Patent DE-3127428-A1 (DE)
Title: Cigarette pipe with water filter
Inventor: ZAJONZ ARNOLD
IPC: A24F13/06
Filed: 1981-07-11
Abstract: The function of the cigarette pipe with water filter is that the cigarette smoke generated during smoking is filtered through water, the harmful constituents being precipitated. An illustration of the principle of the cigarette pipe with water filter is shown in the attached drawing. According to the drawing, the cigarette is inserted vertically into the cigarette attachment (item 1) after the filter (item 2) has been filled with the necessary amount of filter water. Inside the body (item 3) is the inhalation tube (item 4) through which the smoke is sucked into the filter paper. The mouthpiece (item 5) leads into the upper part of the body. The filter water can be exchanged as desired by simple pouring-out and refilling. It must be stressed that no change in flavour during smoking occurs despite the filtration. Moreover, an additional optical and acoustic stimulus is produced when the cigarette smoke is drawn in, by the "bubbling" of the filter water which takes place at this time. The cigarette pipe with water filter can be produced in various shapes and sizes, and made from all suitable materials. <IMAGE>

Title: Device for fixing a pipeline
Inventor: KLEZATH HERMANN DIPL ING
IPC: F16L59/135
Filed: 1981-07-31
Abstract: In order to fix cold-insulated pipelines provided with a diffusion-inhibiting protective casing, use is made of bearing shells which consist of insulating material and enclose the pipeline at fixed points. They are fixed with pipe-securing means. Between bearing shell and pipe-securing means there is a gap into which a diffusion-inhibiting protective casing usually consisting of a metal sheet is subsequently introduced. This fairly stable fixing device has an exposed bearing shell. It is subjected, in an unprotected state, to exterior mechanical loadings. The diffusion-inhibiting protective casing is difficult to mount. The bearing shell can be pushed away from the desired position if the cord insulation between pipeline and diffusion-inhibiting protective casing is subsequently introduced. According to the invention, the diffusion-inhibiting protective casing (6) is fixed on the bearing shell (5), in particular, by adhesive bonding. The productive casing (6) has protrusions (11, 12). Outer protrusions (11) centre the pipe-securing means (7) and inner protrusions (12) centre the bearing shell (5). Connection stubs (13), of the protective casing (6), axially projecting beyond the protrusions (12), ensure satisfactory connection to the protective casing (3) and the cold insulation (2) of the pipeline (1). <IMAGE>

Title: Coffee-making machine with fully automatic descaling and water treatment devices operated electrically in a similar manner
Inventor: THUERER HARRI
IPC: A47J36/42
Filed: 1981-08-25
Abstract: The invention relates to a fully automatic continuous descaling of coffee-making machines. Previously, coffee-making machines were cleaned with chemical agents at intervals when they became scaled, which required considerable expenditure in money and time. Furthermore, a greatly scaled coffee-making machine requires considerably more energy, thus entailing higher costs. All these disadvantages were eliminated in that a plurality of balls of appropriate diameter are introduced into an electrically heated water heating chamber, which balls are kept in a permanently rolling movement on the surface of the water heating chamber due to the cold water flowing in at intervals and an occurring accumulation effect. Due to the rolling balls, relatively small particles of settled lime are continuously loosened and flushed via the rising pipe with the heated water into the coffee filter. Further details are illustrated in the drawing, Fig. I and Fig. II.

Outside the pressure control valve housing (2, 3) an element (20) working as a function of the temperature is arranged, on which a second permanent magnet (22) is arranged, which is aligned with the first permanent magnet and is axially magnetised so that a non-contacting repellent force effect is produced in relation to the first permanent magnet (15). In addition a magnet winding (29) can be arranged on the temperature-dependent element (20), which is excited as a function of operating variables of the internal combustion engine, for example during acceleration or at full load. <IMAGE>
Patent DE-3142390-A1 (DE)
Title: Pressure reservoir
Inventor: BRENZINGER KARK HEINZ
IPC: F15B1/14
Filed: 1981-10-26
Abstract: The invention is based on pressure reservoirs in which a diaphragm which divides the housing into two chambers of variable volume is clamped by a retaining device. In known reservoir designs, pressure differences, which support a loosening of the diaphragm from the retaining device, can occur at the clamped end of the diaphragm. In contrast, in accordance with Fig. 2, the invention proposes that, for secure mounting of the diaphragm, a connection be produced between the chamber (21) which is subject to oil pressure and the clamped end of the diaphragm (19) via pressure medium passages (14, 15, 26) in the retaining device (10). Pressure differences at the clamped end of the retaining device (10) are prevented from the start by such a design. <IMAGE>
