Title: Video recorder timing error rectifier - smooths luminance signal and colour carrier and reduces interfering folding and modulation products
Inventor: KLUTH HANS-JUERGEN DIPL ING
IPC: H04N9/83
Filed: 1992-06-03
Abstract: The video recorder records a picture carrier (BT) frequency modulated with a luminance signal (Y) and a colour carrier (Fm) reduced in frequency. On recording, the luminance signal is first frequency modulated onto a modified picture carrier (BTm) whose frequency is higher than that of the picture carrier. The frequency of the modified carrier is converted to the picture carrier frequency with a mixer carrier (M1) from the line sync. pulse (S). On playback, the carrier scanned on the tape is converted to a higher frequency modified carrier with the mixer carrier from the sync. pulse. This is fed to an FM demodulator (19) tuned to this frequency to supply the luminance signal. USE/ADVANTAGE - Esp. for video recorders with high signal qualities. Simple, inexpensive circuit which reduces timing errors of luminance signal and colour carrier on playback and reduces interference.

Patent DE-4300171-A1 (DE)
Title: Device for securing pinching and shearing locations, in particular for force-actuated windows, doors and gates
Inventor: PFEFFER WALTER
IPC: F16P3/12
Filed: 1993-01-01
Abstract: In the case of force-actuated windows, doors and gates, e.g. in the case of car parks, it is necessary to make provision for special devices which secure pinching and shearing locations and prevent injury to people and animals. The simplest way of protecting relatively long closure or shearing edges is to mount pneumatic contact hoses which are sealed on both sides and, by means of a pneumatic membrane switch, immediately switch off the drive power in the case of contact, i.e. in the event of danger. A practical problem is the detection of a fault when, by way of damage or porosity, the pressure hose loses its leak-tightness and thus becomes incapable of efficient functioning. This can be achieved, only partially, with a relatively large degree of technical outlay, thus resulting in a considerable remaining risk being unavoidable. These disadvantages are eliminated according to the invention in that, according to Patent Claim 1), a superatmospheric pressure is maintained in the pressure hose and a monitoring switch is switched through by means of the same. If, for example, by way of porosity, there is a drop in pressure in the contact hose, said switch drops back again, interrupts the control line of the drive motor and triggers an alarm. A further advantage of the invention is that the numerous existing system can be brought to the permanently self-monitoring 100% safety level according to the invention by exchanging a small number of parts.

Title: Device for handling and operating brushes, preferably toothbrushes
Inventor: KELL GERHARD
IPC: A61C17/34
Filed: 1993-02-09
Abstract: The invention relates to devices for handling and operating brushes, preferably toothbrushes, which represent an advanced alternative to the conventional brushes and dental hygiene means, both in terms of use and in terms of expenditure. The manually operated cleaning and brushing devices preferably meet the ecological requirements for saving of electrical energy. A modular system in which brushes, brush units and operating means are expediently combined in design and practice is claimed. The concepts shown in Figures 1 to 10 offer manually operated devices which the operating axle drives in stroke intervals by means of a pistol-shaped handle and counteracting spring force in Figs. 1-3, whereas in Figures 4 to 6 the operating axle drives the brush unit, or only the brushes, by means of a "screw drive". The devices which are driven axially radially (translationally) by lifting elements (Figs. 7-10 and Figs. 11-13) have the advantage that the brush unit and the brushes can be activated and moved simultaneously. The envisaged exchangeability of the individual brush elements is another economic and ecological advantage of the innovation.
