Abstract: A method of and apparatus for peeling potatoes by bringing the potatoes (11) into contact with at least two rotating grinding rolls (3) subjecting the potatoes to a grinding effect removing the peel. In order to be able to effect the peeling under dry conditions, the peeling is carried out without introduction of water into the peeling area and the grinding rolls are cuased to rotate at a rate such that the ceentrifugal force throws away the peelings (14′) from the surface of the grinding rolls. The peeling machine is proveded with a driving motor (7) which is able to rotate all the grinding rolls (31 at a rate of rotation sufficiently high for causing the peelings to be thrown away.

Abstract: In order considerably to improve the combustion during the operating time of smaller ventilator burners also, in particular one or two-stage ventilator burners, with reasonable outlay, as the main deregulating factors the pressure (pL) and temperature ( theta L) of the combustion air are measured and from these, on a compensator (25), a simple compensation function is determined, with which, on a superposition unit (27), action is taken on the combustion air flow (L<*>) and/or on the fuel flow (B<*>). Precisely in said burners, the greater part by far of the influence of deregulating factors stems from said main deregulating factors.

Abstract: A fast packet switching system comprises an interconnection network associated with a distributed control structure composed of a plurality of processing units (UC1-1 ... UC3-16) managing the routing at the virtual call level. At least some of said processing units associated each with a group of network inputs/outputs store bandwidth occupancy data relevant to the interstage links which can be reached from the inputs of said group and are included between said inputs and a central network stage where there is a maximum number of alternative paths or, respectively, bandwidth occupancy data relevant to interstage links which lead to the outputs of said group and are included between said stage and the output, said data being updated whenever a new call is routed. 
     When a virtual call is to be routed, the processing units associated with the input or respectively the output involved in the connection, evaluate each, on the basis of the up-to-date conditions of bandwidth occupancy and of the bandwidth requirements of the new call, a cost function of the connection along the portion of each of the possible routing paths included between the input and the stage where there is the maximum number of alternative paths, or respectively for the portion of each routing path included between such stage and the output; the results of the evaluations carried out by said units are combined together in one of the units which determined a global cost function for the individual connection paths and forwards the call on the path presenting the minimum cost function.

Abstract: To inject samples into a mass spectrometer, one end of a capillary tube is affixed directly to the vacuum chamber of the mass spectrometer or to a mass spectrometer interface to bring gaseous samples into close proximity to the mass spectrometer ionizing means, and the other end is in close proximity to the surface of a tape. The tape is in a cassette and a probe is inserted through the cassette frame between the cassette reels and draws the tape to the end of a capillary tube. Regions of tape with samples adsorbed to tape surface are transported rapidly from a low temperature region for a high temperature region which includes the entrance end of the capillary tube. Sample vaporizes from the tape surface and is carried into the capillary tube by a carrier gas. The tape position is indicated by bar codes on the tape that control tape movement.

Abstract: Alignment difficulties in optical computing arrangements are overcome by integrating a number of the optical components on a single substrate and arranging the elements in a manner that causes them to interact with one another to perform the desired functions, such as image manipulations. The substrate has one or two major surfaces and the elements are fabricated on those surfaces using conventional integrated circuit manufacturing techniques. Most advantageously, the position-sensitive optical devices are manufactured on one side of the substrate, obviating the need to align two masks during the manufacturing process.

Abstract: A computer system with a number of subsystems or modules on separate circuit boards employs electronic keying to ensure proper configuration of these boards. A power key arrangement associated with a plug-in connector enables a separate power supply for each set of boards. A power supply turn-on signal is routed through a uniquely-configured connector path for each board, so the power supply turn-on is inhibited for improper configurations. The uniquely-configured connector path may use either a series or a parallel implementation. The series implementation employs a set of diodes connected for conduction in either of two directions, with the mating connector having its conductor paths connected to match the diode configuration; in this manner, the power supply enable signal can only flow through the series path if the proper board is plugged into a properly-coded slot, in which case the power supply to activate this board is activated through the series path including the diodes. The parallel implementation employs a given number of connector pins to establish the coding for each board, and each pin is either open-circuited or connected to ground; if this coding of the subsystem board is not the same as that of the slot into which it is plugged then the power supply activation signal will be shorted to ground by one or the other of the coded pins.

Abstract: Integratable transistor circuits for outputting logic levels generally consist of the actual switching stage (S) and a switching stage output current amplifier (V) used for increasing fan-out. The lower the current flowing in the switching stage and the greater the value of the resistor (R1) determining the achievable voltage swing, the more the absolute output levels of such circuits depend on the boundary conditions, for example temperature and supply voltage fluctuations. The absolute output voltage levels become largely independent of the boundary conditions by allocating a level monitoring circuit (P) to the switching stage. At the control input of the level monitoring circuit (P), a reference voltage (VB2) is present which fixes the absolute value of one of the two logical output voltage levels. …<IMAGE>…

Abstract: The temperature compensated reference circuit has a first common emitter BJT whose base is connected to a first JFET current source and through a JFET resistor to a voltage output. The JFET resistor is biased in the linear region and the JFET current source is biased in the saturation region in an operating condition. The voltage across the JFET resistor is selected to be approximately equal to the pinch-off voltage of the JFET current source. The temperature co-efficient of the first BJT and JFET resistor will cancel one another to produce a generally temperature invariant voltage at the output. The voltage regulator incorporates the reference circuit and has a second BJT current source driving the reference circuit. A feedback system includes a second JFET current source between the collector of the first BJT and the connection between the voltage output and the collector of the second BJT. The second JFET current source drives the base of a common emitter third BJT. The collector of the third BJT is connected through a resistor to the base of the second BJT. The feedback system regulates the amount of current necessary to drive the reference circuit and the load.
