Title: Emulsion for removing corrosive and poisonous agents from small items - comprises aq. soln. of solvent, emulsifier, water soluble active agent with low electrolytic activity etc.
Inventor: ALTMANN HANS-JUERGEN DIPL ING
IPC: B01D17/02
Filed: 1989-09-04
Abstract: Small items of equipment such as electrical testing instruments at potential risk of corrosion, and which have been contaminated by ABC chemical warfare agents are purified by an emulsion contg. water-soluble active material with (de-ionised) water, solvent and an emulsifier. Emulsion residues are removed by solvent contg. 0-13 wt. % emulsifier. Both treatment emulsion and this residue removing soln. which may be sprayed or the equipment, are separately collected and treated for re-use. The mixts. arising in these treatments are effectively sepd. by gravity, with used material replaced by fresh liq. ADVANTAGE - Considerably smaller amts. of emulsion and cleaning soln. are needed, which reduces transport costs and problems as well as basic material costs.

Abstract: A combination immunostimulant for increasing the body's own immune defence mechanism consists of a combination of extracts of Eleutherococcus sertiocus, spleen and thymus as the active ingredients of Dr Weger's natural immunostimulant, the individual components only causing a significant measurable increase in the immune defence mechanism when used together. An immunostimulant for prophylactic use consists of an alcoholic extract of Eleutherococcus sertioccus dissolved in blackcurrant juice in ratio 1:4. This prod. can be used as an immunostimulant for prophylaxis of healthy people and as a natural prod. to provide trace elements and vitamin C. USE/ADVANTAGE - The combination prepn. provides bodies weakened by AIDS, cancer, leukaemia etc. with the necessary building blocks, such as glycopeptides required for immune defence. The combination increases the T-cells after damage by HIV, increases the body's own interferons and immunoglobulins, increases the overall feeling of bodily health, increases body weight which has been reduced by AIDS and causes considerably recovery or even healing of opportunistic diseases resulting from immune deficiency. The spleen and thymus extracts enable Eleutherococcus to develop its adaptogenous effect, i.e. in the direction of normalisation. The combination is synergistic. The mixt. of Eleutherococcus and blackcurrent juice helps the body's own defence system to recognise and kill potential cancer cells, thus inhibiting the occurrence of canc na

Title: Dense spherical powders mfd. by modified spraying technique - using high temp. stage after spraying to effect densification
Inventor: SCHUMACHER MANFRED DR
IPC: B01D1/18
Filed: 1991-04-08
Abstract: Mfg. dense spherical powders (with a particle size range of the order of 0.05-5 microns) by modified spraying. The porous or hollow spherical powder produced is dried and then densified in a subsequent high-temp. stage by the effect of a melt formed. This gives a fine particulate powder which has a high sintering activity and which may be amorphous or nanocrystalline. A device for carrying out the process has a high-temp. cell for densifying the powder particles via melt formation. The spray soln. is an aq. soln. of nitrates, chlorides and/or acetates. Alternatively, a non-aq. soln. may be used. As a further alternative, a suspension or a mixture of a suspension and a soln. may be used. The carrier gas may be oxidising, reducing or inert. The high-temp. cell may be resistance-heated, gas-heated, or heated by radiation, by a plasma, by a laser, or by an arc. An. aq. soln. is prepd., contg. Ba(NO3)2, Cu(NO3)2.3H2O and Y(NO3)3.6H2O. The soln. is converted into a mist using an ultrasonic atomiser. The droplets have a dia. of 1-5 microns. 1 kg of product is obtd. from 30 l of soln. The resulting particles have a dia. of 0.2-1 micron. Depending on the process conditions and the temp., the powder is either amorphous (T = 1200 deg. C) or partially crystalline (T = 1100 deg. C). USE/ADVANTAGE - Used to produce complex powders. The process is an improvement over methods such as spray-calcining, reaction srpay-drying, spray-roasting and spray pyrolysis, in that it produces finer, denser particles. It is advantageous compared with soln. combustion techniques in that the prod. is homogeneous

Each pair of rollers is driven by a gearbox, the lower one having a horizontal drive shaft, the upper one having an inclined drive shaft with universal joints. The gearbox ensures that the rollers have identical angular speed. ADVANTAGE - Robust construction accepting variable cable diameters.

IPC: E01B31/17
Filed: 1991-06-13
Abstract: The grinding belt is for levelling the surface of a rail (3) of a track, after application of metal by build-up welding. It has a frame (1) with drive pulley (4) and deflection pulley (5), with a belt (6). There are support bearings, and a movable support shoe (10), engaging on the belt. An adjuster is provided for movement and contact pressure of the shoe on the belt.
