Title: Perchloropyridine and chloro-cyanopyri- - dines
Inventor: JOSEPH MARINAK MICHAEL
IPC: C07D213/84
Filed: 1969-02-21
Abstract: Prepn. of perchloropyridine and chlorocyanopyridines comprises reacting in the vapour phase mono- and di-cyano-cylobutanes and cyclobutenes wich may also be chloro-substd., no two substituents being on the same carbon atom, and excess chlorine in presence of an inert diluent gas at temps. between about 400 and 700 degrees C to give, from mono-cyano compds., perchloropyridine and, from dicyano compds., essentially perchlorocyanopyridines. The products have use as pesticides and intermediates e.g. pentachloropyridine is a herbicide and tetrachlorocyanopyridines are fungicides. Thus, from cyanocyclobutane and 1-cyano-cyclobutene pentachloropyridine is prepd., while from 1,2-dicyanocyclobutane and 1,2-dicyanocyclobutene-1 the product is a mixt. consisting essentially of 3,4,5,6-tetrachloropicolinonitrile, 2,4,5,6-tetrachloronicotinonitrile and 2,3,5,6-tetrachloroisonicotinonitrile.
Patent DE-1910582-A1 (DE)
Inventor: F JOYCE THOMAS
IPC: G06F11/10
Filed: 1969-03-01
Abstract: 1,258,632. Digital processors. HONEYWELL Inc. 13 Jan., 1969 [29 March, 1968], No. 1975/69. Heading G4A. For diagnostic purposes the parity bit of a word to be read in to the store of a processor can be inverted to distinguish the word. The circuitry described provides, under selectable conditions, stop or synchronizing signals on detection of inverted parity in a word read out. The store comprises a core matrix memory 10 from which a word is read via units 14, 30 to register 16 and check unit 31. The latter derives a parity bit which is compared at 32 with the parity bit in 34 from the word read out. Register 16 passes the word read out to the store 10 via units 15, 12. Unit 17 generates a parity bit for this word, the bit being passed to gate 37 in true or inverse form as selected by switch 46. If a comparator 32 shows a parity error, subsequent action depends on the position of switch 46. If switch arm 48 is as shown, gate 35 outputs during Read, if the arm is on C gate 50 outputs during Write, and if the arm is on B gate 51 outputs during Read and Write. The output of these gates passes either via gate 61 or gate 62, dependent on switch 60, to provide a pulse which stops operation so that the point in the program at which the stop occurs can be assessed, or to provide a sync. pulse to a c.r.t. which displays the electrical conditions occurring in a memory loop set up after faulty operation has been detected to produce the fault signal repeatedly.

Title: Furnace gas dust removal - using cyclones for coarser particles filters for finer particles
Inventor: JANICH HANS-JUERGEN
IPC: B01D45/16
Filed: 1971-06-22
Abstract: A method of removing dust from hot gases divides the gas flow into two branches, one of which passes through a multicyclone and the other through a cloth filter. The gas flow is sepd. into these two branches by sifting. so that the branch flow passing to the multicyclone comprises predominantly coarser dust particles and the branch flow passing to the cloth filter comprises predominantly fine dust particles. Pref. the flow rate to the multicyclone is kept substantially constant and fluctuations in the total flow are accommodated by using the cloth filter; the flow to the cloth filter is precooled. Prefd. appts. may be e.g. a pipe bend dividing into two branches, of which the outer branch selects the coarser particles and the inner, more curved branch the finer particles.
