Abstract: The compressor has paired bores (13A,14A) in cylinder blocks (1,2), with a swashplate (1) mounted on a rotary shaft (7) and accommodated in a crankcase (11). Double headed pistons (15A) are coupled functionally with the swashplate and of which each has a pair of piston heads for compression of cooling gas by a forward and backward movement in the bores coinciding with the rotation of the swashplate. Bearing components (8,9) are provided in each cylinder block (1,2), each of which comprises a cone roller bearing which takes up the radial and thrust load exerted on the rotary shaft (7). Each roller bearing is supported on an outer face-side end of the cylinder blocks (1,2), by a bearer component (3a,4a), and a spring (20) exerts a tension via the bearing on the rotary shaft (7). USE/ADVANTAGE - To improve the bearing mechanism of the rotary shaft of a compressor used in a road vehicle air conditioning plant.

Title: Heat-pumping solar collector
IPC: F24S10/80
Filed: 1993-08-11
Abstract: The invention relates to a heat-pumping solar collector with automatic circulation of the heat transfer fluid. The heat transfer fluid consists of at least two components, at least one of which is evaporable at operating temperature. The heat transfer fluid flows in a thin layer over heat-insulating elements and through evaporation absorbs the heat spreading to the covering panel. Through heat emission at an average temperature level and evaporation of components of the heat transfer fluid in an auxiliary gas, the collector is able to absorb heat and specifically the heat spreading to the covering panel, as well as that from the environment.

Title: Process and apparatus for the production of a twine
Inventor: LOSSA ULRICH
IPC: D02G3/22
Filed: 1993-09-18
Abstract: A process and an apparatus for the production of a twine. The apparatus possesses a spindle rotor (1) with a radially outward-guided thread-guide channel (1.4) following the spindle hollow shaft (1.2). The spindle rotor (1) forms the bottom of a pot. The outlet orifice (1.5) of the thread-guide channel (1.4) is located directly in front of the inner face of the pot (2). Two rotor spinning apparatuses (7-8; 10-11) are arranged one above the other in the pot. Guided into the spindle rotor is a feed conduit (6) for fibre material, which is divided into two branch conduits (6.1-6.2, 6.4) which are guided radially outwards and then upwards parallel to the spindle shaft within the wall (2). Each branch conduit is followed inwards by a supply pipe (6.3, 6.5) which opens into the rotor (8, 11) of one of the rotor spinning apparatuses. The thread-discharge pipes (7.1; 10.1) of the rotor spinning apparatuses extend coaxially relative to the spindle hollow shaft (1.2). The fibre material is spun in the rotor spinning apparatuses, in each case to form a thread which is discharged through the thread-guide channel (1.4) and the thread balloon adjacent to the inside (2) of the pot. The finished twine is discharged through the thread draw-off eye (3.1). <IMAGE>

Title: Automatic generation of a periodic pattern without the production of Moiré
Inventor: SATOH YOUICHI
IPC: H04N1/405
Filed: 1994-07-07
Abstract: In a device for generating a digital grey scale raster which comprises a multiplicity of periodic patterns, a configuration determining unit (53), using period constants (51), determines a grid (27) which displays the configuration of one of the periodic patterns in the digital grey scale raster. The period constants (51) and a function (50) which specifies a procedure for obtaining threshold values in a square area are supplied to a threshold value distribution unit (54) which rotates the threshold values formed by means of the function (50) by a raster angle. On the grid (27), the threshold distribution unit (54) expands threshold values which are magnified at a magnification ratio. When the threshold values on the grid (27) exhibit incoherent numbers, the threshold value distribution unit (54) rearranges the threshold values so that they exhibit coherent numbers. The threshold value distribution unit generates a period pattern signal (52) which indicates the threshold values with the coherent numbers. <IMAGE>
