Title: Improving uniformity of rotary stirring - by auxiliary element and periodically changing flow pattern round stirrer
Inventor: STAHL WERNER DR
IPC: B01F7/16
Filed: 1989-11-07
Abstract: The rotary stirrer mounted on an axial shaft  in known manner in a container for liq and or solids has its action improved by periodical changes in the flow pattern formed by the stirrer.

Title: VHS video-recorder - provides operation in record and replay modes using multiple of nominal tape speed
Inventor: SOWIG HELMUT DIPL ING
IPC: H04N9/825
Filed: 1990-07-10
Abstract: The oblique line recording video recorder is operated in such a way, that `record' and `replay' drive modes are provided at a multiple of the nominal tape speed (2VI), and the tracks (2) are recorded with an intermediate space (3) between them. In a first mode of operation, normal VHS recording is provided, but at double the rated or nominal tape speed. Since no crosstalk occurs between the colour carriers, the previously used comb filter can be dispensed with. In a second variation, the luminance signal and the colour signals are recorded in separate tracks. In a third variation, the tape speed is increased with a track spacing of 98 micrometres, making possible 1, 2, 3 or even 4 track recording, with corresp. smaller track width in each case. USE - For video recorder for high quality recording e.g. D2-MAC, D-MAC, PCM sound etc. using standard VHS or S-VHS construction.

Title: Electrically heated, continuous constant pressure capillary vaporiser - liq. is fed at constant high pressure through high temp. chamber to make it supercritical and flash to vapour when passing through valve
Inventor: BOENIG MATHIAS DIPL CHEM
IPC: F02B3/06
Filed: 1990-07-13
Abstract: Liq. at a constant, elevated pressure is fed from a fixed rate pump through a high temp. chamber, such that the liq. becomes super-critical, and flashes to vapour on passing through a let-down valve, to a lower pressure. A high pressure pump (1) conveys liquid via a feed pipe (2) to a vaporising capillary (3), with an applied voltage across its ends (4). The capillary tube is heated by the electrical current flowing in it. The contained liquid becomes supercritical and is vaporised by flashing across the let-down valve (5) to the precise pressure required. Typical capillary is approx. 3000MM x 0.4MM I.D. x 1.6 O.D., and may be drawn stainless steel. USE/ADVANTAGE - Injection system for diesel fuel. A continuous vapour supply at extremely constant pressure, which may be varied as required.

Patent DE-4100133-A1 (DE)
Inventor: SWARS HELMUT
IPC: F01N3/20
Filed: 1991-01-04
Abstract: The invention relates to a process for electrically preheating a component (2) of a motor vehicle (1), especially an electrically heatable catalytic converter system (2) in which an electric current (1) is applied to the component (2) as a whole for a predeterminable heating period (P). According to the invention, the period (P) is divided into a plurality of partial heating periods (TP1, TP2, TP3) preheating for each partial period (TP1, TP2, TP3) being triggered by an appropriate signal from a sensor (7, 8, 9, 10, 11) or an appropriate logical interlinking of a plurality of sensor signals. The sensors should anticipate starting of the motor vehicle (1) on the basis of a person entering it, e.g. in the form of a seat sensor (7), a seat-belt attachment sensor (8) and/or an ignition switch sensor (9). A probability of imminent starting of the vehicle (1) can be associated with the response of the individual sensors and correlated with a suitable length of the triggered partial heating period. Thus the driver need not waste time waiting for the component (2) to be preheated while at the same time limiting the unnecessary use of electric power.
