Patent DE-3504184-A1 (DE)
Title: Process for preparing polycrystalline silicon layers having smooth surfaces
Inventor: BERTAGNOLLI EMMERICH DR PHIL
IPC: H01L21/285
Filed: 1985-02-07
Abstract: The deposition is carried out in two stages with an interposed inert-gas flushing step, a first stage involving a deposition (3a), which is thinner compared with the second stage, of amorphous silicon, immediately followed by the second stage in which, in the same reactor but at elevated temperature, the deposition is terminated with a polysilicon layer (3b). The process avoids "hillocks" (4) in the polysilicon layer (3) deposited on single-crystal silicon (1) and is used in the fabrication of low-resistance base terminals in bipolar transistor circuits. <IMAGE>

Title: Guide for a sunshade installation
Inventor: CLAUSS MANFRED
IPC: E06B9/92
Filed: 1985-03-13
Abstract: A guide for a sunshade installation has a profiled guide tube for a running carriage which is guided in a guide duct of the guide tube by means of rollers. A lead-through slot, delimited by longitudinal webs running towards one another, opens into the guide duct. In the mounted position of the guide tube, the lead-through slot is located on its underside and forms, by means of its longitudinal webs, running surfaces for the rollers. The upper wall, opposite the lead-through slot, and the side walls of the guide tube are designed in a continuous manner. Through the downwardly open guide duct, dirt and dust can easily fall downwards out of the guide duct again and not become caked in there. As a result, it is ensured that the rollers can run in the guide duct with low friction and in a smooth and problem-free manner.

Title: Method and device for cleaning a receptacle filling machine, especially a vacuum filling machine
Inventor: WEISS WILHELM
IPC: B67C3/26
Filed: 1985-03-27
Abstract: In a method for cleaning a receptacle filling machine having a boiler for the filling liquid, on which a plurality of downwardly projecting filling elements are arranged, once the cleaning liquid has emerged from the filling nozzle and the return air pipe, it is deflected upwards, is moved further upwards, divided into two partial streams, through the bore of the centring bell and along the outside casing of the centring bell, is then guided further upwards on the outside surface of the filling element and is finally collected. In this manner, all the important inside and outside regions of the filling element are forcibly permeated by large quantities of liquid and are therefore intensively cleaned, it being possible to maintain a closed liquid circuit at all times. <IMAGE>

Title: Circuit arrangement for A/D conversion with filters for band limiting
Inventor: ALI AMAR DR
IPC: H03M1/00
Filed: 1986-02-25
Abstract: The invention relates to a circuit arrangement for A/D conversion in which the useful signal is to be limited to the bandwidth B. For this purpose, the signal is first supplied to a simple low-pass filter (1) having little edge slope at the cut-off frequency n.B. The sampling and A/D conversion of the filtered signal is effected at the sampling rate 2n.B in the sampling circuit (2) and A/D converter (3). The signal passes through an ideal digital low-pass filter arrangement with linear phase characteristic (4) at the same sampling rate 2n.B. At the output (A) of the filter arrangement (4) the useful signal has the bandwidth B at a sampling rate of 2n.B of the digital values. This sampling rate can then be reduced by the factor k to a minimum value of 2.B in a second sampling circuit (5). <IMAGE>

Filed: 1986-11-27
Abstract: Bulk material containing vaporizable ingredients, such as lignite, hard coal, peat, waste wood, clarifier sludge, waste sludge, contaminated earth, catalysts, zeolites and filter cake, is conditioned by means of a vibrating plate conveyor divided into a heating section and a drying section, using an indirect heat exchange method. The bulk material is heated in an enclosed heating section while withdrawing the vapor from this section. In the downstream enclosed drying section, the vaporizable fractions contained in the bulk material are further reduced with the aid of heat supplied indirectly, the vapor being withdrawn. The bulk material is separated several times into coarse and fine fractions utilizing at least one slotted grid, the fines being immediately recycled and remixed with the coarse fractions which have a higher water content. The bulk material is mixed several times while being heated in the drying section before discharge.

Title: Method and device for operating an absorption heat pump
Inventor: MALL KLAUS
IPC: F25B15/04
Filed: 1987-02-19
Abstract: The invention concerns a method and a device for operating an absorption heat pump. If a conventional absorption heat pump is operated for a long time, considerable quantities of inert gas collect in the absorption heat pump, hindering proper operation. According to the invention it is proposed that a corrosion inhibitor be added to the absorption solution, and a cold, coolant-rich absorption solution be sprayed in the upper part of the rectifier. In this way, the formation of inert gas can be drastically reduced.
