Patent DE-2624266-A1 (DE)
Title: Electrochemical measuring cells for gas-analytical measurements - uses addition of iodides to doping substance to cover immission and emission ranges
Inventor: KRONEISEN ARMIN DIPL CHEM DR
IPC: G01N27/49
Filed: 1976-05-29
Abstract: The electrolyte contains doping substances to reduce the transverse sensitivity of the cell towards accompanying gases in the gas sample which disturb the measurement. Iodine in the form of iodides is added as the doping substances. It does not matter whether the electrolyte is liquid or more or less consistent or whether it is organic or inorganic. Transverse sensitivity of an electrochemical cell can be reduced by 2 to 3 powers of ten. Sensitivity against HCN, HF, HCL and COCL2 is thereby reduced, so that these gases can accompany the gas sample without having a detrimental effect on the measurement.

Title: Interferometer for measuring surface flatness - has totally reflecting mirror mounted on sliding feeler carriage
Inventor: WILLHELM JOERG DIPL ING
IPC: G01B11/30
Filed: 1976-05-31
Abstract: The interferometer for measuring surface flatness comprises a light source (2) and semi-reflecting mirror (3). The emergent light is formed into a parallel beam by a condenser lens (4) and is split into two divergent rays by a grating (5). A second grating (6) reforms the rays into parallel paths, which are then totally reflected by an angle mirror or prism. (7) mounted on a measuring probe (8) which slides over the surface of the workpiece (1). Vertical displacements due to unevenness (15) are converted into interference patterns which are focussed by the lens onto photo-detectors (12-14) in an analyser (16). The direction of the displacement can be determined by oscillating the first grating in a perpendicular fashion and measuring the resultant phase-shifts of the beams.

Title: Disc brake for tractors - with automatic play adjustment by ratchet acting on threaded lever abutment bolt
Inventor: JANSEN WILHELM
IPC: F16D65/14
Filed: 1976-06-14
Abstract: A disc brake for agricultural and industrial tractors is designed so that the play in the links between the brake lever and the thrust plate for the brake disc can be adjusted sensitively, simply and without any necessity of maintenance. The lining wear can be also compensated by this method. The thrust plates are actuated through a toggle joint and a lever from the brake cylinder. The lever has a spherical recess for a ball on a bolt. A thread on the latter engages the thread in a blind bore of a boss on the brake housing. If excessive wear causes the pivot to be lifted too much, an L-shaped pawl moves the ratchet by one tooth and automatically lifts the bolt in compensation.

Inventor: ITO HIROSHI
IPC: G04B23/02
Filed: 1976-12-22
Abstract: The alarm time setting mechanism, for an alarm clock, uses a setting wheel (10) engaging a second setting wheel (8) for rotating an alarm indicator hand to the required alarm position. A release wheel (16) slides along the same shaft as the first setting wheel (10) and is rotated with the latter via a pin coupling (19,20) and driven via a wheel (7) of the clock mechanism. The first setting wheel (10) is also coupled to a further setting wheel (13) with a second release wheel (17) sliding along the same shaft as the latter and driven via a wheel (6) of the clock mechanism rotating at a higher rate. The second release wheel (17) can be rotated by the further setting wheel (13) via a second pin coupling (25,26). A contact device for the alarm is operated when the pairs of pins (19,20;25,26) of both setting wheels (10,13) engage in apertures (22,23;28,29) in the respective release wheels (16,17).
Patent DE-2707263-A1 (DE)
Title: Converter providing rectangular pulses from any shape train - has flip=flop followed by two integrators and differential amplifier fed back to flip=flop
Inventor: KORN JOEL DR
IPC: H03K5/156
Filed: 1977-02-19
Abstract: A converter receives a pulse train of any shape and converts them to rectangular pulses, having a constant, independent from frequency keying ratio (T). A flip-flop (G1, G2, R3, C3) is controlled by the input pulses. Its two outputs deliver complementary rectangular oscillations. The voltage dividing integrating circuits with division ratios (F1, F2) with F1/F2 = T, are connected to each flip-flop output. A differential amplifier (DV) delivers a signal proportional to the difference of the integrating circuits' signals. Its output is so fed back to the flip-flop, that its output signal automatically adjusts the length of the cycles to the set ratio.

Title: Indicator for testing inertial reel seat belt operation - has metal ball displaced from rest to complete electrical circuit
Inventor: SCHWANZ WILFRIED ING GRAD
IPC: B60Q1/44
Filed: 1977-03-30
Abstract: The indicator circuit for testing inertial-reel seat belts in motor vehicles comprises a heavy ball (2) which normally rests in the centre of a metal ring (3) in a container. A second ring with slightly higher walls (4) encloses the first. Each ring is connected to a battery powered lamp and/or bell circuit (6-8) fitted to the vehicle or test rig. When the acceleration forces, produced by braking or cornering etc. reach the limits corresponding to those at which the locking mechanism in the inertia-reel safety belt should come into operation, the ball is displaced from its central position and bridges the gap between the two concentric rings. The electrical circuit is completed and the lamp/bell indicator is energised.

The device consists of two pistons (3, 4) operated by a common drive (2) through a bevel gear system (1). Their cylinders (5, 6) are connected with each other and with the test sample (7) by a system of pipes (8) so that pressure variations in the test sample (7) correspond to the sum of volume changes in the two cylinders. The pressure cycles may be varied by adjustments in the timings of the two pistons.

Patent DE-2728177-A1 (DE)
Inventor: SCHAUB PAUL
IPC: A62C19/00
Filed: 1977-06-23
Abstract: The housing (2) of the fire-extinguishing alarm bomb resembles a tailor's dummy (1). It is made of cardboard or plastic and is filled with a powdery fire-extinguishing agent (3). An explosive charge (4) is located within the fire-extinguishing agent (3). Two fuse cords (5, 6) lead from the surface of the housing (2) to the explosive charge (4). So that the fire-extinguishing alarm bomb responds automatically when a fire breaks out, the explosive charge (4) is exploded by means of the burning fuse cords (5, 6). The fire-extinguishing agent (3) is thereby distributed in the burning room and the fire is extinguished. Moreover, the bang caused alerts the persons located in the vicinity. <IMAGE>
