The invention relates to a process of heat transformation to convert the low-temperature waste heat from cooling circuits of block-type thermal power station (BTPS) reciprocating-piston combustion engines into steam or other heating media of a temperature required for operation by adopting the principle of the high-temperature heat pump according to which the low-temperature heat produced by recooling the engine cooling circuits to their required inflow temperature required by construction is transferred to a liquid working medium, is absorbed by the working media vapors by partial evaporation, and is brought, by compressing and condensing the working medium vapors, to the temperature of the in-plant heating media and is transferred to them. It is an object of the invention to provide a heat transformation process and devices for realizing the process according to the principle of the high-temperature heat pump using mechanical vapor compression by means of which the waste heat not only of the hot exhaust gas, but also the one of a proproportion as large as possible of the low-temperature waste heat from the cooling circuits for the cylinders, the lubricating oil, and the charging air/fuel mix may be used up to a lower temperature limit to be fixed for each project by conversion into the in-plant common heating medium in a technically reliable manner and at an economical relationship between the investment and operating expenditures to the output from the recuperated energy in reciprocating-piston engine BTPS for the heat supply to commercial and industrial enterprises. This is attained by the fact that inventive connections and devices prevent a drop below the ambient pressure in the critical low-temperature range and in all of the operating conditions of the heat transformer and the energy required for vapour compression is reduced to a minimum and, using steam expansion or hot-air prime movers, is gained completely or in part from the exhaust gas content of the BTPS engine (FIG. ).

A process for documenting the position of a dental casting model relative to the mold surface is distinguished by the fact that the position of the model on the gate molder is pictorially recorded prior to it being embedded. This is expediently done simultaneously to the pictorial fixing of a marking which reproduces the position of the surface of an assigned mold in relation to the cast object or to the gate molder. This can be a marking which is physically connected to the gate molder. However, it can also be contained in the recording instrument or stored in the analyzing unit of the recording instrument. Where different sizes are used, the assignment of the respectively pertinent marking to the gate molder of predetermined size can be realized automatically. Instead of the use of such a marking, it is also possible additionally to take a pictorial record of the mold following the embedding, in order to be able to interrelate the position of the object and the position of the mold surfaces by comparing the records prior to and following the embedding. Instead of this, it is also possible to document the model in the actually used muffle mold shell or to document the model or the mold cavity of the finished muffle.

A braking device for braking the saw chain of a portable motor-driven chain saw having a safety device which has a mass member, a locking lever being provided which is pivotably mounted on the hand guard lever and bears the mass member at its free, sprung end, co-operating by its other end with a control cam which bears against the brake lever and via which the braking operation of the rotating saw chain is controlled, in such a way that the braking operation of the rotating saw chain is automatically initiated, if an uncontrolled acceleration takes place, by the saw rolling down the timber trunk to be sawn at the moment when the saw becomes jammed, with the consequence that the resulting braking force counteracts the accelerating force, so that the recoil angle of the saw is reduced.

The invention relates to an oil pump for hand rail chain saw machines in which a pump plunger has an annular groove at its end remote from the drive and which is connected via a duct to the pump oil pressure channel, so that the sucking in of secondary air, high wear and an undefined lubrication are avoided.

The invention relates to a braking mechanism for braking the chain of a portable power chain saw when a hazardous state occurs. The operating lever rotatably mounted on the chain saw casing is in operative connection with a control lever acting on a brake band by means of a lever-like device. Thus, in the braking position the control lever is transferred into an angular position with a simultaneous position change of the two brake band articulation points. As a result, the brake band is applied to the brake drum, which ensures that the braking mechanisms act without any delay.

The invention relates to an exhaust silencer for internal combustion engines, particularly for manually operated appliances, in which a reduction of the contact and exhaust gas temperatures in order to prevent fire risks on contact with easily flammable objects, particularly forest fires, during the putting into operation of the manually operated appliance and with the supply of a large quantity of fresh air compared with the quantity of exhaust gas in order to bring about a maximum cooling of the hottest gases and/or the outer walls, is achieved in that the wall of the exhaust silencer shell portion which bounds the cooling pipe on one side, following the final outlet hood facing the pipe output port for deflecting the exhaust gas has a negative angular variation with an angle of approximately 2.degree. to 8.degree. for forming a pure or fluidic logic element.
