Title: Teeth cleaning device using floss - has double floss strand tensioned between prongs and held in wedge shaped grooves surrounding base of wedges formed by slit in top of prongs
Inventor: MORSTADT GUENTER
IPC: A61C15/04
Filed: 1992-12-01
Abstract: One piece of floss (36) spans the gap (D) between the two prongs (12,14) at least twice. A loop of floss (36c,36x,36y) at each end is inserted into a groove (18,20) in each of the prongs. The grooves may be angled against the tensioning direction. The groove may be wedge shaped so that when the floss is pulled taut, it wedges itself in and holds fast. The tops of the prongs may have a slit (50) forming the tip of two wedges (52,54). The two loose ends (36x,36y) form a figure of eight through the slit and around the wedges. A magazine for storing the floss may be incorporated into the handle. USE/ADVANTAGE - For cleaning in between teeth. It is simple and cost effective to produce, simple to use and effects very good cleaning.

Title: Video recorder with recording of a PALplus helper signal
Inventor: KLUTH HANS-JUERGEN DIPL ING
IPC: H04N9/82
Filed: 1993-05-21
Abstract: A PALplus signal for a 16 : 9 replay (reproduction, playback) contains during the first and last 72 lines of a picture (image) a so-called helper signal which is not utilised in the case of the 4 : 3 replay in a normal television receiver and is used to produce the full number of lines in the case of replay with 16 : 9. The object is to design a video recorder in such a way that the additional recording of such a PALplus helper signal and of the ambient sound are improved. Following a recording of the conventional image carrier (BT) along a first helical scan (S1), a helper carrier modulated by the helper signal (HS) with suppressed carrier and, during the dead times of the helper signal (HS), a time-compressed PCM sound signal are recorded by means of a second head in a line-sequential fashion in a second helical scan (S2) in accordance with the track-trenching principle. Particularly for VHS or S-VHS video recorders with additional recording of a PALplus signal. <IMAGE>

Title: Forge hardening
Inventor: CLAUBERG RAINER DIPL ING
IPC: C21D1/18
Filed: 1993-06-25
Abstract: To be able to dispense with any soft annealing or hardening after forging in the case of hardenable chrome steels, it is proposed that the workpiece be heated to an austenitising temperature between 900 and 1100 DEG C, preferably between 1000 and 1050 DEG C, after forging cooled down to a temperature below the martensite point and, after the cooling down, tempered to convert the tetragonal martensite into cubic martensite. The microstructure of such hardened forged pieces is uniformly fine-grained and exhibits less edge decarbonisation, and the processing sequence is appreciably simplified.

Title: Device having a focusing optical grating for demultiplexing and/or multiplexing and a method for producing such a grating and for operating such a device
Inventor: MAERZ REINHARD DR
IPC: G02B6/34
Filed: 1993-09-30
Abstract: In the device, the optical grating (1) for demultiplexing and/or multiplexing is constructed in such a manner that it optically images a specific spatial point (10) and another specific spatial point (20) on one another in a specific diffraction arrangement (k1) at a specific centre wavelength ( lambda 1) and optically images a further spatial point (30) and the other spatial point (20) on each other in a further diffraction arrangement (k2) at a further centre wavelength ( lambda 2). This permits wavelength region changeover and channel space changeover (channel spacing changeover, channel separation changeover). A programmable device is obtained by using a reversible optical recording material on which the grating (1) can be recorded. <IMAGE>

Title: Steering system for a vehicle
Inventor: NAGAOKA MITSURU
IPC: B62D6/00
Filed: 1994-03-25
Abstract: A steering system for a vehicle has a first steering wheel mechanism for steering front wheels and/or rear wheels in response to a steering wheel being turned and a second wheel steering mechanism which steers the front wheels or rear wheels independently of the steering wheel. A state control system controls the second wheel steering mechanism in such a way that the actual yawing angle of the vehicle converges with a desired yawing angle, specifically on the basis of a state equation and an output equation with at least the actual yawing angle of the vehicle and an estimated drift angle of the vehicle or its wheels as state variables and calculates the control gain of the state control as control gain properties of the frequency transmission function of the change in the yaw angle of the vehicle by steering the wheels on the basis of a first desired behaviour index for providing stability in the case of fluctuations of the movement characteristic, on the basis of a second desired behaviour index for providing rapid response behaviour and identity and a state equation and an output equation of the vehicle with the steering angle of the wheels as input. At least one of the first and second desired behaviour indices is changed in accordance with the driving state of the vehicle.

Title: Wire reel for a binding device
Inventor: HANAGASAKI HIROSHI
IPC: B65H63/08
Filed: 1994-04-19
Abstract: A wire reel (3) for holding or carrying a binding wire, which contains, on the outsides of at least one of two frame plates, a cut-out portion (15) consisting of a circumferential-wall portion (14) with its centre on the axis of the reel and of a bottom-wall portion (12). An optical sensor detection mark (17) is provided in the cut-out portion (15) in such a way that the mark (17) is applied excentrically to the axis of the reel. The circumferential-wall portion (14) of the cut-out portion (15) is designed as a rotatable axle portion which is carried rotatably by the reel-carrier portion of the binding device. Since the cut-out portion (15) is covered or screened off completely by the reel-carrier portion of the binding device, the optical sensor detection mark provided in the cut-out portion (15) is completely free of influences of the external environment. The rotation of the wire reel (3) can therefore be recorded exactly, in order thereby to avoid operating errors effectively, even when the atmospheric conditions and/or the place of use of the binding device in the open or inside or the like vary. <IMAGE>
