Title: Frequency divider for GHz range - has amplifying FET synchronised to input frequency and producing wave of selected divided frequency
IPC: H03B5/18
Filed: 1991-10-31
Granted: 1992-09-10
Abstract: The frquency divider (FT) intended for short e.m. waves is equipped with an amplifying FET synchronised to an incoming wave, providing an input frequency (fo) and producing a divided frequency (ft). The input frequency is a whole-number multiple of the divided frequency. This divided frequency can be obtained from a part of the signal on the output (D) of the FET, while the output is also fed back to a first input of the FET through a coupling network (KN1) in such a way that, in the case of the feedback of a wave with the divided frequency, the phase rotation in the FET is complemented to a value of 360 deg. or a whole number multiple of this. A second coupling netowrk (KN2) is connected to the second input (S) of the FET for a connecter-feedback and the incoming wave is fed through this to the FET. USE/ADVANTAGE - Can be used for waves covering wide frequency band. Suitable for communications systems.

Abstract: The reformer (1) includes a measuring device (9) for a control parameter which provides an indication of the amount of heat needed by the reformer from the burner (7). This parameter is used by the control device (10) to regulate the supply (2) of reagents (3) to the reformer. An apparatus comprises a reformer, a hydrogen-consuming process (5), a burner, a controllable supply for the primary reagents for the reformer, and a control device. The hydrogen-consuming process generates a stream of combustible offgas (6) which is burnt in the burner, a large part of the heat (8) generated in the burner being used in the reformer. The reformer includes at least one measuring device for a control parameter which provides an indication of the amount of heat needed by the reformer from the burner. This parameter is then used by the control device to regulate the supply of reagents to the reformer in order to alter the amount of reformate gas (4) being supplied to the hydrogen-consuming process, leading to a change in the amount of exhaust gas being supplied to the burner, so that an optimized amount of heat is supplied to the reformer by the burner. An independent claim is also included for a method for operating the above apparatus.
