Title: Apparatus for scribing characters, numbers or drawings
IPC: B27C5/10
Filed: 1993-07-15
Abstract: Apparatuses for scribing characters, numbers or drawings, having scribing tools (9) driven by an electric motor, require precise setting of the scribing depth. To this end, known apparatuses of this type have a spacer (11) which can be adjusted by means of a screw connection to the mounting (3) with the drive motor (4), the mounting (3) being provided with an outer thread (15) and the spacer (11) with an inner thread (17). A simple and secure locking of the selected setting of the scribing depth of the scribing tool (9) is achieved, according to the invention, in that the hollow cylinder (19) which forms the head of the spacer (11) and contains the inner thread (17) is designed to be radially resilient. As a result, the inner thread (17) of the hollow cylinder (19) is pressed against the outer thread (15) of the mounting (3) to generate an increased adhesive friction. <IMAGE>
Patent DE-4326173-A1 (DE)
Inventor: SCHWARZ MICHAEL
IPC: G09F3/20
Filed: 1993-08-04
Abstract: A price-indicating cartridge has a bottom part (2) linked by a hinge to a top part (5) that may be folded onto the front side of the bottom part. Information on goods and/or their price is inserted into an intermediate space (12) between the bottom part and the top part. The top part is transparent in the area of said information on the goods and/or their price. In order to stress the number-bearing strips (20) against the top part and to elastically hold them thereon without additional means when the price-indicating cartridge is closed, the intermediate space and the top part are curved around a horizontal axis located behind the price-indicating cartridge. The price-indicating, number-bearing strips (20) are made of an elastically deformable material. The number-bearing strips (20) are thus slightly curved when the price-indicating cartridge is closed, following the curvature of the intermediate space and top part, and are prestressed against the top part because of their elasticity.

Title: Rotation head for crystal-drawing systems for carrying out the Czochralski process
Inventor: SCHULMANN WINFRIED DIPL ING
IPC: C30B15/30
Filed: 1993-08-31
Abstract: A rotation head (11) for Czochralski-type crystal-drawing systems (1) has a reference platform (16), which can be rotated about a vertical rotation axis (A-A), with a vertical passage opening (25) for a pulling member (13) which can be wound up, and a drive unit (23) for driving a horizontal shaft (22). A winding drum (15), having a helical winding groove (29) for the pulling member is mounted rotationally fixed, but capable of being displaced axially, on this shaft. In order to avoid friction and contamination and to obtain accurate guiding of the pulling member (13), a helical guide element (30), having the same pitch as the winding nut and capable of being rotated with the horizontal shaft, is arranged on the horizontal shaft (22) at a location which is away from the vertical rotation axis (A-A). The guide element cooperates with a guide nut (31) in such a way that the part of the pulling member (13) that points tangentially away from the winding drum (15) is guided in the vertical rotation axis (A-A). In this case it is preferable for the helical guide element (30) to be designed as a guide groove and for the guide nut (31) to cooperate via revolving balls (32) with the guide groove. <IMAGE>

Title: Air conditioning plant
Inventor: YOO SI HONG
IPC: F24F3/06
Filed: 1994-03-04
Abstract: The invention relates to an air conditioning plant comprising an external unit and an internal unit, the external unit having an expansion pipe, an external heat exchanger (12), a compressor and a four-way valve, which are connected in series. The external unit furthermore has a heating device (20) for heating a coolant situated in the external heat exchanger (12). In the heating operating mode, a linear-moving element (35) moves in one direction and a transmission device moves simultaneously to pivot lamellae (31). The lamellae (31) are vertically aligned in order to close both an air inlet part (16) and an air outlet part (17) of the external heat exchanger (12). Air heated by the heating device (20) flows upwards with the aid of a fan (44). The heated air flows upwards, in zigzag fashion owing to guiding elements (50, 51, 56), through an air passage (12F, 12B) formed by an interrupting device (30). In the process, the heat is absorbed by the coolant of the external heat exchanger (12) and the air is blown out via an outlet opening after the heat transmission. The air conditioning plant can be operated in the heating operating mode without a coolant having to be supplied by an external heat exchanger (12). <IMAGE>

Title: Method for the production of printed circuit boards
Inventor: OHTANI RYUJI
IPC: B23K26/00
Filed: 1994-08-19
Abstract: A method for the production of printed circuit boards comprises a plating base layer (such as one made of a metal film) being formed on one surface of an insulating substrate, a boundary zone between regions which belong to the circuit and regions which do not belong to the circuit on the insulating substrate being irradiated by an electromagnetic wave such as from a laser in accordance with a pattern of the regions which do not belong to the circuit in order to remove the plating base layer in the regions which are irradiated by the electromagnetic wave, the plating base layer remaining in the non-irradiated regions, and, after this, plating being carried out on the surface of the plating base layer of the non-irradiated regions; this makes it possible to carry out the laser irradiation only with respect to the boundary zone between the regions which belong to the circuit and the regions which do not belong to the circuit without the entire area of the regions which do not belong to the circuit being irradiated, as a result of which the time duration which is required for the irradiation can be considerably shortened. <IMAGE>

Patent DE-4439885-A1 (DE)
Inventor: KERN ROBERT DIPL ING
IPC: H05B41/282
Filed: 1994-11-08
Abstract: A device is proposed for operating a gas discharge lamp (13). The device comprises a power supply circuit which creates an alternating voltage (UL) or alternating current (IL) for a predetermined period (TP) in order to supply the gas discharge lamp (13) with electrical power at a predetermined level. It is proposed that, during a planned reduction of the lamp's mean power in relation to its nominal rating, the instantaneous power within a half period (TP) before the change in polarity of the alternating voltage (UL) or alternating current (IL) should be raised. The duration of the increase in the instantaneous power depends preferably on the period (TP). The device according to the invention for operating a gas-discharge lamp (13) to a large extent prevents the discharge in the lamp from cutting out during the change in polarity and thus ensures re-ignition after the polarity change. A preferred application of the device according to the invention is with a gas-discharge lamp (13) installed in a motor vehicle.
