Title: Ammonium tungstate prepn. from calcium tungstate material - by redn. to tri:calcium tungstate and then treatment with ammonium ions
Inventor: KASSERRA HANS PETER
IPC: C01G41/00
Filed: 1977-12-30
Abstract: Ammonium tungstate is made by heating Ca tungstate material at 900-1300 degrees C, in presence of a reducing agent, to form tricalcium tungstate and/or metallic tungsten. The obtd. material is treated with an aq. soln. contg. NH4+ ions and anions selected from CO32 and/or HCO3-ions at 30-70 degrees C in the presence of an excess of oxidising agent. The quantity of NH4+ ions is sufficient to react with the W values to form ammonium tungstate which is soluble in the soln. and the quantity of anions is sufficient to react with the Ca to form an insoluble Ca. cpd. The insoluble is then sepd. from the ammonium tungstate soln. The process may be operated as a batch and/or a continuous process Wolframite, scheelite, and/or Ca tungstate ores can be treated opt. in presence of Ca donor cpd. to produce ammounium tungstate which can subsequently be used to obtain, by redn., W trioxide or metallic W. The process is pollution-free and nay contaminants in effluent streams may be treated by known techniques.

Resistors (c) are then covered with lacquer (d); and electroless- or electro- plating is used to deposit a good conducting metal (e) for conductor paths. The thin layer (a) pref. has a sharp edge after removal of the first photolacquer with a usual solvent, e.g. acetone. Method avoids etching processes which involve metal recovery and pollute drain water.

Title: Electrostatic copier processor control - uses logic circuitry in central processor with ROMs and RAMs to control facilities selectable
Inventor: SHIMIZU KATSUICHI
IPC: G03G21/14
Filed: 1978-03-02
Abstract: The image processing appts. has various interrupt-handling capabilities when image formation is interrupted. In one aspect, image formation is interrupted after completion of a set number of image formations when the size of a recording material is indicated as a first size, and image formation is interrupted after a completion of a predetermined number of image formations when a recording material is indicated as a second size. In addition a condition for image formation is selected whereby in the case the selected condition is prevented (e.g. recording on wrong-sized paper), the condition is stored, and after the image formation has commenced, a stop command is inhibited and stored. Additionally data concerning image information is entered, the entered data is displayed, and images are formed sequentially in accordance with the data whereby the formation of the images may be interrupted and the remaining number of image formations may be stored and displayed. It is also possible to interrupt the image formation for a predetermined image formation count without entry by the operator.

Title: Alloyed metal prods., esp. steel - with zones of martensite and ferrite creating internal stresses opposite to the stress to which the prod. is exposed during use
Inventor: SEYBOLD ROLF PROF DR ING
IPC: C21D1/00
Filed: 1978-07-05
Abstract: Load lines are first determined to represent the tensile and compressive stresses to which the prod. will be subjected in service. A composite prod. is then made contg. zones of different alloys bonded together and parallel with the load lines, and a heat treatment is applied the composite prod. so the different zones try to assume different volumes. In the case of steel prodns., zones of different carbon content are pref. used, so that on quenching some zones form a BCC martensitic lattice (I), whereas other zones assume a FCC ferrite or pearlite lattice (II), esp. a ferrite lattice contg. little or no pearlite. The different zones are pref. formed by either deposition welding; or by exposing a prod. to a gas atmos. via which an alloying element is added to the prod. which is partly masked so the element only enters some zones. The tensile- or compressive strength of the prod. is increased so its load carrying capacity is greatly increased.

Title: Improvement of dry, nutrient-poor soil - by incorporation of burnt, capillary-structure granulate of a mixt. of powdered clay and fertiliser
Inventor: FRANKE HANS GEORG
IPC: C05G3/00
Filed: 1979-05-23
Abstract: New method for cultivation and recultivation of dry, nutrient-poor soils (esp. karst soils or dessert soils) involves incorporation into the soil of burnt granulates, exhibiting a capillary structure, of an intimate mixt. of clay particles and fertilizers. The new soil improving agents pref. contain ca. 0.5-35 wt.% fertilizer. The granulate is pref. produced using finely ground clay in a pelleting drum or dish. Burning of the granulate is pref. carried out at 480-1260 degrees C; the burning process imparts a capillary structure to the granules. The agents are pref. incorporated into the soil at different depths to cater for plants having different root lengths. Since the plant roots tend to concentrate around the fertilizer-contg. granules and to penetrate into them, the granules act as an anchor for plants under adverse conditions.

Title: Printing press alignment control system - has tensioning devices both sides of marking station formed between cylinders
Inventor: BAYLEY BARRY J
IPC: B65H23/188
Filed: 1979-06-29
Abstract: The alignment control system for a printing press, has a mechanism forming markings in predetermined positions in relation to each other on a previously-marked strip of material. The markings are formed by clamping pressure in a marking station, upstream and downstream of which are first and second tensioning devices. These maintain tension independently of each other, at a constant ratio between the inlet and outlet side of the clamping point, the latter being between printing and pressure cylinders. One of the devices is controlled by a tension accumulator. A control unit delivers a correction signal on the occurrence of any alignment error, causing a mechanism to alter the speed of the strip through the clamping point.

Title: Phosphate component baking system - adjusts grid speed in heat-equalisation zone to keep layer thickness constant
Inventor: LOS CORNELIS JAN
IPC: C01B25/01
Filed: 1979-09-24
Abstract: The system dries, bakes and cools shaped components of raw phosphate using travelling grids, the components being tipped onto a first grid and transported through drying, baking and hardening zones separated by partitions. They then pass into a heat-equalisation zone between the two grids, and are finally cooled on the second one. Hot waste gas flowing downwards is used in the drying zone, and they are then baked by downwards-flowing heated gas. The hardening zone is heated to the necessary temp. for setting the merely initially dried components by a weak downwards current of gas. Cooling is by air flowing upwards. In the heat-equalisation zone the height of the layer of components is continuously measure, and if it changes the speed of the second grid is altered to correct matters.
