Patent DE-3127680-A1 (DE)
Title: Self-aerated extractor
Inventor: GAEBELEIN RAIMUND
IPC: B08B15/02
Filed: 1981-07-14
Abstract: The extractor for polluted air is provided with a pressure space (26) above the window (16), which pressure space is closed at the bottom by an air-permeable web (28) made of a narrow-mesh filter or cloth. Air passes from the pressure space (26) through the web (28) in a laminar flow. This air slowly descending in the manner of a block is sucked into the chamber (10) through the air throughway (17) at the bottom end of the window (16). The amount of air which enters from the pressure space (26) roughly corresponds to the amount of air which is conducted away through the extractor channel (18) so that the air equilibrium is not disturbed in the room in which the extractor is installed. <IMAGE>

Title: Process for the cylindrical grinding of workpieces
Inventor: MUELLER JOSEF ING GRAD
IPC: B24B5/01
Filed: 1981-09-14
Abstract: The process for the cylindrical grinding of workpieces is carried out by a grinding wheel, the outer grinding surface of which is bevelled over its greatest axial extent. The workpiece is fed, at a plunge-cut rate dependent on the volume of material removal, until the grinding-wheel end edge forming the end of the bevelled region makes contact with the workpiece surface, with the result that, by means of the cylindrical part of the grinding wheel, a material layer of defined thickness is removed by plunge cutting. The workpiece is then advanced in the direction of its longitudinal axis, the bevelled central surface of the grinding wheel removing material over its entire width and the workpiece surface, from which material has been removed, is finished by the cylindrical outer surface. This process can remove, in one stroke, a quantity of material which corresponds to the material feed or to a comparatively large fraction thereof. As a result, in contrast to the known longitudinal-grinding process which requires a large number of strokes to achieve the finished size, a considerable amount of time is saved.

Title: Process for the operation of an absorption heat pump and heat pump for the performance of the process
Inventor: NOAK ROLF DR ING DR
IPC: F25B30/04
Filed: 1982-01-09
Abstract: In a discontinuously operated absorption heat pump, unsaturated solvent flows in a first phase from a container (1) to a stripper (3), in which refrigerant is driven off and, after a separation in the container (1), is liquefied in a condenser (4). Heat is liberated here. During a second phase, the hot solvent flows from the container (1) through a heat exchanger (6), where heat is liberated, and back to the container (1). During a third phase, liquid refrigerant flows from the condenser (4) through an evaporator (5), where it takes up heat from the surroundings. The evaporated refrigerant then reaches the heat exchanger (6) and, in common with circulating solvent, the container (1). It is absorbed again by the solvent, heat being liberated in the heat exchanger (6). During the then succeeding fourth = first phase, a circulation from the container (1) via the heat exchanger (6) to the stripper (3) and back to the container is switched in when the solvent becomes weak in refrigerant. The heat supplied to the stripper (3) is liberated in the heat exchanger (6), i.e. a direct heating operation takes place. <IMAGE>

Title: Process for producing a sound-absorbing filling for a silencer as well as sound-absorbing filling produced by this process
Inventor: SEITZ WILFRIED
IPC: F01N13/18
Filed: 1982-02-13
Abstract: The invention relates to a process for producing a sound-absorbing filling for an internal-combustion engine silencer from mineral wool at least partially dimensionally stabilised by means of a synthetic resin binder. Until now, such fillings have generally been produced in the form of two main shells to be pushed into the silencer on both sides of the exhaust pipe, the use of which shells presented difficulties during fitting, in particular whenever a metal wool sock was also laid over the perforated exhaust pipe. According to the invention, the silencer filling is produced as a one-piece moulding together with the metal wool sock (3) arranged in it, by the metal wool sock (3) being drawn onto a core (7), corresponding to the exhaust pipe, the core (7) being wrapped in layers of nonwoven mineral-wool fabric (9), at least partially impregnated with a synthetic resin binder, the entire article surrounded by a circumferential mould (15) and thermally cured, and the finished moulding then demoulded. The silencer filling thus produced can be fitted without any problems by pushing into the silencer from the side. <IMAGE>

