Patent DE-2620404-A1 (DE)
Inventor: MOYER NORMAN E
IPC: G04G5/00
Filed: 1976-05-08
Abstract: A digital wristwatch with dual displays, one a liquid crystal display (LCD) for use in daylight or bright light and the other a light emitting diode (LED) display for use in dim light, is provided with three controlling push buttons (LED, Date and Set) for five display conditions and four setting conditions. With no button pressed, hours and minutes are displayed by the LCD elements. The LED button alone causes the LED elements to also display the hours and minutes for at least 1.5 seconds and the Date button alone causes the date to appear by the LCD, and if the Date push button is held over about 1.5 seconds the date will also appear on the LED display. The LED and Date buttons pressed together will cause the LCD elements to display the seconds, even after they have been released for "hands off" seconds display until either push button is again momentarily pressed. The Set button slews hours when pressed alone, and slews minutes and instantaneously zeros seconds when pressed together with LED, and slews the date when pressed together with the Date push button. Pressing all three will cause a complete reset of all counters.

Title: Welded tube for HF conductor - uses aluminium strips longitudinally joined at forty five degrees to give spiral end seams on finished conductor
Inventor: ALTHOFF FRIEDHELM
IPC: H01P3/127
Filed: 1976-08-18
Abstract: The outside sheath of the coaxial high frequency conductor is made from an aluminum strip, which for the purpose of shaping a tube is rolled into cylindrical mantle and welded longitudinally. In order to avoid unnecessary material cut offs, the aluminium strips for the continuous production of the cylindrical mantle are joined by a lateral weld at their ends. The ends (1) and (2) of the strip are placed together, held down by clamping jaws (3) onto support (4) and welded together along seam (7). The relevant feature of the design is that this seam is placed at an angle of 45 deg., so that when the strip is rolled into the cylindrical mantle, the lateral seam appears on the mantle surface as a spiral of 45 deg. pitch. If a necessary bend happens to coincide with the seam, the two critical ends of the spiral are far enough apart not to interfere with the bending operation.

Title: Measurement electrical power and energy - with sensing time error compensation using intermediate storage and interpolation
Inventor: MASSEN ROBERT DR ING
IPC: G01R21/133
Filed: 1977-03-09
Abstract: The method is for measuring electrical power and energy by conversion of sensed values of voltage and current into pulses with average values corresp. to the voltage and current levels and involves voltage-current multiplication by logical pulse combination. It is designed considerably to reduce residual sensing time errors using an interpretation circuit and to avoid the disadvantages of h.f. sensing hitherto necessary to reduce such errors. Pulses are held in intermediate digital stores and a switch synchronised with the sensor and a logic combination network used to produce pulses with probability proportional to the interpolated values. Another logic network produces pulses with probability proportional to the interpolated and non-interpolated pulse product.
