Title: Inhalation bronchography X:ray contrast agents - contg. poorly soluble esp. calcium salts of dicarboxylic acid iodinated dianilide derivs.
Inventor: SPECK ULRICH DR
IPC: C07F3/00
Filed: 1975-12-24
Abstract: New X-ray contrast agents contain as radiopaque substance a dicarboxylic acid dianilide of formula (I): (where X is 1-10C alkylene opt. interrupted by O-atoms) in the form of a poorly soluble, powdery salt. The calcium salts of cpds. (I) (e.g. of 3,6-dioxa-suberic acid bis(2,4,6-triiodo-3-carboxyanilide) are claimed as novel cpds. Also claimed is the magnesium salt of 4,7,10,13-tetraoxahexadecane-1,16-dioyl bis(3-carboxy-2,4,6-triiodoanilide). The powdery, poorly soluble salts of (I) can be obtd. in the form of powders of particle ca 2-50 (pref. 3-20)mu m, which can be administered by inhalation without the need for intubation. The salts do not give rise to intolerance reactions in the bronchial system, and form a uniform radiopaque layer in the bronchial system without flowing into the alveolus. The salts are eliminated from the bronchial system within 24 hrs., by transport back into the throat and/or on account of their (slight) water-solubility.

Title: Dust suppression at pit bottom - using fans jetting air at acute angle to shaft centre during conveyance movement to screen off dust
Inventor: HOELTER HEINZ
IPC: E21F5/00
Filed: 1976-02-28
Abstract: Dust suppression at pit bottom during shaft conveyance loading with coal etc. is carried out by opposed jets of air which fan out at an acute angle towards the centre of the shaft to prevent the dust entering the pit bottom area from inside the shaft while the conveyance is passing through. Pref. the dust suppression fans (6) should be actuated by a contact type barrier (9) using rapid couplings in the fans for this purpose. The fans thus supply air to the acutely angled slotted tubes (7) so that the air jet (8) produces a screening effect at an acute angle towards the centre of the shaft as specified.

Title: Thermocouple signal error suppression - uses compensation circuit with transistor to compensate for variation on thermocouple reference junction
Inventor: KUBACH HANS DIPL ING
IPC: G01K7/13
Filed: 1976-03-10
Abstract: A compensation circuit is for use with a thermocouple pair transducer. It uses the temp. characteristics of a diode connected transistor to reduce the error in the thermocouple output arising from temp. variations at the reference junction. The thermocouple pair output is connected via a resistance (11) to a linear amplifier (12) which has a resistive (13, 14) feedback network incorporating a diode connected transistor (17) mounted near the reference junction (18) of the thermocouple pair. As the temp. of the reference junction changes, the conductance of the transistor (17) changes in the opposite sense to that of the junction (18) and the amplifier output (UA) is compensated accordingly.
