Title: Electronic telephone payment indicator - displays total running cost, individual unit and progressive call costs with maximum monitor
Inventor: MENSCHEL WALTER DIPL ING
IPC: H04M15/28
Filed: 1978-11-29
Abstract: The electronic telephone payment indicator can be attached to an existing telephone set or form part of a set. The indicator gives a continuous digital reading of the cost of a telephone call in progress. The cost per unit is inserted in a programmable calculator module. A maximum coil can be inserted and, when the call cost reaches this maximum, a light flashes. The indicator has a quartz controlled clock which indicates the date, time and the relevant cost per unit. The total cost pulses are stored in a counter which is reset by a switch, and the cost pulses for the call in progress are stored in a second counter which is reset at the end of the call.

Title: Roof or facade collector for energy of sun - has fluid circulating pipes embedded in screened wall structure
Inventor: KOESTER HELMUT DIPL ING
IPC: F24J2/04
Filed: 1978-12-02
Abstract: A layout in which fluid circulation tubes are installed behind a roof or facade cladding on the back of which a multi-layered skin with an infrared reflector is provided, is modified. The tubes of the collector element are embedded in a single or multi-layered wall structure, in concrete, in joints between plates or in wall facings the outer surfaces of which have a sawtooth contour. The facade cladding projects outwards and its angle can be adjusted to suit the lowest angle of the radiation of the sun. Arrangement makes the collector system independent of the radiation determined by the weather, and the energy can be withdrawn from that stored in the wall. No additional fluid store s necessary and in summer the wall can be cooled so that heat can be extracted from inside the building.

Title: Sliding window or door fixed wing - is invisibly joined to blind frame by interlocking connectors on top bars
Inventor: MUEHLE MANFRED
IPC: E06B3/46
Filed: 1978-12-02
Abstract: The stationary wing is connected to the blind frame, in the window or door which has one or more sliding wings and one or more stationary ones. The stationary wing (3) and blind frame (2) are rigidly and invisibly interconnected, in the operative position by form-locking interlocking fixture members (25, 30) on their top horizontal bars. These are pref. fastened to these bars (6), with rigid connection achieved by thrusting the fixed wing into its operative position. This simplifies installation of the blind frame in the wall opening, esp. for wide sliding windows or doors.

Title: Electric magnitudes measuring system - involves connection of high resistors to current source and feeding resistor voltages to computer
Inventor: LAUERER FRIEDRICH DIPL ING
IPC: G01R15/12
Filed: 1978-12-20
Abstract: To prevent defective reading of measured values the system provides loading of the current source by differently high resistors in a time sequence. The voltage across the resistors, or at a constant part of them, is directly supplied to a computer, while the desired magnitude is indicated at the computer output. The computer is programmed for various applications by different formulae, e.g. for determining a sinewave a.c. voltage with unknown supply impedance, for determining of a d.c. voltage, or a sinewave a.c. voltage at unknown supply resistance. Another formula is used for determination of a real part of an impedance at unknown sinewave supply a.c. voltage. Still another equation is used for determination of the real part of an impedance with known sinewave supply a.c. voltage, for determination of a reactive part of an impedance at unknown sinewave feed a.c. voltage, and finally for determination of the reactive part of an impedance at known sinewave feed a.c. voltage.

Title: Separating square bottles from continuously fed line - by worms with varying core dia. and increasing pitch either side of conveyor
Inventor: ZEPF GEORG
IPC: B65G47/08
Filed: 1979-05-15
Abstract: The arrangement is intended for incorporation into a labelling machine and consecutively separates individual square bottles (1) which are fed by a conveyor (2) in a continuous line with their sides in mutual contact. The bottles initially move between side rails (3) and then enter between the windings of two synchronously driven transport worms (4, 9) arranged to either side of the conveyor. The worms have corresponding ranges with increasing pitch, and the initial portion of one worm (4) has a gradually increasing core diameter, whilst that of the other one (9) decreases correspondingly so that each bottle is moved sideways and accelerated away from the next following bottle.

Title: Appts. for measuring excretion of urine - using electronic counter to count drips passing phototransistor, giving digital display via binary-decimal converter
Inventor: BROCKMUELLER KAY-DIETER DR MED
IPC: A61B5/20
Filed: 1979-05-22
Abstract: The precise measurement of the amount of urine excreted during a given period is achieved electronically by counting drips during a specified period. The indicator may be remote from the patient. A catheter (10) is linked to a drip chamber (111) which includes an infrared light source (S) and a photosensor (E). The pulses produced by this device are fed to a divider (123) which produces one pulse for every 12 pulses input (12 drips=1 cm3). These pulses drive a counter and binary-to-decimal decoder (124) resulting in a digital indication in a display (133) giving the total amount of urine at any particular moment. A clock generator (121) gives time indication. The clock pulses moreover are gated (125) with the output of the divider (123) to produce cm3 per unit time measurement. Limits may be pre-set which if exceeded give a visual and audible warning.

Abstract: The d.c. motor has a device to generate a moment acting against the attenuating component of the drive moment in order to reduce the fluctuations in the drive moment. The counter-moment has a signal opposing that of the average drive moment and is smaller than the latter moment. The control circuit for the drive current pulses also produces the counter-moment and accordingly has a resistor connecting appropriate connections of the winding groups together. The resistor is large compared to the internal resistance of the winding groups, e.g. 30-70 times greater. The motor receives a constant d.c.
