Patent number: 4601589Abstract: An electrical thermometer having a digital display comprises a flat, rectangular casing a principal face of which is provided with the digital indicating device, and a measuring probe which is connected with a voltage-fed electrical building block of an electronic analyzer and display unit. The thermometer is devised to be smaller and more compact than known devices and affords a safe operation even under disadvantageous environmental conditions. To this end, the voltage source of the electronic analyzer and display unit block is a solar cell arranged in a principal face of the casing. The presence of this solar cell affords a particularly advantageous permanent guarantee of the energy supply. Moreover, it offers the advantage of a construction of the thermometer casing which is free from the need for a receptacle opening for a battery and can thus be manufactured water-tight in a simple manner.Type: GrantFiled: May 21, 1985Date of Patent: July 22, 1986Assignee: Fa. Diehl GmbH & Co.Inventor: Alfred Meisner

Patent number: 4222010Abstract: In an electronic digital display control device, a pulse generator is actuated to produce pulses which are fed into a counter to control the setting on the display. A discriminator detects whether the frequency of the pulses exceeds a predetermined frequency limit. If the limit is exceeded, the discriminator connects to the counter a second pulse generator which provides pulses at a freqency higher than the predetermined frequency limit. By so doing, the counter receives a substantially greater number of control pulses per unit of time and sets the digital display very rapidly.Type: GrantFiled: June 2, 1978Date of Patent: September 9, 1980Assignee: Firma DIEHLInventors: Alfred Meisner, Werner Arnold

Patent number: 4180087Abstract: A switching arrangement for the control of an adjustable member such as a valve includes a light sensitive switch. Detection of a particular light value enables a frequency divider to transmit an opening pulse to a valve control circuit a predetermined delay period after the detection of such light value. The frequency of an output signal of a pulse generator is varied in response to the opening pulse and the frequency divider transmits a closing pulse to the control circuit after a second predetermined time period of different duration from the delay period. In one disclosed embodiment, control of the frequency divider is responsive to moisture content of soil as well as ambient light level for application in automatic sprinkler systems.Type: GrantFiled: July 21, 1977Date of Patent: December 25, 1979Assignee: Firma DIEHLInventors: Alfred Meisner, Erich Gerum

Patent number: 4091612Abstract: An adjusting mechanism is disclosed for adjusting a digital indicator of an electronic mechanism, such as a timepiece, which includes a first pulse generating mechanism for normally operating the digital display indicator. A second pulse generator includes a pulse former connected electrically to the digital indicator for supplying electrical adjusting pulses thereto. A sensor is operably connected to the pulse former to deliver activating signals thereto for the production of an adjusting pulse. A pulse control member is operably associated with the sensor to control the delivery of activating signals to the pulse former. Either the sensor or the pulse control member is rotatable relative to the other such that activating signals are generated in response to such relative rotation and are generated at a rate which is proportional to the rotational speed of the pulse control member.Type: GrantFiled: September 3, 1976Date of Patent: May 30, 1978Assignee: Firma DIEHLInventors: Alfred Meisner, Werner Arnold, Peter Ennen

Patent number: 3950939Abstract: A twenty-four hour digital display in which the numerals for the display are carried by a 1-hour barrel and a 10-hour barrel which are stepped by a stepping device. A steppable visor driven in steps by the 10-hour barrel covers part of the time the 1-hour barrel which has a function of the time display. The visor itself carries numerals for indicating single-digit hours. The stepping device includes a gearing and a shaft which serves simultaneously as a locking device for the two barrels.Type: GrantFiled: February 6, 1975Date of Patent: April 20, 1976Assignee: DIEHLInventors: Alfred Meisner, Oskar Oellig, Josef Neubauer, Walter Trimpler, Erwin Potthof
