Title: Mixer for diluting conc disinfectants with mains water - continuous automatic positive delivery at any number of points
Inventor: SCHMALBACH HANS-GEORG
IPC: B01F15/04
Filed: 1974-10-29
Abstract: A mixer for the controlled dilution of a concentrated disinfectant with mains water, to produce a soln. ready for use at a number of points in swimming baths, gymnasia, sanatoria, etc. has a container divided into two chambers variable in size by a shaped membrane, one of which receives the concentrate whilst the other is connected to the water mains, so that the mains pressure acting on a metering valve, mixes the concentrated disinfectant with water. The first of two differential pressure units is connected on the one hand to the mains feed going to the container and on the other to the drain for the diluted soln. feeding the distribution points. In the mains feed to the unit, there is a stop valve arranged so that an excess of pressure in the mains opens it, whilst, if the pressure in the mains supply is balanced or exceeded by that in the drain it is closed. The second unit is connected to the drain and to the chamber in the container through which the mains water can flow. From the cahmber a line leads to a stop valve connected to the second unit in such a way that, when pressure in the mains water chamber is balanced or exceeded by the pressure in the drain, a valve opens, whereas if the pressure in the container is greater, the valve closes. A choke is fitted in the drain between the container and the connection to the differential pressure units together with a non-return valve. A connection from the concentrate supply feeds the other chamber of the container. The mixer automatically recharges the container with concentrate so that a series of distribution points can be served simulatenously from the centre. Differential pressure units may be divided by a membrane into two compartments with monitors to prevent the possibility of the delivery of water without disinfectant.

Title: Cholesterol determination procedure - in which bound cholesterol is released using microbial cholinesterase
Inventor: BEAUCAMP KLAUS DR RER NAT
IPC: C12Q1/60
Filed: 1975-02-18
Abstract: In a process for the determination of total cholesterol or bound cholesterol by releasing bound cholesterol and subsequently determining the released cholesterol by known methods, the bound cholesterol is released using cholesterol esterase fom microorganisms (e.g. Candida rugosa ATCC 14830, Rhizopus sp. WS 90027 or Aspergillus sp. WS 90030). Reagents for the determination of cholesterol consist of microbial cholesterol esterase and a system for the determination of free cholesterol. Hydrolysis of the bound cholesterol is extremely rapid; thus, when the cholesterol determination is carried out with 0.1-0.3 mg. Candida rugosa ATCC14830 or Aspergillus Sp. WS 90030 acetone-dried powder, quantitative hydrolysis of bound cholesterol is effected within 1-3 mins. The determination is pref. carried out fully enzymatically (pref. using cholesterol oxidase for the determination of the released cholesterol). Advantageously, the cholesterol esterase and the enzyme for the actual determination are added simultaneously to the sample (e.g. a serum sample) under investigation. The cholesterol oxidase is pref. obtained by cultivating a microorganism or a cholesterol-contg. nutrient medium.
