Title: Ac level calibration method and apparatus
IPC: G01R35/00
Filed: 1987-04-08
Granted: 1992-02-19
Abstract: In an analog test system for testing integrated circuit chips, AC level calibration is achieved by adding a minimal number of new elements and more fully utilizing elements existing in the system. A reference voltage from an existing precision DC power source is fed to an analog switching device. A control signal is also fed into the analog switching device from an existing digital signal generator. Based on the control signal, the analog switching device converts the reference voltage into a rectangular waveform signal, which is then digitized. The digital signal is analyzed, and data from the digital signal is compared with reference data, and the AC level error, if any, is determined. AC level calibration is based on this error.
Patent EP-0258621-B1 (EP)
IPC: H03M13/00
Filed: 1987-07-27
Granted: 1993-10-06
Abstract: The transmitter in a digital communication system sends a synchronization sequence that uniquely identifies the polarity of the received data. From the received data (418), the receiver produces non-inverted and inverted polarity data streams (358, 358') that couple to like synchronization detectors (200, 200'). Only the detector to which the correct polarity data stream is coupled responds. Logic circuitry determines which detector responds and, accordingly, selects the polarity of received data to be further processed by the receiver (422). After polarity is established (60), both detectors monitor the received data stream of the selected polarity to determine whether synchronization shifts after having been initially established. Monitoring continues until terminated by other receiver circuits.

Granted: 1991-12-18
Abstract: The method for the manufacture of brushes consists in that bristles made of plastic individual bristles or lines of bristle are introduced through channels and sleeves, extending said channels, into a mould for the brush bearer, are thermally melted at their end, situated at the mould, to form a thickening and the thickening, produced during the melting process, at the bristle ends is then brought into sealing contact with the orifice of the sleeve projecting into the mould. While the mould is being filled, the bristles and the sleeve are kept in their position inside said mould and the sleeve and the thickening at the bristle ends, resting tightly against the orifice of said sleeve, are enveloped by the bristle bearer material while the mould is being filled, after which the sleeve is removed from the bristle bearer.

Abstract: The syringe is intended for medical use and is provided, for this purpose, with a syringe barrel (2) designed at one end for attachment of an injection needle (1) and with a syringe plunger (3) displaceable in the syringe barrel (2). The syringe plunger (3) sits axially securely on a plunger rod (4), which protrudes from the syringe barrel (2) at the cylinder end opposite the needle attachment end (5). In addition, a second syringe plunger (6) is provided, which is arranged, likewise displaceably, between the needle attachment end (5) and the syringe plunger (3) sitting on the plunger rod (4) and thus forms a two-chamber syringe. Provided in the wall of the syringe barrel (2) is a bulge, which is directed radially outwards and forms a bypass (9), via which bulge the two chambers (7, 8) are connected to one another when the second syringe plunger (6) is in the area of the bulge. Arranged at the cylinder end opposite the needle attachment end (5) is a damping part (10), which serves as a plunger brake and which, in the event of the syringe barrel (3) shifting by means of the plunger rod (4) in the direction of the needle attachment end (5), permits initially only a slight lifting speed of the plunger (4) as long as the syringe plunger (3) sitting on the plunger rod (4) has not reached the area of the bypass (9). <IMAGE>

Granted: 1996-03-27
Abstract: A process is described by means of which it is possible to prepare stable, basic calcium carbonate of determinable crystal structure on a large industrial scale. The process according to the invention is distinguished by the fact that an aqueous suspension of calcium hydroxide is carbonatised by addition of CO2, defined temperatures of the suspension in the range from 2 to 50 DEG C are maintained during this carbonatisation, and the carbonatisation is then completed at a molar calcium carbonate ratio of 3 : 2 or 6 : 5. Depending on the initial temperature of the suspension, platelet-like, rod-like or fibrous calcium carbonate, calcium carbonate of somatoidal crystal form or even basic calcium carbonate having comparatively large rhombohedra are obtained. The products obtained by the process according to the invention, to which the invention is also directed, are, owing to their structure, suitable in particular for the use in paper production, for emulsion paints, fillers for plastics, rubber, synthetic resins, etc. <IMAGE>
