Title: Fastening a race on the curved surface of a rotary tube
Inventor: FILGES RALF DIPL ING
IPC: F27B7/22
Filed: 1993-04-16
Abstract: When an internally toothed race is fastened on the curved surface of a rotary tube by being keyed to supporting plates lying on the curved surface of the rotary tube, relative displacements due to differing thermal expansion leads to loosening and wear of the tooth flanks of the keyed joint, with the result that the latter have to be tightened continuously and wearing parts have to be replaced. According to the invention, the proposal is to fasten the race (10) provided with teeth (14) by installation of the fastening elements (12, 17) and the supporting plates (13) in such a way that the said race is immobilised only in the axial direction and can move freely in the circumferential direction relative to the rotary tube (9). <IMAGE>
Patent DE-4316235-A1 (DE)
Inventor: DUVE MANFRED
IPC: A23L13/60
Filed: 1993-05-14
Abstract: The present invention relates to a process for producing a meat-based food product, in which lean beef and/or pork, in a first step, is preminced in a mincer and is then finely chopped in a cutter and the protein broken down, with cooling by addition of chopped ice or snow and in which, moreover, fatty pork is added to produce a fine meat emulsion. By the process according to the invention, the fine meat emulsion thus produced is charged into moulds, then scalded with steam in the cooking cabinet at approximately 70@ to 75@C and the mass obtained is then cut into small pieces after cooling, preferably into rod-like strips. These rod-like strips, in a following step, are deep-fried in boiling fat for a relatively short period. A meat-based food product is thus obtained which is dimensionally stable without use of a casing and at the same time can be kept for a relatively long period, this food product being produced without the use of preservatives and protein substitutes.

Title: Exhaust tail pipe for an aspirated exhaust engine
Inventor: LIN SHIN-SENG
IPC: F01N1/12
Filed: 1993-07-06
Abstract: The object of the present invention is to provide an exhaust tail pipe including a front perforated pipe with an exhaust silencer engine or exhaust muffler. The front pipe, which introduces outside air, was enclosed by an outer pipe on the outside. A central pipe was connected to a rear part of the front pipe and the inside of the outer pipe arranged and each perforated helical plate forming the multiple vortex was fixed between the central pipe and the outer pipe. And each vortical plate fixes the rear part of the front pipe between the outer pipe and the central pipe and was thereby relieved by the exhaust engine. The pressure of a partial exhaust gas flow is reduced by ducting outside cooling air and the pressure of residual gas flow further reduced, and since the gas flow had performed a vortex flow due to the vortical perforated plates, draws the exhaust gases in the pipe outlet strongly outwards.

Title: Process and extinguishing system for extinguishing a fire
Inventor: BUERGEL HANS-GERHARD DIPL ING
IPC: A62C35/58
Filed: 1993-10-20
Abstract: In many cases, the damage resulting, after a fire, due to the action of liquid extinguishing agent is greater than the actual fire damage. This also applies if the extinguishing agent is sprayed by means of a nozzle, as is used in the case of known extinguishing systems. The novel process is intended to manage with as little extinguishing liquid as possible when extinguishing a fire. Since the nozzle used is a two-component nozzle (1) in the case of which a gas - advantageously an inert gas - which is fed to the nozzle (1) and flows out at a high speed atomises the extinguishing liquid, this achieves a considerable increase in surface area with a high proportion in terms of the smallest droplets, with the result that the extinguishing agent can absorb a relatively large quantity of heat in a relatively short period of time. This increase in the extinguishing action in the novel process reduces the requirement for liquid extinguishing agent to a considerable extent with respect to the requirement in the case of known processes. <IMAGE>

Patent DE-4411813-A1 (DE)
Inventor: PANKNIN RALF
IPC: F24F11/02
Filed: 1994-04-07
Abstract: In order to condition continuously and reliably the air in containers in which heat is liberated, the invention proposes a method using at least two independent air-conditioning units connected to each other by a data line with a control system. The method is characterized in that, at any given time, at least one unit is not in operation and the total rating of the maximum number of units in operation is sufficient to condition the air in the space under any conditions. At periodic intervals, the units not in operation are started up and the same number of operating units shut down. Maintenance work can therefore be carried out on the units not in operation, without interrupting the continuous conditioning of the air in the container. The invention also proposes an air-conditioning unit for carrying out the method. The unit has all its components located in a single housing (1) and is characterized in that the condenser (2) is located on the aspiration side of at least two open-running radial-flow fans (3, 4) fitted in the housing (1), as well as in that the whole of the housing interior on the delivery side of the fans (3, 4) can be placed under pressure by the fans and the air which has passed through the condenser (2) is blown out of the housing (1) through holes (7) located at any point in the housing wall enclosing the space (6) placed under pressure. This design enables particularly compact and powerful units to be built which take up little space in the container, can be fitted anywhere and are easy to install and replace. In a preferred embodiment, the air-conditioning unit also has an electric heater with which the container can be heated after being installed at low temperatures at which the equipment causing heat to be liberated cannot yet be operated.
