Granted: 1986-10-02
Abstract: Process for producing flexible PVC irrigation pipe by extruding a plasticised PVC composition containing a melt strength-enhancing aid and a chemical blowing agent and (a) the extruded melt being expanded by foaming thereof immediately on leaving the die into a substantially closed-cell extrudate of outer diameter greater than the die orifice with the extrudate surfaces being substantially unpunctured, (b) drawing down the extrudate in the atmosphere causing rupturing of the foam cell walls of the extrudate to form a substantially open-cell extrudate having punctured surfaces, and (c) when the extrudate has been drawn down to a degree which is prior to any cellular collapse which would lead to the formation of water-impervious pipe, cooling the extrudate by passing it through a cooling means in order to prevent said collapse. Preferably the extrudate passes through a tubular guide into a water bath in step (c). The pipe thus produced is suitable for irrigation applications and may be used for long periods without exhibiting an unacceptable decrease in water-permeability.

Title: Device for counting flat products moving over a conveyor path
Inventor: HONEGGER WERNER
IPC: B41F33/02
Filed: 1982-11-04
Granted: 1987-11-19
Abstract: A product counter apparatus is disclosed comprising a support element which bears against the products, typically printed products, which are to be counted. A holder device is mounted at the support element. Secured to such holder device is a substantially L-shaped spring or resilient element containing two leg members. The one leg member of such resilient or spring element extends substantially transversely with respect to a predetermined conveying direction of the printed products and protrudes by means of its free end past the holder device. The other leg member of the resilient or spring element is clamped at its end, and thus, can be elastically deflected transversely to a plane containing the printed products. Retained in the holder device is an inductive proximity switch. The printed products moving past the counter apparatus impact at their leading edge at the end of the one leg member which serves as a feeler or sensor and deflect the latter in their product conveying direction. At the same time the feeler is raised while there is deflected the other leg member of the resilient or spring element. Consequently, it is possible for the feeler to be released from the printed product engaging thereat and to resiliently return back into its starting position. During approach of the feeler at the proximity switch the latter generates a counting signal which is inputted to a counter mechanism.

Title: Data in- and output device for a drive control device operated by a digital computer
Inventor: KINDLER GERHARD
IPC: B66B1/28
Filed: 1983-12-02
Granted: 1987-01-22
Abstract: The data input/output device of an elevator drive regulation receives actual values of the speed and of the displacement of an elevator cabin at related counters which are connected to related digital tachometers. The data are evaluated and transmitted via an interface to a digital computer of the drive regulation. The digital computer compares the data with stored reference values and computes input values for related adjusting members of the drive regulation. The computed input values are transmitted via the interface to and stored in a programmable multiple counter of the data input/output device. The programmable multiple counter contains three counters each of which is connected through a driver stage with a thyristor associated with one phase of a three-phase a.c.-elevator drive. A synchronizing device ensures that all thyristors are always ignited at any one time at the same phase angle which corresponds to the adjusting magnitude. A further counter of the programmable multiple counter is connected to a driver stage which acts upon the control of an eddy-current brake in the drive regulation.

Title: Method of regulating a thermal installation
Inventor: HUBER JAKOB
IPC: G01K17/06
Filed: 1984-12-14
Granted: 1988-05-26
Abstract: A process controlling a thermal installation is described. The flow of a process liquid through a heat exchanger is achieved dependent upon two temperatures. One is the return temperature of the process liquid which, through the switching on and off or modulation of a circulation pump is maintained at a constant value. The other is the room or outside temperatures or the difference between these two temperatures, whereby during the deviation of a predeterminable limiting value the pump is also switched on and off or modulated. Since the supply temperature from a boiler has a constant temperature, for a central heating system the same amount of heat is drawn from each unit of heating water and thus the measure of the pump flow is sufficient to determine the actual heat consumption. Thereby the fair division of heating costs for each tenant according to actual amount consumed is made possible.

Granted: 1993-06-17
Abstract: The present device provides a downstream magnetic shield which is integrally formed with a write pole section having a tip to make up a magnetic recording head. The shield and the write pole tip are located with small gap therebetween, so that magnetic flux which fringes from the magnetic write pole tip is intercepted by the shield. Accordingly such fringing flux does not pass through the recording medium, and hence if a data bit has been written into the recording medium its dipole identity will not be weakened by the fringing flux of a subsequent data bit being written into the magnetic recording medium. In addition, the magnetic recording medium is made up of a first layer of material having perpendicular uniaxial anisotropy and an underlying layer made of a material which has a low magnetic flux reluctance characteristic. Accordingly, the magnetic flux passes vertically through the first layer, along the second layer and finally passes vertically from the second layer through the first layer into the shield. The face of the shield is designed to be many times as large as the face of the write pole section so that the density of the flux from the tip is sufficient to effect a vertical recording while the density of the flux passing into the downstream magnetic shield is low and hence a previously recorded pattern is not reversed.

Abstract: To achieve the desired effect in the final colour print produced from printing plates using colour-subtractive inks, it is necessary to modify the dot-size in some areas of the original halftone colour separation print.  The change in dot size is achieved by exposing the print in contact with an isolation mask, which has the required dot pattern in the areas concerned but protects the rest of the picture from over-exposure. The isolation mask is prepared by editing a dot mask file to suit the changes required and then transferring the resulting pattern to photographic film by scanning laser.

Abstract: A high accuracy power meter capable of measuring power supplied or consumed in multiple phases of a distribution system is fabricated as an integrated circuit. Voltage and current sensing transducers coupled to the power meter provide input signals having a potential proportional to the voltage and current in the distribution system. A low charge injection pulse width amplitude multiplier using a digitally-synthesized triangular wave is provided for each phase. Each multiplier receives the input signals and provides an output signal having a current proportional to the product of voltage and current in that phase of the distribution system. Charge from the multiplier output currents for all phases is accumulated in a capacitor connected across an autozeroing amplifier, which corrects for its own offset voltage. The amplifier output controls a switch connected between a reference potential and the capacitor. When the switch is closed a reference current is supplied to the accumulating capacitor to balance the charge from the multiplier for each phase. The frequency of the switch control signal provides a highly accurate measure of the power consumed or supplied by the distribution system.
