Patent DE-3907334-A1 (DE)
Inventor: GOLDHAMMER ALBERT DIPL ING
IPC: B30B9/30
Filed: 1989-03-08
Abstract: A locking mechanism for a baler door contains an eccentrically mounted locking lever (22), which acts on a shaft (17). The arrangement can he secured by a safety lever (25) in the locked position and which prevents shaft (17) from pivoting. In order to give protection in the case of a power failure or incorrect operation on the part of the user, the invention provides for the locking lever (22) to be freely rotatable with lost motion with respect to shaft (17) by 180 DEG  before it drives the same in both directions. This allows any residual pressure on the door (11) to be accommodated by bolt movement without that movement being transmitted to the operating handle should the switch (28), which should cause the baling ram to back up, fail to operate. <IMAGE>

Title: Eddy current revolution counter serving as tachometer - has bores in bell-shaped eddy current piece accepting wheel dresser
Inventor: SKOPIL ARTHUR
IPC: G01P1/00
Filed: 1989-06-03
Abstract: A magnetic piece (11) - pref. in the form of a ring of alternating magnetisation fixed in a former of plastics material is non-rotatably fixed to the rotating part whose angle of velocity is to be displayed. An eddy current component of electrically conductive material (16) is rotatably mounted coaxially with the magnetic piece for magnetic interaction. The rotation of the component (16), resulting from the eddy currents induced in it (against the force of a return spring), causes the magnetic piece to rotate as well.  The eddy current component has at least two bores (25) near its fixing hub (24) on the same radius of its axis of rotation for the pretration of a wheel dresser. ADVANTAGE -  The eddy-current dome can be taken from the indicator shaft (15) on which it is fitted when repair is required.

Title: Spring acting on sealing surface - has sealing force of tensioning spring controlled by adjustable support, that limits spring displacement when closing valve
Inventor: BRUECKNER RAIMUND
IPC: F16K1/20
Filed: 1989-06-13
Abstract: The seal for a large flap valve consists of a sealing spring (6) and a tensioning spring (7) fixed to either the valve flap or housing (5). On shutting the valve, the springs are displaced from their normal position to a sealing position against a sealing surface (5).  An adjustable support (13) limits the spring displacement and allows the sealing force, exerted by the tensioning spring on the sealing spring, to be controlled. ADVANTAGE - Fine adjustment of sealing force possible.

Abstract: 2.1 If train length signalling devices containing radar devices are used for clear track signalling, it has hitherto been possible for wrong signals to occur. It is the aim that such echo signals should not be processed to form speed values/train lengths which come from other vehicles for which no clear track signalling is to occur. 2.2 Echo signals can be subjected to a range selection by using a modulated radar transmitter (4) which feeds at the same time an antenna (6) directed vertically and an antenna (7) directed obliquely towards the train to be evaluated. The echo signals picked up by one antenna (6) determine the beginning and end of the train; the echo signals from the other, obliquely directed antenna (7) produce the respective train speed. 2.3 Railway safety engineering/clear track signalling. <IMAGE>

Patent DE-4010212-A1 (DE)
Inventor: SCHMIDT GUENTHER DIPL ING
IPC: B60T8/48
Filed: 1990-03-30
Abstract: The descrition relates to a process for finding the coefficient of adhesion  mu  between tyre and road. The braking pressure on an undriven (measuring) wheel of a travelling vehicle is increased until wheel-lock sets in. At the same time the driving torque is increased to the point where the braking force on the measuring wheel and the increased driving torque on the driving wheel on the same side of the vehicle are equal. In addition, an increased driving torque on the second driving wheel must be prevented by braking.

Title: Flue gas desulphurisation - with simultaneous prodn. of alpha-hemi-hydrate
Inventor: HOLZAPFEL THOMAS DR
IPC: B01D53/50
Filed: 1990-04-07
Abstract: Desulphurisation of flue gases from fossil fuel-fired (esp. power station) boiler plant, with simultaneous alpha-hemihydrate formation, is carried out by (i) desulphurising the flue gas in a scrubber stage with circulated aq. scrubbing liq. contg. Ca ions, resulting in dihydrate formation; (ii) withdrawing a substream of scrubbing liq. of predetermined dehydrate concn. from the scrubbing stage and feeding it to a conversion stage, held at above 75 (pref. above 80) deg C, in which alkali metal ions are added in amt. such that alpha-hemihydrate is formed from the dihydrate in a mean dwell time of the substream in this stage of less than 10 hrs.; and (iii) withdrawing the aq. phase contg. the alpha-hemihydrate which is then sepd. and dried. ADVANTAGE - The desulphurisation function of the scrubbing stage is optimised and alpha-hemihydrate is produced in a reproducible and controllable manner so that expensive dihydrate conversion in a special unit is not required.

Title: Container holding device during shaking, centrifuging, etc. - has part of holder which is rigid while the other part is movable toward the container centre
Inventor: GUTZWILLER LAURENT
IPC: B01F11/00
Filed: 1990-05-23
Abstract: A device for holding a container (1) e.g. an Erlenmeyer flask, on a surface (2) of e.g. a rack, for use in equipment for effecting shaking, spinning or centrifugal motion, has holder parts (3a,4) which project above the surface (2) and which contact the outside of the container to fix it in position, the holder parts having spring properties and being attached to the surface (2). The novelty is that (a) some of the holder parts (3a) are rigid and are immovably fixed to the surface (2); and (b) the other holder parts (4), acting in opposition to the holder parts (3a), are movable towards the container centre and are biased in the direction towards the container by a spring force (H) which is greater than the max. prevailing force (F) resulting from the motion. ADVANTAGE - The holder device design reliably prevents destruction, position shifting and oscillation of the container.

Title: Moisture measurement in loosely packed biological filters - in which condenser plates on opposing sides scan each other to form intersecting measuring axes
Inventor: KOTTWITZ MAX A
IPC: G01N27/04
Filed: 1990-07-25
Abstract: Consistent measurement of moisture levels is important to detect areas which decrease the filtering effect. Moisture measurement is realised simultaneously on a number of measuring axes which intersect each other at at least two points. Constant variation of the direction of the measuring axes gives an almost perfect measuring network throughout the filter material. Groups of condenser plates or electrodes are located opposite each other on the walls fo the filter container to ensure the measuring axes cover the whole area and provide many intersecting points on the axes.

IPC: H01J29/28
Filed: 1990-11-14
Abstract: In a process for lacquering the phosphor layer on the bowl of a colour display tube (colour picture tube) screen, the following steps are performed:     - the phosphor layer is first pre-wetted, - a first aqueous dispersion of a lacquer is applied to the pre-wetted phosphor layer, - said first dispersion is completely dried and heated to above the film-forming temperature of the lacquer in order to produce a first lacquer film, - a second aqueous dispersion containing identical components to the first dispersion is applied directly to the first lacquer film, the concentration of the components in the second dispersion being at least essentially equal to the concentration of the components in the first dispersion, and - said second dispersion is completely dried and heated to above the film-forming temperature of the lacquer in order to produce a second lacquer film.   This double lacquering process enables screen brightnesses to be achieved which are about 10% higher than were achievable with the hitherto conventional, single lacquering process. <IMAGE>
