Patent EP-0276555-A2 (EP)
Inventor: QUARANTI GIOVANNI
IPC: B41J1/24
Filed: 1987-12-09
Abstract: The correction device (12) is applied to an electronic typewriter and a daisywheel (27) and comprising an electric selector motor (28) which selectively rotates the character-­carrying daisywheel (27) in the clockwise and the anti-clockwise directions for selecting the characters to be typed and/or corrected, a carrier (36) for a correcting ribbon and a control member (56) for lifting the carrier (36) and permitting correction of the typed characters. A small correcting solenoid (63) can be activated to couple the control member (56) of the correcting ribbon to the selector motor (28). The control unit controls the motor (28) and the solenoid (63) in such a way that the selector motor (28) can also actuate the control member (56) in each correction cycle for positioning the correcting ribbon in front of the typing point. In the illustrated form, the solenoid (63) unlatches a lever (46) which drops to bring the control member (gear 56) into mesh with a gear (67) on the motor shaft (29). The control gear (56) is eccentrically mounted on the lever (46) and a first 180° revolution, corresponding to 360° revolution of the daisywheel (27) raises the lever (46) and carrier (36) to correcting ribbon height which a subsequent 180° rotation drops the carrier (36) back to typing ribbon height with the lever (46) latched by the solenoid armature (62).

Abstract: A line driver circuit capable of operating at high speeds. The output transistor (Q₁₄), an emitter con­nected to an output terminal (17), has a special feedback capacitor (C₁) connected to its base. The feedback capacitor helps pull the output terminal high to increase the switching speed of the line driver cir­cuit. Special current injection and removal techniques are used to speed the switching times of the PNP current supply transistors (36, Q₁₇). The line driver circuit also has special circuitry (14) to limit the output current from exceeding certain limits and for keeping the line driver circuit from overheating.

Abstract: Disclosed is a vacuum tube type collection device for collecting blood or other body fluids from a patient. The device includes a conventional sealed vacuum tube (12) received in a tube holder (14) having a removable needle assembly (16) connected to the tube holder. The characterizing feature of the device of this invention is that the needle assembly has a guard member (70) which protects the exposed tip of the needle after withdrawal of the needle from the patient's body. This member is movable between a first position where the tip of the needle is exposed and a second position where the guard member covers the tip of the needle and prevents needle sticks. A locking element is mounted along the needle shaft which permanently locks the guard member in the second position upon movement of the guard member into the second position.

Abstract: A Data Access System for a File Access Processor for servicing requests from a set of Application Support Processors, which can exist in a global network, with each Application Support Processor sharing access to data in files stored by the File Access Processor. The File Access Processor manages access to a set of data files and information about files held in file director­ies, which allow for managing file collections, can relate to each other hierarchically, and may be shared. Each Application Support Processor also maintains therein an internal cache of file information to improve performance by reducing communications required with the File Access Processor for information about files. The File Access Processor provides the Application Support Processors with information for updating and maintenance of local caches of directory and file description information through a centralized accumulation and distribution of cache change notifications. The Data Access System also provides for permanent storage in the form of catalogs for retaining shared information about files, directories, and control information. A separate access method and storage facility is utilized for these catalogs from that utilized for file data, permitting flexibility in access to catalog information which require access only occasionally, while retaining high performance in the access to file data.

Abstract: A liquid detergent composition comprises a surfactant concentrate and a proteolytic enzyme derived from a microorganism: for improved storage stability in the liquid state the proteolytic enzyme is of the proteinase K type. Proteinase K is a known fungal alkaline serine protease from Tritirachium album Limber, and its use in liquid detergent compositions can provide enzymatic liquid detergent with improved enzyme storage stability in comparison with other proteolytic enzymes, thus reducing the amount of enzyme stabilisers usually required for proteolytic enzymes in liquid detergent compositions. Proteinase K also has improved performance in compositions with an increased ionic strength or molarity.

Abstract: In single sideband mixers, which usually consist of two push-pull mixers which are operated with 90 DEG  phase difference at the oscillator and intermediate-frequency connections, the requirements for freedom from sidebands are high. The first oscillator harmonic represents the strongest interference signal in this context. This is particularly problematic if the mixer is followed by an amplifier as, for example, in the case of microwave transmitters. The solutions according to the invention provide for an interconnection of the two push-pull mixers in such a manner that the first oscillator harmonics either cancel or are conducted to a terminating resistance by means of a hybrid T. <IMAGE>