Title: Method for the assembly of a constant-velocity sliding joint of annular construction
Inventor: NAGEL HERBERT
IPC: F16D3/227
Filed: 1982-02-17
Abstract: The invention relates to a method for the assembly of a constant-velocity sliding joint of annular construction, the longitudinal grooves of which are set circumferentially against the axial direction and the outer ring of which is accessible axially from one side only. In order to make possible a hard press fit between the hub and the shaft, the invention proposes an assembly method in which, upon installation of the driving balls, the hub can already be arranged firmly on the shaft and in which only relatively small swivelling angles between the hub and the cage, on the one hand, and the outer ring, on the other hand, are required. Just two driving balls are installed, pairwise, and, for this purpose, a longitudinal groove pair which emerges from the outer ring on the outside of the angled constant-velocity sliding joint and converges towards the shaft is chosen. The angling and introduction of a pair of balls is repeated several times at different circumferential positions until all the driving balls have been installed.
Patent DE-3207890-A1 (DE)
Title: Charging plant
Inventor: CARTUS WERNER
IPC: F27D3/00
Filed: 1982-03-05
Abstract: A plant for charging firing kiln carriages with green ceramic bricks coming from a press is constructed such that in fully mechanised, automatic operation, green bricks of small format, e.g. of 75 mm edge length, if necessary stacked on top of one another in several layers, are filled into cassettes, and these cassettes are stacked and travel as a stack to firing kiln carriages and are set down on these. The same charging plant can be used for unloading the full or empty cassette stacks from the kiln carriage and for conducting the full cassette stacks for charging a removal belt with the green bricks, or for conducting the empty cassette stacks into the press region for filling with green bricks. This is achieved, as shown in Fig. 1, in that the green bricks (16) are first pushed together to form rectangular layers on a collecting conveyor belt (1), and are then transferred by a green brick transferrer (3), equipped with vacuum lifters, to cassettes (17) (fed continuously on a fine supply conveyor belt 7 from a parallel discharge conveyor belt 3 with a cassette transferrer 4). The cassettes are placed on top of one another to form stacks (19) and are then moved to the kiln carriage feeder (9) which transfers the stacks (19) onto the kiln carriage (21), or sets the stacks (19) down after firing onto the supply conveyor belt (7) for transport in the opposite direction to an unloading belt arranged at the position of the collecting conveyor belt (1), or in the case of empty stacks (19) sets them down on the discharge conveyor belt (8). <IMAGE>

Patent DE-3241965-A1 (DE)
Title: Baking oven
Inventor: GERL JOSEF
IPC: F24C15/00
Filed: 1982-11-12
Abstract: The baking oven has a cooling-air fan outside the cooking space as well as a vapour extractor which opens into the cooling-air flow channel and exerts a suction effect on the outlet flow. In order to obtain vapour extraction immediately on reaching the volatilisation temperature in the baking oven it is necessary to switch on the cooling-air fan even before cooling of the heat-sensitive components in the switch chamber is necessary. The consequence is increased power consumption and an unfavourable cold air flow outside the baking oven. These disadvantages are avoided according to the invention in that a thermostat which controls the cooling-air fan is provided which has directly allocated to it a dedicated heating resistor which is connected in the heating circuit of the baking oven heating element and which simulates an increased environmental temperature for the thermostat. <IMAGE>
Patent DE-3242946-A1 (DE)
Title: Universal-joint shaft of adjustable length
Inventor: KLISCHAT DITMAR
IPC: F16C3/03
Filed: 1982-11-20
Abstract: The object on which the invention is based is to provide a universal-joint shaft with which the torque is transmitted in the region of the spline end via driver pins and with which it is guaranteed that approximately the same loading (surface pressure) will occur on both shaft parts. This object is achieved according to the invention by virtue of the fact that the centre lines of the driver pins are arranged on a circle diameter which is smaller than the calculated diameter within the spline end. This ensures that there is a relatively large contact surface for the driver pins in the inner shaft part, in which the higher forces occur.
