Title: Receiver for frequency-shift-keyed RF signals
Inventor: DJAMSHIDPOUR MASSOUD DIPL ING
IPC: H04L27/148
Filed: 1987-01-08
Abstract: In this receiver, in which each frequency represents one of two binary states of a binary coded message, it is intended to provide for an increase in the transmission speed while simultaneously reducing the expenditure on components. This is achieved by supplying the RF signal with a frequency-shift-keying between f0 and fu via an isolating amplifier (1) to two data channels, the first one of which successively contains a parallel or series resonant circuit (2) which passes the frequency f0, an amplifier (4), a rectifier (6), a Schmitt trigger (8), a pulse delay element (10) with a delay time of < one bit length and an AND gate (12), the Schmitt trigger output signal also being supplied directly to a second input of the AND gate (12), and the second one of which successively contains a parallel or series resonant circuit (3) which passes frequency fu, an amplifier (5), a rectifier (7), a Schmitt trigger (9), a pulse delay element (11) with a delay time of < one bit length and a first NAND gate (13), the Schmitt trigger output signal also being directly supplied to a second input of the first NOT AND gate (13), and by the outputs of the AND gate (12) and of the first NAND gate (13) being conducted to a second NAND gate (14). <IMAGE>

Patent DE-3810717-A1 (DE)
Inventor: BLOTENBERG WILFRIED DIPL ING
IPC: F04D27/02
Filed: 1988-03-30
Abstract: In the case of known control methods the intake volume flow to the compressor and the compressor final pressure measured after the compressor are included in the venting control. Disturbances in the through-flow which have their cause in a process downstream from the compressor are thereby only detected once they have spread through the compressor to the intake side. Under unfavourable conditions intervention by the venting control may therefore already be too late to prevent surging of the compressor. The new method is intended to rectify this drawback. 
<??>The new method proposes that in addition the delivery flow to the process downstream from the compressor be detected and taken account of in the venting control. This results in prompt reaction of the venting control to changes in the through-flow which are caused by the downstream process. 
<??>The new method is particularly suitable for the control of turbocompressors on which the downstream process is a possible cause of disturbances with changes in the through-flow.

Title: Fastening device
Inventor: TREFFER EDUARD
IPC: E05B1/00
Filed: 1988-07-04
Abstract: The fastening device is a variable handle for panel-like parts, for example furniture doors, in the case of which frustaconical spacer pieces serve as spacers between the panel, which is to be moved, and the actual bar-like handle, by means of which spacer pieces the distance between the handle and panel is varied by the selected diameter of the bores in the handle. A likewise frustaconical attachment part, in whose blind hole an internal thread is located, assumes the function of the nut. With the aid of the two frustaconical parts, very different handle shapes, handle colours and handle sizes can be achieved by using self-made handle strips, in the case of which dimensions and surface can be correspondingly freely selected.

Patent DE-3839131-A1 (DE)
Title: Air-conditioning system for vehicles
Inventor: FREITAG ELMAR DIPL ING
IPC: B60H1/00
Filed: 1988-11-19
Abstract: The invention relates to an air-conditioning system having two heat exchangers arranged in a housing for cooling and heating the air flow passing through them. An air-conditioning system of this type obtains a compact constructional form with an extremely low overall height by virtue of the fact that the two heat exchangers are arranged with approximately rectangular air-passage surfaces next to one another and crosswise to one another. An axial partition in the housing separates the air-passage surface of the heat exchanger for heating the air from the air-entrance opening of the housing and, as a result, the heat exchanger for heating the air only has air flowing through it which has left the heat exchanger for cooling the air.

Title: Measuring arrangement and method for measuring the solid mass flow of flowing gas-solid mixtures
Inventor: RICHTER SIEGFRIED DIPL ING
IPC: G01N27/22
Filed: 1989-03-25
Abstract: The invention relates to a measuring arrangement and a method for measuring the solid mass flow of gas-solid mixtures flowing in technological reaction spaces. It is the object of the invention that the mass flow be determined irrespective of the flow form of the gas-solid mixture, in order to ensure accurate control and reliable monitoring of the mass flow matched to the processing method. The object of the invention consists in eliminating the measuring problems resulting from the separation (segregation) processes in the mass flow measurement of the solid phase of gas-solid flows. According to the invention, the object is achieved in that the sensors and detectors are arranged on the delivery pipe, using the results of separation experiments, in such a way as is necessary on the basis of the separation and that significant density measured values, velocity measured values and flow cross-sections are obtained for calculating the mass flow. According to the invention, the density and concentration measured values are determined at time intervals which are significantly smaller than the propagation time of a closed plug of solid of a plug flow past a sensor. <IMAGE>
