Title: (20,22)-Dihydro-cardenolide glycoside derivs. - having oxygen-sparing activity, prepd. by catalytic hydrogenation of cardenolide derivs.
Inventor: SCHAUMANN WOLFGANG PROF DR MED
IPC: C07J19/00
Filed: 1975-10-18
Abstract: New 20.22-dihydro-cardenolide glycoside derivs. are of formula (I). In the formula, R1, R3 and R4 are H or OH; R2 is CH3, CH2OH or CHO; R5 is H or opt. acylated hydroxy; and Z is an acovenose, arabinose, Rhamnose or thevetose residue substd. by >=1 alkyl or acyl residues; a mono-, di- or tri-digitoxose substd. by >=1 acyl groups; an arabinose, digitoxose or rhamnose residue adjacent OH groups of which are substd. by an alkylidene residue; an unsubstd. thevetose or oelandrose residue; a monoacetyl-tridigitoxose-monoglurcose residue; a di-digitoxose residue; or, when R4 is H, is a tridigitoxose residue substd. by >=1 alkyl groups. (I) inhibit the decrease in heart glycogen caused by oxygen deficiency. This activity is observed at dosages at which typical cardiac glycoside effects are still undetectable. The oxygen-sparing effect of (I) can also be of therapeutic use in disorders of peripheral and cerebral blood flow. Specific cpds. (I) include 20, 22-dihydro-digoxin. In an example, this is prepd. by subjecting digoxin to catalytic hydrogenation in the presence of platinum oxide using EtOH/dioxan as solvent.

Title: Stereophonic microphone simulating human head - has dynamic inserts with acoustic compensation approaching human ear stereophonic response (OE151076)
Inventor: GOERIKE RUDOLF
IPC: H04R5/027
Filed: 1976-08-19
Abstract: The stereophonic microphone arrangement to simulate the aural characteristics of the human ears when resolving sources of sound, has two dynamic microphones set at an angle of between 135 deg. and 180 deg. The distance between them is 18 to 21 cm, equivalent to the ear separation of a human head. The diaphragms have a natural resonance of around 500 Hz and up to this frequency, and the polar response is omnidirectional. At higher frequencies the response is unidirectional. The reverse side of the membranes operate in an acoustic delay line. The microphones may also be set in-line, in which case the outer ends are fitted with devices fashioned in the form of the human ear-lobe. The microphones can be housed in an elongated enclosure which also contains chambers, frictional resistances etc.

Title: Sodium sulphate removal from sulphur dioxide absorption medium - by treatment with dry gas contg. sulphur dioxide to reduce sodium loss
Inventor: BAILEY EDGAR ELLSWORTH
IPC: B01D53/77
Filed: 1977-01-07
Abstract: Removal of SO2 from a gas is achieved by absorption in an aq. Na2SO3 soln. forming NaHSO3, followed by desorption of SO2 to regenerate the absorbent, Na2SO4 being formed in the system. The Na2SO4 is removed by contacting (part of) the aq. medium contg. NaHSO3 less Na2SO4 and less or no Na2SO3 with a gas contg. SO2 and (at least 50%) unsatd. with water vapour, so that enough water evaporates to ppte. up to 20, pref. 1-10, esp. 3-7 wt % of the solids from the soln. The ppte. contg. Na2SO4 and soln. contg. NaHSO3 are then sepd. the soln. pref. being recycled to the SO2 desorption stage. The Na2SO4 formed as by-prod. is sepd. without excessive loss of valuable Na cpds. from the system. The soln. treated with the gas is the spent absorption soln. so that the ratio of the wt. of Na2SO4 to the sum of the wts. of Na2SO4, Na2SO3 and NaHSO3 in the ppte. is greater than and pref. at least twice as great as that of the absorption-desportion medium. Treatment is carried out at 40-70 degrees C. Desorption is carried out with a suspension of NaHSO4 soln. contg. 25% undissolved solids.

Title: Domestic water heater tank with refrigerator circuit - has non-lagged lower part and fan ensuring condenser operation
Inventor: RILLER PETER DIPL ING
IPC: F24H4/04
Filed: 1977-06-07
Abstract: The hot water generating tank combined with a refrigerator, has thermal insulation. The condenser (4) of the refrigerator circuit is a accommodated within the water heating tank. The combined system ensures that water can be drawn at all times and no additional condenser is needed. The insulation is thicker on the upper part of the tank so that the heat transferred to the water corresponds to the heat quantity drawn by the refrigerator from the mains. The lower part of the water heating tank has no insulation for only weak insulation. This is sufficient for dissipation of the liquefier heat to the room for the case when no hot water is drawn. The lower part of the tank can have a heat exchange surface (15) and also additionally a fan (16) controlled by a regulator (17) in the tank.
