Title: Feeding pot plants with water from below - components include pot support, decorative container and easily threaded wick
Inventor: ROOSWIES ANDREAS MEYER
IPC: A01G27/04
Filed: 1975-12-19
Abstract: The components of an assembly for feeding a pot plant by means of a wick with water fom a dish, comprise (a) a strip of a material which can be rooled up, with a number of fastenings for locking the strip into the form of a cylinder adapted to the size of the plant pot so as to support it at a given height above the level of the water; (b) a second strip, also capable of being rolled up, with fasteners at the edges of its short sides and running parallel to its long edges, a slit from the ends of which folds extend to the edge of the strip, so that when a decorative sleeve is formed by joining the short sides, there is a concave opening for filling the dish with water. The fasteners are pres studs which engage in holes in the strips, and the height of the support strip is less than that of the decorative sleeve, the outer dia. of which corresponds to the inner dia. of the dish. The details may be attractively packed for sale with the strips rolled up and tucked with the wick into the dish, in a transparent sachet. The outer sleeve may have a number of slots and folds so that it can be arrange a multi-sided figure enclosing the plant pot. Provides a decorative container in which any plant pot can be set to the correct height, and the supply of water maintained.

Title: Restraint for head of vehicle passenger - has head impact damping elements activated by deceleration caused forward movement of body
Inventor: BUFLER ERNST DIPL ING
IPC: B60R21/08
Filed: 1976-03-17
Abstract: The safety mechanism is for seat belts in cars. The sudden forward move of the user's head is caught up by a hold-back element released into position by the delayed forward movement of the body. The backrest (5) swivels around a fulcrum (6) and at the same time the seat (2) slides forward. The upper end of the backrest reaches into the roof part of the car, keeping in inactive position the spring loaded linkage (15, 9). Following a sudden acceleration of the vehicle the body retained in upright position by the seat belt (3) moves forward, causing the backrest to swivel and the seat (2) to slide forward. The head of the passenger also moves forward and the passenger is saved from injury due to backlash or impact by netting (10) actuated by a spring (7).

Title: Bowl centrifuge rotor - has casing enclosing coaxial external and internal screw conveyors
Inventor: NOSDROVSKIJ ANDREJ STEPANOVITS
IPC: B04B1/20
Filed: 1976-04-23
Abstract: The rotor comprises a hollow rotary casing having windows for discharge of clarified liq. at one end and sediment discharge windows at the opposite end. The casing houses an external coaxial hollow screw conveyor having a cavity into which the processed suspension is fed from one end of the conveyor. A pack of sepg. plates is placed adjacent and coaxial with the screw conveyor in the path of the flow of the suspension being processed towards the windows in the casing for the discharge of clarified liq. A hollow internal screw conveyor positioned between the pack and the discharge end of the external screw conveyor is rigidly secured to the rotary casing. The discharge end of the internal screw conveyor is oriented in the same direction as the external screw conveyor and sediment from the internal screw conveyor is discharged through windows in the wall of the external screw conveyor. Rotor is capable of sepg. polydispersed suspensions having a high content of fine fractions. The undesirable influence of the quicker settling coarser fractions of the suspension upon the discharge of the finer fractions is avoided by successively isolating fractions of different size.

IPC: C22B15/00
Filed: 1976-07-20
Abstract: The method of winning metals, esp. Cu, from sulphide ores comprises (a) roasting the ore under oxidising conditions at 400-1400 degrees C to remove elemental S; (b) treating the S-free roasted material in a furance at 400-1400 degrees C to reduce the oxidised material or change the structure of the roasted product; (c) leaching the product in a first soln. contg. a ligant to extract the main fraction of metal; (d) sepg. the solids by filtering; and (e) leaching in a second soln. contg. a ligand. Pref the ore is roasted under oxidising conditions at 650-1000 degrees C and then treated under reducing conditions at 750-950 degrees C using as reducing gas a mixt. of CO/CO2 or H2/H2O. The CO/CO2 ratio is such that Zn- and Cu cpds. are formed, the Zn cpds. being leached without extracting the Cu compd. The leaching soln contains Cu (II) sulphate, water and a ligand such as acetone nitrile, acrylonitrile or allyl alcohol. The sulphuric gases formed are utilized for producing sulphuric acid and other waste gases are removed by treating with aq. lime sludge. The starting material may be an oxide ore in which case the oxidising roasting step is not applied, or may be a metal.
