Inventor: WEMHOFF MARK F
IPC: A62D101/43
Filed: 1991-05-03
Abstract: Treating metal contg. wastes (e.g. slurries, spent galvanic bath contents) comprises treating with a series of reaction media which culminates in an electrochemical redn. to the metals.  The wastes can be in the form of hydroxides, carbamates, sulphides, carbonates (or any combination) and first it is necessary to convert to the ionic forms. The following agents are required (1) oxidn. e.g. H2O2, (2) acid e.g. H2SO4, (3) chelating e.g. EDTA or citric acid and (4) redn. e.g. Na metabisulphite, other additives may be used to give a high concn. of metal ions and provide pref. environment for autocatalytic transformations. The oxidn. agent destroys all (in)organic S cpds., the chelator converts the metal salts and solids to the ionic form and the redn. agent coupled with careful pH control destroys residual oxidn. agent which inhibits autocatalytic galvanisation. A hydrolysis stabiliser (e.g. boric acid) controls the hydrolysis and after careful pH regulation and several solid removal processes the soln. is used for return to waste water treatment. USE/ADVANTAGE - Environmentally friendly process which can treat all types of metal contg. liq. safely to give metal residues without using electrolytic deposition, giving a non-toxic, easily treatable effluent.

Title: Hydrogen@ prodn. in vehicle using stirling engine - to convert IC engine waste heat into electrical energy for water electrolyser
IPC: B60K6/24
Filed: 1991-09-04
Abstract: Hydrogen is produced in vehicles by converting the waste heat of the engine into electrical energy, by means of a Stirling engine which drives an a.c. generator, for current supply to the accumulators in a hybrid vehicle or to the electrolyser in a hydrogen-driven vehicle. The electrical energy is converted, in the electrolyser, into chemical energy as H2 and O2 which are combusted in the engine cylinders to form steam. The Stirling engine extracts the energy content of the hot steam and is opt. also supplied with energy extracted from the coolant and the oil by a heat exchanger, the waste steam being condensed in a condenser for return by an electric motor to the electrolyser. USE/ADVANTAGE - The process is applicable to all types of vehicles (esp. hybrid vehicles) such as ships, submarines, automobiles, aircraft, rail vehicles and in industrial plants and factories. It provides energy recovery, hydrogen prodn. and battery charging (in hybrid vehicles) without noxious exhausts and the need for hydrogen tanks, provides increased engine power since the electrolyser also produces oxygen and only requires periodic topping up of a water tank.

Patent DE-4135959-A1 (DE)
IPC: G01B11/255
Filed: 1991-10-31
Abstract: The description relates to the measurement of the inclination of boundary areas in an optical system and a device for implementing the process. Starting with an auto-collimation process which determines the inclination of this boundary area in relation to a reference axis from the deviation of a light beam collimated on the boundary area to be examined and reflected on a position-sensitive photo-detection system, a twin-beam interferometer process with downstream evaluation electronics is provided which permits the separation of the interferogram, intensity-modulated according to the invention, of the boundary area to be examined from the unmodulated interference reflections of those not to be examined as far as interferogram intensities in the photon-noise range and thus offers a resolution in the deviation of the centre of gravity of the interferogram of the order of 10 nm. To modulate the intensity of the interferogram, the difference in the optical distance between the reference and test beams to the boundary area to be examined is time-modulated.

Title: High power converter or inverter using semiconductor elements in parallel - operates each bridge path of three thyristors by single pulse generator and counter circuit
IPC: H02M1/088
Filed: 1991-11-01
Abstract: A power switching solid state device for use in a parallel mode provides the basis of an a.c. inverter. An a.c. bridge circuit has three parallel thyristors in each bridge to form a 50 Hz system. The three parallel thyristors are operated by a firing pulse transmitter that has on the secondary side a triggered electronic counter that provides the phased signals for operating the three devices. This allows the number of pulse generators to be reduced to 6 from 18 for the full bridge. ADVANTAGE - Drives power semiconductor components sequentially in short time periods related to heat-time constants instead of simultaneously so that current distribution between the semiconductor components is independent of their individual technical data and circuit construction, avoiding the usual parallel switching factor reducing permissible loading.

Title: New DNA encoding squamous cell carcinoma antigen - allowing large scale antigen prodn. for use as diagnostic reagent or immunogen, also useful as hybridisation probe
Inventor: SUMINAMI YOSHINORI
IPC: C12N15/31
Filed: 1991-11-29
Abstract: New DNA fragment (I) has a base sequence which relates to an antigen (Ag) associated with squamous cell carcinoma (SCC). (I) encodes for all or part of a 370 amino acid Ag which is reproduced in the specification. Also reproduced is a 1711 base sequence for (I). USE/ADVANTAGE - Ag (which can be isoalated from SCC of the cervix uteri, pulmonary or oesophagal carcinoma, etc.) is known as a diagnostic reagent for SCC but is not easily produced on a large scale from human cancer cells. By expressing (I) in E.coli, animal cells, etc., Ag can be prepd. in large quantities. Ag can also be as an immunogen (to produce antibodies, also useful diagnostically) while the Ag-encoding gene can be detected by hybridisation with (I). Ag is homologous with serine protease inhibitors so may be useful therapeutically.
