Title: Occlusal position carrier
Inventor: WILLNER GERD
IPC: A61C13/34
Filed: 1986-11-27
Abstract: In dental prosthetic practice, the relation between upper and lower jaws corresponding to the physiological conditions must be fixed by the dentist. For this purpose there are various methods, including recording with a writing board and a pen. By means of the occlusal position carrier according to the invention the dentist can provisionally fix the occlusal position as early as the first session immediately after making the impression, so that the dental technician can prepare the functional impression trays which simultaneously serve as carriers of the registration instruments, so that the registration instrument can be assembled correctly in the laboratory. In the second session, registration is carried out after the functional impression, and all clinical measures required of the dentist in patients without teeth are thus finished. The decisive difference from the previously known methods resides in the fact that a complete of impression of the oral cavity does not have to be taken - as has been necessary previously - in the closed state. It is sufficient to take an impression of the relation of the upper and lower dental ridges in the appropriate position with an elastomeric composition.
Patent DE-3642459-A1 (DE)
Title: Laundry drum for a domestic appliance for the washing and/or drying of laundry
Inventor: PORST INGEBORG
IPC: D06F58/38
Filed: 1986-12-12
Abstract: In a known laundry drum for an electrical laundry drier, measuring electrodes coming in contact with the laundry and intended for the moisture control of the drying cycle are mounted on a laundry take-up rib held on the inner circumference of the laundry drum and of approximately V-shaped cross-section. Such an electrode arrangement often gives rise to difficulties, in that a gap can form in the course of time between the measuring electrodes and the outer wall of the laundry take-up rib, the result of this being that a friction edge leading to damage to the laundry occurs. The V-shaped wall part (7, 7', 7'') of the laundry take-up rib (2) is itself designed as a measuring electrode and is fixed in a plastic carrier body (3) fastened to the inner circumference of the laundry drum. In the mounted state of the measuring-electrode wall part (7, 7', 7''), a contact connection, taking place within the V-shaped measuring-electrode wall part (7, 7', 7''), is made with a contact bridge (15, 16) held in the laundry-drum casing (1'). The laundry drum can be used primarily for the drying of laundry in electrical domestic washing and/or drying machines. <IMAGE>

Title: Electrically controllable fibre-optic switch
Inventor: SCHMITT HANS JUERGEN PROF DR R
IPC: G02B6/35
Filed: 1986-12-31
Abstract: The previously known electrically controllable, mechanical fibre-optic switches (so-called fibre-optic relays) use an electromagnet as electromechanical drive. This entails a relatively high electric power requirement of 100-700 mW and leads to slow switching operations of 10-30 ms. The novel fibre-optic relay is to be distinguished by a low operating power and short switching times. Use is made as electromechanical drive of a piezoelectric bimorph strip which bends when an electric voltage is applied and can thus position optical fibres in a pinpointed manner. Since a freely oscillating bimorph strip indicates a strongly oscillating transient response, additional magnetic damping of the movement was undertaken through the use of stops, which consist partly of permanently magnetic material, and of corresponding metal parts on the strip. In order to prevent so-called creep effects in the piezoelectric material, the bimorph strip is driven not by a step voltage function, i.e. two voltage values (e.g. 0 V, 200 V), but by means of a function which decays from a short-term peak value to a lower end value (e.g. 0 V, 200 V = > 120 V) which is obtained with the aid of a low-loss voltage transformer integrated in the relay. The values obtained with a prototype yield a power requirement of 15 mW (5 V/3 mA) for switching times of < 3 ms. Electrically controllable... Original abstract incomplete.

Title: Device for the light-optical (photooptical) display of notices, symbols, special signs (marks), identifying markings and the like, in particular for special-purpose vehicles used by the police, fire brigades, doctors on emergency call, driving schools and the like
Inventor: BIEHL HANS EDMUND
IPC: B60Q1/26
Filed: 1987-03-20
Abstract: The present invention of a "device for the light-optical display of notices, symbols, special signs, identifying markings and the like, in particular for special-purpose vehicles used by the police, fire brigades, doctors on emergency call, driving schools and the like" relates to illuminated displays which are mounted on top of the vehicle transversely with respect to its direction of travel. In this case, the device has a board which, for the purpose of illumination, carries electrical lamps and sockets for said lamps, a hood-shaped part serving the purpose of covering and this part carrying diffusing screens with the notice to be displaced. According to the invention, the display can be cleared by simply switching off the electrical lamps, the diffusing screens of the hood-shaped part on the front side and on the rear side being constructed as an opaque, but translucent projection surface of a back-projection screen (rear-projection screen), and the notice to be displayed being attached directly to the inside of the projection surface or at a small distance therefrom. Since the projection surfaces are opaque, as long as they are not illuminated from inside, the illuminated display can continue to remain mounted on the motor car, if after the particular use (e.g. end of the driving lesson) the previously shown display is no longer permitted to be visible.

