Abstract: ABSTRACT:         "Office system comprising terminals, a data processor and auxiliary apparatus and a switching device for mass data transport between the auxiliary apparatuses."          For the updating of document-wise organized in-formation an office system comprises a number of auxiliary apparatuses (20-38) for the recording, filing and out-putting of such informcation. Also present are a processor (52) with terminals (68, 70, 72), peripheral apparatuses (74, 78) and a data bus (67). For the fast execution of mass data transport between the auxiliary apparatuses there is provided a switching device ( 40 ) which comprises a number of parallel data highways (42, 44). Each auxiliary apparatus is connected to the switching module by means of its own switching module (106) in order that it can be connected to either the data bus or, via one of the data highways, to another auxiliary apparatus.

Abstract: METHOD FOR PRODUCING ORIENTED SILICON STEEL HAVING   IMPROVED MAGNETIC PROPERTIES                Abstract of the Disclosure An improvement in the manufacture of oriented silicon steel to improve the magnetic properties, and specifically to achieve improved core loss; the improvement comprises removing at least 3.3µ? from each surface of said steel and normalizing said steel to effect decarburization prior to final texture annealing.     * * * * *           Oriented silicon steel in the form of sheets is known for use in various electrical applications, including the manufacture of transformer cores.  The steel is produced by hot-rolling followed by cold rolling with or without intermediate annealing.  Normalizing treatments are then conducted during which both decarburization and recrystallization are achieved.  The steel is then conventionally coated and texture annealed.  With oriented silicon steel after final texture annealing the alloy is characterized by a secondary recrystallization texture in the (110) [001] position, which is termed the cube-on-edge orientation.  This alloy in sheet form has a single direction of easy magnetization in the direction of rolling.  In applications for this material and specifically when used in the manufacture of transformer cores the material is desirable to have reduced core loss, because the consumption of electrical energy decreases as core loss decreases.

Abstract: SHORT DURATION PTC RESISTOR TIMER Abstract of the Disclosure A short duration timer for use in an electronic circuit such as a diesel engine glow plug control includes a first PTC resistor energized by an electric power source and stabilized in the exponential portion of its resistance-temperature curve.  A second PTC resistor in thermal contact with the first is energized at time zero from the electric power source and substantially immediately stabilizes at a temperature higher than that of the first, resulting in heat flow from the second PTC resistor to the first, and therefore an increase in the resistance of the first, at a rate which is substantially independent of variations in ambient temperature and supply voltage of the electric power source.  A signal ending the time duration is generated when the resistance of the first PTC resistor has changed by a predetermined percentage. In a preferred embodiment, a third PTC resistor having a resistance-temperature characteristic substantially identical with that of the first is at least partially thermally isolated therefrom and connected in electrical series therewith to stabilize similarly.  In this embodiment the end of the time duration is signalled when the resistance ratio of the first and third PTC resistors equals a predetermined value.  The resulting time duration is substantially independent of variations in ambient temperature and supply voltage.

The initializing circuit of the phase-locked loop in the data receiver is inhibited for a predetermined duration upon triggering of a "window mode" by either of a rising or falling pulse-edge in a sequence of "ones" or "zeros" in the received data.  The window mode masks the invalid transitions in such sequences and prevents retriggering by such transitions.

Abstract: MULTIPLE OUTPUT VOLTAGE SWITCHING POWER SUPPLY            Abstract A multi-voltage switching power supply having a first pair of switches connected in series with each other across a pair of incoming power lines.  The switches are alternately closed at a fifty percent duty cycle.  A plurality of pairs of series-connected switches are also connected between the incom-ing power lines and operated in a pulse-width modulated mode. Power supply circuits are connected between the junction of the pulse-width modulated switches of each pair and the junction of the fifty percent duty cycle switches.  The peak value of the current applied to the power supply circuit, which determines the power supply output voltage, is controlled by adjusting the closure time of the pulse-width modulated switches.  However, the pulse-width modulated switches are synchronized to the operation of the fifty percent duty cycle switches so that all correspondingly connected, pulse-width modulated switches are closed only when the fifty percent duty cycle switch connected to the opposite incoming line is closed if the fifty percent duty cycle switches are running. Thus, all pairs of pulse-width modulated switches share the same fifty percent duty cycle switches.  The switches are solid-state devices which inherently have an internal shunt capacitance.  This capacitance allows current to flow through the switch even when the switch is not closed.  As a result, under no-load conditions the output volt-age can rise in an uncontrolled manner.  An uncontrolled in-crease in the output voltage is thus detected and used to alter the operation of the pulse-width modulation control circuitry to cause the pulse-width modulated switches corresponding to that power supply to open and close at the same time as the corre-spondingly connected fifty percent duty cycle switches.  As a result, the voltage applied to the power supply circuit is always zero.

Abstract: ABSTRACT OF THE DISCLOSURE A process is provided for preparing a dry powder microbiological culture medium which can be reconstituted with water and autoclaved to form a clear, pH neutral culture medium capable of supporting the growth of micro-organisms under suitable growth conditions.  The process comprises (a) rais-ing the pH of a dairy whey lactose permeate having a pH below 7 to a selected pH between pH 8 and pH 10 at which essentially all of the dissolved solids which would become insoluble when the permeate is autoclaved for 10-20 min-utes at 121 degrees C and 15 psi precipitate as microcrystalline solids;          (b) separating the supernatant from the resulting precipitate to form a microcrystalline solid  phase consisting essentially of the previously dis-solved solids; (c) removing components having a molecular weight above 100 kdal from the supernatant to form a lactose-rich supernatant which is essentially free of the dissolved solids; and (d) drying the resultant lac-tose-rich supernatant to form the dry powder microbiological culture medium. This dry powder microbiological culture medium is useful itself and as a basic formulation for preparing a wide variety of microbiological culture media.  The precipitate formed is useful as a food grade additive to cause clouding, stabilization, emulsification, and thickening of food, pharmaceuti-cal, cosmetic, and other compositions.
