Inventor: LOEWE HEINZ DR
IPC: A61K31/41
Filed: 1973-06-26
Abstract: The novel anthelmintically active 2-carbalkoxy-amino-benzimidazole-5(6)-phenyl ethers and thioethers of the formula I <IMAGE>  wherein     R1 denotes alkyl having 1 to 4 carbon atoms, R2 and R3 independently of one another each denote hydrogen, hydroxyl, alkoxy having 1 to 4 carbon atoms, halogen, trifluoromethyl, alkyl having 1 to 4 carbon atoms or carbalkoxy having 1 to 4 carbon atoms in the alkoxy radical,   R4 denotes hydrogen or chlorine and   X denotes oxygen of sulphur, are prepared by reaction of appropriately substituted o-phenylenediamine derivatives with an appropriately substituted dithiomethyleneamino-formic acid ester. The compounds are valuable chemotherapeutics for the control of parasitic diseases in man and animals. They are particularly active against a large number of helminths, for example Haemonchus, Trichostrongylus, Ostertagia, Strongyloides, Cooperia, Chabertia, Oesophagostomum, Hyostrongylus, Ankylostoma, Askaris and Heterakis.

Title: Iron powder production - by reduction of fine-grained iron ore, heating the prod. and grinding
Inventor: FOERSTER ECKEHARD DR-ING
IPC: C21B13/14
Filed: 1973-08-25
Abstract: Fe ore is ground to a size of Blaine surface area of ca 1800 cm2/g and pelleted with an organic binder. The pellets are then reduced by a direct process to a 90-99% degree of reduction, so that the C content of the reduced pellets is just sufficient for reducing the residual oxygen in a post-reduction stage in which the pellets are heated in a rotary kiln at 950-1120 degrees C in an H contg. atm. The heat treated pellets are then cooled and ground to about 160 u. The pellets are heated in the rotary kiln in an H2 atm. in which the rate of H2flow is adjusted so that the gas at exit from the kiln has a water vapour content of ca 20%. After grinding of the heat treated pellets a second heat treatment is applied in an H2 atm. at 750 degrees C pref. in a beam furnace.
Patent DE-2345413-A1 (DE)
Title: Twin cylinder pump for feeding filter presses - has float operated induction switches to prevent dead centres coinciding
Inventor: TUCHENHAGEN OTTO
IPC: F04F1/10
Filed: 1973-09-08
Abstract: Two cylinders have ball inlet and discharge valves from common inlet and discharge pipes. Liquid is expelled from the cylinders by compressed air admitted through solenoid valves and allowed to enter by other solenoid valves as the air is exhausted through a third set of solenoid valves. Each cylinder contains a float which actuates induction switches at the top, middle and bottom of the cylinder as it passes them. The middle switch starts the discharge stroke of the other cylinder, the bottom switch starts the suction stroke of its own cylinder and the top switch stops the suction stroke of its own cylinder. The middle switch ensures that one discharge starts before the other ends so that there is no dead centre without pressure at the outlet.

Title: Safety regulator for pressure surges in district C.H. plant - has hand setting and automatic control from temp pulse
Inventor: STREMPEL ERICH
IPC: F24D10/00
Filed: 1973-10-15
Abstract: Safety regulator for a household central heating plant connected to district heating mains, with change of amt. of heating medium giving the heat removal, has a regulating element in a housing moved, after setting stable press. drops by hand and/or with regulating elements, automatically, e.g. directly by air-conditioning or room temp. pulse such that a variable, fixed settable max. passage opening can be controlled at will, and each intermediate position gives a preset opening down to the closed position. The positions correspond to similar-ratio heating medium amts. of respective heat requirement. As required by separate action, the passage opening and/or the pressure drop acting on it, can be adjusted further to another desired amt. of heating medium. No press. fluctuation occur on regulation of the amt. of heating medium.

Title: Regenerating nitriding and carbonising fused salt baths - contg. excess carbonate by adding polymeric carboxylic acid amides
Inventor: BEYER HERMANN DR
IPC: C23C8/40
Filed: 1974-02-27
Abstract: Regeneration of carbonate-contg. fused salt baths, for nitriding and/or carbonising metal workpieces, is effected by adding polymeric carboxylic acid amides, pref. polymeric urea, e.g. prepd. by heating urea to 400-600 degrees C. Excess carbonate is converted to cyanate; no cation-contg. cpds. are added and bath vol. is not increased; no fusion bath quantities need to removed at each regeneration; and only cyanates are formed, thus allowing nitriding or carbonising to take place in a cyanide-free system, preventing formation of toxic waste waters. Polymeric amides of substd. carboxylic acids are pref. used.

Title: Hollow glass vessels mfr. by the double blow process - using simple design for upper air inlet
Inventor: JONES RONNIE G
IPC: C03B9/30
Filed: 1974-09-30
Abstract: A gob of glass is placed in the cavity of the tubular mould and compressed air fed in at the top so the gov fills the lower part of the mould; the upper air inlet or top-plus is then turned to the "off" position and air is blown into the bottom of the mould to form the hollow shape required. No upper-cone or -funnel is used with the top-plug, the plug being lowered into the mould to make a seal. This seal is pref. made by two mating conical faces, one on the plug, the other in the mould. As the plug does not have to be removed to extract an upper funnel, output is faster.

Title: Pneumatic safety lock for train doors - has pressurised air cylinder with driver's remote control
Inventor: SCHMITZ RUDOLF WERNER
IPC: E05B65/42
Filed: 1974-11-05
Abstract: The safety lock on the door is maintained locked during travel by a pressurized lock cylinder. An open conduit branching off the train brake line supplies the pressurized air to the lock cylinder, constantly pressing forward its locking piston. When the train stops, the train driver closes a blocking valve, to stop the air supply and to release the cylinder from its locked position. This remote control is also used for relocking when the train starts to move. The arrangement enhances the safety and can be applied to existing railway carriage structures.

Title: Swivel-mounted drop-down food slicer with crumb collector - has grooves open at one end leading into swivel collector channel
Inventor: KAISER GUSTAV
IPC: A47J45/02
Filed: 1975-03-14
Abstract: The fastening mechanism for the swivel-mounted drop-down bread slicer also includes a swivel-mounted transverse crumb collecting channel mounted on the front. Several grooves for the crumbs are disposed longitudinally in the base plate of the slicing machine to which the transverse collecting channel is attached for swivel movement. The grooves are closed at the rear end in the feed direction of the article to be sliced and are open at their end facing the crumb collecting channel. Thus the crumbs which accumulate during the slicing process are swept into the individual crumb grooves by the advancing sliced bread and, since the back of the grooves are closed, the crumbs cannot be pushed out onto the table top.
