Filed: 1991-01-17
Abstract: In its rear area, the trolley frame has two forwardly inclined, and upwardly directed bearers which are double-armed, and support the basket.  The bearers incorporate support and stop means which are so arranged that a downwardly inclined component in the push direction of the trolley is formed to accommodate objects which are pref. cubic in shape. Above this forwardly and downwardly inclined compartment (16), the bearers (6) have further support and stop members (14,15) to form at least one further downwardly inclined compartment (16).  The angle of inclination of the compartments is at least 9 deg.  The support members are formed by flat wire netting (17) or similar, or by cross bars, and the stop members (15) are formed by angled sections on the wire netting or cross bars.

Title: Quality controlling spot welds
Inventor: FORTMANN MANFRED DIPL ING
IPC: B23K11/25
Filed: 1991-04-18

Inventor: PREISLER EBERHARD
IPC: H01L39/16
Filed: 1991-06-18
Abstract: A resistive current limiter takes the form of a hollow cylinder and is composed of high-temperature superconducting material. In this connection, the high-temperature superconducting material may be a polynary oxide. To produce said resistive current limiter, a homogeneous melt is prepared from an oxide mixture, suitable for forming high-temperature superconductors, in a specified stoichiometry and said melt is allowed to run, at temperatures above 900 DEG  C., into a casting zone which rotates about its horizontal axis. The molding, solidified as a cylinder, is removed from the casting zone. The cylinder is sawn so as to produce a gap extending parallel to its axis. Furthermore, a multiplicity of slits are sawn into the cylinder parallel to the gap. Finally, the cylinder is heat-treated for up to 150 hours at 700 DEG  to 900 DEG  C. in an oxygen-containing atmosphere.

Title: Refrigeration with air as refrigeration medium and cooling agent - having mostly isothermic compression and adiabatic approximately isentropic expansion using screw compressor for compression with water injection
Inventor: FOERSTER HANS DR
IPC: F25B9/00
Filed: 1991-08-16
Abstract: The compression takes place in one stage in the screw compressor (6), and the compressed air is then diretly cooled in a scrubber (10), with a counter flow of the cold or cooling water. Following the re-cooling the dripping water is separated from the air in a fine drop separator, and is adiabatically expanded across a fast running turbine (8), which is coupled with the screw compressor (6). The snow resulting with the expansion of the undried air is separated by the snow separator (12), and this dried air is led to the cold room (11) and is sucked from the screw compressor across the air filter (14). The process with indirect heat exchange is realised with the help of changeover recuperators, for low temp. applications, with the freezing out of dampness in alternation with the oeprating regime. USE/ADVANTAGE - Cold stores, meat packing plants, fish processing plants also further industrial application. Competes with cold vapour processes in tyupical applications, but offers environmental advantages and as open process ensures a completely air supply free of air.

Title: Measuring thickness of surface layers in nanometre region - using interaction vol. produced by primary electron beam in raster electron microscope and energy-dispersive X=ray spectroscopy.
Inventor: HOFMANN ANNEGRET DIPL PHYS
IPC: G01B15/02
Filed: 1992-04-04
Abstract: The method involves using an interaction vol. produced by a primary electron beam in a raster electron microscope and an x-ray spectrum acquired by energy dispersive x-ray spectroscopy.  The vol. corresponds to a hemisphere of radius equal to the primary beam penetration depth irrespective of the order of the solid body. The vol. of the layer inside the interaction vol. is set equal to the vol. of a spherical section with the thickness of the layer, whereby the section vol. is small compared to the hemisphere vol.  The vol. of the hemisphere and section are proportional to the intensities of the x-ray spectra produced in the whole interaction vol. and surface layer.  The thickness is derived from the ratio of the hemisphere and section vol.

Title: Injection moulding of thermoplastic components - has 1 and 2 polymer storage chambers, with vol. of the 2nd chamber being variable to control flow out of 1st chamber to cavity
Inventor: SCHRAMM KLAUS PROF DR ING
IPC: B29C45/32
Filed: 1992-06-30
Abstract: Process uses a screw injection machine which forces polymer from a 1st storage chamber into a tool cavity. Shrinkage in the cooling moulding is compensated by back pressure provided by a 2nd storage chamber with a piston which forces polymer into the cavity. The vol. of the 2nd chamber can be varied during emptying of the 1st chamber by piston movement. Tool filling rate is independent of the emptying rate of the 1st storage chamber. The vol. of the 2nd storage chamber is pref. increased during the 1st phase of the injection cycle and is controlled by computer programme. Vol. changes pref. depend on the position of the screw and cavity pressure during emptying of the 1st chamber. Vol. changes can also be made during the follow-up pressure phase according to a given programme. When the follow-up pressure phase is completed the 1st and 2nd storage chambers are connected and remaining polymer is forced back into the 1st chamber. USE/ADVANTAGE - The process and appts. are used to mfr. injection moulded components. Allows the shortest emptying time for the first chamber while controlling pressure and cavity filling rate to give the optimum product.

Title: Rotary potentiometer resistance path equaliser - uses laser beam to cut resistance groove in path in response to differences between optimal and nominal resistance values fed into differential amplifier
Inventor: HATSCHER WERNER
IPC: H01C17/242
Filed: 1992-07-15
Abstract: The appts. for equalising a resistance path (6) of a rotation potentiometer consists of a rotation arm (2) having a perpendicular rotation axis (1) with a slide contact (5) fitted below it and rotatable also about the axis. At the end of the arm a mirror galvanometer (7) has a rotation mirror (10) which receives a laser beam (9) and deflects it downwards onto an edge of the resistance path to produce a groove (S). Both the slide contact and the laser beam are rotated simultaneously around a section of a circle whose centre coincides with the axis. At certain angular positions around this section, the optimal resistance value is compared with the nominal value and any differences are used by a differential amplifier (15) to feed a control signal to the mirror galvanometer which causes the laser beam to deflect within a certain range (19) and thereby adjust the cut path so that it returns to a set curve path. ADVANTAGE - By using deflector mirror for controlling beam deflection, process is economic to use.
