Title: Copper alumina catalyst compsns - for oxidation, dehydrogenation and oxyhalogenation reactions
Inventor: FOUCHER JUN WALTER DAVID
IPC: B01D53/86
Filed: 1972-07-22
Abstract: Copper-alumina compsns. for catalytic applications in liq. or vapour phase systems comprise a support material and an adherent active layer (thickness 1-100 mils, pref. 10-100 mils) of crystalline material represented by formula (CuO)x.(Al2O3)y.nH2O (where x = 1-3; y = 1-4) and having a defined X-ray diffraction pattern. The compsns. are made by treating the support material with an aq. mixt. of alkali metal aluminate copper and ammonia (mole ratio NH3/Cu 4, Cu/Al = 1.5-5.0) at 100-212 degrees F (pref. 100-150 degrees F)/3-72 hrs, followed by calcining at 300-1000 degrees F. In a pref. system sodium aluminate soln. is added to ammonical copper (as sulphate, nitrate, carbonate or chromate) soln. in presence of the support. Fouling of the catalyst within its bulk does not occur, since it is only present as a layer on a support and is not of itself porous, and heat exchange is rapid.

Title: Carpet printing flowline speed control - with selector to change basic speed of certain loop roller drives
IPC: B41F33/00
Filed: 1973-07-27
Abstract: A flow line of machines used for the continuous printing of carpets uses a basic speed for all machines, with four carpet loops separating the printing unit from the washing and drying units. To remove longitudinal folds from the loops each loop roller drive motor can be selected by a selector switch to be cut off from the potentiometer which sets the basic speed and to be connected to another potentiometer which superimposes a different speed to the basic speed. This obviates the necessity of stopping the rest of the plant and there is no prodn. loss if folds have to be removed.

Title: Motor vehicle steering column switch - has measuring lever rotatably mounted on support with force sensor abutting switch actuator
Inventor: HAAG HELMUT DIPL ING
IPC: H01H11/00

Abstract: The steering column switch has an actuator accommodating the switching characteristic. The accommodating device has a socket carrying a rotatable measuring lever with a force sensor, abutting the switch actuating element. The switch is so mounted on the socket that the axis of rotation of the switch actuator coincides with the axis of rotation of the measuring layer. A measuring potentiometer is displaced in the synchronism with the measuring lever, a voltage coresponding to the angular position being tapped at the potentiometer, which is applied to the X input of a two-coordinate recorder. The displacement force affecting the force sensor is transduced into an electric voltage, applied to the Y input of the recorder. Preferably the measuring lever and potentiometer are rotatable by a controlled motor via a gear drive.

Preferably the dome has an approximately triangular cross section. The pn-junction may be located at the base of the dome and bounded by planar surfaces. The envelope lines of the dome may have a convex course. The pn-junction forming surface may have an edge arcuation, similar to that of the dome parts nearest to the pn-junction. The sharp angle of the dome cross section may be twice as large as the boundary angle of the total reflection of the substance, from which the dome is formed.

Title: Continuous automatic water-softening system - with alternative exchanger when one is being regenerated
Inventor: ANNEN ROBERT C
IPC: C02F1/42
Filed: 1974-04-23
Abstract: The system in which the supply of soft water is not stopped during the regeneration cycle, comprises two ion exchange beds which are connected to a device which is sensitive to the hardness of the water. When the first bed is exhausted, the second is used while the first is being regenerated. When this is complete, the two beds are again connected in series but in the reverse order. Brine is contd. in a reservoir which is connected by various valves and and a pipe system to a programmer. When the probe indicates that the resin in one bed is exhausted, it is washed with hard water, the brine is introduced and, after the latter has acted, the resin is rinsed with hard water and reintroduced into the softening circuit. In this way the softened water is supplied continuously. The capital cost is reduced because smaller exchanger vessels can be used.

Title: Fuel element cassette for boiling light water reactor - with fuel rods contg. burnable poison for neutron capture at a rate compensating fuel depletion
Inventor: FREDIN BO DIPL ING

Abstract: Fuel element cassette, partic. applicable to boiling light water reactors, comprises vertically orientated fuel rods in a square lattice pitch interspaced with a number of rods contg. dispersed burnable poison in the form of a fine dispersion of Gd2O3 in Uo2. The spatial distribution of the fuel elements contg. Gd2O3 creates absorber zones where the intial neutron absorption should be proportional to the square root of the amt. of Gd23 with neutron absorption decreasing at a linear rate with time and with an absorption factor approximating to the line of the curve of excess reactivity. Dimensionally the absorber tablets of Gd2O3 have a height to dia. ratio either 50% larger or 25% smaller than the UO2 tablets and six basic axial combinations within the fuel element capsule materialise the required neutron absorption zonal distribution.
