Patent DE-2547028-A1 (DE)
Title: Foodstuff container enclosing heater or lamp - has adjustable screw clamping ring with extension support arms
Inventor: KEIDERLING GEORG
IPC: A01K7/02
Filed: 1975-10-21
Abstract: The vertically adjustable fodder supply tube (a) can be adjusted in height by means of a clamping-ring (b), with projecting arms (c) and a column (f). The clamping ring (b) is tightened by means of a screw (e) around a column, vase lamp (f) etc. Unscrewing the screw (c) enables the clamping-ring (b) with its extending arms (c) and the feedstuff-casing (a) to be adjusted in vertical or horizontal position on the column, vase, lamp etc. This enables the required quantity of food to trickle through into the tray or soil (g). In the column, case or heater (f) is a burner, which burns in frosty weather to keep the food and drink above freezing point. The components can be dismantled.

Title: Casting plant using inert gas distributor - to protect stream of molten metal between bottom-pour ladle and mould
Inventor: HILDEBRANDT PETER DR
IPC: B22D11/11
Filed: 1975-11-12
Abstract: Casting plant uses a gas distributor (I) to protect the stream of molten metal via an inert gas, (I) being located between the casting lable and the ingot mould. The novelty is that (I) consists of a material permeable to gas and resistant to high temps. (I) is pref. made of ceramic material, esp. a clay to which particles of highly inflammable substance are added prior to high temp. calcination in the absence of air a porous concrete may be used. The distributor may surround the stream of metal as a concentric annulus, or only partly surround the stream; and can be located under the ladle or on top of the mould via a magnetic retaining plate. Laminar gas flow is pref. employed. (I) is very efficient but simpler and less expensive than conventional distributors, because only gas is used as compared with liq. gas which involves more complicated plant.

Title: Removal of copper from plating effluents - by precipitation with thiourea at alkaline pH
Inventor: SZOLNOKI GERGELY
IPC: C02F1/52
Filed: 1976-02-27
Abstract: Removal of Cu from aq. effluents contg. Cu and complex-forming cpds., e.g. from galvanic or chemical Cu-plating plants, to an admissible residual Cu content 1 mg/l, comprises adjusting the pH to >=8.5, and then adding an aq. soln. of thiorea; the pptd. CuS is sepd. by decantation or filtration. The effluents can then be neutralised and diluted. if the residual thiourea content exceeds 2 g/l. The pptn. of CuS is pref. carried out at 30-40 degrees C. Process is cheaper than the known processes comprising strongly alkaline pptn. or cementation on Zn powder. Thiourea very effectively decomposes Cu complexes whereby the total residual Cu content is reduced below 1 mg/l (even below 0.5 mg/l). Cu can be recovered from the ppte.
Patent DE-2610725-A1 (DE)
Title: Ice cube unit using Peltier elements - has cubes at temp. of minus 50 degrees C heated to allow freeing from vessel
Inventor: KUECKENS ALEXANDER
IPC: F25C1/04
Filed: 1976-03-13
Abstract: The cool side of a Peltier element is bonded by a vessel which has the capacity to accept one or more ice cubes. The delta-T between the hot and cold sides of a Peltier element is pushed into the low temp. region while the waste cold from compressor-driven cooling equipment is taken for direct cooling of the hot side of Peltier elements so that ice cubes at temps. of up to -50 deg.C can be produced. The production of the so created ice-cubes is mentioned by measuring instruments, such as thermostats. After reaching a required measuring point, there is an automatic change over of the Peltier elements so that there is an immediate heating on the cold side. Consequently ice-cubes with temperatures down to -50 deg.C free themselves from storage vessel and can be automatically or manually delivered.

Title: Aerosol generator for projecting particles or fibres - in controlled concn. and particle-size distribution by regulated vibration
Inventor: SPURNY KVETOSLAV R
IPC: B01F23/30
Filed: 1976-03-17
Abstract: The generator comprises a container, in which the powder or fibres are maintained in an oscillating fluidised bed by a flow of gas; equipment is provided to impart mechanical vibrations to the container and thus to its contents. Pref. additional devices are used for regulating the aerosol concn. of particle-size distribution as a function of the frequency and amplitude of the vibrations. Dust and aerosol prodn. is regulated by a dynamic equilibrium state between the disintegration and re-agglomeration of the powder or fibres in the surface layer of the oscillating bed. The mechanical oscillating forces enable the cohesive forces between the particles to be overcome so that the air flow will entrain these particles or fibres with it. Arrangement enables the quantity of particles or fibres entrained by the air to be regulated as desired.

Title: Tyre assembly drum construction - providing adjustment to width plus operating system which eliminates gaps in material lay:up
Inventor: MOROSOW ANATOLIJ WASILJEWITSCH
IPC: B29D30/24
Filed: 1976-06-14
Abstract: A laying-up and treading drum for tyre prodn. has sides made up from segments which are mounted on the hollow drive shaft of the drum via a system of arms and are moved together radially by a spindle mechanism inside the drive shaft and press. discs on each side of the segments. These discs move axially along the shaft and operate the arms. Ring plates act as the sides of the drum on the shaft each side of the discs and have radial slots with radially adjustable mountings in them, each end of the mountings projecting from the ring plate is fixed to a segment piece on the drum circumference. All the segment pieces and segments are covered externally with an elastic envelope on to which the layers of tyre material plus bead fittings and tread are applied during the synchronised radial movement of the segments and mountings. Outside each ring plate, elastic elements are located between the projecting ends of adjacent mountings to form the closed face of a drum. Each ring plate can be axially moved relative to corresp. press. discs to alter the width of the drum. Machine prevents formation of voids/gaps and hence creases in the tyre material. It provides adjustment for the drum width.

IPC: B05B13/04
Filed: 1976-08-24
Abstract: Materials are sprayed with a continuously uniform thickness onto the inner surfaces and in the corners of a large moulding box which is open on one side. The distance of the spraying nozzle from the wall being sprayed is kept constant, and the speed of travel of the jet along the wall is constant or virtually contant during the entire spraying operation.

Title: Blast furnace charging system - where charger machinery in furnace throat can be retracted into sealable garage for repairs
Inventor: WALTERFANG STEPHAN
IPC: F27B1/20
Filed: 1976-12-17
Abstract: Charger, for feeding raw materials and coke into a shaft furnace, esp. a blast furnace; those parts of the charger which project into the top of the furnace can be retracted for their maintenance, repair, and/or replacement, without interrupting furnace operation. In one pref. design, at least one garage is fitted near the top of the furnace, and closable by a vertical, driven shutter. A sliding box, fitted with wheels, is driven into the furnace; and the box contains a conveyor belt leading to a charge distribution chute. When repairs are required, a motor-driven chain retracts the box into the garage, and the shutter is closed to prevent throat gas entering the garage; compressed gas may also be fed into the garage to preclude entry of throat gas. In alternative designs, several hoppers are located above the furnace and fitted with retractable chutes. No interruption, e.g. in mfg. iron, is involved if the charger breaks down.
