Patent DE-3732878-A1 (DE)
Inventor: SCHMIDT THOMAS DIPL ING
IPC: B60R22/46
Filed: 1987-09-30
Abstract: The tightening device has a cable drive 12 actuatable in the event of a crash. The cable pulley 11 is connectible to belt winding shaft 10 of the belt reeling device via a locking member 14. The latter is eccentrically mounted on the cable pulley and has teeth 15 thereon which can be brought into engagement with circumferential teeth 17 (locking position) on thrust ring 16 connected with the belt winding shaft 10. The locking member 14 is biased by a leaf spring 20 towards the locking position but is held in its initial rest position shown by an arm (23, Fig 2) on a spring ring 22. Relative movement between the cable pulley 11 and housing displaces the arm (23) to thereby allow pin 18 to move along slot 19 and enable the locking member (14) to be moved into its locking position. In an alternative arrangement (Figs 5 and 6), a radial resilient arm (26) cooperates with an annular ratchet (28) to hold the locking member (14) in its rest position. <IMAGE>

Patent DE-3735842-A1 (DE)
Title: Tool
Inventor: MANKERTZ OTTO DIPL ING
IPC: B27G13/02
Filed: 1987-10-23
Abstract: A tool for machining workpieces, in particular wood, having a rotatably driven cutter block and a workpiece-bearing member through whose at least one slot during the machining at least one cutter of the cutter block engages, is distinguished according to the invention in that the workpiece-bearing member is constructed as a hollow-cylindrical shell which concentrically surrounds the cutter block and is or can be connected to the latter so as to be fixed in terms of rotation, and in that for each cutter of the cutter block the shell has a slot which is stationarily adjacently assigned to the respective cutter. Such a tool is extremely easy to handle and versatile, being able to produce, for example, concave depressions in any surfaces. If, moreover, the shell as is preferable is constructed flexibly and/or is mounted flexibly, the chip depth can be varied during operation merely by changing the applied pressure against the workpiece.
Patent DE-3738038-A1 (DE)
Inventor: KOELBLIN KARL
IPC: B41F15/36
Filed: 1987-11-09
Abstract: Known screen printing machines in which the screen frame is subjected to a lifting movement behind the traversing squeegee cannot be used for a screen printing activity in which the squeegee runs in the reverse direction without disadvantages arising. 
<??>It is therefore proposed to arrange the swivel axis for the screen frame through the central plane of the screen frame running vertically to the squeegee movement and in each case to provide devices which are able to lift the screen frame on both sides of the swivel axis. This configuration permits use of the screen printing machine for movements of the squeegee in both directions while retaining the advantages of a compensation for print faults. 
<??>The new screen printing machine is particularly suitable for the printing of circuit boards.

Title: Travelling and guiding castor
Inventor: ENGLAND WILHELM
IPC: B60B33/00
Filed: 1988-02-12
Abstract: A travelling and guiding castor (2) is guided along a rail (1). The spindle (6) of said castor is mounted on a wheel holder (7) of an industrial robot which is not shown in more detail. The travelling and guiding castor (2) has a spherical travelling surface (3) and on that side which is opposite the wheel holder (7) has an insertion groove (4) for a drive ring (5). This drive ring rests on the rail (1) when the travelling and guiding castor is unloaded even when there is an air gap between the rail and the travelling surface (3) and causes the travelling and guiding castor to rotate, the castor resting on the rail (1) when it is loaded and hence deforming the flexible drive ring (5). <IMAGE>
Patent DE-3809109-A1 (DE)
Title: Device for air mass measurement
Inventor: SASS WOLFGANG DIPL ING
IPC: G01F1/698
Filed: 1988-03-18
Abstract: A device for air mass measurement, especially in motor vehicles with internal combustion engines, has a measuring bridge in one branch of which a resistor (especially a hot-film sensor) washed by the air flow is in series with a measuring resistor and in the other branch of which a compensating resistor detecting the air temperature is in series with a fixed resistor. The bridge difference voltage in the null branch of the measuring bridge is measured and the signal resulting therefrom is used to control a transistor valve in the bridge supply path of a bridge supply source, the transistor emitter being connected to the bridge and the control being effected via the transistor base to balance the bridge, and the voltage across the measuring resistor after balancing the bridge is evaluated as a measure of the air flow. It is suggested according to the invention that the transistor valve is designed as an npn-transistor switching off in the case of negative voltage peaks in the bridge supply voltage. It is achieved by these measures that in the case of negative voltage peaks on the supply lead the transistor valve temporarily closes further and overheating of the measuring bridge is avoided. Such overheating would lead to the detection of an excessive air mass flow and thus for example to a dangerous enrichment of a fuel-air mixture (instead of this, the negative voltage peaks result in a harmless temporary leaning of the mixture).

Title: Mobile container for waste materials (glass, cans, paper, etc.)
Inventor: DRIGNATH ROLAND
IPC: B65F1/14
Filed: 1988-05-20
Abstract: The invention relates to a container which, especially in conjunction with a clamp-on transport roller, permits the mobile transportation of waste materials to the container collection point for recycling. Moreover, the transportation of the container can optionally take place by hand or, for example, by means of a motor vehicle, moped or bicycle. Hitherto, the waste materials have been taken to the central collection point in, for example, bags, carrier bags and cartons, older people without motor transport having been particularly severely effected by the load to be carried, which is not always light. To solve this problem, the invention envisages a waste material container whose fixing device consists of a rail attachment and in which slide-in clamps are provided for receiving a travelling linkage. Further fixing is provided by two supporting feet of the container which are inserted into sleeves attached to the wheel axle of a special transport roller prepared for fixing the container. Individual receiving containers in the transport container, provided with supporting shackles, can receive the waste materials, consisting of various substances, in a separated and a pre-sorted manner.

