Title: Sealed continuous casting mould cooling water circulation - system - with inert gas pressurised overhead tank
IPC: B22D11/055
Filed: 1971-01-13
Abstract: Continuous casting mould cooling installation comprises a sealed overhead cooling water tank, into which is fed the used cooling water and from the bottom of which feed coolant water is abstracted through a line in which there is a circulating pump, a heat exchanger and a one way valve. The space above the water in the tank is kept under an excess inert gas pressure acting as an elastic pressure pad. The tank is fitted with an emergency supply line to the mould with a one way valve, which opens when the pump stops. In the prefd. set up gas pressure of between 0.3-0.4 atmos. is maintained in the tank. A level difference of =5m should exist between the bottom outlet of the emergency supply line from the tank and the casting mould. The system permits a relatively long duration of emergency supply as even then coolant is recirculated. The inert gas prevents O2 pick-up by water and consequent accelerated corrosion action.

Title: Immunological test for syphilis - using antigens bound to carrier particles at ph 8
Inventor: DROSTE RENATE
IPC: G01N33/571
Filed: 1971-11-04
Abstract: In a microscope slide test for the diagnosis of syphilis, in an immunological reaction with human serum scientifically recognised antigens bind syphilis reagins in an optimal pH medium of 8.2. Suitably a latex soln. buffered to pH 8.2 with glycocoll buffer is mixed with a conc. antigen (e.g. cardiolopin) soln. to give a suitable reagent; carrier particles other than latex can also be used. The test is carried out by mixing the reagent with serum and reacting 10 mins; positive reaction is indicated by coagulation visible to the naked eye. The test is thus rapid and simple, and is suitable for screening e.g. all hospital patients or blood donors without great expenditure of time, money and equipment.

Title: Binder for flux for arc welding rod - free of silica and opt free of alumina
Inventor: DELONG WILLIAM T
IPC: H01T4/12
Filed: 1972-02-15
Abstract: Flux coating for arc welding rod comprises a finely divided binder and flux, the binder being readily dispersable in water and comprising a fluoride, a mixture of fluorides, an aluminate, an alkali hydroxide or carbonate, at least one of these supplementary materials being present when binder contains an aluminate. The binder is present in sufficient amt. to ensure a sufficient strength after adequate mixing with flux and water and drying and firing at 340-510 degrees C. The prior silicate binders, tended to form unsuitable slags with the flux. For some purposes the aluminate is omitted. The mixts. have similar humidity to prior art silicate mixts. and have similar resistance to rehydration.

Title: Fluidics controlled conveyor system - for singling and feeding to packing stations of delicate objects esp. filled sweetmeats
Inventor: FRANK EBERHARD DIPL ING
IPC: B65G47/29
Filed: 1972-09-07
Abstract: The delicate pieces pass on a first conveyor to a "gate" in the form of a pair of inflatable membranes, one at each side, which when inflated protrude inwards to act as a stop. Downstream of the gate is a puffer nozzle sensing system which provides the input signal regulating the pressurisation of the membranes such that one piece is released at a time onto a faster second conveyor via an intermediate belt and pin type transfer mechanism whose belt speed is synchronous with the second conveyor. There is reduced waste from handling damage.

Title: Alkali phosphate fertilizer prodn. - by igniting raw phosphate with silicic acid in the presence of alkali hydroxide
Inventor: HOLST RUDOLF DR
IPC: C05B13/02
Filed: 1972-12-22
Abstract: Process for producing citrate-sol. ignited alkali phosphate with fertiliser action in which natural cacium phosphates are subjected to thermal digestion in a rotary oven at 900-1300 degrees C. with aq. alkali hydroxide soln. in the presence of silicic acid (sand), 30-80 wt.% of the alkali hydroxide soln. being added at is not 400 degrees C. so as to ensure (a) rapid evaporation of the water, (b) rapid reaction, and (c) (due to the rotary motion of the oven) good homogenisation, is improved by bringing 1-50 wt.% of the alkali hydroxide soln. into contact with the raw materials at the feed end of the rotary oven by mixing with the cold raw phosphate(s) and mixt. outside or inside the rotary oven. Process avoids problems caused by dust at the feed end of the oven, since dust carried by oven waste gases is removed on contact with the moist raw material mixture or with injected alkali hydroxide soln., and gives better utilisation of the heat of the waste gases.

Title: Industrial effluent sepn. into pure water and sludge - by centrifuging and four-stage evapn.
Inventor: CASPARIAN ROBERT EDWARD
IPC: C02F1/04
Filed: 1973-08-10
Abstract: Ind. effluents are turned into pure water and a concd. solids residue by thermal evapn. and condensn. of the water vapour. The solids residue is mixed with a non-volatile oil so that it can be conveyed by pumps. Further heating removes the residual water to produce a residual sludge prod. free from water. This process recovers the whole of the water from an effluent in a purified state. The sludge can be used either as high-calorie fuel or as fertiliser.

Title: Central lock system for electronic office machines - allows keys belonging to operator to be inserted in any position
Inventor: MAHNE FRIEDRICH
IPC: E05B49/00
Filed: 1973-12-05
Abstract: The system has several independent, profiled, markings in different arrangements, corresponding to a code on code keys. The keys are allocated to an operator, who can select calculation storages, and control functions, by insertion into a correspondingly profiled recess of a key lock. This contains scanning members, which are activated by the markings, and which produce code signals according to the desired selection. The code keys have similar symmetrical, non-round profiles. One of the profiled surfaces of each key has an additional marking. This marking has additional scanning members in the key lock corresponding to the number of profiled surfaces of a key, to determine the momentary key position.

Title: Enclosed feed to paper sheet separating mechanism - has periodically vibrated barrier plate in item path transmitting aligning impulses
Inventor: KLUGE WILLI
IPC: B65H3/06
Filed: 1974-01-14
Abstract: The machine is particularly for delivering newspaper proofs to a separating mechanism, and incorporates a conveyor belt transporting the overlapping enclosures to the latter. A barrier plate extends into the path of the enclosures, and is periodically caused to vibrate by a drive mechanism. The direction of vibration of the plate is such that shock impulses are transmitted to the enclosures in the opposite direction to that in which they travel, the effect being to align them. The front of the plate can lie at an acute angle to the direction of travel of the items. The plate can be arranged so that with each complete vibration cycle it performs a movement against the direction of travel and one at an acute angle to it.

Title: Noise period measuring device - designed to be worn or carried by exposed person
Inventor: EDER HEINRICH
IPC: G01H3/14
Filed: 1974-06-26
