Title: Low-noise, low-distortion multiplex demodulator circuit - has signal level holding capacitors between switching and output stages
Inventor: NUMATA TATSUO
IPC: H04J3/02
Filed: 1979-07-06
Abstract: The multiplex demodulator circuit is designed to have a higher signal/noise ratio and reduced distortion. The circuit comprises an input buffer amplifier (1) whose output is connected to a switching circuit (2) to which the 38 kHz signal is applied. The switching circuit consists of two FETs operating in opposite phase. Alternatively, CMOS devices may be used. The outputs are connected via resistors and capacitors (C1, C2) to operational amplifiers (3, 4) which provide the left-channel and right-channel output signals. The capacitors represent a hold circuit (8) which holds the level of the demodulated output signal to the level it was immediately before the signal path to the output amplifiers was interrupted by the transistor switches.

Title: PAL receiver picture focussing circuit - uses digitally mixed chrominance and luminance signals and scanning frequency based on carrier frequency
Inventor: DEMMER WALTER ING GRAD
IPC: H04N9/78
Filed: 1979-09-29
Abstract: The method of improving the focussing of the image signals for a 03L TV receiver increases the sharpness around the edges of the screen. The amplitudes of brightness signals are adjusted without affecting the colour signals or phase distortion. Two frequency bands are separated from the luminance and chrominance signals, mixed digitally and passes through a filter network. A scanning frequency is used which is double or some other whole number times the carrier frequency. The base signal is obtained from a digital transverse filter with symmetrical coefficients which can be adjusted, and is the luminance signal. The luminance filter uses two filters with adjustable coefficients, and a normalising multiplier. The chrominance filter uses two filters and a bridging filter. The filter coefficients involve simple trigonometric functions of the frequency.

Title: Light transmission measurement of defined flow sections - is done during measurement periods defined by measurement of electrical conductivity
Inventor: ZINKL WALTER
IPC: A61B5/145
Filed: 1980-05-09
Abstract: The method of measuring the light transmitting properties of defined parts of a continuous flow contg. regions of bubbles and liquid is esp. applicable to determining blood groups. It is me more accurate, reliable and economical than conventional methods. The electrical conductivity of the flow is measured and used to control the measurement of light transmission in the defined flow section. The light transmission measurement takes place during a period of content electrical conductivity above a minimum level. The beginning and end of the measurement period are defined by an optional number of periodically detected equal conductivity measurements taken before the beginning and after the end of the period. Optical fibres are used for the measurement of transmission which takes place in the upper region of the flow cross-section.

Title: Differential with four wheel drive selection - has axially moving control rod with stop
Inventor: FRIEDRICH KARL
IPC: B60K17/346
Filed: 1980-09-25
Abstract: The selection control for a four wheel drive differential has a shift rod moving into one of four settings, with three of the settings controlled by a hand selector lever. The middle setting represents a neutral setting in which the driver can touch the accelerator in order to aid the synchromesh when moving into four wheel drive. The fourth setting is selected by a pneumatic servo, and serves to lock the differential in four wheel drive. The hand control provides a precise control for the driver. The self locking effect of the differential, in four wheel drive setting, occurs in response to wheel spin sensors and enables the vehicle to negotiate heavy going.

Title: Combined lens and reflector system - for multi:path spectroscopic or photochemical processes with low absorption gases
Inventor: KLEMENT EKKEHARD DIPL PHYS DR
IPC: G02B27/10
Filed: 1980-09-29
Abstract: Spectroscopic investigations or photo-chemical processes in a gaseous absorbing medium utilises a folded path device form of two lenses and two deviating mirrors, these mirrors being either prisms or triple-mirror units, in either case with total internal reflection. Light rays pass repeatedly through the device along a series of closely adjacent paths. The apex of the prism or triple-mirror unit is slightly offset from the optical axis of the combined lenses, which both have the same focal length and are confocally arranged. All light-transmitting surfaces are bloomed to reduce light loss. The absorbent specimen is encountered by the light beam at a modal point, pref. the basic model point of the device. When pulsed light is used, the optical path length in a full transit of the device is the same length as an individual wave train. Used esp. for pulsed laser investigation or treatment of small vol. streams of gas with low absorption. The repeated light passes utilise the light supply more effectively.
