Title: Part word manipulation in microcomputer systems - is for data switching using part word addressing and positioning and masking device
Inventor: BECHERER CLAUSJUERGEN DIPL ING
IPC: H04Q3/545
Filed: 1978-03-07
Abstract: A circuit is used for manipulating part words in a microcomputer system, esp. a remote data switching unit contg. a central computation and control microprocessor, and an external data store with multiple data locations and data and address channels. It minimises system storage requirements and enhances efficiency. A first positioning and/or masking device in a first multiple data channel between a data store output and the microprocessor separates part words determined by starting and end addresses from data words read from storage and passes them to the microprocessor.

Patent DE-2810470-A1 (DE)
Inventor: AESCHBACHER MANUEL
IPC: B24C5/06
Filed: 1978-03-10
Abstract: The centrifugal device has a fixed control drum (13) and a preaccelerating means (15) which is located in said drum and rotates with, and is firmly connected to, the centrifugal wheel (1). The centrifugal wheel is mounted via flexible elements. Said wheel can thus be displaced, with respect to the fixed control drum, in the radial direction with respect to the control-drum axis (35) in dependence on any unbalance occurring. If the centrifugal blades (10) are then worn down to different extents during operation, an uneven gap (18) appears, due to the unbalance, between control drum and preaccelerating means, as a result of which those centrifugal blades which are worn down to a lesser extent are abraded more severely by the abrasive medium. This control procedure then results in all the centrifugal blades wearing down in a more uniform manner and in their service life being extended. <IMAGE>

Title: Essential amino acids e.g. L-tryptophan sepn. - from derivs. e.g. ester(s) by electrodialysis at ph 4-8
Inventor: PERRY MORDECHAI
IPC: C07D207/32
Filed: 1979-02-26
Abstract: New process is for the sepn. of an aq. soln. mixture by electrodialysis, the soln. mixt. contg. an essential aminoacid and a deriv. of this acid, one component being present in electrically charged form and the other in amphoteric form. Sepn. is into >=2 separate soln. prods. in the form of acid and prod., of which >=1 is obtd. in highly quantitative yield and contains highly pure prod. Through put and concn. of soln., and current density of applied current are adjusted to values which lead to the generation at the membranes of the feed cells concn.-polarisation conditions such that a high local concn. of protons accumulates on the surface of the anion-exchange membrane and a high local concn. of hycroxyl ions accumulates on the surface of the cation-exchange membrane. Independently of the isoelectric point of the aminoacid, the pH of the whole soln. in the feed cells is kept in the range 4-8 in order to equalise pH changes in the whole soln. resulting from inequalities in water decompsn. between the cation a and anion exchanger membranes. Used in sepn. of essential amino acids (useful in human and animal nutrition) such as lysine, tryptophan, histidine, phenylalanine, (iso)leucine, threonine, methionine, valine, or arginine from their derivs. (e.g. esters). The process is esp. useful for the working up of reaction mixts. resulting from optical resolution by stereospecific enzymatic hydrolysis.

Patent DE-3010546-A1 (DE)
Inventor: JUNG MARTIN ING GRAD
IPC: G01S13/58
Filed: 1980-03-19
Abstract: Strictly speaking, the instantaneous speed of an object to be measured, found with the aid of a Doppler radar measurement, represents an average speed of the object to be measured over the measurement time. When the object to be measured is accelerated or decelerated during the measurement time, there can be deviations between the actual instantaneous speed of the object to be measured and the measured speed which are no longer negligible. The deviations occurring in the case of rail brake control in railways are so large that the permissible control inaccuracy of the braking system is reached or exceeded due to this measurement error alone. The invention provides for calculating an actual instantaneous speed (Verw) valid for the time of the respective measurement value determination from the measured speed value (Vm) with determination of the nominal deceleration (-bs) or nominal acceleration (bb) in the brake, which are known in the individual case, and to supply this value, after checking, to the brake control (BST). <IMAGE>
