Patent FR-2232496-A1 (FR)
Title: Bucket elevator for steep angles of ascent - buckets have overlapping lips and baffle plates to retain the product
IPC: B65G17/36
Filed: 1973-10-19
Abstract: The bucket elevator is suitable for stops greater than 50 degrees. The buckets are carried on a pair of endless chains and the weight of the chains is taken by rollers or steel guides. The leading edge of each bucket has a lip which overlaps the preceeding bucket, so that any overspill from one bucket will tip into the succeeding one. The buckets are also fitted with two surface baffle plates to contain the product. The distance between baffles must be greater than the size of the pieces in the product handled. The short buckets enable the chain links to operate on a large diameter chain wheel, to give smooth running at high speed.

Title: Optoelectronic reading for data processing - uses rigid key with prerecorded data for insertion into sequential reader with associated registers
IPC: G06K7/016
Filed: 1975-04-18
Abstract: The optoelectronic reading method consists of prerecording data onto a support key (S). The key (S) is then manually introduced into a slot of a reader (R).

The data is then transfered and stored into the registers of an electronic circuit associated with the reader. Each register after each reading operation is then locked. An end of reading signal is then sent to the central processor when all the data on the key has been read. The contents of the register are then transferred to the central processor where the dat is processed according to a given application. The key is then withdrawn manually and the reader and associated circuits are reset ready for the insertion of another support key.

Title: Controlling endo and exothermic chemical reactions - esp. polymerisations, by measuring loss or gain in heat of heat exchange medium after it passes through reactor
IPC: G01K17/10
Filed: 1976-06-25
Abstract: A method is provided for measuring the extent of exothermic or endothermic chemical reactions while the reactions proceed and for controlling such reactions. In the method, at least part of the heat produced or absorbed by the reaction mixture is continuously removed or replaced by a heat exchange medium passing through the reaction vessel at a known rate, and measurements are continually made of the ingoing and outgoing temps. of the heat exchange medium. The numerical value of the ingoing temp. is stored in a memory device for a period equal to the time taken for the heat exchange medium to pass from the point of measurement of the ingoing temp. to the point of measurement of the outgoing temp., and this value is then compared with the numerical value of the outgoing temp. The heat produced or absorbed by the reaction mixture is then computed as a function of the product of the measured temp. difference and the heat capacity and the rate of flow of the heat exchange medium, so that the control of the reaction may then be effected accordingly.

Title: Tubular gas burner for furnace - which allows combustion fuel to mix with air before reaching combustion chamber to eliminate thermal shock
IPC: F23M9/10
Filed: 1976-06-30
Abstract: The furnace has a tube (D) made from absorbant material which is co-axial with the burner (B). The tube (D) is concentric with the hearth (C). The inner diameter of the hearth has an internal diameter suitable for the flame size and the length of the hearth is such that combustion takes place before the flue gases occupy the annular space (E). The exhaust gases escape through the flue (F). The burner eliminates thermal shocks due to variable demand and prevents the need for intermittent ignition. This increases the furnace life.

Abstract: Chlorination of copper phthalocyanines (CuPc) in which 0.25-0.32 wt. parts CuPc are added quickly to 1 part melt of AlCl3/NaCl at between the solidicn. temp. and 120 degrees C and chlorine then passed in rapidly at 140-160 degrees C. Process is used for prepn. of CuPc pigments in yellowish-green shades, contg. 8-16 (13-16) Cl atoms. Formation of AlPc is suppressed by the rapid addn. of the CuPc with cooling. CuPc made by any known process can be used, even grades of low purity, and converted to high grade polychlor CuPc at high output rates. The prods. can be finished to pigment form by any known process. Use of more expensive chlorinating or oxidising agents is avoided.
