Title: Printing mechanism for a typewriter or office machine of similar design
Inventor: GERKEN HEINER DIPL ING
IPC: B41J1/24
Filed: 1989-02-01
Abstract: The frequent change to foreign languages with different characters or to different type faces with specific formulae requires easy exchangeability of the daisywheel (8) in printing mechanisms in typewriters or similar office machines. The daisywheel (8) is fitted onto the free end of a drive shaft, it being possible for the daisywheel (8) to be coupled to the wheel receiver (15) via a carrier pin (21). The engagement of said carrier pin (21) in an engagement opening (23) in the daisywheel (8) takes place only in their common flush position, which is achieved by means of a search run of the wheel receiver (15). According to the invention, this engagement is simplified by the fact that the daisywheel (8) is blocked by a blocking member during the search run movement. According to the invention, the blocking member is a control rocker (27) which is mounted pivotably on the printing mechanism carriage (6), can be disengaged from its catch position by means of a holding member (29) which can be pivoted by means of and during the pivoting of the pivoting bearing (28) into the operating position, and can be brought by a blocking lug (26) into the range of action of a stop (25) on the rotating daisywheel (8) in such a way that the carrier pin (21) engages securely in the engagement opening (23) to be carried along in rotation while the daisywheel (8) is blocked and then blocks the drive motor (9) of the daisywheel (5). After blocking of the drive motor (9), a control device (30) then emits drive pulses to a drive motor (31) for the printing mechanism carriage (6) in such a way that the...

Title: Absorption cuvette for optical gas-testing in bore - for elongated optical fibre with gas transfer surfaces
Inventor: DOBOS KAROLY DR
IPC: G01N21/3504
Filed: 1989-06-30
Abstract: A cuvette for measuring gas concn. by optical absorption, esp.  of IR light, with repeated internal reflection, is formed as a capillary bore inside an optical fibre. The fibre sheath may be porous or otherwise provided with multiple small apertures by which gas can constantly enter and lead the capillary bore.

Inventor: SATO KOUICHI
IPC: H04N5/93
Filed: 1989-09-13
Abstract: A mode discriminating device which discriminates between a normal mode and a high-band mode RF video signal reproduced from the disc of a still video camera, comprises only one band pass filter 21 having a central frequency set in the high-band or normal mode carrier frequency band. The output of the filter is smoothed 22 and compared with a reference voltage. The reproduced output is also smoothed 13 and compared 14 with another reference voltage to thereby detect the presence of one of the high-band or normal mode carriers. The outputs of the comparators are ANDED 25 to provide the discriminating signal. If the reproduction level is too low and/or the noise level is too high, a mute signal is used in determining the discriminating signal so that an erroneous detection thereof is not carried out. <IMAGE>

Title: Mould for ribbed cylinders - has durable upper mould section and lower support section for structured and even cooling
Inventor: DALEWSKI GUENTER DIPL ING
IPC: B22C9/26
Filed: 1990-06-27
Abstract: The mould (2) for casting ribbed cylinders (1) is divided on a line at about right angles to the axis of the ribbed cylinder (1). The mould (2) has a durable upper mould section (5) as part of the outer mould of the ribbed cylinder (1), and a supporting lower mould (6) to hold the inserted mould sections. The horizontal mould division is between the ribbed section (3) and the cylinder neck (4). The mould sections incorporate at least one drilling core (7) and pref. four vertical divided rib segment cores (8). The rib segment cores (8) have a thin wall thickness and are directly supported radially and axially on the supporting lower mould (6) section. The mould sections are loosely laid on the support section (6) from above, and are locked in place by the closing action of the durable upper mould section (5). The upper mould section (5) has a sprue (9) with filling openings (12) which cover the upper section (5) at the top. The mould (2) is mounted to a tilting chair (11) on a foundry turret. The durable upper mould section (5) and the lower support section (6) are moved, pref. mechanically, independently of each other.  The upper section (5) moves in the direction of the mould (2) axis, and the lower section (6) moves round an axis (13) of the tilting chair (11). ADVANTAGE - The mould provides different cooling actions along the length of the ribbed cylinder so that the whole component cools evenly without requiring any top-up. The ribs cool relatively rapidly, because of their thin wall structure, and the durable upper mould section gives faster cooling to the unribbed section of the cylinder through the good thermal conductivity of the durable mould section material.

Title: Oxygen consumption determn. in enclosed biological reactor - from pressure changes after receiving external oxygen
Inventor: SLAMA KAREL DR
IPC: C12M1/34
Filed: 1990-10-26
Abstract: Progress of reaction within a biological system including cellular material and tissue within a closed vessel (2) is determined by the vol. of O2 consumed and/or by CO2 evolved within a specific period. Data on these are derived by continuous measurements (11) of internal pressure submitted to an evaluation unit (3). O2 is supplied continuously or semi-continuously from a source (10) under the control of a circuit (12) receiving pressure data. Pressure drops due to O2 consumption in the closed vessel, or the increases due to CO2 evolation are established by comparison with a compensation vessel (1) and/or by controlled leakage into the atmos. O2 for the  reaction chamber may be produced electrolytically, while CO2 is fully absorbed. Pressure is transmitted from the closed vessel (2) to the evaluation unit via a membrane (16), e.g. 6-20 mm in dia. and 0.01-0.08 mm thick, and including semiconductor train-gauges for pressure activation. ADVANTAGE - O2 consumption and metabolics can be established with high sensitivity on small sample vols. over long periods, opt. with automation.
