Title: Ortho:phenol-formaldehyde oligomer prepn. - by reacting crystalline phenol and formaldehyde gas to give phenol-alcohol and condensing
Inventor: AKUTIN MODEST SERGEJEVITSCH
IPC: C08G14/04
Filed: 1976-10-28
Abstract: Ortho-regular phenol-HCHO oligomers are prepd. by (a) reacting (i) comminuted crystalline phenol, or a mixt. contg. crystalline phenol and 14-58 wt. % crystalline naphthalene, with (ii) gaseous HCHO, at 20-40 (20-25) degrees C, to form phenol-alcohols as the prim. prod.; (b) condensing the phenol-alcohols, (c) drying, i.e. removing water of condensation and (d) heat-treating the oligomers prepd. The prods. are used as binders for moulding compns. subjected to high temps., pressures and ionising radiation. Phenol-alcohol prodn. step at crystal-gas interface takes place in an anhydrous medium, without added catalyst, at a low temp. The naphthalene can form a reactive donor-acceptor molecular complex with the phenol. The formation of tar-contg. gas waters is reduced to 7 wt. %. Energy consumption is reduced. Costs of end-prod. can be reduced by 10-13% and costs of plant by 30-50%.

Patent DE-2727975-A1 (DE)
Inventor: RHOMBERG BRUNO CLEMENS
IPC: H03H11/16
Filed: 1977-06-22
Abstract: The phase shifter for the auxiliary signal of the diversity system has a quadrature modulator (6, 7, 8, 9). In a power divider (6), the auxiliary signal is divided into two signals with a 90 DEG  phase difference. Each of these sub-signals is forwarded to a diode modulator (7 or 8) to which modulation signals s(t) and  sigma (t) are applied. The two sub-signals are then vectorially added in a 3dB coupler (9). The modulated auxiliary signal is vectorially added to the main signal in the 3dB coupler (11). This electronic phase shifter can replace a motor-driven rotating phase shifter in a space diversity system designed along conventional lines. In a matching circuit (15), the conventional DC voltage phase correction signal n(t) is converted into the modulation signals s(t) and  sigma (t). In the circuit (15), the signal n(t) is first converted into a pulse signal. The pulses are then counted in an up-down counter, the counter reading in each case corresponding to the instantaneously required phase shift. The parallel output of the counter passes to two read-only memories which are programmed in such a way that a cosine or sine function is simulated. The output signals of the memories are applied to digital-analog converters at whose outputs the modulation signals s(t) and  sigma (t) appear. <IMAGE>
