Patent DE-3919153-A1 (DE)
Title: Current adjustment circuit for multipolar magnet coil system - produces equal and opposite changes of current in two quadrupole systems supplied from separate controllable sources
Inventor: GEHRMANN RAINER DIPL ING
IPC: H04N5/228
Filed: 1989-06-12
Abstract: Two quadrupole coil systems (6,7) are arranged at 45 deg. to each other, in the immediate vicinity of the electron gun of a TV camera. Individual orthogonal coils of each system are connected in series so that the magnetic fields of diametrically  opposed coils cancel out. Current is supplied by controllable sources (8,9) with summation and estimation stages (16,17) so that an increase of current in one system of coils (6 or 7) is matched by a corresp. decrease in the other. ADVANTAGE - Scanning flaws can be corrected easily to minimise wavy edges, without ambiguities or reciprocal dependences.

Title: Slide dissolve (change-over, fade) projection method with one projector having one objective or without objective with two parallel drive shafts as well as two special slide magazines
Inventor: NEUWAELDER KURT
IPC: G03B23/18
Filed: 1989-07-22
Abstract: According to the present state of the art, either at least two projectors having one objective each or one projector with two objectives with in each case one slide magazine are required for slide shows with dissolve effects. In the case of the invention, only one projector having one objective and two special slide magazines is instead required in most cases. The solution is, that the projector having one objective contains two parallel drive shafts (1) with mutually offset slide grippers (2) and dissolve-effect screens (3) as well as special slide magazines (4) outside the drive shafts (1) in the slide-gripper area and that the slide grippers (2) grip the slides at the lower section of the front edge (5 and 6) of the mounts. The offset between slide grippers (2) and special slide magazines (4), and the slide catch (5 and 6) have the result that the slides are located congruently in the slide stage (7). The slide grippers with slides (5 and 7) and the dissolve-effect screens (3) can be moved for the purpose of any desired dissolve effects by the drive shaft control (1). This solution, namely, to present slide shows with dissolve effects only with one projector having one objective and two special slide magazines, results in savings in terms of projectors, accessories, and work and considerable reductions in costs, which in itself may cause this popular hobby to spread even further. <IMAGE>

Abstract: "Vulcameter" (cure test appts. for elastomers) tests are made with a closed (or closable) mould cavity for a test moulding by injecting the material and subjecting it to high temp. and shear or torsional stress, then measuring deformation resistance against time. More specifically, a conventionally mounted mould has a cavity (1) to produce the test piece (2) of elastomer between the top (3) and lower (4) tools.

It is useful to enclose the mould system in a sealed chamber containing slightly pressurised and cleaned air. This chamber has a top (10) and bottom (11) cover and is arranged to open when the mould opens. The split line (12) between its top (10) and bottom (11) halves is at the same level as that (8) of the cavity (1). ADVANTAGE - The method does not require test pieces to be produced beforehand. It provides accurate tests and is simple to perform.

Inventor: OHLSSON THOMAS
IPC: A61B5/308
Filed: 1991-03-04
Abstract: In a known circuit arrangement, each of several physiological measurement signal sensing electrodes (1, 2, 3) is connected to a first input of an input amplifier associated to said electrode, whereas the second input of the input amplifiers (4, 5, 6) is connected to a common reference potential (7).

Title: Reheating gaseous media in flue gas desulphurisation reactors - esp. for coal-fired power stations, using turbine pass-out stream for indirect contact heating of fluidised bed
Inventor: SCHULZE HERBERT DR ING
IPC: B01D53/50
Filed: 1991-04-02
Abstract: The gaseous medium is treated by contacting with additives, and following a period of desulphurisation in a reactor, the coarse particulates are taken-up and separated by a fluidised bed on the flow of the reactor. Novelty is that the fluidised bed, which is provided with a submerged heating surface, is back-flushed by fluidising with purified smoke gas, that the submerged heating surface is warmed by pass-out steam from an associated power turbine, and that the precipitated coax particulates are blown from the edge zone of the bed in the direction of the funnel shaped centre of the bed, and/or moved tangentially to the funnel wall towards the centre. ADVANTAGE - Total dirty smoke flow from the furnace can be put to the absorber, without the need to split the flow to provide recalorification of the treated portion of the smoke at the stack. Additional capital equipment downstream of the absorber is not required. Heating of the treated smoke gases is energy efficient. Pptd. damp particulates are dried in the fluidised bed, avoiding fouling by surface bake-on. Ash removal follows without the need for mechanical devices. The funnel reactor can be free-standing.
