Inventor: MOEHLMANN WILLEM M M
IPC: C11D10/02
Filed: 1986-11-03
Granted: 1991-09-24
Abstract: ABSTRACT OF DISCLOSURE      The present invention relates to a non-aqueous built liquid  detergent  composition  on  the  basis  of  nonionic detergent surfactants and builders.   By using particular nonionic detergent surfactants, which contain ethylene oxide and propylene oxide in a molar ratio of 1:17 to 2:1 (propylene oxide to ethylene oxide) instead of the known ethylene oxide condensation  products,  the  rate  of  dissolution  of  the composition in the wash liquor is substantially improved.          Furthermore,  a low temperature bleach activator such as tetraacetylethylenediamine is substantially much more stable in compositions containing the particular nonionic detergent surfactant than in compositions on the basis of the well-known ethylene oxide type nonionic detergent surfactants.

Title: Process for increasing the energy input in electric arc furnaces
Inventor: BROTZMANN KARL
IPC: C21C5/52
Filed: 1987-08-26
Granted: 1993-07-20
Abstract: ABSTRACT    To save energy in the production of steel in an electric arc furnace while increasing the total input of energy the employment of carbonaceous fuels and oxygen-containing gases is proposed.  The oxygen or the oxygen-containing gases are led into the furnace in the upper part of the furnace through stationary top blowing devices (4) into the space between the pitch circle of the electrodes (10) and the furnace wall (3). The resulting intense gas flow repeatedly sucks in the reaction gases arising from the scrap or the melt being formed and burns them.  The heat thus set free is transferred to the scrap and/or the melt with a thermal efficiency of at least 70%.  By means of nozzles (Z) arranged below the surface of the bath, and preferably in the furnace floor, preferably oxidizing gases are led into the melt and solid materials, particularly carbonaceous fuels, are supplied to the melt through one or more hollow electrodes (6) with an abrasion-resistant cladding.  With this process increased energy input into the electric arc furnace becomes possible, and thus the melting down time can be shortened and the economy of the process improved.

Abstract: EXTRACORPOREAL REMOVAL OF IMMUNOGLOBULIN-G      AND CIRCULATING IMMUNE COMPLEXES        Abstract of the Disclosure A method for removing immunoglobulin-G and immune complexes from blood comprises withdrawing a small, discrete volume of blood from a patient, separating the blood volume into its cellular and plasma components, immediately reinfusing the cellular components to the patient, passing the plasma components through a protein A immunoadsorbent, and reinfusing the treated plasma to the patient.  By treating relatively small volumes of blood and employing an inert, non-colloidal protein A immunoadsorbent, typically protein A covalently bound to microcrystalline silica, greatly reduced side effects are observed without loss of efficacy.  In treatment of cancer and autoimmune diseases, the treatment protocol is repeated periodically, usually at least once per week for a period of four weeks or longer.

Abstract: LINE DELAY COMPENSATION FOR DIGITAL TRANSMISSION SYSTEMS UTILIZING LOW POWER LINE DRIVERS            Abstract:     In a data transmission system including a central subsystem coupled by transmission lines of different lengths to a plurality of remote subsystems, methods and apparatus for synchronizing responses to messages trans-mitted by the central subsystem to compensate for differ-ent line delays are provided.  The messages are trans-mitted by the central subsystem during the first portion of a frame, while the responses are transmitted by the remote subsystems during a second portion of the frame. In each of the remote subsystems, a compensation delay equal to a maximum line delay associated with the longest of the transmission lines less an actual line delay associated with the transmission line connected to that remote subsystem is determined.  The response to the message is then delayed by the compensation delay so that the responses from each remote subsystem arrive at the central subsystem delayed by the maximum time delay.  The central subsystem detects the response during a detection internal delayed by the maximum time delay after the end of the message.

Abstract: ABSTRACT OF THE DISCLOSURE         In a fine access for an optical disk drive, wherein a multi-track jump method is utilized, it is desired that the access method covers a wide range of more than a few hundred tracks with a high speed.  According to the present invention, a one-shot accelerating or decelerating pulse of a short width is sent to an actuator head immediately after every half track pitch travel of the actuator head.  Thus, the actuator head is accelerated when the travel time for a half track pitch is slower than the first reference time and it is decelerated when the travel time is faster than the second reference time.  When the travel time is between the first and second reference times, no pulse is sent to the actuator head.  Thus the velocity of the actuator head is compensated and maintained within a specified range of deviation for a whole long range of jumping many tracks.
