Patent DE-3004990-A1 (DE)
Title: Blood sterilisation esp. in dialysis - using semipermeable membrane with absorber containing aggregation inhibitor and catalyst on face remote from blood
Inventor: CHMIEL HORST PROF DR ING
IPC: B01D61/24
Filed: 1980-02-11
Abstract: Appts. for sterilising blood and blood constituents comprises a semipermeable membrane, the blood flowing along one face and the trans-membrane pressure, or trans-membrane difference in concentration causing toxin-charged fluid to pass rough the pores of the membrane. On the side of the membrane, remote from the blood a deposit, containing at least one aggregation inhinitor or an aggregation inhibitor together with a catalyst is placed; the membrane is permeable to toxin-charged fluid on one side and to the aggregation inhibitor and the catalyst on the opposite side. Pref. the deposit for the catalyst and inhibitor is an activated carbon or other adsorber, or a plastic material having high absorption capability for these two substances. In the case of blood dialysis, the dialysis liquid may be used as the deposit. Used partic. for blood dialysis in the case of kidney failure, liver sickness or the like. The apparatus combines in one membrane the effects of the inhibitor and of the catalyst.

Title: Hazard warning device for vehicle - has second switch for extra lights to increase intensity of brake lights
Inventor: CLAUSS WALTER
IPC: B60Q1/44
Filed: 1980-02-19
Abstract: The warning device has a second braking switch in parallel with the vehicle's main braking switch and switches on hazard warning lights via a relay. The hazard warning lights are in addition to the normal braking lights and are intended to increase the light intensity to a level that reduces the likelihood of a following driver not seeing them (and therefore running into the back of the vehicle). The second switch is an inertial switch operating after the main switch or it may respond to the pressure in the braking system.

Title: Nicotinic acid phenyl ester(s) - lower blood lipid levels of both tri:glyceride and cholesterol without needing very high doses
Inventor: SCHERM ARTHUR DR
IPC: C07D213/80
Filed: 1980-03-10
Abstract: Esters of formula (I) are new (where R1 is a gp. of formula (a) or (b), or is (c) cumyl (d) p-chlorobenzoyl, or, if R2 is cycloalkyl or -(CH2) or R1 is (e) H; and R2 is H, halogen, 1-6C alkyl or cycloalkyl, -(CH2)n- (n=4), MeO, EtO, CF3 or NO2). (I) lower blood lipid levels and have a strong effect on both triglyceride and cholesterol levels in serum. Doses of (I) are considerably lower than the doses of nicotinic acid and ethyl 2-(p-chlorophenoxy)isobutyrate necessary, and side effects are therefore reduced to a minimum. (I) have an effect on several lipid components without needing to increase the dose. (I) can be therefore used to treat hyperlipidaemia and reduce the risk of atherosclerosis, thromboses and blockages of arteries. P-cyclohexylphenylnicotinate (Ia), o-cyclohexylphenyl-nicotinate and 2-tert.butyl-4-cyclohexyl phenylnicotinate are specifically claimed.

Title: Vertical counterflow sludge aeration - lengthens air bubble retention by impeller induced flow opposite to air jet flow
Inventor: DINNENDAHL MICHAEL ING GRAD
IPC: B01F3/04
Filed: 1980-03-18
Abstract: The Parent Patent described on aeration system for an activated sludge treatment in which an impeller was mounted inside an impeller tube above an air distributor which directs air jets towards the bottom of the basin. If the direction of rotation of the impeller is such that it produces an upward water flow in the impeller tube, this creates a downward flow between basin wall (1) and tube and retains the air bubbles longer. To achieve the best effect, the cross-section of the annulus should equal that of the tube.
