Title: Conditioning and de watering of effluent sludge - by mixing with flocculants
IPC: C02F11/12
Filed: 1972-01-28
Abstract: Sludge is vaporised into small droplets, passed through a lot gas atmosphere and into a bath for flocculant (e.g. synthetic polymer) addition.

Title: Coating steel with bright chromium - by continuous vapour deposition
IPC: C23G5/00
Filed: 1972-07-27
Abstract: Method for coating steel with a layer of bright chromium by vapour deposition whereby the steel is heated in a non-oxidising atmos at is not 482 degrees C and then passed through a chamber at a pressure of 0.0001-0.03 mm of Hg of a mixt. of N2 and H2, in which a thickness of chromium >0.01 inch is applied to >=1 face by vapour deposition.

Title: Spray-clarifying sugar crystals in drying centrifuge - with reduced shock of spray impact on thickened crystal layer
Inventor: MERCIER ANDRE
IPC: C13B30/10
Filed: 1974-06-17
Abstract: A continuous drying centrifuge, used for filtering out sugar crystals from massecuite, has a nozzle for spraying crystals collected on the centrifuge screen with a clarifying liq. Means are provided to increase the thickness of the layer of crystals in the sprayed area and the clarifying liq. is sprayed on to the crystals by a gas stream which discharges the liq. as tiny droplets having a speed component in line with the tangent at the point of impact which is practically the same as the speed of crystals at that point, while the speed component normal to that point is negligible. The liq. can be introduced as a fine spray into the gas stream or can be aspirated into gas being passed through a venturi; the gas is pref. steam. Thickening the crystal layer is pref. effected by fitting a crystal discharge restrictor ring to the top of the basket and/or part-way up the basket. Device is for clarifying crystals of sugar before discharging them from a conical centrifuge basket. The thickened crystal layer and reduced shock of applicn. of washing spray avoid erosion of the layer and improve the clarifying process.

Title: Adaptation of specific computer to take accounting cards - uses paper presence contact to have electronic coupler transfer line feed and carriage controls
IPC: B41J11/48
Filed: 1975-07-17
Abstract: The convertor system includes a mechanical adaptor fixing the accounting card inserter onto a terminet 30. A plate guides the card at the moment of its automatic descent under the control of the card inserter. A coupler automatically transfers the line feed and carriage return commands of the terminet 30 to the inserter when an account card is presented at the inserter. The transfer of commands is triggered by the 'paper presence' contact on the automatic inserter/ejector. The printing security device has a micro contact which opens as soon as the printing head is displaced. the microcontact controls the motor circuit of the card feed.

Title: Purifying waste water of high organic content - first acid anaerobic, then aerobic, then anaerobic methane fermentations
IPC: C02F3/30
Filed: 1976-09-13
Abstract: Process for the purificn. of waste water having a high content of organic material comprises several stages. The first stage is initially anaerobic fermentation by means of a microbial culture at 20-50 degrees C in acid medium for a residue time of 0.1-0.8 d. kg-1.m3 with conversion of the contained oxygen to a mixt. of organic acids; this is followed by aerobic fermentation for a residence time of 0.03 d. kg-1. m3. At the second stage the mixt. is submitted to an anaerobic methane fermentation by an anaerobic microorganism culture for 6-15 days. The resulting mixt. may then if desired be further purified by a second aerobic stage. By present methods involving an anaerobic followed by an anaerobic stage, in the 1st stage, e.g. methane fermentation, the acids formed lower the pH and inhibit the fermentation. Chalk is used to neutralise the acid but this complicates the process. The above process converts the acids to CO2/water resulting in simplification of the process and avoidance of the use of chalk.

Title: Automatic speed limitation of generator - is controlled by tachometer operating contactor supplying power to electromagnetic brake
IPC: H02P29/00
Filed: 1976-09-15
Abstract: The speed of rotation of an alternator or generator is controlled automatically to prevent racing with consequent problems for the installation. A separate power supply is used for slowing the machine and may also be used for safety lighting or for battery charging. A machine (M) to be controlled is coupled via a shaft (1) to a braking control system (2) comprising several magnetic discs opposite electromagnets powered by the generator (3). Foucault current effects oppose rotation of the discs to control the speed of the machine. A tachometer (4) provides a variable current controlled by a speed sensor (5) which operates a contactor (a) when demanded speed is achieved. This action powers the braking control system (2) to control machine speed.

Title: Gas actuated planing ignition system - uses high energy electromagnetic rays to heat metal to ignition temp. (SW 25.4.77)
IPC: B23K7/06
Filed: 1977-03-18
Abstract: The system ignites gas planing equipment for a metal workpiece by preheating a set amt. of the metal to ignition temp. Radiation is effected by one or more high-energy electromagnetic rays irradiating the point on the workpiece surface, ignition being produced with an energy flux of more than 1000 watts per sq. cm. There can be a burner directing a current of oxygen to the planing zone of the workpiece and a radiation device to pre-heat the metal. An optical system connected to the radiation source directs radiation from the latter to the workpiece. The source can be of the spot or linear type, the optical system (11, 12, 13) in the latter case transmitting a linear pattern onto the workpiece.
