Patent EP-0044666-A2 (EP)
Inventor: BROWN HARVEY A
IPC: C09K19/60
Filed: 1981-07-08
Abstract: A composition for use with liquid crystal compositions in liquid crystal display devices, which possesses both a chromophoric moiety and a helical ordering moiety. The helical ordering moiety is capable of helically ordering a mixture of liquid crystal material and helichromic compound. The helichromic compound can be utilized in conventional "guest-host" and "twist nematic" displays as well as in unique helichromic displays. When used in helichromic displays, the helichromic compounds eliminate after-image scattering and enable the display to be operated at reduced voltages.

Abstract: A process for catalytically converting carbonaceous materials is described using a metal hydrogenation catalyst whose activity is reduced during the catalytic conversion. The reduced activity catalyst is dissolved in a leach solution to form a catalytic metal salt solution. Hydrogen is contacted with the solution so that active catalyst metal is precipitated from the leach solution. The dissolution and reduction steps are continuously effected such that the reduced activity catalyst is continuously converted to an active precipitated metal catalyst. A continuous process for the production of a catalyst mixture of at least two metal catalysts is also described using the same procedure.

Abstract: An FET dynamic RAM array has one-FET-device cells (4) each associated with a respective bit line portion, there being two bit line portions, each associated with a respective node (N2) of the sense amplifier (3) by two FET switches operated by V (TOP) and V (BOTTOM). Capacitors (6) in the cells are charged according to the information they store. Cells are accessed by raising the potential of a word line e.g. WORD n for the cell with capacitor Cn, 1. If at that time capacitor Cn+1, stores a «1», and if BIT LINE L (BOTTOM) is at ground, the drain-source voltage of the associated FET (5) may force it to conduct so that the stored information is lost. This is prevented by V (BOTTOM) turning off L (BOTTOM) while the potential on BIT LINE L (BOTTOM) is at the precharge level (approximately V DD  caused by OPC. The array is single-polysilicon, in which portions of word lines are used as cell capacitor electrodes.

Abstract: An out of proximity alarm system useful for indicating when the distance between two bodies has increased beyond a predetermined distance is disclosed. In the preferred embodiment, the system comprises a radio transmitter attachable to one of the bodies, such as a personal article such as a briefcase and having a pulsed R.F. output. A radio receiver carried by a second body, such as a person, receives the transmitted signal when the two bodies are within range of each other. The receiver incorporates a time delay stage which is kept disabled by the received pulsed signal. Should the distance between the two bodies increase beyond a predetermined amount the pulsed signal will have insufficient strength to keep the time delay stage disabled, thus activating an alarm and alerting the carrier of the receiver that he has left the personal article behind.

Abstract: HF-amplifier device comprising a first transistor which is controlled at its base by a signal source and whose collector is connected to a load, also comprising a second transistor for compensating for the distortion occurring in the first transistor. According to the invention, this distortion is measured by comparing the collector output voltage of the first transistor with the collector voltage of a so-called third transistor, which is highly linearized by means of negative emitter feedback and which evidences a similar voltage gain as the first transistor and whose base is coupled to the base of the first transistor. Said distortion is thereafter compensated for in the forward direction by using the collector difference voltage of the first and third transistor as a control voltage for a second transistor which is connected to the load as an emitter follower. This results at the same time in a low output impedance of the HF-amplifier device.
