IPC: C07K16/06
Filed: 1980-05-16
Abstract: Native immunoglobulin is treated, for the selective cleavage of the disulphide bonds between chains, with a sulphite ion in the presence, as oxidising agent, of a compound which is capable of forming a persulphate ion in water. In contrast to the use of oxidising agents which are generally known per se and which give agglutinated immunoglobulin derivatives of increased anticomplementary activity, the immunoglobulin derivatives obtained by this process have reduced anticomplementary activity, can be intravenously injected and are reconverted, within the body of the patient and without side effects, into the original immunoglobulin. By contrast with the known use of alkali metal tetrathionates, iodosobenzoic acid and alkali metal salts thereof, a copper(II) ion or molecular oxygen, the oxidising agents which can be used are industrially prepared, readily available and inexpensive compounds which lead, in a simple manner, to an end product of high purity which can be used without causing any unwanted side effects.

Patent DE-3100215-A1 (DE)
Title: "Rotary machine having a piston which is radially fixed but carries out axial working cycles, and preferably in operation is free of external momentum, both axially and radially"
Inventor: WANKE WILHELM
IPC: F01B9/06
Filed: 1981-01-07
Abstract: The invention relates to a rotary machine with positively-driven sequences of motion, suitable in particular for use according to the pump or compressor principle. The German Laid-Open Application P 2905380.3 discloses a similar machine, but this has two major drawbacks:     a) externally effective axial imbalance, b) non-positive, wear-susceptible axial movement between pistons and shaft. The machine according to the invention (Figure 1) overcomes these drawbacks. The pistons (3.1, 3.2) only carry out axial movements, and the shaft (2) with shaft collars (2.1, 2.2, 2.3) carries out the radial movements; without non-positive axial movement between pistons (3.1, 3.2) and shaft (2). Moreover, two pistons (3.1, 3.2) in each case are controlled in such a way, that synchronously opposite movements result in cancellation of the axial inertial forces within the machine. Radial inertial forces do not occur, as the radially rotating parts are symmetric. The machine according to the invention is thus free of critical wear points, is neutral in terms of externally acting inertial momentum and has an extreme power density.   <IMAGE>
Patent DE-3101642-A1 (DE)
Inventor: MOILLIET GUY
IPC: C02F3/26
Filed: 1981-01-20
Abstract: Heat can be recovered by biological generation of heat upon aeration of refuse, such as garbage or sludge, in an aeration vessel (11) by introducing oxygen-containing gas, such as air, in a closed cycle (11, 33, 31, 35) to thereby enrich gas withdrawn from the vessel with the oxygen, typically by reintroduction of gas withdrawn from an upper gas portion (43) of the vessel, after introduction of additional oxygen, for example controlled by a valve (65) into a lower portion of the contents of the aeration chamber. Control can be effected automatically, by a control unit (55, 55') through a valve (51, 51') or manually; automatic control can be effected, for example, by sensing oxygen or carbon dioxide concentration by suitable sensors (57, 59) within the vessel. To permit recovery of methane of high quality in a subsequent decomposition and methane recovery container, material withdrawn from the aeration vessel is degassed in degassing chambers (68; 69, 70), for example by storage for about 1/2 hour, and venting of emanating gases. Control of valves regulating flow from, and to, the aerating vessel and the degassing chambers (69, 70) permits preheating of freshly introduced refuse by the material withdrawn from the degassing chambers in a counterflow heat exchanger (17'), while preventing possible escape of non-aerated substances from the vessel (11) by isolating the aeration vessel (11) during introduction of new refuse, and emptying only a chamber (e.g. 69) of said degassing chamber system (68).

Filed: 1981-02-11
Abstract: The invention relates to a mains plug combination having a time switch, isolating transformer, connecting sockets for low-voltage apparatuses, battery charging combination with a changeover switch and indicator lights. The object of the invention is an apparatus which at the same time produces     - low-voltage AC for small AC apparatuses,   - low-voltage DC for small DC apparatuses and - low-voltage DC charging current for recharging NiCad batteries, and in the case of which - the operating time can be preselected by a time switch which can be bridged for the charging process.   According to the invention, this object is achieved by means of an apparatus which has a time switch (3) (via which all the types of power supplied by the apparatus are switched) in a mains plug housing (1) (see drawing) with mains plug pins (2). It is connected upstream of an isolating transformer (4) and a rectifier (charging combination) (5), which produce low-voltage AC and low-voltage DC respectively, which can be extracted via connecting sockets (8, 9). The time switch can be bridged by the time-switch bridging switch (6) for the battery-charging process. The changeover switch (7) distributes the low voltage supplied by the isolating transformer to connecting sockets (8 and 9). Connected upstream of the latter is a rectifier (charging combination 5). Accordingly, the apparatus can be used universally for small low-voltage apparatuses. <IMAGE>

Title: Hydraulic operating device for controlling the working and stoppage phases of machines or machine tools
Inventor: KUTTRUF WERNER
IPC: F15B20/00
Filed: 1981-03-17
Abstract: A hydraulic operating device for controlling the active and stoppage phases of machines or machine tools is specified, with two main control valves which can each be guided into their on- and off-positions by means of a pilot-control valve and pass the pressure-medium flow from the supply-pressure source to the consumer when their valve pistons are simultaneously in the on-position and, when the valve pistons are simultaneously in the off-position or assume their alternative operating positions, produce a communicating connection between the consumer and the tank and thereby stop the machine. In order reliably to prevent the machine from being able to be switched on in the event of a malfunction of one of the components of the hydraulic operating circuit, the supply pressure is fed to the consumer via a flow route which comprises through-flow paths of the main control valves, which are connected in series only in their simultaneous on-position, and a hydraulic locking circuit is provided which, after a change-over of the main control valves into alternative operating positions, holds the control pistons of the main control valves in these alternative operating positions.
