Patent EP-0069450-A1 (EP)
Inventor: HOUTS THOMAS MICHAEL
IPC: G01N33/53
Filed: 1982-05-18
Abstract: Vitamin B 12  in liquid samples, such as human serum, is assayed by a competitive binding technique using intrinsic factor and certain labelled vitamin B 12  derivatives. The labelled derivatives are formed from the (d)-monocarboxylic acid isomer of vitamin B 12 , which isomer is free from other monocarboxylic acid isomers (and derivatives thereof) of vitamin B 12 , by binding to the (d)-isomer, via the carboxylic group, a compound which is itself a label (e.g. an enzyme) or which comprises a label (e.g. a fluorophore), or to which a label is attached (e.g. a histidine ester to which 125| is attached). The labelled derivatives of the (d)-monocarboxylic acid of vitamin B 12 , free from other isomeric monocarboxylic acids and derivatives, are novel and constitute one aspect of the invention.

Abstract: @ Potatoes which are to be graded according to their size prior to further processing, for example in the manufacture of a snack food product, are deposited in a hopper 16 at the lower end of an upwardly inclined walking beam conveyor 18. Pockets 35, 37 formed in the conveyor 18 pick up potatoes from the hopper 16 and convey them along the conveyor by transferring each potato from pocket to pocket. Any potatoes whose dimensions are greater than those of the pockets 35, 37 are either not picked up or fall out of the pockets under gravity as the conveyor 18 is operated and drop back into the hopper 16. Periodically, a base wall 17 of the hopper 16 is opened to discharge the accumulated large-size potatoes therefrom.

Abstract: The identification numbers of an integrated component may be determined by forming, during the manufacturing of the component, open and closed patterns of diode links between the component input and output pins and a positive voltage bus in the circuitry of the component. The cathodes of the diodes are coupled to a positive circuit bus and therefore the identification circuitry is isolated during operation of the functional circuitry. The open and closed pattern of the links are a binary representation of the component identification number which is read out by an ohmmeter or similar current-sensing type of instrument, the negative terminal of which is connected to the positive voltage terminal pin of the integrated circuit component to therefore forward bias the diodes to provide a current path through the closed links in the binary pattern.

Abstract: The present invention is directed to a dental spray hand piece which has a valve for controlling the flow of an agent through an agent line that extends through the hand piece to a spray nozzle and an arrangement for preventing dripping of the agent from an end of the nozzle when the valve stops flow of the agent through the line, characterized by the arrangement for preventing dripping including a hose section of elastic material being positioned between the valve and the nozzle, a thrust piece for acting on the hose section in an arrangement for moving the thrust piece from a position engaging the hose section and a second position partially deforming the hose section from an enlarged cross-section to a cross-section of the flow through the valve. Thus, when the valve stops flow the hose section resumes its enlarged cross-section which causes a suction to draw fluid in the line between the valve and the end of the nozzle inward from the end of the nozzle.

Abstract: An excavator wheel (15) provided with an annular array of peripheral scoops (16) is rotated about a horizontal axis while the wheel is moved along the terrain alongside a railroad track. The axis of rotation of the wheel is positioned selectively to be disposed within the range of perpendicular to the longitudinal extent of the track to substantially parallel thereto, whereby the scoops excavate a ditch correspondingly in the range of a narrow trench having a width equal to the transverse extent of the scoops to a wide ditch having a profile corresponding generally to the circumference of the wheel. The wheel is carried on the distal end of a boom (20) having the opposite end mounted to a wheeled support. The wheels are carried on suitable trucks (53) adjustably connected to the support to permit leveling of the support. In one form, the wheel is reversibly rotated and provided with double-ended scoops to permit excavation in either direction of rotation of the wheel. In one form, the wheel is swingable about a vertical axis (18) on the distal end of the boom so as to be positionable on either side of the boom in use. The wheeled support, in one form, is provided with a laterally opening recess (60) for accommodating the wheel in a storage position. The excavated material, in the illustrated embodiment, is conveyed from the excavator wheel by conveyor belts for desired disposal selectively at either side of the railroad track or to a suitable hopper car. The excavator wheel is arranged to drop the excavated material downwardly from the scoops at an upper position onto a subjacent conveyor belt for disposal.

Abstract: An electrical insulating oil comprises a mineral oil and/or an alkylbenzene having a non-basic nitrogen content in an amount of 16 ppm or more, and a basic nitrogen content in an amount of not more than 6% of the non-basic nitrogen content. Preferably the sulfide S content is at least 50 ppm. 
     The mineral oil can be distilled from a crude oil, as a fraction of viscosity 4 to 30 cSt at 40°C, and refined. An alkylbenzene is mono-, di or trialkyl with a side chain alkyl * 9C, of viscosity 5 to 30 cSt and can be a by-product of synthesis of alkylbenzene for a detergent. 
     The insulating oil is produced by mixing mineral oils of different refinery fractions, obtained from crude oil, optionally admixing alkylbenzene, and treating the mixture with clay to remove basic nitrogen compounds; or by adding a non-basic N compound concentrate to a refined mineral oil of low N content.
