Patent DE-3411316-A1 (DE)
Title: Device for connecting a pipe to a cylindrical housing
Inventor: DEUTZMANN THEODOR
IPC: F16L55/115
Filed: 1984-03-22
Abstract: A pipe piece is pushed into the cylindrical housing, into which pipe piece a circumferential groove is turned, towards the end, a circlip ring being fitted into said circumferential groove. A recess for holding the circlip ring is provided in a cover which fits onto the housing. The cover is screwed onto the housing by means of screws, and the pipe is at the same time firmly connected to the housing. In this way, it is possible to produce a simple and very firm connection of a pipe piece to a cylindrical housing, which connection can be released quickly and can be used advantageously wherever the rotating machine part which is to be driven cannot or must not be connected directly to the drive (for example the motor). <IMAGE>

Title: Device for connecting brake apparatuses of vacuum rail vehicle brakes
Inventor: PROKOP KARL
IPC: F16L23/04
Filed: 1984-04-09
Abstract: The brake apparatus has, for connection to a vacuum central control, a pipe connecting piece (7) which is provided at its free end with a thread (8) for screwing into a connecting piece (2) of a T-element or syphon element (1) of the vacuum central control. Adjacent to the rear end of the thread (8), the pipe connecting piece (7) has an annular flange-like holding section (10) which bears a radial face (11) at the front side and a conical face (12) at the rear side. In a second embodiment, the connecting piece (2) can have, instead of its thread, a cylindrical face (13) which, in the mounted state, is located opposite the thread (8) of the pipe connecting piece (7) with spacing for play. In this embodiment, the connecting piece (2) bears at its end a counter holding section (14) also with a front side constructed as a radial face (15) and a rear side constructed as a conical face (16). A clamping belt (18) engages around the holding section (10) and the counter holding section (14) and clamps them tightly and securely to one another by means of lateral conical sections (19). It is thus possible to bolt the brake apparatus (6) to connecting piece (2) of the previously customary design and, in a manner which saves fitting space, to insert it axially into the connecting piece (2) of a second embodiment with its pipe connecting piece (7) and to hold it by means of a flange-like connection. <IMAGE>

Title: Process for the production of lithographic printing plates
Inventor: KANADA EIJI
IPC: G03F7/07
Filed: 1984-09-28
Abstract: The invention relates to a process for the production of lithographic printing plates with a long printing life and resistance to scumming and abrasion of the silver image. In this process, a photographic element is subjected to brief high-intensity scanning exposure. The element is constructed from a support to which at least one base coating, a silver halide emulsion layer and a physical developing core layer are subsequently applied, the base coating containing about 80 % by weight or more of the total amount of finely divided powder contained in all the layers, and the powder having a mean particle size which is approximately equal to or greater than the thickness of the base coating. The silver halide in the emulsion layer contains at least 80 mol% of silver chloride and may contain up to 2 mol% of silver iodide. An antihalation device is provided on the underside of the emulsion layer, which reduces the reflection of the exposure light used to 10 % or less, and the exposed photographic element is then developed by a silver complex diffusion transfer process.

Title: Control circuit for a magnetic levitation vehicle
Inventor: BOHN GERHARD DR
IPC: B60L13/06
Filed: 1985-04-17
Abstract: The invention relates to a control circuit for a magnetic levitation vehicle which is guided controlled with the aid of supporting and guiding magnets along a travel path. The control circuit has a support circuit (2) for deriving the pick-up variables and an adaptive rail observer (20) for each supporting magnet, with which observer (20) a stable levitation is achieved in the base of the magnetic levitation vehicle. In order to ensure stable levitation of the magnetic levitation vehicle even in the case of multiple excitation oscillations of the travel path, the rail observer (20) is composed of a plurality of adaptive sub-observers (20-1 to 20-n) which can be each tuned to respective different resonance frequencies (F1 to Fn) of the travel path. <IMAGE>

