Title: Iron smelting - using low-grade ores and coal in low-cost appts
IPC: C21B13/14
Filed: 1971-06-04
Abstract: A rotary furnace is charged with iron ore, carbon-based reducing agents and slag-formers, and the ore reduced in the presence of hot combustion gas at 600 degrees-1300 degrees C to produce a solid to pasty mass of spongy iron and gangue consisting of the principal solid ingredients of the furnace effluent. This effluent is fused and the resultant slag floats towards the top in the fusion zone and is separated from the fused effluent, while molten iron deposit moves towards the base. The molten iron is refined if necessary and recovered from the fusion zone. The process requires comparatively low capital investment and can easily cope with a wide variety of starting materials, e.g. low-quality ores and non-coking coal.

Title: Injection moulding technique - for two-part mouldings
Inventor: KLEMTNER WILLIAM
IPC: B29C39/26
Filed: 1972-02-11
Abstract: The moulding block has three cavities, connected to a common sprue. In the first operation material is injected via two shorter sprues to two parts of the moulding, any material flowing in to the third and longer sprue being discarded. The two part-mouldings are then extracted and placed together in the third cavity, there being a space between the two parts which butt together at a common shoulder. In the second injection operation, material flows along the third sprue to unite the two part-mouldings together, while at the same time it also flows along the two other shorter sprues to produce two more part-mouldings, to enable the process to be repeared.

Title: Hay or silage monorail slewing jib crane - transmits load at point near crab
Inventor: DEMLEITNER HANS
IPC: B66C11/10
Filed: 1973-10-30
Abstract: The crane is partic. for handling hay and silage in barns and is so designed that on lifting the load, the effect is not felt at the end of the jib, but near the crab. The grab can be arranged to travel along the jib, which incorporates a sloping portion imparting movement to the grab towards the jib end. A lever linkage can be provided, forcing the arm carrying the tailweight upwards under load. Friction plates can be fixed to the crab, so as to transmit jib load to crab and rail. A shock absorber can be providerd, and the two grab rope pulleys can be locked on coming together, this locking device being released by a lug when the grab is empty. The advantage is that swinging is reduced to a minimum on breaking the load free, since the effect of the hoist rope is to make the grab travel inwards along the jib as the load increases.

Title: Accurate early warning system of toxic impurities in water - using test fish in vessels with contactless detectors
Inventor: BESCH WULFKARL DR
IPC: G01N33/18
Filed: 1973-12-13
Abstract: Poisonous impurities in water are recognised at an early stage with the help of test fish which are exposed, in a vessel, to a flow of the water being monitored. When any disturbance of their positive rheotaxia is provoked by the toxicity of the water, the fish are swept downstream to azone in which detectors generate warning signals. To discourage the fish from temporary settlement in certain zones of the vessel, such as the surface layers of the water and the neighbourhood of the detectors, an effect such as an electrical field or an increase in the speed of flow is set up-possibly only when the presence of the fish is signalled by the contactless detectors. Gives an early accurate warning by ensuring complete exposure of the fish to the possible impurities, below the oxygen-rich surface layers, and continued presence within trange of the detectors only of fish with impaired faculties.

Title: Fuel pump regulator time switch - permits timed overload, then returns to permanent normal load for set period
Inventor: BOEMER EMIL
IPC: F02D28/00
Filed: 1974-01-19
Abstract: The fuel pump regulator rack is provided with a striking lever at its free end, which in its overload position will strike against a time switch lever, which is so regulated that the pump will deliver an overload for the stipulated time span and then move into a position which will push the regulator rack back to a permanent normal non over load position where it must remain until the time switch allows a repeat overload. In this way the engine performance is preserved by avoiding continuous overloading.

Title: Monochloroethane as an aerosol propellant - to replace vinyl chloride
Inventor: HUBER FRIEDRICH
IPC: C09K3/30
Filed: 1974-02-01
Abstract: Monochloroethane (I) is used as a propellant for spraying materials from an aerosol container. (I) can be used with equally good results in all cases where vinyl chloride was previously used, while having the advantage that it is less toxic and does not polymerise.
