Patent DE-3934180-A1 (DE)
Title: Lens grinding mount - with backing element of silicone rubber for absence of deformation and vibration
Inventor: WATANABE MASAKI
IPC: B24B13/005
Filed: 1989-10-13
Abstract: The holding fixture (111) on a grinding machine for grinding a lens (113) includes a mount (112) and a reception element (114), made of silicone rubber. A recess (112b) is required for a coupling of the grinder. The hemispherical knobs (116) on the element (114) contact the lens evenly and are deformed by the grinding pressure, resulting in a uniform load on the lens which will be free from deformation, even when the lens is thin. The element (114) is produced by injection moulding. ADVANTAGE - This eliminates lens vibration and deformation even with high grinding pressures.

Patent DE-4016698-A1 (DE)
Inventor: EIDLING KARL
IPC: H05K13/04
Filed: 1990-05-23
Abstract: The production of light-emitting diode rows (LED-rows) for non-mechanical printers requires an exact positioning of the LEDs (1) on a modular plate (3). Since each LED row is composed of several LEDs (1) arranged in a row, an exact positioning of the LEDs (1) in relation to each other and to the modular plate (3) is required. The clearance limits lie around +/- 3 to 10  mu m. In order to obtain a process with as few operations as possible that ensures an exact positioning and a soft handling of the LEDs (1), an auxiliary carrier designed as a sucking carrier (2) is disclosed. Each sucking chamber (6) which it contains retains one LED (1) by negative pressure. The use of the sucking carrier (2) makes it possible to dispense with wet-chemical processes and mechanical cleaning processes to remove the auxiliary carrier from the LEDs (1). When the sucking carrier (2) and the modular plate (3) are heated, soldering can be carried out in a very short time without expensive soldering installations, in a holding fixture and under constant inspection by means of a measurement microscope (5).

Inventor: BAUERSCHMIDT WERNER DIPL ING
IPC: H04M1/72502
Filed: 1990-11-15
Abstract: Radio transceivers for an FDM-TDM radio transmission system are known in which data are transmitted via a pair of radio channels using the time division multiplex method. For duplex operation, constant high-speed changeover between send and receive mode is required. No residual signals originating in the transmitter may be present in receive mode, since these would deceptively simulate a receive signal. Total de-activation of transmission frequency processing is impossible, since the delay between re-activation and attainment of high frequency precision is too long. 
<??>In the radio transceiver according to the invention, a first auxiliary oscillator, which is connected to the transmission mixer, is disposed in the transmission device, and the transmission path between the transmission mixer and the main oscillator is interrupted in receive mode by a switching device. De-activation of the transmission frequency can also be achieved by the switching device interrupting the transmission path between the transmission mixer and the first auxiliary oscillator or between the transmission mixer and the power supply device of the radio transceiver.

Title: Auto-vegetative propagation of beech - by placing cuttings in thin top bed layer to form adventitious roots which rapidly pass lower humus-rich layer
Inventor: EBERHARDT ERNST DR
IPC: A01G7/00
Filed: 1991-02-04
Abstract: Auto vegetative reproduction of beeches in multi-layered plant beds comprises (a) keeping cuttings in a strongly defined top bed layer with low thickness in an initial phase, so that adventive roots are formed; (b) forcing the adventive roots through the top layer into the subsequent humus-rich and nutrient-rich foundation layer; (c) generously providing the developing buds of the cuttings capable of forming strong roots with nutrients; (d) placing the cuttings which have been generously provided with nutrients in the soil in order to develop leaves in the next year. USE/ADVANTAGE - The process gives high rooting and leaf development quotients in the following year. The adventive roots grow as early as possible into the tree nursery soil which has been enriched with humus and nutrients so that intensive formation of the whole root system is achieved. The sprouting quotient is high, more than 4-5 times that using known processes with the longitudinal growth of shoots in the first vegetation period (i.e. the first year after planting the cuttings) being on average 50-70 cm, with max. shoot length over 1 m. The average root growth of the one year old plants is on average 40-60 cm, which is better than that of normal three year old plants. The top bed layer is pref. 4-6 cm in thickness and is composed of a peat-sand mixt., or is a mineral wool layer also of thickness 4-6 cm, esp. made up of mineral wool cubes of sides 6 cm.

Title: Eliminating internal error effects in dual channel, non-dispersive absorption photometer - sampling amplitude of detector output signal, and pulse shaping with synchronisation to specific phase angle of detector output signal
Inventor: BREIER JOACHIM DR
IPC: G01N21/3504
Filed: 1991-08-28
Abstract: The method of eliminating internal error influences on the static transfer characteristic involves sampling the amplitude of the output signal of a detector with a signal period specific to the equipment and at a suitable position. Pulse shaping is performed using the sampled amplitude. The signal sampling and pulse shaping are synchronised with a defined detector output signal phase angle chosen to minimise synchronisation errors. Synchronisation triggering involves detecting a mark on a chopper disc. The fundamental or a harmonic in the pulse signal is processed to yield a concentrated image signal. USE/ADVANTAGE - For photometers with chopper amplitude modulation. Static characteristic is maintained approximate to Lambert-Beer characteristic despite structural and adjustment effects.
