Title: Quartz crystal resonator adjustment - involves altering mass at two small areas near edge of resonator without changing size
Inventor: CHOFFAT HUBERT
IPC: H03H9/02
Filed: 1978-06-26
Abstract: The quartz-crystal resonator has its frequency adjusted by altering its mass in at least one region having a small area compared to the total surface of the resonator. The region altered may lie at the edge of the resonator or close to it such that the temp. coefficient of the resonator's resonant frequency is changed without altering the dimensions of the resonator. Adjustment of the resonator takes place in two stages. First the resonator's mass is altered such that the temp. coefficient of the first order of the resonant frequency is zero. Then the mass is altered in a different place such that the resonant frequency is altered but not the thermal properties of the resonator.

Patent DE-2914323-A1 (DE)
Inventor: UNTERWEGER HEINZ DIPL ING
IPC: H02H3/06
Filed: 1979-04-09
Abstract: When the contactor is switched on and the supply voltage (UN) is present, a capacitor (C5) of a control circuit (10) is charged via a first and a second monitoring circuit (8, 9). In the event of the supply voltage (UN) failing, this capacitor (C5) is disconnected from the first monitoring circuit (8) and is discharged via a potentiometer (R9), a resistor (R10) and a diode (D6). When the supply voltage (UN) returns, the voltage across the capacitor (C5) is compared with a reference value, by means of a voltage comparator (16). If this voltage is greater than this reference value, then the voltage comparator (16) produces an output signal which causes a transistor (T3), which is connected in series with the coil of a relay (K), to switch on. This results in the relay (K) pulling in and its output contact (k) to switch over. The contactor is switched on again by the latter. During the failure of the supply voltage (UN), the correct functional sequence is thus maintained by the discharging of the capacitor (C5). External supply sources, such as battery buffers or storage capacitors, are thus unnecessary. <IMAGE>
