Title: Radio frequency transmitter
Inventor: DJAMSHIDPOUR MASSOUD DIPL ING
IPC: H03C3/09
Filed: 1982-04-15
Abstract: In a transmitter for the transmission of low-frequency signals (telephony, audio frequencies) in which an RF carrier is modulated with these signals in the myriametric wave range, the object is to operate with a high-stability carrier frequency within a wide temperature range and supply voltage range where a slight adjustment of the carrier frequency is desirable. This is achieved by supplying low-frequency signals (UNF) along with the output signals (U@) of a phase discriminator (2), downstream of which a low-pass filter (3) is connected, to a modulator (1) in the form of a timer (precision Schmitt trigger) which is RC-connected and which operates as an oscillator, where the frequency (fQ) of a high-stability crystal oscillator (4) and the output frequency (fn) of the modulator are supplied to the phase discriminator (2), their phase angles in relation to one another are compared there and an output signal (U@) whose duration corresponds to the phase difference (@) and whose amplitude corresponds to the sign of the phase difference is generated. <IMAGE>

Patent DE-3222893-A1 (DE)
Title: Pressure control valve
Inventor: KUBACH HANS DIPL ING
IPC: F16K31/08
Filed: 1982-06-18
Abstract: A pressure control valve is proposed having a baffle plate which is used for controlling a specific pressure drop. The pressure control valve comprises an armature (85) which lies in an electromagnetic field produced by an electromagnet coil (99) and in a permanent-magnet field, and is supported such that it can pivot between in each case two pole shoes (90, 91, 94, 95) which are provided on both sides of the armature (85). In this case, the pole shoes (90, 91) have opposite magnetic polarity, caused by the permanent magnet (101), to the pole shoes (94, 95) on the other side of the armature (85). The pole shoes (91,94) which are arranged opposite but not aligned on the armature (85) have a reduction in cross-section (104) in order to limit the magnetic flux. In addition, the pole shoes (91, 94) have larger air gap surfaces (106, 107) than the pole shoes (90, 95), smaller air gaps (92, 98) being provided on the pole shoes (90, 95). Arranged between the yoke (100) and the guide body (102) of the yoke (103) is a magnetic conductor (112) whose saturation induction decreases with temperature so that more permanent-magnet flux is short-circuited at low temperature than at high temperature. <IMAGE>

Title: Steam generator with vertical firing chamber and horizontal contact flue
Inventor: PACZKOWSKI KLAUS VON DR ING
IPC: F23H15/00
Filed: 1982-08-25
Abstract: Steam generators which are self-supporting are increasingly demanded because of their advantages. In steam generators, which have a vertically extending, relatively high firing chamber and a horizontal contact flue adjoining in the upper part of the firing chamber, certain difficulties arise for a self-supporting type of construction, since different expansion conditions result for the two heating surface flues. According to the invention, it is proposed to design the contact heating surface as a self-supporting system with a support surface just below this contact heating surface and to arrange the lower part of the firing chamber suspended from this support surface. The invention is advantageous in those steam generators whose heating surfaces are to be cleaned by rapping or jarring, for example in steam generators with refuse firing or other steam generators which have to cope with dust-containing gases.
