Title: Grinding machine
Inventor: DUFOUR PAOLO
IPC: B24B5/16
Filed: 1984-02-16
Abstract: Grinding machine for profile grinding, comprising a tool carriage (10) which is displaceable within a plane defined as the primary or main axis (Z), which tool carriage is fitted with a grinding wheel (12) which can be adjusted in a plane located at right angles to the Z-axis and defined as the secondary or regulatory axis (X). A monitoring and control system (20-47) provides the tool carriage (10) and the grinding wheel (12), by way of the drive motors (11, 13), with the required feed movement within the movement planes defined by the abovementioned axes. The monitoring and control system (20-47) comprises a memory unit (43) in which the nominal values of ordinates or ordinate increments of a curve (DE) are stored. This curve (DE) corresponds, without taking standardising factors into consideration, to the profile which is to be given to the workpiece. These values are taken from the memory unit (43), in each case according to the position of the tool carriage (10) and thus of the grinding wheel (12) with respect to the main axis, and are converted into a control signal for the feed of the grinding wheel (12) along the regulatory axis. <IMAGE>

Title: Refrigerator or freezer cabinet with dry air preparation
Inventor: MANDL PETER DIPL ING
IPC: F24F3/14
Filed: 1984-02-24
Abstract: The refrigerator or freezer cabinet according to the invention, which is based on the Carnot process, permits energy-saving utilisation of the existing refrigerator for simultaneous or alternative dry air preparation for different applications, such as e.g. the dehumidifying of laundry or laundry drying rooms and bathrooms. With the aid of a second evaporator which can be connected into the refrigerant circuit or of a special pipe evaporator as well as of a blast air circuit, which runs firstly via the additional evaporator and then via the condenser, the moist air extracted from the space to be dried is first cooled and dehumidified and then heated again. As dry warm air it passes again into the space equipped with moist articles. The switching in and output of the compressor for the refrigerator and of the motor for the air blower takes place by means of temperature or humidity regulators. These are controlled via suitable sensors which are situated in the refrigerating chamber or in the drying chamber. Operation can also take place by means of manual control. No additional heating energy is required for the dehumidifying process.

Title: Simultaneous SO2 and NOx separation preferably in fluidized-bed combustion plants
Inventor: HOELTER HEINZ DIPL ING
IPC: C10L9/10
Filed: 1985-08-24
Abstract: The invention relates to a process for the simultaneous SO2 and NOx separation from the flue gases of fossil-fuel fired combustion boilers, preferably fluidized-bed combustion plants. It has been found that, by the addition of lime and ammonia salt to the fuel mixture during combustion, SO2 is separated off via binding to lime and NOx is converted to elemental nitrogen as a result of reduction by ammonia. In order to prevent the lime being able to react with the ammonia salts (specifically in the case of wet coal) prior to use in a combustion chamber and NH3 being liberated, according to the invention, pitch, asphalt, slack waxes etc. are added to the fuel mixture and are pressed to form fuel pieces in the form of briquettes, egg coal etc., in order to insulate the added salts and enable them to react only in the combustion chamber.
