Abstract: In such an installation, the reliability of response is to be increased. For this purpose, an hydraulic coupling 8, a valve 17 opening in dependence on the motor shaft speed and a container 15 for the operating fluid 21 of the hydraulic coupling 8 are provided. In one solution, the hydraulic coupling 8 is used as coupling between motor 9 and pump shaft 1. If an overspeed occurs, one half 7 of the coupling is emptied so that the force lock is interrupted. Another solution provides the use of an hydraulic coupling as brake. For this purpose, one half 7 of the coupling is attached to the free end 19 of the motor shaft 9, which half also carries out the rotation of the motor shaft. A second half 14 of the coupling is mounted on the stationary bearing 11 of the motor casing. In the case of an overspeed, the valve 17 opens so that operating fluid passes from the container 15 into the hydraulic coupling and a braking force lock occurs between the coupling halves. <IMAGE>

Abstract: 1. A method of measuring the frequency of an alternating electrical magnitude (U) by determining its zero passages and forming rectangular signals (ND) which are compared with counting pulses, and wherein the pulse sequence between two consecutive zero passages of the alternating magnitude is stored and converted in coded fashion into a voltage (U') proportional to the respective frequency of the alternating magnitude and constant between the zero passages, characterised in that in order to measure the frequency of an alternating magnitude which is of only a few Hz and has a strongly fluctuating amplitude, by determining the respective amplitude within each half cycle, the alternating magnitude (U) is controllably amplified in stages, subsequently rectified and its value (¦U¦) is compared with a predetermined maximal value (Umax), and the peak value (U) is formed from the value (¦U¦), and when obtaining the maximal value (Umax) and peak value (U) the amplification factor is respectively reduced by one stage, that the difference voltage (DELTA U) is formed from the peak value (U) and a value of the alternating magnitude and compared with a quotient (epsilon) of the peak value and an auxiliary voltage (Umin) which is amplification-controlled in the same manner, in synchronism with the alternating magnitude and the pulse sequence proportional to the time interval being obtained from the time interval between the occurrence of the peak value (U) and the equalization of the difference voltage to the quotient (epsilon).

Abstract: An apparatus for the automatic application of samples in thin-layer chromatography consists of a base (1) and an applying head (2) arranged above the base. The base supports two chromatography plates (7, 8) having surfaces of the same nature and a series of sample containers (6, 6', 6'', etc.). The applying head (2) carries a capillary (3) which is connected to a suction and pressure syringe (4). The applying head (2) can be displaced laterally with respect to the base (1), so that it can be brought above any desired position along the two chromatography plates (7, 8) and above any sample vessel (6, 6', 6''). Furthermore, the applying head (2) can be raised and lowered and swivelled about a vertical axis, so that the capillary (3) can be lowered onto any chromatography plate (7, 8) and into any sample vessel (6, 6', 6''). The process for the automatic application of samples using this device is characterised in that with the aid of the suction and pressure syringe (4) more sample liquid is charged into the capillary (3) than is required for application of the sample, and in that for the purposes of cleaning and accurate metering a small amount of sample liquid is firstly released onto one chromatography plate (8) before the actual application of the sample to the other chromatography plate (7) is performed. It is preferable to introduce a different liquid (rinsing or displacing liquid) into the capillary (3) before charging with the sample liquid. <IMAGE>

Abstract: The system comprises a light-transmission means for collecting and directing light to a foto-electric detector, which light emanates from a light beam scanning an original line-wise and which light is reflected by the original. 
     The light-transmission means consists of a light-transmitting body defined by two specular surfaces parallel to the line to be scanned and extending to the detector and by two specular side surfaces near the ends of the line to be scanned and perpendicular thereto. An internal reflection of said surfaces can be obtained by polishing the body at those places. 
     The light that would reach the detector by direct reflection at the surface of the original is eliminated by bringing about light polarisation effects, e.g. by using polarized light or by providing polarization filters in the path of light.

Abstract: A system for synchronising remote or colocated oscillators is constructed with redundancy enabling a high degree of fault toleration. In the various embodiments of the system there is no predetermined hierarchy amongst the oscillators in contrast to the prior art master and slave type of synchronisation. Averaging is not involved and the system settles to a state in which the oscillators are locked to one master, which is not predetermined. 
     Each oscillator is part of a terminal which includes reconfiguration circuitry, and each, in the absence of faults, is connected to each of the other terminals. The terminals attempt to lock to another oscillator and reconfigure in accordance with an algorithm until stable synchronisation is achieved. 
     In one embodiment the properties of a phase-locked loop are utilised in a novel way by incorporating a variable delay in its feed back path. Using this circuitry enables one embodiment to achieve synchronisation even when only indirect paths exist to the assumed master, and in the system temporary disconnection for reconfiguration is not necessary.

Abstract: A pipe coupling suitable plastics and metal gas pipes comprises a shell (11) having a portion (12) which is deformable radially inwardly by the application of hydraulic pressure to compress a gasket (15) and lock ring (28) into engagement with the pipe (23). The lock ring (28) has sharp teeth (34), and a recessed (36) periphery in which is received a protuberance (38) of the deformable shell (12). Permanent deformation of the protuberance (38) during installation of the coupling caused the teeth (34) to grip the pipe, and if tensile load is subsequently applied to the pipes, e.g. due to thermal effects, a ramp surface of the recess (36) engages the protuberance and thereby forces the teeth (34) into a tighter grip on the pipe section.

Abstract: Two essentially pure replicons, pHU1 and pHU2 (obtainable from ATCC 39195 and 39196), are produced by combining a cloning vector and insert DNA isolated from a biologically pure culture of the bacterium Rhizobium japonicum strain 122 DES. When either pHU1 or pHU2 is transferred into a point mutant strain of Rhizobium japonicum, PJ17nal (ATCC 39194), that lacks the capacity for synthesis of a hydrogen gas oxidizing system (Hup), the recipient strain PJ17nal, acquires the capacity for hydrogen gas oxidation. Similarly, transfer of the constructed replicons, pHU1 and pHU2, into another R. japonicum point mutant, PJ18nal (ATCC 39193), converts this strain into an H 2 -oxidizing strain. insert DNA in these replicons, therefore, contains genetic information essential for conversion of Hup- strains of Rhizobium to Hup + . Pure strains of nitrogen-fixing microorganisms containing the insert DNA. when administered to legumes, cause H 2  produced during nitrogen fixation to be oxidized and thereby increase the amount of energy available for nitrogen fixation.
