Abstract: A supported precious metal catalyst for the high-temperature combustion of a hydrocarbon comprises 1-10% by weight in total of one or more precious metals on a refractory metal oxide support material, further comprising 1-20% by weight in total of one or more stabilizing metals of elements selected from rare earths and Groups IA, IIA, and IIIA of the periodic table of the elements, wherein at least part of the precious metal is present as a mixed metal oxide with one or more of said stabilizing metals. The catalyst may be prepared by impregnating the refractory metal oxide with a solution of the stabilizing agent and drying and calcining the impregnated support in a first calcination step at a temperature in the range 400-600 oC to form a modified support material and then impregnating the modified support material with a solution of the precious metal and drying and calcining the resulting material in a second calcinations step at a temperature in the range 600-950oC. A reactor for use with the catalyst is also disclosed.

Filed: 1979-06-11
Granted: 1982-01-14
Abstract: In the manufacture of sheet metal elements or strip having a catalytic surface structure, a mixture of skeleton material powder, and of Raney alloy powder is rolled onto the starting sheet metal element or strip substrate, sintered in a reducing atmosphere, whereafter the soluble component of the Raney alloy is dissolved out. To ensure an adequate adherence of the catalytic surface structure, the operation in which the above-mentioned mixture is rolled onto the substrate is accompanied by a simultaneous cold-working of the substrate with a deformation of 20 to 60% within each cold-forming step. The coated sheet metal element or strip substrates or any spherical bodies made therefrom serve as electrodes in electrolytic processes.

Title: Composite cover and its application
Inventor: KLASCHKA RUDOLF
IPC: H01G9/12
Filed: 1981-05-15
Granted: 1984-11-22
Abstract: The composite cover plate for the locking of compartments of electric components, especially for locking the metallic can compartment of an electric condenser consists of an aluminum disc sandwiched between a rubber coating applied on its one side and a disc of artificial material on its opposite side. The disc of artificial material is forced flush against the free surface of the aluminum disc by electric lead-through elements, especially lead-through rivet elements. The rubber coating is disposed around the outer edge of the aluminum disc extending up to a ring-shaped edge portions on the side of the aluminum disc on which the disc of artificial material lies. This ring-shaped rubber coating encloses the outer edge of the disc of artificial material in substantially definite form. Each lead-through rivet is secured against displacement through riveting on the bottom side of the disc of artificial material. Sealing of the lead-through rivet is effected in that the area provided on the head of the rivet is forced onto the surface of the rubber coating through the riveting process. The lead-through rivet is led through an opening in the aluminum disc whose diameter is larger than the diameter of the shaft of the lead-through rivet so that the lead-through element is insulated against the aluminum disc. A burstable valve is provided through a weakening of rubber coating over an opening in the aluminum disc and a coaxial opening in the disc of artificial material.

Title: Coin handling apparatus
Inventor: EGLISE DAVID
IPC: G07F5/24
Filed: 1982-09-29
Granted: 1989-10-19
Abstract: A microprocessor-controlled coin handling apparatus, for example for a vending machine, has a plurality of change tubes each of which is provided with a single level sensor for determining whether or not the number of coins in the respective tube is greater than a predetermined number. The microprocessor keeps a count of the coins in the tube. When the power is turned on, the count is set to zero if the sensor indicates that the number of coins is less than the predetermined number, and is set to a predetermined "full" number otherwise. The microprocessor increments and decrements the counts as coins are delivered to and dispensed from the change tubes. Whenever the level of coins rises or falls such that the sensor output changes, the coin count is automatically corrected. Also disclosed is a non-volatile memory for storing parameters determining how the coins are handled. Keys are provided for accessing and altering the contents of the memory. Some contents are accessible in a first mode, whereas other contents are inaccessible in this mode, and require a second or third access mode to be entered. At least one location can be altered in a first manner during one of the access modes, and in a second manner only during a different access mode.

Title: Power supply circuit for an electrostatic dust separator
Inventor: EISERLO FRIEDRICH
IPC: H02M9/02
Filed: 1983-10-22
Granted: 1986-08-28
Abstract: The pulse voltage for the electrode (12) of a dust separator (10) is generated by a thyristor circuit (19) to be transferred to a dust separator through a transformer (16). It being possible that voltage arcings take place at the dust separator (10), there is the risk, in case of a blocked thyristor (20) that from the secondary of the transformer (16) a high voltage is produced at thyristor (20) to destroy the thyristor. To avoid such an occurrence, a detector (27) is provided which is only responsive to sudden voltage drops whereupon the thyristor (20) is enabled to become conductive so that the energy of the secondary circuit may be discharged to the storage capacitor (24) in the primary circuit.
