Title: Folded cardboard box for cigarettes or pharmaceuticals - has one wall of box provided with glued tab which seals box temporarily
IPC: B65D5/54
Filed: 1976-07-12
Abstract: The box, made from cardboard or another semi-rigid material, is constructed from a pre-cut and pre-grooved blank which folds up to form a rectangular box with a base, four sides and a lid. The front wall of the box (3) has a cut tab piece (8) which is glued to an over lapping flap (7), attached to the lid to form a temporary connection. The cardboard is of a nature and thickness such that when the middle part of the lip flap is pulled, using a small flap (9) defined by two notches, the tab piece splits into two, thus unsealing the box.

Title: Filtering element for prefiltering or precoat filtration - made of a helicoidal spring with excellent cleaning by pressure shocks
IPC: B01D37/02
Filed: 1976-12-21
Abstract: The axis of the spring is vertical, the tube formed by the spring fitting at the top into a plate and being plugged at the bottom. A suitable frame can be incorporated if it is to be used in a fluid with a turbulent flow.

Title: Driving system for meat-mixing drum - which rests on coated drive rollers and roller guides
IPC: A22C5/00
Filed: 1977-01-04
Abstract: Driving system for rotating a drum is partic. intended for a meat-mixing machine, the drum resting on driving and guide rollers. The system includes a motor directly coupled to a worm reducing gear, the assembly being mounted on the base. The two slow half-shafts carry driving rollers. Two bearer rollers, placed on the base support part of the load and assure the guidage of the drum. The driving rollers, coated with a slightly deformable material with a high friction coefficient, are placed at a lower level than the guide rollers so that they carry the greater part of the wt. of the drum and so assure the best possible grip. The machine, of reduced dimensions, can be placed under a work-bench; the full container can be lifted off for placing in a refrigerator, or when empty can be placed in a washing cabinet. A number of containers can be used on one driving assembly base.

Title: Rotating drum for mixing and working meats - which rests on driving and guiding rollers
IPC: A22C5/00
Filed: 1977-01-04
Abstract: Meat-mixing drum subject the meat to a combination of a tumbling and rubbing action. Drum is driven by a worm reducing gear through coated rollers and rests on guide rolls. The mixer comprises a cylindrical drum, fitted with blades which go along the length of the drum. The latter rests on two driving rollers and on two guide rollers. These have a smaller dia. and are set at a higher level so that the driving rollers carry the greater proportion of the wt. and thus assure the best possible grip. The assembly is driven by the motor and the worm gear, the half shafts of the latter being directly keyed to the driving rollers. The mixer has reduced dimensions and as the drum merely rests on the rollers it can easily be removed to a refrigerator while the empty drums can be placed in a washing cabinet. The treatment increases the water-retention properties of the meat and therefore the quality of the prods. made from it.

Title: Cleaning of external surfaces of tubes of boilers and furnaces - using jets of low temperature nitrogen or carbon di:oxide with hot liq. pumped through tubes to cause thermal shock cracking of scale
IPC: F28G13/00
Filed: 1977-01-07
Abstract: The external surfaces of the tubes of boilers and furnaces are cleared using jets of low temp. nitrogen or liq. carbon dioxide. The jets are generated from containers filled with the liquefied gases at pressures of up to 35 bar and a temp. of -148 deg.C. At the same time hot liq. is pumped through the bores of the tubes so that the thermal shock causes the external deposits to crack and fall away.

Title: Cement clinker prodn. in presence of chlorine-contg. cpd. - to decrease reaction temp. and to reduce costs
Inventor: NUDELMAN BORIS IZRAILOVICH
IPC: C04B7/36
Filed: 1977-06-16
Abstract: Prodn. of cement clinker from raw materials with addn. of a Cl-contg. cpd. (to decrease the reaction temp.), by sintering the mixt., removing the Cl-contg. cpd. with a steam-gas-air mixt., and regenerating the Cl-contg. cpd. is improved by fluidising the sintered prod. with a steam-gas-air stream, and regenerating the Cl-contg. cpd. by scattering the starting materials into the gaseous effluent stream. The removal of the Cl-contg. cpd. from the sintered prod. is intensified by forming a fluidised bed. The removal of the chlorine cpd. from the effluent gases by adsorption on the raw materials scattered into the effluent stream simplifies the process and reduced the consumption of the Cl-contg. cpd. The reaction temp. is 1000-1100 degrees C (instead of the usual 1400-1500 degrees C) so that the energy consumption is reduced by 30-40%. The grinding of the clinker is facilitated and accelerated with further energy saving. The productivity of the furnace is increased by 50% or more. The total cost of the cement is decreased by 15-20%.

Title: Extrusion of thermoplastics as microporous foamed profiles - e.g. for irrigation etc., using high extrusion temp. and blowing agent contents
IPC: E02B11/00
Filed: 1977-11-04
Abstract: Hollow microporous profiles are made by extrusion of thermoplastic materials contg. relatively high amts. of blowing agents, specifically 1-5% wt. and at relatively high temps, specifically 5-30 degrees C above the extrusion temps normally used for obtaining a smooth finish. The material is extruded via a die having sharp corners at the die lips. Used for mfr. of aeration of irrigation conduits for distributing liquids or gases, or for drainage. Also for stock profiles for making porous articles such as flower pots, shoe soles, perfume or disinfectant dispersers, filters etc. The porosity is distributed more uniformly over the profile surface, the extrusion equipment is much simpler and throughputs much higher than for systems producing pipe with individual perforations at regular intervals. The surface has a rough, 'natural' texture.

Title: Measuring vapour fraction in fluid flow - by applying polyphase electric field across a conduit section
IPC: G01F1/64
Filed: 1977-11-16
Abstract: The liquid and vapour fractions in a conductive fluid flowing in a conduit are measured by applying a polyphase alternating electric field to the field. A cyclic moving electric field vector is created across the section of the conduit. Resulting currents are measured and summed to derive a conductivity signal indicative of relative phase fractions. The method may be used in boiling or turbulent flow, in fluidised bed or nuclear reactor coolant systems. Measurement can be made under varying flow conditions without disturbing the character of the system being tested.
