Title: Transmission circuit with call-up for data processing system - has shift register with processing stage and special and address signals for coded data
IPC: H04L12/12
Filed: 1978-07-27
Abstract: The transmission system uses a detector circuit for a call in a data receiver, where binary coded symbols are being transmitted faithfully. Special symbols will be transmitted automatically when an incorrect symbol is received, and will result in the coded data being retransmitted. The receiver contains a shift register (SR2), which records the received symbols sequentially. There is a processing stage (AS,) where the inputs are connected to the parallel outputs of the shift register. The shift register will cause the processing stage to transmit special signals and address signals under certain conditions. The memory stage will emit a call up signal when the special signals appear consecutively.

Patent NL-8104543-A (NL)
IPC: B23H1/00
Filed: 1981-10-06
Abstract: Method and apparatus for the manufacture of internal or external toothed wheels by spark-erosion [spark-cutting] only, whereby a normalized involute cylindrical toothed wheel, acting as electrode, is unrolled over the workpiece to erode a toothing into the [cylindrical] circumference and/or in the side face[s]. The path of the electrode wheel is controlled during its unrolling motion by a follower-involute tooth wheel running without clearance over a narrow involute-rack bent into a circle and fixed to the machine. A standard high-precision spark erosion machine being used, the feed-control is adapted to hold the workpiece and to have the electrode wheel at each pass sink itself deeper into the material of the workpiece, as function of the momentary to the set sparking-power. The whole width of the teeth is machined in the same operation. The workpiece may consist of hardened or other normally unmachinable material. Especially a <<crown-wheel>>-like involute toothing may be made to co-operate with standard involute pinions, maintaining all known advantages of involute toothings, although the shafts are under any angle, including 90 DEG .

Title: Device for defining the position of an object which can be driven by an electrical drive device with a device for converting slow movement into voltage pulses
IPC: G01D5/12
Filed: 1992-04-02
Abstract: Device for defining the position of an object which can be driven by an electrical drive device with a magnetic device, a closed magnetic circuit, a detection device, an auxiliary power supply device, a control device, an evaluation device and a main power supply device. A drive component of the drive device is connected, e.g. to the magnetic device with play. The magnetic device has a magnetic pole series, while the closed magnetic circuit has a coil and a pole piece series. When, in the event of reciprocal movement at slow speeds, the magnetic device is moved beyond a position in which a pole piece is located opposite a position halfway between two adjacent magnetic poles, a step is made under the influence of the magnetic field and a voltage pulse is generated over the coil. The magnetic device is furthermore provided with a series of areas with different characteristics fixed in position in relation to the magnetic pole series. The detection device comprises detection elements to detect the characteristics of the series of areas. The auxiliary power supply device is connected to the coil to generate a power supply voltage from the voltage pulse. The control device activites the detection elements during the time that the power supply voltage exceeds a defined value. The evaluation device determines the current position of the object from the output signals of the detection device. The main power supply device supplies the drive, detection and evaluation devices. The auxiliary power supply device supplies the detection device and the evaluation device when the magnetic device moves. The evaluation device stores the output signals from the detection device and the current position of the object in a non-volatile memory when the output voltage of both power supply devices falls below a defined value, and retrieves them when the output voltage of at least one of the two power supply devices exceeds the defined value.

Title: Process for the preparation of optically monoesters derivative from alkanolamines and tartaric acid
IPC: C07C219/20
Filed: 1984-08-08
Abstract: For the analytical and preparative separation of the optical isomers of optically active alkanolamines into their optically pure antipodes a new resolution method is presented which involves an ester formation of the alkanolamines with optically pure and symmetrically O,O disubstituted (R,R)- or (S,S)-tartaric acids. The derivitization reactions are carried out in aprotic solvents and the primary and secondary functions are blocked via ion-pair formations with strong acids, e.g. dichloroacetic acid. The tartaric acid anhydrides are predominantly used as reagents but other ester formation methods are also practicable. The mixture of the diastereomeric alkanolamine tartaric acid monoesters are separable into their optically active and pure isomers by various chromotographic separation techniques, e.g. straight or reverse phase LC, but also by extraction methods e.g. Soxhlet extraction. The optically pure parent alkanolamine isomers can be obtained by ester hydrolysis, with high yield, from the optically pure fractions of the alkanolamine tartaric acid monoesters.

Abstract: The present invention relates to a soluble form of intercellular adhesion molecule (sICAM-1) and purified and isolated human sICAM-1. This invention also relates to a purified and isolated DNA sequence encoding sICAM-1. The extracellular domain of sICAM-1 and insoluble ICAM-1 are substantially the same. ICAM-1 is involved in the process through which lymphocytes attach to cellular substrates during inflammation and serves as the major human rhinovirus receptor (HRR). sICAM-1 therefore has both the property of reducing immune inflammation and inhibiting infection of rhinovirus and Coxsackie A virus.