Title: Reflecting mat web for greenhouses
Inventor: ARNOLD ROLF
IPC: D04B21/16
Filed: 1987-07-07
Abstract: The invention relates to a reflecting mat web which is produced on the warp-knitting principle by the use of metallised foil strips and which is used in greenhouses for light and heat reflection preferably for screens arranged in a slat-like manner. According to the invention, metallised foil strips, as weft threads having at least four times the width of cut of the stitch-forming threads, are tied in a warp knit by means of right/left fringe-with-weft construction. These foil strips consist of strips of a UV resistant foil with a width of cut of less than 2 mm and are thermoset in their form on the knitting tools. The stitch length amounts to at least 2.3 mm and to at most half the width of cut of the weft threads. The mat web is permeable to water vapour and can absorb dripping water. The sun's rays are reflected diffusely. There is virtually no possibility that ladders will occur.
Patent DE-3728463-A1 (DE)
Inventor: MOELLER JOHANNES ING GRAD
IPC: F15B13/043
Filed: 1987-08-26
Abstract: Control valve devices, in particular for antilock device on pneumatically operatable vehicle brake systems, have a controllable inlet valve (47, 2) and a controllable outlet valve (9, 10). A pressure medium output chamber (3, 7) can be connected via the inlet valve (47, 2) to a pressure medium intake chamber (48, 50) and via the outlet valve (9, 10) to the atmosphere. 
<??>Since, in normal operation (uncontrolled operation), the reduction in pressure in the pressure medium output chamber (3, 7) occurs via the inlet valve (47, 2) and the pressure medium intake chamber (48, 50), the reduction in pressure is considerably delayed. 
<??>In order to overcome this disadvantage and to shorten the times taken for the reduction in pressure, the pressure medium intake chamber (48, 50) is subdivided into a first sub-chamber (48) connected to the inlet valve (47, 2) and a second sub-chamber (50) connected to the pressure medium intake (39), as shown in fig.1. The first sub- chamber (48) and the second sub-chamber (50) can be connected to one another via an additional valve device (38, 42) designed as a non- return valve directable onto the first sub-chamber (48) into the open position. 
<??>By this measure it is ensured that in the event of a reduction in pressure the return flow of pressure medium from the pressure medium output chamber (3, 7) occurs not via the pressure medium intake chamber (48, 50) but via the outlet valve (9, 10) directly into the atmosphere, thereby resulting in an accelerated reduction in pressure in the pressure medium output chamber (3, 7) and hence in the consuming unit.

Filed: 1987-09-23
Abstract: A scarfing machine has a feed roller (1), at least one guide element (13, 14) and a bell-shaped cutter (12) for transporting and guiding raglike parts, especially made of leather or plastic and for applying lateral cuts of a predetermined cross-sectional shape. Servomotors are used to adjust the feed roller (15) and the guide elements (13, 14). An electronic control device (40) is used to store sets of index values corresponding to cross-sectional shapes to permit the positioning of the servomotors and actuation of the servomotors in dependence on such sets of values. A keyboard (37) is provided for inputting sets of values. Means are used for combining groups of sets of values and for the sequential setting of the servomotors using the sets of values of a group. In order to design the scarfing machine (10) so that it can be more easily set up by a user, sets of values can be processed in a more clearly visible fashion and incorrect settings and incorrect processing are avoided, the electronic control device is connected to a motor (23), on the screen (24) of which the sets can be displayed graphically as sectional drawings and numerically as numerical values (Fig. 1). <IMAGE>

Title: Circuit arrangement for operating one or more low-pressure discharge lamps
IPC: H05B41/285
Filed: 1987-12-21
Abstract: A circuit arrangement for operating one or more low-pressure discharge lamps (L, L') having heatable electrodes (E1, E2, E1', E2') contains an invertor (W) which is turned off when one of the lamps (L, L') does not ignite after a plurality of failed attempts at starting. Turning off is performed by switching a thyristor (B) over from the non-conductive operating state into the conductive turn-off state. After a defective lamp (L, L') has been replaced, the thyristor (B) is to be changed over immediately again into the non-conductive operating state. For this purpose, a heating terminal (A2, A'2) of one of the electrodes (E1, E'1) of each discharge lamp (L, L') is connected to the positive pole of the DC voltage source (G). The other heating terminal (A1, A'1) of the abovementioned electrodes (E1, E'1) of each discharge lamp (L, L') is connected to the negative pole of the DC voltage source (G) via a charging resistor (R8), and to the cathode terminal of the thyristor (B) via a surge capacitor (C6). The cathode terminal of the thyristor (B) is, in addition, connected to the negative pole of the DC voltage source (G) via a resistor (R5) or an inductor. <IMAGE>

Title: Linear potentiometer which is operated under oil
Inventor: HAEUSSER HERBERT
IPC: H01C10/38
Filed: 1987-12-24
Abstract: The invention relates to a linear potentiometer which is operated under oil, especially for hydraulic cylinders having internally located path deformation, a wiper being used for the potentiometer pick-off. It has been found that the tongues of the wiper tend to lift off at high speeds, which leads to disturbances in operation. This is supposedly caused by the dynamic formation of a wedging effect which occurs as a result of the relative speed between the oil and tongue when a tongue is operated in a pulling manner. In the case of opposite movements, that is to say in the case of a pressing method of operation, wear has been found which is greater than that in the case of linear potentiometers which are operated dry. This amazing effect in the case of oil lubrication can be explained by the fact that ram pressures in the sense of excessive contact pressure act on a tongue which runs obliquely in the movement direction. According to the invention, these drawbacks are intended to be avoided by the tongues being arranged inside enclosed cavities which are bounded on the one hand by the linear potentiometer and on the other hand by walls of guide grooves and/or a sliding element which is connected to the wiper and is moved together with it, consists of a non-conductive material and slides on the linear potentiometer. The advantage of such an arrangement is that there is now no longer any relative movement between the wiper and the oil within the cavity, and dynamic effects thus... Original abstract incomplete.
