelling, such as by a vibrating bar or tube drawn horizontally through the flooring layer of fresh mortar. Only simple overlap, without cementing together, is needed for plastic foil sheets used as base.
Patent DE-3014952-A1 (DE)
Title: Agitation of bulk materials with low flowability in mixer - by using two stirrers rotating in opposite directions, esp in mfg. dextrin and similar prods.
Inventor: SCHIRNER ROLF DIPL ING
IPC: B01F7/00
Filed: 1980-04-18
Abstract: The materials possess a large specific surface; and are fed downwards into a gap between two long stirrer shafts, each provided with rows of arms ending in stirrer blades. Shafts are rotated in opposite directions so streams of the material are driven towards each other; and a liq. is pref. added to wet the material. The pref. mixer consists of a long chamber formed by two half cylinders so the cross-section of the chamber resembles a figure-8. Each half cylinder contains an axial shaft; and the space between the shafts exceeds twice the radius of the stirrer arms on the shafts. The peripheral speed of the stirrers is pref. 10-40 m/s. For example in mixing starch with a catalyst acid to make a prod. during dextrin mfr.; or for agglomerating a prod. obtd. by the hydrolysis of starch; or for granulating dextrin.
Patent DE-3019295-A1 (DE)
Title: Start=stop switch for vehicle engine - is mounted on gear lever or steering wheel and has single push button
Inventor: OEJELID GOERAN A R
IPC: F02N11/08
Filed: 1980-05-21
Abstract: The single push button is provided for both stop and start operations. It emerges from a casing which contains the allied solid state controls. Typically this casing is mounted on the gear lever, close to the gear lever knob. The push button is preferably recessed in the casing to prevent accidental operation. The casing is typically of aluminium with ribs to assist in dissipating heat from the internal components. The electrical connections from the control unit are taken down the gear lever for ultimate connection to the starter solenoid, ignition coil, headlamp relay, battery and battery charger. The equipment can thus be inserted into vehicle wiring with relatively small alteration to existing runs.
Patent DE-3022929-A1 (DE)
Title: Universal motor for automatic washing machine - has divided field winding allowing connection for high and low speeds
Inventor: SCHOTEN HENNO DIPL ING
IPC: H02P25/14
Filed: 1980-06-19
Abstract: The field windings of the motor are divided into a number of discrete coils (1,1',2,2') each with a terminal connection (3,3',4,4'). For high speed a small number of effective turns is required thus two coils only need be connected (3,2,2',3'). For the slower speed washing cycle all windings are connected in series. Actual speed regulation is by phase control of the applied voltage. As the coarse speed setting is achieved by the connection of the windings, the amount of phase control needed is small, reflecting only low distortion into the supply voltage.