Title: Noise- and impact-damped drive wheel, in particular for tracklaying vehicles
Inventor: MENKHOFF KARLHEINZ
IPC: B62D55/096
Filed: 1985-04-19
Abstract: The previous drive wheels for track drives and tracklaying vehicles are bolted by bolt connections to the axles or transmissions and thus securely connected by metallic means. By means of this connection, any impact which is produced as the chain runs into the wheel is transmitted to the axle or the transmission and, depending on the form and design, is passed on in amplified form. This noise- and impact-damped drive wheel in the patent application prevents the transmission of the noises and impacts because the force transmission between the drive wheel and the axle or the transmission takes place via damping bodies.
Patent DE-3517539-A1 (DE)
Title: Mounting for exchangeable scratchers
Inventor: PALLMANN WILHELM
IPC: B27L11/00
Filed: 1985-05-15
Abstract: The invention relates to the design and arrangement of scratchers for cutter rotors of chip-removal machines for wood. In this case, the mounting, proposed according to the invention, of the rectangular scratcher plates provided in each case with two parallel scratching blades in the cutter rotor takes place by direct non-positive contact of their scratching blade-free edges with the cutter or cutter set acted upon by the clamping force on the one hand and the rotor body on the other hand. This non-positive contact is brought about according to the invention by the scratcher plates being slightly wider than their receiving strip is thick, an excess of 0.2 mm having proved itself in practice.
Patent DE-3518562-A1 (DE)
Title: Air filter for living rooms
Inventor: HOELTER HEINZ DIPL ING
IPC: F24F3/12
Filed: 1985-05-23
Abstract: Main Application P 3517923.6 relates to a filter in which the air to be cleaned or already cleaned air is blown through wood packings, it being possible to provide the wood packings with humidifiers for intensifying the natural wood odour. In order to make the production of the air filter less expensive it is proposed, according to the invention, that the wooden filter be made of bark and/or bark chip meal or bark wool. Bark is a waste product and thus very cheap. In addition, bark contains the highest amount of tree resin which absorbs gaseous harmful substances and odoriferous substances and, moreover, retains very fine dusts from the air stream by its adhesive power.

Title: Use of coal mill waste air as secondary air in clinker firing
Inventor: ABELITIS ANDRIS
IPC: C04B7/47
Filed: 1985-06-07
Abstract: The coal mill waste air arising at various rates in pulverized coal-fired rotary kilns can replace a part of the secondary air in the clinker-firing process in a rotary kiln without a hazard if it is injected via its own pipe system (2, 2', 3) directly into the hot clinker on the grates (8) of the clinker cooler. The secondary air flowing in from chambers (9) underneath the grate can be reduced correspondingly. The number of passage orifices (7) through the grate should be reduced where coal mill waste air is blown in; there is no interference with the fluidization of the clinker if the coal mill waste air is introduced in such a way that a fluid bed around the tubes (2) is formed. <IMAGE>

Patent DE-3601540-A1 (DE)
Title: Heating coil having a cleaning valve
Inventor: LUBS WOLFGANG
IPC: F28G9/00
Filed: 1986-01-20
Abstract: Given the ever-recurring necessity for internal cleaning of heating boilers or other serpentine coils in which a medium is located, it has so far been necessary to produce a special cleaning circuit with a pump. In a heating coil having a cleaning valve, for example, this process is superfluous since the cleaning valve is easy to access from outside, with the result that it is easy for a dosed cleaning agent to be introduced into the interior of the serpentine coil. Of course, this eliminates the need to expose the inlet and outlet of the coil or to handle chemicals openly, and is thus less dangerous and also capable of being carried out more quickly by non-specialists. The treatment of the entire unit, which is necessarily kinder, thus also lends it a longer service life. Since the cleaning valve does not open until the container with the cleaning agent has been mounted, and immediately recloses after it has been removed, pollution is excluded. It is now possible to carry out cleaning without any assembly processes.