IPC: B60J7/00
Filed: 1988-05-20
Abstract: A sliding roof for a passenger car has a frame for the inside roof lining which does not need to be lifted in order to retract the sliding roof. To ensure that the lower surface of the frame is essentially flush with the lower surface of the inside roof lining when the roof is closed, without having to provide a lifting mechanism for the frame so that the sliding roof can be retracted as desired, the frame (7) has raised edges ridges (8) along its front and side edges, which ensure that the frame (7) is flush with the inner roof lining (4) of the vehicle when the sliding roof (3) is closed, and the rear edge (9) of the frame (7) is essentially flat and overlaps the corresponding edge of the inner roof lining (4) of the vehicle. As a result, the frame (7) can be retracted, together with the sliding roof (3), without being lifted.

Title: Phase-controlled antenna array
Inventor: DONDL PETER DIPL ING
IPC: H01Q3/38
Filed: 1988-06-06
Abstract: In the case of phase-controlled antenna arrays whose main beam direction and/or focusing is varied by driving the individual radiating elements or the individual radiating element groups in a phase-shifted manner, in order to be able to dispense with dynamically adjustable phase shifters, because of their structural size, a dedicated (large-scale integrated) modulation device is assigned to each individual radiating element or to each group of individual radiating elements. In this case, a control device supplies all the modulation devices involved either with the information on the respectively correct phase angle or with the respective oscillation itself in the correct phase, so that the main beam of the antenna can be aligned, pivoted or focused as the resultant of the beams from the individual radiating elements. In order to be able to transmit different signals in different directions using the same antenna, a plurality of modulation devices acts on in each case one individual radiating element or a group of individual radiating elements. If the output power of the modulators is sufficient, it is possible to dispense with transmission power amplifiers.

Title: Process for producing a workpiece and a tooth model
Inventor: SCHULZ BERNHARD PETER
IPC: A61C13/34
Filed: 1988-08-16
Abstract: A tooth model (11') of thermoset material comprises a basic body (12'), corresponding approximately in hardness and colouring to the dental pulp, a first coating (13'), applied to the said basic body and corresponding approximately in hardness and colouring to the dentin, and a second coating (14'), applied to the said first coating and corresponding approximately in hardness and colouring to the tooth melt. The basic body (12') and also the first and second coatings are produced from an injection-mouldable or transfer-mouldable thermoset material. The tooth model (11') consequently corresponds to the natural structure of a tooth. During practise work, it can easily be seen from the different colourings of the individual layers in which region for example drilling is being carried out, and also feeling can be trained, since the individual layers can be differently adjusted in their degrees of hardness to correspond to reality. <IMAGE>
Patent DE-3833800-A1 (DE)
Title: Water overflow protection, in particular for domestic dishwashers
Inventor: KAEFFERLEIN HEINZ
IPC: D06F39/08
Filed: 1988-10-05
Abstract: Overflow protection must prevent water damage. It has to be ensured here that actuation does not occur in the event a functionally induced water discharge, even if this has been caused by improper operation. In dishwashers on the market, the overflow protection of the appliance can be put out of action after inadmissible opening and closing of the door during operation. In the arrangement according to the invention, this is prevented and the user is spared unnecessary repairs. The pressure-monitor vessel (4) has a safety overflow edge (14) for a water-collecting chamber (16) which leads into the base pan (21) only via a further overflow edge (18) and its overflow (19, 20). If the door is opened in the hot state of the appliance during the rinsing operation, a positive-pressure surge arises in the interior of the appliance when the door is closed. The positive-pressure surge directs a quantity of liquid via the normal-level overflow edge (11) into the water-collecting chamber (16). It remains in it and evaporates as a result of the high internal temperatures. The water overflow protection is especially suitable for domestic dishwashers. The principle can also be used in washing machines. <IMAGE>

Title: Device for controlling the conveying pressure in planetary-gear extruders
Inventor: KRETSCHMAR HANS-WOLF DIPL ING
IPC: B29C48/44
Filed: 1988-10-11
Abstract: The invention relates to a device for controlling the conveying pressure and dwell time of polymer melts in planetary-gear extruders, in particular planetary-gear extruders as the first cascade stage of a cascade extruder, which permits controlling which is favourable in conveying terms and can be varied in fine stages. According to the invention, this controlling takes place by means of a known thrust ring and an exchangeable washer arranged in the latter. The annular slot face of varying distance formed between thrust ring and washer controls the discharge of the polymer melts and causes additional friction and also an increase in the surface area of this melt, in order to degas the latter effectively in the duct which follows and also to homogenise it in the discharge extruder.
Patent DE-3836759-A1 (DE)
Title: Catalyst for activating molecular oxygen
IPC: B01J31/18
Filed: 1988-10-28
Abstract: The invention relates to a catalyst for activating molecular oxygen which is to be exposed to the action of a radiation source. The activation energy is transmitted via a photosensitiser which has at least one chromophoric group. Known catalysts of this type are produced by converting the photosensitiser into a solid state by chemical reactions with a binder. It must be used in a very fine-grain state so that it can be separated off again from the reaction medium later by filtration. This is prevented according to the invention by the sensitiser exposed to radiation and the molecular oxygen being formed by a pigment of at least one dye of the group including phthalocyanines on the one hand and diazotised  beta -naphthol on the other hand. Such pigments do not need to be first converted into a solid state, but they can be used directly for heterogeneous catalysis. Their non-toxicity permits the use of oxygen activated therewith for medical purposes.
