Abstract: For a network composed of a plurality of compensated current switch emitter-follower logic circuits, a generator (31, 32, 33) of a current source control potential (Vcs) for the current sources of the logic circuits is provided so that a symmetrical relationship between UP and DOWN logic levels is maintained at all times. A logic level tracking signal (V R ') which tracks changes in the UP and DOWN logic levels in the logic circuits is produced by circuitry (31) simulating at least a portion of one of the logic circuits. The logic level tracking signal is compared with the reference potential (V R ) used for the logic levels, preferably ground, by a differential amplifier (32). The output of the differential amplifier is buffered and suitably level shifted in a final stage (33) of the generator to produce the current source control potential (Vcs). The current source control potential is applied from the single control potential generator to each of the logic circuits. it is also applied to the control input of a current source portion (41,42) of the simulating circuit (31).

Abstract: 1. Process for the sterilization of preserved food by heating in an autoclave, in which the summed-up F value is electronically detected from core temperature values measured at settable time intervals, and a control signal is generated upon attachment of a settable set-point F value relevant to the particular preserved food, characterized in that - the set-point F value is the set-point value of the total F value, - if the settable set-point value of the core temperature specific to the preserved food is attained or exceeded, at least one further control signal (S2 ) is generated, - the control signals (S1 , S2 ) effect both the automatic shutoff of the food preserving system and the removal of the hot water from the autoclave (2) as well as the delivery of cool water, and - if the core temperature attains the set-point core temperature or drops below it when the preserved food (1) is cooled down, an acoustical and/or optical warning signal is tripped.

Abstract: A method of decreasing HC and CO contained in exhaust gas of an internal combustion engine, particularly an automotive gasoline engine, operated with a very lean mixture by contact of the exhaust gas in hot state with a monolithic catalyst comprising a monolithic carrier, which is provided with an active alumina base coating containing Ce or La in oxide form, and metallic Pd and/or Pt deposited on the coating. The total content of Pd and/or Pt in the catalyst is limited within the range from 0.043 to 0.43 wt%. It is suitable to form the coating by treating the monolithic carrier with a slurry containing a mixture of an active alumina powder containing 1-5 wt% of Ce or La and a powder of Ce0 2  or La 2 O 3  and baking the treated carrier, adjusting the amount of the ceria or lanthana powder such that Ce or La of this powder amounts to 5-50 wt% of the coating after baking. Despite the use of a relatively small quantity of the noble metal, high conversions of HC and CO are achieved even at relatively low exhaust gas temperatures.

Abstract: The novel material consists of water and of cement and paper particles approximately in a weight ratio of 750:100; it is produced very simply by mixing in this order. The paper particles have a size of about 1/2 cm<2>. After drying and setting of the mixture, the material shows surprisingly good strength properties which are, for example in plate form, better than those of the known asbestos boards. It also has a very low thermoconductivity and is equally pervious to air as natural building materials. It is therefore not only suitable as an asbestos substitute, but also for widespread use in the building trade, for example for wall and ceiling elements and other load- bearing components, and also for refractory or heat-insulating parts in other fields of application, in the ceramics industry in place of porcelain or stoneware, for sculptures and as a semifinished product for subsequent machining.

Durch enge Kopplung einer der Einzelspulen (5) mit einer Kurzschlußspule (7) wird ein unterschiedliches elektrisches Verhalten für langsame und schnelle Änderungen der den Spulenstrom treibenden Spannung u erreicht. Bei langsamen Änderungen der Spannung u ergibt sich eine aus der gesamten Spulendurchflutung resultierende Magnetkraft. Bei schnellen Änderungen der treibenden Spannung u führt eine dynamische Verringerung der wirksamen Spuleninduktivität zu schnellen Strom- und Kraftänderungen.
