Patent DE-2751148-A1 (DE)
Inventor: WOLTER HEINZ
IPC: E05C9/08
Filed: 1977-11-16
Abstract: The lock (2) has a bowl-shaped disc (24) which is mounted rotatably in the lock cover (23). It has two stop faces (25, 26) for the locking bit of a rotary cylinder, which engages into the bowl-shaped disc, and a driving disc which is mounted eccentrically relative to the latter and which actuates the lock bolt. The bowl-shaped disc has two markings (R, L) for right-fastening and left-fastening, each of which can be set to a fixed mark (30) of a collar of the lock cover. To convert from right-fastening to left-fastening, the lock is fitted rotated through 180 DEG  and the corresponding marking (L) of the bowl-shaped disc is set at the fixed mark (30). Because the bowl-shaped disc (24) serves as an intermediate member between the bolt and the espagnolettes, on the one hand, and the rotary cylinder actuating the lock, on the other hand, the lock can be used selectively for right-fastening or left-fastening without any constructional change. <IMAGE>

Title: Chemical purificn. of effluents by metering representative samples - branched from flow circulated continuously by pump ensuring homogeneity
Inventor: FIORATTI ELISEO DR
IPC: C02F1/52
Filed: 1978-07-25
Abstract: The inlet of a fluid transporting arrangement for continuously taking samples of effluent from a tank and transmitting them to a measuring container in which there is a sonde for determining the degree of impurity, is connected to suction inlets spaced out from each other, in the purifying tank for the effluent. A suction pipe with openings in the effluent tank is connected to a circulating pump. Even in tanks where the degree of mixing is very poor, the transmitted sample is fully representative of the condition of the tank when the sample is taken. The pipes with suction openings take up very little space, so that even in cramped conditions there is no interference with other details installed in the tank.

Title: Drying equipment for continuous pile fabrics - with raising roller and after-cooling arrangement to fix pile erect
IPC: D06C7/00
Filed: 1979-05-23
Abstract: Equipment for the heat-treatment of pile fabrics in continuous length, partic. for drying carpet material with a voluminous pile, in which temps. of >=100 degrees C are utilised has a pile-raising device which mechanically beats and opens the pile whilst the material is still hot.

Title: Circuit for connecting data display to telephone line - giving initial low impedance termination of incoming line to operate exchange equipment for connecting call
Inventor: KIESER HANS JOACHIM DIPL ING
IPC: H04M11/08
Filed: 1979-08-03
Abstract: The data display system, typically a television receiver, is connected to the telephone subscriber line (a,b) through a data modem (M). Transition from normal telephone connection to data transmission is achieved by change over contacts (k1,k2). In order that, on selection of data display, the telephone subscriber line is recognised at the exchange as calling, a low impedance (RU) is connected in parallel with the modem (M). With the impedance sufficient current flows at the initial reduced line voltage to operate the circuits at the exchange. When the exchange connects the full voltage to enable dialling the parallel impedance take on a high value automatically, and the modem becomes operational. The impedance is typically a voltage sensitive resistor or a semiconductor circuit with FETS controlling the resistance.

Title: Recycle of carbon di:oxide to air and steam coal gasifier - driving gas turbine, increases overall process energy
Inventor: ZIMMERMANN FRITZ ING GRAD
IPC: C10J3/78
Filed: 1979-12-01
Abstract: A gas turbine is driven by the prods. of combustion of lean gas from the pressure gasification of coal with steam and air. The novelty is in the arrangements for recycling the CO2 produced in this gasification to the gasifier. The gasifier effluent passes to a waste heat boiler and thence to a H2S- and CO2- removal washer, run at approx. the dew point of the raw gas and at gasifier pressure. The CO2 regenerated from the wash liquid is mixed with a side stream of air from the gas turbine compressor, and the mixt. further compressed and returned to the gasifier. The arrangement displaces gasification steam, thereby reducing the amt. of latent heat in the stack gas and increasing the energy of the integrated process. Further, the steam displaced from the pressure gasifier can be used to generate power in a steam turbine.
