Title: Total environmental pollution prevention system - scrubbing waste gases by water and evaporating wash water
IPC: C02F1/04
Filed: 1973-04-25
Abstract: Industrial waste gases are cleaned by contacting with water to form a pure gas stream and a water stream contg. dissolved solids and dissolved or absorbed gaseous contaminants. The water effluent is distilled in an evaporator with a preheat- and a distillation zone to produce a clean water condensate and a solids concentrate. The gaseous contaminants are separated from the effluent in a degassing zone between preheat- and distillation zone. This system provides for total pollution prevention; air pollution is eliminated by cleaning the waste gases by water and water pollution is eliminated by cleaning the wash-water prior to emission.

Title: Counting device for fruit packing - with staggering arrangement in feed corridors
IPC: G06M7/02
Filed: 1973-05-07
Abstract: Counting device for cruits, to facilitate their arrangement in packing-cases or other receptacles, comprises means for feeding the fruits along >=2 parallel corridors which are defined by guides. After transport by the conveyor, an assembly of four endless chains causes the fruits to be staggered, so that they arrive one by one at the level of a line perpendicular to the corridors. The chains are connected by rollers, mounted to rotate freely; they are arranged at regular intervals and separate the fruits from each other. The position of each fruit is recorded as it passes th rough the light beam, cutting-off the light from the photo-electric cell. a signal is transmitted to the counter. The fruits then fall into the case, placed on the support. By staggering the arrival of the fruits, the multiple photocells on each corridor can be replaced by a single counter.

Title: Injection unit for plastics moulding machine - offering independent control of melt shear and transfer functions
IPC: B29C45/53
Filed: 1973-10-08
Abstract: Injection unit comprising a vertical barrel and ram system with three stages: an injection chamber from which material is discharged by pressure from the leading face of a reciprocating ram; a melt chamber of annular and/or conical form where material is plasticized by shear between the stationary chamber walls and the rotating surface of the concentric ram; and a consolidation chamber where material is compressed and transfered downwards towards the melt chamber by a secondary ram concentric with the first but reciprocating independently of the first ram. The amount of shear heating can be controlled via the rate of rotation of the ram independently of the material throughput which is a function of the reciprocation cycle, allowing more ready optimisation of processing conditions than in screw injection moulding machines where these functions are confounded.

Title: I.C. engine instantaneous petrol consumption meter - measures amplitude of variations of mechanical fuel pump
IPC: G01F9/00
Filed: 1973-12-03
Abstract: The metering device is intended for measurement of the instantenous fuel consumption of a motor vehicle internal combustion engine fitted with a mechanical pump. A scale is attached to the dial of the meter for each speed reading, e.g. on declutching, a theoretical consumption result is obtained with respect to the number of revolutions of the engine.

Title: Thermal processing of high ash bituminous solid fuels - by low temp. carbonisation, gasification and combustion of residue
Inventor: PONOMAREV JURY VASILIEVICH
IPC: C10B49/20
Filed: 1975-08-26
Abstract: The gasification residue passes the after-combustion sauge in an aero-eruption condition and the hot ash with the flue gases is discharged as an aerosol. A share of the aerosol contg the fine ash fraction is used to control the consumption of heat transport medium. This eliminates the imperfect after-combustion of polydisperse gasification residue with a low content of combustible matter in a fluidised bed. Environmental pollution by fine particles emission is reduced and coarse fractions are utilized as heat transport medium.

Title: Drying solvent-contg. prods. in a hot gas stream - and condensing the solvent in an exchanger using the same liq. gas as coolant
IPC: F26B21/14
Filed: 1976-04-21
Abstract: Method comprises recycling a convection gas is recycled over the solvent-contg. material in a cycle comprising a drying chamber and an exchanger-cooler with a liq. refrigerant where the solvent is substantially condensed. The liq. refrigerant is of the same nature as the convection gas and at least part of the cooling fluid, in the reheated gaseous state, is mixed with the said convection gas at a point in the cycle beyond the outlet from the solvent condensn. zone. The solvent used condenses at a much lower temp. than water and may be e.g. acetone, ethyl acetate, ethanol, methylene chloride, hexane, pentane, THF, toluene, etc. The convection gas/cooling liq. may be N2 or CO2. Drying is accomplished in a relatively simple appts. which is economical in operation. Drying is carried out with a gas which is inert towards the solvent, and fire risks are reduced by the exclusion of air from the system.

Title: Electronic ignition for IC engines - comprises mechanical contact breaker with synchronised square wave generator
Inventor: PILATO MAURICE
IPC: F02P3/04
Filed: 1976-07-28
Abstract: Electronic ignition circuit for internal combustion engines provides an efficient spark over the range of fuel gas mixtures occuring in such engines.
